The invention relates to an injection head device of a continuous string coiled tubing, which comprises clamping cylinders, tensioning cylinders, drive sprocket wheels, saddle shaped clamping blocks and chains. A cylinder head and a piston rod head of three pairs of clamping cylinders of the device are respectively connected through a shaft, a bearing bracket which can rotate on the shaft is arranged on each shaft, a sliding block is respectively arranged on both ends of the shaft, a bearing frame body which can rotate on a pin roll is respectively arranged on two end of each bearing bracket through the pin roll, and a clamping bearing which can rotate on the pin roll is respectively arranged on each bearing frame body through the pin roll. A plurality of clamping bearings are separated into three parts relatively independent, a clamping mechanism is separately controlled by three sets of clamping cylinders respectively, so that when the injection head goes up and down the continuous string coiled tubing, the upper clamping cylinder, the middle clamping cylinder and the lower clamping cylinder can sequentially load pressure or unload pressure. As a result, the clamping force can concentrate on the three parts so as to ensure that when the continuous string coiled tubing is clamped, strong clamping force can be generated, and the loading force is balanced without deflection and can be easily aligned with the well head. Therefore, the invention solves the technical problem of difficult alignment with the well head during operation of the continuous string coiled tubing operation device for quite a long time.

A hydraulic bolt lifting device comprises a movable ring beam (2), a fixed ring beam (7) and a pile fixing frame (9), wherein the pile fixing frame (9) is connected with the upper end of the fixed ring beam (7) through connecting supports (8), the fixed ring beam (7) is connected with one end of each supporting rod (6) through a hinging shaft, the other end of each supporting rod (6) is hinged to a corresponding outer side telescopic end of a double-extend-out oil cylinder (4), the middle of the double-extend-out oil cylinder (4) is fixed to the movable ring beam (2) located under the double-extend-out oil cylinder (4) through an oil cylinder connecting plate (3), and the outer side telescopic ends of the double-extend-out oil cylinder (4) are respectively connected with the upper end of a sliding support (5). The hydraulic bolt lifting device is reasonable in structure, can ascend and descend through the successive coordinated motions of the movable ring beam and the fixed ring beam, the double-extend-out oil cylinder and a motion assembly of the double-extend-out oil cylinder are adopted, so that the hydraulic bolt lifting device operates stably and reliably, a platform will not incline and can be corrected itself even when inclination occurs, and the lifting efficiency is high.

The invention provides a lead delay element rotary cutter which comprises a rotary cutting assembly, a feeding detection mechanism, a horizontal and vertical straightening mechanism, a tensioning device, a linear (or disc type) wire inlet platform and an industrial personal computer which are all arranged on a worktable. A lead delay cord is driven by the feeding detection mechanism which is driven by a stepping motor and straightened by the straightening mechanism, passes a hollow lead delay cord fixing shaft of the rotary cutting assembly and then butts against the rotary cutting position, a high-accuracy coder detects required cutting length information and then sends instructions to rotary cutting blades, a rotary cutting cylinder arranged on the rotary cutting assembly pushes the rotary cutting blades to radially move towards the axis of the lead delay cord fixing shaft to cut off the lead delay cord, and rotary cutting is completed. The radially symmetrically arranged rotary cutting blades and rotary cutting riding wheels simultaneously apply force in the axis direction on the circumference of the lead delay cord, radial thrust in all directions is offset, the section of a cut lead delay element is level and does not deform, U-shaped section cannot be formed, and product scraps are few.

The invention discloses a kind of no leakage and pure water flat electro-hydraulic directional control valve. A king valve cover is in the heart of the king valve and flat king valve core compacted by a spring lies in the cavity of axial of the king valve body; on the upper of king valve body there is a water inlet and a water outlet connected by the king valve's channel; in the king valve there is a sensitive cavity connected with electromagnetic ball valve by tunnels; a valve port damper installed at the valve entrance of electromagnetic ball valve matches with the sensitive cavity of king valve in order to control the flow velocity of fluid and reduce directional strike at the same time diverting fast. The invention adopt flat king valve core set on the packing force of the king valve cover and increase dramatically valve covers, adopt direct seal to realize zero leakage; divert fast and steadily through matching the sensitive cavity of king valve with the damper at the entrance of the electromagnetic ball valve; not change the structure of the king valve and only change structural form of electromagnetic ball valve in order to have different functions and fit to work under conditions of middle and high pressure water medium.

The invention discloses a slitting machine for glass products, wherein the back side of the machine table is further provided with a roller support mechanism, a side positioning mechanism and a longitudinal film loading mechanism. The bottoms of the mounting strips on both sides are installed with pressing plates that protrude toward the outside. The side positioning mechanism includes a positioning shaft that is rotatably installed on the rear side of the machine table. The positioning shaft is fixedly installed with a rotating plate and an L-shaped. Positioning and mounting plate, the rotating flat plate protrudes toward the inside of the slitting machine, the L-shaped positioning mounting plate protrudes toward the outside of the slitting machine, and the pressing plate presses against the rotating flat plate when the mounting strip is lowered The positioning shaft rotates, and a side positioning assembly is fixedly installed at the end of the L-shaped positioning and mounting plate, and the positioning surface of the side positioning assembly is parallel to the rotating plate. The invention can realize the lateral positioning of the glass during automatic feeding of glass cutting, reduces the positioning steps, and is not easily affected by the failure of the sensor.

The invention discloses a bendable laryngeal mask with a positioning guide core and a use method thereof, comprising a laryngeal mask body, a positioning guide core and a disposable transparent protective cover; the laryngeal mask body includes a ventilation tube and a mask connected with it body, the positioning guide core can be placed into the ventilation tube; the positioning guide core includes a bendable mirror body with adjustable bending arc; a limit assembly that can fix the bendable mirror body and the ventilation tube is provided on the bendable mirror body When in use, the flexible mirror body with a disposable transparent protective cover is inserted into the ventilation tube, and placed in the mouth and pharynx along with the laryngeal mask, and the limiting component can prevent relative displacement between the flexible mirror body and the ventilation tube. The advantage of the present invention is that the tightness of the contact between the ventilation tube and the flexible mirror body is controlled by the limit assembly, which improves the force conduction, not only can significantly improve the success rate and insertion quality of the flexible laryngeal mask for the first time, but also Can ensure full visibility.

The invention relates to an electrothermal cooking appliance with uniform heating, which comprises a pan body and a reflecting cover, wherein the pan body is placed in the reflecting cover, guiding convex grooves are arranged on the side wall of the reflecting cover, and the number of the guiding convex grooves is at least two. According to the electrothermal cooking appliance with uniform heating, the side wall of the reflecting cover is provided with the guiding convex grooves, and the pan body can be placed into the reflecting cover more smoothly by the structures of the guiding convex grooves. Meanwhile, the pan body and the reflecting cover are fixed by the guiding convex grooves, so that the comparatively accurate concentricity of the pan body in the reflecting cover can be kept, the phenomenon of deflexion can not occur, and the aim of uniform heating is realized.
