The invention belongs to the technical field of guardrail production, and concretely discloses a spraying device for guardrail production. The spraying device comprises a spraying chamber, a fixing mechanism, a supporting mechanism and a power mechanism. The fixing mechanism comprises an installation plate, a fixed column, a rotary plate and multiple fixing units; multiple rotary teeth are arranged on the circumference of the installation plate; each fixing unit comprises two expansion blocks and two connecting rods; the expansion blocks are slidably connected onto the installation plate; oneends of the two connecting rods are hinged onto the different expansion blocks; the other ends of the two connecting rods are hinged onto a fixing rod; supporting units are arranged on the supportingmechanism and are arranged opposite to the fixing units; the power mechanism comprises a threaded rod and a motor; a sliding plate and a carrying plate are in threaded connection onto the threaded rod; a first spray head is fixed onto a sliding block; a straight rod is arranged on the carrying plate; a second spray head is fixed onto the straight rod; and a gear is fixed onto the threaded rod andis located above the installation plate. By using the spraying device, the problem that a surface of a guardrail component is nonuniformly sprayed can be effectively solved.

The invention relates to an anti-explosion keyboard, in particular to an anti-seepage, anti-deformation and anti-explosion keyboard which comprises a housing, a cover plate is arranged at an opening in the lower end of the housing, a circuit board is arranged in the housing, keys are further arranged on the housing and matched with the circuit board, a surface anti-seepage device is arranged outside the housing, and through the surface anti-seepage device, water and dust can be prevented from entering gaps between the keys and the cover shell from the upper surface, a good sealing effect is further achieved, a key anti-seepage device is arranged between the cover shell and the keys, a gap anti-seepage device is arranged between the cover shell and the cover plate, waterproof blocking can be formed, meanwhile, the deformation resistance strength of the edge of the cover plate can be improved, the protruding edges can form positioning in the installation process, then it is guaranteed that the cover plate and the cover shell are right opposite in position, an anti-seepage supporting device is arranged at the lower end of the cover plate, the keyboard can be separated from the platform, then water can be prevented from entering the cover shell from a gap between the cover plate and the cover shell, and the anti-seepage purpose is achieved.

The invention discloses a lead frame die switching device, a main body seat, a sliding plate is slidably connected on the upper surface of the main body seat, three molds are detachably connected on the upper surface of the sliding plate, and a punching plate is arranged on the upper surface of the main body seat The main body seat is provided with a quick switching mechanism; the quick switching mechanism includes a sliding groove opened in the main body seat, and a sliding block is slidably connected in the sliding groove, and the sliding block is connected to the lower surface of the sliding plate. Fixed connection, two sliding sleeves are fixedly connected through the main body seat, and connecting blocks are sealed and slidably connected in the sliding sleeve, and the two connecting blocks are respectively fixedly connected with the two side walls opposite to the slider. The advantages are: the switching device of the present invention can quickly switch the mold in the continuous high-speed stamping process, thereby improving the processing efficiency, and the position of the mold after switching is accurate, ensuring the processing quality, and at the same time, it can buffer part of the stamping process. impulse, protective device.

The invention relates to an easy-to-use cooking utensil, which comprises a body, an inner pot with a cooking cavity and a detachably connected inner cover, the inner cover includes a frame body, a sealing ring and a metal cover body, and the frame body is compressed and sealed ring to fix it on the outer periphery of the metal cover, and the frame body extends outward to form a convex portion, and the convex portion is provided with a steam valve, and the steam valve includes an air inlet and an exhaust port, and the air inlet It is arranged on the metal cover body, and the exhaust port is arranged on the convex part facing downward. Adopting this technical solution, the steam valve and the inner cover can be disassembled and cleaned as a whole, which can avoid the problem that many cleaning parts may cause missing installation; The condensed water can be discharged directly through the exhaust port of the steam valve, preventing the condensed water from accumulating in the steam valve or flowing back into the cooking cavity and affecting food hygiene.

The invention discloses a power testing system for a complete machine of a new energy vehicle, comprising a workbench. A lift frame capable of driving the new energy vehicle to move along the height is arranged on the workbench. The workbench corresponds to the four wheel hubs of the new energy vehicle. Four attitude frames that can move radially and / or axially, the attitude frame is provided with a rotating head that can adjust the angle of pitching and radial fine-tuning, and one end of the rotating head is provided with a detachable connection with the wheel hub of the new energy vehicle after lifting The other end is provided with a transmission shaft connected with the power device in the dynamometer. The power device can drive the wheel hub of the new energy vehicle to rotate through the rotating shaft; battery simulation system, lift control system, road simulation system, information acquisition system and The dynamometers are respectively electrically connected with the overall control system, and the overall control system generates control signals for control; the battery simulation system is connected to drive the hub of the new energy vehicle to rotate, and the rotating head changes with the attitude of the hub of the new energy vehicle.

The invention discloses a control system for vertical circulation three-dimensional parking equipment, which includes a base, an inclined seat, a support frame, a slideway, a servo motor, a transmission turntable and a parking seat. The support frames are symmetrically installed on both sides of the top of the base, and one side An inclined seat is installed at the bottom of the support frame, and the inner sides of the support frames on both sides are connected and fixed by several connecting columns, and slideways are installed on the inner sides of the support frames on both sides; the present invention accurately positions the parking seat, and is Then move the unmanned car to the parking seat and make preparations to ensure that the skateboard can move to the inclined seat accurately and stably. In the case of unmanned driving, the car will be automatically parked through the operation of the vertical circulation three-dimensional parking equipment, which greatly improves the The convenience of use is improved, the complexity of operation is reduced, and the parking seat is limited and fixed to avoid sudden parking and the shaking of the parking seat, ensuring that the car is safely and stably parked on the parking seat.
