An embodiment of the invention relates to a photoelectric detection device and a physiological information detection device. The photoelectric detection device comprises a supporting part, a light receiving component, light emitting components and a light permeable part. The light receiving component and the light emitting components are arranged on the supporting part, and the light emitting components are positioned around the light receiving component. The light permeable part is positioned on the supporting part, externally covers the light receiving component and the light emitting components, allows light emitted by the light emitting components to permeate to reach a detected object and allows light reflected by the detected object to permeate. A shell surface, contacting with the detected object, of the light permeable part comprises a convex light permeable curved surface and a light permeable plane at the top of the light permeable curved surface. A shell surface, contacting with the detected object, of the supporting part comprises push contact portions, the push contact portions are isolated from the light permeable part and positioned around the light permeable part, and a height H1 of the light permeable part in the vertical direction and a height H2 of the push contact portions of the supporting part in the vertical direction meet a condition of H1>H2>0. The photoelectric detection device and the physiological information detection device have advantages that wearing comfort of human bodies can be improved, and discomfort is avoided.

The invention relates to the technical field of fluid pumps, and discloses a low-loss peristaltic pump, which includes a pump head, a driver and a hose. tube, and the inner cavity of the extruded tube is covered with a hose and an extruded ball. The low-loss peristaltic pump, due to the randomness of the extrusion ball cutting angle, the mutual extrusion surface between the moving hose and the extrusion ball is also random, the extrusion ball is relatively uniform in pressure, and the material fatigue caused by bending The wear and tear are evenly distributed on the surface of the hose, its service life is greatly improved, and its elastic properties can also be kept unchanged for a longer working time to maintain stable operation. Secondly, the hose, squeeze tube and squeeze ball The size parameters of the hose are fixed, and the extrusion force between the hose and the extrusion ball is relatively stable. At the same time, because the extrusion ball is deformable, it will also absorb excessive pressure, and the bending degree of the hose is always kept in a reasonable range. Inside.

The invention relates to the field of plywood production equipment, in particular to a press-forming machine for plywood production and a method for using the same, including a base on which an extrusion mechanism for pressing the plywood and a pressure applying mechanism capable of adjusting the pressure are arranged. The pressing mechanism is used to place the plywood after being glued and to be pressed and shaped. The pressing mechanism is connected with the extrusion mechanism. The extrusion mechanism is equipped with a distance adjustment mechanism for adjusting the pressing distance. connect. The press forming machine for plywood production and its use method drive the extruding mechanism to squeeze the glued plywood through the pressing mechanism, so that the plywood is pressed thin after being stressed, and the air and excess glue are discharged, thereby making the plywood thin. The plywood is pressed and shaped, and the entire pressing process realizes continuous pressing and shaping of the plywood, which is stable and reliable, improves production safety, and can also help to improve the shaping effect and efficiency of the plywood.

The invention relates to the field of medical devices, and particularly discloses an ambulance stretcher ladder board. The ambulance Stretcher ladder board comprises a ladder board body, an air cylinder and an air compressor. One end of the ladder board body is hinged to an ambulance bottom plate through an articulated shaft; the cylinder body of the air cylinder is hinged to the ambulance bottomplate, and a push arm hinged to a piston rod of the air cylinder is fixed to the ladder board body; two parallel slide rails are arranged on the surface of the ladder board body , multiple limiting units are arranged between the slide rails, and each limiting unit comprises a nozzle, a limiting plate and a limiting edge which are arranged from the hinged end to the free end in sequence; the ladderboard body is provided with a notch in which the nozzles are arranged; one end of each limiting plate is hinged to the two side walls of the notch, the limiting plates can cover the nozzles, and theair compressor and the nozzles are communicated through solenoid valves; the free end of the ladder board body is provided with control parts located in the slide rails, each control part comprises acontrol rod, a balance spring, a first press switch and a controller electrically connected to the solenoid valves, and the cylinder body of the air cylinder is provided with second press switches electrically connected to the controllers. Through the ambulance stretcher ladder board, the safety can be improved.

The invention discloses a frying and baking device with a micro-pressure function. The frying device comprises an upper baking tray set, a lower baking tray set and a micro-pressure mechanism, wherein the micro-pressure mechanism comprises a rotating lifting rod, two arc guide rails and two sets of locating slots, wherein the rotating lifting rod comprises two rear lifting rods and a front lifting rod; the two rear lifting rods are fixed on the upper baking tray set; two arms of the front lifting rod are connected with the two rear lifting rods rotationally and are rotated along two sides of the upper baking tray set; two arms of the front lifting rod are respectively provided with a pressure spring, a pressing buckle which is arranged on the inner sides of two end parts of the front lifting rod respectively and is used for pressing or loosening the pressure spring, and a locating pin; the two arc guide rails are arranged on two sides of the lower baking tray set and is used for clamping the pressing buckle; and the two sets of locating slots are formed on the two sides of the lower baking tray set and are used for fixing the locating pin. Through the technical scheme, the frying and baking device with the micro-pressure function has the advantage of providing greater force when food is extruded due to the micro-pressure mechanism to ensure that the extrusion effect is better.

A vibration insulation damper (10, 50, 60) insertable into an internal circumferential portion of a coil spring (20) and extending in an axial direction thereof, the vibration insulation damper is provided with an elastic body (14a, 14b, 64a, 64b) having a conical or pyramid outer circumferential surface formed so as to be shortened in distance with respect to the axial direction toward an end portion thereof in the axial direction, and a rib (16a, 16b, 16c, 16d, 16e, 16f, 56a, 56b, 56c, 56d, 56e, 56f) protruding outward from the outer circumferential surface of the elastic body to be brought into pressured contact with the internal circumferential portion of the coil spring when the elastic body is inserted into the internal circumferential portion of the coil spring.
