Anti-pinch device for automatic door
The invention provides an anti-pinch device for an automatic door. The anti-pinch device comprises a roller, connecting pieces and a buffering assembly, wherein the roller is in a solid or hollow cylinder shape, the connecting pieces are arranged at the two ends of the roller respectively and each provided with a cylindrical protrusion used for being movably connected with the roller, round grooves are formed in the two ends of the roller, the protrusions are embedded into the round grooves respectively, the roller rotates around the protrusions at the two ends, and the connecting pieces are square and provided with through holes; the buffering assembly comprises fixing rods and springs, when an object is pinched in the closing process of the automatic door, the roller moves in the opposite direction of the object and compresses the springs for buffering, the object is pulled outwards to make the roller rotate, and then the object is taken out. The anti-pinch device does not depend on high-cost electronic information equipment, the object is not prone to being pinched when the automatic door is closed, and the preconceived target is achieved on the basis of considering economic cost benefits.
