Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:

as shown in fig. 1-8, the vertical hinged door includes a door frame 1, a door leaf 2 and a handle 3, the door leaf 2 is hinged in the door frame 1 through a driving shaft 21 and a bearing, and the handle 3 is installed in front of and behind the door leaf 2.

The utility model provides a vertical hinged door anti-pinch device, includes sleeve 4, wire rope 5, the location body 6, screw 7, lead screw 8, motor 10, spacing subassembly 9 and human infrared sensor 010, and wire rope 5 twines on sleeve 4, and sleeve 4 cup joints on drive shaft 21, and wire rope 5 links to each other with the

location body

6, and 6 rigid couplings of the location body are on screw 7,

screw

7 and 8 threaded connection of lead screw, and lead screw 8 links to each other with motor 10. The motor 10 drives the screw rod 8 to rotate forward and backward to drive the screw nut 7 and the positioning body 6 to move back and forth, the positioning body 6 drives the sleeve 4 and the driving shaft 21 to rotate forward and backward through the steel wire rope 5 to drive the door leaf 2 to rotate anticlockwise or clockwise to open and close the door.

The doorframe 1 is composed of a top beam 11, a bottom frame 12 and two upright posts 13 fixedly connected between the top beam 11 and the bottom frame 12. The top beam 11 is provided with an installation groove 111, and the sleeve 4, the steel wire rope 5, the positioning body 6, the nut 7, the lead screw 8 and the motor 10 are installed in the installation groove 111.
