Express cabinet door timing automatic closing device
The invention relates to the technical field of express delivery cabinets, and discloses an express cabinet door timing automatic closing device. The device comprises a box body; a first cylinder bodyand a second cylinder body are fixedly connected with the inner top wall of the box body; a ventilation hole is formed between the first cylinder body and the second cylinder body; a reset spring isfixedly connected with the inner top of the second cylinder body; a second piston is fixedly connected with the bottom of the reset spring; two ejector rods are inserted into the second piston; a rotating wheel and a winding roller are rotatably connected with the inner top wall of the second cylinder body; a clockwork spring is arranged in the winding roller; a second pull rope is wound around the exterior of the winding roller; and the top of the second pull rope is fixedly connected with an inserting block. The air pressure in the second cylinder body is increased, then the ejector rods clamp the inserting block, the air pressure in the second cylinder body is continuously increased to drive the second piston to move upwards, then the inserting block and the second pull rope drive the winding roller to rotate to wind the clockwork spring, and subsequent automatic door closing is facilitated.
本发明涉及快递柜技术领域，且公开了一种快递柜柜门定时自动关闭装置，包括箱体，所述箱体的内顶壁固定连接有第一缸体和第二缸体，所述第一缸体和第二缸体之间开设有换气孔，所述第二缸体的内顶部固定连接有复位弹簧，所述复位弹簧的底部固定连接有第二活塞，所述第二活塞的内部插接有两个顶杆，所述第二缸体的内顶壁转动连接有转动轮和绕线辊，所述绕线辊的内部设置有发条，所述绕线辊的外部缠绕有第二拉绳，所述第二拉绳的顶部固定连接有插块。通过第二缸体内的气压增大，进而使顶杆将插块卡住，第二缸体内的气压继续增大会带动第二活塞向上移动，进而通过插块和第二拉绳带动绕线辊转动给发条上劲，便于后续的自动关门。
