Anti-collision electric retractable door

Abstract

The invention relates to an anti-collision electric retractable door. The door specifically comprises a main door post; one side of the main door post is fixedly connected with a wall; a movable doorframe and a power machine head are fixedly connected through a plurality of telescopic fixing strips and telescopic frames; limiting guide rails are arranged at the bottoms of the movable door frame and the power machine head; limiting blocks are arranged in the limiting guide rails; sliding blocks are arranged at the bottom of the movable door frame and located on the limiting blocks; limiting devices are arranged between the bottoms of the limiting guide rails; the bottoms of the limiting devices are connected with the ground; the limiting guide rails are arranged in grooves in the ground; and a plurality of limiting strips are arranged at the two sides of the bottoms of the limiting guide rails. A lever structure resists impact in the forward direction and the reverse direction, plays arole in stabilizing and supporting, prevents the retractable door from deviating from the rails, guarantees the safety of the retractable door, effectively avoids damage caused by extrusion of a vehicle due to the use of the limiting guide rail structures, and accordingly can play a good anti-collision role.

Description

technical field [0001] The invention relates to the technical field of electric telescopic doors, in particular to an anti-collision electric telescopic door. Background technique [0002] At present, the electric telescopic door is a common facility in public places. It generally includes a door body pulled by a motor head, a door post, and a door warehouse. The door body is composed of a telescopic frame. It saves a certain space and keeps the overall appearance of the gate. The operator only needs to press the remote control button to complete the opening and closing of the electric telescopic door, which greatly saves manpower. However, the bottom of this traditional electric telescopic door is not well fixed. The device fixes it, and it will be detached from the track when it is slightly squeezed after unfolding. It is difficult to expand and contract after deviating from the track. Frequent use of offset will damage the bottom parts of the electric telescopic door, res...

However, the bottom of this traditional electric telescopic door is not well fixed. The device fixes it, and it will be detached from the track when it is slightly squeezed after unfolding. It is difficult to expand and contract after deviating from the track. Frequent use of offset will damage the bottom parts of the electric telescopic door, resulting in great losses.
