[0005] The main purpose of the utility model is to provide an anti-collision device for an elevator car, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] An anti-collision device for an elevator car comprises a first rectangular frame, the left and right ends of the first rectangular frame are both equipped with mounting seats, an adjustment component is provided in the middle of the upper end of the first rectangular frame, the adjustment component extends into the first rectangular frame, the front end of the adjustment component is fixedly connected to a second rectangular frame, a plurality of support rods distributed in a linear array are commonly installed between the upper inner wall and the lower inner wall of the second rectangular frame, and the outer cylindrical surfaces of the plurality of support rods are all sleeved with anti-collision components.

[0012] Preferably, the upper ends of the two mounting seats are threadedly inserted with screws.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The anti-collision performance of the elevator interior can be improved by setting anti-collision components. When the truck is about to contact the elevator car, the truck first contacts the anti-collision cylinder. The anti-collision cylinder absorbs the impact force during the collision through its own deformation, reducing the impact force transmitted to the inner wall of the elevator car. After the collision, the anti-collision cylinder restores its original shape through its own elasticity, avoiding damage to the inner wall caused by direct contact between the truck and the inner wall of the car. Frequent maintenance and replacement are not required, reducing maintenance costs and staff workload. At the same time, the anti-collision cylinder can rotate. When colliding, the anti-collision cylinder can guide the impacting object to move to other directions by rotating, avoiding continuous collision with the same position of the anti-collision cylinder;

[0015] 2. The height of the anti-collision component can be adjusted by setting an adjustment component. When the height needs to be adjusted, the knob is turned to drive the screw to rotate, and the screw drives the connecting plate to move. The connecting plate drives the anti-collision component to move up and down through the second rectangular frame. The height of the anti-collision component can be adjusted at any time according to actual needs, so as to adapt to different scenes and different sizes of goods entering and exiting, thereby improving the flexibility and convenience of operation.
