[0002] With the development of economy, the design of elevator car pays more and more attention to industrial design, requiring neat and beautiful appearance. Generally, the panel of elevator control box is also the front wall of the car, and the panel needs to be connected and fixed with the box of the control box by fasteners, so that the panel can be rotated and opened for maintenance after loosening the fasteners. However, the fasteners or disassembly holes of the panel are exposed on the decorative surface, which will destroy the decorativeness of the panel, which is very unsightly and affects the decorative effect of the car.

[0003] For example, an invention patent with application number CN201810252911.1 provides an elevator car and an elevator control box, the elevator control box includes a box body with an opening, a panel, a lining, a rotatable connecting piece and a snap mechanism, the panel cover is arranged at the opening of the box body, the lining plate is fixed on the inner surface of the panel facing the box body, and the lining plate includes a first end and a second end arranged opposite to each other, the rotatable connecting piece is connected between the first end and the box body, the snap mechanism is arranged at the joint between the second end and the box body, when the second end rotates around the rotatable connecting piece in a direction close to the box body, the snap mechanism connects the box body and the lining plate, and when the second end rotates around the rotatable connecting piece in a direction away from the box body, the snap mechanism allows the box body and the lining plate to be separated.

[0004] In summary, although some existing technical solutions have good decorative effects, their structures are relatively complex and the cost of the structures used is relatively high, leaving much room for improvement. Summary of the invention

[0005] The purpose of the utility model is to solve the above problems in the prior art and to propose an elevator car control box.
