Description

Technical Field

[0001] The utility model relates to the technical field of elevator car bottoms, in particular to an elevator car bottom structure which is easy to maintain. Background Art

[0002] The elevator car bottom structure that is easy to maintain generally refers to the bottom structure of the elevator car. The car is a box-shaped space used by the elevator to carry and transport people and materials. The car is generally composed of main components such as the car bottom, car wall, car top, and car door. The car bottom is the car body component used by the elevator to carry passengers or cargo and other loads.

[0003] In the existing technology, such as the document with publication number CN112173926A, a kind of elevator car bottom structure which is easy to maintain is specifically disclosed. The elevator car bottom structure which is easy to maintain in the device includes a base frame and a bottom plate. In the prior art, the elevator bottom plate is mainly used to carry passengers or goods. Since the top of the bottom plate is squeezed by the goods for a long time, when the force on the top of the bottom plate is uneven, it will cause the bottom plate on the elevator bridge bottom structure to bend and deform. When the deformation of the bottom plate is more serious, the bottom plate needs to be disassembled and repaired. The bottom plates on the existing elevator bridge bottom structure are fixedly installed in the bridge bottom inner frame, or the bottom plates are fixed in the bridge bottom inner frame by bolts. This installation method is not convenient for disassembling the bottom plate, resulting in greater difficulty in repairing the bottom plate. For this reason, we propose an elevator car bottom structure which is easy to maintain. Utility Model Content
