Description

Technical Field

[0001] The utility model belongs to the technical field of elevator floor door anti-slipping structures, in particular to an elevator floor door anti-slipping structure with a buffer structure. Background Art

[0002] The elevator floor door is an important part of the elevator system. It is located at the entrance of each floor of the elevator shaft. It includes door leaves, door frames, door machine systems and other components. The main function of the elevator floor door is to ensure the safety of passengers. It will only open when the elevator car reaches the floor and the door machine system confirms safety to prevent passengers from accidentally falling into the shaft. During use, the elevator floor door may be derailed by external forces, causing the floor door to lose its safety protection function. The user may fall into the elevator shaft due to inattention in unknown circumstances, which may cause a safety accident. This requires adding an anti-slip structure to the structure of the elevator floor door. However, in actual use, some elevators do not add corresponding anti-slip structures, which causes great safety hazards.

[0003] Secondly, elevator landing doors without anti-slip structures are prone to malfunction and require frequent repair or replacement, which increases maintenance costs and downtime, affecting the overall operating efficiency and service quality of the elevator. If an elevator landing door derails during operation, it may not only cause the elevator to fail to operate normally, but may also cause personal injury to passengers entering and exiting the elevator.

[0004] In summary, there are some problems in the use of elevator floor doors without an anti-slip structure, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content

When the floor door body is subjected to external force, the anti-slip mechanism moves together, and the force it is subjected to can be buffered by several groups of spring damping shock absorbers, thereby protecting the floor door body.

[0012] As a preferred embodiment, an engaging block is provided at the upper end of the anti-slip mechanism, an engaging groove is provided on the lower surface of the landing door body, and connecting threaded holes are provided at the four corners of the inner side surface of the upper end of the engaging groove.
