DETAILED DESCRIPTION

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0023] In view of the technical problems in the background technology, the embodiment of the utility model provides an elevator anti-falling structure, such as Figures 1 to 2 As shown, in one embodiment, the elevator anti-falling structure includes a driving assembly, an anti-falling bracket 13, a bearing platform and a self-locking spring 14. The driving assembly and the self-locking spring 14 are arranged below the elevator bottom plate 17 in the horizontal direction, the bearing platform is fixed to the side edge of the elevator car door sill 20 close to the floor door, the anti-falling bracket 13 is arranged on the bearing platform so as to be horizontally movable, and one end of the self-locking spring 14 is connected to the side plate of the anti-falling bracket 13 away from the floor door to achieve the reset action of the anti-falling bracket 13. The output end of the driving assembly is connected to the side plate of the anti-falling bracket 13 away from the floor door, and is used to drive the anti-falling bracket 13 to move horizontally toward the floor door, so that the anti-falling bracket 13 blocks the gap between the car door sill 20 and the floor door sill 21, and the anti-falling bracket 13 can receive small items that fall into the gap.

[0024] Specifically, the bearing platform includes a car door footboard 15 and a bearing plate 16. The car door footboard 15 is fixed to the edge of one side of the elevator car door sill 20 close to the landing door. The bearing plate 16 is horizontally arranged on the side of the car door footboard 15 close to the elevator bottom plate 17. The anti-fall bracket 13 is slidably arranged on the bearing plate 16. The car door footboard 15 is provided with a protruding opening 22, and the protruding opening 22 is directly opposite to the anti-fall bracket 13. The conventional car door footboard 15 structure is used, and the bearing plate 16 is added to the structure to form the above-mentioned bearing platform, which simplifies the required installation space, reduces the production cost, and is easy to process.

[0025] In one embodiment, the driving assembly includes a driver 10, a guide wheel 12 and a wire rope 11. The door footboard 15 is provided with a mounting position, the guide wheel 12 is arranged at the mounting position 23 through the wheel shaft, the wire rope 11 is sleeved on the guide wheel 12, one end of the wire rope 11 is connected to the driver 10, and the other end of the wire rope 11 is connected to the side plate of the anti-fall bracket 13 away from the landing door, and the installation position of the driver 10 can be conveniently selected through the guiding effect of the guide wheel 12, which is convenient for the assembly and disassembly of the driver 10.

[0026] Preferably, the driver 10 is a lifting motor, which drives the wire rope 11 to move, thereby pulling the anti-fall bracket 13 out of the extension opening 22 to cover the gap between the car door sill 20 and the landing door sill 21.

[0027] In one embodiment, the elevator anti-falling structure also includes a limiting component, which includes a floor door toe guard 18 and a travel switch 19. The floor door toe guard 18 is fixed to the side edge of the floor door sill 21 close to the elevator door. The travel switch 19 is arranged on the floor door toe guard 18 and is located on the moving path of the anti-falling bracket 13. The travel switch 19 is used to feedback a signal to control the displacement distance of the anti-falling bracket 13.

[0028] The working process of the elevator anti-falling structure of the utility model embodiment is as follows:

[0029] like Figures 3 to 4 As shown, when the elevator is ascending or descending, the driver 10 does not work, and the anti-fall bracket 13 is in a retracted state under the action of the self-locking spring 14. When the elevator reaches a floor, the driver 10 drives the anti-fall bracket 13 to move, and it extends from the extension port 22 under the force of the self-locking spring 14, and the travel switch 19 sends a feedback signal to control the moving distance of the anti-fall bracket 13, so that the anti-fall bracket 13 blocks the gap between the car door sill 20 and the floor door sill 21, and receives small items that fall into the gap.

[0030] The embodiment of the utility model also protects an elevator, which includes the elevator anti-article falling structure in any one of the above embodiments.

[0031] Compared with the prior art, the beneficial effects of an elevator object-falling prevention structure of the utility model embodiment are as follows:

[0032] An elevator object-falling prevention structure according to an embodiment of the utility model drives an anti-falling bracket to perform telescopic displacement through the action of a driving component and a self-locking spring, so that when the elevator is leveled, the anti-falling bracket blocks the gap between the car door sill and the floor door sill, preventing small objects from falling into the elevator shaft through the gap.

[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
