[0025] Please refer to Figure 2 and Figure 3 One end of the moving column 204 is fixedly connected with the connecting block 207, both sides of the connecting block 207 being hingedly connected with a hinged seat 208, the hinged seat 208 being connected with the sliding column 209, the hinged seat 208 being installed to deform the sliding column 209 when the sliding column 209 is lowered, for buffering.
[0026] Please refer to Figure 2 and Figure 3 The inner wall of the box body 1 is fixedly installed with a partition plate 210, the top of the partition plate 210 being provided with a sliding groove 215 penetratingly formed, the sliding groove 215 being slidably connected with the sliding column 209, the sliding groove 215 being installed to trigger the trigger 11 when the sliding column 209 is lowered.
[0027] Please refer to Figure 2 and Figure 3 The top of the sliding column 209 is fixedly installed with a connecting disc 211, the top of the connecting disc 211 being fixedly connected with a sliding plate 212, the top of the partition plate 210 being fixedly installed with a spring 213, the top of the spring 213 being connected with the sliding plate 212, the sliding column 209 being located in the interior of the spring 213, the spring 213 being installed to generate a buffering force when the sliding column 209 is lowered, to avoid the sliding column 209 from being lowered too fast to damage the trigger 11.

[0029] The interior of the housing 1 is also equipped with a protective mechanism 3, which includes a protective shell 34 for protection.
[0030] Please see Figure 4 The protection mechanism 3 includes multiple support columns 31 fixedly installed on the bottom wall of the housing 1. Springs 32 are fixedly installed on the top of the multiple support columns 31. Pressing plates 33 are fixedly connected to the top of the multiple springs 32. The protective shell 34 is fixedly installed on the bottom wall of the housing 1. The trigger 11 is located inside the protective shell 34. The controller 35 is also fixedly installed on the bottom wall of the housing 1. The controller 35 is located on one side of the trigger 11. When the compensation chain falls, under the pressure of the weight, the sliding column 209 presses down on the pressing plate 33, causing the pressing plate 33 to compress the springs 32, thus achieving a buffering effect and preventing damage to the trigger 11 due to lack of buffering when triggered.

[0032] The implementation principle of a commercial elevator compensation chain breakage detection and protection device according to an embodiment of this application is as follows: A buffer triggering mechanism 2 is installed to trigger the trigger 11, causing it to alarm and notify personnel for repair. A protection mechanism 3 is installed to achieve a buffering effect, preventing damage to the trigger 11 due to insufficient buffering during triggering. Pulling the connecting block 207 causes the moving column 204 to slide inside the mounting cylinder 203, thereby pulling the spring 205 for buffering, allowing the sliding column 209 to move slowly downwards. The installed hinge seat 208 causes deformation of the sliding column 209 as it descends, further mitigating the impact. The sliding groove 215 is used to trigger the trigger 11 when the sliding column 209 descends. The spring 213 is installed to generate a buffering force when the sliding column 209 descends. Multiple sliding rods 214 are installed to maintain balance during descent. When the compensation chain falls, the weight presses down on the pressing plate 33, causing the pressing plate 33 to compress the spring 32, thus achieving a buffering effect and preventing damage to the trigger 11 due to lack of buffering when triggered. The controller 35 is used to send a signal to the external control console so that the staff can remotely detect the fault.
[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
