[0015] Figure 3 It is a schematic diagram of the internal structure of the present utility model.

[0016] Explanation of the reference numerals in the drawings:

[0017] Outer shell 1, outer cover 2, wiring shield 3, rotating shaft assembly 4, first bolt 5, roller assembly 6, second bolt 7, large gasket 8, rotating plate 9, travel switch assembly 10. Specific implementation manner

[0018] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the drawings. Only the preferred embodiments in the description are taken as examples. All other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0019] The following technical solutions are adopted in this specific implementation manner:

[0020] Please refer to Figures 1-3 , Embodiment 1 of this example includes an outer shell 1, an outer cover 2 and a wiring shield 3; an outer cover 2 is provided on the outer shell 1; a wiring shield 3 is provided on the outer shell 1;

[0021] It further includes:

[0022] Rotating shaft assembly 4, and the rotating shaft assembly 4 is connected to the outer shell 1 through a first bolt 5;

[0023] Roller assembly 6, and the roller assembly 6 is connected to the rotating shaft assembly 4 through a second bolt 7 and a large gasket 8;

[0024] Rotating plate 9, and the rotating plate 9 is arranged at the connection of the rotating shaft assembly 4 and the roller assembly 6;

[0025] Travel switch assembly 10, and the travel switch assembly 10 is arranged inside the outer shell 1, and the travel switch assembly 10 is connected to the roller assembly 6; the travel switch assembly 10 is electrically connected to the elevator.

[0026] When using the present utility model, when the steel belt of the steel belt elevator is loose or broken, the rope head will lift up and trigger the travel switch assembly 10 through the roller assembly 6 and the rotating shaft assembly 4, so that the elevator stops running, playing a role in protecting the safety of the elevator.

[0027] Compared with the prior art, the beneficial effects of the present utility model are:

[0028] 1. The prior art has two pairs of contacts, while the present utility model has one pair of contacts, namely the travel switch assembly 10, which saves costs;

[0029] 2. The prior art is fixed by two screws, while the present utility model is fixed by several (more than two) screws, which is more firm.

[0030] For those skilled in the art, they can modify the technical solutions described in the foregoing embodiments and perform equivalent replacements of some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
