Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] This utility model provides, for example Figures 1-4 The elevator car bottom shown has a multi-level buffer protection function. The bottom of the elevator car bottom body 1 has a square groove, which is conducive to the placement of the first buffer component 2 and the second buffer component 3. The first buffer component 2 and the second buffer component 3 are disposed inside the square groove. The composition and structure of the first buffer component 2 and the second buffer component 3 are consistent with the prior art and will not be described in detail here. The first buffer component 2 and the second buffer component 3 are used to buffer and protect the elevator car bottom body 1. The connecting mechanism 4 is disposed inside the square groove. The connecting mechanism 4 is used to separate the first buffer component 2 and the second buffer component 3 from the elevator car bottom body 1.

[0042] Furthermore, the connecting mechanism 4 includes a support frame 41, a sliding column 43, a limiting plate 44, and a connector. The support frame 41 facilitates the installation and support of the first buffer assembly 2 and the second buffer assembly 3, making it easy to remove and install the first buffer assembly 2 and the second buffer assembly 3 together. The sliding column 43 provides vertical guidance for the installation of the support frame 41. The limiting plate 44 limits the relative position of the elevator car bottom body 1 and the sliding column 43, thereby facilitating the installation and disassembly of the support frame 41, so that the first buffer assembly 2 and the second buffer assembly 3 can be removed and maintained together without being limited by maintenance space, making installation and operation convenient. The support frame 41 slides through the inside of the square groove. The first buffer assembly 2 and the second buffer assembly 3 are both installed inside the support frame 41. The sliding column 43 is fixedly connected to the side of the support frame 41. The limiting plate 44 is slidably disposed on the side of the elevator car bottom body 1, with the end of the limiting plate 44 located on the sliding column 43. The connector is disposed on the limiting plate 44.

[0043] Furthermore, the connecting mechanism 4 also includes a sliding groove, a through groove, a limiting groove, and a positioning plate 42. The positioning plate 42 is beneficial for positioning the installation of the bearing frame 41 to increase the stability of the installation of the bearing frame 41. The sliding groove is opened on the inner wall of the square groove, and the sliding column 43 is slidably inserted into the inner cavity of the sliding groove. The through groove is opened on the inner wall of the sliding groove, and the limiting plate 44 is slidably inserted into the inner cavity of the through groove. The limiting groove is opened on the side of the sliding column 43, and the limiting plate 44 is slidably inserted into the inner cavity of the limiting groove. The positioning plate 42 is fixedly connected to the top of the bearing frame 41, and a positioning groove adapted to the positioning plate 42 is opened at the top of the inner wall of the square groove.

[0044] Specifically, the connecting components include a vertical plate 45, a mounting column 46, a threaded seat 47, and a rotating head 412. The vertical plate 45 is beneficial for supporting the limiting plate 44 and facilitating the movement of the limiting plate 44. The mounting column 46 is beneficial for connecting with the threaded seat 47 to connect and fix the vertical plate 45, preventing the limiting plate 44 from sliding freely. The rotating head 412 is beneficial for rotating and limiting the mounting column 46, facilitating operation. The vertical plate 45 is fixedly sleeved on the outside of the limiting plate 44. The mounting column 46 is rotatably inserted into the side of the vertical plate 45. The threaded seat 47 is fixedly embedded in the side of the elevator car bottom body 1.
