[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] This utility model provides, for example Figures 1-4The elevator car buffer installation structure shown includes a shaft 1, a mounting box 2, and an unlocking mechanism. A buffer 3 is installed inside the shaft 1, and the mounting box 2 serves as the mounting base for the buffer 3. The buffer 3 provides buffer protection for the elevator car. The main structure of the buffer 3 includes a cylinder, a plunger, a return spring, and a buffer pad. The mounting box 2 is movably connected to the inner cavity of the shaft 1, and the buffer 3 is fixedly connected to the top of the mounting box 2. An installation groove 5 is provided inside the inner cavity of the shaft 1, and multiple mounting blocks 6 and mounting grooves 5 are provided inside the mounting box 2. The mounting grooves 5 are trapezoidal grooves, and the mounting blocks 6 are trapezoidal blocks. The mounting box 2 is pushed into the shaft 1. When the installation box 2 is installed inside the shaft 1, the inclined surfaces of multiple mounting blocks 6 are in contact with the inclined surfaces of the mounting groove 5. The mounting groove 5 can push the mounting blocks 6 to move, so that the installation box 2 can be pushed into the inner cavity of the shaft 1 but cannot be pulled out. The mounting blocks 6 are engaged in the inner cavity of the mounting groove 5. The unlocking mechanism is set inside the installation box 2. The unlocking mechanism is used to unlock the engagement between the mounting blocks 6 and the mounting groove 5. In specific use: by utilizing the design of multiple trapezoidal mounting blocks 6, the worker can push the installation box 2 into the installation position of the shaft 1 but cannot back out, which greatly simplifies the installation process. In addition, the horizontal installation method prevents the installation box 2 from becoming unstable due to vertical impact force during the operation of the buffer 3, reducing the worker's maintenance costs.

[0023] On one hand, a sliding plate 7 is slidably connected to the inner cavity of the mounting box 2. The sliding plate 7 is used to connect multiple mounting blocks 6. A circular rod 9 is slidably connected to the outer wall of the sliding plate 7. The mounting block 6 is fixedly connected to the end of the circular rod 9 away from the sliding plate 7. A first spring 10 is fixedly connected between the mounting block 6 and the sliding plate 7. In specific use: when the worker installs the mounting box 2, he pushes the mounting box 2 into the inner cavity of the shaft 1. During the movement of the mounting box 2, the mounting block 6 is squeezed by the inner cavity of the shaft 1 and the mounting groove 5 and moves towards the sliding plate 7, squeezing the first spring 10. When the mounting plate 6 moves to the next mounting groove 5, the first spring 10 resets and the mounting block 6 engages with the mounting groove 5 until the mounting box 2 is completely moved into the inner cavity of the shaft 1, completing the installation of the buffer 3.

[0024] On the other hand, the unlocking mechanism includes an adjusting block 8, which is slidably connected to the inner cavity of the mounting box 2. A threaded rod 12 is rotatably connected to the inner cavity of the mounting box 2. The adjusting block 8 is threaded onto the outer wall of the threaded rod 12. The adjusting block 8 is in contact with the sliding plate 7. The outer walls of the sliding plate 7 and the adjusting block 8 are set as inclined surfaces. The movement of the adjusting block 8 drives the two sliding plates 7 to move closer to or further away from each other. There are two sliding plates 7 arranged horizontally and symmetrically. A second spring 11 is fixedly connected between the two sliding plates 7. When the adjusting block 8 moves to unlock the mounting block 6, the second spring 11... The sliding plate 7 is always in contact with the adjusting block 8. In actual use: the worker rotates the threaded rod 12, which drives the adjusting block 8 to move. The adjusting block 8 can only move horizontally under the limit of the mounting box 2. When the adjusting block 8 moves forward, it squeezes the two sliding plates 7 to move away from each other. The sliding plates 7 drive the mounting block 6 to move to the working position. When the adjusting block 8 moves in the opposite direction through the threaded rod 12, the second spring 11 pulls the two sliding plates 7 to move closer to each other. The sliding plates 7 drive the mounting block 6 to move out of the mounting groove 5, thus unlocking the mounting block 6.

[0025] In addition, a limiting mechanism is provided on the outside of the threaded rod 12. The limiting mechanism includes a fixed plate 13. A turntable 4 is fixedly connected to the end of the threaded rod 12 away from the mounting box 2. The outer wall of the fixed plate 13 is fixedly connected to the outer wall of the mounting box 2. The fixed plate 13 is rotatably set outside the threaded rod 12. A limiting groove 14 is opened on the outer wall of the fixed plate 13. There are multiple limiting grooves 14, which are circumferentially spaced. A limiting block 15 is engaged with the inner wall of one of the limiting grooves 14. A pull rod 16 is slidably connected to the inner wall of the turntable 4. An elastic element 17 is fixedly set between the limiting block 15 and the pull rod 16. In actual use: the worker pulls the pull rod 16, and the pull rod 16 pulls the limiting block 15 through the elastic element 17 to move the inner wall of the limiting groove 14, and rotates the turntable 4, which drives the threaded rod 12 to rotate.

[0026] In specific operation: When the worker installs the installation box 2, the installation box 2 is pushed into the inner cavity of the shaft 1. During the movement of the installation box 2, the installation block 6 is squeezed by the inner cavity of the shaft 1 and the installation groove 5 and moves towards the sliding plate 7, squeezing the first spring 10. When the installation block 6 moves to the next installation groove 5, the first spring 10 returns to its original position and the installation block 6 is engaged with the installation groove 5 until the installation box 2 is completely moved into the inner cavity of the shaft 1, completing the installation of the buffer 3. When the installation box 2 needs to be disassembled, the worker pulls the pull rod 16. The pull rod 16 pulls the limit block 15 through the elastic element 17 to move the inner wall of the limit groove 14, rotates the turntable 4, and drives the threaded rod 12 to rotate. The threaded rod 12 drives the adjusting block 8 to move. The second spring 11 pulls the two sliding plates 7 to move closer to each other. The sliding plates 7 drive the installation block 6 to move out of the installation groove 5, completing the unlocking of the installation block 6.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
