A first damper 9 is mounted on the bottom of the mounting plate 20, and a first buffer spring 10 is mounted on the first damper 9. A first buffer base plate 8 is mounted on the bottom of the first damper 9. A mounting plate 15 is mounted on the bottom of the slide rod 5, and a second threaded rod 21 is mounted on the slide rod 5. A second threaded groove that cooperates with the second threaded rod 21 is opened on the second threaded rod 21. The mounting plate 15... A second damper 13 is installed at the bottom of the buffer box 1, and a second buffer spring 14 is installed on the second damper 13. A second buffer base plate 12 is installed at one end of the second buffer spring 14, and a first threaded rod 16 is installed at the bottom of the second buffer base plate 12. A first threaded groove is opened on the buffer box 1 to cooperate with the first threaded rod 16. By setting the insert 24 to engage with the slot, the insert 24 can be pulled out of the slot by pulling the mounting plate 20, which can facilitate the disassembly and replacement of the first buffer spring 10, the first damper 9 and the first buffer base plate 8. By setting the second threaded rod 21 to rotate and connect with the second threaded groove, it can facilitate the rotation of the slide bar 5 to separate from the mounting plate 15. By setting the first threaded rod 16 to rotate and connect with the first threaded groove, it can facilitate the rotation of the second damper 13 and the second buffer spring 14 for disassembly and replacement.

[0027] In this embodiment, as Figures 1-6 As shown in the figure, the working process of a safety elevator car buffer base provided in this embodiment is as follows:

[0028] Step 1: The car presses down on the top plate 6, and the slide bar 5 slides on the buffer box 1, causing the first buffer bottom plate 8 to descend. The first buffer spring 10 and the first damper 9 work together to buffer the car.

[0029] Step 2: The car presses against the top plate 6, the slide bar 5 slides on the buffer box 1, the slide bar 5 presses against the mounting plate 15, and the second buffer spring 14 and the second damper 13 cooperate to buffer the car.

[0030] Step 3: Rotate slide bar 5, the second threaded rod 21 rotates in the second threaded groove to disassemble the top plate 6 and slide bar 5. Rotate the second buffer bottom plate 12, the first threaded rod 16 rotates in the first threaded groove to disassemble and replace the second damper 13 and the second buffer spring 14.

[0031] Step 4: Slide the limiting plate 17, slide the guide ring 11 on the guide rod 7, pull the mounting block 25 out of the mounting groove, pull the mounting plate 20, pull the insert block 24 out of the slot for disassembly and replacement of the second damper 13 and the second buffer spring 14.

[0032] In summary, in this embodiment, the safety elevator car buffer base, by setting the insert 24 to engage with the slot, allows the mounting plate 20 to be pulled to remove the insert 24 from the slot, facilitating the disassembly and replacement of the first buffer spring 10, the first damper 9, and the first buffer base plate 8. The second threaded rod 21, rotatably connected to the second threaded groove, facilitates the separation of the sliding rod 5 from the mounting plate 15. The first threaded rod 16, rotatably connected to the first threaded groove, facilitates the rotational disassembly and replacement of the second damper 13 and the second buffer spring 14. The buffer box 1 and the box door 2, working in tandem, facilitate the operation of the second buffer spring 14. 4. For protection, the hinge 3 allows the box door 2 to be rotated to open the buffer box 1. The guide ring 11 is slidably connected to the guide rod 7 to guide and limit the position plate 17. The insert block 24 is inserted into the slot, the position plate 17 is slid, and the guide ring 11 slides on the guide rod 7. The mounting block 25 is inserted into the mounting groove to limit the first buffer spring 10 after installation. The main magnet 22 and the auxiliary magnet 23 cooperate to limit the installed insert block 24. The pull rod 18 makes it easy to pull the position plate 17. The anti-slip pad increases the friction of the pull rod 18.
