DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] Embodiment: A kind of construction is used to prevent falling safety device, such as Figures 1-4As shown, the assembly includes a housing 1, a ratchet 2, a locking element 3, a wire rope 4, and a lifting ring 5. Both housings 1 have through grooves 6 on their surfaces. A closing piece 7 is rotatably connected to the inner side of the through groove 6. A drive shaft 8 is rotatably mounted inside the housing 1. The locking element 3 is positioned outside the drive shaft 8 for limiting and fitting. A thread 9 is provided on the outer periphery of the drive shaft 8, and a nut 10 is threaded onto the outer side of the drive shaft 8 through the thread 9. Notches 11 are provided on the inner side of the through groove 6 and at the edge of the closing piece 7. A magnetic element 12 is installed inside the notch 11. The closing piece 7... A pull ring 13 is installed on the side. A liquid storage sleeve 14 is installed at the bottom of the housing 1 and is fitted outside the steel wire rope 4. The liquid storage sleeve 14 has a liquid storage cavity 15 for storing lubricant. A coating cotton sleeve 16 is provided on the inner side of the liquid storage sleeve 14 and is fitted outside the steel wire rope 4. A through hole 17 is provided on the inner side of the liquid storage sleeve 14 and penetrates the liquid storage cavity 15. A cotton swab 18 is integrally formed on the outer side of the coating cotton sleeve 16 and penetrates the through hole 17. A filling hole 19 is provided on the outer periphery of the liquid storage sleeve 14 and a sealing plug 20 is provided inside the filling hole 19.

[0024] Furthermore, the closing piece 7 is located inside the through groove 6 in a flip-adjustable state. When the closing piece 7 flips and closes with the inside of the through groove 6, the closing piece 7 and the inside of the through groove 6 are magnetically fixed by the magnetic attractor 12.

[0025] Furthermore, after the nut 10 is rotated and removed from the outside of the drive shaft 8 via the thread 9, the clamp 3 is in a movable disassembly / removal state located outside the drive shaft 8.

[0026] Furthermore, when the wire rope 4 moves downward, the coating cotton sleeve 16 inside the liquid storage sleeve 14 absorbs and guides the lubricant inside the liquid storage cavity 15 through the cotton swab 18, and the coating cotton sleeve 16 coats the outside of the wire rope 4.

[0027] The working principle of this utility model:

[0028] The surface of the housing 1 has a through groove 6 that communicates with the interior of the housing 1. A closing piece 7 is rotatably connected to the inside of the through groove 6. When the closing piece 7 is closed with the inside of the through groove 6, the closing piece 7 and the inside of the through groove 6 can be magnetically attracted and fixed to each other by a magnetic attractor 12. When disassembling or assembling the clip 3, the closing piece 7 can be flipped and pulled out directly from the inside of the through groove 6 by using the pull ring 13. At this time, the nut 10 can be rotated to disassemble, and the clip 3 can be slid out and replaced. The installation is the same. In this way, the entire housing 1 can be reassembled. The card 3 can be quickly replaced without disassembling the body, which facilitates the quick disassembly and replacement of the card 3. The liquid storage sleeve 14 stores the lubricant inside the liquid storage cavity 15. The outside of the wire rope 4 is fitted with the coating cotton sleeve 16 inside the liquid storage sleeve 14. As the wire rope 4 moves, the coating cotton sleeve 16 can absorb and guide the lubricant inside the liquid storage cavity 15 through the cotton stick 18, so as to apply the lubricant to the outside of the wire rope 4 and avoid the wire rope 4 itself from being subjected to stress and wear.

[0029] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application.
