[0027] In order to better understand the purpose, structure and function of the present invention, the chain structure for a hoist of the present invention is further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-4 As shown, a chain structure for an elevator of the present invention includes an outer chain plate 2, a fixed plate 1 is installed on the outside of the outer chain plate 2, a through-hole 14 is provided on the outside of the fixed plate 1, a fixed rod 10 is passed through the through-hole 14, the end of the fixed plate 1 is fixedly connected to the fixed block 8, the surface of the fixed block 8 is fixedly connected to the spring 9, and the other end of the spring 9 is fixedly connected to the fixed plate 1, a handle 3 is installed on the outside of the fixed block 8, the top end of the fixed rod 10 is inserted into the fixed hole 6, and the fixed hole 6 is provided on the outside of the bucket 4. In this way, when repairing or installing the elevator bucket 4, the handle 3 can be held and pulled outward to move the fixed rod 10 away from the fixed hole 6, so that the bucket 4 can be removed. Later, when installing, the fixing hole 6 is aligned with the fixed rod 10, and after pulling the handle 3, the fixing plate 1 is used as the external spring 9 to use the rebound force of the fixed rod 10 to insert the fixed hole 6 into the fixed hole 6 and fix the bucket 4. In this way, when installing or disassembling the elevator bucket 4, it is very convenient and saves time and effort.

[0029] The fixed plate 1 is inserted into the socket 16, and the socket 16 is opened on the outside of the baffle 7. A damping slider 17 is installed at the bottom of the baffle 7, and the damping slider 17 is inserted into the chute 20. The chute 20 is opened at the top of the extension plate 18. In this way, when material falls, the baffle 7 outside the fixed plate 1 can be used to block the top of the chain, so that the material is not easy to fall on the chain, and the damping slider 17 and the chute 20 can be used to pull the extension plate 18 to increase the blocking range of the baffle 7, thereby improving the effect of the baffle 7 in blocking the chain. In this way, the fallen material is not easy to cause wear or jamming of the chain during operation, so that it does not affect the service life of the chain.

[0030] A threaded hole 15 is provided on the outside of the fixing plate 1, and a bolt 21 is threadedly connected to the inside of the threaded hole 15. The bolt 21 passes through the inside of the circular hole 19, and the circular hole 19 is provided on the outside of the baffle 7. The structure of the bolt 21 and the threaded hole 15 makes it convenient for the staff to fix the baffle 7 structure.

[0031] A shaft 11 is installed on the side of the outer link plate 2. The shaft 11 passes through the interior of the sleeve 12. The structure of the shaft 11 and the sleeve 12 allows the chain to operate effectively.

[0032] An inner link plate 13 is installed outside the sleeve 12. The inner link plate 13 is located on the side of the outer link plate 2. Through the structure of the inner link plate 13 and the outer link plate 2, the chain can operate effectively.

[0033] A handle 5 is installed outside the bucket 4, and there are two handles 5. The structure of the handle 5 makes it convenient for workers to lift the bucket 4.

[0034] The working principle of the chain structure for the hoist: When using the chain structure for the hoist, first, you can install the fixing plate 1 on the outside of the outer chain plate 2, and open a through hole 14 on the outside of the fixing plate 1, and pass the fixing rod 10 through the through hole 14. Then, fix the fixing block 8 at the end of the fixing plate 1, and fix the spring 9 on the surface of the fixing block 8, and the other end of the spring 9 is fixedly connected to the fixing plate 1. Then, install the handle 3 on the outside of the fixing block 8, and insert the top of the fixing rod 10 into the fixing hole 6, and open the fixing hole 6 on the outside of the bucket 4. In this way, when repairing or installing the bucket 4 of the elevator, you can hold the handle 3 and pull it outward to move the fixing rod 10 away from the fixing hole 6, so that the bucket 4 can be removed. Later, when installing, align the fixing hole 6 with the fixing rod 10, pull the handle 3, and use the fixing plate 1 to return the external spring 9. Elastic force, insert the fixing rod 10 into the fixing hole 6 and fix the bucket 4, so it is very convenient and time-saving and labor-saving when installing or disassembling the bucket 4 of the elevator. Secondly, it can be inserted into the socket 16 of the fixing plate 1, and the socket 16 is opened on the outside of the baffle 7. Then, the damping slider 17 is installed at the bottom of the baffle 7, and then the damping slider 17 is inserted into the chute 20, and the chute 20 is opened on the top of the extension plate 18. In this way, when material falls, the baffle 7 outside the fixing plate 1 can be used to block the top of the chain, so that the material is not easy to fall on the chain, and the damping slider 17 and the chute 20 can be used to pull the extension plate 18 to increase the blocking range of the baffle 7, thereby improving the effect of the baffle 7 in blocking the chain, so that the fallen material is not easy to cause wear or jamming of the chain during operation, so that it does not affect the service life of the chain.
