[0018] Referring to Figures 1-4 As shown, this application provides a mini hand chain hoist, which includes a hand chain hoist body 1. A transmission assembly 2 is arranged inside the hand chain hoist body 1. A transmission chain 3 is arranged on the transmission assembly 2. The transmission chain 3 is meshed and connected with the transmission assembly 2. A lubrication assembly 4 is arranged on one side of the transmission chain 3 inside the hand chain hoist body 1. The lubrication assembly 4 abuts against the transmission chain 3 to lubricate the transmission chain 3. A disassembly assembly 5 is arranged on the transmission chain 3 to facilitate the replacement of the transmission chain 3.
[0019] To further optimize the above technical solution, the lubrication assembly 4 includes a fixed frame 41. A rotating shaft 42 is arranged inside the fixed frame 41. The two ends of the rotating shaft 42 are respectively rotatably connected to the opposite side walls inside the fixed frame 41. Graphite balls 43 are arranged on the rotating shaft 42. The graphite balls 43 are fixedly connected to the rotating shaft 42. The graphite balls 43 abut against the transmission chain 3.
[0020] Specifically, the graphite balls 43 and the rotating shaft 42 can be disassembled together. When the graphite balls 43 need to be replaced after being used for a period of time, the graphite balls 43 and the rotating shaft 42 can be disassembled to replace the graphite balls 43.
[0021] To further optimize the above technical solution, the disassembly assembly 5 includes a connection block 51 and a connection groove 52. Part of the chain links of the transmission chain 3 are designed in a two-segment separated manner. A connection groove 52 is arranged on one section, and a connection block 51 is arranged correspondingly on the other section opposite to the connection groove 52. The connection block 51 is arranged in the connection groove 52. Threaded holes 53 are arranged at the corresponding positions of the connection block 51 and the connection groove 52. The connection block 51 and the other section of the chain link are connected by a screw 54.
[0022] To further optimize the above technical solution, a plurality of two-end separated chain links are provided, and the drive chain 3 is set to be separable into multiple segments, facilitating the replacement of the corresponding damaged chain in the later stage.
[0023] To further optimize the above technical solution, a plurality of lubricating assemblies 4 are provided, and the plurality of lubricating assemblies 4 are respectively arranged on both sides of the drive chain 3 to lubricate the drive chain 3.
[0024] During use, when pulling the drive chain 3, both sides of the chain will come into contact with the graphite balls 43 of the lubricating assembly 4, and the graphite balls 43 will apply graphite to the drive chain 3, playing a lubricating role for the drive chain 3. Lubrication of the drive chain 3 can be achieved every time of lifting or lowering, greatly reducing the probability of the chain getting stuck. Moreover, disassembly assemblies 5 are respectively arranged on different chain links of the chain, and the damaged section of the chain can be easily disassembled. Just screw out the screw rod 54 from the threaded hole 53 to separate the connecting block 51 from the connecting groove 52, and the separation of the chain link can be achieved. When replacing with a new chain, place the connecting block 51 in the connecting groove 52 and screw the screw rod 54 into the threaded hole 53 to achieve the connection of the chain link. The disassembly and connection method is very convenient, and the replacement of a rusty chain or a damaged chain can be easily realized.
[0025] Therefore, the present utility model adopts a mini hand chain hoist with the above structure, which is provided with lubricating assemblies arranged on both sides of the drive chain and in contact with the drive chain, capable of ensuring that the drive chain is not prone to jamming. At the same time, under the lubricating action of the graphite balls, the chain is not prone to rusting, extending the service life of the hand chain, avoiding the breakage of the hand chain caused by rust. The chain is provided with disassembly assemblies. When part of the chain rusts or is damaged otherwise, the corresponding chain can be removed for replacement, so as to quickly replace the guide chain and improve the maintenance efficiency.
