[0002] A hoisting chain is a connecting piece used in the hoisting, running and other links of a hoisting machine. It is composed of chain links and pins, usually made of steel materials, and can be a circular ring or a flat rectangular metal structure. It has the characteristics of being wear-resistant, high-temperature resistant, low ductility, and not elongating after being stressed. Hoisting chains are classified according to material, structure and working grade. Common ones include alloy steel chain groups, stainless steel chain groups and synthetic fiber chain groups, etc.
[0003] At present, the following problems exist in the hoisting chains on the market during actual use:
[0004] 1. When traditional hoisting chains are used to hoist items at different heights, the lengths of the required chain groups are different. If there is a lot of remaining chain group, it may lead to a very long chain group, requiring the hoisting machine to have a high hoisting height, which is inconvenient to use to a large extent;
[0005] 2. When traditional hoisting chains are used, when they are used frequently or hoist heavy goods, they may break due to insufficient strength, posing a great safety hazard, and the safety protection of this hoisting chain is relatively poor. Content of the Utility Model
[0006] The purpose of the utility model is to provide a hoisting chain with a locking structure to solve the technical problems raised in the background technique.
[0007] To achieve the above purpose, the specific technical solution of the utility model is as follows: A hoisting chain with a locking structure includes a locking housing and a chain group. Preferably, a turntable is fixedly connected to the inner side of the locking housing, the chain group is installed on the surface of the turntable, a first threaded sleeve is fixedly connected to the surface of the locking housing, a second hand-tightening bolt is connected to the inside of the first threaded sleeve through threads, a pressing plate is fixedly connected to the surface of the second hand-tightening bolt, a first fixing plate is fixedly connected to the top of the locking housing, a first hand-tightening bolt is connected to the surface of the first fixing plate through threads, the surface of the first hand-tightening bolt penetrates the chain group, the surface of the first hand-tightening bolt is connected to a second fixing plate through a bolt, and the bottom of the second fixing plate is fixedly connected to the locking housing.
