Description

Technical Field

[0001] The utility model relates to the technical field of spanner equipment, in particular to a chain spanner device. Background Art

[0002] During construction, a large number of components need to be rotated and tightened. In order to meet the standardization and regularization of construction, components of different diameters usually need to be quickly rotated and tightened. In the prior art, at the construction site, a simple wrench device suitable for the rotation and tightening of components such as bolts and the like and which is flexible and easy to operate is rare. The existing tightening devices are not simple and flexible enough and cannot be used for the rotation and tightening of components of different diameters, thereby increasing costs and inconvenience in construction. The handle length is fixed, which causes certain inconveniences when used. At the same time, the resistance block causes wear due to long-term use and cannot be replaced.

[0003] For example, a chain-type pipe wrench disclosed in the authorized patent document with application number CN202222529018.3 belongs to the field of construction technology. The wrench includes a handle, the head end of the handle is hingedly connected with a chain, and the handle is fixed with an anti-skid connecting piece, a guide cylinder and a bolt positioning column in sequence from the head end to the back, and the free end of the chain passes through the guide cylinder and is connected and fixed with the bolt positioning column. The utility model wrench has low cost, flexible operation, and strong on-site practicality. When the pipeline is threadedly connected, the tightness can be adjusted by the length of the positioned chain to complete the threaded connection of the pipeline; the utility model wrench can be used for pipelines of various specifications and models, and the length of the chain can also be adjusted, which is convenient for operators to use; the utility model wrench is mainly tightened by the chain, anti-skid connecting piece, guide cylinder and bolt positioning column, and the wrench is more reliable to use, ensuring that the wrench will not be disengaged during use, causing slippage.

[0004] The above patent has the problem that the fastening device is not simple and flexible enough and cannot be applied to the rotational fastening of components of different diameters, which results in increased costs and inconvenience in construction. The handle length is fixed, which causes certain inconveniences when used. Therefore, we need to provide a chain wrench device. Utility Model Content

[0005] The utility model aims to provide a chain wrench device, which is implemented by putting a chain body on a component to be rotated, and rotating a fixing nut to drive a long rod to rotate. The long rod rotates on the adjusting nut, thereby controlling the movement of the long rod to resist the mechanism. The mounting seat on the fixed disk at one end of the long rod fits with the component to be rotated and tightened. When the long rod is rotated, the rotation and tightening of the component can be achieved. On the contrary, the front end of the long rod will be away from the component to be rotated and tightened, so that the chain body stuck on the component to be rotated and tightened can be loosened. The material can be fully and reasonably utilized on site according to actual construction needs and the device can be made on demand at any time. The mounting seat can be separated from the threaded groove by a limit bolt, and the mounting seat can be replaced. The convex block with rubber on the mounting seat can fit with the component to be rotated and tightened to enhance friction, thereby solving the problems raised in the above-mentioned background technology.

The mounting seat 62 on the fixed disk 61 at one end of the long rod 1 fits with the component to be rotated and tightened. When the long rod 1 is rotated, the rotation and tightening of the component can be achieved. Conversely, the front end of the long rod 1 will be away from the component to be rotated and tightened, so that the chain body 5 stuck on the component to be rotated and tightened is loosened.
