By using the combination of the threaded rod, the threaded hole and the bearing, it is convenient to push the pressure plate and the upper clamping block to move downward, so as to achieve the purpose of reinforcing the gas pipeline, thereby improving the use effect of the gas pipeline fixing device.

[0003] Existing fixtures cannot adjust the height, and the height of general fixtures is fixed. During use, due to the uneven construction length, the installation of the natural gas pipeline needs to ensure that the pipeline is level, which requires fixtures of different heights. Generally, if the height difference is large, the fixture needs to be remade, and if the height difference is small, it is necessary to use pads to raise the fixture, which is more troublesome and reduces practicality and applicability. It is also not convenient to install and disassemble pipelines. Generally, the fixing devices use screws to press and fix the pipelines. When installing and disassembling the pipelines, it is necessary to repeatedly turn the bolts to disassemble and assemble them. The disassembly and assembly process is more cumbersome, which increases the workload and reduces work efficiency. In order to solve the above-mentioned problems, we propose a fixing device for natural gas pipeline construction. Utility Model Content
