Technical Field

[0001] The utility model relates to the technical field of heat preservation covers, in particular to a pipeline heat preservation cover. Background Technique

[0002] During the installation of pipelines, the outer side of the pipeline is equipped with a heat preservation layer by default. However, the heat preservation effect at the joints of the pipelines is poor, and additional heat preservation covers need to be added to insulate the joints of the pipelines. According to a pipeline heat preservation cover proposed in the patent authorization publication number: CN221054561U, this utility model relates to the technical field of pipeline heat preservation. This pipeline heat preservation cover solves the problem that when encountering cold weather, the liquid inside the pipeline is extremely likely to freeze, thus affecting the liquid transportation of the pipeline. Usually, in order to avoid the internal freezing of the pipeline, sponges, etc. are used for wrapping. However, when encountering extremely cold weather, the pipeline will still freeze.

[0003] However, during the installation of the existing heat preservation covers, bolts and clamps are required to tie the heat preservation layer to the outer side of the pipeline, resulting in the inability to tightly tie the splicing parts, affecting the heat preservation performance, and the installation method of the bolts is relatively cumbersome, affecting the installation efficiency. Therefore, the existing technology needs to be improved. Content of the Utility Model

The limiting frame can limit the second half-ring through the fixed plate.

[0008] Preferably, one end of the first spring is fixedly connected to the moving frame, and the other end of the first spring is fixedly connected to the fixed plate. The first spring can drive the moving frame to automatically reset through its elastic force.

[0009] Preferably, the auxiliary mechanism includes a fixed frame. Fixed frames are fixedly connected to the outer sides of both the first half-ring and the second half-ring. A clamping frame is slidably connected to the outer sides of both the first half-ring and the second half-ring. A second spring is arranged on the outer side of the rod of the fixed frame.
