[0002] A gas pipeline is a special pipeline for transporting combustible gas. It is a metal gas pipeline, which can solve the defects of easy falling off, easy aging, easy insect bite and short service life of a rubber tube. When fixing a gas pipeline at present, generally a smaller clamp is used for fixing, and only has a fixing effect. When the gas pipeline is transporting, it will vibrate, and the smaller clamp cannot protect the gas pipeline, which has limitations. Therefore, we have designed a gas pipeline fixing device which can fix and protect. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] In order to make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0014] A gas pipeline fixing device convenient for installation, such as Figure 1 ,2 As shown in FIGS. 3 and 4, it includes several tubular clamps. An expansion bolt 1 is detachably installed on one of the clamps. Each clamp includes two semi-circular tubes 2. The two semi-circular tubes 2 are spliced into a circular tube. A dovetail slider 3 and a dovetail chute 4 are respectively and fixedly installed on the semi-circular tubes 2. The dovetail slider 3 on one semi-circular tube 2 is slidably connected to the dovetail chute 4 on the corresponding semi-circular tube 2. Semi-circular threaded grooves 5 are respectively opened at one end of the semi-circular tubes 2. The threaded grooves 5 are coaxially arranged with the corresponding semi-circular tubes 2. The two threaded grooves 5 form a threaded groove. Semi-external threaded tubes 6 are respectively and fixedly installed at the other end of the semi-circular tubes 2. The semi-external threaded tubes 6 are coaxially arranged with the corresponding semi-circular tubes 2. The two semi-external threaded tubes 6 form an external threaded tube. The external threaded tube on the circular tube can be threadedly engaged and connected with the threaded groove on another circular tube. The structure of the utility model is simple and ingenious. It can connect several tubular clamps through threads to form a long protective tube, which can not only fix the gas pipeline 100, but also protect the gas pipeline 100, reduce the possibility of pipeline damage, meet the actual needs, and is suitable for popularization. When using the utility model, the two semi-circular tubes 2 are respectively placed coaxially with the gas pipeline 100, and then the two semi-circular tubes 2 are slid relative to each other, and the dovetail slider 3 is slid into the corresponding dovetail chute 4 until the corresponding end faces of the two semi-circular tubes 2 are flush. At this time, the two semi-circular tubes 2 form a circular tube and are sleeved on the gas pipeline 100. Then, other pairs of semi-circular tubes 2 are formed into circular tubes sleeved on the gas pipeline 100. Then, the external threaded tube formed by the semi-external threaded tubes 6 is threadedly engaged and connected with the threaded groove on the adjacent circular tube, so as to form a long protective tube to protect the gas pipeline 100. Then, the expansion bolt 1 is installed on the wall, and one of the circular tubes is installed on the expansion bolt 1, and the installation is completed.

[0015] Specifically, as shown in the figure, semi-threaded columns 20 are respectively and fixedly installed on the two semi-circular tubes 2 of one of the clamps in this embodiment. The two semi-threaded columns 20 form a threaded column. A cylinder 21 with internal threads is threadedly engaged and connected to the threaded column. A coaxial through hole is opened at the closed end of the cylinder 21, and a coaxial slide bar 22 is slidably installed. A baffle 23 is fixedly installed at one end of the slide bar 22 located inside the cylinder 21. The outer diameter of the baffle 23 is larger than the diameter of the through hole. The slide bar 22 is fixedly installed on the expansion bolt 1. After the expansion bolt 1 is fixed to the wall, the threaded column formed by the two semi-threaded columns 20 is aligned with the cylinder 21, and then the cylinder 21 is rotated and screwed onto the threaded column until one end of the threaded column abuts against the baffle 23, and the circular tube is installed on the expansion bolt 1; when disassembling, the cylinder 21 is screwed in the reverse direction until it is no longer threadedly engaged and connected with the threaded column.

[0016] Specifically, as shown in the figure, several strip-shaped rubber strips 30 are fixedly installed on one side of the semi-circular pipe 2 facing the gas pipeline 100. After the circular pipe formed by splicing two semi-circular pipes 2 is sleeved on the gas pipeline 100, the rubber strips 30 are in contact with the outer circumference of the gas pipeline 100. When the gas pipeline 100 vibrates, it can avoid friction with the inner wall of the circular pipe, reduce the wear on the gas pipeline 100, improve safety, and at the same time, the elasticity of the rubber strips 30 can provide buffering when the gas pipeline 100 vibrates.

[0017] Furthermore, as shown in the figure, avoidance grooves 40 are respectively formed on the semi-external thread pipes 6 of this embodiment. When the dovetail slider 3 is installed in the dovetail chute 4, the arrangement of the avoidance grooves 40 prevents the semi-external thread pipes 6 from interfering with the dovetail slider 3.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
