[0025] Please refer to Figures 1-3 , a pipe joint protection mechanism for municipal gas transmission, including a pipe body 1, a connecting member 2, and a reinforcement component. There are two pipe bodies 1 and two connecting members, and the two connecting members 2 are respectively installed at one end of the two pipe bodies 1 close to each other. A reinforcement component is arranged outside one end of the two pipe bodies 1 close to each other;

[0026] The reinforcement component includes a fixing ring 3, an adjusting plate 4, and a resisting block 7. There are two groups of fixing rings 3, and two in each group are installed up and down outside the pipe body 1. An adjusting plate 4 and a resisting block 7 are installed inside each fixing ring 3. The bottom of the adjusting plate 4 is welded to the resisting block 7, and one end of a threaded rod is installed at the top of the adjusting plate 4. The threaded rod is threadedly connected to the fixing ring 3.

[0027] In this embodiment, the two connecting members 2 are respectively bolt-fixed to the ends of the two pipe bodies 1, and the two connecting members 2 are bolt-fixed to each other.

[0028] It should be noted that this design not only ensures the direct connection strength between the pipe bodies 1, but also forms a stable frame structure through the interlocking bolt connection between the connecting members 2, enhancing the structural stability of the entire pipe joint and preventing the separation or dislocation of the pipe bodies caused by external forces.

[0029] In this embodiment, after two fixing rings 3 in each group are distributed vertically and abut against the pipe body 1, the two fixing rings 3 are fixed by bolts. After the ends of the two groups of fixing rings 3 that are close to each other abut against the bottoms of the two connecting pieces 2, they are fixed by bolts.

[0030] It should be noted that this double reinforcement mechanism not only enhances the external support force of the pipe body 1, but also forms a continuous support system through the close combination of the fixing ring 3 and the connecting piece 2, effectively dispersing the external force load that the pipeline system may receive, and improving the bearing capacity and durability of the overall structure.

[0031] In this embodiment, T-shaped sliders 5 are welded to both ends of the adjusting plate 4, and sliding grooves 6 are formed in the inner wall of the fixing ring 3 and are slidably connected to the T-shaped sliders 5.

[0032] It should be noted that the design of the T-shaped slider 5 and the sliding groove 6 allows the adjusting plate 4 to move smoothly vertically inside the fixing ring 3 without deviation or rotation, ensuring the accuracy and stability of the adjustment process.

[0033] In this embodiment, the outer part of the threaded rod near the bottom end is not provided with threads, and a bearing is fixedly installed. A hole is formed in the top of the adjusting plate 4, and the threaded rod is rotatably connected to the hole through the bearing.

[0034] It should be noted that this design enables the threaded rod to smoothly drive the adjusting plate 4 to move up and down when rotating

[0035] In this embodiment, the abutting block 7 is arc-shaped and abuts against the outside of the pipe body 1. The top of the threaded rod passes through the fixing ring 3 and is welded with a rotating part 8.

[0036] It should be noted that the arc-shaped design enables the abutting block 7 to better fit the contour of the pipe body 1, increasing the contact area and support strength, thereby improving the protection effect on the pipe body.

[0037] Beneficial effects:

[0038] For the pipe joint protection mechanism for municipal gas transmission, the double bolt fixation of the connecting piece 2 ensures the tight connection between the pipe bodies 1, effectively preventing the gas leakage problem caused by loose connection. Then, by distributing two groups of fixing rings 3 vertically and fixing them to the outside of the pipe body 1 by bolts, not only the overall stiffness of the pipe body is enhanced, but also the pipe body is additionally supported by the abutting block 7, further improving the ability to resist external force impact. The combined design of the adjusting plate 4 and the threaded rod enables users to easily adjust the pressing degree of the abutting block 7 on the pipe body according to actual situations, ensuring both sealing performance and facilitating installation and maintenance.

[0039] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
