[0007] (II) Technical solution

[0008] To achieve the above purpose, the utility model is implemented by the following technical solutions:

[0009] A quick-mounting type gas leakage plugging mechanism based on natural gas pipeline, comprising a shell, two ends of the shell are provided with fixing mechanisms, each fixing mechanism comprises a mounting plate, a spring, a limiting block, a hole and a limiting plate, the mounting plate is arranged outside the shell, two springs are fixedly connected outside the mounting plate, the limiting block is slidingly connected outside the mounting plate, the hole is formed in the mounting plate, and the limiting plate is fixedly connected at one end outside the two springs and slidingly connected at the other end inside the hole.

[0010] Each mounting plate has a support shaft fixedly mounted on its exterior, with a spring movably sleeved on the exterior of the support shaft. Each limiting plate has round holes at both ends, through which the limiting plate is slidably connected to the exterior of the support shaft. Each mounting plate has a connecting plate fixedly mounted on its exterior, with a through hole on the exterior of the limiting block, through which the limiting block is slidably connected to the exterior of the connecting plate. Each housing has a movable plate fixedly mounted on its exterior, with a movable groove on the exterior of each mounting plate, through which the mounting plate is slidably connected to the exterior of the movable plate.

[0012] Preferably, each mounting plate has a groove on its exterior, and the rotating shaft is rotatably connected inside the groove.

[0013] (III) Beneficial Effects

[0014] 1. By setting a limiting plate and cooperating with a spring, when sealing leaks, the two housings are placed together and fitted onto the outside of the pipe. Then, the limiting block is pulled upwards so that it is no longer attached to the surface of the limiting plate. Under the action of the spring, the limiting plate automatically fits onto the outside of the lower housing through the opening. At this point, the two housings are fixed together. The operator can then use bolts to quickly connect and reinforce the two housings. In this process, the operator does not need to hold the two housings and fit them onto the outside of the pipe, reducing the probability of errors during operation, improving installation efficiency, and thus achieving rapid installation of the leak sealing mechanism.

[0015] 2. By setting a handle and matching the groove, before the housing is installed in front of the pipe, turn the handle to make the handle turn out of the groove. Then pull the handle to drive the limiting plate to move. At this time, the limiting block slides down. Then release the handle. At this time, the limiting plate is restricted by the limiting block and cannot move, so that the two housings can fit together and avoid the limiting plate affecting the installation of the housing.
