[0012] Figure 2 It is a structural schematic diagram of a pipe wall limiting rod assembly of the utility model.

[0013] In the figure:

[0014] 1. Joint; 2. Hole-opening machine connection part; 3. Retraction groove; 4. Plug connection part; 5. Plug connection hole; 6. Pipe wall limit rod assembly; 61. Limit rod; 62. Connection seat; 63. Connecting rod; 64. Fixing pin. DETAILED DESCRIPTION

[0015] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1 As shown, a detachable joint for balanced short section plugging includes a joint 1, one end of the joint 1 is integrally provided with a hole opening machine connection part 2, the other end of the joint 1 is integrally provided with a plugging connection part 4, and pipe wall limit rod assemblies 6 are fixedly installed on the upper and lower sides of the joint 1.

[0016] In this embodiment, combined with the Figure 2 As shown, the tube wall limit rod assembly 6 includes a limit rod 61, on which mounting holes are sequentially opened, a connecting rod 63 is arranged on one side of the limit rod 61, a fixing pin 64 is installed between the upper end of the connecting rod 63 and the limit rod 61, and a connecting seat 62 is installed on the lower end of the limit rod 61 and the lower end of the connecting rod 63 by a pin shaft.

[0017] In this embodiment, specifically, a plugging connection hole 5 is opened inside the plugging connection portion 4 .

[0018] In this embodiment, specifically, a backstop groove 3 is provided between the joint 1 and the hole-opening machine connection portion 2 .

[0019] In this embodiment, specifically, the plurality of connection seats 62 are integrally arranged on the left and right sides of the upper and lower sides of the joint 1 .

[0020] How it works

[0021] In the utility model, after the hole punching machine connection part 2 is connected to the external hole punching machine, it is locked and fixed by a top screw, and the plug connection part 4 and the plug connection hole 5 are connected to the external plug. The hole punching machine drives the joint 1 to rotate forward or reversely to drive the plug to move, so as to facilitate the installation or removal of the plug. The user adjusts the connection position of the connecting rod 63 and the limiting rod 61 according to the pipe diameter of the pipeline. After the joint 1 enters the pipeline, the limiting rod 61 contacts the pipe wall, thereby positioning the position of the joint 1, which is convenient for the installation of the external hole punching machine and the hole punching machine connection part 2.

[0022] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
