[0028] An embodiment of the present utility model provides a pipe plug dedicated to a PE corrugated pipe, as Figures 1-6 shown, the pipe plug dedicated to a PE corrugated pipe includes:

[0029] A fixing member 200, the fixing member 200 is assembled on the PE corrugated pipe 100, the fixing member 200 includes a first sealing ring 210 and a fixing ring 220, and the fixing ring 220 is fixed in the corrugated groove of the PE corrugated pipe 100 by a clamping method;

[0030] A pipe plug body 300, the pipe plug body 300 includes an outer cover 310 and an inner plug 320, the inner plug 320 is arranged inside the outer cover 310, the outer cover 310 is nested on the outer wall of the PE corrugated pipe 100, and the inner plug 320 extends into the interior of the PE corrugated pipe 100;

[0031] The outer cover 310 is fixedly connected to the side of the fixing ring 220 by bolts, and the first sealing ring 210 abuts against the second sealing ring 330;

[0032] In this application, the pipe plug dedicated to PE corrugated pipes is designed in combination with the structure of PE corrugated pipes. A specially designed fixing member 200 is used to connect with the outer wall of the PE corrugated pipe to construct a fixing point on the outer wall of the PE corrugated pipe. When the pipe plug body 300 plugs the PE corrugated pipe 100, the fixing point provided by the fixing member 200 is utilized to improve the sealing and connection performance of the pipe plug body 300 to the PE corrugated pipe 100;

[0033] In this application, the structure of the fixing member 200 itself is composed of a first sealing ring 210 and a fixing ring 220. The fixing ring 220 serves as the main force-bearing component. The outer cover 310 is fixed to the ring side of the fixing ring 220 by bolts to enhance the connection between the pipe plug body 300 and the PE corrugated pipe 100 through the assembly structure. The first sealing ring 210 fills the gap during the connection process between the fixing member 200 and the pipe plug body 300. The deformation force generated during the assembly process compresses the first sealing ring 210 to fill the gap between the pipe plug body 300 and the fixing member 200, improving the sealing performance between the fixing member 200 and the pipe plug body 300. A sealing mechanism is formed again outside the inner plug 320 to further enhance the sealing effect of the pipe plug body 300;

[0034] As a preferred implementation manner in this embodiment, a sealing groove for accommodating the pipe is provided between the outer cover 310 and the inner plug 320, and a third sealing ring 350 is provided in the sealing groove; after the inner plug 320 is inserted into the PE corrugated pipe 100, the pipe wall of the PE corrugated pipe 100 will be inserted into the sealing groove, and the third sealing ring 350 will be in close contact with the end face of the PE corrugated pipe 100 to form a sealing effect;

[0036] A second sealing ring 330 is provided on the side of the outer cover 310 away from the inner plug 320. During the assembly process, the second sealing ring 330 is in contact connection with the first sealing ring 210 to form a sealing structure;

[0037] In this application, the outer wall of the inner plug 320 and the inner wall of the PE corrugated pipe 100 form a first-layer sealing structure, and the third sealing ring 350 provided in the sealing groove is in contact with the end face pipe wall of the PE corrugated pipe 100 to form a second-layer seal. During the assembly process of the outer cover 310 and the fixing member 200, a third-layer sealing structure is formed between the second sealing ring 330 and the first sealing ring 210. Under the action of the three-layer sealing structure, the sealing effect of the pipe plug body 300 on the PE corrugated pipe 100 is improved;

[0038] As a preferred implementation manner in this embodiment, the fixing ring 220 includes a ring body 221 and a joint 223; the structure of the fixing ring 220 is similar to that of a clamp in the prior art. The joint 223 is arranged at both ends of the ring body 221. To improve the sealing effect of the fixing ring 220, the arrangement position of the joint 223 is finely adjusted and arranged on the end face of the ring body 221 away from the first sealing ring 210. An installation groove is provided at the front end of the fixing ring 220, and the first sealing ring 210 is attached to the installation groove. The inner wall of the fixing member 200 is an arc structure, which is adapted to the corrugated grooves on the outer wall of the PE corrugated pipe 100. The corrugated grooves mainly provide an axial limiting function for the fixing member 200. A soft rubber layer is also provided on the inner wall of the fixing ring 220, and the soft rubber layer will be in close contact with the outer wall of the PE corrugated pipe 100 during the fastening process of the fixing ring 220;

[0039] It should be noted here that the overall outer diameter of the fixing member 200 and the inner diameter of the outer cover 310 are adapted, and the overall outer diameter of the fixing member 200 and the inner diameter of the outer cover 310 are larger than the maximum outer diameter of the PE corrugated pipe 100. The arrangement of the joint 223 on the end face will not affect the assembly of the fixing member 200, and the joint 223 is arranged close to the outer edge of the fixing ring 220;
