The deeper the pipe is inserted, the larger the force area becomes, and the greater the resistance problem. The operation process is extremely laborious, not only increasing the labor intensity of construction personnel, but also greatly reducing the construction efficiency. SUMMARY

[0005] (I) Technical problem solved

[0006] In view of the shortcomings of the prior art, the utility model provides a socket type PE water supply pipe connecting structure to solve the problem of inconvenient connection of traditional pipe materials.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a socket type PE water supply pipe connecting structure, comprising pipes connected with each other, wherein one end of one of the pipes is provided with a sleeve, and the other end of the other pipe is inserted into the sleeve. A locking groove is formed on the inner wall of the sleeve. A positioning shaft matched with the locking groove is fixedly arranged on the outer wall of the other pipe end. When the two pipes are connected, the positioning shaft enters the locking groove, and the two pipes are connected and locked.

[0009] Further, the locking groove has an insertion part and a blocking part connected with each other. The insertion part is parallel to the axis direction of the sleeve along the inner wall of the sleeve. The blocking part is along the circumferential direction of the inner wall of the sleeve.

[0010] Further, an inclined part is arranged between the insertion part and the blocking part, and the inclined part is used for transitioning the positioning shaft.

[0011] Further, the outer wall of the pipe inserted in the sleeve is provided with an outwardly protruding flange body.

[0012] Further, the flange body is provided with a sealing ring close to one side of the sleeve.

[0013] Further, the outer wall of the pipe is fixedly provided with a screwing part.

[0014] (Three) beneficial effects

[0015] Compared with the prior art, the utility model provides a connecting structure of socket and spigot type PE water supply pipe, has the following beneficial effects:

[0016] The connecting structure of socket and spigot type PE water supply pipe, through the setting of positioning shaft and locking groove, positioning shaft is accurately inserted into locking groove and is further fastened through rotation, forms the close connecting structure, realizes pipeline connection through rotation, compared with traditional pipeline insertion, the deeper, the greater the stress area, the greater the problem of resistance, utilize the mode of rotation to replace the traditional direct insertion mode, significantly reduce the human consumption in the installation process, greatly alleviate the labor intensity of construction personnel, make pipeline installation work more relaxed, improve the installation efficiency.
