As a preferred technical scheme of the utility model, all be equipped with connecting portion, two butt joints on the relative both sides of mounting pass through screw fixed connection between the connecting portion on the mounting.

As an optimal technical scheme of the utility model, the laminating has the one deck elastic layer on the inside wall of mounting.

As an optimal technical scheme of the utility model, the ascending length of reinforcement is 1.6 ~ 1.85 times of welding part length on the horizontal direction.

As an optimal technical scheme of the utility model, weld part and PE pipe body are integrated into one piece structure.

The utility model has the advantages that:

the utility model has the advantages of reasonable design, wherein cover on PE pipe body and establish a plurality of metal sleeves can effectual improvement PE pipe body's compressive property, set up spacing groove on the metal sleeve simultaneously and can be used for fixing a position the slips on the welding machine when the welding, improve the convenience when the slips is installed, guarantee the relative stability between slips and PE pipe body when welding the extrusion simultaneously, improve the welding effect; and the welded fastening subassembly that sets up then can two PE pipe body weld joints's of effectual improvement stability, prolongs its life.

Detailed Description

The invention will now be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, a PE pipe convenient for welding includes a PE pipe body 1, a plurality of metal sleeves 2 fixedly sleeved outside the PE pipe body, and a welding fixing assembly, wherein welding portions 3 are respectively disposed at two opposite end portions of the PE pipe body 1, and specifically, the welding portions 3 and the PE pipe body 1 are of an integrally formed structure; the outer diameter of the welding part 3 is smaller than that of the PE pipe body 1, a plurality of limiting grooves 4 are uniformly distributed along the length direction of the metal sleeve 2 on the outer side wall of the metal sleeve 2, specifically, in the embodiment, the number of the limiting grooves 4 on each metal sleeve 2 is two, the limiting grooves 4 are arranged along the circumferential direction of the metal sleeve 1, and further, in the specific application process, the structure of each limiting groove 4 is matched with the structure of a slip on an external welding machine, so that the inner side of the slip on the external welding machine can be clamped in the limiting grooves 4 during welding;

furthermore, the welding and fixing assembly comprises two fixing pieces 5 which are symmetrically butted together, the fixing pieces 5 are also made of metal materials, and the fixing pieces 5 are in a semi-annular structure, so that the two fixing pieces 5 are butted together to form the welding and fixing assembly with an annular structure; the inner diameter of the fixing piece 5 is matched with the outer diameter of the PE pipe body 1, an arc-shaped reinforcing piece 6 arranged along the circumferential direction of the fixing piece 5 is further arranged on the inner side wall of the fixing piece 5, the arc-shaped reinforcing piece 6 and the fixing piece 5 are of an integrally formed structure, the inner diameter of the reinforcing piece 6 is matched with the outer diameter of the welding portion 3, and the length of the reinforcing piece 6 in the horizontal direction is 1.6-1.85 times of the length of the welding portion 3 in the horizontal direction; when the welding part fixing device is used, after the welding parts 3 on the two PE pipe bodies 1 are welded together through a welding machine, the welding fixing component is fixed at the welding parts of the two PE pipe bodies 1 through screws, specifically, the inner side wall of the fixing piece 5 is abutted against the outer wall of the corresponding position of the PE pipe body, and the inner side wall of the reinforcing piece 6 is correspondingly abutted against the outer side wall of the welding part 3;
