Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

As shown in fig. 1-3, a PP tube with wear-resistant ends convenient for butt joint comprises a tube body 1, a connecting mechanism and edge strips 3, wherein the connecting mechanism is mounted at two ends of the tube body 1 and used for efficient and firm butt joint, and the edge strips 3 are mounted on the side wall of the tube body 1.

The connecting mechanism comprises an inner groove 201, an insertion pipe 204 and a fixing bolt 207, wherein the inner groove 201 is formed in the left end edge of the pipe body 1, limiting grooves 202 are formed in the outer sides of the front side and the rear side of the inner groove 201, a first spiral groove 203 is formed in the outer side of the limiting groove 202, the fixing bolt 207 is meshed and mounted in the first spiral groove 203, the insertion pipe 204 is welded to the outer side of the right end edge of the pipe body 1, a limiting strip 205 is welded to the outer sides of the front side and the rear side of the insertion pipe 204, and a second spiral groove 206 is formed in the limiting strip 205 and the insertion pipe 204 in a penetrating mode; the connection between the pipe bodies 1 is more efficient.
