DETAILED DESCRIPTION

[0018] The specific implementation of the utility model will be further described below in combination with the drawings. It needs to be explained here that the description of these implementation modes is used to help understanding the utility model, but does not constitute the limitation to the utility model. In addition, the technical features involved in each implementation of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] As Figures 1-4 shown:

[0020] The utility model discloses a kind of MASPP power sheath pipes, including two sides MASPP pipe body 1 and joint assembly, the joint assembly is made of male joint 2 and female joint 3, inside male joint 2 is sleeve A 21, sleeve B 22 is connected concentrically with the circular platform section 23 in the outer periphery of sleeve A 21, and the circular platform section 23 is equiangularly opened with several transverse fan-shaped through holes 231 on the circumference surface;Inside female joint 3 is spigot A 31, and it is connected with sleeve A 21 using plug-in sealing connection;Spigot B 34 is connected concentrically with positioning disc 33 on the outer periphery of spigot A 31, and spigot B 34 rear end connects reducing pipe 32, and the outer diameter of spigot B 34 is consistent with the inner diameter of sleeve B 22, and the position corresponding fan-shaped through hole 231 is provided with the hook handle 35 of outer periphery groove 351 at the front end of spigot B 34, and spigot B 34 is inserted into sleeve B 22, and hook handle 35 is fixed by detachable snap ring 4 after passing through fan-shaped through hole 231;MASPP pipe body 1 is connected using screw thread with sleeve A 21 and reducing pipe 32.

[0021] The utility model discloses in use, first with male joint 2 and female joint 3 respectively with MASPP pipe body 1 butt joint, then mutually butt joint, and spigot A 31 is inserted into sleeve A 21 when butt joint, in order to promote sealing performance, can be opened with several annular grooves in the outer periphery wall of spigot A 31, and the sealing ring 311 is installed in annular groove.

[0022] Butt joint simultaneously spigot B 34 is also inserted into sleeve B 22, and the hook handle 35 part of spigot A 31 front end is inserted from the position of fan-shaped through hole 231, and then can be completed butt joint after being clamped in the groove 351 of the outer periphery of hook handle 35 by snap ring 4, although groove 351 can be directly opened on pipe wall, but such pipe wall strength is not enough, so hook handle 35 and spigot B 34 can be made into equal wall thickness, and the part of hook handle 35 is formed by bending to the axis direction of spigot B 34, so that the part where hook handle 35 is located can be integrally injection molded with spigot B 34 into tubular shape, and hook handle 35 can be formed after cutting into notch 36 in the area outside fan-shaped through hole 231, which can greatly reduce the difficulty and process of production.

[0023] Since snap ring 4 does not need to be completely removed, it only needs to be separated from groove 351, so snap ring 4 is machined to have only one opening, and lug plate 41 is arranged at the opening, and lug plate 41 is connected by bolt, so that it can be slightly broken to complete the action of clamping and unclamping, and at this time, the effect of the clamping relative to a pin, the side of snap ring 4 facing the circular platform section 23 can be machined into a circular platform surface matched with it, so that the contact surface is large and not easy to deform.

[0024] The embodiments of the utility model are described in detail in combination with the drawings, but the utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the utility model, and still fall within the protection scope of the utility model.
