[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0030] See also Figure 1-4 The PVC pipe that is easy to disassemble and assemble provided in this embodiment includes a PVC pipe 1. The outer wall of the PVC pipe 1 is provided with two groups of mutually symmetrical protective shells 2, and the front and rear ends of the outer wall of one group of protective shells 2 are provided with two groups of mutually symmetrical first fixing sleeves 6. The front and rear ends of the outer wall of the other group of protective shells 2 are provided with two groups of mutually symmetrical second fixing sleeves 7. The upper and lower ends of the outer wall of the first fixing sleeve 6 close to the second fixing sleeve 7 are provided with two groups of mutually symmetrical positioning blocks 8. The upper and lower ends of the outer wall of the second fixing sleeve 7 are provided with positioning grooves 9. The outer walls of the first fixing sleeve 6 and the second fixing sleeve 7 are provided with connecting sleeves 10. The outer walls of the left and right ends of the connecting sleeve 10 are inserted with four groups of second bolts 11 that are symmetrical in pairs.

[0031] In an embodiment further provided by the present invention, the protective shell 2 is configured to be semi-cylindrical, and the two groups of protective shells 2 are symmetrical with each other with the center of the PVC pipe 1 as the axis and fit together. The inner and outer walls of the protective shell 2 and the outer wall of the PVC pipe 1 have the same radius, and the protective shell 2 is movably sleeved on both sides of the outer wall of the PVC pipe 1.

[0032] Furthermore, two sets of mutually symmetrical fixing blocks 3 are fixed at the upper and lower ends of the outer wall of the protective shell 2, and a first bolt 4 is threadedly inserted into the middle end of the fixing block 3. The first bolt 4 threads through the two sets of fixing blocks 3 located in the same horizontal plane, and a nut 5 is threadedly sleeved on the outer wall of the first bolt 4, and the nut 5 and the fixing block 3 fit together.

[0033] Furthermore, the first fixing sleeve 6 and the second fixing sleeve 7 are configured to be semi-cylindrical, and the first fixing sleeve 6 and the second fixing sleeve 7 are fixedly sleeved on the upper end of the outer wall of the protective shell 2 .

[0034] In an embodiment further provided by the present invention, the positioning block 8 is movably inserted into the positioning groove 9 .

[0035] In the embodiment provided by the present invention, the connecting sleeve 10 is movably sleeved on the outer walls of the first fixing sleeve 6 and the second fixing sleeve 7 , and the outer wall radius of the first fixing sleeve 6 is equal to the inner wall radius of the connecting sleeve 10 .

[0036] Specifically, four groups of second bolts 11 are symmetrically inserted into the outer walls of the left and right ends of the connecting sleeve 10, and threaded holes 12 that match the second bolts 11 are opened on the outer walls of the first fixing sleeve 6 and the second fixing sleeve 7. The front end of the second bolt 11 can move through the connecting sleeve 10 and is threaded into the threaded hole 12.

[0037] Working principle: align the positioning block 8 with the positioning groove 9 and insert the positioning block 8 into the positioning groove 9. At this time, the two sets of protective shells 2 are merged into a complete cylindrical shape. The PVC pipe 1 is wrapped in the protective shell 2, and the fixing blocks 3 correspond one to one. Rotate and insert the first bolt 4 into the fixing block 3, then turn the nut 5 to fit the nut 5 and the fixing block 3 tightly. The installation of the protective shell 2 can be completed. The PVC pipe 1 is wrapped inside the protective shell 2, which protects the PVC pipe 1 well. This solves the problem that the existing PVC pipe 1 lacks certain protective devices and is easily corroded by the outside world.

[0038] When it is necessary to dock two groups of PVC pipes 1, the first fixing sleeve 6 and the second fixing sleeve 7 on the outer wall of the end of the PVC pipe 1 are fitted with the first fixing sleeve 6 and the second fixing sleeve 7 of the other group, and then the connecting sleeve 10 is sleeved on the outer walls of the two groups of first fixing sleeves 6 and the second fixing sleeve 7, and then the second bolt 11 is rotated and the front end of the second bolt 11 is screwed into the threaded hole 12 to complete the docking of the two groups of PVC pipes 1. When it is necessary to disassemble the PVC pipe 1, the second bolt 11 is unscrewed from the threaded hole 12 to cancel the docking between the PVC pipes 1 and the PVC pipes 1, which solves the problem that most of the PVC pipes 1 used outdoors are fixed by welding. When internal blockage occurs, the pipes often need to be sawed off, which is a time-consuming and laborious operation.

[0039] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
