[0022] The following is in conjunction with the appendix Figures 1-5 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0023] like Figures 1-5 As shown, this utility model discloses a PVC drain pipe with a pressure-resistant reinforced layer, comprising a pipe body 1. Multiple lower half-rings 2 are fitted onto the outer wall of the pipe body 1, and the lower half-rings 2 are fixedly connected in pairs by connecting strips 3. An upper half-ring 4 is provided on the upper end face of the lower half-rings 2, which slides into the pipe body 1. The upper half-ring 4 is connected to the lower half-rings 2 by a snap-fit ​​mechanism. A supporting outer ring 5 slides into the inner wall of the pipe body 1, and a supporting inner ring 6 is provided inside the supporting outer ring 5. The supporting inner ring 6 is fixedly connected to the supporting outer ring 5 by multiple supporting columns 7. This device protects the pipe body 1 and enhances its pressure resistance by using multiple lower half-rings 2 and upper half-rings 4 outside the pipe body 1, and provides support from the inside by setting the supporting outer ring 5 and supporting inner ring 6 inside the pipe body 1, thus enhancing its pressure resistance from within. Simultaneously, the pipe body 1 itself is provided with a reinforcing layer 102 and a pressure-resistant layer 103, making the pipe body 1 stronger and less prone to damage under pressure.

[0024] Specifically, the snap-fit ​​mechanism includes a groove 8 horizontally formed on the inner wall of the lower half ring 2. A snap-fit ​​rod 10 is fixedly installed on the inner wall of the groove 8 by a spring 9. The snap-fit ​​rod 10 is movably embedded into the outer wall of the upper half ring 4. The snap-fit ​​rod 10 is used to realize the installation and docking of the lower half ring 2 and the upper half ring 4, making the docking and installation of the lower half ring 2 and the upper half ring 4 faster and saving installation time.

[0025] More specifically, the lower half ring 2 has a sliding engagement member 11 on its outer wall. The engagement member 11 is fixedly connected to the locking rod 10 through a steel wire 12 that passes through the lower half ring 2. The spring 9 is movably sleeved on the outer wall of the steel wire 12. Pulling the engagement member 11 can directly cancel the locking of the locking rod 10 to the upper half ring 4, making it more convenient to cancel the locking between the upper half ring 4 and the lower half ring 2.

[0026] Further, the pipe body 1 is sleeved with a protection ring 13 at both ends, the protection ring 13 sleeving the pipe body 1 at the end to prevent the pipe body 1 from being damaged by pressure.

[0027] Further, the pipe body 1 comprises an inner pipe 101, the inner pipe 101 is provided with a reinforcing layer 102, the reinforcing layer 102 is made of ABS material, the reinforcing layer 102 is provided with a pressure-resistant layer 103, the pressure-resistant layer 103 is made of rubber material, and the pressure-resistant layer 103 is provided with an outer pipe 104.

[0028] Working principle:

[0029] The lower half ring 2 is sleeved on the pipe body 1, then the upper half ring 4 is sleeved on the pipe body 1, the pulling member 11 is pulled outward, the pulling member 11 indirectly drives the clamping rod 10 to move through the transmission of the steel wire 12, the clamping rod 10 is retracted into the groove 8 against the action force of the spring 9, the upper half ring 4 is butt-jointed with the lower half ring 2, then the pulling member 11 is loosened, the spring 9 pushes the clamping rod 10 to reset to insert and fix the upper half ring 4, the above steps are repeated to complete the installation of the plurality of lower half rings 2 and the upper half rings 4.
