Description

Technical Field

[0001] This utility model relates to the field of HDPE water supply pipe technology, and in particular to an HDPE water supply pipe with a pressure-resistant mechanism. Background Technology

[0002] HDPE water supply pipes are plastic pipes made of high-density polyethylene (HDPE) through extrusion molding, used for transporting tap water, drinking water, etc. Their regular molecular structure and high crystallinity endow the pipes with a series of excellent properties suitable for various water supply scenarios, making them one of the mainstream pipe materials in municipal water supply, building water supply and drainage, and rural drinking water safety projects.

[0003] However, traditional HDPE pipes still have certain drawbacks. For example, in actual laying scenarios, pipes need to withstand soil pressure, ground loads and external impacts. However, existing pipes mainly enhance their compressive strength by thickening them during production. Thickening leads to increased pipe costs, which is wasteful, especially when buried in areas where compressive strength is not required, and lacks practicality. Utility Model Content

[0004] The purpose of this utility model is to provide an HDPE water supply pipe with a pressure-resistant mechanism, which can increase the external pressure resistance of the HDPE water supply pipe, thereby improving the performance.

[0011] According to the HDPE water supply pipe with a pressure-resistant mechanism, the lower and upper reinforcing sheaths are made of glass fiber.

[0028] Connecting assembly 6 includes a housing 7, a threaded rod 8, an internal hexagonal block 9, a limiting block 10, a connecting frame 11, a trapezoidal block 12, a plug 13, an inclined block 14, and a spring 15. The inner surface of the housing 7 is rotatably connected to the threaded rod 8. The upper end of the threaded rod 8 is fixedly connected to the internal hexagonal block 9, and the lower end of the threaded rod 8 is fixedly connected to the limiting block 10. The outer surface of the threaded rod 8 is threadedly connected to the connecting frame 11. The lower end of the connecting frame 11 is fixedly connected to the trapezoidal block 12. The inner surface of the housing 7 is slidably connected to the plug 13. The upper surface of the plug 13 is fixedly connected to the inclined block 14. The outer surface of the plug 13... The inner surface of the positioning groove 16 is fixedly connected to the spring 15, and the inner surface of the positioning groove 16 is adapted to the insertion box 7 to facilitate the installation of the lower half reinforcing sleeve 3 and the upper half reinforcing sleeve 5. The inner surface of the slot 17 is adapted to the insertion block 13 to facilitate the fixing of the lower half reinforcing sleeve 3 and the upper half reinforcing sleeve 5. The outer surface of the lower half reinforcing sleeve 3 is fixedly connected to the insertion box 7. The outer surface of the connecting bracket 11 is slidably connected to the insertion box 7. The outer surface of the trapezoidal block 12 is slidably connected to the insertion box 7. The outer surface of the trapezoidal block 12 is slidably connected to the inclined block 14. The outer surface of the insertion block 13 is slidably connected to the insertion box 7. The outer surface of the inclined block 14 is slidably connected to the insertion box 7.

[0029] Working principle: When the HDPE water supply pipe 1 needs to increase its pressure resistance at a certain point, firstly, wrap the lower half of the reinforcing sleeve 3 around the corresponding HDPE water supply pipe 1, and make the first protective pad 2 fit with the HDPE water supply pipe 1. Then, align the positioning groove 16 on the upper half of the reinforcing sleeve 5 with the insertion box 7 and pass it through, and make the second protective pad 4 fit with the HDPE water supply pipe 1. Then, when the insertion block 13 corresponds to the slot 17, use a hex wrench to turn the internal hexagonal block 9, driving the threaded rod 8 to slide the trapezoidal block 12 down the inclined surface on the inclined block 14 under the limiting action of the limiting block 10. This will drive the two corresponding insertion blocks 13 to unfold outward, thereby inserting them into the slot 17, and stretching the spring 15, thus completing the limiting and fixing installation of the upper half of the reinforcing sleeve 5. This allows the first protective pad 2 and the lower half of the reinforcing sleeve 5 to be inserted into the slot 17. The reinforced sheath 3, the second protective pad 4, and the upper reinforced sheath 5 provide external protection for the HDPE water supply pipe 1. When the HDPE water supply pipe 1 is subjected to external impact, the protection of the lower reinforced sheath 3 and the upper reinforced sheath 5, as well as the buffering effect of the first protective pad 2 and the second protective pad 4, can increase the pressure resistance of the HDPE water supply pipe 1. Furthermore, when the lower reinforced sheath 3 and the upper reinforced sheath 5 are damaged, simply rotate the internal hexagonal block 9 in the opposite direction as described above to drive the trapezoidal block 12 upward. Under the rebound force of the spring 15, the insert block 13 will retract into the insert box 7, thereby releasing the restriction effect on the upper reinforced sheath 5. Then, the entire upper reinforced sheath 5 can be pulled out along the inside of the positioning groove 16 to complete the disassembly. At this time, the lower reinforced sheath 3 or the upper reinforced sheath 5 can be replaced, making it highly practical.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
