[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0013] 1. In this utility model, the antibacterial inner cylinder installed inside the water supply pipe body and the filter plate installed in the antibacterial inner cylinder can effectively inhibit the reproduction of bacteria, algae and other microorganisms in the pipe and filter out mud, rust, particulate matter and other substances in the water, thereby ensuring the safety of the water quality in the home and avoiding pipe blockage. At the same time, the antibacterial inner cylinder and filter plate inside the water supply pipe body are both movable and pressed together, so they can be disassembled and replaced after long-term use to ensure the antibacterial filtration effect during use.
[0014] 2. In this utility model, the vertical reinforcing strips and horizontal reinforcing rings arranged on the inner and outer walls of the water supply pipe body can also uniformly enhance the overall compressive strength and impact resistance of the water supply pipe body, so as to prevent deformation or breakage of the water supply pipe body during use.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0024] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a threaded household water supply pipe.
[0025] Example 1:
[0026] Combination Figure 1-5 As shown, this utility model provides a threaded household water supply pipe, comprising: a water supply pipe body 100 and an installation assembly 200; the installation assembly 200 includes an antibacterial inner cylinder 201 movably installed inside the water supply pipe body 100, a filter plate 202 movably installed inside the antibacterial inner cylinder 201, a bottom fixing ring 203 fixedly installed at the bottom of the antibacterial inner cylinder 201, an embedded sealing ring 204 fixedly installed at the inner end of the bottom fixing ring 203, multiple sets of reinforcing strips 205 arranged and fixedly installed on the inner wall of the water supply pipe body 100, and multiple sets of reinforcing rings 205 arranged and fixedly installed on the outer wall of the water supply pipe body 100. 06. The top and bottom of the water supply pipe body 100 are respectively provided with an external threaded pipe port 207 and an internal threaded pipe port 208, and the external threaded pipe port 207 and the internal threaded pipe port 208 are movably matched and connected. A support ring 209 is fixedly installed on the inner wall of the antibacterial inner cylinder 201, and the filter plate 202 is located on the upper end of the support ring 209. Multiple sets of slots 210 are arranged on the outer wall of the antibacterial inner cylinder 201, and the slots 210 are matched with the reinforcing strip 205. A sealing ring 211 is movably installed at the bottom of the bottom fixing ring 203. The inner wall of the antibacterial inner cylinder 201 is coated with an antibacterial coating.
[0027] Specifically, threaded household water supply pipes refer to water supply pipes with external or internal threads at the ends, which achieve pipe sealing through rotational connection. The antibacterial inner cylinder 201 and the filter plate 202 installed inside the pipe body 100 effectively inhibit the growth of bacteria, algae, and other microorganisms in the pipe and filter out sediment, rust, and particulate matter in the water, thereby ensuring the safety of household water quality and preventing pipe blockage. Furthermore, both the antibacterial inner cylinder 201 and the filter plate 202 inside the pipe body 100 are movable and press-fitted, allowing for disassembly and replacement after prolonged use to maintain the antibacterial filtration effect. Vertical reinforcing strips 205 and horizontal reinforcing rings 206 arranged on the inner and outer walls of the pipe body 100 uniformly enhance the overall pressure resistance and impact resistance of the pipe body 100, preventing deformation or breakage during use. The antibacterial inner cylinder 201... The bottom fixing ring 203 and the sealing ring 211 installed at the bottom of the bottom fixing ring 203 can be installed in the internal threaded pipe port 208 at the bottom of the water supply pipe body 100. Thus, during the assembly of the water supply pipe body 100, the sealing ring 211 and the bottom fixing ring 203 are pressed together by the external threaded pipe port 207 connected at the bottom, thereby ensuring the seal between the antibacterial inner cylinders 201 connected inside the upper and lower water supply pipe bodies 100. The embedded sealing ring 204 fixedly installed at the inner end of the bottom fixing ring 203 can be pressed onto the upper part of the filter plate 202 after the upper and lower water supply pipe bodies 100 are connected to ensure its installation stability and thus stabilize the water source filtration. The support ring 209 fixedly installed inside the antibacterial inner cylinder 201 is mainly used for the bottom support of the filter plate 202 after installation. The groove 210 at the outer wall of the antibacterial inner cylinder 201 can be matched and installed to the outer end of the reinforcing strip 205, thereby binding the antibacterial inner cylinder 201 inside the water supply pipe body 100 and enhancing its stability.
[0028] Working principle and usage process of this utility model:
[0029] During use, the antibacterial inner cylinder 201 and filter plate 202 at the inner end of the water supply pipe body 100 can inhibit bacteria and filter the water source used in the home during transportation and storage, thereby ensuring the safety of the water source during use. At the same time, the reinforcing strips 205 and reinforcing rings 206 arranged and installed on the inner and outer walls of the water supply pipe body 100 can also enhance the overall strength of the water supply pipe body 100, improve its pressure resistance and impact resistance during use, and ensure safety during use. When the water supply pipe body 100 has been used for a long time, it can also be rotated and disassembled to replace its inner antibacterial inner cylinder 201 and filter plate 202 to ensure its antibacterial and filtration effect during use.
