[0025] Reference Figure 1 As shown, a sanitary connecting pipe provided according to an embodiment of the present invention includes a pipe body 100 and a reinforcement member 200. The pipe body 100 is provided with a first chuck 110 and a second chuck 120. The first chuck 110 and the second chuck 120 are spaced apart along the radial direction of the pipe body 100. For example, the first chuck 110 can be provided at one end of the pipe body 100, and the second chuck 120 can be provided on the outer peripheral wall of the middle section of the pipe body 100.
[0026] The reinforcement 200 is covered on the outer peripheral wall of the first chuck 110, the outer peripheral wall of the second chuck 120 and the outer peripheral wall of the tube body 100 between the first chuck 110 and the second chuck 120, and the two side end faces of the reinforcement 200 are respectively flush with the two side end faces opposite to the first chuck 110 and the second chuck 120; wherein, the reinforcement 200 is a metal part.
[0027] It is understood that by providing the reinforcement member 200, the reinforcement member 200 covers the outer peripheral wall of the first chuck 110 and the outer peripheral wall of the second chuck 120, effectively improving the strength of the first chuck 110 and the second chuck 120, and the reinforcement member 200 covers the pipe body 100 between the first chuck 110 and the second chuck 120, effectively improving the overall structural strength of the pipe body 100. When the clamp 300 is connected to the sanitary connection pipe, the metal clamp 300 and the metal reinforcement member 200 are in contact and fixed, and the reinforcement member 200 is not prone to fatigue deformation under the pressure impact in the pipe. This can effectively enhance the sealing performance and pressure resistance of the connection between the sanitary connection pipe and the clamp 300, ensure the overall pressure resistance of the system, and extend the service life of the sanitary connection pipe. In addition, the end faces of the reinforcement member 200 are flush with the end faces of the first chuck 110 and the second chuck 120, respectively, which can increase the contact area between the sanitary connection pipe and other components, optimize the stress structure, and further improve the connection stability.
[0028] Reference Figure 1 and Figure 2 As shown, it can be understood that the reinforcement 200 includes two half-cylinders 210 of the same shape and size, and the two half-cylinders 210 are cold-welded.
[0029] Since the tube body 100 is provided with the first chuck 110 and the second chuck 120, the reinforcement member 200 cannot be installed on the outside of the tank body in a traditional sleeve manner. The reinforcement member 200 is divided into two identical semi-cylinders 210, which can facilitate the user to assemble the semi-cylinders 210 and improve the assembly convenience of the reinforcement member 200.
[0030] Reference Figure 2 As shown, it can be understood that the semi-cylinder 210 includes a first reinforcement section 211, a straight section 212 and a second reinforcement section 213. The first reinforcement section 211 and the second reinforcement section 213 are respectively located on both sides of the straight section 212. The first reinforcement section 211 is provided with a first positioning groove 2111 that matches the shape of the first chuck 110, the straight section 212 is provided with a semicircular groove 2121 that matches the shape of the tube body 100, and the second reinforcement section 213 is provided with a second positioning groove 2131 that matches the shape of the second chuck 120.
[0031] The semi-cylinder 210 is radially divided into a first reinforcement section 211, a straight section 212 and a second reinforcement section 213. The first reinforcement section 211 is arranged corresponding to the first chuck 110, the straight section 212 is arranged corresponding to the tube body 100, and the second reinforcement section 213 is arranged corresponding to the second chuck 120. This can effectively improve the fit between the semi-cylinder 210 and the sanitary connecting pipe, and ensure that when the two semi-cylinders 210 are cold-welded and fixed to form the reinforcement 200, the inner circumferential wall of the reinforcement 200 and the outer circumferential wall of the first chuck 110, the outer circumferential wall of the second chuck 120 and the outer circumferential wall of the tube body 100 between the first chuck 110 and the second chuck 120 are tightly fitted, thereby effectively improving the installation stability of the reinforcement 200.
[0032] Furthermore, the first reinforcement section 211 , the straight section 212 and the second reinforcement section 213 are integrally formed parts.
[0033] The first reinforcement section 211, the straight section 212 and the second reinforcement section 213 can be integrally formed by welding, injection molding, die casting, etc., which effectively improves the structural strength of the semi-cylinder 210 and further enhances the sealing performance and pressure resistance of the connection between the sanitary connecting pipe and the clamp 300.
[0034] Reference Figure 3As shown, according to another embodiment of the present invention, a sanitary piping system includes a plurality of the aforementioned sanitary connecting pipes, with a clamp 300 disposed between two adjacent sanitary connecting pipes. The clamp 300 is fastened to two opposing reinforcement members 200 of the two adjacent sanitary connecting pipes. Specifically, the first clamps 110 on the two adjacent sanitary connecting pipes are disposed opposite each other, and the clamp 300 is fastened to the outside of the first reinforcement section 211 of the two opposing reinforcement members 200 of the two adjacent sanitary connecting pipes. Alternatively, the second clamps 120 on the two adjacent sanitary connecting pipes are disposed opposite each other, and the clamp 300 is fastened to the outside of the second reinforcement section 213 of the two opposing reinforcement members 200 of the two adjacent sanitary connecting pipes.
[0035] It should be noted that when the second chuck 120 of one of the sanitary connecting pipes is arranged on the outer peripheral wall of the middle section of the pipe body 100, the second chuck 120 of the other sanitary connecting pipe is arranged at the end of the pipe body 100, and the inner diameter of the pipe body 100 of the sanitary connecting pipe is larger than the outer diameter of the pipe body 100 where the second chuck 120 is arranged on the outer peripheral wall, so that the two adjacent sanitary connecting pipes form a sleeve structure to ensure that the two second chucks 120 are arranged relative to each other.
[0036] Since the sanitary piping system provided by the embodiment of the present invention includes the above-mentioned sanitary connecting pipe, the sanitary piping system provided by the embodiment of the present invention also has the beneficial effects described in the above-mentioned embodiment, which will not be described in detail here.
[0037] Reference Figure 1 and Figure 3 As shown, it can be understood that the inner wall of the clamp 300 is provided with a first locking portion, and the reinforcement 200 is provided with a second locking portion 220, and the first locking portion and the second locking portion 220 cooperate to lock the tube body 100. Optionally, the first locking portion and the second locking portion 220 can be configured as mutually cooperating locking block and locking groove structures, magnetic structures, serrated structures, etc., which will not be repeated here.
[0038] By providing the first locking portion and the second locking portion 220 , the connection tightness of the reinforcement 200 between two adjacent sanitary connecting pipes can be further strengthened on the basis of fastening and fixing the clamp 300 , thereby enhancing the sealing performance and pressure resistance of the entire sanitary pipe system.
[0039] Furthermore, the first locking portion is configured as a first tapered surface provided on the inner circumferential wall of the clamp 300, and the second locking portion 220 is configured as a second tapered surface 221 that matches the first tapered surface. The second tapered surface 221 is provided on opposite sides of the first reinforcement section 211 and the second reinforcement section 213. When the clamp 300 is fastened to the reinforcement member 200, the first tapered surface presses against the second tapered surface 221 on the reinforcement member 200, thereby locking the reinforcement member 200.
[0040] The first locking portion and the second locking portion 220 are configured as matching first conical surfaces and second conical surfaces 221. On the premise of ensuring that the clamp 300 can lock the reinforcement 200, the structure of the clamp 300 and the reinforcement 200 can be simplified, the design cost of the clamp 300 and the reinforcement 200 can be reduced, and the assembly and use of the clamp 300 can be facilitated.
[0041] Reference Figure 3 As shown, it can be understood that the sanitary pipe connection structure also includes a gasket 400, which abuts between the two opposite first chucks 110 or the two opposite second chucks 120 between two adjacent sanitary connecting pipes, and the gasket 400 is provided with a center hole 410 with the same inner diameter as the pipe.
[0042] By providing the gasket 400, on the one hand, the gasket 400 can fill the gap between the two first chucks 110 or the two second chucks 120, further improving the sealing performance of the sanitary pipe system; on the other hand, the gasket 400 can avoid direct contact between the two first chucks 110 or the two second chucks 120, absorb the vibration impact of the first chuck 110 or the second chuck 120 during operation, reduce the vibration and noise pollution of the sanitary connecting pipe, and further extend the service life of the sanitary connecting pipe.
[0043] Furthermore, the outer diameter of the washer 400 is equal to the outer diameter of the adjacent first chuck 110 or the outer diameter of the adjacent second chuck 120 .
[0044] Setting the outer diameter of the gasket 400 to be equal to the outer diameter of the adjacent first chuck 110 or the outer diameter of the adjacent second chuck 120 can increase the contact surface between the first chuck 110 or the second chuck 120 and the gasket 400, evenly disperse the stress between the two first chucks 110 or the two second chucks 120, optimize the stress structure, and further improve the sealing and structural stability of the sanitary piping system.
[0045] Furthermore, the first chuck 110 and the second chuck 120 are respectively provided with an annular clamping groove 111 , and both sides of the gasket 400 are respectively provided with an annular protrusion 420 , which can be engaged with the clamping groove 111 .
[0046] By providing the protrusion 420 and the slot 111, the gasket 400 can be clamped between two opposite first chucks 110 or two opposite second chucks 120, preventing the gasket 400 from loosening and affecting the seal, and effectively improving the installation stability and loading and unloading convenience of the gasket 400.
[0047] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
