Detailed Implementation

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0018] Figures 1 to 9 This is a schematic diagram of the structure of this utility model.

[0019] The attached figures are labeled as follows: universal tube body 1, inner tube 11, shaping tube 12, metal kit 2, steel outer sleeve 21, anti-detachment groove 211, inner sleeve 22, metal inner sleeve 221, inner rubber ring 222, plastic inner sleeve 223, crimp sleeve 2231, sealing ring 224, inner plug 23, anti-detachment protrusion ring 231, flat gasket 232, adapter 3, front positioning protrusion ring 31, adapter protrusion 32, mesh nozzle sleeve 4, filter screen 41, silicone outer tube 5, insertion nut 6, inner positioning protrusion ring 61, sealing flat gasket 7, water control valve 8.

[0020] like Figures 1 to 9 As shown, this utility model discloses a universal shaped tube structure, which includes a universal tube body 1. The universal tube body 1 consists of a flexible inner tube 11 and a stainless steel shaped tube 12 sleeved around the outer periphery of the inner tube 11. The inner tube 11 is made of PVC material and is mainly used as a water conveying pipe. The shaped tube 12 is made of 201 stainless steel and serves as a framework for shaping the flexible inner tube 11. The shaped tube 12 can be a commonly used shaped tube on the market. The shaped tube is generally multi-sectioned, and the sections can rotate appropriately in multiple directions, so the shaped tube can be manually bent to present different spatial orientations. By bending, the universal shaped tube of this utility model can present various shapes, and the water outlet angle of the universal shaped tube can also be adjusted at any time by bending, making it particularly suitable for use in household kitchens, bathrooms, etc.

[0021] The universal tube body 1 of this utility model has metal fittings 2 press-fitted to both its inlet and outlet ends. The ends of the universal tube body 1 with the metal fittings 2 press-fitted to both ends are clean and easy to connect with other components. For example... Figures 1 to 4 As shown, the metal kit 2 of this utility model consists of a steel outer sleeve 21, an inner sleeve 22, and an inner plug 23 from the outside in. The steel outer sleeve 21 is made of 304 stainless steel, with a beautiful and high-end appearance. The inner sleeve 22 and the inner plug 23 can be made of metal or non-metal materials. The pressing method of the metal kit 2 and the universal tube body 1 is as follows: the end of the shaping tube 12 is pressed and fixed in the port between the steel outer sleeve 21 and the inner sleeve 22. The shaping tube 12 extends from both ends of the inner tube 11, and the end of the inner tube 11 is pressed and fixed between the inner plug 23 and the inner sleeve 22.

[0022] from Figure 8 , Figure 5 and Figure 6As can be seen, in order to ensure that the inner tube 11 is pressed firmly, this utility model provides multiple anti-detachment protrusions 231 on the outer circumferential surface of the inner plug 23, and the cross-section of the anti-detachment protrusions 231 is triangular. The outer end of the inner plug 23 is also integrally formed with a flat pad 232, the diameter of which is larger than the diameter of the inner plug 23. After the metal kit 2 is pressed into place, the outer end face of the inner tube 11 and the outer end face of the inner sleeve 22 are positioned and matched with the inner side of the flat pad 232. The flat pad 232 matches the outer port of the steel outer sleeve 21 to seal the ends of the inner tube 11 and the inner sleeve 22 in the port of the outer steel outer sleeve 21, so that the ends of the inner tube 11 and the shaping tube 12 are not visible from both ends of the universal shaping tube.

[0023] When the inner sleeve 22 of this utility model is a metal inner sleeve 221 extruded from metal material, such as Figure 1 , Figure 3 and Figure 5 As shown, at this time, the end of the shaping tube 12 is press-fitted and fixed in the inner port between the steel outer sleeve 21 and the metal inner sleeve 221. The metal inner sleeve 221 can be a copper inner sleeve or a steel inner sleeve made of 304 stainless steel. When the metal inner sleeve 221 is used, an inner rubber ring 222 is filled in the outer port between the steel outer sleeve 21 and the metal inner sleeve 221. The inner rubber ring 222 can ensure the sealing performance between the steel outer sleeve 21 and the metal inner sleeve 221.

[0024] When the inner sleeve 22 of this utility model is a non-metallic inner sleeve made of non-metallic material, such as Figure 2 , Figure 4 and Figure 6 As shown, the non-metallic inner sleeve at this time is a plastic inner sleeve 223, which is injection molded from plastic using an injection molding process. The plastic inner sleeve 223 is disposed in the outer port of the steel outer sleeve 21. The plastic inner sleeve 223 is formed with a rearwardly extending crimp sleeve 2231, and the end of the shaping tube 12 is press-fitted and fixed in the port between the steel outer sleeve 21 and the crimp sleeve 2231. In order to ensure the sealing performance between the plastic inner sleeve 223 and the steel outer sleeve 21, a sealing ring 224 is fitted on the plastic inner sleeve 223.

[0025] In this embodiment, the outer circumferential surface of the steel jacket 21 may be machined with external threads, allowing it to connect with other components via these threads. For example... Figure 1 and Figure 2 As shown, an adapter 3 is spirally installed on the steel sleeve 21 at the water outlet end of the universal tube body 1, which can also be connected to a shower head. When the adapter 3 is installed, the universal tube of this invention can be used in kitchens and on washing machine countertops. When a shower head is installed, the universal tube of this invention can be used in bathroom shower rooms. Figure 7As shown, the outer port of the adapter 3 of this utility model is formed with a front positioning protrusion 31 extending towards the center. The front positioning protrusion 31 can cooperate with the flat pad portion 232 of the inner plug 23 to play a positioning role. In order to prevent water leakage when the adapter 3 is connected to the steel outer sleeve 21, a sealing flat pad 7 is press-fitted between the inner end face of the front positioning protrusion 31 and the flat pad portion 232 of the inner plug 23.

[0026] The outer end face of the front positioning protrusion 31 of this utility model has a connecting protrusion 32 formed thereon, and a mesh sleeve 4 is spirally installed through the connecting protrusion 32. The mesh sleeve 4 is provided with a filter screen 41. This utility model has a filter screen 41 in the mesh sleeve 4. The filter screen 41 can filter out the mud and sand in the water, thereby making the water more hygienic.

[0027] In order to extend the service life of this utility model and improve the aesthetics and high-end appearance of the product, such as Figure 1 and Figure 2 As shown, this utility model can optionally include a protective silicone outer tube 5 fitted around the outer periphery of the universal tube body 1. The silicone outer tube 5 can be made in multiple colors to meet the usage requirements of different users.

[0028] Both ends of the universal tube body 1 of this utility model can be metal fittings 2 with metal inner sleeves 221 or metal fittings 2 with plastic inner sleeves 223. Of course, one end of the universal tube body 1 can also be metal fittings 2 with plastic inner sleeves 223 and the other end can be metal fittings 2 with metal inner sleeves 221.

[0029] like Figure 3 and Figure 4 As shown, the metal fitting 2 installed at the water inlet end of the universal pipe body 1 of this utility model can be further designed as an extended three-groove metal fitting with a metal inner sleeve. This three-groove metal fitting can be inserted into other pipe fittings or valve fittings to achieve quick plug-in connection. When the metal fitting 2 installed at the water inlet end of the universal pipe body 1 is a three-groove metal fitting, the three-groove metal fitting is composed of an extended three-groove stainless steel outer sleeve, an extended three-groove stainless steel inner sleeve, and an inner plug 23 in sequence, and a three-groove inner rubber ring is installed in the outer port between the three-groove stainless steel inner sleeve and the three-groove stainless steel outer sleeve. The port circumference of the three-groove stainless steel outer sleeve is also rolled with three anti-detachment grooves 211 for preventing detachment during plug-in connection.

[0030] In the embodiments, such as Figure 1 and Figure 2 As shown, when the outer circumferential surface of the steel sleeve 21 of this utility model can be machined with external threads, a socket nut 6 can also be fitted onto the outer steel sleeve 21 at the water inlet end of the universal tube body 1 through its external threads. Figure 9 As shown, the universal shaping tube of this utility model can be matched with the water control valve 8 through the nut 6.

[0031] from Figure 1 and Figure 2 It can be seen that when the universal tube body 1 of this utility model is equipped with a silicone outer tube 5 and an adapter 3 and a socket nut 6 are installed, one end of the silicone outer tube 5 is preferably inserted into the port between the outer steel sleeve 21 and the adapter 3, and the other end of the silicone outer tube 5 is inserted into the port between the outer steel sleeve 21 and the socket nut 6.

[0032] In the embodiment, an inner positioning protrusion ring 61 is formed in the inner hole of the plug nut 6 of this utility model, and a sealing gasket 7 is also press-fitted between the inner positioning protrusion ring 61 and the flat gasket portion 232 of the inner plug 23.

[0033] The advantages of this utility model are: the two ends of the shaping tube 12 are press-fitted and fixed between the steel outer sleeve 21 and the inner sleeve 22, and the two ends of the inner tube 11 are press-fitted between the inner plug 23 and the inner sleeve 22, thereby ensuring the stability of the connection between the metal kit 2 and the universal tube body 1, eliminating the problem of easy breakage and leakage at the joints at both ends of the traditional universal shaping tube, and the universal shaping tube of this utility model can also be directly connected to the water control valve of the household kitchen. It can utilize the universal characteristics of the shaping tube to change the shape of the universal shaping tube at any time and adjust the water outlet angle of the universal shaping tube, so as to better meet the needs of people's household use.

[0034] The preferred embodiment of this utility model has been described, and various changes or modifications made by those skilled in the art will not depart from the scope of this utility model.
