[0030] Reference Figures 1 to 5In one embodiment of the present invention, a convenient water supply pipe installation device is provided for connecting a water supply pipe 010, and is characterized in that it includes:
[0031] The inner connecting tube 100 includes mutually connected frustum-shaped cones 110 in the longitudinal direction. A channel 120 having an inner diameter consistent with the inner diameter of the water supply pipe 010 is passed through the middle of the cone 110. An annular groove 111 is provided on the outer wall of the cone 110. Each cone 110 corresponds to a port of the water supply pipe 010.
[0032] The expansion assembly 200 includes a main body tube 210 and a movable rod 220 slidably disposed in the middle of the main body tube 210. A plurality of expansion members 230 are hingedly connected to one end of the main body tube 210 in a circumferential direction. One end of the expansion member 230 extends away from the outer wall of the main body tube 210, and the other end of the expansion member 230 extends into the middle of the main body tube 210 and is hingedly connected to the movable rod 220.
[0033] The outer connecting tube 300 is arranged corresponding to the inner connecting tube 100. The outer connecting tube 300 includes two outer tubes 310 connected to each other in the length direction. The interior of the outer tube 310 is a frustum-shaped space. The inner wall of the outer tube 310 is circumferentially provided with a convex ring corresponding to the groove 111 on the conical tube 110. When the inner connecting tube 100 and the outer connecting tube 300 are installed, the outer wall of the inner connecting tube 100 and the inner wall of the outer connecting tube 300 clamp the water supply pipe 010.
[0034] In the existing technology, mechanical connections have the disadvantages of being complex in structure and inconvenient to use. Generally, they include internal and external components, which are complex in structure and difficult to use, and are also prone to affecting the flow field. They also have certain requirements for parameters such as the hardness of the pipeline.
[0035] The convenient installation device for the middle water supply pipe provided by the present invention is used for connecting the water supply pipe 010, and includes an inner connecting tube 100, an outer expansion component 200 and an outer connecting tube 300.
[0036] The inner connecting tube 100 comprises a series of interconnected frustum-shaped cones 110 along its length. This frustum-shaped arrangement allows the inner connecting tube 100 to be inserted into the water supply pipe 010. A channel 120 with an inner diameter consistent with that of the water supply pipe 010 runs through the middle of the cone 110, minimizing the impact of the inner connecting tube 100 on the flow field within the water supply pipe 010. An annular groove 111 is formed around the outer wall of the cone 110.
[0037] The external expansion component 200 includes a main body tube 210 and a movable rod 220 slidably arranged in the middle of the main body tube 210. A plurality of external expansion parts 230 are hingedly connected to one end of the main body tube 210 in the circumferential direction. One end of the external expansion part 230 extends away from the outer wall of the main body tube 210, and the other end of the external expansion part 230 extends into the middle of the main body tube 210 and is hinged to the movable rod 220. When the movable rod 220 is extended and retracted, the swing of the external expansion part 230 can be manipulated. When the external expansion part 230 swings inward, the outer diameter of the entire external expansion component 200 can be reduced, which facilitates the insertion and removal process of the external expansion component 200. When the external expansion part 230 swings outward, the inner part of the external expansion part 230 contacts the inner wall of the water supply pipe 010, thereby forming a fixing effect, thereby facilitating the insertion process of the internal connecting tube 100. When one side of the inner connecting tube 100 is installed, the connection of the other water supply pipe 010 on the inner connecting tube 100 forms a relatively fixed foundation and no longer requires the use of the external expansion component 200.
[0038] The outer connecting tube 300 is provided corresponding to the inner connecting tube 100. The outer connecting tube 300 includes two outer tubes 310 connected to each other in the length direction, and the interior of the outer tube 310 is a frustum-shaped space. A convex ring corresponding to the groove 111 on the conical tube 110 is provided on the inner wall of the outer tube 310 in the circumferential direction. After the outer expansion assembly 200 is taken out and the two water supply pipes 010 are installed on the inner connecting tube 100, the installation of the outer connecting tube 300 is completed. After the inner connecting tube 100 and the outer connecting tube 300 are installed, the outer wall of the inner connecting tube 100 and the inner wall of the outer connecting tube 300 clamp the water supply pipe 010. At this time, the cooperation between the groove 111 and the convex ring can make the clamping process of the water supply pipe 010 more stable. The structural form of the outer connecting tube 300 can be various, such as a flange connection in the length direction, or a bolt connection in the circumferential direction.
[0039] In summary, the inner connecting tube 100 provides a basis for supporting and connecting the ports of the two water supply pipes 010, and the inner diameter of the channel 120 on the inner connecting tube 100 is consistent with the inner diameter of the water supply pipe 010, so that the influence of the inner connecting tube 100 on the flow field inside the water supply pipe 010 is reduced as much as possible; the outward expansion action of the water supply pipe 010 is realized by the outward expansion component 200, thereby facilitating the installation process of the inner connecting tube 100; the outer wall of the inner connecting tube 100 and the inner wall of the outer connecting tube 300 clamp the water supply pipe 010, achieving a fixed connection while providing a sealing effect, and the groove 111 of the inner connecting tube 100 corresponds to the convex ring of the outer connecting tube 300, thereby improving the fixing effect and the sealing effect; the convenient water supply pipe installation device simplifies the connection process of the water supply pipe 010, improves the connection strength, improves the sealing performance and improves the maintainability.
[0040] In one embodiment, the outer connecting tube 300 is an integral structure in the length direction and a connected structure in the circumferential direction.
[0041] In this embodiment, for example, the outer connecting tube 300 includes two tube petals, which are connected by a bolt structure, so as to facilitate installation and clamp the water supply pipe 010 together with the inner connecting tube 100 .
[0042] Reference Figure 5 In one embodiment, the two outer cylinders 310 are a split connection structure in the length direction.
[0043] In this embodiment, for example, the two outer cylinders 310 are connected by flanges, which have the advantages of high strength and strong weather resistance. Different flange models can meet the connection process of different water supply pipes 010.
[0044] Reference Figure 3 In one embodiment, a protruding ring 240 is provided on the outer wall of the movable rod 220 near one end of the outer expansion member 230 , and the outer diameter of the protruding ring 240 is consistent with the inner diameter of the inner connecting tube 100 .
[0045] In this embodiment, the above-mentioned dimensions allow the protruding collar 240 of the movable rod 220 to serve as a guide for the installation of the inner connecting tube 100, thereby reducing the difficulty of installing the inner connecting tube 100. During use, after the outer expansion assembly 200 is installed, the inner connecting tube 100 is sleeved onto the protruding collar 240, thereby accurately positioning the inner connecting tube 100 and simplifying the operation process.
[0046] In one embodiment, the protruding ring 240 is detachably mounted on the movable rod 220 .
[0047] In this embodiment, the detachable protruding collar 240 allows replacement of the protruding collar 240 to accommodate different sizes of the inner connecting tube 100, avoiding replacement of the entire outer expansion assembly 200. It should be noted that the tilting angle of the outer expansion member 230 can adapt to different inner diameters of the water supply pipe 010.
[0048] Reference Figure 5 In one embodiment, the outer cylinder 310 has an overall shape of a frustum.
[0049] In this embodiment, since the outer cylinder 310 is used as a frustum-shaped space, the outer cylinder 310 is configured to have a frustum-shaped overall shape. This can reduce the amount of material used while ensuring performance.
[0050] In one embodiment, the cone 110 is provided with two grooves 111 spaced apart in the length direction.
[0051] In this embodiment, by increasing the number of grooves 111 , the strength of the inner connecting tube 100 and the outer connecting tube 300 in clamping the water supply pipe 010 is improved, and the sealing performance is also improved.
[0052] Reference Figure 1 In one embodiment, the inner connecting tube 100 is an integrally formed structure.
[0053] In this embodiment, the inner connecting tube is limited to an integrally formed structure, thereby ensuring accurate positioning while reducing the difficulty of processing and installation.
[0054] Reference Figures 3 to 4 In one embodiment, the outer end of the external expansion piece 230 is connected to a curved plate corresponding to the inner wall of the water supply pipe 010.
[0055] In this embodiment, the curvature of the arc plate in the length direction matches the inner wall of the water supply pipe 010 , so that the outward expansion component 200 can achieve a more superior outward expansion performance and reduce damage to the water supply pipe 010 .
[0056] In one embodiment, the peripheral walls at both ends of the inner connecting tube 100 in the longitudinal direction have chamfered structures.
[0057] In this embodiment, the inner connecting tube 100 is chamfered at both ends of the longitudinal direction to reduce the possibility of damage to the water supply pipe caused by the inner connecting tube 100. The chamfered structure can be provided on both the inner and outer peripheral walls.
[0058] To sum up, the convenient installation device for water supply pipes provided by the utility model provides a basis for supporting and connecting the ports of two water supply pipes 010 through the inner connecting tube 100, and the inner diameter of the channel 120 on the inner connecting tube 100 is consistent with the inner diameter of the water supply pipe 010, so that the influence of the inner connecting tube 100 on the flow field inside the water supply pipe 010 is reduced as much as possible; the outward expansion action of the water supply pipe 010 is realized by the outward expansion component 200, thereby facilitating the installation process of the inner connecting tube 100; the outer wall of the inner connecting tube 100 and the inner wall of the outer connecting tube 300 clamp the water supply pipe 010, achieving a fixed connection while providing a sealing effect, and the groove 111 of the inner connecting tube 100 corresponds to the convex ring of the outer connecting tube 300, thereby improving the fixing effect and the sealing effect; the convenient installation device for water supply pipes 010 simplifies the connection process of the water supply pipe 010, improves the connection strength, improves the sealing performance and improves the maintainability.
