Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum tube structure technology, and in particular to an integrated three-way aluminum tube structure. Background Technology
[0002] Pipe fittings are a general term for connectors that can be installed and disassembled in fluid passages. They mainly include welded, compression fitting, and flared fittings. In the existing aluminum pipe fitting structure, the pipe end is exposed when not in use, and the aluminum pipe body is easily scratched, resulting in scratches. In addition, floating impurities can easily enter the pipe body. Therefore, there is a need for a tee aluminum pipe with a built-in protective sleeve.
[0003] For example, Chinese utility model patent (CN209196377U) discloses a three-way aluminum pipe connector, which states: "It includes: a first pipe body, a second pipe body and a sheath, the two ends of the first pipe body are respectively provided with a first end and a second end, one end of the second pipe body is provided with a third end and the other end is connected to the first pipe body, and the sheath is connected to the first pipe body and sleeved on the third end."
[0004] Although the aforementioned aluminum tube provides protection at the ends, the disassembly of the sheath and the plug is inconvenient when it is necessary to remove the plug from the tube body. In addition, the use of a large number of flexible materials to connect the sheath makes it easy for the sheath to shift after installation, which may lead to the risk of it falling off. Therefore, this application proposes an integrated three-way aluminum tube structure. Utility Model Content
[0005] Based on this, it is necessary to provide an integrated three-way aluminum tube structure to address the aforementioned technical problems. Through the overall structural design, when the rotating hollow screw cylinder moves the sealing plug to the inside of the three-way aluminum tube body and seals the body, tightening the hollow screw cylinder and utilizing the high friction between the hollow screw cylinder and the retaining ring, and between the hollow screw cylinder and the wrapping support sleeve, achieves better stability for the sealing plug. This provides long-term and stable protection for the three-way aluminum tube body. Furthermore, when it is necessary to remove the sealing plug, simply use the anti-slip sleeve to grip and rotate the hollow screw cylinder in the opposite direction to move the sealing plug out from the inside of the three-way aluminum tube body. Then, the outer support frame can be flipped around the support shaft to complete the disassembly, facilitating subsequent connection of the three-way aluminum tube body to external pipelines.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] An integrated tee aluminum pipe structure, used for pipe connection;
[0008] The device includes a three-way aluminum tube body. A retaining ring and a limiting ring are fixed to the outer side of one end of the three-way aluminum tube body. A port sealing sleeve is fitted to the outer side of the other end of the three-way aluminum tube body. A hollow screw cylinder is provided between the retaining ring and the limiting ring and located on the outer side of the three-way aluminum tube body. The inner side of the hollow screw cylinder is threaded to the outer side of the three-way aluminum tube body. A mounting ring is rotatably connected to the end of the hollow screw cylinder away from the retaining ring and located on the outer side of the three-way aluminum tube body. Support shafts are symmetrically fixed to the outer side of the mounting ring. An outer support frame is rotatably connected between the two support shafts and located on the outer side of the mounting ring. A sealing plug is fixed to the inner side of the outer support frame away from the retaining ring. The sealing plug is located on the inner side of the three-way aluminum tube body and fits against the three-way aluminum tube body.
[0009] In a preferred embodiment of the integrated three-way aluminum tube structure provided by this utility model, a wrapping support is fixed to the outer side of the retaining ring, and the outer side of the hollow screw cylinder is in contact with the inner side of the wrapping support.
[0010] As a preferred embodiment of the integrated three-way aluminum tube structure provided by this utility model, an anti-slip sleeve is also fixed on the outer side of the hollow screw cylinder.
[0011] As a preferred embodiment of the integrated three-way aluminum tube structure provided by this utility model, protective semi-circular sleeves are fixed at both the upper and lower ends of the outer support frame.
[0012] In a preferred embodiment of the integrated three-way aluminum tube structure provided by this utility model, the anti-slip sleeve, the protective semi-circular sleeve, and the wrapping support sleeve are all made of soft rubber.
[0013] As a preferred embodiment of the integrated three-way aluminum tube structure provided by this utility model, an elastic band is fixed at one end of the port sealing sleeve near the retaining ring, and the elastic band is located on the outside of the three-way aluminum tube body and fits against the three-way aluminum tube body.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] The integrated three-way aluminum tube structure provided by this utility model, through the overall structural design, allows the sealing plug to be moved to the inside of the three-way aluminum tube body and sealed after the rotating hollow screw cylinder moves to move it. The high friction between the hollow screw cylinder and the retaining ring, and between the hollow screw cylinder and the wrapping support sleeve, is used to fix the sealing plug. This makes it more robust than using a flexible material structure to fix the sealing plug, thus achieving long-term and stable protection for the three-way aluminum tube body.
[0016] Furthermore, when it is necessary to remove the sealing plug, simply use the anti-slip sleeve to manually grab it and rotate the hollow screw in the opposite direction to move the sealing plug out from the inside of the T-shaped aluminum pipe body. Then, the outer support frame can be flipped around the support shaft to complete the disassembly, which facilitates the subsequent connection of the T-shaped aluminum pipe body to the external pipeline.
[0017] Furthermore, when the sealing plug is located inside the body of the T-shaped aluminum tube, the hollow screw, the mounting ring, and the two protective semi-circular sleeves protect the outer side of the end of the T-shaped aluminum tube body, effectively reducing scratches caused by friction. At the same time, the elasticity of the elastic band facilitates flexible flaring and drives the port sealing sleeve to be fitted onto the outside of the T-shaped aluminum tube body to protect it.

[0025] As described in the background art, although the aluminum tubes mentioned above provide protection for the ends, it is inconvenient to disassemble the sheath and the plug when it is necessary to remove the plug from the tube body. At the same time, the use of a large number of flexible material structures to connect the sheath makes it easy for the sheath to shift after installation, which may lead to the risk of it falling off.
[0026] To solve this technical problem, this utility model provides an integrated three-way aluminum pipe structure, which is used for pipe connection;
[0027] The device includes a three-way aluminum tube body 1. A retaining ring 2 and a limiting ring 3 are fixed to the outer side of one end of the three-way aluminum tube body 1. A port sealing sleeve 13 is sleeved on the outer side of the other end of the three-way aluminum tube body 1. A hollow screw cylinder 4 is provided between the retaining ring 2 and the limiting ring 3 and located on the outer side of the three-way aluminum tube body 1. The inner side of the hollow screw cylinder 4 is threaded to the outer side of the three-way aluminum tube body 1. A mounting ring 5 is rotatably connected to the end of the hollow screw cylinder 4 away from the retaining ring 2 and located on the outer side of the three-way aluminum tube body 1. A support shaft 6 is symmetrically fixed to the outer side of the mounting ring 5. An outer support frame 7 is rotatably connected between the two support shafts 6 and located on the outer side of the mounting ring 5. A sealing plug 8 is fixed to the inner side of the outer support frame 7 away from the retaining ring 2. The sealing plug 8 is located on the inner side of the three-way aluminum tube body 1 and fits against the three-way aluminum tube body 1.
[0028] The integrated three-way aluminum tube structure provided by this utility model uses the high friction between the hollow screw cylinder 4 and the retaining ring 2 to fix the sealing plug 8, which is more robust than fixing the sealing plug 8 with a flexible material structure, thus achieving long-term and stable protection for the three-way aluminum tube body 1. When it is necessary to remove the sealing plug 8, it is only necessary to manually grasp and rotate the hollow screw cylinder 4 in the opposite direction to move the sealing plug 8 out from the inside of the three-way aluminum tube body 1. Then, the outer support frame 7 can be flipped around the support shaft 6 to complete the disassembly, which is convenient for subsequent use of the three-way aluminum tube body 1 to connect with external pipelines.
[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0031] Example 1:
[0032] Please refer to Figure 1-4An integrated three-way aluminum tube structure includes a three-way aluminum tube body 1. To facilitate sealing and protecting the ports at both ends of the three-way aluminum tube body 1, thereby effectively reducing the entry of floating impurities and reducing scratches caused by friction, a retaining ring 2 and a limiting ring 3 are fixed to the outer side of one end of the three-way aluminum tube body 1, and a port sealing sleeve 13 is sleeved on the outer side of the other end of the three-way aluminum tube body 1. A hollow screw cylinder 4 is provided between the retaining ring 2 and the limiting ring 3 and located on the outer side of the three-way aluminum tube body 1. A mounting ring 5 is rotatably connected to the end of the hollow screw cylinder 4 away from the retaining ring 2 and located on the outer side of the three-way aluminum tube body 1. Support shafts 6 are symmetrically fixed to the outer side of the mounting ring 5. An outer bearing frame 7 is rotatably connected between the two support shafts 6 and located on the outer side of the mounting ring 5. A sealing plug 8 is fixed to the inner side of the outer bearing frame 7 away from the retaining ring 2. The sealing plug 8 is located on the inner side of the three-way aluminum tube body 1 and fits against the three-way aluminum tube body 1.
[0033] To facilitate the installation and removal of the sealing plug 8, the inner side of the hollow screw cylinder 4 is threaded to the outer side of the three-way aluminum pipe body 1. Rotating the hollow screw cylinder 4 will push the mounting ring 5 to move, allowing the sealing plug 8 to enter and exit the inner side of the three-way aluminum pipe body 1. The rotational connection between the hollow screw cylinder 4 and the mounting ring 5 ensures that the mounting ring 5 does not rotate when the hollow screw cylinder 4 rotates. After the sealing plug 8 enters the inner side of the three-way aluminum pipe body 1 and seals it, the hollow screw cylinder 4 is tightened, and the high friction between the hollow screw cylinder 4 and the retaining ring 2 is used to firmly fix the sealing plug 8. When it is necessary to remove the sealing plug 8, simply grab it manually and rotate the hollow screw cylinder 4 in the opposite direction to move the sealing plug 8 out from the inner side of the three-way aluminum pipe body 1. Then, the outer support frame 7 can be flipped around the support shaft 6 to complete the disassembly, which facilitates the subsequent connection of the three-way aluminum pipe body 1 with external pipelines.
[0034] Example 2:
[0035] The integrated three-way aluminum tube structure provided in Example 1 is further optimized, specifically, as follows: Figure 1-4 As shown, when the hollow screw cylinder 4 is tightened, in order to further increase the friction between the retaining ring 2 and the hollow screw cylinder 4, thereby further improving the firmness of the sealing plug 8, a wrapping support 11 is fixed on the outer side of the retaining ring 2, and the outer side of the hollow screw cylinder 4 is tightly fitted with the inner side of the wrapping support 11. When the hollow screw cylinder 4 is manually grasped, in order to facilitate gripping and rotating the hollow screw cylinder 4, an anti-slip sleeve 9 is also fixed on the outer side of the hollow screw cylinder 4.
[0036] After the sealing plug 8 is located inside the three-way aluminum tube body 1 and seals the three-way aluminum tube body 1, in order to facilitate the protection of the outer side of the end of the three-way aluminum tube body 1 with the hollow screw 4 and the mounting ring 5, the upper and lower ends of the outer support frame 7 are fixed with protective semi-circular sleeves 10. In order to enable the anti-slip sleeve 9, the protective semi-circular sleeve 10 and the wrapping support 11 to have high friction and softness, the anti-slip sleeve 9, the protective semi-circular sleeve 10 and the wrapping support 11 are all made of soft rubber.
[0037] When the port sealing sleeve 13 is fitted onto the outside of the end of the T-shaped aluminum tube body 1, in order to facilitate the positioning and fixing of the port sealing sleeve 13, an elastic band 12 is fixed to the end of the port sealing sleeve 13 near the retaining ring 2. The elastic band 12 is located on the outside of the T-shaped aluminum tube body 1 and fits against the T-shaped aluminum tube body 1. The elasticity of the elastic band 12 makes it easy to flexibly expand or shrink the opening, thereby driving the port sealing sleeve 13 to be fitted onto the outside of the T-shaped aluminum tube body 1, so that the elastic band 12 can tightly wrap around the outside of the T-shaped aluminum tube body 1 to achieve the positioning and fixing of the port sealing sleeve 13.
