Description

Technical Field

[0001] This utility model relates to the field of union technology, and in particular to an I-shaped union. Background Technology

[0002] As a key component widely used in pipeline connection systems, unions enable convenient connection and disassembly between two pipelines. In many industrial and civil fields, unions play a vital role. Their ingenious design makes pipeline installation, maintenance, and system layout adjustment more efficient, saving manpower and resources and significantly shortening the project cycle.

[0003] The I-shaped union stands out for its simple yet unique straight-line structure. It is mainly used in applications requiring straight pipe connections and demanding a certain level of sealing and stability. In the cooling water pipes of some precision instruments or the direct water supply lines in home kitchens and bathrooms, the I-shaped union can accurately connect pipes, ensuring a smooth water flow. At the same time, due to its compact structure, it can be easily installed in limited spaces, effectively avoiding water pressure loss and poor water flow caused by pipe bends.

[0004] Currently, the I-shaped unions on the market are made of ordinary metal materials, which result in poor corrosion resistance. In humid or chemically corrosive environments, they are prone to rust and corrosion, which in turn affects the sealing performance of the pipeline. In existing technology, sealing gaskets are installed at the connection to seal it. However, in long-term use, the elasticity of the sealing gaskets decreases over time, and they are difficult to fully rebound after being subjected to pressure for a long time, resulting in poor sealing. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an I-shaped union, which aims to improve the problem in the prior art where the elasticity of the sealing gasket decreases over time during long-term use, and it is difficult to fully rebound after being subjected to pressure for a long time, resulting in poor sealing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an I-shaped union, comprising a union tube, a nut fixedly connected to the front side of the outer wall of the union tube, a connecting thread fixedly connected to the rear side of the union tube, a connecting tube threaded to the outer wall of the connecting thread, a ring fixedly connected to the rear side of the outer wall of the union tube, a circular groove formed on the front side of the ring, a sealing ring fixedly connected to the front side of the outer wall of the connecting tube, a limiting ring fixedly connected to the outer wall of the ring, a plurality of limiting bolts rotatably connected to the outer wall of the limiting ring at equal intervals, and an installation mechanism provided at the rear end of the connecting tube for connecting a water pipe.

[0007] As a further description of the above technical solution:

[0008] The installation mechanism includes multiple buckles. Multiple buckles are fixedly connected at equal intervals on the rear side of the connecting pipe. Limiting posts are slidably connected to the outer walls of the multiple buckles. A connecting ring is provided on the rear side of the connecting pipe. Multiple slots are provided at equal intervals on the front side of the connecting ring. Multiple reserved holes are provided at equal intervals on the front side of the outer walls of the multiple connecting rings.

[0009] As a further description of the above technical solution:

[0010] The rear side of the connecting ring is fixedly connected with multiple fastening threads at equal intervals, and the outer walls of the multiple fastening threads are all threaded to the same fastening ring.

[0011] As a further description of the above technical solution:

[0012] A sealing gasket is fixedly connected to the front side of the fastening ring, and the front side of the sealing gasket is in contact with the rear side of the connecting ring.

[0013] As a further description of the above technical solution:

[0015] As a further description of the above technical solution:

[0016] The multiple buckles slide inside their respective slots, and the buckles and slots are matched in size.

[0020] The outer front side of the sealing ring is slidably connected to the inside of the circular groove, and the size of the sealing ring matches that of the circular groove.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the nut on the front side of the outer wall of the connector pipe is rotated and adjusted to securely connect with the external equipment. The connecting thread on the rear side and the connecting pipe thread engage to fix the two. The circular ring is inserted into the circular groove and cooperates with the sealing ring. The sealing ring is stuck into the circular groove. The limiting ring and the limiting bolt are firmly connected to achieve sealing and ensure that the pipeline system has no risk of leakage when transporting liquids or gases, and operates stably and reliably.

[0023] 2. In this utility model, by aligning the elastic buckle on the connecting pipe with the front groove of the connecting ring, it slides in along the inner wall.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of an I-shaped union, comprising a union tube 1, with a nut 3 fixedly connected to the front side of its outer wall. The nut 3 can be used to securely connect with external equipment or pipelines. By rotating it, the tightness of the connection can be adjusted to ensure that the connection will not loosen or leak. A connecting thread 4 is fixedly connected to the rear side of the union tube 1. The connecting thread 4 plays a key role, tightly engaging with the thread on the outer wall of the connecting tube 5. When connecting two pipes, the connecting tube 5 is aligned with the union tube 1 and rotated. The interaction of the threads of the two pipes causes the connecting tube 5 to gradually approach and fix, ensuring the continuity of the pipeline. A sealing ring 8 is fixedly connected to the front side of the outer wall of the connecting tube 5. The sealing ring 8 is made of rubber or other materials and can effectively fill the tiny gaps at the connection. Its front side of the outer wall slides inside the circular groove 7 opened on the front side of the ring 6. The size of the sealing ring 8 matches that of the circular groove 7, ensuring that the sealing ring 8 is accurately positioned and fills the groove. The annular gap between ring 6 and connecting pipe 5 facilitates installation and provides a continuous sealing effect to prevent liquid or gas leakage. A limiting ring 9 is fixedly connected to the outer wall of ring 6. The limiting ring 9 is used to assist in fixing the position of connecting pipe 5. Multiple limiting bolts 10 are equidistantly rotatably connected to the outer wall of limiting ring 9. While limiting the axial displacement of connecting pipe 5, the limiting bolts 10 can also assist in fixing the position of sealing ring 8 from the side. When the pipeline system is subjected to external impact or internal pressure changes, the sealing ring 8 is kept in the correct position in the groove 7 to prevent leakage. An installation mechanism 2 is provided at the rear end of connecting pipe 5. The installation mechanism 2 is used to connect water pipe. It contains multiple buckles 201. Multiple buckles 201 are equidistantly fixed to the rear side of connecting pipe 5. They can quickly and accurately engage with the slots 204 equidistantly opened on the front side of connecting ring 203. The buckles 201 slide smoothly into the slots 204 and are tightly locked to prevent shaking or loosening after connection.

[0033] Specifically, the connector pipe 1, as the main component, has a nut 3 fixed to its front outer wall for fastening connection with external equipment or pipelines. Rotating the nut 3 adjusts the tightness of the connection, ensuring no loosening or leakage. The connecting thread 4 on the rear side of the connector pipe 1 plays a crucial role, tightly engaging with the outer thread of the connecting pipe 5. When connecting two pipes, aligning the connecting pipe 5 with the connector pipe 1 and rotating it causes the connecting thread 4 and the thread of the connecting pipe 5 to interact, gradually bringing them closer together and fixing them in place, forming a stable connection and ensuring pipeline connectivity. The circular ring 6 and its front groove 7, in conjunction with the sealing ring 8, complete the sealing task. During the connection process, the sealing ring 8 on the front side of the outer wall of the connecting pipe 5 will be inserted into the circular groove 7 of the ring 6. The sealing ring 8 is usually made of materials with good elasticity and sealing performance, such as rubber, which can effectively fill the tiny gaps at the connection and prevent liquid or gas leakage. The limiting ring 9 and multiple limiting bolts 10 are used to further stabilize the connection. The limiting ring 9 is fixed to the outer wall of the ring 6. After the connecting pipe 5 and the connector pipe 1 are connected in place, the limiting bolts 10 are rotated so that their front ends press against the connecting pipe 5, limiting the axial displacement of the connecting pipe 5 and ensuring that the sealing ring 8 can be accurately positioned during installation and fill the annular gap between the ring 6 and the connecting pipe 5.

[0034] Reference Figure 4 and Figure 5The installation mechanism 2 plays a crucial role in the connection of the I-shaped union water pipe. It includes multiple clips 201, which are equidistantly fixed to the rear side of the connecting pipe 5. These clips 201, as key components for quick connection, can easily mate with the connecting ring 203 due to their structural characteristics, saving time for subsequent assembly. The outer walls of the multiple clips 201 are slidably connected to limit posts 202. After the clips 201 are initially connected, the limit posts 202 can tightly lock the position of the clips 201, preventing them from coming off due to accidental force, greatly enhancing the stability of the connection and making the entire structure more robust and reliable. The connecting ring 203 is provided on the rear side of the connecting pipe 5. The connecting ring 203 provides a basic connection framework for the entire installation mechanism 2, allowing all components to be connected around it. Working together, the front side of the connecting ring 203 has multiple slots 204 at equal intervals. The slots 204 are precisely matched with the buckles 201, which can guide the buckles 201 to slide in accurately and achieve a tight fit between the two, ensuring the accuracy of the connection. The front side of the outer wall of the multiple connecting rings 203 has multiple reserved holes 205 at equal intervals. The reserved holes 205 provide convenient conditions for subsequent expansion installation. For example, bolts and other connecting parts can be inserted according to actual needs to meet diverse installation scenarios. The multiple buckles 201 slide into the corresponding slots 204 respectively. The size of the buckles 201 and the slots 204 are matched. This precise matching not only ensures that the buckles 201 can slide into the slots 204 smoothly, but also that they can fit tightly after sliding in, eliminating the risk of loosening after connection, so that the connecting pipe 5 and the connecting ring 203 form a stable whole.

[0035] Specifically, when assembling the connecting pipe 5 with other corresponding components, the connecting ring 203 is prepared, with multiple slots 204 evenly spaced on its front side that fit into the buckles 201. During operation, the end of the connecting pipe 5 with the buckle 201 is aligned with the connecting ring 203, allowing the buckle 201 to slide along the inner wall of the connecting ring 203 into the slot 204. Because the buckle 201 has a certain elastic deformation capacity, it will deform moderately during the sliding process. After being fully engaged in the slot 204, the buckle 201... 1. Restore the original state to tightly lock the connecting ring 203, ensuring a stable connection between the two and improving assembly efficiency. The limiting post 202 plays an important auxiliary fixing role, slidingly connecting with the outer wall of the buckle 201. After the buckle 201 is inserted into the slot 204, the limiting post 202 can prevent the buckle 201 from accidentally coming out, further enhancing the reliability of the connection and ensuring the rapid docking of the connecting pipe 5 and the connecting ring 203 during the installation process. The buckle 201 can smoothly slide into the slot 204 and be tightly locked.

[0036] Reference Figure 2 , Figure 3 and Figure 4The connecting ring 203 and the fastening threads 11 are like multiple fine fastening threads 11, all of which are threaded to the same fastening ring 12. The fastening ring 12 can rotate and move flexibly along the fastening threads 11. Through this threaded engagement, the tightness can be adjusted, and additional stabilizing force can be applied to the connection to ensure that the entire connection structure will not loosen under complex working conditions. A sealing gasket 13 is fixedly connected to the front side of the fastening ring 12. The sealing gasket 13 is made of highly elastic and wear-resistant material. The front side of the sealing gasket 13 fits against the rear side of the connecting ring 203. When the fastening ring 12 is tightened, the sealing gasket 13 is uniformly compressed, tightly filling any tiny gaps that may appear between the connecting ring 203 and the external components, effectively preventing liquid and gas leakage and ensuring the pipeline's sealing performance. Each limiting bolt 10 has a slidable gasket 14 on its outer wall. The gasket 14 is soft and has good cushioning performance, which can effectively disperse pressure. One side of each gasket 14 is in contact with the outer wall of the limiting ring 9. During the tightening of the limiting bolt 10, the gasket 14 prevents the limiting ring 9 from being damaged due to excessive local force, thus extending the service life of the component. One end of each limiting bolt 10 passes through the limiting ring 9, so the limiting bolt 10 can be accurately positioned and accurately play the role of limiting the displacement of the connecting pipe 5. One end of each limiting ring 9 is in contact with the outer wall of the sealing ring 8. This not only helps to fix the position of the sealing ring 8, but also prevents the sealing ring 8 from shifting when the pipeline is subjected to external force impact, continuously maintaining the sealing effect and ensuring the reliable operation of the entire I-shaped union.

[0037] Specifically, the fastening ring 12, which is connected to the threaded connection, can be rotated to move along the fastening thread 11 after installation. When the fastening ring 12 is tightened, the sealing gasket 13 is compressed, filling any small gaps that may exist between the connecting ring 203 and the external component. When the limiting bolt 10 is tightened, the pressure applied by the bolt to the limiting ring 9 is evenly distributed through the gasket 14, preventing the limiting bolt 10 from directly compressing the limiting ring 9 and causing local damage. One end of the multiple limiting bolts 10 passes through the limiting ring 9 and fits against the outer wall of the sealing ring 8. This allows the limiting bolts 10 to restrict the axial displacement of the connecting pipe 5 while also helping to fix the position of the sealing ring 8 from the side.

[0038] Working Principle: When using an I-shaped union, the union tube 1 serves as the main component. The nut 3 fixed to the front of its outer wall is used for secure connection to external equipment or pipelines. Rotating the nut 3 adjusts the tightness of the connection, ensuring no loosening or leakage. The connecting thread 4 on the rear side of the union tube 1 plays a crucial role, tightly engaging with the outer thread of the connecting tube 5. When connecting two pipes, align the connecting tube 5 with the union tube 1 and rotate it. The interaction between the connecting thread 4 and the thread of the connecting tube 5 gradually brings them closer together and secures them, forming a stable connection and ensuring the continuity of the pipeline. In general, the circular ring 6 and its front groove 7 work together with the sealing ring 8 to complete the sealing task. During the connection process, the sealing ring 8 on the front side of the outer wall of the connecting pipe 5 will be inserted into the circular groove 7 of the circular ring 6. The sealing ring 8 is usually made of materials with good elasticity and sealing performance, such as rubber, which can effectively fill the tiny gaps at the connection and prevent liquid or gas leakage. The limiting ring 9 and multiple limiting bolts 10 are used to further stabilize the connection. The limiting ring 9 is fixed to the outer wall of the circular ring 6. After the connecting pipe 5 and the connector pipe 1 are connected in place, the limiting bolts 10 are rotated so that their front ends press against the connecting pipe 5 to limit the axial displacement of the connecting pipe 5.

[0039] Furthermore, when it is necessary to assemble the connecting pipe 5 with other corresponding components, the connecting ring 203 is prepared, with multiple slots 204 equidistantly opened on its front side that are compatible with the buckle 201. During operation, the end of the connecting pipe 5 with the buckle 201 is aligned with the connecting ring 203, and the buckle 201 slides into the slot 204 along the inner wall of the connecting ring 203. Since the buckle 201 has a certain elastic deformation capability, it will undergo moderate deformation during the sliding process. After it is fully inserted into the slot 204, the buckle 201 returns to its original shape, thereby tightly locking the connecting ring 203, ensuring a stable connection between the two, and improving assembly efficiency. The limiting post 202 plays an important auxiliary fixing role, slidingly connected to the outer wall of the buckle 201. After the buckle 201 is inserted into the slot 204, the limiting post 202 can prevent the buckle 201 from accidentally coming out, further enhancing the reliability of the connection.
