Abstract
Description
Technical Field
[0001] The utility model relates to a leak-proof structure, in particular to a leak-proof structure at the butt joint of water pipes. Background Technique
[0002] Leak prevention at the butt joint of water pipes refers to the techniques and methods to ensure that there is no water leakage at the connection of water pipes during the installation or maintenance of water pipes. The connections of water pipes are usually the parts most prone to problems in the entire water supply system because they are affected by multiple factors such as water pressure, temperature changes, physical stress, and material aging.
[0003] Various water pipes are frequently used in daily life for pipeline water conveyance operations. However, during the docking process of existing water pipes, the pipe interfaces are not convenient to dock, and leakage is likely to occur, which not only causes waste of water resources but also may accidentally cause significant accident losses. Therefore, a leak-proof water pipe is needed to avoid water leakage at the connection of water pipes.
[0004] Therefore, it is necessary to design a leak-proof structure at the butt joint of water pipes to solve the above technical problems. Content of the Utility Model
[0005] In order to overcome the disadvantages that the pipe interfaces are not convenient to dock and leakage is likely to occur, the technical problem to be solved is: to provide a leak-proof structure at the butt joint of water pipes.
[0006] The technical solution is: a leak-proof structure at the butt joint of water pipes, including a first water pipe, a second water pipe, a first connection ring, a second connection ring, a fixing ring, a reinforcing rib, an internal thread ring, and an external thread ring. The top of the first water pipe is fixedly connected with the first connection ring. The second water pipe is located above the first water pipe, and the bottom of the second water pipe is fixedly connected with the second connection ring. The first connection ring and the second connection ring are in contact with each other. The bottom of the first connection ring is slidably sleeved with a fixing ring. A plurality of reinforcing ribs are fixedly connected to the fixing ring in a circular array. Each reinforcing rib penetrates through the first connection ring and the second connection ring. An internal thread ring is provided inside the first connection ring, and an external thread ring is provided outside the second connection ring. The internal thread ring and the external thread ring are threadedly connected.
[0007] Furthermore, it also includes a fixing rod. The top of the first water pipe is fixedly connected with the fixing rod, and a fixing insertion hole is opened at the bottom of the second water pipe. The fixing rod is inserted into the fixing insertion hole.
[0008] Furthermore, it also includes a sealing ring and a spring. The top of the first water pipe is fixedly connected with the sealing ring. A groove for placing the spring is opened inside the first water pipe. A spring is connected between the first water pipe and the sealing ring. A clamping groove is opened at the bottom of the second water pipe, and the clamping groove is in close fit with the sealing ring.
[0009] Furthermore, a plurality of anti-slip blocks are fixedly connected to the outer sides of the first connecting ring and the second connecting ring in an annular array, facilitating the rotation of the first connecting ring and the second connecting ring.
[0010] Furthermore, the sealing ring is made of soft rubber material.
[0011] Furthermore, both the first connecting ring and the second connecting ring are made of rust-proof and corrosion-proof materials.
[0012] The beneficial effects of the present utility model are as follows: 1. By screwing the first connecting ring and the second connecting ring, the fixing rod is inserted into the fixing jack, and the first water pipe and the second water pipe are hermetically connected, thus solving the problem that the pipeline interface is inconvenient to dock and is prone to leakage.
[0013] 2. Through the elastic force of the spring, the sealing ring is closely attached to the clamping groove, making the sealing more firm and further enhancing the anti-leakage effect of the structure.
[0014] 3. Through the reinforcing ribs provided on the outer sides of the first connecting ring and the second connecting ring, the butt joint of the threaded connection is protected, preventing the water pipe from being damaged at the joint due to bending, thereby improving the durability.

[0022] The following further describes the present utility model with reference to the drawings and embodiments.
[0023] Embodiment: A leak-proof structure at the water pipe joint, as Figure 1 , Figure 2 and Figure 3 shown, which includes a first water pipe 1, a second water pipe 2, a first connecting ring 3, a second connecting ring 4, a fixing ring 5, reinforcing ribs 6, an internal thread ring 7 and an external thread ring 8. The first connecting ring 3 is welded to the top of the first water pipe 1. The second water pipe 2 is located above the first water pipe 1. The second connecting ring 4 is welded to the bottom of the second water pipe 2. The first connecting ring 3 and the second connecting ring 4 are in contact with each other. Both the first connecting ring 3 and the second connecting ring 4 are made of rust-proof and corrosion-proof materials. A plurality of anti-slip blocks 14 are welded annularly and arrayed on the outer sides of the first connecting ring 3 and the second connecting ring 4, which is convenient for rotating the first connecting ring 3 and the second connecting ring 4. The fixing ring 5 is slidably sleeved on the bottom of the first connecting ring 3. A plurality of reinforcing ribs 6 are welded annularly and arrayed on the fixing ring 5. Each reinforcing rib 6 penetrates through the first connecting ring 3 and the second connecting ring 4. An internal thread ring 7 is provided inside the first connecting ring 3, and an external thread ring 8 is provided outside the second connecting ring 4. The internal thread ring 7 and the external thread ring 8 are threadedly connected.
[0024] When the staff uses this device, first, the first connecting ring 3 needs to be sleeved on the first water pipe 1, and the second connecting ring 4 is sleeved on the second water pipe 2. Then, the fixing rod 9 at the top of the first water pipe 1 is inserted into the fixing jack 10 opened at the bottom of the second water pipe 2. At this time, the internal thread ring 7 inside the first connecting pipe will contact the external thread ring 8 of the second connecting pipe. Subsequently, the second connecting ring 4 is rotated clockwise so that the first connecting ring 3 and the second connecting ring 4 are threadedly connected.
[0025] As Figure 4 , Figure 5 and Figure 6 shown, it also includes a fixing rod 9, a sealing ring 11 and a spring 12. The fixing rod 9 is welded to the top of the first water pipe 1. A fixing jack 10 is opened at the bottom of the second water pipe 2. The fixing rod 9 is inserted into the fixing jack 10. The sealing ring 11 is welded to the top of the first water pipe 1. The sealing ring 11 is made of soft rubber material. A groove for placing the spring 12 is opened inside the first water pipe 1. A spring 12 is connected between the first water pipe 1 and the sealing ring 11. A clamping groove 13 is opened at the bottom of the second water pipe 2. The clamping groove 13 is in close contact with the sealing ring 11.
[0026] When the first connecting ring 3 and the second connecting ring 4 are in close contact, at this time, the spring 12 is compressed by the sealing ring 11. The sealing ring 11 is tightly attached to the clamping groove 13 opened at the bottom of the second water pipe 2 under the elastic force of the spring 12, making the sealing more firm and further strengthening the leak-proof effect of the structure. After the sealing is completed, the fixing ring 5 can be sleeved on the bottom of the first connecting ring 3, and then the reinforcing ribs 6 are inserted into the first connecting ring 3 and the second connecting ring 4 to protect the butt joint of the threaded connection and prevent the water pipe from being damaged at the junction due to bending. If the water pipes need to be docked again, just repeat the above operations.
[0027] Those skilled in the art should understand that the above embodiments do not limit the present utility model in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present utility model.
