Description

Technical Field

[0001] This utility model relates to the field of pipe connection, specifically an anti-detachment connection mechanism for pipe connection. Background Technology

[0002] Pipe connection refers to the operation of combining two or more pipes in a specific way to form a continuous pipeline system that can transport fluids (such as liquids, gases, etc.). Pipe connection anti-detachment refers to a series of technical measures and design methods to prevent the pipe connection from loosening or falling off due to factors such as vibration, pressure changes, and external forces.

[0003] In existing technologies, when multiple pipelines are in use, they are usually connected using bolts, ferrules, flanges, etc., so that multiple pipelines can be connected to each other and used smoothly. However, some of the bolt or ferrule connections used in pipelines are prone to loosening due to rust and other reasons after long-term use. Since the connection between pipelines is only made by ferrules or bolts, when the connection between pipelines rusts, it is easy to cause significant loosening, resulting in failure to use smoothly, disconnection between pipelines, and fluid leakage. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, some pipes use bolts or ferrules for connection, which are prone to loosening due to rust and other reasons after long-term use. Since the connection between pipes is only made by ferrules or bolts, when the connection between pipes rusts, it is easy to loosen and cause problems such as failure to use smoothly, separation of pipes from each other, and fluid leakage. This utility model proposes an anti-detachment connection mechanism for pipe connections.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a pipe connection anti-detachment connection mechanism, including a first pipe, a second pipe provided at one end of the first pipe, and an auxiliary mechanism and an anti-detachment mechanism provided on the surface of the first pipe and the second pipe.

[0006] The anti-detachment mechanism includes a fixing block, one side of which is fixedly connected to the surface of the first pipe, and a connecting block is fixedly connected to the surface of the second pipe. One side of the fixing block is movably inserted into the inner cavity of the connecting block. A sliding sleeve is slidably connected to the surface of the connecting block. A slot is provided on one side of the fixing block. A limiting block is movably inserted into the inner cavity of the connecting block. One side of the limiting block is movably inserted into the inner cavity of the slot.

[0007] Preferably, the auxiliary mechanism includes a first fixing ring block, the inner cavity of the first fixing ring block being rotatably connected to the surface of the first pipe, a second fixing ring block being fixedly connected to the surface of the second pipe, a first insert block and a first buckle being fixedly connected to the surface of the first fixing ring block, and a second buckle and a second insert block being fixedly connected to the surface of the second fixing ring block, wherein the first buckle and the second buckle are the same size, and the second insert block is the same size as the first insert block.

[0008] Preferably, a fixing plate is fixedly connected to one side of the connecting block, a spring is fixedly connected to one side of the fixing plate, a moving block is fixedly connected to one end of the spring, and one side of the moving block is fixedly connected to the surface of the sliding sleeve.

[0009] Preferably, a limiting rod is fixedly connected to one side of the fixed plate, the surface of the limiting rod is slidably connected to the inner cavity of the moving block, and a limiting ring block is fixedly connected to one end of the limiting rod.

[0010] Preferably, the inner cavity of the connecting block is provided with a limiting groove, and a limiting block is fixedly connected to one side of the limiting block, with the surface of the limiting block slidably connected to the inner cavity of the limiting groove.

[0011] Preferably, the inner cavity of the connecting block is fixedly connected to a plug rod, and a limiting groove is formed on one side of the fixed block, and the surface of the plug rod is movably inserted into the inner cavity of the limiting groove.

[0012] Preferably, both the first and second fixed ring blocks are fixedly connected to a connecting plate, and the inner cavities of the two connecting plates are threaded with fastening bolts.

[0013] The advantages of this utility model are:

[0014] This invention achieves a basic connection between the first and second pipes by smoothly inserting the fixing block into the connecting block. Then, the sliding sleeve restricts the limiting block, and after the first fixing ring block rotates to a certain angle, the first buckle connects with the first and second insert blocks, and the second buckle connects with the first and second insert blocks. This installation and reinforcement of the first and second pipes ensures that, after long-term use, the first and second pipes are less prone to significant loosening or separation due to rust. This increases the stability and firmness of the first and second pipes during use. It solves the problems of bolt or clamp connections used in some pipe systems, which are prone to loosening due to rust after long-term use. Furthermore, because pipe connections rely solely on clamps or bolts, rust can easily cause significant loosening, leading to unusable conditions or fluid leaks. Attached Figure Description

Detailed Implementation

[0023] 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 scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses an anti-detachment connection mechanism for pipe connections. (Refer to...) Figure 1 and Figure 4 A pipe connection anti-detachment connection mechanism includes a first pipe 1, a second pipe 2 provided at one end of the first pipe 1, and an auxiliary mechanism 3 and an anti-detachment mechanism 4 provided on the surfaces of the first pipe 1 and the second pipe 2.

[0026] The anti-detachment mechanism 4 includes a fixing block 401. One side of the fixing block 401 is fixedly connected to the surface of the first pipe 1. A connecting block 402 is fixedly connected to the surface of the second pipe 2. One side of the fixing block 401 is movably inserted into the inner cavity of the connecting block 402. A sliding sleeve 403 is slidably connected to the surface of the connecting block 402. A slot 404 is provided on one side of the fixing block 401. A limiting block 405 is movably inserted into the inner cavity of the connecting block 402. One side of the limiting block 405 is movably inserted into the inner cavity of the slot 404.

[0027] The first pipe 1 and the second pipe 2 can be connected to each other through the auxiliary mechanism 3 and the anti-detachment mechanism 4. The auxiliary mechanism 3 and the anti-detachment mechanism 4 can cooperate with each other to ensure that the connection between the first pipe 1 and the second pipe 2 remains firm after long-term use. The first pipe 1 can install the fixing block 401, while the second pipe 2 can fix the connecting block 402. When the first pipe 1 is connected to the second pipe 2, the fixing block 401 will be inserted into the interior of the connecting block 402. The two sides of the limiting block 405 are both set with slopes, which allows the fixing block 401 to push the limiting block 405 smoothly when it is inserted into the interior of the connecting block 402. The sliding sleeve 403 on the surface of the connecting block 402 can also push the limiting block 405 after sliding to a certain distance, so that the limiting block 405 can be smoothly inserted into the interior of the slot 404. Then, the slot 404 is restricted by the limiting block 405, and the connection between the fixing block 401 and the connecting block 402 is completed.

[0028] Reference Figure 3 and Figure 5 The auxiliary mechanism 3 includes a first fixing ring block 301. The inner cavity of the first fixing ring block 301 is rotatably connected to the surface of the first pipe 1. A second fixing ring block 302 is fixedly connected to the surface of the second pipe 2. A first insert block 303 and a first buckle 304 are fixedly connected to the surface of the first fixing ring block 301. A second buckle 305 and a second insert block 306 are fixedly connected to the surface of the second fixing ring block 302. The first buckle 304 and the second buckle 305 are the same size. The second insert block 306 is the same size as the first insert block 303. The first fixing ring block 301 can connect the first insert block 303 and the first buckle 304, while the second fixing ring block 302 can install the second buckle 305 and the second insert block 306.

[0029] Furthermore, after the first pipe 1 and the second pipe 2 are connected to each other through the anti-detachment mechanism 4, the first fixing ring block 301 can be rotated smoothly. When the first fixing ring block 301 is rotated, it can smoothly drive the second fixing ring block 302 and the first buckle 304 to rotate. After the second fixing ring block 302 rotates to a certain distance, it will be inserted into the inside of the second buckle 305, and the first buckle 304 will also be smoothly inserted into the outside of the second insert block 306. At this time, the cooperation between the first buckle 304 and the second buckle 305 can effectively strengthen the connection between the first pipe 1 and the second pipe 2, thereby achieving a certain anti-detachment effect.

[0030] Reference Figure 3 and Figure 4 A fixing plate 9 is fixedly connected to one side of the connecting block 402, and a spring 10 is fixedly connected to one side of the fixing plate 9. A moving block 11 is fixedly connected to one end of the spring 10. One side of the moving block 11 is fixedly connected to the surface of the sliding sleeve 403. The fixing plate 9 can connect the moving block 11 through the spring 10. The connection between the moving block 11 and the sliding sleeve 403 allows the sliding sleeve 403 to be reset by the elasticity of the spring 10 after the operator pushes it, thereby increasing the convenience of the sliding sleeve 403 in use.

[0031] Reference Figure 4 The inner cavity of the connecting block 402 is provided with a limiting groove 7. A limiting block 8 is fixedly connected to one side of the limiting block 405. The surface of the limiting block 8 is slidably connected to the inner cavity of the limiting groove 7. The opening of the limiting groove 7 enables the use of the limiting block 8. The cooperation between the limiting groove 7 and the limiting block 8 can effectively limit the movement and sliding of the limiting block 405, so that when it slides inside the connecting block 402, it is not easy for it to slide out of the connecting block 402 due to a large sliding distance.

[0032] Reference Figure 3 and Figure 4 A limiting rod 12 is fixedly connected to one side of the fixed plate 9. The surface of the limiting rod 12 is slidably connected to the inner cavity of the moving block 11. A limiting ring block 13 is fixedly connected to one end of the limiting rod 12. The fixed plate 9 can realize the installation and use of the limiting rod 12. The limiting rod 12 can not only limit the sliding of the moving block 11, but also reduce the possibility of deformation and bending of the spring 10 during extension and retraction. At the same time, it can also realize the connection of the limiting ring block 13. The limiting ring block 13 can effectively limit the sliding of the moving block 11, so that when the moving block 11 and the sliding sleeve 403 are reset and moved by the elasticity of the spring 10, it is not easy for the limiting block 405 to fail to be successfully limited due to the large distance of movement.

[0033] Reference Figure 4The inner cavity of the connecting block 402 is fixedly connected with the insertion rod 5. A limiting groove 6 is opened on one side of the fixing block 401. The surface of the insertion rod 5 is movably inserted into the inner cavity of the limiting groove 6. The insertion rod 5 can play a certain limiting role on the fixing block 401 through the limiting groove 6, which not only makes the fixing block 401 easier to insert into the interior of the connecting block 402, but also makes the fixing block 401 stable enough inside the connecting block 402, and it is not easy to shake or other situations.

[0034] Reference Figure 1 The surfaces of the first fixing ring block 301 and the second fixing ring block 302 are both fixedly connected with connecting plates 14. The inner cavities of the two connecting plates 14 are threaded with fastening bolts 15. The connection plates 14 and fastening bolts 15 can strengthen and tighten the connection between the first pipe 1 and the second pipe 2, so that the first pipe 1 and the second pipe 2 can be used smoothly and stably.

[0035] Working Principle: When using this device, the operator can connect the first pipe 1 and the second pipe 2. Before connection, the sliding sleeve 403 is slid towards the side closer to the fixed plate 9. After sliding, the fixed block 401 is smoothly inserted into the connecting block 402. After the fixed block 401 is inserted into the connecting block 402, it will push the limiting block 405, causing it to slide outwards from the connecting block 402. After the fixed block 401 and the connecting block 402 are fully connected, the operator can release the sliding sleeve 403. At this time, the sliding sleeve 403 will be reset by the elasticity of the spring 10, and during the reset process, it will push the limiting block 405 back into the connecting block 9. The first fixing ring block 301 is inserted into the inside of the first fixing ring block 302 and then into the inside of the slot 404 during sliding, thereby restricting the fixing block 401. After that, the operator can rotate the first fixing ring block 301. When the first fixing ring block 301 is rotated, it will smoothly drive the first buckle 304 and the first insert block 303 to rotate together. When the first buckle 304 and the first insert block 305 are rotated to a certain angle, the first insert block 303 will be inserted into the inside of the second buckle 305, and the first buckle 304 will be inserted into the surface of the second insert block 306, thereby realizing the use of the auxiliary mechanism 3. Finally, the operator can connect the fastening bolt 15 to the inside of the connecting plate 14 to successfully complete the connection and installation between the first pipe 1 and the second pipe 2.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
