Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to a pipeline connection anti-loosening structure. Background Technology

[0002] Pipeline connections are the weakest link in a pipeline system and must be effectively prevented from loosening to ensure safe and stable operation. When pipeline connections become loose, it may lead to the leakage of flammable, explosive, or toxic media, causing fires, explosions, and poisoning accidents. Under high pressure or external forces, the pipeline may even completely detach, causing serious physical damage. Connection failure can also lead to system downtime and significant economic losses. At the same time, because pipeline systems are often subjected to vibration and pressure shocks, these dynamic loads will continuously weaken the connection structure and increase the risk of loosening. Frequent maintenance also significantly increases operating costs. However, existing pipe connection anti-loosening structures use traditional threaded connections, which are insufficient in terms of anti-loosening effect and reliability. In addition, conventional clamps have the risk of uneven tightening and bolt self-loosening. In terms of installation, flange connection procedures are cumbersome, welding requirements are high and they are non-detachable connections. Many special anti-loosening structures are also too complicated, resulting in low installation efficiency. The whole system relies on a single anti-loosening principle and lacks multiple insurances after the failure of the main mechanism, thus limiting overall reliability. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies and provide a pipe connection anti-loosening structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a pipeline connection anti-loosening structure, including a locking mechanism, the locking mechanism including a fixed column, an adjusting ring provided at one end of the fixed column, an upper limit plate provided at the end of the adjusting ring away from the fixed column, a lower limit plate provided at the end of the upper limit plate away from the adjusting ring, an adjusting column provided inside the fixed column, a snap-fit ​​column provided on the side of the adjusting column near the lower limit plate, a spring provided at the end of the adjusting column away from the adjusting ring, and one side of the upper limit plate connected to the main body mechanism.

[0005] In a preferred embodiment, the main body mechanism includes an upper fixing ring, a rotating shaft at one end of the upper fixing ring, a lower fixing ring at the end of the rotating shaft away from the upper fixing ring, the end of the lower fixing ring away from the rotating shaft being connected to a lower limiting plate, and the end of the upper fixing ring away from the rotating shaft being connected to an upper limiting plate.

[0006] In a preferred embodiment, the lower limiting plate has an irregularly shaped limiting groove at one end near the upper limiting plate.

[0009] In a preferred embodiment, the adjusting column has a telescopic groove on the side near the locking column, and the locking column is disposed inside the telescopic groove.

[0010] In a preferred embodiment, a lower limit plate is provided at the end of the upper limit plate away from the adjusting ring, and the upper limit plate and the lower limit plate are engaged and locked together.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1.

[0017] 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. Example

[0018] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a pipe connection anti-loosening structure, including a locking mechanism 2. The locking mechanism 2 includes a fixing post 21, an adjusting ring 23 is provided at one end of the fixing post 21, the fixing post 21 and the adjusting ring 23 are threadedly connected, an upper limit plate 24 is provided at the end of the adjusting ring 23 away from the fixing post 21, and a lower limit plate 25 is provided at the end of the upper limit plate 24 away from the adjusting ring 23. The upper limit plate 24 and the lower limit plate 25 are engaged and locked, and the lower limit plate 25 has an opening at the end near the upper limit plate 24. There is an irregularly shaped limiting groove 201. An adjusting column 22 is set inside the fixed column 21. The adjusting column 22 is provided with a locking column 26 on both sides near the lower limiting plate 25. A columnar groove is provided near the locking column 26 of the adjusting column 22. The locking column 26 is symmetrically distributed about the adjusting column 22. A telescopic groove 203 is opened on the side of the adjusting column 22 near the locking column 26. The locking column 26 is set inside the telescopic groove 203. A spring 27 is provided at the end of the adjusting column 22 away from the adjusting ring 23. The upper limiting plate 24 is connected to the main body mechanism 1.

[0019] In this embodiment, after the upper limit plate 24 and the lower limit plate 25 are engaged, pressing the adjusting column 22 causes it to move downwards, which in turn moves the connected locking column 26 downwards. At this time, the locking column 26 retracts inwards into the telescopic groove 203. Then, the fixing column 21 passes through the upper limit plate 24 and the lower limit plate 25. After the locking column 26 has completely passed through the lower limit plate 25, the adjusting column 22 is released. Under the action of the spring 27, the adjusting column 22 moves upwards, and the locking column 26 extends out of the telescopic groove 203, achieving the engagement effect between the lower limit plate 25 and the locking column 26. Then, the adjusting ring 23 is rotated to further strengthen the tightness between the upper limit plate 24, the lower limit plate 25, and the locking column 26. The installation process is simple, greatly reducing the installation difficulty and time cost, and facilitating pipeline maintenance. Example

[0021] In this embodiment, the upper fixing ring 11 and the lower fixing ring 12 are connected by a rotating shaft 13 to realize the opening and closing of the upper fixing ring 11 and the lower fixing ring 12, which facilitates the installation of the device at the pipe connection. The snap-fit ​​groove 202 opened inside the upper fixing ring 11 and the lower fixing ring 12 is used to snap the pipe wall at the pipe connection with the inside of the main body 1, improve the snap-fit ​​effect of the device, make the pipe connection tightly snapped, and increase the friction between the device and the pipe wall.
