Description

Technical Field

[0001] This utility model relates to the field of sealing joint design technology, and in particular to a quick-connect sealing joint for quick-release valves. Background Technology

[0002] A quick-release valve is a device used to control fluid flow. It generally consists of a valve body, a valve core, and seals. When compressed air enters through the inlet, the gas pressure acts on one side of the valve core. When this pressure overcomes the resistance on the other side of the valve core, the valve core moves, thereby opening the fluid passage and allowing gas to pass through the valve quickly, thus achieving rapid exhaust or other fluid transfer functions.

[0003] The quick-connect sealing joint for quick-exhaust valves enables efficient connection, prevents leakage, and is compatible with various pipelines and equipment. Traditional quick-connect sealing joints are prone to wear leading to leakage, have limited pressure resistance, require high connection accuracy, and have poor adaptability. To meet the rapid sealing requirements of modern quick-exhaust valves, a new type of quick-connect sealing joint for quick-exhaust valves is used.

[0004] In existing technologies, it is usually necessary to perform complex operations to separate the structure of the connecting pipe, and it may also be necessary to use specific tools to assist in the operation, resulting in low efficiency in repairing or replacing the joint. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quick-connect sealing joint for quick-release valves, which aims to improve the problem of low work efficiency in repairing or replacing joints, which usually requires complex operations to separate the structure of the connecting pipe and may also require the use of specific tools for auxiliary operations.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0008] Preferably, the sealing assembly includes a first connector, the upper surface of which is fixedly connected to the lower surface of the locking block, the upper surface of which is slidably connected to the outer wall of the rotating rod, and the inner wall of which is provided with a pipe.

Detailed Implementation

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a quick-connect sealing joint for a quick-exhaust valve, including a support column 1, a limit block 11 rotatably connected to the outer wall of the support column 1, a locking block 12 slidably connected to the outer wall of the support column 1, the outer wall of the limit block 11 slidably connected to the inner wall of the locking block 12, a rotating rod 13 rotatably connected to the inner wall of the locking block 12, a rotating block 14 fixedly connected to the rear outer wall of the locking block 12, a rotating shaft 15 fixedly connected to the inner wall of the rotating block 14, a fixed base 16 rotatably connected to the outer wall of the rotating shaft 15, a locking block 17 slidably connected to the outer wall of the rotating rod 13, and a sealing component provided on the lower surface of the locking block 17 to prevent air leakage at the connection between the two pipes;

[0024] Specifically, by rotating the limiting block 11 on the support column 1, the locking block 12 can be locked or unlocked. By moving the locking block 12, the rotating rod 13 is rotated, causing the rotating rod 13 to separate from the locking block 17. The locking block 12 drives the rotating block 14 to rotate, causing the rotating shaft 15 to rotate on the inner wall of the fixed base 16, thereby enabling the rotating rod 13 to engage with or disengage from the locking block 17. This component can not only quickly connect the first connector 2 and the second connector 21 to achieve a quick connection and sealing effect, but also achieve a self-locking effect.

[0025] Reference Figure 1and Figure 3 The sealing assembly includes a first connector 2, the upper surface of which is fixedly connected to the lower surface of the locking block 17, the upper surface of which is slidably connected to the outer wall of the rotating rod 13, and the inner wall of which is provided with a pipe 4; a second connector 21 is provided on the front outer wall of the first connector 2, the upper surface of which is fixedly connected to the lower surface of the support column 1, the upper surface of which is fixedly connected to the lower surface of the fixed base 16, the upper surface of which is slidably connected to the outer wall of the locking block 12, the inner wall of which is provided on the outer wall of the pipe 4, the inner wall of which is fixedly connected with a drain port 22, and the inner wall of which is provided with a filter assembly for filtering impurities in the gas;

[0026] Specifically, the first connector 2 and the second connector 21 are connected by a connecting component, so that the pipe 4 is inserted into the connector. At the same time, a filter component is set on the inner wall of the first connector 2 and the second connector 21, which can achieve the effect of filtering impurities in the gas and expelling them through the drain port 22.

[0027] Reference Figure 4 The filter assembly includes a limiting ring 3, the outer wall of which is fixedly connected to the inner wall of the second connector 21 and the inner wall of the first connector 2. A limiting groove 31 is formed in the inner wall of the limiting ring 3. A rotating ring 32 is rotatably connected to the inner wall of the limiting ring 3, and the outer wall of the rotating ring 32 is rotatably connected to the inner wall of the limiting groove 31. A blade 33 is provided on the inner wall of the rotating ring 32. A connecting rod 34 is fixedly connected to the inner wall of the rotating ring 32, and a rotating column 35 is fixedly connected to the outer wall of the connecting rod 34. A filter plate 36 is rotatably connected to the outer wall of the rotating column 35. The outer wall of the filter plate 36 is fixedly connected to the inner wall of the first connector 2 and the inner wall of the second connector 21. A scraper 37 is slidably connected to the right outer wall of the filter plate 36, and the outer wall of the scraper 37 is fixedly connected to the inner wall of the rotating column 35.

[0028] Specifically, the gas drives the blade 33 to move, causing the rotating ring 32 to rotate on the inner wall of the limiting groove 31 opened in the limiting ring 3. The rotating ring 32 drives the connecting rod 34 to rotate, causing the rotating column 35 to rotate. The rotating column 35 drives the scraper 37 to rotate, enabling the scraper 37 to slide on the outer wall of the filter plate 36. This component can not only achieve the effect of filtering impurities in the gas, but also achieve the effect of automatically cleaning the filter residue on the filter plate 36.

[0029] Working principle: When the connector is needed, the limiting block 11 on the support column 1 is rotated to unlock it vertically. The locking block 12 is lifted, causing the rotating rod 13 to move and disengage from the locking block 17. The locking block 12 is then lifted upwards, simultaneously causing the rotating block 14 to rotate, making the rotating shaft 15 rotate against the inner wall of the fixed base 16. Then, the rotating rod 13 is lifted, achieving the effect of quickly separating the first connector 2 and the second connector 21. After replacement, the rotating rod 13 and locking block 12 are lowered, causing the locking block 12 to move and rotate the rotating block 14, making the rotating shaft 15 rotate. When the locking block 12 is fully lowered, the limiting block 11 is rotated to lock the locking block 12. This assembly not only quickly connects the first connector 2 and the second connector 21 to achieve a quick connection and sealing effect, but also achieves a self-locking effect. Gas flows through the pipe 4 to the first connector... In the first connector 2 and the second connector 21, the gas drives the blade 33 to move, causing the rotating ring 32 to rotate in the limiting groove 31 opened in the limiting ring 3. The rotation of the rotating ring 32 drives the connecting rod 34 to rotate, causing the rotating column 35 to rotate. The rotation of the rotating column 35 drives the scraper 37 to slide on the outer right side of the filter plate 36. By closing the pipe 4 on the other side and opening the drain port 22, the gas carries impurities out of the connector. This component can not only achieve the effect of filtering impurities in the gas, but also achieve the effect of automatically cleaning the filter residue on the filter plate 36. This connector not only solves the problem that in the prior art, it usually requires complicated operations to separate the structure of the connecting pipe 4, and may also require the use of specific tools for auxiliary operations, resulting in low work efficiency for repairing or replacing the connector, but also solves the problem that the flowing gas contains impurities and it is inconvenient to clean the filter plate 36.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
