A type of ultra-high pressure anti-loosening quick coupling

Abstract

This utility model relates to the field of high-pressure connector technology and discloses an ultra-high-pressure anti-loosening quick connector, including a female connector with a male connector threadedly connected to it. Both the female and male connectors are equipped with anti-loosening mechanisms. After the female and male connectors are threadedly connected, the spring force pushes a second toothed plate forward, causing it to engage with a first toothed plate on the outer wall of the male connector, restricting the rotation of the male connector relative to the female connector. Simultaneously, a sliding rod ensures smooth movement of the second toothed plate, and a stop prevents the sliding rod from detaching from the mounting bracket. When disassembly is required, pulling the stop backward moves the sliding rod, causing the second toothed plate to compress the spring and separate from the first toothed plate, thus allowing the male connector to be unscrewed. This effectively prevents thread loosening caused by ultra-high-pressure fluid impact, avoids connector failure, and improves connection stability.

Description

Technical Field

[0001] This utility model relates to the field of high-voltage connector technology, specifically to an ultra-high-voltage anti-loosening quick connector. Background Technology

[0002] Ultra-high pressure hydraulic quick couplings, or simply ultra-high pressure quick couplings, are hydraulic connectors that allow for the connection or disconnection of pipelines in ultra-high pressure hydraulic systems without the need for additional tools. Traditional ultra-high pressure quick couplings use threaded tightening of the male and female connectors, with a one-way valve controlling the opening and closing of the connection. However, in actual working conditions, the strong impact of ultra-high pressure fluid can cause vibration in the quick coupling, loosening the threads and making the internal one-way valve prone to failure, leading to quick coupling failure. Therefore, an ultra-high pressure anti-loosening quick coupling is proposed to solve the above-mentioned problems. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an ultra-high pressure anti-loosening quick connector in view of the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an ultra-high pressure anti-loosening quick connector, including a female connector, a male connector threadedly connected to the female connector, and an anti-loosening mechanism provided on the female connector and the male connector;

[0005] The anti-loosening mechanism includes: a toothed plate and a mounting bracket. The toothed plate is connected to the outer wall of the male connector, and the mounting bracket is connected to the outer wall of the female connector. The mounting bracket is in an inverted "L" shape. A spring is connected to the inner wall of the back of the mounting bracket. A toothed plate is connected to the front end of the spring, and a sliding rod is connected to the back of the toothed plate. The outer wall of the sliding rod is slidably connected to the mounting bracket, and a stop is connected to the rear end of the sliding rod. After the female connector and the male connector are connected by threads, the toothed plate is pushed forward by the elastic force of the spring, so that it engages with the toothed plate on the outer wall of the male connector, restricting the rotation of the male connector relative to the female connector. At the same time, the sliding rod ensures that the toothed plate moves smoothly, and the stop prevents the sliding rod from disengaging from the mounting bracket. When disassembly is required, the stop is pulled backward to move the sliding rod, so that the toothed plate compresses the spring and separates from the toothed plate, thus allowing the male connector to be unscrewed. This effectively prevents the threads from loosening due to the impact of ultra-high pressure fluid, avoids connector failure, and improves connection stability.

[0006] Preferably, the first toothed plate and the second toothed plate are arranged opposite to each other, and the second toothed plate meshes with the first toothed plate. The meshing of the tooth surfaces forms a mechanical lock, which completely restricts the relative rotational freedom of the male and female connectors and enhances the anti-loosening effect.

[0007] Preferably, there are two sets of anti-loosening mechanisms, which are arranged opposite to each other on the outer wall of the female connector. They simultaneously achieve meshing of toothed plate one and toothed plate two from both sides, so that the male connector is subjected to balanced force and avoids unbalanced load caused by unilateral locking.

[0008] Preferably, the male connector is provided with a sealing mechanism, which includes an annular sealing plate connected to the left end of the male connector and inserted into the female connector. The annular sealing plate forms a physical barrier to prevent high-pressure fluid from leaking from the connector gap.

[0009] Preferably, the sealing mechanism further includes a slot, which is located at the right end of the female connector, and the annular sealing plate is inserted into the slot. The tight clearance fit restricts fluid leakage and ensures that the annular sealing plate does not shift under high pressure.

[0010] Preferably, the left end of the annular sealing plate is connected to an annular sealing gasket, and the outer wall of the annular sealing gasket abuts against the inner wall of the slot. By elastically deforming and filling the tiny gaps, zero leakage sealing under ultra-high pressure is achieved, thereby improving the safety of the joint.

[0011] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0012] 1. This ultra-high pressure anti-loosening quick connector, after the female connector and male connector are connected by threads, the toothed plate two moves forward under the elastic force of the spring, so that it engages with the toothed plate one on the outer wall of the male connector, restricting the rotation of the male connector relative to the female connector. At the same time, the slide rod ensures the smooth movement of the toothed plate two, and the stop block prevents the slide rod from disengaging from the mounting bracket. When disassembly is required, the stop block is pulled backward to drive the slide rod to move, so that the toothed plate two compresses the spring and separates from the toothed plate one, and the male connector can be unscrewed. This effectively prevents the threads from loosening due to ultra-high pressure fluid impact, avoids connector failure, and improves connection stability.

[0013] 2. This ultra-high pressure anti-loosening quick connector uses an annular sealing plate inserted into a slot. The tight gap fit restricts fluid leakage and prevents high-pressure fluid from leaking from the joint gap. At the same time, the annular sealing gasket fills the tiny gap through elastic deformation, achieving zero leakage sealing under ultra-high pressure and improving the safety of the connector.

Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0023] Please see Figure 1-4One embodiment of this utility model is: an ultra-high pressure anti-loosening quick connector, including a female connector 1, a male connector 2 threadedly connected to the female connector 1, and an anti-loosening mechanism 3 provided on the female connector 1 and the male connector 2; the anti-loosening mechanism 3 includes: a toothed plate 31 and a mounting bracket 32. The toothed plate 31 is connected to the outer wall of the male connector 2, and the mounting bracket 32 ​​is connected to the outer wall of the female connector 1. The mounting bracket 32 ​​is arranged in an inverted "L" shape. A spring 33 is connected to the inner wall of the back of the mounting bracket 32. A toothed plate 34 is connected to the front end of the spring 33. The toothed plate 31 and the toothed plate 34 are arranged opposite to each other. The toothed plate 34 meshes with the toothed plate 31, forming a mechanical lock through tooth surface engagement, completely restricting the relative rotational freedom of the male connector 2 and the female connector 1, and strengthening the anti-loosening effect. A sliding rod 35 is connected to the back of the toothed plate 34. The outer wall of the sliding rod 35 is slidably connected to the mounting bracket 32. A stop block 36 is connected at the rear end. After the female connector 1 and male connector 2 are connected by threads, the toothed plate 34 is pushed forward by the elastic force of the spring 33, so that it engages with the toothed plate 31 on the outer wall of the male connector 2, restricting the rotation of the male connector 2 relative to the female connector 1. At the same time, the slide rod 35 ensures that the toothed plate 34 moves smoothly, and the stop block 36 prevents the slide rod 35 from disengaging from the mounting bracket 32. When disassembly is required, the stop block 36 is pulled backward to move the slide rod 35, so that the toothed plate 34 compresses the spring 33 and separates from the toothed plate 31, and the male connector 2 can be unscrewed. This effectively prevents the threads from loosening due to the impact of ultra-high pressure fluid, avoids connector failure, and improves connection stability. There are two sets of anti-loosening mechanisms 3. The two sets of anti-loosening mechanisms 3 are set opposite to each other on the outer wall of the female connector 1, and simultaneously realize the engagement of the toothed plate 31 and the toothed plate 34 from both sides, so that the male connector 2 is subjected to balanced force and avoids the off-center load caused by unilateral locking.

[0024] Working principle: After the female connector 1 and male connector 2 are connected by threads, the toothed plate 34 is pushed forward by the elastic force of the spring 33, so that it engages with the toothed plate 31 on the outer wall of the male connector 2, which restricts the rotation of the male connector 2 relative to the female connector 1 and effectively prevents the threads from loosening due to the impact of ultra-high pressure fluid. At the same time, the slide rod 35 ensures that the toothed plate 34 moves smoothly, and the stop block 36 prevents the slide rod 35 from disengaging from the mounting bracket 32. When disassembly is required, pull the stop block 36 backward to drive the slide rod 35 to move, so that the toothed plate 34 compresses the spring 33 and separates from the toothed plate 31, and the male connector 2 can be unscrewed.

[0025] Please see Figure 1-4Based on the above embodiments, in another embodiment of this utility model, a sealing mechanism 4 is provided on the male connector 2. The sealing mechanism 4 includes an annular sealing plate 41, which is connected to the left end of the male connector 2 and inserted into the female connector 1. The annular sealing plate 41 forms a physical barrier to prevent high-pressure fluid from leaking from the joint gap. The sealing mechanism 4 also includes a slot 42, which is opened at the right end of the female connector 1. The annular sealing plate 41 is inserted into the slot 42. The tight gap fit restricts fluid leakage and ensures that the annular sealing plate 41 does not shift under high pressure. An annular sealing gasket 43 is connected to the left end of the annular sealing plate 41, and the outer wall of the annular sealing gasket 43 abuts against the inner wall of the slot 42. The elastic deformation fills the tiny gap, achieving zero leakage sealing under ultra-high pressure and improving the safety of the joint.

[0026] Working principle: The annular sealing plate 41 is inserted into the slot 42. The tight gap fit restricts fluid leakage and prevents high-pressure fluid from leaking from the joint gap. At the same time, the annular sealing gasket 43 fills the tiny gap through elastic deformation, achieving zero leakage sealing under ultra-high pressure and improving the safety of the joint.
