Description

Technical Field

[0001] This utility model belongs to the field of quick connector technology, specifically relating to high-voltage quick connection connectors. Background Technology

[0002] Quick couplings, also known as fast connectors or quick couplings, are devices that allow for the rapid connection and disconnection of pipelines without the need for tools. They are widely used in industrial fields such as hydraulic, pneumatic systems, and liquid transfer to simplify the installation and maintenance of piping systems.

[0003] Existing quick couplings typically enable quick connections for ordinary pipelines. However, when connecting pipelines with threads, the connection seal is poor. Furthermore, the contact area between the external thread and the coupling is small, resulting in low connection strength and easy detachment. The internal seal of the coupling is usually achieved by pressing it against the end of the threaded pipe, which results in a poor sealing effect. Utility Model Content

It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example

[0020] Please see Figure 1The high-pressure quick-connect connector includes a connector body 1. A threaded connection section 3 is fixedly installed on the left end of the connector body 1. A quick-connect locking mechanism 5 is provided on the right end of the connector body 1. A fixing ring 6 is fixedly connected to the middle of the inside of the connector body 1. A sealing ring 7 is fixedly installed on the right end of the fixing ring 6. A tapered tube 9 is fixedly installed on the inner wall of the fixing ring 6, and a tapered sealing gasket 8 is fixedly sleeved on the outside of the tapered tube 9. Several anti-slip grooves 2 are evenly opened on the middle of the outside of the connector body 1, and a clearance groove 4 is opened on the right end of the connector body 1.

[0021] In use, the quick-connect locking mechanism 5 is used to achieve quick connection and installation. The cooperation of the sealing ring 7 and the conical sealing gasket 8 achieves end-to-end sealing and internal insertion sealing, improving the sealing effect. The anti-slip groove 2 is used for anti-slip.

[0022] Please see Figure 2 and Figure 3 The quick-connect locking mechanism 5 includes a movable sleeve 51, a clamping assembly 52, and a restoring assembly 53. The clamping assembly 52 is disposed outside the fixed ring 6, the movable sleeve 51 is slidably sleeved outside the clamping assembly 52, and the restoring assembly 53 is disposed between the movable sleeve 51 and the connector body 1.

[0023] Please see Figure 2 and Figure 3 The recovery component 53 includes an L-shaped arm 524 uniformly fixedly connected to the outside of the fixed ring 6. The L-shaped arm 524 includes a horizontal section and a vertical section. A pressure wedge block 521 is fixedly connected to the right outer end of the horizontal section of the L-shaped arm 524. A threaded clamping block 522 is fixedly installed on the right inner wall of the L-shaped arm 524. A threaded groove is opened on the inner wall of the threaded clamping block 522. A compression ring 523 that cooperates with the pressure wedge block 521 is fixedly installed on the right inner wall of the movable sleeve 51. A guide rod 55 is fixedly connected to the left outer end of the horizontal section of the L-shaped arm 524. Several limiting grooves 54 are uniformly opened on the left inner wall of the movable sleeve 51. The guide rod 55 is slidably connected inside the limiting grooves 54. The recovery component 53 includes a fixed block 531 uniformly fixedly connected to the inner wall of the movable sleeve 51. A spring 532 is fixedly installed on the left side of the fixed block 531. The left end of the spring 532 is fixedly connected to the right end of the connector body 1.

[0024] In the initial state of use, the horizontal section of the L-shaped arm 524 is compressed towards the center of the movable sleeve 51. When it is necessary to fix the high-pressure quick-connect fitting to the threaded pipe, first pull the movable sleeve 51 towards the threaded connection section 3, and at the same time drive the fixed block 531 to move towards the threaded connection section 3, compressing the spring 532. Then, simultaneously drive the compression ring 523 to move towards the threaded connection section 3. At this time, the compression ring 523 releases the compression of the pressure wedge block 521, and the L-shaped arm 524 returns to the horizontal state. At this time, while keeping the movable sleeve 51 pulled, insert and fix the fitting body 1 onto the threaded pipe until the sealing ring 7 is tightly fitted to the end of the threaded pipe. At the same time, the tapered pipe 9 and the tapered... The sealing gasket 8 is inserted into the threaded pipe. At this time, the conical sealing gasket 8 fits against the inner wall of the threaded pipe, achieving simultaneous internal and external sealing and improving the sealing effect. Then, the movable sleeve 51 is released. Under the restoring force of the spring 532, the fixed block 531 and the movable sleeve 51 on it move away from the connector body 1. At the same time, the compression ring 523 compresses the pressure wedge block 521. After compression, the L-shaped arm 524 and the threaded clamping block 522 move towards the center. At this time, the threaded clamping block 522 clamps and fixes the threaded pipe to the outside, realizing the quick installation and fixation of the quick connector. Moreover, the thread of the threaded clamping block 522 matches the thread of the threaded pipe, with a large contact area, which improves the stability of the fixed installation and effectively prevents slippage.

[0025] It should be noted that when using this high-pressure quick-connect coupling, first pull the movable sleeve 51 towards the threaded connection section 3 to release the compression ring 523 from the pressure wedge block 521. The L-shaped arm 524 returns to a horizontal state. At this time, while keeping the movable sleeve 51 pulled, insert and fix the coupling body 1 onto the threaded pipe until the sealing ring 7 is tightly fitted against the end of the threaded pipe. At the same time, the tapered pipe 9 and the tapered sealing gasket 8 are inserted into the inside of the threaded pipe. At this time, the tapered sealing gasket 8 fits against the inner wall of the threaded pipe, achieving simultaneous tight sealing from the inside and outside, thus improving the sealing effect. After releasing the movable sleeve 51, under the action of the restoring force of the spring 532, the compression ring 523 compresses the pressure wedge block 521. At this time, the threaded clamping block 522 on the L-shaped arm 524 clamps and fixes itself to the outside of the threaded pipe, resulting in a good clamping effect, strong stability, and effective prevention of detachment.

[0026] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
