DETAILED DESCRIPTION

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0028] Based on this, the technical problem that the quick connector in the related art is prone to generate gaps, looseness and reduce the connection sealing performance after long-term use can be improved, and the embodiments of the present application provide the following solutions.

[0029] Please refer to Figures 1 to 5 The embodiments of the present application provide a marine low-pressure large-flow quick connector, which comprises a female connector 10, a male connector 20, a quick connecting assembly 30 and a locking assembly 40, and the female connector 10 is provided with a connecting port 11.

[0030] The quick-connect assembly 30 includes a collar 31 and a plurality of balls 32. The collar 31 is fitted onto the female connector 10. The female connector 10 installs the balls 32 by opening a limiting hole 12. The male connector 20 has a locking opening 21. One side of the balls 32 abuts against the locking opening 21, and the other side abuts against the inner wall of the collar 31.

[0031] The locking assembly 40 includes a limiting ring 41, a connecting ring 42, and multiple bolts 43. The limiting ring 41 is disposed on the female connector 10, and the connecting ring 42 is disposed on the female connector 20. The collar 31 has a limiting port 311 on the side near the connecting port 11. The limiting ring 41 abuts against the inner wall of the limiting port 311. The collar 31 has multiple first threaded holes 312, and the connecting ring 42 has multiple threaded grooves 421. The collar 31 and the connecting ring 42 are fixedly connected by the first threaded holes 312, the threaded grooves 421, and the bolts 43.

[0032] As can be seen from the above, when connecting the connector, move the collar 31 away from the connection port 11 so that the limiting port 311 moves to the limiting hole 12. Move the sub-connector 20 and insert it into the female connector 10 through the connection port 11. Multiple balls 32 abut against the sub-connector 20 and move to the limiting port 311 under the resistance of the sub-connector 20. Continue to move the sub-connector 20 until the connecting ring 42 abuts against the female connector 10. At this time, the locking port 21 corresponds to the limiting hole 12. Move the collar 31 closer to the connection port 11. Multiple balls 32 and the inner wall of the collar 31... The balls roll and lock the sub-body tightly under the resistance of the collar 31. The first threaded hole 312 is aligned with the threaded groove 421, and the bolt 43 is rotated through the first threaded hole 312 and rotated into the threaded groove 421, so that the collar 31 is fixedly connected to the connecting ring 42. At this time, the limiting ring 41 abuts against the inner wall of the limiting port 311, forming a secondary fixed connection. This makes it difficult for the quick coupling to develop gaps and loosen after long-term use in marine low-pressure and high-flow environments. The connection is stable and leaks are unlikely to occur.

[0033] Optionally, in some embodiments, please refer to Figures 1 to 5 The four bolts 43 are arranged in a ring array around the collar 31.

[0034] This arrangement, with the four bolts 43 positioned so that they can securely connect and fix the collar 31 to the connecting ring 42 around the perimeter, enhances the fixing effect of the bolts 43, and reduces the probability of the quick coupling loosening during use.

[0035] Optionally, in some embodiments, please refer to Figures 3 to 5A plurality of sliding blocks 313 are arranged on the inner wall of the sleeve ring 31, and a plurality of sliding grooves 13 are arranged on the outer wall of the female joint 10, and the sliding blocks 313 are slidingly arranged in the sliding grooves 13.

[0036] In this way, the sliding blocks 313 are slidingly arranged in the sliding grooves 13, so that the sleeve ring 31 is not prone to shaking during movement and is difficult to rotate during use, thereby reducing the frequency of friction between the sleeve ring 31 and the balls 32 and the limiting ring 41 and prolonging the service life of the sleeve ring 31, the balls 32 and the limiting ring 41.

[0037] Optionally, in some embodiments, referring to Figures 4 to 5 A plurality of limiting strips 22 are arranged on the sub-joint 20, and a plurality of limiting grooves 111 are arranged on the inner wall of the connecting port 11 for the limiting strips 22 to pass through.

[0038] In this way, when the sub-joint 20 is connected to the female joint 10, the sleeve ring 31 is moved away from the connecting port 11 so that the limiting port 311 is moved to the limiting hole 12, the limiting strips 22 are aligned with the limiting grooves 111, the sub-joint 20 is moved to pass through the connecting port 11 and be inserted into the female joint 10, the limiting strips 22 are slidingly arranged in the limiting grooves 111, the plurality of balls 32 abut against the sub-joint 20, and the connecting ring 42 abuts against the female joint 10. At this time, the locking port 21 corresponds to the limiting hole 12, the sleeve ring 31 is moved towards the connecting port 11, the plurality of balls 32 abut against the inner wall of the sleeve ring 31 and are moved to the locking port 21 under the resistance of the sleeve ring 31, and the steel balls are rolled to lock the sub-body tightly. At this time, the first threaded hole 312 corresponds to the threaded groove 421, and the bolt 43 is rotated to pass through the first threaded hole 312 and is rotated to be connected in the threaded groove 421, so that the sleeve ring 31 is fixedly connected to the connecting ring 42. At this time, the limiting ring 41 abuts against the inner wall of the limiting port 311 to form a secondary fixed connection. Therefore, the limiting strips 22 and the limiting grooves 111 are arranged in cooperation with the sliding blocks 313 and the sliding grooves 13, so that the threaded holes and the threaded grooves 421 are located on the same horizontal line during the butt joint of the sub-joint 20 and the female joint 10, which facilitates the user to correspond the first threaded hole 312 to the threaded groove 421 and connect them through the bolt 43.

[0039] Optionally, in some embodiments, referring to Figures 2 to 3 A sealing ring 113 is arranged on the inner wall of the connecting port 11 by arranging an annular groove 112.

[0040] In this way, after the sub-joint 20 and the female joint 10 are connected, the inner side of the sealing ring 113 abuts against the outer wall of the sub-joint 20, and the outer side abuts in the annular groove 112 to form a seal.

[0041] Optionally, in some embodiments, referring to Figures 3 to 5The diameter of the opening of the limiting hole 12 near the side of the connecting port 11 is smaller than the diameter of the ball 32.

[0042] In this way, the diameter of the opening of the limiting hole 12 near the side of the connecting port 11 is smaller than the diameter of the ball 32, so as to prevent the ball 32 from falling out of the limiting hole 12 during use of the sub connector 20.

[0043] Optionally, in some embodiments, referring to Figures 1 to 5 The female connector 10 and the sub connector 20 are respectively provided with a second threaded hole 14 and a third threaded hole 23 at the ends away from each other.

[0044] In this way, the second threaded hole 14 and the third threaded hole 23 are used to facilitate the connection of the female connector 10 and the sub connector 20 to the corresponding pipelines.

[0045] Optionally, in some embodiments, referring to Figures 1 to 2 The outer wall of the sleeve ring 31 is provided with a plurality of anti-skid strips 314.

[0046] In this way, the anti-skid strips 314 are used to facilitate the movement of the sleeve ring 31 by the user.

[0047] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
