Description

Technical Field

[0001] This utility model relates to the field of hydraulic joint technology, specifically to a snap-fit ​​anti-loosening hydraulic joint. Background Technology

[0002] Hydraulic fittings are an indispensable component in hydraulic systems. Their function is to connect and seal hydraulic pipelines, ensuring the stable transmission of hydraulic media within the system. Currently, the most common connection method for hydraulic fittings on the market is threaded connection. Although threaded connection is widely used, the threads are prone to loosening during long-term use, requiring regular tightening and maintenance. Utility Model Content

[0003] In view of the problems existing in the above-mentioned hydraulic joints, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a snap-fit ​​anti-loosening hydraulic connector, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A snap-fit ​​anti-loosening hydraulic connector includes a female connector end and a male connector end. The female connector end and the male connector end are respectively connected to a first polygonal ring and a second polygonal ring at their closest points. The first polygonal ring is sleeved on the outer wall of the second polygonal ring. Rotating rods are rotatably arranged on both sides of the second polygonal ring. A rotating bar is fixedly connected to the other end of the rotating rod. A locking block is fixedly arranged at the end of the rotating bar away from the rotating rod. Limiting blocks are fixedly arranged on both sides of the first polygonal ring. A T-shaped through groove is opened on the front side wall of the limiting block. The locking block engages with the T-shaped groove. A limiting mechanism is provided on the outer wall of the second polygonal ring to limit the rotation of the two rotating rods.

[0007] Preferably, the limiting mechanism includes a movable ring and two insert rods. The movable ring is slidably sleeved on the upper outer wall of the second polygonal ring. The two insert rods are fixedly disposed on both sides of the lower surface of the movable ring. The rod wall of the rotating rod has an insertion hole, and one end of the insert rod is inserted into the corresponding insertion hole.

[0008] Preferably, cavities are provided inside both the front and rear sides of the first polygonal ring, and a slider is slidably disposed inside the cavity. A connecting rod is fixedly disposed on the lower side of the slider, and the lower end of the connecting rod extends to the outside of the cavity and is fixedly connected to the movable ring.

[0009] Preferably, a spring is fixedly provided on the upper surface of the slider, and the other end of the spring is fixedly connected to the inner wall of the cavity.

[0010] Preferably, a sealing ring is provided on the inner wall of the first polygonal ring.

[0011] Preferably, the inner wall of the T-slot is provided with a rubber pad.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] This invention, by fitting a first polygonal ring onto the outer wall of a second polygonal ring, achieves horizontal positioning of the female and male ends of the connector. Then, rotating the rotating rod causes the rotating bar to engage the locking block in the corresponding T-slot, achieving vertical positioning of the female and male ends. A spring force then pushes the slider downwards, causing the movable ring to move the insertion rod downwards. The insertion rod inserts into the insertion hole on the rotating rod wall, preventing the rotating rod from rotating. This maintains a stable engagement between the locking block and the T-slot, achieving multi-directional positioning of the female and male ends of the connector and effectively preventing loosening of the connection.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] This utility model discloses a snap-fit ​​anti-loosening hydraulic connector.

[0022] Example 1

[0023] Reference Figure 1-3 A snap-fit ​​anti-loosening hydraulic connector includes a female connector end 1 and a male connector end 2. The female connector end 1 and the male connector end 2 are respectively connected to a first polygonal ring 12 and a second polygonal ring 13 at their closest ends. The first polygonal ring 12 is sleeved on the outer wall of the second polygonal ring 13. A sealing ring is provided on the inner wall of the first polygonal ring 12 to improve the sealing between the first polygonal ring 12 and the second polygonal ring 13. Rotating rods 3 are rotatably provided on both sides of the second polygonal ring 13. A rotating bar 4 is fixedly connected to the other end of the rotating rod 3. A locking block 6 is fixedly provided at the end of the rotating bar 4 away from the rotating rod 3. Limiting blocks 5 are fixedly provided on both sides of the first polygonal ring 12. A T-shaped through groove is opened on the front side wall of the limiting block 5. The locking block 6 engages with the T-shaped groove. A rubber pad is provided on the inner wall of the T-shaped groove to make the engagement between the locking block 6 and the T-shaped groove more secure. A limiting mechanism is provided on the outer wall of the second polygonal ring 13 to limit the rotation of the two rotating rods 3.

[0024] Example 2

[0025] Reference Figure 1-3 The limiting mechanism includes a movable ring 7 and two insert rods 11. The movable ring 7 is slidably sleeved on the upper outer wall of the second polygonal ring 13. The two insert rods 11 are fixedly set on both sides of the lower surface of the movable ring 7. The rod wall of the rotating rod 3 has an insertion hole, and one end of the insert rod 11 is inserted into the corresponding insertion hole.

[0026] Example 3

[0027] Reference Figure 1-3 The first polygonal ring 12 has cavities on both the front and rear sides. A slider 9 is slidably installed inside the cavity. A connecting rod 8 is fixedly installed on the lower side of the slider 9. The lower end of the connecting rod 8 extends to the outside of the cavity and is fixedly connected to the movable ring 7. A spring 10 is fixedly installed on the upper surface of the slider 9. The other end of the spring 10 is fixedly connected to the inner wall of the cavity to facilitate the reset of the slider 9.

[0028] In this utility model, during use, the female end 1 and the male end 2 of the connector are brought close together and mated, so that the first polygonal ring 12 is sleeved on the outer wall of the second polygonal ring 13. By utilizing the characteristics of the polygonal structure, the two are relatively limited in the horizontal direction to prevent circumferential rotation.

[0029] Next, rotate the rotating rods 3 on both sides of the second polygonal ring 13. The rotating rods 3 drive the rotating bar 4 to rotate, so that the locking block 6 at the end of the rotating bar 4 is locked into the T-shaped through groove of the limiting block 5. Through the cooperation between the T-shaped through groove and the locking block 6, the relative radial movement of the female end 1 and the male end 2 of the connector is restricted.

[0030] At this time, the spring 10 in the cavity of the first polygonal ring 13 is in its natural state, pushing the slider 9 to move downward. The slider 9 drives the movable ring 7 to slide downward along the outer wall of the second polygonal ring 13 through the connecting rod 8. The two insert rods 11 on the lower surface of the movable ring 7 move downward and are respectively inserted into the insertion holes of the corresponding rotating rod 3, thereby restricting the rotation of the rotating rod 3 and keeping the locking block 6 stably in the T-shaped through groove, realizing multiple limiting of the female end 1 and the male end 2 of the connector, effectively preventing the connection from becoming loose.

[0031] The sealing ring on the inner wall of the first polygonal ring 12 enhances the sealing of the connection, while the rubber gasket on the inner wall of the T-shaped through groove improves the stability of the engagement between the locking block 6 and the T-shaped through groove.

[0032] When it is necessary to separate the connector, pull the movable ring 7 upward. The movable ring 7 drives the slider 9 to move upward through the connecting rod 8 and compress the spring 10, so that the insertion rod 11 disengages from the insertion hole of the rotating rod 3, thereby releasing the rotation restriction on the rotating rod 3. Then rotate the rotating rod 3 in the opposite direction to make the locking block 6 disengage from the T-shaped through groove, so that the female end 1 and the male end 2 of the connector can be separated.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
