Description

Technical Field

[0001] This utility model relates to the field of quick coupling technology, and in particular to a high-pressure resistant stainless steel quick coupling structure. Background Technology

[0002] Metal quick couplings are components used to quickly connect or disconnect metal pipelines. They achieve quick connection through snap-fit, threaded, or other structures, and can be operated without tools. They are widely used in hydraulic, pneumatic, and engineering machinery fields. A Chinese utility model patent with publication number CN202914945U, entitled "Quick Connector," includes a male and a female connector. The male connector has a groove, and the female connector has a positioning body that matches the groove and extends into it to position the male and female connectors relative to each other. After the male and female connectors are installed, pulling the inner ring causes the anti-loosening steel ball to leave the U-shaped groove, enhancing the installation force between the male and female connectors. However, under actual high-pressure or high-frequency vibration conditions, the point contact force mode between the anti-loosening steel ball and the U-shaped groove is prone to local wear due to long-term alternating loads, leading to an increase in the mating clearance. When the system pressure rises instantaneously, the axial restraint force between the male and female connectors is insufficient, which may cause accidental separation. This not only affects the normal operation of the equipment but also poses a safety risk due to media leakage. Utility Model Content

[0003] The purpose of this utility model is to provide a high-pressure resistant stainless steel quick connector structure, which uses an L-shaped clamping block in contact with an arc-shaped clamping block surface to improve the stability under high pressure, and works in conjunction with an adjusting disc to achieve synchronous fastening, which can prevent accidental disengagement and effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-pressure resistant stainless steel quick connector structure includes a male connector and a female connector. A fixed plate and a limiting ring are fixedly connected to the outer side of the male connector. Multiple L-shaped clamping blocks are movably connected to one side of the fixed plate. An adjusting plate is rotatably connected to the male connector located between the fixed plate and the limiting ring. Multiple mounting blocks are fixedly connected inside the adjusting plate. A locking block is movably connected inside each mounting block. A first fixed shaft is fixedly connected to one side of each locking block. Pull rings are interlaced between the multiple first fixed shafts. Multiple fixed seats are fixedly connected to the outer side of the female connector. A second fixed shaft is fixedly connected inside each fixed seat. A clamping plate is rotatably connected to the second fixed shaft. Torsion springs are rotatably connected to the second fixed shafts located on both sides of the clamping plate. One side of the torsion spring abuts against the clamping plate. An arc-shaped clamping block is fixedly connected to the side of the clamping plate away from the fixed seat.

[0005] As a further preferred embodiment of this utility model, the male connector has multiple positioning grooves on its outer side, a sealing ring is fixedly connected to the side of the male connector relative to the female connector, the fixed plate has multiple T-shaped sliding grooves on one side, and a through groove is formed on the inner side of the T-shaped sliding grooves. The T-shaped sliding grooves are used to provide installation conditions and a guide path for radial movement of the L-shaped clamping block. The fixed plate has multiple slots along its contour on its outer side. The slots cooperate with the clamping block to limit the circumferential movement of the adjusting plate.

[0006] As a further preferred embodiment of this utility model, a slider is fixedly connected to one side of the L-shaped clamping block, and a third fixed shaft is fixedly connected to one side of the slider. One side of the L-shaped clamping block is slidably connected to the corresponding T-shaped groove through the slider. One side of the third fixed shaft extends through the through groove to the side of the fixed plate opposite to the T-shaped groove. The L-shaped clamping block moves radially within the T-shaped groove through the slider, which can tightly fix the arc-shaped clamping block to one side of the fixed plate, thereby realizing the quick insertion and fastening of the male and female connectors.

[0007] As a further preferred embodiment of this utility model, the adjusting disk has multiple guide grooves on one side, and one side of the third fixed shaft is slidably connected in the corresponding guide groove. After the adjusting disk rotates, it can push the third fixed shaft through the multiple guide grooves, thereby causing the third fixed shaft to drive the slider to slide in the T-shaped groove.

[0008] As a further preferred embodiment of this utility model, a side block is fixedly connected to one side of the mounting block, and a spring groove is provided in the mounting block. A compression spring is fitted on the first fixed shaft located in the spring groove, and one side of the compression spring abuts against one side of the locking block, and the other side abuts against one side of the spring groove. A connecting hole is provided on the side of the first fixed shaft away from the locking block. The locking block can be pushed out of the spring groove and locked into the corresponding locking groove by means of the compression spring in the spring groove. The connecting hole in the first fixed shaft is provided to connect multiple first fixed shafts in series by means of a pull ring.

[0009] As a further preferred embodiment of this utility model, the pull ring is inserted into multiple connecting holes, which can simultaneously pull multiple first fixed shafts, thereby enabling the synchronous movement of multiple locking blocks and achieving rapid limiting after the axial movement of the adjusting disc.

[0010] As a further preferred embodiment of this utility model, the clamping plate is fixedly connected to two shaft blocks on one side relative to the female connector, and a positioning wheel is rotatably connected between the two shaft blocks. The clamping plate can be pre-inserted into the outside of the male connector by the force of the second fixed shaft, so that the positioning wheel is engaged in the corresponding positioning groove, thereby completing the initial positioning of the male connector and the female connector, which facilitates multiple L-shaped clamping blocks to hold the corresponding arc-shaped clamping block.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the L-shaped clamping block and the arc-shaped clamping block are used for surface contact, which improves the stress stability under high pressure conditions and reduces local wear compared with the traditional point contact. At the same time, the torsion spring and the positioning wheel structure ensure precise docking, and the adjustment plate and the guide groove are linked to achieve synchronous fastening of multiple sets of clamping blocks, which enhances the axial constraint force and prevents accidental disengagement when the pressure rises suddenly.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figures 1-6As shown, the present invention provides a high-pressure resistant stainless steel quick connector structure, including a male connector 1 and a female connector 10. A fixed plate 2 and a limiting ring 3 are fixedly connected to the outside of the male connector 1. Multiple L-shaped clamping blocks 4 are movably connected to one side of the fixed plate 2. An adjusting plate 5 is also rotatably connected to the male connector 1 located between the fixed plate 2 and the limiting ring 3. Multiple mounting blocks 6 are fixedly connected inside the adjusting plate 5. A locking block 7 is movably connected inside the mounting block 6. A first fixed shaft 8 is fixedly connected to one side of the locking block 7. Pull rings 9 are interlaced between the multiple first fixed shafts 8. Multiple fixed seats 11 are fixedly connected to the outside of the female connector 10. A second fixed shaft 12 is fixedly connected inside the fixed seat 11. A clamping plate 13 is rotatably connected to the second fixed shaft 12. Torsion springs 14 are also rotatably connected to the second fixed shaft 12 located on both sides of the clamping plate 13. One side of the torsion spring 14 abuts against the clamping plate 13. An arc-shaped clamping block 15 is fixedly connected to the side of the clamping plate 13 away from the fixed seat 11.

[0016] like Figures 1-6As shown, the male connector 1 has multiple positioning grooves 24 on its outer side. A sealing ring 25 is fixedly connected to the side of the male connector 1 relative to the female connector 10. The fixed plate 2 has multiple T-shaped sliding grooves 16 on one side. A through groove 17 is opened on the inner side of the T-shaped sliding groove 16. The T-shaped sliding groove 16 is used to provide installation conditions and a guide path for radial movement of the L-shaped clamping block 4. The fixed plate 2 has multiple slots 18 along its contour on its outer side. The slots 18 cooperate with the clamping block 7 to limit the circumferential movement of the adjusting plate 5. The L-shaped clamping block 4 is fixedly connected to the side of the fixed plate 2. A slider 19 is provided, with a third fixed shaft 20 fixedly connected to one side of the slider 19. An L-shaped clamping block 4 is slidably connected to a corresponding T-shaped groove 16 via the slider 19. The third fixed shaft 20 extends through a through groove 17 to the side of the fixed plate 2 opposite to the T-shaped groove 16. The L-shaped clamping block 4 moves radially within the T-shaped groove 16 via the slider 19, tightly fixing the arc-shaped clamping block 15 to one side of the fixed plate 2, thus achieving quick insertion and fastening of the male connector 1 and the female connector 10. An adjustment disc 5 has an opening on one side... There are multiple guide grooves 28. One side of the third fixed shaft 20 is slidably connected to the corresponding guide groove 28. After the adjusting plate 5 rotates, it can push the third fixed shaft 20 through the multiple guide grooves 28, thereby causing the third fixed shaft 20 to drive the slider 19 to slide in the T-shaped slide groove 16. A side block 21 is fixedly connected to one side of the mounting block 6. A spring groove 22 is opened in the mounting block 6. A compression spring is fitted on the first fixed shaft 8 located in the spring groove 22. One side of the compression spring abuts against one side of the locking block 7, and the other side abuts against the spring groove. On one side of the first fixed shaft 8 away from the locking block 7, a connecting hole 23 is provided. The locking block 7 can be pushed out of the spring groove 22 and locked into the corresponding locking groove 18 by means of the compression spring in the spring groove 22. The connecting hole 23 in the first fixed shaft 8 is provided to connect multiple first fixed shafts 8 in series by pull ring 9. The pull ring 9 is inserted into multiple connecting holes 23. The connecting holes 23 can pull multiple first fixed shafts 8 synchronously, thereby enabling multiple locking blocks 7 to move synchronously and realize rapid limiting after the axial movement of the adjusting plate 5.

[0017] like Figure 2 As shown, the clamping plate 13 is fixedly connected to two shaft blocks 26 on one side of the female connector 10. A positioning wheel 27 is rotatably connected between the two shaft blocks 26. The clamping plate 13 can be pre-inserted into the outside of the male connector 1 by the force of the second fixed shaft 12, so that the positioning wheel 27 is engaged in the corresponding positioning groove 24, thus completing the initial positioning of the male connector 1 and the female connector 10, which makes it easier for multiple L-shaped clamping blocks 4 to clamp the corresponding arc-shaped clamping block 15.

[0018] It should be noted that this utility model is a high-pressure resistant stainless steel quick connector structure. In use, first align the male connector 1 and the female connector 10. The clamping plate 13 on the female connector 10 will open under the action of the torsion spring 14, and the positioning wheel 27 will be inserted into the positioning groove 24 of the male connector 1 to complete the initial connection. Then, rotate the adjusting plate 5. The guide groove 28 of the adjusting plate 5 will push the third fixed shaft 20, allowing the L-shaped clamping block 4 to move in the T-shaped sliding groove 16 of the fixed plate 2 through the slider 19. The L-shaped clamping block 4 slowly approaches and clamps the arc-shaped clamping block 15 of the female connector 10. As the adjusting plate 5 rotates, the clamping becomes tighter and tighter, realizing a firm connection between the male connector 1 and the female connector 10. After the adjusting plate 5 rotates to the appropriate position, the locking block 7 in the mounting block 6 will pop out under the action of the compression spring and lock into the locking groove 18 of the fixed plate 2 to fix the position of the adjusting plate 5 and prevent loosening. During disassembly, pull the pull ring 9. The pull ring 9 drives the first fixed shaft 8 through the connecting hole 23, causing the clamping block 7 to compress the spring and retract into the spring groove 22, disengaging from the clamping groove 18. At this time, rotate the adjusting disc 5 in the opposite direction, and the L-shaped clamping block 4 releases the arc-shaped clamping block 15. Then, forcefully pull the male connector 1 and the female connector 10 in opposite directions respectively. The positioning wheel 27 leaves the positioning groove 24, thus separating the male connector 1 and the female connector 10. The whole process does not require tools and is simple to operate. The L-shaped clamping block 4 and the arc-shaped clamping block 15, which are in surface contact, can withstand high pressure and are suitable for high-pressure and vibration environments.
