Description

Technical Field

[0001] This utility model relates to the field of pneumatic connector technology, and in particular to a pneumatic connector with an anti-disengagement retaining ring. Background Technology

[0002] Pneumatic couplings are piping fittings used in pneumatic systems to achieve quick and reliable connection or disconnection between components such as air pipes, cylinders, solenoid valves, and air compressors. In applications requiring frequent movement or vibration, such as automated production lines, construction machinery, and mobile equipment, anti-loosening couplings can reduce leakage, pressure drop, and malfunctions caused by loose couplings. Therefore, a pneumatic coupling with an anti-loosening retaining ring is used.

[0003] Pneumatic couplings with anti-detachment retaining rings are based on ordinary quick couplings, with the addition of a special structure of elastic anti-detachment retaining rings. In existing pneumatic coupling technology, after connecting the air hose, there is no additional locking and anti-detachment fixation, which makes it easy for the coupling to fall off during use. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a pneumatic connector with an anti-detachment retaining ring, which aims to improve the problem that the lack of additional locking and anti-detachment fixation after connecting the air tube makes it easy for the connector to fall off during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic connector with an anti-detachment retaining ring, comprising a retaining ring one, a slot and a groove inside the retaining ring one, a pull rod slidably connected inside the retaining ring one, a pull tab fixedly connected to the top end of the pull rod, a connecting piece fixedly connected to the end of the pull rod away from the pull tab, a first spring slidably connected to the outer wall of the pull rod, one end of the first spring fixedly connected to the inside of the retaining ring one, the other end of the first spring fixedly connected to the upper surface of the connecting piece, an insert rod fixedly connected to the lower surface of the connecting piece, the outer walls of the connecting piece and the insert rod slidably connected to the inside of the retaining ring one, a retaining ring two provided on the outer wall of the retaining ring one, an insert block fixedly connected to the outer wall of the retaining ring two, the outer wall of the insert block slidably connected to the inner wall of the slot, the outer wall of the insert rod abutting against the inside of the insert block, and connecting components provided inside both the retaining ring one and the retaining ring two.

[0006] Preferably, the connecting assembly includes a fixed cylinder, the outer wall of which is fixedly connected to the inside of retaining ring one and retaining ring two, and an air tube is slidably connected inside the fixed cylinder.

[0007] Preferably, a sealing ring is fixedly connected to the outer wall of the second retaining ring, and the outer wall of the sealing ring is slidably connected to the inner wall of the retaining groove.

[0008] Preferably, the trachea has multiple fixing grooves inside.

[0009] Preferably, a retaining bead is slidably connected inside the fixing cylinder, the outer wall of the retaining bead is slidably connected to the inner wall of the fixing groove, and a limiting groove is formed inside the fixing cylinder.

[0010] Preferably, a fixing plate is fixedly connected to the outer wall of the ball, and the outer wall of the fixing plate is slidably connected to the inner wall of the fixing cylinder.

[0011] Preferably, a sliding column is fixedly connected to the outer wall of the fixing plate, and the outer wall of the sliding column is slidably connected to the inner wall of the limiting groove.

[0012] Preferably, a second spring is slidably connected to the outer wall of the sliding column, one end of the second spring is fixedly connected to the inside of the fixed cylinder, and the other end of the second spring is fixedly connected to the outer wall of the fixed plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, pulling the pull tab causes the pull rod to slide. Through the cooperation of the connecting piece, the first spring, the insert rod, the insert block and the sealing ring, the first retaining ring and the second retaining ring are aligned. The insert rod is inserted into the insert block to fix the two.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a pneumatic connector with an anti-detachment retaining ring, comprising a retaining ring 1, a slot 2 and a retaining groove 3 inside the retaining ring 1, a pull rod 4 slidably connected inside the retaining ring 1, a pull piece 5 fixedly connected to the top end of the pull rod 4, a connecting piece 6 fixedly connected to the end of the pull rod 4 away from the pull piece 5, a first spring 7 slidably connected to the outer wall of the pull rod 4, one end of the first spring 7 fixedly connected to the inside of the retaining ring 1, the other end of the first spring 7 fixedly connected to the upper surface of the connecting piece 6, an insertion rod 8 fixedly connected to the lower surface of the connecting piece 6, the outer walls of the connecting piece 6 and the insertion rod 8 being slidably connected to the inside of the retaining ring 1, a retaining ring 2 9 provided on the outer wall of the retaining ring 1, an insertion block 10 fixedly connected to the outer wall of the retaining ring 2, the outer wall of the insertion block 10 slidably connected to the inner wall of the slot 2, the outer wall of the insertion rod 8 abutting against the inside of the insertion block 10, and connecting components provided inside both the retaining ring 1 and the retaining ring 2 9.

[0025] Specifically, the retaining ring 1 supports the pull rod 4, and the pull rod 4 fixes the pull piece 5. By pulling the pull piece 5, the pull rod 4 can slide inside the retaining ring 1. The pull rod 4 fixes the connecting piece 6. The first spring 7 is placed between the connecting piece 6 and the retaining ring 1. The first spring 7 will be compressed due to the sliding of the connecting piece 6, and at the same time, the first spring 7 has a rebound function. When the first spring 7 is no longer compressed by the connecting piece 6, it can push the connecting piece 6 to slide in the opposite direction through its own rebound. The connecting piece 6 supports the insertion rod 8. The first retainer 1 and the second retainer 9 serve to fix the plug 10, allowing the plug rod 8 to slide synchronously with the sliding of the connecting piece 6. The second retainer 9 also serves to fix the plug 10. When the first retainer 1 and the second retainer 9 are aligned, the plug 10 will slide into the interior of the first retainer 1. The plug rod 8 serves to limit the position of the plug 10 inside the first retainer 1. By sliding the plug rod 8 into or out of the plug 10, the first retainer 1 and the second retainer 9 can be installed and fixed. Through the docking of the two, the internal air tube 13 can be limited and fixed to prevent it from falling off during use.

[0026] Reference Figure 2 The connecting assembly includes a fixed cylinder 12, the outer wall of which is fixedly connected to the inside of the first retaining ring 1 and the second retaining ring 9, and an air tube 13 is slidably connected inside the fixed cylinder 12; a sealing ring 11 is fixedly connected to the outer wall of the second retaining ring 9, and the outer wall of the sealing ring 11 is slidably connected to the inner wall of the groove 3.

[0027] Specifically, both retaining ring 1 and retaining ring 2 are equipped with a fixing cylinder 12 inside. The fixing cylinder 12 can be spliced ​​by the docking of retaining ring 1 and retaining ring 2. The fixing cylinder 12 supports the air tube 13, and retaining ring 2 fixes the sealing ring 11. By docking retaining ring 2 with retaining ring 1, the sealing ring 11 will slide into the inner wall of the retaining groove 3, thereby sealing retaining ring 2 with retaining ring 1.

[0028] Reference Figure 1 , Figure 4 and Figure 5 The trachea 13 has multiple fixing grooves 14 inside; the fixing cylinder 12 has a slidably connected bead 16 inside, the outer wall of the bead 16 is slidably connected to the inner wall of the fixing groove 14, and the fixing cylinder 12 has a limiting groove 15 inside; the outer wall of the bead 16 is fixedly connected to a fixing piece 17, the outer wall of the fixing piece 17 is slidably connected to the inner wall of the fixing cylinder 12; the outer wall of the fixing piece 17 is fixedly connected to a sliding column 18, the outer wall of the sliding column 18 is slidably connected to the inner wall of the limiting groove 15; the outer wall of the sliding column 18 is slidably connected to a second spring 19, one end of the second spring 19 is fixedly connected to the inside of the fixing cylinder 12, and the other end of the second spring 19 is fixedly connected to the outer wall of the fixing piece 17;

[0029] Specifically, the fixing cylinder 12 supports the retaining bead 16, and the retaining bead 16 restricts the internal position of the air tube 13 and the fixing cylinder 12. The air tube 13 has fixing grooves 14 around its perimeter. When the retaining bead 16 slides into the inner wall of the fixing groove 14, it can limit and fix the position of the air tube 13 and the fixing cylinder 12. The retaining bead 16 also fixes the fixing plate 17. When the retaining bead 16 is squeezed by the air tube 13, it pushes the fixing plate 17 to slide against the inner wall of the fixing cylinder 12. The fixing plate 17 also fixes the sliding column 18, allowing the sliding column 18 to... The sliding column 18 slides along the inner wall of the limiting groove 15, which restricts the sliding trajectory of the sliding column 18 and prevents deviation during sliding. The second spring 19 is placed between the fixing plate 17 and the fixing cylinder 12. The second spring 19 will be squeezed by the sliding of the fixing plate 17, and at the same time, the second spring 19 will rebound. When it is not squeezed, it will push the fixing plate 17 to slide in the opposite direction, thereby pushing the locking bead 16 to lock into the inner wall of the fixing groove 14, which will help limit the position of the fixing cylinder 12 and the air tube 13 and prevent loosening during use.

[0030] Working principle: When this connector is needed, snap ring 1 and snap ring 9 are connected. Pulling the pull tab 5 causes the pull rod 4 to slide inside snap ring 1. When the pull rod 4 slides, it will cause the connecting piece 6 at the bottom to slide at the same time, and during the sliding process, it will squeeze the first spring 7. When the connecting piece 6 slides, it will cause the insertion rod 8 to slide inside snap ring 1, aligning snap ring 1 and snap ring 9. At this time, the insertion block 10 will slide into the inner wall of the slot 2, and the sealing ring 11 will slide into the inner wall of the slot 3. Releasing the pull tab 5, the rebound action of the first spring 7 can push the connecting piece 6 and the insertion rod 8 to slide in the opposite direction, so that snap ring 2 9 can slide into the interior of the insertion block 10, limiting and fixing the insertion block 10 inside snap ring 1. This achieves the effect of fixing and preventing detachment by connecting snap ring 1 and snap ring 2 9 through quick-release design, and can be put into use quickly.

[0031] After retaining ring 1 and retaining ring 9 are fixed, the air tube 13 can be slid into the fixed cylinder 12 for use. When the air tube 13 slides into the fixed cylinder 12, it will contact the retaining bead 16. Continuing to slide inward will compress the retaining bead 16, causing it to slide inside the fixed cylinder 12. When the retaining bead 16 slides, it will push the fixing plate 17 to slide inside the fixed cylinder 12. When the fixing plate 17 slides, it will push the sliding post 18 to slide against the inner wall of the limiting groove 15, and compress the second spring 19 during the sliding process. When the retaining bead 16 slides into the fixing groove 14... After positioning, the second spring 19 is no longer compressed. Through its own rebound, it will push the retaining bead 16 to lock into the inner wall of the fixing groove 14. This achieves the effect of auxiliary positioning of the fixing cylinder 12 and the air tube 13 by the engagement of the four corner retaining beads 16, ensuring stability during use. This connector can not only achieve the effect of fixing and preventing detachment by connecting and fixing retaining ring 1 and retaining ring 2 through quick-release design, but also achieve the effect of auxiliary positioning of the fixing cylinder 12 and the air tube 13 by the engagement of the four corner retaining beads 16, ensuring stability during use.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
