[0022] To make the utility model's objectives, technical solutions, and effects clearer, the present invention will be further described below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0023] Reference Figure 1-5The quick-install and quick-release pipe fitting structure includes a fitting 10, a connector 20, and a snap fastener 30. The connector 20 is inserted into the fitting 10, and the snap fastener 30 allows for quick installation or disassembly of the connector 20 and fitting 10. The fitting 10 has a pipe body 11 and a connector 12 located at the end of the pipe body 11. The connector 12 has a receiving cavity 13, and a snap-fit ​​interface 14 communicating with the receiving cavity 13 is provided on the side wall of the connector 12. The upper end face of the connector 12 has a pipe insertion hole 15 communicating with the receiving cavity 13. The receiving cavity 13 communicates with the inner cavity of the pipe body 11. The pipe insertion hole 15 and the inner cavity of the pipe body 11 are interconnected and share a common central axis. The snap fastener 30 passes through the snap-fit ​​interface 14 and is partially received within the receiving cavity 13, while partially protruding outside the connector 12. During installation, the clip 30 is inserted into the connector 12 through the snap-fit ​​interface 14 and into the receiving cavity 13. The insertion tube 20 is inserted into the receiving cavity 13 through the tube insertion hole 15 and pushes the clip 30, so that the clip 30 simultaneously engages with the connector 12 and the insertion tube 20, thereby achieving a quick and secure connection between the insertion tube 20 and the connector 10. During disassembly, external force is applied to press the clip 30 relative to each other to release the engagement between the clip 30 and the connector 12 and the insertion tube 20, and the insertion tube 20 is pulled out from the connector 12, achieving quick disassembly. The quick-install and quick-disconnect pipe connector 10 structure of this utility model allows for installation by simultaneously squeezing and locking the buckle 30 during the insertion of the insertion pipe 20 into the connector 10. This allows the buckle 30 to simultaneously lock the connector 12 and the insertion pipe 20 for a fixed connection. During disassembly, simply pressing the buckle 30 releases the buckle 30 from the connector 12 and the insertion pipe 20, allowing the insertion pipe 20 to be pulled out of the connector 12. Installation and disassembly are quick and easy to operate.

[0024] In one embodiment of this utility model, reference is made to Figure 2 and Figure 4 The buckle 30 has a buckle hole 31 in the middle. The insertion tube 20 passes through the buckle hole 31 before being inserted into the inner cavity of the tube body 11. The two opposite sides of the buckle hole 31 are respectively provided with a pressing part 32 and a holding part 33. The pressing part 32 is exposed outside the connector 12. The orthographic projection of the holding part 33 is located inside the tube insertion hole 15. After the insertion tube 20 enters the tube insertion hole 15, it pushes the holding part 33 so that its orthographic projection is outside the tube insertion hole 15, thereby passing through the buckle hole 31 and entering the tube body 11 of the connector 12.

[0025] The pressing part 32 has a first locking protrusion 34 on both sides opposite to the buckle hole 31. The connector 12 has a locking groove 16 on each of its opposite side walls. When the buckle 30 is inserted into the connector 12 from the buckle insertion interface 14, the side wall of the connector 12 and the first locking protrusion 34 are press-fitted together and squeeze each other. When the first locking protrusion 34 moves to the locking groove 16, the first locking protrusion 34 inserts into the locking groove 16 and holds it, thereby fixing the buckle 30 and the connector 12 together.

[0026] Specifically, the first latching protrusion 34 includes a connecting arm 341 extending from the pressing part 32, and a retaining head 342 extending from the end of the connecting arm 341 toward the inner wall of the connector 12. When the latch 30 is inserted into the connector 12 from the latching interface 14, the side wall of the connector 12 and the retaining head 342 are pressed against each other. When the retaining head 342 moves to the slot 16, the retaining head 342 is inserted into the slot 16 and holds it in place. The connecting arm 341 and the side wall of the connector 12 fit together, thereby fixing the latch 30 to the connector 12.

[0027] Preferably, a clearance 35 is provided between the first locking protrusion 34 and the annular wall of the buckle hole 31 and the locking groove 16. When the pressing part 32 is pressed into the receiving cavity 13 by external force, the clearance 35 provides room for the first locking protrusion 34 to disengage from the locking groove 16, so that the first locking protrusion 34 can be smoothly released from the locking state with the connector 12.

[0028] Preferably, the wall of the buckle hole 31 is further provided with two second latching protrusions 36. The wall of the receiving cavity 13 is provided with a blocking part 17 that cooperates with the second latching protrusions 36. The blocking part 17 blocks the second latching protrusions 36, thereby limiting the buckle 30 and preventing it from excessively entering the receiving cavity 13.

[0029] Preferably, the middle edge of the pressing part 32 is arc-shaped, and the connecting arm 341 has a straight structure, so as to facilitate the insertion of the buckle 30 into the buckle interface 14.

[0030] Preferably, a limiting plate 38 is provided on the upper or lower side of the pressing part 32, and a baffle 17 is provided at the snap-fit ​​interface 14. The baffle 17 blocks the limiting plate 38, thereby restricting the position of the snap fastener 30 inserted into the connecting part, so that part of it is exposed outside the connecting part.

[0031] Preferably, the latch 30 further protrudes two elastic portions 39 on the hole wall opposite to the pressing portion 32. The two elastic portions 39 are inclined opposite each other, elastically abutting against the cavity wall of the receiving cavity 13. Pressing the pressing portion 32 of the latch hole 31 into the receiving cavity 13 causes the first latching protrusion 34 to disengage from the slot 16 and the holding portion 33 to disengage from the insertion tube 20. At this time, the elastic portions 39 of the latch 30 elastically abut against the cavity wall of the receiving cavity 13, pulling out the insertion tube 20 and releasing the pressing portion 32. Then, under the rebound force of the elastic portions 39, the latch 30 resets, and the first latching protrusion 34 and the slot 16 are mutually locked. The latch 30 and the connector 12 return to the locked connection.

[0032] Reference Figure 2 and Figure 5The insertion tube 20 includes a main body 21, and the outer wall of the main body 21 has a notch 22. When the insertion tube 20 is inserted into the tube insertion hole 15 and enters the buckle hole 31 of the buckle 30, the insertion tube 20 pushes the retaining part 33 so that its orthographic projection is outside the tube insertion hole 15. One side wall of the notch 22 is an inclined surface 221 formed downward from the outer wall of the main body 11. Correspondingly, the hole wall of the buckle hole 31 also forms a corresponding inclined mating surface 311. During the process of the insertion tube 20 being inserted into the tube body 11, the inclined surface 221 and the inclined mating surface 311 match each other, and the guide notch 22 and the retaining part 33 cooperate to retain each other.

[0033] Preferably, the groove wall on the other side of the notch 22 is a convex ring 222 that wraps around the pipe wall. When the retaining part 33 enters the notch 22, the convex ring 222 and the inclined surface 221 clamp the retaining part 33 from the upper and lower sides, thereby fixing the insertion pipe 20 to the buckle 30.

[0034] Preferably, a circular spring 18 is provided inside the tube body 11 and between the tube wall of the insertion tube 20, for elastically pushing the insertion tube 20 out of the insertion tube 20 after the locking connection between the insertion tube 20, the connector 12 and the buckle 30 is released.

[0035] Preferably, the two ends of the tube body 11 of the connector 10 are respectively provided with the aforementioned connector 12 and the aforementioned buckle 30, and are respectively connected to a plug tube 20.

[0036] During installation, the quick-connect and quick-release pipe connector 10 is first inserted into the receiving cavity 13 of the connector 12 through the snap-fit ​​interface 14 on the side wall of the connector 12, so that the first snap protrusion 34 and the snap groove 16 are mutually engaged, and the orthographic projection of the holding part 33 of the snap hole 31 is located inside the pipe insertion hole 15. The insertion pipe 20 is inserted into the receiving cavity 13 from the pipe insertion hole 15, and the snap-fit ​​part 33 is pushed so that its orthographic projection is located outside the pipe insertion hole 15, and the notch 22 is engaged with the snap-fit ​​part 33, thereby fixing the insertion pipe 20 and the connector 10 together through the snap 30. When the quick-release pipe connector 10 is disassembled, the pressing part 32 of the buckle hole 31 is pressed into the receiving cavity 13, so that the first locking protrusion 34 disengages from the slot 16 and the holding part 33 disengages from the notch 22 on the insertion tube 20. The elastic part 39 of the buckle 30 elastically abuts against the cavity wall of the receiving cavity 13. The insertion tube 20 is pulled out and the pressing part 32 is released. Under the rebound force of the elastic part 39, the buckle 30 is reset and the first locking protrusion 34 and the slot 16 are mutually locked.

[0037] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
