[0022] In order to make the purpose of the invention, the technical scheme and the technical effect of the present invention more clear, the present invention is further described below in conjunction with specific implementation methods. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] Reference Figure 1-5, a quick-install and quick-disassemble pipe joint structure, comprises a joint 10, a plug-in tube 20 and a buckle 30. The plug-in tube 20 is inserted into the joint 10, and the plug-in tube 20 and the joint 10 are quickly fixed and installed or quickly disassembled by the buckle 30. The joint 10 has a pipe body 11 and a connector 12 arranged at the end of the pipe body 11. An accommodating cavity 13 is arranged in the connector 12, and a buckle plug interface 14 connected to the accommodating cavity 13 is arranged on the side wall surface of the connector 12. A pipe plug hole 15 connected to the accommodating cavity 13 is arranged on the upper end surface of the connector 12. The accommodating cavity 13 is connected to the inner cavity of the pipe body 11. The pipe plug hole 15 and the inner cavity of the pipe body 11 are connected to each other and have a common central axis. The buckle 30 passes through the buckle plug interface 14 and is partially accommodated in the accommodating cavity 13, and is partially exposed outside the connector 12. During installation, the buckle 30 is inserted from the buckle insertion interface 14 into the connector 12 and into the accommodating cavity 13, and the plug tube 20 is inserted from the tube plug hole 15 into the accommodating cavity 13 and the buckle 30 is pushed, so that the buckle 30 is simultaneously clamped with the connector 12 and the plug tube 20, thereby realizing a quick fixed connection between the plug tube 20 and the connector 10. During disassembly, the buckle 30 is relatively pressed with external force to release the clamping of the buckle 30 with the connector 12 and the plug tube 20, and the plug tube 20 is pulled out of the connector 12, thereby realizing quick disassembly. The quick-install and quick-disconnect pipe joint 10 structure of the present invention, when installing, the plug-in tube 20 is simultaneously squeezed and clamped by the buckle 30 during the process of inserting the joint 10, so that the buckle 30 simultaneously clamps the connecting head 12 and the plug-in tube 20 to achieve a fixed connection. When disassembling, it is only necessary to press the buckle 30 to release the clamping of the buckle 30 with the connecting head 12 and the plug-in tube 20, and to pull the plug-in tube 20 out of the connecting head 12. The installation and disassembly are fast and the operation is simple.

[0024] In one embodiment of the present invention, referring to Figure 2 and Figure 4 A buckle hole 31 is provided in the middle of the buckle 30. The plug-in tube 20 passes through the buckle hole 31 before being inserted into the inner cavity of the tube body 11. The hole walls on both sides of the buckle hole 31 are respectively provided with a pressing portion 32 and a holding portion 33. The pressing portion 32 is exposed outside the connector 12. The orthographic projection of the holding portion 33 is located inside the tube plug-in hole 15. After the plug-in tube 20 enters the tube plug-in hole 15, the holding portion 33 is pushed so that its orthographic projection is located outside the tube plug-in hole 15, thereby passing through the buckle hole 31 and entering the tube body 11 of the connector 12.

[0025] The pressing portion 32 is provided with first locking protrusions 34 on two opposite sides of the buckle hole 31. The opposite side walls of the connector 12 are provided with locking grooves 16 respectively. 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 interference-fitted and squeezed against each other. When the first locking protrusion 34 moves to the locking groove 16, the first locking protrusion 34 is inserted into the locking groove 16 and locked therewith, thereby fixing the buckle 30 and the connector 12.

[0026] Specifically, the first clamping protrusion 34 includes a connecting arm 341 extending from the pressing portion 32, and the end of the connecting arm 341 extends out of the clamping head 342 toward the inner wall of the connector 12. 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 clamping head 342 are pressed against each other. When the clamping head 342 moves to the clamping slot 16, the clamping head 342 is inserted into the clamping slot 16 and clamped therewith, and the connecting arm 341 and the side wall of the connector 12 are fitted against each other, thereby fixing the buckle 30 and the connector 12.

[0027] Preferably, a clearance position 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 portion 32 is pressed into the accommodating cavity 13 by external force, the clearance position 35 provides a movable space for the first locking protrusion 34 to escape from the locking groove 16, so that the first locking protrusion 34 can smoothly release the clamping state with the connector 12.

[0028] Preferably, two second protrusions 36 are further provided on the wall of the buckle hole 31. A blocking portion 17 cooperating with the second protrusions 36 is provided on the wall of the accommodating cavity 13. The blocking portion 17 blocks the second protrusions 36 to limit the buckle 30 and prevent it from excessively entering the accommodating cavity 13.

[0029] Preferably, the middle edge of the pressing portion 32 is in an arc shape, and the connecting arm 341 is in a straight structure, so as to facilitate the insertion of the buckle 30 into the buckle insertion interface 14.

[0030] Preferably, a limit plate 38 is provided on the upper side or lower side of the pressing portion 32, and a baffle 17 is provided at the buckle insertion interface 14. The baffle 17 blocks the limit plate 38 to limit the position of the buckle 30 inserted into the connecting portion, so that it is partially exposed outside the connecting portion.

[0031] Preferably, the buckle 30 further has two elastic parts 39 protruding from the hole wall on the opposite side of the pressing part 32. The two elastic parts 39 are inclined opposite to each other and elastically resist the cavity wall of the accommodating cavity 13. The pressing part 32 of the buckle hole 31 is pressed into the accommodating cavity 13, so that the first clamping protrusion 34 is separated from the clamping groove 16 and the clamping part 33 is separated from the plug-in tube 20. At this time, the elastic part 39 of the buckle 30 elastically resists the cavity wall of the accommodating cavity 13, the plug-in tube 20 is pulled out, and the pressing part 32 is released. Then, under the action of the rebound force of the elastic part 39, the buckle 30 is reset, and the first clamping protrusion 34 and the clamping groove 16 are mutually clamped. The buckle 30 and the connector 12 resume the clamping connection.

[0032] Reference Figure 2 and Figure 5The plug-in tube 20 includes a main body 21, and a notch groove 22 is provided on the outer wall of the main body 21. When the plug-in tube 20 is inserted into the tube plug-in hole 15 and enters the buckle hole 31 of the buckle 30, the plug-in tube 20 pushes the clamping portion 33 so that its orthographic projection is located outside the tube plug-in hole 15. One side wall of the notch groove 22 is an inclined surface 221 formed by tilting downward from the outer wall of the main body 11. Correspondingly, the hole wall of the buckle hole 31 also forms a corresponding inclined matching surface 311. During the process of inserting the plug-in tube 20 into the tube body 11, the inclined surface 221 and the inclined matching surface 311 match each other, and the guide notch groove 22 and the clamping portion 33 cooperate and clamp each other.

[0033] Preferably, the groove wall on the other side of the notch groove 22 is a convex ring 222 around the tube wall. When the clamping portion 33 enters the notch groove 22, the convex ring 222 and the inclined surface 221 clamp the clamping portion 33 from both sides, so that the plug-in tube 20 is fixedly connected to the buckle 30.

[0034] Preferably, a round spring 18 is further provided inside the tube body 11 and between the tube wall of the plug tube 20 , for elastically pushing the plug tube 20 out of the plug tube 20 after the clamping connection among the plug 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 above-mentioned connector 12 and the above-mentioned buckle 30 , which are respectively connected to a plug-in tube 20 .

[0036] When the quick-install and quick-release pipe joint 10 is installed, the buckle 30 is first inserted into the accommodating cavity 13 of the connector 12 through the buckle insertion interface 14 on the side wall of the connector 12, so that the first clamping protrusion 34 and the clamping groove 16 are mutually clamped, and the orthographic projection of the clamping portion 33 of the buckle hole 31 is located in the pipe plug hole 15. The plug-in pipe 20 is inserted into the accommodating cavity 13 from the pipe plug hole 15, and the clamping portion 33 is squeezed and pushed so that its orthographic projection is located outside the pipe plug hole 15, and the notch groove 22 is clamped with the clamping portion 33, so that the plug-in pipe 20 and the connector 10 are fixedly connected through the buckle 30. When the quick-install and quick-release pipe joint 10 structure is disassembled, the pressing portion 32 of the buckle hole 31 is pressed into the accommodating cavity 13, so that the first locking protrusion 34 is disengaged from the locking groove 16 and the holding portion 33 is disengaged from the notch groove 22 on the plug-in tube 20. The elastic portion 39 of the buckle 30 elastically abuts against the cavity wall of the accommodating cavity 13, the plug-in tube 20 is pulled out, and the pressing portion 32 is released. Under the action of the rebound force of the elastic portion 39, the buckle 30 is reset, and the first locking protrusion 34 and the locking groove 16 are mutually held.
