As shown in fig. 1, the pipe quick-release structure of the present application includes a first pipe fitting 100, a second pipe fitting 200 and a locking member 300, wherein the first pipe fitting 100 has a first pipe 110 passing therethrough, the second pipe fitting 200 has a second pipe passing therethrough, and one end of the second pipe fitting 200 can be inserted into the first pipe fitting 100 and has a first state in which the first pipe 110 and the second pipe are communicated. In order to maintain the connection state of the first pipe fitting 100 and the second pipe fitting 200, the pipe quick release structure of the present application is provided with a locking member 300. As shown in fig. 2, the first pipe member 100 has a first pipe 110 and a first groove 120, the second pipe member 200 can be inserted into the first pipe 110, the first groove 120 extends along a radial direction of the first pipe 110 and communicates with the first pipe 110, and the locking member 300 is provided to penetrate the first groove 120.
As shown in fig. 2 and 3, the locking member 300 includes a second abutment 330, and the second pipe member 200 is provided with a first abutment 210 extending circumferentially. When the second tube member 200 is in the first state, the lock member 300 has a first position and a second position with respect to the first tube member 100. As shown in fig. 3, which is a cross-sectional view of the locking member 300 in the first position, when the locking member 300 is in the first position, the first abutting portion 210 abuts against the second abutting portion 330 to restrict the displacement of the second pipe member 200 in the extraction direction, and the connected state of the first pipe member 100 and the second pipe member 200 is maintained by the locking member 300. The locking member 300 is movable from a first position to a second position along the radial direction of the first pipe 110, in which the first abutting portion 210 is separated from the second abutting portion 330, so that the second pipe 200 can be extracted with respect to the first pipe 100.
Specifically, the locking member 300 includes a pressing portion 320 for receiving a force and an abutment arm 310 extending from the pressing portion 320, and the second abutment portion 330 is disposed at a free end of the abutment arm 310. When the locking member 300 is located at the first position, the second abutting portion 330 is located in the first pipe 110 along the projection of the axial direction of the first pipe 100, and when the second pipe 200 is inserted, the second abutting portion 330 abuts against the second abutting portion 330, and drives the abutting arm 310 to elastically deform, so that the second pipe 200 can be inserted. When the second pipe member 200 moves to a position communicating with the first pipe member 100, the abutment arm 310 returns to elastic deformation, and the first abutment portion 210 abuts against the second abutment portion 330, and the second abutment portion 330 restricts displacement of the second pipe member 200 in the extraction direction, thereby completing locking of the first pipe member 100 and the second pipe member 200. When the second tube 200 needs to be replaced, pressure is applied to the pressing portion 320 to switch the locking member 300 from the first position to the second position, so that the first abutting portion 210 and the second abutting portion 330 are separated, and the second tube 200 can be pulled out with respect to the first tube 100.
Based on the above, after the second pipe fitting 200 is axially inserted into the first pipe fitting 100, the second pipe fitting 200 can be locked and unlocked by the displacement of the locking member 300 along the radial direction, so that the second pipe fitting 200 can be conveniently disassembled and assembled. Compared with the threaded connection mode, the connection of the first pipe fitting 100 and the second pipe fitting 200 is realized through the switching of the linear positions of the locking piece 300, the first pipe fitting 100 or the second pipe fitting 200 does not need to be repeatedly rotated, the quick disassembly and the quick assembly of the first pipe fitting 100 and the second pipe fitting 200 can be realized, and the disassembly and the assembly of a pipeline in a narrow space are facilitated.
In some embodiments, as shown in fig. 4, the first abutting portion 210 is a first protrusion 211, the first protrusion 211 has an inclined surface 212 and a first limiting surface 213, and the distance from the inclined surface 212 to the outer surface of the second pipe 200 gradually decreases along the insertion direction of the second pipe 200, and the first limiting surface 213 is disposed on the side of the large end of the inclined surface 212, that is, on the side away from the first pipe 100. Since the second abutting portion 330 is located in the first pipe 110, when the second pipe 200 is inserted, the second abutting portion 330 can abut against the inclined surface 212 of the first protrusion 211, and the abutting arm 310 is driven by the inclined surface 212 to be elastically deformed gradually, that is, the distance from the second abutting portion 330 to the central axis of the first pipe 110 is gradually increased. Until the second abutting portion 330 slides over the highest point of the first protrusion 211, the abutting arm 310 returns to the state before elastic deformation, the distance from the second abutting portion 330 to the central axis of the first pipe 110 is reduced to be smaller than the distance from the highest point of the first protrusion 211 to the central axis of the first pipe 110, the first limiting surface 213 is blocked by the second abutting portion 330, the second pipe 200 cannot move in the extraction direction, and the second pipe 200 is maintained in the first state connected with the first pipe 100.
Further, as shown in fig. 4 and 5, the first protrusion 211 further includes a first abutment surface 214, one side of the first abutment surface 214 is connected to the first limiting surface 213, and the other side is connected to the large end of the inclined surface 212, and for convenience of description, a direction in which the locking member 300 moves from the first position to the second position is named as a first direction. The locking member 300 includes a pressing portion 320 and at least one abutting arm 310, and the locking member 300 further includes a third abutting portion 340, where the third abutting portion 340 is disposed on a side of the abutting arm 310 close to the first pipe fitting 100, that is, on the same side of the abutting arm 310 as the first protrusion 211. The third abutting portion 340 and the second abutting portion 330 are disposed in this order along the first direction, that is, the third abutting portion 340 and the second abutting portion 330 are disposed offset from each other, in the projection of the first pipe member 100 onto the abutting arm 310 in the axial direction.
When the locking member 300 moves along the first direction, the third abutting portion 340 can abut against the first abutting surface 214 of the first protrusion 211, and since the first protrusion 211 is disposed around the outer peripheral surface of the second pipe member 200, and the first abutting surface 214 is gradually increased compared with the horizontal plane, for example, the height of the first pipe member 100 and the second pipe member 200 is gradually increased, and the abutting third abutting portion 340 drives the abutting arm 310 to gradually elastically deform outwards, so that the first abutting portion 210 and the second abutting portion 330 are separated, and after the first abutting portion 210 and the second abutting portion 330 are separated, only the abutting relationship between the third abutting portion 340 and the first abutting portion 210 exists between the locking member 300 and the second pipe member 200, and the first limiting surface 213 is not limited in the axial direction, so that the second pipe member 200 can be pulled out in the axial direction.
In some embodiments, as shown in fig. 5, the locking member 300 includes two abutment arms 310, where the two abutment arms 310 are disposed in parallel, and the distance between the free ends of the two abutment arms 310 is gradually increased under the driving action of inserting the second tube 200.

The distance from the second abutting portion 330 to the central axis of the first pipe 110 gradually decreases along the insertion direction of the second pipe 200. Further, when the second pipe member 200 is inserted, the second abutting portion 330 abuts against the end surface of the second pipe member 200, the second pipe member 200 continues to be inserted, the abutting arm 310 is elastically deformed by the drive of the end surface of the second pipe member 200, the distance from the second abutting portion 330 to the central axis of the first pipe 110 gradually increases, when the central axis of the second abutting portion 330 to the first pipe 110 is equal to the outer diameter of the second pipe member 200, the second abutting portion 330 abuts against the outer circumferential surface of the second pipe member 200 and moves in the axial direction of the second pipe member 200, at this stage, the degree of deformation of the abutting arm 310 remains unchanged, and when the second abutting portion 330 moves into the second groove, the abutting arm 310 returns to be elastically deformed, the second abutting portion 330 is engaged with the first abutting portion 210, the displacement of the second pipe member 200 in the extraction direction is restricted by the blocking of the groove wall of the second groove.
Further, the locking member 300 further includes a third abutting portion 340, where the third abutting portion 340 is disposed on a sidewall of any side of the abutting arm 310 along the axial direction of the second pipe fitting 200, and since both sides of the first abutting arm 310 are the second pipe fitting 200, a distance from an outer peripheral surface of the second pipe fitting 200 to the axis is greater than a distance from a bottom of the second groove to the axis. The third abutting portion 340 and the second abutting portion 330 are disposed in this order along the first direction along the projection of the first pipe member 100 on the abutting arm 310, that is, the second abutting portion 330 and the third abutting portion 340 are disposed in a staggered manner, and when the lock 300 is at the first position, the second abutting portion 330 abuts against the first abutting portion 210. When the locking member 300 moves in the first direction, the third contact portion 340 can contact the outer peripheral surface of the second pipe member 200, and further gradually drive the contact arm 310 to elastically deform, so that the second contact portion 330 is disengaged from the second groove.
