[0001] The utility model relates to the technical field of water pipe joints, in particular to a quick-release joint. Background Art

[0002] In real-life production, it's often necessary to connect water pipes, hoses, or pipelines. Hose connectors are commonly used connection tools. Existing water pipe connectors vary in type, primarily featuring a cylindrical body that can connect to water pipes or hoses at either end. For example, Chinese patent publication CN 104455858 A discloses a plastic hose quick connector, comprising a pipe body with locking end caps and locking sleeves symmetrically positioned at both ends. A sealing ring is also positioned on the outer wall of the pipe body, and sealing ring mounting grooves are provided on the outer walls of both ends of the pipe body. This technical solution securely clamps the hose connector through a clamping structure composed of the pipe body, locking end caps, and locking sleeves, achieving a connection. However, this structure cannot achieve the rapid connection or separation of two sections of water pipe. Utility Model Content

[0003] In order to solve the deficiencies in the prior art, a quick-release connector is provided which can realize the rapid connection or disconnection of water pipes.

[0004] The utility model adopts the following technical scheme to be implemented: a quick-release connector, comprising a male connector and a female connector that are plugged in and matched together, the male connector being provided with an axially extending insertion section, and a circle of grooves being provided on the circumferential outer wall of the insertion section; the female connector comprising a shell and a tube body located in the shell, the tube body being plugged in and matched with the insertion section, the tube body comprising a first tube body and a second tube body that are coaxial and spaced apart, a movable snap ring for being sleeved outside the groove is provided between the first tube body and the second tube body; a button connected to the movable snap ring is provided on the shell, and a spring that abuts against the movable snap ring or the button is provided in the shell; the movable snap ring moves radially outward under the action of the spring, so that the movable snap ring and the tube body are eccentrically arranged, so that the part of the movable snap ring facing away from the button is located in the groove to achieve locking of the male and female connectors; when the button is pressed, the movable snap ring moves radially inward, so that the part of the movable snap ring facing away from the button is disengaged from the groove to achieve unlocking of the male and female connectors.

[0005] During use, the user can directly insert the insertion section into the tube body of the female connector and squeeze the movable clasp to move radially inward; or press the button to move the movable clasp radially inward to avoid the insertion section. As the insertion section is inserted, when the groove of the insertion section is covered by the movable clasp, the part of the movable clasp facing away from the button enters the groove, locking the male and female connectors. To unlock, the user presses the button, causing the part of the movable clasp facing away from the button to disengage from the groove. At this time, the insertion section can be pulled out, completing the unlocking of the male and female connectors.

[0006] Among them, under the action of the spring, the movable snap ring is eccentrically arranged with the tube body, so that the part of the movable snap ring away from the button will be stuck in the groove. At the same time, when the button is pressed, the part of the movable snap ring away from the button will be separated from the groove. At this time, the movable snap ring will leave space for the inserted section to be pulled out.

[0007] Among them, the male connector and the female connector respectively have a connection structure for connecting to the pipe body. This structure is an existing connection method. For example, one end of the male connector is provided with an external thread or an internal thread to be connected to the pipe thread.

[0008] Preferably, the first tube body and the second tube body are connected by at least two connecting blocks arranged radially opposite to each other, and the connecting blocks and the first tube body and the second tube body together form a sliding groove that slidably cooperates with the movable clamping ring.

[0009] By arranging the sliding groove to slide with the movable snap ring, the moving path of the movable snap ring is restricted, so that the movable snap ring is more stable when moving.

[0010] Preferably, the circumferential outer wall of the movable snap ring has a first vertical surface, and the connecting block has a second vertical surface that slides in conjunction with the first vertical surface, and both the first vertical surface and the second vertical surface extend in the length direction of the spring.

[0011] The length direction of the spring is also the moving direction of the movable snap ring. The first vertical surface and the second vertical surface both extend toward the length direction of the spring, and the first vertical surface and the second vertical surface are in contact and sliding fit to further guide the movable snap ring.

[0012] Preferably, a limit piece having a width greater than the distance between the first tube body and the second tube body is provided on the side of the movable snap ring away from the button, and the limit piece is used to limit the limit position of the movable snap ring to move radially outward.

[0013] The limiter is used to limit the extreme position of the movable snap ring's movement radially outward, thereby preventing the movable snap ring from moving too radially outward, so that when the insertion section is inserted, the end of the insertion section hits the movable snap ring and cannot enter; wherein, the limiter can be a bolt directly screwed on the movable snap ring, and the width of the bolt head is greater than the distance between the first tube body and the second tube body.

[0014] Preferably, the movable clamping ring limiter is a deformable expansion head, the width of which is reduced when passing through the gap between the first tube body and the second tube body, and returns to its original state after passing through the gap between the first tube body and the second tube body.

[0015] The expansion head is deformed to reduce its width, which makes it easier for users to assemble the movable clamping ring. The expansion head can be integrally injection-molded with the movable clamping ring and can be used for a long time without loosening or fixing problems.

[0016] Preferably, a protrusion is provided on the outer wall of the first tube body or / and the second tube body, and the spring is sleeved on the protrusion.

[0017] The protrusion makes the elastic contraction of the spring more stable.

[0018] Preferably, a sealing ring groove is provided on the circumferential outer wall of the portion of the insertion section that can be plugged into the second tube body, and an O-ring is provided in the sealing ring groove.

[0019] Water leakage is avoided by setting an O-ring, and the second tube body is the movable terminal of the insertion section, so the sealing effect can be improved by setting the O-ring on the circumferential outer wall of the part of the insertion section that can be plugged into the second tube body.

[0020] Preferably, a guide section is provided on the circumferential outer wall of the insertion section at the front end of the groove along the insertion direction, the circumferential outer wall of the guide section is a conical surface, and the diameter of the guide section gradually decreases along the insertion direction.

[0021] The guide section can gradually squeeze the movable snap ring when the insertion section is inserted, so that the movable snap ring moves radially inward until the groove reaches the movable snap ring, so that the part of the movable snap ring away from the button is snapped into the groove.

[0022] Preferably, the movable snap ring has an axial end face and a circumferential inner wall with a rounded transition, and when the insertion section is inserted, the guide section contacts the rounded transition end face and the circumferential inner wall.

[0023] The rounded transition between the end face at one end and the circumferential inner wall makes the guide section smoother during insertion, reduces friction, and increases service life.

[0024] Preferably, the male connector is provided with a first connector for connecting to a water pipe, and the first connector is threadedly engaged with the insertion section; the female connector is provided with a second connector for connecting to a water pipe, and the second connector is coaxially arranged with the pipe body and fixedly connected to the shell.

[0025] The water pipes are connected by the first connecting piece and the second connecting piece, and the joint realizes quick-release docking between the two pairs of water pipes, wherein the first connecting piece and the second connecting piece are any existing components that can connect water pipes.

[0026] Compared with the prior art, the utility model has the advantage of being able to quickly connect or disconnect water pipes. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 3 As shown, this embodiment discloses a quick-release connector, including a male connector 1 and a female connector 2 that are pluggable. One end of the male connector 1 is connected to a first connector 11, which is obliquely connected to the male connector 1 and the two are connected by threaded fitting. A nut is provided at the end of the first connector 11, which is used to connect a water pipe. The male connector 1 is provided with an insertion section 12 extending along its axial direction, and a circle of grooves 13 are provided on the circumferential outer wall of the insertion section 12. The front end of the insertion section 12 (the portion that can be plugged into the second tube body 42) is provided with two sealing ring grooves, and an O-ring 14 is provided in the sealing ring groove.

[0039] like Figures 4 to 9As shown, the female connector 2 includes two housings 8 arranged vertically, and the two housings 8 are fixed by screws (not shown in the figure). Inside the housing 8 of the female connector 2, there is a tube body extending in the axial direction. The tube body includes a first tube body 41 and a second tube body 42 that are coaxial and spaced apart. The first tube body 41 and the second tube body 42 are provided with through holes for inserting the insertion section 12. Inside the housing 8, there is also a second connecting member 21. The second connecting member 21 is coaxial with the first tube body 41 and the second tube body 42 and has a threaded connection head extending outside the housing 8. The threaded connection head is used to connect with a water pipe.

[0040] The first tube body 41 and the second tube body 42 are connected by two connecting blocks 6 arranged radially opposite to each other. The two connecting blocks 6 are located outside the first tube body 41 and the second tube body 42. The cross-sectional shape of the connecting block 6 is in the shape of a "冂", and the connecting block 6 penetrates vertically and forms a vertically penetrating sliding groove between the gaps of the first tube body 41 and the second tube body 42. A movable clamping ring 5 is slidably fitted in the sliding groove. The inner hole diameter of the movable clamping ring 5 is larger than the inner hole diameters of the first tube body 41 and the second tube body 42. The movable clamping ring 5 is fixedly connected to a button 3. The button 3 is arranged on the housing 8. On the outer circumferential wall of the second tube body 42, there is a protrusion 32. A spring 31 is sleeved on the protrusion 32. The spring 31 acts on the button 3 to make the button 3 drive the movable clamping ring 5 to move radially outward. On the outer circumferential wall of the movable clamping ring 5, there is a first vertical surface 51 extending in the up and down direction. The connecting block 6 has a second vertical surface 61 that slidably cooperates with the first vertical surface 51. Both the first vertical surface 51 and the second vertical surface 61 extend in the length direction of the spring 31.

[0041] On one side of the movable clamping ring 5背离按钮3, there is a limiting member with a width greater than the distance between the first tube body 41 and the second tube body 42. The limiting member is an expansion head 52. The expansion head 52 can deform. On the upper end of the opposite side of the first tube body 41 and the second tube body 42, there is a notch 9. The notch 9避让 the expansion head 52; on the radial other side of the notch 9 of the first tube body 41 and the second tube body 42, there is a mating groove 91 cooperating with the expansion head 52. When the expansion head 52 passes through the distance between the mating grooves 91 of the first tube body 41 and the second tube body 42, its width shrinks, and it resumes its original state after passing through the distance between the mating grooves 91 of the first tube body 41 and the second tube body 42.

[0042] As Figure 8 and Figure 9 As shown, on the outer circumferential wall of the insertion section 12 along the insertion direction, at the front end of the groove 13, there is a guiding section 15. The diameter of the guiding section 15 gradually shrinks along the insertion direction (from left to right in the figure) so that the outer circumferential wall of the guiding section 15 is a conical surface. The left end face of the movable clamping ring 5 in the axial direction has a rounded transition with its circumferential inner wall. When the insertion section 12 is inserted, the guiding section 15 contacts the rounded transition end face and the circumferential inner wall.

[0043] When the male connector 1 and the female connector 2 are locked, when the insertion section 12 is inserted into the first tube body 41 and the second tube body 42, the guide section 15 contacts the movable snap ring 5, causing the movable snap ring 5 to move radially inward (downward in the figure). When the groove 13 reaches the position of the movable snap ring 5, since the groove 13 is concave inward, the movable snap ring 5 moves radially outward (upward in the figure) under the action of the spring 31. At this time, the movable snap ring 5 is eccentrically arranged with the first tube body 41 and the second tube body 42, and the portion of the movable snap ring 5 that is away from the button 3 is snapped into the groove 13. This portion is the snap-in portion 7 in the figure. At this time, the entire insertion section 12 is also fully inserted into the first tube body 41 and the second tube body 42 to complete the locking of the male connector 1 and the female connector 2.

[0044] When the male connector 1 and the female connector 2 are unlocked, the user presses the button 3, causing the movable snap ring 5 to move radially inward (downward in the figure), and the snap-in part 7 to disengage from the groove 13. At this time, the insertion section 12 of the male connector 1 can be pulled out to complete the unlocking of the male connector 1 and the female connector 2.
