[0028] The following will, with reference to the accompanying drawings, elaborate on some embodiments of the present invention. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.
[0029] Embodiment 1
[0030] This embodiment provides a pipeline joint connection structure. Refer to Figures 1 to 5, the pipe joint connection structure 300 is used to connect the female joint 200 and the male joint 100. Specifically, the pipe joint connection structure 300 includes a locking member 1. The locking member 1 includes an annular body 11, and an opening 12 is provided on the circumferential surface of the annular body 11; a claw 14 is also provided on the side surface of the annular body 11. The claw 14 is provided at the edge of the aforementioned opening 12. One end of the claw 14 protrudes toward the outside of the annular body 11, and the other end of the claw 14 bends toward the inside of the annular body 11. In the assembled state, the annular body 11 of the locking member 1 is inserted into the socket of the female joint 200, and the annular body 11 is sleeved outside the male joint 100. One end of the claw 14 inside the annular body 11 abuts against the male joint 100, and one end of the claw 14 outside the annular body 11 abuts against the female joint 200, so as to realize the docking of the pipe joint between the female joint 200 and the male joint 100.
[0031] In the pipe joint connection structure provided in this embodiment, an opening 12 is provided on the circumferential surface of the annular body 11 of the claw 14. The claw 14 is provided at the edge of the aforementioned opening 12. One end of the claw 14 protrudes toward the outside of the annular body 11, and the other end of the claw 14 bends toward the inside of the annular body 11. In the assembled state, one end of the claw 14 inside the annular body 11 abuts against the male joint 100, and one end of the claw 14 outside the annular body 11 abuts against the female joint 200. Thus, when the end of the claw 14 that bends toward the inside of the annular body 11 contacts the male joint 100, there is a tendency to turn outwards, thereby increasing the abutting pressure of the other end of the claw 14 that protrudes outside on the female joint 200, so as to realize a locking function superior to the prior art.
[0032] In this embodiment, it is preferably that the whole locking member 1 or at least the claw 14 is made of an elastic metal or polymer material to avoid breakage of the claw 14 during use.
[0033] Continue to refer to Figures 1 to 5 , in the pipe joint connection structure 300 provided in this embodiment, optionally, an annular protrusion 101 is provided on the outer circumferential surface of the male joint 100. In the assembled state, one end (bent end) of the claw 14 inside the annular body 11 abuts against the annular protrusion 101. Thus, on the basis that one end (bent end) of the claw 14 inside the annular body 11 abuts against the outer circumferential surface of the male joint 100, the bent end of the claw 14 is further limited and supported, so that the claw 14 has a greater tendency to turn outwards, so that the other end (outer protrusion) of the claw 14 presses tightly against the female joint 200, further improving the locking force.
[0034] In this embodiment, optionally but not limited to, a window 201 is provided on the circumferential surface of the female connector 200. In the assembled state, one end of the clamping jaw 14 located outside the annular body 11 abuts against the edge portion of the window 201. Similarly, relative to the end of the clamping jaw 14 located outside the annular body 11 (the outer protrusion) abuts against the inner wall surface of the socket of the female connector 200. This optional structure can further limit and support the outer protrusion end of the clamping jaw 14 through the window 201, so that the outer protrusion end of the clamping jaw 14 presses tightly against the female connector 200, further improving the locking force.
[0035] To further improve the locking force, in this embodiment, optionally but not limited to, a contact protrusion 15 is further provided on the outer surface of the annular body 11. In the assembled state, the contact protrusion 15 abuts against the female connector 200. Further optionally but not limited to, a window 201 is provided on the circumferential surface of the female connector 200. In the assembled state, the contact protrusion 15 abuts against the edge portion of the window 201. Optionally but not limited to, the contact protrusion 15 is wedge-shaped so that its outer peripheral surface forms a guiding surface to better guide the annular body 11 into the socket of the female connector 200.
[0036] In this embodiment, optionally but not limited to, an opening groove 13 extending axially toward the other end of the annular body 11 is provided on the end face where the socket entrance of the annular body 11 is located. The opening groove 13 penetrates the hole wall of its socket along the radial direction of the annular body 11. By providing the opening groove 13, the annular body 11 of the locking member 1 can have better compatibility with male connectors 100 of different sizes. The number of the opening grooves 13 can be one or more, and this embodiment does not limit this.
[0037] In addition, continuing to refer to Figures 1 to 4 , to further increase the connection stability of the joint and, at the same time, increase the sealing performance at the connection between the female connector 200 and the male connector 100, in this embodiment, optionally but not limited to, the pipe joint further includes an isolation ring 3, a first sealing ring 2, and a second sealing ring 4; the socket of the female connector 200 is a stepped hole; in the assembled state, the first sealing ring 2, the isolation ring 3, and the second sealing ring 4 are sequentially sleeved on the outside of the male connector 100 and the opposite end faces of any two of them abut against each other; the end face of the first sealing ring 2 away from the isolation ring 3 abuts against the annular body 11 of the locking member 1, and the end face of the second sealing ring 4 away from the isolation ring 3 abuts against the step surface of the first step 202 in the stepped hole. The isolation ring 3 can isolate the first sealing ring 2 and the second sealing ring 4 so that the two sealing rings do not adhere to each other in the rubber matrix.
[0038] Further optionally, a second step 203 is also provided in the stepped hole. In the assembled state, the end face of the annular body 11 facing one end of the first sealing ring 2 abuts against the step face of the second step 203, so as to further improve the connection tightness of the annular body 11 of the locking member 1, the first sealing ring 2, the isolation ring 3 and the second sealing ring 4 in the axial direction, and further improve the sealing reliability.
