[0041] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, elaborate in detail on the specific implementation manner, structure, features and effects of the quick-lock joint assembly proposed according to the present invention as follows.

[0042] Please refer to Figures 1-5 , which is a schematic diagram of the structures of various parts of the quick-lock joint assembly of the present invention. The quick-lock joint assembly includes a plug assembly and a socket assembly that are inserted into each other. The plug assembly includes a housing of the plug integrated device, and a self-locking rod and at least two plugs are provided inside the housing of the plug integrated device. The socket assembly includes a housing of the socket integrated device, at least two sockets, a handle assembly and a handle locking mechanism. The handle assembly includes a handle and a curved groove housing that is fixedly connected to one end of the handle and is rotatably assembled inside the housing of the socket integrated device and is used for inserting and corresponding to the self-locking rod of the plug assembly. The cooperation and limitation of the curved groove on the curved groove housing of the present invention and the stud on the outer peripheral surface of the self-locking rod, by rotating the handle, make the self-locking rod drive the plug assembly to move towards the socket assembly to achieve the insertion of the joint assembly. When the socket assembly and the plug assembly of the joint assembly are inserted in place, the handle locking mechanism locks the handle on the housing of the socket integrated device to prevent it from rotating. In another embodiment of the present invention, the self-locking rod is provided on the housing of the socket integrated device, and the handle assembly and the handle locking mechanism are provided on the housing of the plug integrated device.

[0043] In the embodiment of the present invention, the plug assembly includes a housing 5 of the plug integrated device. The self-locking rod 10 is located in the middle of the housing 5 of the plug integrated device, and two plugs are symmetrically distributed on both sides of the self-locking rod 10. The curved groove housing of the handle assembly in the socket assembly is rotatably provided in the middle of the housing 21 of the socket integrated device, and two sockets are symmetrically distributed on both sides of the curved groove housing. And the curved groove housing is a two-curved groove housing 33. A stud is provided on the self-locking rod 10 for limiting and cooperating with the curved groove on the two-curved groove housing 33. Through the limiting cooperation of the stud and the two-curved groove, when the handle rotates, the self-locking rod drives the plug assembly to move towards the socket assembly to make it inserted.

[0044] The hand-locking mechanism includes a locking button mechanism located on the handle 38 and a locking mechanism located on the socket integration device housing. The locking mechanism is located in the through groove 39 of the socket integration device housing below the handle 38 when the joint assembly is inserted in place. The locking mechanism includes a built-in locking rod 15 located in the through groove 39, and a convex portion is provided at the lower part of the built-in locking rod 15 to stop and limit the lower end face of the annular protrusion in the through groove 39. The upper end of the built-in spring 14 sleeved on the built-in locking rod 15 presses on the annular convex platform at the upper part of the built-in locking rod, and the lower end presses on the upper end face of the annular protrusion in the through groove 39, and the upper end face of the built-in locking rod 15 extends out of the through groove 39. In the embodiment of the present invention, a built-in gasket 13 and a built-in O-ring 12 are further provided between the upper end of the built-in spring 14 and the lower end face of the convex platform at the upper part of the built-in locking rod. The built-in O-ring 12 is embedded on the outer peripheral surface of the built-in locking rod 15 to achieve the sealing between the built-in locking rod and the through groove 39, and the built-in spring 14 presses the built-in gasket 13 tightly on the built-in O-ring 12. The arrangement of the built-in gasket and the built-in O-ring makes the axial movement of the built-in locking rod in the through groove more stable, and the relationship between the built-in spring and the built-in locking rod more reliable.

[0045] In the embodiment of the present invention, the convex portion of the lower part of the built-in locking rod 15 that stops and limits the lower end face of the annular protrusion in the through groove 39 is a built-in locking screw threadedly connected to the end of the built-in locking rod 15. The built-in locking screw enters the through groove from the lower opening of the through groove 39, but it is not limited thereto.

[0046] The locking button mechanism includes a lock handle rod 37 inserted through the variable-diameter through hole 40 on the handle. The top of the lock handle rod 37 extends above the handle and is connected to the button 36. The bottom of the lock handle rod 38 has a stop convex edge. The handle return elastic body presses between the convex edge and the step surface in the through hole and provides a force for the lock handle rod 38 in the direction away from the button 36, so that the lower end face of the button 36 stops at the upper end face of the through hole 40, and the distance between the bottom end face of the lock handle rod 38 and the lower end face of the through hole 40 is less than the height of the upper end face of the built-in locking rod 15 protruding above the through groove 39. In the embodiment of the present invention, the handle return elastic body is a handle spring 34.

[0047] On the side of the handle 38 facing the built-in locking rod, a guiding bevel is further provided for guiding the built-in locking rod into the through hole 40. When the handle rotates to a position close to the built-in locking rod and continues to rotate the handle, the guiding bevel on the handle presses on the upper end face of the above-mentioned built-in locking rod and continuously presses down the built-in locking rod as the handle rotates. When the handle rotates in place, the built-in locking rod enters the through hole 40 and pushes the lock handle rod 38 upward, causing the button 36 to protrude. In the embodiment of the present invention, a guiding groove is further provided between the guiding bevel and the through hole 40, and the built-in locking rod enters the through hole 40 through the guiding groove from the guiding bevel, but it is not limited thereto.

[0048] In the embodiment of the present invention, both the plug and the socket are self-sealing structures. The plug includes a plug disc housing 8, which is assembled in a plug mounting hole on the plug integrated device housing, and axially front-end stop and limit are achieved through the interference fit between the outer convex edge provided on the front outer peripheral surface thereof and the stop at the front end of the mounting hole. Axial rear-end stop and limit are achieved through the interference fit between the elastic retaining ring embedded on the rear outer peripheral surface and the stop at the rear end of the mounting hole. A support rod is also embedded outside the plug mounting hole, which is located below the front outer convex edge of the plug disc housing 8, supports below the outer convex edge, and stops in the radial direction of the plug disc housing 8. An O-ring II 3 for achieving sealing between the plug housing and the plug integrated device housing is also embedded in the plug mounting hole.

[0049] Inside the plug disc housing 8, a sealing block 1, a plug spring 4, and a support block 6 with axial rearward limit are sequentially arranged from front to back. The plug spring 4 is in a pre-compressed state. The sealing block 1 is blocked at the front end sealing of the plug housing through the guide rod at the lower part of the sealing block 1, and forms a sealing structure with the O-ring I 2 at the sealing part, so that the plug assembly is in a self-sealing state. At this time, the axial forward limit of the sealing block is achieved through the interference fit between the protrusion on its outer end surface and the inner wall of the plug housing.

[0050] The socket disc housing 30 is assembled in a socket mounting hole on the socket integrated device housing, and has axial limits in both the forward and backward directions. The forward axial limit is achieved through the snap ring II 18 embedded on the rear outer peripheral surface thereof, and the backward axial limit is achieved through the cooperation between the protrusion on its outer peripheral surface and the groove on the mounting hole. Inside the socket disc housing 30, there is a support ring 19 whose front end surface stops on the step surface inside the socket disc housing 30 and whose rear end surface stops on the snap ring I 20 embedded in the socket disc housing 30. The rear end of the sealing rod 29 is fixed on the support ring 19, and the front end sequentially passes through the sealing ring 23 and the sleeve 26. One end of the socket spring II 22 sleeved on the sealing rod 29 presses on the support ring 19, and the other end presses on the sealing ring 23, so that the sealing ring 23 and the socket O-ring II 27 cooperate to achieve sealing with the socket disc housing 30. The front end of the sleeve 26 presses on the seal on the front end of the sealing rod 29, the rear end of the socket spring I presses on the protrusion inside the sealing ring 23, and the front end presses on the protrusion outside the sleeve 26. Sealing between the seal on the front end of the sealing rod 29 and the sealing ring 23 is achieved through the socket O-ring I 28.

[0051] In the disconnected state of the quick-lock joint assembly of the present invention, the spring in the plug assembly is in a pre-compressed state, and the spring force acts on the sealing block through the guide rod, so that the sealing block and the O-ring 1 form a sealing structure, and the plug assembly is in a self-sealing state. The socket spring 2 in the socket assembly is in a pre-compressed state, and the spring force acts on the sealing ring, so that the sealing ring forms sealing structures with the socket O-ring 1 and the socket O-ring 2 at the same time, and the socket assembly is in a self-sealing state.

[0052] The insertion process of the present invention includes five stages, namely: the preparation for insertion stage, the start of insertion stage, the intermediate insertion stage, the full insertion stage, and the separation stage.

[0053] In the preparation for insertion stage, under the guiding action of the sub-component self-locking rod, the plug component slowly enters the socket component linearly. At this time, the staple has not yet entered the socket component.

[0054] In the start of insertion stage, the self-sealing joints of the plug component and the socket component start to contact. The staple is at the starting rotation position of the two-curved groove mechanism. After the plug component moves linearly in place, the handle can be rotated.

[0055] In the intermediate insertion stage, rotate the handle to drive the two-curved groove mechanism to rotate. The two-curved groove mechanism drives the self-locking rod to move linearly, and the self-locking rod drives the entire plug component to move linearly, thereby inserting it into the socket component, and the channel of the self-sealing joint gradually opens.

[0056] In the full insertion stage, after the handle rotates in place, under the automatic action of the locking mechanism, the button protrudes, and the handle component is in a self-locking state, and the channel of the self-sealing joint opens.

[0057] In the separation stage, the process of disconnecting the quick connector is the reverse of the insertion process, that is, initially press the button of the lock handle mechanism, rotate the handle, start to disconnect, and finally separate. In this separation process, mainly rely on the rotational movement of the two-curved groove mechanism to make the plug and socket components separate smoothly.

[0058] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in this field, without departing from the technical solution scope of the present invention, can make some changes or modifications to equivalent embodiments with equivalent changes by using the above-disclosed technical content. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
