[0025] See attached Figure 1 The embodiment of the present application provides a quick-connect pipe joint, including a first joint 100 and a second joint 101, which are respectively integrally formed with the pipes to be connected on both sides. The first joint 100 is provided with an inner end face, and the second joint 101 is provided with a convex shoulder. The second joint 101 is inserted into the first joint 100 by the convex shoulder and fits with the inner end face. At the same time, the first joint 100 and the second joint 101 are mutually locked and fixed by an elastic locking member.

[0026] See also Figure 2As shown, multiple elastic locking members are arranged along the circumference of the first joint 100, and the elastic locking members include a latch pin 102 and a spring pin 103. In the connection section between the first joint 100 and the second joint 101, a plug hole is opened from the outside of the first joint 100 to the second joint 101, and the plug hole is perpendicular to the axial direction of the first joint 100 and the second joint 101. The latch pin 102 is inserted into the plug hole, and a first wedge surface 104 is formed at the bottom of the latch pin 102. A countersunk hole is arranged inside the side wall of the second joint 101 along its axial direction, and the countersunk hole is perpendicular to and communicates with the plug hole. The spring pin 103 is installed in the countersunk hole, and an upward second wedge surface 105 is arranged on the end face of the spring pin 103 located on one side of the countersunk hole, and the first wedge surface 104 and the second wedge surface 105 are matched. In a natural state, the spring pin 103 extends out of the countersunk hole and vertically enters the plug hole. When the spring pin 103 is pressed, it can be completely pressed into the countersunk hole. After the plug pin 102 is inserted into the insertion hole, a position corresponding to the spring pin 103 is arranged in the pin hole, so that after the plug pin 102 is inserted into the pin hole, the spring pin 103 can be inserted into the pin hole.

[0027] It can be imagined that after the second connector 101 is inserted into the first connector 100, the latch 102 is inserted into the socket. Since the latch 102 and the spring pin 103 are provided with matching first wedge surfaces 104 and second wedge surfaces 105, the spring pin 103 is pressed into the countersunk hole during the downward insertion of the latch 102. After the latch 102 is fully inserted into the socket, the pin hole is opposite to the spring pin 103, and the spring pin 103 bounces into the pin hole, so that the spring pin 103 cooperates with the latch 102 to lock the first connector 100 and the second connector 101.

[0028] In an exemplary embodiment, in order to securely lock the latch pin 102 on the first connector 100 after locking, Figure 2 As shown, the elastic locking member also includes a pressing plate 106 disposed outside the latch 102, and the pressing plate 106 and the first connector 100 are buckled with each other through a connecting member. During installation, after the latch 102 is pressed into the insertion hole and locked with the spring pin 103 by the pressing plate 106, the pressing plate 106 is buckled with the first connector 100 through the connecting member, thereby preventing the latch 102 from being separated from the first connector 100.

[0029] The above Figure 2 As shown, the connecting piece includes a fishbone buckle 107 arranged on the inner side of the pressing plate 106. The fishbone buckle 107 can gather toward the middle after being pressed. The outer wall of the first joint 100 is provided with a fishbone buckle groove matching with the fishbone buckle 107. When pressure is applied to the pressing plate 106, the fishbone buckle 107 gathers toward the middle. After corresponding to the fishbone buckle groove, the fishbone buckle 107 resets and opens, thereby forming a snap connection with the fishbone buckle groove, and fixing the pin 102 and the pressing plate 106 on the first joint 100.

[0030] In this embodiment, in order to make the jacks on the first connector 100 and the second connector 101 correspond to each other after the first connector 100 and the second connector 101 are plugged in, see Figure 2 As shown, a guide strip 109 is provided on the inner end surface facing the second joint 101, and a guide hole is provided at the end of the second joint 101. The guide strip 109 is inserted into the guide hole, thereby guiding the docking of the first joint 100 and the second joint 101, so that after the first joint 100 and the second joint 101 are docked, the sockets on the first joint 100 and the second joint 101 can accurately correspond to each other, which is convenient for the insertion of the pin 102.

[0031] Of course, in order to form a sealed connection after the first joint 100 and the second joint 101 are butt-jointed, see Figure 2 As described above, the outer wall of the boss of the second joint 101 and the interior of the first joint 100 are provided with a plurality of annular grooves arranged along the axial direction, and a sealing ring 108 is provided in the annular groove. The structure of the multiple sealing rings 108 helps to improve the sealing performance of the first joint 100 and the second joint 101.

[0032] To summarize, the embodiment of the present application provides a quick-connect pipe joint, which can achieve rapid installation of the pipe joint by setting an elastic locking member on the connecting section of the first joint 100 and the second joint 101 that are plugged into each other, and using the elastic locking member pin 102 to lock the first joint 100 and the second joint 101 away from each other.

[0033] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
