[0055] Specifically, a handle connector 11 is integrally formed on the side wall of the valve body 1, and a first installation channel 111 and a second installation channel 112 are provided on the handle connector 11. The connection end of the handle assembly 3 passes through the first installation channel 111 and is connected to the valve core 5; the second installation channel 112 is connected to the connection groove 21, and the limit assembly 4 is installed in the second installation channel 112;

[0057] A steel wire socket 13 is also provided on the side wall of the valve body 1 , and an annular groove 131 for installing a steel wire 8 is provided on the inner wall of the valve body 1 . The steel wire socket 13 corresponds to the annular groove 131 , and the steel wire 8 is used to limit the tail end piece 6 .

[0058] Specifically, the handle connector 11 is further provided with a first limiting hole 113 and a second limiting hole 114 for limiting the handle assembly 3 .

[0059] Specifically, the handle assembly 3 includes an inner knob block 31 and an outer knob block 32. A protrusion 311 is arranged at the center of the inner knob block 31. The body of the protrusion 311 is rotatably arranged in the first installation channel 111. The protrusion 311 and the valve core 5 are snap-fitted. A bolt 33 is threadedly connected to the inner knob block 31. The body of the bolt 33 is threadedly connected to the valve core 5 after passing through the reserved through hole in the center of the protrusion 311.

[0060] The inner knob block 31 is provided with a first magnetic ring 34, and the outer knob block 32 is provided with a second magnetic ring 35. The inner knob block 31 and the outer knob block 32 are adsorbed together by the two magnetic rings. A limiting screw 36 is provided on the inner knob block 31, and the other end of the limiting screw 36 is connected to the third limiting hole 321 of the outer knob block 32.

[0061] The outer knob block 32 is provided with a first limiting pin 37 , which corresponds to the first limiting hole 113 and the second limiting hole 114 , respectively. The inner knob block 31 is provided with a through hole for passing the first limiting pin 37 .

[0062] Specifically, the limiting assembly 4 includes a third magnetic ring 41 and a second limiting pin 42, the third magnetic ring 41 is pasted in the second installation channel 112, an iron block 421 is installed on the body of the second limiting pin 42, and the iron block 421 is adsorbed on the third magnetic ring 41;

[0063] An arc groove 312 is provided on the inner knob block 31, one end of the arc groove 312 is connected to the limit pin insertion port 313, one end of the second limit pin 42 is located in the connecting groove 21, and the other end is half embedded in the limit pin insertion port 313. When the two valve bodies 1 are connected together through the interlocking assembly 2, the hook foot 22 on one of the valve bodies 1 pushes the second limit pin 42 on the other valve body 1 out of the connecting groove 21. At this time, the end portion of the second limit pin 42 is completely embedded in the limit pin insertion port 313.

[0064] Interlocking principle: when operating a single connector with a self-locking function, that is, when connecting the tail end piece 6 on a single ball valve to the liquid circulation pipeline, under the action of the third magnetic ring 41, the iron block 421 on the second limit pin 42 is adsorbed on the third magnetic ring 41. At this time, the inner end side of the second limit pin 42 is located in the connecting groove 21, and the outer end side is half embedded in the limit pin insertion port 313. At this time, the second limit pin 42 cannot slide in the arc groove 312, and the second limit pin 42 completes the limiting effect on the inner knob block 31 to prevent the inner knob block 31 from rotating. At this time, the valve core 5 is in a blocked state, which can avoid liquid leakage caused by the operator's incorrect rotation of the handle assembly 3, thereby improving the safety of the connector with a self-locking function.

[0065] When two connectors with self-locking function are interlocked and connected together, the hook foot 22 on one valve body 1 pushes the second limit pin 42 on the other valve body 1 out of the connecting groove 21. At this time, the end of the second limit pin 42 is completely embedded in the limit pin insertion port 313, and the second limit pin 42 can slide in the arc groove 312. The operator can rotate the handle assembly 3 so that the liquid can flow in the pipeline.

[0066] In the specific implementation, in order to facilitate the hook foot 22 to push the second limit pin 42 out of the connecting groove 21, the abutting surface between the hook foot 22 and the second limit pin 42 is set to be an arc shape. When the two connectors with self-locking function rotate and interlock, the hook foot 22 pushes the second limit pin 42 out of the connecting groove 21.

[0067] Specifically, those skilled in the art may also replace the third magnetic ring 41 with a spring, connect the iron block 421 and the second installation channel 112 with the spring, and enable the spring to provide the second limiting pin 42 with the force required for resetting.

[0068] Specifically, the stabilizing assembly 7 includes a spring 71 and a sleeve 72, the sleeve 72 is sleeved on the spring 71, one end of the spring 71 abuts against the inner wall of the third mounting channel 121, and the other end abuts against the sleeve 72, the body of the sleeve 72 is movably connected in the third mounting channel 121, and the sleeve 72 and the valve core 5 are rotationally connected.

[0069] Specifically, the tail piece 6 is connected to two O-rings for sealing.

[0070] Specifically, the protrusion 311 and the bolt 33 are both sleeved with O-rings for sealing.

[0071] Specifically, a sealing ring 14 is installed at the bottom of the valve body 1 .

[0072] There are two sealing rings 14 , one for sealing between the valve core 5 and the valve body 1 , and the other for sealing between two different valve bodies 1 .

[0073] The working principle of the connector with self-locking function of the present invention is as follows:

[0074] Interlocking principle: when operating a single connector with a self-locking function, that is, when connecting the tail end piece 6 on a single ball valve to the liquid circulation pipeline, under the action of the third magnetic ring 41, the iron block 421 on the second limit pin 42 is adsorbed on the third magnetic ring 41. At this time, the inner end side of the second limit pin 42 is located in the connecting groove 21, and the outer end side is half embedded in the limit pin insertion port 313. At this time, the second limit pin 42 cannot slide in the arc groove 312, and the second limit pin 42 completes the limiting effect on the inner knob block 31 to prevent the inner knob block 31 from rotating. At this time, the valve core 5 is in a blocked state, which can avoid liquid leakage caused by the operator's incorrect rotation of the handle assembly 3, thereby improving the safety of the connector with a self-locking function.

[0075] When two connectors with self-locking function are interlocked and connected together, the hook foot 22 on one valve body 1 pushes the second limit pin 42 on the other valve body 1 out of the connecting groove 21. At this time, the end of the second limit pin 42 is completely embedded in the limit pin insertion port 313, and the second limit pin 42 can slide in the arc groove 312. The operator can rotate the handle assembly 3 so that the liquid can flow in the pipeline.

[0076] Anti-foolproof principle: when rotating the handle assembly 3, pull the outer knob block 32 outward, and the outer knob block 32 drives the first limit pin 37 to leave the first limit hole 113 or the second limit hole 114. At this time, rotate the outer knob block 32, the outer knob block 32 drives the inner knob block 31 to rotate, and the inner knob block 31 drives the valve core 5 to rotate. When the first limit pin 37 is aligned with the second limit hole 114 or the first limit hole 113, release the outer knob block 32. The outer knob block 32 is adsorbed on the inner knob block 31 under the action of the suction force of the two magnetic rings. At this time, the first limit pin 37 is inserted into the second limit hole 114 or the first limit hole 113 to complete the limiting of the handle assembly 3.
