The outlets of the male head and the female head are blocked by the first sealing sheet and the second sealing sheet, so that the male head and the female head can be bidirectionally closed when they fall off, thereby achieving the effect of preventing internal material from leaking. When connecting, after the male head and the female head are plugged in, the clamping ring can be rotated to make the clamping block at the side end of the clamping ring clamp the female head, so as to complete the quick fixation. During use, when the first slide bar slides, the first inclined groove on the first slide bar is constrained by the two plug rods inside the male head, which will cause the first slide bar and the first sealing sheet to rotate 30 degrees, so that the petal-shaped notches on the male head and the first sealing sheet correspond to each other, and the second When the slide rod is sliding, the second inclined groove on the second slide rod is constrained by the two plug rods inside the female head, which will cause the second slide rod and the second sealing sheet to rotate thirty degrees, so that the petal-shaped notches on the female head and the second sealing sheet correspond to each other. When the material flowing inside the male head and the female head flows, it can flow directly from one notch to another. The first sealing sheet and the second sealing sheet are rotated through the first inclined groove and the second inclined groove, so that the internal material can flow directly without obstruction, thereby achieving the effect of reducing the impact of the flowing material on the connecting head and increasing the material flow speed. Example

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that if the internal pressure of the pipeline is too high during use, the quick connector will cause the connector to fall off, causing the substance in the pipeline to leak. The overall idea is as follows:

[0023] In view of the problems existing in the prior art, the utility model provides a special quick connector with a self-sealing function, including a male head 1 and a female head 2, a first slide bar 11 is slidably installed inside the male head 1, a first sealing sheet 12 is fixedly installed on the side end of the first slide bar 11, and a second slide bar 21 is slidably installed inside the female head 2.

[0024] A second sealing sheet 22 is fixedly mounted on the side end of the second slide bar 21 , two first inclined grooves 14 are symmetrically provided on the first slide bar 11 , a first spring 13 is fixedly mounted on the outer side wall of the first slide bar 11 , and a second inclined groove 24 is provided on the second slide bar 21 .

[0025] A second spring 23 is fixedly mounted on the outer side wall of the second slide bar 21 , a top plate 25 is fixedly mounted on the side end of the second slide bar 21 , a top rod 26 is fixedly mounted on the side end of the second slide bar 21 , and a snap ring 3 is rotatably mounted on the outer side wall of the male connector 1 .

[0026] Working principle:

[0027] The first step is to connect and insert the male connector 1 and the female connector 2 during use. The side end of the male connector 1 will first abut against the top plate 25, and the male connector 1 will push the top plate 25 to slide. The top plate 25 will push the second sealing sheet 22 to slide through the second slide bar 21, so that the second sealing sheet 22 will be separated from the outlet of the female connector 2. During this process, the second slide bar 21 will compress the second spring 23 to store force for the second spring 23. At the same time, the top rod 26 will abut against the first slide bar 11, and the top rod 26 will push the first slide bar 11 to slide. The first slide bar 11 pushes the first sealing sheet 12 to separate the first sealing sheet 12 from the outlet of the male connector 1. During this process, the first slide bar 11 will compress the first spring 13 to make the first spring 1 3 accumulates force. When the outlets of the male head 1 and the female head 2 are both opened, the material can be transmitted through the male head 1 and the female head 2. When the male head 1 and the female head 2 fall off, the first slide bar 11 will lose the restraint of the top rod 26, and the top plate 25 will lose the restraint of the male head 1. The elastic force of the first spring 13 and the second spring 23 is released, which will push the first slide bar 11 and the second slide bar 21 to slide, so that the first sealing sheet 12 and the second sealing sheet 22 block the outlets of the male head 1 and the female head 2 to complete the interception. The outlets of the male head 1 and the female head 2 are blocked by the first sealing sheet 12 and the second sealing sheet 22, so that the male head 1 and the female head 2 can be bidirectionally closed when they fall off, thereby achieving the effect of preventing internal material leakage.

[0028] In the second step, when connecting, after the male head 1 and the female head 2 are inserted, the snap ring 3 can be rotated to make the block at the side end of the snap ring 3 clamp the female head 2 to complete the quick fixation. During use, when the first slide bar 11 is sliding, the first inclined groove 14 opened on the first slide bar 11 is constrained by the two plug rods inside the male head 1, which will cause the first slide bar 11 and the first sealing sheet 12 to rotate 30 degrees, so that the petal-shaped notches on the male head 1 and the first sealing sheet 12 correspond to each other. When the second slide bar 21 is sliding, the second inclined groove 2 Constrained by the two plug rods inside the female head 2, the second slide bar 21 and the second sealing sheet 22 are rotated thirty degrees, so that the petal-shaped notches on the female head 2 and the second sealing sheet 22 correspond to each other. The material flowing inside the male head 1 and the female head 2 can flow directly from one notch to another, and the first sealing sheet 12 and the second sealing sheet 22 are rotated through the first inclined groove 14 and the second inclined groove 24, so that the internal material can flow directly without obstruction, thereby achieving the effect of reducing the impact of the flowing material on the connector and increasing the material flow speed.

[0029] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
