[0006] The leak-free quick-connect connector provided in this application adopts the following technical solutions:

[0007] A leak-free quick-connect connector includes a female connector and a male connector, wherein the female connector is provided with a connecting assembly connected to the male connector, the connecting assembly including a connecting pipe sleeved on the female connector port, the connecting pipe having four annular cavities defined therein, the inner wall of the connecting pipe being provided with insertion rods located at the cavities, one end of each insertion rod being located in the cavities and fixedly connected to a connecting plate, the side wall of the connecting plate away from the insertion rods being fixedly connected to two parallel first springs, the end of each first spring away from the connecting plate being fixedly connected to the side wall of the cavity, the side wall of the male connector being provided with a plurality of sockets respectively adapted for the insertion rods, a push block being fixedly connected to one side wall of the connecting plate below the insertion rods, the end of the push block away from the connecting plate penetrating the side wall of the cavity and forming a sliding connection, the bottom end of the connecting pipe being rotatably connected to a swivel, the inner side wall of the swivel being fixedly connected to a pressure block for pressing the push block into the cavity, the pressure blocks being located on one side of the push block, and the side wall of the pressure block opposite to the push block being provided with a guide slope.

[0008] By adopting the above technical solution, when in use, the rotating ring is rotated to drive the pressure block to rotate, so that the pressure block contacts the push block, squeezes the push block, and moves the push block toward the cavity, squeezes the connecting plate, contracts the first spring, moves the insertion rod into the cavity, and then docks the male connector with the female connector, and then rotates the rotating ring to move the pressure block away from the push block, so that the first spring rebounds and pushes the insertion rod out, so that the insertion rod is inserted into the socket, and the male connector and the female connector are connected, thereby avoiding as much as possible the problem that the button may be accidentally pressed under the influence of external factors, resulting in accidental disconnection of the connector.

[0009] Preferably, a first flange is fixedly connected to the bottom end of the female connector, a first sealing plug for sealing the female connector port is sealed and plugged into the first flange, the first sealing plug is slidably connected to the first flange, a second spring is sleeved on the first sealing plug, and the two ends of the second spring are respectively fixedly connected to the first sealing plug and the first flange, a second flange is fixedly connected to the top end of the male connector, a sealing sleeve is slidably provided at the bottom end of the male connector, a third spring is fixedly connected between the sealing sleeve and the second flange, and a second sealing plug for sealing the sealing sleeve is fixedly connected to the lower surface of the second flange.

[0010] By adopting the above technical solution, when the female connector and the male connector are connected, the female connector will be inserted into the male connector to push the sealing sleeve, causing the third spring to contract, so that the second sealing plug is separated from the sealing sleeve, and the port of the male connector is opened. At the same time, the second sealing plug will push the first sealing plug, causing the second spring to contract, so that the first sealing plug opens the port of the female connector and forms a passage. When disconnected, the third spring rebounds to cause the second sealing plug to seal the sealing sleeve, and at the same time, the second spring rebounds to cause the first sealing plug to seal the port of the female connector, so that there is a leakage-free effect during disassembly and installation.

[0011] Preferably, a first sealing gasket is fixedly connected to the bottom end of the sealing sleeve.

[0012] By adopting the above technical solution, the sealing performance of the connection between the female connector and the male connector can be improved by the first sealing gasket to prevent leakage.

[0017] Preferably, the push block and the insertion rod have the same length.

[0018] By adopting the above technical solution, it is prevented that after the push block moves into the cavity, part of the insertion rod is still located outside the cavity, which affects the connection between the female connector and the male connector.

[0019] Preferably, a bellows is provided in the third spring, and two ends of the bellows are fixedly connected to the sealing sleeve and the second flange respectively.

[0020] By adopting the above technical solution, the bellows can prevent the passing liquid from contacting the third spring, thereby increasing the service life of the third spring.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The present application is provided with a coordinated arrangement among the structures such as the insertion rod, the push block and the rotating ring. When in use, the rotating ring is rotated to drive the pressure block to rotate, so that the pressure block contacts the push block, squeezes the push block, moves the push block toward the cavity, squeezes the connecting plate, contracts the first spring, moves the insertion rod into the cavity, and then docks the male connector with the female connector. The rotating ring is then rotated to move the pressure block away from the push block, so that the first spring rebounds and pushes the insertion rod out, so that the insertion rod is inserted into the socket, and the male connector and the female connector are connected, thereby minimizing the problem that the button may be accidentally pressed due to external factors, resulting in accidental disconnection of the connector.

[0023] 2. When connecting the female connector and the male connector, the female connector will be inserted into the male connector to push the sealing sleeve, causing the third spring to contract, so that the second sealing plug will be separated from the sealing sleeve and the port of the male connector will be opened. At the same time, the second sealing plug will push the first sealing plug, causing the second spring to contract, so that the first sealing plug will open the port of the female connector and form a passage. When disconnecting, the third spring will rebound so that the second sealing plug will seal the sealing sleeve. At the same time, the second spring will rebound so that the first sealing plug will seal the port of the female connector, so that there is no leakage during disassembly and installation.
