Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a self-sealing quick connector that is easy to snap into place. Background Technology

[0002] Quick couplings are devices used to quickly connect and disconnect fluid transmission lines, widely used in hydraulic systems, pneumatic systems, and various piping systems requiring frequent replacement or maintenance. They consist of two main parts: a plug and a socket, achieving a sealed connection through simple push-pull or rotation actions without the need for tools, greatly improving work efficiency and convenience.

[0003] In existing technologies, many quick connectors require tools or multiple rotations and presses to lock and unlock during connection. This not only increases the complexity of operation and can easily lead to a decrease in connection strength, but also reduces work efficiency.

[0004] Therefore, we propose a self-sealing quick connector that is easy to snap into place. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art and provide a self-sealing quick connector that is easy to snap into place.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a self-sealing quick connector that is easy to snap into place, comprising a male connector assembly, a female connector assembly at the bottom of the male connector assembly, the male connector assembly including a male connector body, a tapered insertion tube fixedly installed at the bottom of the male connector body, a first locking component on the left side wall of the male connector body, and a second locking component on the right side wall of the male connector body, the structure of the second locking component being the same as that of the first locking component; the female connector assembly including a female connector body, the top of the female connector body being in movable contact with the bottom of the male connector body.

[0007] Preferably, the first locking component includes an elastic claw, and the upper end of the right side wall of the elastic claw is fixedly connected to the left side wall of the male head body.

[0008] Preferably, a sealing ring is fixedly installed on the top of the female head body, and the top of the sealing ring is in contact with the bottom of the male head body.

[0009] Preferably, a protruding locking block is fixedly installed on the lower right side wall of the elastic claw.

[0010] Preferably, the inner wall of the female head body is provided with a self-sealing valve.

[0011] Preferably, the self-sealing valve includes a valve body, and the outer wall of the valve body is fixedly connected to the inner wall of the female head body.

[0012] Preferably, a spring is fixedly installed on the inner wall of the valve body.

[0013] Preferably, a valve core is fixedly mounted on the top of the spring, and the outer wall of the valve core is movably connected to the upper end of the inner wall of the valve body.

[0014] Preferably, the outer wall of the female head body is provided with a locking groove, and the inner wall of the female head body is located at the locking groove and is movably engaged with the outer wall of the outwardly protruding locking block.

[0015] This invention provides a self-sealing quick connector that is easy to snap into place. It has the following advantages:

[0016] 1. This self-sealing quick connector, which facilitates snap-fit ​​connection, consists of a male and a female assembly. When connecting pipes, simply insert the tapered tube at the bottom of the male assembly into the female assembly. The tapered tube then compresses the valve core inside the self-sealing valve, causing the valve core to move upward under the action of a spring. When the tapered tube is fully inserted into the female assembly, the protruding locking blocks in the first and second locking assemblies engage with the locking groove on the outer wall of the female assembly, thus locking the male and female assemblies and completing the pipe connection. When disassembling the pipes, simply pull out the elastic claw to disengage the protruding locking block from the locking groove, allowing the male and female assemblies to be separated. The operation is convenient and quick, greatly saving the user's time and improving the sealing performance of the pipe connection.

[0017] 2. This easy-to-connect self-sealing quick connector features a tapered tube and a self-sealing valve. When the tapered tube is inserted into the female connector assembly, its outer wall comes into close contact with the valve core of the self-sealing valve, thus opening the passage of the female connector assembly. Simultaneously, the valve core of the self-sealing valve automatically resets under the action of a spring. When the tapered tube is pulled out, the valve core quickly seals the opening of the female connector assembly, preventing fluid leakage and ensuring the safety and stability of the pipeline system.

[0028] Example 1: A self-sealing quick connector that is easy to snap into place, such as... Figures 1-2 As shown, the device includes a male connector assembly 10, with a female connector assembly 11 at its bottom. The male connector assembly 10 includes a male connector body 12, with a tapered insertion tube 13 fixedly installed at the bottom of the male connector body 12. A first locking assembly 14 is provided on the left side wall of the male connector body 12, and a second locking assembly 15 is provided on the right side wall of the male connector body 12. The structure of the second locking assembly 15 is the same as that of the first locking assembly 14. The first locking assembly 14 includes an elastic claw 16, with the upper end of the right side wall of the elastic claw 16 fixedly connected to the left side wall of the male connector body 12. A protruding locking block 17 is fixedly installed at the lower end of the right side wall of the elastic claw 16. By setting up the male connector assembly 10 and the female connector assembly 11, when it is necessary to connect the pipe, only the male connector assembly needs to be connected. The tapered tube 13 at the bottom of component 10 is inserted into the female connector assembly 11. At this time, the tapered tube 13 squeezes the valve core in the self-sealing valve 20, causing the valve core to move upward under the action of the spring. When the tapered tube 13 is fully inserted into the female connector assembly 11, the protruding locking block 17 in the first locking assembly 14 and the second locking assembly 15 engages with the locking groove 21 opened on the outer wall of the female connector body 18, thereby locking the male connector assembly 10 and the female connector assembly 11 and completing the connection of the pipe. When it is necessary to separate the pipe, simply pull the elastic claw 16 outward to disengage the protruding locking block 17 from the locking groove 21, and then the male connector assembly 10 and the female connector assembly 11 can be separated. The operation is convenient and quick, greatly saving the user's time, and improving the sealing of the pipe connection.

[0029] Example 2: Based on Example 1, as follows Figure 3As shown, the female connector assembly 11 includes a female connector body 18, with the top of the female connector body 18 in movable contact with the bottom of the male connector body 12. A sealing ring 19 is fixedly installed on the top of the female connector body 18, and the top of the sealing ring 19 is in movable contact with the bottom of the male connector body 12. A self-sealing valve 20 is provided on the inner wall of the female connector body 18. By providing a conical insertion tube 13 and a self-sealing valve 20, when the conical insertion tube 13 is inserted into the female connector assembly 11, the outer wall of the conical insertion tube 13 is in close contact with the valve core of the self-sealing valve 20, thereby opening the channel of the female connector assembly 11. At the same time, the valve core of the self-sealing valve 20 can automatically reset under the action of the spring. When the conical insertion tube 13 is pulled out, the valve core can quickly close the opening of the female connector assembly 11 to prevent fluid leakage and ensure the safety and stability of the pipeline system.

[0030] Example 3: Based on Examples 1 and 2, as follows... Figure 3 As shown, the self-sealing valve 20 includes a valve body, and the outer wall of the valve body is fixedly connected to the inner wall of the female head body 18. A spring is fixedly installed on the inner wall of the valve body, and a valve core is fixedly installed on the top of the spring. The outer wall of the valve core is movably connected to the upper end of the inner wall of the valve body. A locking groove 21 is provided on the outer wall of the female head body 18, and the inner wall of the female head body 18 is located at the locking groove 21 and is movably engaged with the outer wall of the protruding locking block 17.

[0031] The working principle of this utility model is as follows: When it is necessary to connect the pipes, simply insert the tapered tube 13 at the bottom of the male connector assembly 10 into the female connector assembly 11. At this time, the tapered tube 13 squeezes the valve core in the self-sealing valve 20, causing the valve core to move upward under the action of the spring. When the tapered tube 13 is fully inserted into the female connector assembly 11, the protruding locking block 17 in the first locking assembly 14 and the second locking assembly 15 engages with the locking groove 21 opened on the outer wall of the female connector body 18, thereby locking the male connector assembly 10 and the female connector assembly 11 and completing the pipe connection. When it is necessary to disassemble the pipes, simply pull the elastic claw 16 outward to disengage the protruding locking block 17 from the locking groove 21, and then the male connector assembly 10 and the female connector assembly 11 can be disassembled. The operation is convenient and quick, greatly saving the user's time, and improving the sealing performance of the pipe connection.
