Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 This utility model provides a technical solution: a connector mechanism for a pneumatic component, including a male connector 1, a female connector 2, a protrusion 3 for quick positioning and installation, and a locking nut 4 for preventing detachment. The male connector 1 and the female connector 2 are detachably connected. The inner wall of the female connector 2 is provided with a conical groove that matches the surface of the male connector 1. An air outlet element 5 for outputting gas is fixedly connected to the female connector 2. The protrusion 3 is fixedly connected to the male connector 1. By providing the protrusion 3 and the L-shaped hole 6, it is convenient for the male connector 1 and the female connector 2 to be quickly positioned and inserted.

[0024] The female head 2 is provided with an L-shaped hole 6 that moves with the protrusion 3. The male head 1 is fixedly connected with an outer ring 7. The anti-reverse nut 4 is threadedly connected to the outer ring 7. The female head 2 is provided with an airlock assembly 8 for automatic air closure. The male head 1 is provided with an ejector rod 9 for opening the airlock assembly 8. By setting the outer ring 7 and the anti-reverse nut 4, it is easy to prevent the connector mechanism from falling off after installation.

[0025] The airlock assembly 8 includes a sealing block 801, on which a vent hole 802 for gas output is provided, and a movable groove 803 is provided on the sealing block 801. A self-locking block 804 for blocking the vent hole 802 is provided on the movable groove 803. By setting the sealing block 801, the self-locking block 804, the spring 813 and the fixing block 806, the female connector 2 can automatically close the air and avoid gas leakage before installation.

[0026] A connecting rod 805 is fixedly connected to the self-locking block 804. A fixing block 806 is sleeved on the connecting rod 805. A spring 813 is provided inside the fixing block 806. The spring 813 is fixedly connected to the connecting rod 805. A longitudinal rod 807 is fixedly connected to the fixing block 806, and the longitudinal rod 807 is fixedly connected to the female head 2.

[0027] The vent 802 has a sleeve 808 inside, and a round rod 810 inside the sleeve 808. The sleeve 808 has a spiral hole 809. A driven block 811 is fixedly connected to the round rod 810, and the driven block 811 is adapted to the spiral hole 809. The sealing block 801 has a support frame 812 for fixing the sleeve 808. By setting the sleeve 808, driven block 811, spiral hole 809 and round rod 810, it is convenient to bear the force applied to the male head 1 by the installer, so that the round rod 810 pushes out the self-locking block 804.

[0028] The male head 1 is provided with a fixing rod 11 inside, and the ejector rod 9 is fixedly connected to the fixing rod 11. By setting the fixing rod 11 and the ejector rod 9, it is convenient to receive the force applied by the personnel to rotate the male head 1 during the installation of the connector and to open the airlock assembly 8.

[0029] The ejector rod 9 has a rectangular cross-section. The end of the round rod 810 away from the self-locking block 804 has a rectangular groove that matches the ejector rod 9. The ejector rod 9 is inserted into the round rod 810. The anti-reverse nut 4 is provided with a sealing ring 10 to increase airtightness. Thus, the pneumatic component connector mechanism has the effect of quick installation and preventing detachment.

[0030] Working principle: First, insert the male head 1 into the female head 2. Insert the protrusion 3 horizontally along the L-shaped hole 6. At the same time, the ejector rod 9 is inserted into the round rod 810. Then, rotate the male head 1, which drives the protrusion 3 to rotate, so that the male head 1 and the female head 2 are locked together. The rotation of the male head 1 drives the fixed rod 11 to rotate, which in turn drives the ejector rod 9 to rotate, which in turn drives the round rod 810 to rotate. The round rod 810 is supported by the sleeve 808, and the driven block 811 on the round rod 810 is limited by the spiral hole 809. The round rod 810 moves horizontally when rotating. Then, the round rod 810 moves to the side of the self-locking block 804 and drives the self-locking block 804 to move away from the vent hole 802. The air outlet element 5 outputs gas to the connector. The gas is output to the female head 2 through the vent hole 802. The locking of the male head 1 and the female head 2 can temporarily overcome the sudden air pressure output and prevent the connector from falling off during installation.

[0031] Then, the anti-reverse nut 4 is threaded to the outer ring 7 to make the male head 1 and female head 2 more tightly connected, and at the same time increase the airtightness between the male head 1 and female head 2. Then the joint mechanism is installed and can prevent the joint from falling off. Thus, the pneumatic component joint mechanism has the effect of quick installation and preventing falling off.
