Detailed ways

A specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

As shown in Figures 1 to 6, a fast fastening and separation connection device provided by an embodiment of the present invention includes: a first connection module, which includes a cylindrical first connection piece 10 with an end, a first spring 11. Movable lock sleeve 12, second spring 13 and retractable lock head 15. The first connector 10 is provided with a storage groove along the axis direction for accommodating the movable lasso. One end of the first spring 11 is connected to The other end of the movable lock sleeve 12 is connected in the receiving groove; the first connector 10 is provided with a lock groove 14 for accommodating the retractable lock head 15, and one end of the second spring 13 is connected to On the telescopic lock head 15, the other end is connected in the lock head groove 14; the second connection module includes a second connecting piece 20 and a reset button 22 arranged on the second connecting piece 20, so The second connector 20 is provided with a mounting hole, the end of the first connector 10 away from the end can extend into the mounting hole, and the reset button 22 is used to squeeze the telescopic lock head 15 So that the telescopic lock 15 is completely located in the lock slot 14, the second connecting piece 20 is provided with a positioning hole for accommodating the telescoping lock 15, when the second connecting piece 20 is sleeved When on the first connecting member 10 , the retractable lock head 15 can extend into the positioning hole to position the second connecting member 20 .

The lock groove 14 is provided with a fixed rod 16, the telescopic lock 15 is provided with a blind hole for receiving the fixed rod 16, the telescopic lock 15 is sleeved on the fixed rod 16 and passed through The second spring 13 is connected in the locking groove 14 .

The locking groove 14 is opened symmetrically with respect to the axis of the first connecting member 10 .

A button groove is opened through the second connecting piece 20, and the reset button 22 is slidably disposed in the button groove. A wing plate is arranged on the reset button 22, and one end of the third spring 21 is connected to the The other end of the second connecting piece 20 is connected to the wing plate.

Specifically, the connector module is composed of a first connector 10, a first spring 11, a movable lock sleeve 12, a second spring 13, a lock groove 14, and a retractable lock 15. The first spring 11 is fixed to the first connector 10. Connected, also fixedly connected with the movable lock sleeve 12, the movable lock sleeve 12 moves on the track 23 of the first connector 10, the second spring 13 connects the first connector 10 and the lock head, and the telescopic lock head 15 is on the second Driven by the spring 13, it moves on the fixed rod 16.

The second connector 20 module is made up of a second connector 20, a third spring 21, and a reset button 22. The third spring 21 is affixed to the second connector 20 and is also affixed to the reset button 22; the reset button 22 is located at the second connector 20. In a cavity of the second connecting part 20, and the reset button 22 is also locked by the second connecting part 20 in four degrees of freedom, front, rear, left, right, and only allowed to move up and down within a range.

Fastening and separation process: when not connected, the reset button 22 of the second connecting part 20 is positioned under the restriction of the third spring 21, and the first spring 11 of the first connecting part 10 pushes out the movable lock sleeve 12, and the movable The lock sleeve 12 compresses the retractable lock head 15 into the lock head groove 14 and is in a closed state. When connecting, press the reset button 22 on the second connecting piece 20, the retractable lock head 15 is not allowed to enter the housing of the second connecting piece 20, and then use the second connecting piece 20 to be inserted into the first connecting piece 10 and push The movable lock sleeve 12 compresses the movable lock sleeve 12 into the inside of the first connector 10 along the track 23. At this moment, there is no gap between the movable lock sleeve 12 and the second connector 20 (for the telescopic lock head 15 to be able to enter the housing of the second connector 20); when the telescopic lock 15 enters the central through hole of the second connector 20 smoothly, the reset button 22 is released, and the second connector 20 is manually rotated to make the telescopic lock 15 Enter the shell of the second connecting piece 20 smoothly, and the connection is completed. To take it off, just press the reset button 22 and pull out the second connecting piece 20 .
