Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1, a fast locking and releasing mechanism comprises a sleeve 1, a plunger 2, a locking plate 3, a cover 4, a first spring 5, a button 6, a second spring 7, a ball 9, a plunger groove 10 and a stopper 11, wherein the sleeve 1 is sleeved with the locking plate 3, the sleeve 1 is internally provided with the plunger 2 and a first stroke cavity, the first stroke cavity is internally provided with the first spring 5 and the button 6, the rear end of the plunger 2 is fixedly connected with the button 6, the first spring 5 is sleeved at the rear end of the plunger 2, one end of the first spring 5 is contacted with the button 6, the other end of the first spring is contacted with a limit table-board of the stroke cavity, the rear end of the sleeve 1 is sleeved with the cover 4, one end of the cover 4 is fixedly connected with the locking plate 3, the cover 4 is internally provided with the second stroke cavity, the second stroke cavity is internally provided with the second spring 7, one end of the second spring 7 is contacted with the locking plate 3, the other end is contacted with a spring seat 8 on the sleeve 1. The sleeve 1 is provided with a ball containing hole, a ball 9 is arranged in the ball containing hole, the inner diameter of the ball containing hole is gradually increased from outside to inside, and the diameter of the outermost side of the ball containing hole is smaller than that of the ball 9. And the plunger 2 is provided with a plunger groove 10 matched with the ball 9, and the plunger groove 10 is an annular groove.
The front end of plunger 2 is equipped with fender head 11, the width of fender head 11 is greater than the width of plunger 2, the front end of fender head 11 is circular-arc.
When the locking device is used, the stopper 11 is placed in a through hole of the locked plate 12 in an aligned mode (as shown in fig. 2), the button 6 is pressed, the sleeve 1 moves forwards, the balls fall into the plunger groove 10 (as shown in fig. 3), the button 6 is continuously pushed forwards, the front end of the sleeve 1 extends into the through hole of the locked plate 3 until the position of the balls 9 moves to the other side of the locked plate 12 (when the second spring 7 is completely compressed), the button 6 is released, the plunger moves backwards due to the elastic force of the first spring 5, the balls 9 are separated from the plunger groove 10, the balls 9 slide out, and the locked plate 12 is locked (as shown in fig. 4); when unlocking, the button 6 is pressed, the plunger 2 moves forwards, the ball 9 falls into the plunger groove 10 and is unlocked by the locking plate 12 (as shown in fig. 5), and the front end of the sleeve 1 can exit from the through hole of the locking plate 12 through the elastic force of the second spring 7, so that quick release is realized.
