The connecting end 62 of the unlocking key 6 abuts against the second connecting piece 31 of the mounting seat 3.

The two second connection pieces 63 of the unlocking key 6 are located between the two first connection pieces 15, the first fixing holes 11 and the fourth fixing holes 64 correspond to each other, and the first plug pin 7 is simultaneously inserted into the two first fixing holes 11 and the two fourth fixing holes 64, so that the unlocking key 6 is rotationally connected with the handle 1. The two third connecting pieces 31 are located between the two first connecting pieces 15, the third fixing holes 13 and the fifth fixing holes 32 correspond to each other, and the third bolt 9 is simultaneously inserted into the two third fixing holes 13 and the two fifth fixing holes 32, so that the handle 1 and the mounting seat 3 are connected in a rotating manner. The second bolt 8 is inserted into the second fixing hole 12, and two ends of the second bolt 8 extend out of the second fixing hole 12, so that the connecting holes at two ends of the second bolt 8 are respectively connected with the two grippers 5.

Further, the snap lock 100 further includes a positioning pin 2, the mounting base 3 is provided with a positioning hole 33, the positioning pin 2 is mounted in the positioning hole 33, and one end of the positioning pin 2 passes through the positioning hole 33. A first spring 17 is arranged between the other end of the locating pin 2 and the connecting seat 16 of the handle 1. The locating pin 2 is abutted against one side of the box body A200, and a clamping hole is formed in a corresponding position of the box body A200 and used for fixing the locating pin 2, so that the quick lock 100 with the locating and fixing hasp can be used.

The clamping seat 4 is provided with a clamping groove 41, and the gripper clamping pin 53 is clamped in the clamping groove 41.

The operation of the snap lock 100 of the present application will be further described below:

when the LED box a200 and the LED box B300 need to be spliced, the LED box a and the LED box B are attached together, the mount pad 3 is fixed on the LED box 200, the card holder 4 is fixed on the LED box B300, the mount pad 3 corresponds to the card holder 4, the snap-lock 100 is in the state shown in fig. 9, as shown in fig. 9, and then the grip 5 is rotated in the direction of the card holder 4, that is, in the arrow AB direction in the drawing, until the grip bayonet lock 53 is snapped into the card slot 41 on the card holder 4, and the snap-lock 100 is in the state shown in fig. 10. As shown in fig. 10, after that, the handle 1 is rotated in a direction away from the card holder 4, that is, in the EF direction, along with the rotation of the handle 1, the connection end 62 of the unlocking key 6 moves down until the connection end abuts against the mounting seat 3, and the pressing end 61 of the unlocking key 6 gradually extends out of the unlocking hole 10 until the handle 1 cannot rotate any more due to the blocking of the LED box a200, at this time, the snap lock 100 is in the state shown in fig. 3, and the handle 1 pulls the grip 5 to fasten the grip bayonet 53 in the bayonet 41, so that the LED box a200 and the LED box B300 are fixedly connected. The connecting end 62 of the unlocking key 6 is abutted against the mounting seat 3, so that the handle 1 can be prevented from rotating towards the FE direction accidentally, and the pull force of the handle 1 to the handle 5 is prevented from being lost, so that the handle bayonet lock 53 is prevented from being separated from the clamping seat 4, and the splicing reliability can be improved through the unlocking key 6.

When the LED case a200 and the LED case B300 need to be detached, only the pressing end 61 of the unlocking key 6 is pressed downward, so that the connecting end 62 is separated from the mounting seat 3, the restriction on the handle 1 can be released at this time, then, as shown in fig. 3, the handle 1 is rotated in the FE direction, the pulling force of the handle 1 on the grip 5 disappears as the handle 1 rotates, and the grip 5 moves toward the front of the card holder 4 under the pushing of the handle 1, so that the grip bayonet 53 is separated from the card slot 41, and then, the grip 5 is rotated in the BA direction, so that the grip 5 is separated from the LED case B300, thereby separating the LED case a200 and the LED case B300.
