Thus, the handle 40, the clamping mechanism 50, the lock shaft 30, the lock base 20 and the lock pin 10 are matched with each other, and the clamping mechanism 50 can clamp the lock pin 10 only by rotating the handle 40, so that the first LED box 61 and the second LED box 62 are connected, the operation mode is simple, the clamping mechanism 50 is ensured to clamp the lock pin 10 when the lock shaft 30 is in the locking position, and the first LED box 61 and the second LED box 62 are firmly connected. The technical scheme of the application effectively solves the problems that the mode of connecting the box body by using the bolts in the related technology is complex in operation and low in assembly efficiency.
As shown in fig. 1, 2, 3, 9 and 10, each of the first and second clamping members 51 and 52 includes a fitting portion 53, a claw portion 54, and a pivot portion 55 disposed between the fitting portion 53 and the claw portion 54, the pivot portion 55 being pivotally connected to the base 21, the fitting portion 53 having an arc-shaped notch 531 to be fitted to the second end of the lock shaft 30, the claw portion 54 being fitted to the lock pin 10. With the above structure, the first clamping member 51 and the second clamping member 52 are provided with the matching portion 53, the claw portion 54 and the pivoting portion 55, and the pivoting portion 55 is pivotally connected with the base 21, so that the first clamping member 51 and the second clamping member 52 can both rotate under the action of the pivoting portion 55, so that the lock shaft 30 can be matched with the matching portion 53, and the claw portion 54 is matched with the lock pin 10. The second end of the lock shaft 30 is inserted into the receiving cavity 211 to be engaged with the arc-shaped notch 531 of the engaging portion 53, so that the jaw portion 54 of the first clamping member 51 and the jaw portion 54 of the second clamping member 52 are brought close to each other to be capable of clamping the lock pin 10. After the lock shaft 30 is moved away from the receiving cavity 211, the claw portions 54 of the first clamping member 51 and the claw portions 54 of the second clamping member 52 are no longer restrained, they can be moved away from each other to release the lock pin 10 by the clamping mechanism 50. The lock shaft 30 stretches into or leaves the arc notch 531 to drive the claw portion 54 of the first clamping piece 51 and the claw portion 54 of the second clamping piece 52 to approach or depart from each other, so as to clamp or release the lock pin 10, and the clamping structure is ensured to be stable.
As shown in fig. 1 and 11, the second end of the lock shaft 30 has an adjustment tapered surface 31, and the adjustment tapered surface 31 gradually decreases in a direction from the first end to the second end of the lock shaft 30. With the above structure, when the second end of the lock shaft 30 extends into the accommodating cavity 211, the adjusting tapered surface 31 of the second end of the lock shaft 30 can be matched with the matching portion 53, that is, the lock shaft 30 is attached to the arc-shaped notch 531 through the adjusting tapered surface 31. When the dimensions of the locking pin 10 change (due to machining errors or different dimensions, etc.), the depth of the adjusting cone 31 extending into the arc-shaped notch 531 will also change accordingly, so that the locking pin 10 can be clamped. This prevents the lock shaft 30 from being inserted into the arc-shaped notch 531 when the size of the lock pin 10 is changed, and thus, the locking effect is not achieved.
When the first LED housing 61 and the second LED housing 62 are to be connected, the lock pin 10 on the first LED housing 61 needs to be inserted into the accommodating cavity 211 of the lock base 20 on the second LED housing 62, the lock pin 10 is located between the first end of the first clamping member 51 and the first end of the second clamping member 52, and the lock shaft 30 is inserted into the accommodating cavity 211 to cooperate with the cooperating portion 53 of the first clamping member 51 and the cooperating portion 53 of the second clamping member 52, so that the first end of the first clamping member 51 and the first end of the second clamping member 52 are separated from each other, and the second end of the lock shaft 30 has the adjusting tapered surface 31, so that the handle 40 rotates to drive the lock shaft 30 to extend a distance, so that the claw portion 54 of the first clamping member 51 and the claw portion 54 of the second clamping member 52 approach each other. Here, the claw portion 54 of the first clamping member 51 and the claw portion 54 of the second clamping member 52 do not clamp the locking pin 10 completely, and the first LED housing 61 can be adjusted in a small range with respect to the second LED housing 62. When the adjustment is completed, the handle 40 is continuously rotated, and the adjustment conical surface 31 gradually decreases in the direction from the first end to the second end of the lock shaft 30, so that the second end of the lock shaft 30 continuously extends into the accommodating cavity 211, the claw portion 54 of the first clamping member 51 and the claw portion 54 of the second clamping member 52 continuously approach each other, so that the claw portion 54 of the first clamping member 51 and the claw portion 54 of the second clamping member 52 can apply force to the lock pin 10 to further achieve the clamping effect, and the connection structure of the connecting assembly 63 is ensured to be firm.

With the above structure, by arranging the arc groove 33 on the lock shaft 30, the arc groove 33 and the locking pin 212 can be matched, the locking pin 212 stretches into the arc groove 33, and when the lock shaft 30 rotates, the locking pin 212 does not rotate, and then the locking pin 212 can slide in the arc groove 33, so that the movement of the lock shaft 30 can be limited under the action of the locking pin 212.
As shown in fig. 1 and 11, the first end of the lock shaft 30 has a clamping boss 34, the inner sidewall of the handle 40 has a clamping groove matched with the clamping boss 34, and the handle 40 is fixed with the second end of the lock shaft 30 by a fastener. With the above structure, the clamping groove is formed in the handle body 41, and is matched with the clamping boss 34 at the first end of the lock shaft 30, so that the handle 40 and the lock shaft 30 are clamped with each other, the handle 40 and the lock shaft 30 can be rotated together, and in order to avoid the problem that the lock shaft 30 and the handle 40 are separated in the rotation process of the handle 40, the handle 40 and the lock shaft 30 are fixed through the fastener, and the separation of the lock shaft 30 and the handle 40 can be avoided. The fastener only plays a role of connecting the lock shaft 30 with the handle 40, and cannot ensure that the lock shaft 30 and the handle 40 can rotate together, so that the lock shaft 30 and the handle 40 can rotate together, and the problem that the handle 40 rotates relative to the lock shaft 30 is avoided because the clamping boss 34 is matched with the clamping groove.
