After the scaffold is assembled, a scaffold plate needs to be paved on the scaffold platform, and a worker can walk on the scaffold plate. For the connection mode of the scaffold boards, the simple method uses binding ropes to bind the connection positions, so that the scaffold boards and the transverse rod pieces are connected into a whole; special scaffold board connectors are also used as adapters to connect and secure scaffold boards.

But the fixing effect of binding and reinforcing by adopting the common binding ropes is uneven, the condition that the scaffold board is loose possibly occurs because the connection strength of the local position is not up to standard, and even accidental falling accidents can occur in serious cases. The scaffold board connecting piece on the market at present generally adopts a buckle connection or a bolt connection mode, the buckle connection structure needs to be locked through bolts, and the process of screwing the bolts consumes time; the bolt connection is simple and convenient to install, but the pin shaft needs to be independently stored after the bolt connection is disassembled, the loss is possible, and the inconvenience still exists.

It should be noted that the inner wall surface of the buckling groove 410 is curved and is attached to the cross bar 100, so as to enhance the combination stability of the two.

The clamping part 400 is further provided with a sliding fastener 500 which is slidably connected with the clamping part 400 and can extend out of the clamping part 400, so that the projection of the sliding fastener 500 along the horizontal direction can partially cover the opening, and after the cross rod 100 enters the opening, the cross rod 100 can be prevented from falling out of the buckling groove 410 by moving out the sliding fastener 500, thereby achieving a locking effect.

Further, the side of the slider 500, which can contact the cross bar 100, is a first side, which is curved and is attached to the cross bar 100, so as to increase the contact area with the cross bar 100, thereby improving the stability after installation.

The present application proposes a variety of possible embodiments for the specific arrangement of the clamping portion 400 and the slider 500. It should be noted that the present application is not limited to the embodiments described below.

First embodiment:

Referring to fig. 2, the sliding direction of the slider 500 is clockwise or counterclockwise about the crossbar 100, and the first side thereof remains in contact with the crossbar 100 as the slider 500 moves. The sliding fastener 500 is provided with a circular arc-shaped first guide groove 510, the clamping part 400 is provided with a circular arc-shaped first limiting block 420, and the first guide groove 510 is sleeved on the outer side of the first limiting block 420, so that the sliding fastener 500 is limited by the first limiting block 420 to slide along a specific direction. It should be noted that the centers of the first guide groove 510 and the first limiting block 420 are on the central axis of the cross bar 100, so that the slider 500 slides around the cross bar 100.

Second embodiment:

Referring to fig. 3, the sliding direction of the slider 500 is clockwise or counterclockwise about the crossbar 100, and the first side thereof remains in contact with the crossbar 100 as the slider 500 moves. The sliding fastener 500 is provided with a circular arc-shaped first guide groove 510, the clamping part 400 is provided with at least two second limiting blocks 430, and all the second limiting blocks 430 can be sleeved by the first guide groove 510, so that the sliding fastener 500 is limited by each second limiting block 430 to slide along a specific direction. It should be noted that the center of the first guide groove 510 is on the central axis of the cross bar 100, so that the slider 500 slides around the cross bar 100.

Third embodiment:

Referring to fig. 4 and 5, the third stopper 440 and the fourth stopper 450 are disposed on the locking portion 400, and correspondingly, the second guiding groove 520 and the third guiding groove 530 are disposed on the sliding fastener 500, the second guiding groove 520 is sleeved on the outer side of the third stopper 440, and the third guiding groove 530 is sleeved on the outer side of the fourth stopper 450. The second guide groove 520 is circular arc-shaped and has a center on the central axis of the cross bar 100. It is noted that the third guide groove 530 has a first end 531 and a second end 532 at two ends. When the sliding fastener 500 is fully opened to fully expose the opening, the fourth limiting block 450 is located at the first end 531 of the third guiding slot 530, and when the sliding fastener 500 is fully closed to partially cover the opening, the fourth limiting block 450 is located at the second end 532 of the third guiding slot 530. The first end 531 of the third guide channel 530 is farther from the rail 100 than the second end 532 of the third guide channel 530 is from the rail 100.

Further, the second end 532 of the third guide slot 530 is equidistant from the rail 100 as the second guide slot 520 is equidistant from the rail 100.

Further, an inflection point 533 is provided in the middle of the third guide groove 530, and a portion from the inflection point 533 to the second end 532 of the third guide groove 530 in the third guide groove 530 is a locking section 534, and the locking section 534 is circular arc-shaped and has a center on the central axis of the cross bar 100.

The beneficial effect of this design is that, when the sliding fastener 500 is completely opened, the fourth limiting block 450 is located at the first end 531 of the third guiding groove 530, and because the first end 531 is farther from the cross bar 100 than the second end 532, the upper end of the sliding fastener 500 moves toward the inside of the fastening groove 410, so that the sliding fastener 500 rotates around the third limiting block 440, the lower end of the sliding fastener 500 swings outwards, and the cross bar 100 is easier to enter the fastening groove 410.

When the slider 500 is closed, referring to fig. 6, the fourth stopper 450 moves from the first end 531 to the inflection point 533. At this time, the lower end of the sliding fastener 500 is retracted inward and attached to the side of the crossbar 100, and the sliding fastener 500 applies a lateral force to the crossbar 100, so that the crossbar 100 is mounted in place.

Referring to fig. 7, the fourth stopper 450 enters the locking section 534 of the third guide groove 530, and since the centers of the locking section 534 and the second guide groove 520 are on the central axis of the crossbar 100, the slider 500 slides around the crossbar 100 to further cover the opening, thereby completing locking and preventing the crossbar 100 from being removed from the latch groove 410.

The scaffold comprises the scaffold plate connecting device.
