Example (b):

the roll up curtain door leaf that antiskid moves, as shown in fig. 1, including door leaf 1 and divide big connection bayonet 2 and the little connection bayonet 3 of locating door leaf 1 both ends, big connection bayonet 2 and little connection bayonet 3 terminal surface are C shape, as shown in fig. 4, the little connection bayonet 3 of single door leaf 1 is used for sliding and wears to locate in the big connection bayonet 2 of another door leaf 1, and can not deviate from 2 openings part of big connection bayonet to make two door leaves 1 connect.

In order to prevent the two door sheets 1 connected in place from sliding, as shown in fig. 2 and 3, a retractable limiting sliding ball 4 is vertically arranged in the middle of the outer surface of the small connecting bayonet 3 in the length direction, and an arc-shaped limiting sliding groove 5 is arranged in the middle of the inner surface of the large connecting bayonet 2 in the length direction. The opening of the arc-shaped limiting sliding groove 5 is larger than the diameter of the limiting sliding ball 4, and the longest distance from the center of the limiting sliding ball 4 to the opening of the small connecting bayonet 3 is not smaller than the distance from the opening of the arc-shaped limiting sliding groove 5 to the opening of the large connecting bayonet 2. The design makes as shown in fig. 4 and fig. 5, when two sheets of door 1 slide and wear the sleeve, the limited sliding ball 4 of one sheet of door 1 can be forced to contract and move towards its small connecting bayonet 3, make this small connecting bayonet 3 can slide and wear to locate in the big connecting bayonet 2 of another sheet of door 1, when the aforesaid limited sliding ball 4 moves to the limited sliding slot 5 department of 2 big connecting bayonet arcs of another sheet of door 1, this limited sliding ball 4 can stretch towards this limited sliding slot 5 of arc again, get into in this limited sliding slot 5 of arc, can slide in this limited sliding slot 5 of arc, thereby make the small connecting bayonet 3 that this limited sliding ball 4 connects restricted and can not slide, in order to spacing two sheets of door 1 on the direction of sliding, two sheets of door 1 can rotate relatively simultaneously.

Optionally, the limiting sliding ball 4 is vertically connected with the outer surface of the small connecting bayonet 3 through a spring 6 so as to realize the extension and contraction of the limiting sliding ball 4. Further, in order to avoid the torsion of the spring 6, a certain degree of slippage still exists after the two door sheets 1 are connected in place, as shown in fig. 6, a telescopic sleeve 7 is sleeved outside the spring 6, the telescopic sleeve 7 is connected between the limiting sliding ball 4 and the small connecting bayonet 3, and the telescopic sleeve 7 stretches along with the spring 6.

Preferably, the stopper slider 4 is not provided at an upper portion of the outer surface of the small bayonet 3 in the circumferential direction in order to make the rotation amount between the small bayonet 3 and the large bayonet 2 of the other blade 1 as large as possible.

Further, as shown in fig. 4, the limiting sliding ball 4 is disposed in the middle of the outer surface of the small connecting bayonet 3 in the circumferential direction, and the arc-shaped limiting sliding groove 5 penetrates through the inner surface and the outer surface of the large connecting bayonet 2. Above-mentioned design makes when dismantling lamella 1, can press the spacing sliding ball 4 of top lamella 1 through its arc spacing spout 5 from 2 surfaces of big connection bayonet sockets of below lamella 1, makes it break away from the arc spacing spout 5 of below lamella 1, slides top lamella 1 simultaneously to dismantle two lamella 1.

The utility model discloses a set up spacing ball 4 at 3 surface middle parts of little connection bayonet socket, 2 internal surface middle parts of big connection bayonet socket set up the spacing spout 5 of arc for big connection bayonet socket 2 of a lamella 1 and the little connection bayonet socket 3 of another lamella 1 can align automatically when sliding and wearing the cover, and obtain spacing no longer sliding. The door sheet 1 is connected, aligned and limited through the penetrating sleeves of the large connecting bayonet and the small connecting bayonet, a limiting accessory is not required to be installed, and the door sheet 1 is simple and convenient to assemble.

Parts not described in the above modes can be realized by adopting or referring to the prior art.
