The clamp plate 5 has two, and two clamp plate 5 length are the same with the long limit length of lock seat 1, and the centre is installed triangle iron 2. The triangular iron 2 and the clamping plate 5 are hinged through a hinge shaft 4, and the triangular iron 2 can rotate around the hinge shaft 4. That is, the width of the lock seat 1 is slightly larger than the total thickness of the two clamping plates 5 and the triangular iron 2, so that a gap is formed between the triangular iron 2 and the two clamping plates 5, and smooth rotation is ensured. Constitute the open slot that lock axle 3 removed between splint 5 and the lock seat 1, that is to say the open slot width is greater than the diameter of lock axle 3 to lock axle 3 can freely pass in and out the open slot, 3 one end of lock axle is fixed on the dodge gate, articulated shaft 4 is parallel with lock axle 3.

During installation, the lock seat 1 can be fixedly installed on a wall surface, a railing and other fixed equipment facilities, and the moving direction of the lock shaft 3 corresponds to the length direction of the opening groove during door closing during installation. I.e. the door panel translates left and right in fig. 1, i.e. parallel to the plane of the paper. When the door is in the open mode, triangle iron 2 rotates the extreme lower position, and its lower extreme falls on the long limit of lock seat 1 is interior along, and the hypotenuse is outside the open slot, and vertical limit is in the open slot, and the upper end exposes on two splint 5, triangle iron 2 can only use the hinge point to rotate as the center on lock seat 1 upper portion, and the rotation of lock seat 1 lower part is blockked by the long limit of lock seat 1 interior edge. When the door is closed, the lock shaft 3 enters the inside of the open slot and contacts with the inner edge of the short edge of the lock base 1, and the triangular iron 2 rotates anticlockwise as shown in figure 1 until the lock shaft 3 is separated from the triangular iron 2 and moves to the rightmost end of the figure.
