Fixed pin.The setting of arm plate is so that protruding shaft and cabinet effectively avoid limit plate and cabinet friction, structure is more with certain gap
Adduction reason is reliable.
Further, the fixed plate and bent plate, which pass through, is welded and fixed.
The utility model has the advantages that the door limiting device of the utility model, when rotating opening door-plate, door-plate drives limit plate around fixation
Screw rotation, along guiding elongated slot, holding tank slides protruding shaft to the right, after protruding shaft slides into right holding tank, continues to rotate opening door
Plate, protruding shaft are caught in left holding tank through retention bead, and left holding tank and retention bead limit protruding shaft, and door-plate, which is limited, to be protected
Opening state is held, because of the position-limiting action of retention bead, door-plate will not close suddenly；When being closed door-plate, manual toggle is needed to limit
Plate makes the left holding tank of protruding shaft disengaging slide into right holding tank through retention bead, and retention bead is again along the sliding of guiding elongated slot until door-plate is complete
Complete closure, position limiting structure is simple and reliable, and it is convenient to operate, and because of the position-limiting action of retention bead, door-plate will not close suddenly, and door-plate is beaten
There is locking function when opening, it is fool proof；The limit device structure is simply ingenious, is easily worked manufacture, install convenient, cost
It is low.
