Abstract
The utility model relates to a displacement controlling device, in particular to a reversible rotation limitation displacement controller, and contains the following structure: a bumper is positioned on a bumper base through bumper nuts, bolts, inching gears and a pallet and the inching gear and the inner ring of bumper base engage together. The utility model has the advantages that the bumper returning rotation in place makes the object turn back in place after a displacement and the structure of the utility model is reliable. The utility model can be applied widely in the displacement limitation controlling in garage door, industrial door and rolling shutter door and otherwise.
Description
Technical field
The utility model relates to a kind of travel control device, particularly a kind of reversible rotary stopper travel control device.
Background technology
At present, existing stroke limit control device, though long as the spacing precise control of tongue tube, life-span, be subject to electromagnetic interference (EMI); Existing mechanical is spacing can be occurred owing to cross move behind the stroke irreversible, the problem that causes spacing control fails and spacing parts to damage.
Summary of the invention
In view of above problem, the purpose of this utility model is: provide a kind of stroke limit control device, particularly a kind of reversible rotary stopper travel control device.
For achieving the above object, the utility model is by the following technical solutions: two collision blocks are fixed on the collision block frame by collision block nut, screw, fine setting gear and supporting plate respectively, fine setting gear and the engagement of collision block frame inner ring, adopt the rotation of collision block frame original position, return is reversible, and regulate the collision block present position by the fine setting gear, reach effective more spacing control and cross the stroke return.
Advantage of the present utility model is that the original position revolution of collision block makes after the process can return, and reliable in structure, can be widely used in the stroke limit control of various doors such as garage door, industrial door, rolling screen door.
Description of drawings
As shown in Figure 1, be structural representation of the present utility model;
As shown in Figure 2, be vertical view of the present utility model.
Embodiment
As shown in drawings, the utility model mainly comprises: collision block frame (1), collision block frame (2), collision block (3), collision block (4), collision block nut (5), fine setting gear (6), cross pan head screw (7), supporting plate (8).
As shown in the figure, collision block (3), collision block (4) are fixed on collision block frame (1) and the collision block frame (2) by collision block nut (5), cross pan head screw (7), fine setting gear (6) and supporting plate (8), fine setting gear (6) and the engagement of collision block frame (2) inner ring, can adjust the collision block present position by regulating fine setting gear (6), change the control stroke.
(a) when energising work, driven by power by the rotation of collision block frame (1) and collision block frame (2), drives collision block and moves as circumference, and when the door body rose to apical position, collision block (3) contacted microswitch, stopped a body motion.When the door body dropped to bottom position, collision block (4) commentaries on classics contacted microswitch, stopped a body motion.
(b) when power failure is manual, pull the chain hoisting gear and drive the motor rotation, transmission subsequently is with (a), but, behind collision block (3) and collision block (4) shake-up microswitch, because of no electric signal sends, collision block will continue to surmount microswitch along circular motion, cause stroke.Because collision block moves as circumference, radius of action is constant, so can not damage spacing parts, as long as oppositely continue aforesaid operations, collision block can be returned to original position again.
Claims (1)
1, a kind of rotary stopper travel control device, it is characterized in that: collision block (3), collision block (4) are fixed on collision block frame (1), the collision block frame (2) by collision block nut (5), screw (7), fine setting gear (6) and supporting plate (8), fine setting gear (6) and the engagement of collision block frame (2) inner ring.
