Description
Technical field
The wood invention relates to the limiter of rotary opening closing door usefulness, a kind of door limitation device of vertically exerting resisting force particularly, this door limitation device is arranged in the lower edge and the gap between the ground of door, to the lower edge of door vertically exerting resisting force, make and utilize the door that rotates and do to open and close to remain on required door opening state.
Background technology
In high-rise residential building, office premises, every floor face leads to upper and lower stair place all installs revolving door, and also revolving doors of separating usefulness that are equipped with add automatic door closer for these doors can be closed automatically usually in every layer the public passage, as spring door closer etc., brought convenience to people.
But stair passage, flooring public passage are done cleaning every day, are regularly opened gate open wind and people when removing west, the Far East, need the long period to open these revolving doors, and the existence of automatic door closer is also made troubles to work.At present, do cleaning, regularly open gate open wind or remove Far East when west, usually block to stop and close automatically by the special messenger or with the article that constant weight is arranged.
What have is pressed into a wedge-like position limiter for door between the lower edge of ground and door, or call at any time a cushion block stop the door close, since the spring automatic door closer to close a moment big, impact force is big, and the lower edge of revolving door and wedge-like position limiter for door or cushion block are again for line contacts, and the pressure of opposite house is bigger, use or use for a long time them to stop door to be closed repeatedly, will inevitably cause the distortion at student edge, destroy the outward appearance of door, the application life of influence door.
Summary of the invention
The objective of the invention is to overcome the above-mentioned defective that prior art exists, a kind of door limitation device of vertically exerting resisting force is provided, uses with the lower edge and the big occasion of the gap size between the ground that adapt to the door that automatic door closer is installed, bigger door and door.
The door limitation device of vertically exerting resisting force of the present invention is to realize like this.It comprises:
A rectangular susceptor, this rectangular susceptor has the bottom surface, and four limits of bottom surface extend upward the side, and interior is containing cavity;
A liftable upper casing, it is made up of rectangle frame and the cover plate that is fixed on above the rectangle frame, and the side inner surface stationary rack of rectangle frame has elongated slot on the rectangle frame of this tooth bar one side, and liftable upper casing spiral-lock is in the containing cavity of rectangular susceptor;
At least one support spring, it press-fits between rectangular susceptor that fastens and liftable upper casing; And,
A gear shaft, it passes the axis hole of rectangular susceptor side, the elongated slot of rectangle frame is connected with rectangular susceptor, the tooth bar engagement of gear on the gear shaft and rectangle frame inboard; This door limitation device tightly is placed between the lower edge of ground and door in the gap, stops door to be closed to the lower edge of door vertically exerting resisting force.
Wherein, the gear shaft outer end is provided with hexagonal hole or cubic hole, is used to cooperate throw to make the upper casing lifting.
The lid surface of liftable upper casing vertically can be provided with the convex-concave striped.The bottom surface of rectangular susceptor vertically can be provided with the convex-concave striped.
Do when cleaning or regularly opening gate open wind or remove west, the Far East, door limitation device tightly being placed between the lower edge of ground and door and stoping in the gap door to be closed, vertically apply resistance to the lower edge of door by spring-supported upper casing, is that face contacts with the lower edge of door, stressed even, avoided the distortion on student edge; Simultaneously, door limitation device is between the lower edge of ground and door in the gap, can not cause any obstruction to people current.
The door limitation device of this vertically exerting resisting force is novel, compact conformation, cost is low, installation, easy to use, can make the door that utilize to rotate and do to open and close remain on required door opening state, be specially adapted to add door, the bigger door of automatic door closer and require the student along and the bigger door use of ground clearance.
