Abstract
The utility model relates to the automatic door field, in particular to a folding door, which consists of a door frame, a door leaf, a transmission frame component, a rotary arm component, a transmission rod component and an orienting device; the side cheek of the side door leaf is articulated with the middle door leaf by a hinge, and upper ends and bottom end of another side door cheek of the side door leaf are respectively provided with a top and a bottom rotary shafts, and the rotary shaft is connected with the top and bottom rotary shaft bases of the two side door frames at the door hole; the top rotary shaft end is provided with the rotary arm component and the transmission component, while the transmission frame component and the door opener is arranged at the middle of the door frame top. When power switches on, the door opener runs and drives the two gears in the transmission frame to rotate, and the two racks meshed with the door opener move in a straight line; while another end of the rack is connected with the rotary arm which runs in a circle and drives the side door cheek rotating around one side cheek, and simultaneously drives the middle leaf rotate for 90 degree together, consequently, the door leaf opening and closing are achieved. A safety protection device is respectively positioned at the middle slots of the two middle door leaves, thereby promising returning to a completely open state in case of meeting a barrier when closing, ensuring security and reliability.
Description
Invention field: the utility model relates to the automatic door field, relates in particular to a kind of folding door.
Background technology: industrial premises, warehouses etc. need to install automatic door, as electronic sliding door, pan-up door etc., our company's number of patenting once is 95240516.4 electronic sliding door, the patent No. is 96243318.7 pan-up door, for example the patent No. is 96243318.7 pan-up door, its structure comprises a body, guide rail, control system, door lifter, traction component, transmission component and balance weight assembly, the guide wheel of door body both sides places guide rail, assembly pulley in the upper end fixed traction assembly of guide rail, steel cable in the traction component is walked around assembly pulley, one end connects the upper end of door body, the other end connects balance weight assembly, the sprocket of power transmission shaft one end is through chain and the engagement of door lifter upper sprocket wheel in the transmission component, the sprocket engagement of the sprocket of the power transmission shaft other end on chain and door body, the unlatching of this class automatic door drives the door body by door lifter and moves in track separately and realize, its weak point is that a body both sides or door body top need bigger space to hold the door leaf of unlatching, the restricted influence of service condition the application of above-mentioned automatic door.
Technology contents: technical problem to be solved in the utility model provides a kind of compact conformation, is not subjected to about door opening, the folding door of spatial constraints up and down.
Technical problem of the present utility model is achieved through the following technical solutions: a kind of folding door is made up of doorframe, door leaf, gear frame parts, pivoted arm parts, drive link parts and bearing unit, door leaf is totally four fans, side door fan, each two fan of middle door leaf, side door is fanned between limit stile on one side and the middle door leaf by hinge-coupled, side door fan another side stile upper and lower side is equipped with lower rotary shaft respectively, rotating shaft and door opening both sides doorframe shaft seat up and down link, last rotating shaft end is installed pivoted arm parts, drive disk assembly, and gear frame parts and door lifter are installed in the middle of the doorframe top; Middle door leaf is provided with bearing unit.When electronic, door lifter running back drives two gear rotations of gear frame inside, two tooth bar moving linearlies with its engagement, the other end of tooth bar connects with pivoted arm, pivoted arm is made circular motion, pivoted arm drives side door stile around the rotation of one side stile, door leaf half-twist together in driving simultaneously, thus realize the door leaf opening and closing.The middle close joint of door leaf all is equipped with safety guard in two, meets obstruction when closing and gets back to the full open state, and is safe and reliable.
The utility model compared with prior art has following advantage:
1. because automatic door adopts folding mode, so this automatic door is not subjected to about door opening, the restriction in space up and down: and this type not only can be installed on indoor but also can be installed on outdoor;
2. the middle close joint of door leaf all is equipped with safety guard in two, meets obstruction when closing and gets back to the full open state, and is safe and reliable;
3. in door lifter, be provided with manual clutch, when having a power failure, can spur rope and open clutch wheel and rack is separated, can realize the unlatching and the closure of door then by handle.
4. personnel's turnover for convenience also is provided with a wicket on middle door leaf.
5. between door leaf and doorframe, door leaf and door leaf, door leaf and ground, be equipped with seal, can have guaranteed the sealing effectiveness of whole door like this.
