Therefore, the utility model is suitable for the situations assembling the automatic doors, such as factory and storehouse.

Description

The turnover lever gear door

Invention field: the utility model relates to the automatic door field, relates in particular to a kind of turnover lever gear 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: the purpose of this utility model provides and a kind ofly promotes safe and reliable, compact conformation, is not subjected to about door opening, the turnover lever gear door of spatial constraints up and down.

The purpose of this utility model is achieved through the following technical solutions, a kind of turnover promotes, by door leaf, guide rail, control system, balance sysmte, stopping means and motor constitute, it is characterized in that: door leaf is hinged by some door-plates, the guide wheel that each piece door-plate both sides is provided with places guide rail, guide rail top is bowing for one section, the motor of door leaf top is connected with the reductor rotating shaft of a side separately by the drive link of both sides, sprocket wheel on the speed reducer output shaft is connected with the catch pawl device that is arranged on the door leaf both sides through chain, the tooth bar that cooperates with catch pawl is fixed in the column of door leaf both sides, in the door opening of nearly bottom, door leaf both sides the infrared electro device is set, a side reductor is provided with manual clutch; The gears engaged that is provided with on gear that screw mandrel one end is fixed in the stopping means and the speed reducer output shaft; Stopping means is by the fixing gear of the screw mandrel in case, the case, screw mandrel one end, is screwed in the travel switch that collision block on the screw mandrel and collision block two ends are fixed on the case and constitutes; The utility model door leaf adopts the polylith door-plate hinged, both can be along the craspedodrome orbital motion, the orbital motion that also can have radian along the upper end, save door opening upside space, the catch pawl device is set when chain gets loose, struts catch pawl through spring action, firmly be stuck in door leaf on the stationary rack, the infrared electro device that is provided with can be in door body decline process pass through to block motor power circuit because of the human or animal, guarantee being perfectly safe of door leaf operation, safe and reliable, the compact conformation of the utility model is applicable to that factory building, warehouse etc. install the place of automatic doors.
