Description
Technical field
The utility model relates to a kind of device that turns of electric door, especially relates to a kind of device that turns of flat opening electric door.
Background technology
Along with socioeconomic fast development, various types of electric door are widely used in factory building, retail shop, hotel, garage, dwelling house, villa etc., electric door of a great variety, its structure is looked different occasions and is different, but its operating principle is all identical, promptly all be the motion of giving door leaf by the transmission of power that transmission device produces motor, drive the opening and closing of door leaf by the forward or reverse of motor.At electric power just often, general equal can satisfy preferably use needs, but motor shuts down, owing to the motion and the motor of whole electric door is connected as a single entity, door leaf just can't be opened, thereby some electric door just are provided with the enforced opening structure.The flat opening electric door is owing to open conveniently, it is little to take up room, more and more be subjected to customer's welcome, the flat opening electric door turn device owing to consider to meet have a power failure or accident takes place must emergency power off the time, can manually opened door leaf, the transmission of general employing clutch friction, but because fricative torsion is limited, meet bigger wind-force or door leaf when too heavy, clutch easily skids, and makes the door leaf opening and closing not in place, particularly in coastal cities, regular typhoon, more be prone to the not tight situation in a pass, thus this city that is not suitable for often blowing by the electric door of clutch friction transmission, the coastal cities of particularly often blowing typhoon.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes above existence, and a kind of device that turns of flat opening electric door is provided, and this turns the influence that device is not subjected to wind-force size or door leaf weight, and meets when having a power failure or cutting off the power supply, can manually opened door leaf.
For realizing above purpose, electric door of the present utility model turns device and comprises motor, transmission mechanism and pivoted arm, and above-mentioned transmission mechanism is gear drive, is linked with axle sleeve on the gear-driven output shaft, first contiguous block radially is equipped with in the side of axle sleeve, and the first contiguous block end face is provided with groove; Described pivoted arm one end vertically is provided with chute, chute one end is provided with baffle plate, be provided with the spring and second contiguous block in the chute, spring one end is near baffle plate, the other end connects second contiguous block, and the second contiguous block other end is provided with projection, and this projection flexibly is embedded in the groove of first contiguous block, chute is provided with cover plate, and cover plate one end and gear-driven output shaft articulate.
The said gear transmission is the worm and gear transmission, and the rotating shaft of worm gear is described gear drive output shaft, and worm gear and worm screw are meshing, and the end of worm screw is connected with the output shaft of described motor.
Above-mentioned chute and baffle plate predetermined fixed are in the bottom surface of cover plate.
For second contiguous block is positioned in the chute, the other end both sides of above-mentioned chute are provided with limited block, this limited block also predetermined fixed in the bottom surface of described cover plate.
In order to regulate the adhesion of projection and groove, to be suitable for the needs of different wind-force, above-mentioned baffle plate both sides are provided with the device of an adjustable springs elastic force size.
In order to make projection be easy to skid off and slip into, the top of above-mentioned projection is taper, and groove is a splayed.
In order to reduce the frictional force between projection and the groove contact surface, the side of above-mentioned groove is that circular arc is excessive.
Electric door of the present utility model turns device, because transmission mechanism adopts this hard connection of gear drive, make this turn device does not influence door leaf because of the wind-force size the degree that closes, and rabbet by the elasticity between first contiguous block and second contiguous block between pivoted arm and the transmission mechanism, increased the structure of enforced opening, meet when having a power failure, use the hand propelled door leaf, when torsion reached certain limit, the projection of first contiguous block skidded off the groove of second contiguous block, and door leaf is opened, during power up, promote door leaf from opposite side, make the projection of first contiguous block slip into the groove of second contiguous block, electric door is normally moved.The set telescopic spring degree adjusting device in baffle plate both sides in addition, the size that can come regulating spring elastic force according to the size of different regions, Various Seasonal wind-force reaches the adhesion of control projection and groove.It is simple, easy to operate that electric door of the present utility model turns apparatus structure, and have the enforced opening structure, brings convenience for user's normal use.

Specific embodiment
As shown in Figure 1, 2, electric door of the present utility model turns device and is made up of motor 1, transmission mechanism 2 and pivoted arm 3 three parts.Transmission mechanism is made up of worm gear 21 and worm screw 22, the end of worm screw is fixed in the output that motor rotates, the part 221 of spiral is mutually meshing with the teeth of worm gear, the rotating shaft 211 of worm gear is linked with a cylinder-shaped sleeve 4, the lateral surface of axle sleeve radially is equipped with first contiguous block 41, contiguous block 41 end faces are provided with and are splay groove 411, and the side circular arc of groove is excessive; Pivoted arm is made up of with the junction plate 32 that is connected actuating arm and worm wheel shaft the actuating arm 31 that is installed on the electronic door leaf, junction plate is provided with cover plate 33, between junction plate and cover plate, be provided with chute 321, one end of chute is provided with baffle plate 322, other end both sides are provided with limited block 323, and for easy to process, this chute, baffle plate and limited block predetermined fixed are in the back side of cover plate, during installation, be screwed again on junction plate 32.Be provided with two springs 5 and second contiguous block 6 in the chute side by side, spring one end is fixed with a riser 51, and near baffle plate 322, and the other end withstands contiguous block 6, one screws 8 and passes baffle plate 322 and be connected with riser 51, and this screw is used for the dilatability of regulating spring; The other end of contiguous block 6 is provided with tapered protrusion 61, and this projection is stretched out chute and rabbeted with groove 411 elasticity, and the cover plate other end is to having pivot connector 331, and this pivot connector articulates by axle sleeve 4 and worm wheel shaft 211.In order to make the whole device compactness that turns, also for the ease of burying underground, transmission mechanism and motor are coated by a casing 7, as shown in Figure 5.
Electric power just often, the motor forward or reverse drives worm gear clockwise or rotate counterclockwise because first contiguous block and second contiguous block are halved together, shown in Fig. 3,5, the rotating shaft of worm gear drives pivoted arm by axle sleeve and comes back rotation, makes door leaf open or close.During power failure, motor stops operating, and enforces door leaf, and pivoted arm is lateral stressed, when torsion reaches certain limit, the projection of second contiguous block skids off the groove of first contiguous block, shown in Fig. 4,6, door leaf is opened, during power up, promote door leaf from opposite side, make the projection of second contiguous block slip into the groove of first contiguous block, electric door is normally moved.When wind-force is big, adjustment screw, the compression spring increases the elastic force that applies to projection, thereby increases the adhesion of projection and groove, and the door leaf opening and closing are put in place.
