Abstract

The invention relates to a side-hung door machine of swing arm type, which comprises a swing arm, a connector fixed on the door body and a fixing piece fixed on the fixed object at one side of the doorframe. The invention is characterized in that: the connector is connected with on end of the swing arm dynamically; and the other end of the swing arm is provided with a motor and a speed reducer; the output shaft of the speed reducer and the guide shaft are respectively fixed with umbrella shaped gears which are meshed with each other; a matching piece integrated with the guide shaft is provided with retractable convex keys in a radical direction; the matching piece is sheathed on the fixing piece; key grooves are arranged at the place on the fixing piece and corresponding to the convex key; the opening/closing of the door can be drew or pushed by utilizing the motor to drive swing arm to swing. Except that the positions of the door-body rotating shaft and the guide shaft of the positioning swing arm are fixed, the side-hung door mechanism of the invention is characterized in that: the swing arm and the door body are connected dynamically; the point of strength can change dynamically with the variation of the opening angle of the door, leading to being forced directly, and the swing arm can be arranged close to the door body; therefore the whole structure is more compact and beautiful; moreover, the door body can basically achieve closing/opening in constant speed with a large opening angle.

Description

Oscillating arm type horizontal opening door machine

Technical field:

The invention belongs to mechanical field, particularly a kind of oscillating arm type horizontal opening door machine that can automatically controlled automatic open and close.

Background technology:

Existing automatic door lifter at vertical hinged door roughly is divided into two classes, one be mounted in a body bottom can be independently at the door lifter of ground running; Two are mounted in a stroke formula door lifter of body back driving gate body automatic open and close.Need the land arc operation of the driving wheel of the former door lifter is subjected to the influence of ground flat degree bigger, and cable is laid needs excavation ground, and engineering quantity is bigger, gives installing construction additional and make troubles.Latter's simple installation, but the angle of opening the door is restricted, and can only extreme angles be 90 degree, the obviously need in incompatibility market generally.Stroke formula door lifter adopts hydraulic-driven or screw drive mostly at present, its agent structure comprises-stroke bar, stroke bar moved end become dynamically hinged with connector on being fixed on a body, the other end is positioned on the axle point of fixture such as doorframe, this mechanism is by forming a variable triangle between stroke bar, axle dotted or gate axon point, door axon point and connector, and the telescopic variation of stroke bar moved end can realize the keying of a body.

Summary of the invention:

The objective of the invention is to design a kind of oscillating arm type horizontal opening door machine that utilizes power swing arm driving gate body to open and close.

Technical solution of the present invention is achieved in that a kind of oscillating arm type horizontal opening door machine, comprise swing arm, be fixed on the connector on the body and be fixed on fixture on the doorframe one side fixture, it is characterized in that connector becomes dynamically to be connected with an end of swing arm, the swing arm other end is equipped with motor and reducer, reducer output shaft and guide shaft are fixed with intermeshing bevel gear respectively, with radially be provided with telescopic protruding key on the counterpart of guide shaft disjunctor, counterpart is sheathed on the fixture, and the corresponding protruding key of fixture place is provided with keyway.Utilize motor-driven swing arm swing and the keying of traction or promotion door body, the motor-driven bevel gear rotates, because the gear that is fixed on guide shaft one side is motionless, makes the gear rotation of bevel gear on guide shaft on the reducer output shaft, and make the swing arm that motor and reducer are installed produce swing.This structure is except the guide shaft fixed-site of rotating shaft of door body and location swing arm, swing arm is adopted with the door body and dynamically is connected, its origin of force produces dynamic change along with the difference of door body opening angle, and does not have stroke spacing and angle variation, installs so swing arm can be close on the body.

The present invention has reasonable in design, utilizes the swing arm traction or promote the door body to open and close, and is stressed direct, no angle considers that swing arm can nestle up a body and install between swing arm and door body, and integral body is compact more attractive in appearance, and Men Tike reaches constant speed substantially and opens and closes, and opening angle is big.

The specific embodiment:

Embodiment one:

See figures.1.and.2, a kind of oscillating arm type horizontal opening door machine, comprise swing arm 1, be fixed on the connector 2 on the body and be fixed on fixture 3 on the doorframe one side fixture.Swing arm 1 is telescopic swing arm in this example, is also promptly formed by swing arm 1 and sleeve pipe 11 intussusceptions, and connector 2 one ends that are fixed on the body directly are connected with sleeve pipe 11 1 ends by hinge 4, the dynamic connection of formation on the end of swing arm 1 that is slidingly located in of sleeve pipe 11 other ends.Tube shaped electric machine 5 and reducer 51 are installed in the swing arm 1, swing arm 1 can be selected seamless tubular goods for use, reducer 51 is selected planetary gear speed reducing mechanism for use, both satisfied speed reducing ratio, has cylindrical outer shape again, can better be contained in the swing arm 1, reducer output shaft and guide shaft 6 are fixed with intermeshing bevel gear 7 respectively, radially be provided with telescopic protruding key 62 with the counterpart 61 of guide shaft 6 disjunctors, corresponding protruding key 62 places are provided with keyway 31 on the fixture 3, and protruding key 62 falls into keyway 31, and guide shaft 6 is lockable, motor 5 rotations can drive swing arm 1 around guide shaft 6 swings, and traction or promotion door body open and close.In addition, reducer 51 output shafts are related by an angle bar 71 with 6 of guide shafts, guarantee that gear has reliable engagement for 7 groups.

Telescopic protruding key 62 is by lock core control in this example, and lock core is installed on the axis of counterpart 61, and opening perhaps is installed in lock core the side direction of counterpart down.Because the relation of speed reducing ratio, reducer has self-locking action, in case when having a power failure, the protruding key 62 that needs to stretch breaks away from the restriction of keyways 31, so that manpower driving gate body opens and closes, the configuration lock core is promptly safer.Certainly telescopic protruding key 62 also can adopt common feather key, directly pulls out the releasing locked state.

Embodiment two:

With reference to Fig. 3 and Fig. 4, basic structure and last example are that connector 2 is connected with the chute-type that dynamically is connected to of an end of swing arm 1 together.The connector 2 that is fixed on the body is meant that with 1 dynamic connection of swing arm swing arm 1 downside offers chute 12, and connector 2 turns bent end and can insert in the chute 12, forms dynamically to connect.In order to reduce slip resistance, connector 2 turns bent end and is arranged with pulley 21, and the diameter of pulley 21 is slightly less than chute 12 groove widths, and chute 12 left groove sides are touched mutually with pulley 21 when opening the door, and traction door body is opened; And at closing time, the right groove side of chute 12 is touched mutually with pulley 21, promotes the door body and closes.The switching motion of door body, pulley 21 can be alternately about roll on the two groove sides, can effectively reduce the resistance of mechanism's operation; Certainly also can turn bent end at connector and be arranged with slide block, the slide block width is slightly less than the chute groove width, adds some lubrication oil between the two, and slide block can slide freely in chute.

In above-mentioned two examples,, also can make structure, under the state that has a power failure, open and close operation but manpower directly promotes a body, and need not to remove the lock-out state of protruding key like this, offer convenience to use with self-locking by selecting suitable speed reducing ratio for use.
