Description

90 degree door lifters

Technical field

The utility model relates to the automatic door technical field, and is relevant with a kind of 90 degree door lifters especially.

Background technology

Traditional door opening ways a lot has varied, and 90 degree door-opening modes are a kind of structures commonly used, the development of state-of-the-art technology, and the development of automatic door field is rapid, and therefore 90 degree door lifters are design problems of a hot topic.

Existing 90 degree door lifters, complex structure, spare and accessory parts are many, and repair rate is high, causes cost to reduce.Therefore the inventor has conscientiously done research, designs a kind of 90 degree door lifters, and this case produces thus.

The utility model content

Main purpose of the present utility model provides a kind of 90 degree door lifters, and is simple in structure, dynamical stability.

In order to achieve the above object, the utility model is achieved through the following technical solutions:

90 degree door lifters comprise motor, motor reduction gearbox, the bar that opens the door, track strip; Motor-driven connects motor reduction gearbox, and both are fixed on the doorframe, and the reducer output shaft of motor reduction gearbox connects an end of the bar that opens the door, and the other end of the bar that opens the door is equipped with the roller that can slide in track strip, and track strip is fixed on the door leaf.

Described motor, motor reduction gearbox are installed in the housing, and whole housing is fixedly mounted with the upper edge with doorframe.

Transformer, cowling panel also are housed in the described housing; External power source carries out rectification by transformer, cowling panel successively, is the control panel power supply of control machine operation.

Reserve battery also is housed in the described housing.

Described motor reduction gearbox comprises reduction box casing, is supported with secondary driving shaft, three grades of driving shafts, reducer output shaft by bearing on the reduction box casing; The output shaft of motor by be installed on the secondary driving shaft worm gear with transmission of power in motor reduction gearbox, secondary driving shaft and three grades of driving shaft gear engaged transmission, three grades of driving shafts and reducer output shaft meshed transmission gear.

After adopting such scheme, motor provides power to motor reduction gearbox in the utility model, slow down by the motor reduction gearbox transmission, final outputting power from the reducer output shaft, when the reducer output shaft rotational angle, the drive bar rotational angle that opens the door realizes that 90 degree open the door so that the bar that opens the door is stirred door leaf.Whole door lifter compact conformation, good looking appearance, power provide stable, long service life, repair rate is low, effectively reduces cost.

The specific embodiment

By reference to the accompanying drawings, preferred embodiment is described in further details to the utility model.

90 degree door lifters, the parts that are mainly concerned with comprise motor 1, motor reduction gearbox 2, left end cap 3, drain pan 4, right end cap 5, reserve battery 6, cowling panel 7, transformer 8, the bar 9 that opens the door, track strip 10.

In the both sides of drain pan 4 left end cap 3 and right end cap 5 are housed respectively, form an all-in-one-piece housing, motor 1, motor reduction gearbox 2, reserve battery 6, cowling panel 7, transformer 8 all are installed in the housing.When mounted, whole housing is fixed on the upper edge of doorframe 20.

Motor reduction gearbox 2 comprises reduction box casing 11 shown in Fig. 3 to 5, be supported with secondary driving shaft 13, three grades of driving shafts 14, reducer output shaft 15 by bearing 12 on the reduction box casing 11.

Motor 1 is installed in the outside of reduction box casing 11, at secondary driving shaft 13 worm gear 16 is installed, and motor 1 arrives transmission of power in the motor reduction gearbox 2 by worm gear 16, drives secondary driving shaft 13 and rotates.Secondary driving shaft 13 and three grades of driving shaft 14 meshed transmission gear, three grades of driving shafts 14 and reducer output shaft 15 meshed transmission gear.One end of reducer output shaft 15 stretches out outside the reduction box casing 11, thus, and transmission of power and going out the most at last.When housing was fixed on the upper edge of doorframe 20, reducer output shaft 15 was to lay down.

The bar 9 that opens the door is a kind of rod members, and the one end is connected with reducer output shaft 15, and a roller 17 is housed on the other end.The size and shape of roller 17 is fit to be assemblied in the track strip 10 and slides.Track strip 10 is fixed on the top of door leaf 21, by the bar 9 that opens the door motor reduction gearbox 2 is connected connection with track strip like this.

Such as Fig. 6, Fig. 7, when motor 1 starts, with power transmission to motor reduction gearbox 2, motor reduction gearbox 2 power are finally from reducer output shaft 15 outputs, then drive the bar 9 that opens the door and rotate, the other end of the bar 9 that opens the door is in track strip 10 interior slips, and 90 degree that finally drive whole door leaf 21 are opened.

In the utility model, the unlatching of motor 1 is by the control of control panel (not shown), and external power source forms power supply by cowling panel 7 and transformer 8, powers to control panel.For so that outage guarantees that door lifter normally uses, in housing, dispose simultaneously reserve battery 6 and power to control panel.

Above-described embodiment only is used for explaining inventive concept of the present utility model, but not to the restriction of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
