Description

Collapsible vertical lift automatic door

The utility model relates to a kind of door.

Along with the continuous development of national economy and the raising day by day of living standards of the people, the ascending/decending metal door is widely used in places such as garage, warehouse, factory building, shop, and it is convenient that this type of door is not only opened, and intensity is good, also has anti-theft feature, so be subjected to customer's welcome deeply.At present, roller shutter type, convertible two kinds of automatic overhead doors have been arranged, but they are because self restriction also exists many shortcomings, and for example: the intensity of rolling curtain type door is relatively poor relatively, and harder during opening and closing, and electric rolling door then noise is bigger; Convertible door is better slightly than rolling curtain type door, but its guide rail is long, but also will take the upper space in house.

The purpose of this utility model is: a kind of collapsible vertical lift automatic door is provided, and it has, and intensity is good, noise is low, stable drive, advantage such as little, easy to use takes up room.

The technical solution of the utility model is: a kind of collapsible vertical lift automatic door, comprise doorframe, the centre of described upper door frame is provided with motor, motor is by the horizontal power transmission shaft of both sides, bevel gear drives the screw mandrel that vertically is located on left-hand door frame and the right doorframe, described screw mandrel is sandwiched in the guide rail, guide rail is separately fixed on left-hand door frame and the right doorframe, there is opening in the front of guide rail and is combined with the clasp nut piece, be provided with some door-plates in the described doorframe, be laterally hinged with mutually between the door-plate, and the both sides, the top of door-plate are hingedly fixed on left-hand door frame and the right doorframe by door-hinge, and the both sides bottom of door-plate are hingedly fixed on the clasp nut piece by door-hinge.

The further technical scheme of the utility model is: a kind of collapsible vertical lift automatic door, comprise doorframe, the centre of described upper door frame is provided with motor, motor is by the horizontal power transmission shaft of both sides, bevel gear drives the screw mandrel that vertically is located on left-hand door frame and the right doorframe, described screw mandrel is sandwiched in the guide rail, guide rail is separately fixed on left-hand door frame and the right doorframe, there is opening in the front of guide rail and is combined with the clasp nut piece, be provided with some door-plates in the described doorframe, be laterally hinged with mutually between the door-plate, and the both sides, the top of door-plate are hingedly fixed on left-hand door frame and the right doorframe by door-hinge, and the both sides bottom of door-plate are hingedly fixed on the clasp nut piece by door-hinge; The articulated position of described lastblock door-plate and next piece door-plate is in the inboard, lower end, and the articulated position of second door-plate and next piece door-plate is analogized with this at interval in the outside, lower end.

The more perfect technical scheme of the utility model is: a kind of collapsible vertical lift automatic door, comprise doorframe, the centre of described upper door frame is provided with motor, motor is by the horizontal power transmission shaft of both sides, bevel gear drives the screw mandrel that vertically is located on left-hand door frame and the right doorframe, described screw mandrel is sandwiched in the guide rail, guide rail is separately fixed on left-hand door frame and the right doorframe, there is opening in the front of guide rail and is combined with the clasp nut piece, be provided with some door-plates in the described doorframe, be laterally hinged with mutually between the door-plate, and the both sides, the top of door-plate are hingedly fixed on left-hand door frame and the right doorframe by door-hinge, and the both sides bottom of door-plate are hingedly fixed on the clasp nut piece by door-hinge; The articulated position of described lastblock door-plate and next piece door-plate is in the inboard, lower end, and the articulated position of second door-plate and next piece door-plate is analogized with this at interval in the outside, lower end; The two sides of described every door-plate are equipped with two door-hinges, and the termination of door-hinge is provided with guide wheel, and guide wheel is pressed on the guide wheel rail of being located at the guide rail outside.

During use, but by clockwise and anticlockwise motor as power, drive the screw mandrel rotation by power transmission shaft, bevel gear, make clasp nut do ascending motion, drive next piece door-plate when the clasp nut piece rises and rise foldingly, finish the action of opening the door; When motor reversed, the clasp nut piece was done descending motion, stretched thereby door-plate transferred, and finished the action of closing the door.

The utility model has the advantages that:

1. the utility model is the bellow framed door plated construction, makes vertical displacement movement, and not only intensity height, strong security, theftproof are good, and it is also little to take up room.

2. the utility model adopts the transmission of feed screw nut's structure, operate steadily reliable, noise is low.

3. collapsible door-plate of the present utility model can adopt different combinations according to user's doorframe size, and compliance is strong, and is convenient to transportation, installation and maintenance.
