Abstract

The utility model relates to an automatically opening and closing door, which is composed of a fixed door pivot, a door panel, a door frame and an autorotation mechanism. The autorotation mechanism is that a shifting shaft on the door panel is matched with a shifting rotary wheel of the door frame; the door panel utilizes the height adjustment of the gravity of the door panel to achieve the goal of automatic opening and closing performance through tilting a rotating shaft line of the door panel. The utility model is suitable for various buildings with doors and various objects provided with doors.

Description

Automatic door

The utility model relates to a kind of door that can open closure automatically.

In the prior art, automatic or semi-automatic door on building and all kinds of object that holds thing utilizes spring, photoelectricity, infrared rays or computer control more, and certain shortcoming is respectively arranged: utilize spring controlled door to open and close poor performance, push open difficultly, the pass is closed swift and violent and swing is arranged, and easily hurts sb.'s feelings; The required extra accessory cost height of door of photoelectricity, infrared rays or computer control is subjected to external interference more.

The purpose of this utility model provides a kind ofly to be utilized deadweight and opens the door that closes automatically.

The utility model is made up of fixed rotating shaft 1, door-plate 2, doorframe 3 and free-wheeling system, the displacement axle 4 that free-wheeling system promptly is fixed on another rotating shaft place on the door-plate 2 cooperates with the axis hole 7 of displacement runner 5 in being arranged on doorframe 3 and forms, the central axis of displacement axle 4 and the center axis deviation certain angle α of fixed rotating shaft 1, and displacement runner 5 can be suitable in doorframe 3, be rotated counterclockwise certain angle β, and drive displacement axle 4.

The utility model can adopt multi-form control member according to use occasion, as pedal, knob, button, pull bar etc., controls displacement runner 5, closes function to handle free-wheeling system, door-plate 2 is had to open automatically.

The utility model is when utilizing the object center of gravity to rise, gravitation will make its center of gravity produce downward trend, to reach the physical principle of stable state, door-plate utilization deadweight is reached open the purpose of closing automatically, simple and reasonable, performance is excellent, is easy to energy conservation is installed, cost is low, and be not subjected to the interference of external factor, long service life is applicable to various buildings and all kinds of object of installing door.

Describe in detail below in conjunction with accompanying drawing:

Fig. 1 installs the structural representation of displacement axle and displacement runner for the utility model,

Fig. 2 is the cooperation vertical view of displacement axle of the present utility model and displacement runner,

Among the figure, 1 fixed rotating shaft, 2 door-plates, 3 doorframes, 4 displacement axles, 5 displacement runners, 7 axis holes.

Embodiment 1: the last rotating shaft of establishing door is a fixed rotating shaft 1, free-wheeling system is formed by displacement axle 4 that is fixed on door-plate 2 bottoms and axis hole 7 cooperations that are arranged on the displacement runner 5 in the doorframe 3, the central axis of displacement axle 4 and the center axis deviation certain angle α of fixed rotating shaft 1, facts have proved that α is relevant with door-plate 2 deadweights and rotation friction, generally speaking, α is that 1～6 degree gets final product, and the actual rotation axis of door-plate 2 and vertical direction are deflection α angle.When the plane parallel of its yawing moment and door-plate 2, door-plate 2 left changes arbitrarily angled, and its center of gravity will be raise, gravitational effect, and door-plate 2 will be turned back to stable state automatically, therefore realize closing automatically the purpose of closing; And the yawing moment of actual rotation axis is when vertical with door-plate 2 planes, and the center of gravity of door-plate 2 closed conditions is the highest, and under the gravitation effect, door-plate 2 will be opened voluntarily and make center of gravity drop to the stable state of minimum point, realize the automatic purpose of opening of door-plate 2.Displacement runner 5 drives displacement axle 4 suitable, de-rotation β angles, and when β is 0 or 90 when spending, displacement runner 5 location can be driven or close automatically door-plate 2 automatically, form its semi-automatic function; When β was between 0～90 degree, door-plate 2 had automatically to open and closes function.

Claims

1, a kind of automatic opening/closing door of forming by fixed rotating shaft (1), door-plate (2), doorframe (3) and free-wheeling system, it is characterized in that: free-wheeling system is cooperated with the axis hole (7) of displacement runner (5) in being arranged on doorframe (3) by the displacement axle (4) that is fixed on door-plate 2 another rotating shafts place and forms, the central axis of displacement axle (4) and the center axis deviation certain angle α of fixed rotating shaft (1), displacement runner (5) is suitable, turn certain angle β counterclockwise.

2, automatic opening/closing door as claimed in claim 1 is characterized in that: the angle [alpha] of being mentioned is 1～6 degree, and β is 0～90 degree.
