Description
Technical field
The utility model relates to a kind of door folding, specifically, is a kind of folding that automatically resets.
Background technology
The door folding of prior art does not have automatically reset function, and door needs after opening the people for closing, but many times because a variety of causes causes door to forget closes or be not closed completely, makes troubles for work or life.For overcoming this shortcoming, people have also proposed some technical solutions, more common is that the between the walls increase is provided with elasticity reset device behind door and door, door is opened the back can return under the effect of elasticity reset device, structure is complicated, cost is big, the problem of trouble is installed but exist, versatility is restricted in addition, and some door is not suitable for installing this type of device.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to use, folding that automatically resets that universal performance is good.
The utility model is achieved in that a kind of folding that automatically resets, comprise two page or leaf sheets that connect by rotating shaft, it is characterized in that: on this one of them page of folding sheet fixed cover is set, spring push-rod is set in the fixed cover, the catch that matches with the spring push-rod end face is set on another page sheet, and in the folding opening procedure, spring push-rod is headed in the fixed cover by catch, do the time spent when losing external force, folding automatically resets under the effect of spring push-rod elastic force.
Further improve as the utility model, this spring push-rod comprises spring and push rod, and spring one end is enclosed within on the push rod, and the other end contacts with spacer on being arranged on fixed cover.
Further improve as the utility model, this push rod end face comprises cambered surface section and planar section.
Further improve as the utility model, wherein one page sheet and rotating shaft are for flexibly connecting, and this page sheet can be by taking off flexibly in the rotating shaft.
The utility model directly is provided with the spring push-rod structure on existing folding body, door opening procedure medi-spring push rod is compressed, and produces elastic reactance, and after external force disappeared, door can reset under the elastic force effect.The utility model can be widely used on the door of various doors or other band doorframe, has advantage simple in structure, easy to use, that versatility is good.

The specific embodiment
As shown in the figure, two pages of sheets 1 connect by rotating shaft 2, and fixed cover 3 is set on one of them page sheet 1, in the fixed cover 3 spring push-rod is set, spring push-rod comprises spring 4 and push rod 5, and spring 4 one ends are enclosed within on the push rod 5, and the other end contacts with spacer 6 on being arranged on fixed cover 3.The catch 7 that matches with push rod 5 end faces is set on another page sheet 1.These push rod 5 end faces comprise cambered surface section 8 and planar section 9.In the folding opening procedure, push rod 5 is headed in the fixed cover 3 by catch 7, when two pages of sheet 1 angles during less than 180 °, catch 7 is the oblique angle with the contact angle of push rod 5 end faces, this moment, folding automatically reset under spring 4 elastic force effects when losing external force, and door can be closed automatically.When two pages of sheet 1 angles during more than or equal to 180 °, the contact angle of catch 7 and push rod 5 end faces is a vertical angle or near vertical angle, does the time spent when losing external force, and folding can keep balance in this position, and door can be in normally open.
Diagram fixed cover 3 and spring pusher arrangement are two, during practical application, also can be designed as one or more according to the folding size.Diagram fixed cover 3 and catch 7 constitute by page or leaf sheet 1 direct bending fold, during practical application, also can be designed as independent structure, adopt modes such as welding, riveted joint to be connected and fixed with page or leaf sheet 1 again.
This folding mounting means and existing folding are slightly different, and prior art page or leaf sheet 1 is that a slice is fixed on the doorframe, and another sheet is fixed on the side rib of door, and this folding wherein is not installed on the doorframe with the page or leaf sheet 1 of fixed cover 3, and another sheet is installed on the back side of door.
For the place of needs door for convenience detach, folding can be designed as dismantled and assembled structure, and wherein one page sheet 1 is flexible connection with rotating shaft 2, and this page sheet 1 can be by taking off flexibly in the rotating shaft 2.No longer carrying out accompanying drawing at this represents.
Claims (4)
1, a kind of folding that automatically resets, comprise two the page or leaf sheets (1) that connect by rotating shaft (2), it is characterized in that: on this one of them page of folding sheet (1) fixed cover (3) is set, fixed cover is provided with spring push-rod in (3), another page sheet (1) is gone up the catch (7) that matches with the spring push-rod end face is set, and in the folding opening procedure, spring push-rod is headed in the fixed cover (3) by catch (7), do the time spent when losing external force, folding can automatically reset under the effect of spring push-rod elastic force.
2, the folding that automatically resets according to claim 1 is characterized in that: this spring push-rod comprises spring (4) and push rod (5), and spring (4) one ends are enclosed within on the push rod (5), and the other end contacts with spacer (6) on being arranged on fixed cover (3).
