Description

Automatic closing and shading curtain

Technical Field

The invention relates to the technical field of windows, in particular to a curtain capable of automatically closing to shade.

Background

The outer glass layer of mostly designing into of modern office building, the glass wall is lighter than in the entity wall, and the field of vision daylighting is all fine, glass curtain wall light transmissivity is very good, but there is certain drawback to the staff in the office building, strong light shines and can reflect light on office staff's the computer screen, the user can be difficult to see the problem on the display screen clearly, and sit the office staff who leans on the window position for a long time, because broiling of sunshine, very easily by the suntan sunburn, glass curtain wall printing opacity shines and can influence the vision in office staff's the eyes, make and look the thing difficult.

Therefore, the curtain is generally installed in front of the glass window to shield sunlight so as to facilitate office work, but in practice, the indoor space of an office building needs the outside sunlight to provide good illumination, and meanwhile, the direct irradiation of too strong sunlight needs to be avoided.

Disclosure of Invention

The invention aims to solve the defects in the prior art, such as: a glass curtain wall of an office building, and provides a curtain capable of automatically closing a sun-shading window.

In order to achieve the purpose, the invention adopts the following technical scheme:

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1-3, an automatic closing sun-shading curtain comprises a window frame 1 and a plurality of window curtain strips 2, wherein two ends of the window curtain strips 2 are rotatably installed in the window frame 1, two sides of the window frame 1 are symmetrically provided with a plurality of rotating cavities 4 corresponding to the window curtain strips 2, two ends of each window curtain strip 2 are fixedly connected with rotating shafts 3, the rotating shafts 3 are rotatably inserted in the rotating cavities 4, the rotating shafts 3 are provided with notches 5, the notches 5 are positioned in the rotating cavities 4, adjusting bodies 6 are arranged in the rotating cavities 4, each adjusting body 6 comprises a storage tank 7 and a corrugated pipe 8, the adjusting bodies 6 are filled with elastic gas, and a spring is arranged at the connecting part of each rotating shaft 3 and the inner wall of the window frame 1;

wherein, bellows 8's upper end and holding tank 7 intercommunication, bellows 8's lower extreme and stubborn mouthful 5 fixed connection, bellows 8 sets up the rightmost side at holding tank 7, be used for depositing elastic gas in the holding tank 7, because holding tank 7 shape is fixed, gas after the thermal expansion can flow in to bellows 8, then corresponding bellows 8 is propped up by gas, stubborn mouthful 5 will be atress unbalanced, bellows 8 after propping up can promote stubborn mouthful 5 and rotate, elastic gas is nitrogen gas, the material of holding tank 7 is thermosetting plastic, the best and nontoxic gas of thermal expansion effect is hydrogen, helium, nitrogen gas, but hydrogen is flammable, helium is very expensive, nitrogen gas, it is not noble, can be in a large number on the (window) curtain of application and office building, safe practical and cheap.

Wherein, the window frame 1 is gone up and is provided with the glass piece with the relative position in rotation chamber 4, window frame 1 one side outwards sets up to glass, then the sunlight of outside can be smooth see through the glass piece, thereby the light energy of sunlight can heat inside elastic gas, curtain strip 2 includes frame and shading cloth, shading cloth is thermal-insulated cloth, thermal-insulated cloth's surface scribbles black coating, shading cloth fixed mounting is in the frame, whole curtain strip 2 comprises frame and thermal-insulated cloth, can effectually play the thermal-insulated effect of sunshade, and black coating has better endothermic effect.

In the invention, when a user uses the device, when the external light is better, particularly when the sunlight is directly radiated, the corresponding light irradiated on the curtain strip 2 is very strong, the curtain strip 2 in the initial state is in the state of unfolding in an inclined upward manner, at the moment, because the strong light is irradiated on the curtain strip 2 and the window frame 1, namely when the light is strong to influence indoor office staff, the corresponding light irradiated in the rotating cavity 4 is also stronger, the storage tank 7 in the rotating cavity 4 stores elastic gas which is nitrogen, the nitrogen expands under the heating, the nitrogen stored in the storage tank 7 expands under the heating action of the sunlight, the volume of the nitrogen expands, and the storage tank 7 is made of thermosetting plastic, so that the gas which is increased in volume can enter the corrugated pipe 8 along with the corresponding deformation of the expansion of the gas, bellows 8's initial state is the folding contraction state, can stretch out after the gas expansion of inside, bellows 8 will extend, bellows 8 is connected and is being located the position on stubborn 5 rightmost side, pivot 3 is the structure that can free rotation, bellows 8 is to stubborn 5's effort, one side of stubborn 5 will obviously atress, then stubborn 5 will rotate under bellows 8's effort, then corresponding pivot 3 can rotate, curtain strip 2 will rotate under the 3 combined action in pivot at both ends, the elasticity of spring is overcome in order to rotate to curtain strip 2's rotation, then curtain strip 2 will be corresponding to be put down from the expansion state, thereby can block sunshine, play the effect of sunshade, the effectual inconvenience of avoiding the office staff to receive the direct projection of sunshine and bring.

When external sunshine is not directly irradiated to the window frame 1 any more, the temperature in the corresponding rotating cavity 4 is reduced, the gas in the adjusting body 6 is correspondingly heated, the corresponding volume of the elastic gas after the temperature is reduced is contracted, the shape of the storage tank 7 is not changed, the shape of the corrugated pipe 8 is changed, the corresponding corrugated pipe 8 is contracted and folded to adapt to the change of the gas volume, the notch 5 is not subjected to the acting force of the corrugated pipe 8 any more, the corresponding curtain strip 2 is supported under the action of elasticity to be unfolded, and the external sunshine can be irradiated again.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
