Abstract

The utility model discloses an inner sunshade hollow window shutter, comprising a hollow glass, an inner window shutter, a blade turnover mechanism of the window shutter. The blade turnover mechanism comprises a rotary shaft, a turnover wheel and a base. The turnover wheel is fixed on the rotary shaft and is connected with the base through a shaft. The turnover wheel is provided with two limitation edges at the two sides. And the base is provided with two corresponding limitation edges. The limitation edges of the turnover wheel are stopped when falling across the limitation edges on the base. The utility model has the advantages that when the rotary shaft rotates, the turnover wheel fixed on the rotary shaft is driven to rotate, and the blades of the window shutter are driven to rotate consequently. The turnover wheel is subject to two directions of limitation of the base. Therefore, the blades of the window shutter will not rotate any more after rotating in place, with the result that the over turnover of the blades is avoided. The whole blade turnover mechanism has simple structure and is easy to be made.

Description

Built-in sunshade hollow shutter

Technical field

The utility model relates to a kind of medi-empty glass window, establishes the medi-empty glass window of blinds in particularly a kind of.

Background technology

Glass better is widely used in daylighting, the insulation and heat insulation in building such as door, window and room because of its printing opacity, heat insulation and fireproof performance.Because China width of cloth source is vast, building environment difference of living in, requirement to the environmental protection of building, aspect such as safe, energy-conservation and attractive in appearance is more and more higher, the glass of using on it need adapt to different temperature, humidity environment, therefore glass intensity and the structure that is used to build there has been higher requirement, combination property will be got well, and makes it can adapt to various field of employment.Hollow glass is owing to adopt the double-layer glass sealing, and its heat conductivility, thermal insulation, power saving function are fine, and its fireproof performance is better, can adapt to the needs of varying environment, and therefore development is very rapid.

For regulating the printing opacity of medi-empty glass window, generally adopt at present shutter is set in medi-empty glass window, realize by the blinds angle of regulating in the hollow glass.The method of regulating the blinds angle has multiple, blade two sides that are generally blinds connect stay cord, stay cord is fixed on the rotating disc, rotating disc is rotated by axle wherein, axle rotates type of drive by two kinds: a kind of is the tumbler of worm gear and worm screw, but this mode must be offered installing hole on the relevant position of window frame before installation, thereby installation comparatively bothers, sealing is also bad; Also has a kind of rotation of regulating blade of louver window from the glass window outside, thereby change the outside indoor light that penetrates, can keep so whole medi-empty glass window sealing, take up space less and appearance looks elegant, be convenient to clean medi-empty glass window, need not regularly to pull down, clean inner shutter again.

Its structure of blade steering device of above-mentioned external control type hollow window with built-in louver sees that Chinese patent literature CN2687295Y is disclosed, it comprises a steering spindle, one is fixedly arranged on the axis of rotation of the tool spiral sliding tray at steering spindle middle part, a pair of be fixedly arranged on steering spindle two end ends to be used to be the rotary drum of solid blade steering rope, one is set on the axis of rotation and sliding base sleeve that join with described spiral sliding tray cunning, one is installed in the magnet piece on the sliding base sleeve, one sliding seat, one be installed on the sliding seat and inhale the in addition magnet piece of joining mutually with magnet piece, it also includes the regulation and control plate, a pair of screw bolt seat, screw rod, motor, a pair of limiting plate, clasp nut, tip-lever support, push rod, button.This structure can be selected electronic or manual when handling blade steering, and can control from the outside, therefore can guarantee the sealing of hollow glass, but this structure is very complicated, cost of manufacture is high, and controls that a blade left side is turned over or the right side easy mistake when turning over.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency of prior art and a kind of built-in sunshade hollow shutter is provided, and makes the excessive upset that its structure is simpler, can prevent blade.

The utility model solves the problems of the technologies described above the technical scheme that is adopted:

Built-in sunshade hollow shutter, comprise hollow glass, built-in shutter and the blade switching mechanism of shutter, it is characterized in that: described blade switching mechanism comprises rotating shaft, turning wheel and base, turning wheel is fixed in the rotating shaft and axle is connected on the base, turning wheel dual side-edge band two position-limited edges, corresponding two Restricted edge are arranged on the base, and the Restricted edge of turning wheel is run into the Restricted edge on the base and is obstructed.

Adopted the position limiting structure on limit and limit between above-mentioned upset control wheel and base,, multiple spacing form can have been arranged also according to moving runner and spacing these characteristics of base.

Compared with prior art, advantage of the present utility model is:

When rotating shaft is rotated, drive the turning wheel rotation of fixing on it, thereby drive the blade rotation of shutter because turning wheel is subjected to the restriction of two directions of base, so the blade of shutter be rotated in place after no longer rotation, avoided the excessive upset of blade.

The whole blade switching mechanism is simple in structure, is easy to make.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1, built-in sunshade hollow shutter comprises medi-empty glass window 20, built-in shutter 30 and blade switching mechanism 40, and the blade 3 of shutter is by 40 controls of blade switching mechanism.

Blade switching mechanism 40 detailed structure are seen Fig. 2, it comprises upset control wheel 5 and holder 6, upset control wheel 5 one ends are provided with two Restricted edge 51 along circumference two sides, holder 6 is provided with corresponding two

positive stop strips

61,62, fixed strip 54 fixing two stay cords 2 that link to each other with blade 3 two sides are set on it, the

axle

52,53 of upset control wheel 5 by its two end is fixed on the

axis hole

62,63 of two ends of holder 6, and upset control wheel 5 is fixed in the rotating shaft 12 by the hole on it 55 by screw 7.

Above-mentioned hole 55 can have two, can change to another hole like this when a hole is damaged, and also conveniently is used for the hollow shutter of various different sizes.

During usual state, upset control wheel 5 is seen Fig. 4 with the position of 6 of bases, the Restricted edge 51 on the upset control this moment wheel and the Restricted edge 61 on the base segment distance of being separated by, and the stay cord 2 that is connected in blade 3 two sides at this moment is parallel to each other.

When shutter need turn left blade, rotating shaft 12 turns left, it is left-handed that rotating shaft 12 drives upset control wheel 5, when upset control wheel 5 rotates to an angle, just limit 5 rotations of upset control wheel during Restricted edge 61 that the Restricted edge 51 on it is run on the holder, at this moment, upset control wheel 5 just can not rotate, therefore Fig. 3 is seen in also no longer rotation of blade 3.

In like manner, when shutter need turn right blade 3, rotating shaft 12 turns right, rotating shaft 12 drives 5 dextrorotation of upset control wheel, when upset control wheel 5 rotates to an angle, just limits the rotation again of upset control wheel during Restricted edge 61 that the Restricted edge 51 on it is run on the holder, at this moment, upset control wheel 5 just can not rotate, so also no longer rotation of blade 3, sees Fig. 5.
