Abstract

The utility model provides a semi-automatic anti-mosquito screen. Rotary shafts whose lower ends are respectively provided with a spring box are arranged symmetrically on the two sides of the existing window frame; gauze is rolled on the rotary shafts; the upper and the lower edges of the existing window frame are respectively provided with a channeled rail whose two sides are matched with flap angles for connecting. The gauze is pulled to slide oppositely along the channeled rail, and the rotary shafts can rotate along with the gauze; the spring is tightened; while in position, the semi-automatic anti-mosquito screen is oppositely connected, and mutually locked by locking buttons, and the semi-automatic anti-mosquito screen is closed; while loosening the locking buttons, the spring is loosened, the rotary shafts can roll the gauze back automatically under the action of spring force, and the semi-automatic anti-mosquito screen is opened. The utility model has the advantages of simple device, easy installation, shapely configuration, and flexible and convenient use. A curtain can be suspended in the semi-automatic anti-mosquito screen, and the semi-automatic anti-mosquito screen is especially suitable for preventing mosquitoes in living rooms in summer.

Description

Semi-automatic anti-mosquito screen

The utility model relates to wing and opens and closes device, particularly semi-automatic anti-mosquito screen window.

The room is a wood frame construction with traditional screen window, changes the push-and-pull of arc formula during use, has not only accounted for usage space but also inconvenience, influences also bad extension curtain attractive in appearance, and need are with a large amount of timber, by carpenter's fabrication and installation.More modern aluminium alloy structure screen window costs an arm and a leg, and ordinary people is not dared to inquire.Release a kind of rolling-gate formula screen window in the market, though this screen window has been done improvement, winding diameter is big, its coiling limit poor sealing performance, and mosquito-proof effect is undesirable, also is unfavorable for the decoration of indoor environment.

The purpose of this utility model provide a kind of laterally to draw, do not account for usage space, installation, easy to use, be suitable for the semi-automatic anti-mosquito screen window generous, that cost is moderate.

In order to achieve the above object, the utility model adopts following solution: at the dual-side of existing window frame, parallel symmetry with window frame is installed the turning cylinder that two lower ends have spring case, the gauze of reeling on the turning cylinder.The upper and lower both sides tankage shape guide rail of window frame, the guide rail two ends connect the activity box angle, spur gauze relatively and slide in the groove of guide rail, and two turning cylinders and then rotate, involutory after putting in place, by the snap close interlocking, at this moment the spring that circles round in two spring cases tightens up, and screen window is closed, unclamp snap close, two spring relaxations that circle round, turning cylinder under the effect of spring force automatically with gauze rollback axle separately on, screen window is opened.

The utility model has the advantages that: 1, because gauze divides two to fan on the turning cylinder that is wound on separately, diameter＜3.5cm, thereby do not account for usage space; 2, framework, guide rail employing are moulded goods and can be saved timber, and be elegant in appearance; 3, use spring turning cylinder winding-structure, divide the laterally pulling of two fans, convenient and strength-saving, light and handy flexibly, also can hang curtain simultaneously; 4, simple in structure, install easily.

Fig. 1 is an overall structure diagrammatic sketch of the present utility model.

Below in conjunction with accompanying drawing the utility model is described in further detail.

As seen from the figure, at upper and lower both sides end near window framework 1 dual-side, be coaxially installed with upper and lower location axle bed 2,3 symmetrically, fixed by self tapping spiral shell fourth, turning cylinder 4 one ends that step is left at two ends stretch in the axle bed 2 of location, and the other end passes spring case 5 and stretches into down in the axle bed 3, near laterally boring Xiao hole 6 near the end, shape is contained in the spring case 5 like the widely different spring 7 that revolves of mechanical watch clockwork spring, and insert in Xiao hole its inner, is tightened up by slotting Xiao.A bit of the colluding in the hole that is reserved in the box wall of outer end bending, it is fixing on framework that spring case 5 passes down axle bed 3 by self tapping spiral shell fourth.The top of gauze 8 sticks on the turning cylinder 4, suitably there is buckle 9 at two edges of pulling out part behind the coiling apart from binding, two edges are embedded in the groove of the upper and lower both sides of doorframe guide rail 10 respectively together with buckle, the guide rail two ends connect dismountable activity box angle 11, gauze is pulled out the terminal two of part slide block 12 is housed, clamping plate 13 clampings of whole limit end, slide block 12 also stretches in the groove of guide rail, two of clamping plate 13 flushes with the guide rail outside, can only in groove, move back and forth to limit gauze, the effect of collapsing flat gauze is arranged simultaneously.Snap close 14 is installed at clamping plate middle parts, when pulling two gauzes to fashionable, stir the snap close interlocking, screen window is closed, and unclamps snap close, gauze is opened from the trend both sides.The 15th, decorative panel, its width and the guide rail outside is wide, plays two effects, and the one, the keep to the side gap of frame of turning cylinder 4 is sealed, prevent that mosquito from creeping into from the gap; The 2nd, constitute the picture frame shape with the guide rail outside, last ornamental thread bar decorative pattern increases aesthetic feeling.Dismountable activity box angle 11, the transversal end face of its transversal end face and guide rail matches, the transversal end face of another transversal end face and decorative panel matches, and the purpose that it is set is to make things convenient for the user can adjust installation flexibly according to the window frame size oneself of oneself.

Claims

1, a kind of semi-automatic anti-mosquito screen window, by window frame, turning cylinder, channled rail, decorative panel, gauze and snap close are formed, it is characterized in that: the turning cylinder that two lower ends have spring case is installed in parallel direction symmetry near the window frame dual-side, the gauze of reeling on the turning cylinder, on the window frame, following tankage shape guide rail, the guide rail two ends connect the activity box angle, the pulling gauze slides in the groove of guide rail relatively, two turning cylinders and then rotate, involutory after putting in place, by the snap close interlocking, at this moment the spring that circles round in two spring cases tightens up, screen window is closed, unclamp snap close, two spring relaxations that circle round, turning cylinder under the effect of spring force automatically with gauze rollback axle separately on, screen window is opened.
