Abstract

The utility model relates to an automatically rolling screen door, which utilizes reel springs to drive a winding drum to rotate by a reel guide pulley which is arranged on the bottom plate of the window box. Tension springs are arranged on both ends of the winding drum to cause that after being installed, the green screening has definite elasticity, and an open automatic positioner is arranged on a lower window frame. The utility model has the advantages of simple and compact structure, automatic curtain-rolling and convenient operation, which is a device for preventing ash, flies, mosquitoes entering the room, being suitable for houses, hotels, hostels, office buildings and other public places.

Description

Automatically rolling screen doors

Automatic curtain formula screen window and door of the present utility model belongs to a kind of daily light industry industry product, is applicable to that hotel, hostel, hospital, shop, office and civilian window prevent dust, a kind of facility in the worm inlet chambers such as fly, mosquito.

Summer for prevent that mosquito inlet chamber internal ratio ideal method from being that air curtain is installed above door and window, it can form invisible air wall one, not only can prevent from can also play the effect of isolating chamber internal and external temperature in the mosquito inlet chamber, this method has been adopted in some luxurious hotels and the market of China.But its consumed power involves great expense, and is difficult to enter huge numbers of families.Current general employing rotary type screen door and window prevents in the mosquito inlet chamber, need to consume certain timber but make, cost is higher, and occupation space is bigger when opening after installing, special when green yarn is tightened after inductility, to bump on green yarn be not that to be out of shape be exactly to break to thing firmly.So use also not ideal.

The purpose of this utility model provides a kind of simple and compact for structure, the screen window and door of automatic curtain formula.

Fig. 1 is an automatic curtain formula screen window and door general assembly drawing.

Fig. 2 is any localization machine composition.

Fig. 3 is for opening positioner figure.

The utility model is finished as follows, the automatic shutter type screen window and door adopts two of spool spring (1) to link to each other with spool rope (5), it is connected with reel roller bearing (3) by the spool guide wheel (2) that is fixed on the window box plate (6), reel (8) closes roller stand (4) Free on the base plate (6) by being fixed on window, reel can roll with iron sheet, also can use plastic production, the reel roller bearing (3) of roller stand (4) outside twines spool rope (5), twine positioning rope (13) between roller stand (4) and the reel (8), its winding direction is opposite, utilizes the pulling force of spool spring (1) to make reel (8) automatic curtain. Be fixed on reel (8) around the green yarn, green yarn tensioned lines (12) and drawing the dawn on (11). Positioning rope (13) encloses in upper its two of the driving wheel (17) of opening locating device (15) and links to each other with reel roller bearing (3) by being fixed on the positioning guide wheel (14) in the window frame (10) and twining one, driving wheel (17) can only cut out Free on the direction of screen window, window frame can adopt the material of iron sheet, aluminium alloy to make, and also can make of duroplasts. (9) one of tensioning springs are fixed on the edge of reel (8), and the other end links to each other with green yarn tensioned lines (12), when (11) closing window is drawn the dawn in pulling, draw the dawn bonnet lock hole (16) on (11) Lock mutually with the tongue (22) on the opening locating device (15), close screen window. At this moment tensioning spring (9) plays on the one hand the effect of tightening green yarn, on the other hand when External Force Acting during in green yarn, and within the specific limits high resilience, and be unlikely to bump brokenly green yarn. Pulling handle (25) band is employed pin (21) and is fixed on ratchet (20) on the positioning ratchet wheel (23) and breaks away from locating latch face (18) on the driving wheel (17) when windowing, make driving wheel (17) Free, at this moment also release lock button hole (16) simultaneously of tongue (22), at the green yarn of spool spring (1) effect lower mandrel member (8) scrolling, open screen window. When release handle (25) under the effect of return spring (24), ratchet (20) is by inserting locating latch face (18) under the effect of ratchet spring (19), driving wheel (17) stops operating, at positioning ratchet wheel (23) two ratchets (20) are arranged, two locating latch faces (18) also should be arranged on driving wheel (17) mutually, at this moment the stop operating frictional force of rear generation and the pulling force that spool spring (1) produces of positioning rope (13) and driving wheel (17) balances each other, and the screen window enable possition is fixed, spool spring (1) also plays the effect of tensioning spring (9) simultaneously, green yarn still has certain elasticity, when haul handle (25) when not loose always, screen window is all opened.

Automatic curtain formula screen window and door provided by the utility model and existing screen window and door compare and have tangible advantage, it is simple and compact for structure, automatic curtain, automatically locate, easily manufactured, save timber, green yarn has certain elasticity after installing, not taking up space, is that a kind of desirable apparatus of mosquitos and flies is kept away in public places such as family, hotel, hotel, office building.

With stopper wood screw or swell fixture window box plate (6) and window frame (10) are fixed on the window wall, because the unlatching of screen window and door is a roller shutter type, its automatic curtain device can all be installed in the case (7), therefore can't see roller blind device from appearance, stay-supported casement device can also be installed on the case (7), use elegant in appearancely like this, case (7) available iron leather is made, also can be with duroplasts or three-ply board manufacturing.When automatic curtain formula screen window and door being revolved when turning 90 degrees, of reel roller bearing (3) thrust bearing is installed, just can be used as the screen door use, and can save the unlatching positioner, so more can reduce cost, its switch is flexible, is applicable to huge numbers of families.
