Description

Rolling mosquito screen

The utility model relates to a kind of antimosquito window, specifically is the takeup type antimosquito window.

The mosquito-proof facility of existing building construction generally is to adopt wooden screen door and window, or gauze directly is fixed on the window wooden frame with drawing pin, and these anophelifuge devices had both expended timber, cost is high again, takies the interior space when windowing, the collection inconvenience of changing according to the season, also bad washing, and not attractive in appearance yet.Solved the problems referred to above though the patent No. is 92212694.1 takeup type antimosquito window, the problem that exists periphery not seal does not really reach mosquito-proof purpose, and unpick and wash also very inconvenient.

The purpose of this utility model just provides a kind of novel coiling formula antimosquito window, and good airproof performance really reaches mosquito-proof purpose, and easily unpicks and washes.

The technical solution of the utility model is: comprise gauze, fixing wound mechanism and driving mechanism, wherein two ends are fixed on the central spindle of the spring on the bearing spider and are with helical spring, and in the rotating reel of packing into together, a helical spring end is fixed on the mandrel, the other end is fixed on the reel, crosspiece is housed below bearing spider, the upper end of gauze is contained on the reel, about be provided with the open cavity guide rail that can be fixed on the window frame, the straight locking bar of its diameter greater than the guide openings well width is housed in the cavity of guide rail, the two ends, the left and right sides of gauze are provided with the hollow cylinder that can be enclosed within on the locking bar, the cross locking bar that is connected with slide block is housed in the lower end of gauze, slide block cooperates with guide rail, and turn buckle is equipped with in the bottom of guide rail, on the cross locking bar clip is housed.

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

At first to description of drawings:

Fig. 1 represents structure chart of the present utility model;

The A-A sectional drawing of Fig. 2 presentation graphs 1;

The I portion enlarged drawing of Fig. 3 presentation graphs 1;

The B-B sectional drawing of Fig. 4 presentation graphs 3.

Referring to accompanying drawing 1, gauze (9) is wound on the reel (5) at ordinary times, and helical spring (4) is in relaxed state.Spur the cross locking bar (20) of gauze (9) lower end downwards, slide block (19) moves along guide rail (8), gauze (9) drives reel (5) on the one hand and rotates, the helical spring (4) that one end is connected with reel (5) is screwed, stored energy, simultaneously, the hollow cylinder (16) at gauze (9) two ends, the left and right sides is enclosed within on the locking bar (17), after gauze (9) is pulled to the position, rotate turn buckle (10), turn buckle (10) combines with clip (11), and gauze (9) is located, gauze (9) is about to the window sealing, shown in Fig. 3,4.Because gauze (9) has crosspiece (1), cross locking bar (20) up and down respectively, it is very open and flat after gauze (9) is launched, and the hollow cylinder of the left and right sides (16) is enclosed within on the interior locking bar (17) of guide rail (8), make the periphery of gauze (9) form good closed state, really reach mosquito-proof purpose.In the time of need windowing, rotate turn buckle (10), discharge gauze (9), the helical spring that screws (4) beginning work done promptly drives reel (5) rotation, and gauze (9) just on reel (5), just packed up automatically with the rotation of reel (5) by gauze (9).The expansion of gauze (9) and pack up all and slide in guide rail (8) by slide block (19), motion is convenient freely.

Unpick and wash for convenience, the utility model is equipped with ratchet mechanism between bearing spider (2) and reel (5), wherein ratchet (14) is enclosed within on the bearing spider (2), and reel (5) is connected with ratchet (14), ratchet (13) cooperates with ratchet (14), as shown in Figure 2.When gauze (9) launched or packs up, reel (5) and ratchet (14) rotated together, when needs are unpicked and washed gauze (9), propped up ratchet (14) with ratchet (13), can keep spring potential energy and unlikely release is taken off washing with gauze (9).After washing gauze (9) is installed to reel (5) again and upward just can normally use, very convenient.

The utility model has the pull bar (21) that is connected with slide block (19) in cross locking bar (20) below, and stay cord (12) is housed on the pull bar (21), and movable button (11) is contained on the pull bar (21), shown in Fig. 1,3, when gauze (9) is launched, by pull bar (21) pulling, after launching to put in place, turn buckle (10) can be locked on the movable button (11) of pull bar (21), simple in structure, easy to use, for higher door and window, utilize stay cord (12) pulling pull bar (21), very convenient.

Gauze of the present utility model (9) adopts velcro (15) to connect with reel (5), and as shown in Figure 2, gauze (9) dismounting easily.

The novel coiling formula antimosquito window that the utility model provides is simple in structure, and modern design is easy to use, gauze carries out auto reeling by spring assembly, very convenient, it is smooth, attractive in appearance that gauze launches the rear surface, peripheral good airproof performance, really played mosquito-proof effect, during rolling, the two ends balance can be not crooked, also very convenient simultaneously disassembly, cleaning are a kind of convenience, practicality, commodity attractive in appearance.
