The utility model is composed of a frame 1, a slideway 2 connected with the frame 1, and a screen 3 which can slide in the slideway 2. The utility model is characterized in that the upper and the lower crossbeams of the frame 1 are respectively connected with shaft fixing plates 4, 5; the ends of bearing shafts 6, 7 are inserted into shaft holes of the shaft fixing plates 4, 5; a screen rolling shaft 8 is arranged outside the bearing shafts 6, 7, and axes of the three shafts are in the same straight line; concave grooves 9, 10 arranged on both ends of the screen rolling shaft 8 are respectively provided with a spiral spring 11; one end of the screen 3 is connected with the screen rolling shaft 8, and the other end is provided with a drawbar 12. The utility model has the advantages of convenient installation and use, no need of storage, and small volume.

Description

Semi-automatic screen door, window

The utility model relates to a kind of screen door, window, especially a kind of semi-automatic screen door, window.

Present screen door, window, mostly be to install gauze at the glass position place that has now on door, the window, so just need two cover door and windows, and existing screen door, window be that day heat is set up, and day cold taking off installed pretty troublesome back and forth, need special keeping after taking off again, if be directly hung on doorframe, the window frame with the yarn curtain, then exist poorly sealedly, can not prevent the disadvantage of mosquito, fly fully.

The purpose of this utility model will not need along with install and remove season repeatedly semi-automatic screen door, the window that can stop mosquito, fly to enter the room fully for people provide a kind of exactly.

Technical solution of the present utility model is: a kind of semi-automatic screen door, window, it is by framework 1, the slideway 2 that is connected with framework 1, and the gauze 3 that can slide in slideway 2 is formed, it is characterized in that: on the framework 1, lower transverse beam respectively with axis fixing plate 4,5 are connected, at axis fixing plate 4, insert bearing shaft 6 in 5 the axis hole respectively, 7 termination,

bearing shaft

6,6 outside is a volume yarn axle 8, and three axis is on same straight line, groove 9 at volume yarn axle 8 two ends, 10 places are equipped with scroll spring 11 respectively, one end of gauze 3 is connected with volume yarn axle 8, and the other end is equipped with draw bar 12.

Spring 14 is equipped with at axis hole 13 places of described volume yarn axle 8, is separately installed with bearing 15 at the two ends of volume yarn axle 8.

Connector 16 on the described draw bar 12 can be connected with the connector 17 that is positioned at framework 1.

The cross sectional shape of the axis hole on the described axis fixing plate 4,5 should be a polygon, and the insertion termination of

bearing shaft

6,7 is corresponding polygon.

Because the utility model is equipped with scroll spring on volume yarn axle, therefore the gauze that draws back when unclamping after automatically rollback to rolling up on the yarn axle, and needn't be again along with season loading, unloading screen door, window back and forth, again owing to the axle head in bearing shaft is equipped with spring, so can change gauze easily, the utlity model has easy to use, need not collect the advantage that volume is small and exquisite.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the front view of the semi-automatic screen door of the utility model, window;

Fig. 2 is the vertical view of the semi-automatic screen door of the utility model, window;

Fig. 3 is the A-A sectional view of Fig. 1.

As shown in Figure 1, framework 1 is fixed on doorframe or the window frame by the installing hole on it 18, axis fixing plate 4,5 link together with framework 1 and fixed head 23 respectively, bearing shaft 6 as shown in Figure 2, a termination of 7 is that square inserts axis fixing plate 4 respectively, in the square axis hole on 5, certain this axis hole and bearing

shaft

6,7 cross section, termination also can be other polygon, as long as can guarantee bearing

shaft

6,7 with axis fixing plate 4, do not relatively rotate just between 5,

bearing shaft

6,7 the other end is inserted in the axis hole of volume yarn axle 8, and spring 14 is housed in the bottom of this axis hole, so that can unload last volume yarn axle 8 at any time, gauze 3 is cleaned or changes, groove 9 at volume yarn axle 8 two ends, be separately installed with scroll spring 11 in 10.So that gauze 3 automatic rollbacks; Bearing 15 is equipped with at two ends at volume yarn axle 8 respectively, and is smooth and easy with the rotation that guarantees volume yarn axle 8.As shown in Figure 3, hold-down screw 19 is being installed to be fixed in the rope on the volume yarn axle 8 on the volume yarn axle 8, this rope is fastened with the rope that is fixed on the gauze 3, just gauze 3 has been connected together with volume yarn axle 8, gauze 3 also can adopt other suitable connected mode with being connected of volume yarn axle 8, as long as the two is linked together.

As Fig. 1, shown in Figure 2, another limit and draw bar 12 relative with volume yarn axle 8 on the gauze 3 are fixed together, and connector 16 is installed on draw bar 12, as hook, on framework 1, connector 17 is installed with connector 16 corresponding positions, as link up with bearing pin, to guarantee that gauze 3 can overcome the convergent force of scroll spring 11 and be in expanded position, the both sides up and down of gauze 3 are wound in respectively on the rubber-like bar-shaped object, as cotton rope, plastic ties or rubber bar, be embedded into again in the slideway 2, to guarantee that gauze 3 can either slide in slideway 2, do not harm again on the gauze 3 reel-to-reel yarn axles 8, also can be on gauze 3, following both sides are sewed on globule and are embedded in the slideway 2 again, and as shown in Figure 3, slideway 2 is fixed on the framework 1 by screw 20.

As shown in Figure 2, can install one outside volume yarn axle 8 and decorate door 21, this decoration door 21 can be connected on the fixed head 23 by hinge 22, and this decoration door 21 can be fan-shaped, also can be rectangle or other shape attractive in appearance.

During use, gauze 3 is pulled out, connector 16 is connected together with 17, just fixed gauze 3, and formed screen door or screen window by draw bar 12; After connector 16 and 17 is unclamped, the just automatic rollback of gauze 3, and need not unload screen door or screen window again.
