The specific embodiment

See also shown in Fig. 1, Figure 1A, a kind of swing door that the utility model provides, it comprises window frame 10, flabellum 20 and two-way torque force device 30, wherein:

Described window frame 10, be embodied as rectangle sealing support body in the present embodiment, be to utilize four section bars and four angle sign indicating numbers to link to form, in fact, this window frame 10 also can adopt other shapes, as circle, semicircle, " day " font etc., no matter but adopt which kind of shape, this window frame 10 all is the sealing support bodys that connected and composed by several frame plates 11.

Described flabellum 20, it has the fan frame 21 that the inner edge shape with window frame 10 matches, and in the present embodiment, this fan frame 21 be a rectangle, and is connected with a stiffener 22 at the point midway that this rectangle is fanned two long limits of frame 21.No matter adopt which kind of shape, be equipped with gauze 23 in the described fan frame 21, and this fan frame 21 also should be provided with an one rotating shaft 24, the two ends of described gyroaxis 24 pivot with the inner edge of this window frame 10 and are connected.Please in conjunction with Fig. 1, Fig. 2, Fig. 2 A, Fig. 3 A, Fig. 3 B, shown in Fig. 3 C, in the present embodiment, this fan frame 21 is grown the limit as gyroaxis 24 with the one bar, this gyroaxis 24 is section bars of a hollow-core construction, and at the two ends of this gyroaxis 24 inner each fix a door-hinge 251,252, these two door-hinges 251,252 are called door-hinge 251 and following door-hinge 252, each door-hinge 251,252 all have thicker body portion 253 and thinner axial region 254, this door-hinge 251,252 body portion 253 is fastened in this gyroaxis 24, and pass screw 256 with this door-hinge 251 with screw 255,252 are fixed on this gyroaxis 24, this door-hinge 251, the projection from the body portion 253 of 254 of 252 axial regions is come out, and forms with window frame 10 and to articulate.In addition, on this between inwall of the body portion 253 of door-hinge 251 and this gyroaxis 24, also axially leave two passages 26 along this gyroaxis 24.

Described two-way torque force device 30, in the present embodiment, comprise two torsionsprings 31, fixed block 32, with two block seats 33, wherein: this fixed block 32 is fastened in this gyroaxis 24, and pass screw 322 by screw (not giving diagram) this fixed block 32 is fixed in the gyroaxis 24, shown in Fig. 4 A, Fig. 4 B, Fig. 4 C institute, also be provided with two axial perpendicular apertures 321 with this gyroaxis 24 on this fixed block 32; This torsionspring 31 is integrative-structures, connect and compose by two the first arm 311 and second arms 312 that extend to different directions, this the first arm 311 passes in above-mentioned two passages 26, and to these gyroaxis 24 inner extensions, the end of this first arm 311 also is bent with a hook portion 313, this hook portion 313 is plugged in one of them aperture 321 of this fixed block 32, thereby fixedly connected an edge 211 extensions that 312 on second arm of this torsionspring 31 joins with this gyroaxis 24 on this fan frame 21 by described fixed block 32 with this gyroaxis 24; These two block seats 33, one of them block seat 33 is installed in the outer rim of above-mentioned edge 211, another block seat 33 is installed on this window frame 10 inner edge with above-mentioned edge 211 corresponding frame plates 11, stagger mutually in the installation site of two block seats 33, promptly, the distance of two block seats 33 and gyroaxis 24 is also inequality, in order to avoid flabellum 20 and window frame 10 be counterrotating the time, two block seats 33 interfere and damage or can't use; And, wherein second arm 312 of a torsionspring 31 simultaneously with the same sides of two block seats 33 (as the inboard, be towards reader's one side among Fig. 1) contact, 312 whiles of second arm of another root torsionspring 31 contact with the opposite side (as the outside) of these two block seats 33.

By adopting said structure, when flabellum 20 relative window frames 10 are opened to the inside, at this moment, second arm 312 of torsionspring 31 is in the outer part stopped by the block seat 33 that links to each other with window frame 10, make it produce the increasing counter-force of reversing along with the increase of windup-degree, and the reversing counter-force and will force this flabellum 20 to produce the trend of replying of its generation to initial position, and the relative angle between the first arm 311 of torsionspring 31 in the inner part and second arm 312 does not change, the extra counter-force of reversing can be provided, even it has certain pre-torsion, its second arm 312 also can be stopped by the block seat 33 that links to each other with flabellum 20; Open laterally and work as flabellum 20 relative window frames 10, at this moment, second arm 312 of torsionspring 31 is in the inner part stopped by the block seat 33 that links to each other with window frame 10, make it produce the increasing counter-force of reversing along with the increase of windup-degree, and the reversing counter-force and will force this flabellum 20 to produce the trend of replying to initial position of its generation.Therefore, this flabellum 20 not only can bidirectional opening, and no matter open inwardly or outwardly, in case lose the external force of opening flabellum 20, this flabellum 20 all can automatically revert to the position parallel with window frame 10.

For second arm 312 that makes torsionspring 31 can be in the process of flabellum 20 foldings, contact with 33 switchings of two block seats, two block seats 33 preferably all are made as thick, the middle thinner shape in two ends, in order to avoid the slippage from the block seat 33 in the process of flabellum 20 foldings of second arm 312 of torsionspring 31.

Can automatically revert to the position parallel in order to ensure flabellum 20 with window frame 10, the utility model also has at least one pair of magnet 40 in window frame 10 and flabellum 20 corresponding fixed-site, each has opposite polarity respectively to magnet 40 relative ends, by the principle that there is a natural attraction between the sexes between the magnet 40, guarantee that flabellum 20 automatically replies the accuracy of position.Better for the locating effect that makes magnet 40, this pair of magnet 40 is preferably disposed on window frame 10 and the side of flabellum 20 away from this gyroaxis 24.

Above embodiment describes the utility model; but not do restrictive summary; those of ordinary skills are under the guidance of inventive concept of the present utility model; can also make modification and replacement on a lot of conventional structures; for example both can do screen window and also can do the screen door use, these are revised with replacement and also should be considered to belong among the protection domain of the present utility model.
