Abstract

The utility model relates to a wind-proof window hook, which is used for the opening and the positioning of a window sash and can automatically be closed by means of wind force. The utility model is characterized in that a hanging nose is provided with a strip-shaped hole; a supporting rod is hinged by two sections, is folding, and is provided with a ratchet mechanism. The wind-proof window hook solves the problems that the opening angle of the window sash is arbitrary to control ventilation quantity and the window sash realizes self-closing and prevents rain water from flowing into windows and glass from scraping, when wind blows. The utility model can be used for the window installation engineering of buildings.

Description

Automatic wind-proof catch

The utility model relates to a kind of storm window that is used for sash unlatching location, house and can closes automatically by wind-force and colludes.

It is employed for Fixed Window colludes that now the house sash is opened the location, back, and its shortcoming is: (1) opening angle is to fix, and generally being about 90 ° can not the regulated at will ventilation; (2) when blowing and raining, must manually close, owner stays out as the house, then can cause travel fatigue to blow houseful, and rainwater is thrown window into, glass can be broken when serious, even sash be wiped off (especially wooden window).

The purpose of this utility model provides a kind of sash opening angle and can arbitrarily adjust and can collude by the automatic storm window that wind-force is closed automatically.

The purpose of this utility model be achieved in that it by each parts all mutually two of symmetry form a cover, be used in a window about two sash, each is made up of hanging nose, ratchet ┄ strut, ratchet, torque spring, base plate, lid.One bar hole is arranged on the hanging nose.Ratchet ┄ strut is by two sections flexible connections, and there is projection in a paragraph header portion that matches with hanging nose, another section end band one fan-shaped ratchet, and with the rotating shaft activity assembling that is fixed on the base plate.Ratchet, torque spring cooperation are installed on the pawl axis, and ratchet is pushing against on fan-shaped ratchet under the effect of torque spring.Lid is fastened on the base plate.

The utility model has following advantage: (1) can make the sash opening angle arbitrarily adjust, thus the control ventilation; (2) sash is closed automatically when blowing and prevent that rainwater from advancing window and glass scratches.

Elaborate below in conjunction with accompanying drawing:

Fig. 1 is the vertical view of the utility model (right side sash) sash when user mode when opening 90 °.

Fig. 2 is ratchet ┄ pole structure figure.

Fig. 3 is the lid structure chart.

Hanging nose 1 is split with ratchet ┄ strut 2, ratchet 3 etc., hanging nose 1 is installed on the sash, ratchet ┄ strut 2, ratchet 3 etc. are screwed on window frame by base plate 5, the projection of ratchet ┄ strut 2 terminations is inserted in the cylindrical void of hanging nose 1, be fixed with two rotating shafts on the base plate 5, the movable respectively fan-shaped ratchet and pawl 3 that is equipped with ratchet ┄ strut 2, ratchet ┄ strut 2 is divided into two sections and can opens and fold with the sash switching, one section is one with fan-shaped ratchet, a projection is fixed in another section end, and two sections hinged.Ratchet 3, torque spring 4 are contained in the ratchet rotating shaft on the base plate 5 together, have one on the ratchet and dial Xiao, dial Xiao and pass box cover hole and be exposed at outside the lid, torque spring 4 is stuck on the ratchet 3, the other end is stuck in the place of notch together on the base plate, and under torque spring 4 effects, ratchet pushes against on ratchet.Lid 6 usefulness bolts and base plate 5 are fixing.

Mode of occupation: the automatic storm window of two symmetrical configuration is colluded the corresponding respectively suitable position that is installed in left and right sides sash and window frame, the projection of ratchet ┄ strut end is inserted in the cylindrical void of hanging nose.Ratchet ┄ strut was a folded state when sash was closed, and in the time of need windowing, dialled Xiao that dials on the ratchet on the other hand, make the ratchet freedom, another hand push is windowed fan to required angle, then, unclamp Xiao that dials of ratchet, ratchet blocks ratchet and realizes the sash location under the effect of torque spring.When blowing, the sash swing, the projection of ratchet ┄ strut termination slidably reciprocates in the cylindrical void of hanging nose, and when wind-force overcame the torsion of torque spring, strut was folding, and ratchet rotates, and sash is closed under the wind-force effect automatically gradually, till closing tight.

Claims

A kind of automatic storm window colludes, by each parts mutually two of symmetry forms one and overlaps, each is by hanging nose (1), ratchet--and-strut (2), ratchet (3), torque spring (4), base plate (5), lid (6) are formed, and it is characterized in that: hanging nose has a bar hole on (1); Ratchet---strut (2) is by two sections flexible connections, and there is projection in a paragraph header portion that matches with hanging nose, another section end band one fan-shaped ratchet, and with the rotating shaft activity assembling that is fixed on the base plate (5); Ratchet (3), torque spring (4) cooperation are installed on the pawl axis, and ratchet (3) is pushing against under the effect of torque spring (4) on fan-shaped ratchet; Lid (6) is fastened on the base plate (5).
