The ratchet rack type wind-proof window catch disclosed by the utility model is applied to multi-position location when the window sash is open and can be used for automatically closing the window sash when the wind is relatively powerful.
Description
Technical field
The utility model relates to Windproof window hook, is specifically related to a kind of ratchet bar formula Windproof window hook.
Background technology
The ratchet bar formula Windproof window hook that open angle of window can arbitrarily be adjusted and can automatically be closed by wind-force in the market, as the application number automatic wind-proof catch that is 94206015.6, while windowing, a hand need to be dialled to ratchet, make ratchet freely, another hand push opens a window to required angle, then unclamp ratchet, make ratchet under the effect of torque spring, block ratchet and realize window location.The shortcoming of this Windproof window hook is: opening a fan window needs two hands to coordinate, very inconvenient for the custom of windowing of respectively pushing a fan window open for direct two hands of people.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of ratchet bar formula Windproof window hook is provided, the multiposition location when can be used for sash and opening, and wind-force can automatic close window fan when stronger.
The utility model comprises window frame fixed head, connecting rod, ratchet, ratchet bar base plate, the axis of guide, sash bearing, spring, pull bar, rocking bar and bracing wire.One end of described connecting rod and window frame fixed head are hinged, and the other end and ratchet are hinged; The bottom of described ratchet is provided with integrated square slider, and square slider is connected by sliding pair with sash bearing; The top of described sash bearing offers ratchet bar base plate resettlement groove; Two axis of guides are separately fixed at the two ends of ratchet bar base plate resettlement groove; Kink is on two axis of guides respectively at the two ends of described ratchet bar base plate, and the width of ratchet bar base plate is less than the width of ratchet bar base plate resettlement groove; One side of described ratchet bar base plate is provided with ratchet bar, and the head of described ratchet embeds between two ratchets of ratchet bar; The opposite side two ends of described ratchet bar base plate are connected with the same sidewall of ratchet bar base plate resettlement groove by a spring respectively; Pull bar and spring are arranged on the same side of ratchet bar base plate; One end of described pull bar and ratchet bar base plate hinged, one end of the other end and rocking bar is hinged; The middle part of described rocking bar and sash bearing are hinged, and one end of described bracing wire is fixed on the other end of rocking bar.
Two described axis of guides be arranged in parallel.
The beneficial effects of the utility model:
Multiposition location when the utility model is opened for sash, thus ventilation controlled; When wind-force is stronger, can fan by automatic close window, thereby prevent that rainwater from entering window or glass damages; One-handed performance just can reach the object of window opened via location, easy to operate.
Accompanying drawing explanation
Fig. 1 is overall structure stereogram of the present utility model;
Fig. 2 is the structural perspective of ratchet in the utility model;
Fig. 3 is the structural perspective of window frame bearing in the utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1,2 and 3, a kind of ratchet bar formula Windproof window hook, comprises window frame fixed head 1, connecting rod 2, ratchet 3, ratchet bar base plate 4, the axis of guide 5, sash bearing 6, spring 7, pull bar 8, rocking bar 9 and bracing wire 10.One end of connecting rod 2 and window frame fixed head 1 are hinged, and the other end and ratchet 3 are hinged; The bottom of ratchet 3 is provided with integrated square slider 3-1, and square slider 3-1 is connected by sliding pair with sash bearing 6; The top of sash bearing 6 offers ratchet bar base plate resettlement groove 6-1; Two axis of guides 5 be arranged in parallel, and are separately fixed at the two ends of ratchet bar base plate resettlement groove 6-1; Kink is on two axis of guides 5 respectively at the two ends of ratchet bar base plate 4, and the width of ratchet bar base plate 4 is less than the width of ratchet bar base plate resettlement groove 6-1; One side of ratchet bar base plate 4 is provided with ratchet bar 4-1, and the head of ratchet 3 embeds between two ratchets of ratchet bar 4-1; The opposite side two ends of ratchet bar base plate 4 are connected with the same sidewall of ratchet bar base plate resettlement groove 6-1 by a spring 7 respectively; Pull bar 8 and spring 7 are arranged on the same side of ratchet bar base plate 4; One end of pull bar 8 and ratchet bar base plate 4 are hinged, and one end of the other end and rocking bar 9 is hinged; The middle part of rocking bar 9 and sash bearing 6 are hinged, and one end of bracing wire 10 is fixed on the other end of rocking bar 9.
The operating principle of this ratchet bar formula Windproof window hook:
Window frame fixed head 1 is fixed on to frame bottom, and the lateral wall of sash bearing 6 is fixed on sash, and the other end of bracing wire 10 is fixed on the joystick of sash lock; In the time of need windowing, only need rotate the joystick of sash lock and sash is pushed open, bracing wire 10 tensionings pull rocking bar 9 to swing, rocking bar 9 moves ratchet bar base plate 4 and Compress Spring 7 by pull bar 8, ratchet bar 4-1 is separated with ratchet 3, and now, ratchet bar 4-1 is ineffective, the square slider 3-1 of ratchet 3 bottoms can slide along sash bearing 6, and sash can freely be opened; Push open after sash to desired location, unclamp the joystick of sash lock, ratchet bar base plate 4 is homing under the restoring force effect of spring 7, and ratchet bar 4-1 pushes against ratchet 3, realize sash location, now the joystick of sash lock is got back to initial position under bracing wire 10 effects.When sash has while swinging trend outward under wind-force effect, ratchet bar 4-1 props up ratchet 3, and sash maintains static; When sash has while swinging trend inward under wind-force effect, if wind power energy overcomes the elastic force of spring 7, just the head of ratchet 3 is separated with ratchet bar 4-1, sash automatically swings inward under wind-force effect; If now wind-force does not weaken, swinging direct is to closing inward for sash, if when the abatement of wind extremely can not overcome the elastic force of spring 7, ratchet bar 4-1 pushes against the head of ratchet 3 again, sash is in half-open position.
