Abstract

A folding self lock sash bracket comprises a sash leaf base, a sash sill base, two connecting rods, a movable buckled leaf, a limited stop pin, and a buckled pin. The opening angle of the sash can be adjusted at will, and the sash leaves are pined automatically. The utility model has the advantages of simple structure, and convenient operation. The utility model is suitable for the windows which are opened outwards.

Description

Folding self lock sash bracket

The utility model relates to a kind of folding and self-locking window fastener.

General window is equipped with window catch and latch, fixed casement window leaf position when window catch is used to window now; Latch fastens the window leaf when closing window.Use common window catch and latch, will draw back latch when windowing earlier and window, take window catch again; To unload window catch when closing window earlier and draw the window leaf, insert latch again.And because of limited by window catch, the window leaf can not arbitrarily be fixed in an angle.Therefore, this device is not only loosely organized, open and close window inconvenience, and can not regulate louver angle arbitrarily.

The purpose of this utility model provides a kind of folding and self-locking window fastener, is connected window trichidium and banquet and is constituted by two connecting rods of equal in length, has compact conformation, can regulate louver angle arbitrarily, automatically the characteristics of snap close window leaf.

The utility model is achieved in that installs banquet on windowsill, device elasticity activity cramp reaches the resistance pin that is used with movable cramp on the banquet; On window leaf base the window trichidium is set, window trichidium upper punch is shaped on the button pin.Connecting rod by two equal in length between banquet and the window trichidium is connected, and two connecting rods can fold mutually.Banquet and window trichidium are connected with connecting rod, and connecting rod with take moveable hinge being connected of connecting rod respectively, the hinge of sliding, elastic damping hinge rivet.In connecting rod and connecting rod junction, the interlinking lever end that is connected with banquet is established a spacing resistance pin.Because the connection between connecting rod, banquet, the window trichidium is riveted structure, two connecting rods can fold, and the effect of the movable cramp on the banquet in addition makes open and close window leaf flexible.When windowing, pull open the movable cramp on the banquet, just with the outside support of window leaf.The a certain angle of desiring to window, as long as the window leaf is pushed into this angle, the damping force at two rod hinge connection places can be kept the window leaf in this position under the little situation of wind.When closing window, the window leaf is retracted, two connecting rods are overlapping, and the button pin on the window trichidium is run into the elasticity activity cramp on the banquet, overcomes its elastic force, slip in the movable cramp along the inclined-plane of cramp, window can be fastened.Meet the strong wind certain angle of still need windowing, earlier the window leaf is opened to maximum position (two connecting rods time) in line, with hand connecting rod elastic damping hinge is stirred an angle to the window limit, its spacing resistance pin can be given window leaf location.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is a schematic diagram of the present utility model;

Embodiment: with reference to Fig. 1, the folding and self-locking window fastener is mainly by banquet ［ 3 ］, window trichidium ［ 7 ］, connecting rod ［ 4 ］ and ［ 6 ］ formation.It is stepped that banquet ［ 3 ］ is secondary, and its low order and connecting rod ［ 4 ］ are riveted with moveable hinge; Device resistance pin ［ 2 ］ and movable cramp ［ 10 ］ on the high-order.Resistance pin ［ 2 ］ is a duckpin.Movable cramp ［ 10 ］ is hook-shaped, on an inclined-plane and spring ［ 11 ］ are arranged, with moveable hinge ［ 9 ］ it is riveted on the banquet ［ 3 ］.Connecting rod ［ 6 ］ is taked elastic damping hinge ［ 5 ］ riveted joint (connecting rod ［ 6 ］ is last) with connecting rod ［ 4 ］, with window trichidium ［ 7 ］ hinge ［ 8 ］ riveted joint of sliding.Window trichidium upper punch is shaped on button pin ［ 13 ］.Be about to window trichidium ［ 7 ］ punching out one-tenth " recessed " shape, its long side surface is in order to fix with the window leaf, and short side is as button pin ［ 13 ］, and the bottom surface is used for dress slip hinge.In riveted joint place of two connecting rod elastic dampings hinge, connecting rod ［ 4 ］ is gone up limited steric hindrance pin ［ 12 ］.Making spacing resistance pin ［ 12 ］, is when making connecting rod ［ 4 ］, and a fritter is outwards protruded on the bent limit of one end, again this fritter is pulled upwards.Each parts is all used the metal manufacturing, and window trichidium and banquet are separately fixed on window leaf and the windowsill with screw.

Claims

1, folding and self-locking window fastener, selling, buckle pin by window trichidium, banquet, connecting rod, movable cramp, spacing resistance pin, resistance constitutes, it is characterized in that between window trichidium and the banquet that by two equal in length the connecting rod that can fold mutually connects, connecting rod all can freely rotate in each junction; The window trichidium is provided with the button pin; Banquet is stepped, above the resistance pin that installs hook-shaped elasticity activity cramp and be used with movable cramp.

2, folding and self-locking window fastener according to claim 1 is characterized in that two connecting rods connect to take the riveted joint of elastic damping hinge, two connecting rods to be connected with window trichidium, banquet to take respectively to slide to cut with scissors and moveable hinge is riveted.

3, folding and self-locking window fastener according to claim 1 and 2 is characterized in that two rod hinge connection places, with limited steric hindrance pin on the connecting rod that banquet is connected.
