Abstract

Disclosed is a wind-proof positioning hinge, comprising an A leaf and a B leaf. Deflector rods are sheathed in the A leaf and the hemming of the b leaf. One end of each deflector rod is sheathed with spring, a key groove on the hemming of the lower end of the A leaf and the other end of the deflector rod are in sliding fit, and the other end of the deflector rod is fixed with keys. The hemming of the B leaf, which is connected with the hemming of the lower end of the A leaf, is provided with a key groove. The deflector rod is rotated to drive the keys to be inserted in the key grooves of the two hemmings for fixing position, and the connection is of reliability and is of good wind-proof performance. If the hemming of the B leaf is provided with two or more than two key grooves with different angles, and a corresponding opening angle is formed. The utility model which has the advantages of simple structure and convenient operation is superior to a wind-proof hook without selecting buffers and is used for a door with a wood structure or a cement structure or a window with a wood structure or a cement structure.

Description

Wind-proof hinge combined with braking device

The utility model relates on a kind of structure with hinge and couples together the windproof Positioning hinge of braking.

The present general window hinge that uses, itself does not have positioning action, scraped the fragmentation of shake back for preventing window glass by wind, must buckle anti-window catch, but windproof being hooked in the long-term use, often produce loosening can appearance the unhook, if anti-window catch is installed on the cement window frame, anti-window catch itself is also fastening not too easily.When being close to (promptly parallel) with exterior wall especially after the window page or leaf is opened, can't install, then just be a problem in the location of window page or leaf.

The purpose of this utility model is to increase a kind of detent mechanism on common hinge, can replace windproof hook, and can overcome the problem of above-mentioned existence.

The technical solution of the utility model is: it comprises A page or leaf, B page or leaf, be with driving lever in A page or leaf and the B page or leaf crimping, be with spring between nut on the driving lever one end axle and A page or leaf upper end crimping end face, keyway on the driving lever other end on intrinsic key and the A page or leaf lower end crimping forms and is slidingly matched, with have keyway on the B page or leaf crimping that A page or leaf lower end crimping is connected, rotating lever can make key insert in A page or leaf and the B page key groove and locate.

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

Fig. 1, structure principle chart of the present utility model;

Fig. 2, A-A sectional drawing of the present utility model.

This hinge and ready-made hinge are installed equally, and a fan window page or leaf only needs one pair of ready-made hinge and one pair of windproof Positioning hinge, below windproof Positioning hinge generally is installed in.Promote the window page or leaf, as shown in Figure 1 and Figure 2, the keyway 3 and 3 on two pages of hinge A, B ' on time because the driving lever upper end is contained in spring 4 effects of nut 5 and A hinge crimping side, key 2 promptly spring into keyway 3 and 3 ' in, the pinning hinge.When closing window, with finger pull driving lever 1, key 2 withdraw from keyway 3 ', can close window after rotating the A page or leaf.

Generally speaking, two in the keyway 3 on the B page or leaf Rolldown hem ' have at least is selected the gears keyway 3 of two diverse locations (promptly have ') promptly angle commonly used and one is similar to 180 ° of angles.

The utility model is compared the useful effect that has with background technology: adopt key to spring in the keyway, connect reliable, wind-proof performance is good, can drive two or two keyways with different angles at B page or leaf Rolldown hem as required, can reach corresponding opening angle, obviously superior than adopting catch not have the shelves of selection. It is simple in structure in addition, cost is low, easy to use, can timber structure or cement structure the door or window use.
