The utility model relates to a kind of latch, especially a kind of latch that is used for window.

At present, the window latch of selling on the market all needs people with hand latch alignment pins hole could be shut sash mostly, and eyelet is difficult for aiming at, and uses inconvenient.Sometimes forget and close the window that window-glass is easy to damage by dragging, even cause casualty accident.The CN93201491.7 monograph of the applicant application discloses a kind of door and window automatic pinning, but the self-closing doors window, but its spring is exposed, and not attractive in appearance, also damage easily.

The purpose of this utility model is to overcome the existing existing defective of window latch, provides a kind of simple in structure, easy for installation, and cost is low, but the automatic close window family is safe and reliable, good looking appearance, non-damageable window latch.

Task of the present utility model realizes in the following manner: this Automatic hinge pin for window comprises substrate, guide channel plate, spring and flat latch, guide channel plate is fixed on the substrate, the flat latch is contained in the guide channel plate, the abutted surface of flat latch and substrate is provided with spring groove, spring is contained in this spring groove, and substrate is provided with a crimp of stretching in spring groove, and the upper end of spring withstands on the crimp of substrate, the inclined-plane is processed in the lower end of fan-shaped latch, and the below of substrate is provided with hook plate.

The utility model is applicable to the outer latch of opening window, also is useful for the latch of opening window in making.

The utility model is compared with latch with existing window and is had the following advantages: 1. and simple in structure, modern design, manufacturing process is simple, and low cost is easy for installation; 2. be quick on the draw, only need to blow with hand one band or by gentle breeze one gently, window will be closed automatically; Both make things convenient for use, and can protect window and glass not to be damaged again; 3. this casement bolt is safe and reliable, and is durable in use, aesthetic in appearance.Concrete structure of the present utility model is provided by drawings and Examples.

Fig. 1 is structure of the present utility model and scheme of installation;

Fig. 2 is the view in A-A cross section among Fig. 1;

Fig. 3 is the view in B-B cross section among Fig. 2.

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

Embodiment:

With reference to Fig. 1, Fig. 2, Fig. 3, the substrate of this Automatic hinge pin for window (2) is by the steel sheet drawing, substrate (2) is fixed on the sash (1) by wood screw (9), substrate (2) is gone up and is fixed with guide channel plate (3) by rivet (10), flat latch (5) is contained in the guide channel plate (3), fan-shaped latch (5) is processed with spring groove with the abutted surface of substrate (2), spring (4) is contained in this spring groove, substrate (2) is provided with a crimp of stretching in spring groove, the upper end of spring (4) withstands on the crimp on the substrate (2), the inclined-plane of miter angle is processed in the lower end of flat latch (5), and hook plate (6) is fixed on the window frame (8) of substrate (2) below by screw (7).

When sash is subjected to the thrust of P direction, the inclined-plane of flat latch (5) and hook plate (6) are collided, shown in 5 ' position among Fig. 2, because the effect of inertia force, along with the variation of flat latch inclined-plane and hook plate (6) contact position, flat latch (5) rises and compresses spring (4), as among Fig. 25 " the position shown in, when the inclined-plane of flat latch (5) slides to the tip, under the effect of spring (4); flat latch (5) the into hook plate (6) of moving certainly, realize self-locking.Flat latch (5) is slightly upwards mentioned and can be opend the window.
