Abstract

The utility model relates to a self-locking handle, which is composed of handles and a self-locking mechanism. The self-locking mechanism is composed of brackets, a lock piece, a rotary shaft, a torsion spring, etc. The handles are installed on the brackets, and the lock piece which is provided with a cam curved surface and the torsion spring are arranged on the middle of two brackets; shielding iron is arranged on one side frame; when a door or a window is closed, the door or the window can be locked automatically by the cam curved surface, the torsion force of the spring and the shielding. The utility model has the advantages of simple structure and strong practicability; the utility model can prevent the door or the window from being flapped repeatedly under the action of the wind, and locking devices such as bolts, etc. can be omitted.

Description

Self-locking handle

The utility model relates to a kind of door-window kind handle with auto-lock function.

Traditional handle general utility functions are single, a handgrip in the time of can only being folding.Except that handle is installed, one group of latch must be adorned on the common door and window, the locking when door and window is closed could be realized.The steel sash for building that development in recent years is got up is installed a kind of handle handle, after closing sash, rotates handle, can realize the locking of window, but need manually-operated, can not realize self-locking.

The purpose of this utility model provides a kind of when door and window is closed, and adds action without any need for negative, just can realize the locking of door and window.

The utility model is achieved in that

This Self-locking handle comprises handle and self-locking mechanism, its self-locking mechanism is made up of support, locking plate, rotating shaft and torsionspring etc., handle is fixed on the moving fan of door and window by support, in the middle of the two stands rotating shaft is housed, locking plate and spring are contained in the rotating shaft, an end of its torsionspring is pressed on the locking plate, the other end leans against on the handle, locking plate is subjected to the effect of spring force under free state, can change a low-angle.The opposite side of locking plate axis hole, curved curved surface, this curved surface and rotating shaft constitute the cam swing mechanism, and when bar was closed, locking plate with the locking plate locking, made the fan must not activity under the buting iron on torsionspring and the frame (also can be edge) double action.During door and window, the handle of trip lock sheet afterbody is to overcome the resistance of spring, and locking plate rotates, and the cam curved surface part of locking plate is broken away from buting iron, can the door and window fan.

Different installation because of common door sash and framework, generally exceptionally pushing-type and interior pull-type two kinds of opening ways, the utility model also should have two kinds of different form of structure mutually, its main distinction: outer pushing-type locking plate shaft hole is above cam curved surface, with jamb is buting iron (or adorning a buting iron on frame), and this buting iron and cam curved surface interact and finish automatically locking of door and window.During unlatching, the locking plate handle is upwards pulled, can freely be opened after making curved surface break away from buting iron.

Interior pull-type door and window locking plate shaft hole is adorned a Z-shaped buting iron on jamb below cam curved surface, match with cam curved surface and finish automatically locking of door and window.During unlatching, the locking plate handle is pulled downwards, curved surface and buting iron are thrown off just can freely open.

The utility model has been realized the automatic blocking when door and window is closed by the cam self-locking mechanism is combined with the ingenious of handle, and is simple in structure, practical.Solve the problem that door and window that people usually run into is patted repeatedly because of the wind-force effect preferably, saved bolt mechanism.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is outer pushing-type door and window Self-locking handle front view:

Fig. 2 is outer pushing-type door and window Self-locking handle right view;

Fig. 3 is interior pull-type door and window Self-locking handle front view;

In Fig. 1,2, on the bar fixedly two stands 3 handles 1 be contained on the support, adorn a rotating shaft 6 in the centre of support 3, in rotating shaft 5, adorn a locking plate 2 and torsionspring 4, the two ends of spring 4 lean against respectively on the handle and locking plate on, under free state, locking plate turns a little angle under the effect of spring force.The curved surface of locking plate axis hole opposite side is the work plane when being used for self-locking, form cam curved surface with rotating shaft, when closing the doors and windows, cam curved surface at first be contained in jamb on buting iron (or edge itself) contact, and locking plate is swung, so that locking plate under the acting in conjunction of spring and buting iron, makes the locking plate locking, moving fan can not freely be opened.When opening, the handle 6 of trip lock sheet afterbody makes the locking plate curved surface throw off buting iron, just can free door and window.

Fig. 3 is the handle self-locking mechanism of interior pull-type door and window, compares with the Self-locking handle of outer pushing-type door and window, is characterized in the locking plate axis hole below cam curved surface, and adorns a Z-shaped buting iron on doorframe and window frame, matches with cam curved surface and finishes the auto-lock function of door and window.During unlatching, the handle 6 of locking plate afterbody is depressed, curved surface and buting iron are thrown off, can freely open.

Claims

1, a kind of Self-locking handle, comprise handle and self-locking mechanism, it is characterized in that self-locking mechanism is made up of support, locking plate, rotating shaft and torsionspring etc., handle is fixed on the moving fan of door and window by support, in the middle of the two stands rotating shaft is housed, and locking plate and spring are contained in the rotating shaft, one end of its torsionspring is pressed on the locking plate, the other end leans against on the handle, and a cam curved surface is arranged on the locking plate, and buting iron is housed on the jamb.

2, Self-locking handle according to claim 1, it is characterized in that outer pushing-type door and window with the locking plate shaft hole of Self-locking handle above cam curved surface, and available jamb is done buting iron.

3, Self-locking handle according to claim 1, below cam curved surface, the buting iron on the jamb is Z-shaped to pull-type door and window with the locking plate shaft hole of Self-locking handle in it is characterized in that.
