Abstract

The utility model relates to a lock for aluminium alloy doors and windows. Swivel hooks of the existing rotary locks for the aluminium alloy doors and windows are generally arranged at the outer side of a lock casing, and beautiful appearance is affected. A moveable swivel hook of the utility model is fixed to one end of a rotary shaft positioned in the lock casing on which a hook outlet hole is formed, and the moveable swivel hook is connected with a positioning flexible assembly which has the functions of stabilizing the moveable swivel hook at an opening position and a closing position. The structure enables the moveable swivel hook and a fixed hook to be arranged at positions which are out of sight, and thus, the beautiful appearance of the doors and windows is not affected. The positioning flexible assembly of the further technical scheme of the utility model is a tension spring which is hung on the excentric part of the moveable swivel hook. The structure can have larger torque to enhance the restoration and stabilizing force of the moveable swivel hook.

Description

Aluminium alloy door's sash lock

The utility model belongs to a kind of aluminium alloy door sash lock.

Aluminium alloy door's sash lock all has a movable hook, movable hook has pressing, rotary type is arranged, existing rotary type movable hook majority is provided in a side of outside the lock housing, influence attractive in appearance, and this class lock to be used for the stable location elastomeric element of opening and close two positions be to adopt to be located at two flexure strips clamping rotating shaft in the lock housing, the stability force that resets is strong inadequately.

The utility model aims to provide a kind of rotary type movable hook and is located in the lock housing, can make stay hook and movable hook all not be exposed at aluminium alloy door's sash lock at the visible position of sight line.

Further purpose of the present utility model provides the strong above-mentioned aluminium alloy door sash lock of a kind of stability force that resets that can make movable hook open and close two positions.

The technical scheme that realizes above-mentioned purpose is: the utility model comprises stay hook (10), lock housing (4), pass the rotating shaft (2) of lock housing, be fixed on the handle (1) in the rotating shaft and rotate after can tangle the movable swivel hook (5) of stay hook (10), it is characterized in that: described handle (1) is fixed on rotating shaft (2) and is positioned at the outer end of lock housing, movable swivel hook (5) is fixed on the end that rotating shaft is positioned at lock housing, movable swivel hook with it is stable at out, the location elastomeric element (7) that closes two positions links to each other, and lock housing is provided with and can makes movable swivel hook produce lock housing to go out dog hole (9) with what hook stay hook.

Further scheme of the present utility model is: the location elastomeric element (7) that described and movable swivel hook links to each other is an extension spring, and extension spring one end hangs on the reference column (11) in the lock housing, and the other end hangs on the eccentric position of movable swivel hook.

Operating principle of the present utility model is: when this lock is in out state, movable swivel hook is positioned at (referring to Fig. 3) in the lock housing, and the elastomeric element that is positioned (7) is stable at this position, rotate the outer handle of lock housing, the movable swivel hook that is positioned at lock housing overcomes the elastic force of locating elastomeric element and produces by the dog hole that goes out on the lock housing, hook stay hook, and the elastomeric element that is positioned again is stable at this position (referring to Fig. 4).

The location elastomeric element that further scheme is provided is extension spring, when lock is in out state, movable swivel hook coupler body is positioned at lock housing, and is hung in extension spring on its eccentric position and is stable at and should " opens " position, the rotation handle, movable swivel hook coupler body produces lock housing, hook stay hook, in the rotation process, the extension spring elongation, after turning over the summit, movable swivel hook is stable at " pass " attitude position again by extension spring.

The utility model is hidden in lock housing with movable swivel hook, and this structure can also be located at the position that sight line be can't see on the door and window with stay hook, so do not destroy the attractive in appearance of door and window.

The location elastomeric element of the further scheme of the utility model is the extension spring of pulling activity swivel hook eccentric position, and this structure can have bigger torque, so can make movable swivel hook that the stronger switch stability force that resets is arranged.
