Abstract

The utility model belongs to the technical field of door and window locks, and relates to an aluminium alloy safety door and window lock, which is formed by a lock base, a lock body, a lock hook and a fastening piece, wherein the lock base is fixed on a frame of an aluminium alloy door and window through the fastening piece; the lock body is arranged on the lock base through a pin shaft, and is compressed to be at a ready-to-lock state through a spring; an unlocking handle is integrated with the lock body; and the lock hook is integrated with the aluminium alloy frame. The aluminium alloy safety door and window lock is characterized in that head parts of a lock face on which the lock hook and the lock body are mutually locked are concavely provided with flanges in smooth transition along the directions of opposite locking faces respectively. The aluminium alloy safety door and window lock has a reasonable structure, is safe and reliable, is simple to manufacture, and is applied to push-and-pull aluminium alloy safety door and window locks.

Description

Aluminium alloys safety door sash lock

Technical field:

The utility model belongs to the door-window lockset technical field, relates to a kind of push-pull type aluminium alloys safety door sash lock.

Background technology:

Along with the increase of population, the minimizing of town and country land used, and the raising of Building technology level; The balcony that people live is more and more, and building is increasingly high, and this just requires the weight of building body more gently good more; Aluminum alloy materials has also just become the preferred material of a large amount of building door and window materials naturally, and therefore, the aluminium alloy door sash lock supporting for alumium alloy door and window also just become the important ingredient of decorative craft of building naturally; Yet the greatest problem that present alumium alloy door and window are latched in is: referring to Fig. 1: when alumium alloy door and window be locked in sealed after, particularly in use for some time; Because sealed surface wear and distortion; When the handle of not pressing door and window lock and firmly with alumium alloy door and window 5 during to the direction of opening (directions X) push-and-pull, then 2 pairs of lock bodies 3 of latch hook of closing on the framework 1 of aluminium produce a sensing and directions X opposite effect power F at A point, and this directed force F can resolve into through the rotating shaft 4 of lock body 3 and the component F1 that points to origin of force A and reach the component F2 perpendicular to F1; Component F1 can not make lock body 3 produce and move; Lock body 3 is rotated, and still, component F2 but can make lock body 3 produce 4 rotation around the shaft; Rotate and break away from latch hook 2 and unblank around its rotating shaft 4 when component F2 will make lock body 3 during greater than sealed frictional force, cause potential safety hazard.

The utility model content:

The purpose of the utility model provides a kind of reasonable in design, the safe and reliable aluminium alloy door's sash lock in sealed back, to satisfy people's life requirement.

The utility model is achieved in that aluminium alloys safety door sash lock; Form by lock, lock body, latch hook and securing member; Lock is fixed on the framework of alumium alloy door and window through securing member, and lock body is installed on the lock through bearing pin, and leans on spring that lock body is pressed on the preparation locking state; Unblank handle and lock body is one-body molded; Latch hook and aluminum alloy frame body by integral forming is characterized in that sealed head being mutually locked at latch hook and lock body, and sealed direction to the other side convexes with slick and sly excessive flange respectively.

Above-mentioned latch hook and lock body are mutually locked sealed respectively with itself and its separately the angle of adjacent surface be acute angle, that is to say that the latch hook on latch hook, the lock body is not the right angle, but acute angle.

The utility model is compared the outstanding advantage of prior art:

1, the utility model is safe and reliable: because sealed the head that latch hook and lock body are mutually locked is provided with flange; After latch hook and lock body were mutually locked, hook was held mutually, even if firmly push-and-pull; Aluminium alloys safety door sash lock is unblanked; Have only after pulling the handle of unblanking and unblanking, just can open door and window, safe and reliable.

2, the utility model is made simple; Sealed the head that only need be mutually locked at the latch hook and the lock body of original aluminium alloy door's sash lock is provided with the flange that slick and sly excessive hook is each other held; Only increase cost seldom; Can make aluminium alloy door's sash lock obtain very high security performance, make structure more become reasonable.

The specific embodiment

With specific embodiment the utility model is described further below:

Referring to Fig. 2-5: aluminium alloys safety door sash lock; Form by lock 50, lock body 20, latch hook 101 and securing member; Lock 50 is fixed on the framework 60 of alumium alloy door and window through securing member, and lock body 20 is installed on the lock 50 through bearing pin 30, and leans on spring 40 that lock body 20 is pressed on the preparation locking state; Unblank handle 201 is one-body molded with lock body 20; Latch hook 101 is one-body molded with aluminium alloys framework 10, it is characterized in that sealed head being mutually locked at latch hook 101 and lock body 20, and sealed direction to the other side convexes with slick and sly

excessive flange

1011,202 respectively.

Above-mentioned latch hook 101 and lock body 20 be mutually locked sealed respectively with itself and its separately the angle of adjacent surface be acute angle B1, B2.

The structure stress analysis of the utility model: referring to Fig. 3-5: because the rotating shaft 30 of lock body 20 follows the direction of motion of door and window not parallel with sealed the line with the origin of force of lock body 20 of lock body 20; So; When the handle 201 of not pressing door and window lock, and firmly with alumium alloy door and window 60 when the direction of opening (directions X) push-and-pull, the reaction force P of power on latch hook 101 that is applied on the lock body 20 is broken down into component P1 and P2; Component P2 can make lock body 20 rotate to the direction of unblanking; But because two

flanges

1011,202 of the utility model are held at the D point each other, promptly P2 has offset component P2 at the reaction force P3 that the D point produces; Lock body can not rotated, thereby play the effect of safety door sash lock.

The utility model is identical with the installation and the method for using of common aluminium alloy door's sash lock; Just during fabrication; Sealed the head that only is mutually locked at latch hook 101 and lock body 20; Sealed direction to the other side is provided with slick and sly

excessive flange

1011,202 respectively; And make that latch hook 101 and lock body 20 be mutually locked sealed respectively with its separately included angle B 1, the B2 of adjacent surface be arranged to acute angle, in order to prevent that the component F2 that lock body is rotated from causing lock body to break away from the situation that latch hook unblanks and taking place, make the safety of aluminium alloy door's sash lock and practicality obtain substantial raising exactly.
