Description

Modified aluminium alloy door sash lock

Technical field:

The utility model relates to a kind of door-window lockset technical field, refers in particular to a kind of sliding aluminium alloy door and window lock.

Background technology:

Along with the raising of people's living standard, increasing building constructions adopts plug-type alumium alloy door and window, the important component part that aluminium alloy door's sash lock has also just become the alumium alloy door and window large-scale popularization to use naturally.But because the employing of existing door and window lock is that latch hook and the relative fixed that is fixed on the door-window section bar frame forms lock and the location status of opening at the mutual fastener of the dead bolt of door-window section bar opposite side, unreasonable structure, the contact of dead bolt single-point, long-term inhomogeneous stressed lock body and the latch hook of easily making tilts, the latch hook split is made, complicated, location difficulty is installed, easily relaxes, come off, it is inconvenient to cause aluminium alloy door's sash lock to use.

The utility model content:

The purpose of this utility model provide a kind of rational in infrastructure, install simple, dead bolt is stressed good, the lax novel aluminum alloy door and window lock that comes off of latch hook is to satisfy people's life requirement.

The utility model is achieved in that modified aluminium alloy door sash lock, form by lock 7, lock body 4, latch hook 3, dead bolt 8 and securing member, lock 7 is fixed on the framework of aluminium alloy extrusions by securing member, lock body 4 is installed on the lock 7 by bearing pin 5, unblank handle 1 is one-body molded with lock body 4, and wherein: latch hook 3 and aluminium alloys window frame 2 are one-body molded.

Have a U type hole 9 at the middle part of above-mentioned dead bolt 8.

The outstanding compared to existing technology advantage of the utility model is:

1, latch hook is lax comes off: because latch hook 3 and aluminium alloys window frame 2 are one, thus there is not the lax and obscission generation of the latch hook that causes because of vibrations, discontinuity, durable in use.

2, dead bolt is stressed good: owing to have a U type hole 9 at the middle part of dead bolt 8, make dead bolt become single-point contact (dead bolt, latch hook are difficult to contact in one plane) for multiple spot contacts after locking, stressedly more become reasonable.

3, install simply: because latch hook 3 and aluminium alloys window frame 2 are one, the installation of having saved latch hook when the door and window lock is installed, the orientation problem when also having avoided latch hook to install.

4, structure more becomes reasonable.

Description of drawings

Fig. 1 is an agent structure schematic diagram of the present utility model;

Fig. 2 is the schematic diagram of the utility model lock body.

Wherein: the 1-handle of unblanking, 2-aluminium alloys window frame, 3-latch hook, 4-lock body, 5-axle, 6-torque spring, 7-lock, 8-dead bolt, 9-U shape hole.

The specific embodiment

The utility model is described in further detail with specific embodiment below:

Referring to Fig. 1, Fig. 2: modified aluminium alloy door sash lock, form by lock 7, lock body 4, latch hook 3, dead bolt 4 and securing member, lock 7 is installed on aluminium alloy door's sash, wherein: have a U-shaped hole 9 at the middle part of dead bolt 8, latch hook 3 and aluminium alloys window frame 2 are one-body molded, and the spanner 1 of unblanking is one-body molded with lock body 4, pull when unblanking handle 1 downwards, lock body 4 can rotate around the axle 5 that is installed on the lock 7, forwards certain position dead bolt 8 to and breaks away from latch hook 3, and the fastener state can be unblanked mutually; Loose one's grip when shutting window, 6 of torque springs spring into dead bolt 8 automatically to be realized in the latch hook 3 automatically locking.
