Description
The utility model relates to a kind of lock for sliding door and window.
Chinese patent ZL94210933.3 utility model discloses a kind of automatic window catch.It is made up of holder and fasteners, and its primary structure is the movable hook that sways under the torque spring effect, and movable hook is bearing in by axle in the dead slot of holder, and this structure can combine the action of windowing and unblanking, and finishes with same active force.But it exists in actual production installs difficulty, the shortcoming that production efficiency is low.Mainly be because axle will pass 6 axis holes on holder, torque spring and the movable hook respectively.To overcome the bounce raise positive position of torque spring with hand on one side during installation, Yi Bian wear axle, careless a little, will be stabbed wound finger by spring, speed of production is slow.Moreover this structure makes movable hook rotate difficulty after having an oxidation and rusting in actual use, even rust extremely can not rotate.
I have overcome above-mentioned shortcoming through improvement on this basis, design a kind of simple in structure, assembling easily, a kind of lock for sliding door and window of safety durable, and applied for patent, number of patent application is 98245729.4.This sash lock in use can make " opening " or " pass " window only just finish with an action equally.Though this technology has solved ZL94210933.3 number shortcoming, also has structure and complex manufacturing, make cost of production and original close, the market advantage fails to display.
The utility model is the improvement again to 98245729.4 number of patent applications.Its objective is for further simplified structure and production technology, reduce production costs, reach the competitive advantage on the market.
The utility model is achieved in that a kind of lock for sliding door and window, handgrip and latch hook fuse and are the L type, latch hook stretches out from the dead slot of lock body frame, the gib head of front end matches with stay hook, be respectively equipped with the spring location on the position corresponding with the lock body frame, latch hook two ends, back-moving spring is fixed on both spring location.
Handgrip of the present utility model and latch hook fuse, and are fulcrum with lock body frame and base plate interface point, and handle is scratched with fulcrum when the active force plate of being windowed is moving, and the gib head disengaging stay hook of latch hook and suitable power are opened window.Back-moving spring changes torque spring for the folder spring, and latch hook two ends and lock body frame are clipped.The utility model has been saved rotating shaft, has used the folder spring instead, the willow of original lock body frame and base plate is connect make integral die-cast into, thereby simplify the structure and production technology, lock body frame and base plate integral die-cast can will be omitted in the middle of the base plate, only use two ends, saved material, reduced cost of production.Thereby reduced the price of product, strengthened competitiveness of product.
Further specify the utility model below in conjunction with accompanying drawing:
Fig. 1 is a front view of the present utility model;
Fig. 2 is the rear elevation of Fig. 1;
Fig. 3 is the left view of Fig. 1;
Fig. 4 is the local enlarged diagram of Fig. 1;
Fig. 5 is the rear elevation of another embodiment of the present utility model;
Fig. 6 is the local enlarged diagram of Fig. 5.
As Fig. 1~shown in Figure 4, the utility model lock for sliding door and window, its handgrip 1 fuses with latch hook 6 and is the L type, latch hook 6 stretches out from the dead slot of lock body frame 2, and the gib head 7 of front end matches with stay hook 4, and latch hook 6 two ends and lock body frame 2 are respectively equipped with spring location 3 on the corresponding position, spring location 3 is a pit shape, back-moving spring 5 is circles of opening, and openend is fixed in both pits of spring location 3, and the order folder spring 5 that resets is fixed on this position and can not drops.
Embodiment two, as Fig. 5~shown in Figure 6, the present embodiment lock for sliding door and window, its structure and embodiment one are basic identical, and difference is that spring location 3 is a projection shape, back-moving spring 5 is extension springs, circle between the every circle of extension spring is apart from being close to 0, and back-moving spring 5 is enclosed within on both projections of spring location 3, and making back-moving spring 5 be fixed on this position can not drop.
