Description

Window latch and door panel latch adjustable mechanism for connecting the length of the rotating shaft

The invention relates to a mechanism for adjusting the length of a rotating shaft of a window latch or a door latch, in particular to a connecting rotating shaft mechanism which can be applied to a lock bar or a lock of different window frames or door panels.

Generally, the window and the door panel are provided with a lock lever and a lock Latch for rotating and unlocking. The basic structure is that a lock lever or a door panel lock for driving the window latch is extended in the rotary handle. The square shape of the tongue piece connects the rotating shaft.

As is known, the thickness of a general window or door panel is not limited to a standard. Generally, the thickness of the window or the door panel is about 25 mm to 60 mm. Therefore, the depth of the latch or the buckle embedded in the window frame is not uniform.

As shown in Fig. 11 and Fig. 12, the conventional window latch is taken as an example. The main structure is a sleeve (2C) with a square hole (21C) under the base (1C) with a screw (SC). Screw into the rotating handle (3C), fix the sleeve (2C) and the rotating handle (3C) to the base (1C) and connect the sleeve (2C) to the rotating handle (3C). One end of the square shaft (4C) is inserted into the square hole (21C) which is open at one end of the sleeve (2C), and the rotary square shaft (4C) is driven via the sleeve (2C) when the rotary handle (3C) is rotated. Lock or unlock.

Therefore, traditionally for the bolts or latches of windows or door panels of different thicknesses, the manufacturer is equipped with a fixed length or a square rotating shaft of different lengths for the manufacture or sale of the latch or the lock. Use, for different thickness of the window or door panel, in addition to the production, inventory and distribution of the difficulty, the square rotating shaft is only installed into the rotating square hole of the latch or the lock structure, it is loose The gap is too large, the noise of the product and the drop of the product.

In view of the general lack of window latches or door panel latches, the inventors of the present invention have developed the "window latch and door latch to adjust the length of the rotating shaft mechanism".

The invention can be applied to different window frames or door panel thickness latches or door panel latches to adjust the length of the rotating shaft, and a curved nut is arranged on the outer edge of the rotating handle, and the inner side of the curved nut is The screw disposed in the inner diameter of the sleeve is fixedly connected, and the other end of the screw is screwed to the longitudinal thread of the square-shaped rotating shaft.

The characteristic is that when the arc nut is rotated, the length of the square-shaped connecting rotating shaft of the tongue block (92A) of the driving window latch or the door latch (9A) can be adjusted, so that the driving rotating shaft mechanism is suitable for Mounting of latches or latches for different window frames or door panel thicknesses.
