Description

Window lock positioning device

The invention relates to a window lock positioning device, in particular to a buckle positioning device specially designed for push-open or swing-open window installation.

Generally, the push-open or the swing-opening window (Casement) is provided with a lock Latch for rotation opening and locking, as shown in Figures 9 to 11, the basic structure is a locking device. The base (1) is provided with a rotating snap member (2), and the rotating shaft is used to drive the rotating shaft of the rotating latching member, so that the oblique tongue piece (22) of the rotating latching member is buckled on the window frame body. The fasteners are locked and unlocked.

In the early days, the above window locking device has the disadvantage that the rotating snap member does not have any tension when it is rotated, and even if it is used for a period of time, it is easy to be loose or stuck, and the rotating snap member is rotated to the position of the buckle or the original original is restored. At the time of the point, there is no positioning feedback or confirmation response.

In addition, the conventional window locking device has a rotating snap member (2) that is easily lowered by gravity due to the locked state, so that it loses the locking function.

Recently, in response to the above-mentioned positioning confirmation problem, successive practitioners have proposed the relevant overcoming technology, and the TW M399895 positioning hinge structure patent case is provided with a spring piece on the side of the rotating shaft and against the rotating shaft, by rotating the cutting surface on the outer circumference of the shaft, Make a spin When the rotating shaft is rotated to the positioning, the positioning confirmation function is achieved; and if the inventor has previously applied for a patent application, the Republic of China Patent No. 104113252, the Chinese No. 2015102223553.8, and the US Patent No. 14/726,705, etc., are enhanced by the shrapnel against the rotating shaft. Tension and positioning confirmation effect.

The inventor believes that the above-mentioned positioning method of the elastic piece against the rotating shaft has obvious disadvantages, such as the elastic piece being easily broken, unable to make proper tension adjustment, and the like.

In view of the absence of a general window locking device, the inventors have developed the invention of a "window lock positioning device".

The technical core of the window lock positioning device of the present invention is that the base side corresponds to the circular shaft of the rotating snap member, and is provided with a perforated hole and a steel ball, a spring ring and a screw-in adjustment screw are built in the hole, and the rotation is further performed. The outer circumference of the circular shaft of the fastening component is provided with a corresponding circular arc groove, and the steel ball is pressed against the outer circumference of the circular shaft of the corresponding rotating fastening component, so that the rotating fastening component rotates to the buckle or unlock the positioning, the steel ball Insert the arc groove to create a positioning effect.

The window lock positioning device of the present invention is characterized in that the adjusting screw has the flexibility of directly adjusting the steel ball against the outer circumference of the circular shaft of the rotary snap member and the circular arc groove, thereby providing more practical use and Convenience.
