Description

The sliding sash latch

The utility model relates to a kind of latch, particularly a kind of sliding sash latch.

Existing sliding sash latch generally is to be made of lock body, switch and latch hook, these latch complex structures, and the manufacturing cost height in the installation process, must be opened a bar shaped slotted hole on sash, and the bar shaped slotted hole makes the installation of latch very inconvenient because of processing is not easy standard; During use, the user can only adopt manual mode by latch that sash lock is tight; After using a period of time, latch damages easily because of the frequent collision of sliding window sash; Another deficiency of this class latch is that theftproof performance is poor, as long as have human sheet or sharp shaped material to insert in the window frame latch hook is pushed aside, just latch can be opened.

The purpose of this utility model provide a kind of simple in structure, cost is low, easy for installation and sliding sash latch that theftproof performance is strong.

The purpose of this utility model is to realize by such technical scheme, it includes the lock body and the latch hook of band fixing hole, it is characterized in that: be provided with dead bolt and help the latch hook that changes part to be placed in the boss of lock body and be hinged, the system that system commentaries on classics sliding axle on the pintle hook lock passes on the boss is changeed pilot hole, and be connected with lock body by the pintle hook lock resetting means, the end that system is changeed sliding axle is provided with press button, the locking Ka Tai that locking plate intrinsic and on the pintle hook lock matches on the latch hook is provided with the latch hook resetting means between latch hook and the lock body.

When the utility model is installed, need only on the smooth rabbet of sash, open the circular hole of the latch hook of being convenient to pack into, just can the utility model be contained on the smooth rabbet of sash easily, and be fixed by fixing hole with screw.During use, sash need only be pushed to be equipped with on the frame of snap close, help the commentaries on classics part on the snap close edge collision latch hook, dead bolt inserted snap close when latch hook was rotated, under the effect of pintle hook lock resetting means, the locking plate of pintle hook lock cooperatively interacts with locking Ka Tai and blocks latch hook, and sliding sash is automatically locked.At this moment, latch hook is blocked by the locking plate of pintle hook lock, and it can not turn round because of stirring of other object, and latch can not be opened, thereby has strengthened theftproof performance.In the time of need windowing, need only press press button, make the system rotating shaft of sliding change pilot hole and slide along system, break away from latch hook until the locking plate of pintle hook lock, latch hook makes dead bolt break away from snap close under the effect of latch hook resetting means and turn round, promote or the pulling sliding sash, can open sash easily.

Owing to adopted technique scheme, the utlity model has simple in structure, handling ease, low cost of manufacture, advantage such as easy for installation and not fragile, it need only promote sliding sash just can be with the window automatic blocking, very easy to use, has very strong theftproof performance.
