Safety lock for door and window

The utility model belongs to a kind of insurance latch that is used in slide door or window.

In existing known technology, the slide door or window latch of selling on the market does not all have insurance institution.Look into Chinese patent 92207228.0 " door and window push-and-pull safety lock ", adopt cam insurance institution, but structure also is not very simple, more loaded down with trivial details, part is many in addition.

The purpose of this utility model provides a kind of simple in structure, only with the door and window push-and-pull safety lock of the door and window mechanism of a rocking bar insurance institution.

The purpose of this utility model is achieved by the following technical solution, it comprises lock body, lock core, return spring, latch hook and fastener, between described lock body and described lock core, be provided with the insurance rocking bar, the stage casing of this insurance rocking bar is connected for axis hole mechanism with lock body, can shake, one of this insurance rocking bar is tommy bar, be arranged in the pit that lock body is outwards offered, the other end is dogging (10), between lock body and lock core, salient point (8) coupling that the groove hook of the top of this dogging and side direction and described lock core (3) are provided with, described top and groove dogging are lived this salient point (8) makes lock core (3) be in long closing or normally open position.

At the dogging of one of above-mentioned insurance rocking bar and lock body is contacted is provided with positioning convex point on facing the wall and meditating, be provided with detent on the corresponding surface on the described lock body, dark concave point is also established in two of groove and stage casing, and this positioning convex point moves in detent.

The above-mentioned insurance rocking bar and the axis hole mechanism of lock body can be by various ways: can be to establish axle on the insurance rocking bar, establish the hole on the lock body; Also can on the insurance rocking bar, establish the hole, establish axle on the lock body; Reach modes such as adopting articulated structure.A kind of concrete form of this axis hole mechanism is, the stage casing of insurance rocking bar is an axis of rocking, offers the hole on the lock body, and this hole is opened in the ladder junction that underside wall and pit are faced the wall and meditated, this hole half on underside wall, second half is on pit is faced the wall and meditated.

The course of work of the present utility model is such, lock body partly and fastener be contained in corresponding two limits of doorframe and window frame (lock body outwards offer pit expose outside) respectively, hand is pulled tommy bar and is rotated dogging, and dogging is thrown off on one side, this lock with do not insure not the same.If hand is pulled tommy bar and rotated dogging and make the top of dogging withstand salient point on the lock core, or make the groove hook of dogging hook salient point on the lock core, lock core can not move on lock body, promptly is in to grow to close or normally open position, has realized insurance purpose.(the length is here closed or long opening, by the return spring between lock body and lock core specifically by put the position coming fixed).Sliding door (window), latch hook and lock machine collision on the lock body, length of spring compressed, the pinning that interlocks of latch hook and snap close.

The utility model adopts simple endplay device to solve the insurance problem, and part is few in addition, and structure is ingenious, compares with original insurance institution, and what cost obviously will be low is many.

If set the position salient point on dogging, lock body is established corresponding detent, and the insurance rocking bar is in rotation, and positioning convex point moves in detent, and can make the insurance rocking bar keep stable when stopping, anti-sliding stop two and three dark concave points location, stage casing.

If adopt above-mentioned axis hole mechanism, insurance rocking bar stage casing is an axle, and the hole is located at the ladder junction of lock body bottom surface and pit, makes the more compact structure of lock, and this hole is an axis hole, be again the hole of passing through for tommy bar, and assembling is also quite convenient.
