Description

The light lock of slide door or window

The utility model relates to a kind of lock, especially a kind of lock for sliding door and window.

China utility application 92230386.X discloses a kind of slide window lock, and this slide window lock is made up of lock body and snap close, and lock body is provided with L shaped flank, has U-shaped snap close stopper slot on the flank.Because the movable part of its lock body adopts slide block structure, structure is comparatively complicated, thus the defective of existing.

It is comparatively simple that the purpose of this utility model provides a kind of structure, and the light lock of slide door or window easy to use.

The light lockset of slide door or window of the present utility model has lock body and snap close, offers the snap close installing hole on snap close, and lock body is made of lock body frame, clamp, handle, cover plate and elastic reset spare.Wherein, cover plate is fixed in lock body frame front end, has opening and lock body installing hole on the cover plate.Clamp is arranged at lock body frame rear end, offers the hook hole on the clamp.Have gib head at the snap close front end, this gib head matches with the hook hole on the clamp.Handle is fixedly connected as handle with clamp--clamp association, and the end of handle extends near the cover plate opening, handle--and clamp association and lock body frame are hinged through articulated elements.Have position limiting structure on the lock body frame, elastic reset spare is positioned at handle--and between clamp association and the lock body frame, the elastic force that elastic reset spare applies makes handle--and clamp association relies on the position limiting structure on the described lock body frame.In the utility model, with handle--the articulated elements that clamp association hinge is tied on the lock body frame can be hinging pin shaft, hinge etc.Elastic reset spare can be top spring or extension spring, ring spring, torsion spring, reed etc.Position limiting structure on the lock body frame can be projection or platform, and its effect is to make clamp under the resilient force of elastic reset spare, is in and can keeps good fit position with snap close.When using light lock of the present utility model, can utilize the installing hole on cover plate and the snap close that lock body and snap close are individually fixed on the fan body and framework of slide door or window, and the gib head of snap close front end is in and the clamp state (this moment, door and window was locking states) that hanging hole matches of rising to the bait.When the need door and window, hand is extended the cover plate opening part, when stirring handle, the bar body is imposed lateral force.In stirring the process of handle, handle--clamp association rotates around the hinge of articulated elements, clamp hook hole release lock clasp head and lock is opened.Because this moment, the door and window fan body was subjected to lateral force, so the respective transversal slip, thereby the opening of doors and windows process finished.After unlatching was finished, handle--clamp association can realize resetting under the effect of elastic reset spare.

The light lock of slide door or window of the present utility model compared with the aforementioned existing similar products, its structure is comparatively simple, and can be when unblanking door and window, promptly unblank and the action of door window is once finished, thereby make operation more easy.In addition, no matter this lock is used for the left side or the right side of door and window, its structure is all identical, owing to have this advantage, makes it both be convenient to make, and is convenient to again install.

Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.

Fig. 1 is the structural representation of the light lock of slide door or window among the embodiment.

Fig. 2 and Fig. 3 are schematic perspective views.

Shown in Fig. 1～3, the lock body that the light lockset of the slide door or window in the present embodiment has snap close 1 and is made of lock body frame 2, clamp 3, handle 4, cover plate 5 and elastic reset spare 6.On snap close 1, offer snap close installing hole 7.Cover plate 5 is fixed in the front end of lock body frame 2, has opening 8 and lock body installing hole 9 on the cover plate.Clamp 3 is arranged at the rear end of lock body frame 2, offers hook hole 10 on the clamp.Front end at snap close 1 has gib head 11, and this gib head matches with the hook hole 10 on the clamp.Handle 4 is fixedly connected as handle with clamp 3--clamp association, and the end of handle 4 extends near the opening 8 of cover plate, and handle--clamp association and lock body frame 2 are hinged through articulated elements 12.Have position limiting structure 13 on the lock body frame 2, elastic reset spare 6 is positioned at handle--and between clamp association and the lock body frame, the elastic force that elastic reset spare 6 applies makes handle--and clamp association relies on the position limiting structure 13 on the lock body frame.In the present embodiment, elastic reset spare 6 adopts elastic spring, and articulated elements 12 adopts swivel pin, and lock body frame position limiting structure 13 adopts the boss form.

When using the light lock of this enforcement in executing, can utilize 9,7 installing holes that lock body and snap close are individually fixed on the fan body and framework of slide door or window, and allow snap close gib head 11 be in and the clamp state that hanging hole 10 matches of rising to the bait.When the needs door and window, hand can be extended the horizontal application of force in cover plate opening 8 places.In horizontal application of force process, handle 4 and cover plate 5 will be simultaneously stressed.Handle--clamp association serves as that axle rotates because of handle is stressed with swivel pin 12, and clamp 3 flips an angle, and causes clamp hook hole 10 releasable catch gib heads 11, and lock is opened.Meanwhile, the lateral force that cover plate 5 is subjected to passes to the slide door or window fan body, and the door and window fan body is opened the back respective transversal at lock and slided, thereby finishes the opening of doors and windows process.After the lock unlatching was finished, handle--clamp association realized resetting under the effect of elastic reset spare 6.When closing the doors and windows, the door and window fan body can be pushed into fastening position, the front end of the front end compressing clamp 3 of gib head 11, clamp serves as axle deflection with swivel pin 12, makes gib head 11 slip into clamp hook hole 10, under the effect of elastic reset spare 6, clamp 3 resets, and with the gib head locking, that is finishes the locking process.
