Description

A kind of push-pull door and window pick-proof lock

The utility model relates to a kind of door and window lock, particularly a kind of being used on the section bar, and the many tongue locks with tamper-resistant function.

At present, though existing lock for sliding door and window is at face shaping, perhaps each is variant on the internal construction, and function of use is all identical substantially, promptly adopts manual pull hook lock, the perhaps automatic latch of spring pull hook, but these locks can only folk prescription to the top or the bottom of pinning door or window, in fact can only play the effect of pin, and, do not possess pick-proof and anti-theft function, when being used in the big sash of highrise building simultaneously, do not have the Wind-Pressure Resistance ability, therefore, do not adapt to the requirement of modern architecture door and window.

The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of safe and reliable, and has many tongue locks of tamper-resistant function and Wind-Pressure Resistance ability.

The technical solution of the utility model is: it is made of lock body, lock core and dead bolt, it is characterized in that lock core is provided with gear, and dead bolt is connected with the tooth bar that is meshed with gear on the lock core.Gear on the lock core is fixed on the lock core outer rim by jump ring, so that during rotational lock core, gear is also rotated thereupon; Tooth bar one end is meshed with gear, and the other end links to each other with dead bolt by connector, and when gear rotated, tooth bar was done toward complex line to move thereupon, also does to move toward complex line thereby drive dead bolt, realizes the unlatching of lock or closes.Dead bolt is made of length-adjustable connecting rod, so that adjust the length of dead bolt according to the size of sash.In addition also be connected with horizontal pull hook on the dead bolt, this pull hook is fixed on the dead bolt by connecting rod, and makes horizontal pull hook rotary extension with dead bolt mobile, is used for fixing another sash.

The utility model compared with prior art has following advantage and extremely long-pending effect: owing to be provided with gear on lock core, and the tooth bar of dead bolt is meshed this gear with being connected down with the tooth bar that is connected upper lock tongue symmetrically, therefore, when opening lock core, gear is rotated, driving two tooth bars simultaneously moves, in the realization, open in the time of following dead bolt or close, on dead bolt, also be provided with horizontal pull hook in addition, when opening or closing dead bolt, make horizontal pull hook also pin another fan window, therefore, it can be multi-faceted pinning door or window, make it to have pick-proof, anti-theft feature, and have the Wind-Pressure Resistance ability, be the modern architecture door, the lockset that window is comparatively desirable.
