(such as: bedroom door, bathroom door, backstairs) it is limited to internal use, antitheft to require without so tight, Ren Menxu What is wanted is the convenience of room door opening and closing.That is indoor door lock is to be in door to be left unlocked or unlatched state, only serves radix saposhnikoviae and blows open Effect, rather than with the real lock function of key.Although the indoor door lock used also needs to use after all often in the state of being left unlocked or unlatched Hand rotating handle or or door knob be just able to achieve door be left unlocked or unlatched closing and unlatching.This is its disadvantage.

Summary of the invention

In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of side hung door locks of narrow fan door and window. Realization can not lock when closing the doors and windows, and door and window is in empty off status, only need to be under door and window void off status when wanting locking door and window Button moves key or knob can be by door and window locking.

The technical scheme adopted by the utility model to solve the technical problem is as follows: providing a kind of casement door lock of narrow fan door and window Body, including shell, lock tongue and reset spring, it is characterised in that: rack gear is installed in the side of lock tongue, has gear on lock core and is somebody's turn to do Rack gear adaptation stops lock tongue mobile, so that lock tongue is in locking states, when rack gear is in the second shape when rack gear is in first state Lock tongue Telescopic movable when state.

Further:

Retaining spring is installed, retaining spring both ends lay steel ball respectively, have circular groove on shell, jointly in the rack gear Form gear rack positioning mechanism.

The lock tongue two sides are symmetrical bicircular arcs inclined-planes.

The beneficial effects of the utility model are: realizing can not lock when closing the doors and windows, door and window is in empty off status, can be with Play the role of radix saposhnikoviae to blow open, can door is left unlocked or unlatched or be opened without with hand；When wanting locking door and window, only shape need to be closed in door and window void Button moves key under state or knob can be by door and window locking.Lock tongue two sides are symmetrical two radiused ramps, facilitate the lock of door and window It closes and opens, pushing or pulling on the door all can open the door or close the door easily；Door latch structure is greatly simplified, the body of lock body is reduced Product reduces the excavating work amount of lock body mounting hole, convenient construction；And there is locking insurance function, it is convenient to lock door and window.
