Abstract

The utility model provides a door or window lock, which comprises a bottom plate and a side plate connected with the bottom plate. One end of spiral spring is arranged on the inner side of the bottom plate, and a baffle is supported by the other end of the spiral spring. A rotary shaft of a handle is supported by the side plate. The rotary shaft is provided with an eccentric wheel. The eccentric wheel is arranged inside a space between two side plates. The eccentric wheel is contacting and matching with one side of the baffle. The other side of the baffle is provided with a latching pin crossed with the baffle. One end of the latching pin is fixedly connected with the baffle. A free end of the latching pin can pass through a through hole positioned on the bottom plate under the pushing of the eccentric wheel, and is outwardly extended towards the outer surface of the bottom plate, or the free end of the latching pin can retract inside the outer surface of the bottom plate under the condition of the baffle pushed by the spring. The baffle and the latching pin are together moved along the direction of the extension or retraction.

Description

The door and window lock

Technical field

The utility model relates to a kind of door and window lock, particularly with bar and doorframe and window frame device fixed with each other.

Background technology

In the prior art, drive dead bolt by handle for doors and windows usually, bar and doorframe and window frame is fixed with each other.Because the interlock of handle for doors and windows and dead bolt, usually when door and window, must the rotary door window handle.When expectation lock door sash, often need to drive another locking mechanism, for example knob or by latch mechanism key operated or that close.Therefore this latch mechanism need further improve.

The utility model content

At the technical problem that exists in the prior art, the utility model provides a kind of door and window lock, and it comprises base plate, the side plate that links to each other with base plate.Helical spring one sits up straight the inboard of dropping on base plate.The described helical spring other end is supporting baffle plate.The turning cylinder of handle is supported on the side plate.On described turning cylinder, be provided with eccentric wheel, in the space of described eccentric wheel between two side plates.One side contacts of described eccentric wheel and baffle plate cooperates.Have latch with the baffle plate quadrature at the opposite side of described baffle plate, an end of described latch is fixedlyed connected with baffle plate.The free end of described latch can pass from the perforation that is arranged in base plate under eccentric impetus, stretches out beyond the external surface of base plate, perhaps promotes under the effect of baffle plate the free end of latch to be withdrawn in the external surface of base plate at spring.Described baffle plate and latch are together along stretching out or the direction of shrinking back moves.

Provide in the another kind of door and window lock at the utility model, on described base plate, be provided with two columns at interval that are parallel to each other, on each column, have the adjacent of the helical spring of suit at described column, have by fixture and be fixed on lock core on the described base plate, be provided with lock bolt in the described lock core, having dead bolt with the lock bolt quadrature in a side of described lock bolt, is key hole at the opposite side of described lock bolt.At blocking, dead bolt extends to beyond the plane at external surface place of base plate.At unlocking condition, described dead bolt is positioned in the plane at external surface place of base plate.

Provide in the another kind of door and window lock at the utility model, have flange at the free end of described column, described flange constitutes the stopping means of baffle plate, and the cylinder of column is fixed on the base plate.Baffle plate is slidingly matched by the cylinder of through hole and column.

Provide in the another kind of door and window lock at the utility model, be provided with sleeve near described perforation, described sleeve is fixed on the inboard of base plate, and described latch is movably located in the hole of sleeve.

Provide in the another kind of door and window lock at the utility model, described handle is colyliform handle or shaft-like handle.

Provide in the another kind of door and window lock at the utility model, on described base plate, be provided with fixing hole

Provide in the another kind of door and window lock at the utility model, in described fixture, have the screw that makes the lock core location.

Employing the utility model has the advantages that, driving eccentric wheel by rotary handle rotates, make latch insert in the obturator hernia of doorframe and window frame, when latch enters final locked position of coupler, the axis of latch passes the center and the eccentric center of the cross section of handle axis of rotation, therefore eccentric wheel is in self-locking state, and under the situation of turning handle not, latch can not be return from extended position.

Owing to also be provided with lock bolt and dead bolt with key actuated, therefore under unauthorized situation, random door and window.
