Abstract

A lock for a sliding window belongs to window lock technology field. The aim is to resolve a problem that the lock for the sliding window is closed. The lock is composed of a lock body, a lock core and a lock core draw arm, wherein the lock body is arranged on the lower of an inner fan window frame side face; the lock core passes through the lock body and is vertical to a stepped cylinder of the window, the head section of the lock core faces to window outer and is provided with an inclined surface, the foot section is thinner than the head section; one end of the lock core draw arm is connected with the lock body rotatably, the middle part is movably connected with the caudal end of the lock core, and an offsetting spring is arranged between the lock core and the lock body. Mounted on the lower of the inner fan window frame side face namely the end of the inner fan window lower frame, a lock hole is arranged at a suitable position of the outer fan window lower frame, when closing the window, the lock core is driven to enter the lock hole automatically by the elastic force of the offsetting spring, thus the latch of the sliding window is implemented. When opening the window, so long as drawing the lock core draw arm to draw the lock core head section from the lock hole locating on the lower frame of the outer fan window, so as to release the latch of the sliding window. The integrated intensity of the structure is high, and the lock is not easy to damage. Structure is reasonable, failure rate is low, and operation is very simple.

Description

A kind of slide window lock

Technical field

The utility model relates to a kind of locking device of sliding sash, belongs to the sash lock technical field.

Background technology

At present, in buildings such as industrial premises, office building, residential building, used sliding sash in a large number, the locking device of existing sliding sash generally is made up of the Rotary hanging hook that is fixed in the fixed hook on the exterior wing window frame and be fixed on the interior wing window frame, after two fan windows are pushed to fastening position, also must turn to locked position to Rotary hanging hook, Rotary hanging hook is hung over fixed hook, with the sliding sash locking, operate more loaded down with trivial details; Because this locking device bulk strength is low, often breaks down, reliability is not high.If Rotary hanging hook is gone to locked position under the window open mode, it will produce collision with fixed hook when then closing window, very easily damage.Therefore, traditional sliding sash locking apparatus structure is unreasonable, also has a lot of potential safety hazards, has given thief with opportunity.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of slide window lock simple to operate, long-lived is provided.

Problem described in the utility model realizes with following technical proposals:

A kind of slide window lock is made up of lock body, lock core and lock core torque arm, and described lock body is installed on the bottom of interior wing window frame side; Described lock core is to run through lock body and perpendicular to the stairstepping cylinder of window, and its head is towards outside window and be provided with the inclined-plane, and afterbody is thin than head; One end and the lock body of described lock core torque arm are rotationally connected, and the tail end of middle part and lock core flexibly connects, and between lock core and the lock body back-moving spring is housed.

The utility model is installed in the bottom of interior wing window frame side, i.e. the end of inner fan-window lower frame, and a lockhole is made a call in the appropriate location on exterior wing window lower frame, when closing window, make core lean on the elastic force of back-moving spring to spring into lockhole automatically, just can realize the locking of sliding sash, operate very simple.When windowing, as long as the torque arm of pulling lock core pulling out the lockhole of lock core head from exterior wing window lower frame, can make sliding sash remove locking.Because it is not this structural entity intensity height, thereby fragile.The utility model is rational in infrastructure, and not only fault rate is low, and operation is very simple.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

State when Fig. 3 is the sliding sash locking;

Fig. 4 is the state of sliding sash when opening.

Each label is among the figure: 1, exterior wing window; 2, lock core; 3, lock body; 4, back-moving spring; 5, lock core torque arm; 6, inner fan-window; 7, lockhole.

The specific embodiment

Referring to Fig. 1, there is the stairstepping through hole that is complementary with lock core 2 at the middle part of lock body 3, and lock core 2 can slide along through hole within the specific limits.Lock core 2 is the stairstepping cylinder, and its head is thicker, and afterbody is thinner, and head stretches out from lock body 3 under the effect of back-moving spring 4, and afterbody and lock core torque arm 5 flexibly connect.The lower end of lock core torque arm 5 and lock body 3 are rotationally connected, and the tail end of middle part and lock core 2 flexibly connects, and when spurring the upper end of lock core torque arm 5 to the right, lock core torque arm 5 drives lock core 2 and moves right.

Referring to Fig. 2, on the lock body 3 screw hole is arranged, be used for sash lock is fixed in the bottom of interior wing window frame 6 sides; Lock core 2 afterbodys have a through hole, and the lower end of lock core torque arm 5 is passed the back and linked to each other with lock body 3 from this hole.

Referring to Fig. 3, at the locking states of sliding sash, the head of lock core 2 stretches in the lockhole on the exterior wing window lower frame, and two fan windows are fixed.When windowing, as long as pulling lock core torque arm 5 pulling out the lockhole of lock core head from exterior wing window lower frame, can make sliding sash remove locking.

Claims

1, a kind of slide window lock is characterized in that, it is made up of lock body (3), lock core (2) and lock core torque arm (5), and described lock body (3) is installed on the bottom of interior wing window frame (6) side; Described lock core (2) is for running through lock body (3) and perpendicular to the stairstepping cylinder of window, and its head is towards outside window and be provided with the inclined-plane, and afterbody is thin than head; One end of described lock core torque arm (5) and lock body (3) are rotationally connected, and the tail end of middle part and lock core (2) flexibly connects, and between lock core (2) and the lock body (3) back-moving spring (4) is housed.
