Description

Slide window lock

The utility model is a kind of slide window lock, belongs to building accessory field.

Can make the locking device of sliding sash locking and unlatching have many reports, some is come into operation, and left and right sides automatic blocking device and manually middle locking device two big classes are wherein arranged.Because locking device only with a lock, has been saved a lock than left and right sides automatic blocking device, so be widely used on the sliding sash for a secondary window manually.But, manually in the middle of locking device because the scarce limit of himself structure, make and window or closing window all must use the hand motion locking device that this has just brought inconvenience and unsafe factor.

The purpose of this utility model is the middle automatic blocking device that provides a kind of sliding sash to use to make a secondary window only use a lock, and automatic blocking and need not manual locking when closing window, and is safe and reliable, easy to use, manufactures simple.

The purpose of this utility model is achieved by the following technical solution:

Form slide window lock by lock body (1), dead bolt (2), torsion spring (4), snap close (6), wherein, lock body (1) middle part is dead slot (18), dead bolt (2) and torsion spring (4) are housed in the dead slot (18), the front end of dead bolt (2) has inclined-plane (20), the rear portion is handle (22), there is dead slot (12) at the middle part, one end of torsion spring (4) props up the bottom of lock body (1), the other end compresses the front end of dead slot (12) and dead bolt (2) front end is stretched out outside the lock body (1), and cavity (21) and corresponding with the front end of dead bolt (2) is arranged on the snap close (6).

In the such scheme, torsion spring (4) puts hinge (7), be placed in the bottom groove (8) of dead slot (18) at lock body (1) middle part, seal the two ends of hinge (7) with pressing plate (5), respectively that pressing plate (5) is fastening with the riveted joint of screw (11) or expanding by a hole (10) at hole (9) on the pressing plate (5) and groove (8) two ends, and torsion spring (4) is fixed in the lock body (1); Dead bolt (2) is placed in the dead slot (18) of lock body (1), the front end on dead bolt (2) band inclined-plane (20) can be in the inside and outside motion of lock body (1), there is dead slot (12) at the middle part of dead bolt (2), one end of torsion spring (4) props up the bottom of lock body (1), the other end compresses the front end of dead slot (12) and dead bolt (2) front end is stretched out outside the lock body (1), the rear portion of dead bolt (2) is handle (22), is used to make in dead bolt (2) the front end withdrawal lock body (1); By the silk hole (16) on hole (15) on the cover plate (3) and the lock body (1) cover plate (3) is fastened on lock body (1) with screw (17) or expanding riveted joint and goes up and seal lock body (1); Cavity (21) and corresponding with the front end of dead bolt (2) is arranged on the snap close (6).

The available extension spring of torsion spring (4), top spring, tension spring and other flexible member replace.

1 or 2 positive stop lug boss (13) also can be set in the dead slot (18) of lock body (1), 1 or 2 dead slots (14) matching with positive stop lug boss (13) can be set, on the dead bolt (2) with the front and back scope of activities of further qualification dead bolt (2).

The end that snap close (6) is gone up with dead bolt (2) front end inclined-plane (20) is touched mutually can be made into inclined-plane (19).

By installing hole (23) on the lock body (1) and the installing hole (24) on the snap close (6) lock body (1) and snap close (6) are installed on respectively on the two fan windows, and move with window.

When closing window, along with the move toward one another of two fan windows, the inclined-plane (20) of the front end of snap close (6) and dead bolt (2) front end collides, and makes the front end withdrawal lock body (1) of dead bolt (2).When making dead bolt (2) front end aim at the cavity (21) of snap close (6) when window continuation motion, dead bolt (2) is protracted by torsion spring (4) promotion and resets, and then pins sliding sash automatically.

When windowing, pull handle (22) makes dead bolt (2) retraction, until the front end disengaging snap close (6) of dead bolt (2), and then realizes unblanking, windowing action.Finish window after, unclamp handle (22), dead bolt (2) protracts under the effect of torsion spring (4) and resets.

The utility model is used for the middle automatic blocking of sliding sash, can make a secondary window only use a lock, but and automatic blocking and need not manually when closing window, easy to operate, safe and reliable, simple and reasonable, be easy to produce.

Be described in further detail the utility model below in conjunction with accompanying drawing, but the utility model is not limited to the accompanying drawing illustrated embodiment.
