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:

By lock body (1), dead bolt (2), handle (3), cover plate (4), spring (5), snap close (6) is formed slide window lock, wherein, the middle part of lock body (1) is boss (10), there are fluting (8) and triangular ramp (9) and fluting (11) in the rear portion of dead bolt (2), dead bolt (2) is stuck on the boss (10), one end of spring (5) withstands on the front end of fluting (8), the other end props up the sidewall (19) of cover plate (4), it is protruding along boss (10) to make spring (5) can promote dead bolt (2), handle (3) slides by matching of its anterior skewback (13) and triangular ramp (9) and drives dead bolt (2) along inwardly contraction of boss (10), spring (7) is housed in the hole (16) on the axis of guide (15) at handle (3) rear portion resets, have cavity (24) corresponding on the snap close (6) with the front end of dead bolt (2) to promote handle (3).

In the such scheme, boss (10) both sides at lock body (1) middle part are groove (12), the fluting (8) at middle part, dead bolt (2) back and the both sides of fluting (11) are the triangular ramps (9) of symmetry projection, fluting (8) is positioned at above the boss (10) and spring (5) is housed, fluting (11) matches with boss (10), triangular ramp (9) is arranged in groove (12) thereby blocks boss (10), dead bolt (2) can be done the linear directional motion along boss (10), dead bolt (2) front end inclined-plane (23) can be stretched out from the fluting (14) of lock body (1) or withdraw, anterior 2 skewbacks (13) of handle (3) are contained in the groove (12) of lock body (1), and the slip that matches with triangular ramp (9) on the dead bolt (2), the axis of guide (15) at handle (3) rear portion is entangled in hole (18) on the guide cylinder (17) on the cover plate (4), and withstand the spring (7) of dress in the hole (16) on the axis of guide (15), the sidewall (19) of cover plate (4) withstands an end of spring (5) and makes its other end withstand the front end that dead bolt (2) is gone up fluting (8), the direction of motion of the skewback (13) on the slotted eye (25) on the cover plate (4) and the handle (3) is corresponding, hole (20) is corresponding with the hole (21) on the lock body (1) so that be screwed cover plate (4), and the cavity (24) on the snap close (6) is corresponding with the front end on dead bolt (2) band inclined-plane (23).

Spring (5) and available other flexible member of spring (7) replace.

The axis of guide (15) on the handle (3) can be one or more, preferably 2, is positioned at the both sides of boss (10); The quantity of the guide cylinder (17) on the cover plate (4) is identical with the quantity of the axis of guide (15).

The end that snap close (6) is gone up with dead bolt (2) ramp (23) is touched mutually can be made into inclined-plane (22).

Lock body (1) and snap close (6) are installed on respectively on the two fan windows of sliding sash, can move with sliding sash.When closing window, along with the move toward one another of two fan windows, the inclined-plane (22) of snap close (6) front end collides with the inclined-plane (23) of dead bolt (2) front end, and the interaction on inclined-plane makes the front end withdrawal lock body (1) of dead bolt (2).When window continues motion and when making dead bolt (2) front end enter in the cavity (24) of snap close (6), dead bolt (2) is promoted by spring (5) and resets, and then pins sliding sash automatically.

When windowing, press handle (3) and make skewback (13) drive dead bolt (2) retraction,, and then realize unblanking, windowing action until the front end disengaging snap close (6) of dead bolt (2) by triangular ramp (9).Finish window after, unclamp handle (3), under the effect of spring (7), handle (3) resets, and simultaneously, has removed the pressure of diabolo inclined-plane (9), dead bolt (2) is under the effect of spring (5) and reset.

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, rational in infrastructure, safe and reliable, 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.

Figure one is the schematic diagram of lock body.

Figure two is schematic diagrames of dead bolt and spring.

Figure three is schematic diagrames of handle and spring.

Figure four is schematic diagrames of cover plate.

Figure five is schematic diagrames of snap close.

Figure six is schematic diagrames that dead bolt stretches out state.

Figure seven is schematic diagrames of dead bolt retracted state.

As seen, this slide window lock is made up of lock body (1), dead bolt (2), handle (3), cover plate (4), spring (5), snap close (6) from figure one to figure seven.Lock body (1) middle part is boss (10), and boss (10) both sides are groove (12).Two of the fluting (8) at middle part, dead bolt (2) back and fluting (11) is the triangular ramp (9) of symmetry projection, fluting (8) is positioned at above the boss (10) and spring (5) is housed, fluting (11) matches with boss (10), and triangular ramp (9) is arranged in groove (12) thereby blocks boss (10).Dead bolt (2) can be done the linear directional motion along boss (10), and dead bolt (2) front end inclined-plane (23) can be stretched out from the fluting (14) of lock body (1) or withdraw.Anterior 2 skewbacks (13) of handle (3) are contained in the groove (12) of lock body (1), and the slip that matches with triangular ramp (9) on the dead bolt (2).The axis of guide (15) at handle (3) rear portion is entangled in hole (18) on the guide cylinder (17) on the cover plate (4), and withstands the spring (7) of the middle dress in hole (16) on the axis of guide (15).The sidewall (19) of cover plate (4) withstands an end of spring (5) and makes its other end withstand the front end that dead bolt (2) is gone up fluting (8).The direction of motion of the skewback (13) on the slotted eye (25) on the cover plate (4) and the handle (3) is corresponding, and hole (20) are corresponding with the hole (21) on the lock body (1) so that be screwed cover plate (4).Cavity (24) on the snap close (6) is corresponding with the front end that inclined-plane (22) and dead bolt (2) are gone up band inclined-plane (23).

Hole (26) on the lock body (1) and the hole (27) on the snap close (6) are installing hole, lock body (1) and snap close (6) can be installed in respectively on the two fan sliding sashs by these holes, and move with window.
