Description

The slide door or window automatic locking

The utility model relates to the door and window lock, particularly alumium alloy door and window automatic locking that push-and-pull fastens.

Conventional alumium alloy door and window push-pull lock, by fixed hook, activity collude, three big major parts such as holder constitute, collude and the fastening of fixed hook or closing, opening of disengaging realization door and window by activity, but because movable colluding with the direction of relative movement of fixed hook follows the door and window direction of motion perpendicular, when opening door and window, activity to be colluded disengagement earlier; When closing the doors and windows, activity be colluded and fixed hook fastens, in other words, opening and closing door and window will be at twice, finished by two different actions, and this is not too convenient, also unreasonable in daily use.On the other hand, conventional aluminium alloy door sash lock is easy to generate " stand-off thread " phenomenon, think promptly that activity is colluded with fixed hook to fasten, but button connection in fact, therefore, people often after door and window fastens, also must try to push away, see really not locking, very trouble.

The purpose of this utility model is for overcoming the deficiencies in the prior art part, provide a kind of open and close door and window need only one-time action finish, easy to use, simple, reliable slide door or window automatic locking is made in the button interlock.

The purpose of this utility model is achieved by the following technical solution: the slide door or window automatic locking, include the holder that is fixed on the door and window, the fixed hook that cooperates with activity hook connection on another door and window is colluded and is fixed in the activity that is loaded on the holder, special feature is that holder has hole slot, activity is colluded and is passed and be articulated in the hole slot bottom, and the lozenges of the button that the effect end that activity is colluded is interior with being loaded on hole slot contacts; Activity collude and button between be connected with back-moving spring.

Below in conjunction with drawings and Examples the utility model and advantage thereof are further elaborated.

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

Fig. 2 is the A-A sectional view of Fig. 1.

See figures.1.and.2, the fixed hook 1 of present embodiment, holder 3 are loaded on respectively on the door and window of a pair of mutual butt joint, 2 hole slots 8 that pass holder 3 are colluded in the activity that cooperates with fixed hook 1 button connection, hole slot 8 bottoms through axle 7 hinged securement seats 3, and activity is colluded 2 and is the multistage meander-like, one end is and the eave tile of fixed hook 1 snapping that the other end is stressed effect end; The effect end contacts with the lozenges 6 of button 5 in the hole slot 8.Two back-moving springs 4 are housed in the hole slot 8 in the present embodiment altogether, back-moving spring 4 be in and button 5 between; When closing the doors and windows, the promotion door and window makes fixed hook 1 and activity collude 2 and collides, because movable 2 the eave tile of colluding has guiding surface, activity is colluded 2 and is stressedly rotated around axle 7, and compression reseting spring 4, when activity collude 2 fasten with fixed hook 1 after, back-moving spring 4 restores to the original state, and makes eave tile upper and lower, left and right chucking, realizes automatic blocking; When door and window, press button 5 with have gentle hands, lozenges 6 on the button 5 moves down thereupon, because 2 effect end in contact is colluded in lozenges 6 and activity, the component of lozenges 6 acts on activity and colludes on 2 the effect end, makes activity collude 2 around axle 7 counter-rotation, and eave tile is spun off from fixed hook 1, the slide door or window of taking advantage of a situation is realized unblanking, door window.

The advantage of this structure is: the action of closing door and window, locking or unlocking, door window combined, Finish under one-time action, simple to operate, easy to use, snapping is solid and reliable, is a kind of novelty The push button automatic door/window lock.
