The purpose of this utility model is to provide a kind of improved button to move sash lock, it can be effectively and securely locking move the formula window, and easy to use, good looking appearance.

The technical solution of the utility model as shown in Figure 1, it comprises panel, lock housing, press button, lock pin and securing member etc., its major technique feature is that lock pin (6) on-line equipment is on the housing that is made of panel (1) and lock housing (7), lock pin is provided with locating slot (5) and back-moving spring (8), panel is stretched to for button (4) in the upper end, end passes the lock housing bottom, press button (2) device is in the elongated hole (13) of panel, can slide along the hole, inner fixing with dead bolt (3), and be connected with tight bolt (10) by extension spring (11), dead bolt (3) is provided with microscler locating hole with the both sides that press button (2) is connected, and string is placed in fastening bolt (10) and (12) respectively; Guarantee that dead bolt can accurately insert in the locating slot (5) of lock pin.Like this when pressing button (4) in the direction of arrows, the tension of extension spring (11), dead bolt inserts locating slot, and lock pin can not be resetted, thereby realizes locking.Otherwise, promoting press button (2) to the direction of arrow, dead bolt just breaks away from locating slot, and lock pin is under the effect of back-moving spring (8) and reset, and lock is unlocked, and has so just finished to lock and the overall process of unlatching.

Fig. 1 is the sectional drawing that button moves sash lock.

Fig. 2 is the plug housing sectional drawing that button moves sash lock.

The utility model is when making, and the pin-and-hole of the body bar of lock pin (6) part and lock housing bottom is preferably square, to guarantee the relative position of locating slot (5) and dead bolt (3).In addition, consider that the intensity of aluminium alloys empty stomach stile is relatively poor, preferably equipped arc plug housing (16) as shown in Figure 2 on another fan stile that lock pin (6) inserts is to strengthen its fastness.

Concrete install as follows: straight stile front (centre position) of interior window open one with the hole of moving the sash lock corresponding size, also open one in the stile back side corresponding and the straight stile of exterior window and can make the flexible hole of lock pin with lock pin, will move sash lock then and be screwed.If adapted plug housing (16) only needs its on-line equipment is got final product on the pin hole position of the straight stile of exterior window, because pin hole (15) is arranged on the plug housing, there is screw (17) at two ends, install very convenient.Like this, when window was closed, the straight stile of two fan windows was in corresponding superimposed position, and push button (4), it is that window is locked that lock pin inserts plug housing.

The utility model is owing to adopt lock pin to the superimposed lock mode that runs through of two stiles, compared with prior art, has not yielding, also not fragile and pry open, locking effect is good, and is safe and reliable, the characteristics such as long service life, and easy to use, good looking appearance is applicable to the various formula windows that move.
