The specific embodiment

As shown in Figure 1 to Figure 3, the anti-theft lock of sliding window that provides of the utility model is made up of the lock body 2 of side window 1 one end side surface bottom and the tooth bar 4 that is horizontally set on 3 times window frame medial surfaces of outer side window in can being fixed on; Described lock body 2 comprises lock box 5, lock core 6, dead bolt 7, guide pad 8, leaf spring 9 and lock cover 10; Lock box 5 has rectangular shape, and middle side part is equipped with lock cylinder 6 on its inner bottom surface, and downside is equipped with dead bolt 7, guide pad 8 and leaf spring 9, and is formed with a vertical rectangular opening 11 on the long limit of one side; The inside of lock core 6 is provided with the fan-shaped limited block 12 of available key turns 90 degree; Dead bolt 7 is special-shaped platy structure, one side centre stretches out and forms a braking boss 13 that can pass vertical rectangular opening 11, and the top of opposite side form to its inboard depression one slidably insert lock core 6 downsides and front end can with fan-shaped limited block 12 contacted convex platforms 14 and a lower convex platform 15, the centre of lower convex platform 15 offers a horizontal rectangular opening 16, and laterally an outwards outstanding braking pin shaft 17 then is equipped with on the right side in the rectangular opening 16; Guide pad 8 passes horizontal rectangular opening 16 and is fixed on the inner bottom surface of lock box 5; Leaf spring 9 is fixed between the right side inwall of the front end of lower convex platform 15 and lock box 5; Also form a hole 22 identical on lock cover 10 and the long limits of lock box 5 corresponding sides, then be provided with two circular hole 18 and slotted holes 19 that can pass lock core 6 and braking pin shaft 17 respectively on its end face with vertical rectangular opening 11.Be formed with many zigzag location-plates 20 that are parallel to each other along its width on the described tooth bar 4, two side ends is along the outstanding convex edge 21 with anti-end effect that is formed with of location-plate 20 directions.The length of described convex platform 14 is less than the length of lower convex platform 15.The anti-theft lock of sliding window that the utility model provides is lock body 2 to be fixed on the bottom of close outer side window 3 one end side surface on the interior side window 1, and tooth bar 4 levels are installed near on 3 times window frame medial surfaces of outer side window of interior side window 1 one ends.The length controlled of tooth bar 4 can not arbitrarily pass in and out built in the head of people when utilizing this to be locked under the maximum opening situation locking sash, otherwise does not just have antitheft effect.When the user need open the window when ventilating, it must open theftproof lock earlier, be that it can insert key in the keyhole on the lock core 6, rotate counterclockwise 180 degree then, at this moment, with the contacted fan-shaped limited block 12 of key the solid line position from Fig. 1 is become dotted line position, thereby dead bolt 7 can be moved along left and right directions.Subsequently, the user is with regard to the method for the available braking pin shaft 17 be exposed at lock cover 10 outsides of sliding the to the right dead bolt 7 that moves right, and leaf spring 9 will be subjected to the extruding of lower convex platform 15 front ends in this process.At this moment, the braking boss 13 in dead bolt 7 left sides will be from the inside of vertical rectangular opening 11 outside indentation lock boxes 5, thus sliding window sash arbitrarily.When waiting to reach desired position, take-off the brake bearing pin 17, at this moment, the leaf spring 9 that is in pressured state will rely on elastic force that dead bolt 7 is promoted left, be stuck on the location-plate 20 of tooth bar 4 up to the braking boss 13 on the dead bolt 7 till.Owing to guide pad 8 is installed in the horizontal rectangular opening 16 in lower convex platform 15 centres, thereby skew can not appear during dead bolt 7 move left and right.At last key is clockwise rotated 180 degree, at this moment, fan-shaped limited block 12 will be got back to the solid line position among Fig. 1, and the contact of one side straight flange is at convex platform 14 front ends of dead bolt 7, thereby dead bolt 7 can't move.The anti-theft lock of sliding window that the utility model provides need use supporting key to open, and so just can prevent that the lawless person is in inlet chamber outside window.In addition, too many for fear of the theftproof lock quantity on the different sash occurring in the same resident family, need corresponding one by one problem during the switch window, that each household can be used is many lock core 6 and the key of the same model of sliding anti-theft lock adapted, and using like this will be very convenient.This theftproof lock also is applicable to sliding door.
