The sash window prying-resistant latch is provided with a latch cylinder, an oblique movable lug latch, a compression spring, a rotary handle and a spacing screw; the front end of the latch cylinder is provided with an axial slide groove and a radial slide groove; the rear end of the latch cylinder extends to be a disc-shaped base which is provided with a screw hole; the included angle theta between the oblique surface at the front end of the oblique movable lug latch and the axis is 45 degrees-60 degrees; the front and the back of the oblique movable lug latch are provided with spacing screw holes; the rotary handle is connected with the rear end of the oblique movable lug latch; the compression spring is sleeved on the middle part of the oblique movable lug latch; the compression spring and the oblique movable lug latch are placed in the latch cylinder; the extending part at the rear end of the oblique movable lug latch is connected integrally with the rotary handle by a tightening screw; and the spacing screws are screwed into corresponding spacing screw holes.
Description
Technical field
The utility model relates to a kind of sliding sash, especially relates to a kind of sliding sash pick-proof latch with strong pick-proof effect.
Background technology
Existing sliding sash window button mainly contains two types: first kind is in the both sides of sliding sash an austral window button to be set respectively to fasten window frame, and another kind is that the movement that a secondary crescent moon window button limits sliding sash is set in the coincidence part office of sliding sash.The shortcoming of austral window button is to occur easily breaking off relations, and perhaps the people is for forcing sliding sash to move up and down also to allow its unhook.The shortcoming of crescent moon window button is distortion to occur easily and damage, and perhaps firmly the horizontal sliding window frame can allow the breakage of window button.Therefore, this window button of two types breaks down easily or damages, and the pick-proof poor-performing.
Summary of the invention
The purpose of this utility model is intended at the existing above-mentioned shortcoming of existing austral window button, a kind of window button that can make adjacent sliding sash constitute a firm integral body is provided, be connected as a single entity by the skeleton of latch with adjacent sliding sash, thereby realize closing window and strengthen the sliding sash pick-proof latch of its pick-proof effect.
The utility model is provided with latch tube, oblique movable lug latch, compression spring, swing handle and stop screw; The front end of described latch tube is provided with and endwisely slips groove and radially slide groove, and the latch tube rear end extends and is the dish type pedestal, and described dish type pedestal is provided with screw hole; The external diameter of described oblique movable lug latch is slightly less than the internal diameter of latch tube, tiltedly inclined-plane and the axis angle θ of movable lug latch front end are 45 °～60 °, tiltedly be provided with 2～4 spacing screws that cooperate with stop screw before and after the place, movable lug latch outer, swing handle is connected with the oblique rear end of movable lug latch by holding screw, and can drive oblique movable lug latch and move forward and backward and rotate; The middle part that the compression spring is inserted in oblique movable lug latch, compression spring and oblique movable lug latch are placed in the latch tube, and tiltedly the extension of movable lug latch rear end is connected as a single entity by holding screw and swing handle; Stop screw screws in the corresponding spacing screw, and tiltedly the related stop screw of movable lug latch can move forward and backward and along radially sliding the groove left rotation and right rotation along the groove that endwisely slips.
Can regulate the length of oblique movable lug extension according to the thickness of window frame skeleton.
During assembling, offering a slightly larger in diameter in the through hole of latch tube external diameter near the middle part of an indoor fan sliding sash skeleton, and offering a slightly larger in diameter in half through hole of oblique movable lug external diameter at the correspondence position of another fan sliding sash skeleton.When stop screw is positioned at when endwisely slipping groove, tiltedly the inclined-plane of movable lug should and embed in the indoor sliding sash skeleton towards the outside of indoor sliding sash, by screw latch tube pedestal is connected with the sliding sash skeleton then.
When closing window, two fan sliding sashs are drawn back tiltedly movable lug latch recession automatically under the effect on inclined-plane toward both sides; When the traversing pin hole position to another fan sliding sash of oblique movable lug latch, under the effect of compression spring, tiltedly the movable lug latch inserts in the pin hole automatically; For preventing being prized, the swing handle that can turn clockwise impels stop screw to enter to radially slide and carries out self-locking in the groove.
When opening window, earlier swing handle is rotated counterclockwise, when stop screw is positioned at when endwisely slipping the groove position, spurs to move behind the oblique movable lug latch by swing handle and can push two fan sliding sashs open.
The utility model adopts the structure of high strength latch that adjacent sliding sash is connected to a firm integral body, utilizes the design of oblique movable lug that latch is inserted in the pin hole automatically again.In addition, also set up self-locking device to improve its pick-proof performance.Compare with existing window button, the utlity model has characteristics such as simple in structure, easy to operate, that the pick-proof performance is strong.
