Abstract
The utility model belongs to a locking device for sliding doors and windows, which is characterized in that the inner side of the window of a surface shell is provided with a pressing board; the window is connected with the pressing board by an elastic moveable mechanism; a limiting clip preventing the pressing board from jumping outwards is arranged between the pressing board and the surface shell; a lock hook is transversally arranged on the side of the pressing board; a hook clasp is buckled and matched with the lock hook; a safety mechanism is arranged between the pressing board and the surface shell. Because the width of the hook clasp is small, the utility model only needs to cut a slotted hole in a frame, so relatively enhances the strength of the frame and reduces the working hours of cutting. The utility model has the advantages of simple structure, low cost, and convenient use, and is particularly suitable for doors and windows with the frames of aluminum section bars.
Description
The utility model belongs to the locking means of push-pull door and window.
Existing lock for slide door or window, Chinese patent is arranged: 88206587.4,92207008.0 and 93217822.7 etc., its structure is that a movable lock body slides up and down on fixing face-piece, latch hook and fastener cooperate the form that interlocks up and down, the structure of such lock is also too complicated, be provided with pin, the groove of positioning and guiding, pit etc., materials are many during manufacturing, when taking a lot of work, so that cost is too high; Next is that the lateral dimension of fastener is wide, need cut roomy framework hole during installation, has reduced the intensity of framework, and when taking a lot of work, the hole is big, and is not attractive in appearance.During use, break off relations with pulling the moving movable lock body of hook strip earlier, the frame of pulling again, action is trouble also.
The purpose of this utility model provides a kind of lock for windows that can finish unhook in the process of pushing.
The purpose of this utility model is finished by following technical solution, is provided with elastic panel mechanism in the notch of face-piece, establishes pressing board on the elastic panel mechanism, and latch hook is connected with elastic panel mechanism and laterally interlocks with fastener, pushes described pressing board latch hook and throws off fastener.
The pit that Gong pulls can be established in the front of described pressing board, and the back side is horizontally set with latch hook.
Described elastic panel mechanism is a pressing board with face-piece both mutually interconnected by, can pressing board can be ejected by the elastomeric objects effect again can be pressed by the mechanism of advancing.It can have multiple frame mode: example: (1) sets spring leaf between one of pressing board and face-piece.(2) hinged in both sides of pressing board and above-mentioned face-piece, and on hinged bearing pin, set torsion spring.(3) hinged in both sides of pressing board and above-mentioned face-piece, between other end and face-piece, set elastomeric objects.(4) two of pressing board respectively is provided with guide peg, and this guide peg cooperates with pilot hole on the tower ear that above-mentioned face-piece is provided with, and sets elastomeric objects between this pressing board and face-piece.(5) the hinged connecting rod in the pressing board stage casing, the other end of connecting rod and cover rabbet inside wall are hinged and set torsion spring.Or the like.
Described elastomeric objects can be: objects such as compression spring, extension spring, spring leaf, elastoplast, rubber.Select for use and set seat or hook or tower ear etc. when a certain again.
Above-mentioned notch can be closed, also can be opening, can be pit notch etc.Above-mentioned fastener can adopt structures such as frame hook, plush copper pin.
Also can set insurance institution between above-mentioned face-piece and pressing board, this insurance institution keeps pressing board to be in long opening or the mechanism of long lock state.It can adopt multiple structure, mode, is located on face-piece or the pressing board, for example:
Establish rotatable switch knob on above-mentioned pressing board or face-piece, this switch knob is provided with eccentric disc, and this eccentric disc is opened rank card and corresponding the matching of long lock rank card with relative described face-piece or the length on the pressing board.
But establish the top button of pushing on above-mentioned pressing board or face-piece, this top button opens the rank card with relative described face-piece or the length on the pressing board and long lock rank card matches to corresponding.
Be provided with the lock core of opening commentaries on classics with key on above-mentioned pressing board or face-piece, this lock core is provided with the eccentric switch block with cocked bead that the control pressing board moves.
Be provided with a pair pressing board in the window of paying face-piece, this pair face-piece with above-mentioned corresponding opposing the setting of face-piece, hinged in both sides, and on hinged bearing pin equipped torsion spring, also be provided with on this pair pressing board and prevent the outwards blocked portion of ejection, on this pair face-piece, also be provided with the lock core of paying of opening commentaries on classics with key, this pair lock core is provided with control and pays pair eccentric switch block that pressing board moves, go back hinged lever in the middle part behind at described pair of face-piece, one on this lever cooperates clasp joint with the pressure hook that above-mentioned pressing board is provided with, and the other end is interval in described pair of pressing board and pays between the eccentric switch block.
The utility model adopts the pressing board mode, and pressing board is thrown off latch hook, hand-pulled noodles shell (on the frame that frames up) is promptly opened door, by action be connected in naturally and stretch out one's hand to the process of drawing, the action nature is simple, and is more more convenient by pulling the moving slip lock body (disengagement hook) of hook strip than existing lock; The transverse gage that is fastener again is more much smaller than the fastener width of existing lock, only need vertically join and cut a slot, thereby increase the intensity of framework relatively, has reduced cutting processing man-hour; Also have because of pressing board and hinged, the torsion spring structure of face-piece employing, need not establish guiding, locating slot etc., simple in structure again, cost is low.
If establish pit on the pressing board, be convenient to finger and stretch into, conveniently draw back window, door.
If set up insurance institution, make pressing board and hook be in normally open position, prevent that then latch hook and fastener from buckling, be convenient to sometimes to lock not needing, but use when needing opening and closing; When making pressing board and hook be in long the lock, then prevent to lock the back and throw off, have insurance, theftproof performance.
If the hand synapsis of insurance institution is located on the pressing board, then in use can be more natural, convenient.
If insurance institution adopts the lock core structure that needs key to open, in the room, there is not key not open, then safer, theftproof performance is strengthened.
If set up a series of parts in addition such as relative pair face-piece, pair pressing board, then be used in and paying lock core with key turns outdoors, open lock by pressing board.
