Abstract
The invention discloses a crescent lock, which comprises a base and a cam lock disk matched with a lock catch fixed and arranged on a window frame. An axle seat is integrally arranged on the base, and the cam lock disk is coupled on the axle seat. The invention is characterized in that an elastic positioning device is arranged between the cam lock disk and the base; the invention has the advantages that the structure is simple, the cost is low, because the elastic positioning device is arranged between the cam lock disk and the base, and the relative rotation between the cam lock disk and the base requires a certain external force, when the window is closed, even through a gap exists between two window casements, the window lock is uneasily to be picked; a lock disk locking mechanism is additionally arranged between the cam lock disk and the base, the cam lock disk is locked on the base through a lock core and a dead bolt, and the mutual rotation between the cam lock disk and the base can not happen, thereby greatly increasing the safety and the insurance of the window lock.
Description
Technical field
The present invention relates to a kind of lockset, especially relate to a kind of crescent lock.
Background technology
Window is a requisite ingredient in the building construction, and for antitheft, people have installed sash lock on window, and for this reason, various in the market sash locks are a feast for the eyes.The sash lock of some function singlenesses, for example be contained in the cam lock between the two fan windows, as long as the cam lock collar in the cam lock is coupling on the frame of a fan window, snap close in the cam lock is fixedly installed on the corresponding frame of another fan window, the rotating cam lock collar makes it to slip in the snap close, can be with the window locking, though this cam lock is relatively simple for structure, but because the cam lock collar is rotated more easily, when having the slit between the two fan windows, this cam lock is just pried open than being easier to, and safety is bad.
Summary of the invention
Technical problem to be solved by this invention provides the good and simple in structure crescent lock of a kind of safety.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of crescent lock, comprise pedestal and the cam lock collar that matches with snap close on being fixedly installed on window frame, be wholely set axle bed on the described pedestal, described cam lock collar is coupling on described axle bed, be provided with elastic positioning device between described cam lock collar and the described pedestal, described elastic positioning device comprises spring shaft coupling and the coaxial outer sliding chute seat of described axle bed that is arranged on, be provided with detent in the described cam lock collar, be wholely set first locating convex block on the upper surface of described spring shaft coupling, be wholely set second locating convex block on the lower surface of described spring shaft coupling, described first locating convex block is fastened in the described detent, and described second locating convex block and described sliding chute seat are slidingly matched.
Described sliding chute seat is wholely set on described pedestal.
Be provided with the lock collar locking mechanism between described cam lock collar and the described pedestal.
Described lock collar locking mechanism comprises lock core and dead bolt, described cam lock collar is provided with lock core hole and lock core fixed mount, described lock core penetrates in the described lock core hole and by described lock core fixed mount and fixes, the front end of described lock core is wholely set eccentric lock pin, one end of described dead bolt is provided with lockpin hole, the width of described lockpin hole is greater than the height of described lockpin hole, described lock pin stretches in the described lockpin hole, described pedestal is provided with dead bolt hole, and the other end of described dead bolt and described dead bolt hole are slidingly matched.
The coaxial lining that is arranged with between described cam lock collar and the described axle bed.
Described cam lock collar is provided with stopper slot, and described pedestal is provided with limited block, and described limited block and described stopper slot are slidingly matched.
Described cam lock collar is provided with and is fixedly installed on the chute that the snap close on the window frame is slidingly matched.
Compared with prior art, advantage of the present invention is simple in structure, cost is lower, owing to be provided with elastic positioning device between cam lock collar and the pedestal, make relatively rotating between cam lock collar and the pedestal need apply certain external force, therefore when window was closed, even have the slit between the two fan windows, sash lock also was not easy to be pried open; And between cam lock collar and pedestal, added the lock collar locking mechanism, and by lock core and dead bolt the cam lock collar is locked on the pedestal, make between the two and can not rotate mutually, increased the safety and the safety of sash lock widely.
