Abstract

The utility model relates to a dense frame lock which comprises a lock core and a lock sleeve, wherein the lock sleeve can rotate relative to the lock core; a handle is fixed on the lock sleeve; the lock sleeve is penetrated through the rear end of the handle; a rotating sheet which can rotate following the handle is arranged at the rear end of the handle; a lock tongue extends outward from the rotating sheet; and a lock head for locking or releasing the rotating sheet is arranged at the rear end of the lock core. The dense frame lock has the beneficial effects that: the rotating sheet is arranged and is locked or unlocked by the lock core, so that the rotating sheet can be rotated for locking under an unlocked state, and the dense frame lock has a dual-locking function.

Description

A kind of intensive lock

Technical field

The utility model relates to a kind of lockset.

Background technology

The lockset that blade lock right and wrong are usually seen; Be usually used in places such as drawer, chamber door; Intensive lock is a kind of of blade lock, and in the prior art, the blade lock is general direct unblanks or lock through key; But sometimes except unblank through key or locking state, also need a kind of key that do not need can open closing state.

Summary of the invention

In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of multi-functional intensive lock.

The technical scheme that the utility model solves its technical problem is:

A kind of intensive lock; The lock tube that comprises the relative lock core rotation of lock core and ability; Be fixed with handle on the described lock tube; The rear end of described handle wears described lock tube and is fixedly connected one can be with the revolving fragment of handle rotation, and described revolving fragment is outward extended with dead bolt, and the rear end of described lock core is provided with the tapered end that can pin revolving fragment or discharge revolving fragment.

As preferably, tapered end includes the curved surface that rotates with revolving fragment outer edge coupling and restriction revolving fragment and can hold the plane that revolving fragment freely rotates, and described plane and curved surface are oppositely arranged, and change through lock core.

As preferably, connect a ball through spring on the back surface of the relative revolving fragment of lock tube, the surface of the relative lock tube of described revolving fragment is provided with two pits, and the position of the corresponding ball of the position of described two pits difference.

As preferably, lock tube is square, and the front surface of lock tube is concaved with groove backward, and described handle is arranged in the described groove.

Through key rotation lock core, when the curved surface conflict revolving fragment edge of lock core rear end tapered end, revolving fragment can't rotate; Then dead bolt is lived intensive door lock, when the planar alignment revolving fragment of tapered end, through swing handle; Revolving fragment can rotate arbitrarily, then can dead bolt be pinned or release through handle.Then during the key open mode, can also door lock be lived or release through handle.In addition, when revolving fragment was rotated in release or lock state, the ball on the lock tube just fell in the pit of revolving fragment, and prompting has been rotated and put in place.

The beneficial effect of the utility model is: the utility model pins revolving fragment or release through lock core through the setting of revolving fragment, then under released state, can also rotate through revolving fragment and pin, and has the two-bolt lock function.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain.

Like Fig. 1,2, shown in 3, a kind of intensive lock comprises the lock tube 8 that the relative lock core 1 of lock core 1 and ability rotates; Lock tube is square; The front surface of lock tube is provided with groove 7, is provided with handle 6 in the groove 7, and the rear end of handle 6 wears lock tube and is fixedly connected one can be with the revolving fragment 5 of handle rotation; Revolving fragment is outward extended with dead bolt 4, and the rear end of lock core 1 is provided with the tapered end 3 that can pin revolving fragment or discharge revolving fragment.Tapered end 3 includes the curved surface that rotates with revolving fragment outer edge coupling and restriction revolving fragment and can hold the plane 2 that revolving fragment freely rotates, and plane 2 is oppositely arranged with curved surface, and changes through lock core.Connect a ball 10 through spring 9 on the back surface of the relative revolving fragment of lock tube, the surface of revolving fragment 5 relative lock tubes is provided with two pits, and the position of the corresponding ball of the position of two pits difference.

Through key rotation lock core 1; When the curved surface conflict revolving fragment edge of lock core rear end tapered end, revolving fragment 5 can't rotate, and then dead bolt 4 is lived intensive door lock; When revolving fragment is aimed on the plane 2 of tapered end; Through swing handle, revolving fragment can rotate arbitrarily, then can dead bolt be pinned or release through handle.Then during the key open mode, can also door lock be lived or release through handle.In addition, when revolving fragment was rotated in release or lock state, the ball on the lock tube just fell in the pit of revolving fragment, and prompting has been rotated and put in place.The utility model pins revolving fragment or release through lock core through the setting of revolving fragment, then under released state, can also rotate through revolving fragment and pin, and has the two-bolt lock function.
