Abstract
The utility model discloses a lockset which comprises a lock shell, an inner sleeve and a lock cylinder. The lock cylinder is arranged in the inner sleeve and can rotate, and a lock hole is formed in the lock cylinder. The lockset is characterized in that the lock cylinder and the inner sleeve are arranged with the same diameter, a check ring is arranged at the bottom of the inner sleeve, a groove is formed in the check ring, a protruding block matched with the groove is arranged on the lock cylinder and moves within the range of the groove, the top face of the lock cylinder and the top face of the inner sleeve are arranged on the same horizontal plane, a flange groove is further formed in the lock cylinder, a flange column is arranged in the flange groove, the flange column and the a lock sheet are matched to move, and a through groove matched with the flange column is formed in the inner sleeve. Therefore, the rotating range of the lock cylinder can be limited by the groove, unlocking is facilitated, structural assembling is more convenient, and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of lockset, particularly be a kind of lock that has more feel and can sound.
Background technology
Lock refers to the device of sealing on objects such as being added in door, chest, drawer, is articles for use indispensable in the mankind's daily life, need lock core to rotate in lock housing just to complete to unblank, and the rotation amplitude of lock core has restriction while unblanking.In prior art, between lock core and inner sleeve, conventionally adopt plectrum spacing, for limiting the rotation amplitude of lock core, but very inconvenient in the time of this limit method assembling, will affect production efficiency like this, and lock core and inner sleeve are not same footpaths, the end face of lock core and the end face of inner sleeve be not at same level line, be that the end face of lock core is exposed at inner sleeve outside, just put a Ka Tai of needs in addition in like this lock core is blocked, when lock core packs inner sleeve into, owing to can not stretching in inner sleeve, component in lock core very easily eject, and assembling is gone wrong, very inconvenient.
Summary of the invention
In view of the problem that known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of convenient lock that assembles.
For solving the problems of the technologies described above, the utility model takes following technical scheme to complete:
A kind of lockset, comprise lock housing, inner sleeve and lock core, it is interior and rotatable that described lock core is arranged on inner sleeve, in described lock core, be provided with lockhole, it is characterized in that: described lock core and inner sleeve arrange with footpath, described inner sleeve bottom is provided with back-up ring, described back-up ring is provided with groove, described lock core is provided with the projection and the projection that match with groove and moves within the scope of groove, the end face of described lock core and the end face of inner sleeve are in same level, on described lock core, be also provided with rib groove, in described rib groove, be provided with rib post, described rib post coordinates mobile with locking plate, in described, put and be provided with the groove matching with rib post.Described rib groove below is provided with steel ball groove, in described steel ball groove, is provided with steel ball, and described steel ball is connected with spring, puts in described and is provided with the through hole matching with steel ball.Described through hole is provided with two, and described through hole setting party is to identical with the rotation direction of lock core, and the spacing between described through hole and the length of groove match.
The beneficial effects of the utility model are: the projection on lock core moves in the groove of inner sleeve, so just can utilize the slewing area of indentation limitations lock core, conveniently unblank, and it is convenient that lock core and inner sleeve arrange rear assembling with footpath, the used time is not utilized rib post to block lock core and prevents that lock core from rotating, such structure is convenient installation both, improved again production efficiency.
Accompanying drawing explanation
Further describe by reference to the accompanying drawings again embodiment below:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model sectional view.
The specific embodiment
Accompanying drawing has represented structure of the present utility model and embodiment, each details of embodiment is described below more by reference to the accompanying drawings, this lockset, comprise lock housing 1, inner sleeve 3 and lock core 2, it is interior and rotatable that described lock core 2 is arranged on inner sleeve 3, in described lock core 2, be provided with lockhole 4, described lock core 2 arranges with footpath with inner sleeve 3, be just to match with inner sleeve 3 in lock core 2 placement inner sleeves 3, described inner sleeve 3 bottoms are provided with back-up ring 5, this back-up ring 5 is for blocking lock core 2, prevent from dropping out after lock core 2 from packing inner sleeve 3 into, described back-up ring 5 is provided with groove, described lock core 2 is provided with the projection and the projection that match with groove and moves within the scope of groove, be that back-up ring 5 is provided with groove, projection on lock core 2 just falls into groove, in groove, move only, and this groove has certain length, so just can limit the amplitude that lock core 2 rotates, for example rotate 90 ° for best angle, the end face of the end face of described lock core 2 and inner sleeve 3 is in same level, like this when assembling lock core 2 to put into inner sleeve 3 just more convenient, greatly saved installation time, on described lock core 2, be also provided with rib groove 6, in described rib groove 6, be provided with rib post, described rib post coordinates mobile with locking plate, described inner sleeve 3 is provided with the groove matching with rib post, when lock is lock-out state, locking plate will be released and block locked groove, thereby realize locking, now at the promotion lower block side column of locking plate, release the groove putting in embedding, thereby effectively prevent that lock core from rotating under abnormal conditions, effectively antitheft, after correct key inserts, lock tooth return, thus drive rib post to retract, and so just rotatable lock core is unblanked, described rib groove 6 belows are provided with steel ball groove 7, in described steel ball groove 7, be provided with steel ball, described steel ball is connected with spring, described inner sleeve 3 is provided with the through hole matching with steel ball, described through hole is provided with two, described through hole setting party is to identical with the rotation direction of lock core 2, spacing between described through hole and the length of groove match, when lock core 2 does not rotate, spring can eject steel ball and embed in through hole, when key inserts lock core 2 rotation, under external force, steel ball can be retracted, because position and the groove of two through holes matches, therefore after lock core 2 rotations are unblanked, steel ball can continue again to eject another through hole of embedding, so just can effectively prevent that lock core 2 from arbitrarily rotating.Certainly through hole also can arrange three, centered by middle steel ball, puts both sides and is respectively provided with one, even if different like this lock rotation directions is different, also applicable.Although the utility model simplicity of design, can reach very useful effect, Bi Nenggei enterprise brings better benefit.
