Abstract
The utility model discloses a cam lock of electric equipment, and aims at providing the cam lock which is simple in structure and flexible to open and is applied to the electric equipment. The cam lock adopts the technical scheme as follows: the cam lock comprises a lock sleeve and a lock core capable of being rotationally mounted in the lock sleeve, wherein semispherical first grooves uniformly distributed in the circumferential direction of the lock core are formed in the circumferential surface of the lock core; annular second grooves are formed in the positions, corresponding to the first grooves, on the lock core; the two first grooves and the two second grooves are respectively formed in one end close to the key input end and the other end opposite to the key input end on the circumferential surface of the lock core; balls are arranged between the first grooves and the second grooves; at least one through hole communicated with the second groove and the exterior of the lock sleeve and used for the balls to pass through are formed in the lock sleeve; and a plug is arranged in the through hole.
Description
Technical field
The utility model relates to a kind of lockset, and more particularly, it relates to the turning-bolt lock that uses on a kind of electric fixtures.
Background technology
The turning-bolt lock that uses on the electric fixtures of the prior art is by lock core, lock tube and be installed in locking mechanism in lock core, the lock tube and cooperate and to form, and after the locking mechanism contact locked, lock core can rotate in lock tube.Lock core need carry out axial location in lock tube; Guarantee that lock core does not slide vertically; Need certain contact simultaneously between lock core and the lock tube and guarantee that lock core does not rock when rotating; Therefore cooperates between lock core and the lock tube and has relatively high expectations, thus lock core locking mechanism in lock tube, rotates suitable cunning, also want to have certain positioning function between the lock core lock tube.After long-time the use, have certain wearing and tearing between lock core, locking mechanism and the lock tube, influence the use of turning-bolt lock.
In order to improve the cooperation between lock core and the lock tube, prior art also has the proposition solution, as disclosing a kind of anti-theft lock among the Chinese patent CN2700480Y; Comprise key, lock core and lock core cover, lock core is provided with pellet shot from a slingshot and tablet lock stator, and locking plate one side is provided with the boss of ccontaining ball; Boss is provided with groove, and the locking plate opposite side is provided with pin, and boss is arranged on the middle part of locking plate one side; The boss side surfaces setting helps slide plate; Helping slide plate is one-sided or the bilateral setting, is semicircle or circular arc, helps slide plate through 90 ° of vertical locking plate one sides that are arranged on after reversing.Such structure is provided with complicacy, the underaction of unblanking.
Summary of the invention
To the deficiency that prior art exists, the purpose of the utility model is to provide the turning-bolt lock that uses on a kind of simple in structure, electric fixtures flexibly of unblanking.
For realizing above-mentioned purpose; The utility model provides following technical scheme: a kind of electric fixtures turning-bolt lock; Comprise lock tube and the lock core that is installed in rotation in the lock tube; The periphery of said lock core is provided with first groove, and the position corresponding with first groove is provided with second groove of annular on lock tube, is provided with ball between said first groove and second groove; At least be provided with connection second groove and lock tube outside on the said lock tube and be used for through hole, be provided with plug in the said through hole through ball.
Through adopting technique scheme, make that the friction between lock core and the lock tube is rolling friction, the slip resistance between the two reduces, and unblank flexibly, and total is all simpler.
The utility model further is set to: said first groove is a hemispherical groove, and circumferentially evenly distributed along lock core.
Through adopting technique scheme, further limit the structure of first groove, make structure rationalize more, first groove of circumferential evenly distributed setting makes the frictional force between lock core and the lock tube further reduce.
The utility model further is set to: said first groove and second groove all have twice, place respectively on the lock core periphery near the other end of key insertion end with relative key insertion end.
Through adopting technique scheme, further limit the structure of first groove and second groove, make structure rationalize more.
Description of drawings
Fig. 1 is the structural representation of the utility model electric fixtures turning-bolt lock embodiment.
The specific embodiment
With reference to Fig. 1 the turning-bolt lock embodiment that uses on this practical electric fixtures is further specified.
The turning-bolt lock that uses on a kind of electric fixtures, this turning-bolt lock are installed in door cashier's office in a shop usually, the mode that adopts two cover turning-bolt locks to be oppositely arranged; Every cover comprises parts such as lock tube 1, lock core 2, ball 3, through hole 4; Wherein lock core 2 is installed in rotation in the lock tube 1, on the periphery of lock core 2, is provided with first groove 21 near keyhole end, and the position of the other end also is provided with first groove 21; The position of corresponding first groove 21 is provided with second groove 11 of annular on the lock tube 1; Be provided with ball 3 at first groove 21 and 11 of second grooves, on lock tube 1, have at least a connection second groove 11 to be used for through hole 4, be provided with plug in the through hole 4 through ball 3 with lock tube 1 outside.In the present embodiment; First groove 21 is hemispherical groove, and circumferentially evenly distributed along lock core 2, also can be the full annular groove; When assembling; Lock core 2 is put into lock tube 1, and ball 3 pours between first groove 21 and second groove 11 via through hole 4 and forms the circular passage and get final product then, with plug through hole 4 is blocked after the installation to get final product.The lock core 2 of present embodiment and the ball 3 between the lock tube 1 have formed the annexation of rolling bearing; Frictional force between lock core 2 and the lock tube 1 is little; And lock core 2 and not direct friction generation loss of lock tube 1, ball 3 has also played the effect of locating to the axial location of lock core 2 in lock tube 1 in first groove 21 and second groove 11 simultaneously.
