Abstract
The utility model discloses a lock, which comprises a lock sleeve and a lock cylinder rotatably mounted inside the lock sleeve. The lock is characterized in that a first groove is arranged on the circumferential face of the lock cylinder, an annular second annular groove is arranged on the lock sleeve corresponding to the first groove, a ball is disposed between the first groove and the second groove, at least one through hole used for access for the ball and communicated with the second groove and outside of the lock sleeve is arranged on the lock sleeve, and a plug is arranged in the through hole. The rolling friction between the lock cylinder and the lock sleeve reduces slide resistance between the lock cylinder and the lock sleeve and reduces loss, also matching of the ball with the grooves can directly limit axial position of the lock cylinder, the lock simplifies assembly process of the lock cylinder and the lock sleeve, and assembly process is completed only by aligning the lock cylinder with the lock sleeve, installing the ball into the through hole and plugging the through hole.
Description
Technical field
The utility model relates to lockset, a kind of specifically locate mode between lock core and the lock tube has been carried out improved lockset.
Background technology
Lockset 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 locking mechanism unlocked, 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 fitness is had relatively high expectations between lock core and the lock tube, need lock core and locking mechanism in lock tube, to rotate, also want to have certain positioning function between the lock core lock tube, after long-time the use along sliding, have certain wearing and tearing between lock core, locking mechanism and the lock tube, influence the use of lockset.In order to improve between lock core and the lock tube, multiple solution is arranged in the prior art, as disclosing a kind of anti-theft lock among the Chinese utility model patent CN2700480Y, comprise key, lock core and lock core cover, lock core is provided with pellet shot from a slingshot and tablet lock stator, locking plate one side is provided with the boss of ccontaining ball, is provided with groove in the boss, and the locking plate opposite side is provided with pin.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.Helping slide plate is semicircle or circular arc.Help slide plate through 90 ° of vertical locking plate one sides that are arranged on after reversing.This utility model is because locking plate is provided with ball and semicircle helps slide plate, and the frictional force when having reduced the lock core rotation between locking mechanism and the lock tube makes and unblanks to become more flexible.
The utility model content
The purpose of this utility model is: provide and be convenient between a kind of lock core and the lock tube install, lockset is flexibly rotated in accurate positioning.
The technical solution of the utility model is:
A kind of lockset, comprise lock tube and be installed in rotation on the interior lock core of lock tube, it is characterized in that: first groove is arranged on the periphery of lock core, there is second groove of annular the position corresponding with first groove on lock tube, between first groove and second groove, be provided with ball, on lock tube, have at least one to be communicated with second groove and lock tube outside and to be used for through hole, plug is arranged in the through hole by ball.
Supplementary technology scheme of the present utility model is:
Preferably, described first groove is an annular groove.
Preferably, described first groove is the dome-type groove, and circumferentially evenly distributed along lock core.
Preferably, described first groove and the second corresponding with it groove have twice, lay respectively on the lock core periphery position near key insertion end and tail end.
Preferably, described first groove and the second corresponding with it groove are arranged on the position of close tail end on the lock core periphery.
The beneficial effects of the utility model are: the friction between lock core and the lock tube is rolling friction, makes the two slip resistance reduce, and loss reduces, and ball and groove fit can directly play the effect that limits the lock core axial location simultaneously.And the utility model has also been simplified the assembling process of lock core, lock tube, only needs lock core is put as after the lock tube alignment, by the ball of packing in the through hole, through hole is blocked again and to get final product.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the schematic diagram of a specific embodiment of the utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Specific embodiment of the utility model 1, as shown in Figure 1, a kind of lockset, this lockset is installed on the door usually, the mode that adopts two cover locksets to be oppositely arranged, every cover comprises lock tube 1, lock core 4, ball 3, through hole 4 parts such as grade, wherein lock core 4 is installed in rotation in the lock tube 1, position near keyhole end and tail end on the periphery of lock core 4 is respectively equipped with first groove 5, there is second groove 6 of annular the position corresponding with first groove 5 on lock tube, be provided with ball 3 at first groove 5 and 6 of second grooves, on lock tube 1, have at least one to be communicated with second groove 6 and lock tube 1 outside and to be used for through hole, in the through hole 3 plug is arranged by ball 3.In the present embodiment, first groove 5 is annular grooves.In when assembling, lock core 4 is put into lock tube 1, ball 3 is poured in the circular passage that forms between first recessed 5 grooves and second groove 6 via through hole 2 get final product then, with plug through hole 2 is blocked after the installation and get final product.The lock core 4 of present embodiment and the ball 3 between the lock tube 1 have formed the annexation of rolling bearing, frictional force between lock core 4 and the lock tube 1 is little, and the not direct friction generation loss of lock core 4 and lock tube 1, ball 3 has also played the effect of location to the axial location of lock core 4 in lock tube 1 in recessed 5 grooves and second groove 6 simultaneously.
In the above-described embodiments, described first groove also can be the dome-type groove, and circumferentially evenly distributed along lock core.
In the above-described embodiment, described first groove and the second corresponding with it groove also can only be arranged on the position of close tail end on the lock core periphery, and the other end is spacing by boss.
Disclosed all features in this manual, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this manual (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
