Abstract

The utility model relates to a lock with linked cylinders. Only a lock cylinder and a shifting block which match with each other are arranged in a lock body of an existing lock generally, lawbreakers only need to unlock the single lock cylinder by all means when in technical unlocking, and the existing lock is lower in antitheft property. The lock with linked cylinders comprises a lock body and a telescopic rod mounted on the lock body, and the telescopic rod is provided with a bolt. The lock with linked cylinders is characterized in that at least two lock cylinders used for shifting the telescopic rod are mounted on the lock body, and the lock body is provided with keys matching with the lock cylinders. In the technical scheme, the lock body is generally provided with two to three lock cylinders which are in mutual linkage, and each lock cylinder only can rotate by means of inserting the correct key into each lock cylinder. A lock of a traditional single-lock-cylinder structure is improved into the lock with a plurality of lock cylinders, antitheft property of the lock is greatly improved, technical unlocking difficulty is increased, and technical unlocking time is prolonged.

Description

A kind of core lock

Technical field

The utility model relates to a kind of lockset, especially a kind of connection core lock that is used on the bicycles such as electric motor car, bicycle.

Background technology

Existing being locked in only has a parafacies interworking usually and closes lock core and expansion link in the lock body, the lawless person only needs by every means the lock core that this is unique to crack the back and just can unblank when carrying out skilled unlocking, and theftproof performance is lower.

The utility model content

The utility model provides a kind of core lock at the defective that prior art exists, and increases skilled unlocking difficulty and uncaging time, improves theftproof performance.

For this reason, the utility model is taked following technical scheme: a kind of core lock, comprise lock body and the expansion link that is installed on the described lock body, and expansion link is provided with dead bolt, it is characterized in that at least two lock cores that are used to stir described expansion link are installed on the described lock body, and be described lock core configuration key.The technical program is provided with the lock core of a plurality of mutual interlocks on lock body, be generally two to three, when only in each lock core, all inserting correct key, and could rotational lock core.As long as do not insert correct key in one of them lock core, then this lock core self can not rotate, and this lock core matches with expansion link, causes whole expansion link to work, the failure of unblanking.Therefore, the lawless person need crack a plurality of lock cores simultaneously when skilled unlocking, increased unlocking difficulty undoubtedly, has prolonged uncaging time.

Offer two lockholes on the described lock body, in lockhole, dispose locking bar, described expansion link comprises first expansion link and second expansion link that is directed in the described lock body, described dead bolt comprises first dead bolt be located on first expansion link and is located at second dead bolt on second expansion link, and described first dead bolt and second dead bolt are respectively to should two lockholes and be provided with the locking structure that cooperates with described dead bolt on described locking bar.

Described lock core is provided with shifting block, and described expansion link is provided with allocating slot.

Described first expansion link and second expansion link stack together, and at least one the end in both is provided with step, are equipped with elastic component between this step and another expansion link, and it is flexible back and forth to utilize this elastic component to keep expansion link.

Have the vertical through holes that is used for interspersed locking bar on the described lock body.Can directly locking bar be inserted in the vertical through holes after the release, be difficult for skidding off, be easy to carry.

The beneficial effects of the utility model are embodied in: the lockset of traditional monolock cored structure is improved to the connection core lock with a plurality of lock cores, after only in all lock cores, inserting correct key, could unblank smoothly, as long as there is a lock core not to be cracked, the lawless person just can not realize unblanking, significantly promote the theftproof performance of lockset, increased the difficulty and the time of skilled unlocking.

The specific embodiment

A kind of core lock as Figure 1-3 mainly is made of lock body 1 and the expansion link that is installed on the lock body 1, and expansion link is provided with dead bolt.Expansion link comprises and is directed at the first expansion link 2A and the second expansion link 2B in the lock body 1 and that stack together that dead bolt comprises the first dead bolt 3A that is located at the first expansion link outboard end and is located at the second dead bolt 3B of the second expansion link 2B outboard end.At least two lock cores 4 that are used to stir expansion link are installed on the lock body 1, and are lock core 4 configuration key 5.The inner of lock core 4 is provided with shifting block 8, and expansion link is provided with the allocating slot 9 that matches with shifting block 8.Offer two lockholes 6 on the lock body 1, configuration locking bar 7 in lockhole 6, and the first dead bolt 3A and the second dead bolt 3B are respectively to should two lockholes 6 and be provided with the lock groove that cooperates with dead bolt on locking bar 7.At least one a end of two expansion links is provided with step 10, is equipped with elastic component 11 between this step 10 and another expansion link.Also have the vertical through holes 12 that is used for interspersed locking bar 7 on the lock body 1.

All insert correct key in all lock cores after, rotate one of them lock core again, first expansion link and second expansion link drive first dead bolt and the inside indentation of second dead bolt respectively, and the lock groove on dead bolt and the locking bar is broken away from mutually, realize unblanking.As long as do not insert correct key in one of them lock core, then this lock core self can not rotate, and the allocating slot that has on the shifting block of this lock core the inner and the expansion link cooperatively interacts, and causes the whole expansion link can't indentation, the failure of unblanking.Therefore, the lawless person need crack a plurality of lock cores simultaneously when skilled unlocking, increased unlocking difficulty undoubtedly, has prolonged uncaging time.
