Description
Technical field
The utility model relates to a kind of lockset and is applicable to the key of this lockset, that is: a kind of concealed rotary locking cylinder and unlocking key.
Background technology
Popular side column pellet class lockset in the market, also claim " atom " class lockset, be all adopt external force to promote or rotate the lock core that contains key hole and directly or indirectly realize and unblanking, the key hole of this anti-theft lock core has various shape as " once ", " cross ", " semi arch ", " plum blossom ", " cylinder " etc.Theftproof lock entire body is iron and steel manufacture, and theftproof lock theftproof performance is fine outwardly, and market is also very universal.But in actual life, practical this lock theft case occurs often, and lock core is destroyed lock core with go into operation by force tool or Miniature electric drill by lawless person, and several seconds just can technical opening.Because it is exactly that lock core and key hole expose that this theftproof lock has a kind of very large technical design defect, key hole exposes outside, and the mode of unblanking is to rotate key unlocking after key bit is inserted to the key hole of lock core.So the very large space of unblanking is provided to professional technique or the violence person of unblanking, causes its theftproof performance poor.
In order to address the above problem, the applicant in Chinese invention patent application publication No. CN 103397820 A, discloses a kind of Hiding security lock core and unlocking key on November 20th, 2013.It comprises that lock core, locking drive bolt and unlocking key; Dovetail groove is opened in lock core bottom, and inside be arranged in parallel a wide strip through-hole and a fillet shape blind hole, form partition wall one between this two hole; In fillet shape blind hole, there are marble hole and side column pellet; It is the microscler steel bar with dovetail flange that locking drives bolt, is provided with lower pellet blind hole, lower side column pellet and marble spring on the dovetail flange surface of corresponding lock core marble hole site; Unlocking key is a batten that is down " U " shape, and batten is key shank part on one side, and another limit is the shank of the key part.Key hole and remainder on this technical scheme lock core all can be hidden, and robber is had no way of doing it.No matter technical opening, the improper means such as tool, electric drill this lock of all not opening that goes into operation by force.But this technical scheme is only suitable for and uses the locking of dovetail groove to drive stud structure.
Utility model content
The purpose of this utility model is to provide a kind of concealed rotary locking cylinder and unlocking key, have theftproof performance good, be applicable to different rotary locking drive bolt.
In order to solve the problems of the technologies described above, the concealed rotary locking cylinder of one of the present utility model, comprises that lock core and rotary locking drive bolt; It is characterized in that: lock core is the square or cylindrical block that round tube hole is opened at middle part; Two the bar shaped ducts that width is different that be arranged in parallel, the inside of lock core; Wherein, wide bar shaped duct and the formation insert port that communicates before square or cylindrical block; The front end face of fillet shape duct and square or cylindrical block is obstructed; Between described wide bar shaped duct and fillet shape duct together with forming in lock core partition wall; Fillet shape has marble hole section in duct, has side column pellet in each marble hole; Described rotary locking drives movable cooperation of round tube hole of bolt and lock core, make rotary locking driving bolt relatively lock core rotate, realization is directly or indirectly unblanked; Drive on hitching post face and be provided with pellet blind hole corresponding with lock core marble hole site and that quantity is equal, the built-in post pellet of each pellet blind hole and marble spring at rotary locking; In the time that rotary locking drives bolt to forward on lock core locked position, all lock core marble holes and rotary locking drive pellet blind holes all on hitching post face just right, and the docking port place in every pair of hole always has post pellet or side column pellet to tack.
In the length of above-mentioned partition wall and fillet shape duct, the length of marble hole section is suitable, and has guide groove at lock core rear portion between wide bar shaped duct and fillet shape duct.
On above-mentioned lock core, there is the fixed installation part being connected with lock body shell.
The unlocking key of opening above-mentioned concealed rotary locking cylinder is a batten that is down " U " shape, and the width of batten and thickness are equal to or less than width and the height in the wide bar shaped duct on above-mentioned lock core; Different in size the causing of two parallel straight edges of batten; Its short-and-medium straight flange is key shank part, the dark wide high size correspondent equal in the fillet shape duct on the length and width of key shank part, thick size and lock core; Long straight flange is the shank of the key part, and the effective length of the shank of the key part handle bar is greater than the length of partition wall; Between two parallel straight edges of above-mentioned batten, form microscler gap, the width in microscler gap equals the width of lock core internal partition wall.
Compared with the prior art: one of advantage of the present utility model has guide groove at lock core rear portion between the wide bar shaped duct of lock core and fillet shape duct, play unlocking key guide effect, and be conducive to shorten the length of unlocking key.Two of advantage of the present utility model is lock core is hidden in to the shell of tapered end or lock body or is mounted in a honorable plate, unlocking key turnover key channel and key hole opposite direction, and not on same straight line; Can't see Anywhere lock core parts from the shell of tapered end or lock body, thereby prevented that robber is by electric drill, the means such as tool, technical opening that go into operation are opened the object of this lock by force.Three of advantage of the present utility model is: the key shank part plug power thrusts of unlocking key is consistent with the shank of the key power thrusts, and the feel of unblanking is strong.Such structure, had both ensured the hidden of lock core parts dexterously, did not change again traditional custom of unblanking.Four of advantage of the present utility model is because lock core maintains static by the fixed installation part of connection and the shell of tapered end or lock body, all can be hidden in shell or be mounted in the panel of a body for opening with sliding part and the lock core of locking, as long as shell or the honorable plate of door are indestructible, tapered end just can be safe and sound.Rotary locking drives bolt can coordinate torsion joystick control unlocking mechanism to be made into the triggering draw bar of existing self-clutched machine door lockset, applying flexible.
