Description

Safety lock

Affiliated technical field:

The utility model belongs to commodity, particularly be many keys could open use safety lock more.

Background technology:

The purposes of lock is very important in people's life, various in style, different purposes and effect are arranged, prosperity along with science and technology, the raising of life, demand is more, family needs door lock, factory needs the workshop door lock, the lock that armory wants several people to open, the lock that financial department needs two people just can open, the lock that some special sector also needs three people or more people could open together, but old way will lock several locks simultaneously, and is multifarious, unbecoming, effect is also undesirable, even the safety cabinet safety lock also can be utilized a lot of modes and decode, open, so used lockset is promptly inconvenient, also unreasonable, theftproof is also poor, and the patent 03271543.9 " cylinder lock " of application in I also is " concentric lock " that can only two people could open with key simultaneously on August 22nd, 2003, and the safety lock that many keys of the more people of needs could be opened is just rare.

Summary of the invention:

Order of the present invention provides and a kind ofly can be designed to more than 1 with safety cabinet, national treasury door and some other special local use, manyly uses safety lock to what different separately keys could be opened more.

It is the regulation that has adopted the magnetic cylinder lock in the 73-94 of Ministry of Machine-Building Industry of the People's Republic of China (PRC) file that the purpose of this utility model realizes, in conjunction with existing safety lock, lock, magnetic lock and other locks with handles, with its advantages, be bold in innovation, join handle attractive in appearance on main lock core, increased the branch lock core again around main lock core, branch lock core of every increase just mates a new key, it is Trinitarian to have formed sign indicating number, lock, hand, and antitheft parameter is up to the 20 novel safety locks of recalling; Specific design is as follows: safety lock is made up of lock body, lock core, pellet shot from a slingshot, pellet shot from a slingshot hole, key, keyhole, is provided with main lock core and at least 1 branch lock core in lock body, and each divides lock core parallel respectively being located at around the main lock core; The trunk portion branch of handle is located in the inner chamber of main lock core, and annular groove is established on the outer wall border in handle cylinder lower end, and groove and main lock core and lock body laterally are provided with through hole, near groove the inner the main lock core lock is housed in the through hole, and the outer end is provided with spring in the through hole; Each divides the lock core lower end by horizontal code column of double-screw bolt (off-centre) link joint, in the movable groove that inserts on the main lock core outer wall lower end of the code column other end.

Advantage of the present utility model is clearly: the principle of the utility model safety lock has adopted the regulation of the magnetic cylinder lock in the 73-94 of Ministry of Machine-Building Industry of the People's Republic of China (PRC) file, lock in conjunction with safety cabinet lock and the manual safety that use the existing market, the structure of lock with handles, with three's advantages, saved the combination disk of safety lock, handle, handle attractive in appearance is joined in innovation on main lock core, around main lock core, increased the branch lock core again, branch lock core of every increase just mates a new key, formed sign indicating number, lock, hand is Trinitarian, and antitheft parameter is up to the 20 novel safety locks of recalling; This lock divide lock core establish several all can, every many one just increases a new key, just improves confidentiality, cost is not high, processing is simple, easy to use, safe and reliable, need not special equipment can realize, is easy to promote, social benefit and economic benefit are unlimited.

Fig. 2 is that master of the present utility model looks generalized section

Fig. 3 is an elevational schematic view of the present utility model

1 is the lock body magnetic marble among the figure, the 2nd, and lock core magnetic marble, the 3rd, minute lock core keyhole, the 4th, minute lock core, the 5th, lock body, the 6th, handle, the 7th, main lock core, the 8th, pellet shot from a slingshot hole, the 9th, bolt, the 10th, code column, the 11st, connector, the 12nd, centring ring, the 13rd, minute lock key, the 14th, key magnetic marble, the 15th, main lock key, the 16th, code hole, the 17th, limited bolt, the 18th, spring, the 19th, drive sleeve, the 20th, annular groove.

The specific embodiment:

By accompanying drawing as can be known, the utility model safety lock has concentrated their advantages to design in the structure of having scrutinized existing various locksets, its profile can be circular, oval, polygonal, in same lock body 5, main lock core 7 is the heart therein, divides lock core 4 parallel peripheral around main lock core 7; Each minute, lock core 4 structure collectivities were similar, but main lock core 7, divided the magnetic marble 2 in the lock core 4 to mate different with magnetic patch on dividing lock core key 13 separately; Can set up the number of branch lock core as required; Handle 6 tops are handle, the shape that is fit to hold: wheel shape, profile of tooth, clavate, abnormity all can, its underpart is the hollow cylindricality, the hollow place is branch lock keyhole 3, establish the pellet shot from a slingshot hole in its cylindrical body respectively, its pellet shot from a slingshot hole communicates with pellet shot from a slingshot hole in the adjacent main lock core body 5 respectively, simultaneously with minute lock key on magnetic patch on same horizon.

By finding out also among the figure that so-called main lock core 7 also can claim drive sleeve 19, because containing pellet shot from a slingshot, handle 6 bottoms also play the main lock core effect, this part structure is different with the common spring lock, this part is: handle 6 hollow core are the keyhole of main lock core key 15, handle 6 bottoms (playing the main lock core effect) are sleeved in the main lock core 7 (being main lock core drive sleeve 19), handle 6, every row's pellet shot from a slingshot hole communicates in the main lock core 7, establish magnetic marble in the pellet shot from a slingshot hole respectively, the magnetic patch that on the main lock core key 15 there is iron chains, when inserting keyhole, each magnetic patch is on the same horizon with pellet shot from a slingshot hole, both sides respectively.

According to design typification lock body 5, on type lock body 5, process the main lock core hole, divide lock core hole; Reprocess out spacing keyhole, limited bolt 17, annular groove 20 and code column 10, the code hole 16 of main lock core 7, branch lock core 4, pellet shot from a slingshot hole 8 and adapted, system is allotted main lock core key 15, is divided lock key 13, in pellet shot from a slingshot hole 8 separately, add magnetic marble 1,2 then respectively; In through hole, add spring 18, limited bolt 17; Carry out integral body again by dress, debugging; During unlatching, with dividing lock key to open the branch lock respectively, when unblanking, rotate set angle (can be designed to password) and make code column 10 break away from groove code hole 16 earlier with the branch lock key; At last, open this lock with main lock core key 15 again.

Be magnetic lock among the utility model figure, as making cylinder lock entirely into, magnetic marble changes or non-magnetic marble in the pellet shot from a slingshot hole, and key changes common different teeth key into, can produce similar many key operated safety lock equally.

The utility model need not special equipment with the administrative staff and can realize.
