Description
Art
The present invention relates to a kind of lockset, particularly a kind of mechanical lock without pin tumbler and private key.
Background technology
At present, the mechanical lock opened using key be by lock body and installed in vivo rotatable lock core group
Into being provided with the keyhole for inserting key on lock core, multigroup pellet and spring, every group of pellet be provided with lock core and lock body
It is made up of two pellets different in size.Pellet and spring are enclosed in lock core and lock body using lead sealing in the side of lock body
It is interior, with its it is supporting be provided with corresponding pit on the key, after key inserts keyhole, pellet just contacts with corresponding pit,
Corresponding pellet moves axially to diverse location along pellet, makes two pellets in multigroup pellet of installation in lock core and lock body
Contact surface, be placed exactly on the contact surface of lock core periphery and lock body endoporus, key turns band movable lock core rotate will lock open.
To improve the security of mechanical cylinder lock, it is common practice to increase the quantity of pellet group and change the shape in key section, such as
There are a shapes such as " one " font, Y-shaped, " ten " font, crescent in the section of key at present, the quantity of pellet group in 4-12 groups,
So on the one hand add spring lock number of parts and processing, assembling difficulty, improve processing cost, on the other hand due to
The operation principle of spring lock causes its security not high, is very easy to be opened by criminal.
Applicant is in a kind of on 2 1st, 2011 patent of invention for having applied for entitled " duplex safety mechanical lock ", Granted publication
Number CN201963074U.It which disclose one kind and lock core bluff piece added between rotor lock core and nail lock body, pass through lock
Core bluff piece closes the keyhole on rotor lock core, can effectively prevent other instruments in addition to private key from entering in keyhole,
The illegal phenomenon for opening lock occurs.
The content of the invention
It is an object of the invention to provide a kind of number of parts is few, the simple in construction, mechanical lock without pin tumbler that has a safety feature and
Private key.
The technical scheme is that：A kind of mechanical lock without pin tumbler, including lock body and the rotatable lock in lock body
Core, lock core bluff piece is installed in lock body and lock core, it is characterised in that lock core is "T"-shaped multi-diameter shaft, in "T"-shaped multi-diameter shaft
Big cylinder on be provided with key hole, and big cylinder matches with the shoulder hole on lock body, the small cylinder of "T"-shaped multi-diameter shaft
Lock body lower end is stretched out in lower end, and is positioned by axial direction positioning device, the annular cavity formed between small cylinder and lock body
It is interior, key barrier plate is fixed with, the elongated slot to match with key outline is provided with key barrier plate.
Above-mentioned axial direction positioning device is axle spring collar or the pad and fixing screws in the installation of lock core lower surface.
Angle between the center line of above-mentioned key hole and the center line of key barrier plate is 90-180 degree.
Mechanical lock without pin tumbler private key, including the shank of the key and key body, it is characterised in that in key body and above-mentioned key
Jack matches, and the through hole to match with jam plate, relative two of key body are provided with key body top and above-mentioned jam plate correspondence position
The outline of side is curved surface or pit, and with the elongated slot Internal periphery phase on the key barrier plate in above-mentioned mechanical lock without pin tumbler
Match somebody with somebody, the lower end of key body is wedge shape.
Technical scheme make use of the matching relationship and structure between the lock body and lock core of existing machinery spring lock,
But there is annular cavity between lock body internal cylinder and lock body, one piece of key barrier plate is installed in annular cavity, key is inserted
Angle between the center line in hole and the center line of key barrier plate is equal to or more than 90 degree, is installed in the radial direction of key hole
There is lock core bluff piece.In normal state, key hole is closed by lock core bluff piece, need to be inside by lock core bluff piece when illegal unlock
Push away, now lock core bluff piece just pins lock core and lock body, makes not relatively rotating between lock core and lock body, thus can effectively prevent
Only illegal unlock, improve the security of lock.And when the key to match with lock is inserted, lock core bluff piece is placed exactly on the key
In the through hole to match with lock core bluff piece, after key turns are equal to or more than 90 degree, key body will contact with key barrier plate, when
When the outline of key body matches with the elongated slot on key barrier plate, key, which may continue to rotation startup opening mechanism of lock spring bolt, to be locked
Open, when outline and the elongated slot not timing on key barrier plate, the key of key body will be unable to be rotated further, lock can not just be beaten
Open.Because key barrier plate is located in lock body, and in the position that key hole can not be seen or visit, there is lock core bluff piece will again
Key hole is closed, and so can not illegally be opened using existing means.Because the part of the technical program only has 7-10
It is individual, the number of parts of existing mechanical cylinder lock is considerably less than, production is low with assembly cost, and security is good.Outside due to key
Profile is engaged with the elongated slot on key barrier plate, and the repetitive rate that small change between the two can solve to lock at present is high
The problem of.
