Description
Technical field
The invention belongs to lock technology field, and in particular to a kind of anti-lock cylinder of mortise and tenon type.
Background technology
American Yale-Lin Nasi inventions in 1848 adopt the spring lock of cylindrical pin, and spring lock is also known as cylinder lock with balls, pearl
Lock, pearl lock, snap lock or pin tumbler locks, are a kind of modal lock structures.Principle is the cylinder for using multiple differing heights
Shape part (referred to as snap, pellet or pearl), pins lock core.When correct key is put into, each snap is pushed to identical height, lock
Core is just released, and at present, this kind of structure is widely used in the world.The structure of modern spring lock has new development again, occurs double
To, three-dimensional, four-way pellet, various structures such as female pellet, and plane, two-sided, multiaspect, double-row double surface, multiple rows of multiaspect pellet knot
Structure and combination billiards structure so as to greatly improving the security performance of lock, make the numbering of lock from original 2500 kinds by " to ",
The change in " face " reaches million kinds.But drawback is more and more obvious, mainly there are three aspects：Expose and impulse stroke pellet end
Short, pellet can be touched directly by foreign body, easily be opened (aciculiform device is unlocked, and " hitting spoon " unlocks) by technology；Non- lock key all can enter
Enter lock core, easily cause that key is mutually opened and key tooth not etc. is not mutually opened；Key can be configured arbitrarily, bitting process is simple, with one
The key mould of spring lock, set up tinfoil just can easily open the door in ten seconds；Violence is unlocked, and pellet is twisted into two parts, it is easy to open
Lock.
The content of the invention
The technical problem to be solved is the shortcoming for overcoming existing spring lock, there is provided a kind of reasonable in design, knot
The anti-lock cylinder of mortise and tenon type that structure is simple, safety coefficient is high.
Solving the technical scheme that adopted of above-mentioned technical problem is：The bottom of front lock core lid is machined with keyhole, medial wall
On be machined with the first groove a, be machined with the second groove b in the bottom of the first groove a, be provided with key in keyhole, install in the first groove a
The inner bottom part center for having pellet, front lock core lid is installed with front internal cylinder pad, and the geometry of front internal cylinder pad is circle
Cylindricality, processes the 5th groove e on cylindrical outer surface, internal lock core body is placed with front lock core pad, in internal lock core body bottom disc
The heart is machined with lock core shaft, and lock core shaft end is processed into cylinder of the diameter less than lock core shaft, groove is machined with cylinder, in internal lock core body
The side of bottom disc is machined with clematis stem groove f, and rear internal cylinder pad, rear lock core lid are sequentially installed with internal lock core body lock core shaft,
Afterwards internal cylinder pad is fixedly mounted on rear lock core lid, and rear internal cylinder pad side is machined with the 7th groove g, the medial wall of rear lock core lid
On be machined with and the groove c of the first groove a identicals the 3rd, be machined with and the groove d of the second groove b identicals the 4th in the bottom of the 3rd groove c,
Two groove b and the 4th groove d constitute spring groove, and spring is provided with spring groove, and the first groove a and the 3rd groove c constitutes bullet groove.
The geometry of pellet of the present invention is F shapes, and long-armed back is machined with boss, and the number of pellet is 2~12 energy deciles
The number of circumference；Described the first groove a, the second groove b, the 5th groove e, clematis stem groove f, the number of the 7th groove g and pellet
Number is identical；The thickness of described the first groove a, the second groove b, the 5th groove e, clematis stem groove f, the width of the 7th groove g and pellet
It is identical；The height of described internal lock core body bottom disc is identical with the distance between the galianconism of pellet two.
The number of the pellet of the present invention is 12.
Because the present invention adopts many pellet arrangement modes, the probability for hitting spoon unlocking is reduced, because front lock core lid and rear lock
Core cap is connect with gluing, if being unlocked using aciculiform device can lose part sense of touch, and pellet number is more, is unlocked difficult, safety coefficient
It is high.
