Abstract

The invention relates to a tumbler idle digital lock and a comb-shaped invisible key matched with the same. The tumbler idle digital lock comprises a shell, an idle lock cylinder, a lock cylinder bolt, a chute, a plug, a spring and the invisible key, wherein the idle lock cylinder and a round lock cylinder are embedded into the shell; holes on the idle lock cylinder and the round lock cylinder correspond to holes on the shell; a round groove is formed in the shell, the idle lock cylinder and the round lock cylinder; a thimble, a digital tumbler, the lock cylinder bolt, the spring and the plug are arranged in the round groove in turn; and a lock head shell is provided with a key hole matched with the invisible key. The invention also relates to a spring plate idle digital lock, wherein the lock cylinder is platy, the spring is spring plate-shaped, and the invisible key is card-shaped. The lock has a novel structure and high practicability, the key hole and the lock head shell can independently idle, the invisible key is secret and safe and has attractive appearance, the lock can be effectively prevented from being unlocked by all illegal tools or illegally technically unlocked, the lock cylinder cannot be controlled by external force, and the lock has anti-theft and anti-damage capability, a simple structure, low cost and a wide application range.

Description

Idle running combination padlock and associated stealthy key

Technical field

The present invention relates to a kind of idle running combination padlock (spring type, shell fragment type), associated stealthy key (comb type, card-type).

Background technology

The mechanical lock of Chu Xianing in the market, though it is various in style, but lock core structure is mostly basic identical, this class lock pin pellet shot from a slingshot height is differential too little, use instruments such as master key, electric drill, vibration lockaid gun to turn round illegal unlatching by force as the lawless person, all be easy to open, this class lock key has been subjected to limitation, the repetitive rate height.At ordinary times the key nude outside, it is dangerous to divulge a secret easily, causes the serious consequence of stolen property easily.

Summary of the invention

It is differential too little that purpose of the present invention will be broken through the lock core marble height exactly, and key repetitive rate height is turned round by force, these difficult problems of instrument such as brill, Qiang Zhen and illegal property technical opening by force easily.

The purpose of the stealthy key of the present invention will promptly be maintained secrecy exactly, safety, and is attractive in appearance again.

Technical scheme of the present invention is achieved in that the associated stealthy key of a kind of idle running combination padlock (spring type) (comb type), it comprises housing, idle-run lock pin, the lock core bolt, chute, plug, spring and stealthy key, idle-run lock pin, circular lock core is inserted in the housing, idle-run lock pin, hole on the circular lock core is corresponding with the hole on the housing, at housing, idle-run lock pin, have circular trough in the circular lock core, in circular trough, be provided with thimble successively, digital pellet shot from a slingshot, the lock core bolt, spring and plug, have the keyhole that matches with stealthy key on the tapered end shell, keyhole and tapered end shell can independently dally.

Another kind of technical scheme of the present invention is: idle running combination padlock (shell fragment type), and lock core groove 3 is with shown in Fig. 6, (12), and pellet shot from a slingshot is a sheet sheet shape, spring is a shell fragment shape, the pellet shot from a slingshot of idle-run lock pin the inside is a double headed roller point Long Circle pellet shot from a slingshot, and stealthy key is a card-shape, and principle and function are same as in figure 1.

Advantage of the present invention is: novel structure, practical, keyhole, tapered end shell can independently dally, can prevent effectively that all illegal instruments from opening, particularly can prevent turning round by force, anti-ly bore by force, against shock and illegal property technical opening, antitheft, anti-damage ability is strong, it is the lock of truly illegally not opening, and simple in structure, cost is low, and the scope of application is wide.

The specific embodiment

As Fig. 1,2,3, shown in 4, the associated stealthy key of a kind of idle running combination padlock (spring type) (comb type), it comprises housing 5, chute 10, lock core bolt 4, plug 1, spring 2 and stealthy key 15, circular lock core 6, idle-run lock pin 7 is inserted in the housing 5, circular lock core 6, hole on the idle-run lock pin 7 is corresponding with the hole on the housing 5, at circular lock core 6, idle-run lock pin 7, have circular trough 3 in the housing 5, in circular trough 3, be provided with thimble 9 successively, digital pellet shot from a slingshot 8, lock core bolt 4, spring 2 and plug 1, have the keyhole 12 that matches with stealthy key 15 on tapered end shell 11, keyhole 12 can independently dally with tapered end shell 11.

The stealthy key of the present invention is made simple, a kind of comb shape Fig. 4, and a kind of card-shape Fig. 8, refers to thruster 14, stealthy key 15, spring at critical piece key shell 13 Or (magnet) is formed.Thumb is pinned and is referred to the stealthy key 15 of thruster 14 releases, and the rear spring of loosing one's grip is rebounded key.Stealthy key 15 and thimble 9 and digital pellet shot from a slingshot 8 are programmed in advance before assembling, with manually closing the door, open the door automatically with spring, and stealthy key 15 inserts lockhole 12 and can open.Open as illegal insertion, because of lock core bolt 4, digital pellet shot from a slingshot 8, thimble 9 also can be stirred, but its porous one, 4 up-downgoings of lock core bolt are apart from reaching 20mm, and stealthy key 15 convex-concave 0.5-20mm do not wait.Calculate according to the mathematics permutations and combinations, key 1,500 ten thousand is just repeating once, and as uncaging time one minute once, because of it is the also need up to ten thousand hours of machinery, so can effectively prevent all illegal instrument and technical unlockings, the anti-theft and anti-damage ability is strong.

Another kind of idle running combination padlock (shell fragment type) embodiment of the present invention is, shown in Fig. 5,6,7,8, lock core groove 3 is shown in Fig. 6, (12), digital pellet shot from a slingshot 8 is a sheet sheet type, spring 2 is the shell fragment type, and the digital pellet shot from a slingshot 8 in the idle-run lock pin 7 is double headed roller point Long Circle pellets shot from a slingshot, and stealthy key 15 is card-shapes, keyhole 12 can independently dally with tapered end shell 11, and principle and function are same as in figure 1.
