Problems solved by technology

Their two lock cylinders are arranged side by side. Usually, two keys are used to unlock the lock, which only increases the difficulty of technical unlocking, but it can still be cracked one by one. There are also the above-mentioned disadvantages of being easily unlocked by technology or violence.

Embodiment 1

[0028] The embodiment of the present invention will be further described below by taking the first lock cylinder and the second lock cylinder both using a pin mechanism as a password.

[0029] see figure 1 As shown, the lockset of the present invention is a double lock core structure, with a first lock core 11 and a second lock core 21, and the first lock core 11 uses the first pin mechanism 12 as a password to lock and decode the first lock core 11 , when the first pin mechanism 12 of the first lock core is locked, that is, the first pin mechanism 12 is locked between the first lock core 11 and the lock head body 10, the first lock core 11 cannot rotate. When the first pin mechanism 12 of the lock core is decoded, the first lock core 11 can be rotated under the condition of locking without other conditions; similarly, the second lock core 21 uses the second pin mechanism 22 as a password to lock the second lock. The core 21 is locked and decoded. When the second pin mechanis...

Embodiment 2

[0050] see figure 2 As shown, a double lock cylinder mutual control and decoding method of a lockset of the present invention includes:

[0051] First the password of the first lock core 31 (i.e. the first pin mechanism 32) is decoded, before the password decoding of the first lock core 31, the first lock core 31 limits the password of the second lock core 41 (ie the second pin mechanism). 42), the second lock core 41 limits the rotation of the first lock core 31;

[0052] After the password of the first lock cylinder 31 is decoded, the first lock cylinder 31 can be displaced but cannot be rotated;

[0053] When the first lock core 31 was displaced in place, the first lock core 31 released the restriction on the decoding of the password (i.e. the second pin mechanism 42) of the second lock core 41, while the second lock core 41 still restricted the first lock core. 31 rotations;

[0054] Then the password (i.e. the second pin mechanism 42) of the second lock core 41 is dec...

Embodiment 3

[0067] see Figure 3 to Figure 4 As shown, a double lock cylinder mutual control and decoding method of a lockset of the present invention includes:

[0068] First the password decoding of the first lock cylinder 51, before the password decoding of the first lock cylinder 51, the first lock cylinder 51 limits the decoding of the password of the second lock cylinder 61, and the second lock cylinder 61 limits the decoding of the password of the first lock cylinder 51. rotation of the core 51;

[0069] In this embodiment, the password of the first lock cylinder 51 adopts the rear key bar 52 and the first blade mechanism 53, and the rear key bar 52 can move up and down, and is stuck between the first lock core 51 and the lock head body 50 before decoding. During decoding, the rear key bar 52 is completely moved into the first lock core 51, and the first blade mechanism 53 controls the movement of the rear key bar 52 by cooperating with the decoding part (i.e. the key 60); similar...

Abstract

Disclosed in the invention is a dual-lock-pin mutual control and decoding method of a lockset. A first lock pin is decoded; before decoding of the first lock pin, the first lock pin limits decoding of a second lock pin and the second lock pin limits rotation of the first lock pin; after decoding of the first lock pin, the first lock pin can move but can not rotate. When the moving to a right place, the first lock pin lifts the limitation on the decoding of the second lock pin and a decoding inlet is in a local closing state, so that an abnormal unlocking tool can not enter the inlet; and the second lock pin still limits rotation of the first lock pin. And the second lock pin is decoded; and the first lock pin and the second lock pin can rotate together only after decoding of the second lock pin, thereby realizing unlocking. According to the method, on the basis of mutual control of the two lock pins, no condition is provided for technical unlocking logically, thereby improving safety of the lockset.

Description

technical field [0001] The invention relates to a lock, in particular to a double lock cylinder mutual control and decoding method of the lock. Background technique [0002] The most widely used in the existing various locks is the tumbler lock, and there are many deficiencies in various tumbler locks in actual use, and it is easy to be opened by people with a special-purpose dial lock tool. The unlocking method is very simple. The person who unlocks the lock uses the unlocking wire hook to dial the pins in the lock body and the lock cylinder to the mating surface of the lock cylinder and the lock body one by one, and then turn the lock cylinder to open the lock; After the key is inserted into the lock hole and shaken, the traces of the marbles are printed on the tin foil so that all the marbles fall on the mating surface of the lock cylinder and the lock head body, and then turn the lock cylinder to unlock; you can also use a toothed tool to hit or dial back and forth The ...
