Description
Technical Field
The invention relates to the field of locks, in particular to a coded lock.
Background
At present, fingerprint door locks are widely applied to entrance doors, but due to the fact that a battery is adopted for driving, electronic products are in electronic failure or the battery is usually exhausted after the electronic products are used for a period of time, at the moment, the fingerprint locks can only be unlocked by using a standby mechanical key, people often cannot carry the standby mechanical key to go out, when the mechanical lock part of the fingerprint locks needs to be opened by using the standby mechanical key, the situation that users are locked outside the doors is caused, only professionals can be found to charge or unlock the door locks, and therefore a password lock which is installed on the fingerprint locks and does not need to be unlocked by a key and has good reliability is needed to replace a standby mechanical unlocking module when the fingerprint locks.
Disclosure of Invention
The technical problem to be solved by the present invention is to address the above-mentioned shortcomings of the prior art,
a combination lock is provided.
In order to achieve the above purpose, the present invention provides the following technical solutions: the utility model provides a trick lock, includes that one end is equipped with the lock box of open slot, its characterized in that: the unlocking mechanism comprises an unlocking box, one side of the unlocking box is provided with a stirring block, the other end of the unlocking box, which is opposite to the stirring block, is provided with a first linkage block driven by the stirring block, at least one group of spaced second linkage blocks are arranged in the vertical direction of the first linkage block, the other end of the second linkage block, which is opposite to the first linkage block, is connected with an unlocking password disc which is rotatably arranged, the unlocking password disc comprises a gear disc, the gear disc is provided with a password stirring disc, the other end of the gear disc is provided with an unlocking block, the second linkage block and the unlocking block are positioned on the same plane, the circumference of the password stirring disc is provided with at least 10 password marks, one password mark is an unlocking mark, the unlocking mark and the unlocking block are positioned on the same vertical plane, and a pressing type unlocking mark modifying mechanism which can modify the unlocking mark when the second linkage block and the unlocking block are propped against each other is arranged in the unlocking password disc.
By adopting the technical scheme, the traditional disc type coded lock is not capable of modifying the codes, the codes are set in a certain range when leaving the factory, for example, the unlocking rotary disc of the safe can be modified only in a limited range, and the codes can be modified at will by arranging the pressing type unlocking identification modifying mechanism.
The above-mentioned one kind of trick lock may further set up as: the push type unlocking mark modification mechanism comprises a linkage disc, one end of the linkage disc penetrates through the other end of the gear disc and is connected with the password toggle disc, a first linkage tooth is circumferentially arranged at one end of the linkage disc, which faces the unlocking block, a second linkage tooth is arranged at the corresponding position of the first linkage tooth, a limiting convex shaft extending towards the unlocking block is arranged on the linkage disc, a limiting notch corresponding to the limiting convex shaft is arranged on the unlocking block, and a linkage disc reset mechanism is arranged between the first linkage tooth and the limiting convex shaft.
By adopting the technical scheme, as the linkage disc is provided with the first linkage teeth, the gear disc is correspondingly provided with the second linkage teeth meshed with the first linkage teeth in the circumferential direction, when the password stirring block is rotated, the password stirring block is fixedly arranged in the linkage disc, the linkage disc is meshed with the gear disc, so that the whole unlocking password disc rotates, the first linkage block is provided with the linkage groove, when unlocking blocks in all unlocking password discs are propped against the second linkage block, the whole unlocking mechanism can be unlocked, the unlocking mark and the unlocking block are in the same vertical plane, the unlocking password disc is in an unlocking state when the unlocking password disc is rotated to prop against the second linkage block, one end of the second linkage block is positioned in the linkage groove of the first linkage block, the other end of the second linkage block is forced to move in the gear disc, and the password stirring disc is pressed downwards at the moment, so that the limiting convex shaft on the linkage disc is dropped into the limiting notch in the unlocking block, and the first linkage teeth on the linkage disc are separated from the second teeth on the gear disc, and the linkage disc can be reset when the linkage disc rotates under the stirring password disc to independently, and the linkage disc can be reset to change the password disc, and the linkage disc can be reset to change the state when the linkage disc rotates, and the password disc can be reset and the linkage disc can be simultaneously changed.
The above-mentioned one kind of trick lock may further set up as: the linkage disc reset mechanism comprises a reset spring, a containing cavity is formed between the limiting protruding shaft and the first linkage tooth of the linkage disc, one end of the reset spring is abutted against the other end of the containing cavity and against the unlocking block, and one end, far away from the second linkage block, of the unlocking block is provided with an unlocking block limiting mechanism.
By adopting the technical scheme, the reset spring with the diameter larger than that of the limiting convex shaft and the limiting notch is arranged in the accommodating cavity, the linkage disc is reset through the reset spring after the unlocking mark is modified, the unlocking block limiting mechanism arranged at one end of the unlocking block, which is far away from the second linkage block, can effectively place the unlocking block to be exposed to the unlocking password disc too much, and prevent certain professionals from cracking the password lock by observing the position of the unlocking block.
The above-mentioned one kind of trick lock may further set up as: the unlocking block limiting mechanism is a limiting lug arranged on the unlocking block, and one end of the limiting lug is provided with an arc notch matched with the limiting protruding shaft.
By adopting the technical scheme, the limit protruding block is arranged as close to the limit protruding shaft as possible, so that the unlocking block is prevented from being excessively exposed out of the gear disc, and a professional is prevented from cracking by observing the position of the unlocking block on the gear disc.
The beneficial effects of the invention are as follows: the push type unlocking identification modification mechanism is ingenious in structure and greatly improves the anti-cracking rate, and the technical scheme provided by the invention can replace the mechanical unlocking of the fingerprint lock, can be applied to a door and a draw-bar box unlocked by a traditional mechanical key or other fields requiring the use of a disc type coded lock, and is strong in universality.
The invention is described in further detail below with reference to the drawings and examples.
