Abstract
The invention discloses a mechanical password lock with a device for preventing an unlocking password from being tested. The lock is formed by additionally arranging an auxiliary device with rubber wheels on a main shaft of a conventional rotary table type mechanical password lock; the lock moves along with an insertion plate of a password groove; before the insertion plate nearly comes into contact with rotary tables on the rotary table type mechanical password lock, a pair of rubber wheels on the device comes into contact with each rotary table on the rotary table type mechanical password lock and forcedly prevents each rotary table from individually rotating, so that the aim of preventing other people from testing the password is achieved.
Description
Technical field
The present invention relates to a kind of coded lock, is a kind ofly be provided with the mechanical code lock preventing unlocking cipher device being tested specifically.
Background technology
Now, coded lock is widely applied.Rotary disk type mechanical coded lock in coded lock widely uses in safety cabinet, file cabinet, security door, warehouse gate and mechanical jam mechanism.The advantage of this coded lock is without key, without power supply, without battery, simple to operate; Owing to being full mechanical and structure is simple, can bear quite severe external environment condition, reliably solid, the scope of application is wide.But rotary disk type mechanical coded lock is easier to be tested out code data by the experienced person that illegally do not unblank, and therefore there is more serious potential safety hazard.
Summary of the invention
For the deficiency that prior art exists, the invention provides and be a kind ofly provided with the mechanical code lock preventing unlocking cipher device being tested.
The object of the present invention is achieved like this: be a kind ofly provided with the mechanical code lock preventing unlocking cipher device being tested, comprise lock main body, annex, slide block, password groove inserted block, spring leaf, rubber tire, runner, rotating shaft, described lock main body and rotating shaft cover weld together, described runner and rotating shaft are an entirety, rotating shaft is enclosed within the middle of rotating shaft cover, annex is sleeved on rotating shaft and puts, described annex is provided with chute and locating piece, described slide block is provided with password groove inserted block, password groove inserted block both sides are provided with spring leaf, and the front end of spring leaf is provided with rubber tire; Nut, turn, lower screens packing ring, lower driven combination disk, middle screens packing ring, upper driven combination disk, upper screens packing ring, initiatively combination disk, be sleeved on rotating shaft successively and put.When described password groove inserted block moves forward, always lower driven combination disk, upper driven combination disk and active combination disk is touched prior to password groove inserted block with the rubber tire of its interlock, password groove inserted block is mobile when touching lower driven combination disk, upper driven combination disk and active combination disk forward, forces lower driven combination disk, upper driven combination disk and active combination disk not to rotate separately with the rubber tire of its interlock.
Adopt technical solution of the present invention, there is following beneficial effect:
The present invention is that mechanical rotation plate cipher lock adds anti-password test annex, without the need to changing the structure of existing machinery turntable coded lock.Be connected with a pair rubber tire above password groove inserted block is arranged on by this annex, rubber tire always touches rotating disk prior to password groove inserted block, when password groove inserted block can touch rotating disk, rubber tire has been urged to all rotating disks, and any one rotating disk can not be rotated separately.The present invention make secret service in the past, locksmith or robber detect rotating disk socket one by one with password groove inserted block to crack the method for mechanical turntable coded lock password entirely ineffective, greatly can improve the security performance of mechanical rotation plate cipher lock.
Accompanying drawing explanation
Fig. 1 is assembling drawing of the present invention;
Fig. 2 is stereogram of the present invention (password groove inserted block does not touch the state of rotating disk);
Fig. 3 is stereogram of the present invention (close to rotating disk, rubber tire contacts the state of rotating disk to password groove inserted block);
Fig. 4 is stereogram of the present invention (when password is correct, password groove inserted block inserts the state of rotating disk);

Detailed description of the invention
Below, the invention will be further described in conjunction with the accompanying drawings and embodiments.
Fig. 1-Fig. 4 is one embodiment of the present of invention, as shown in the figure, a kind ofly be provided with the mechanical code lock preventing unlocking cipher device being tested, comprise lock main body 30, annex 10, slide block 20, password groove inserted block 21, spring leaf 22, rubber tire 23, runner 31, rotating shaft 32, described lock main body 30 is overlapped 33 with rotating shaft and is welded together, described runner 31 is an entirety with rotating shaft 32, rotating shaft 32 is enclosed within the middle of rotating shaft cover 33, annex 10 is sleeved on rotating shaft cover 33, described annex 10 is provided with chute 11 and locating piece 13, described slide block 20 is provided with password groove inserted block 21, password groove inserted block 21 both sides are provided with spring leaf 22, the front end of spring leaf 22 is provided with rubber tire 23, nut 40, turn 41, lower screens packing ring 42, lower driven combination disk 50, middle screens packing ring 43, upper driven combination disk 60, upper screens packing ring 44, initiatively combination disk 70, be sleeved on rotating shaft cover 33 successively.When described password groove inserted block 21 moves forward, always lower driven combination disk 50, upper driven combination disk 60 and active combination disk 70 is touched prior to password groove inserted block 21 with the rubber tire 23 of its interlock, password groove inserted block 21 is mobile when touching lower driven combination disk 50, upper driven combination disk 60 and active combination disk 70 forward, be urged to lower driven combination disk 50, upper driven combination disk 60 and active combination disk 70 with the rubber tire 23 of its interlock, made it not rotate separately.What the present invention can make secret service in the past, locksmith or robber adopt detects with password groove inserted block the method inefficacy that rotating disk socket cracks mechanical turntable coded lock password one by one.
The above embodiment of the present invention is the exemplary embodiment for illustrating cited by the present invention, instead of to the restriction that embodiments of the present invention are done.By the embodiment of the present invention prompting the obvious variation pattern of amplifying out be still in the scope of the present invention.
