Abstract
The utility model discloses a lock disk type mechanical cipher lock which relates to a machine in daily service. The utility model is provided with a cylinder lock core, a shifting disc, a cipher disc, a rotating handle and a lock rod. The utility model is characterized in that a cam is fixedly connected to the cylinder lock core, a clamping block which can be slid is arranged between the cam and the cipher disc, and the transversal profile of the contacting position of a shaft of the cipher disc and the clamping block is in the shape of a quadrangle. When the utility model reaches a locking position, a shaft of the shifting disc is pressed upwards by the cam, and the shifting disc can not be rotated freely. The utility model has the advantages that the utility model is locked reliably, the confidentiality of mechanical ciphers is strong, and the mechanical ciphers can not be deciphered.
Description
The utility model relates to daily machinery, is a kind of lock collar formula mechanical code lock that is used on the safe door, and it also can be used as the door lock of file cabinet and essential industry equipment.
At present, all adopt the disc type mechanical code lock on the general insurance cabinet door, this be locked into reach lock-bit after, dial still can freely rotate, this decodes the chance of this lock machine tool password with feel for the criminal, has accident potential.
The purpose of this utility model provides a kind of lock collar formula mechanical code lock, and it is when lock-bit, and dial is also locked, has eradicated above-mentioned accident potential.
The purpose of this utility model is to realize like this, lock collar formula mechanical code lock is provided with lock cylinder, dial, code-disc, turning handle and locking bar, it is characterized in that: be connected with cam on the lock cylinder, be provided with slidably fixture block between cam and the code-disc, code disk shaft is square by the cross section of fixture block contact position.
The utility model is to improve to form on disc type mechanical code lock basis, and characteristics are: locking is reliable, and dial is also locked during lock-bit, and the mechanical cipher strong security can not be decrypted.
Embodiment further describes below in conjunction with accompanying drawing, and Fig. 1 is a structural principle schematic diagram of the present utility model, Fig. 2 is the A-A face sectional view of Fig. 1, and Fig. 2 has shown lock cylinder, fixture block and the dial axle position relation behind the lock-bit.
Embodiment: with the lock collar formula mechanical code lock that is used for electric metering box is example, lock cylinder 1, dial 2, locking bar 3, code-disc 6, turning handle 7 all adopt general disc type mechanical code lock general part, the thick copper coin of cam 4 usefulness 5MM is made through machining, and fixture block 5 is one section rod iron of Ф 6MM.The steel plate of metering chamber door is thick to be 2MM, the center to center distance of dial and lock cylinder is 56MM, the code-disc diameter is 60MM, the long 110MM of locking bar, stroke 15MM, the stroke 15MM of fixture block, the axial length overall 66MM of dial, the space that whole lock accounts for is 200 * 110 * 45MM, and working condition of the present utility model is described below.Unblank: key is inserted lock cylinder and rotation, so cam unclamps fixture block and dial, this moment, unlocking person need be by the presetting cipher rotating driver plate, stir when finishing, the breach of three code-discs aligns just, as Fig. 1 position, at this moment, pulling turning handle unblanks the locking bar translation; Locking: pull turning handle and make the locking bar front end enter lock-bit, code-disc is left in the rear end, rotates code-disc arbitrarily and makes breach dislocation, and the twisting key makes cam push away fixture block and upwards pushes down the dial axle and finish lock-bit.The code-disc structure of this lock is all identical with general disc type mechanical code lock with the method for changing mechanical cipher.
