Abstract

The utility model discloses a novel clear device of a coded lock, wherein the clear device is arranged in a lock body, is connected with one end of a central shaft in the lock body, and comprises a clear knob and a gear connected with one end of the central shaft, the clear knob is of a circular shape, internal teeth are uniformly distributed on the inside wall of the clear knob along the peripheral direction, and the clear knob is meshed onto the gear through the internal teeth; and the clear knob is clamped and fixed in the lock body and can rotate around the circle center thereof, part of the clear device is penetrated through one side of the lock body to be exposed outside the lock body, a correction mark is arranged on the clear knob, an indication mark corresponding to the correction mark is arranged at the side of the clear knob outside the lock body, and the correction mark is aligned to the indication mark when the clear knob rotates to a certain degree. The structure is simple, and the operation is convenient.

Description

Novel cipher lock zero clearing device

Technical field

The utility model relates to a kind of zero clearing device, particularly a kind of novel cipher lock zero clearing device.

Background technology

Coded lock is widely used in various fields, need be provided with the function of zero clearing device to realize that the replacement password is imported on some specific coded lock, zero clearing apparatus structure complexity commonly used, and troublesome poeration brings inconvenience to the user.

Summary of the invention

In order to overcome above-mentioned defective, the utility model provides a kind of novel cipher lock zero clearing device, and this zero clearing apparatus structure is simple, easy to operate.

The utility model for the technical scheme that solves its technical problem and adopt is: a kind of novel cipher lock zero clearing device, described zero clearing device is located in the lock body, and be connected in an end of central axis in the lock body, described zero clearing device comprises a zero clearing knob and is connected in the gear of central axis one end, described zero clearing knob is circular, and the inside wall of zero clearing knob is provided with the internal tooth around circle distribution, and described zero clearing knob is engaged on the gear by internal tooth; The zero clearing knob is fastened in the lock body and can rotates around himself center of circle, and the zero clearing knob portion wore lock body one side and was placed on outside the lock body, described zero clearing knob is provided with a collimating marks, the lock body outside is positioned at zero clearing knob side and is provided with a cue mark corresponding with collimating marks, and collimating marks is alignd with cue mark when the zero clearing knob rotates to a certain degree.

The beneficial effects of the utility model are: this zero clearing device adopts inside and outside gears engaged, central axis is revolved the flat circle action that the action of turning around changes the zero clearing knob into, rotate the zero clearing knob after the collimating marks on the alignment of the cue mark on the zero clearing knob lock body, can realize the zero clearing action of coded lock, this is simple in structure, and easy to operate.

The specific embodiment

Embodiment: a kind of novel cipher lock zero clearing device, described zero clearing device is located in the lock body 1, and be connected in an end of central axis 4 in the lock body 1, described zero clearing device comprises a zero clearing knob 2 and is connected in the gear 3 of central axis 4 one ends, described zero clearing knob 2 is circular, and the inside wall of zero clearing knob 2 is provided with the internal tooth 21 around circle distribution, and described zero clearing knob 2 is engaged on the gear by internal tooth 21; Zero clearing knob 2 is fastened in the lock body 1 and can rotates around himself center of circle, and zero clearing knob 2 parts wore lock body 1 one sides and were placed on outside the lock body 1, described zero clearing knob 2 is provided with a collimating marks 5, lock body 1 outside is positioned at zero clearing knob 2 sides and is provided with a cue mark 6 corresponding with collimating marks 5, and collimating marks 5 is alignd with cue mark 6 when zero clearing knob 2 rotates to a certain degree.

The operating principle that the utility model is applied in the tactile coded lock is: when rotating zero clearing knob 2, internal tooth 21 driven gears 3 rotate, thereby driving central axis 4 rotates, bullet pad in the lock body 1 password wheels rotates under the drive of central axis 4 simultaneously, when turning to certain angle, pushing against after sheet pushes against shoulder with interior cipher wheel on the bullet pad, and then cipher wheel and the rotation of outer cipher wheel in driving, because the bullet pad on each password wheels all is that spline is in central axis 4 usually, so rotary middle spindle 4 greater than the angle of a circle after and when making collimating marks 5 aim at cue marks 6 (during the initial setting password, make the calibration arrow promptly aim at arrow), all password wheels promptly are returned to the angle when just the beginning and end are by the sense of touch button, finish the zero clearing action this moment.

Claims
