Abstract

The utility model discloses a transmission mechanism of a protector for a fingerprint seal. The transmission mechanism comprises a turning mechanism which is formed in the way that a master gear is arranged on a motor, is simultaneously fixed on a support and is pressed by a motor cover, a driven gear is meshed with the master gear and is connected with a worm, the other end of the worm is meshed with a worm wheel, the worm wheel is sheathed at one end of a rotating shaft, a rotating rack and the rotating shaft are connected with each other to form a whole, the seal is fixed on the rotating rack, the seal and the rotating rack can do 180 DEG rotation, and the turning mechanism is arranged in an outer shell. The transmission has the beneficial effects that the seal is in a sealed structure, and when a person wants to used the seal, a recorded fingerprint of another person is required for identification.

Description

Finger print stamp protector transmission mechanism

Technical field

The utility model relates to a kind of seal protective device, particularly a kind of seal protector transmission mechanism of opening realized by fingerprint.

Background technology

Traditional seal does not generally have any safeguard measure, under the unwitting situation of the owner, is used in the file of some illegal or infringement company's interest, enterprise or machine-operated department is caused great loss, especially legal person's chapter, the finance seal of enterprise.

The utility model content

At the deficiencies in the prior art, the utility model provides a kind of finger print stamp protector transmission mechanism that adopts fingerprint as input terminal.

To achieve these goals, technical solution adopted in the utility model is:

Finger print stamp protector transmission mechanism comprises switching mechanism, and described switching mechanism is: master gear is installed on the motor, be fixed on the support and simultaneously and push down by motor cover, from gear and master gear engagement, link to each other the other end of worm screw and turbine engagement with worm screw from gear; Turbine is enclosed within an end of rotating shaft, and swivel mount and rotating shaft are connected as a single entity, and seal is fixed on the swivel mount, and seal and swivel mount are with 180 ° of upsets, and switching mechanism places in the shell.

The other end of the relative turbine of rotating shaft is provided with crashproof that is used for controlling position of rotation.

The beneficial effects of the utility model: seal is in the structure of a sealing, when the people uses, must adopt the people's of typing fingerprint to discern.At first pass through power initiation, finger is placed on the fingerprint capturer of finger print stamp, after collecting user's fingerprint, at first the fingerprint image of gathering is carried out preliminary treatment, obtain the characteristic point of this fingerprint, and and fingerprint module in fingerprint module in the characteristic point of FLASH storage compare, if reaching certain value, the characteristic point coincidence rate just compares successfully, fingerprint module can be given signal of CPU after comparing successfully, CPU then can drive the upset of controlling organization driven gear, the user make seal be turned to the back side, so that can use.

The specific embodiment

The finger print stamp protector comprises control circuit, and control circuit is made of following element: the input of CPU (model ATMEGA16) control fingerprint and the processing of data and to the mechanical transmission component control instruction; Power supply is powered or is charged the entire circuit plate, is generally 4.2v lithium battery the best.Press key input device is by relevant management such as the registration of press key input device control fingerprint and deletions; Drive circuit drives the switching mechanism of seal, makes seal realize upset, and the CPU output order is controlled motor by drive circuit, and the upset finger print stamp is realized the finger print stamp operation of affixing one's seal; Fingerprint module by fingerprint module registration user's fingerprint, can carry out the management of rights of using management and fingerprint to the user, and fingerprint module also is connected with FLASH and cmos sensor.Power supply, press key input device, drive circuit, fingerprint module all are connected with CPU.USB interface can also be set, and USB interface is connected with CPU.Built-in charging circuit of USB interface and lithium battery, USB interface charging or is connected with computer is charged or communication.Also comprise clock chip, clock chip links to each other with CPU, realizes that clock is synchronous.Also comprise sound MIC, sound MIC links to each other with CPU, has the operation voice prompt function.Also comprise EPROM, EPROM links to each other with CPU, is used for preserving user's operating time and number of operations.Also comprise indicator lamp, indicator lamp links to each other with CPU, the display operation prompting, and under the general situation, it is proper operation that green light can be set, and red light is an operation failure, and the color of lamp can be provided with as required.

Structure chart shown in the drawing is the structure chart of a kind of embodiment, not only this structure of this patent protection, and adopting above-mentioned principle all is within the protection domain of this patent.

Ask for an interview Fig. 2-Fig. 6, shell 1 is the housing of a sealing, be provided with circuit part and mechanical driving part in the shell 1, in the present embodiment, circuit part is arranged on the upper end, the lower end is a mechanical driving part, the top of circuit part is provided with fingerprint module 6, fingerprint module 6 and login button 14, deletion button 19 all is arranged on the module rack 2, when needing to use, fingerprint module 6 identifications compare by the fingerprint of fingerprint capturer collection and the fingerprint of input, after collecting user's fingerprint, at first the fingerprint image of gathering is carried out preliminary treatment, obtain the characteristic point of this fingerprint, and and fingerprint module in the characteristic point of flash storage compare, just compare successfully if the characteristic point coincidence rate reaches certain value.Compare successfully the back fingerprint module and can give signal of CPU, other electronic component such as CPU all is arranged on the PCB circuit board 4.Lower part of frame is divided into mechanical driving part, and battery 5 is given wiring board and motor 22 power supplies, and motor cover 15 is arranged outside the motor 22, CPU sends instruction to motor 22, motor 22 rotates and drives master gears 20, again by worm screw 17 from gear 18 transmission worm screws 17, the other end of worm screw 17 passes to turbine 16.The rotation of turbine drives the rotation of rotating shaft 10 like this, and rotating shaft 10 and swivel mount 9 are one, and swivel mount lid 13 is arranged outside the swivel mount 9.Simultaneously, seal is embedded in the swivel mount 9, makes 180 ° of seal upsets like this, makes the chapter face be in operable state.For the control position of rotation of changing, on rotating shaft 10, installed one crashproof 7 additional.The two ends of whole rotating shaft 10 all are arranged on the cavity both sides that support 3 lower ends form.In addition, the bottom of protector is provided with an over cap 11.What be connected with circuit board in addition, counts button 8 and side press-key 12 in addition.
