Embodiment 1

[0028] Such as figure 1 As shown, the device consists of the following components:

[0029] The signal conversion device 2 can adopt a known photoelectric conversion assembly, which consists of an infrared light-emitting diode, two infrared receiving transistors, and a photoelectric wheel installed between the light-emitting tube and the receiving tube. The photoelectric wheel is linked with the turntable through a mechanical connection. , as the turntable rotates, the circumferentially distributed gear holes on the photoelectric wheel modulate the light emitted by the light-emitting diodes into pulse waves, which are received by two triodes and output electrical pulse signals, thus changing the direction and position of the turntable rotation The information is converted into two sets of electric pulse signals, that is, the first electric pulse signal and the second electric pulse signal. Properly arrange the positions of the two infrared receiving transistors so that the or...

Embodiment 2

[0062] Such as figure 2 As shown, the device consists of the following components:

[0063] The signal conversion device 2 adopts a known electromechanical rotary encoder assembly, and the rotary wheel of the encoder is linked with the turntable through a mechanical connection and rotates with the turntable. The encoder component has two encoding signal output ends. When the wheel rotates clockwise, the first output end outputs the electrical pulse signal 11 first; when the wheel rotates clockwise, the second output end outputs the electrical pulse signal 12 first. . The number of pulses contained in the two sets of electrical pulse signals is proportional to the angle of rotation of the encoder wheel, and the frequency of the pulse signal is proportional to the rotation rate of the encoder wheel. The difference from Embodiment 1 of the present invention is that the power supply of the electromechanical rotary encoder assembly in this embodiment is not controlled by the mea...

Abstract

The present invention discloses one kind of cipher inputting and cipher distinguishing device for turntable type cipher lock with low cost, great amount of cipher keys and simple cipher input and setting. The cipher inputting and cipher distinguishing device for turntable type cipher lock converts the lock turning direction and angle into digital signal; the digital signal is traced, determined, calculated and displayed; and based on the determination result and calculation result, corresponding logic judgment and execution are performed to realize the functions of cipher input, cipher distinction and cipher setting.

Description

technical field [0001] The invention relates to a combination lock, more specifically, to a combination input and identification device for a turntable type combination lock. Background technique [0002] The unlatching and setting of the mechanical turntable type combination lock combination that has been adopted is realized by the mechanical linkage mechanism inside the combination lock. The mechanical linkage mechanism is composed of mechanical parts such as a dial, 3 or 4 steering wheels, lock pins and springs. The dial and the steering wheel are arranged axially, and the torque transmission between them is realized by the positioning block on the steering wheel. The installation position of the positioning block determines the dial, the steering wheel and the mechanical linkage between the steering wheel. When the direction of rotation of the dial, the number of turns and the reached scale position meet the conditions determined by the preset position of the positioni...
