Abstract

The invention provides a miniature counter, which comprises a housing, a digital wheel, a gear set, a stepper motor and a circuit board, wherein a digital wheel arranging hole is arranged at the front face of the housing; the digital wheel is the digital wheel of a conventional mechanical counter and is arranged on the back face of a front panel of the housing, the front end face of the digital wheel is positioned in the digital wheel arranging hole on the housing, connected with an output shaft of the gear set and used for recording data and displaying the counting result; the gear set is the gear set for the conventional counter and is arranged in the housing, an input shaft of the gear set is connected with a main shaft of the stepper motor, and the output shaft of the gear set is connected with the digital wheel; the stepper motor is arranged in the housing, the main shaft of the stepper motor is connected with the digital wheel through the gear set; and the circuit board is the circuit part of the counter. On the premise of accurately recording the number of the pulse signals, the miniature counter provided by the invention can achieve low energy consumption, low self-heating effect and good anti-shocking performance.

Description

Technical field [0001] The invention belongs to the technical field of pulse counting instruments, and particularly relates to a micro counter. Background technique [0002] At present, the known counter drive parts that are powered by a two-wire pulse signal and displayed by a digital wheel are all electromagnets. When the measured pulse signal is turned on, current flows through the solenoid coil to generate a magnetic field. The solenoid pulls in and drives the pawl, and the pawl strokes a tooth on the ratchet. At this time, the metal spring is also pulled and is in a state of energy storage. . When the pulse signal disappears, the electromagnet coil is de-energized, the magnetic field disappears, the electromagnet releases the metal spring to reset, drives the pawl, and the pawl pushes the ratchet wheel to rotate one tooth, and the digital wheel records the next number. When N pulse signals are turned on, the above process is repeated, and the digital wheel records N number...
