Embodiment Construction

[0019] The analog radio clock of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited to this specific embodiment.

[0020] like figure 1 As shown, the analog radio clock includes a front splint 1, a rear splint 3, and a middle splint 2. The stepping motor and the gear transmission system are installed in the cavity formed between the front splint 1 and the rear splint 3, and the gears are realized through the middle splint 2. positioning.

[0021] In this embodiment, two stepping motors are adopted to control the second hand and the minute hand through the second hand transmission gears 5, 6 and the minute hand transmission gears 9, 10 respectively, so as to correct the time. The rotors 41 and 111 of the stepping motor are hard magnetic materials, and the stepping gears 4 and 11 of the stepping motor are plastic gears. There are annular gr...

Abstract

This invention discloses a pointer type electric wave bell. It contains frontal clamp, hinder clamp, arrow, geared system, step gear and hard magnetic material step motor rotor of stepping motor, step gear and step motor rotor in question are divided body structure and come together. The pointer type electric wave bell is easy to produce, enable to raise production efficiency and nodal production precision, especially adapted to batch process.

Description

technical field [0001] The invention relates to an analog clock, in particular to an analog radio clock with automatic time correction function. Background technique [0002] Due to the error of the clock itself, the problem of fast and slow will appear due to the accumulation of errors after a period of time. The radio-controlled clock is a kind of automatic calibration clock. By receiving the time code signal sent by the observatory, the circuit controls the stepping motor and the mechanical transmission system to continuously and automatically correct the deviation of the clock's travel time, so that the travel time of the radio-controlled clock remains consistent with the astronomical time-telling station. [0003] The movement part of the existing analog radio clock is composed of a circuit board, a dial, a pointer, a gear transmission system and a stepping motor installed in the clock case, and the pointer, the gear transmission system and the stepping motor are instal...
