TWM608292U - New clock with sub-week clock - Google Patents

Abstract

The primary clock and the secondary clock change the original independent secondary clock to be controlled by the master clock. The necessary voltage is supplied to the negative pole of the secondary clock via the Timer IC every 12 hours and minutes. The positive pole of the secondary clock is fixedly connected. The VCC of two 1.5V AA batteries is about 3 volts. The length of the low voltage of the negative pole of the subweek depends on the resistance of the attached Timer IC. The time for each revolution of the subweek (twice a day): 3,600 seconds÷14=257.14 seconds, about 4 minutes and 17.14 seconds

After many experiments, the IC resistance is set to 920KΩ.

The indication of the day of the week in the sub-week clock is divided into 12 boxes, the third box is the first point means 12 noon, and the 9th box is the second point means 12 o'clock in the evening.

The mother clock and the secondary clock only use electricity for about 8 minutes and 34.28 seconds a day, which saves electricity.

Because the connecting lines of the hour hand and the minute hand are connected in series, it is only effective when the two are connected at the same time. When the hand turns to 12 hours, it first touches its trapezoidal copper pillar, and the equal minute hand touches the copper pillar together. The sub-week clock starts to rotate. After 4 minutes and 17.14 seconds, the hour hand will stop at the first noon of that day or the first midnight. two points.

In addition, the material of the hour and minute hands of the mother clock is made of rubber, which is relatively tight, which helps the two lines to contact each other.

Description

Mother clock and child week clock

clock

The clock used to have seconds, minutes and time

In addition to the prior art, a small so-called sub-weekly clock is attached to the same time dial.

First install one and two AA 1.5 volt batteries in the master clock and the attached battery box. Turn the master clock to the current time. If the current time is before 12 noon, turn the sub-weekly clock to the first o'clock of the day, if it is after 12 noon, turn the sub-weekly clock to the second o'clock.

In an embodiment of the present invention, the above-mentioned modern mother clock and sub-circle clock further include the rubber-made hour hand (10) whose height must exceed the hour hand of the sub-circle clock.

In an embodiment of the present invention, the above-mentioned modern mother clocks and sub-period clocks further include the rubber-made minute hand travel (20), because the minute hand is longer than the hour hand and is easier to move, and it needs a longer travel time to reduce pressure. The installation steps are as follows ( 10) Same.

In an embodiment of the present invention, the above-mentioned modern mother clock and secondary clock further include Timer IC (30) and Timer IC trigger ‘t’ pull up resistor 10KΩ 1/4W resistor R2(31).

In an embodiment of the present invention, the above-mentioned modern mother clock and secondary clock further include Timer IC auxiliary resistor R1 (40).

In an embodiment of the present invention, the above-mentioned mother clock and the secondary clock, and the battery box (51) including the secondary clock plate, does not contain 1.5 volt AA batteries. It is an empty box, and its (52) is connected to the positive electrode of (51). (53) Connect the negative terminal of (51).

10: The movement of the rubber hour hand: its height must exceed the hour hand of the sub-week clock

11,21: Use AWG24 naked wires to disassemble into a ladder type, the width of the ladder is about 3mm, and its height is 2mm higher than the hour hand and minute counter.

20: The movement of the rubber-made minute hand, because the minute hand is longer than the hour hand and it is easier to move and requires a longer time to reduce pressure. The installation steps are the same as 10
