Abstract

The invention discloses a simple printing clock. The simple printing clock comprises a travel time mechanism and a manual printing mechanism which are driven by a sync motor, and the rotating speed of the sync motor is 1r/min. A cam on the tail of the output shaft of the sync motor drives a minute print wheel to advance one grid per minute via a driving lever mechanism; when the minute print wheel advances from the 59-minite grid to the 00-minute grid, a minute/hour print wheel pallet drives an hour print wheel to advance one grid; when the hour print wheel, which advances one grid per 60 minutes, advances from the 23-hour grid to the 00-minute grid, the cam and a rocking lever mechanism on the hour print wheel drive a week print wheel to advance one grid; and after a manual printing mechanism is pressed for certain times, a gear lug bar can drive a round hole ribbon gear and a square hole ribbon gear to rotate one gear simultaneously, and the square hole ribbon gear can drive a ribbon axle to rotate once, so that a ribbon core is enabled to rotate. The printing clock is favorable for users to reduce the production cost and convenient for routine maintenance.

Description

A kind of simple printing clock

Technical field

The present invention relates to a kind of simple printing clock.

Background technology

Present printing clock all will stay time keeping by acting on file or other paper of control circuit, there is the defective of circuit complexity in it, also will be by the first-class precise part of typewriting through a pin striker bump ink ribbon, can on file or paper card, produce printing effect, not only be not easy to safeguard, and manufacturing cost and use cost is all higher relatively.

Summary of the invention

Purpose of the present invention will provide a kind of simple printing clock that can overcome above-mentioned weak point exactly, and it need not control circuit, also need not accurate printhead.

The so-called a kind of simple printing clock of the present invention, mechanism and manual printing mechanism when it contains to walk is characterized in that:

1) during described walk mechanism comprise coaxial setting minute character wheel, hour character wheel and week character wheel, power when three kinds of character wheels are provided away by the syncmotor of 1r/min, wherein

Minute character wheel drives the per minute lattice that advance by the cam of syncmotor output shaft afterbody through lever body, and has the unidirectional bar of minute character wheel to prevent a minute character wheel counter-rotating; And, promptly drive hour character wheel lattice that advance, and there is the unidirectional bar of hour character wheel to prevent a hour character wheel counter-rotating by a minute hour character wheel ratchet when minute character wheel when lattice entered 00 minute lattice by 59 minutes;

When hour character wheel when lattice entered 00 hour lattice by 23 hours, cam on hour character wheel and rocking lever mechanism will drive the week character wheel lattice that advance, and have the unidirectional bar of week character wheel to prevent week character wheel counter-rotating;

2) described manual printing mechanism comprises the hand pressing board, gear sour jujube bar, circular hole colour band gear, square hole colour band gear, colour band wheel shaft and limited block, when pressing the hand pressing board to position that limited block limits, corresponding minute character wheel, the font of hour character wheel and the lower edge of week character wheel will be imprinted on and stay time keeping on file or the paper card, simultaneously, the gear sour jujube bar that is fixed on the mainframe makes circular hole colour band gear rotate a tooth, when catching on two dark teeth of circular hole colour band outer gear rim, pushes by gear sour jujube bar printing again, then gear sour jujube bar can drive circular hole colour band gear and square hole colour band gear rotates a tooth simultaneously, and square hole colour band gear can drive the colour band wheel shaft and rotate once, and the colour band core is rotated.

In addition, described minute its outer rim of character wheel is equipped with the arabic glyphs of 00-59, and it rotates just in time when walking 60 a minutes week; Described hour its outer rim of character wheel is equipped with the arabic glyphs of two groups of 00-23, and it rotates a week, and just in time two round the clock when walking; Described week, its outer rim of character wheel was equipped with the font on six groups of Monday-Sundays, and it rotates six week when walking just in time in a week.

The invention has the beneficial effects as follows: simple structure, be convenient to safeguard that manufacturing cost and use cost is all relatively low.

Embodiment

As seen from Figure 1, place the syncmotor 2 of printing clock mainframe 1 one ends, 1r/min will be by the cam 3 of syncmotor output shaft afterbody, make lever body 4 per minutes stir minute character wheel 5 lattice that advance, the effect of the unidirectional bar 6 of minute character wheel is to prevent 5 counter-rotatings of minute character wheel; When per minute advances minute character wheel 5 of lattice lattice entered 00 minute lattice by 59 minutes, promptly drive hour character wheels 8 lattice that advance by minute hour character wheel ratchet 7, hour character wheel 8 also has the unidirectional bar of hour character wheel to prevent its counter-rotating; Hour character wheel 8 of the per 60 minutes lattice that advance drives week character wheels 10 lattice that advance by cam on hour character wheel and rocking lever mechanism 9 when lattice entered 00 hour lattice by 23 hours, and has the unidirectional bar 11 of week character wheel to prevent week character wheel 10 counter-rotatings;

The structure of the manual printing mechanism of the present invention has been shown among Fig. 2 and Fig. 3.When manually pressing hand pressing board 12, mainframe 1 can move around the shaft, limited block 17 is when then assurance is depressed into certain position, minute character wheel 5, hour character wheel 8, the font of the lower edge of week character wheel 10 will stay time keeping at file or the paper card put into from the hand hay cutter limit, the gear sour jujube bar 13 that is fixed on simultaneously on the mainframe 1 rotates a tooth with circular hole colour band gear 14, when wherein two the dark teeth that catch on circular hole colour band gear 14 when gear sour jujube bar 13 are pushed and are printed, said gear sour jujube bar 13 can drive circular hole colour band gear 14 and square hole colour band gear 15 rotates a tooth, and square hole colour band gear 15 drives colour band wheel shaft 16 and rotates once, and the colour band core is rotated.

Minute character wheel 5 its outer rims shown in Fig. 4 are equipped with from 00 successively to 59 arabic glyphs, and it rotates when walking 60 a minutes week; Hour character wheel 8 its outer rims shown in Fig. 5 are evenly equipped with two groups from 00 successively to 23 arabic glyphs, and it rotates a week, and just in time two round the clock when walking; Week character wheel 10 its outer rims shown in Fig. 6 are evenly equipped with six groups of fonts from the Monday to the Sunday, and it rotates six week when walking just in time in a week.

When powering on first, the present invention should manually configure the corresponding time (minute, hour and what day) by the user, put into need typescripts or paper card from side during use, press hand pressing board 12 to the position that limited block 17 limits, can on file or paper card, stay time keeping.

In that the time keeping print quality is required is not on the very high equipment, adopts the present invention to help the user to reduce production costs, and is convenient to product maintenance simultaneously yet.
