Description

Clock with world timing

The utility model relates to a kind of with the visual type device of instruction time, specifically belongs to a kind of device that can indicate world's different time zone time.

Increasing along with international association, trade, people more and more wish to grasp simultaneously the time situation of world's different time zone, for addressing this problem, some big hotels, airport, harbour, the normal employing is provided with several clock and watch at reception hall, and the time of each area of clock and watch indication or country, the problem that this method exists is that limitation is very big, people have left reception hall, just can not accurately understand the time situation of various regions and nations.CN1063764A provides a kind of can show the device of time all over the world simultaneously, this device comprises watchcase, movement, 12 o'clock tabulation dishes, 24 o'clock tabulation dishes, dials during annular, minute hand, second hand, its annular hour hands panel surface is divided into 24 time zones, hour hands are arranged in the middle of the time zone, dials needle shaft rotation at any time during annular, its drive connection is to adopt the number of teeth of adjusting 12 o'clock each wheels of system movement hand train wheel, the ratio of gear of former minute wheel and hour wheel changes 24:1 into by 12:1, be minute wheel revolution 24 circles, hour wheel turns around, people can grasp the time situation of various regions and nations simultaneously according to the indicated time of the hour hands on the different time zone.The existing weak point of this device is, can not utilize existing 12 o'clock system watch and clock movements, so manufacture process requirement height, and have only minute hand and second hand on 12 o'clock designed tabulation dishes, people can not know this area time at a glance, also have, when the annular hour hands of these clock and watch are the counter clockwise direction tropometer, do not meet the custom of people's meter reading.

The purpose of this utility model is to overcome weak point of the prior art, provide a kind of and increased the time that the time zone time set makes it accurately to indicate 24 time zones, the world and the country one belongs on the system clock and watch at former 12 o'clock, can indicate this area time again cheer and brightly, and easy to use, the simple a kind of new-type global Chronograph timepiece of manufacturing process.

The purpose of this utility model realizes by following design.

Dials, 12 o'clock tabulation dishes, 24 o'clock tabulation dishes when the designed global Chronograph timepiece of the utility model comprises table drain pan, movement, bar shaped hour hands, minute hand, second hand, annular, adopting the movement of 12 o'clock system clock and watch is power source, when the hour hand axle of movement and annular, between the dials variable transmission mechanism is set, hour hand axle by variable transmission mechanism with when annular dials realize variable motion, its ratio of gear is 2:1; On the dials global timing display device is set during annular, dials is in the same way with the speed rotation when this device and annular.People can carry out global timing by the indication on the global timing display device.

The designed variable transmission mechanism of the utility model is by driving wheel, transmission gear, dials constitutes when having internal tooth annular; Driving wheel is arranged on the hour hand axle, does in the same way with the speed rotation with hour hand axle, and driving wheel dials when having internal tooth annular is realized the speed change transmission by transmission gear.The preferably even number combination of set transmission gear, dials is done rotation in the same way with hour hand axle when guaranteeing annular, to meet the custom of people's meter reading, during fabrication also can be according to the size of clock and watch, the space in the clock and watch, the transmission of selection duplicate gear.

The utility model when annular on the dials set global timing display device be to constitute by supporting mass, time zone mark writing paper, time zone hour hands; Wherein supporting mass comprises ring and outer shroud in one, is linked into an integrated entity by gusset between interior ring and the outer shroud, can to guarantee the standard of overall dimensions, be easy to standardization and exchange by the mould single injection-molded during this component processing; Dials compresses the realization wringing fit when outer shroud of supporting mass and annular.Surperficial uniform 24 time zones mark writing paper of supporting mass, the outer rim middle part of time zone mark writing paper is provided with the time zone hour hands, is used to indicate the time in each time zone.

For satisfying the different requirements of people to the national title of time zone, place demonstration, can connect the shrinkage pool that replaceable time zone mark writing paper is set on the gusset, place the time zone in the shrinkage pool and mark writing paper, a spacing holder card is set under the shrinkage pool, take off spacing holder card, promptly replaceable time zone mark writing paper.

Be described in further detail the utility model below in conjunction with drawings and Examples.
