Abstract

The utility model relates to a 24-hour clock comprising a dial plate, pointers, and a driving system. The driving system comprises a passing wheel piece, a second wheel axle, a passing wheel axle, a minute wheel piece, a minute wheel axle, a striding wheel piece, an hour wheel axle, and a striding wheel axle, wherein, the passing wheel piece is engaged with the second wheel axle, the passing wheel axle is engaged with the minute wheel piece, the minute wheel axle is engaged with the striding wheel piece, and the hour wheel axle is engaged with the striding wheel axle. The driving ratio of an hour wheel and a minute wheel is 1: 12, and the driving ratio of the minute wheel and a second wheel is 1: 120. When an hour pointer of the utility model turns a circle, the time is 24 hours. When a minute pointer turns a circle, the time is 2 hours. When a second pointer turns a circle, the time is 60 seconds. And the 24-hour clock is combined with a novel scale design of the dial plate, so that people can conveniently and accurately identify the time display, and the traditional reading mode can not confuse people when people read the time display.

Description

24 hours system clock and watch

The utility model relates to a kind of clock and watch, particularly a kind of 24 hours system clock and watch.

The patent No. is that 91205640.1 Chinese patent discloses a kind of 24 hours system clock and watch, it is 24 hours that these clock and watch hour hands circle, it still is 60 minutes that minute hand circles, it still was 60 seconds that second hand circles, obscure because people cause with 12 hours clock and watch reading methods of tradition when show reading time easily, make people than difficulty recognize time demonstration exactly.

The purpose of this utility model is: a kind of 24 hours system clock and watch are provided, people can not be caused with traditional reading method when show reading time obscure, make people's recognize time demonstration exactly.

The utility model is achieved in that a kind of 24 hours system clock and watch, comprises dial plate, pointer, kinematic train, and pointer places the dial plate front, and kinematic train places the dial plate back, and described pointer comprises hour hands, minute hand; The small time taking that described dial plate indicates is 24 hours; Described kinematic train comprises respectively setting pinion and the second wheel axle of engagement, mistake wheel shaft and minute wheel sheet, minute wheel pivot and back gear sheet, the time wheel shaft and minute wheel pivot; When described hour hands are connected on the wheel shaft; Described minute hand is connected on the minute wheel pivot; The ratio of gear of hour wheel and minute wheel is 1: 12; The ratio of gear of minute wheel and second wheel is 1: 120.

Described pointer also comprises second hand, and second hand is connected on the second wheel axle.

The minute track that described dial plate indicates is divided into left part and right part two parts along the vertical line direction, and every part indicated 60 minutes separately; The time of hour hands indication, the reading of minute hand indication was at left part when being odd number; The reading of time of hour hands indication when being even number, minute hand indication is at right part.

The utility model is owing to adopt brand-new ratio of gear, make clock and watch realize that it is 24 hours that hour hands circle, it is 2 hours that minute hand circles, it is 60 seconds that second hand circles, and in conjunction with novel dial scale design, make people use the utility model to come exactly easily recognize time shows that people can not cause with traditional reading method and obscure when show reading time.

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is a cassette mechanism structure synoptic diagram of the present utility model.

Fig. 2 is the dial plate synoptic diagram of a kind of embodiment of the utility model.

As shown in Figure 1, setting

pinion

2 and 1 engagement of second wheel axle and 2 coaxial are crossed

wheel shaft

3 and 4 engagements of minute wheel sheet, with 4 coaxial minute wheel pivots 5 and 6 engagements of back gear sheet, with 6 coaxial minute wheel pivots 7 with the time wheel shaft 8 engagements; When hour hands 11 are connected on the wheel shaft 8; Minute hand 10 is connected on the minute wheel pivot 5; Second hand 9 is connected on the second wheel axle 1.The ratio of gear of hour wheel and minute wheel is 1: 12; The ratio of gear of minute wheel and second wheel is 1: 120.When the utility model is wall clock, the number of teeth of second wheel axle 1 is 8 teeth, the number of teeth of setting pinion 2 is 60 teeth, the number of teeth of crossing wheel shaft 3 is 4 teeth, the number of teeth of minute wheel sheet 4 is 64 teeth, and the number of teeth of minute wheel pivot 5 is 16 teeth, and the number of teeth of back gear sheet 6 is 48 teeth, the number of teeth of minute wheel pivot 7 is 12 teeth, the time wheel shaft 8 the number of teeth be 48 teeth.When the utility model was wrist-watch, 1 was 7 teeth, and 2 is 56 teeth, and 3 is 3 teeth, and 4 is 48 teeth, and 5 is 8 teeth, and 6 is 20 teeth, and 7 is 10 teeth, and 8 is after 48 teeth, 1 and 2 mesh, to consider the error that the technology corner forms, and actual gear ratio is 1: 7.5.

As shown in Figure 2, the small time taking that dial plate indicates is 24 hours, and the minute track of sign is divided into left part and right part two parts along the vertical line direction, and every part indicated 60 minutes separately; The time of hour hands indication, the reading of minute hand indication was at left part when being odd number; The time of hour hands indication, the reading of minute hand indication was at right part when being even number, and the time of representing among the figure is 9: 29.
