Abstract

The utility model discloses a clock. An hour hand runs one circle in one day. The transmission ratio of a time gear in a mechanical gearwheel and a time gear is 1: 8. A dial is provided with hour timing and minute timing tables of an inner circle and an outer circle. Thus, a visual definite timing clock is obtained.

Description

A kind of clock and watch

What the utility model related to is a kind of clock and watch.

At present, the clock and watch that provide on market great majority adopt the mechanical gear transmission, cross tooth with the time ratio of gear between the tooth be 1: 4, thereby tooth axle hour hands in a day turned round for two weeks when tooth rotates drive when making, and can not clearly show on the clock face.1 point, 2 points in the afternoon ... correspondingly add 12 until at 12 in evening, and reach the purpose that clocks that this method that clocks is in daily life more inconvenience, will not be directly perceived.

The utility model provides to make and can show one day 24 hours clock and watch on the clock face.

When the purpose of this utility model is achieved in that clock face, divide pointer by the mechanical gear transmission.At first, in mechanical gear cross tooth and the time ratio of gear between the tooth be 1: 8, with the time tooth axle in one day, drive hour hands and rotate a week, thereafter, positive north on corresponding clock face is starting point, the interior circle of making the average lattice of 24 lattice is the form that clocks, and it is identical that cylindrical has average lattice of 60 lattice and existing clock and watch to keep the score, thereby reach the purpose that clocks.

The utility model compared with prior art, its maximum characteristics are that hour hands were transported and circle in one day, can show in one day 24 hours clear and definite, need not addition, come into plain view when seeing the time, ocular and clear, reach a kind of effect that intuitively clocks.

For a more detailed description to the utility model in conjunction with the accompanying drawings by following embodiment.

Fig. 1 be cross in the mechanical gear tooth and the time tooth mesh schematic representation

Fig. 2 is the clock face synoptic diagram

Among Fig. 1, cross tooth 1 and the time tooth 2 engagements, its ratio of gear is 1: 8, among Fig. 2, clock face 3 is provided with inside and outside circle 4,5, interior circle 4 is the average lattice of 24 lattice, is the lattice that clock, cylindrical 5 has the average lattice of 60 lattice to be the lattice of keeping the score.

Claims (1)

1, a kind of clock and watch during clock face (3), divide pointer by the mechanical gear transmission, is characterized in that:

In mechanical gear cross tooth (1) with the time ratio of gear between tooth (2) be 1: 8, clock face (3) be provided with 24 lattice on average with inside and outside circle (4), (5) of the average lattice of 60 lattice.
