[0002] In the past, the primary function of mechanical watches was to tell time. In the movement structure of these mechanical watches, the time indication was primarily a three-hand or two-hand time indication method, with either coaxial or non-coaxial indication. The typical structural characteristics of time indication were that the minute hand was fixed to the minute wheel, and the hour hand was fixed to the hour wheel, with the hour and minute hands rotating in a coaxial or non-coaxial circular trajectory. With the development of society and the economy, the function of watches is no longer just to tell time. More and more watch enthusiasts use watches as decorations or as collections. These watches have a variety of indication methods, making them look more novel and increasing their aesthetic value and artistic value. Summary of the Invention

DETAILED DESCRIPTION

[0039] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0040] Example 1

[0041] like Figures 1 to 4 As shown, a watch indicating mechanism comprises a fixed plate 1, an earth-moon indicating mechanism 2, an hour indicating mechanism 3, a minute indicating mechanism 4, and a gear transmission mechanism 5 connected to the fixed plate 1. The earth-moon indicating mechanism 2 includes a rotatable 24-hour globe 21 and a moon indicator 22 that orbits around the 24-hour globe 21. The hour indicating mechanism 3 is a chain indicating mechanism; the minute indicating mechanism 4 is a pointer-type minute indicating mechanism. The gear transmission mechanism 5 connects to the movement and transmits power to the earth-moon indicating mechanism 2, the hour indicating mechanism 3, and the minute indicating mechanism 4, respectively. The hour indicating mechanism 3 and the minute indicating mechanism 4 are located at different positions on the dial. The hour indicating mechanism uses a chain transmission, while the minute indicating mechanism uses a cam mechanism to transmit the indication. The earth-moon indicating mechanism surrounds the hour indicating mechanism and the entire dial, which does not affect the readability while being aesthetically pleasing, elegant, and stylish.

[0042] Specifically, the Earth-Moon indicating mechanism 2 also includes a lunar gear ring 23 and a gear ring support assembly 24. The lower end of the gear ring support assembly 24 is connected to the fixed plate 1, and the upper end of the gear ring support assembly 24 is provided with a guide wheel assembly 241. The gear transmission mechanism 5 transmits power to the guide wheel assembly 241. The guide wheel assembly 241 is engaged with the inner ring of the lunar gear ring 23. The lunar gear ring 23 rotates under the action of the guide wheel assembly 241. The lunar indicator 22 is fixedly connected to the lunar gear ring 23 and moves with the lunar gear ring 23 to simulate the revolution of the moon around the earth.

[0043] Specifically, the gear ring support assembly 24 includes a connecting post 242 and a supporting leg 243. Both connecting post 242 and supporting leg 243 are connected to the fixed plate 1. The connecting post 242 is connected to the gear transmission mechanism 5. The supporting leg has an inverted "V" structure and is fixed to the fixed plate 1 by screws. The connecting post 242 passes through the supporting leg 243 and is connected to the fixed plate 1. A bearing is provided between the connecting post and the fixed plate 1. The two feet of the supporting leg 243 form a triangle with the connecting post, which provides more stable support. The guide wheel assembly is connected to the upper end of the supporting post 242, and a bearing is provided between the supporting post 242.

[0044] Specifically, there are at least three groups of gear ring support assemblies 24, one of which is a connecting column 242 connected to the gear transmission mechanism 5. This group of support assemblies 24 acts as an active component to drive the lunar gear ring 23 to move, and the other two groups are driven components.

[0045] Specifically, if Figure 5 The hour indication mechanism 3 includes a chain 31, scale numbers 32, a first sprocket 33, a second sprocket 34, a sprocket shaft 35, and a scale indicator disk 36; the scale numbers 32 of 1-12 are fixedly connected to the chain 31; the first sprocket 33 drives the chain 31 to move, the second sprocket 4 is a driven sprocket, and the first sprocket 33 and the second sprocket 34 are both engaged with the chain 31; the sprocket shaft 35 is connected to the gear transmission mechanism 5 to obtain the motive force, the sprocket shaft 35 engages with the first sprocket 33, drives the first sprocket 33 to move, thereby driving the chain 1 to move, the scale numbers 32 are fixed on the chain 1 and move synchronously with the chain 1, and the scale indicator disk 36 is fixedly connected to the fixed disk 1, on which time indication symbols are provided, and the scale numbers corresponding to the indication symbols on the scale indicator disk are the current hours.

[0046] Specifically, a sprocket cover 38 is fixedly connected to the top of the first sprocket 33 and the second sprocket 34 by screws.

[0047] Specifically, a sprocket base 37 is placed on the fixed disk 1, and the second sprocket 34 is connected to the sprocket base 37. A spring 39 is provided between the sprocket base 37 and the fixed disk 1. One end of the spring 39 abuts the sprocket base 37, and the other end abuts the fixed disk 1. When the chain is affected by temperature changes and produces thermal expansion and contraction, the chain will be too tight or too loose and fall off. At this time, the spring 39 is deformed, causing the sprocket base to move, thereby adjusting the position of the sprocket base 37 and the tension of the chain to ensure accurate timing.

[0048] Specifically, the scale indicator disk 36 is a circular structure, fixed to the fixed disk 1 via a connecting column 361. The scale indicator disk 36 surrounds the 24-hour globe 21. The scale indicator disk 36 is provided with four numbers: 6, 12, 18, and 24. The 24-hour globe is provided with an indicator arrow corresponding to each number. The indicator arrow on the 24-hour globe is located between two adjacent numbers, indicating the time range of the day, indicating night or day.

[0049] Specifically, if Figure 6 As shown, the minute indicating mechanism 4 includes a minute hand dial 41, a minute hand 42, a camshaft 43, a spring 44, a cam rod 45, a minute hand cross wheel 46, a pressure plate 47, and a minute dial support column 48; the minute hand dial 41 is fixedly connected to the fixed plate 1 via the minute dial support column 48, and the minute hand dial 41 has a fan-shaped structure; the minute hand 42 is connected to the minute hand cross wheel 46 and rotates around the center of the minute hand cross wheel; the camshaft 43 is connected to the pressure plate 47, and the camshaft 43 moves under the action of the gear transmission mechanism 5. The camshaft 43 drives the cam rod 45 to swing. One end of the cam rod 45 is fixedly connected to the fixed plate 1, and the other end is provided with a waist-shaped hole and teeth. The fixed plate is also provided with a minute disk support column. The minute disk support column passes through the waist-shaped hole design to limit the swing angle of the cam rod 45. The teeth of the cam rod 45 are engaged with the minute hand jump wheel 46; the minute hand jump wheel 46 drives the minute hand 42 to move; one end of the spring piece 44 is connected to the minute hand dial 41. After the minute hand 42 moves from 0 to 60, it returns to 0 under the action of the spring piece 44.

[0050] Specifically, if Figure 7 As shown, the gear transmission mechanism 5 includes an hour wheel 51 and a minute wheel 52 connected to the movement;

[0051] The hour wheel 51 engages with the first minute wheel 53, driving the first minute wheel 53 to move. The first minute wheel 53 engages with the second minute wheel 55 and the first combination wheel 57, respectively, driving the second minute wheel 55 and the first combination wheel 57 to move. The first combination wheel 57 and the third minute wheel 551 are coaxially arranged, and the third minute wheel 551 moves synchronously under the action of the first combination wheel 57. The third minute wheel 551 engages with the sprocket shaft 35, driving the sprocket shaft 35 to move. The second minute wheel 55 is coaxially provided with a 24-hour hour wheel 552, which moves synchronously therewith. The 24-hour hour wheel 552 engages with the fourth minute wheel 59, which engages with the ring gear 591. The ring gear 591 drives the coaxial guide wheel assembly to move, thereby driving the moon ring gear 23 to move. The moon indicator 22 moves synchronously with the moon ring gear.

[0052] The minute wheel 52 engages the sixth minute wheel 56 via the fifth minute wheel 54 , and the sixth minute wheel 56 drives the cam shaft 43 on the minute indication mechanism 4 to move.

[0053] The working process of the present invention is as follows:

[0054] After the hour wheel 51 and minute wheel 52 receive power from the movement, the hour wheel 51 transmits power to the 24-hour globe 21 through the first minute wheel 53, the second minute wheel 55, and the 24-hour hour wheel 552, driving the 24-hour globe 21 to rotate, simulating the rotation of the earth.

[0055] The hour wheel 5151 transmits power to the chain 31 via the first intermediate wheel 53, the first combination wheel 57, the third intermediate wheel 551, the sprocket shaft 35, and the first sprocket 33. The scale numerals 32 on the chain 31 and the scale indicator disk 32 cooperate to indicate the time.

[0056] The minute wheel 52 drives the cam shaft 43 to move through the fifth minute wheel and the sixth minute wheel 56, and the cam rod 45 drives the minute hand 42 to rotate, thereby displaying the time.
