[0024] A watch movement structure of a jumping hour watch, such as Figures 1 to 4 As shown, it includes a bottom plate 13, a time wheel 11 driven by a mainspring is coaxially arranged at the center of the bottom plate 13, a mounting plate 8 is arranged on the bottom plate 13, a first transmission mechanism 5 meshing with the time wheel 11 and used to drive the minute wheel 4 to rotate 180 degrees and reset is arranged on the mounting plate 8, a second transmission mechanism 7 meshing with the time wheel 11 and used to drive the time disk 1 to rotate is also arranged on the mounting plate 8, the time disk 1 is rotatably arranged on the mounting plate 8, and a splint 3 for axially positioning the first transmission mechanism 5 and the second transmission mechanism 7 is arranged on the mounting plate 8 and located on the inner side of the time disk 1.

[0025] The hour wheel 11 is arranged at the center of the watch. The patent does not have a second hand. Instead, an hour disk 1 is used to replace the existing hour hand. The hour disk 1 is arranged on the periphery of the splint 3. Numbers 1 to 12 on the hour disk 1 represent different full hours respectively. An observation window (not shown in the figure) is provided on the watch. Which number on the hour disk 1 jumps to the observation window represents the time. The numbers on the hour disk 1 are not shown in the figure.

[0026] The minute wheel 4 is used to drive the minute hand to rotate. The minute wheel 4 and the minute hand are set at the six o'clock position of the watch. After the minute hand rotates 180 degrees, it means that one hour has passed. Then the minute wheel 4 and the minute hand are reset. The structure is novel and ingenious.

[0027] The outer ring of the hour disc 1 fits with the inner wall of the mounting disc 8, and the inner ring of the hour disc 1 fits with the outer ring of the splint 3. In this way, the hour disc 1 can be driven to rotate without deviation.

[0028] As described above for the core structure of the jumping-hour watch, the first transmission mechanism 5 includes a first gear set 501 meshing with the hour wheel 11, a second gear set 502 meshing with the first gear set 501, and a third gear 503 meshing with the second gear set 502. An escapement wheel 504 that rotates synchronously with the third gear 503 is provided on the third gear 503. A balance wheel 505 that is driven to rotate by the escapement wheel 504 and further drives the minute wheel 4 is hinged to the mounting plate 8.

[0029] As Figure 3 shown, the first gear set 501 includes a large gear and a small gear arranged coaxially, with the large gear on top and the small gear below; the second gear set 502 also includes a large gear and a small gear arranged coaxially, with the large gear below and the small gear on top; the third gear 503 is a large gear, and an escapement wheel 504 is coaxially provided on the third gear 503, and the escapement wheel 504 rotates together with the third gear 503.

[0030] The large gear of the first gear set 501 meshes with the hour wheel 11, the small gear of the second gear set 502 meshes with the large gear of the second gear set 502, the small gear of the second gear set 502 meshes with the third gear 503. A plurality of teeth are provided on the outer edge surface of the escapement wheel 504, and a pawl portion 5051 that engages with the teeth on the escapement wheel 504 is further provided on the balance wheel 505. The pawl portion 5051 and the balance wheel 505 are an integral part, and a sector gear that meshes with the minute wheel 4 is provided on the balance wheel 505.

[0031] After the escapement wheel 504 rotates one full circle, the balance wheel 505 is driven to rotate half a circle. The escapement wheel 504 is in the shape of a comma, so that the pawl portion 5051 of the balance wheel 505 will quickly jump back to the starting position after rotating one full circle on the escapement wheel 504. In this way, after the minute wheel 4 rotates 180 degrees, the balance wheel 505 drives the minute wheel 4 to quickly reset.

[0032] An arc-shaped plate 14 is provided on the mounting plate 8. Both ends of the arc-shaped plate 14 are fixed to the mounting plate 8 by screws, and the minute wheel 4 is installed on the lower surface of the arc-shaped plate 14.

[0033] The clamping plate 3 is fixed to the mounting plate 8 by screws, so that the first transmission mechanism 5 and the second transmission mechanism 7 can be axially positioned on the mounting plate 8. Positioning holes for axially positioning the first transmission mechanism 5 and the second transmission mechanism 7 are provided on both the clamping plate 3 and the mounting plate 8. A first elastic piece 12 is provided on the mounting plate 8. The first elastic piece 12 is installed on the mounting plate 8 by screws, and the mounting plate 8 is installed on the watch bottom plate 13 by screws.

[0034] The first elastic piece 12 is approximately U-shaped, one end of the first elastic piece 12 abuts against one side of the balance wheel 505, and the other end abuts against the groove of the mounting plate 8. The first elastic piece 12 and the pawl portion 5051 are located on opposite sides of the balance wheel 505, and the pawl portion 5051 is integrally arranged on the balance wheel 505. The function of the first elastic piece 12 is to prevent the cannon pinion 4 from rotating at an angle exceeding 180 degrees.

[0035] As described above, the movement structure of the jumping hour watch, the second transmission mechanism 7 includes a fourth gear set 701 meshing with the hour wheel 11, a fifth gear set 702 meshing with the fourth gear set 701, and a sixth gear 703 meshing with the fifth gear set 702, and the sixth gear 703 is provided with a paddle 9 driven by the sixth gear 703 to drive the hour disk 1 to rotate.

[0036] like Figure 3 As shown, the fourth gear set 701 and the first gear set 501 are respectively arranged on two opposite sides of the hour wheel 11, and the fourth gear set 701 includes a large gear and a small gear arranged coaxially, with the large gear on the top and the small gear on the bottom; the fifth gear set 702 also includes a large gear and a small gear arranged coaxially, with the large gear on the bottom and the small gear on the top; the sixth gear 703 is a large gear.

[0037] The large gear of the fourth gear set 701 is meshed with the hour wheel 11, the small gear of the fourth gear set 701 is meshed with the large gear of the fifth gear set 702, the small gear of the fifth gear set 702 is meshed with the sixth gear 703, and a plurality of inner protrusions 101 cooperating with the paddle 9 are symmetrically arranged on the inner side of the hour disk 1. The paddle 9 is coaxially arranged with the sixth gear 703, and the paddle 9 is driven to rotate by the sixth gear 703. The paddle 9 on the sixth gear 703 is used to drive the hour disk 1 to rotate, and the paddle 9 drives the hour disk 1 to rotate counterclockwise through the inner protrusions 101.

[0038] The mounting plate 8 is also provided with a baffle 6 for limiting the position of the hour disc 1 and a second elastic piece 10 against the baffle 6. An inner groove is formed between two adjacent inner protrusions 101. One end of the baffle 6 is hinged on the hour disc 1 and the other end cooperates with the inner groove. A convex plate portion 801 is provided on the mounting plate 8. The second elastic piece 10 is also approximately U-shaped, with one end against the rear side of the baffle 6 and the other end against the convex plate portion 801. The convex plate portion 801 is an integral part with the mounting plate 8. The baffle 6 and the second elastic piece 10 are combined to prevent the hour disc 1 from jumping too much or too little every hour.

[0039] There is an observation window on the watch. There are twelve hourly moments engraved on the hour plate 1, so there are twelve corresponding inner grooves. The baffle 6 is hinged on the mounting plate 8 by screws. The part of the baffle 6 that matches one of the inner grooves is approximately triangular. The triangle has an inclined plane A and an inclined plane B. The slope of the inclined plane A is larger, and the slope of the inclined plane B is smaller. The inclined plane B is on the left side of the inclined plane A. Figure 3 As shown, the hour disk 1 does not rotate once every hour. The hour disk 1 is driven to rotate by the paddle 9. The inner protruding piece 101 on the hour disk 1 will quickly slide down from the inclined surface B after turning over the inclined surface A counterclockwise. Before the inner protruding piece 101 turns over the inclined surface A, the next hourly number on the hour disk 1 cannot be seen from the observation window. After the inner protruding piece 101 turns over the inclined surface A, the next hourly number on the hour disk 1 will quickly jump to the observation window.

[0040] In addition, after the lower step portion 102 is provided on the inner side of the hour disc 1, the inner protruding piece 101 is integrally provided inwardly, and the upper step portion 301 for limiting the hour disc 1 is integrally provided on the clamping plate 3. The upper step portion 301 is attached to the upper surfaces of the lower step portion 102 and the inner protruding piece 101, and the lower side surface of the upper step portion 301 is attached to the side surface of the inner protruding piece 101. In this way, when the hour disc 1 rotates, it will neither shake up and down nor shake left and right.

[0041] The embodiments described in the present invention are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by engineers and technicians in this field shall fall within the protection scope of the present invention.
