Description

Technical Field

[0001] This utility model relates to the field of medal technology, specifically to a rotating medal. Background Technology

[0002] Medals are awarded to winners of various competitions as proof of achievement. They are generally made of metal, and sports competitions typically award gold, silver, and bronze medals. Existing medals are mostly either one-piece or layered. One-piece medals are made from a single material, such as pure bronze medals. Layered medals are made by combining and inlaying multiple materials in different layers, such as gold-inlaid jade medals. However, neither of these types of medals features an internal design. Therefore, we need to develop a rotating medal that incorporates an internal design to enhance its playability. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the above-mentioned technology and provide a rotating medal.

[0004] A rotating medal includes a cover and a base plate at the bottom of the cover. The top surface of the cover has a large circular hole at its center. A support plate connected to the cover is located at the large circular hole. Between the support plate and the base plate at the center of the large circular hole, there are several fan-shaped blades that can be unfolded into a circle and folded together into a fan shape.

[0005] Several fan-shaped blades are equipped with a control device for controlling their unfolding and folding. The control device includes mounting pins, bearings, blade actuating components, and operating knobs.

[0006] The mounting nail includes a round rod and a nail head. A groove matching the nail head is provided at the center of the inner side of the base plate. The nail head is embedded in the groove and cannot rotate.

[0007] Each fan-shaped blade includes a circular plate and a fan blade. The circular plate has a small circular hole, an arc-shaped hole, and a hemispherical protrusion. The small circular hole is located at the center of the circular plate, and the center of the circle containing the arc-shaped hole is the center of the circular plate. The hemispherical protrusion is located on the circle containing the arc-shaped hole. Several fan-shaped blades are sequentially fitted onto the circular rod through the small circular holes. The height of the hemispherical protrusion is not greater than the thickness of the fan-shaped blade. The positions of the arc-shaped hole and the hemispherical protrusion on each fan-shaped blade are set according to the placement layer.

[0008] The base plate also has a hemispherical protrusion that matches the arc-shaped hole on one side of the groove;

[0009] The bearing is installed at the center of the large circular hole on the support plate;

[0010] The blade actuating component includes a circular piece with a cylinder at its center and a cylindrical tube at its bottom end. The cylindrical tube is rotatably fitted onto one end of the rod of the mounting nail. The blade actuating component has a through hole that matches the hemispherical protrusion. The through hole can be fitted onto the hemispherical protrusion of the topmost fan-shaped blade. The top end of the cylinder passes through a bearing and is fixedly connected to the operating knob, which is located on the outside of the support plate.

[0011] The base plate and the cover are bonded together with strong adhesive.

[0012] The bottom plate is equipped with a sling bolt on the side away from the cover.

[0013] Advantages of this utility model: This utility model has a reasonable structure and an internal rotating and folding design, which increases the internal structure of the medal. Through the internal unfolding and folding design, more display surfaces are provided. At the same time, the unfolding and folding are controlled by an external operating knob, which improves the versatility of the medal. It is flexible in wearing and displaying, and is practical and beautiful. Attached Figure Description

[0040] Example

[0041] like Figure 10 As shown, there are 11 fan-shaped blades 5, labeled a, b, c, d, e, f, g, h, i, j, and k. The groove 201 of the base plate 2 is quadrilateral, and the nail head 602 is also quadrilateral. The 11 fan-shaped blades 5 are sequentially placed on the round rod 601 in the order kjihgfedcba. Each fan-shaped blade 5 is designed with an arc-shaped hole 504 and a hemispherical protrusion 505 according to its placement position. The arc-shaped hole 503 of the upper layer of fan-shaped blades 5 fits onto the hemispherical protrusion 505 of the lower layer of fan-shaped blades 5.
