[0034] A rotatable puzzle board, such as Figure 2 、 Figure 5 、 Figure 6 As shown, it includes a rotating disk 1, and the rotating disk 1 can choose a rectangular structure or a square structure. The lower end of the rotating disk 1 is provided with a fixed disk 2, and the rotating disk 1 can rotate freely on the top of the fixed disk 2. The circumferential edge end of the fixed disk 2 is fixedly connected to a positioning ring 3, and the top middle part of the positioning ring 3 is provided with an annular limiting groove 4. The inner and outer ends of the positioning ring 3 are respectively provided with a plurality of mutually corresponding positioning grooves 5, and every two mutually corresponding positioning grooves 5 form a group, and the positioning grooves 5 are arranged on the inner and outer sides of the annular limiting groove 4. (The position of the positioning groove 5 is shown in FIG. Figure 5As shown), a rolling column 6 is rotatably installed between each group of annular limit grooves 4, and a rolling shaft 7 is coaxially fixedly connected to each rolling column 6. Each rolling shaft 7 is rotatably installed in the positioning groove 5, and a plurality of annular cover plates 8 are provided on the positioning ring 3. The annular cover plates 8 can prevent the rolling shaft 7 from escaping from the positioning groove 5 during rotation, and the plurality of annular cover plates 8 can be combined into a ring shape.

[0035] like Figure 5 、 Figure 7 As shown, the positioning ring 3 is provided with a plurality of snap-in holes 9 that pass through from top to bottom, and each snap-in hole 9 is respectively arranged on the inner side and the outer side of the annular limiting groove 4, and each of the bottom ends of the annular cover plate 8 is respectively fixedly connected with a clamping block 10, and the bottom end of each clamping block 10 is respectively fixedly connected with a blocking block, and the blocking block is arranged toward the annular limiting groove 4, and the angle between the blocking block and the clamping block 10 is 90 degrees. The clamping block 10 is made of existing elasticity, and each of the clamping blocks 10 is respectively installed in the corresponding snap-in hole 9, and the blocking block is clamped on the bottom surface of the positioning ring 3. (The installation method of the clamping block 10 and the blocking block is as shown in the figure) Figure 7 shown).

[0036] like Figure 5 、 Figure 10 As shown, a central shaft 11 is fixedly connected to the center of the top of the fixed disk 2 , a blocking shaft 12 is coaxially fixedly connected to the top of the central shaft 11 , and a contact shaft 13 is coaxially fixedly connected to the top of the blocking shaft 12 .

[0037] like Figure 5 、 Figure 9 As shown, each of the annular cover plates 8 is respectively provided with a plurality of annular holes 14 passing through it from top to bottom. The specifications of the annular holes 14 are larger than those of the rolling shaft 7. The rolling shaft 7 is installed in the annular holes 14. A plurality of reinforcing ribs 15 are fixedly connected to the inner wall of the annular limiting groove 4, which can improve the firmness of the positioning ring 3. An annular groove 16 is provided on the bottom surface of the rotating disk 1. The annular groove 16 is concentrically arranged with the annular limiting groove 4, and the rolling shaft 7 can roll in the annular groove 16. Cotton cloth or sponge strips are fixedly arranged on the inner wall of the annular groove 16, which can reduce the noise generated when the rolling shaft 7 moves.

[0038] like Figure 1 、 Figure 3 、 Figure 4 As shown, the top of the rotating disk 1 is connected to a placement plate 17, the thickness of the placement plate 17 is greater than the thickness of the rotating disk 1, and a placement cavity 18 is opened at the bottom of the placement plate 17. A cross reinforcement frame 19 is fixedly connected to the inner wall of the placement cavity 18, thereby dividing the placement cavity 18 into four drawer cavities. The placement cavity 18 is located above the placement plate 17, and the cross reinforcement frame 19 can enhance the stability and firmness of the placement plate 17.

[0039] like Figure 3 As shown, a drawer box 20 is slidably connected to the interior of each drawer cavity, and a puzzle cavity 21 is provided on the top surface of the placement plate 17. Limiting bars are fixedly connected around the puzzle cavity 21 to prevent puzzle pieces from falling.

[0040] like Figure 2 As shown, the rotating disk 1 and the cross reinforcement frame 19 are connected by a plurality of screws 22 , thereby improving the firmness between the rotating disk 1 and the cross reinforcement frame 19 .

[0041] like Figure 2 、 Figure 5 As shown, a shaft hole 23 is provided at the bottom of the rotating disk 1, and a positioning hole is provided in the middle of the cross reinforcement frame 19. The positioning hole and the shaft hole 23 are arranged correspondingly up and down and have the same diameter. The outer diameter of the central shaft 11 is larger than the outer diameter of the blocking shaft 12, and the outer diameter of the blocking shaft 12 is larger than the outer diameter of the contact shaft 13. The outer wall circular surface of the bearing is fixedly connected to the inner wall of the positioning hole, the outer diameter of the central shaft 11 is larger than the inner diameter of the shaft hole 23, the outer diameter of the blocking shaft 12 is slightly smaller than the inner diameter of the shaft hole 23, and the outer diameter of the contact shaft 13 is slightly smaller than the center hole diameter of the bearing; when in use, the contact shaft 13 is inserted into the center hole of the bearing, at this time, the top annular surface of the blocking shaft 12 contacts the bottom surface of the bearing, and the top annular surface of the central shaft 11 contacts the bottom surface of the rotating disk 1, providing support force for the rotating disk 1, and the top surface of the rolling shaft 7 is higher than the top surface of the central shaft 11.

[0042] like Figure 2 、 Figure 5 As shown, the top surface of the positioning ring 3 is lower than the top surface of the fixed disk 2, and the distance between the positioning ring 3 and the fixed disk 2 is the same as the thickness of the annular cover 8. The specifications of the positioning ring 3 are the same as those of the annular cover 8. A plurality of friction pads 24 are fixedly connected to the bottom edge of the fixed disk 2, and the friction pads 24 are made of rubber.

[0043] During use, a person holds the fixed disk 2 and places it on the table. The friction pad 24 increases the friction of the table and improves the stability of the fixed disk 2. Each rolling column 6 is installed in the corresponding positioning groove 5, and the rolling shaft 7 can rotate in the annular limit groove 4. Then, each clamping block 10 is inserted into the corresponding clamping hole 9. Since the clamping block 10 is elastic, the blocking block at this time can contact and clamp with the bottom surface of the positioning ring 3. Repeat the above steps and install the remaining annular cover plates 8 on the top surface of the positioning ring 3. Each rolling shaft 7 is respectively located in the corresponding annular hole 14, so that the contact shaft 13 is inserted into the center hole of the bearing. At this time, the top annular surface of the blocking shaft 12 contacts the bottom surface of the bearing, the top annular surface of the center shaft 11 contacts the bottom surface of the rotating disk 1, and the rolling shaft 7 contacts the inner top surface of the annular groove 16, completing the assembly of the puzzle board.

[0044] The personnel takes out the puzzle pieces from the drawer box 20 and places them in the puzzle cavity 21 to put the puzzle together. When the area of the puzzle pieces becomes larger and the personnel's arms cannot reach the puzzle pieces on the opposite side, the personnel push the placement plate 17 to rotate, and the rolling shaft 7 rolls along the annular groove 16. At this time, the rotating disk 1 rotates with the outer ring of the bearing, and the ball rolls around the outside of the inner ring of the bearing. At the same time, the top surface of the blocking shaft 12 will rotate against the bottom surface of the bearing, and the top surface of the central shaft 11 will rotate against the bottom surface of the rotating disk 1, which can easily make the placement plate 17 rotate. Due to the provision of cotton cloth or sponge strips, the noise generated when the rolling shaft 7 rolls can be reduced. Due to the provision of the annular cover plate 8, the rolling column 6 can be blocked to prevent the rolling shaft 7 from falling off from the positioning groove 5 when rotating. At the same time, the puzzle pieces can also be prevented from falling into the drawer box 20 to avoid loss. Compared with the ball movement, the contact area between the rolling shaft 7 and the annular groove 16 is increased, which improves stability.
