Description

Technical Field

[0001] This utility model relates to a fitness board, specifically a foldable fitness board. Background Technology

[0002] Exercise boards, as a type of home or portable fitness equipment, have become increasingly popular in recent years due to their convenience and versatility. Various exercises on exercise boards, such as push-ups, sit-ups, and planks, effectively train the muscles in the abdominal, back, and pelvic areas, thereby strengthening core strength. By performing exercises at different angles and in different postures on the exercise board, joint mobility can be increased, reducing stiffness. High-intensity exercises on the exercise board, such as rapid push-ups and jumps, can quickly burn calories, aiding in weight loss and body shaping. Consistent practice can also sculpt muscle definition, making the body more toned.

[0003] Current fitness boards are typically designed to be lightweight and easy to fold, making them convenient to carry and store. This makes them ideal fitness equipment for homes or offices, as they are not limited by time or space. However, these fitness boards are usually connected by pivots, hinges, or other structures. When folded, the two sides of the boards are difficult to align, making them easy to wobble and inconvenient to carry. In addition, when unfolded, each side can easily rotate, which is not conducive to use. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a foldable fitness board.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a foldable fitness board, comprising a left board body and a right board body, with fixing plates provided on the front and rear sides of opposite ends of the left and right board bodies, and arc-shaped tooth structures provided on the outer edges of each fixing plate, with hollowed-out rotating connection holes provided in the center of each fixing plate, and a connecting plate provided on the outer side of the fixing plates on the same side of the left and right board bodies, with connecting cylinders perpendicular to the connecting plate body provided at both ends of the inner side of each connecting plate near the fixing plate, and the connecting cylinders at both ends of each connecting plate passing through and fixed in the rotating connection holes of the fixing plates on the same side, so that adjacent tooth structures mesh together.

[0006] Furthermore, each connecting cylinder has multiple evenly arranged barb structures at its outer end. The outer diameter of the barb structure is larger than the inner diameter of the rotating connecting hole. After each connecting cylinder passes through the rotating connecting hole of the connecting plate, the barb part of the barb structure is in close contact with the surface of the connecting plate.

[0007] Furthermore, the sidewall of the connecting cylinder between the barbed structures is provided with multiple long strip-shaped notches arranged along the axis of the connecting cylinder.

[0008] Furthermore, the surfaces of the left and right plates are respectively provided with downward-recessed circular fixing pits.

[0009] Furthermore, the outer edges of the left and right plates are bent downwards to form reinforced outer edges.

[0010] Furthermore, the tops of the front and rear fixing plates of the same plate are fixedly connected by a tile-shaped plate.

[0011] Furthermore, it also includes a pair of arched support handrails, with the column structures at both ends of each support handrail being inserted into a pair of circular fixing recesses on the plate.

[0012] Furthermore, the inner side of the middle part of each tile-shaped plate is also fixed with a reinforcing plate structure for fixed connection with the corresponding plate body.

[0013] Furthermore, a circular positioning hole is provided at the outer end of the column structure, and a positioning post corresponding to the circular positioning hole is provided at the bottom of each circular fixing recess.

[0014] When this utility model is folded, the left and right plates are rotatably connected by a connecting plate and a connecting cylinder, causing the adjacent toothed structures to mesh together. Thus, when one side of the plate is rotated, the meshing toothed structures form a synchronous driving structure, causing the other side of the plate to fold simultaneously. This achieves synchronous folding and opening of the left and right plates, making them not only more secure and easier to carry after folding, but also more stable when unfolded and used for support, better meeting the needs of exercise and fitness.

[0024] Example 1

[0025] like Figure 1-3 As shown in Figures 5-6, a folding fitness board includes a left board body 1 and a right board body 2. Fixing plates 3 are provided on the front and rear sides of opposite ends of the left and right board bodies 1 and 2. Each fixing plate 3 has a hollowed-out rotating connection hole 5 at its center. A connecting plate 6 is provided on the outer side of the fixing plates 3 on the same side of the left and right board bodies 1 and 2. The outer edges of each fixing plate 3 are semi-circular, and adjacent semi-circular edges may or may not contact each other. Connecting cylinders 7 perpendicular to the body of the connecting plate 6 are provided at both ends of the inner side of each connecting plate 6 near the fixing plate 3. The ends of the connecting plate 6 are semi-circular, which facilitates the rotation and opening of the left and right board bodies 1 and 2. The connecting cylinders 7 at both ends of each connecting plate 6 are fixed through and fixed in the rotating connection hole 5 of the fixing plate 3 on the same side. The left and right board bodies 1 and 2 can be rectangular, square, elliptical, or other shapes, and their corners can be rounded.

[0026] The specific connection structure of the connecting plate 6: Each connecting cylinder 7 has multiple evenly arranged barb structures 8 at its outer end. The outer diameter of the barb structure 8 is larger than the inner diameter of the rotating connecting hole 5. After each connecting cylinder 7 passes through the rotating connecting hole 5 of the connecting plate 6, the barb part of the barb structure 8 is tightly attached to the surface of the connecting plate 6. The side wall of the connecting cylinder 7 between the barb structures 8 is provided with multiple long strip-shaped notches 9 arranged along the axis of the connecting cylinder 7, which facilitates the shrinking of the barb structure 8 when plugging and fixing. This structure is not only easy to process and low in cost, but also can be plugged in during assembly without the need for screws and bolts, making the fixing connection more convenient and quick.

[0027] To facilitate the insertion of the support handrail 13, the surfaces of the left plate 1 and the right plate 2 are respectively provided with downwardly recessed circular fixing recesses 10, and also include a pair of arched support handrails 13. The column structures 14 at both ends of each support handrail 13 can be inserted into the pair of circular fixing recesses 10 on the plate. The outer end of the column structure 14 is provided with a circular positioning hole 16, and the bottom of each circular fixing recess 10 is provided with a positioning post 17 corresponding to the circular positioning hole 16.

[0028] To ensure the overall structural strength, the outer edges of the left plate 1 and the right plate 2 are bent downward to form a reinforcing outer edge 11, and the tops of the front and rear fixing plates 3 of the same plate are fixedly connected by a tile-shaped plate 12.

[0029] The working principle of this embodiment is as follows: When folding, simply fold the left plate 1 and the right plate 2 in half.

[0030] Example 2

[0031] This embodiment provides a foldable fitness board; please refer to the accompanying drawings in the instruction manual. Figure 1-5 .

[0032] like Figure 1-5As shown, a folding fitness board includes a left board body 1 and a right board body 2. Fixing plates 3 are provided on the front and rear sides of opposite ends of the left and right board bodies 1 and 2. The outer edges of each fixing plate 3 are semi-circular structures, and each fixing plate 3 has arc-shaped toothed structures 4 on its outer semi-circular edges. A hollowed-out rotating connection hole 5 is provided in the center of each fixing plate 3. A connecting plate 6 is provided on the outer side of the fixing plates 3 on the same side of the left and right board bodies 1 and 2. Each connecting plate 6 has connecting holes perpendicular to its body at both ends near the inner surface of the fixing plates 3. The cylinder 7 and the connecting plate 6 are semi-circular at both ends, which facilitates the rotation and opening of the left plate 1 and the right plate 2. The connecting cylinders 7 at both ends of each connecting plate 6 are respectively fixed in the rotating connecting holes 5 of the fixed plate 3 on the same side, so that the adjacent toothed structures 4 are engaged together. The toothed structures 4 are set at one corner of the fixed plate 3, so that they can only be engaged and rotated at this part, thus forming a limit, so that the left plate 1 and the right plate 2 can only rotate 90°. The left plate 1 and the right plate 2 can be rectangular, square, elliptical, etc., and the corners of the left plate 1 and the right plate 2 can be rounded.

[0033] The specific connection structure of the connecting plate 6: Each connecting cylinder 7 has multiple evenly arranged barb structures 8 at its outer end. The outer diameter of the barb structure 8 is larger than the inner diameter of the rotating connecting hole 5. After each connecting cylinder 7 passes through the rotating connecting hole 5 of the connecting plate 6, the barb part of the barb structure 8 is tightly attached to the surface of the connecting plate 6. The side wall of the connecting cylinder 7 between the barb structures 8 is provided with multiple long strip-shaped notches 9 arranged along the axis of the connecting cylinder 7, which facilitates the shrinking of the barb structure 8 when plugging and fixing. This structure is not only easy to process and low in cost, but also can be plugged in during assembly without the need for screws and bolts, making the fixing connection more convenient and quick.

[0034] To facilitate the insertion of the support handrail 13, the surfaces of the left plate 1 and the right plate 2 are respectively provided with downwardly recessed circular fixing recesses 10, and also include a pair of arched support handrails 13. The column structures 14 at both ends of each support handrail 13 can be inserted into the pair of circular fixing recesses 10 on the plate. The outer end of the column structure 14 is provided with a circular positioning hole 16, and the bottom of each circular fixing recess 10 is provided with a positioning post 17 corresponding to the circular positioning hole 16.

[0035] To ensure the overall structural strength, the outer edges of the left plate 1 and the right plate 2 are bent downward to form a reinforcing outer edge 11. The tops of the front and rear fixing plates 3 of the same plate are fixedly connected by a tile-shaped plate 12. The inner side of the middle part of each tile-shaped plate 12 is also fixed with a reinforcing plate structure 15 for fixed connection with the corresponding plate.

[0036] The working principle of this embodiment is as follows: When folding, the left plate 1 and the right plate 2 are rotatably connected by the connecting plate 6 and the connecting cylinder 7, so that the adjacent toothed structures 4 are engaged together. When one side of the plate is rotated, the meshing toothed structures 4 form a synchronous driving structure, which causes the other side of the plate to fold at the same time. This achieves the synchronous folding and opening of the left plate 1 and the right plate 2. Not only is it more secure and easier to carry after folding, but it is also more stable when unfolded and used for support, which better meets the needs of exercise and fitness.

[0037] Of course, the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
