[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The present embodiment is described in detail below with reference to the accompanying drawings:

[0029] This embodiment provides a multifunctional fitness board. Please refer to the accompanying drawings in the specification. Figure 1-10 .

[0030] like Figure 1-10 As shown, a multifunctional fitness board comprises a bottom plate 1 and a sliding plate 2. The sliding plate 2 is arranged on a track 3 of the bottom plate 1 and can reciprocate along the track 3. An elastic component is fixed inside the bottom plate 1. One end of the elastic component is fixedly connected to the structure inside the bottom plate 1, and the other end is fixedly connected to the sliding plate 2, so that the resistance encountered by the sliding plate 2 when moving from the starting position gradually increases;

[0031] Specifically: the sliding plate 2 is located at one end of the base plate 1, the elastic component is an elastic rubber band 4, a first reversing wheel 5 that can rotate freely is arranged inside the bottom of the base plate 1 near one end of the sliding plate 2, and a second reversing wheel 6 that can rotate freely is arranged inside the bottom of the base plate 1 away from the end. The elastic rubber band 4 starts from the fixed end in the base plate 1, and successively passes around the second reversing wheel 6 and the first reversing wheel 5 in an S shape and is fixedly connected to the sliding plate 2. In this way, when the sliding plate 2 moves from the starting position, the sliding plate 2 gradually stretches the elastic rubber band 4, and when the elastic rubber band 4 is stretched, it drives the second reversing wheel 6 and the first reversing wheel 5 to rotate, and the second reversing wheel 6 and the first reversing wheel 5 play a good guiding role, and the more the elastic rubber band 4 is stretched, the greater the resistance it encounters; of course, the elastic component can also be a tension spring, but the fixing method and position are different. Of course, other elastic components can also be used. The pulling of the tension spring will produce a certain noise, and it is preferred to use an elastic rubber band 4.

[0032] In order to facilitate the adjustment of the strength of the entire elastic component, thereby adjusting the resistance strength of pushing the sliding plate 2 according to different groups of people, the elastic component also includes an adjusting threaded rod 7, which is arranged in a slideway 8 of the extension line of the fixed end of the elastic rubber band 4 in the base plate 1, and an adjusting nut 9 is also arranged at the fixed end of the elastic rubber band 4 in the base plate 1. One end of the adjusting threaded rod 7 is meshed with the internal thread of the adjusting nut 9, and the adjusting nut 9 is fixed in the adjusting slider 10. The adjusting slider 10 is located in the slideway 8 and can slide along the slideway 8. The other end of the adjusting threaded rod 7 is provided with a bolt head and extends to the end of the base plate 1. The bolt head is supported and fixed by the supporting ribs 11 in the slideway 8. When the adjusting threaded rod 7 is rotated, the adjusting slider 10 can be driven to move through the limit of the slideway 8. By moving the adjusting slider 10, such as moving toward the bolt head, the tensioning effect on the elastic rubber band 4 is achieved, so that the inspiration force when the sliding plate 2 is moved again will also increase, which is equivalent to adjusting the intensity of training according to different groups of people.

[0033] In order to prevent the sliding plate 2 from falling off the bottom plate 1, a limit slider 12 is fixed to the bottom of the sliding plate 2, and a limit plate 13 protruding from the limit slider 12 body is provided on the lower surface of the limit slider 12, and the limit plate 13 and the lower surface of the limit slider 12 are sleeved on the corresponding edges of each side of the track 3, and the lower surface of the limit slider 12 is fixedly connected to the elastic rubber band 4 through a clamping head structure 14;

[0034] The lower surface of the sliding plate 2 is supported on the bottom plate 1 by a plurality of supporting pulleys 15. The surface of the bottom plate 1 through which the supporting pulleys 15 pass is provided with an inwardly concave pulley groove 16. The sliding support by the supporting pulleys 15 can not only effectively reduce the friction force when the sliding plate 2 moves, but also move more smoothly and with less noise, achieving a silent effect when in use;

[0035] The sliding plate 2, elastic component and track 3 of the base plate 1 are symmetrically arranged on the left and right, and the left and right sliding plates 2 are fixedly connected by a fixing rod 17. The symmetrical structure can place both hands for better exercise and use; the base plate 1 is composed of two front and back parts, and a rotating hinge 18 is arranged on the lower surface of the middle part to rotatably connect the two base plates 1 together, so that one of the base plates 1 is rotated along the rotating hinge 18 and folded to the lower surface of the other part, that is, the base plate 1 is foldable, which is convenient for carrying and folding during transfer; the surface of the base plate 1 is provided with a plurality of inwardly concave groove structures 19, the edge of the base plate 1 is bent downward, and the lower surface of the base plate 1 is provided with a plurality of reinforcing rib structures, and the bottom surface of the base plate 1 is covered with a cover plate 21, so that the strength of the entire base plate 1 is sufficient to ensure use, and one end of the sliding plate 2 is fixed with a handle 20 bent upward for easy hand-holding.

[0036] Of course, the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
