Description

Technical Field

[0001] The utility model relates to the technical field of exercise equipment, in particular to a base for a sitting forward bend device and a sitting forward bend device. Background Art

[0002] Sit And Reach is a physical health test item in primary, middle and high schools. Its test purpose is to measure the possible range of motion of joints such as the trunk, waist, and hips in a static state, mainly reflecting the extensibility and elasticity of the joints, ligaments and muscles in these parts, as well as the development level of the body's flexibility quality.

[0003] As Figure 1 shown, the existing sitting forward bend equipment mainly includes a base and a measuring device at the top. The base is composed of a bottom plate 1, two inclined plates 2 and a vertical plate 3. The bottom plate 1, the inclined plates 2 and the vertical plate 3 are assembled and matched through snap connection. During assembly, if the convex part 4 below the inclined plate 2 is first inserted into the first bottom plate hole 6 of the bottom plate 1, it is very difficult to assemble the vertical plate 3 together. Because the cooperation between the convex part 4 above the inclined plate 2 and the vertical plate hole 8 of the vertical plate 3, and the cooperation between the convex part 4 below the vertical plate 3 and the second bottom plate hole 7 of the bottom plate 1 interfere with each other and affect each other, it is very difficult to achieve simultaneous plug-in cooperation.

[0004] If the cooperation between the convex part 4 above the inclined plate 2 and the vertical plate hole 8 is first carried out, and then the convex part 4 of the vertical plate 3 is inserted into the second bottom plate hole 7 by force extrusion. This is not only inconvenient for assembly and disassembly, but also easily causes damage to each component.

[0005] If the two inclined plates 2 are first assembled to the vertical plate 3, and then the three are integrally inserted into the bottom plate 1. At this time, it is necessary to hold the combined positions of the two inclined plates 2 and the vertical plate 3 with both hands respectively, otherwise the separation between the inclined plate 2 and the vertical plate 3 is likely to occur, resulting in the inability to integrally insert into the bottom plate 1. Moreover, when holding the whole composed of the inclined plate 2 and the vertical plate 3 with both hands, since there are many positions to be inserted between the whole and the bottom plate 1, it is impossible to accurately insert the convex parts 4 of the two inclined plates 2 and the convex part 4 of the vertical plate 3 into the bottom plate 1 simultaneously and accurately. Therefore, during the process of integrally inserting into the bottom plate 1, both hands not only need to hold the connection positions of the two inclined plates 2 and the vertical plate 3 respectively, but also need to use hands to adjust the insertion position of the whole bottom with the bottom plate 1, which is very cumbersome and extremely inconvenient.

[0006] In summary, the existing sitting forward bend equipment has the problem that the assembly and disassembly processes are too complicated. Moreover, during the whole process, if the operation sequence is improper, it is easy for the assembler to force the assembly by pulling and tugging, resulting in damage to the components.
