DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] Embodiment 1

[0029] like Figures 1 to 3 As shown, the utility model provides a sole with adjustable elastic force, comprising: a sole 100, a support member 310, an elastic member 500, an adjusting member 400 and a bracket 200; the sole 100 is provided with at least one accommodating space 110, the bottom of the sole 100 is provided with an opening 120 connected to the accommodating space 110, the bracket 200 is fixedly connected in the accommodating space 110, the adjusting member 400 is connected to the bracket 200 in a manner that it can move up and down, the adjusting member 400 is provided with a first through hole 430 in the vertical direction, and the bottom of the support member 310 is fixedly connected with a movable rod 320, the movable rod 320 is movably arranged in the first through hole 430, the support member 310 is in contact with the top wall of the accommodating space 110, the elastic member 500 is arranged between the support member 310 and the adjusting member 400, and the adjusting member 400 is controlled to move up and down from the opening 120. When the adjusting member 400 moves up and down, the compression amount of the elastic member 500 is controlled. During use, the adjusting member 400 is operated from the opening 120 to move the adjusting member 400 in the vertical direction, and the compression amount of the elastic member 500 above the adjusting member 400 can be adjusted. When the top of the support member 310 is subjected to force, the movable rod 320 moves downward along the first through hole 430, and the elastic member 500 is compressed. The cooperation between the movable rod 320 and the first through hole guides the movement of the support member 310.

[0030] The bracket 200 is connected to the side wall of the accommodating space 110 by glue, and a threaded hole 220 is opened on the bracket 200. An adjustment cavity 210 for operating the adjustment member 400 is arranged below the threaded hole 220. In this embodiment, the outer structure of the bracket 200 is a hollow cylinder without a bottom, and the threaded hole 220 is opened at the top of the bracket 200.

[0031] The outer wall of the adjusting member 400 is provided with a threaded section 420, and the adjusting member 400 is threadedly connected to the threaded hole 220. When the adjusting member 400 is rotated, the adjusting member 400 moves in the vertical direction, thereby changing the compression amount of the elastic member 500. In actual use, the elasticity of the elastic member 500 can be adjusted according to different body weights and usage scenarios, and the support and shock absorption performance of the shoe can be changed to meet various usage requirements.

[0032] An adjusting section 410 for rotating the adjusting member 400 is further provided below the threaded section 420 of the adjusting member 400. In this embodiment, the adjusting section 410 is cylindrical and has anti-slip textures on its surface. In other embodiments, the adjusting member 400 may be polygonal, or a polygonal hole may be provided at the end of the adjusting member 400, so that the adjusting member 400 may be conveniently rotated using a wrench or other tools.

[0033] An adjusting disk 600 is arranged on the adjusting member 400, and the movable rod 320 passes through the adjusting disk 600. The elastic member 500 is arranged on the adjusting disk 600 to prevent the elastic member 500 from rotating with the adjusting member 400 when the adjusting member 400 is rotated. When the adjusting member 400 moves up or down, the adjusting disk 600 moves up or down with the adjusting member 400. In this embodiment, the elastic member 500 adopts a spring, and its preferred size is a wire diameter of 1mm, an outer diameter of 12mm, a free length of 25mm, and a total number of turns of 3 turns. The spring of this specification has moderate elastic force, good performance, can adapt to a variety of usage scenarios, and is easy to install and adjust.

[0034] When the sole 100 is under pressure, the pressure is transmitted to the support member 310 in the accommodating space 110. The support member 310 is forced to drive the movable rod 320 to move downward, and the spring between the support member 310 and the adjustment plate 600 is compressed. When the adjustment member 400 moves upward, the greater the initial compression of the elastic member 500, the smaller the deformation range of the elastic member 500 after the sole 100 is under pressure, and the smaller the elastic force; when the adjustment member 400 moves downward, the smaller the initial compression of the elastic member 500, the larger the deformation range of the elastic member 500 after the sole 100 is under pressure, and the greater the elastic force.

[0035] Embodiment 2

[0036] like Figures 7-8As shown, the difference between this embodiment and the first embodiment is that: the adjusting member 400 is provided with a mounting groove 440 for mounting the elastic member 500. During use, one end of the spring is connected to the bottom of the support member 310, and the other end is connected to the mounting groove 440. The outer wall of the adjusting member 400 is provided with a threaded section 420. When the adjusting member 400 is rotated to move the adjusting member 400 upward, the spring is compressed to a large extent, the spring has a small deformable range, and the elastic force of the shoe is small; when the adjusting member 400 is moved downward, the spring is compressed to a small extent, the spring has a large deformable range, and the elastic force of the shoe is large. The spring is installed in the mounting groove 440 so that it is not easy to move out of place, and the mounting groove 440 also has a certain guiding effect.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
