[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-5 The present invention provides a technical solution: a composite soft walking board of a walking machine, including side frames 1 symmetrically arranged on both sides, and rollers 2 installed between the two sets of side frames 1, the rollers 2 are used to cover the running belt, and only the rear roller 2 of the walking machine is shown in the figure. An adjusting bolt 3 for adjusting the front and rear position of the roller 2 is provided at one end of the side frame 1, and the adjusting bolt 3 is used to adjust the distance between the rear roller 2 and the front roller 2. A fixed cross bar 4 for supporting a fixed base plate 502 is also provided between the two side frames 1. The above is the existing technology and will not be elaborated on.

[0026] Reference Figure 1A walking board assembly 5 is provided between the side frames 1 on both sides. The walking board assembly 5 includes a base plate 502 and a walking board body 501 arranged on the top of the base plate 502. The walking board body 501 is symmetrically arranged on both sides of the base plate 502 and is connected to the base plate 502 to form a front-to-back sliding connection. The walking board body 501 on one side is used for walking with the left foot, and the walking board body 501 on the other side is used for walking with the right foot, thereby forming a cycle; a soft layer 6 is provided on the top of the walking board body 501, and the soft layer 6 can be a rubber layer. When the running belt is collapsed by the exerciser's stepping, the soft layer 6 can increase the friction with the running belt, so that the walking board body 501 slides backward with the running belt to avoid the relative sliding friction between the running belt and the walking board body 501. A return member is provided on the base plate 502 for returning to the initial position after the walking board body 501 slides.

[0027] Specific reference Figure 2-4 A slider 7 is provided at the bottom of the walking board body 501, and a slide groove 8 is provided on the base plate 502 for the slider 7 to slide back and forth. A guide rod 9 is provided in the slide groove 8. The slider 7 is sleeved on the guide rod 9 and forms a sliding connection. The walking board body 501 can be stably slid on the base plate 502 through the cooperation of the slider 7, the slide groove 8 and the guide rod 9; a buffer pad 10 can be provided on the front inner wall of the slide groove 8 to avoid rigid impact after each return of the slider 7.

[0028] Specific reference Figure 2 , 3 The return member includes a return spring 11, which is sleeved on the guide rod 9 and is always in a compressed state. When the exerciser steps on the treadmill to drive the walking board to slide backward and lift his foot, the walking board will return to its initial position under the action of the return spring 11, ready for the next time for the exerciser to walk.

[0029] Specific reference Figure 2 The base plate 502 is horizontally penetrated with an adjustment groove 12, which is connected to the slide groove 8. An adjustment plate 13 is provided in the adjustment groove 12 for sliding back and forth. The return spring 11 is arranged between the slider 7 and the adjustment plate 13. The adjustment bolt 3 includes a bolt body 31 for adjusting the roller shaft 2, and an adjustment member 32 for adjusting the front and rear position of the adjustment plate 13. By adjusting the position of the adjustment plate 13, the compression amount of the return spring can be controlled, thereby controlling the speed at which the return spring 11 drives the slider 7 to return to one end of the slide groove 8, which can be adjusted according to the walking speed of the exerciser.

[0030] Specific reference Figure 5The adjusting member 32 includes an adjusting rod 321 rotatably connected to one end of the bolt body 31, and also includes a connecting rod 322 slidably arranged at the axial position of the bolt body 31 and the adjusting rod 321. The connecting rod 322 is a polygonal columnar structure. In this embodiment and the drawings of the specification, both sides of the adjusting plate 13 extend outwardly. The outward extension of the adjusting plate 13 is sleeved on the adjusting rod 321 and is threadedly connected with the adjusting rod 321. The bolt body 31 is axially penetrated by a first connecting groove 14 for the connecting rod 322 to slide. The adjusting rod 321 is axially penetrated by a first connecting groove 14. A second connecting groove 15 is provided for the connecting rod 322 to slide, and the bolt body 31 is used to adjust the distance between the rear roller shaft 2 and the front roller shaft 2 (existing technology). When it is necessary to rotate the adjusting rod 321 to adjust the position of the adjusting plate 13, the connecting rod 322 with a quadrilateral columnar structure can be inserted into the second connecting groove 15, and the adjusting rod 321 can be rotated. It should be noted that: after rotating the adjusting rod 321 to adjust the adjusting plate 13, the connecting rod 322 can be pulled to disengage the connecting rod 322 from the adjusting rod 321, and the reverse rotation drives the rear roller shaft 2 to return to its original position.

[0031] Specific reference Figure 5 A groove is formed at one end of the bolt body 31 , in which a bearing 16 is embedded. A convex portion 17 is formed at one end of the adjusting rod 321 , and the convex portion 17 is fixed in the inner ring of the bearing 16 .

[0032] Specific reference Figure 5 A tail plate is provided at one end of the connecting rod 322 located outside the bolt body 31, and a plurality of groups of insertion rods 18 are provided along the circumferential side of the end surface of the tail plate close to the bolt body 31. A second tail plate is provided on the side of the bolt body 31 close to the tail plate, and the second tail plate is provided with a slot 19 for inserting the insertion rod 18. In this way, the connection strength between the connecting rod 322 and the bolt body 31 can be increased.

[0033] Specific reference Figure 4 Rollers 20 are rotatably arranged at the four corners of the bottom end surface of the walking board body 501, and the rollers 20 are arranged in contact with the base plate 502. During the circular sliding process of the walking board body 501, the rollers 20 can play a supporting role, so that the walking board body 501 slides more smoothly.

[0034] A specific application example of this embodiment is:

[0035] When the device is in use, when an exerciser walks on the treadmill belt, the weight of the exerciser will cause the treadmill belt to sag, and when the treadmill belt sags, it will contact the walking board body 501. When the exerciser pushes backward, the walking board body 501 will move backward with the treadmill belt. After the exerciser lifts his foot, the walking board body 501 will return to the initial position under the action of the return spring, ready for the next walking by the exerciser.
