[0002] In the field of sports fitness equipment, treadmills are one of the most commonly used fitness equipment. Treadmills usually have a running board, which is a support body used to support runners in running activities. The treadmill belt usually moves on the running board, and the runners stand on the running board through the belt. When the belt moves, the runners have to keep on the running board by running.

[0003] The existing treadmill base is usually placed on the ground through a base, and its inclination angle cannot be adjusted, which cannot meet the user's needs, thereby reducing the user's comfort. At the same time, the treadmill will generate noise when in use. Part of the noise comes from the collision of the exerciser's feet with the running belt and the running board every time the exerciser steps on the ground. Each time the foot steps on the ground, an impact noise is generated. In addition, the friction between the running belt and the running board will suddenly increase when stepping on the ground, which can easily cause friction damage between the running belt and the running board, thereby reducing the service life.

[0004] Therefore, it is particularly important to design a treadmill running board comfort adjustment device to solve the above-mentioned defects. Utility Model Content

[0011] As a preferred solution of the present invention, multiple groups of rollers are located on the inner side of the running board body at equal intervals, and the surfaces of the multiple groups of rollers are in contact with the inner side of the treadmill belt. The left and right sides of the running board body are rotatably connected to multiple groups of rollers, and the base is provided with roller grooves adapted for use with the multiple groups of rollers.

[0012] As a preferred solution of the present invention, the buffer mechanism includes support plates fixedly installed on the left and right ends of the bottom of the running board body, the bottoms of multiple groups of the support plates are fixedly connected to support seats, the bottoms of multiple groups of the support seats are fixedly connected to first buffer springs, the front and rear sides of the support seats are rotatably connected to transmission rods, the bottoms of two groups of transmission rods are rotatably connected to slides, the sides of the two groups of slides that are away from each other are fixedly connected to second buffer springs, and the ends of the two groups of second buffer springs that are away from each other are fixedly connected to the inner side wall of the base through a fixed plate.

DETAILED DESCRIPTION

[0024] The following will combine 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, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Example:

[0026] See also Figures 1-6 , the utility model provides a technical solution:

[0027] A treadmill running board comfort adjustment device includes a base 1, handrail frames 2 are fixedly installed on the left and right ends of the top of the base 1, adjustment mechanisms 3 are installed on the front and rear ends of the bottom of the base 1, a buffer cavity 4 is opened on the inner side of the base 1, a running board body 5 is movably installed on the inner side of the buffer cavity 4, a running belt 6 is installed on the outer side of the running board body 5, and multiple groups of rollers 7 are rotatably connected to the inner side of the running board body 5. Multiple groups of buffer mechanisms 8 are installed inside the base 1 and at the left and right ends of the bottom of the running board body 5.

[0028] First, the outer sides of the two groups of handrails 2 are fixed with a first rubber anti-slip cover 201, and a control console 202 is fixedly installed between the front ends of the two groups of handrails 2. When running, the user can use the handrails 2 on the left and right sides for protection, and at the same time, the user can hold the handrails 2 when exhausted. The first rubber anti-slip cover 201 on the outer side of the handrails 2 can prevent the hands from slipping and causing danger, and control is performed through the control console 202.

[0029] Furthermore, the adjustment mechanism 3 includes an adjustment frame 301 rotatably connected to the front and rear ends of the bottom of the base 1, and the front and rear ends on the left and right sides of the base 1 are fixedly connected to the first connection frame 302, and the inner sides of multiple groups of first connection frames 302 are rotatably connected to the hydraulic cylinders 303, and the output ends of the multiple groups of hydraulic cylinders 303 are rotatably connected to the adjustment frame 301 through the second connection frame 304. When the hydraulic cylinders 303 on the left and right sides of the base 1 are started, the adjustment frame 301 can be pushed up under the connection of the first connection frame 302 and the second connection frame 304. By manipulating the hydraulic cylinder 303 at the front end or the rear end of the bottom of the base 1, the adjustment frame 301 can support the front end or the rear end of the base 1, so that the inclination angle of the running board body 5 can be flexibly adjusted according to the needs of the user, and then the comfort of the running board body 5 can be adjusted.

[0030] Then, the inner sides of the two groups of adjustment frames 301 are fixedly connected with reinforcement rods 305, and the left and right sides of the bottom ends of the two groups of adjustment frames 301 are fixedly connected with second rubber anti-slip sleeves 306. The reinforcement rods 305 are used to strengthen the structure of the adjustment frames 301 so that its strength can support the base 1. At the same time, when the adjustment frames 301 support the base 1, the second rubber anti-slip sleeves 306 can prevent the bottom of the adjustment frames 301 from sliding.

[0031] Furthermore, multiple groups of rollers 7 are evenly spaced on the inner side of the running board body 5, and the surfaces of the multiple groups of rollers 7 are in contact with the inner side of the treadmill 6. The left and right sides of the running board body 5 are rotatably connected to multiple groups of rollers 501. The base 1 is provided with rolling grooves 502 adapted for the multiple groups of rollers 501. When the user steps on the treadmill 6, the multiple groups of rollers 7 assist in rolling, thereby avoiding damage to the treadmill 6 and the running board body 5 due to direct friction, thereby increasing the service life of the treadmill 6 and the running board body 5. At the same time, when stepping on, the multiple groups of rollers 501 roll on the inner side of the rolling groove 502, and the running board body 5 moves up and down with the stepping and is buffered by the buffer mechanism 8, thereby reducing the noise generated by the stepping.

[0032] Secondly, the buffer mechanism 8 includes support plates 801 fixedly mounted on the left and right ends of the bottom of the running board body 5, the bottoms of multiple groups of support plates 801 are fixedly connected to support seats 802, the bottoms of multiple groups of support seats 802 are fixedly connected to first buffer springs 803, the front and rear sides of the support seats 802 are rotatably connected to transmission rods 804, the bottoms of the two groups of transmission rods 804 are rotatably connected to slides 805, the sides of the two groups of slides 805 that are away from each other are fixedly connected to second buffer springs 806, and the ends of the two groups of second buffer springs 806 that are away from each other are fixedly connected to the inner side wall of the base 1 through fixed plates 807. When the user steps on the tread belt 6, the running board body 5 is subjected to force and the support plate 801 moves downward accordingly, causing the first buffer spring 803 at the bottom of the support seat 802 to contract accordingly. At the same time, under the transmission of the two groups of transmission rods 804, the two groups of slides 805 are squeezed, causing the second buffer springs 806 to be squeezed accordingly, thereby buffering the user's stepping force and reducing the noise generated.

[0033] Finally, a slider 808 is fixedly connected to the bottom of the slide 805, and a slide groove 809 adapted for use with the slider 808 is opened at the bottom end of the base 1. When the slide 805 slides, the slider 808 assists in sliding on the inside of the slide groove 809, thereby improving the stability of the slide 805 when moving.

[0034] In this embodiment, the implementation scenario is specifically as follows: when the user is running, the user uses the handrails 2 on the left and right sides for protection, and can hold the handrails 2 when exhausted, and start the hydraulic cylinders 303 on the left and right sides of the base 1. Under the connection of the first connecting frame 302 and the second connecting frame 304, the adjustment frame 301 can be pushed up, and by manipulating the hydraulic cylinder 303 at the front end or the rear end of the bottom of the base 1, the adjustment frame 301 can support the front end or the rear end of the base 1, so as to flexibly adjust the inclination angle of the running board body 5 according to the user's needs, and then adjust the comfort of the running board body 5. When the user steps on the treadmill 6, multiple groups of rollers 7 assist in rolling, thereby avoiding direct friction between the treadmill 6 and the treadmill body 5 and damaging it, thereby improving the connection between the treadmill 6 and the treadmill body 5, and at the same time, when stepping on, multiple groups of rollers 501 roll on the inner side of the rolling groove 502. After the running board body 5 is subjected to force, the support plate 801 moves downward, causing the first buffer spring 803 at the bottom of the support seat 802 to move downward and contract. At the same time, under the transmission of the two groups of transmission rods 804, the two groups of slide seats 805 are squeezed, so that the second buffer spring 806 is squeezed accordingly, thereby buffering the user's stepping force and reducing the noise generated. The entire operation process is simple and convenient. Compared with the existing treadmill running boards, the utility model can flexibly adjust the inclination angle of the running board body 5 according to the user's needs through design, thereby adjusting the comfort of the running board body 5, and at the same time can improve the service life of the treadmill belt 6 and the running board body 5, and buffer the user's stepping and reduce the noise generated.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
