AI Technical Summary
The problem of friction noise between rollers and slide rails in existing fitness equipment has not been effectively solved during use, and the noise is particularly noticeable when used for a long time and without maintenance.
The roller structure features a silent pattern design, including ring stripes on the outer wall of the rollers. This disperses contact pressure and absorbs vibration energy. Combined with the limiting design of multiple rollers and stops, it prevents the seat from detaching from the slide rail.
It effectively reduces friction noise, enhances the stability of seat sliding, reduces wear rate, extends service life, and reduces lubrication requirements.

[0015] Mark explanation:
[0016] The fitness equipment 1, the slide rail 2, the roller body 3, the seat 4, the mute pattern 31, the wheel part 32, the blocking part 33, and the bottom frame 41. Specific implementation
[0017] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.
[0018] It should be noted that in the utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like are based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the utility model and simplify the description, and are not intended to indicate or imply that the devices or elements of the utility model must have a specific orientation, and therefore cannot be understood as a limitation on the utility model.
[0019] Examples
[0020] Cooperation Figs. 1 to 3 As shown, the utility model discloses a mute roller structure, the roller is applied to the slide rail 2 of fitness equipment 1, including roller body 3, the fitness equipment 1 is equipped with slide rail 2 and seat 4, the seat 4 is slidably installed on the slide rail 2 through the roller body 3, the bottom of seat 4 is equipped with bottom frame 41, and the installation and fixing mode is preferably fixed by screw connection, the roller body 3 has at least 4, and is rotatably installed on the bottom frame 41 through the shaft, the outer wall of the roller body 3 is equipped with the mute pattern 31 in contact with the slide rail 2.
[0021] Multi-roller layout: at least four roller bodies 3 are symmetrically distributed on the bottom frame 41 of the seat 4 and are rotatably connected through the shaft, so that the load bearing balance is improved.
[0022] Through the mute pattern 31 structure of the roller body 3, the contact area with the slide rail 2 can be reduced, the contact pressure can be dispersed and the vibration energy can be absorbed, so that the noise can be effectively reduced.
[0023] The mute pattern 31 is an annular stripe and is arranged at equal intervals on the outer wall of the roller body 3. The annular stripe-shaped mute pattern is arranged on the outer wall of the roller body 3, and is arranged at equal intervals to disperse the friction stress and reduce the vibration noise.
[0024] The rolling wheel body 3 is provided with a wheel part 32 and a blocking part 33, both of which are provided with a mute pattern 31 on the surface, the wheel part 32 is in contact with the slide rail 2, and the blocking part 33 is in contact with the side wall of the slide rail 2, and the blocking part 33 of each rolling wheel body 3 cooperates to limit the seat 4 from being separated from the slide rail.
[0025] Anti-derailing structure: the rolling wheel body 3 is divided into a wheel part 32 and a blocking part 33, the wheel part 32 is in contact with the upper surface of the slide rail 2, and the blocking part 33 is in contact with the side wall of the slide rail 2, forming a three-dimensional limit to prevent the seat 4 from being separated laterally.
[0026] The rolling wheel body 3 is provided with a left-right communicating rotating shaft hole
[0027] The embodiment has the following effects:
[0028] Significant noise reduction: the mute pattern 31 reduces friction noise by dispersing contact pressure and absorbing vibration energy. Enhanced stability: multiple rolling wheels cooperatively support and combine with the blocking part to limit the deviation of the sliding track of the seat to be less than 1mm, avoiding the risk of derailing. Prolonged life: the pattern design reduces the contact surface pressure and reduces the wear rate. Maintenance-free advantage: the self-centering structure and wear-resistant material reduce the lubrication requirement, suitable for home and commercial scenes.
[0029] Taking a rowing machine as an example, the seat 4 is welded or screwed with a U-shaped chassis at the bottom, and four rolling wheel bodies 3 are installed on both sides of the chassis 41 in two groups through rotating shafts. The rolling wheel body 3 is made of polyurethane with a hardness of 80A, and the outer wall is processed with annular stripes with a depth of 0.5mm and a pitch of 2mm. The slide rail 2 is made of aluminum alloy and is surface anodized. The chassis 41 of the embodiment is provided with a U-shaped wheel frame for rotating and installing the rolling wheel body 3.
