Description

Technical Field

[0001] The utility model relates to the technical field of rollers, in particular to a roller support assembly. Background Art

[0002] The roller in a treadmill supports and drives the running belt. When the motor rotates the roller, it interacts with the running belt through bearings, allowing the runner to run or walk on the belt. Treadmill rollers are typically made of stainless steel, a corrosion- and wear-resistant material that ensures stability and durability over extended use.

[0003] The treadmill roller is usually set on the support assembly. The existing roller support assembly does not have an adjustment function, so the support height cannot be changed. The exercise effect and running experience during use cannot reach the best. In addition, the support assembly will be greatly impacted during running, which not only has a rebound impact on the user's joints, but also reduces the service life of the assembly.

[0027] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0028] Example 1

[0029] Combined with attachment Figure 1 、 Figure 2 、 Figures 4 to 6As shown, a roller support assembly includes a base 1, on which support assemblies are symmetrically arranged, and a roller body 2 is connected between the two support assemblies. A group of the support assemblies includes a vertical tube 3 fixed on the base 1, a telescopic rod 4 is slidably inserted in the vertical tube 3, a shock-absorbing airbag 5 is connected to the top of the telescopic rod 4, and a connecting seat 6 is provided on the shock-absorbing airbag 5. A sleeve 7 is provided on one side of the outer wall of the vertical tube 3, and a fixing rod 8 is inserted in the sleeve 7. The telescopic rod 4 is provided with a plurality of equidistant fixing grooves 9 that match the fixing rod 8, and a connecting plate 10 is provided on the fixing rod 8. The connecting plate 10 is slidably arranged in the sleeve 7, and a reset spring 11 is connected to the connecting plate 10, and one end of the reset spring 11 is connected to the vertical tube 3.

[0030] Through the above structure, the telescopic rod 4 slides in the vertical tube 3, and the fixing rod 8 is inserted into the fixing groove 9 to fix the position of the telescopic rod 4 to achieve adjustment of the support height. The shock-absorbing airbag 5 can absorb vibration during use and play a buffering role to reduce the rebound impact force received by the user and improve the comfort of use.

[0031] Combined with attachment Figure 3 and Figure 6 As shown, an air pump 12 is fixedly provided on the base 1, an air supply pipe 13 is connected to the air pump 12, one end of the air supply pipe 13 is connected to the shock-absorbing airbag 5, limiting grooves 25 are symmetrically provided in the vertical pipe 3, and a slide plate 24 that cooperates with the limiting groove 25 is provided on the telescopic rod 4, and the slide plate 24 slides in the limiting groove 25.

[0032] Through the above structure, the air pump 12 is used to inflate or deflate to adjust the hardness and shock absorption effect of the shock-absorbing airbag 5. The limiting groove 25 limits the movement range of the slide plate 24, thereby limiting the height adjustment range of the telescopic rod 4.

[0033] Example 2

[0034] On the basis of embodiment 1, combined with the attached Figure 6 and Figure 7 As shown, a pressure piece 14 is connected to the connecting seat 6, and a slide groove 15 is symmetrically provided in the connecting seat 6. A slide rod 16 is connected to the pressure piece 14, and the slide rod 16 is inserted in the slide groove 15. One end of the slide rod 16 located in the slide groove 15 is provided with a fixed plate 17, and telescopic springs 18 are respectively connected to the fixed plate 17 on both sides of the slide rod 16. One end of the telescopic spring 18 is connected to the top surface of the slide groove 15. The contact surface of the pressure piece 14, the connecting seat 6 and the roller body 2 is an arc-shaped surface structure, and a rubber pad 19 is adhered to the arc-shaped surface. A number of anti-slip strips 20 surround the surface of the roller body 2. A telescopic baffle 21 is rotatably provided on the pressure piece 14, and a clamping piece 22 is provided on the connecting seat 6. The telescopic end of the telescopic baffle 21 is provided with a clamping groove 23 adapted to the clamping piece 22.

[0035] Through the above structure, the pressure piece 14 can change the distance between it and the connecting seat 6 under the action of the telescopic spring 18, so as to fix and clamp rollers of different sizes. The rubber pad 19 can not only reduce vibration, but also avoid direct contact between the roller body 2 and the pressure piece 14 and the connecting seat 6, reducing damage during use. The anti-slip strip 20 increases the friction between the roller and the surface contact object to prevent slipping. The telescopic baffle 21 can be adjusted following the pressure piece 14 and clamped on the clamping piece 22 to limit the movement of the two ends of the roller body 2 and avoid position displacement.

[0036] The specific usage is as follows:

[0037] First, insert the rotating shaft of one end of the drum body 2 between the pressing piece 14 and the connecting seat 6. The pressing piece 14 fixes and clamps the rotating shaft of the drum body 2 through the elastic action of the telescopic spring 18. Then install the other end in the same way. Rotate the telescopic baffle 21 and adjust the length appropriately. Buckle the slot 23 on the clamping piece 22 to prevent the two ends of the drum body 2 from shifting during the rotation process.

[0038] During use, the air pump 12 inflates or deflates the shock-absorbing airbag 5, and adjusts the shock-absorbing effect by changing the hardness of the shock-absorbing airbag 5, which has a better effect during use. If you want to change the support height, pull the fixing rod 8 outward so that the fixing rod 8 extends from the fixing groove 9, then slide the telescopic rod 4 to the appropriate position, and reinsert the fixing rod 8 into the corresponding fixing groove 9 to fix the position of the telescopic rod 4.

[0039] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
