[0027] Embodiment 1

[0028] Combined with the attached Figures 1 to 3 、 Figure 5 As shown in the figure, an installation structure of a rear roller of a treadmill includes a roller body 1 and a support frame 2. The roller body 1 is connected and arranged on the support frame 2. Mounting seats 3 are respectively rotatably arranged at both ends of the rotating shaft of the roller body 1. Buffer support components are symmetrically arranged on the support frame 2. The buffer support components include a tube body 4 fixedly arranged on the support frame 2. A support rod 5 is slidably inserted into the tube body 4. One end of the support rod 5 is fixedly provided with a support plate 6. A first shock-absorbing spring 7 is sleeved outside the tube body 4. Both ends of the first shock-absorbing spring 7 are respectively connected with the support frame 2 and the support plate 6. A slot 18 is arranged on the mounting seat 3. The mounting seat 3 is fixedly connected with the support frame 2 through an insertion rod 19. A fixing component matched with the insertion rod 19 is arranged in the mounting seat 3.

[0029] Through the above structure, when the roller body 1 is stressed, under the action of the buffer support component, the stress on the mounting seat 3 on the roller body 1 is reduced, thereby reducing the deformation degree and prolonging the service life. The mounting seat 3 is connected with the support frame 2 through the insertion rod 19, and the installation efficiency is high, and it is convenient for disassembly and assembly.

[0030] Combined with the attached Figures 3 to 5As shown, one end of the support rod 5 located inside the pipe body 4 is provided with a limit plate 12. A second shock-absorbing spring 13 is connected to the limit plate 12. The second shock-absorbing spring 13 is sleeved on the support rod 5. A rubber pad 14 is provided on the surface of the support plate 6 in contact with the mounting seat 3. A jack 15 with the same diameter as the insertion rod 19 is provided on the support frame 2. A card slot 16 is provided on one side of the jack 15. The insertion rod 19 passes through the jack 15 and is inserted into the slot 18.

[0031] With the above structure, the second shock-absorbing spring 13 and the first shock-absorbing spring 7 cooperate with each other to offset the force, playing a role in shock absorption and buffering. Rubber has a buffering and shock-absorbing effect according to its own material properties, and at the same time reduces the wear between the mounting seat 3 and the support plate 6. The setting of the card slot 16 reduces the probability of accidentally touching and removing the insertion rod 19 on the premise of facilitating the removal of the insertion rod 19.

[0032] Embodiment 2

[0033] On the basis of Embodiment 1, as shown in the attached Figure 5 and Figure 6 As shown, the fixing component includes a fixing rod 8. Grooves 9 are respectively provided on both sides of the slot 18. The fixing rod 8 is connected and arranged in the groove 9 through a telescopic spring 10. A fixing hole 11 matching the fixing rod 8 is provided on the insertion rod 19. The edge of the fixing hole 11 is rounded. A through hole 17 for fitting the mounting seat 3 is provided on the upper surface of the support frame 2.

[0034] With the above structure, the fixing rod 8 is inserted into the fixing hole 11 to fix the mounting seat 3 and prevent it from rotating with the roller body 1. The setting of the through hole 17 facilitates the installation of the roller body 1 on the support frame 2.

[0035] The specific usage method is as follows:

[0036] Install the mounting seats 3 at both ends of the roller body 1 into the support frame 2 through the through hole 17, and then snap the mounting seat 3 between the two support plates 6. Since the support plate 6 is connected to the support frame 2 through the first shock-absorbing spring 7, the support plate 6 can adapt to mounting seats 3 of different sizes and be adjusted according to the diameter of the mounting seat 3, so that the support plate 6 is closely attached to the mounting seat 3 to fixedly clamp the mounting seat 3. Then insert the insertion rod 19 from the jack 15 into the slot 18, and rotate the insertion rod 19 so that the fixing rod 8 in the slot 18 is inserted into the fixing hole 11 to fix the mounting seat 3. The rubber pad 14 can not only increase the friction force but also has a buffering and shock-absorbing effect;

[0037] During use, the first shock-absorbing spring 7 and the second shock-absorbing spring 13 cooperate with each other according to their own elastic characteristics to offset and slow down the force applied to them, reducing the degree of damage to the mounting seat 3.

[0038] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. In summary, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
