Description

Multiple buffering shock-proof structure of running machine

Technical Field

The utility model relates to a multiple buffering and shock-absorbing structure of a running machine, which is mainly arranged at the positions of side frames and front supports at two sides of the running machine and is used for adjusting the effects of buffering and shock absorption and eliminating noise.

Background

The structure of a conventional treadmill is shown in fig. 1, wherein a support plate 11 is disposed in a frame 10, a running belt 12 is wound around the support plate 11, a sporter performs a running and stepping exercise on the running belt 12, a rubber shock absorbing block 13 is screwed on the inner side of the frame 10 by a bolt 14, and the shock absorbing block 13 supports the support plate 11 upward to buffer the impact of the sporter during running and stepping, thereby achieving the effects of buffering, shock absorbing and comfort. However, the above-described structure has the following disadvantages: the shock absorbing block 13 is a solid straight cylinder, so the elasticity is poor and the elasticity of the shock absorbing block cannot be adjusted according to the weight of the exerciser and the treading force. Secondly, the direction of the supporting plate 11 pressed by the player is not completely vertical downwards, so that the shock-absorbing block 13 in a straight cylinder shape is easy to deflect and randomly twist (the side surface of the shock-absorbing block is twisted in the same direction to be a curved straight cylinder shape) during actual use, and the shock-absorbing block 13 is easy to damage. Third, when the exerciser uses the treadmill, the exerciser steps on the middle of the supporting plate 11, and the shock absorbing blocks 13 are disposed at both sides of the supporting plate 11, so that the exerciser cannot obtain a better buffering and shock absorbing effect, and the middle of the supporting plate 11 is easy to be sunk when the exerciser uses the treadmill for a long time. And (IV) the common supporting plate 11 can not adjust the required buffering and shock-absorbing strength according to different weights of each exerciser. And (V) when the sporter continuously steps on the treadmill, the treadmill continuously vibrates and the bottom end of the treadmill directly rubs against the ground, so that noise of friction and vibration is generated between the treadmill and the ground, and the quiet living environment of other people or neighbors (particularly between floors of an apartment house) is influenced.

holes

201, 231 and 202 are jointly penetrated and pivoted by a pivoting member 24, and then the two ends of the elastic tube strip 20 are pivoted on the side frame 2;

more than one foot seats 30, as shown in fig. 1, 2, 16 to 20, are respectively disposed at the bottom ends of the two front brackets 3, and include a shaft 31, a cover 32 and a soft cushion block 33, the cover 32 is flexible and disposed on the shaft 31, and a concave open slot 321 is formed towards the ground, the soft cushion block 33 is connected to the lower end of the shaft 31 and is located in the open slot 321 of the cover 32;

the two movable wheels 40 are made of a flexible material as shown in fig. 21, and the rear ends of the two side frames 2 are respectively provided with a fixed seat 4, and the fixed seats 4 are respectively pivoted with the movable wheels 40.

As shown in fig. 16 to 20, the outer periphery of the shaft 31 is provided with an external thread portion 311, the lower end of the shaft is provided with a flange portion 312, the cover 32 is in the form of a suction cup, the top end of the inner side of the cover is provided with an accommodating groove 322, the accommodating groove 322 is used for fixing and accommodating the flange portion 312 of the shaft 31, and the soft cushion block 33 is in a cylindrical shape and is made of a foam material.

As shown in fig. 10 to 15, the front and rear ends of the side frame 2 are provided with shock absorbing blocks 50, the shock absorbing blocks 50 are hollow housings and support the support plate 10, the cross-sectional thickness and the outer circumferential width of the side walls 501 of the shock absorbing blocks 50 are respectively formed from thin to thick and from narrow to wide from top to bottom, the outer circumferential edge of the bottom end of the shock absorbing block 50 extends outward or inward to form a side wing 51, the side wing 51 is provided with a through hole 52, and the through hole 52 is matched with a bolt 53 to lock the shock absorbing block 50 on the side frame 2.

With the above structure and composition design, the use of the present invention is described as follows:

as shown in fig. 3 to 9, when the weight of the sporter is light, the supporting plate 10 does not need to provide a large shock absorbing force, and the pulling ring 22 on the elastic tube strip 20 is pulled by a hand to pull the elastic tube strip 20 to the outside or inside of the side frame 2, so that the elastic tube strip 20 is partially exposed to the outside or inside of the side frame 20, thereby reducing the contact area for supporting the supporting plate 20; on the contrary, when the weight of the sporter is heavy, the supporting plate 10 needs to provide a large shock absorbing force and pull the pulling ring 22 on the elastic tube 20, so that the elastic tube 20 is fully placed on the side frame 2 and fully supports the supporting plate 10.

Secondly, as shown in fig. 16 to 20, when the exerciser steps on the treadmill 1, the soft pad 33 of the foot base 30 prevents the front frame 3 of the treadmill 1 from directly rubbing the ground, and the soft pad 33 is pressed down by the weight and makes the cover 32 absorb the ground.

Third, as shown in fig. 10 to 15, when the supporting plate 10 presses down the shock-absorbing block 50, the side walls of the shock-absorbing block 50 can be uniformly and elastically expanded outward. Therefore, when the supporting plate 10 is pressed down by a smaller amount, only the top surface and the upper thinner sidewall of the shock absorbing block 50 are pressed down (only a smaller cushioning effect is needed; as shown in FIG. 14); when the pressing force of the supporting plate 10 is larger, it will press even the lower thicker sidewall (requiring larger cushioning effect; as shown in fig. 15).

With the structure of the above embodiment, the following benefits can be obtained:

as shown in fig. 2, 3, 5 and 6 in combination with fig. 10 to 12, a foam layer 11 is laid between the support plate 10 and the leather layer 12 of the PVC skin, so that the foam layer 11 of the support plate 10 provides a cushioning effect when a player performs a stepping or running exercise on the running belt 5 of the treadmill 1. In addition, a leather layer 12 of PVC leather is laid on the support plate 10, and the leather layer 12 and the running belt 5 repeatedly wound are rubbed with each other, and the better wear resistance of the PVC leather material is utilized to simultaneously prolong the service life of the support plate 10 and the running belt 5.

Secondly, as shown in fig. 2 to 9, the exerciser can pull the pulling ring 22 on the elastic tube strip 20 according to his/her own weight to increase or decrease the contact area between the elastic tube strip 20 and the supporting plate 10, so as to change the shock absorbing force of the supporting plate 10 to different degrees. In addition, the fixing sleeve 23 is sleeved at two ends of the elastic tube strip 20 and is pivoted together with the side frame 2, so that the fixing sleeve 23 strengthens the pivoting structure at two ends of the elastic tube strip 20, thereby prolonging the service life and avoiding the damage and fracture of two ends of the elastic tube strip 20 caused by the long-time repeated pulling of the elastic tube strip 20.

Third, as shown in fig. 16 to 20, the cushion blocks 33 and the cover 32 of the foot base 30 prevent the front frame 3 of the treadmill 1 from directly rubbing the ground, the cushion blocks 33 are pressed down by the weight, and the cover 32 absorbs the ground, so that the treadmill 1 does not move freely on the ground besides the effect of sound absorption and shock absorption provided by the cushion blocks 33; furthermore, as shown in fig. 21, the moving wheels 40 made of soft material at the rear ends of the two side frames 2 are used to obtain better sound absorption and shock absorption effects.

As shown in fig. 10 to 16, the sectional thickness and the outer circumferential width of the sidewall 501 of the shock absorbing block 50 are gradually increased from thin to thick and gradually decreased from narrow to wide from top to bottom, respectively, and the shock absorbing block 50 can provide different degrees of cushioning and shock absorbing force according to the force of each exerciser's weight pressing down the supporting plate 10. Moreover, the shock absorbing block 50 can be uniformly stressed when being pressed down by the supporting plate 10, and can not deflect and randomly twist, so that the shock absorbing block is not easy to damage and can be used for a long time.
