Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to an anti-skid roller mechanism of a fitness equipment. Background Art

[0002] Current fitness equipment such as spinning bikes, rowing machines or elliptical machines are usually provided with rollers on the ground at the front and rear sides in order to facilitate their movement in the room, and support feet are provided on the ground at the other side. When it is necessary to move the fitness equipment, one side of the support feet is lifted up, and only the rollers are on the ground, so that the fitness equipment can be pushed to move, thereby making the movement of the fitness equipment more convenient.

[0003] However, after adopting the above design, during use, since the rollers are placed on the ground and roll, the fitness machine is limited in displacement only by the friction between the support feet on one side and the ground. Compared with the solution of providing support feet on both the front and rear sides, the stability is poor and it is easy to slip.

[0004] Therefore, the problem of how to increase the friction between the position where the rollers of the fitness equipment are set and the ground during use of the fitness equipment needs to be solved. Utility Model Content

The axle rod extends left and right, spanning the roller groove. Both ends pass through the axle rod sliding groove on the corresponding side and enter the spring groove on the corresponding side. An elastic member is inserted into each spring groove. The elastic member elastically pushes the axle rod downward to elastically support between the roller and the mounting frame.

[0014] Furthermore, the bottom of the mounting frame has a transverse tube, the bottom side of the transverse tube is provided with a wheel frame mounting opening, the wheel frame is mounted on the wheel frame mounting opening, and the roller groove, spring groove and shaft rod slide groove are all formed on the wheel frame.

[0015] Furthermore, the wheel frame is detachably mounted on the wheel frame mounting opening.

[0016] Furthermore, the wheel frame has a limit plate on the bottom side, and the opposite side edges of the wheel frame each elastically protrude with an elastic hook. When the wheel frame is installed on the wheel frame mounting port, the top surface of the limit plate abuts against the lower edge of the wheel frame mounting port, and the elastic hook is hooked on the upper edge of the wheel frame mounting port, with the bottom end exposed downward from the limit plate, so that the wheel frame can be detachably mounted on the wheel frame mounting port.

[0017] Furthermore, a plugging head is sleeved on the end of the transverse tube, and the portion of the bottom side of the plugging head protruding from the transverse tube forms the grounding portion.

[0018] Furthermore, the transverse tube extends left and right, the wheel frame is installed in the middle of the transverse tube, and a sealing head is respectively provided at the left and right ends of the transverse tube.

[0019] Furthermore, anti-slip ribs are provided on the outer periphery of the plugging head.

[0020] Furthermore, a wheel frame is detachably mounted on the mounting frame, and the elastic member and the roller are mounted on the wheel frame.

[0021] After adopting the above scheme, the beneficial effects of the utility model are as follows: the mounting frame is fixed on the fitness machine, the roller is movably mounted on the bottom side of the mounting frame, the grounding portion is arranged on the mounting frame and protrudes from the bottom side of the mounting frame, and the elastic member is elastically supported between the roller and the mounting frame, so that after the roller falls on the ground, the mounting frame together with the grounding portion can be supported upward off the ground, so that the fitness machine can be pushed to move with the help of the roller, making the movement of the fitness machine more convenient. When the user stands or sits on the fitness machine to use the fitness machine, the mounting frame is pressed down by the weight of the user, and the elastic member is compressed, so that the mounting frame together with the grounding portion moves downward relative to the roller, and the elastic member is compressed to make the grounding portion fall on the ground, so that the friction force is increased by using the contact between the grounding portion and the ground, thereby achieving the improvement of the friction force between the position where the roller of the fitness machine is set and the ground during the use of the fitness machine.
