The body-building device can only rotate in one direction, so that a user can be prevented from being injured in the using process.
Description
Technical Field
The utility model relates to the field of fitness devices, in particular to a one-way movement fitness device.
Background
The abdominal muscle wheel is an apparatus for exercising body with simple structure, convenient application and obvious effect. When exercising, the two knees kneel on the ground, the handles are held by the two hands, the abdominal muscle wheels are arranged on the front side of the body, the abdominal muscle wheels can be used for doing abdominal exercise at home, and the effect is much better than that of the traditional sit-up. However, the existing abdominal muscle wheel can roll in two directions, and when a user holds the handle to tilt forwards, the user is easy to move reversely if the user does not move to the right position, so that the waist is injured.
Disclosure of Invention
In order to overcome the defects in the prior art, the utility model aims to provide a one-way movement fitness device.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the unidirectional movement body-building device comprises a hub inner ring, a hub outer ring and a middle shaft, wherein the hub outer ring is rotatably sleeved on the outer side of the hub inner ring, a shaft hole in the center of the hub inner ring is fixedly sleeved in the middle of the middle shaft, and two ends of the middle shaft respectively extend towards two sides of the hub inner ring to form a handheld part; the hub inner ring is characterized in that at least two long slotted holes are formed in the inner side of the hub outer ring along the circumferential direction, the height of each long slotted hole is gradually reduced from one end to the other end, a rolling body is arranged in each long slotted hole, the lower end of each long slotted hole is connected with a spring, the free end of each spring abuts against the corresponding rolling body, and the rolling bodies are in contact with the outer side of the hub inner ring and can only freely rotate in one direction.
Furthermore, ball bearings are respectively embedded at two sides of the outer ring of the hub, the inner ring of each ball bearing is fixedly sleeved on the middle shaft, and the inner ring of each ball bearing is fixed on the outer ring of the hub.
Furthermore, a tire is fixedly sleeved on the outer side of the outer ring of the hub.
Further, the rolling bodies are rollers.
By adopting the technical scheme, the rolling body connected with the spring is arranged in the long slot hole with the height gradually reduced from one end to the other end, and the ingenious structural design ensures that the outer ring of the hub can only rotate in one direction relative to the inner ring of the hub. In addition, can mark single pivoted direction on body-building device, the user can use according to the direction of mark, guarantees that the user is not injured in the use.
Drawings
The utility model is described in further detail below with reference to the accompanying drawings and the detailed description;
FIG. 1 is a schematic view of the present invention;
FIG. 2 is a cross-sectional view of the present invention;
FIG. 3 is a partial view of FIG. 2;
fig. 4 is a schematic view of another embodiment of the present invention.
Detailed Description
As shown in fig. 1-4, the one-way movement fitness device of the present invention comprises a hub inner ring 1, a hub outer ring 2 and a middle shaft 3, wherein the hub outer ring 2 is rotatably sleeved outside the hub inner ring 1, a shaft hole at the center of the hub inner ring 1 is fixedly sleeved in the middle of the middle shaft 3, and two ends of the middle shaft 3 respectively extend to two sides of the hub inner ring 1 to form a handheld portion; the inner side of the hub outer ring 2 is provided with at least two long slotted holes 4 along the circumferential direction, the height of each long slotted hole 4 is gradually reduced from one end to the other end, a rolling body 5 is arranged in each long slotted hole 4, one end of each long slotted hole 4 with the lower height is connected with a spring 6, the free end of each spring 6 abuts against the corresponding rolling body 5, and the rolling bodies 5 are in contact with the outer side of the hub inner ring 1 and can only freely rotate towards one direction.
The outer side of the hub outer ring 2 is fixedly sleeved with a tire, and the tire has a damping and buffering effect.
The rolling bodies 5 are rollers, the rollers are in surface contact with the hub inner ring 1, the friction force is relatively large, and effective locking can be kept during reverse motion.
Preferably, the direction of the single rotation can be marked on the exercise device and the user can use it according to the marked direction. When in exercise, the hands and feet of a person are fixed at the two ends of the middle shaft 3; when a wheel (a hub outer ring 2) rotates forwards, the hub inner ring 1 does not move, and a rolling body 5 in the hub outer ring 2 rotates freely; when the wheel (the hub outer ring 2) rotates in the opposite direction, the rolling body 5 rolls towards the narrow direction of the long slotted hole 4; because the height of the hole at the position is smaller than the diameter of the rolling body 5, the rolling body 5 can be clamped by the inner ring of the hub and cannot rotate, and the wheel cannot rotate; thus, the wheel can only move in one direction (e.g., forward, not backward).
In addition, as another embodiment, as shown in fig. 4, the position of the spring 6 is changed, and the working principle is the same, which is not described in detail.
While the utility model has been described in connection with the above embodiments, it is to be understood that the utility model is not limited to the disclosed embodiments, which are illustrative and not restrictive, and that those skilled in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
