Technical Field

[0001] The utility model relates to the technical field of sports equipment, in particular to a martial arts roller with adjustable center of gravity. Background Art

[0002] The martial arts stick is a common martial arts training device, also known as a "stick". The traditional martial arts stick is made of tough wood, and its center of gravity cannot be adjusted. When a person holds a martial arts stick to perform training movements such as splitting, poking, swinging, and sweeping, the stick's center of gravity is generally in the center. For beginners with less strength, since the center of gravity of the martial arts stick is relatively forward, if the wrist strength is weak, it is difficult to swing the martial arts stick, and the person may be exhausted after swinging it a few times, which is not conducive to beginners mastering the martial arts stick training movements.

[0020] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0021] Embodiment 1

[0022] refer to Figure 1 and Figure 2 The present embodiment provides a martial arts stick with an adjustable center of gravity, comprising a roller body 1, and a cavity 10 penetrating the roller body 1 is provided along the length direction of the roller body 1.

[0023] It also includes a first disc hanging weight 2, a second disc hanging weight 3, a counterweight 4, a first rope 5, a second rope 6, and a spring buckle 7. In this specific embodiment, preferably, the first rope 5 and the second rope 6 are both made of steel wire ropes, and the steel wire rope structure is reliable. In actual implementation, the first rope 5 and the second rope 6 can also be made of nylon rope, hemp rope, etc. Preferably, the first disc hanging weight 2 and the second disc hanging weight 3 are both made of wire rope disc hanging weights, and the wire rope will be locked after passing through the wire rope disc hanging weight; the locked wire rope can also be released as needed, and the wire rope can be locked again after adjustment. The wire rope disc hanging weight is an existing device in the field and will not be described in detail here.

[0024] The counterweight block 4 is slidably arranged in the cavity 10, and the center of gravity of the martial arts stick can be adjusted by adjusting the position of the counterweight block 4 in the cavity 10. In addition, a magnet is arranged on the counterweight block 4 (not shown in the figure, it should be noted that the installation position of the magnet should not affect the movement of the counterweight block 4). When in use, the position of the magnet can be sensed by an external ferromagnetic material to infer the position of the counterweight block 4, so as to facilitate the adjustment of the position of the counterweight block 4.

[0025] The first disc hanging weight 2 is detachably buckled on a first opening end (not marked in the figure) of the cavity 10 , and the first rope 5 passes through the first disc hanging weight 2 and is connected to a first end of the counterweight 4 .

[0026] The second disc hanging weight 3 is detachably buckled on the second opening end (not marked in the figure) of the cavity 10 , and the second rope 6 passes through the second disc hanging weight 3 and is connected to the second end of the counterweight 4 through the spring buckle 7 .

[0027] The adjustable center of gravity martial arts stick is provided with a slidable counterweight 4 in the cavity 10. After adjusting the position of the counterweight 4, the user can tighten the first rope 5 and the second rope 6 and fix them respectively through the first disc hanging code 2 and the second disc hanging code 3. At this time, the spring buckle 7 is in a stretched state, and the first rope 5 and the second rope 6 are taut, thereby fixing the position of the counterweight 4. At this time, when the roller body 1 is swung, the counterweight 4 will slide very slightly and will not affect the use. The part of the first rope 5 and the second rope 6 exposed from the roller body 1 can be wound on the roller body 1, or cut, or covers for respectively accommodating the first rope 5 and the second rope 6 are provided at both ends of the roller body 1.

[0028] When the center of gravity needs to be adjusted, since the spring buckle 7 can be elastically pulled up, the first disc hanging weight 2 and the second disc hanging weight 3 can be pulled out from the roller body 1 respectively. At this time, the spring buckle 7 is extended, and the length of the first rope 5 and the second rope 6 remains unchanged. The first disc hanging weight 2 can be controlled to release the first rope 5 and the second disc hanging weight 3 can be controlled to release the second rope 6, thereby adjusting the position of the counterweight 4 and changing the center of gravity of the roller body 1. After the adjustment is complete, the first rope 5 and the second rope 6 are re-tightened and fixed by the first disc hanging weight 2 and the second disc hanging weight 3 respectively.
