Description

Technical Field

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

[0002] A martial arts stick is a common martial arts training device, also known as a "club". Traditional martial arts sticks are made of tough wood, and their center of gravity cannot be adjusted. When a person holds a martial arts stick to perform training actions such as chopping, stabbing, swinging, and sweeping, the hand holds the tip of the martial arts stick, and the center of gravity of the martial arts stick is generally at the center position. For beginners with less strength, since the center of gravity of the martial arts stick is relatively forward, if the wrist strength is small, it is not easy to wave the martial arts stick, and they may become out of breath after waving it a few times, which is not conducive to beginners mastering the martial arts stick training actions. Content of the Utility Model

[0003] Therefore, in view of the above problems, the utility model provides a martial arts stick with adjustable center of gravity, which can adjust the center of gravity of the martial arts stick and is simple and convenient to operate.

[0004] To achieve the above object, the utility model adopts the following technical solutions:

[0005] A martial arts stick with adjustable center of gravity includes a stick body, and a cavity penetrating the stick body is provided along the length direction of the stick body;

[0006] It also includes a first disc hanging weight, a first rope, a counterweight, a spring buckle, a second disc hanging weight, and a second rope;

[0007] The counterweight is slidably arranged in the cavity;

[0008] The first disc hanging weight is detachably buckled at the first opening end of the cavity, and the first rope passes through the first disc hanging weight and is connected to the first end of the counterweight;

[0009] The second disc hanging weight is detachably buckled at the second opening end of the cavity, and the second rope passes through the second disc hanging weight and is connected to the second end of the counterweight through a spring buckle.

[0010] Further, a shock-absorbing material layer is sleeved on the outer surface of the stick body.

[0011] Further, an anti-slip cushion layer is sleeved on the outer surface of the shock-absorbing material layer.

[0012] Further, a magnet that slides synchronously with the counterweight is also arranged on the counterweight.

[0013] By adopting the foregoing technical solutions, the beneficial effects of the utility model are:

[0014] This adjustable center-of-gravity martial arts stick is provided with a slidable counterweight block inside the cavity. After the user adjusts the position of the counterweight block, the first rope and the second rope can be tightened and fixed respectively through the first disc hanger and the second disc hanger, so as to fix the position of the counterweight block. When the center of gravity needs to be adjusted, since the spring buckle can be elastically stretched, the first disc hanger and the second disc hanger can be pulled out from the stick body respectively by force (at this time, the spring buckle stretches and the lengths of the first rope and the second rope remain unchanged), and it can be controlled that the first disc hanger releases the first rope and the second disc hanger releases the second rope, so as to adjust the position of the counterweight block, change the center of gravity of the stick body, and after the adjustment is completed, the first rope and the second rope are tightened again and fixed respectively through the first disc hanger and the second disc hanger.

[0015] Furthermore, a shock-absorbing material layer is sleeved on the outer surface of the stick body to reduce the vibration of the stick body during use, and an anti-slip cushion layer is sleeved on the outer surface of the shock-absorbing material layer to increase friction and play an anti-slip role.

[0016] Furthermore, a magnet that slides synchronously with the counterweight block is also arranged on the counterweight block, so that the position of the counterweight block can be detected through ferromagnetic materials, which is convenient for adjusting the position of the counterweight block.

[0019] Figure 3 is a cross-sectional view of the stick body in Embodiment 2. Detailed Embodiments

[0020] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0021] Embodiment 1

[0022] Refer to Figure 1 and Figure 2 , this embodiment provides an adjustable center-of-gravity martial arts stick, which includes a stick body 1, and a cavity 10 penetrating the stick body 1 is opened along the length direction of the stick body 1.

[0023] It also includes a first disc sling 2, a second disc sling 3, a counterweight 4, a first rope 5, a second rope 6, and a spring buckle 7. In this specific embodiment, preferably, both the first rope 5 and the second rope 6 are made of steel wire ropes, and the steel wire rope structure is reliable. When actually implemented, the first rope 5 and the second rope 6 can also be made of nylon ropes, hemp ropes, etc. Preferably, both the first disc sling 2 and the second disc sling 3 are made of steel wire rope disc slings. After the steel wire rope passes through the steel wire rope disc sling, it will be locked; the locked steel wire rope can also be released as needed, adjusted, and then locked again. The steel wire rope disc sling is an existing device in the art and will not be elaborated in detail here.

[0024] The counterweight 4 is slidably arranged in the cavity 10. By adjusting the position of the counterweight 4 in the cavity 10, the center of gravity of the martial arts stick can be adjusted. And a magnet that slides synchronously with the counterweight 4 is also arranged on the counterweight 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 4). When in use, the position of the magnet can be sensed by a ferromagnetic material outside, and then the position of the counterweight 4 can be inferred, which is convenient for adjusting the position of the counterweight 4.

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

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

[0027] In this adjustable center-of-gravity martial arts stick, by arranging a slidable counterweight 4 in the cavity 10, after the user adjusts the position of the counterweight 4, the first rope 5 and the second rope 6 can be tightened and fixed respectively through the first disc sling 2 and the second disc sling 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 stick body 1 is waved, the counterweight 4 will slide with a very small amplitude, which will not affect the use. The parts of the first rope 5 and the second rope 6 that protrude from the stick body 1 can be wound around the stick body 1, or cut, or covers for respectively accommodating the first rope 5 and the second rope 6 can be arranged at both ends of the stick body 1.

[0028] When it is necessary to adjust the center of gravity, since the spring buckle 7 can be elastically stretched, the first disc hanging weight 2 and the second disc hanging weight 3 can be pulled out from the rod body 1 by force. At this time, the spring buckle 7 elongates, and the lengths of the first rope 5 and the second rope 6 remain unchanged. It is possible to control the first disc hanging weight 2 to release the first rope 5 and the second disc hanging weight 3 to release the second rope 6, so as to adjust the position of the counterweight 4, change the center of gravity of the rod body 1. After the adjustment is completed, the first rope 5 and the second rope 6 are tightened again and fixed through the first disc hanging weight 2 and the second disc hanging weight 3 respectively.

[0029] Embodiment 2

[0030] Based on the above Embodiment 1, the improvement of this specific embodiment also lies in:

[0031] A shock-absorbing material layer 11 is sleeved on the outer surface of the rod body 1, and an anti-slip cushion layer 12 is sleeved on the outer surface of the shock-absorbing material layer 11. The shock-absorbing material layer 11 is made of materials with shock-absorbing functions such as rubber, silicone, or PVC foam, etc., to reduce the vibration of the rod body 1 during use. The anti-slip cushion layer 12 is made of materials with sweat-absorbing and anti-slip effects such as chemical fiber canvas or PU material, etc., to increase friction and play an anti-slip role.
