Description

Technical Field

[0001] The utility model relates to the technical field of training equipment, in particular to an arm strength ball. Background Art

[0002] The arm strength ball is an extension of the wrist strength ball technology. The earliest wrist strength ball was invented by people from Taiwan, China. It adopts the principle of gyroscopic precession. By rotating the user's wrist, the gyroscope in the wrist strength ball continues to accelerate and generate huge centrifugal force. The rotation speed and acceleration rhythm of the wrist strength ball can be adjusted by human control (the current maximum rotation speed that users can achieve has exceeded 20,000 revolutions per minute), thereby achieving the purpose of training hand muscles, arm muscles and wrist flexibility. By adding electromagnetic induction LED lights to the wrist strength ball, the wrist strength ball emits light of different colors as the rotation speed changes, which adds to the fun of use. Since its launch on the market, the wrist strength ball has quickly swept the European and American markets and has been gradually promoted to the global market.

[0003] The earliest wrist strength ball patent that is currently publicly available in China is the utility model patent with application number CN99226158.9, which was applied for by Lin Jiande of Taiwan on April 2, 1999 and authorized on March 22, 2000. The structural design of this patent is still in use today. Its only pain point is that the top of the gyro ball in the wrist strength ball is exposed outside the outer shell of the wrist strength ball, so that when the gyro ball rotates at high speed, the user may be careless and cause the skin to be scratched by the high-speed rotating gyro ball. At the same time, the skin may be further sent into the gap between the gyro ball and the outer shell of the wrist strength ball under the action of friction, causing pinching. In this regard, the application number is CN02253. Patent No. 289.7 proposes an activation structure for a wrist strength trainer, which adopts a fully enclosed wrist strength ball structure and uses an external rack with a pull ring as an activation device. Although the safety problem of use is solved, the activation device and the wrist strength ball are not integrated, which is inconvenient to carry; therefore, the patent with announcement number CN203001833U proposes a hand-pull-activated wrist strength fitness ball. Taking this patent as an example, a type of wrist strength ball activated by a built-in pull rope is launched on the market. The activation device and the fully enclosed wrist strength ball itself are integrated, which is safe and convenient to carry and use. The wrist strength ball technology has developed to this point, and the technology itself is relatively mature and complete.

[0004] On the basis of the above, people have made some expansions and improvements based on the existing mature wrist strength ball technology, that is, on the basis of the wrist strength ball, an external handheld structure is added, just like putting a mobile phone case on a mobile phone. Specifically, the appearance patent with announcement number CN305554033S proposes a wrist strength ball product with finger sleeves on the outside. The user can put his fingers into the finger sleeves while holding the wrist strength ball, thereby preventing the wrist strength ball from slipping out of the hand during high-speed operation; the appearance patent with announcement number CN305957992S provides a handle for the wrist strength ball set, and the user can drive the wrist strength ball by holding the handle, adding a new wrist strength ball fitness mode. However, the wrist strength ball has a single handle, and the training mode and effect are relatively limited.

[0005] In summary, the development of wrist strength ball technology so far has been centered around the improvement of the wrist strength ball itself. In essence, the ball is held in one hand and "dribbled" with one hand. What is trained is one arm, the training mode is single, and it is difficult for single-arm training to fully and effectively drive the training of the chest and waist and back muscles. In this regard, there is currently a lack of a large wrist strength ball on the market that can enlarge the small wrist strength ball that can be held in one hand, requires both hands to "dribble the ball", and can simultaneously drive the training of the upper body muscle groups.

[0055] Establish space with the axis of transmission shaft 1 and the axis of bidirectional bearing 13 as coordinate axes o - xyz The rectangular coordinate system can be obtained o - xy ,o - xz , o - yz In the above five embodiments, the three pairs of handles 23 are located in different directions of the three coordinate planes, and the three pairs of handle rings 26 are located in different directions of the three coordinate planes.

[0056] In the present invention, the lifting ring 26 on the handle 23 and the lifting ring 26 on the outer surface of the spherical housing assembly may have different shapes, but are collectively referred to as lifting rings 26 and are both used for hanging the rope buckle 25 .

[0057] In the above five embodiments, the outer diameter of the spherical housing assembly is 15 cm; after the handle 23 is installed, Fig.14 Taking Example 2 as an example, the diameter of the circumscribed enveloping sphere of the entire device is 28.5 cm, and the cross-section of the handle 23 is a circle with a diameter of 2.5 cm; the total length of the holding rope 24 plus the locking buckle 43 and the rope buckle 25 is 24 cm; the wire diameter of the pull rope 10 is between 2 mm and 2.5 mm; the one-way bearing 9 adopts a one-way needle bearing, model HF0812.

[0058] The working principle of this utility model: Figure 1 Taking the embodiment 1 shown as an example, when the device is in use, one hand grasps the device, and the other hand manually pulls the pull cap 12 to pull the pull cap 12 out of the holder 36, and quickly pulls the pull cap 12 until it cannot be pulled, and then manually releases the pull cap 12. In this process, the pull rope 10 wound on the pulley 7 is quickly pulled out, thereby driving the pulley 7 to rotate. Using the right-hand rule, Figure 1 In the middle, hold the transmission shaft 1 with your right hand, with four fingers pointing in the direction of rotation of the pulley 7, and the thumb will point to Figure 1 The right side direction is also the direction in which the transmission shaft 1 can rotate in the one-way bearing 9. Assume that this direction is the positive direction and the reverse direction is the negative direction. When the pulley 7 accelerates in the positive direction, it will drive the one-way bearing 9 to accelerate in the positive direction through the bearing seat 8. Since the transmission shaft 1 is stationary in the initial state, the one-way bearing 9 rotates in the positive direction relative to the transmission shaft 1, which is equivalent to the transmission shaft 1 rotating in the negative direction relative to the one-way bearing 9, and the transmission shaft 1 can only rotate in the positive direction relative to the one-way bearing 9. Therefore, in the above process, the one-way bearing 9 and the transmission shaft 1 are a rigid whole, and the one-way bearing 9 will drive the transmission shaft 1 to accelerate in the positive direction.

[0059] In the above process, the pulley 7 drives the mainspring 6 to store force through the outer slot 42. When the pull rope 10 is pulled to a point where it can no longer be pulled and the pull cap 12 is manually released, the pulley 7 automatically rotates in the negative direction under the restoring force of the mainspring 6 to retract the pull rope 10, and finally the pull cap 12 is re-engaged in the holder 36. In this process, the one-way bearing 9 rotates in the negative direction relative to the transmission shaft 1, that is, the transmission shaft 1 rotating at a high speed in the positive direction still rotates in the positive direction relative to the one-way bearing 9 rotating in the negative direction, and the movement can continue. At this time, hold the spherical housing assembly with both hands, and drive the entire device to swing in a conical surface based on the axis of the two-way bearing 13. During the swinging of the conical surface, the track 4 surfaces of the two tracks 4 continue to tilt, so that the two ends of the transmission shaft 1 are each in close contact with the track 4 surface of the only track 4, so as to Figure 1 For example, when the device is tilted to the left, the left end of the transmission shaft 1 is in close contact with the lower track 4, and the right end of the transmission shaft 1 is in close contact with the upper track 4; when the device is tilted to the right, the left end of the transmission shaft 1 is in close contact with the upper track 4, and the right end of the transmission shaft 1 is in close contact with the lower track 4; based on the external interference conditions of the above-mentioned conical surface swing, under the action of friction, the transmission shaft 1 will roll between the two tracks 4, that is, drive the gyroscope 2 to rotate around the axis of the two-way bearing 13, and control the rhythm of the above-mentioned conical surface swing with both hands, which can continuously accelerate the rotation of the gyroscope 2 relative to the axis of the transmission shaft 1 through friction; at the same time, on the one hand, the two-way bearing 13 The design of the bearing 13 allows the pull rope 10 to rotate synchronously around the axis of the two-way bearing 13 relative to the gyroscope 2, thereby avoiding entanglement and jamming of the mechanism movement; on the other hand, when the gyroscope 2 rotates at a high speed, it drives the two induction coils 28 on the circuit board 29 to rotate at a high speed relative to the magnet 30 on the cover plate 11, cutting the magnetic flux lines to generate current, causing the LED lamp 27 to emit light; the faster the speed of the gyroscope 2, the greater the current generated. The circuit board 29 is designed according to the current classification, so that at different speed levels, the LED lamp 27 can emit light of a specific color corresponding to the speed level.

[0060] Providing the counterweight hole 33 or the counterweight block 34 on the gyroscope 2 is not only conducive to starting, but also can significantly enhance the centrifugal force when the gyroscope 2 rotates at a high speed, thereby achieving the purpose of muscle training.

[0061] The design of the upper limit ear 39 on the retaining frame 3 and the upper limit column 40 on the box body 5 is to prevent the box body 5 from deflecting left and right around the axis of the transmission shaft 1 relative to the retaining frame 3. The specific working principle is that the box body 5 is rotatably mounted on the transmission shaft 1, and the transmission shaft 1 is rotatably mounted on the retaining frame 3. In this case, when the two limit columns 40 located on both sides of the transmission shaft 1 are respectively overlapped on the two limit ears 39 located on both sides of the transmission shaft 1, the freedom of the mechanism is locked, and the box body 5 cannot deflect left and right around the axis of the transmission shaft 1 relative to the retaining frame 3; this function can also be achieved by directly setting a rigid connection structure on the box body 5 and the retaining frame 3, but compared with the current design of the limit ears 39 and the limit columns 40, the manufacturing cost is higher.

[0062] The box body 5 cannot rotate around the axis of the transmission shaft 1 relative to the retaining frame 3, thus ensuring the normal operation of the aforementioned movement started by the pull rope 10.

[0063] Based on the above principle, when the device is started, the focus is on how the user plays with both hands, that is, how to achieve the aforementioned conical surface swinging motion with both hands.

[0064] Taking Example 1 as an example, after starting, the palms of both hands can hold the spherical housing assembly along the axis direction of the bidirectional bearing 13, that is, Figure 1 The upper and lower sides are shown, and then the spherical shell assembly is quickly rubbed between the two palms. By controlling the rhythm, the gyroscope 2 is accelerated quickly. After the gyroscope 2 runs at a high speed, the holding position can be switched, that is, it can be held with both hands. Figure 1 The left and right sides shown in the figure, and then both hands drive the device to do conical swinging motion. At this posture, the arms will drive the upper body to swing slightly.

[0065] Taking Example 2 as an example, after starting, the gyroscope 2 can be accelerated by holding any pair of the three pairs of handles 23 with both hands.

[0066] Taking Example 3 as an example, it is suitable for advanced players. After starting the device, both hands first accelerate the gyroscope 2 by holding the spherical shell assembly. After the gyroscope 2 runs at high speed, both hands pull a holding rope 24, and the holding rope 24 needs to be straightened. Only when the holding rope 24 is straightened can the conical surface swinging motion be further realized. In this scenario, not only does the player need to provide the force required for the conical surface swinging motion, but the player also needs to continuously provide force to both sides to maintain the holding rope 24 in a straight state. The training effect is more in-depth and more difficult, which is suitable for professional players who play this device or practice martial arts all year round.

[0067] Example 4 combines the gameplay of Example 2 and Example 3.

[0068] In Example 5, based on the playing method of Example 4, a ring 26 is added to the handle 23, thereby obtaining a new playing method, that is, one hand holds the handle 23 and the other hand holds the pulling rope 24, and the two pulling ropes 24 are connected in series, and the distance between the two hands in this scene can also be adjusted.

[0069] In actual product applications, the handle 23, the hanging ring 26, and the holding rope 24 can all be configured as a detachable set shipped together with the main body, so that the user can choose the assembly and use mode according to the user's preference.

[0070] The above-mentioned usage principle only describes some usage methods of the five embodiments of the utility model. The device usage methods of the remaining implementation modes not listed in this article are within the protection scope of this patent. All methods can be summarized as one or more combinations of the holding technique of the two-hand holding unit, the holding technique of the two-hand holding unit, and the pulling technique of the two-hand pulling unit.
