Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to a hand exercise device with built-in counterweights. Background Art

[0002] With the progress of society, people's living standards are getting higher and higher. Therefore, people are gradually paying more attention to health problems and starting to exercise. Due to the busy work on weekdays, more people choose to exercise at home. As a result, various exercise equipment has begun to enter thousands of households. Among these exercise equipment, there are those for exercising the whole body, as well as those for exercising local parts such as the arms, waist, back, and legs. Among them, those used to exercise hand strength include, for example, flywheel rods, arm strengtheners, gyroscopic wrist strength balls, etc. However, whether it is a flywheel rod, an arm strengthener, a gyroscopic wrist strength ball, etc., they all have the following problems:

[0003] 1. They are all relatively long. For example, a flywheel rod is about 150 - 160 cm long, and even a smaller arm strengthener is generally about 60 cm long. Even a smaller gyroscopic wrist strength ball, due to the existence of the handle, the overall length also reaches about 50 cm. Therefore, these exercise equipment all take up a lot of space, are not convenient for storage and packing, especially during transportation, and their long shapes are easily squeezed and collided by external objects, resulting in damage.

[0004] 2. Since the overall length of the flywheel rod reaches about 150 - 160 cm, when in use, it will also occupy a large space, otherwise it will easily hit people or objects around. Therefore, there are certain requirements for the usage scenarios.

[0005] 3. Arm strengtheners and gyroscopic wrist strength balls are very unfriendly to beginners without exercise foundation and are relatively difficult to get started. Especially for a gyroscopic wrist strength ball, for beginners, it is basically impossible to start and make it rotate. Even with a starting auxiliary device, after the effect of the auxiliary start ends, it is impossible to make the gyroscopic wrist strength ball continue to rotate, thus unable to achieve the exercise effect. Content of the Utility Model

[0006] In view of the above problems, the utility model overcomes at least one deficiency and provides a hand exercise device with built-in counterweights.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A hand exercise device with built-in counterweights includes a fixing part and a rotating part;

[0009] The fixing part is used to form a path, and the rotating part rotates along the path;

[0010] A hand-held part is provided on the fixing part; a counterweight part is provided inside the rotating part;

[0011] When the counterweight part is swung, the counterweight part generates centrifugal force and drives the rotating part to rotate synchronously along the path.

[0012] In actual use, the user grasps the handle and shakes the rotating part. Because the rotating part contains a counterweight, it also swings. The swinging of the counterweight easily generates centrifugal force, which easily drives the entire rotating part to rotate. Continuous swinging of the counterweight maintains the rotating part's continuous rotation. As the duration of this exercise increases, it strengthens the user's hands.

[0013] Compared with existing exercise equipment, the presence of the counterweight makes the hand exercise device with built-in counterweights much easier to use. Even users with no exercise experience, or users with limited arm strength, such as women and children, can easily rotate the rotating part and maintain its continuous rotation, thereby achieving the effect of exercising the hands.

[0014] In one embodiment of the present invention, a channel is provided inside the fixed portion with two ends communicating with each other. The channel is arc-shaped and provides a path for the rotating portion to rotate. The rotating portion is annular.

[0015] When the rotating part is stationary, the rotating part is partially accommodated in the channel;

[0016] When the rotating part rotates, the rotating part rotates on itself and the parts of the rotating part pass through the channel in sequence.

[0017] In actual use, the arc-shaped channel provides a fixed circular path for the rotating part to rotate. Since the rotating part is not entirely contained within the channel, but only partially, when the rotating part rotates, each part of the rotating part will pass through the channel in sequence, and then continue to rotate repeatedly until the user stops exercising, at which point the rotating part stops rotating.

[0018] Furthermore, the circular rotating part has a diameter of approximately 25-30 cm. Therefore, the overall space occupied is significantly reduced compared to existing exercise equipment. This not only significantly reduces the requirements for the use of a hand exercise device with built-in weights, but also makes it easier and more convenient to pack, store, and transport.

[0019] Moreover, compared with the slender exercise equipment in the prior art, the circular ring structure is more resistant to pressure and collision, making the whole body less likely to be damaged.

[0020] In one embodiment of the present invention, the fixing portion includes a first fixing member and a second fixing member;

[0021] Both the interior of the first fixing member and the interior of the second fixing member are provided with channels that are interconnected at both ends;

[0022] The two channels together form a path.

[0023] By forming a path through the two fixing members together, when the rotating part rotates, it can be more stable and will not have the problem that one side is supported while the other side is not, thus affecting the rotation stability.

[0024] In one embodiment of the present utility model, both channels are arc-shaped channels, the circumferential radii of the two arc-shaped channels are equal, and the two arc-shaped channels together form a circumferential path.

[0025] During actual use, the two arc-shaped channels can allow each part of the rotating part to smoothly pass through the channels when the rotating part rotates, rather than being stuck in the channels.

[0026] In one embodiment of the present utility model, the first fixing member and the second fixing member are connected through a handheld part;

[0027] One end of the handheld part is connected to the first fixing member, and the other end is connected to the second fixing member.

[0028] By connecting the two fixing members through the handheld part, the two fixing members and the handheld part together form a whole. Thus, the track formed by the two fixing members together can be more stable, ensuring that the rotation of the rotating part can be smoother.

[0029] In one embodiment of the present utility model, the rotating part is annular,

[0030] The first fixing member and the second fixing member are respectively sleeved outside the rotating part;

[0031] The handheld part is located in the middle or in the axial direction of the rotating part;

[0032] When the rotating part is stationary, part of the rotating part is received in the channel;

[0033] When the rotating part rotates, the rotating part rotates and each part of the rotating part sequentially passes through the channel.

[0034] During actual use, the two arc-shaped channels provide a fixed circumferential path for the rotation of the rotating part. Since the two fixings are respectively sleeved at two different positions outside the rotating part. Therefore, the rotating part is not entirely received in the channel, only part of it is received in the channel. So when the rotating part rotates, each part of the rotating part will sequentially pass through the two channels and then continuously rotate in a cycle until the user stops exercising, and the rotating part will stop rotating.

[0035] In one embodiment of the present utility model, a receiving cavity is provided on the inner wall of the channel, and a power assist device is provided in the receiving cavity; the power assist device abuts against the outer wall surface of the rotating part.

[0036] The power assist device can help the rotating part pass through the channel more smoothly and avoid the situation where the rotating part gets stuck in the channel.

[0037] In one embodiment of the present utility model, the power assist device includes a fixed shaft, both ends of the fixed shaft are fixed in the receiving cavity, a roller is sleeved outside the fixed shaft, and the roller abuts against the outer wall surface of the rotating part;

[0038] Or,

[0039] The power assist device includes a ball, the ball is accommodated in the receiving cavity, and the ball abuts against the outer wall surface of the rotating part.

[0040] Whether it is the setting of the roller or the setting of the ball, it can reduce the contact area between the outer wall surface of the rotating part and the inner wall surface of the channel, thereby reducing the corresponding frictional resistance, and further enabling the rotating part to smoothly pass through the channel when rotating.

[0041] In one embodiment of the present utility model, a counterweight cavity is provided inside the rotating part, and a counterweight part is accommodated inside the counterweight cavity;

[0042] When the rotating part rotates, the counterweight part moves synchronously with the rotating part.

[0043] Due to the limitation of the counterweight cavity, there will be no relative movement between the counterweight part and the rotating part, and the two can only maintain synchronous movement.

[0044] In one embodiment of the present utility model, the counterweight part is a counterweight block or counterweight liquid or counterweight sand.

[0045] The counterweight liquid is generally water. When a hand exercise device with built-in counterweight needs to be transported or stored, the water can be poured out first, so as to reduce its own weight and make it more convenient for transportation or storage. When a hand exercise device with built-in counterweight is needed, just inject the water again, which is very convenient and simple.

[0046] The beneficial effects of the present utility model are as follows: By setting the counterweight part, a hand exercise device with built-in counterweight can be more easily operated when in use, and the range of its user group can be increased. And its overall size is relatively small, which not only facilitates packing, transportation and storage, but also can reduce the space occupied when in use, and improve its application range. In addition, the circular ring-shaped structure can make the overall structure have the ability to resist compression, impact and damage, and improve its service life.

[0055] The present utility model will be described in detail below with reference to the accompanying drawings.

[0056] Embodiment 1

[0057] As Figures 1 to 3As shown in the figure, a hand exercise device with built-in counterweights includes a fixed part 1 and a rotating part 2; the fixed part 1 is used to form a path, the rotating part 2 is circular, and the rotating part 2 rotates along the path. The circular rotating part 2 has a diameter of approximately 25 - 30 cm. Therefore, the overall occupied space is greatly reduced compared with existing exercise equipment. This not only significantly reduces the requirements for the usage scenarios of a hand exercise device with built-in counterweights, but also makes it simpler and more convenient for packing, storage, and transportation.

[0058] Moreover, the circular structure is more resistant to compression and collision compared with the slender exercise equipment in the prior art, making the whole less likely to be damaged.

[0059] The fixed part 1 includes a first fixing member 11 and a second fixing member 12. Both the inside of the first fixing member 11 and the inside of the second fixing member 12 are provided with channels 5 that communicate at both ends. Both channels 5 are arc-shaped channels 5, the circumferential radii of the two arc-shaped channels 5 are equal, and the two arc-shaped channels 5 together form a circumferential path.

[0060] By forming the path jointly by the two fixing members, the rotating part 2 can rotate more stably during self-rotation, and there will be no problem that one side is supported while the other side is not, thus affecting the stability of self-rotation.

[0061] During actual use, the two arc-shaped channels 5 can enable all parts of the rotating part 2 to smoothly pass through the channels 5 during self-rotation without being stuck in the channels 5.

[0062] In addition, a handheld part 3 is provided on the fixed part 1.

[0063] The first fixing member 11 and the second fixing member 12 are connected by the handheld part 3. One end of the handheld part 3 is connected to the first fixing member 11, and the other end is connected to the second fixing member 12.

[0064] By connecting the two fixing members through the handheld part 3, the two fixing members and the handheld part 3 form a whole together. Thus, the orbit jointly formed by the two fixing members can be more stable, ensuring that the self-rotation of the rotating part 2 can be smoother.

[0065] The two fixing members do not have to be arranged at both ends of the handheld part 3. It is possible that neither of the two fixing members is at the end of the handheld part 3. For example, extend the handheld part 3, and both ends of the handheld part 3 respectively bypass the two fixing members from the outside and extend out from the other side of the fixing members, so that the fixing members are located at the non-end parts of the handheld part 3. It is also possible that one fixing member is arranged at the end of the handheld part 3, while the other end of the handheld part 3 bypasses the fixing member from the outside and extends out from the other side of the fixing member, so that the other fixing member is located at the non-end part of the handheld part 3.

[0066] During production, the first fixing member 11, the second fixing member 12, and the handheld portion 3 are generally integrally formed and are divided into upper and lower parts as a whole.

[0067] During assembly, the first fixing member 11 and the second fixing member 12 are respectively sleeved outside the rotating portion 2; that is, both the first fixing member 11 and the second fixing member 12 are composed of upper and lower parts. The upper and lower parts are sleeved outside the rotating portion 2, and then the upper and lower parts are assembled and fastened by screws or buckles or similar fastening structures. At this time, the handheld portion 3 is located in the middle of the rotating portion 2 or can also be located in the axial direction of the rotating portion 2. The first fixing member 11 and the second fixing member 12 can be arranged in an array along the annular rotating portion 2 or can be not arranged in an array.

[0068] The inner wall of each channel 5 is provided with a receiving cavity, and a power assistor is arranged in the receiving cavity; the power assistor abuts against the outer wall surface of the rotating portion 2. The power assistor includes a fixed shaft, the two ends of the fixed shaft are fixed in the receiving cavity, and a roller 6 is sleeved outside the fixed shaft, and the roller 6 abuts against the outer wall surface of the rotating portion 2.

[0069] Or,

[0070] The power assistor is a ball 7, the ball 7 is accommodated in the receiving cavity, and the ball 7 abuts against the outer wall surface of the rotating portion 2.

[0071] Whether the roller 6 is provided or the ball 7 is provided, the contact area between the outer wall surface of the rotating portion 2 and the inner wall surface of the channel 5 can be reduced, thereby reducing the corresponding frictional resistance. Furthermore, when the rotating portion 2 rotates, it can smoothly and fluently pass through the channel 5.

[0072] A counterweight cavity is arranged inside the rotating portion 2, and a counterweight portion 4 is accommodated inside the counterweight cavity; the counterweight portion 4 is a counterweight block or counterweight liquid or counterweight sand.

[0073] The counterweight liquid is generally water. When a hand exercise device with built-in counterweight needs to be transported or stored, the water can be poured out first, so that its own weight can be reduced, making it more convenient for transportation or storage. When a hand exercise device with built-in counterweight is needed, the water can be injected again, which is very convenient and simple. The counterweight liquid can also be other liquids.

[0074] Due to the limitation of the counterweight cavity, relative movement between the counterweight portion 4 and the rotating portion 2 will not occur. When the rotating portion 2 rotates, the counterweight portion 4 and the rotating portion 2 can only move synchronously.

[0075] When the rotating portion 2 is stationary, only part of the rotating portion 2 is accommodated in the channel 5; the remaining part is exposed outside the fixing portion 1.

[0076] In actual use, the user first grasps the handle 3 and then performs a small, circular shaking motion. Because the counterweight 4 within the rotating portion 2 is present, this swinging motion generates centrifugal force, driving the rotating portion 2 to rotate synchronously along the path. At this point, various sections of the rotating portion 2 sequentially pass through the channel 5. As the duration of this shaking motion increases, the user's hands become stronger.

[0077] Compared with existing exercise equipment, the presence of the counterweight portion 4 makes the hand exercise device with built-in counterweights very easy to use and can easily drive the rotating portion 2 to rotate. Even users with no exercise experience, or users with weak arm strength such as women and children, can easily rotate the rotating portion 2 and maintain its rotation, thereby achieving the effect of exercising the hands.

[0078] Example 2

[0079] The difference between this embodiment and embodiment 1 is that:

[0080] The fixing portion may also be a single arc-shaped fixing portion with a longer arc line (not shown in the figure).

[0081] For example, the arc length covers 25%-80% of the entire circular path. The specific value can also exceed this range and needs to be set according to actual needs.

[0082] When the number of the fixing portion is one (not shown in the figure):

[0083] The interior of the fixed part is provided with a channel with two ends communicating with each other, the channel is in an arc shape, and the arc-shaped channel provides a path for the rotating part to rotate. The rotating part is in an annular shape.

[0084] When the rotating part is stationary, part of the rotating part is accommodated in the channel; the remaining part is exposed outside the fixed part.

[0085] When the rotating part rotates, the rotating part rotates on itself and the parts of the rotating part pass through the channel in sequence.

[0086] Example 3

[0087] The difference between this embodiment and embodiment 1 is that:

[0088] When the number of the fixing parts is greater than or equal to three (not shown in the figure), the multiple fixing parts can be distributed in an array along the annular rotating part 2 or not.

[0089] The above are only the preferred embodiments of the present utility model, and thus do not limit the patent protection scope of the present utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model, directly or indirectly applied to other related technical fields, shall be included in the protection scope of the present utility model by the same token.
