Technical Field
[0001] This utility model relates to the field of fitness equipment technology, specifically to a manual fitness device. Background Technology
[0002] The following problems often occur in existing hand fitness equipment: On the one hand, many hand fitness equipment have high manual resistance settings, which makes it very difficult for some people with relatively weak strength, such as the elderly, patients in the rehabilitation period, and women, to use them. They may find it difficult to persist in exercising for a long time, and may even damage their hand joints and muscles due to excessive force, thus losing confidence and motivation in hand activities. On the other hand, some hand fitness equipment is not scientifically designed, with limited range of motion for the hands, and cannot fully mobilize the movement of various joints in the hands, namely the upper arm, forearm and wrist. For some people who suffer from stiff and tired hands due to prolonged use of keyboards and mice, there is a need for a comprehensive exercise to relieve tension in the wrist, upper arm and forearm, enhance overall coordination and stability, and thus improve hand health.
[0003] For some rehabilitation patients who need to exercise with one hand, or in environments with limited space, it is not convenient to disassemble the equipment for use on one side. This not only reduces the flexibility and applicability of the equipment, but also brings inconvenience to the user.
[0004] For example, patent application number 202021768518.7, published on January 22, 2021, discloses a hand-cranked cart, including a column, a main frame on the column, side cover plates on both sides of the main frame via sealing rings, a pulley inside the main frame, a central shaft in the pulley, and rocker arms at both ends of the central shaft passing through the side cover plates. A belt is fitted onto the pulley, and the other end of the belt is fitted onto the shaft of a magnetic control wheel. The magnetic control wheel is mounted inside the main frame via a flywheel. A magnet seat is provided between the pulley and the magnetic control wheel, and the distance between the magnet seat and the magnetic control wheel is adjustable. The cart uses a relatively stable and reliable magnetic resistance source to provide resistance, and the distance between the magnetic control wheel and the magnet seat is adjusted by adjusting the tightening position of the bolts, thereby adjusting the resistance. The overall waterproof and sealing performance ensures long-term outdoor use.
[0005] Although the above-mentioned hand-cranked carts use magnetic resistance to provide resistance and adjust the distance between the magnetic control wheel and the magnet base by adjusting the locking position of the bolt to change the resistance, the main movement method in the above-mentioned carts is to rotate the pulley with a rocker arm, which in turn drives the magnetic control wheel to generate resistance. A user seat needs to be set on the device, and the position needs to meet the needs of arm movement. For people with weaker strength, such as the elderly and patients in the rehabilitation period, it may not be convenient to sit in the seat to exercise, which makes it inconvenient to use. In addition, since the rocker arm is held and rotated by the hand, it can only realize the rotation of the hand holding part around the rotation axis. This focuses more on the flexion and extension movements of the arm and wrist, and the effect on arm swing is relatively poor. Summary of the Invention
[0006] This utility model provides a manual fitness equipment that is effective and easy to use.
[0007] To achieve the above objectives, the technical solution of this utility model is as follows: a manual fitness equipment, including a base, wherein the base is provided with a rotating disk assembly, the rotating disk assembly includes a main rotating disk, the main rotating disk is rotatably connected to the base through a main rotating shaft, rockers are provided on both sides of the main rotating shaft, and a rotating arm is provided on at least one of the rockers, one end of the rotating arm is fixedly connected to the main rotating shaft, the other end of the rotating arm is rotatably connected to the rocker, and the other end of the rotating arm is detachably connected to the rocker.
[0008] In the above configuration, the main rotating disk is connected to the main rotating shaft, which is connected to the rotating arm via a rocker arm. When the main rotating disk is rotated using the rotating arm, since the rotating shaft is fixedly connected to the rocker arm, while the rotating arm is rotatably connected to the rocker arm, the user grips the rotating arm and drives the rocker arm to rotate around the main rotating shaft. Because the gripping part of the hand extends from the rocker arm to the rotating arm, the range of motion of the gripping part is increased when driving the rocker arm to rotate around the rotating arm. This is unlike the existing technology where the gripping part of the hand always rotates around the main rotating shaft, thus preventing an increase in the range of motion. This increases the range of motion of the arm, resulting in better activity. This not only reduces the user's physical exertion but also reduces the potential risk of injury due to excessive force. This is especially important for users with weak strength or those who need hand rehabilitation, as they can gradually increase the strength of their hands and arms within a comfortable range. In addition, the addition of a detachable rotating arm allows users to choose different lengths of rotating arms and different positions and heights of seats according to their arm length and height, thus adapting to the usage needs of different users in different scenarios.
[0009] Furthermore, a rotating assembly is provided between the rotating arm and the rocker arm.
[0010] The above setup achieves a rotatable connection between the rotating arm and the rocker arm through a rotating assembly between them, and then a fastening assembly is provided between the rocker arm and the rotating arm to achieve a detachable connection.
[0011] Furthermore, the base includes a supporting column, and the rotating disk assembly includes a rotating disk. The supporting column is rotatably connected to the rotating disk, and the rotating disk is connected to the main rotating disk via a transmission belt. A magnet seat is also provided on one side of the rotating disk, and an adjustment hole is provided at the bottom of the magnet seat. A fixing baffle is provided on the base, and the fixing baffle has a fixing hole. An adjustment device is provided between the adjustment hole and the fixing hole. The adjustment device includes an adjustment bolt, an adjustment elastic element, and an adjustment nut. The adjustment bolt passes through the adjustment hole and the adjustment elastic element in sequence, and then passes through the fixing hole to connect with the adjustment nut.
[0012] In the above configuration, the rotating disk is a magnetic rotating disk, which flexibly adjusts the distance between the rotating disk and the magnet base to change the magnitude of the magnetic resistance. In the specific adjustment process, simply rotate the adjusting nut to bring the adjusting bolt closer to or away from the fixing hole to complete the setting of the resistance of the rotating disk. When the desired position is reached, the adjusting elastic element is located between the magnet base and the fixed baffle. Therefore, when the adjusting elastic element is compressed, due to the elasticity of the adjusting elastic element, the elastic force of the adjusting elastic element is applied to the fixed baffle and the magnet base, thus ensuring that the relative position between the two does not change. Furthermore, the rotating disk is connected to the main rotating disk via a transmission belt, so the resistance from the rotating disk can be transmitted to the main rotating disk.
[0013] Furthermore, main rotating protrusions are provided on both sides of the main rotating shaft, and a mounting groove matching the main rotating protrusions is provided on one side of the rocker arm.
[0014] The above settings, through the matching of the main rotating protrusion and the mounting groove, ensure that the joystick always rotates synchronously with the main rotating shaft during movement. This effectively reduces errors and wobbling during movement, making the movement between the arm and the main rotating disk more precise and consistent, facilitating installation and reducing alignment time.
[0015] Furthermore, a fastening assembly for detachable connection is provided between the rocker arm and the rotating arm. The fastening assembly includes a fastening screw. A mounting part is provided on one side of the rotating arm. The mounting part is hollow and has a mounting hole. The fastening screw passes through the mounting hole and is fixedly connected to the other side of the rocker arm. A fastening groove is provided on the surface of the fastening screw.
[0016] With the above configuration, the fastening screw passes through the mounting hole and connects to the rocker arm, making the installation and disassembly of the rotating arm simple and quick. Users can easily tighten or loosen the fastening screw by inserting a tool such as a screwdriver into the fastening groove, thereby achieving quick disassembly and installation of the rotating arm. It is suitable for rehabilitation patients who need to exercise with one hand. Users can easily disassemble the device for single-sided use, improving the flexibility and applicability of the equipment.
[0017] Furthermore, a connecting part is provided on the other side of the rocker arm, and the connecting part is provided with a connecting hole, and the fastening screw is fixedly connected to the connecting hole.
[0018] The above setup, with the fastening screw connected to the connecting hole, ensures a tight and stable connection between the rotating arm and the rocker arm, effectively preventing the rotating arm from loosening or falling off during operation.
[0019] Furthermore, the rotating assembly includes a rotating bearing, and mounting blocks extending toward the center of the mounting hole are respectively provided on both sides of the mounting hole. The mounting blocks and the surface of the mounting part form a mounting groove, and the rotating bearing is fixed in the mounting groove.
[0020] With the above configuration, the rotating bearing is placed in the mounting groove, which provides stable support for the rotating bearing, ensuring that the rotating bearing always stays in the correct position during movement, thereby reducing shaking and errors. The rotating bearing is a conventional rotating bearing with an outer ring and an inner ring, and the outer ring can rotate relative to the inner ring. The outer ring of the rotating bearing is snapped and fixed in the mounting groove on the side near the rocker arm. Then, one end of the fastening screw passes through the inner ring of the mounting groove and is fixedly connected to the connecting hole of the rocker arm. The rotating bearing is fixedly connected to the inner ring by the fastening screw, and the rotation of the outer ring relative to the inner ring realizes the rotational connection between the rotating arm and the rocker arm.
[0021] Furthermore, a rotating gripper is provided on the other side of the rotating arm.
[0022] The above settings provide a convenient grip for users, allowing them to more easily hold the rotating arm during exercise. Therefore, by setting up a rotating grip, users can hold the rotating arm more firmly, thus maintaining a stable posture during exercise.
[0023] Furthermore, the joystick has two or more connection holes along its length.
[0024] The above settings, by setting multiple connection holes on the joystick, allow for adjustment of the length of the connection between the joystick and the rotating arm by connecting the rotating arm to different connection holes.
[0025] Furthermore, the rotating arm is a telescopic rotating arm.
[0026] The above settings allow for easy adjustment of the length of the rotating arm. Attached Figure Description

Detailed Implementation
[0037] Example 1.
[0038] like Figure 1-9As shown, a seated manual fitness equipment includes a base 1, a rotating disk assembly 7 on the base 1, a main rotating disk 71 on the rotating disk 71, the main rotating disk 71 being rotatably connected to the base 1 via a main rotating shaft 711, rocker arms 4 on both sides of the main rotating shaft 711, at least one of the rocker arms 4 being provided with a rotating arm 2, the rotating arm 2 being rotatably connected to the rocker arm 4, and the rotating arm 2 being detachably connected to the rocker arm 4.
[0039] A rotating assembly and a fastening assembly are provided between the rotating arm 2 and the rocker arm 4.
[0040] A rotating gripper 23 is provided on one side of the rotating arm 2. The rotating gripper 23 provides a convenient grip for the user, making it easier for the user to grasp the rotating arm 2 during exercise. Therefore, by setting the rotating gripper 23, the user can hold the rotating arm 2 more firmly and maintain a stable posture during exercise.
[0041] like Figure 2-4 As shown, the base 1 includes a support column 13, and the rotating disk assembly 7 includes a rotating disk 72. The support column 13 is rotatably connected to the rotating disk 72. The rotating disk 72 is connected to the main rotating disk 71 via a transmission belt. A magnet seat 6 is also provided on one side of the rotating disk 72. An adjustment hole 61 is provided at the bottom of the magnet seat 6. A fixing baffle 8 is provided on the base 1. The fixing baffle 8 is provided with a fixing hole 81. An adjustment device 5 is provided between the adjustment hole 61 and the fixing hole 81. The adjustment device 5 includes an adjustment bolt 51, an adjustment elastic element 52, and an adjustment nut 53. The adjustment bolt 51 passes through the adjustment hole 61 and the adjustment elastic element 52 in sequence, and then passes through the fixing hole 81 to connect with the adjustment nut 53. The disc 72 is made of iron, which generates a magnetic force between the rotating disc 72 and the magnet base 6. The distance between the rotating disc 72 and the magnet base 6 can be flexibly adjusted to change the magnitude of the magnetic resistance. In the specific adjustment process, simply rotate the adjusting nut 53 to move the adjusting bolt 51 closer to or further away from the fixing hole 81 to complete the setting of the resistance of the rotating disc 72. When the desired position is reached, the adjusting elastic element 52 is located between the magnet base 6 and the fixing baffle 8. Therefore, when the adjusting elastic element 52 is compressed, due to the elasticity of the adjusting elastic element 52, the elastic force of the adjusting elastic element 52 is applied to the fixing baffle 8 and the magnet base 6, thus ensuring that the relative position between the two does not change. Furthermore, the rotating disk 72 is connected to the main rotating disk 71 via a transmission belt, so the resistance from the rotating disk 72 can be transmitted to the main rotating disk 71.
[0042] like Figure 4 , 6As shown in Figure 7, main rotating protrusions 7111 are provided on both sides of the main rotating shaft 711, and a mounting groove 42 matching the main rotating protrusions 7111 is provided on one side of the rocker arm 4. By matching the main rotating protrusions 7111 and the mounting groove 42, it can be ensured that the rocker arm 4 always rotates synchronously with the main rotating shaft 711 during the movement, which can effectively reduce errors and shaking during the movement, making the movement between the arm and the main rotating disk 71 more precise and consistent, facilitating installation and reducing alignment time.
[0043] The main rotating protrusion 7111 has a cubic structure. The cubic main rotating protrusion 7111 has a uniform geometric shape and symmetrical force distribution, which can ensure that the main rotating protrusion 7111 maintains a stable connection when subjected to forces from all directions during movement. Compared with other irregular shapes, the cubic structure has less deformation under force, thereby improving the stability and reliability of the overall structure. The cubic main rotating protrusion 7111 has four planes. The fact that the four planes are the same allows the main rotating protrusion 7111 to reduce the alignment time. For example, the mounting groove 42 can be installed opposite to any one of the faces of the main rotating protrusion 7111.
[0044] like Figure 5 As shown, the base 1 also includes a base housing 11, which includes a through hole 111 for the main rotating shaft 711 to extend out. The base housing 11 provides physical protection for the main rotating shaft 711 and other components inside the base 1, preventing dust, debris and moisture from entering the interior of the base 1, thereby reducing wear and corrosion on the internal mechanical parts.
[0045] like Figure 2 , 8 As shown in Figure 9, the fastening assembly includes a fastening screw 3. A mounting part 21 is provided on one side of the rotating arm 2. The mounting part 21 is hollow and has a mounting hole 211. The fastening screw 3 passes through the mounting hole 211 and connects to the other side of the rocker arm 4. A fastening groove 31 is provided on the surface of the fastening screw 3. The fastening screw 3 passes through the mounting hole 211 and is fixedly connected to the rocker arm 4, making the installation and disassembly of the rotating arm 2 simple and quick. Users can easily tighten or loosen the fastening screw 3 by inserting a tool such as a screwdriver into the fastening groove 31, thereby achieving quick disassembly and installation of the rotating arm 2. This is suitable for rehabilitation patients who need to exercise with one hand. Users can easily disassemble the device for single-sided use, improving the flexibility and applicability of the equipment.
[0046] A connecting part 41 is provided on the other side of the rocker arm 4. The connecting part 41 is provided with a connecting hole 411. The fastening screw 3 is fixedly connected to the connecting hole 411. In one embodiment, one end of the fastening screw 3 is fixedly connected to the connecting hole by providing a fastening nut, or one end of the fastening screw is provided with a thread, and the connecting hole is provided with a thread to fix the fastening screw to the connecting hole. The connection between the fastening screw 3 and the connecting hole 411 can ensure that the connection between the rotating arm 2 and the rocker arm 4 is tight and stable. During the movement, it can effectively prevent the rotating arm 2 from loosening or falling off.
[0047] The rotating assembly includes a rotating bearing 22, and mounting blocks 2111 are respectively provided on both sides of the mounting hole 211. The mounting blocks 2111 and the surface of the mounting part 21 form a mounting groove. The rotating bearing 22 is matched with the mounting groove and placed in the mounting groove. The mounting groove provides stable support for the rotating bearing 22, ensuring that the rotating bearing 22 always stays in the correct position during the movement, thereby reducing shaking and error. The rotating bearing 22 is a rotating bearing with an outer ring and an inner ring in the prior art, and the outer ring can rotate relative to the inner ring. The outer ring of the rotating bearing is snapped and fixed in the mounting groove. Then, one end of the fastening screw passes through the inner ring of the mounting groove and is fixedly connected to the connection hole of the rocker arm. The rotating bearing is fixedly connected to the inner ring by the fastening screw, and the rotation of the outer ring relative to the inner ring realizes the rotational connection between the rotating arm and the rocker arm.
[0048] The working principle of this utility model is as follows: A main support column 12 is provided on the base, and the main support column 12 is rotatably connected to the main rotating disk 71. The main rotating disk 71 is connected to the main rotating shaft 711, and the main rotating shaft 711 is connected to the rotating arm 2 through the rocker arm 4. Since the rotating shaft 722 is fixedly connected to the rocker arm 4, and the rotating arm 2 is rotatably connected to the rocker arm 4, the user can hold the rotating arm and drive the rocker arm 4 to rotate around the main rotating shaft 711. Since the gripping part of the hand extends from the rocker arm 4 to the rotating arm 2, the swing range of the gripping part is increased when the rocker arm is driven to rotate around the rotating arm. This is not the case in the prior art where the gripping part of the hand is always set to rotate around the main rotating shaft, thus preventing an increase in the swing range. This increases the swing range of the arm, resulting in better activity. This not only reduces the user's physical exertion but also reduces the potential risk of injury caused by excessive force. This is especially important for users with weak strength or who need hand rehabilitation, as they can gradually increase the strength of their hands and arms within a comfortable range. In addition, the addition of a detachable rotating arm 2 allows users to choose different lengths of rotating arms and different positions and heights of seats according to their arm length and height, thus adapting to the usage needs of different users in different scenarios.
[0049] Example 2.
[0050] The only difference between this embodiment and Embodiment 1 is that multiple connecting holes are spaced apart along the length of the rocker arm. This allows for connection between the rotating arm and the rocker arm at different positions.
[0051] Example 3.
[0052] The only difference between this embodiment and Embodiment 1 is that the rocker arm is set as a telescopic rod structure. Specifically, the telescopic structure is the existing telescopic rod structure, or it can be a telescopic structure similar to an umbrella handle. The telescopic structure can also be achieved by providing through holes along the length of the rods on two sleeved rods. After the two rods are sleeved together and the through holes are aligned, a pin is inserted into the through holes to fix them. This achieves the adjustment of the telescopic rod length. The specific telescopic rod structure is existing technology and will not be described in detail here.
