Description

Technical Field

[0001] This utility model relates to the technical field of fitness training equipment, and in particular to a forearm trainer. Background Technology

[0002] Forearm training, a specialized strength training program targeting the forearm muscles, is an important component of upper limb strength training. It aims to improve grip strength, wrist stability, and forearm endurance. Current training methods typically involve using a steel pipe with ropes to suspend weights, which are then lifted by rotating the ropes while gripping the pipe. This training method primarily stimulates the forearm muscles by using the shoulders and arms to resist the weight of the pipe and weights. The alternating gripping and rotating of the pipe with both hands further strengthens wrist strength, thus comprehensively activating the forearm muscles.

[0003] However, due to the limited strength of the trainee's shoulders and arms, prolonged lifting of the steel pipe and counterweight can easily lead to loss of control, swaying of the weight, and slippage. This not only affects the training effect but also poses a safety hazard as the weight may suddenly slip out of their hands. Furthermore, when rotating the steel pipe to wind up the rope, the position of the rope is not fixed, which can cause it to shift when lifting the counterweight. This can lead to a difference in training intensity between the two arms, making the trainee prone to strain due to excessive weight on one arm caused by the shift. Utility Model Content

[0004] To address the problems mentioned above, this invention provides a forearm trainer that can be fixed to a rod for auxiliary training, thereby improving training effectiveness and reducing the occurrence of muscle strains.

[0005] The solution adopted by this utility model to solve its technical problem is: a forearm trainer, including a trainer body, the trainer body is a cylindrical structure, including a winding part arranged circumferentially in the middle of the cylindrical body and a gripping part symmetrically arranged at both ends of the winding part for gripping during training, a suspension rope for suspending weights is connected to the winding part, and an inner ring is formed at the central axis of the trainer body to allow the rod to pass through.

[0006] Furthermore, the outer diameter of the winding portion is smaller than the outer diameter of the gripping portion and is recessed to form a winding groove for winding up the suspension rope.

[0007] Furthermore, a connection port is provided on the winding part, and a connecting post is installed at the connection port along the width direction of the winding part, and the end of the suspension rope is connected to the connecting post.

[0008] Furthermore, the other end of the suspension rope connected to the connecting post is provided with a connecting buckle for fastening to the hook for training.

[0009] Furthermore, the width of the gripping part is greater than the width of the winding part, and the surface of the gripping part is provided with anti-slip texture.

[0010] Furthermore, the trainer body is split along the plane containing its central axis to form a first body and a second body with a semi-circular structure. One side edge of the first body and one side edge of the second body are hinged to each other, and a buckle assembly is connected between the other side edge of the first body and the other side edge of the second body.

[0011] Furthermore, the pull-button assembly includes a fastener hinged to the edge of the first body and a pull rod hinged to the edge of the second body. The fastener has a fastening opening, and the other end of the pull rod hinged to the second body is hinged within the fastening opening. When the fastener is pressed to pull the pull rod, the first body and the second body close around the rod.

[0012] Furthermore, the first or second main body is provided with a storage opening for storing the pull tab assembly at the position corresponding to the winding part.

[0013] Furthermore, an anti-slip pad is affixed to the inner wall surface of the trainer body.

[0014] Furthermore, a limiting installation groove is provided on the inner wall of the trainer body, and the anti-slip pad is embedded in the limiting installation groove, with the top of the anti-slip pad higher than the inner wall of the trainer body.

[0015] In summary, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model features a training device body with a columnar structure and an inner ring at the central axis. A winding section with a suspension rope connected to the center of the training device body is located in the circumference of the body. During training, the trainee can attach the training device body to the pole via the inner ring, thereby reducing the use of shoulder and upper arm strength and improving forearm training effectiveness. Furthermore, during the winding of the suspension rope through the training device body, the rope is stably wound onto the winding section in the center of the circumference of the training device body, preventing rope deviation during winding and thus avoiding strains caused by uneven training intensity in both arms.

[0017] 2. This utility model provides gripping parts on both sides of the winding part, so that when the trainee rotates the winding weight, he can not only hold the lever for more grip strength training, but also grip the gripping parts to obtain better friction and avoid slipping and injury.

[0025] To make the content of this utility model easier to understand, the present utility model will be further described below with reference to specific embodiments and accompanying drawings.

[0026] It should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "inner," and "outer" used herein to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Unless otherwise stated, "a plurality of" means two or more.

[0027] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figures 1 to 2 As shown, a forearm trainer includes a trainer body 1 that can be fixed to a rod 7. When training the forearm, the trainee can suspend a counterweight through the trainer body 1 for auxiliary training, which can improve the training effect of the forearm and wrist and avoid deviation or slippage during training, ensuring safe training. In this embodiment, the trainer body 1 has a cylindrical structure, specifically a cylinder. An inner ring 13 is provided at the central axis of the trainer body 1. The structure of the inner ring 13 is adapted to the structure of the rod 7, allowing the trainer body 1 to be fitted onto the rod 7 through the inner ring 13. This allows the trainee to perform auxiliary training through the trainer body 1 when training the forearm using the rod 7, thereby improving the training effect and avoiding injury.

[0029] like Figure 1 As shown, the outer wall of the training device body 1 in this embodiment is provided with a winding portion 11 arranged circumferentially around the training device body 1. A suspension rope 2 is connected to the winding portion 11, allowing the trainee to connect a counterweight through the suspension rope 2 to increase the training intensity during training. Furthermore, the winding portion 11 in this embodiment is located at the middle position of the training device body 1, that is, the suspension rope 2 is connected at the middle position of the training device body 1. This ensures that after the counterweight is suspended from the training device body 1, its center of gravity is located at the center of the training device body 1, so that the two sides of the training device body 1 can maintain balance, thereby ensuring the consistency of arm training.

[0030] Furthermore, the trainer body 1 in this embodiment also includes gripping portions 12 symmetrically arranged at both ends of the winding portion 11. The gripping portions 12 can be gripped by the trainee during training, thereby preventing slippage due to sweaty palms and improving safety during training. Moreover, the trainee can train directly through the gripping portions 12 without needing to mount the trainer body 1 onto the rod 7, thus reducing the use of shoulder and upper arm strength and facilitating better training of the forearm. Figures 1 to 3As shown, the width of the gripping part 12 in this embodiment is greater than the width of the winding part 11, which makes it easier for the trainee to hold the gripping part 12 during training and can improve the feel during training. In addition, the surface of the gripping part 12 in this embodiment is also provided with anti-slip texture 121, which can increase the friction between the gripping part 12 and the trainee's palm during training, thereby preventing the hand from slipping and dropping the weight during training, and ensuring the safety of training.

[0031] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the outer diameter of the winding part 11 is smaller than the outer diameter of the gripping part 12. That is, the winding part 11 sinks down and combines with the gripping parts 12 on both sides to form a winding groove 3. One end of the suspension rope 2 is connected to the winding part 11 and located in the winding groove 3. When the trainee holds the rod 7 and rotates it to wind up the suspension rope 2 for training, the suspension rope 2 can be wound into the winding groove 3 under the drive of the rod 7. This can avoid the suspension rope 2 shifting during the winding process and affecting the balance of both sides of the trainer body 1. This not only ensures the training effect, but also avoids the occurrence of safety hazards such as loss of control of movement and swaying of heavy objects caused by the shift of the suspension rope 2.

[0032] Furthermore, such as Figure 1 and Figure 3 As shown, the winding portion 11 of this embodiment has a connecting port 111 arranged along its own width direction, and a connecting post 112 is installed in the connecting port 111. One end of the suspension rope 2 in this embodiment is connected to the connecting post 112, so that the trainee can suspend the counterweight through the suspension rope 2 to increase the training intensity during training. In addition, the connecting post 112 of this embodiment is arranged along the width direction of the winding portion 11, and the width of the suspension rope 2 is adapted to the width of the winding portion 11, so that after the suspension rope 2 is connected, the suspension rope 2 can fit into the winding groove 3 formed by the combination of the winding portion 11 and the gripping portion 12. Thus, when the trainee rotates the rod 7 to perform forearm training, the suspension rope 2 can be stably fitted into the winding groove 3 during the training process, avoiding the suspension rope 2 from shifting.

[0033] like Figure 1 and Figure 2 As shown, in this embodiment, the other end of the suspension rope 2 connected to the connecting post 112 is also provided with a connecting buckle 4. The counterweight can be stably connected to the suspension rope 2 through the connecting buckle 4, thereby improving the training intensity and safety of the trainee. The connecting buckle 4 in this embodiment includes, but is not limited to, spring clips, safety buckles, or ring buckles. When the connecting buckle 4 is a spring clip or safety buckle, the suspension rope 2 can be directly fastened to the counterweight through the spring clip or safety buckle, which is a convenient connection method. When the connecting buckle 4 is a ring buckle, the suspension rope 2 can be connected to the counterweight by going around the counterweight and passing through the center of the ring buckle, which can also achieve the same technical effect.

[0034] like Figure 1 and Figure 5 As shown, to facilitate the fixed installation of the trainer body 1 on the rod 7 to assist the trainee in forearm training, the trainer body 1 is configured as a first main body 14 and a second main body 15 split along the plane of its own central axis. The projection surfaces of both the first main body 14 and the second main body 15 are semi-circular ring structures, so that when the first main body 14 and the second main body 15 are combined, a trainer body 1 with an inner ring 13 that allows the rod 7 to pass through is formed. The trainer body 1 of this embodiment can be easily installed on the rod 7 by splitting the first main body 14 and the second main body 15, and it is also easy to disassemble from the rod 7.

[0035] Specifically, in this embodiment, after the trainer body 1 is disassembled, vertical edges are formed on both sides of the first body 14 and both sides of the second body 15. One side edge of the first body 14 and one side edge of the second body 15 are hinged to each other, so that the first body 14 and the second body 15 can be rotated at the hinge position to close and form the trainer body 1, or the trainer body 1 can be disassembled by rotating at the hinge position, thereby facilitating the installation or removal of the trainer body 1 on the rod 7. A buckle assembly 5 is connected between the other side edge of the first body 14 and the other side edge of the second body 15. The two ends of the buckle assembly 5 are respectively hinged to the first body 14 and the second body 15, so that the other side edge of the first body 14 and the other side edge of the second body 15 can come closer to each other and abut against each other under the pull of the buckle assembly 5 to form the trainer body 1. When the trainer body 1 of this embodiment is installed on the rod 7, the buckle assembly 5 can be opened to separate one edge of the first body 14 and the second body 15, thereby expanding the inner ring 13 of the trainer body 1, making it easier for the rod 7 to be inserted into the inner ring 13 of the trainer body 1. After the rod 7 is inserted into the inner ring 13, the buckle assembly 5 can be used to bring the edge of the first body 14 and the edge of the second body 15 closer together, thereby reducing the inner ring 13 and locking the rod 7, thus completing the stable installation of the trainer body 1 of this embodiment. The installation method is convenient and stable, which can improve the safety of the trainee. Conversely, it is also easy to remove the trainer body 1 from the rod 7, making disassembly and assembly convenient.

[0036] like Figure 5As shown, in this embodiment, the first body 14 has an arc-shaped recess at the edge where it is hinged to the second body 15, and a connecting protrusion is provided at the position of the winding part 11 corresponding to the edge of the first body 14, and a horizontally arranged pivot hole is provided on the connecting protrusion; the second body 15 has an arc-shaped protrusion at the edge where it is hinged to the first body 14, and a connecting recess is provided at the position of the winding part 11 corresponding to the edge of the first body 14, and a horizontally arranged pivot hole is provided on the arc-shaped protrusion. When the first body 14 and the second body 15 are hinged in this embodiment, the arc-shaped protrusion at the edge of the second body 15 can be fitted into the arc-shaped recess, and the connecting protrusion of the first body 14 is fitted into the connecting recess of the second body 15. At this time, the pivot hole on the connecting protrusion and the pivot hole on the arc-shaped protrusion are coaxially corresponding. By inserting a connecting pivot into the pivot hole, the hinge between the first body 14 and the second body 15 can be realized. At the same time, both the first body 14 and the second body 15 can rotate around the pivot as the axis, thereby realizing the closing and unfolding of the first body 14 and the second body 15.

[0037] like Figures 3 to 5 As shown, in order to achieve a stable fastening between the first main body 14 and the second main body 15, thereby improving the locking strength of the trainer body installed on the rod 7, the buckle assembly 5 in this embodiment is configured to include a fastening member 51 and a pull rod member 52 that are hinged to each other. The fastening member 51 in this embodiment has a fastening opening 511 in the middle, and one end of the pull rod member 52 is hinged to the middle of the fastening opening 511, so that when the fastening member 51 and the pull rod member 52 are fastened, the front part of the pull rod member 52 can be fitted into the fastening opening 511, thereby shortening the overall length of the fastening assembly. In this embodiment, the other end of the fastener 51 and the pull rod 52 is hinged to the edge of the first body 14, while the other end of the pull rod 52 and the fastener 51 is hinged to the edge of the second body 15. When the fastening assembly is not closed, the edges of the first body 14 and the second body 15 that are not hinged to each other can be separated by the action of the fastener 51 and the pull rod 52, thereby expanding the inner ring 13 of the trainer body 1 to facilitate installation onto the rod 7. When the fastening assembly is closed, the fastener 51 is pressed and the pull rod 52 is pulled. The front end of the pull rod 52 is fitted into the fastening opening 511 under the action of the hinge, thereby shortening the overall length of the fastening assembly. At this time, the second body 15 can approach the first body 14 under the pull of the pull rod 52, and then merge with the first body 14 to form the trainer body 1. Thus, the first body 14 and the second body 15 of this embodiment are closed and locked around the rod 7 to achieve stable installation of the trainer body 1.

[0038] Furthermore, to further improve the stability of the trainer body after it is installed on the rod 7, an anti-slip pad 6 is provided on the inner ring 13 wall of the trainer body. When the first body 14 and the second body 15 are locked onto the rod 7 by the buckle assembly 5, the anti-slip pad 6 can fill the gap between the rod 7 and the inner ring 13, thereby improving the locking strength of this embodiment. In addition, the anti-slip pad 6 in this embodiment is made of silicone, which can also increase the friction between the anti-slip pad and the surface of the rod 7, thereby preventing the trainer body 1 and the rod 7 from rotating and slipping, and improving the safety of training.

[0039] Specifically, in this embodiment, a limiting installation groove 131 is provided on the inner ring 13 wall of the trainer body 1. The anti-slip pad 6 can be fitted into the limiting installation groove 131, which not only improves the installation strength of the anti-slip pad 6, but also prevents the anti-slip pad 6 from shifting and affecting the locking strength of the trainer body 1. After the anti-slip pad 6 is installed in the limiting installation groove 131, the top plane of the anti-slip pad 6 is higher than the inner ring 13 wall of the trainer body 1, which facilitates filling the gap between the rod 7 and the inner ring 13 and improves the locking strength of this embodiment. The inner wall surfaces of the first body 14 and the second body 15 in this embodiment are both provided with anti-slip pads 6, which can effectively improve the locking strength after the first body 14 and the second body 15 are locked.

[0040] In addition, such as Figure 4 and Figure 5 As shown, in order to avoid the buckle assembly 5 interfering with the winding of the suspension rope 2, the first main body 14 or the second main body 15 in this embodiment is also provided with a storage opening 16 at the position corresponding to the winding part 11. When the buckle 51 pulls the pull rod 52 to buckle, the two can be fitted into the storage opening 16 so that they are at the same height as the winding part 11, thereby facilitating the stable winding of the suspension rope 2 during the trainee's training.

[0041] In summary, this embodiment features a training device body 1 with a cylindrical structure and an inner ring 13 at its central axis. A winding section 11, connected to a suspension rope 2, is located in the center of the circumference of the training device body 1. This allows the training device body 1 to be fixed to the rod 7 via the inner ring 13 when the trainee is training their forearms. This prevents slippage when the trainee grips the rod 7 and rotates to wind up the suspension rope 2, ensuring the effectiveness of forearm training. Furthermore, the suspension rope 2 is stably wound onto the winding section 11 in the center of the circumference of the training device body 1 during winding, preventing deviation during winding and avoiding imbalances in the intensity of the exercise on both arms. Additionally, this embodiment provides grip sections 12 on both sides of the winding section 11, allowing the trainee to grip the grip sections 12 with both hands to rotate and wind up weights for wrist strength training. This also prevents slippage and safety hazards, ensuring safe training for the trainee.

[0042] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
