Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, specifically relating to a U-shaped arm strength trainer. Background Technology

[0002] Currently, fitness has become a common form of exercise in people's lives, and there is a wide variety of fitness equipment available. Arm exercisers are a very common type of fitness equipment, and the double-bar grip type is a relatively common one, with a simple structure and easy operation.

[0003] However, the angle between the handle and the frame of the existing arm exerciser cannot be adjusted, so the angle between the handle and the frame cannot be adjusted according to the different needs of the user. Utility Model Content

[0004] This invention provides a U-shaped arm strength trainer, which aims to solve the problem that the angle between the handle and the frame of the arm strength trainer cannot be adjusted in the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A U-shaped arm exerciser includes a frame and a handle disposed on the frame;

[0007] The frame is equipped with an elastic element, and there are two handles, which are located at opposite ends of the elastic element.

[0008] The handle is mounted on the frame via an angle adjustment mechanism. There are two handles, both of which are mounted on the frame via the angle adjustment mechanism.

[0009] A further improved solution: The angle adjustment mechanism includes a first adjustment disc disposed on the handle and a second adjustment disc disposed on the frame. The first adjustment disc and the second adjustment disc are rotatably connected. By operating the first adjustment disc, the angle of the handle relative to the frame can be adjusted by placing the first adjustment disc and the second adjustment disc at different angles. The angle adjustment mechanism also includes a locking seat for locking the angle of the handle relative to the frame.

[0010] Based on the above technical solution, users can easily adjust the angle between the handle and the frame by operating the first adjustment dial. This flexibility allows users to choose the most suitable training angle according to their individual training needs and muscle condition. Different training angles can specifically target different muscle groups. This design allows users to achieve diverse training goals with a single arm exerciser. The angle adjustment mechanism is simple and convenient to operate; users only need to gently rotate the first adjustment dial and lock the locking seat to complete the angle adjustment. This design makes the arm exerciser more convenient to use and store, saving users time and effort.

[0011] A further improved solution: The first adjusting plate has a first adjusting hole along its circumference, and the second adjusting plate has a second adjusting hole along its circumference. The locking seat has a locking pin that passes through the first adjusting hole and the second adjusting hole. The handle has a base. The first adjusting plate and the second adjusting plate are both located between the locking seat and the base. The locking seat has a button. An elastic element is provided between the button and the first adjusting plate. The elastic element pulls the button, causing the locking pin to pass through the first adjusting hole and the second adjusting hole. By pressing the button and overcoming the elastic force of the elastic element, the locking pin disengages from the first adjusting hole, causing the locking seat to release the first adjusting plate and the second adjusting plate.

[0012] Based on the above technical solution: Both the first and second adjustment discs are equipped with circumferential adjustment holes, allowing users to precisely adjust the angle between the handle and the frame by selecting different hole positions. This design ensures the accuracy and reliability of angle adjustment. After the locking pin passes through the first and second adjustment holes, it securely connects the first and second adjustment discs together, thus achieving stable locking of the angle between the handle and the frame. This design ensures safety and stability during training. The button and elastic element design on the locking seat allows users to lock and release the locking pin with simple pressing and releasing operations. This design simplifies the operation process and improves efficiency. The tension of the elastic element causes the button to automatically reset after release, thereby driving the locking pin back to the locked position. This design not only improves the convenience of operation but also ensures the reliability of the locking mechanism during long-term use.

[0013] A further improved solution: The locking seat is provided with a connecting post, the first adjusting plate is rotatably connected to the second adjusting plate through the connecting post, both the first adjusting plate and the second adjusting plate are provided with through holes that cooperate with the connecting post, and the button is provided on the locking seat through the connecting post.

[0014] Based on the above technical solution: the first adjusting plate, the second adjusting plate, and the locking seat are tightly connected together by a connecting column, making the entire angle adjustment mechanism more compact and reducing gaps and the possibility of loosening between components. The connecting column, as the axis of rotation, ensures the stability of the first and second adjusting plates when adjusting the angle. Simultaneously, the through-hole design makes the connection between components more robust, preventing wear and loosening due to long-term use. The matching design of the connecting column and the through-hole allows the first and second adjusting plates to rotate smoothly around the connecting column, providing users with a smoother operating experience when adjusting the angle. Users can simply rotate the first adjusting plate to adjust the angle between the handle and the frame without complex disassembly and reassembly. This design improves the flexibility and convenience of use.

[0015] A further improved solution: There are at least two locking pins, which are evenly distributed along the circumference of the locking seat.

[0016] Based on the above technical solution: at least two locking pins are evenly arranged along the circumference of the locking seat, meaning that the number of connection points between the handle and the frame increases. This multi-point fixing method can more effectively prevent the handle from shaking or shifting during training, enhancing the stability of the locking. The even distribution of locking pins ensures that the handle receives force evenly, avoiding damage or loosening of components due to excessive force at a single point. This design extends the lifespan of the arm strength trainer and improves training safety. The design of multiple locking pins is usually combined with buttons, allowing users to simultaneously unlock or lock all locking pins with simple operations. This design simplifies the operation process and improves ease of use.

[0017] A further improved solution: The angle adjustment mechanism includes a first connecting seat disposed on the frame and a second connecting seat disposed on the handle. The first connecting seat and the second connecting seat are rotatably connected. The angle of the handle relative to the frame is adjusted by adjusting the angle of the first connecting seat relative to the second connecting seat. A locking device is provided between the first connecting seat and the second connecting seat to lock the angle of the handle relative to the frame.

[0018] Based on the above technical solution, users can easily adjust the angle between the handle and the frame by adjusting the relative angle between the first and second connecting seats. This design allows users to choose the most suitable training angle according to their personal preferences, training goals, and muscle condition. Different training angles can target different muscle groups. For example, adjusting to a smaller angle can focus on training the triceps, while a larger angle is more suitable for training the pectoralis major and deltoids. This design allows users to meet diverse training needs with a single arm exerciser. A locking device securely locks the first and second connecting seats together after the handle angle is adjusted, ensuring stability and safety during training. The locking device is typically made of high-strength materials and can withstand high-intensity training pressure. The locking device design effectively prevents accidental loosening of the first and second connecting seats during training. Even under prolonged, high-intensity training, users can exercise with confidence without worrying about safety issues caused by loose parts.

[0019] A further improved solution: The locking device includes a rotating shaft, the first connecting seat and the second connecting seat are rotatably connected by the rotating shaft, the rotating shaft is slidably connected to the first connecting seat, the rotating shaft includes a spline end, the spline end of the rotating shaft is further provided with a spline, the first connecting seat is provided with a first keyway that mates with the spline, the second connecting seat is provided with a second keyway that mates with the spline, the rotating shaft passes through the first connecting seat, and the spline end of the rotating shaft extends into the second keyway, the angle of the handle relative to the frame is adjusted by placing the first connecting seat and the second connecting seat at different angles and making the first keyway mate with the spline on the rotating shaft.

[0020] Based on the above technical solution: the spline on the rotating shaft can mate with the first keyway on the first connecting seat and the second keyway on the second connecting seat to form multiple fixed angular positions. Users can adjust the angles of the first and second connecting seats relative to the rotating shaft, allowing the spline to mate with different keyways, thus achieving precise angle adjustment of the handle relative to the frame. When the spline mates with the keyway, the rotating shaft cannot continue to rotate due to the limiting effect of the keyway, thus achieving stable locking between the first and second connecting seats. This design ensures the stability of the handle angle during training, avoiding decreased training effectiveness or safety issues caused by angle changes. Users can adjust the angle between the first and second connecting seats through simple rotation, without the need for complex disassembly and reassembly. This design simplifies the operation process and improves efficiency. Because the relationship between the spline and the keyway is intuitive and easy to understand, users can easily find the desired angle position when adjusting the angle, without the need for tedious debugging and calibration work.

[0021] A further improved solution: An elastic element is provided between the rotating shaft and the second connecting seat to push the rotating shaft so that the spline simultaneously engages with the first keyway on the first connecting seat and the second keyway on the second connecting seat. The length of the second keyway is not less than the length of the spline. By pressing the rotating shaft, the spline disengages from the first keyway and enters the second keyway, causing the locking device to release the first connecting seat and the second connecting seat.

[0022] Based on the above technical solution: when the rotating shaft is pushed by the elastic element, the spline simultaneously engages with the first keyway on the first connecting seat and the second keyway on the second connecting seat. This engagement ensures a stable connection between the first and second connecting seats, thereby achieving a stable locking of the angle between the handle and the frame. Users can easily release the locking device by pressing the rotating shaft to disengage the spline from the first keyway, thus releasing the first and second connecting seats. This design simplifies the operation process and improves ease of use. Users can adjust the angle between the handle and the frame as needed and fix it using the locking mechanism. This design allows the arm exerciser to adapt to the needs of users with different body types, training habits, and training intensities.

[0023] A further improved solution: The rotating shaft is provided with a button for easy pressing of the rotating shaft, and the spline and the rotating shaft are an integral structure.

[0024] Based on the above technical solution: the button design allows users to easily move the rotating shaft by pressing it, thereby controlling the disengagement and engagement of the spline and the first keyway. This one-button operation greatly simplifies the operation process and improves ease of use. The buttons typically have clear markings and locations, allowing users to intuitively understand how to operate them. This design reduces the difficulty of operation, enabling even first-time users to quickly get started. The spline and rotating shaft are a single integrated structure, ensuring a secure connection between them and preventing loosening or damage due to long-term use. Simultaneously, the integrated structure also improves the strength and durability of the components. Compared to a separate structure, the integrated structure reduces the number of connection points between components, thereby reducing the possibility of malfunctions. This helps ensure the stability and reliability of the arm strength trainer during long-term use.

[0025] A further improved solution: The first connecting seat is provided with a shaft hole that mates with the rotating shaft, and the button located on the rotating shaft extends out of the first connecting seat through the shaft hole in a direction away from the second connecting seat.

[0026] Based on the above technical solution: the shaft hole design ensures that the rotating shaft can be stably mounted on the first connecting seat and can rotate smoothly when needed. This tight fit helps reduce friction and wear between components, improving the stability and durability of the entire mechanism. The button extends from the first connecting seat through the shaft hole, allowing the user to easily press the button to control the movement of the rotating shaft. This design not only improves the convenience of operation but also makes the entire mechanism more compact, effectively utilizing space. Users can easily move the rotating shaft and engage or disengage the spline and keyway by pressing the button extending from the first connecting seat. This one-button operation simplifies the operation process and improves ease of use.

[0027] The beneficial effects of this utility model are as follows:

[0028] This invention features an angle adjustment mechanism, allowing users to easily adjust the angle between the handle and the frame according to their individual muscle strength, training goals, and preferences. This personalized setting helps improve training effectiveness and meets the diverse needs of different users. The angle adjustment function allows users to try different training angles, thereby working different muscle groups. This variety of training methods helps increase users' training interest and motivation, promoting comprehensive muscle development.

[0029] By adjusting the handle angle, users can alter the way muscle groups are stressed, resulting in a more comprehensive workout. This optimization helps improve training effectiveness and reduces the risk of muscle injury due to uneven stress. The angle adjustment mechanism allows users to adjust the training difficulty according to their own conditions, avoiding sports injuries caused by improper angles or excessive training intensity. Simultaneously, a stable locking mechanism ensures safety during training.

[0030] By adjusting the handle angle, users can find the most suitable training posture, reducing fatigue and discomfort caused by maintaining an uncomfortable posture for extended periods. This increased comfort helps users stay in a training state for longer. Because the handle angle is adjustable, this U-shaped arm exerciser can accommodate users of different body types, ages, and training levels. This broad applicability makes the product more competitive in the market. Attached Figure Description
