Description

Technical Field

[0001] This utility model relates to the field of speed arm device technology, specifically to a speed arm device that facilitates adjustment of rotational resistance. Background Technology

[0002] With increasing urbanization and a faster pace of life, many people are in a sub-healthy state, making exercise increasingly important. Traditional arm exercises include dumbbells and arm curl machines. For example, as shown in Taiwan Patent Application No. M424160, its structure mainly consists of two rotating discs on the outer rings of the main body, each with a handle. By gripping the handles with both hands or one hand and twisting, rotating, or swinging the discs in various directions, one can simulate basic Tai Chi movements, continuous punching motions in boxing, and inertial swinging movements, thus exercising the arm muscles, wrists, elbows, and shoulder joints.

[0003] However, the two discs of the aforementioned arm exerciser can rotate freely and smoothly within the two outer rings of the main body, thus providing the same training effect for everyone. However, because everyone's physical condition and training time are different, the required level of exercise will also vary. Currently, this type of conventional arm exerciser can only produce different levels of exercise by increasing or decreasing the overall weight. Using the increase or decrease of the overall weight to produce different levels of exercise not only limits the direction and effect of the exercise, but also necessitates preparing arm exercisers of different weights for users of different levels or stages. This results in very high costs for purchasing arm exercisers and also takes up a lot of space. Utility Model Content

[0004] The purpose of this invention is to provide a speed arm device that is easy to adjust the rotational resistance, thereby solving the problems of existing technologies that cannot adjust the rotational resistance according to different users to achieve different training effects, require speed arm devices of different weights, and have high operating costs.

[0005] To solve the above-mentioned technical problems, this utility model achieves this through the following technical solution:

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-3As shown, a speed arm device with adjustable rotational resistance includes a connecting base 1, with rotating bases 2 symmetrically arranged on both sides of the connecting base 1. A turntable is rotatably mounted on the rotating base 2, and a handle 3 is disposed inside the turntable. A resistance adjustment assembly is provided on the connecting base 1, including an adjusting element 4, a slide 5, and two pins 6. The adjusting element 4 passes through the upper end of the connecting base 1, and a fixing rod 7 is connected to the lower end of the connecting base 1. An elastic element 8 is sleeved on the fixing rod 7, and the other end of the elastic element 8 is in contact with the lower end of the slide 5. The two pins 6 are symmetrically located on both sides of the slide 5, and one end of the pin 6 passes through the opposite side. The rotating seat 2 in the corresponding position contacts the damping element on the inner wall of the rotating seat 2. The other end is provided with a connector 601. A connecting rod 9 is movably connected to the connector 601. The other end of the connecting rod 9 is movably connected to the slide 5. The upper end of the slide 5 is in contact with the adjusting member 4. By operating the adjusting member 4, the slide 5 is moved up and down, which drives the two ejector pins 6 to move linearly relative to the corresponding rotating seat 2. The moving direction of the ejector pins 6 is perpendicular to the moving direction of the slide 5. A first protective cover 10 is connected to one side of the connecting seat 1, and a second protective cover 11 is provided on the other side, which is detachably connected to the first protective cover 10.

[0020] In use, simply operate the adjusting component 4, which will push the slide 5 downwards. At this time, the two ends of the connecting rod 9 form an oblique line. The sliding of the slide 5 will cause the end of the connecting rod 9 connected to the slide 5 to also slide down, thereby pushing the ejector pin 6 towards the rotating seat 2. That is, the ejector pin 6 will squeeze the damping component, and the damping component will elastically deform inward to squeeze the turntable, increasing the damping force provided to the turntable. In this way, the rotational resistance between the turntable and the rotating seat 2 can be adjusted to allow for different levels of exercise. The fixed rod 7 and the elastic component 8 can apply an elastic support force to the slide 5, thereby ensuring the rotational stability of the turntable. The design of the two protective covers serves to protect the resistance adjustment components, while also making the product aesthetically pleasing. The detachable design facilitates the installation and replacement of accessories, improving the ease of operation of the product.

[0021] Furthermore, the slide 5 is provided with a first limiting groove 501, the connector of the ejector pin 6 is provided with a second limiting groove 602, and the connecting rod 9 is provided with a first connecting post 12 and a second connecting post 13. The two ends of the first connecting post 12 are movably connected to the first limiting groove 501, and the two ends of the second connecting post 13 are movably connected to the second limiting groove 602. This design facilitates the stable connection of the connecting rod 9 to the ejector pin 6 and the slide 5, allowing for stable rotation between them, thus improving the product's adjustment effect and exercise effectiveness.

[0022] Furthermore, the upper end of the slide 5 is provided with a first positioning groove 502 for one end of the adjusting member 4 to be inserted, and the lower end of the slide 5 is provided with a second positioning groove for one end of the elastic member 8 to be inserted. This design improves the operational accuracy of the adjusting member 4 on the slide 5 and the effective support of the elastic member 8 on the slide 5, thereby enhancing the product's stability in use.

[0023] Furthermore, the connecting seat 1 is provided with a limiting mounting groove 101 for the movement of the ejector pin 6, and a limiting notch 102 for the movement of the connecting rod 9 is formed on one side of the limiting mounting groove 101. The above design can improve the installation stability of the ejector pin 6, prevent problems such as the ejector pin 6 running off-center during frequent vibration use, thereby improving the stability of the product and the training effect.

[0024] Furthermore, the turntable includes a rotating ring 14 and two cover plates 15. The rotating base 2 has two mounting brackets for the rotation of the two cover plates 15. The two cover plates 15 are fixedly connected to the upper and lower sides of the rotating ring 14 by screws, and a resistance adjustment gap is formed between the outer wall of the rotating ring 15 and the inner wall of the rotating base 2. A handle 3 is disposed inside the rotating ring 14. The above design, including the mounting brackets, prevents the cover plates 15 from detaching from the rotating base 2. The handle 3 is provided for the user's hand grip. If necessary, a sliding washer can also be provided between the cover plates 15 and the rotating base 2 to avoid excessive friction between them, thereby improving the product's stability and the effectiveness of the exercise.

[0025] Furthermore, the damping component includes a friction plate mounting base 16 and a friction plate 17. The friction plate mounting base 16 is mounted on the inner wall of the rotating seat 2, and the friction plate 17 is disposed on the friction plate mounting base 16 and faces the outer wall of the turntable. One end of the ejector pin 6 passes through the rotating seat 2 and abuts against the friction plate mounting base 16. With the above design, the friction plate mounting base 16 can drive the friction plate 17 to self-reset after being compressed and deformed. At the same time, combined with the elastic support of the fixing rod 7 and the elastic element 8, the operation of the speed arm device is more stable.

[0026] Furthermore, the adjusting component 4 includes an adjusting knob 18 and a screw section. A fixing nut 19 is fitted onto the screw section. A mounting hole for fitting the fixing nut 19 is formed between the first protective cover 10 and the second protective cover 11, and the adjusting knob 18 is located outside the first protective cover 10 and the second protective cover 11. With this design, the adjusting knob 18 facilitates adjustment, and the fixing nut 19 is used to fix the position of the adjusting component 4, thereby improving the ease of operation and the stability of the product's performance.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
