Description

Technical Field

[0001] This utility model belongs to the field of arm strength training technology, and specifically relates to an arm strength training device. Background Technology

[0002] A forearm wrist flexor is a type of exercise device used to strengthen the forearm wrist flexor muscles. It is primarily used to train arm and chest muscles, and also to strengthen wrist muscles.

[0003] Traditional arm exercisers consist of handles attached to both ends of a spring. During use, the spring is bent by the handles to generate exercise force. Most arm exercisers on the market today include a V-shaped swing arm and use elastic elements or hydraulic cylinders for damping during movement, as illustrated in Chinese utility model patent application CN. A folding arm exerciser disclosed in 202222363549.X includes two fixed blocks arranged symmetrically on the left and right. Each fixed block has a groove at one end away from the other, and a crossbar is movably connected to each groove. A set of first springs is connected to the front end of each crossbar, and a handle is connected to the front end of each set of first springs. The two handles are rotatably connected to the two grooves respectively. Connecting blocks are provided at the front and rear ends of each fixed block, and the two connecting blocks are movably connected to the two fixed blocks via four rotating shafts. Several adjusting holes are provided at the upper middle part of the left fixed block and the upper right part of the right fixed block, with bolts installed in the adjusting holes. Through holes are provided at the upper right part of the left fixed block and the upper left part of the right fixed block, with a fixing component installed in each of the through holes.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0031] See Figures 1 to 6 As shown, an arm strength trainer includes two opposing swing arms 1 and an elastic element 3 for driving the two swing arms 1 to return to their original position. The middle of the swing arms 1 is rotatably connected by a hinge rod 2, and each swing arm 1 is provided with a first grip 11 and a second grip 12. The first grip 11 and the second grip 12 are respectively located on both sides of the hinge rod 2. Controlling the two first grips 11 on the two swing arms 1 to move closer together will cause the second grips 12 on the swing arms 1 to move away from each other. This arm strength trainer only includes two swing arms 1, an elastic element 3, and a hinge rod 2. It has a simple structure and is easy to assemble and manufacture. In addition, because the two swing arms 1 are opposite to each other in this structure, the two first grips 11 moving closer together will cause the second grips 12 on the swing arms 1 to move away from each other. During exercise, the first grips 11 and the second grips 12 move in opposite directions. Users can perform arm strength training by controlling the two first grips 11 to move closer together, and users can also perform chest expansion exercises by controlling the second grips 12 to move away from each other. Users can use it flexibly according to their needs, which is convenient for users to exercise flexibly and reduces the cost of purchasing fitness equipment.

[0032] The two swing arms 1 are not crossed in an X or V shape. In this embodiment, the two swing arms 1 extend to the other swing arm 1 to form a hinge protrusion 16. The hinge rod 2 passes through the hinge protrusion 16 and rotatably connects the two swing arms 1. The first grip 11 and the second grip 12 on the same swing arm 1 are located on the same side of the left and right sides of the hinge rod 2, and the first grip 11 and the second grip 12 on the same swing arm 1 are located on the upper and lower sides of the hinge rod 2, respectively.

[0033] The elastic element 3 is detachably mounted on the swing arm 1. Each swing arm 1 has several positioning parts 15 for mounting the elastic element 3. These positioning parts 15 are sequentially located away from the hinge axis. By controlling the installation of the elastic element 3 in different positioning parts 15, the damping during the movement of the two swing arms 1 can be adjusted. Because the positioning parts 15 are sequentially located away from the hinge axis, the user can adjust the damping of the arm exerciser by installing the elastic element 3 in different positioning parts 15. The user can also install elastic elements 3 of different specifications on the positioning parts 15 to adjust the damping of the arm exerciser, allowing for flexible adjustment of the arm exerciser's damping as needed. This facilitates flexible adjustment of the arm exerciser and allows different users to exercise using the same arm exerciser.

[0034] In this utility model, only one elastic element 3 can be installed in the plurality of positioning parts 15, and elastic elements 3 can be installed in the plurality of positioning parts 15 respectively. This structure is beneficial to improving the maximum damping of the arm strength trainer and making it convenient for different users to use the arm strength trainer.

[0035] The swing arm 1 is provided with a mounting protrusion 14, and a positioning part 15 is provided on the side of the mounting protrusion 14. The elastic element 3 is a ring-shaped elastic rope. The elastic rope is sleeved on the outer periphery of the mounting protrusion 14 on the swing arm 1 and cooperates with the positioning part 15. The mounting protrusion 14 and the ring-shaped elastic rope facilitate the disassembly and installation of the elastic element 3. In addition, the elastic element 3 is stably installed in this structure, which avoids the elastic element 3 from falling off accidentally during use and facilitates the use of the arm strength device.

[0036] Preferably, the swing arm 1 is provided with a protective groove 13, and the positioning part 15 and the mounting protrusion 14 are both provided on the side of the protective groove 13. The setting of the protective groove 13 helps to avoid or reduce the occurrence of other objects causing the elastic rope to detach from the positioning part 15, and avoids the installation position of the elastic rope changing or the elastic rope accidentally detaching during use, making it convenient for users to use. In this embodiment, the positioning part 15 is a groove, and the positioning part 15 is respectively provided on the side of the two positioning protrusions that are far away from each other.

[0037] The mounting protrusion 14 described in this utility model has a clearance part 18 on its side. The clearance part 18 can be used to guide the deformation of the elastic rope and to adjust or remove the installation of the elastic rope. The clearance part 18 makes it convenient for users to adjust or remove the elastic rope, making it convenient for users to use the arm strength exerciser.

[0038] Both swing arms 1 are provided with hinge holes 17 that are adapted to the hinge rod 2. The hinge rod 2 includes a hinge part 22. One end of the hinge part 22 is provided with a limiting part 21, and the other end of the hinge part 22 is provided with a hook part 23. The hook part 23 can pass through the hinge holes 17 on the two swing arms 1 and rotatably connect the two swing arms 1 through the hinge part 22. In this structure, since the hinge rod 2 includes the limiting part 21, the hinge part 22 and the hook part 23, the two swing arms 1 can be connected by the hinge rod 2 alone, which helps to simplify the structure of the arm strength device, facilitates the assembly and disassembly of the arm strength device, and facilitates the production and maintenance of the arm strength device.

[0039] In this embodiment, the end of the hook portion 23 is provided with an inclined driving surface 24. The end of the hinge hole 17 can abut against the driving surface 24 and drive the hook portion 23 to deform, so that the hook portion 23 can pass over the hinge hole 17. The driving surface 24 facilitates the deformation and displacement of the hook portion 23, facilitates the quick installation of the hinge rod 2, and facilitates the assembly and production of the arm strength device.

[0040] In this invention, both swing arms 1 are provided with positioning walls 19, which are located on one side of the hinge rod 2. The elastic element 3 drives the two swing arms 1 to reset and makes the positioning walls 19 on the two swing arms 1 abut against each other, thereby limiting the maximum distance between the two first grips 11 and the minimum distance between the two second grips 12. The positioning walls 19 can limit the maximum distance between the two first grips 11 and the minimum distance between the two second grips 12, which can prevent the two second grips 12 from colliding with each other during use, prevent the user's swing arms 1 from pinching the user, and make it convenient for the user to use.

[0041] A counting device is provided on one side of the positioning wall 19 of one swing arm 1, and a sensing part corresponding to the technical device is provided on the other swing arm 1; the two swing arms 1 are controlled to reciprocate, the counting device can sense the sensing part and count the movement of the swing arms 1. The setting of the counting device and the sensing part makes it convenient for users to understand the exercise process in real time and facilitates users to train according to the plan.

[0042] In this embodiment, the counting device includes a display screen and sensors. The sensors can be Hall elements, infrared sensors, or contact switches. The sensing part is a magnetic metal or the like corresponding to each sensor. This structure is widely used in fitness equipment. Therefore, although it is not specifically shown in the specification and accompanying drawings, those skilled in the art can implement this technical solution according to their own needs.

[0043] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
