Abstract
Description
Technical Field
[0001] This utility model relates to the field of sports equipment technology, specifically to a speed arm device. Background Technology
[0002] Currently, the arm speed machine has become a common tool for fitness enthusiasts to train their arms, wrists, and chest muscles. It has the advantages of small size and easy operation. However, during use, only the handle located inside the figure-eight ring can rotate. The figure-eight ring itself is a fixed structure, which restricts the arm speed machine in the three-dimensional training space and results in unsatisfactory training effects. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a fast arm device.
[0004] The technical solution of this utility model is as follows:
[0005] This utility model provides a fast arm device, including a bracket, which is provided with two angle adjustment rings. The peripheral part of the angle adjustment ring is connected to the bracket through a rotating shaft. The angle adjustment ring is rotatably connected to a rotating ring concentric with it. The angle adjustment ring is also provided with a resistance adjustment structure connected to the rotating ring. The resistance adjustment structure can adjust the resistance of the rotating ring relative to the angle adjustment ring. The inner ring of the rotating ring is provided with a handle.
[0006] Furthermore, the resistance adjustment structure includes a drive component disposed on the angle adjustment ring. The inner end of the drive component is the drive end, which is connected to a friction block. The friction block abuts against the rotating ring, and the drive component adjusts the squeezing force of the friction block on the rotating ring.
[0007] Furthermore, the center line of the rotating shaft is set radially along the angle adjustment ring.
[0008] Furthermore, the swivel ring is installed on the inner ring of the angle adjustment ring.
[0009] Furthermore, the rotating shaft has a hollow structure, and the driving component is a lead screw that passes through the rotating shaft. The outer end of the lead screw passes through the bracket and is rotatably connected to the bracket.
[0010] Furthermore, the outer end of the lead screw is threadedly connected to the bracket, and the friction block is fixedly installed on the inner end of the lead screw.
[0011] Furthermore, the outer end of the lead screw is only rotatably engaged with the bracket, the friction block is threadedly engaged with the inner end of the lead screw, and the friction block is slidably installed inside the angle adjustment ring through a guide structure.
[0012] Furthermore, a knob is fixedly installed at the outer end of the lead screw.
[0013] Furthermore, the inner ring of the angle adjustment ring is equipped with several rollers that cooperate with the outer ring of the rotating ring.
[0014] Furthermore, annular side plates are fixedly installed on both sides of the swivel, and the two side plates cover the angle adjustment ring.
[0015] The beneficial effects achieved by this utility model are as follows:
[0016] When using this invention, the user grasps the two handles with both hands, suspending the device in front of their chest. By controlling their arms, the user makes their hands circle each other in front of their chest. This requires overcoming the resistance of the rotating rings, thus exercising arm strength and performing strength training. Adjusting the distance between the two hands in the left and right directions in front of the chest during the circling process will adjust the angle of the angle adjustment ring relative to the support. This does not affect the arm training during the circling motion of the hands. It enables the hands to move relative to each other in a three-dimensional space outside the same plane. The exercise movements can be flexible and varied in three-dimensional space, improving the training effect and enjoyment. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection 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 application based on the specific circumstances.
[0023] like Figures 1-3 As shown, this utility model provides a fast arm device, including a bracket 1. Angle adjustment rings 2 are provided at both ends of the bracket. The peripheral part of the angle adjustment ring 2 is connected to the bracket 1 through a rotating shaft 3. The center line of the rotating shaft 3 is preferably arranged along the radial direction of the angle adjustment ring 2. The angle adjustment ring 2 is rotatably connected to a rotating ring 4 concentric with it. The rotating ring 4 is preferably installed in the inner ring of the angle adjustment ring 2, or it can be installed on one side of the angle adjustment ring 2. The angle adjustment ring is also provided with a resistance adjustment structure connected to the rotating ring 4. The resistance adjustment structure can adjust the resistance of the rotating ring 4 relative to the angle adjustment ring. A handle 5 is provided in the inner ring of the rotating ring.
[0024] In one embodiment, the resistance adjustment structure includes a drive component disposed on the angle adjustment ring. The drive component is preferably a lead screw 6. The rotating shaft 3 is a hollow structure. The lead screw 6 passes through the rotating shaft 3. The outer end of the lead screw 6 passes through the bracket 1 and is rotatably connected to it. The inner end of the lead screw 6 is the drive end and is located inside the angle adjustment ring. The drive end is connected to a friction block 7. The friction block 7 abuts against the rotating ring 4. By rotating the lead screw 6, the squeezing force of the friction block on the rotating ring can be adjusted, thereby adjusting the resistance to the rotation of the rotating ring. Of course, the drive component can also be directly rotatably mounted on the angle adjustment ring. For example, the lead screw is still selected and directly installed inside the angle adjustment ring by thread installation. By rotating the lead screw, the squeezing force of the friction block on the rotating ring can also be adjusted. Other drive component configuration methods can also be set.
[0025] The outer end of the lead screw 6 is preferably threaded to the bracket, and the friction block is fixedly installed on the inner end of the lead screw 6. The inner end of the lead screw is located in the inner ring of the angle adjustment ring. The pressure of the friction block on the rotating ring can be directly adjusted by rotating the lead screw.
[0026] The outer end of the lead screw can also be rotated only with the bracket. When the lead screw rotates, it only rotates relative to the bracket without moving along its axial direction. The friction block 7 is threadedly engaged with the inner end of the lead screw. The friction block 7 is slidably installed inside the angle adjustment ring through the guide structure. When the lead screw is rotated, it can drive the friction block to move along the axial direction of the lead screw, thereby adjusting the squeezing force of the friction block on the rotating ring.
[0027] A knob 8 is fixedly installed at the outer end of the lead screw, which allows for easier and less strenuous rotation of the lead screw.
[0028] The rotating ring is located on the inner ring of the angle adjustment ring. Several rollers 9 are set on the inner ring of the angle adjustment ring to cooperate with the outer ring of the rotating ring. The design of the rollers allows the rotating ring to rotate more smoothly.
[0029] Both sides of the rotating ring are fixedly equipped with ring-shaped side plates 10. The two side plates cover the angle adjustment ring. This design can prevent the angle adjustment ring from touching the user's arms or other parts during use, thus avoiding skin abrasions.
[0030] The bracket is X-shaped and has four ends. Each of the four ends of the bracket is connected to a corresponding angle adjustment ring via a rotating shaft, and each rotating shaft is equipped with a lead screw.
[0031] The working principle is as follows: the user grasps the two handles with both hands, suspending the device in front of their chest. By controlling their arms, the user makes their hands rotate in front of their chest. This requires overcoming the resistance of the rotating rings, thus exercising arm strength and performing strength training. Adjusting the distance between the two hands in front of the chest during the rotation will adjust the angle of the rings relative to the support. This does not affect the arm training during the circling motion, allowing the hands to move in a three-dimensional space outside the same plane. The exercise movements can be flexible and varied in three-dimensional space, improving the training effect and enjoyment.
[0032] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
