[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0035] See Figures 1 to 8 As shown, an arm trainer with vibration function includes a shell 1, a gripping part 14 in the middle of the shell 1, and an annular track on the shell 1. The track is located on the outer periphery of the gripping part 14, and a counterweight component 2 is slidably mounted on the track. The movement of the shell 1 is controlled by the gripping part 14, and the counterweight component 2 can slide along the annular track. During use, the user can increase the training intensity by increasing the movement speed of the counterweight component 2. The annular track is designed to increase the movement radius of the counterweight component 2, which is beneficial to increasing the training intensity, reducing the rotation speed of the counterweight component 2 during exercise, and improving the safety of the arm trainer.
[0036] The outer shell 1 is equipped with a drive motor 3 and an eccentric block 31. The drive motor 3 can drive the eccentric block 31 to move and cause the outer shell 1 to vibrate. The arrangement of the drive motor 3 and the eccentric block 31 allows the outer shell 1 to vibrate during arm training, which is beneficial to promote blood circulation, relieve muscle fatigue, prolong training time, and improve training effect.
[0037] The outer shell 1 of this utility model includes an annular outer shell body 13, and a gripping part 14 is disposed in the outer shell body 13 and connected to both sides of the outer shell body 13. This structure is beneficial to reduce the weight of the arm trainer, reduce production costs, and facilitate the storage and transportation of the arm trainer. Preferably, a control groove 15 is formed between the two sides of the gripping part 14 and the outer shell body 13. The setting of the control groove 15 makes it easy for the user to flexibly grip the gripping part 14 and facilitates the user's use.
[0038] In this embodiment, the outer casing 1 is provided with a controller 5 for controlling the drive motor 3.
[0039] The gripping part 14 is provided with a mounting cavity 111, and the drive motor 3 and the eccentric block 31 are both located in the mounting cavity 111. This structure facilitates the drive motor 3 and the eccentric block 31 to drive the gripping part 14 to vibrate, thereby facilitating the arm trainer to drive the user's arm to vibrate, which is beneficial to promoting blood circulation and relieving muscle fatigue. In addition, this structure helps to ensure that the center of gravity of the outer shell 1 falls on the gripping part 14, making it easier for the user to control the arm trainer for exercise through the gripping part 14.
[0040] In this utility model, the output shaft of the drive motor 3 extends to both ends of the drive motor 3, and eccentric blocks 31 are detachably provided at both ends of the output shaft. The eccentric blocks 31 provided at both ends of the output shaft not only help to enhance the vibration effect of the housing 1, but also help to balance the gravity of the housing 1, making it convenient for users to use and control.
[0041] Preferably, the mounting cavity 111 is symmetrically provided with fixing slots 112 on both sides, and each fixing slot 112 is provided with a power supply 32 that is electrically connected to the drive motor 3. The fixing slots 112 symmetrically provided on both sides of the mounting cavity 111 and the power supply 32 provided in the fixing slots 112 are conducive to making the center of gravity of the outer shell 1 fall on the grip part 14, so that the user can control the arm trainer to exercise through the grip part 14.
[0042] In this embodiment, the outer shell 1 includes a detachably connected upper shell 11 and a lower shell 12. An annular groove 16 is formed between the upper shell 11 and the lower shell 12, and a mounting cavity 111 for mounting the drive motor 3 and the eccentric block 31 is formed. The detachably connected upper shell 11 and lower shell 12 facilitate the assembly and production of the outer shell 1, and facilitate the fixed installation of the drive motor 3 and the eccentric block 31.
[0043] The track section is an annular groove 16 with a constriction on its outer periphery. The counterweight assembly 2 includes a counterweight block 23 and a slide block 21 slidably connected to the annular groove 16. The slide block 21 passes through the constriction and enters the annular groove 16. A roller 214 that rotatably engages with the side wall of the annular groove 16 is mounted on the slide block 21. The annular groove 16 and the constriction facilitate the stable installation of the counterweight assembly 2 and prevent the counterweight assembly 2 from accidentally detaching from the outer shell 1 during use, which helps improve the safety of the arm trainer. The roller 214 helps reduce the friction experienced by the counterweight assembly 2 during use, allowing the counterweight assembly 2 to move flexibly on the outer shell 1, making it convenient for users to train with the arm trainer.
[0044] In this embodiment, both the upper shell 11 and the lower shell 12 are provided with grooves 161. When the upper shell 11 and the lower shell 12 are assembled, the grooves 161 on the upper shell 11 and the lower shell 12 combine to form the annular groove 16, and the sidewalls of the grooves 161 on the upper shell 11 and the lower shell 12 form the constriction.
[0045] The slide 21 is provided with a connecting part 212 that passes through the constriction. The connecting part 212 is provided with a supporting ball 215. The supporting ball 215 can abut against the side wall of the constriction and support the slide 21. The setting of the supporting ball 215 helps to reduce the friction between the slide 21 and the side wall of the constriction during use, and facilitates the flexible movement of the counterweight component 2 on the outer shell 1, making it convenient for users to use the arm trainer for training.
[0046] In this embodiment, the slide block 21 includes two detachably connected first housings 211. Each first housing 211 is provided with a connecting part 212, and each connecting part 212 is provided with a through ball groove 216. The supporting balls 215 are respectively inserted into the ball groove 216 on both sides and abut against the side wall of the constriction 17 through the ball groove 216.
[0047] In this invention, the counterweight 23 and the slide 21 are connected by a flexible rope 22, and the distance between the counterweight 23 and the slide 21 can be adjusted by the flexible rope 22. The flexible rope 22 facilitates the flexible installation of the counterweight 23 and the slide 21, and allows the user to adjust the distance between the counterweight 23 and the slide 21, thereby adjusting the movement radius of the counterweight assembly 2. This is beneficial for flexibly adjusting the training intensity and is convenient for the user. The slide 21 is provided with a connection hole 217 for connecting to the flexible rope 2.
[0048] The outer casing 1 is provided with a display screen 4 and a counting device 41. The display screen 4 can display the counting result of the counting device 41. The counterweight assembly 2 is provided with a detection part 213 corresponding to the counting device 41. The counting device 41 can detect the detection part 213, thereby counting the number of sliding revolutions of the counterweight assembly 2 on the circular track. The setting of the counting device 41 and the detection part 213 makes it easy for users to understand the training volume and facilitates users to plan their training program.
[0049] 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.
