[0021] The following reference Figures 1 to 5 The exercise device in the embodiments of this application is described.

[0022] The exercise device described in this application is a shoulder joint exercise device, designed for shoulder joint exercise or rehabilitation. Figures 1 to 3 As shown, an embodiment of the exercise device of this application includes a connecting rod 13, a first handle 11, a second handle 12, a first locking member 14, and a second locking member 15. The first handle 11 is bent for easy gripping and is retractable and rotatable at one end of the connecting rod 13. The first handle 11 can slide relative to or away from the connecting rod 13 and can also rotate relative to the connecting rod 13. The second handle 12 is bent and retractable and rotatable at the other end of the connecting rod 13. Similarly, the second handle 12 can slide relative to or away from the connecting rod 13 and can also rotate relative to the connecting rod 13. The first locking member 14 restricts the sliding and rotation of the first handle 11 relative to the connecting rod 13, and the second locking member 15 restricts the sliding and rotation of the second handle 12 relative to the connecting rod 13.

[0023] Before use, the first handle 11 and the connecting rod 13 are unlocked by the first locking member 14, and the second handle 12 and the connecting rod 13 are unlocked by the second locking member 15. This allows the first handle 11 and / or the second handle 12 to slide relative to the connecting rod 13, thereby adjusting the length of the exercise device to suit the user's needs. The first handle 11 and / or the second handle 12 are also rotated relative to the connecting rod 13 to adjust the grip direction, allowing the user to adjust the grip to achieve the optimal force angle for exercise or rehabilitation, thus improving the effectiveness of the exercise and significantly enhancing its practicality and applicability. When not in use, the exercise device can be slid closer to the connecting rod 13 by the first handle 11 and the second handle 12 to shorten its length, making it easy to store in a small suitcase or bag for convenient transport. When using it, the user holds the first handle 11 and the second handle 12 with both hands respectively, and then uses one hand to drive the other hand to move, thereby exercising the shoulder joint.

[0024] according to Figure 1 As shown, in one embodiment of this application, the connecting rod 13 is provided with a first connecting end 134 and a second connecting end 135. (Continuing to refer to...) Figure 2 The first connecting end 134 is provided with a first guide groove 1321, and the second connecting end 135 is provided with a second guide groove 1331. The first handle 11 includes a first guide rod 113 and a first grip portion 114. The first grip portion 114 is fixedly connected to the first guide rod 113. The first guide rod 113 is telescopically and rotatably installed in the first guide groove 1321. The first guide rod 113 can telescopically slide relative to the first guide groove 1321 and can also rotate relative to the first guide groove 1321, so that the first handle 11 is telescopically and rotatably installed at one end of the connecting rod 13. The second handle 12 includes a second guide rod 123 and a second grip portion 124. The second grip portion 124 is fixedly connected to the second guide rod 123. The second guide rod 123 is telescopically and rotatably installed in the second guide groove 1331. The second guide rod 123 can telescopically slide relative to the second guide groove 1331 and can also rotate relative to the second guide groove 1331, so that the second handle 12 is telescopically and rotatably installed at the other end of the connecting rod 13.

[0025] Before use, the distance between the first grip portion 114 and the second grip portion 124 can be adjusted by moving the first guide rod 113 and the second guide rod 123 closer to or further away from the connecting rod 13, thereby adjusting the usable length of the exercise device. Moving the first guide rod 113 and the second guide rod 123 further apart increases the usable length of the exercise device; moving them closer together decreases the usable length. The gripping direction of the exercise device can also be adjusted by rotating the first guide rod 113 and / or the second guide rod 123 relative to the connecting rod 13, thereby adjusting the relative angle between the first grip portion 114 and the second grip portion 124.

[0026] In some embodiments, see Figure 2 and Figure 3 The first grip 114 is detachably connected to the first guide rod 113, and similarly, the second grip 124 is detachably connected to the second guide rod 123, thereby further facilitating disassembly and storage, making it easy to carry, and also facilitating production and assembly. Specifically, the detachable connection can be achieved through a convex-concave fit, where the convex part and the concave part are interference-fitted.

[0027] according to Figure 3 As shown, in one embodiment of this application, the first guide rod 113 is provided with a first straight groove 111 and a plurality of first annular grooves 112. The first straight groove 111 is disposed on the outside of the first guide rod 113 and is disposed along the axial direction of the first guide rod 113. The plurality of first annular grooves 112 are circumferentially disposed on the outside of the first guide rod 113 and are spaced apart along the axial direction of the first guide rod 113. The first straight groove 111 communicates with the first annular grooves 112.

[0028] The second guide rod 123 is provided with a second straight groove 121 and a plurality of second annular grooves 122. The second straight groove 121 is disposed on the outside of the second guide rod 123 and is disposed along the axial direction of the second guide rod 123. The plurality of second annular grooves 122 are disposed circumferentially on the outside of the second guide rod 123 and are spaced apart along the axial direction of the second guide rod 123. The second straight groove 121 communicates with the second annular grooves 122.

[0029] according to Figures 1 to 3 As shown, in one embodiment of this application, a first locking member (not shown) is fixedly disposed on the inner side of the first guide groove 1321, and the first locking member (not shown) is slidably disposed in the first straight groove 111 or any first annular groove 112. One end of the first locking member (not shown) is fixedly connected to the inner side of the first guide groove 1321, and the other end is rubbed connected to the inner wall of the first straight groove 111 or any first annular groove 112.

[0030] When the length of the exercise device needs to be adjusted, force is applied to rotate the first handle 11 to overcome the frictional resistance between the first locking member (not shown) and the first guide rod, so that the first guide rod 113 rotates relative to the connecting rod 13, and the first locking member (not shown) slides into the first straight groove 111; then the first handle 11 is driven to slide relative to the connecting rod 13, so that the first locking member (not shown) slides relative to the first straight groove 111; after adjusting to a suitable length, the first handle 11 is rotated to make the first locking member (not shown) slide into the corresponding first annular groove 112, preventing the first handle 11 from sliding relative to the connecting rod 13, realizing the sliding lock of the first handle 11, and completing the adjustment of the length of the exercise device.

[0031] When it is necessary to adjust the grip direction of the exercise device, force is applied to rotate the first handle 11 to overcome the frictional resistance between the first locking member (not shown) and the first guide rod, so that the first guide rod 113 rotates relative to the connecting rod 13, and the first locking member (not shown) slides in the first annular groove to complete the angle adjustment of the grip direction of the exercise device.

[0032] The second locking member (not shown) is fixedly disposed inside the second guide groove 1331. The second locking member (not shown) is slidably disposed in the second straight groove 121 or any second annular groove 122. One end of the second locking member (not shown) is fixedly connected to the inner side of the second guide groove 1331, and the other end is rubbed connected to the inner wall of the second straight groove 121 or any second annular groove 122.

[0033] Similarly, when the length of the exercise device needs to be adjusted, force is applied to rotate the second handle 12 to overcome the frictional resistance between the second locking member (not shown) and the second guide rod, so that the second guide rod 123 rotates relative to the connecting rod 13, and the second locking member (not shown) slides into the second straight groove 121; then the second handle 12 is driven to slide relative to the connecting rod 13, so that the second locking member (not shown) slides relative to the second straight groove 121; after adjusting to the appropriate length, the second handle 12 is rotated to make the second locking member (not shown) slide into the corresponding second annular groove 122, preventing the second handle 12 from sliding relative to the connecting rod 13, thus achieving the sliding lock of the second handle 12 and completing the adjustment of the length of the exercise device.

[0034] When it is necessary to adjust the grip direction of the exercise device, force is applied to rotate the second handle 12 to overcome the frictional resistance between the second locking member (not shown) and the second guide rod, so that the second guide rod 123 rotates relative to the connecting rod 13, and the second locking member (not shown) slides in the second annular groove to complete the angle adjustment of the grip direction of the exercise device.

[0035] Both the first handle 11 and the second handle 12 can rotate 360° relative to the connecting rod 13, making it easier for the user to obtain the most suitable force angle for better exercise or rehabilitation treatment.

[0036] according to Figure 2 and Figure 3 As shown, in one embodiment of this application, the first connecting end 134 is provided with a first insertion hole 1322, the center of which coincides with the circle of the first annular groove 112. (Continue to see...) Figure 4 The first locking member 14 includes a first push plate 141 and a first slider 142. The first slider 142 is fixedly connected to the first push plate 141. The first push plate 141 is disposed on the outside of the first connecting end 134. The first slider 142 passes through the first insertion hole 1322 and is slidably disposed in the first straight groove 111 or any first annular groove 112. One end of the first slider 142 is fixedly connected to the inner side of the first locking member 14, and the other end is in frictional contact with the inner wall of the first straight groove 111 or any first annular groove 112.

[0037] See Figures 1 to 4 When the length of the exercise device needs to be adjusted, the frictional resistance between the first slider 142 and the first guide rod is overcome, and the first push plate 141 is pushed to make the first slider 142 slide in the first insertion hole 1322 and slide into the first straight groove 111; then the first handle 11 is driven to slide relative to the connecting rod 13 so that the first locking member 14 slides relative to the first straight groove 111; after adjusting to the appropriate length, the first push plate 141 is pushed back to make the first slider 142 slide into the corresponding first annular groove 112 to prevent the first handle 11 from sliding relative to the connecting rod 13, thereby achieving the sliding lock of the first handle 11 and completing the adjustment of the length of the exercise device.

[0038] When it is necessary to adjust the grip direction of the exercise device, force is applied to rotate the first handle 11 to overcome the frictional resistance between the first slider 142 and the first guide rod, so that the first guide rod 113 rotates relative to the connecting rod 13, and the first slider 142 slides in the first annular groove to complete the angle adjustment of the grip direction of the exercise device.

[0039] See Figures 1 to 4The second connecting end 135 is provided with a second insertion hole 1332, the center of which coincides with the center of the second annular groove 122. The structure of the second locking member 15 is the same as that of the first locking member 14. The second locking member 15 includes a second push plate (not shown) and a second slider (not shown). The second slider is fixedly connected to the second push plate, which is located on the outside of the second connecting end 135. The second slider passes through the second insertion hole 1332 and slides within the second straight groove 121 or any of the second annular grooves 122. One end of the second slider is fixedly connected to the inner side of the second locking member 15, and the other end is in frictional contact with the inner wall of the second straight groove 121 or any of the second annular grooves 122.

[0040] Similarly, when the length of the exercise device needs to be adjusted, the frictional resistance between the second slider and the second guide rod is overcome, and the second push plate is pushed to make the second slider slide in the second insertion hole 1332 and slide into the second straight groove 121; then the second handle 12 is driven to slide relative to the connecting rod 13 so that the second locking member 15 slides relative to the second straight groove 121; after adjusting to the appropriate length, the second push plate is pushed back to make the second slider slide into the corresponding second ring groove 122 to prevent the second handle 12 from sliding relative to the connecting rod 13, thereby achieving the sliding lock of the second handle 12 and completing the adjustment of the length of the exercise device.

[0041] When it is necessary to adjust the grip direction of the exercise device, force is applied to rotate the second handle 12 to overcome the frictional resistance between the second slider and the second guide rod, so that the second guide rod 123 rotates relative to the connecting rod 13, and the second slider slides in the second annular groove to complete the angle adjustment of the grip direction of the exercise device.

[0042] according to Figure 4 As shown, in one embodiment of this application, the first push plate 141 is provided with a first anti-detachment hook 143, and the first anti-detachment hook 143 is provided with a first hook portion (not shown in the figure). See also... Figure 2 The first anti-detachment hook 143 passes through the first insertion hole 1322 and hooks onto the inner wall of the first guide groove 1321, with the first hook portion abutting against the inner wall of the first guide groove 1321. The second push plate (not shown) is provided with a second anti-detachment hook (not shown), which has a second hook portion. The second anti-detachment hook passes through the second insertion hole 1332 and hooks onto the inner wall of the second guide groove 1331, with the second hook portion abutting against the inner wall of the second guide groove 1331. The provision of the first anti-detachment hook 143 and the second anti-detachment hook prevents the first locking member 14 and the second locking member 15 from disengaging from the connecting rod 13.

[0043] In existing technologies, exercise devices cannot calculate exercise time or remind users when they have reached the required exercise duration. Therefore, according to Figure 1 , Figure 2 and Figure 5 As shown, in one embodiment of this application, the connecting rod 13 is provided with a control circuit board 16, a switch button 17, and a time setting button 18. The switch button 17 is electrically connected to the control circuit board 16, and the time setting button 18 is electrically connected to the control circuit board 16. The control circuit board 16 includes a timing module and a buzzer module. The first handle 11 and / or the second handle 12 are provided with a timing start button 19 connected to the control circuit board 16.

[0044] When using the exercise device, after adjusting the length and grip angle to a suitable position, the user can activate the control circuit board 16 via the power button 17, and then set the exercise duration via the time setting button 18. Once the exercise duration is reached, the buzzer module will sound to remind the user that the set exercise time has ended. The user can also activate the timing module on the control circuit board 16 via the timer start button 19, and stop the timer by pressing the timer start button 19 again, thus calculating the exercise time and clearly understanding the specific duration of their exercise using the device.

[0045] The control circuit board 16 also includes a data recording module and a communication module. The data recording module can save exercise data and can also transmit exercise data to an APP on other devices such as mobile phones through the communication module, so as to facilitate the analysis of other parameters such as the user's posture, exercise duration, and number of exercises when using the exercise device.

[0046] In some embodiments, the control circuit board 16 is specifically configured as an MCU control board.

[0047] In some embodiments, the control circuit board 16 further includes an infrared receiving module, and the timing start button 19 is equipped with an infrared emitting module. After the timing start button 19 is pressed, the infrared emitting module of the timing start button 19 emits an infrared signal, and the infrared receiving module of the control circuit board 16 receives the infrared signal and drives the timing module to start timing.

[0048] In some embodiments, the exercise duration can be played back aloud via a buzzer module after the timer stops. In some embodiments, the exercise duration can also be transmitted to an app on other devices such as mobile phones via a communication module.

[0049] In some embodiments, the communication module may be configured as a Bluetooth communication module.

[0050] In some embodiments, a daily exercise period can also be set on the control circuit board 16, and the control circuit board 16 will remind the user to exercise during the preset period through a buzzer module.

[0051] In one embodiment of this application, see [link to embodiment]. Figures 1 to 3The first handle 11 and / or the second handle 12 are provided with a protrusion 20 at the bend, and the timing start button 19 is installed on the arc surface of the protrusion 20, so that the user can press the timing start button 19.

[0052] In one embodiment of this application, the exercise device further includes a battery module for supplying power to the control circuit board 16.

[0053] In some embodiments, the battery module includes a first battery assembly (not shown) and a first charging unit (not shown). See also Figure 1 , Figure 2 and Figure 5 The first battery assembly is disposed inside the connecting tube 131 and is used to supply power to the control circuit board 16; the first charging unit is disposed on the connecting tube 131, and the external power supply charges the battery assembly through the first charging unit. Specifically, the first charging unit is configured with a Type-C interface.

[0054] In some embodiments, see Figures 1 to 3 The battery module includes a second battery assembly 21 and a battery cover 22. A mounting slot 115 is provided on the first handle 11 and / or the second handle 12. The second battery assembly 21 is embedded in the mounting slot 115 and is electrically connected to a control circuit board 16 to supply power to the control circuit board 16. The battery cover 22 covers the opening of the mounting slot 115, thereby protecting the second battery assembly 21. The second battery assembly 21 can be replaced simply by opening the battery cover 22. In some embodiments, the battery cover 22 also provides a second charging section (not shown), through which the second battery assembly 21 can be charged.

The first guide tube 132 and the second guide tube 133 are detachably disposed at both ends of the connecting tube 131. By making the first guide tube 132, the connecting tube 131, and the second guide tube 133 detachable, the user can more easily disassemble the exercise device, thereby further facilitating its portability.

[0056] In some embodiments, see Figure 5The inner walls of the first guide tube 132 and the second guide tube 133 near the connecting tube 131 are provided with multiple slots 136 and at least one guide groove 137. The two ends of the connecting tube 131 are respectively provided with a corresponding number of third anti-detachment hooks 1311 and a corresponding number of guide blocks (not shown). During assembly, the guide blocks cooperate with the guide grooves 137 to achieve initial positioning connection between the first guide tube 132 and the second guide tube 133 and the connecting tube 131. The slots 136 cooperate with the third anti-detachment hooks 1311 to achieve detachable connection between the first guide tube 132 and the second guide tube 133 and the connecting tube 131. Specifically, the first guide tube 132 and the second guide tube 133 are respectively provided with four slots 136 and one guide groove 137, and the two ends of the connecting tube 131 are respectively provided with four third anti-detachment hooks 1311 and one guide block.
