Description

Technical Field

[0001] The utility model relates to the technical field of grip strength balls, in particular to a new type of counting grip strength ball. Background Art

[0002] Peripherally inserted central catheter (PICC) refers to a catheter inserted through a peripheral vein (cephalic vein, median cubital vein, basilic vein), with its end located in the superior vena cava or subclavian vein. Due to its long indwelling time, not easy to fall off, and able to protect the patient's blood vessels to safely inject irritating drugs, it has been widely used in clinical practice. However, PICC is prone to cause complications such as limb swelling, phlebitis, and venous thrombosis. Clinically, patients are mostly encouraged to use grip strength balls for arm exercises to prevent the occurrence of such complications.

[0003] From the grip strength counting training ball with the Chinese publication number CN213192361U, it can be seen that for this grip strength counting training ball, by gripping the sphere of the grip strength counting training ball, the sphere presses the counting dial to slide downward, and the counting rod at the bottom end of the counting dial transmits the downward force to the mechanical counter, and the mechanical counter makes the number at the right end of the counting display jump once to complete a count. Through the rabbit head-shaped pattern provided on the front of the sphere, the appearance of the grip strength counting training ball is made more beautiful. Through the sphere made of elastic rubber material, the grip strength counting training ball can be more comfortable to use. Through a layer of glass provided on the surface of the counting display, the counting display is better protected. Through the four-digit counting display, the counting display can more intuitively show the amount of exercise. Through the counting dial that can slide up and down inside the counting cavity, the sphere will not interfere with the counting of the counting dial.

[0004] However, through actual operation, it can be known that this type of grip strength ball cannot give the user grip force feedback. During the user's use process, it may cause the user's grip force to be insufficient, and the lack of obvious grip force feedback on the hand makes the user's use effect poor.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 , a new type of counting grip ball, including a sphere 1, gaskets 2 are laid on both the upper and lower outer walls of the sphere 1, the number of gaskets 2 is eight, four of the eight gaskets 2 are in a group and are respectively located above and below the sphere 1, and the spacing between adjacent ones of each group of four gaskets 2 is adapted to the spacing between four fingers. A display screen 3 is inlaid on the outer side of the front surface of the sphere 1.

[0025] According to Figure 1-2 As shown, a counter 9 is fixedly connected to the back of the display screen 3 inside the sphere 1. The inside of the sphere 1 is filled with a fixing base 10. An inner sphere 6 is arranged inside the fixing base 10. The number of the fixing bases 10 is two groups. The two groups of fixing bases 10 are located on both sides of the inner sphere 6 and are fixedly connected to the two inner spheres 6. Memory sponges are filled between the inner sphere 6 and the inner wall of the sphere 1. The inside of the inner sphere 6 is designed to be hollow. A pressing plate 4 is arranged inside the sphere 1. A connecting rod 7 is fixedly connected to the middle of the pressing plate 4. A counting dial 8 is arranged at the other end of the connecting rod 7. A spring 5 is fixedly connected to one side of the pressing plate 4.

[0026] According to Figure 2-3 As shown, connecting seats 13 are fixedly connected to both sides of the inner wall of the inner sphere 6. A plug rod 11 is arranged at the bottom of the pressing plate 4. The connecting rod 7 and the plug rod 11 are located in the same vertical plane. The connecting rod 7 is directly in front of the plug rod 11. A control block 12 is fixedly connected to one end of the plug rod 11.

[0027] According to Figure 1-4 As shown, a fixing rod 14 is fixedly connected to one end of the connecting seat 13. A resistance sleeve 17 is arranged on the outside of the fixing rod 14. A feedback ball 16 is slidably connected to the outside of the resistance sleeve 17. A reset spring 15 is fixedly connected to one side of the feedback ball 16. A collision ball 18 is slidably connected to the outside of the fixing rod 14. A connecting rod 19 is fixedly connected to the side wall of the collision ball 18. A push plate 20 is fixedly connected to the other end of the connecting rod 19. A connecting spring 21 is fixedly connected to one side of the push plate 20. The number of the push plates 20 is two. The two push plates 20 are symmetrically distributed with the vertical center line of the connecting spring 21 as the center. The two push plates 20 are respectively fixedly connected to both ends of the connecting spring 21. The two push plates 20 are slidably connected to the outer wall of the fixing rod 14. Each push plate 20 is fixedly connected to one side of the collision ball 18 through two connecting rods 19. The control block 12 is located on the opposite side of the two push plates 20.

[0028] During use, through the settings of the counter 9 and the counting dial 8, the function of counting the grip strength ball can be achieved through the counter 9, and the actual numbers can be displayed on the display screen 3 through the display screen 3 for the user to use, facilitating the user to clearly understand the intensity of their daily exercise. Through the settings of structures such as the feedback ball 16 and the impact ball 18, during the use process by the user, the impact ball 18 can impact the feedback ball 16. The vibration feedback to the sphere 1 is generated by the vibration caused by the impact on the feedback ball 16 in cooperation with the return spring 15. The grip force feedback is conveyed to the user's hand through the vibration to ensure that the user can clearly know the grip force situation and avoid the situation of traditional grip strength balls where the required force for grip is relatively small and the exercise intensity for the user's hand is poor. Among them, by the user placing the four fingers corresponding to the gasket 2, the friction between the hand and the sphere 1 is increased to ensure that it is more convenient for the user to apply force. When pressing the sphere 1, the top of the sphere 1 is recessed and drives the pressure plate 4 to squeeze the four springs 5, and at the same time drives the connecting rod 7 to move downward until the connecting rod 7 drives the counting dial 8 and the counter 9 to achieve one count. Through the connection between the counter 9 and the display screen 3, one count is displayed on the inner screen of the display screen 3, thus realizing the function of counting the grip strength ball. During the process of the pressure plate 4 squeezing the spring 5 and driving the connecting rod 7 to move, the plug rod 11 is driven to move downward until the control block 12 at the bottom of the plug rod 11 is located on the opposite side of the two push plates 20 and pushes the push plates 20 to both sides, while stretching the connecting spring 21. The movement of the push plates 20 drives the impact ball 18 to slide on the outer wall of the fixed rod 14 through the connecting rod 19 until the impact ball 18 impacts the feedback ball 16, causing the feedback ball 16 to compress the return spring 15. At this time, the pressing effect of the grip strength ball is completed. After no longer pressing the grip strength ball, as the connecting spring 21 returns, the impact ball 18 moves away from the feedback ball 16. At this time, the return of the return spring 15 pushes the feedback ball 16 to move on the outer wall of the fixed rod 14. At the same time, due to the characteristics of the return spring 15, the feedback ball 16 vibrates. In order to avoid a large vibration frequency, through the setting of the resistance sleeve 17, the sliding friction between the feedback ball 16 and the fixed rod 14 is increased, reducing the vibration amplitude of the feedback ball 16, ensuring that the user obtains the grip force feedback while avoiding discomfort caused to the user's hand exercise due to too high a vibration frequency. At the same time, as the finger cancels the pressing on the sphere 1, several springs 5 push the pressure plate 4 to move during the return process, and the memory sponge returns, causing the sphere 1 to return to its original state.

[0029] In summary, for the new type of counting grip ball, through the settings of the counter 9 and the counting paddle 8, the function of counting the grip ball can be realized through the counter 9, and the actual numbers can be displayed on the display screen 3 through the display screen 3 for the user to use, facilitating the user to clearly understand the intensity of their daily exercise. Through the settings of structures such as the feedback ball 16 and the impact ball 18, during the use process by the user, the impact ball 18 can impact the feedback ball 16. The impact received by the feedback ball 16 cooperates with the vibration generated by the return spring 15 to produce vibration feedback on the ball 1, and the vibration conveys grip feedback to the user's hand, ensuring that the user can clearly know the grip situation and avoiding the situation where the traditional grip ball requires less force for gripping and has a poor exercise intensity on the user's hand.
