Description

Technical Field

[0001] This utility model relates to the field of rehabilitation equipment technology, specifically to a counting grip strength training device. Background Technology

[0002] Clinically, patients are often encouraged to clench their fists or use plastic grip balls to exercise their arms after surgery to prevent mechanical phlebitis after PICC surgery. To standardize training and record the number of times the ball is gripped each time, patent number "CN216877765U" describes a grip ball with counting function. The grip ball body includes an elastic ball, an air inlet check valve, and an exhaust check valve. The elastic ball has a gas chamber, an air inlet, and an exhaust outlet. The air inlet check valve is installed inside the air inlet, and the exhaust check valve is installed inside the exhaust outlet. A counter is also included. The grip ball body includes a connecting sleeve installed inside the exhaust outlet and located outside the exhaust check valve. The elastic ball has a bypass hole extending from the surface of the grip ball body to the exhaust outlet. The intersection of the bypass hole and the exhaust outlet is located between the connecting sleeve and the exhaust check valve. The exhaust check valve includes a valve core and a pressing rod connected to the valve core. The counter includes a push-button switch and a counting device connected to the connecting sleeve. When the exhaust check valve is opened, the valve core moves outward, causing the pressing rod to press the push-button switch. The counting device records and displays the number of times the push-button switch is pressed.

[0003] In the aforementioned patent, the counting device can display the number of times each ball-gripping training is performed, but the following problems still exist: depending on the severity of the condition and individual physical condition, it is best to use different forces to grip the ball for training, and as the condition recovers, it is also necessary to gradually change the gripping force. However, in the aforementioned patent, the force required to crush the gripping ball does not change, thus failing to meet the aforementioned requirements. Utility Model Content

[0004] To address the shortcomings of the existing technology, this invention proposes a counting grip strength training device.

[0005] To achieve the above-mentioned technical effects, the present invention adopts the following solution:

[0006] A grip strength counting training device, comprising:

[0007] The rubber ball itself,

[0008] An elastic support member is provided inside the rubber ball body to support the rubber ball body.

[0009] A one-way valve, wherein the one-way valve is disposed on the rubber ball body and the conduction direction is inward;

[0010] A connecting rod is sealed to the rubber ball body. One end of the connecting rod extends into the rubber ball body and connects to the elastic support, while the other end extends out of the rubber ball body.

[0011] The functional box is fixedly connected to the outer end of the connecting rod. The functional box has an air outlet chamber inside and an air outlet hole communicating with the air outlet chamber on the outer wall of the functional box. The inner end of the connecting rod has an exhaust port. The exhaust port and the air outlet chamber are connected through a venting channel provided in the connecting rod. A blocking block for blocking the venting channel is attached to the inner wall of the air outlet chamber. The blocking block is pressed against the inner wall of the air outlet chamber by a second pressure spring. The length of the second pressure spring is adjusted by an adjustment structure.

[0012] An infrared sensor counter is connected to the functional box and configured to cooperate with the blocking block.

[0013] In a preferred embodiment, the elastic support member includes an inner skeleton located at the center of the rubber ball body, and the inner skeleton is connected to the inner wall of the rubber ball body by a plurality of uniformly distributed first pressure springs.

[0014] In a preferred embodiment, the adjustment structure includes a push plate, a push rod, a slider, and an adjustment bolt. The push plate is located within the air outlet chamber and on the side of the sealing block away from the air passage. A second pressure spring connects the push plate and the sealing block. The functional box also includes an adjustment chamber, which is connected to the air outlet chamber via a guide sliding hole. The push rod is slidably disposed within the guide sliding hole. One end of the push rod is fixedly connected to the push plate, and the other end extends into the adjustment chamber. The sliding direction of the push rod is parallel to the elastic force direction of the second pressure spring. The slider is slidably disposed within the adjustment chamber, and the sliding direction of the slider is perpendicular to the sliding direction of the push rod. The adjustment bolt is rotatably mounted on the functional box, and its inner end extends into the adjustment chamber and is screwed onto the slider. The slider has an inclined surface corresponding to the push rod, and the other end of the push rod slides against the inclined surface of the slider.

[0015] In a preferred embodiment, the infrared sensor counter includes a counting display body disposed at the outer end of the function box, and a transmitter and a receiver disposed on the inner wall of the air outlet cavity. The transmitter and the receiver are respectively located at both ends of the sealing block and are disposed opposite to each other. Both the transmitter and the receiver are electrically connected to the counting display body.

[0016] In a preferred embodiment, the sealing block has a protruding piston portion that can be slidably embedded into the ventilation channel, and the piston portion matches the ventilation channel.

[0017] In a preferred embodiment, the air outlet chamber is provided with at least two guide rods, the two ends of which are respectively fixed on the inner walls of opposite sides of the air outlet chamber, and the sealing block is slidably installed on the at least two guide rods.

[0018] Compared with existing technologies, the beneficial effects are:

[0019] This invention features a simple structure and convenient use. By firmly squeezing the rubber ball, the body is compressed, forcing the gas inside into the vent through the exhaust port. The pressure on the gas in the vent pushes the sealing block, opening the connection between the vent and the outlet chamber. The gas then enters the outlet chamber and exits through the outlet. After the sealing block is pushed, it moves, causing the infrared sensor counter to count. When the rubber ball is released, the sealing block continues to block the vent under the force of the second pressure spring. The rubber ball then expands again under the elastic force of the elastic support, drawing air into the body through the one-way valve. In this invention, by adjusting the length of the second pressure spring, the pressure required to compress the sealing block is changed, requiring different forces to squeeze the rubber ball to create different pressures in the gas inside the vent to open the sealing block. This allows for training the user to use different grip strengths to improve grip strength. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] A grip strength counting training device includes: a rubber ball body 1, an elastic support, a one-way valve 4, a connecting rod 5, a function box 8, and an infrared sensor counter.

[0025] The rubber ball body 1 is a prior art material, which is a round or elliptical sphere made of rubber.

[0026] The elastic support member is disposed inside the rubber ball body 1 to expand the rubber ball body 1. After the rubber ball body 1 is crushed, it recovers its expansion through the elastic force of the elastic support member. Specifically, the elastic support member includes an inner frame 2 disposed at the center of the rubber ball body 1. Both ends of the inner frame 2 are fixedly connected to the inner wall of the rubber ball body 1. The inner frame 2 and the inner wall of the rubber ball body 1 are connected by a plurality of evenly distributed first pressure springs 3.

[0027] The one-way valve 4 is located on the rubber ball body 1 and is positioned with the conduction direction facing inward. The one-way valve 4 is existing technology, and air can only enter the rubber ball body 1 from the outside through the one-way valve 4, but cannot enter the rubber ball body 1 from the inside through the one-way valve 4.

[0028] The connecting rod 5 is sealed to the rubber ball body 1. One end of the connecting rod 5 extends into the rubber ball body 1 and is connected to the elastic support member, specifically, it is fixedly connected to the inner frame 2. The other end of the connecting rod 5 extends out of the rubber ball body 1.

[0029] The functional box 8 is fixedly connected to the outer end of the connecting rod 5. The functional box 8 is provided with an air outlet chamber 9. The outer wall of the functional box 8 is provided with an air outlet hole 10 that communicates with the air outlet chamber 9. The inner end of the connecting rod 5 is provided with an exhaust port 6. The exhaust port 6 and the air outlet chamber 9 are connected through a ventilation channel 7 provided in the connecting rod 5. A blocking block 11 for blocking the ventilation channel 7 is attached to the inner wall of the air outlet chamber 9. The blocking block 11 is pressed against the inner wall of the air outlet chamber 9 by a second pressure spring 19. The length of the second pressure spring 19 is adjusted by an adjustment structure. After the length of the second pressure spring 19 is changed, the pressure pressing the blocking block 11 can be adjusted.

[0030] Specifically, the adjustment structure includes a push plate 18, a push rod 17, a slider 14, and an adjusting bolt 16. The push plate 18 is located inside the air outlet chamber 9 and on the side of the blocking block 11 away from the air passage 7. The second pressure spring 19 is connected between the push plate 18 and the blocking block 11. The push plate 18 presses the second pressure spring 19 along its length, thereby pressing the blocking block 11 against the inner wall of the air outlet chamber 9 by the elastic force of the second pressure spring 19. The functional box 8 also has an adjustment chamber 13, which is connected to the air outlet chamber 9 through a guide sliding hole. The push rod 17 is slidably disposed in the guide sliding hole. One end of the push rod 17 is fixedly connected to the push plate 18, and the other end of the push rod 17 extends into the adjustment hole. Inside the cavity 13, the sliding direction of the push rod 17 is parallel to the elastic force direction of the second pressure spring 19. The slider 14 is matched and slides inside the adjustment cavity 13. The sliding direction of the slider 14 is perpendicular to the sliding direction of the push rod 17. The adjusting bolt 16 is rotatably mounted on the function box 8, and the inner end of the adjusting bolt 16 extends into the adjustment cavity 13 and is screwed into the slider 14. The screw head of the adjusting bolt 16 is located on the outer wall of the function box 8, and the screw of the adjusting bolt 16 extends into the adjustment cavity 13. The slider 14 has a screw hole that matches the screw of the adjusting bolt 16, so that the screw of the adjusting bolt 16 is inserted into the screw hole. The slider 14 has an inclined surface corresponding to the push rod 17, and the other end of the push rod 17 slides against the inclined surface of the slider 14.

[0031] An infrared sensor counter, employing existing technology, is connected to the functional box 8 and configured to cooperate with the sealing block 11. Specifically, the infrared sensor counter includes a counting display body 15 located at the outer end of the functional box 8, and a transmitter 21 and a receiver 22 located on the inner wall of the air outlet chamber 9. The transmitter 21 and receiver 22 are located at opposite ends of the sealing block 11. The infrared pulse path between the transmitter 21 and receiver 22 is positioned close to the sealing block 11 and avoids the position of the second pressure spring. If the second pressure spring is connected to the middle of the sealing block, the transmitter and receiver are positioned close to the edge of the sealing block. Both the transmitter 21 and receiver 22 are electrically connected to the counting display body 15. The counting display body 15 contains a battery and has a display screen showing the number of times the counter has been used, as well as a reset button.

[0032] Furthermore, the sealing block 11 has a protruding piston portion 12 that can be slidably embedded into the ventilation channel 7. The piston portion 12 matches the ventilation channel 7. With the setting of the piston portion 12, when the gas in the ventilation channel 7 pushes the sealing block 11 open, the sealing block 11 has a longer stroke, thereby ensuring that the sealing block 11 can move between the transmitter end 21 and the receiver end 22 of the infrared sensor counter when it is opened.

[0033] Furthermore, the air outlet chamber 9 is provided with at least two guide rods 20. The length of the guide rods 20 is parallel to the direction of movement when the sealing block 11 is pushed open. The two ends of the guide rods 20 are respectively fixed on the inner walls of opposite sides of the air outlet chamber 9. The sealing block 11 is slidably mounted on the at least two guide rods 20, and the guide rods 20 support and guide the sealing block 11.

[0034] During grip strength training, the rubber ball body 1 is squeezed tightly to deform it, thereby forcing the gas inside the rubber ball body 1 into the ventilation channel 7 through the exhaust port 6. The compressed gas in the ventilation channel 7 pushes the sealing block 11, thereby opening the connection between the ventilation channel 7 and the air outlet 9. The gas in the ventilation channel 7 enters the air outlet 9 and is discharged from the air outlet 10. After the sealing block 11 is pushed, it moves between the receiving end 22 and the transmitting end 21 of the infrared sensor counter, blocking the path of the infrared pulse from the transmitting end 21 to the receiving end 22. Thus, the infrared sensor counter is activated once. After the rubber ball body 1 is released, the sealing block 11 continues to block the ventilation channel 7 under the elastic force of the second pressure spring 19. The rubber ball body 1 recovers its expansion under the elastic force of the elastic support and draws air into the rubber ball body 1 through the one-way valve 4.

[0035] When grip strength needs adjustment, the screw head of the adjusting bolt 16 is turned, causing the screw of the adjusting bolt 16 to rotate. This causes the slider 14 to slide within the adjusting cavity 13. Since one end of the push rod 17 abuts against the inclined surface of the slider 14, the inclined surface can move the push rod 17, thereby adjusting the position of the push plate 18 and changing the length of the second pressure spring 19. After the pressure applied to the sealing block 11 by the second pressure spring 19 changes, the pressure required for the gas in the vent 7 to break through the sealing block 11 also changes, resulting in a different grip strength applied to the rubber ball body 1, thus adjusting the grip strength during training.
