Description

Technical Field

[0001] This invention relates to the field of judo training technology, specifically to a finger training device for judo athletes. Background Technology

[0002] Judo athletes train their fingers primarily because grip technique is one of the core elements of judo combat. In matches, the fingers frequently perform high-intensity movements such as gripping, twisting, and pulling on the opponent's uniform. Long-term training significantly improves finger joint strength, endurance, and flexibility, ensuring grip stability and reducing the risk of sports injuries such as dislocations and tendinitis. It also enhances the ability to control the opponent during combat, providing a foundation for the execution of throwing and holding techniques. Therefore, judo athletes need to be equipped with finger training devices for finger training.

[0003] A finger training device for judo athletes, disclosed in Chinese Patent Publication No. CN113663294B, aims to enhance the finger strength of athletes by setting a sealing plug and a stirring device on the cylinder body, and setting a rotating device on the stirring device. However, the training device has a single function and cannot adjust the training program according to different usage situations, resulting in poor finger training effect for athletes and failing to effectively meet the practicality and overall training effect of the training device.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This judo athlete finger training device features connecting blades on the outside of a connecting rod. By rotating the connecting blades in the liquid inside the training cylinder with the handle, agitation training can be performed. Simultaneously, a first limiting mechanism is provided at the bottom of the connecting rod. The elastic rope can be limited by the first limiting mechanism and a second limiting mechanism at the bottom of the training cylinder. At this time, the finger grip strength training can be performed by moving the connecting rod upward with the handle. Furthermore, the upper surface of the training cylinder is equipped with a mounting plate, a second spring, and a limiting plate, which can rotate or extend with the connecting rod, increasing the overall load for finger training and improving the overall versatility and effectiveness of the training device. 2. This judo athlete finger training device allows for the limitation of the elastic rope within the training cylinder via a first and second limiting mechanism. Simultaneously, a mounting mechanism on the upper surface of the training cylinder limits the mounting plate. By removing the limitations on the elastic rope and mounting plate through the first, second, and mounting mechanisms, it is possible to quickly replace the elastic rope with one of different elastic strengths and the second spring at the top of the mounting plate. This effectively increases the training weight of the finger training device, improving its overall applicability. Furthermore, the replacement of the elastic rope and mounting plate requires finger coordination, thus providing further finger training during the replacement process. Attached Figure Description

By interlocking the second connecting blocks 705 on the two sets of limiting discs 703 with the connecting slots 706, the two sets of limiting discs 703 can be sleeved on the outside of the connecting rod 2. At the same time, the positioning rods 704 on the limiting discs 703 can be inserted into the positioning holes 203 on the connecting rod 2 to fix the position of the limiting discs 703 outside the connecting rod 2. At this time, the limiting discs 703 can pull the second spring 702 below as the connecting rod 2 rises and falls, or drive the second spring 702 to rotate synchronously with the mounting disc 7 as the connecting rod 2 rotates.

[0019] Example 2 differs from Example 1 mainly in that: A finger training device for judo athletes includes a training cylinder 1. A connecting rod 2 is slidably connected to the center of the upper surface of the training cylinder 1. A handle 201 is fixed to the center of the top of the connecting rod 2. Connecting fan blades 202 are fixed to the outer edges of the bottom of the connecting rod 2 at equal and uniform distances. A connecting seat 3 is fixed to the bottom of the connecting rod 2.

[0020] A water inlet 101 is fixed to the top left side of the training cylinder 1, a sealing door 102 is installed at the bottom right side of the training cylinder 1, a base plate 103 is fixed to the center of the lower surface of the training cylinder 1, the handle 201 is covered with the same high-density woven pure cotton material as the judo uniform, and multiple sets of water passage holes are provided on the connecting fan blade 202.

[0021] The first limiting mechanism 4 includes a movable groove 301 inside the right side of the connecting seat 3. A first pull ring 302 is slidably connected to the right side of the movable groove 301. A first connecting block 303 is fixedly connected to the left side of the first pull ring 302. A first spring 304 is fixedly connected to the right side of the first connecting block 303. An insert rod 305 is fixedly connected to the center position of the left side of the first connecting block 303. A fixing buckle 401 is slidably connected to the left side of the lower surface of the connecting seat 3. The fixing buckle 401 is U-shaped. A first limiting block 402 is fixedly connected to the left side of the upper surface of the fixing buckle 401. The first limiting block 402 slides inside the connecting seat 3. A connection point for the insert rod 305 is opened at the top right side of the fixing buckle 401. With the user's finger inside the first pull ring 302, the first connecting block 303 can be moved by pulling the first pull ring 302. At this time, the first connecting block 303 compresses the first spring 304, which can drive the insertion rod 305 to move. When the insertion rod 305 is pulled out from the slot 403 on the fixing buckle 401, the fixing buckle 401 can be pulled down. At this time, the elastic rope 6 can be put inside the fixing buckle 401 and inserted into the connecting seat 3 through the fixing buckle 401. At the same time, the insertion rod 305 is inserted into the slot 403 on the fixing buckle 401, which can complete the fixing work after the fixing buckle 401 is reset.

[0022] The second limiting mechanism 5 has the same specifications as the first limiting mechanism 4, both of which are equipped with a connecting seat 3, a movable groove 301, a first pull ring 302, a first connecting block 303, a first spring 304, a plug rod 305, a fixing buckle 401, a first limiting block 402, and a slot 403. The second limiting mechanism 5 is used to limit the lower end of the elastic rope 6. The lower end of the elastic rope 6 can be limited by the second limiting mechanism 5.

[0023] Positioning holes 203 are provided in the middle of the left and right sides of the connecting rod 2. Positioning rods 704 are fixedly connected to the center of the two limiting plates 703. The outside of the positioning rods 704 is inserted into the positioning holes 203. A second connecting block 705 is fixedly connected to the rear end of the right side of the left limiting plate 703. A connecting groove 706 is provided at the front end of the right side of the left limiting plate 703. A second connecting block 705 and a connecting groove 706 are provided on the left side of the right limiting plate 703, which are staggered with the position of the left limiting plate 703. The second connecting blocks 705 and connecting grooves 706 on both limiting plates 703 can be inserted into each other.

[0024] The mounting mechanism 8 includes an annular groove 707 on the outside of the mounting plate 7, and square grooves 801 evenly spaced around the inside of the upper surface of the training cylinder 1. A screw 802 is threaded onto the outside of the square groove 801, and a square block 803 is rotatably connected to the inside of the screw 802. A second limiting block 804, which engages with the annular groove 707, is fixed to the inside of the square block 803. Rotation of the square groove 801 can push the second limiting block 804 to move through the square block 803. When the second limiting block 804 is inserted into the positioning rod 704 on the mounting plate 7, the mounting plate 7 can be positioned on the upper surface of the training cylinder 1. When the second limiting block 804 is pulled out from the annular groove 707 on the mounting plate 7, the athlete can lift the mounting plate 7 from the upper surface of the training cylinder 1 by holding the second pull ring 701 with their fingers.

[0025] The square groove 801 and the square block 803 have the same specifications. The square block 803 can only reciprocate in one direction inside the square groove 801. At the same time, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0026] In this embodiment, during use: water can be injected into the training cylinder 1 by opening the inlet 101. The athlete grips the handle 201 and rotates it. The handle 201 then drives the connecting fan blades 202 to agitate the water inside the training cylinder 1, increasing the athlete's finger strength. Simultaneously, the athlete can use the handle 201 to move the connecting rod 2 up and down. The connecting rod 2 can then stretch the elastic rope 6 below via the connecting seat 3. Simultaneously, the connecting rod 2 can pull the second spring 702 below via the limiting plate 703, thus training finger grip strength. When the sealing door 102 on the training cylinder 1 is opened, the water inside the training cylinder 1 can be discharged. At this time, the athlete's fingers grip the first limiting mechanism 4 and the second limiting mechanism 5. Inside the pull ring 302, by pulling the first pull ring 302, the first pull ring 302 can drive the insertion rod 305 to be pulled out from the slot 403 on the fixing buckle 401 through the first connecting block 303. At this time, the fixing buckle 401 on the first limiting mechanism 4 and the second limiting mechanism 5 can cancel the limitation on the elastic rope 6, and the elastic rope 6 can be replaced. At the same time, by rotating the screw 802 on the training cylinder 1, the screw 802 can drive the second limiting block 804 to be pulled out from the annular groove 707 on the mounting plate 7 through the square block 803. At this time, the athlete's finger is hooked into the second pull ring 701 at the top of the mounting plate 7, and the mounting plate 7 is pulled upward, so that the mounting plate 7 can be pulled out from the top of the training cylinder 1. At this time, the mounting plate 7, the second pull ring 701, and the limiting plate 703 can be removed and replaced.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
