Description

Technical Field

[0001] This utility model relates to the field of hand shape correctors, and in particular to a volleyball passing hand shape corrector. Background Technology

[0002] In volleyball training, the correct passing hand shape (especially the front two-handed pass) is crucial for ball control stability. In order to train the passing hand shape and make it more standard, physical restrictions or tactile feedback are generally used to force the formation of the correct hand shape (the ten fingers are naturally spread out in a hemispherical shape, the thumb is in an "eight" shape, and only the fingertips touch the ball).

[0003] Currently, hand shape correction devices are divided into various types, including thumb positioning rings (using silicone to fix the thumb and index finger in a figure-eight shape to prevent the thumb from extending forward), finger limiting bands (elastic bands connecting the five fingers to limit excessive opening or closing), and palm anti-touch plates (lightweight plastic plates added to the back of the hand to prevent the palm from pressing forward and touching the ball when moving down). At present, finger limiting bands are made of rubber, silicone, or elastic fibers. Long-term stretching will cause molecular bonds to break and elasticity to decrease, making it unable to provide sufficient rebound force, resulting in uncontrolled finger spacing and excessive finger opening, which will have an adverse effect on hand shape correction. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a volleyball passing hand shape corrector, which aims to improve the problems in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a volleyball passing hand shape corrector, comprising:

[0006] The elastic connecting plate has two tension straps fixedly installed on both sides, and one end of each of the four tension straps is fixedly installed with a finger ring that fits onto the fingers other than the thumb.

[0007] An adjusting component is provided at one end of the elastic connecting plate, and an elastic band is provided at one end of the adjusting component. One end of the elastic band is fixedly installed with a ring two for interlocking with the thumb. The adjusting component is used to control the distance between the ring two and the elastic connecting plate, and to ensure that the fingers are always in a standard passing hand position.

[0008] As a further description of the above technical solution:

[0009] The adjusting component includes a fixed plate and a sliding rod. One end of the elastic connecting plate is provided with a fixed plate. One end of the fixed plate has a mounting hole that communicates with the other end. A threaded tube is rotatably installed in the inner cavity of the mounting hole. Sliding rods are symmetrically installed in the inner cavity of the threaded tube. One end of one of the sliding rods, extending to the outside of the threaded tube, is fixedly connected to one end of the elastic connecting plate. One end of the elastic band is fixedly connected to the end of one of the sliding rods extending to the outside of the threaded tube. The outer walls of the two sliding rods have threaded grooves with opposite rotation directions.

[0010] As a further description of the above technical solution:

[0011] An adjusting disc is fixedly sleeved in the middle of the threaded pipe, and receiving grooves for the adjustment disc to rotate are provided on both sides of the fixing plate.

[0012] As a further description of the above technical solution:

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1-4 One embodiment of this utility model is a volleyball passing hand shape corrector, comprising:

[0028] The elastic connecting plate 1 has two tension bands 2 fixedly installed on both sides. One end of each of the four tension bands 2 is fixedly installed with a finger ring 3 that fits onto the fingers other than the thumb. When the hand shape needs to be corrected, the four finger rings 3 are respectively fitted onto the outside of the four fingers other than the thumb. The four finger rings 3 are located at the second joint of the four fingers. At this time, the elastic connecting plate 1 is located directly above the palm. When the four fingers other than the thumb open or close, the four finger rings 3 move accordingly (this is existing technology and will not be described in detail here).

[0029] The adjusting component includes a fixed plate 4 and sliding rods 8. A fixed plate 4 is provided at one end of an elastic connecting plate 1. One end of the fixed plate 4 has a mounting hole communicating with the other end. A threaded tube 9 is rotatably installed in the inner cavity of the mounting hole. Sliding rods 8 are symmetrically installed in the inner cavity of the threaded tube 9. One end of one sliding rod 8 extending outside the threaded tube 9 is fixedly connected to one end of the elastic connecting plate 1. An elastic band 5 is fixedly installed at the other end of the sliding rod 8 extending outside the threaded tube 9. A ring 6 is fixedly installed at one end of the elastic band 5. The outer walls of the two sliding rods 8 have threaded grooves with opposite rotation directions. After the four rings 3 are respectively attached to the outside of the four fingers excluding the thumb, the ring 6 is attached to the first joint of the thumb. When the five fingers are spread, the four tension bands 2 and the four rings 3 deform and apply a pulling force to the four fingers to move closer to the elastic connecting plate 1. The elastic band 5 and the ring 6 apply a pulling force to the thumb to move closer to the elastic connecting plate 1. Thus, with the cooperation of the elastic band 5 and the four tension bands 2, a pulling force is applied to the five fingers to pull them together towards the palm, thereby limiting the position of the five fingers and restricting the five fingers from being too spread or closed.

[0030] The elastic connecting plate 1, tension band 2, finger ring 1 3, finger ring 2 6, and elastic band 5 are all made of rubber. When the five fingers are in the standard hand shape for volleyball passing, the elastic connecting plate 1, tension band 2, and elastic band 5 can apply pressure to the outside of the fingers. The continuous pressure stimulation allows the brain to perceive the standard hand shape more clearly and accelerates the formation of the regulatory reflex. When the elastic connecting plate 1, tension band 2, and elastic band 5 apply pressure to the five fingers, finger ring 2 6 and the four finger rings 1 3 are softly connected to the outer wall of the fingers to prevent the fingers from being damaged or swollen due to excessive pressure. This improves the wearing comfort of finger ring 2 6 and the four finger rings 1 3, and increases the duration of continuous correction of the passing hand shape.

[0031] According to the applicant's understanding of the prior art, since the elastic connecting plate 1, tension band 2 and elastic band 5 are made of rubber material, long-term stretching will cause the molecular bonds to break and the elasticity to decrease, making it unable to provide sufficient rebound force, causing the elastic connecting plate 1, tension band 2 and elastic band 5 to become loose, resulting in loss of control over the finger spacing.

[0032] To solve the above problems, an adjusting disc 11 is fixedly sleeved in the middle of the threaded tube 9. The fixed plate 4 has accommodating grooves on both sides for the rotation of the adjusting disc 11. When the elastic connecting plate 1, tension band 2, and elastic band 5 become loose after long-term stretching, firstly, finger ring 6 is sleeved on the first joint of the thumb, then four finger rings 3 are sleeved on the second joints of the other four fingers. Then, the adjusting disc 11 is continuously rotated, causing the threaded tube 9 to rotate. At this time, the elastic band 5 moves towards the fixed plate 4 along with the connected sliding rod 8. Since the rotation directions of the threaded grooves on the outer walls of the two sliding rods 8 are opposite, the other sliding rod 8 pulls the elastic connecting plate 1 towards the fixed plate 4. When the elastic band 5 moves towards the fixed plate 4, it is stretched away from the thumb, causing the thumb to move towards the palm. When the elastic connecting plate 1 moves towards the fixed plate 4, it applies a pulling force to the four tension bands 2 towards the palm, causing the four fingers other than the thumb to come together towards the palm. The adjustment disc 11 stops rotating when all five fingers are in the standard passing hand position. With the help of the threads, the two sliding rods 8 can be limited after movement, preventing them from resetting. This allows for precise control of the finger spacing, preventing the five fingers from spreading too wide and avoiding adverse effects on hand position correction.

[0033] The outer wall of the threaded tube 9 is fixedly sleeved with a drive bearing that is connected to the inner wall of the mounting hole. The drive bearing can support the threaded tube 9, allowing it to rotate stably in the inner cavity of the mounting hole. At the same time, it reduces the friction when the threaded tube 9 rotates and improves the smoothness of its rotation.

[0034] The adjusting component consists of a fixed plate 4, a threaded tube 9, and a sliding rod 8. The distance between the finger ring 6 and the elastic connecting plate 1 can be controlled by the adjusting component, and the finger can always be in the standard passing hand position.

[0035] According to the applicant's understanding of the prior art, when correcting hand shape for users with large hands, the elastic band 5 and the four tension bands 2 exert a large reverse pulling force on the fingers when the user's palm is open, which causes the user's fingers to be over-restrained, affecting blood circulation in the fingers and resulting in numbness or pain in the fingers.

[0036] To solve the above technical problems, the adjustment disc 11 is rotated in the opposite direction, which allows the two sliders 8 to move away from each other, thereby reducing the tension exerted on the fingers by the elastic band 5 and the four tension bands 2, preventing the user's fingers from being overly restricted, avoiding affecting the blood circulation of the fingers, and preventing pain or numbness in the fingers.

[0037] The sliding rod 8 is designed with a T-shaped structure. The large ends of the two sliding rods 8 are fixedly connected to one end of the elastic connecting plate 1 and the elastic band 5, respectively. This can increase the connection area between the sliding rod 8 and one end of the elastic connecting plate 1 and the elastic band 5, thereby increasing the strength of the connection between the sliding rod 8 and the elastic connecting plate 1 and the elastic band 5, preventing the sliding rod 8 from breaking during finger correction, and extending the service life of the device.

[0038] Guide holes are provided at both ends of the fixed plate 4. Two guide rods 10 are slidably installed in the inner cavity of the guide holes. The ends of the two guide rods 10 extending outside the guide holes are fixedly connected to the large ends of the two slide rods 8 respectively. When the two slide rods 8 move, the two guide rods 10 move in the inner cavity of the same guide hole, thereby limiting the movement trajectory of the two slide rods 8. This prevents the slide rods 8 from rotating together with the threaded tube 9, which would cause the second finger ring 6 and the four first finger rings 3 to apply pressure to the side wall of the finger at the same time. This further improves the wearing comfort of the device and the durability of the passing hand shape.

[0039] According to the applicant's understanding of the prior art, after the second ring 6 and the four first rings 3 are worn on the outside of the fingers, the tension exerted on the second ring 6 and the first rings 3 by the elastic band 5 and the tension band 2 causes the four first rings 3 to slide towards the third joint and the second ring 6 to slide towards the second joint. This reduces the tension exerted on the fingers by the elastic band 5 and the tension band 2, making it impossible for the user to maintain the correct passing hand position for a long time.

[0040] To address the aforementioned issues, one end of ring 2 6 and one end of each of the rings 1 3 are fixedly fitted with limiting sleeves 7 for self-limitation. When ring 2 6 and the four rings 1 3 are fitted onto the outside of the fingers, the five limiting sleeves 7 are fitted onto the outside of the fingertips, wrapping around the five fingers and the first joint, preventing the four rings 1 3 from easily sliding towards the third joint and the ring 2 6 from easily sliding towards the second joint. This ensures the tensile strength of the elastic band 5 and the tension band 2 on the fingers, allowing the user to maintain the correct passing hand position for a long time.

[0041] The limiting sleeve 7 is made of rubber material, which gives it a certain degree of plastic deformation capability. When the limiting sleeve 7 is pressed against the user's fingertips, it can deform to a certain extent, which improves the user's wearing comfort.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
