Description

Technical Field

[0001] This utility model relates to the field of wrist strength training technology, and in particular to a wrist strength training device for physical education. Background Technology

[0002] Wrist exercisers, as the name suggests, are used to train wrist strength. They can be used to train the forearm muscles, such as the palmar forearm muscles, flexor muscles, and finger muscles. Long-term practice can achieve the goal of fitness and strength (with a focus on the forearm). The wrist is an important part of the human body, especially for badminton, tennis, volleyball, and basketball players. After using a wrist exerciser for a period of time, wrist strength will increase significantly, which is most directly helpful for these sports.

[0003] A search revealed that Chinese patent number CN207679966U discloses a wrist strength training device for sports teaching, including a spring. The curved section of the spring is fitted with a buffer sleeve, and two tube sleeves are fitted on the spring at the middle position away from the buffer sleeve. Both tube sleeves are located on the same side of the buffer sleeve, and each tube sleeve is fitted with a strap. A fixing strap connects the two straps. A handle is fixed to the end of the spring away from the buffer sleeve, and the two ends of the handle are respectively engaged with a first end cap and a second end cap. A fixing rod is screwed to the end of the first end cap near the handle, and the fixing rod penetrates the interior of the absorbent cotton.

[0004] The aforementioned document improves the function of the handle on the basis of the traditional wrist exerciser by adding a cylindrical absorbent cotton to the handle and opening through holes in the cotton to absorb sweat and prevent the hands from slipping. However, like the traditional wrist exerciser, it still has some shortcomings in use. First, the elasticity of the spring in the wrist exerciser is fixed. At the same time, the bending angle of the human wrist is limited. Therefore, when the user's wrist is bent to the maximum, the elasticity of the spring may not be able to meet the user's training needs, resulting in poor training effect.

[0005] To address the aforementioned shortcomings, this application proposes a wrist strength training device for physical education. Utility Model Content

[0006] This invention provides a wrist strength training device for physical education to solve the above-mentioned technical problems.

[0007] To solve the above-mentioned technical problems, this utility model provides a wrist strength training device for sports teaching, including a pressure arm mechanism. The pressure arm mechanism includes an arc-shaped plate, a threaded rod is connected through the top of the arc-shaped plate, an arc-shaped pressure rod is movably connected to the bottom of the threaded rod, a soft sleeve is sleeved on the outer end of the arc-shaped pressure rod, and a rotating handle is fixedly connected to the top of the threaded rod.

[0008] A handle is connected to the rear of the pressure arm mechanism. The handle includes a U-shaped handle. Two springs are fixedly connected between the arc plate and the U-shaped handle. A wrist pressure sleeve is sleeved between the two springs.

[0009] Preferably, the handle further includes a pressure handle located inside the U-shaped handle. A pressure sensor is embedded at the top of the U-shaped handle. An installation chamber is formed inside the U-shaped handle, and a button battery and a control main board are fixedly connected inside the installation chamber. A display screen is embedded at the top of the U-shaped handle and is located above the installation chamber. The pressure sensor, button battery, and display screen are electrically connected to the control main board.

[0010] Preferably, a limiting slider is fixedly connected to each side of the pressure handle, and a limiting groove is opened on each side of the inside of the U-shaped handle. The limiting slider is located inside the limiting groove, and the U-shaped handle and the pressure handle are movably connected through the limiting groove and the limiting slider.

[0011] Preferably, the rear side of both the U-shaped handle and the pressure handle is machined with multiple arc-shaped grooves.

[0012] Preferably, the top of the arc-shaped plate is thickened at the connection with the threaded rod, and the top of the soft sleeve has an opening through which the threaded rod passes.

[0013] Compared with related technologies, the wrist strength training device for physical education provided by this utility model has the following beneficial effects:

[0014] 1. By adjusting the pressure arm mechanism, the spring can bend earlier to increase its initial elastic force. This allows for adjustment of the wrist strength training resistance according to actual usage needs, meeting the training needs of different users. It is convenient to use and provides better training results.

[0015] 2. By changing the handle of the traditional wrist exerciser to a separate U-shaped handle and pressure handle, and installing a pressure sensor between the U-shaped handle and pressure handle, the pressure value detected by the pressure sensor can be displayed on the screen. During wrist strength training, the value detected by the pressure sensor can, to a certain extent, reflect the intensity of the user's wrist strength training, making the wrist strength training effect more intuitive.

Detailed Implementation

[0024] Implementation examples, by Figure 1-7 The present invention includes a pressure arm mechanism, wherein the pressure arm mechanism includes an arc plate 1, a threaded rod 2 is connected through the top of the arc plate 1, an arc-shaped pressure rod 4 is movably connected to the bottom of the threaded rod 2, a soft sleeve 5 is sleeved on the outer end of the arc-shaped pressure rod 4, and a rotating handle 3 is fixedly connected to the top of the threaded rod 2.

[0025] A handle 8 is connected to the rear of the pressure arm mechanism. The handle 8 includes a U-shaped handle 81. Two springs 6 are fixedly connected between the arc plate 1 and the U-shaped handle 81. A wrist pressure sleeve 7 is sleeved between the two springs 6.

[0026] The handle 8 also includes a pressure handle 82 located inside a U-shaped handle 81. A pressure sensor 9 is embedded at the top of the U-shaped handle 81. An installation chamber 10 is formed inside the U-shaped handle 81, and a button battery 11 and a control board 12 are fixedly connected inside the installation chamber 10. A display screen 13 is embedded at the top of the U-shaped handle 81, located above the installation chamber 10. The pressure sensor 9, button battery 11, and display screen 13 are electrically connected to the control board 12. During wrist strength training, the user holds the handle 8 from bottom to top, so the palm first contacts the pressure handle 82. The palm pushes the pressure handle 82 to compress the U-shaped handle 81. The pressure value detected by the pressure sensor 9 at this time reflects the intensity of the wrist strength training.

[0027] A limiting slider 821 is fixedly connected to each side of the pressure handle 82. A limiting groove 811 is formed on each side of the inside of the U-shaped handle 81. The limiting slider 821 is located inside the limiting groove 811. The U-shaped handle 81 and the pressure handle 82 are movably connected through the limiting groove 811 and the limiting slider 821. The U-shaped handle 81 and the pressure handle 82 are movably connected through the limiting groove 811 and the limiting slider 821, which not only allows for a certain amount of movement between the U-shaped handle 81 and the pressure handle 82 to facilitate the detection by the pressure sensor 9, but also prevents the pressure handle 82 from falling off the U-shaped handle 81.

[0028] The rear sides of both the U-shaped handle 81 and the pressure handle 82 are machined with multiple arc-shaped grooves. The design of the arc-shaped grooves can make the fingers feel better when holding the handle 8, and the overall use comfort is better.

[0029] The top of the arc plate 1 is thickened at the connection with the threaded rod 2. The top of the soft sleeve 5 has an opening through which the threaded rod 2 passes. The thickened part on the arc plate 1 can improve the connection stability between it and the threaded rod 2. The opening on the soft sleeve 5 can prevent the threaded rod 2 from interfering with the soft sleeve 5. The soft sleeve 5 can improve the comfort of the arc-shaped pressure rod 4 pressing on the arm.

[0030] Working principle:

[0031] When in use, the user's arm passes through the arm-pressing mechanism and the two springs 6, and the wrist-pressing sleeve 7 is placed on the back of the wrist. Then, the user holds the handle 8 with their hand and bends their wrist. Since the handle 8 and the arm-pressing mechanism at both ends of the spring 6 are located at the hand and arm positions respectively, the spring 6 will bend. When the spring 6 bends, its own elasticity acts as resistance, which can achieve the purpose of training wrist strength.

[0032] When the elasticity of spring 6 is insufficient to meet the user's wrist strength training needs, the user can hold the handle 3 and rotate the threaded rod 2, so that the threaded rod 2 pushes the arc-shaped pressure rod 4 closer to the arm until the pressure arm mechanism presses on the user's arm. Before the wrist is bent, spring 6 is already in a certain bent state, which increases the initial elasticity of spring 6. When the user holds the handle 8 and bends the wrist, spring 6 bends further. The greater the bending of spring 6, the greater its rebound force, that is, the greater the resistance, thus meeting the greater wrist strength training needs.

[0033] When holding the handle 8 for wrist strength training, the palm pushes the pressure handle 82 to squeeze the U-shaped handle 81, and the pressure sensor 9 detects the squeezing pressure between the U-shaped handle 81 and the pressure handle 82 and displays the pressure value on the display screen 13. This pressure value can, to some extent, reflect the intensity of the user's wrist strength training.
