Description

Technical Field

[0001] The present invention relates to the technical field of sports equipment, and more specifically, to a running aid for sports training. Background Art

[0002] The running block used in sports training is used for support during the start, which allows the athletes to exert better force when starting. The running block is generally composed of a rack and two pedals. The pedals can be engaged in different positions of the rack, so that the running block can adapt to different athletes and can help athletes obtain extremely high acceleration in an instant.

[0003] However, the pedal angle is adjusted by an overall rotation method, and the surface shape of the pedal will not change accordingly. Since the rotated pedal forms a straight-line inclination angle with the ground, the force of the running-starting burst is greater than the inclination angle of the pedal. The straight-line inclination of the pedal tends to make the contact force between the sole of the foot and the pedal smaller, which in turn causes a greater contact and squeezing pressure between the toes and the ground, affecting the overall explosive power of the foot. The pedal is vertically clamped and fixed on the rack. According to the direction of the athlete at the start, a thrust will be generated to the lower right during the starting burst. The vertical clamping fixation can easily disperse the thrust into rightward and downward forces. When the friction fixing force below the rack is weak, the excessive force to the right can easily cause the rack to leave the ground. Summary of the invention

Beneficial Effects

[0010] 1.

[0011] 2. In the present invention, when the toes are on the arc plate, the trapezoidal block is squeezed, and under the squeezing support of the plastic plate, the foot is squeezed on the friction strip during the running start, so that the bending plate is bent under force to bear the force on the foot, presenting an arc-shaped state to support the sole of the foot, and the toe part is buffered under the support of the trapezoidal block, so that the bearing force is evenly distributed in various parts of the sole of the foot, preventing the toe part from being squeezed too heavy due to the tilt of the straight state, so that the arc plate keeps blocking under the pressure of the foot, avoiding too small contact force on the sole of the foot, and preventing the toe part from bearing too much force to affect the explosive power.

[0012] 3. In the present invention, the support plate on the outer side of the parallel plate enters the inclined groove and engages. Under the extrusion of the extrusion block, the deformation plate is driven to compress toward the friction plate, so that the friction plate fills the gap in the inclined groove to prevent the gap from affecting stability during the explosive run-up. According to the principle of force action, the limit plate in the inclined state reversely blocks the explosive force on the upper left, so that after the explosive force is decomposed, the vertical downward force is greater than the rightward force, avoiding excessive rightward force that easily causes the horizontal plate to leave the ground.

[0023] The receiving structure 43 is provided with a plastic plate w1, a trapezoidal block w2, a circular hole w3, an arc plate w4, and a bearing plate w5. The plastic plate w1 is embedded in the upper end of the bearing plate w5. The arc plate w4 is located above the trapezoidal block w2 and the plastic plate w1. The trapezoidal block w2 is located on the left side of the bearing plate w5. The circular hole w3 is movably matched with the right end of the bearing plate w5. The arc plate w4 and the left end of the bearing plate w5 are installed on the inner side of the parallel plate 44. The telescopic mechanism 42 is embedded in the right end of the bearing plate w5. There are six circular holes w3, which are evenly arranged in an arc state. The trapezoidal block w2 is made of rubber and has the characteristic of extrusion deformation. The load-bearing plate w5 is made of aluminum alloy and has the characteristic of bending under force, so that the foot is pressed on the arc plate w4. By adjusting the position of the right end of the load-bearing plate w5 on the circular hole w3, the load-bearing plate w5 adjusts the inclination angle above the plastic plate w1, and then the arc plate w4 rotates with the left end as the center. When the toes are on the arc plate w4, the trapezoidal block w2 is squeezed, and under the squeezing of the plastic plate w1, the arc plate w4 is kept blocked under the pressure of the foot to avoid too small contact force on the sole of the foot and prevent the toes from bearing too much force.

[0024] Among them, the arc plate w4 is provided with a rotating rod w41, a bending plate w42, and a friction strip w43. The bending plate w42 is embedded in the side of the rotating rod w41, and the friction strip w43 is attached to the surface of the bending plate w42. The rotating rod w41 is installed on the inner side of the parallel plate 44. The friction strip w43 is made of silicone rubber material, which has the characteristics of rough surface and large friction. The bending plate w42 is made of aluminum alloy, which has the characteristics of strong toughness and bending under force. Therefore, under the support of the plastic plate w1, the bending plate w42 is rotated and adjusted around the rotating rod w41 as the center, and then the foot is squeezed on the friction strip w43 during the running start, so that the bending plate w42 is bent under force to bear the force on the foot, thereby preventing excessive tilt from causing excessive squeezing force on the toes.

The spring rod s2 is embedded in the side of the metal block s4, the metal block s4 is welded to the side of the metal block s4, the moving rod s1 is slidably matched inside the cylindrical tube s3, the round rod s5 is installed at the left end of the spring rod s2, the round rod s5 is slidably matched with the inside of the cylindrical tube s3, the cylindrical tube s3 and the metal block s4 are embedded in the side of the receiving structure 43, the round rod s5 is connected to the parallel plate 44 are engaged with each other, and the round rod s5 is in a left-right symmetrical state with the metal block s4 as the center. A ball is provided on the left side of the cylindrical tube s3 to slide with the round rod s5, so that the left and right sides press the moving rod s1 at the same time, driving the round rod s5 to be squeezed and stretched toward the spring rod s2, thereby making the round rod s5 detach from the position on the parallel plate 44. After adjusting the position, the moving rod s1 is released, and the round rod s5 is re-engaged at a different position on the parallel plate 44 under the elastic force of the spring rod s2, thereby adjusting the inclination angle of the receiving structure 43. The specific usage and function of this embodiment are as follows: In the present invention, the spacing is adjusted by adjusting the position of the force-bearing structure 41 in the foot pedal 4 engaged on the rack 5, and can be accurately adjusted under the display of the scale line 3, and the slope of the supporting structure 43 is adjusted by manually controlling the position of the telescopic mechanism 42 engaged on the parallel plate 44. During adjustment, the moving rods s1 on the left and right sides of the telescopic mechanism 42 are manually pressed to drive the round rod s5 to be squeezed and extended toward the spring rod s2, thereby causing the round rod s5 to be separated from the position on the parallel plate 44, causing the force-bearing plate w5 to rotate on the parallel plate 44, thereby pushing the arc plate w4 to rotate. After adjusting the position, the moving rod s1 is released, and the round rod s5 is re-engaged in different positions of the circular hole w3 under the elastic force of the spring rod s2, thereby adjusting the inclination angle of the arc plate w4.

[0026] In the present invention, by adjusting the position of the telescopic mechanism 42 at the right end of the load-bearing plate w5 on the circular hole w3, the arc plate w4 is rotated and adjusted with the bending plate w42 and the rotating rod w41 as the center.

The limiting plate t2 is welded on the side of the supporting plate t1, and the limiting plate t2 is engaged in the inclined groove t3. The extrusion block t4 is extruded and moved with the limiting plate t2, and the extrusion block t4 is welded on the inner side of the rack 5. The supporting plate t1 is welded on the outer side of the parallel plate 44, and the limiting plate t2 is installed at an angle of 15 degrees. The extrusion block t4 is an arc structure with an extrusion effect, so that the supporting plate t1 on the outer side of the parallel plate 44 enters and engages in the inclined groove t3. Under the extrusion of the extrusion block t4, the limiting plate t2 expands and fills the inclined groove t3 to prevent the gap from affecting the stability during the explosive run-up, and according to the principle of force action, the limiting plate t2 in an inclined state reversely blocks the explosive force on the upper left, so that after the explosive force is decomposed, the vertical downward force is greater than the rightward force, so as to avoid the rightward force being too large and easily causing the horizontal plate 1 to leave the ground.

[0028] Among them, the limiting plate t2 is provided with a fixed plate t21, a friction plate t22, and a deformation plate t23. The deformation plate t23 is attached to the inner side of the fixed plate t21, and the friction plate t22 is embedded on the outer side of the deformation plate t23. The fixed plate t21 is welded to the side of the support plate t1. The deformation plate t23 is made of rubber and has the characteristic of extrusion activity. Therefore, the deformation plate t23 is deformed after being squeezed by the extrusion block t4, driving the deformation plate t23 to be compressed toward the friction plate t22, so that the friction plate t22 fills the gap in the inclined groove t3 to prevent the occurrence of gaps at the engaging position. The specific usage and function of this embodiment are as follows: In the present invention, the support plate t1 on the outer side of the parallel plate 44 enters and engages in the inclined groove t3. Under the extrusion of the extrusion block t4, the deformation plate t23 is deformed after being squeezed by the extrusion block t4, driving the deformation plate t23 to compress toward the friction plate t22, so that the friction plate t22 fills the gap in the inclined groove t3, and the limiting plate t2 expands to fill the inclined groove t3, so as to prevent the gap from affecting the stability during the explosive run-up. According to the principle of force action, the limiting plate t2 in the inclined state reversely blocks the explosive force from the upper left, so that after the explosive force is decomposed, the vertical downward force is greater than the rightward force, so as to avoid the rightward force being too large and easily causing the horizontal plate 1 to leave the ground.
