Description

A split test device

technical field

The invention belongs to a kind of sports equipment for testing, in particular to a splitting test device.

Background technique

As we all know, flexibility is a very important physical quality. Various sports such as dance, gymnastics, acrobatics, and martial arts have very high requirements on people's flexibility. The splits are a very important exercise form and practice method to improve the flexibility of the lower limbs.

When the human body splits, the height that the legs can press down is a detectable indicator for measuring the flexibility of the human body. Generally speaking, when the human body splits to the maximum, the height between the crotch and the ground can be measured with a ruler , although this method is intuitive and convenient, it is not elegant and the human body instinctively rejects it.

In addition, when the human body does the splits, in order to get as close to the ground as possible, the body will involuntarily lean forward. In fact, this tilt will indeed make the splits closer to the ground. Compensation, resulting in inaccurate measurement data, it is difficult to accurately evaluate the split height of each athlete, and it is also impossible to effectively compare the flexibility of each athlete. This kind of inclination needs to be limited. Generally speaking, manual correction by supervisors can be used. To achieve this goal, but this method also leads to inconsistent movements and wastes manpower.

Chinese patent No. ZL201520239801.3 discloses a leg stretching fitness device, which includes a main frame, two rotatable pedals on the main frame, a horizontally slidable sliding device and a device at the bottom of the pedals. There are height-adjustable grip bars on both sides of the main frame. There are also induction devices and LED displays on the main frame. The two pedals can have two splitting functions: horizontal splits and vertical splits by rotating. The ultrasonic distance sensing device of the sensing device passes The distance between the pedal and the sensor is sensed, and the processed data (that is, the distance of the leg stretched) is displayed on the LED display. However, this device has a complex structure, and it cannot guarantee that the testee's splitting action is in compliance with the standard, and irregular actions lead to inaccurate split heights, which cannot represent the true level of the testee.

detailed description

As shown in Fig. 1, Fig. 2 and Fig. 3, the present invention comprises a base 1, a chute 2 arranged in the base 1, a slider II 8 installed on the chute 2 and limited by the chute 2, a displacement sensor, a single-chip microcomputer, a display And a vertically installed casing 5 fixed on the base 1, a measuring rod 6 is sleeved in the casing 5, and an end block 61 is fixed at the end of the measuring rod 6, and a sleeve is arranged between the base 1 and the end block 61. The spring II14 on the casing 5, the chute 2 is provided with a connecting pipe I71, the slider II8 slides along the connecting pipe I71, the connecting pipe I71 is connected to the piston sleeve 9 through the connecting pipe II72, and the piston sleeve 9 is set with a piston Rod 10, the other end of the piston rod 10 is provided with a limiting plate 11 for limiting the position of the body when the human body splits. Spring I13 on 10; the displacement sensor is used to measure the displacement of end block 61 movement, the displacement sensor is connected with the single-chip microcomputer, and the single-chip microcomputer is connected with the display.

The present invention uses a displacement sensor to measure the moving distance of the object, and transmits the data to the display through a single-chip microcomputer, which is a prior art, and those skilled in the art know how to realize it.

When the present invention measures the height of the crotch and the ground during the splitting action, the human body stands on the base 1, and the crotch is facing the measuring rod 6. 5 is socketed, the measuring rod 6 moves downward, squeezes the sleeve 5, and the displacement sensor measures the displacement of the end block 61, that is, the distance that the crotch is pressed down. The single-chip microcomputer transmits the data of the above-mentioned distance to the display for easy reading. The above distance data are used to measure the splitting ability of the human body and evaluate the flexibility of the human body. After the measurement, the spring II 14 returns the end block 61 to the initial position for the next tester to test.

When the human body is doing the splits test, the feet need to move forward. Place the feet of the human body on the upper end or the side of the slider Ⅱ8, push the slider Ⅱ8 to move, the slider Ⅱ8 squeezes the spring Ⅰ13, pushes the piston rod 10 to move, and the piston The limit plate 11 fixedly connected to the rod 10 moves toward the human body to limit the inclination of the human body and prevent motion compensation.

The joints between the connecting pipe I71 and the connecting pipe II72, and the connecting pipe II72 and the piston sleeve 9 are arc-shaped, which is convenient for the spring I13 to expand and contract.

The upper end of the sleeve pipe 5 of the present invention is flush with the horizontal plane of the base 1, even if the crotch of the human body is in contact with the base 1 when splitting, it can be effectively measured.

The height between the limiting plate 11 and the base 1 of the present invention is at an appropriate position, which is used to limit the person from leaning forward, or to limit the position of the human body by changing the height of the limiting plate 11 itself.

After the body of the detected person touches the limit plate 11, the detected person is reminded to control the forward inclination of the human body and limit its forward inclination. The piston rod 10 of the present invention can be designed as a telescopic type. When the height of the splits of the detected personnel is very different, the approximate distance between the limit plate 11 and the human body can be adjusted by adjusting the length of the piston rod 10, so that it can reach intended target.

The end of the measuring rod 6 is equipped with an end block 61, the cross-sectional area of the end block 61 is larger than that of the measuring rod 6, and the surface softness is better than that of the measuring rod 6. On the one hand, the width of the contact between the measuring rod 6 and the crotch is enlarged , On the other hand, it also improves user usability.

The limiting plate 11 and the piston rod 10 are connected by a hinge 12, and the surface of the limiting plate 11 and the piston rod 10 are horizontal or vertical. When the detected person measures the vertical split, the limiting plate 11 is perpendicular to the piston rod 10, and when the human body splits, the limiting plate 11 moves forward to limit the position of the body and prevent motion compensation. When the detected person measures the horizontal split, the limit plate 11 and the piston rod 10 are horizontal, as shown in FIG. 3 . When the human body splits, the limiting plate 11 moves forward to limit the position of the body and prevent motion compensation. The limitation of the present invention not only refers to the direct contact of the physical space, but also includes the psychological limitation brought about by the movement of the limiting plate 11 and the reduction of the distance between the limiting plate 11 and the human body.

The base 1 is provided with a chute 2, and the feet move along the chute 2 when the human body splits, so as to limit the position of the human body and ensure the consistency of everyone's actions. The smoothness of the surface of the chute 2 is high, which is convenient for the human body to split.

A slider I4 is arranged in the chute 2 to move along the chute 2. The slider I4 and the slider II8 play a role of guiding and restricting, guiding the movement of the foot, and restricting the movement of the foot beyond the specified range. The feet of the person to be detected can be located on the slide block I4 and the slide block II8, or at the side ends of the slide block I4 and the slide block II8.

A spring is provided between the slider I4 and the end of the base 1 for the reset of the slider I4 and the slider II8.

A groove 3 is installed on the base 1 , and the connecting pipe I71 is installed in the groove 3 .

A baffle 41 is installed at the end of the chute 2 to prevent the slider I4 and the slider II8 from sliding out of the chute 2 .

The vertical installation in the present invention not only refers to the 90° between the two, but also includes an angle that generally extends to the vertical direction, such as 45-90°.
