Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of measurement, and particularly relates to an inclined body chin-up measurement device. Background Art
[0002] At present, when students do the inclined body chin-up project, a very small teaching triangular ruler is usually placed to try to evaluate the standardization of the movement, that is, whether the angle between the body and the ground is less than 45 degrees. However, this method has some problems, which limits the effectiveness of teaching and testing.
[0003] First of all, due to its small size, it may be difficult for students and coaches to accurately align and measure the angle with the small teaching triangular ruler, resulting in uncertainty in the evaluation results; secondly, in a fast-paced training or testing environment, students may not be able to accurately align with the triangular ruler during the movement process, thus affecting the accuracy and consistency of the evaluation; finally, the small triangular ruler may not be stable enough and is prone to displacement or movement during use, resulting in errors and inconsistencies, affecting the teaching and testing results and unable to accurately reflect the actual performance of students.
[0004] In summary, there is an urgent need for an inclined body chin-up measurement device at present, which can more intuitively observe and measure the movements of students, so as to help improve the teaching and testing effects and improve the teaching and examination efficiency.

[0006] In order to achieve the above purpose, the technical scheme adopted by the utility model is:
[0007] An inclined body chin-up measurement device includes a right triangle main body, and one end of the hypotenuse of the right triangle main body extends; a vertical plate is provided on one right side of the right triangle main body, and the vertical plate is perpendicular to the right triangle main body for stably placing the right triangle main body.
[0008] Preferably, the right triangle main body is an isosceles right triangle.
[0009] Preferably, the vertical plates are symmetrically arranged on both sides of the right triangle main body and are fixedly connected to the right triangle main body.
[0010] Preferably, the vertical plate is a triangular structure and has the same height as the right triangle main body.

[0012] Preferably, the length of the hypotenuse of the right triangle body is 1.4m - 1.7m, and the length of the right side is 0.3m - 0.6m.
[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:
[0014] The right triangle body of this application is set as an isosceles right triangle. On this basis, the hypotenuse extends towards one end until the length is 1.4m - 1.7m. At the same time, vertical plates are provided on the right sides, and the vertical plates are symmetrically arranged on both sides of the right triangle body and are perpendicular to the right triangle body. When in use, place the measuring device of this application at the vertical pole of the horizontal bar, and the vertical plates can be aligned with the vertical pole of the horizontal bar. During the process of students doing inclined body pull-ups, by observing whether the inclination range of the student's body exceeds the hypotenuse of the right triangle body, that is, observing whether the inclination angle of the student's body is less than 45 degrees, to try to judge the standardization of the movement.

[0019] The following will describe the present utility model in detail with reference to the drawings.
[0020] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0021] Embodiment 1
[0022] An inclined body pull-up measuring device includes a right triangle main body 1, and the hypotenuse of the right triangle main body 1 extends towards one end; a vertical plate 2 is provided on one right side of the right triangle main body 1, and the vertical plate 2 is perpendicular to the right triangle main body 1 for stably placing the right triangle main body 1. The hypotenuse of the right triangle main body 1 extends towards one end. Preferably, it can extend to 1.4m - 1.7m. The vertical plate 2 is vertically arranged with the right triangle main body 1, and one side of the vertical plate 2 is flush with the other right side of the right triangle main body 1, so that the right triangle main body 1 can be placed at any position. Specifically, the right triangle main body 1 is an isosceles right triangle. That is, the two acute angles of the right triangle main body 1 are 45 degrees.
[0023] When this application is in use, place the right triangle main body 1 beside the single-pole vertical rod. Among them, the right side without the vertical plate 2 is in contact with the ground. When students do the inclined body pull-up project, with the help of the angle of the isosceles right triangle of this application, observe the inclination angle of the student's body. When the inclination angle of the student's body is greater than 45 degrees, the student's body is located between the bottom surface and the extension line of the hypotenuse. When the inclination angle of the student's body is less than 45 degrees, the student's body extends beyond the extension line of the hypotenuse. Since the hypotenuse of this application extends towards one end, during the test, the tester can more intuitively observe whether the test action is standard. At the same time, this application is provided with the vertical plate 2. When in use, the measuring device is placed more stably and can adjust the position of the measuring device according to the actual situation. The whole process helps to improve the teaching and test effects and improve the teaching and examination efficiency.
[0024] Specifically, the vertical plates 2 are symmetrically arranged on both sides of the right triangle main body 1 and are fixedly connected to the right triangle main body 1. The vertical plates 2 are symmetrically arranged on both sides of the right triangle main body 1, making the placement of the right triangle main body 1 more stable. At the same time, the vertical plates 2 and the right triangle main body 1 can be integrally formed, or can be connected by activities such as clamping, nut and bolt connection. When using the activity connection method, the vertical plates 2 can adapt to right triangle main bodies 1 of various specifications, saving costs.
[0025] Furthermore, the vertical plate 2 is a triangular structure and has the same height as the right triangle main body 1. The vertical plate 2 can also be set as a rectangular structure, etc. In this application, it is set as a triangular structure, and the longest side is aligned with the right side of the right triangle main body 1, and the structure is more stable. Among them, as long as the shape of the vertical plate 2 can achieve stable placement of the right triangle main body 1.
[0026] Further, the right triangle body 1 is a right triangle frame structure with a hollow middle. The hollow middle of the right triangle body 1 facilitates further observation of the inclination angle of the student's body during use.
[0027] Further, the hypotenuse length of the right triangle body 1 is 1.4 m - 1.7 m, and the right side length is 0.3 m - 0.6 m. The hypotenuse of the right triangle body 1 and the extended length are set to 1.4 m - 1.7 m. Preferably, it can be set to 1.5 m, and the right side length is set to 0.3 m - 0.6 m. Preferably, it is 0.4 m, which is more suitable for the body types of middle school students who sometimes need to do inclined body pull-ups.
[0028] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
