Description

A hurdle device for middle school physical education teaching

technical field

The utility model belongs to physical education teaching equipment, in particular to a hurdle device for middle school physical education teaching.

Background technique

Hurdles is a sport that can improve the physical fitness of the practitioners such as speed, strength, coordination, flexibility, etc. In the physical education courses of various schools, hurdles are very common and popular among students. sports. But students are not professional athletes after all, and they are prone to collide with the railing or even knock down the railing when they are performing hurdle sports. It is easy to cause pain to the athlete, and even tripping and injury. Therefore, although hurdle sports are popular in physical education classes, especially middle school physical education classes, hurdle training is rarely really realized. It hinders middle school students' cognition and experience of hurdle projects. Therefore, it is the research purpose of the present utility model to design a hurdle device that can effectively alleviate the pain produced when bumping against the railing and prevent the hurdle device from tripping over the hurdle.

Contents of the invention

The utility model provides a hurdle device for physical education teaching in middle schools, which can effectively reduce the pain generated when bumping against a railing, and prevent tripping during hurdle movement.

The technical scheme of the utility model is as follows: a hurdle device for middle school physical education teaching, including a base, the two sides of the base are respectively fixed with corresponding hurdles, and the inner sides of the hurdles are respectively hinged with corresponding positioning rods. A railing is fixedly connected between the two positioning rods, and corresponding positioning holes are arranged on the inner side of the railing, and corresponding positioning sleeves are arranged in the positioning holes through a positioning spring device, and the outer ends of the positioning sleeves are set as Hemispherical, the positioning rod is provided with a corresponding hemispherical receiving groove at the position corresponding to the positioning sleeve, and the positioning rod is positioned on the corresponding railing through its receiving groove and the positioning sleeve on the railing On; the outer surface of the railing is covered with a corresponding rubber buffer layer.

The positioning sleeve is made of rubber material.

The utility model has the advantages: the inside of the hurdle frame of the utility model is provided with corresponding positioning holes, and the positioning holes have corresponding positioning sleeves through the positioning spring device, and the outer ends of the positioning sleeves are arranged in a semi-spherical shape. Corresponding positions are provided with corresponding hemispherical receiving grooves, and the positioning rods are positioned on the corresponding railings by cooperating with the positioning sleeves on the railings through the receiving slots. Once the student touches the railing, if the strength reaches a certain level, the positioning sleeve will be squeezed out of the corresponding receiving groove, and the positioning rod will rotate around its hinge point with the railing and fall down, preventing students from falling and reducing pain . Since the outer end of the positioning sleeve is set in a semi-spherical shape, any jamming will not occur when it enters and exits the accommodating groove, which effectively ensures the safety and stability of the utility model. If the strength of the student touches the railing is small, the positioning sleeve will not be squeezed out of the corresponding accommodating groove. Due to the small touch force, the pain caused when the student hits the railing will not be too much due to the effect of the rubber buffer layer. Big. For the purpose of safety and protecting students, the utility model is suitable to be popularized in middle school physical education teaching.

detailed description

For the convenience of those skilled in the art to understand, the structure of the present utility model will be further described in detail with the embodiment in conjunction with the accompanying drawings:

Referring to Figures 1-3, a hurdle device for middle school physical education teaching includes a base 1, and corresponding hurdles 2 are fixedly connected to both sides of the base 1, and corresponding positioning rods are respectively hinged on the inner sides of the hurdles 2. 3. A railing 4 is fixedly connected between the two positioning rods 3, and corresponding positioning holes are provided on the inside of the railing 2, and corresponding positioning sleeves 6 are installed in the positioning holes through the positioning spring 5, so that The outer end of the positioning sleeve 6 is arranged in a semi-spherical shape, and the positioning rod 3 is provided with a corresponding semi-spherical receiving groove at a position corresponding to the positioning sleeve 6, and the positioning rod 3 is connected with the rail by its receiving groove The positioning sleeve 6 on the frame 2 is matched and positioned on the corresponding railing 2; the outer surface of the railing 4 is covered with a layer of corresponding rubber buffer layer 7 . The positioning sleeve 6 is made of rubber material.

Once the student touches the railing 4, if the strength reaches a certain level, the positioning sleeve 6 is squeezed out of the corresponding receiving groove, and the positioning rod 3 rotates around its hinge point with the railing 2 and falls down to prevent the student from falling. Also relieve pain. Since the outer end of the positioning sleeve 6 is set in a semi-spherical shape, it will not get stuck when entering and leaving the receiving groove, which effectively ensures the safety and stability of the utility model. If the strength of the student touching the railing 4 is small, the positioning sleeve 6 will not be extruded out of the corresponding receiving groove. Because the touching force is small, the pain generated when the rubber buffer layer 7 hits the railing will not be affected. will be too big.

The above descriptions are only preferred embodiments of the present utility model, and all equal changes and modifications made according to the patent scope of the present utility model shall fall within the scope of the present utility model.
