Multifunctional combined instrument for physical education practice

Abstract

The invention relates to the technical field of physical education instruments, and discloses a multifunctional combined instrument for physical education practice. The instrument includes a fixed bottom plate, a sliding groove is formed in the middle of the upper end of the fixed bottom plate. A sliding plate is slidably arranged in the sliding groove. A fixed cylinder is mounted at the upper endof sliding plate, the top of the fixed cylinder is connected with a lifting cylinder through fixed springs; a driving cylinder is mounted at the top of the lifting cylinder; a driving lead screw is mounted in the driving cylinder; a lifting block is mounted in the middle of the driving screw through a thread structure; stretching rods are hinged to the two ends of the lifting block, rollers are installed at the top ends of the stretching rods and slidably arranged in rolling grooves below rotating plates hinged to the two ends of a fixed block, the fixed block is fixed to the top end of the driving cylinder, a balance plate is installed between the top ends of the rotating plates, and a supporting frame is installed on the right side of the upper end of the fixed bottom plate, and a traction frame is arranged on the upper end of the supporting frame. According to the instrument, the adjustment of the vertical height of the balance plate is ensured, the requirements of sit-ups with different heights and bends are met, and the functionality of the instrument is further improved.

Description

technical field [0001] The invention relates to the technical field of physical education teaching equipment, in particular to a multifunctional combination equipment for physical education teaching and practice. Background technique [0002] Sports equipment refers to the general term for various equipment, equipment and supplies used in competitive sports competitions and fitness exercises. Sports equipment and sports are interdependent and promote each other. The popularization of sports and the diversification of sports make the types and specifications of sports equipment develop. With the development of society, people pay more and more attention to sports, and the demand for sports equipment is also increasing. The physical education course is a public compulsory course for students to use physical exercises as the main means, through reasonable physical education and scientific physical exercise process, to achieve the main goals of strengthening physical fitness, ...

Problems solved by technology

[0003] At present, the general sports equipment has a single function and a simple structure. When performing physical exercise or physical education, it often requires the assistance of others or multiple sports equipment for various physical exercises, which cannot meet the needs of multiple sports training in physical education exercises.

[0004] Chinese patent (Notice No.: CN111001125A) discloses a multifunctional combination equipment for physical education teaching and practice, including a support frame, and electric lifting rods are provided at the left and right ends of the upper surface of the supporting frame, and the electric lifting rods There is a lift switch on the side of the lift switch, the input end of the lift switch is electrically connected to the output end of the external power supply, the output end of the lift switch is electrically connected to the input end of the electric lift rod, and the top of the electric lift rod is provided with a fixed A support bar is provided between the two fixed blocks. A semicircular notch is provided on the upper surface of the fixed block. A barbell is placed in the semicircular notch. The two ends of the board are slidingly connected. Although the above-mentioned device can achieve the purpose of combined teaching in actual teaching, the applicability is poor in the process of use. Students cannot perform the purpose of pre-exercise before physical exercise, and at the same time perform sit-ups The height and angle cannot be adjusted, therefore, further improvement is needed
