Horizontal bar and parallel bars for remote control teaching

Abstract

The invention discloses a horizontal bar and parallel bars for remote control teaching. A first supporting plate is welded to the top of a first support, a second supporting plate is welded to the top of a second support, the first supporting plate is connected with a first hollow column which is connected with a first locking rocker, the second supporting plate is connected with a second hollow column which is connected with a second locking rocker, a first conical balancing weight is connected with the first locking rocker through a first lifting screw, a second conical balancing weight is connected with the second locking rocker through a second lifting screw, the first locking rocker is connected with a first lifting motor and a first remote control receiver, the second locking rocker is connected with a second lifting motor and a second remote control receiver, and the second remote control receiver is electrically connected with the second lifting motor. The locking rockers are remotely controlled to adjust the balancing weights, so that the gravity center of the whole horizontal bar and parallel bars moves upward or downward to be suitable for different users, the users can take exercises stably in a balanced mode, and the teaching and exercising effect are better.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a single and double pole for remote control teaching suitable for students of different age groups. Background technique [0002] What often use in teaching equipment is horizontal bar and parallel bar. Among them, the skill of using the horizontal bar is simpler than that of the parallel bars, which is easy for students to master. In the teaching process, the horizontal bar is often used to do pull-ups. Pull-ups are a hanging strength exercise in which one's own strength overcomes one's own weight. It requires students to have certain grip strength, upper body strength and shoulder girdle strength. This strength must be able to overcome their own body weight to complete once. It plays an important role in the development of upper body hanging strength, shoulder girdle strength and grip strength. Pull-ups belong to pure upper body strength exercises, and the technic...

AI Technical Summary

Problems solved by technology

[0004] The single-parallel bar arm strength training equipment disclosed in this patent document has an unreasonable structural design. When the user needs to perform parallel bar exercise, both hands hold the handlebar connected to the force-applying mechanism, and the handlebar is subjected to the pressure exerted by the user and the user's own pressure. Gravity, combined with the user's body shaking during exercise, the resultant force received by the handlebars is transmitted to the base through the bracket, and the front and rear ends of the entire base are unevenly stressed, resulting in shaking, instability, and poor safety in use; Pedals are provided, and the user performs horizontal bar exercises by stepping on the pedals, and the front end of the base is further stressed, so that the force on the front end of the base is significantly greater than the force on the rear end of the base, further reducing the stability of the base; in addition, the single The parallel bar arm strength training equipment is relatively fixed, and the height cannot be adjusted, so it cannot be used by users of different heights
