Physical training device for physical education

Abstract

The invention belongs to the technical field of physical training, and particularly relates to a physical training device for physical education, which comprises a bottom frame, the top of the bottomframe is fixedly connected with a vertical frame; a group of guide pulleys are arranged at the top of the vertical frame; a steel rope is arranged on the guide pulleys; a pull rod is arranged at one end of the steel rope, and an adjusting rod is arranged at the other end of the steel rope; a set of sliding holes are formed in the bottom of a balancing weight, sliding columns are slidably connectedinto the sliding holes, and springs are fixedly connected between the sliding columns and the bottoms of the sliding holes. The bottom of each sliding column extends out of the balancing weight, anda rubber pad is fixedly connected to the bottom of the sliding column. The depth of the sliding holes is larger than the sum of the lengths of the sliding column sand the rubber pads. An exhaust holeis formed in the bottom of each sliding hole, and the diameter of the exhaust hole is smaller than one fifth of that of the sliding hole; the speed of the balancing weight is reduced through the sliding columns, and damage to the training device is reduced.

Description

technical field [0001] The invention belongs to the technical field of physical training, in particular to a physical training device for physical education teaching. Background technique [0002] According to the performance and function of physical fitness in different groups of people, physical fitness can be divided into two levels: healthy physical fitness and competitive physical fitness. Healthy physical fitness refers to the functional capabilities of organ systems necessary for any group of people. On the basis of healthy physical fitness, the physical function ability required for further development of competitive competitions, the development of athletes' competitive physical fitness is affected by many factors, congenital physical fitness is obtained through genetic effects, acquired physical fitness is mainly through effective At the same time, it can also be developed in a suitable geographical environment and a good social environment. The direct task of phys...

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, it is easy to cause the adjustment rod and the counterweight to fall rapidly when the tie rod is loosened or the speed of the tie rod rises too fast in the prior art, which in turn causes the counterweight to hit violently, resulting in huge noise , leading to the problem of damage to the training device in severe cases, a physical training device for physical education proposed by the present invention
