Auxiliary stretching training device for arm strength training of sports students

Abstract

The invention belongs to the technical field of stretching training, and discloses an auxiliary stretching training device for arm strength training for sports, which comprises a base, a bottom plate is fixedly mounted at the right end of the top of the base, and two supporting plates are fixedly mounted at the top of the bottom plate. A vertical block located between the two supporting plates is fixedly installed at the top of the bottom plate, a weight is movably connected into the vertical block in a sleeved mode, and a vertical rod is fixedly installed at the top of the weight. When a sportsman cannot exert large strength, the sportsman can also conduct back-and-forth stretching movement of muscles under the condition that the sportsman does not exert large strength by slowly pulling the heavy object to ascend, and compared with a traditional device, the device can conduct back-and-forth stretching movement according to the pulling force exerted on the pull handle during real-time training of the sportsman. And the corresponding counter-acting force is applied, so that the training effect is improved, and meanwhile, the muscle strain can be prevented.

Description

technical field [0001] The invention belongs to the technical field of stretching training, in particular to an auxiliary stretching training device used for arm strength training of sports students. Background technique [0002] Physical education uses physical and intellectual activities as the basic means, according to the laws of human growth and development, skill formation and function improvement, to promote overall development, improve physical quality and comprehensive education level, enhance physical fitness and improve athletic ability, improve lifestyle and improve life. A conscious, purposeful and organized activity of quality, physical exercise can make the body strong, and can cultivate virtues such as bravery, resourcefulness and safeguarding collective interests, and arm strength training is one of the most common sports, outdoor training venues It is equipped with various types of sports training equipment. The tension trainer is a commonly used muscle tra...

Problems solved by technology

[0003]At present, when sports students are performing high-intensity muscle training, they usually need to use arm stretching training devices for daily muscle training, but general arm strength training In order to train the arm strength of different strengths, the auxiliary stretching training device can usually manually adjust the weight of the load. However, after a long period of continuous training, the arm muscles will be sore. At this time, due to the traditional training The device cannot automatically assist or reduce the weight of the actual situation of the sports students during training, so that the training effect of the sports students is poor and it is easy to cause muscle strain after reaching the training limit, which brings inconvenience to the training of sports students

[0004] When the sports students use the auxiliary stretching training device for arm training, when the continuous training time is long, and the sports students' hands are injured due to strenuous exercise A lot of sweat is produced, which makes it easy for the gym students to separate from the pull rod, causing the weight inside the auxiliary stretch training device for arm strength training to fall, thereby colliding violently with the bottom of the device. The stretching training device causes certain damage, which reduces the life of the device. At the same time, the inertia is large when it is dropped. After hitting the bottom of the device, there will be a harsh impact sound, which will affect the normal training of other sports students.

[0005] When the auxiliary stretch training device for general arm strength training is used, because the price of the training equipment is relatively expensive, the number of times the equipment is used is relatively frequent. The continuous use of raw materials will cause the internal weight to perform hundreds of times of reciprocating movement, and generate dynamic friction with the inside of the device. Due to the existence of friction, the contact surface between the weight and the device will generate a higher temperature, thus Exacerbating the degree of wear of the heavy objects, reducing the service life of the device, and at the same time due to the wear of the heavy objects, the frequency of replacement of the heavy objects increases, so it needs to be improved and optimized
