A high-tension back muscle trainer based on physical education teaching

Abstract

The invention discloses a high-tension back muscle training device based on physical education teaching, relates to the technical field of back muscle training devices, and solves the problem that the existing back muscle training device needs to frequently sit up to adjust the counterweight when adjusting the counterweight The weight of the block, and there is a certain danger to the device and personnel after the pull rod is released. A high-tension back muscle training device based on physical education, including an adjustment mechanism and a protection mechanism; the adjustment mechanism is composed of an adjustment gear, a transmission gear, a wire hub, a support rod and an adjustment rod. The adjustment mechanism of the device can adjust the pulling force used to pull the same counterweight within a certain range by turning the adjustment lever while sitting on the training bench without adjusting the counterweight, without frequent sitting ups , and the device can avoid the occurrence of damage to the device and danger to the personnel present through the protection mechanism that the trainer's hand slips or exhaustion causes the training handle to drop, causing the weight box to fall rapidly and impact.

Description

technical field [0001] The invention belongs to the technical field of back muscle trainers, and more specifically relates to a high-tension back muscle trainer based on physical education teaching. Background technique [0002] In recent years, with the progress of the society, people's living standards are also gradually changing. Although the living standards have improved, people's work pressure is also increasing. Some students usually study and work for a long time, and often maintain The same sitting posture, coupled with incorrect posture and heavy work intensity, will inevitably cause back muscle pain, muscle fatigue, and then cause low back pain. In severe cases, it may cause symptoms such as low back muscle strain and lumbar disc herniation. [0003] The high-tension back muscle trainer mainly exercises the latissimus dorsi, trapezius, deltoid and biceps, which can improve the strength of the back muscles of the body, enhance the stretching force of the back muscl...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a high-tension back muscle training device based on physical education, to solve the problem that when the existing back muscle training device is in use, people sit on the training bench of the back muscle training device and pull it vertically The pull rod lifts the counterweight on one side of the back muscle trainer through transmission to achieve the purpose of training the back muscles. Due to the need for sitting training, when it is necessary to adjust the weight of the counterweight to achieve your own appropriate training intensity, you need to It is very inconvenient to adjust the weight of the counterweight by sitting up frequently, which cannot be fine-tuned, and the existing back muscle trainer has no protection device for the device and personnel. Generally, beginners need to use it under the guidance of professional instructors, otherwise It is prone to hand slipping or exhaustion, causing the pull rod to fall off, causing the weight of the back muscle trainer to fall quickly, smashing the device or the personnel present, which poses a certain danger to the device and personnel, and the problem of low practicability
