Description
Technical Field
The invention relates to a multifunctional crawling machine and an installation method thereof, and belongs to the technical field of sports fitness equipment.
Background
Crawling, i.e. the cooperation of both arms supporting the ground and both feet, forms the action of reciprocal crawling of the limbs, which is called "return to ancestor" action. For adults, the crawling can disperse the whole weight of the spine to four limbs so as to lighten the load of each part of the body, particularly the lumbar, and restore the whole spine to a physiological state. Therefore, the medicine has better curative effect on lumbar disc herniation patients, lumbar muscle strain and various cervical, shoulder and spinal diseases. When a human body is upright, the gravity influence of blood is overcome to promote blood circulation by the heart. When a person moves upright, the lower limbs are the main moving organs, blood is distributed to the lower limbs more, and the blood supply of the heart and the organs above the heart is reduced. Compared with the prior art, the heart and the parts above the heart are reduced during crawling, so that the heart-blood circulation is facilitated, and the heart-blood circulation-promoting and heart-blood circulation-promoting device has a positive effect on preventing and treating cardiovascular diseases.
Along with popularization and promotion of the national fitness sports, more and more crawling sports enthusiasts are provided, and due to the limitation of fields and equipment, most people want to participate in the fitness sports but cannot pay for the sports, and only can be used as visitors. If the crawling exercise is carried out in a public place, certain courage is really needed, because the crawling exercise is another type of body building and is often regarded as an 'inelegant' action, many people can be aroused in curiosity and sidedness, and the crawling exercise needs to wear knee pads and gloves when people climb on a hard ground, so that most crawling sports enthusiasts insist on taking exercises indoors, and the exercise is very inconvenient and difficult to receive good exercise effects due to the fact that the indoor field is small.
At present, various treadmills are generally installed in families, are suitable for running and walking exercises, and move forward alternately on a pedal by two feet, and because the two feet are always alternately pedaled on the same running belt, the two feet continuously generate friction thrust on the running belt under the unpowered condition, so that the speed of the running belt is difficult to control, an electric control system is installed at present; however, the crawling action is the landing of both palms and both feet, the action is the interactive forward movement of the limbs, and the action, the amplitude, the frequency and the speed are completely different compared with the running. When in crawling, the feet and the hands on the left side and the right side move forwards alternately, and the feet and the hands on the same side move forwards alternately, particularly, the feet and the hands on one side move relatively to the feet and the hands on the other side in the crawling process, for example: when the foot and the hand on the right side move, the foot and the hand on the left side are relatively static; the foot and the hand on the same side move relatively, the foot is firstly actively pedaled and then moves forwards, and the hand is passively matched with the movement of the foot and moves forwards synchronously; in view of the fact that the currently used running machine only has one running belt, the running machine is suitable for double feet to alternately move forward at a fast pace under the condition of electric power, is not suitable for four limbs to alternately crawl at a slow pace, and is easy to fall down even if the running machine is driven by manpower to crawl, namely the running machine is provided with the electric power speed regulator.
Therefore, at present, a crawling machine is lacked, in particular to a multifunctional crawling machine which is suitable for crawling and running under the condition of no electric power, the crawling machine is provided with two pairs of running belts which are symmetrically arranged front and back and left and right, each running belt and a transmission device of each running belt are working units which have the same structure and run independently, crawling exercise can be carried out under the condition of no electric power assistance, and the crawling machine is suitable for people of different age stages and constitutions to use, one of the crawling machine is that the four limbs of a body drive the driving belts to crawl when crawling, the crawling machine is closer to the real scene on the ground, and the four driving belts working independently correspond to two palms and two feet, so that each palm and each foot can be relatively static or move under the condition of not being interfered by external force; the crawling machine has the advantages that after the upper handrails, the supporting legs and the partition plates are additionally arranged at the front end and the rear end of the running platform, the running platform can be used as a double-person running machine no matter in a horizontal state or in an inclined state after being bent, the running surface is suitable for middle-aged and elderly people and women to exercise in the horizontal state, and the crawling machine is suitable for young and old people to exercise in the inclined state and solves the problems of high cost and large occupied space of repeated purchase of running machines; the utility model has the advantages of the third is that this machine of crawling running platform, beautiful jade wheel, handrail frame, baffle and pivot all can freely install and dismantle, and running platform is collapsible moreover, is convenient for transport, carry, store, installation and dismantlement, and storage space is little, low in manufacturing cost, suitable ordinary family uses.
