Abstract

The utility model discloses a backstroke simulation fitness device, which comprises several parts such as a supporting device for a human body, a sliding device for an arm, and a moving device for a leg. Among them, the sliding of the arm is one of the power sources. The swing of the hand in the air drives the front axle to rotate, and the cross motion of the two cams on the front axle will realize the up and down movement of the deck. The front axle transmits the movement to the rear crankshaft through gear meshing, and the crankshaft drives the legs to move up and down. The feet are provided with elastic devices, so that the exerciser can realize the consistent movement of hands and feet during exercise, so as to exercise the muscles of the whole body. With the help of simulated swimming movements, the dual purpose of fitness and swimming learning can be achieved.

Description

Backstroke Simulator

technical field

The utility model relates to the fields of machinery, fitness and entertainment, and provides a backstroke simulation fitness device, which is mainly used in community fitness and entertainment.

Background technique

With the progress of the times and the development of society, more and more people begin to pay attention to improving the quality of life and strengthening their bodies, so more and more people choose to use their spare time for physical exercise. Fitness equipment is aimed at the muscle exercise of a certain part of the human body, and there are only a few of them that can exercise all the muscles of the body. Among all kinds of sports, swimming is relatively the most comprehensive exercise for exercising the body parts. The effect of exercise is the most obvious, and it is generally suitable for any age. The realization of general swimming postures must go to specific places such as swimming pools and swimming pools, so not everyone has a reasonable time and a reasonable place to swim and exercise, and there is generally no swimming pool in the gym, which cannot achieve the dual effects of swimming and fitness At the same time, it is difficult for people who cannot swim to achieve the same exercise effect. The utility model is a kind of body-building equipment designed based on this background. This body-building machine can realize the swimming posture on land so as to achieve the purpose of exercising the body.

Through retrieval, disclose a kind of swimming fitness equipment as Chinese patent (authorized announcement number is CN 2263535Y), the purpose of this fitness equipment is to realize people's swimming action by pulling rope, overall structure is not compact, and the utility model is structurally more Compact, it can realize the coordinated movement of hands and feet, and can perform a more realistic simulation of backstroke.

Contents of the invention

In order to overcome the deficiency that the existing fitness equipment can only exercise a certain part of the body, the utility model provides a swimming fitness equipment that can exercise all parts of the whole body. Completing the swimming action on this equipment can also achieve the exercise for the muscles of the whole body.

The solution adopted by the utility model to solve its technical problems is: the backstroke swimming fitness equipment includes three parts: a driving component, a transmission component and a moving component, and its feature is that the driving arm is placed on both sides of the lying board and The front axle is connected, and the driving arm is equipped with a handle bar and a handle bar. The user can adjust the handle bar according to the length of his arm to achieve the most comfortable level for himself. When the arm moves in space, the universal hinge drives the front shaft to rotate, and when the front shaft rotates, it will drive the two cams on the shaft and the gear mechanism to rotate together. Because the two cams on the front axle are arranged crosswise, when the axle moves, the cam on the axle will drive the lying board to turn up and down, so as to achieve the purpose of exercising the waist muscles of people; through the meshing of the gears, the front axle will drive the back When the crankshaft rotates, the crankshaft drives the leg device to move up and down, so as to exercise the human leg. In order to be suitable for people of different heights, the length of the leg parts can also be adjusted. People can adjust their length according to the length of their own legs to achieve the most comfortable level, and then fix them by pins. The legs and the feet are connected to each other through elastic parts, which can not only realize the synchronous movement of the hands and feet, but also achieve the purpose of exercising the ankle joints of the feet at the same time, and achieve the exercise of the muscles of the whole body through the fitness equipment.

The utility model has the following effects through the above-mentioned technical scheme: when a person lies flat on the support plate, with the rotation of the arm, the universal hinge converts its motion into the rotation of the front axle, and the front axle will drive the two cams on it The mechanism realizes the cross movement, and the support plate on the cam will turn up and down; the rotation of the front wheel is transmitted to the rear crankshaft through the meshing of the gears to realize the rotation of the crankshaft, and the crankshaft drives the foot joint to move up and down; the connection between the foot and the foot joint They are connected to each other through elastic elements, so that the active movement of the feet can be practiced, and the coordinated movement of the hands and feet can be realized. The utility model can finally realize the exercise of the whole body.

The backstroke swimming device described above uses the mutual meshing of gears for transmission to realize accurate transmission, and a rolling bearing is added to the rotating member, which eliminates the contact damage of the parts and improves the transmission efficiency; the fitness device has many exercise parts, low noise The advantages of small size, compact structure, high efficiency and large carrying capacity can be used in residential areas or gyms, especially in the field of fitness. The utility model has the advantages of simple structure and convenient use, and can provide a kind of practice on land for people who can swim, so that they can quickly grasp the essentials and learn to swim, and people who can't swim can get the purpose of exercise and practice harder.

The utility model is described in detail below in conjunction with accompanying drawing.

Detailed ways

The concrete embodiment of the present utility model is: the main support of this swimming fitness equipment is support base 15, and its supporting integral part, on support frame 15, recliner 2 is housed, and support base 15 and recliner 2 are mutually connected by rotating shaft 26 . During exercise, people put their arms into the handle rings 4 on both sides of the reclining board 2, and adjust the length through the handle bar 3 to reach their most comfortable level. After the length is adjusted, the arm can be exercised through circular motion through the arm space. The universal hinge 20 transmits the motion of the arm to the front shaft 24, and the front shaft 24 drives two cross-arranged cams 21 to realize circular motion, which will drive The upper deck 2 realizes its up-and-down movement around the rotating shaft 26, thereby reaching the purpose of exercising people's waist muscles. In order to prevent people from falling off when exercising, guardrails 6 are installed on both sides of the deck. In order to avoid the dry friction between the cam 21 and the upper deck, the utility model will be equipped with a rolling bearing 23 at the connection with the cam mechanism. Small loss of energy. Through the mutual meshing of the gear 22 and the gear 25, the front axle 25 transmits the motion to the crankshaft 24 at the back, and the crankshaft 24 drives the legs to move up and down, so that the leg muscles can be exercised. In order to adapt to the leg lengths of different people, the upper transmission rod 12 and the lower transmission rod 13 of the feet can be adjusted to each other, and the pedal 10 and the lower transmission rod 13 are connected to each other by elastic parts 9, which can be well exercised. People's ankles can also realize the coordinated movement of hands and feet, which achieves a relatively ideal effect on people's physical exercise.

The above-mentioned examples are only to illustrate the technical conception and characteristics of the present utility model. Equivalent changes or modifications made by the spirit of the utility model shall fall within the protection scope of the utility model.
