Description

A pedal swing type recreational exercise bike

Technical field:

The invention relates to a pedal swing type entertainment exercise bike, which belongs to the field of leisure entertainment and exercise fitness equipment.

Background technique:

In recent years, with the sustained and rapid development of our country's economy, people's living standards have continued to improve. From the lack of food in the past to the well-off society today, there has been a huge change, and there are also some problems in this change. In the "Report on Nutrition and Chronic Disease Status of Chinese Residents (2015)" issued by the National Health and Family Planning Commission, it is mentioned that the overweight and obesity rates of Chinese residents in 2015 have a relatively obvious upward trend compared with 10 years ago. There are also some people around me who are a bit overweight or even obese. There are many reasons for this. One of the important reasons is that they eat better but lack exercise. The reason: on the one hand, it is because exercising is relatively hard, and some people cannot bear it; on the other hand, most of the current fitness equipment is fixed, and it is more common in community squares or gyms. Although people can choose to exercise here, they always Faced with the same environment, people gradually lose interest in exercising over time.

A healthy body is what everyone yearns for. Exercise is an important way to get healthy. It is more convenient and casual to use outdoor fitness scooters. People can exercise on the way to work and school, or in communities and squares. The process of fitness has also become more leisurely, and the field of vision has become vast, which also enables the bodybuilders to enjoy the natural scenery while exercising, and experience the fun of fitness without knowing it. In this way, people will be more willing to exercise, enhance their physical fitness, and at the same time relax their minds.

Invention content:

The object of the present invention is to provide an outdoor pedal swing type recreational exercise bike, which can replace bicycles as a vehicle for traveling, and can also be used for entertainment and fitness in outdoor venues such as squares and playgrounds.

The present invention achieves the above object through the following technical solutions.

Pedal swing type entertainment exercise bike is composed of frame, front bracket, rear suspension, pedal device, ratchet mechanism, transmission system, brake device, folding device, front and rear wheels, etc. Left and right pedals are installed on the frame One for each, a ratchet mechanism is installed under the pedals, the pedals drive the transition link to move up and down, the transition link pushes the rocker to swing, and then the ratchet on the rocker pushes the ratchet to rotate a certain angle, when the pedal resets under the action of the torsion spring , the other pedal is in the depressed state, and the power transmission is realized through another set of ratchet mechanisms, and the continuous driving force is realized through the alternate work of the two sets of ratchet mechanisms; in order to achieve the purpose of labor-saving and speed-up, the transmission system is driven by two-stage cylindrical spur gears. Composed of a first-stage chain transmission, the power is transmitted to the rear wheel by the transmission system; the rear wheel is installed on the rear suspension through the hub, and the rear suspension is connected to the rear of the frame through bolts; the front bracket is installed on the front of the frame through a pin connection. The height can be freely telescopically adjusted, and can be folded, and a handle and a brake device are installed on the front bracket.

Compared with the existing exercise bike, the present invention has the following characteristics: the bodybuilder stands up and down and alternately steps on the pedals, the whole body can be effectively exercised, and the fitness effect is better; when not in use, the front bracket can be folded toward the body to make the storage space It occupies a smaller area; the speed is achieved through two-stage gear transmission and one-stage chain transmission, and the speed-up effect is obvious. The maximum speed can reach 15 km/h (the diameter of the wheel is 12 inches), and it can replace bicycles as a means of travel.

detailed description:

Referring to Fig. 1 to Fig. 4, these 4 accompanying drawings provide the structural diagram of an embodiment of the pedal swing type recreational exercise car proposed by the present invention, it is characterized in that: comprise vehicle frame, front bracket, rear suspension, pedal device , ratchet mechanism, transmission system, braking device, folding device, front and rear wheels, left and right pedals (11) are installed on the vehicle frame (9) through pins and torsion springs (13), and a transition is installed below the pedals (11) Connecting rod (12) and rocking bar (43), ratchet (50) is connected on the rocking bar (43) by pin and back-moving spring (48); Transmission system is made up of two-stage gear transmission and one-stage chain transmission, main parts Made up of some gears (26,40,51), sprockets (37,38), shafts (24,29,31) and bearings (28), the bearings (28) are installed in the bearing housing (25), and the bearing housing ( 25) Install on the left and right sides of the vehicle frame through bolt connection; the front and rear wheels (18, 1) are installed on the front and rear axles (22, 35) through hubs (21, 34), and the rear axle (35) is installed on the rear On the suspension (4), the rear suspension (4) is connected to the rear of the vehicle frame (1) by bolts, the front wheel shaft (22) is installed on the front bracket (17), and the front bracket (17) is connected by the pin (14) and the spring (15) is installed on the crotch of vehicle frame (1) front portion, and brake handle (16) and brake line are installed on the front support upper end handlebar.

The original power of the pedal swing fitness scooter is provided by people. When using the exercise bike, the bodybuilder holds the handlebars with both hands, and alternately steps on the pedals with both feet to form power to drive the ratchet wheel to rotate, and then transmit the power to the scooter through a series of transmission systems. rear wheel, thereby realizing the forward movement of the exercise bike. Because the ratchet mechanism has a certain space, so when using the scooter, it needs to be pushed first to give the scooter an initial speed. After using the exercise bike, toggle the pin connected to the spring to make the front bracket move down along the arc-shaped guide rail of the hook at the front of the frame, and at the same time drive the handlebar to approach the frame to complete the folding function.

Pedal swing recreational exercise bike is different from other sports and fitness equipment. It can not only replace bicycles as a means of transportation, but also can be used for outdoor fitness, allowing users to get exercise while riding, and it is also entertaining, allowing users to Experience the fun of riding from time to time, and exercise your body unconsciously.
