Abstract

The utility model discloses an outdoor exercise bike which comprises a car frame with a seat. A universal wheel is arranged on the front portion of the car frame to be a front wheel, and back wheels are respectively arranged on the left side and the right side of the back portion of the car frame. The back wheels are driven by a driving device. The driving device comprises a power shaft, a first winch and a second winch, wherein the power shaft is connected with the back wheels, the first winch is arranged on the power shaft, and the second winch is arranged on the middle-rear portion of the car frame and the front portion of the power shaft. A one-way clutch is arranged between the first winch and the power shaft. A steel wire is arranged between the first winch and the second winch. The first winch and the second winch can rotate by mutually driving. Pull arms are arranged on the two sides of the car frame, and the lower end of the pull arms are connected with a transmission shaft of the second winch. The outdoor exercise bike has the advantages of being compact and simple in structure and capable of enabling the bicycle to move at the same time when users are exercising. Therefore, the users not only can exercise but also can appreciate scenery around, accordingly drab feeling is reduced. Besides, the outdoor exercise bike has the advantage of enabling the users to use their hands to repeatedly push a bike to drive, thereby exercising the muscle of waists, backs , arms of the users.

Description

A kind of outdoor body-building bicycle

Technical field

The utility model relates to a kind of body-building apparatus.

Background technology

Along with improving constantly of socioeconomic high speed development and people's living standard, amusement and recreation have become the modern people requisite important life part after the leisure of working.But there are many shortcomings in existing recreation entertainment equipment, as important recreation and body-building instrument: bicycle, just there is safety, comfortable, the laborsaving uncompatibility that waits aspect of performance, the speed of ordinary bicycle is low, effort and comfort level are poor to be a larger problem., by human factor engineering research as can be known, the vehicle seat of ordinary bicycle is narrow, be narrow triangle, impact is action to pedal, especially mountain bike, sport car, the vehicle seat of racing car is narrower, just more lacks comfort, so that the purpose of driver's fatiguability out of reach amusement and recreation, it is single, dry as dust that simultaneously a lot of indoor amusement and recreation body-building equipments exist environment, can not reach the purpose of joyful psychosoma.

The utility model content

The purpose of this utility model is to provide a kind of outdoor body-building bicycle of tempering arm.

To achieve these goals, by the following technical solutions: a kind of outdoor body-building bicycle, comprise the vehicle frame with seat, the vehicle frame front portion is provided with cardan wheel as front-wheel, the rear portion of vehicle frame each side is provided with trailing wheel, trailing wheel is driven by actuating device, it is characterized in that: described actuating device comprises: the dynamical axis that is connected with trailing wheel, be arranged on the first capstan winch on the dynamical axis, be provided with free-wheel clutch between the first capstan winch and the dynamical axis, be arranged on the vehicle frame postmedian, the second capstan winch of dynamical axis front portion, be wound with steel cable between the second capstan winch and the first capstan winch, can mutually drive rotation, the both sides of vehicle frame are provided with torque arm, and the lower end of torque arm links to each other with the transmission shaft of the second capstan winch.

For convenient control brake and controlling party to, the top of described torque arm is provided with brake handle, is provided with brake disc on the trailing wheel, by brake handle brake disc is controlled, described brake handle and corresponding brake disc are two covers, and brake handle is divided in two torque arm that are positioned at both sides.

The utility model compact conformation is simple, and bicycle can move simultaneously when taking exercise, and has both tempered health, can appreciate scenery on every side again, reduces the dullness sense of taking exercise.Make with the hands reciprocating torque arm drive bicycle running, effectively waist, back and the muscles of the arm of training of human.

Description of drawings

Fig. 1 is the structural representation of utility model embodiment;

Fig. 2 is the utility model embodiment block diagram;

Fig. 3 is the left view of Fig. 1.

Among the figure, 1 is seat, and 2 are torque arm, and 3 is brake handle, and 4 is vehicle frame, and 5 is cardan wheel, and 6 is trailing wheel, and 7 is brake disc, and 8 is free-wheel clutch, and 9 is the first capstan winch, and 10 is steel cable, and 11 is the second capstan winch, and 12 is dynamical axis, and 13 is transmission shaft, and 14 are the torque arm handle.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described further.

As shown in Figure 1 and Figure 2, a kind of outdoor body-building bicycle comprises that vehicle frame 4 vehicle frame front portions are provided with cardan wheel 5 as front-wheel, and the vehicle frame middle part is provided with seat 1, and the rear portion is provided with trailing wheel 6 and actuating device.

Such as Fig. 2, shown in Figure 3, the actuating device of bicycle is comprised of dynamical axis 12, free-wheel clutch 8, the first capstan winch 9, the second capstan winch 11, steel cable 10, dynamical axis 12 and torque arm 2, wherein, dynamical axis 12 1 ends are connected with trailing wheel 6, the other end is connected with free-wheel clutch 8, and the free-wheel clutch outer setting has the first capstan winch 9, the first capstan winches 9 to be connected with the second capstan winch 11 by steel cable 14, the second capstan winch 11 is connected with the transmission shaft 13 that is arranged on the vehicle frame middle part, and transmission shaft 13 is connected with the torque arm 2 of vehicle frame outside.

As shown in Figure 1, brake handle 3 is arranged on torque arm 2 tops, and trailing wheel 6 is provided with brake disc 7, is provided with brake handle two torque arm, controls respectively the brake to two trailing wheels.

During work, both hands alternately or spur simultaneously torque arm handle 14 back and forth movements, drive 11 rotations of the second capstan winch, the second capstan winch 11 passes to the first capstan winch 9 by steel cable 10 with power, the first capstan winch 9 drives free-wheel clutch 8, dynamical axis 12, trailing wheel 6 rotations, move ahead waist and the muscles of the arm of effective training of human when the driving car moves ahead thereby drive vehicle.When travelling, can turn to by brake: during left-hand rotation, draw left brake handle; During right-hand rotation, draw right brake handle.
