Exercise bicycle

Abstract

The invention discloses an exercise bicycle. The exercise bicycle comprises a supporting framework, and the supporting framework comprises a triangular frame which is formed by taking a connecting rod for connecting a front supporting leg and a rear supporting leg as a transverse rod, taking an inclined rod of the front supporting leg, a supporting frame of a treading device and a connecting block as an inclined rod and taking a seat stand column as a vertical rod and connecting three components together. The lower end of the inclined rod is fixed to the middle of a horizontal rod of the front supporting leg. The rear end of the connecting rod is fixed to the front side of the middle of a V-shaped rod which forms the rear supporting leg and is provided with a backward opening. A seat supporting device is installed at the top end of the seat stand column. A seat cushion supporting plate is arranged at the top of the seat stand column, a crank shifting device is installed at the front end of the seat cushion supporting plate, a positioning column matched with positioning holes is arranged on a shifting block of the crank shifting device, and a locking torsion spring for fastening the positioning column in one positioning hole is arranged on the crank shifting device. The supporting framework of the exercise bicycle is simple, compact and firm in structure and small in occupied area. The seat supporting device is firm in supporting and convenient to adjust front and back.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to an exercise bike. Background technique [0002] With people's new understanding and breakthroughs in the concept of fitness and work and study, it has become a possibility and reality to exercise while working or studying. For example, people sit on the seat of an exercise bike and step on the treadle of the exercise bike Working or studying while working has gradually become the norm. [0003] There are many types of exercise bikes in the prior art with different structures, but in actual use, the exercise bikes in the prior art still have the following deficiencies: 1. Some of the overall supporting frames of the exercise bike have complex structures, large volume, and occupy an area The area is large, some are too heavy and the material cost is high; some are slightly thin and not strong enough, and the durability is not good. 2. Some leg and foot support structure...

[0003] There are many types of exercise bikes in the prior art with different structures, but in actual use, the exercise bikes in the prior art still have the following deficiencies: 1. Some of the overall supporting frames of the exercise bike have complex structures, large volume, and occupy an area The area is large, some are too thick and heavy, and the material cost is high; some are slightly thin and not strong enough, and the durability is not good

2. Some leg and foot support structures of exercise bikes have complex structures and high material costs, while some leg and foot structures are relatively thin and have insufficient durability; the support legs are generally fixed structures, and the distance between the front and rear support legs cannot be adjusted; the support legs The structure of the foot pad is complex, the support is not strong enough, and it is inconvenient to disassemble and assemble

3. Some support devices for exercise bike seats are firm in structure, but slightly complicated; some are simple in structure, but inconvenient to adjust; The three are more difficult to unify and need to be improved urgently, and due to the l
