Pedal hand-pulled bicycle

Abstract

The invention belongs to the technical field of the bicycle and relates to a pedal hand-pulled bicycle. The pedal hand-pulled bicycle is characterized in that the lower part of a handle upright casing is welded with the periphery of one side of a bearing; an upper stop-gear and a lower stop-gear are separately connected with a front fork shaft; the two sides of a connection steel plate between the upper stop-gear and the lower stop-gear are separately welded with the sides of two U-shaped hooks; the bearing is arranged between the U-shaped hooks, the both ends of the bearing shaft extend out of the U-shaped hooks and are fastened and connected by nuts; the lower end of the handle upright casing is connected with a radius-changing rod through a stay; and one end of the stay is connected with the endpoint of the radius-changing rod, and the other end is fixedly connected with and wound in the rim groove of a coil spring assembly through a guide wheel and the coil spring assembly. The invention has the following beneficial effect that when riding the bicycle, the rider pulls the handle; the handle upright casing can rotate around the bearing shaft in the limit range of the upper and lower stop-gears; and the bearing and the U-shaped hooks are integrated with the front fork shaft through the upper and lower stop-gears, thus the bicycle can operate flexibly at a corner and have no hidden danger. Compared with the existing bicycle, the pedal hand-pulled bicycle has lower production cost.

Description

technical field [0001] The invention belongs to the technical field of bicycles, and relates to a pedal and hand-pulled bicycle, in particular to the improvement of the steering mechanism of the Chinese patent No. 200720001556.8, which is called a pedal and hand-pulled bicycle. Background technique [0002] Bicycle is the means of transportation and body-building tool commonly used by people, and has many advantages such as environmental protection, pollution-free, and easy to use. However, it still feels strenuous during long-distance travel, riding against the wind or climbing hills, and has disadvantages such as high physical energy consumption and insufficient speed. And only have both feet to step on motion when riding, and both hands keep still basically, and both hands are often frozen and numb in the cold season. [0003] For the problems referred to above, the patent No. is 200720001556.8, and the name is called the Chinese patent of pedal hand-pulled bicycle, whic...
