Embodiment 1

[0019] Embodiment one, a kind of bicycle, such as figure 1 Shown, comprise: handle standpipe 5, front fork 8, the handle stand pipe 5 of bicycle and front fork 8 upper end bearing places are pressed adornment reverser 6.

[0020] Such as figure 1 As shown, wherein, 1. frame beam; 2. C-shaped clip; 3. bolt; 4. handle; 5. handle riser; 6. reverser; 7. frame;

[0021] In the bicycle of the present invention, a "steering reverser 6" is installed on the handle standpipe 5 of the bicycle and the upper end of the vertical shaft of the front fork 8 (the bearing at the upper end of the front fork), which is referred to as the reverser 6. When handle 4, steering moment makes front fork 8 and bicycle front wheel turn to the opposite direction by reverser 6.

Embodiment 2

[0022] Embodiment two, a kind of bicycle, such as figure 2 Shown, on the basis of embodiment one, further be:

[0023] Further, the reverser 6 includes a set of bevel gears, namely: a bevel gear 13 , a bevel gear 10 , and a bevel gear 17 .

[0024] Further, one end of the bevel gear 13 is a bevel tooth surface, and the other end is a hollow shaft. The hollow shaft is assembled with the reverser housing 14 through the bearing 12 , and the inner hole of the hollow shaft is assembled with the handle standpipe 5 .

[0025] Further, the inner hole of the hollow shaft is assembled with the handle standpipe 5 and fastened by the top screw 11 to make the bevel gear 13 rotate synchronously with the handle.

[0026] Further, for the bevel gear 10, one end of the shaft shaft 9 is fixed to the reverser housing 14 through threads, and the other end is assembled with the bevel gear 10, and the shaft shaft 9 is used as the fixed rotating shaft of the bevel gear 10; the bevel gear 10 and th...

Abstract

The invention discloses a bicycle and relates to the technical fields of ergonomics teaching experiment equipment, special industry skill testing projects and entertainment fitness equipment. The technical problem that an existing mirror image drawing test has single items is solved. According to the technical scheme, the bicycle comprises a handlebar vertical pipe and a front fork. A reverser is installed at the position of a bearing at the upper end of the front fork and the handlebar vertical pipe of the bicycle.

Description

technical field [0001] The invention relates to the technical fields of ergonomics teaching experiment equipment, special industry skill test items, entertainment and fitness equipment, and in particular to a bicycle. Background technique [0002] In the majors of industrial engineering and industrial design in universities, the course "Ergonomics" is generally offered. One of the experimental contents of the human body function test experiment "mirror drawing" in the course is called the mirror drawing instrument. The eyes observe the graphics through a mirror. During the test, the tested personnel can only look at the graphics in the mirror with their eyes and block the peripheral vision of the eyes. They use a pen to draw on the graphics within the specified time. Since the mirror image and the real object are reversed Yes, it is difficult to complete successfully under normal logical thinking. The purpose of the experiment is to examine the ability of human perception an...
