Description
Technical Field
The utility model relates to the field of bicycle accessories, in particular to a handlebar heightening device of a mountain bicycle.
Background
The existing mountain bike is low in handlebar mounting position, and a rider needs to bend over to ride the bike. After long-time riding, the waist muscle of a rider can bear great labor intensity, so that waist soreness is caused, and the requirement that the rider can easily ride the bicycle by directly riding the waist like a common bicycle in the riding process cannot be met. For this reason, accessories for heightening handlebars of mountain bikes have appeared in the market. At present, the height increasing accessories of the mountain bike mainly have two types, one type is a hard height increasing mode, namely, the handlebar is lifted by a hard connecting piece; the other is a hinged connection mode, the two parts are divided into a first part and a second part, the first part is connected with a rotating shaft of the front wheel, the second part is connected with the handlebar, the height of the handlebar can be changed by adjusting the angle between the two parts, and therefore the bending degree of the waist of a rider can be changed.
The two existing methods for heightening the handlebar have two defects: firstly, tools are used, and the handlebar cannot be quickly lifted; secondly, the adjustable spatial position of handlebar, including vertical height and horizontal displacement volume are all less, can't reach and make mountain bike use like ordinary bicycle, and the cyclist still need to keep more obvious state of bowing.
