An electric bicycle handlebar thermochromic layer spraying device

Abstract

The invention discloses a spraying device for a temperature-sensitive color changing layer of an electric bicycle. The device comprises a bottom plate; a sprayer is arranged on the bottom plate; a guide pipe which is internally sleeved with a lifting pipe is arranged on the bottom plate; the guide pipe is equipped with a rotating pipe; the lifting pipe is in threaded connection with the guide pipe; a rotating ball is arranged at the end part of the lifting pipe, and a connecting ball sleeve the peripheral surface of the rotating ball; a plurality of sleeve pipes are arranged on the peripheral surface of the connecting ball; a spraying ball is arranged at the end part of the guide pipe; the connecting ball and the sleeve pipes are arranged in the spraying ball; a spraying channel is arranged on the inner wall of the spraying ball; a spraying hole is formed in the inner wall of the spraying ball. According to the device, the handle can be mounted on the sleeve pipes, the temperature-sensitive color changing liquid can be stored in the sprayer and conveyed into the spraying channel through a conveying pipe, and then the temperature-sensitive color changing liquid is sprayed out through the spraying hole and injected onto the surface of the handle on the sleeve pipes, so that the function of spraying the temperature-sensitive color changing liquid can be achieved, and the temperature-sensitive color changing type handle can be prepared; the rotating pipe can control the lifting pipe to rotate, so that the spraying uniformity is improved.

Description

technical field [0001] The invention relates to a spraying device, in particular to a spraying device for a thermochromic layer of a handlebar of an electric bicycle. Background technique [0002] Handlebar, one of the essential parts of a bicycle, is used when riding, pushing, or pulling a bicycle with a handle held by hand. You can't ride a bike without handlebars. It is a handle that is held by hand when riding a bicycle, pushing a cart, or pulling a cart. It is a control device for controlling the direction of a motorcycle, which is equivalent to the steering wheel of a car. The handlebars should be firmly installed in the bodywork and keep the handlebars balanced. Use the principle of leverage to turn the wheel and change the direction. The lever that controls the steering of the front wheel: the handlebar of the bicycle is a labor-saving lever, and people can turn the front wheel of the bicycle with a small force to control the direction of movement of the bicycle ...

AI Technical Summary

Problems solved by technology

The existing handlebars do not have the function of temperature-sensitive discoloration, and there is no special spraying equipment for handlebars, so it is inconvenient to spray handlebars
