Front fork measuring instrument of tricycle

Abstract

The invention discloses a front fork measuring instrument of a tricycle. A gradienter measuring head is connected with a fixed shaft, the fixed shaft is made of distortion-free aluminum magnesium alloy, the middle at the upper end of the fixed shaft is slotted, the lower end of the gradienter measuring head is inserted into the lower end of the slot so as to connect the gradienter measuring head with the fixed shaft through a fixing pin, an upper taper sleeve is installed at the upper part of the fixed shaft, the lower end of the fixed shaft is lathed with threads matched with inner hole threads of a lower taper sleeve so as to adapt to various branch pipe lengths, the center scale mark on the outside of the upper end of the fixed shaft is matched with the scale on the gradienter measuring head, the top end of the inside of the upper end of the fixed shaft is processed with engaging teeth matched with a waist type adjustable bolt of the gradienter measuring head, the outside of the waist type adjustable bolt is provided with an adjusting rotary knob, and a water pipe bubble type gradienter is installed at the upper part of the gradienter measuring head. When the measuring instrument is used for measuring, the fixed shaft is fixed on a front branch pipe, a prediction angle is parallel to the scale surface of the gradienter measuring head, the rotary knob is regulated to enable the gradienter bubble to be in the middle, and then the scale value corresponding to an indicating line at the upper end of the fixed shaft is checked, so as to obtain a tilt angle.

Description

technical field [0001] This patent relates to the technical field of tricycle measurement, in particular to a tricycle front fork angle measuring instrument. Background technique [0002] At present, for vehicles such as tricycles, electric tricycles, and bicycles, there are no reliable inspection and measurement tools and instruments for the verticality and inclination of the front fork tubes during the production and maintenance process, which brings unnecessary troubles to the production process and relies entirely on tooling. Positioning, long-term production and processing, and small changes lead to changes in the verticality and inclination of the front fork tube. Since there is no special measuring instrument, it cannot be measured accurately, resulting in poor product consistency. Contents of the invention [0003] The purpose of this patent is to provide a tricycle front fork angle measuring instrument for current tricycles, electric tricycles, bicycles and other ...

[0002] At present, vehicles such as tricycles, electric tricycles, bicycles, etc. have no reliable inspection and measurement tools and instruments for the verticality and inclination of the front fork tube during the production and maintenance process, which brings unnecessary troubles to the production process and relies entirely on tooling. Positioning, long-term production and processing, and small changes lead to changes in the verticality and inclination of the front fork tube. Since there is no special measuring instrument, the measurement cannot be performed accurately, resulting in poor product consistency
