Problems solved by technology

In the existing QB1802-1993 Appendix A3, it is stipulated that the measuring device of the bicycle rim tape measure is carried out by using a physical touch core that simulates the diameter of the bicycle rim. It is often composed of dozens of standard physical touch cores, and such solid touch cores are generally made of metal materials, and the diameter is generally between Φ300mm ~ Φ700mm, so there are huge measuring devices, high processing difficulty, and low measurement efficiency. Disadvantages, can not solve the technical problem of measuring the length of all bicycle rim tapes with a set of standard instruments

Abstract

The invention discloses a measuring device of a bicycle wheel rim measuring tape. The device is composed of a circumference-surface-shaped workbench 1, a reading microscope 2, an adjustable fixing sleeve 3, a support column 4, a locking mechanism 5, a standard measuring tape tail clamping apparatus 6, a standard measuring tape head clamping apparatus 7, a pulley 8, a support 9, a standard measuring tape 10, a wheel rim measuring tape 11, a wheel rim measuring tape head clamping apparatus 12, a line rope 13, a weight 14, a base 15, adjusting foot margins 16 and a fine tuning mechanism 17. The measuring device solves the technical problem that the lengths of all kinds of bicycle wheel rim tapes are measured by using one set of standard devices under a state nearest to the use state of the bicycle wheel rim measuring tape, and improves measurement precision and measurement efficiency.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a measuring device for a bicycle rim tape ruler. Background technique [0002] The bicycle rim tape ruler is a special measuring instrument for detecting the circumference of the bicycle rim. It uses one end face of the tape ruler for positioning, coincides with a certain scale on the scale line on the other end of the tape ruler, and is combined into a closed ring. Determine whether the circumference of a bicycle rim of a certain specification is within the qualified range. In the existing QB1802-1993 Appendix A3, it is stipulated that the measuring device of the bicycle rim tape measure is carried out by using a physical touch core that simulates the diameter of the bicycle rim. It is often composed of dozens of standard physical touch cores, and such solid touch cores are generally made of metal materials, and the diameter is generally between Φ300mm ~ Φ700mm, so there are huge mea...
