AI Technical Summary

Technical Problem

Existing multi-functional rulers are inconvenient to carry when taking measurements outdoors, have a loose structure, and the protractor part is easily caught on clothing or damaged by compression. In addition, the measurement error is large, making it difficult to meet the requirements of portability and ease of operation.

Method used

A multifunctional ruler including a protractor and an auxiliary component was designed. The protractor consists of a movable strip and a protractor, while the auxiliary component consists of an auxiliary strip and a limiting post. The protractor is stably connected by a limiting bead and a limiting groove. The extension and retraction of the auxiliary strip and the limiting post extend the measuring range of the protractor, ensuring that the protractor does not protrude when stored with the ruler at the same width.

Benefits of technology

The portability and practicality of the multi-functional ruler have been improved, the protractor protrusion and measurement errors have been avoided, the stability and accuracy of the measurement have been ensured, and the convenience of carrying it has been enhanced.

Abstract

The utility model provides a multifunctional ruler for clothing pattern making, which comprises a straight ruler, and further comprises an angle measuring assembly which comprises a movable strip and an angle measuring disc which are arranged on the straight ruler, a limiting bead arranged on the side wall of the movable strip and a plurality of limiting grooves which are formed in the straight ruler and correspond to the limiting bead, and the angle measuring assembly is used for measuring angles of the angle measuring disc at different positions; the auxiliary assembly comprises an auxiliary strip and a limiting column which are arranged on the movable strip and is used for further prolonging the measurement range of the angle measuring disc; through the arrangement of the angle measuring assembly and the auxiliary assembly, the problems that an existing folding type multifunctional ruler is long in length, and a protractor part and a straight ruler part protrude and are inconvenient to carry are solved, the angle measuring disc is rigidly connected with the movable strip, displacement deviation of a traditional detachable assembly is avoided, and it is ensured that the measuring precision is still kept after long-term use; the multifunctional ruler can be independently stored when not used, the problem that a curve section and a protractor of a traditional ruler protrude and are inconvenient to carry is solved, and the portability and practicability of the multifunctional ruler are greatly improved.
