Abstract

The invention discloses a multi-purpose measuring ruler for engineering measurement, which comprises a tape measure box, the outer surface of the bottom of the tape measure box is integrally fixedly connected with a dial, and the edge surface of the tape measure box is fixedly connected with one end of the scale plate. The straight side is fixed, and the center of the bottom of the tape measure box is rotatably embedded with a rotating shaft. The present invention can realize angle measurement on the basis of traditional length measurement through the increased dial, number of scales, fixed straight sides and movable straight sides, and realize the multi-purpose function of tape measure, wherein the fixed straight side and movable straight side can be positioned to be Measure the two corners of the object. The specific value of the angle formed by the two corners can be determined through the dial and the number of scales. Through the design of the rotating shaft, pressing button and reserved ring groove, it is convenient to rotate the movable straight side to the point to be measured. The corners and edges of the object are fitted, and through the design of the splined round block, the splined round groove and the extension spring, it is convenient to limit the movable straight side after the rotation adjustment.

Description

technical field [0001] The invention relates to the technical field of engineering measurement, in particular to a multi-purpose measuring ruler for engineering measurement. Background technique [0002] The measuring ruler for engineering measurement is a device for measuring various lengths and angles in engineering construction. The length measuring tool has a measuring tape. The measuring tape coils a cloth ruler or a tape measure inside the tape measure box. When measuring, take out the tape measure and the measurement is over. The rear tape measure is automatically stored in the tape measure box. [0003] Traditional engineering measuring rulers, such as measuring tapes, can measure lengths, but cannot measure angles. Contents of the invention [0004] (1) Purpose of the invention [0005] In order to solve the technical problems in the background technology, the present invention proposes a multi-purpose measuring ruler for engineering measurement. [0006] (2) T...
