Foldable slope measuring device for land engineering

Abstract

The invention provides a foldable slope measuring device for land engineering, and relates to the field of land engineering surveying and mapping technology. The foldable slope measuring device for land engineering comprises a shell, the front surface of the shell is rotationally connected with a rotating plate through a hinge, the front surface of the rotating plate is fixedly connected with an extrusion block, a storage groove is formed in the shell, the rear inner wall of the storage groove is fixedly connected with an extrusion spring, the end, away from the rear inner wall of the containing groove, of the extrusion spring is fixedly connected with an indicating ring, and scale marks are arranged on the front surface of the indicating ring. A rotating groove is formed in the position, located behind the storage groove, in the shell. During folding, the rotating plate is controlled to rotate, the indicating ring is extruded through the extrusion block on the rotating plate, and the indicating ring is pressed into the storage groove, so that the scale marks on the indication ring are effectively prevented from being abraded when not used, and the scale marks are well protected.

Description

technical field [0001] The invention relates to the technical field of land engineering surveying and mapping, in particular to a foldable slope measuring device for land engineering. Background technique [0002] Inclinometer is a surveying and mapping accessory product with slope measurement function. Use the slope meter to measure the downtilt angle. Use the surface a to touch the rear plane of the antenna and rotate the scale wheel. Center the water bubble in the level tube. Check the degree indicated by the indicator needle in the dial is the degree of the downtilt angle. In order to solve the problem of a certain amount of work and time, a foldable inclinometer is used for portability. [0003] When the applicant applied for the present invention, after searching, it was found that the Chinese patent disclosed "a foldable slope measuring device for land engineering", and its application number is "CN202120091646.0". The limit block and the rotating block can convenie...
