The invention discloses a level gage for constructional engineering. The structure thereof comprises a fixing base, a support pillar, a base, a disk, a level gage main body, a rough sighting device, an objective glass, an objective glass cap and an eyepiece, wherein a connecting shaft is fixedly connected with the upper end surface of the fixing base; the disk is movably connected with the upper end surface of the base; the level gage main body is movably connected with the upper end surface of the disk; a coincidence level magnifying lens is fixedly connected with the right part of the front end surface of the level gage main body; the objective glass is moveably connected with the right end surface of the level gage main body; the objective glass lens is movably connected with the right end surface of the objective glass; the objective glass cap is moveably connected with the right end surface of the objective glass lens. According to the invention, in the process of measuring the altitude difference between two points on the constructional engineering ground, certain harmful light is shielded for the objective glass, the objective glass lens is protected and the dustproof and water splashing preventing treatment is performed under nonuse state, the head and lens of the objective glass are prevented from being damaged by improper storage and the reliable performance of the device is effectively promoted.
Description
technical field [0001] The invention relates to a building engineering level and belongs to the technical field of level manufacturing. Background technique [0002] A level is an instrument for establishing a horizontal line of sight to measure the height difference between two points on the ground. The principle is to measure the height difference between ground points according to the leveling principle. The main components are telescope, tube level or compensator, vertical shaft, base, foot screw. According to the structure, it can be divided into micro-tilt level, automatic leveling level, laser level and digital level. According to the accuracy, it can be divided into precision level and ordinary level. Levels are suitable for leveling instruments. Chinese levels are divided into 4 grades according to the accuracy index of the occasional medium error in the round-trip height difference per kilometer that the instrument can achieve. [0003] The prior art public app...
