Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] see Figure 1-5 , an ink line meter for construction measurement, comprising a body 1, the top of the front of the body 1 and the middle part of the left side are equipped with a light control output window 2, and the angle formed between the extension lines of the two light control output windows 2 is 90 The middle part of the front of the body 1 is fixed with an annular frame 9, and the outer surface of the body 1 is clamped with a control panel 3. Th...

Abstract

The invention relates to the field of construction measurement technologies and discloses a chalk line instrument for construction measurement. The chalk line instrument comprises a body, wherein light control output windows are installed in the middle of the top and the middle of the left side of the front surface of the body respectively, an included angle formed between extension lines of the two light control output windows is 90 degrees, an annular frame is fixedly installed in the middle of the front surface of the body, and a control disk is clamped to the outer surface of the body. According to the chalk line instrument for construction measurement, through an included angle formed between a fastening block in a marking device and a horizontal direction scale value inside the annular frame and an included angle formed between a vertical marking pointer in the marking device and a vertical direction scale value inside the annular frame and according to the Pythagorean theorem, it is convenient for a user to quickly calculate a height difference, namely the product of the spacing X between two control cone rods and a corresponding included angle cosine value, between offset of the chalk line instrument and corresponding offset and quickly and accurately adjust the chalk line instrument to make light, emitted by the chalk line instrument and corresponding to the light control output windows, at a horizontal position, and the speed and precision of adjusting the chalk line instrument for construction measurement to be at the horizontal position by the user are improved.

Description

technical field [0001] The invention relates to the technical field of construction measurement, in particular to an ink line meter for construction measurement. Background technique [0002] The ink line meter refers to a visible laser that can emit vertical or horizontal, and is used to mark horizontal or vertical lines on the target surface. It is a non-contact marking device used to measure whether a surface or multiple surfaces are horizontal. This instrument is mainly used in construction such as quality inspection, engineering supervision, indoor and outdoor decoration, doors and windows, hanging vertical lines and pipeline laying. [0003] During the use of the ink line meter, it needs to be installed at different heights and levels of the board according to the construction requirements. However, the existing ink line meter generally adopts the formation of a tripod for height adjustment, and is placed in the middle of the ink line meter through a round blister. po...
