Description

Technical field:

[0001] The utility model relates to the technical field of tower rulers, in particular to an engineering measurement tower ruler device. Background technology:

[0002] As a kind of level ruler, the tower ruler is often used in conjunction with a level and a theodolite. It is a very widely used measuring tool in the field of construction measurement and surveying. Most of the existing tower rulers are made of lightweight and high-strength materials such as aluminum alloy. They adopt a tower-type retractable form. The tower ruler is pulled out when in use and retracted when carried. After long-term use, the tower-type retractable structure of this tower ruler is easy to loosen, resulting in a short service life. At the same time, the length of the tower ruler is still relatively long after it is fully retracted, which is inconvenient to store and access. Utility model content:

[0003] The utility model aims to provide an engineering measurement tower ruler device to solve the technical problems of easy loosening and short service life of the tower ruler in the prior art.

[0004] The content of the utility model: An engineering measurement tower ruler device, which includes a multifunctional base and a folding tower ruler assembly, wherein the multifunctional base is used to fix the folding tower ruler assembly in an unfolded state and to store the folding tower ruler assembly in a folded state, wherein the folding tower ruler assembly includes a plurality of tower ruler units, and any adjacent tower ruler units are hinged.

[0005] Furthermore, a steel plate is installed at one end of the tower ruler unit, and a magnet sheet is installed at the other end of the tower ruler unit, and the magnet sheet magnetically attracts the steel plate of the adjacent tower ruler unit.

[0006] Furthermore, the multifunctional base includes a base and a mounting block, and the mounting block is mounted on the base.

[0007] Furthermore, a storage groove is provided on the base, and the storage groove is used to store the folding tower ruler assembly in a folded state. A plug-in groove is opened on the mounting block, and the plug-in groove is used to fix the tower ruler unit located at the bottom.

[0008] Furthermore, a handle groove is provided on the mounting block.

[0009] Furthermore, first latch holes are correspondingly opened on the mounting block and the steel plate, and a first latch is inserted into the first latch hole.

[0010] Furthermore, second latch holes are correspondingly opened on the base and the tower ruler unit, and a second latch is inserted into the second latch hole.

[0011] Beneficial effects of the utility model: the utility model designs a foldable tower ruler structure and a multifunctional base, so that the tower ruler is shorter after being folded, which is convenient for transportation, storage and unified management. The tower ruler with a foldable structure has less wear and tear and a longer service life than a traditional pull-out tower ruler. Description of the drawings:

[0012] Figure 1 It is a three-dimensional diagram of the utility model;

[0013] Figure 2 A three-dimensional diagram of the utility model in a folded state;

[0014] Figure 3 It is a cross-sectional view of the utility model in the unfolded use state;
