Description

Technical Field

[0001] The utility model belongs to the technical field of engineering cost, and in particular relates to a measuring ruler for engineering cost which is easy to adjust. Background Art

[0002] Project cost refers to the estimated or actual construction costs of a project during the construction period. In the project cost industry, it is often necessary to measure the drawings to obtain some data. In this process, a drawing measuring ruler is needed to measure the length and angle of the graphic content on the drawing.

[0003] At present, drawing measuring rulers are often prone to insufficient length during the measurement process. It is difficult for existing measuring rulers to quickly extend the basic length of the measuring ruler, which affects the drawing measurement efficiency of the measuring ruler, greatly reduces the measuring range of the measuring ruler, increases the limitations of the measuring ruler during the measurement process, and is not conducive to the use of operators. Utility Model Content

[0004] The utility model aims to provide a measuring ruler for engineering cost which is easy to adjust, so as to solve the problem that the existing measuring ruler is difficult to quickly extend the basic length of the measuring ruler, thus affecting the drawing measurement efficiency of the measuring ruler.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a measuring ruler for engineering cost that is easy to adjust, comprising: a measuring ruler, a protractor connected to one side of the bottom of the measuring ruler, an extension component arranged on one side of the measuring ruler, the extension component comprising a receiving slot, the receiving slot is opened on one side of the measuring ruler, and the receiving slot and one side wall of the measuring ruler are interconnected, an extension ruler is rotatably connected to one side of the inner wall of the receiving slot by a hinge, a through slot is opened between the two sides of the extension ruler, and a limiting block is opened between the side wall of the extension ruler and the through slot, the limiting block is located at one end inside the through slot and connected to a limiting plate, a limiting slot matching the limiting block is opened on one side of the inner wall of the receiving slot, a groove is opened on one side of the side wall of the measuring ruler and the extension ruler, a magnet is arranged inside the groove; a protective component is arranged inside the receiving slot.

[0006] Preferably, the protective component includes a slide groove, and the two slide grooves are symmetrically opened on both sides of the inner wall of the storage groove, and the two slide grooves are mutually connected with one side wall of the measuring ruler, and the interiors of the two slide grooves are slidably connected with a slider, one side of one of the sliders is provided with a threaded hole, and a protective plate is connected between the two sliders, and a bolt passes through the bottom of the measuring ruler and the slide groove, and one end of the bolt is threadedly connected to the slider through the threaded hole.

[0007] Preferably, two guide rods are connected between the two sides of the inner wall of the through groove, and the two guide rods respectively pass through the two sides of the limiting plate.

[0008] Preferably, a rubber pad is provided inside the limiting groove.

[0009] Preferably, one end of the bolt is connected to a torsion plate, and arc grooves are formed on both sides of the torsion plate.

[0010] Preferably, the protective plate is configured to be transparent.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] (1) The utility model provides an extension component. When the basic length of the measuring ruler needs to be extended, the limit plate is pulled so that the limit plate drives the limit block to move toward the inside of the through slot, so that the limit block is separated from the limit slot, thereby releasing the limit of the extension ruler in the storage slot. The side wall of the extension ruler is combined with the side wall of the measuring ruler through a hinge, and the measuring ruler and the extension ruler are connected through a magnet, thereby realizing the rapid extension of the basic length of the measuring ruler, improving the drawing measurement efficiency of the measuring ruler, reducing the limitations of the measuring ruler in the measurement process, and facilitating the use of operators.

[0013] (2) The utility model provides a protection component. When it is necessary to protect the extension ruler inside the storage slot, the sliders on both sides of the protection plate are inserted into the slide slot through the side walls of the measuring ruler. The protection plate is then moved inside the storage slot through the sliders and the slide slot to cover the extension ruler. The bolt is then screwed so that one end of the bolt is threadedly connected to the slider through the threaded hole, thereby limiting the position of the protection plate inside the storage slot. The extension ruler is protected inside the storage slot, and the extension ruler is prevented from being worn out and causing unclear scale lines. This is beneficial to the normal use of the extension ruler and improves the practicality of the extension ruler. BRIEF DESCRIPTION OF THE DRAWINGS
