Description

Technical Field

[0001] This invention relates to the field of steel structure engineering, and in particular to a quick-set ruler for transverse and longitudinal baselines for plates of any thickness. Background Technology

[0002] The component consists of a panel and parts. Before assembling the parts, horizontal and vertical reference lines need to be drawn on the upper surface of the steel plate while it is laid flat. When the structure of the plate is designed such that there are parts on the other side of the panel, or when there are measurement reference points on the other side of the panel, lines need to be drawn on both sides of the panel. In this case, it is necessary to trace the lines from one side to the other.

[0003] Current methods and tools for retracing lines typically involve using a right-angle ruler to first trace the horizontal baseline to the thickness direction of the sheet metal, and then trace it back to the other side from the thickness direction. This not only results in low work efficiency but also makes it prone to accuracy deviations. Therefore, a tool that can directly trace lines is needed to improve work accuracy and efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a quick re-line ruler for horizontal and vertical reference lines of plates of any thickness, which can solve the problem that the general plate re-line uses a right-angle ruler, which has low work efficiency and is prone to accuracy deviation.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a quick reversal ruler for horizontal and vertical reference lines of plates of arbitrary thickness, the innovation of which is: including a base plate, a top plate, a guide plate, an upper alignment ruler plate, a lower scribing ruler plate, a ruler strong magnet and a pull rod;

[0006] The base plate is horizontally set on the ground, and the guide plate includes a pair of parallel plate units, which are vertically set on the upper surface of the base plate; the top plate is vertically set on the top of the guide plate, and the top plate has a through hole for accommodating the pull rod, and the through hole is located between the two plate units.

[0007] The upper alignment ruler plate is vertically connected to the guide plate. The upper alignment ruler plate includes a guide slider and a ruler plate unit. The guide slider is connected to one end of the ruler plate unit. The guide slider has a pair of slots along the vertical direction that mate with the plate unit. The slots of the guide slider are nested in the plate unit and can move vertically along the plate unit. The ruler plate unit has a ruler groove along the extension direction. The other end of the ruler plate unit is provided with a ruler magnet, and the bottom end of the ruler magnet is flush with the lower surface of the ruler plate. The ruler magnet is provided with a switch. Turning on the switch allows the ruler magnet to be attracted to the plate, and turning off the switch removes the magnetism.

[0008] The underline ruler plate is vertically connected to the guide plate. A gap is formed between the underline ruler plate and the upper line ruler plate to accommodate the plate. One end of the underline ruler plate has a guide groove that is nested in the plate unit. The underline ruler plate has a scribing groove along the extension direction. The lower surface of the underline ruler plate with the guide groove rests on the upper surface of the base plate.

[0009] The pull rod is vertically mounted on the top plate, with its bottom end extending through a through hole in the top plate to the space between the two vertical plate units. The top end of the pull rod extends above the top plate and has a handle. The bottom end of the pull rod is connected to a guide slider at the end of the upper alignment ruler plate. The pull rod drives the upper alignment ruler plate to move vertically, thereby adjusting the distance between the upper alignment ruler plate and the lower alignment ruler plate.

[0010] Furthermore, the thickness of the guide slider on the upper alignment scale plate is greater than the thickness of the scale plate unit on the upper alignment scale plate.

[0011] The advantages of this invention are:

[0012] 1) In this invention, the spacing between the upper alignment ruler plate and the lower scribing ruler plate is adjusted to handle plates of different thicknesses. The ruler groove on the upper alignment ruler plate is aligned with the horizontal and vertical baselines of the plate. The ruler magnet is then activated to adhere to the upper surface of the plate. After the lower scribing ruler plate is in close contact with the plate, a sliding needle is used to scribing and re-line the plate in the scribing groove on the lower scribing ruler plate. Finally, the ruler magnet is released to complete the scribing. This device can be used to re-line the horizontal and vertical baselines of plates of any thickness. It has high re-line accuracy, simple steps, convenient operation, simple structure, and few components. Attached Figure Description
