Description

Technical Field

[0001] This utility model relates to a marking device, and more particularly to a marking device for double sides of a square tube. Background Technology

[0002] In the process of manually cutting square tubes, it is often necessary to scribing lines on both sides of the square tube. If you do not have the necessary tools and simply scribing by hand, the scribing on both sides will have a large deviation. Previously, we also used some bending templates for scribing, but some bending templates are only applicable to square tubes of the corresponding size. For square tubes that exceed the size of some bending templates, we need to find other scribing tools to scribing, which is inconvenient to operate and has low work efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a square tube double-sided marking device that can be spliced ​​to any length and can be used for double-sided marking of various specifications of square tubes.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A double-sided marking device for square tubes includes a marking unit comprising a marking adsorption block, a left connecting block, and a right connecting block. The marking adsorption block has a magnet placement groove, within which a magnet is placed for adsorption. The magnet can be adsorbed into the magnet placement groove, and in use, the device is attached to a square tube made of steel using the magnet.

[0005] The left side of the marking adsorption block is provided with a left connecting cavity and the left connecting block, and the right side is provided with a right connecting cavity and the right connecting block. The left connecting block and the right connecting block are staggered, and the left connecting cavity and the right connecting cavity are also staggered. A connecting post is provided in the left connecting cavity, one end of which is connected to the left connecting block. A limiting hole is provided on the right connecting block, which is parallel to the connecting post and penetrates the right connecting block. The connecting post matches the limiting hole.

[0006] Furthermore, the inner diameter of the limiting hole matches the outer diameter of the connecting post, allowing the connecting post to rotate within the limiting hole.

[0007] Furthermore, the size of the left connecting block matches the size of the right connecting cavity; the size of the right connecting block matches the size of the left connecting cavity.

[0008] Furthermore, the ends of the left and right connecting blocks that are away from the scribing adsorption block are arc-shaped, which facilitates the rotation of each pair of scribing units around the connecting column when multiple scribing units are connected.

[0009] Furthermore, the marking unit is made of Q235 steel, which facilitates the placement and attraction of magnets.

[0010] Furthermore, the scribing adsorption block, the left connecting block, and the right connecting block are an integrated structure, and the left connecting block and the connecting post are an integrated structure.

[0011] Furthermore, multiple scribing units are provided, and each pair of scribing units can be connected together using their limiting holes and connecting posts. That is, the connecting post on one scribing unit can be inserted into the limiting hole on another scribing unit to form a chain scribing device.

[0012] The resulting chain scribing device can be composed of two or more scribing units connected together. Depending on the size of the square tube to be scribed on both sides, the number of scribing units can be increased or decreased to adapt to square tubes of different sizes, thus enabling double-sided scribing on square tubes of different sizes.

[0013] Furthermore, each pair of scribing units is connected together by limiting holes and connecting posts, which makes connection and disassembly convenient. If any scribing unit is damaged, it can be quickly disassembled and replaced, making it easy to use.

[0014] The beneficial effects of this utility model are as follows: 1. This utility model utilizes a scribing unit with magnets to scribing lines on both sides of a square tube. The number of scribing units can be arbitrarily increased or decreased to accommodate square tubes of different sizes, as required by the size of the square tube to be scribed on both sides. It can be imagined as a chain structure that can only be bent arbitrarily in one plane, thus enabling double-sided scribing on square tubes of different sizes. It has a wide range of applications. With the assistance of magnets, a closed loop can be formed, ensuring that the lines drawn by scribing the circumference are on the same plane with small scribing deviation.

[0015] 2. The scribing units in this utility model are connected together by limiting holes and connecting posts, which is convenient to connect and disassemble. If any scribing unit is damaged, it can be quickly disassembled and replaced. The operation is simple and convenient to use.
