Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary tools for pipe processing, specifically to an auxiliary ruler for cutting saddle-shaped notches in pipes. Background Technology
[0002] In the field of pipe fabrication and installation, it is often necessary to cut saddle-shaped notches on pipes to achieve connections between pipes or the installation of branch pipes. However, traditional methods of cutting saddle-shaped notches mainly rely on workers' manual experience to draw lines, which has several problems. On the one hand, due to the limited precision of manual drawing, errors are prone to occur, resulting in saddle-shaped notches that do not match the actual required shape and size, affecting the quality of subsequent pipe connections and installation results. On the other hand, manual drawing is inefficient, especially for larger pipes, where manual operation is more difficult and it is hard to ensure the consistency of each cut notch, causing great inconvenience to pipe construction and potentially leading to reduced construction quality and wasted resources.
[0003] Therefore, it is necessary to develop an auxiliary tool for cutting saddle-shaped notches in pipelines that can solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to overcome the above-mentioned problems and provide an auxiliary ruler for cutting saddle-shaped notches in pipes. To achieve the above objective, this utility model adopts the following technical solution:
[0005] A pipe saddle-shaped notch cutting auxiliary ruler includes an auxiliary ruler body, a drawing template on the top of the auxiliary ruler body, the drawing template being wavy, the length of the auxiliary ruler body being equal to the circumference of the pipe opening, and a fixing component on the auxiliary ruler body. The left and right ends of the auxiliary ruler body are fixed together by the fixing component, and the drawing template after being closed together forms a saddle opening.
[0006] As an improvement, the line drawing template includes two peaks and two troughs.
[0007] As an improvement, the fixing component includes a fixing strap and several loops. The loops are disposed on the auxiliary ruler body. One end of the fixing strap is provided with a buckle. The fixing strap passes through the loops and is fixed to the auxiliary ruler body. The left and right ends of the auxiliary ruler body are fixed together by buckles.
[0008] As an improvement, the number of loops is not less than three.
[0009] The advantages of this utility model are:
[0010] 1. Compared with the traditional manual drawing method, this utility model provides a precise outline for drawing saddle-shaped notches through a unique drawing template design, avoiding errors caused by manual experience in drawing lines, significantly improving the precision and accuracy of cutting, and ensuring the connection quality of pipes.
[0011] 2. With the auxiliary ruler of this utility model, workers do not need to spend a lot of time and effort to estimate and draw the saddle-shaped gap line. They only need to fix the auxiliary ruler on the pipe and draw the line along the template, which greatly shortens the drawing time and improves the overall work efficiency of pipe processing.
[0012] 3. The length of the auxiliary ruler body of this utility model can be selected according to the circumference of the pipe opening. Different specifications of auxiliary ruler bodies are suitable for pipes of corresponding diameters, and have wide applicability, which can meet the needs of various pipe processing scenarios.

[0024] The present invention will be described in detail below through specific embodiments to enable a better understanding of the present invention. However, the following embodiments do not limit the scope of protection of the present invention.
[0025] Example 1
[0026] This embodiment discloses an auxiliary ruler for cutting saddle-shaped notches in pipelines.
[0027] like Figures 1 to 3 As shown, this embodiment includes an auxiliary ruler body 1, a drawing template 2 on the top of the auxiliary ruler body 1, the drawing template 2 is wavy, the length of the auxiliary ruler body 1 is equal to the circumference of the tube opening, a fixing component is provided on the auxiliary ruler body 1, the left and right ends of the auxiliary ruler body 1 are fixed together by the fixing component, and the drawing template 2 after being enclosed forms a saddle opening 3.
[0028] The auxiliary ruler body 1 has a length equal to the circumference of the pipe opening, ensuring it can completely encircle the pipe. As the base supporting other components, the auxiliary ruler body 1 provides support for the marking template 2 and fixing components. Its length can be customized according to different pipe diameters to meet the processing requirements of various pipe specifications. This utility model is applicable to pipe diameters including...
[0029] Various pipe diameters such as DN100, DN150, DN200, DN250, and DN300 are available. This example uses a pipe diameter of DN300.
[0030] The drawing template 2, with its wavy shape design, accurately simulates the outline of a saddle-shaped notch. Once the auxiliary ruler body 1 is fixed around the pipe, the drawing template 2 can be directly used as a reference line for cutting, avoiding the inaccuracies of manually drawing saddle-shaped notch lines based on experience.
[0031] The line drawing template 2 includes two peaks 4 and two troughs 5.
[0032] The fixing component includes a fixing strap 6 and several loops 7. The loops 7 are set on the auxiliary ruler body 1. One end of the fixing strap 6 is provided with a buckle 8. The fixing strap 6 passes through the loops 7 and is fixed to the auxiliary ruler body 1. The left and right ends of the auxiliary ruler body 1 are closed and fixed by the buckles 8.
[0033] This embodiment features four loops 7, with two loops 7 positioned at the left and right ends of the auxiliary ruler body 1, respectively. In use, the fixing strap 6 passes through the loops 7, enclosing and fixing the left and right ends of the auxiliary ruler body 1 to the pipe. Through the fixing components, the auxiliary ruler can firmly adhere to the pipe surface, ensuring no displacement during drawing and cutting, thus guaranteeing the accuracy of the lines.
[0034] How to use this embodiment:
[0035] The auxiliary ruler body 1 is wrapped around the pipe where the saddle-shaped notch needs to be cut. The fixing strap 6 of the fixing component passes through the loop strap 7, and the left and right ends of the auxiliary ruler body 1 are closed and fixed using the buckle 8. The length of the fixing strap 6 and the distribution of the loop strap 7 are carefully designed to ensure that the fixed auxiliary ruler body 1 can fit tightly against the pipe surface without loosening or shifting.
[0036] After the auxiliary ruler body 1 is fixed, since its length is equal to the pipe circumference and the top drawing template 2 is wavy, containing two peaks 4 and two troughs 5, it perfectly simulates the shape of a saddle-shaped notch. Workers can directly use the drawing tool to draw a precise saddle-shaped notch line on the pipe along the outline of the drawing template 2, without having to rely on manual experience for estimation and drawing, greatly improving the accuracy of the drawing.
[0037] After the lines are drawn, workers can use cutting tools to cut saddle-shaped notches into the pipes according to the lines. Because the lines are drawn precisely using an auxiliary ruler, the shape and size of the cut saddle-shaped notches will be more accurate, ensuring the quality of pipe processing.

[0041] The line drawing template 2 includes two peaks 4 and two troughs 5.
[0042] The fixing component includes a fixing strap 6 and several loops 7. The loops 7 are set on the auxiliary ruler body 1. One end of the fixing strap 6 is provided with a buckle 8. The fixing strap 6 passes through the loops 7 and is fixed to the auxiliary ruler body 1. The left and right ends of the auxiliary ruler body 1 are closed and fixed by the buckles 8.
[0043] The number of loops 7 is not less than three. This embodiment is for a pipe diameter of DN150, and this embodiment has three loops 7.
