Description

Technical Field

[0001] This utility model relates to the field of pipe measurement technology, specifically a convenient pipe acceptance measuring tool. Background Technology

[0002] A π ruler, also known as a diameter ruler, diameter measuring tape, or π tape measure, is a flexible measuring tape specifically designed for measuring pipes. It is not commonly seen in daily life and is mainly used in the pipe manufacturing and processing industry for the acceptance measurement of pipe diameters.

[0003] When using it, simply wrap the measuring tape around the pipe and read the value according to the scale markings to obtain the pipe's diameter. If you use a ruler to measure the diameter, it is difficult to accurately find the diameter passing through the center of the circle. The measuring tape's scale markings are designed based on the relationship between circumference, pi, and diameter, making diameter measurement both accurate and convenient.

[0004] Most existing measuring rods are simply thin stainless steel sheets with a simple structure. To ensure sufficient flexibility, they are manufactured with a relatively small thickness. At the same time, the surfaces of the measuring rod and the tube are relatively smooth. When using the measuring rod, not only is it inconvenient to hold due to its small thickness, but the measuring rod also slides between itself and the surface of the tube during the reading process, affecting stability and thus affecting the ease of reading and use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a convenient pipe acceptance measuring tool that is easy to hold and has a non-slip surface against the pipe, thereby facilitating reading and improving ease of use.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A convenient pipe acceptance measuring tape includes a flexible measuring tape. The flexible measuring tape includes a zero-scale end portion, a bent portion, and a measuring portion, which are integrally structured. The zero-scale end portion and the measuring portion are located on both sides of the bent portion and are parallel to each other. The zero-scale end portion and the measuring portion are staggered vertically. Measurement scale marks are equidistantly provided on the front of the zero-scale end portion near the bent portion and on the front of the bent portion and the measuring portion. Anti-slip pads are equidistantly provided on the back of the zero-scale end, the bent part, and the measuring part. Thickened handles are installed on the opposite surfaces of the zero-scale end and the measuring part. Anti-slip blocks are fixedly embedded on the front and back of the thickened handles.

[0007] Preferably, the flexible ruler strip is a flexible stainless steel strip, and the edges are polished and rounded.

[0008] Preferably, the measuring portion is located to the upper right of the zero-scale end portion, and the lower edge of the measuring portion and the upper edge of the zero-scale end portion are on the same horizontal line.

[0009] Preferably, the back of the zero-scale end portion, the bent portion, and the measuring portion are provided with grooves at equal intervals, and the anti-slip pad is fixedly embedded in the grooves.

[0010] Preferably, the depth of the groove does not exceed half the thickness of the flexible tape, the anti-slip pad is an elastic soft pad, and the thickness of the anti-slip pad protruding from the groove is 0.1-0.5 mm.

[0011] Preferably, each of the two thickened handles includes two handle housings clamped to the front and back of the flexible tape end, and each of the two housings of the thickened handle is provided with a groove, and the anti-slip rubber block is fixedly embedded in the groove.

[0012] Preferably, the groove is provided with a countersunk hole and a screw is installed thereon, the screw passing through the flexible measuring tape and connected to the thickened handle.

[0013] Preferably, the anti-slip rubber block is an elastic anti-slip pad block, and the surface of the anti-slip rubber block is also provided with anti-slip protrusions.

[0014] Preferably, the ends of the thickened handle are rounded, and the overall thickness of the thickened handle is not less than 10 mm.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention features significantly thickened handles at both ends of a flexible measuring tape, with anti-slip rubber blocks on the handles to prevent slippage and facilitate handling and operation. Additionally, an elastic anti-slip pad is provided on the back of the flexible measuring tape to increase friction between the tape and the pipe.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a convenient pipe acceptance measuring tape, including a flexible measuring tape 1, which is a flexible and bendable stainless steel strip with a fixed length, making the measurement stable and reliable. The edge part is polished and ground into a rounded corner structure without a blade, improving the user experience. The flexible measuring tape 1 includes a zero-scale end portion 101, a bending portion 102, and a measuring portion 103, which are integrally structured. The zero-scale end portion 101 and the measuring portion 103 are located on both sides of the bending portion 102 and are parallel to each other. The zero-scale end portion 101 and the measuring portion 103 are vertically offset. The measuring portion 103 is located to the upper right of the zero-scale end portion 101, and the lower edge of the measuring portion 103 is on the same horizontal line as the upper edge of the zero-scale end portion 101.

[0020] Measurement scale marks 104 are equidistantly provided on the front of the zero-scale end portion 101 near the bending portion 102, as well as on the front of the bending portion 102 and the measuring portion 103. When in use, the flexible tape 1 is wrapped around the pipe, the lower edge of the measuring portion 103 merges with the upper edge of the zero-scale end portion 101, and the reading can be taken by pulling the thickened handle 3 to tighten the flexible tape 1. The specific reading method is the same as that of the existing tape measure.

[0021] Anti-slip pads 2 are equidistantly arranged on the back of the zero-scale end portion 101, the bent portion 102, and the measuring portion 103. Grooves 105 are equidistantly arranged on the back of the zero-scale end portion 101, the bent portion 102, and the measuring portion 103.

The anti-slip pads 2 are elastic soft pads, which can be made of rubber or silicone. The thickness of the anti-slip pads 2 protruding from the grooves 105 is 0.1-0.5 mm to improve the anti-slip effect. When under pressure during use, they retract into the grooves 105 to avoid protruding and affecting measurement accuracy.
