However, in the previous straight tube teaching process, after the teacher explained the requirements, the students were not clear about the scope of the requirements during the learning process, and there were generally errors in the production requirements. At the same time, when teachers score students' works, the scoring process takes too long, which will delay the progress of the class. During the competition, after the contestants complete part of the work, the referees need to use a large number of people to measure in batches when scoring, and they also need to score in a limited time. At the same time, they also need to score other parts, and there are many scoring items in a competition, so the referees need to score quickly when scoring to improve the efficiency of scoring. Therefore, there is an urgent need for a straight tube measurement tool to achieve rapid measurement of straight tubes. Utility Model Content

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] The utility model provides a straight tube measuring tool, comprising: a plurality of sections of measuring bodies 1 spliced ​​together, the lengths of each section of the measuring bodies 1 can be the same or different, so that the length of the spliced ​​measuring tool can be adjusted; wherein, the measuring body 1 can be made of aluminum material, and there are many varieties of aluminum materials. When selecting a measuring tool for making a straight tube, many aluminum materials are suitable for making the straight tube measuring tool. In the actual production process, several low-cost, durable, and small-size-error aluminum materials are selected for production. Aluminum products can ensure that the measured size will not deviate during long-term use. At the same time, the market price of aluminum materials is relatively cost-effective, which can reduce costs.

[0034] The measuring body 1 made of aluminum is in the shape of a rectangular parallelepiped as a whole, and its cross-section can be square or rectangular; and at least one groove 2 is hollowed out on multiple sides of the measuring body 1, that is, each side of the measuring body 1 is hollowed out with at least one groove 2, and the size of each groove 2 is different. It can be imagined that the size of the groove 2 can be set according to the diameter of the straight pipe to be measured, and the number and size of the grooves 2 can be set according to the diameter of the commonly used straight pipes in daily teaching, training or competitions, so as to meet the needs of daily use.

[0035] When measuring, it is possible to accurately understand whether the pipeline is straight. Measurements can be made in different environments and the measurement effect is the same, with high accuracy. During the measurement process, the straight pipe to be measured is directly placed in the groove 2 of the corresponding size, and the measurement result can be directly obtained by observing the matching relationship between the groove 2 and the straight pipe. Specifically, if the straight pipe produced can be placed in the groove 2 of the corresponding specification size and there is no gap, it means that the straight pipe is completely straight, exceeding the standard requirements. If the straight pipe produced can be placed in the groove 2 of the corresponding specification size and there is a gap, and the matching tool can be inserted into the gap, it means that the straight pipe meets the standard requirements. If the straight pipe produced cannot be placed in the groove 2 of the corresponding specification size or presents an ups and downs state, that is, the gap between the straight pipe and the groove 2 exceeds the deviation, it means that the straight pipe does not meet the requirements. The matching tools are existing tools, and because they are not the focus of protection of this embodiment, they are not limited here.

[0036] This straight tube measuring tool is developed, designed and manufactured in strict accordance with national standards and the standard specifications of the WorldSkills Competition. It also refers to the equipment and various requirements of the 42nd, 43rd, 44th and 45th WorldSkills Competitions. It is mainly used in daily teaching, training, competitions, etc. Since the competition assessment and scoring process requires a faster and more accurate judgment of whether the straight tube meets the requirements, this tool can measure straight tubes of various specifications at the same time to ensure that the straight tubes that meet the process requirements can be easily placed in the groove 2, and the straight tubes that do not meet the process requirements cannot be placed in the corresponding groove 2 or the straight tubes placed in the grooves will show an ups and downs state.

[0037] In the above scheme, since the straight tube measuring tool is composed of multiple sections of measuring bodies 1, the total length of the measuring tool can be freely adjusted as needed to meet the measurement needs of straight tubes of different lengths. At the same time, it is more portable to use multiple sections of measuring bodies 1. The straight tube measuring tool can be used to measure straight tubes of various specifications, meet the measurement needs of various occasions such as teaching, training, and competition, and has a wide range of applicability. In the later application in the teaching process, the teaching teacher can quickly get started and conveniently measure the straight tubes made by the students. At the same time, the students can also quickly understand where the problems are with the straight tubes they made during use, which is convenient for rapid adjustment and problem solving, reducing unnecessary review processes and improving learning efficiency. When the referee of the competition measures the straight tube, the straight tube can be quickly measured while the overly long straight tube can be measured, and the accuracy of the measurement can be guaranteed. At the same time, it can be measured whether the straight tube meets the requirements. By observing the matching relationship between the straight tube and the groove 2, the measurement result can be directly obtained without complicated calculation or operation process, making the measurement result more intuitive and easy to understand, and shortening the measurement time.

[0038] In some replaceable embodiments, the interconnected ends of two adjacent measuring bodies 1 are respectively provided with a plurality of recessed holes 3; it can be imagined that the setting positions and the number of the recessed holes 3 can be set and adjusted as needed to make the connection between the two adjacent measuring bodies 1 more stable; the recessed holes 3 on the ends of the two adjacent measuring bodies 1 are respectively set one by one to facilitate the subsequent splicing of the two adjacent measuring bodies 1, so that the splicing alignment is more precise and not easy to be misplaced.

[0039] The adjacent measuring bodies 1 are connected by magnet adsorption. Specifically, a magnet is placed in each recessed hole 3 at the end of two adjacent measuring bodies 1, so that the magnets can be adsorbed one by one, thereby achieving the connection and fixation between the adjacent measuring bodies 1; when carrying, the measuring tool can be disassembled into multiple sections for carrying, and the assembly process only requires fitting the two sides of the measuring tool together before use.

[0040] In the above scheme, adjacent measuring bodies 1 are connected by magnets, so that adjacent measuring bodies 1 can be stably connected and are not easily loosened or separated due to external factors, so that the measuring tool maintains a stable shape and position, improving the accuracy and reliability of the measurement; this connection method is simple and more convenient to install or disassemble.

[0041] In some replaceable embodiments, a plurality of clamping columns are provided at the end of one of two adjacent measuring bodies 1 having a recessed hole 3; it can be imagined that the setting position and number of the clamping columns can be set and adjusted as needed to make the connection between the two adjacent measuring bodies 1 more stable, more versatile and more compatible; the clamping columns are provided on the end of the measuring body 1 to facilitate the subsequent splicing of the two adjacent measuring bodies 1, and the connection is more convenient and efficient in combination with magnets.

[0042] Correspondingly, the other end of the two adjacent measuring bodies 1 having the recessed hole 3 is provided with a plurality of card slots 4, and the plurality of card slots 4 are arranged in one-to-one correspondence with the plurality of card columns, and the matching connection with the card columns is achieved through the card slots 4; in the specific connection process, it is only necessary to insert the card column into the corresponding card slot 4 to complete the assembly; and when disassembling, it is only necessary to pull the card column out of the card slot 4, without the need for complicated operations or tools, thereby improving work efficiency; at the same time, the card column and the card slot 4 are arranged in one-to-one correspondence, which also ensures that the measuring body 1 can maintain a precise relative position after connection, avoids errors in subsequent measurements, and improves the accuracy and reliability of the measurement.

[0043] In some feasible embodiments, each side of the measuring body 1 is hollowed out to have at least one groove 2, wherein the groove 2 should meet the specifications of the pipe diameter required for daily testing, such as: 1 / 2 pipe diameter, 1 / 4 pipe diameter, 3 / 4 pipe diameter, 3 / 8 pipe diameter and 5 / 8 pipe diameter, etc., with stronger versatility, and the side length of the groove 2 used to measure the corresponding pipe diameter size should be 2-3mm larger than the corresponding pipe diameter (diameter). Within this range, the straight pipe meets the requirements; when the straight pipe produced cannot be placed in the groove 2 of the corresponding specification size or presents an up and down state, that is, the gap between the straight pipe and the groove 2 exceeds 4mm, the straight pipe does not meet the standard requirements. The groove 2 matches the aperture size to be measured, and the measurement of aperture sizes of different specifications can be achieved through a simple groove 2 structure, and the manufacturing cost is low.

[0044] In some feasible embodiments, chamfers are provided on the edges where the four corners of the end of the measuring body 1 are located, so as to improve the wear resistance and the aesthetics at the same time.

[0045] Example 1

[0046] A straight tube measuring tool comprises: two sections of measuring bodies 1 spliced ​​together, wherein the two sections of measuring bodies 1 have the same length, the measuring bodies 1 can be made of aluminum, the measuring bodies 1 made of aluminum are rectangular as a whole, and the cross section thereof can be rectangular, and can be made into aluminum products with dimensions of 37 mm in length, 26 mm in width, and 100 mm in height, or 37 mm in length, 26 mm in width, and 350 mm in height in two different heights; and a groove 2 is respectively provided on the bottom end face, the left side face, and the right side face of the measuring body 1, the cross section of the groove 2 is a square, and the size of each groove 2 is different, the cross section of the groove 2 is a square or a rectangle, and the size of the groove 2 is set according to the diameter of a straight tube commonly used in daily teaching, training, or competition, so as to meet the needs of daily use.

[0047] like Figure 1-3 As shown, in this embodiment, the teaching is mainly for three specifications of 1 / 4, 3 / 8, and 1 / 2, and the commonly used pipe diameter in the competition is the main measurement hole. The straight pipe measuring tool measures the straight pipe disturbance (straightness) after the students have completed the straight pipe learning. The straight pipe is made of a copper pipe. By placing the copper pipe in the groove 2 of the corresponding specification, it is confirmed whether the disturbance of the copper pipe meets the requirements, which makes the disturbance requirements of the straight pipe clearer and reduces the time of disturbance measurement, thereby improving the process of more hands-on and more learning.

[0048] The straight tube measuring tool has three grooves 2 for measuring different tube diameters, namely 1 / 4, 3 / 8, and 1 / 2 specifications of straight tubes; specifically, the groove 2 set on the bottom end surface is used to measure the straight tube of 1 / 2 diameter, and the side length of the cross section of the groove 2 on the bottom end surface is 2-3mm larger than the 1 / 2 tube diameter (diameter); the groove 2 on the left side surface is used to measure the straight tube of 3 / 8 diameter, and the side length of the cross section of the groove 2 on the left side surface is 2-3mm larger than the 3 / 8 tube diameter; the groove 2 on the right side surface is used to measure the straight tube of 1 / 4 diameter, and the side length of the cross section of the groove 2 on the right side surface is 2-3mm larger than the 1 / 4 tube diameter; by setting the three sizes of grooves 2, daily use needs can be met, and three different straight tubes can be measured at the same time.

[0049] It is conceivable that, as an alternative solution, a groove 2 of other sizes may be opened on the upper end surface of the measuring body 1 for measuring straight tubes of other sizes; the width and height of the measuring body 1 may also be increased, and multiple grooves 2 may be opened on each side, without further limitation here.

[0050] During the measurement process, the straight tube to be measured is directly placed in the groove 2 of the corresponding size, and the measurement result can be directly obtained by observing the matching relationship between the groove 2 and the straight tube; specifically, if the manufactured straight tube can be placed in the groove 2 of the corresponding size and there is no gap, it means that the straight tube is completely straight, exceeding the standard requirements; if the manufactured straight tube can be placed in the groove 2 of the corresponding size and there is a gap, and the matching tool can be inserted into the gap, it means that the straight tube meets the standard requirements; if the manufactured straight tube cannot be placed in the groove 2 of the corresponding size or presents an up and down state, that is, the gap between the straight tube and the groove 2 exceeds the deviation, it means that the straight tube does not meet the requirements.

[0051] like Figure 1-2 As shown, in the present embodiment, five recessed holes 3 are respectively provided at the ends of two adjacent measuring bodies 1, and the specific opening positions are as follows: a recessed hole 3 is respectively provided on both sides above the end face of the measuring body 1, on both sides below the end face, and in the middle of the end face, and a magnet is respectively placed in each recessed hole 3 at the ends of two adjacent measuring bodies 1, so that the two measuring bodies 1 are connected by magnet adsorption, and by providing recessed holes 3 for installing magnets at the four corner ends and the middle part, the structure is more stable when it is subsequently spliced ​​with the adjacent measuring bodies 1.

[0052] In this embodiment, the end of one of the two adjacent measuring bodies 1 provided with the concave hole 3 is provided with three clamping columns, wherein the clamping columns are not shown in the figure; the specific setting positions are: a clamping column is respectively provided on both sides of the middle part of the end of the measuring body 1 and the middle part of the upper part, and the position and number of the clamping columns can be adjusted as needed; correspondingly, the end of the other of the two adjacent measuring bodies 1 provided with the concave hole 3 is provided with three clamping grooves 4, such as Figure 2 As shown, the card slots 4 and the card columns are arranged in a one-to-one correspondence, and the assembly is completed by inserting the card columns into the corresponding card slots 4.

[0053] Chamfers are arranged on the edges at the four corners of the end of the measuring body 1, wherein the chamfers are not shown in the figure, which improves the wear resistance and the aesthetics at the same time.
