[0002] In order to facilitate the viewing of product information, existing batch products generally have a QR code engraved on the product protective cover. The QR code is located in the same position on each product, which makes it easy to view the product. Therefore, it is necessary to keep a constant distance between the QR code and the edge of the protective cover. This leads to the need to detect the position of the QR code to ensure the position of the QR code.

[0003] The existing detection method is projector detection, which has a cumbersome operation process and low detection efficiency. It also requires professionals to operate the projector, resulting in high labor and equipment costs. Therefore, in order to improve detection efficiency and simplify operation, a tool for testing the position distance of the QR code is designed. Utility Model Content

[0004] The purpose of the utility model is to provide a tool for quickly testing the position distance of a QR code, by using a first positioning boss and a second positioning boss to sequentially fit on adjacent side edges of a protective cover, so that the two adjacent edges of the QR code are sequentially located in the first viewing hole and the second viewing hole, to determine whether the QR code meets the position requirements, thereby improving the testing efficiency of the QR code and reducing the detection cost.

[0005] The utility model provides the following technical solution: a tool for quickly testing the position distance of a two-dimensional code, comprising a first measuring block and a second measuring block, wherein the first measuring block is provided with a first visual hole, and a first positioning boss is formed on the lower surface of the first measuring block, wherein one end face of the first positioning boss is located on one side of the first visual hole and is parallel to the first visual hole, and the distance from the center of the first visual hole to the end face of the first positioning boss is equal to the distance from the edge of the two-dimensional code to the side edge of the protective cover of the rotary transformer, the first positioning boss is used to cling to the side edge of the protective cover of the rotary transformer, and at the same time, the first visual hole is moved to the edge of the two-dimensional code to judge the distance of the two-dimensional code;

The distance from the center of the second visible hole to the end face of the second positioning boss is equal to the distance from the other edge of the QR code to the other side of the rotary transformer protective cover.

[0007] According to the above technical solution, waist holes are formed at both ends of the first visible hole or the second visible hole, and the waist holes are vertically distributed to the first visible hole or the second visible hole. The first visible hole or the second visible hole is calibrated by aligning the waist holes with the protective cover to ensure that there is no deviation in the first visible hole or the second visible hole on the detection tool.

[0008] According to the above technical solution, the two end surfaces of the first positioning boss are flush with the two end surfaces of the first measuring block in the length direction, which reduces the processing steps and improves the production efficiency of the first positioning boss.

[0009] According to the above technical solution, both end surfaces of the second positioning boss are located inside the two waist holes, thereby avoiding interference between the second positioning boss and the rotary transformer.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 7 , the utility model provides a technical solution: a tool for quickly testing the position distance of a two-dimensional code, comprising a first measuring block 1 and a second measuring block 3, the first measuring block 1 is provided with a first visual hole 11, and a first positioning boss 12 is formed on the lower surface of the first measuring block 1, one end face of the first positioning boss 12 is located on one side of the first visual hole 11 and is parallel to the first visual hole 11, the distance from the center of the first visual hole 11 to the end face of the first positioning boss 12 is equal to the distance from the edge of the two-dimensional code 21 to the side edge of the protective cover 22 of the rotary transformer 2, the first positioning boss 12 is used to cling to the side edge of the protective cover 22 of the rotary transformer 2 in the longitudinal direction, and at the same time, the first visual hole 11 is moved to the edge of the two-dimensional code 21 in the longitudinal direction to detect the position of the side edge of the two-dimensional code 21 in the longitudinal direction. When the edge of the two-dimensional code 21 is located in the first visual hole 11, the side position of the two-dimensional code 21 in the longitudinal direction is accurate. When the edge of the two-dimensional code 21 is not in the first visual hole 11, the position of the two-dimensional code 21 is skewed;

[0023] like Figures 5 to 7The second measuring block 3 is provided with a second visual hole 31, and a second positioning boss 32 is formed on the lower surface of the second measuring block 3. One end face of the second positioning boss 32 is located on one side of the second visual hole 31 and is parallel to the second visual hole 31. The distance from the center of the second visual hole 31 to the end face of the second positioning boss 32 is equal to the distance from the other edge of the QR code 21 to the other side edge of the protective cover 22 of the rotating transformer 2. During detection, the second positioning boss 32 is attached to the width side of the protective cover 22, and the second visual hole 31 is moved to the side edge in the width direction of the QR code 21. When the edge of the QR code 21 is located in the second visual hole 31, the side position of the QR code 21 in the width direction is accurate. Otherwise, the position of the QR code 21 has a deviation. By judging whether the edge of the QR code 21 is in the first visual hole 11 or the second visual hole 31, it is judged whether the position of the QR code 21 meets the requirements, thereby improving the detection efficiency of the position of the QR code 21 and reducing the labor cost and equipment cost.

[0024] like Figure 1 、 2 As shown in Figure 5, waist holes 4 are formed at both ends of the first visible hole 11 or the second visible hole 31. The waist holes 4 are perpendicular to the first visible hole 11 or the second visible hole 31. The waist holes 4 can be calibrated with the protective cover 22 to determine whether the first visible hole 11 is parallel to the side of the first measuring block 1, or whether the second visible hole 31 is parallel to the side of the second measuring block 3.

[0025] like Figure 2 As shown, both end surfaces of the first positioning boss 12 are flush with both end surfaces of the first measuring block 1 in the length direction, which reduces the processing steps and improves the production efficiency of the first positioning boss 12.

[0026] like Figure 5 As shown, both end surfaces of the second positioning boss 32 are located inside the two waist holes 4. By reducing the size of the second positioning boss 32, interference between the second positioning boss 32 and the rotary transformer is avoided when measuring the width edge of the two-dimensional code 21.

[0027] A guiding slope 5 is formed on the upper end of the first visual hole 11 or the second visual hole 31. The edge of the guiding slope 5 is equidistant from the first visual hole 11 or the second visual hole 31. The guiding slope 5 and the first visual hole 11 or the second visual hole 31 are on the same side, which makes it convenient to judge the position of the first positioning boss 12 or the second positioning boss 32 according to the guiding slope 5, so that the first measuring block 1 or the second measuring block 3 is tightly attached to the protective cover 22.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
