Technical Field
[0001] This utility model relates to a measuring ruler, specifically a positioning measuring ruler. Background Technology
[0002] In mid- or high-top footwear such as hiking boots, mountaineering boots, and professional work boots, the tongue and upper are often made as a single unit to provide superior protection against foreign objects and water resistance. This single-unit structure is achieved by adding winglets to both sides of the tongue and sewing these winglets to the upper. The sewing process between the winglets and the upper is a core technology in the manufacturing of these footwear types, and its quality directly affects the overall functionality of the shoe. Figure 1 The diagram shows a shoe tongue with wings, where the wings 2 are fixed to the sides of the shoe tongue 1 near the front of the shoe upper. Figure 2 The diagram shows the structure of the shoe tongue 1 combined with other parts of the upper. At this point, the front end of the shoe tongue 1 is fixed to the upper 3, and the front and back of the upper 3 are also sewn together. Next, the two side wings 2 on the shoe tongue 1 need to be sewn together with the two sides of the opening in the middle of the upper 3, so that the AB segment (from the sewing start point A to the sewing end point B) on the edge of the wing 2 is sewn onto the A'-B' segment (from the sewing start point A' to the sewing end point B') on the inside of the upper 3. In the existing sewing operation, the shoe tongue wing is first overlapped with the edge of the upper at a certain width, the edge of the AB segment on the wing is aligned with the A'-B' segment on the inside of the upper, and finally, the two are sewn together on the outside of the upper according to the existing sewing line track on one side of the A'-B' segment on the outside of the upper. This method of sewing on the outside of the shoe body is convenient for operation on sewing machines and maintains the aesthetics of the shoe's exterior. However, in practice, since A is placed on the inside of the shoe upper for sewing, determining the position of A relies on either the operator's experience or measuring the distance from the placement point of A to the edge of the shoe upper with a ruler to ensure it is the same as the distance from A' to the edge of the shoe upper. Depending on the shoe size, the distance L from A' to the edge of the shoe upper varies. A 1mm-2mm deviation in the placement of A can result in excessive or incomplete sewing of the side wing, thus affecting the finished product's pass rate. Furthermore, both methods—relying on the operator's experience or measuring the distance from the placement point of A to the edge of the shoe upper with a ruler—are inefficient.
[0003] In addition, folding techniques are frequently used in the manufacturing process of the aforementioned types of shoes, such as... Figure 2The fold 4 shown in the diagram involves sewing the fabric to the leather surface, then folding the fabric over at the sewing line, using a folding hammer to shape the fold 4, and finally sewing the edge of the fabric together. During the process, the width of the folded edge is a fixed size (generally 11mm) and must be consistent. Workers often use a ruler to measure the width of the folded fabric, and after meeting the requirements, they hammer it. Because the sewing line is generally curved rather than straight, multiple measurements and hammering are required. Each time the ruler is used, the specified length needs to be counted, making the folding operation inefficient. Utility Model Content
[0004] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a positioning measuring ruler that can accurately position the edge of the shoe tongue wing and the fold width of the hem, thereby achieving the purpose of precise sewing.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a positioning measuring ruler, comprising a ruler body, and rectangular notch-shaped locking grooves for measuring different positioning widths are formed on the corners of the ruler body, the right angle notch formed by the locking grooves and the ruler body being the positioning angle; the locking grooves include a first locking groove and a second locking groove formed on different corners of the ruler body for measuring different positioning widths, the first locking groove and the second locking groove being formed on the same side of the ruler body or on two opposite sides of the ruler body.
[0006] As a limitation of this utility model: the opening width of the first slot is 32mm and the opening depth is 3mm to 6mm, and the opening width of the second slot is 34mm and the opening depth is 3mm to 6mm.
[0007] As a limitation of this utility model: the positioning groove also includes a third positioning groove for measuring the positioning width of the folded edge, the third positioning groove having an opening width of 11mm and an opening depth of 3mm to 6mm.
[0008] As a limitation of this utility model: the surface of the ruler is marked with the width of the slot for each locking groove.
[0009] As a limitation of this utility model: the ruler body is provided with a hanging hole for threading a rope or hook.
[0010] As a limitation of this utility model, the ruler body is made of plastic or metal.
[0011] Due to the adoption of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: This utility model is a dedicated positioning measuring ruler. A positioning groove is opened at the corner of the ruler body. By using the positioning corner to clamp onto the edge of the shoe upper or a fabric of a certain thickness, the edge of the ruler body directly becomes the point to be positioned, enabling rapid positioning without the need for readings. The positioning method is direct and effective. Positioning grooves of different widths are set according to different positioning distances, and several positioning grooves can be opened on one ruler body to adapt to the measurement needs of different parts. In summary, this utility model has a simple structure, small size, and is easy to use. It can quickly and accurately position the placement of the edge of the shoe tongue wing and the fold width of the hem, improving processing efficiency and shoe quality, and is suitable for shoe manufacturing processes.

[0018] The preferred embodiments of this utility model are described below with reference to the accompanying drawings. It should be understood that the positioning measuring ruler described herein is a preferred embodiment and is only used for illustration and explanation of this utility model, and does not constitute a limitation thereof.
[0019] The directional terms or positional relationships used in this utility model are based on the directional relationships in the accompanying drawings of this utility model. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.
[0020] This implementation example Figure 3 , Figure 4 As shown, a positioning measuring ruler includes a ruler body 5, which is plate-shaped. The material of the ruler body 5 can be plastic or metal with a certain degree of hardness, forming a thin plate shape.
[0021] like Figure 3 , Figure 4 As shown, rectangular notches for measuring different positioning widths are formed at the corners of the ruler body 5. Before the notches are formed, the ruler body is rectangular; after the notches are formed, it becomes polygonal. The two sides of the rectangular notches are open, and the right-angle notches formed by the notches and the ruler body 5 create a positioning angle 54. Depending on the measurement requirements, the notches include a first notch 51 and a second notch 52, located at different corners of the ruler body 5, for measuring different positioning widths. The first notch 51 and the second notch 52 are located on the same side of the ruler body 5 or on two opposite sides of the ruler body 5. The notches also include a third notch 53 for measuring the positioning width of the folded edge. Specifically, the first notch 51 has a width of 32mm and a depth of 3mm to 6mm; the second notch 52 has a width of 34mm and a depth of 3mm to 6mm; and the third notch 53 has a width of 11mm and a depth of 3mm to 6mm. In this embodiment, the preferred depth is 5mm. The first slot 51, with a width of 32mm, is used to measure the placement of the edge of the tongue wing on a shoe with a smaller shoe size, and the second slot 52, with a width of 34mm, is used to measure the placement of the edge of the tongue wing on a shoe with a larger shoe size. Of course, the width of each slot is determined based on actual usage.
[0022] To make it more convenient, quick, and accurate to use, the width of each slot is marked on the surface of the ruler body 5 where each slot is located. In addition, there are hanging holes 55 on the ruler body 5 for threading ropes or hooks, so that the ruler body 5 can be hung on the wrist for convenient use at any time.
[0023] When using this embodiment, select a suitable positioning groove, place the ruler 5 on the inside of the shoe upper, and place the positioning angle 54 of the positioning groove on the edge of the shoe upper. The edge of the ruler 5 is where the sewing start point A should be placed. After determining point A, first sew and fix point A, then determine point B in the same way, temporarily fix the position of the wing by hand, and finally sew the two together along the existing sewing line track of section A'-B'. When positioning the folded edge, fold the fabric over, use the third positioning groove 53 to position the width of the folded fabric, and after the width is met, use a folding hammer to hammer and shape it. Repeat the positioning operation until the entire folded edge is shaped, and finally sew the edge of the fabric.
