Description

Technical Field

[0001] The utility model relates to the technical field of shoe last measuring devices, in particular to a portable four-point flat measuring device for shoe lasts. Background Art

[0002] "Four-point flatness" is a key concept in shoe last design and manufacturing. It's based on ergonomic principles and aims to ensure comfort and stability. This refers to the requirement that four key points on the sole of the shoe last be aligned during last design to maintain proper alignment. These four points are: the heel center, the heel lateral point, the first metatarsophalangeal point, and the fifth metatarsophalangeal point. During the last manufacturing process, technical inspections are performed to verify the alignment of the last, including checking for "four-point flatness."

[0003] In the existing technology, the instruments commonly used to check the "four-point flatness" are relatively bulky and the measurement process is cumbersome. Non-professionals need appropriate training to master them, which is difficult to use. At the same time, the commonly used instruments are large in size and have a relatively complex structure. Therefore, they are not portable and cannot be carried conveniently, which limits their usage scenarios. Therefore, to address the above problems, a portable shoe last four-point flatness measuring device is proposed. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a portable four-point flatness measuring device for a shoe last. The shoe last measuring device is simple to operate and has almost no usage threshold. When in use, the measuring device only needs to be placed on the shoe last so that the bottom end points of the four needle posts are aligned with the four detection points. If the bottom end of any one of the needle posts does not contact the shoe last, it means that the shoe last is not straight. In addition, the measuring device has a simple structure, a compact size, and is easy to carry. The needle posts can be removed and fixed on an adsorption storage member when carrying, further reducing the space occupied, making it easy for users to carry it with them, and broadening its usage scenarios. It solves the technical problems in the prior art that the detection mechanism is relatively bulky and the measurement process is cumbersome, which has a certain degree of difficulty in getting started, and the portability is poor, which limits its usage scenarios.

[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0006] A portable four-point flatness measuring device for a shoe last comprises a base plate, a wide end of which serves as a sole measuring end, a narrow end as a heel measuring end, needle posts detachably mounted at the four corners of the base plate via bolt connectors, i.e., needle posts are mounted on both sides of the sole measuring end and on both sides of the heel measuring end, and an adsorption storage member for securing the removed needle posts when the measuring device is carried. The four needle posts are of the same length, and after being mounted and fixed, the bottom ends of the four needle posts are all in the same plane. During inspection, the measuring device is placed as a whole on the shoe last so that the bottom ends of the four needle posts are aligned with the four detection points. Since the bottom ends of the four needle posts are all in the same plane, if the bottom end of any one of the needle posts is not in contact with the shoe last, it indicates that the shoe last is not straight.

[0007] In a possible implementation, corner mounting grooves are provided at the four corners of the substrate, and threaded holes are provided in the corner mounting grooves. The above-mentioned structural form provides the necessary structural basis for the positioning and fixed installation of the needle column.

[0008] In one possible implementation, a card slot matching the size of the corner mounting slot is provided in the middle of the needle column. When installing the needle column, the card slot is engaged with the corner mounting slot, which plays a positioning role in the installation of the needle column, ensuring that the four needle columns can maintain a uniform position after installation, thereby ensuring the accuracy of the measurement. At the same time, a connecting hole connected to the card slot and corresponding to the threaded hole is provided in the middle of the needle column. When connecting, the bolt connector passes through the connecting hole and is threadedly connected to the threaded hole. This structural form can realize a detachable connection between the needle column and the base plate.

[0009] In one possible implementation, a countersunk hole is formed at the outer end of the connecting hole, and the size of the countersunk hole corresponds to the size of the nut of the bolt connector. The opening of the countersunk hole enables the end cap of the bolt connector to be located in the countersunk hole without protruding after being tightened.

[0010] In a possible implementation, the needle column includes an iron cylinder with cone heads fixedly connected to both the upper and lower ends. The cone heads are conical in shape. The above structure provides the necessary structural basis for the fixed installation and detection of the needle column.

[0011] In one possible implementation, the vertical distance between the two needle posts at the sole measurement end of the substrate is 75 mm, and the vertical distance between the two needle posts at the heel measurement end is 48 mm. The above control dimensions correspond to the minimum width of the corresponding position of the national standard foot shape data, ensuring that the control dimensions can be applied to the measurement of shoe lasts of any size.

[0012] In one possible implementation, the adsorption storage component includes a storage plate with a plurality of storage slots formed thereon, wherein an arc-shaped magnet sheet is embedded in the slot and connected thereto, and the size of the arc-shaped magnet sheet matches the size of the cylinder. When the needle column needs to be carried and removed, the needle column is clamped in the arc-shaped magnet sheet and adsorbed and fixed by it. At the same time, a centrally arranged anti-slip positioning protrusion is fixed on the arc-shaped magnet sheet, and the size of the anti-slip positioning protrusion matches the size of the slot. The anti-slip positioning protrusion can be clamped with the slot to position the needle column and prevent the needle column from sliding in the arc-shaped magnet sheet. When stored, the cone head outer sleeve is provided with a needle cover, which can cover the cone head to prevent it from injuring the user.

[0013] In one possible implementation, buckle plates and card plates are fixedly provided on both sides of the lower end surface of the storage plate, both of which can fit with the side of the substrate, wherein the buckle plates are elastic plates, and the bottom end of which is fixedly connected to an anti-slip plate. When the adsorption storage part is installed, the buckle plates are deformed and opened. When the adsorption storage part is fully installed, the buckle plates return to their original shape and hold the substrate through the anti-slip plate to prevent the adsorption storage part from falling off. The bottom end of the card plate is processed to form a chamfer, and the card plate can play a supporting role by fitting with the side of the substrate to prevent the adsorption storage part from shaking after installation.

[0014] In summary, the present invention has the following beneficial technical effects:

[0015] The shoe last measuring device is easy to operate and has almost no usage threshold. When in use, the measuring device only needs to be placed on the shoe last so that the bottom end points of the four needle posts are aligned with the four detection points. If the bottom end of any needle post does not contact the shoe last, it means that the shoe last is not straight. In addition, the measuring device has a simple structure and a compact size, which is easy to carry. When carrying, the needle posts can be removed and fixed on an adsorption storage piece, further reducing the space occupied. It can be convenient for users to carry it with them, broadening its usage scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0024] like Figure 1 As shown, the present embodiment provides a portable four-point flatness measuring device for a shoe last, comprising a base plate 1, a wide end of which is a sole measuring end, and a narrow end of which is a heel measuring end, needle posts 2, which are detachably mounted at the four corners of the base plate 1 via bolt connectors 3, i.e., needle posts 2 are mounted on both sides of the sole measuring end, and needle posts 2 are mounted on both sides of the heel measuring end, and an adsorption storage member 4, which is used to fix the removed needle posts 2 when the measuring device is carried. The four needle posts 2 are of the same length, and the bottom ends of the four needle posts 2 are in the same plane after being mounted and fixed. During inspection, the measuring device is placed as a whole on the shoe last so that the bottom ends of the four needle posts 2 are aligned with the four detection points. Since the bottom ends of the four needle posts 2 are in the same plane, if the bottom end of any one of the needle posts 2 is not in contact with the shoe last, it means that the shoe last is not straight.

[0025] like Figure 2 As shown, corner mounting grooves 11 are provided at the four corners of the base plate 1 , and threaded holes 12 are provided in the corner mounting grooves 11 . The above-mentioned structural form provides the necessary structural basis for the positioning and fixed installation of the needle column 2 .

[0026] Correspondingly, a card slot 22 matching the size of the corner mounting slot 11 is provided in the middle of the needle column 2. When the needle column 2 is installed, the card slot 22 is engaged with the corner mounting slot 11, which plays a positioning role in the installation of the needle column 2, ensuring that the four needle columns 2 can maintain a uniform position after installation, thereby ensuring the accuracy of the measurement. At the same time, a connecting hole 21 connected to the card slot 22 and corresponding to the threaded hole 12 is provided in the middle of the needle column 2. When connected, the bolt connector 3 passes through the connecting hole 21 and is threadedly connected to the threaded hole 12. This structural form can realize a detachable connection between the needle column 2 and the base plate 1.

[0027] In addition, a countersunk hole 23 is formed at the outer end of the connecting hole 21, and the size of the countersunk hole 23 corresponds to the size of the nut of the bolt connector 3. The opening of the countersunk hole 23 allows the end cap of the bolt connector 3 to be located in the countersunk hole 23 without protruding after being tightened.

[0028] like Figure 2 As shown, the needle column 2 includes an iron cylinder 201, with cone heads 202 fixedly connected to both the upper and lower ends. The cone head 202 is conical. The above structure provides the necessary structural basis for the fixed installation and detection of the needle column 2.

[0029] like Figure 3-Figure 5 As shown, the adsorption storage part 4 includes a storage plate 41, which is provided with a plurality of storage slots 42, and an arc-shaped magnet sheet 43 is embedded in the slot. The size of the arc-shaped magnet sheet 43 matches the size of the cylinder 201. When the needle column 2 needs to be carried and removed, the needle column 2 is clamped in the arc-shaped magnet sheet 43 and adsorbed and fixed by it. At the same time, a centrally arranged anti-slip positioning protrusion 44 is fixed on the arc-shaped magnet sheet 43, and the size of the anti-slip positioning protrusion 44 matches the size of the slot 22. The anti-slip positioning protrusion 44 can be mutually engaged with the slot 22, which plays a positioning role for the placement of the needle column 2 and can also prevent the needle column 2 from sliding in the arc-shaped magnet sheet 43. When stored, the cone head 202 is provided with a needle cover 5 on the outer shell, and the needle cover 5 can cover the cone head 202 to prevent it from injuring the user.

[0030] In addition, buckle pieces 45 and card plates 46 are fixedly provided on both sides of the lower end surface of the storage plate 41, both of which can fit with the side of the substrate 1, wherein the buckle piece 45 is an elastic sheet, and its bottom end is fixedly connected to the anti-slip plate 451. When the adsorption storage part 4 is installed, the buckle piece 45 is deformed and opened. When the adsorption storage part 4 is fully installed, the buckle piece 45 returns to its original shape and buckles the substrate 1 through the anti-slip plate 451 to prevent the adsorption storage part 4 from falling off. The bottom end of the card plate 46 is processed to form a chamfer 461, and the card plate 46 can play a supporting role by fitting with the side of the substrate 1 to prevent the adsorption storage part 4 from shaking after installation.

[0031] In order to expand the scope of application of the measuring instrument, Figure 1 As shown, the vertical distance between the two needle posts 2 at the sole measurement end of the base plate 1 is 75 mm, and the vertical distance between the two needle posts 2 at the heel measurement end is 48 mm. The above control dimensions correspond to the minimum width at the corresponding position of the national standard foot shape data, ensuring that the control dimensions are applicable to the measurement of shoe lasts of any size.

When using it, one only needs to place the measuring device as a whole on the shoe last so that the bottom end points of the four needle posts 2 are aligned with the four detection points. Since the bottom end points of the four needle posts 2 are all in the same plane, if the bottom end of any one of the needle posts 2 is not in contact with the shoe last, it means that the shoe last is not straight.

[0034] In addition, the measuring device has a simple structure, a compact size, and is easy to carry. When carrying, the needle column 2 can be removed and fixed on the adsorption storage part 4, further reducing the space occupied, making it convenient for users to carry it with them and broadening its usage scenarios.

At the same time, a centrally arranged anti-slip positioning protrusion 44 is fixed on the arc-shaped magnet sheet 43, and the size of the anti-slip positioning protrusion 44 matches the size of the card slot 22. The anti-slip positioning protrusion 44 can be mutually engaged with the card slot 22, which plays a positioning role in the placement of the needle column 2 and can also prevent the needle column 2 from sliding in the arc-shaped magnet sheet 43. In addition, when storing, the cone head 202 is provided with a needle cover 5 on the outer cover, and the needle cover 5 can cover the cone head 202 to prevent it from injuring the user.
