Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, in particular to a flatness measuring device. Background Art

[0002] The shoe last, a traditional Chinese shoemaking tool, is the mother of the shoe, the mold that forms the shoe. It not only determines the shape and style of the shoe, but also its fit and foot protection. Therefore, shoe last design must be based on the foot's shape, but it cannot be identical to the foot itself. This is because the foot's shape, size, and stresses vary both at rest and in motion. Furthermore, shoe types, styles, processing techniques, raw material properties, and wearing environments and conditions vary. Therefore, the shape and dimensions of each component of the shoe last cannot be exactly the same as the foot itself. Therefore, modern shoe last design involves multiple disciplines and requires a high level of craftsmanship and experience.

[0003] When walking in shoes, both comfort and stability must be ensured. Therefore, the sole design of the shoe must be flat so that the force on the sole of the foot is evenly distributed. The shoe last, as a tool that affects the size of the shoe, must meet the flatness requirement. That is, the bottom of the shoe last needs to have several balance points on the same horizontal plane. Therefore, it is necessary to propose a flatness measuring device that can quickly measure the flatness of the bottom of the shoe last. Utility Model Content

[0004] The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art and to provide a flatness measuring device. The measuring device of the present invention can quickly measure the flatness of the bottom surface of a shoe last through a streamlined structure, that is, two front plane columns and two rear plane columns located on one side of the measuring tool body form four balance points on the same horizontal plane.

[0005] The technical solution adopted by the present invention is as follows: a flatness measuring device includes a measuring tool body, and a front foot measuring block and a rear foot measuring block are respectively provided at both ends of the measuring tool body. The front foot measuring block and the rear foot measuring block are relatively parallel and are both arranged relatively perpendicular to the measuring tool body. At least two front plane columns are raised on the front foot measuring block, and at least two rear plane columns are raised on the rear foot measuring block. The end surfaces of the two front plane columns and the two rear plane columns away from the measuring tool body are simultaneously on the same horizontal plane.

[0006] The two front plane columns are distributed at both ends of the front foot measurement block, and the two rear plane columns are distributed at both ends of the rear foot measurement block. The distance between the two front plane columns is greater than the distance between the two rear plane columns.

[0007] Two front plane columns are protruded from the symmetrical positions on the other side of the two front plane columns on the front foot measuring block, and two rear plane columns are protruded from the symmetrical positions on the other side of the two rear plane columns on the rear foot measuring block. The two front plane columns and the two rear plane columns on the same side of the measuring tool body are on the same horizontal plane at the same time.

[0008] A slot is recessed in the middle of both sides of the forefoot measuring block and the rearfoot measuring block, and four blocks protrude from the measuring tool body, which correspond to and are engaged with the four slots one by one, and each block has an interference fit with the corresponding slot.

[0009] A first arc surface and a second arc surface are respectively recessed on both sides of the measuring tool body, and the curvature of the first arc surface is greater than that of the second arc surface.

[0010] The measuring tool body is a flat plate structure, and an end surface of the measuring tool body is penetrated by two positioning holes.

[0011] The measuring tool body, the front foot measuring block and the rear foot measuring block are all made of stainless steel.

[0012] The beneficial effects of the present invention are as follows: the measuring device of the present invention can quickly measure the flatness of the bottom surface of the shoe last through a streamlined structure, that is, the two front plane columns and the two rear plane columns located on one side of the measuring tool body form four balance points on the same horizontal plane. By simultaneously fitting the four balance points to the bottom of the shoe last, it is possible to quickly judge whether the flatness of the bottom surface of the shoe last is qualified. If all four balance points are fitted to the bottom surface of the shoe last, the flatness of the bottom surface of the shoe last is qualified. The four-point support measurement method has the advantages of accurate measurement results and stable measurement. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The directional and positional terms used in this invention, such as "upper," "lower," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are used solely to refer to the directions or positions in the accompanying drawings. Therefore, the directional and positional terms used are intended to illustrate and facilitate understanding of this invention and are not intended to limit the scope of protection of this invention.

[0021] like Figures 1 to 3 As shown in the figure, an embodiment of the present invention is a flatness measuring device, comprising a measuring tool body 1, with a forefoot measuring block 2 and a rearfoot measuring block 3 provided at both ends of the measuring tool body 1, the forefoot measuring block 2 and the rearfoot measuring block 3 being relatively parallel and both being arranged relatively perpendicular to the measuring tool body 1, at least two front plane columns 4 protruding from the forefoot measuring block 2, and at least two rear plane columns 5 protruding from the rearfoot measuring block 3, the two front plane columns 4 and the two rear plane columns 5 being located on the same horizontal plane at the end surface away from the measuring tool body 1.

[0022] The beneficial effects of such a setting are as follows: the measuring device of the present invention can quickly measure the flatness of the bottom surface of the shoe last through a streamlined structure, that is, the two front plane columns and the two rear plane columns located on one side of the measuring tool body form four balance points on the same horizontal plane. By simultaneously fitting the four balance points with the bottom of the shoe last, it is possible to quickly judge whether the flatness of the bottom of the shoe last is qualified. If all four balance points are fitted with the bottom of the shoe last, the flatness of the bottom of the shoe last is qualified. The four-point support measurement method has the advantages of accurate measurement results and stable measurement.

[0023] It is further configured that the two front plane columns 4 are distributed at both ends of the front foot measurement block 2, the two rear plane columns 5 are distributed at both ends of the rear foot measurement block 3, and the distance between the two front plane columns 4 is greater than the distance between the two rear plane columns 5.

[0024] The beneficial effects of this arrangement are as follows: the spacing between the two front plane columns is greater than the spacing between the two rear plane columns, which is more suitable for the wider shape structure of the forefoot of the shoe last, and makes it easier to distinguish between the forefoot and the rearfoot, further improving measurement efficiency.

[0025] It is further configured that two front plane columns 4 are protruded from the symmetrical positions on the other side of the two front plane columns 4 on the front foot measuring block 2, and two rear plane columns 5 are protruded from the symmetrical positions on the other side of the two rear plane columns 5 on the rear foot measuring block 3. The two front plane columns 4 and the two rear plane columns 5 on the same side of the measuring tool body 1 are on the same horizontal plane at the same time.

[0026] This arrangement has the following beneficial effects: Four balance points are located on each side of the measuring tool body, allowing for measurements from both sides. This makes it suitable for both feet and expands its range of use. The combined length of the upper and lower front planar columns of the forefoot measuring block, and therefore the overall height of the measuring device, ranges from 45 to 65 mm. In this embodiment, a height of 55 mm is used, which is optimal for measurement and facilitates observation of gaps between the bottom surface of the shoe last and the planar columns. The measuring tool body is 130 mm long, with a width of 65 mm at the end where the forefoot measuring block is mounted, and a width of 40 mm at the end where the rear foot measuring block is mounted, to match the shape of the shoe last.

[0027] It is further provided that a slot 6 is recessed in the middle of both sides of the forefoot measuring block 2 and the rear foot measuring block 3, and four blocks 7 are raised on the measuring tool body 1, which correspond to and are engaged with the four slots 6 one by one, and each of the blocks 7 is interference fit with the corresponding slot 6.

[0028] The beneficial effects of such an arrangement are as follows: the detachable structure is convenient for assembly and disassembly, convenient for production and processing, and also saves materials.

[0029] It is further provided that a first arc surface 8 and a second arc surface 9 are respectively recessed on both sides of the measuring tool body 1 , and the curvature of the first arc surface 8 is greater than that of the second arc surface 9 .

[0030] The beneficial effects of this arrangement are as follows: the outer structure is more compatible with the shoe last, and the left and right feet can be distinguished. In addition, the curved surfaces on both sides of the measuring tool body are more conducive to holding, thereby improving the comfort of holding the measuring tool.

[0031] It is further provided that the measuring tool body 1 is a flat plate structure, and two positioning holes 10 are passed through the end surface of the measuring tool body 1.

[0032] The beneficial effects of this arrangement are as follows: when storing the measuring device, two cylinders or cones can be inserted into the two positioning holes respectively, so that the measuring device is raised and does not contact the ground, and the measuring device will not rotate, reducing the risk of deformation of the front plane column and the rear plane column due to external collisions and improving the service life.

[0033] It is further provided that the measuring tool body 1, the front foot measuring block 2 and the rear foot measuring block 3 are all made of stainless steel.

[0034] The beneficial effects of this setting are as follows: the stainless steel material has high hardness, stronger deformation resistance and longer service life.

[0035] According to different data of the measuring tool, shoe lasts of different sizes can be measured, such as men's shoes, women's shoes, and children's shoes.

[0036] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
