AI Technical Summary
Existing profile gauges are prone to errors when reading dimensions, and cannot directly read dimensions based on the contact area with the object being measured.
Multiple thin inserts were designed, with K thin inserts between each pair of adjacent color markings, where K is an integer ≥1. The total thickness of the K thin inserts is an integer multiple of D. The color markings extend to the size scale area, allowing for quick reading of the measured dimensions by combining the color markings and the size scale.
By combining color-coded markings and scale areas, more intuitive and accurate dimension readings are achieved, reducing manufacturing difficulty and improving positioning accuracy.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of measuring tools, and in particular to a profile gauge. Background Technology
[0002] Existing profilometry structures, such as those shown in CN211710493U, typically include a housing and a thin insert movably mounted on the housing. The thin insert achieves profilometry by contacting the contour of the object being measured. However, in existing profilometry, the dimensional scale is located on the housing, and while the thin insert uses the same specifications, its thickness is not standard. This makes it impossible to directly read dimensions based on the contact point with the object being measured, easily leading to dimensional reading errors. Summary of the Invention
[0003] To address the aforementioned problems, the purpose of this invention is to provide a square gauge that offers greater accuracy in dimension reading.
[0004] A contour guide includes a housing and multiple thin inserts movably mounted on the housing. The thin inserts are arranged close together and laid out laterally in a row for contour contouring. The surface of the housing is provided with a dimensional scale area, the minimum scale interval of which is D.
[0005] In rows of thin inserts, color markings are set at intervals, and there are K thin inserts between each pair of adjacent color markings, where K is an integer ≥1;
[0006] The total thickness of the K thin inserts is an integer multiple of D;
[0007] The color markings extend into the size scale area, and adjacent color markings are the same size.
[0008] Using the above scheme, the thickness of the thin inserts is set according to the aforementioned dimensions. Since the distance between adjacent color markings is fixed, such as 0.5cm or 1cm, and the color markings extend into the size scale area, the measurement dimensions can be quickly read by combining the color markings and the size scale. Furthermore, color markings extending into the size scale area are spaced apart among the rows of thin inserts. The positions of the color markings can correspond to the 5mm or 1cm lines of the size scale area, allowing for a more intuitive reading of the specific scale dimensions during measurement.
[0009] Preferably, the edges of the thin inserts are aligned with the scale lines of the dimensional marking area. Each thin insert has the same thickness; by setting the thickness of each individual thin insert, it is possible to ensure that the edges of the thin inserts are always aligned with the scale lines of the dimensional marking area. For example, the thickness of a single thin insert can be D / N or D*N, thus ensuring that the edges of the thin inserts are always aligned with the scale lines, facilitating scale reading.
[0010] Preferably, the thickness of a single thin insert is the same as the minimum scale mark of the dimensional scale area. Since excessively thin inserts are prone to deformation and are more difficult to manufacture, this design reduces the manufacturing difficulty of the thin inserts while ensuring easy reading of dimensions, and also allows the edges of the thin inserts to align with the scale lines.
[0011] Preferably, the color markings include a first color marking and a second color marking set at intervals. As described above, the spacing between adjacent markings of the same color is a fixed size, and the spacing between adjacent markings of different colors is another fixed size. This facilitates more intuitive reading of the dimensions, and the contrasting color design avoids misreading compared to using the same color.
[0012] Preferably, the minimum scale interval D in the size scale area is 1mm, the thickness of a single thin insert is 1mm, and the spacing between adjacent color markings is 5mm. These settings correspond to the size settings of a conventional ruler.
[0013] Preferably, the longitudinal end of the thin insert includes a first positioning portion and a second positioning portion. The first positioning portion extends in a front-to-back direction, and the second positioning portion extends obliquely rearward from the rear end of the first positioning portion. The included angle between the first positioning portion and the second positioning portion is greater than 90°. With the above configuration, when contouring using the thin insert, contouring can be performed using either the first positioning portion or the second positioning portion, depending on the shape of the measured position of the object being measured. Furthermore, for contouring, for example, curved surfaces, the included angle between the first and second positioning portions allows for better contact with the surface to be measured, which helps improve the positioning accuracy of the thin insert in contouring.

[0017] The embodiments of this utility model are described in detail below.
[0018] This embodiment provides a contour guide, including a housing 1 and a plurality of thin inserts 2 movably disposed on the housing 1. The plurality of thin inserts 2 are disposed close together and arranged horizontally in a row for contour contouring. The connection method between the housing 1 and the thin inserts 2 is a conventional technique in the art. The improvement of this solution lies in the arrangement of the thin inserts 2, which will be described in detail later.
[0019] The surface of the housing 1 is provided with a size scale area. The minimum scale interval of this size scale area is D, which is usually 1mm. The size values are marked by longer scale lines every 5mm and 10mm to facilitate reading.
[0020] like Figure 1 As shown, in the rows of thin inserts 2, color markers are spaced apart, and each pair of adjacent color markers contains K thin inserts 2, where K is an integer ≥ 1; the total thickness of the K thin inserts 2 is an integer multiple of D. Therefore, the dimension between adjacent color markers is a definite and readable value. For example, in one specific embodiment, D is 1 mm, the thickness between two adjacent color markers is 5 mm, the thickness of a single thin insert 2 is 1 mm, and K is 5; or the thickness of a single thin insert 2 is 1.25 mm, and K is 4; or the thickness of a single thin insert 2 is 0.5 mm, and K is 10. Similarly, K and the thickness of a single thin insert 2 can take other values.
[0021] In a preferred embodiment, the edge of the thin insert 2 is aligned with the scale line of the dimensional scale area. By setting the thickness of a single thin insert 2, the edge of the thin insert 2 in a row is always aligned with the scale line of the scale area, thereby avoiding reading errors caused by the center of the thin insert 2 being aligned with the scale line.
[0022] In a preferred embodiment, the thickness of a single thin insert 2 is the same as the minimum scale mark of the dimensional scale area. Since excessively thin inserts are prone to deformation and are more difficult to manufacture, this method reduces the manufacturing difficulty of the thin insert 2 while ensuring easy reading of dimensions, and also allows the edges of the thin insert 2 to align with the scale lines.
[0023] Preferably, the minimum scale interval D in the size scale area is 1mm, the thickness of a single thin insert 2 is 1mm, and the spacing between adjacent color markings is 5mm. This setting corresponds to the scale markings of conventional rulers on the market.
[0024] In this embodiment, one side of the color mark extends to the size scale area, and the other side extends to the end of the thin insert 2 in the longitudinal direction, with adjacent color marks having the same size. The color marks extend in this manner, directly connecting the surface of the object being measured and the size scale area, facilitating size reading. In a preferred embodiment, the color marks include a first color mark 3 and a second color mark 4 spaced apart. The first color mark 3 and the second color mark 4 are different colors; this contrasting color design avoids misreading compared to using the same color.
[0025] In addition, such as Figure 1As shown, the longitudinal end of the thin insert 2 includes a first positioning portion 21 and a second positioning portion 22. The first positioning portion 21 extends in the front-rear direction, and the second positioning portion 22 extends obliquely rearward from the rear end of the first positioning portion 21. The included angle between the first positioning portion 21 and the second positioning portion 22 is greater than 90°. With the above configuration, when contouring using the thin insert 2, contouring can be performed using either the first positioning portion 21 or the second positioning portion 22, depending on the shape of the measured position of the object being measured. Especially when used for contouring, for example, curved surfaces, the angle between the first positioning portion 21 and the second positioning portion 22 allows for better contact with the surface to be measured, which helps improve the positioning accuracy of the thin insert 2 in contouring.
[0026] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
