Description

Technical Field

[0001] This utility model relates to the field of diameter measurement technology, specifically to a digital diameter ruler. Background Technology

[0002] Traditional measuring tools, such as calipers and micrometers, while meeting basic length measurement needs, have limitations when measuring diameters, especially larger ones. For example, ordinary calipers have a limited measuring range and cannot directly measure larger objects, and require additional adapters or complex operations when measuring inner diameters. Furthermore, traditional measuring tools mostly rely on manual reading of the scale, which is prone to measurement errors due to human factors, especially in high-precision measurement scenarios, where such errors can affect the accuracy of the measurement results.

[0003] With the development of industrial manufacturing and precision machining technologies, the demand for high-precision, wide-range diameter measurement is increasing. For example, in fields such as machining, aerospace, and automotive manufacturing, it is necessary to accurately measure the inner and outer diameters of various components to ensure they meet design requirements. Traditional measuring tools are no longer sufficient to meet these high-precision, wide-range measurement needs. Therefore, developing a digital diameter gauge that can simultaneously meet the requirements of high precision and wide-range measurement, while also being easy to operate and providing intuitive readings, is particularly important. Utility Model Content

[0004] This invention proposes a digital display diameter ruler, which solves the problem that existing equipment cannot meet the requirements of these high-precision, large-range measurements.

[0005] The technical solution of this utility model is as follows:

[0006] A digital diameter ruler includes a first main scale and a slide ruler slidably disposed on the first main scale. The first main scale has a first measuring scale, and the slide ruler has a second measuring scale. After the slide ruler slides on the first main scale, it is used to measure the distance between the first measuring scale and the second measuring scale.

[0007] The slide ruler is equipped with a display component for displaying the distance between the first measuring ruler and the second measuring ruler;

[0008] The first main scale has a groove, and a second main scale is slidably disposed in the groove. After the second main scale slides in the groove, it is used to increase the measuring length of the first measuring scale and the second measuring scale.

[0009] As a further technical solution, the slide groove is a through groove along the sliding direction perpendicular to the second main scale;

[0010] The sliding ruler includes a front ruler and a rear ruler, which are connected by bolts. After the front ruler and the rear ruler are connected, they are slidably mounted on the first main ruler and the second main ruler. It also includes clamping components respectively mounted on the front ruler and the rear ruler for clamping the first main ruler and the second main ruler.

[0011] As a further technical solution, both the first and second main scales have guide grooves. The clamping assembly includes several guide wheels that are rolled in the guide grooves, and also includes an elastic element with one end set on the front or rear scale and the other end set on a guide wheel. The elastic element is used to provide the force for the guide wheel to abut against the guide groove.

[0012] As a further technical solution, a set screw is also included. The set screw thread is set on the slide. After the set screw rotates on the slide, it is used to clamp the first main scale or the second main scale.

[0013] As a further technical solution, the slide ruler is also provided with a first inner diameter ruler, and the end of the first main ruler is provided with a second inner diameter ruler. The distance between the first inner diameter ruler and the second inner diameter ruler is the same as the distance between the first measuring ruler and the second measuring ruler, and the first inner diameter ruler and the second inner diameter ruler are arranged opposite to each other, and the abutting ends of the first measuring ruler and the second measuring ruler are arranged facing each other.

[0014] As a further technical solution, the display component includes a display screen disposed on the front scale, and a sensor disposed on the front scale for sliding with the front scale, the sensor and the display screen being electrically connected.

[0015] As a further technical solution, the display assembly also includes a power switch and a zeroing switch disposed on the front scale for electrical connection with the sensor and the display screen, and a power supply battery disposed on the front scale for powering the sensor and the display screen.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] In this invention, the first main scale is a long, narrow ruler with a first measuring scale mounted on it. A sliding scale is mounted on the first main scale via a precise sliding mechanism, allowing it to slide smoothly along the length of the first main scale. A second measuring scale is mounted on the sliding scale. As the sliding scale slides, a certain distance is formed between the first and second measuring scales, which can be visually displayed by a display component on the sliding scale. Furthermore, the first main scale has a groove whose dimensions match the second main scale, allowing the second main scale to slide freely within the groove. When measuring objects with larger diameters, the second main scale is pulled out of the groove. By sliding the second main scale, the measuring length range of both the first and second measuring scales can be significantly increased, thus meeting the measurement needs of objects of different sizes and greatly improving the applicability and measuring range of the digital diameter ruler.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] Example

[0025] like Figures 1-3 As shown, a digital diameter ruler includes a first main scale 1 and a sliding scale 2 slidably disposed on the first main scale 1. The first main scale 1 has a first measuring scale 3, and the sliding scale 2 has a second measuring scale 4. After the sliding scale 2 slides on the first main scale 1, it is used to measure the distance between the first measuring scale 3 and the second measuring scale 4.

[0026] The sliding ruler 2 is equipped with a display component 5 for displaying the distance between the first measuring ruler 3 and the second measuring ruler 4;

[0027] The first main ruler 1 has a groove 6, and a second main ruler 7 is slidably disposed in the groove 6. After the second main ruler 7 slides in the groove 6, it is used to increase the measuring length of the first measuring ruler 3 and the second measuring ruler 4.

[0028] In this embodiment, the first main ruler 1 is a long strip-shaped ruler with a first measuring ruler 3 mounted on it. A sliding ruler 2 is mounted on the first main ruler 1 via a precise sliding mechanism, allowing it to slide smoothly along the length of the first main ruler 1. A second measuring ruler 4 is mounted on the sliding ruler 2. When the sliding ruler 2 slides, a certain distance is formed between the first measuring ruler 3 and the second measuring ruler 4, which can be visually displayed by the display component 5 on the sliding ruler 2. Furthermore, the first main ruler 1 has a groove 6, the size of which matches the second main ruler 7, allowing the second main ruler 7 to slide freely within the groove 6. When measuring objects with larger diameters, the second main ruler 7 is pulled out of the groove 6. By sliding the second main ruler 7, the measurement length range of the first measuring ruler 3 and the second measuring ruler 4 can be significantly increased, thereby meeting the measurement needs of objects of different sizes and greatly improving the applicability and measurement range of the digital diameter ruler.

[0029] Furthermore, the slide 6 is a through groove along the sliding direction perpendicular to the second main scale 7;

[0030] The sliding ruler 2 includes a front ruler 8 and a rear ruler 9, which are connected by bolts. After the front ruler 8 and the rear ruler 9 are connected, they are slidably mounted on the first main ruler 1 and the second main ruler 7. It also includes a clamping assembly 10, which is respectively mounted on the front ruler 8 and the rear ruler 9 for clamping the first main ruler 1 and the second main ruler 7.

[0031] In this embodiment, the slide groove 6 of the digital display diameter ruler is designed as a through groove perpendicular to the sliding direction of the second main scale 7, penetrating the entire length of the first main scale 1. The slide 2 consists of a front scale 8 and a rear scale 9, which are connected by bolts to form an integral structure. After the front scale 8 and the rear scale 9 are connected, they can slide simultaneously on the first main scale 1 and the second main scale 7, thereby achieving flexible adjustment of the measurement range. To ensure the stability and accuracy of the measurement, a clamping component 10 is provided on the front scale 8 and the rear scale 9 of the slide 2. The clamping component 10 can firmly clamp the first main scale 1 and the second main scale 7, preventing the slide 2 from loosening or slipping during the measurement process. This design not only improves the reliability of the measurement but also allows the slide 2 to be quickly fixed after the position is adjusted, facilitating accurate measurement by the user.

[0032] Furthermore, both the first main scale 1 and the second main scale 7 have guide grooves 11. The clamping assembly 10 includes several guide wheels 12 that are rolled in the guide grooves 11, and also includes an elastic element 13 with one end set on the front scale 8 or the rear scale 9 and the other end set on a guide wheel 12. The elastic element 13 is used to provide the force for the guide wheel 12 to abut against the guide groove 11.

[0033] In this embodiment, guide grooves 11 are provided on both the first main scale 1 and the second main scale 7 of the digital display diameter ruler. These guide grooves 11 are used to guide the sliding direction of the slider 2, ensuring that the slider 2 can move smoothly and accurately during measurement. The clamping assembly 10 of the slider 2 includes several guide wheels 12, which are rolled within the guide grooves 11. The rolling action reduces friction and makes the sliding of the slider 2 smoother. In addition, the clamping assembly 10 also includes an elastic element 13. One end of the elastic element 13 is fixed to the front scale 8 or the rear scale 9, and the other end is connected to a guide wheel 12. The elastic element 13 (such as a spring) can provide a continuous elastic force, so that the guide wheel 12 always maintains a tight contact with the guide groove 11. This design not only ensures the stability of the slider 2 during sliding, but also avoids hard collisions between the guide wheel 12 and the guide groove 11 through the elastic buffering effect of the elastic element 13, thereby extending the service life and improving the measurement accuracy. In practical use, users can control the contact force between the guide wheel 12 and the guide groove 11 by adjusting the tension of the elastic element 13, thereby further optimizing the sliding performance of the slide ruler 2 and the reliability of the measurement.

[0034] Furthermore, it also includes a set screw 14, which is threaded on the slide 2. After the set screw 14 rotates on the slide 2, it is used to clamp the first main scale 1 or the second main scale 7.

[0035] In this embodiment, the slide 2 of the digital diameter ruler is also provided with a set screw 14, which is threadedly connected to the slide 2. When it is necessary to fix the position of the slide 2, the user can rotate the set screw 14 to move it along the thread towards the first main scale 1 or the second main scale 7 until the end of the set screw 14 is tightly locked onto the surface of the first main scale 1 or the second main scale 7, thereby achieving a stable lock of the slide 2 and ensuring that the slide 2 will not slip during the measurement process, thus improving the accuracy and reliability of the measurement.

[0036] Furthermore, the sliding ruler 2 is also provided with a first inner diameter ruler 15, and the end of the first main ruler 1 is provided with a second inner diameter ruler 16. The distance between the first inner diameter ruler 15 and the second inner diameter ruler 16 is the same as the distance between the first measuring ruler 3 and the second measuring ruler 4. The first inner diameter ruler 15 and the second inner diameter ruler 16 are arranged opposite to each other, and the abutting ends of the first measuring ruler 3 and the second measuring ruler 4 are arranged facing each other.

[0037] In this embodiment, a first inner diameter ruler 15 is provided on the sliding ruler 2, and a second inner diameter ruler 16 is provided at the end of the first main ruler 1. The distance between the first inner diameter ruler 15 and the second inner diameter ruler 16 is the same as the distance between the first measuring ruler 3 and the second measuring ruler 4. The first inner diameter ruler 15 and the second inner diameter ruler 16 are arranged opposite to each other, while the abutting ends of the first measuring ruler 3 and the second measuring ruler 4 are arranged facing each other. Through this structural design, the needs of measuring both the outer diameter and the inner diameter can be met simultaneously, improving the multifunctionality and applicability of the measuring ruler.

[0038] Furthermore, the display component 5 includes a display screen 17 disposed on the front ruler 8, and a sensor 18 disposed on the front ruler 8 for sliding with the front ruler 8, the sensor 18 and the display screen 17 being electrically connected.

[0039] In this embodiment, the display component 5 of the digital diameter ruler includes a display screen 17 mounted on the front ruler 8 and a sensor 18 electrically connected to the display screen 17. The sensor 18 is mounted on the front ruler 8 and can slide along the front ruler 8 on the first main ruler 1 and the second main ruler 7. When the sliding ruler 2 moves, the sensor 18 detects the change in distance between the first measuring ruler 3 and the second measuring ruler 4 in real time and transmits the detected signal to the display screen 17, which then displays the precise measurement value. This design enables real-time display and dynamic updating of measurement data, improving the convenience and accuracy of measurement. At the same time, the electrical connection between the sensor 18 and the display screen 17 ensures the stability and reliability of data transmission.

[0040] Furthermore, the display assembly 5 also includes a power switch 19 and a zeroing switch 20 disposed on the front ruler 8 for electrical connection with the sensor 18 and the display screen 17, and a power supply battery 21 disposed on the front ruler 8 for powering the sensor 18 and the display screen 17.

[0041] In this embodiment, the display assembly 5 also includes a power switch 19 and a zeroing switch 20 disposed on the front ruler 8, as well as a power supply battery 21 for powering the sensor 18 and the display screen 17. The power switch 19 can control the power supply of the entire display assembly 5, allowing users to turn the device on or off as needed; the zeroing switch 20 is used to reset the displayed value to zero before the measurement begins, ensuring the accuracy of the measurement; the power supply battery 21 provides stable power support for the sensor 18 and the display screen 17, ensuring that the device can work normally without an external power source, thus enhancing the portability and practicality of the digital diameter ruler.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
