Description

Technical Field

[0001] This utility model discloses a self-illuminating barcode ruler, which belongs to the field of engineering measuring instrument technology. Background Technology

[0002] In high-precision elevation control surveying, the elevation difference is typically calculated by accurately reading the readings of two barcode leveling rods using a digital level. However, digital levels require sufficient lighting to read the barcode markings on the leveling rods. While they function normally under good lighting conditions, they struggle to accurately read the markings at night, in tunnels, or in other low-light environments. Therefore, appropriate modifications to the barcode leveling rods to improve their applicability are crucial.

[0003] Currently, when working at night or inside tunnels, illuminating lamps are typically used to illuminate barcode leveling rods. However, this method of illumination from the instrument's position introduces refractive error, reducing observation accuracy. Specifically, because the illuminating lamp illuminates the vertical surface of the rod, the light intensity distribution across the barcode strip is uneven. Since the level instrument needs to simultaneously read the scale markings corresponding to the upper, lower, and middle crosshairs, this uneven illumination can lead to reading errors or reduced accuracy.

[0004] Furthermore, while some modifications have attempted to address this issue, they often introduce excessive auxiliary devices, such as bayonets and sliding rails, which not only increase costs but also add to the complexity of the equipment. At the same time, these auxiliary devices also increase the weight of the leveling rod itself, making station relocation for surveying more cumbersome. Summary of the Invention

[0005] This utility model overcomes the shortcomings of the prior art and proposes a self-illuminating barcode tape, comprising: a transparent tape and an illuminating layer;

[0006] The transparent ruler strip is provided with a scale barcode, and the encoding arrangement of the barcode extends parallel to the axis of the transparent ruler strip;

[0007] The light-emitting layer is disposed on the side of the transparent ruler away from the observation surface and has the same size as the transparent ruler;

[0008] A light source assembly is disposed on the surface of the light-emitting layer near the transparent ruler to provide light to the transparent ruler.

[0009] Preferably, the light source assembly specifically comprises a light-emitting device and a power supply device;

[0010] The light-emitting device is disposed on the surface of the light-emitting layer near the transparent ruler;

[0011] The power supply device is connected with the light-emitting device.

[0012] Preferably, the light-transmitting heat insulation layer is further included.

[0013] The light-transmitting heat insulation layer is arranged between the transparent ruler tape and the light-emitting layer, and is used for isolating the heat generated by the light-emitting layer.

[0014] Preferably, the light-emitting device is specifically a light guide fiber or an LED lamp strip.

[0015] Preferably, the light-emitting device is two.

[0016] The two light-emitting devices are arranged on two sides of the light-emitting layer respectively, and extend from the head end to the tail end of the transparent ruler tape along the extension direction of the coding arrangement of the scale bar code.

[0017] Preferably, the light source assembly is specifically a light-storing material.

[0018] The light-storing material is a long-afterglow fluorescent powder or a light-storing film.

[0019] Preferably, the material of the transparent ruler tape is specifically a glass steel material.

[0020] Preferably, the material of the light-transmitting heat insulation layer is transparent resin or a glass steel material.

[0021] Preferably, the sealing strip is further included.

[0022] The sealing strip is arranged around the self-luminous bar code ruler tape formed by the transparent ruler tape, the light-transmitting heat insulation layer and the light-emitting layer.

[0023] Preferably, the transparent ruler tape, the light-transmitting heat insulation layer and the light-emitting layer are fixedly connected through fasteners.

[0024] Compared with the prior art, the self-luminous bar code ruler tape with the backlight design avoids the problem of unevenness of conventional side light illumination, which leads to uneven light and causes reading failure or precision reduction. At the same time, the backlight design avoids the dependence of the scale on the reflected light to present the scale, thereby eliminating the visual interference caused thereby. Specifically, the reflected light may cause visual blur, glare or ghosting, so that the bar code scale on the ruler becomes unclear, and it is difficult to accurately determine the position or size of each scale, thereby causing the bar code scale to become difficult to clearly read.

[0025] In addition, the light-emitting device of the present application not only has low cost and simple structure, but also is easy to mass produce, thereby further improving the practicality and economy. BRIEF DESCRIPTION OF DRAWINGS

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0032] Please refer to Figure 1 The present embodiment aims to provide a self-luminous bar code ruler tape 1, which comprises: a transparent ruler tape 1.1 and a light-emitting layer 1.3; the transparent ruler tape 1.1 is provided with a scale bar code, and the coding arrangement extension direction of the bar code is parallel to the axis of the transparent ruler tape 1.1; the light-emitting layer 1.3 is arranged on the side of the transparent ruler tape 1.1 away from the observation surface, and is consistent with the size of the transparent ruler tape 1.1; the light-emitting layer 1.3 is provided with a light source assembly on the side surface close to the transparent ruler tape 1.1, so as to provide light source for the transparent ruler tape 1.1.

[0033] Specifically, as Figure 2As shown, in this embodiment, a self-luminous bar code ruler tape 1 is provided, the tape body is made of transparent material to ensure that light can uniformly penetrate and illuminate the scale bar code. The scale bar code is arranged on the transparent tape 1.1, and the coding arrangement extends in parallel with the axis of the transparent tape 1.1, so that the user can clearly read the scale information when observing. The light-emitting layer 1.3 is closely attached to the side of the transparent tape 1.1 away from the observation surface, and the size of the light-emitting layer 1.3 is consistent with that of the transparent tape 1.1. This design ensures that the light-emitting layer 1.3 can uniformly illuminate the entire tape surface, avoiding the problem of uneven lighting. The light-emitting layer 1.3 and the transparent tape 1.1 are combined by suitable adhesive or other fixing means to ensure the stability and durability of the structure. On the side surface of the light-emitting layer 1.3 close to the transparent tape 1.1, a light source assembly is configured to provide a light source. As Figure 1 As shown, the bar code ruler tape 1 body is suspended (fixed) at both ends of the ruler shell by springs to form a ruler with a self-luminous bar code ruler tape 1.

[0034] Further, the light source assembly specifically comprises a light-emitting device and a power supply device; the light-emitting device is arranged on the side surface of the light-emitting layer 1.3 close to the transparent tape 1.1; and the power supply device is connected with the light-emitting device.

[0035] In this embodiment, the light source assembly is preferably a combination of a light-emitting device and a power supply device. The light-emitting device is responsible for generating light, and the power supply device provides power for it. This configuration allows the tape to emit light at any time when needed, improving the convenience of use.

[0036] Specifically, in this embodiment, as Figure 3 As shown, the back of the ruler is not only equipped with two sets of level bubbles 5, but also has lighting devices 4 specially used for illuminating these level bubbles 5. In addition, the power supply device in this embodiment specifically includes two battery compartments 2, which are distributed on both sides of the ruler shell.

[0037] In further embodiments, a brightness adjusting device is also included, which is connected with the light-emitting device and the power supply device for controlling the brightness of the light-emitting device. Specifically, in this embodiment, the brightness adjusting device is a knob-type adjustable light intensity switch 3.

[0038] Further, the light source assembly specifically comprises a light-emitting device and a power supply device; the light-emitting device is arranged on the side surface of the light-emitting layer 1.3 close to the transparent tape 1.1; and the power supply device is connected with the light-emitting device.

[0039] In addition to the combination of the above-mentioned light-emitting device and power supply device, the present embodiment also provides an alternative solution for the light source assembly. That is, using a light-storing material as the light source assembly. The light-storing material can absorb light during the day and emit light in the dark, thus achieving self-luminous without external power supply. This solution is more energy-saving and environmentally friendly, and is suitable for some special application scenarios. In the application of light-storing materials, the present embodiment selects long-persistence fluorescent powder or light-storing film as the preferred material. These materials have good light-emitting effect and longer light-emitting time, which can meet the use requirements in different time periods. By uniformly coating the light-storing material on the light-emitting layer 1.3 or embedding it therein, the self-luminous function of the ruler tape can be realized.

[0040] It should be understood that in further embodiments, the light source assembly of the self-luminous bar code ruler tape 1 is designed more comprehensively and flexibly. Specifically, the light source assembly not only includes the combination of the light-emitting device and the power supply device, but also incorporates light-storing materials. Such a design enables the ruler tape to rely on external power supply to drive the light-emitting device for illumination, ensuring that the scale information can be clearly read. When the power supply device is insufficient, the ruler tape can use the light energy absorbed and stored by the light-storing material to emit light continuously for a period of time in the dark, providing users with a convenient measurement experience.

[0041] Further, the light-transmitting heat-insulating layer 1.2 is also included; the light-transmitting heat-insulating layer 1.2 is arranged between the transparent ruler tape 1.1 and the light-emitting layer 1.3, and is used to isolate the heat generated by the light-emitting layer 1.3.

[0042] As shown in Figure 2 In order to further improve the performance of the ruler tape, the present embodiment also adds a light-transmitting heat-insulating layer 1.2 between the transparent ruler tape 1.1 and the light-emitting layer 1.3. This layer of material has good light-transmitting and heat-insulating properties, can effectively isolate the heat generated by the light-emitting layer 1.3, and protect the transparent ruler tape 1.1 from heat damage to ensure that the scale bar code will not be distorted or blurred, while ensuring that light can pass through smoothly and illuminate the scale bar code.

[0043] Further, the light-emitting device is specifically a light guide fiber or an LED light strip.

[0044] Further, the light-emitting device is two strips;

[0045] The two light-emitting devices are arranged on both sides of the light-emitting layer 1.3, and extend along the coding arrangement direction of the scale bar code from the head end to the tail end of the transparent ruler tape 1.1.

[0046] Specifically, in the selection of light-emitting devices, the present embodiment provides a variety of solutions. One preferred solution is to use optical fiber or LED light strip as the light-emitting device. The present embodiment uses a design in which two light-emitting devices are arranged on both sides of the light-emitting layer 1.3. These two light-emitting devices extend along the direction of the coding arrangement of the scale barcode from the head end to the tail end of the transparent ruler tape 1.1. This layout ensures that light is evenly distributed on the entire surface of the ruler tape, improving the uniformity and clarity of the light.

[0047] Further, the material of the transparent ruler tape 1.1 is specifically glass steel.

[0048] Specifically, the material of the transparent ruler tape 1.1 in the present embodiment is selected as glass steel. This material not only has good transparency, but also has high strength and corrosion resistance, making it suitable for manufacturing ruler tapes that need to withstand certain mechanical stress and environmental challenges.

[0049] Further, the material of the light-transmitting heat-insulating layer 1.2 is transparent resin or glass steel.

[0050] Specifically, in order to effectively isolate the heat generated by the light-emitting layer 1.3 and protect the transparent ruler tape 1.1 from heat damage, transparent resin or glass steel with high strength and heat resistance is selected as the material of the light-transmitting heat-insulating layer 1.2. This layer of material not only prevents heat from being directly transmitted to the transparent ruler tape 1.1, but also ensures that light can pass through smoothly, achieving the effect of illuminating the scale barcode.

[0051] Further, it also includes a sealing strip;

[0052] The sealing strip is arranged around the self-luminous barcode ruler tape 1 composed of the light-transmitting heat-insulating layer 1.2 and the light-emitting layer 1.3 of the transparent ruler tape 1.1.

[0053] Specifically, the sealing strip is specially designed in the present embodiment and is arranged around the self-luminous barcode ruler tape 1 composed of the light-transmitting heat-insulating layer 1.2 and the light-emitting layer 1.3 of the transparent ruler tape 1.1. The main function of the sealing strip is to prevent moisture, dust and other impurities from entering the inside of the ruler tape, thereby prolonging the service life of the ruler tape and maintaining its good light-emitting effect.

[0054] Further, the light-transmitting heat-insulating layer 1.2 and the light-emitting layer 1.3 of the transparent ruler tape 1.1 are fixedly connected through fasteners.

[0055] Specifically, in terms of connection method, fasteners are selected to ensure the firm connection between the light-transmitting heat-insulating layer 1.2 and the light-emitting layer 1.3 of the transparent ruler tape 1.1. This connection method is not only simple and easy to implement, but also very reliable, which can effectively ensure the close adhesion between the layers. In order to prevent light leakage and heat transfer, special attention is paid to the tightness when connecting the layers.

[0056] In the actual operation of the embodiment, screws are used as fasteners to tightly fix the transparent ruler tape 1.1, the light-transmitting and heat-insulating layer 1.2 and the light-emitting layer 1.3 together. In order to ensure the stability of the screw connection and to some extent, disperse the pressure of the screw on the interlayer material, a gasket is inserted into the interlayer screw. This design not only further increases the stability of the connection, but also reduces the damage to the material caused by direct pressure of the screw, thereby prolonging the service life of the ruler tape.

[0057] It should be noted that, in the selection of the material of the light-emitting layer 1.3, in order to avoid the problem of light scattering or leakage, so as to ensure that the display effect is not affected. The surface of the light-emitting layer 1.3 away from the transparent ruler tape 1.1 is designed to be opaque. Based on this requirement, a metal material is selected as the basis of the light-emitting layer 1.3 in the embodiment, and a light-emitting device is embedded in the metal structure.

[0058] However, it should be noted that when the light-emitting device is an optical fiber, the metal material may cause the problems of poor heat conduction and easy damage of the optical fiber. Therefore, in the actual application of the optical fiber as a light-emitting source, a non-metal material such as plastic, glass or ceramic is selected to make the light-emitting layer 1.3. In particular, when glass or plastic is selected as the material of the light-emitting layer 1.3, it is necessary to coat the surface of the light-emitting layer 1.3 away from the transparent ruler tape 1.1 with light-shielding paint to ensure the correct guidance of light and prevent unnecessary leakage. This measure can further improve the display effect and reduce the possibility of glare or observation interference. Specifically, considering that the bar code ruler tape 1 is usually used in outdoor environments, the plastic material is the preferred material for making the light-emitting layer 1.3 due to its lightness, good weather resistance and easy processing. This not only reduces the overall weight of the ruler tape, but also improves its durability and service life.

[0059] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the present application and do not limit the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
