Description
Technical Field
[0001] This utility model relates to the field of engineering measurement technology, specifically to an auxiliary device for front and rear light sources of an indium steel ruler for leveling in low-light environments. Background Technology
[0002] In fields such as civil engineering, rail transit, and mining, leveling is the core means of controlling elevation benchmarks. Precision leveling is usually carried out using an indium steel tape in conjunction with a level. The indium steel tape uses indium steel strip as the base for marking and reading, which has a small coefficient of thermal expansion and high marking accuracy, ensuring measurement precision. When using the indium steel tape, the scale of the indium steel tape needs to be observed through a level to measure the structure of the construction project. However, in dark environments, it is difficult for the level to accurately observe the scale on the indium steel tape, resulting in low measurement efficiency and affecting the accuracy of observation.
[0003] The existing patent authorization announcement number CN222231645U discloses an auxiliary lighting device for an indium steel ruler. The fastening bolt can fasten the bracket to the indium steel ruler, so that the auxiliary lighting device and the indium steel ruler can be fixed into a stable whole. The light strip provides an illumination source for the indium steel ruler, thereby facilitating accurate observation by the measuring personnel in dark environments, thereby improving measurement efficiency and accuracy.
[0004] In the aforementioned patent, the light strip is mounted on a pole, which is fixed to one side of the indium steel ruler. This results in a fixed angle of light irradiation from the light strip onto the indium steel ruler, making it impossible to adjust flexibly according to actual usage. This can lead to reading errors due to the angle of light irradiation, which cannot be adjusted or verified, thus reducing the flexibility of use. Utility Model Content
[0005] The purpose of this invention is to provide an auxiliary device for front and rear light sources of an indium steel ruler for leveling in low-light environments, in order to solve the problem mentioned in the background art that the fixed position of the upright on one side of the indium steel ruler results in a fixed light illumination angle, which cannot be adjusted and verified, thus reducing the flexibility of use.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for front and rear light sources of an indium steel ruler for leveling in low-light environments, comprising an indium steel ruler body, an adjustment component at the top of the indium steel ruler body, a power bank and an illumination strip on the outside of the adjustment component; the adjustment component includes a sleeve that is snapped onto the outside of the top of the indium steel ruler body, a support plate fixedly connected to the rear side of the sleeve, the power bank disposed on the top of the support plate, a connecting shaft fixedly connected to the top of the sleeve, a rotating frame rotatably mounted on the outside of the connecting shaft, a limiting nut threaded onto the top of the connecting shaft and located above the rotating frame, an adjustment port opened on the upper front side of the rotating frame, a sliding rod slidably mounted inside the adjustment port, a reflector fixedly connected to the front side of the sliding rod, the illumination strip disposed on the inner side wall of the reflector and facing the indium steel ruler body, adjustment holes equidistantly opened on the top of the sliding rod, a fixing hole penetrating the adjustment port opened on the top of the rotating frame, and a limiting bolt penetrating the adjustment hole threaded inside the fixing hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. Rotating the sliding rod can drive the rotating frame to rotate around the outer side of the connecting shaft, thereby adjusting the angle of the lighting strip. By sliding the sliding rod along its length within the adjustment port, aligning the multiple equally spaced adjustment holes on the sliding rod with the fixing holes, and screwing in the limit bolts for fixation, the distance between the lighting strip and the indium steel ruler body can be adjusted.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a technical solution: an auxiliary device for front and rear light sources of an indium steel ruler for leveling in low-light environments, including an indium steel ruler body 1, an adjustment component 2 at the top of the indium steel ruler body 1, a power bank 3 and an illumination strip 4 outside the adjustment component 2; the adjustment component 2 includes a retainer 21 that is locked onto the outside of the top of the indium steel ruler body 1, a support plate 22 fixedly connected to the rear side of the retainer 21, the power bank 3 being disposed on the top of the support plate 22, a connecting shaft 23 fixedly connected to the top of the retainer 21, a rotating frame 24 rotatably mounted on the outside of the connecting shaft 23, a limiting nut threaded onto the top of the connecting shaft 23 located above the rotating frame 24, an adjustment port 25 opening above the front side of the rotating frame 24, a sliding rod 26 slidably mounted inside the adjustment port 25, a reflector 27 fixedly connected to the front side of the sliding rod 26, and the illumination strip 4 being disposed on the inner wall of the reflector 27 and facing towards the outside. An indium steel ruler body 1 is provided with a sliding rod 26, the top of which is provided with equal-spaced adjustment holes 28. The top of the rotating frame 24 is provided with a fixing hole 29 that passes through the adjustment port 25. A limiting bolt 210 that penetrates the adjustment hole 28 is installed inside the fixing hole 29. Rotating the sliding rod 26 can drive the rotating frame 24 to rotate around the outside of the connecting shaft 23, thereby adjusting the angle of the lighting strip 4. The sliding rod 26 is slid along its length within the adjustment port 25. By aligning the multiple equal-spaced adjustment holes 28 on the sliding rod 26 with the fixing hole 29, and screwing in the limiting bolt 210 for fixation, the distance between the lighting strip 4 and the indium steel ruler body 1 can be adjusted. The position of the lighting strip 4 can be flexibly adjusted according to actual needs for multiple measurements and comparisons, which significantly improves the flexibility of use and avoids reading errors caused by issues such as the angle of light illumination, providing stable and reliable light source support for leveling work.
[0024] Damping pads 214 are respectively provided on the upper and lower sides of the rotating frame 24 and sleeved on the connecting shaft 23. The damping pads 214 can increase the friction of the rotating frame 24 when it rotates, so that the rotating frame 24 remains stable after the angle is adjusted and will not be affected by slight external touch or its own weight. This further ensures the accuracy of the illumination position of the lighting strip 4 and provides a more reliable guarantee for the leveling measurement reading.
[0025] Mounting holes 211 are provided on both the left and right sides of the ferrule 21. The internal threads of the mounting holes 211 are used to install fixing bolts 212 located inside the indium steel ruler body 1. By connecting the fixing bolts 212 to the indium steel ruler body 1, the ferrule 21 can be firmly fixed to the indium steel ruler body 1, thereby ensuring the reliability of the connection between the entire lighting auxiliary structure and the indium steel ruler body 1. This avoids the position of the lighting strip 4 from changing due to loose connection during the measurement process, further ensuring the stability and accuracy of the leveling work. The mounting holes 211 provide precise positioning for the installation of the fixing bolts 212, making the installation process more convenient and efficient, reducing the installation difficulty, and improving the assembly efficiency of the device.
[0026] Both the limit bolt 210 and the fixing bolt 212 are equipped with hand-tightening round caps at their ends. The surface of the hand-tightening round caps is provided with anti-slip texture, allowing operators to directly tighten them by hand without the need for additional tools. This greatly simplifies the installation, disassembly, and angle adjustment process of the device, and improves the convenience and efficiency of operation.
[0027] The reflector 27 has an arc-shaped cross-section and is aligned with the length of the indium steel ruler body 1. This allows for efficient focusing and reflection of the light emitted from the illumination strip 4, concentrating the light onto the scale area of the indium steel ruler body 1. This effectively enhances the illumination intensity of the scale area and reduces light scattering loss. At the same time, the arc-shaped structure design ensures that the coverage of the reflected light matches the scale distribution of the indium steel ruler body 1, guaranteeing uniform and sufficient illumination from the top to the bottom scale of the indium steel ruler body 1. This avoids situations where the local illumination is too dim or too bright, further improving the clarity and accuracy of readings during leveling measurements in low-light environments.
[0028] Please see Figure 1 and Figure 5The top of the sliding rod 26 is provided with a wiring groove 213. The upper end of the lighting strip 4 is fixedly connected to a wire 41 located in the wiring groove 213. The power bank 3 is fixedly connected to the outside of the power cord 3. The end of the wire 41 is provided with a plug connector 42 adapted to the power cord 31. The plug connector 42 is movably connected to the power cord 31. The lighting strip 4 is quickly connected to the power cord 31 by means of the wire 41 and the plug connector 42. When the lighting strip 4 is damaged, the plug connector 42 can be operated to quickly separate the wire 41 from the power cord 31 and remove the lighting strip 4 from the reflector 27. Subsequently, a new lighting strip 4 is replaced. After wiring along the cable tray 213, the wire 41 is connected to the power cord 31 again using the connector 42, facilitating the replacement of the lighting strip 4. A switch is installed on the power bank 3; by connecting it to the lighting strip 4, turning on the switch powers the lighting strip 4. This switch allows users to flexibly control the lighting strip 4's on / off state according to the actual measurement environment, eliminating the need for frequent plugging and unplugging of the connector 42 and reducing operational steps. In well-lit environments, turning off the switch cuts off the power to the lighting strip 4, avoiding unnecessary power consumption and extending the power bank 3's battery life. In low-light or dark environments, turning on the switch quickly activates the lighting strip 4, providing illumination to the scale area of the indium steel ruler 1, ensuring the continuity and efficiency of the measurement work. Furthermore, the switch is located on the outside of the power bank 3, making it easily accessible when holding or placing the device, further enhancing operational convenience.
[0029] The lighting strip 4 is adhesively attached to the inner wall of the reflector 27. Adhesive is provided on the back of the lighting strip 4, which can quickly fix the lighting strip 4 to the reflector 27. Moreover, when the lighting strip 4 needs to be replaced, it can be peeled off from the reflector 27 by applying appropriate external force without damaging the inner wall of the reflector 27, thus ensuring the integrity of the reflector 27 and its normal use thereafter. The adhesive connection also allows the lighting strip 4 to fit tightly against the inner wall of the reflector 27, reducing the gap between the two and ensuring that the light emitted by the lighting strip 4 can be reflected by the reflector 27 to the surface of the indium steel ruler to the maximum extent, thereby improving the lighting effect and providing a stable and sufficient light source for leveling in low-light environments.
[0030] Working principle: The sleeve 21 is attached to the top of the indium steel ruler body 1, and the fixing bolts 212 on the left and right sides are screwed into the indium steel ruler body 1 through the mounting hole 211 for fixing. The power bank 3 supplies power to the lighting strip 4. The switch on the power bank 3 is operated to turn on the lighting strip 4 to illuminate one side of the scale of the indium steel ruler body 1.
[0031] Rotating the sliding rod 26 can drive the rotating frame 24 to rotate around the outside of the connecting shaft 23. The damping pad 214 set outside the connecting shaft 23 provides damping as the rotating frame 24 rotates, which can ensure the stability of the angle after rotation adjustment. The angle of the lighting strip 4 can be adjusted. At the same time, by unscrewing the limit bolt 210 and sliding the sliding rod 26 in the adjustment port 25 along the length of the sliding rod 26, the multiple adjustment holes 28 and fixing holes 29 set at equal intervals on the sliding rod 26 are overlapped and the limit bolt 210 is screwed in to fix it. Thus, the distance between the lighting strip 4 on the reflector 27 at the front end of the sliding rod 26 and the indium steel ruler body 1 can be adjusted. In addition, the position of the lighting strip 4 can be flexibly adjusted according to the actual use, which improves the flexibility of use.
[0032] The lighting strip 4 is attached to the reflector 27 and quickly connected to the wire 41 and power cord 31 via the connector 42. When the lighting strip 4 is damaged, the wire 41 and power cord 31 can be quickly separated by operating the connector 42, and the lighting strip 4 can be peeled off the reflector 27. A new lighting strip 4 is then attached and routed along the wiring groove 213. The wire 41 and power cord 31 are then connected again using the connector 42, thus facilitating the replacement of the lighting strip 4. The above describes the working process of the entire device. Any content not described in detail in this specification belongs to the prior art known to those skilled in the art.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
