Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting technology for tower gauges, and specifically discloses an adjustable windproof lighting module for use with tower gauges. Background Technology
[0002] In the field of engineering surveying, accurate elevation measurement and vertical distance determination are core components of construction layout, topographic mapping, and foundation engineering. As an indispensable tool in surveying operations, the leveling rod is a retractable ruler used in conjunction with a level to measure elevation differences. Through clearly marked metric or imperial divisions, it provides surveyors with a precise vertical reference surface.
[0003] Traditional leveling rods are mostly made of lightweight aluminum alloy or wood, with a long, narrow body typically 3, 4, or 5 meters in length. For example, utility model patent CN202153134U discloses a lighting device that can be stably installed on a leveling rod. It includes a pair of clamps with two parallel shafts between them. One end of each shaft is fixedly connected to one opposite side of a different clamp, forming a fixed end. The other end of each shaft passes through one of the clamps, forming a movable end. The clamps can slide offset along the shaft direction, and springs are fitted onto the shafts. A pair of clamping bodies are mounted on the movable ends of the shafts, and LED lights are installed on the outside of the clamping bodies. This device has a simple structure, is easy to manufacture, and allows for convenient height adjustment of the light source, ensuring stable illumination.
[0004] Currently, under sufficient natural light during the day, the reflective coating or contrasting reticle on the surface of the leveling rod can provide adequate visual recognition. However, at night or in low-light environments such as tunnels, mines, and underground engineering projects, without external light sources, the surface of the leveling rod will appear as a blurry shadow due to insufficient light. The contrast between the reticle and the background will drop sharply, making it difficult for surveyors to accurately read the values. At best, they will need to repeatedly adjust their position or wait for a brief change in light. At worst, misreading may cause elevation errors, which will affect the positioning accuracy and safety of the entire project. Conventional supplementary lighting methods rely on manual handheld lighting external equipment to increase brightness, which is not only cumbersome but also affects the observation effect due to lighting angle issues. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide an adjustable windproof lighting module for use with tower gauges, so as to solve the problem of providing supplemental lighting for tower gauges when using them at night or in dimly lit environments.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable windproof lighting module for use with a tower gauge, including a telescopic mechanism, wherein both ends of the telescopic mechanism are provided with clamping mechanisms for tower gauge assembly, and the lower end of the telescopic mechanism is also provided with a power supply mechanism. The telescopic mechanism includes sleeve one, sleeve two and sleeve three that slide together, and end cap one and end cap two for sealing the ends of the sleeves. The clamping mechanism includes a bottom clamp and a top clamp. One side of the bottom clamp is fixed to the lower end surface of the first sleeve by a bracket, and one side of the top clamp is fixed to the upper end surface of the third sleeve by a bracket. The bottom clamp and the top clamp are arranged parallel to each other.
[0007] Furthermore, sleeve 2 is slidably sleeved inside sleeve 1, sleeve 3 is slidably sleeved inside sleeve 2, end cap 1 is fixedly covered at the lower end of sleeve 1, and end cap 2 is fixedly covered at the upper end of sleeve 3.
[0008] Furthermore, a threaded sleeve is fixedly inserted through one side of the first sleeve, and a threaded knob is installed inside the threaded sleeve. The inward end of the threaded knob is tightly abutted against the outer wall of the second sleeve. A threaded sleeve is fixedly inserted through one side of the second sleeve, and a threaded knob is installed inside the threaded sleeve. The inward end of the threaded knob is tightly abutted against the outer wall of the third sleeve.
[0009] Furthermore, each of the three sleeves has a strip-shaped hole on its side, and a transparent plastic plate is slidably fitted inside the strip-shaped hole. An LED light strip is fixedly installed on the inward side of the transparent plastic plate.
[0010] Furthermore, symmetrical limit blocks are fixed inside the strip-shaped hole on both sides. The inner side of the transparent plastic plate is tightly attached to the limit block. The surface of the limit block is provided with a slot. Both ends of the transparent plastic plate are fixedly installed with elastic cards corresponding to the slot positions. The surface of the elastic card and the inside of the slot are interlocked. The shape of the elastic card and the shape of the slot are both regular hexagons.
[0011] Furthermore, both the bottom clamp and the top clamp are U-shaped structures. A threaded sleeve three is embedded and fixed on one side of the inner wall of the bottom clamp. A threaded knob three is installed on the internal thread of the threaded sleeve three. An extrusion plate is fixedly installed on one end of the threaded knob three located inside the bottom clamp. A buffer pad two is bonded and fixed on the inner wall of the bottom clamp away from the threaded sleeve three. A buffer pad one is bonded and fixed on the side of the extrusion plate away from the threaded knob three.
[0012] Furthermore, the power supply mechanism includes a mounting base, a storage battery, and a switch, and the LED light strip is connected to the corresponding terminal on the storage battery via wires.
[0013] Furthermore, a pin sleeve is fixedly installed on the upper end of the mounting base via a bracket. A pin is slidably sleeved inside the pin sleeve. A spring is wound around the surface of the pin. The two ends of the spring are fixedly installed to the end face of the pin sleeve and the end of the pin, respectively. A pin seat is fixedly installed on the upper end of the battery. The end of the pin away from the spring is inserted and connected to the pin seat.
[0014] The working principle and beneficial effects of this solution are as follows: 1. This solution, through the design of a three-section telescopic mechanism, can flexibly adapt to the extension or retraction of the leveling rod. When the leveling rod needs to be adjusted in height during use, the sleeve of the module can be extended or retracted in sequence to ensure that it always maintains a stable fit with the scale area of the leveling rod. This telescopic structure not only occupies little space, but also significantly reduces the overall wind resistance, which helps to reduce wind interference when used outdoors. At the same time, the clamping mechanisms at both ends of the module can firmly fix the leveling rod and prevent displacement due to external factors, thereby improving the stability and reliability of the measurement process. 2. This solution uses LED light strips embedded in the slots of the sleeve and sealed with a transparent plastic plate to ensure that the light directly illuminates the scale area. Users can control the lighting with a switch to achieve accurate readings at night or in dim conditions. In addition, the lighting components are fixed with high-strength transparent materials and elastic clips, which not only ensures durability but also facilitates maintenance and replacement. This effectively overcomes the limitation of traditional leveling rods being difficult to read in low-light environments, significantly improving the efficiency and accuracy of measurement work.

[0018] The following detailed description illustrates the specific implementation method: Example like Figures 1 to 7 As shown, an adjustable windproof lighting module for use with a tower gauge is disclosed, including a telescopic mechanism 1. The telescopic mechanism 1 is used to stretch or retract in conjunction with the use of the tower gauge. Both ends of the telescopic mechanism 1 are provided with clamping mechanisms 2 for tower gauge assembly, and the lower end of the telescopic mechanism 1 is also provided with a power supply mechanism 3. The telescopic mechanism 1 includes sleeve one 10, sleeve two 11 and sleeve three 12 that are slidably sleeved to each other, and end cap one 13 and end cap two 14 for sealing the ends of the sleeves. The clamping mechanism 2 includes a bottom clamp 20 and a top clamp 21. One side of the bottom clamp 20 is fixed to the lower end surface of the first sleeve 10 by a bracket, and one side of the top clamp 21 is fixed to the upper end surface of the third sleeve 12 by a bracket. The bottom clamp 20 and the top clamp 21 are arranged parallel to each other. The bottom clamp 20 and the top clamp 21 are respectively fitted and assembled with the two ends of the leveling rod. By extending and retracting the three sleeves in sequence, the leveling rod can be adjusted in conjunction with the operation.
[0019] Sleeve 10 is internally slidably fitted with sleeve 2 11, and sleeve 2 11 is internally slidably fitted with sleeve 3 12. Sleeve 10, sleeve 2 11, and sleeve 3 12 are all rectangular tube structures with open ends. Through three-section telescopic design, they can be adjusted according to the extension or retraction position of the tower gauge when installed together. The three sleeves adopt a sequential telescopic structure, which makes the overall area occupied small and can effectively reduce wind resistance. When used in combination with the tower gauge, it has a windproof effect. The lower end of sleeve 10 is covered and fixed with end cap 13, which can provide waterproof and dustproof protection for the end of sleeve 10 near the ground. The upper end of sleeve 3 12 is covered and fixed with end cap 2 14, which can provide waterproof and dustproof protection for the upward open end of sleeve 3 12.
[0020] A threaded sleeve 16 is fixed through one side of sleeve 10. A threaded knob 17 is installed on the internal thread of the threaded sleeve 16. The inward end of the threaded knob 17 is tightly fitted against the outer wall of sleeve 2 11. After sleeve 10 and sleeve 2 11 expand and contract relative to each other, the threaded knob 17 can be moved based on the thread of the threaded sleeve 16 to lock and fix sleeve 10 and sleeve 2 11 after expansion and contraction. A threaded sleeve 2 18 is fixed through one side of sleeve 2 11. A threaded knob 2 19 is installed on the internal thread of the threaded sleeve 2 18. The inward end of the threaded knob 2 19 is tightly fitted against the outer wall of sleeve 3 12. After sleeve 2 11 and sleeve 3 12 expand and contract relative to each other, the threaded knob 2 19 can be moved based on the thread of the threaded sleeve 2 18 to lock and fix sleeve 2 11 and sleeve 3 12 after expansion and contraction.
[0021] Sleeve 10, sleeve 2 11, and sleeve 3 12 are all provided with strip-shaped holes 1001 on their sides. The strip-shaped holes 1001 are connected to the interior of the corresponding sleeves. A transparent plastic plate 1002 is slidably fitted inside the strip-shaped holes 1001. The transparent plastic plate 1002 is made of fully transparent high-strength polyvinyl chloride material. After the transparent plastic plate 1002 and the strip-shaped holes 1001 are fitted together, their edges are sealed and reinforced with transparent hot melt adhesive. An LED light strip 1003 is fixedly installed on the inner side of the transparent plastic plate 1002. When the LED light strip 1003 is powered on, it will illuminate the scale area of the leveling rod, so that the leveling rod scale can be accurately determined at night or in low light conditions.
[0022] A limiting block 1004 is symmetrically fixed inside the slot 1001 along both sides. The inward side of the transparent plastic plate 1002 is tightly fitted against the limiting block 1004. The limiting block 1004 restricts the position of the transparent plastic plate 1002 within the slot 1001. A slot 1005 is formed on the surface of the limiting block 1004. Both ends of the transparent plastic plate 1002 are fixedly fitted with elastic clips 1006 corresponding to the positions of the slots 1005. The surface of the elastic clips 1006 and the interior of the slots 1005 are interlocked. The shape of the elastic clips 1006 and the slots 1005... All are hexagonal in shape, and the elastic clip 1006 is made of rubber. When the LED light strip 1003 needs to be embedded in the corresponding sleeve, the LED light strip 1003 is first assembled with the transparent plastic plate 1002, and after the power line of the LED light strip 1003 is led out, the transparent plastic plate 1002 is inserted into the inside of the strip hole 1001. At this time, the limiting block 1004 can limit the embedding depth of the transparent plastic plate 1002. Simultaneously, the elastic clip 1006 is engaged with the inside of the card slot 1005, which can fix the transparent plastic plate 1002 and the strip hole 1001.
[0023] Both the bottom clamp 20 and the top clamp 21 are U-shaped structures. The structural configuration of the bottom clamp 20 is the same as that of the top clamp 21. A threaded sleeve 22 is embedded and fixed on one side of the inner wall of the bottom clamp 20. A threaded knob 23 is installed inside the threaded sleeve 22. A pressing plate 24 is fixedly installed at one end of the threaded knob 23 located inside the bottom clamp 20. When positioning and installing the bottom clamp 20 and the lower end of the leveling rod, the corresponding part of the leveling rod can be placed inside the bottom clamp 20 first. Then, the threaded knob 23 can be moved based on the threaded sleeve 22 to achieve [the desired effect]. The bottom clamp 20 is fixed to the leveling rod. Both the bottom clamp 20 and the top clamp 21 are structurally misaligned with the sleeve part, so that after the leveling rod is connected to the bottom clamp 20 or the top clamp 21, the LED light strip 1003 can stably supplement and brighten the scale surface of the leveling rod. The inner wall of the bottom clamp 20 is bonded and fixed with a buffer pad 26 at the end away from the threaded sleeve 3 22. The side of the extrusion plate 24 away from the threaded knob 3 23 is bonded and fixed with a buffer pad 25. Both buffer pad 25 and buffer pad 26 are rubber pads, which can play a buffering and anti-slip effect when clamping and positioning the leveling rod.
[0024] The power supply mechanism 3 includes a mounting base 30, a storage battery 31, and a switch 32. The LED light strip 1003 is connected to the corresponding terminal on the storage battery 31 via wires. The number of switches 32 corresponds to the number of LED light strips 1003. After the switch 32 is powered on, the LED light strip 1003 can light up by the power supply from the storage battery 31, thus illuminating the scale area of the scale.
[0025] A pin sleeve 301 is fixedly installed on the upper end of the mounting base 30 via a bracket. A pin 302 is slidably sleeved inside the pin sleeve 301. A spring 303 is wound around the surface of the pin 302. The two ends of the spring 303 are fixedly installed to the end face of the pin sleeve 301 and the end position of the pin 302, respectively. A pin seat 304 is fixedly installed on the upper end of the battery 31. The end of the pin 302 away from the spring 303 is inserted and connected to the pin seat 304. When it is necessary to install or remove the battery 31 for charging, the pin 302 is pulled, so that the spring 303 can be stretched. By sliding the pin 302 and the pin seat 304 apart, the pin 302 and the pin seat 304 can be separated, thereby allowing the battery 31 to be slidably detached from the mounting base 30.
[0026] In practice When the measuring rod itself is stretched or retracted for measurement, the operator can adjust the three sleeves accordingly to match the length of the entire module with the current operating length of the measuring rod. This ensures that the top clamp 21 at the top and the bottom clamp 20 at the bottom of the module can be stably attached to the corresponding ends of the measuring rod. This three-section telescopic design, compared to a single robust structure, disperses the overall cross-section, making its projected area on the windward side smaller, thereby effectively reducing the direct effect of wind and achieving a significant windproof effect. This improves the measurement stability of the measuring rod in windy outdoor environments. After the length is adjusted to the correct position, the threaded knob 17 installed on the side of sleeve 10 is rotated to adjust the threaded... Screw sleeve 10 into sleeve 16 until its end is tightly against the outer wall of sleeve 2 11 to lock the relative position of sleeve 10 and sleeve 2 11. Similarly, by rotating the threaded knob 2 19 installed on the side of sleeve 2 11, it is screwed into the threaded sleeve 2 18 and pressed against the outer wall of sleeve 3 12 to lock the relative position of sleeve 2 11 and sleeve 3 12. This double locking mechanism ensures the structural rigidity and fixed reliability of the module under any extension length. In addition, the lower end of sleeve 10 is closed by end cap 1 13 and the upper end of sleeve 3 12 is closed by end cap 2 14. This design effectively prevents rainwater, dust and other foreign objects from entering the interior from the end of the sleeve, protecting the internal components and circuits. Slotted holes 1001 are provided on the sides of sleeve 10, sleeve 2 11, and sleeve 3 12. A transparent plastic plate 1002 is slidably embedded in these holes. The transparent plastic plate 1002 is made of fully transparent high-strength polyvinyl chloride material, which has good light transmittance and mechanical strength. An LED light strip 1003 is fixedly installed on its inner side. To ensure the installation and sealing of the transparent plastic plate 1002, limit blocks 1004 are symmetrically fixed on both sides inside the slotted holes 1001 to limit the embedding depth of the transparent plastic plate 1002. At the same time, the elastic clips 1006 at both ends of the transparent plastic plate 1002 are engaged with the slots 1005 on the surface of the limit blocks 1004 to form a... Mechanical fixing, to further ensure sealing, dustproof and waterproof, the edge joint of the transparent plastic plate 1002 and the strip hole 1001 is also sealed and reinforced with transparent hot melt adhesive. When the LED light strip 1003 is powered on and illuminates, the light passes through the highly transparent plastic plate 1002 and is directly and accurately projected onto the scale surface of the adjacent mounting plate. This built-in lighting design makes the distance between the light source and the scale area close and the direction is correct. It can provide uniform and bright background light or side light for reading in the night or in the dim light measurement environment, which greatly facilitates the measurement personnel to clearly and accurately identify the scale of the mounting plate and avoids the shadows, shaking and reading errors that may be caused by external handheld lighting. The core of the power supply mechanism 3 is the battery 31, which is fixed to the mounting base 30. The connection between the battery 31 and the mounting base 30 adopts a quick-release structure: a pin sleeve 301 is fixed on the mounting base 30, and a pin 302 is installed inside under the action of a spring 303; a pin seat 304 is fixed on the battery 31. During installation, the pin seat 304 is aligned, and the pin 302 will automatically insert into the pin seat 304 to lock under the push of the return force of the spring 303; during disassembly, the pin 302 can be removed for charging or replacement simply by manually overcoming the tension of the spring 303. The operation is extremely convenient. Power is led out from the battery 31 through wires, controlled by the switch 32, and finally delivered to power the LED light strips 1003 in each section. In terms of mechanical fixation, the clamping mechanism 2 consists of a... The clamping mechanism 2 consists of a bottom clamp 20 and a top clamp 21, both of which are U-shaped structures. They are fixed to the lower end of the first sleeve 10 and the upper end of the third sleeve 12 of the telescopic mechanism 1 by brackets, respectively. After the corresponding part of the leveling rod is placed in the U-shaped groove, the threaded knob 23 is rotated to move it forward in the threaded sleeve 22, pushing the front-end extrusion plate 24 towards the leveling rod. The first buffer pad 25 on the extrusion plate 24 and the second buffer pad 26 on the other side of the inner wall of the clamping rod clamp the leveling rod from both sides. The first buffer pad 25 and the second buffer pad 26 are made of rubber material, which provides sufficient friction to prevent slippage and avoids scratches on the surface of the leveling rod that may be caused by direct clamping of metal parts. The installation position of the entire clamping mechanism 2 is designed to be staggered from the strip hole 1001 and the LED light strip 1003 on the sleeve, ensuring that the lighting path is not blocked.
[0027] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics in the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
