Description

Technical Field

[0001] This invention relates to the field of support structure technology for high-precision measuring instruments, and particularly to an adjustable indium steel ruler support leg and its working method. Background Technology

[0002] Precision leveling, as a core technology for transferring elevation benchmarks, directly impacts the quality control level of projects such as deformation monitoring of major infrastructure and installation and positioning of precision equipment. In typical application scenarios such as high-speed rail track smoothness testing, dam settlement observation, and precision machine tool leveling, the measurement system must possess sub-millimeter stability to ensure the reliability of the collected data. The indium steel ruler, as a key benchmark carrier in this measurement system, has a decisive influence on measurement accuracy due to the stability of its support structure. Specifically, any minute deformation or displacement of the support device will be significantly amplified through the leverage effect, thus affecting the accuracy of the measurement results. Therefore, the fine-tuning accuracy, resistance to environmental interference, and terrain adaptability of the support device become key factors restricting measurement accuracy.

[0003] Traditional indium steel ruler support frames generally use wooden strut structures; however, numerous technical defects have been exposed during long-term use. From a material properties perspective, wood's hygroscopic expansion and contraction during drying cause the levelness of the support surface to easily become inaccurate with fluctuations in ambient temperature and humidity. Furthermore, wood is prone to structural deterioration such as insect infestation, decay, and joint cracking during long-term use, further affecting the stability and durability of the support structure. From a mechanical performance perspective, fixed-length struts and rigid connections are difficult to adapt to complex terrains such as slopes and steps, and external disturbances can easily lead to gradual settlement and displacement, affecting measurement accuracy.

[0004] In terms of operational reliability, traditional support scaffolds rely on purely manual adjustment, which not only limits adjustment precision but also lacks anti-slip protection mechanisms, posing a risk of instrument tipping. Furthermore, loosening of connectors due to wood aging further reduces the stability of the support's rigidity. More critically, traditional wooden struts lack a precise adjustment mechanism; height and angle adjustments are entirely manual, demanding extremely high levels of expertise from operators and failing to meet the precision requirements of modern high-precision leveling. Specific problems are as follows: 1. Material deformation problem: Wooden support rods are significantly affected by ambient temperature and humidity, and are prone to moisture absorption expansion and drying shrinkage, which leads to inaccurate levelness of the support surface and affects measurement accuracy; 2. Insufficient adjustment precision: Traditional support legs lack precision adjustment mechanisms, and height and angle adjustments rely on manual operation, making it difficult to guarantee adjustment precision and failing to meet the needs of high-precision measurement; 3. Poor terrain adaptability: Fixed-length struts and rigid connection methods are difficult to adapt to complex terrains, such as slopes and steps. They are prone to settlement and displacement under external disturbances, affecting measurement stability. 4. Unreliable locking: Traditional support legs lack an effective locking mechanism, and are prone to accidental displacement under external force, leading to inaccurate measurement reference. 5. Insufficient ease of operation: The purely manual adjustment mode is cumbersome to operate, requires a high level of professional skills from the staff, and lacks an anti-slip protection mechanism, posing a safety hazard.

[0005] Currently, although some improved indium steel ruler support devices have appeared on the market, they still have many shortcomings. Taking the "High-precision indium steel ruler with sliding telescopic legs" disclosed in CN106289171A as an example, although the invention improves the stability and accuracy of measurement to some extent by setting telescopic legs on the back of the indium steel ruler body, the adaptability of its telescopic leg design in complex terrain still needs to be improved. Especially on extremely uneven ground, its adjustment range and stability may not meet the needs of high-precision measurement. In addition, the structure of this design is relatively simple, and its effect on fatigue relief during long-term measurement operations is limited.

[0006] Similarly, while the "Adjustable Indium Steel Ruler Support" disclosed in CN213688342U can reduce measurement errors to some extent through the use of a unique support and ruler clamp, its overall structure remains complex. Furthermore, its adjustment mechanism primarily relies on the coordination of rotating and telescopic legs, resulting in insufficient real-time response to terrain changes. In complex and variable measurement environments, this support may not be able to quickly adjust to the optimal measurement state, thus affecting measurement efficiency and accuracy.

[0007] In summary, traditional indium tinplate ruler support tripods and existing improved devices have significant shortcomings in terms of material deformation, adjustment accuracy, terrain adaptability, locking reliability, and ease of operation, making it difficult to meet the demands of modern high-precision leveling. The combined deficiencies of these existing technologies make it difficult for traditional support devices to simultaneously achieve the required efficiency, reliability, and intelligence in engineering surveying. Therefore, developing a new type of indium tinplate ruler support tripod device with self-adaptive structure, precise operation, and integrated functions is an urgent and crucial need for improving the accuracy of precision leveling. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to provide an adjustable indium steel ruler support tripod and its working method, which solves the problems of poor terrain adaptability, complicated adjustment, single function and insufficient stability of existing tripods. It realizes flexible adjustment of height and level, adapts to different ground fixing requirements, integrates lighting and accessory protection functions, and has shock absorption and buffering performance, meeting the use requirements of high-precision measurement scenarios. Moreover, it is easy to operate by a single person and requires no professional training.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: The core of this invention, an adjustable indium steel ruler support bracket, lies in the ingenious layout and precise construction of its support components. These components consist of several circumferentially distributed adjustable support legs, each comprising a fixed leg and a movable leg. The fixed leg is made of high-strength stainless steel, and its inner wall is specially designed with four longitudinal guide grooves and an array of variable-pitch adjustment holes, providing reliable assurance for the stable sliding and precise positioning of the movable leg. The movable leg achieves quick locking with the fixed leg via a spring-loaded positioning pin assembly. This assembly cleverly utilizes the elastic potential energy of the spring, allowing the positioning pin to freely switch between adjustment holes, achieving both coarse height adjustment and fine-tuning, ensuring flexibility and accuracy during the adjustment process. The support legs are connected to the main body of the device via rotary bearings. The bearing assembly incorporates an axial positioning structure and a radial limiting structure, enabling multi-angle adjustment of the support legs and ensuring stability and safety during adjustment. Simultaneously, the introduction of a ratchet self-locking mechanism further enhances the locking reliability of the support legs at any angle, effectively preventing accidental loosening due to external forces.

[0010] To adapt to complex and varied terrain, this invention also features replaceable adapter components at the ends of the support legs. Through conversion connectors, the foot spike assembly and suction cup assembly can be easily switched, ensuring the most suitable support method for soft soil, hard rock, or smooth surfaces, thus significantly improving the terrain adaptability of the support tripod. Furthermore, a rectangular groove on one side of the device body is lined with an elastic buffer layer. This design effectively isolates the impact of external vibrations on the measurement reference, reduces mechanical vibration interference, and ensures the stability and accuracy of observation data acquisition. The quick-release LED searchlight assembly integrated into the device body provides ample lighting support for nighttime operations, further expanding the application scenarios of the support tripod.

[0011] The working method of this invention also demonstrates its technical superiority and practicality. In use, firstly, a suitable adapter component is selected based on the measurement environment and installed at the end of the support leg. Then, the height of the movable leg is adjusted to allow the support frame to initially adapt to the terrain. Next, the angle of the support leg is finely adjusted using a rotary bearing and ratchet self-locking mechanism until the optimal support state is achieved. During the adjustment process, the synergistic effect of the spring positioning pin assembly and the variable-pitch adjustment hole array ensures accurate and convenient adjustment. Finally, the quick-release LED searchlight assembly is turned on for nighttime operation illumination or used as an auxiliary positioning tool to improve measurement efficiency. Throughout the entire operation, the various components of the support frame work together to provide a stable and reliable support platform for the invar steel ruler, effectively ensuring the smooth execution of high-precision measurements.

[0012] The adjustable indium steel ruler support bracket and its working method provided by this invention have the following beneficial effects: 1. This invention employs a multi-angle load-bearing structure design, which consists of several interconnected and evenly distributed support rods. The support stiffness is more than three times higher than that of traditional wooden support rods, and it can maintain excellent stability in various measurement environments, laying a solid foundation for high-precision measurement and effectively avoiding the problem of measurement data fluctuation caused by unstable support.

[0013] 2. This invention utilizes a clever configuration of rotatable legs and dual-mode contact components. The rotatable legs can rotate freely within a 360-degree range, and the dual-mode contact components can switch between hard contact and soft adsorption modes depending on the ground material. This significantly reduces the settlement offset of the device on a 15-degree slope from eight millimeters in the traditional structure to no more than 0.5 millimeters, demonstrating excellent terrain adaptability and maintaining a stable measurement state in complex terrain.

[0014] 3. This invention replaces traditional wooden support rods with steel support legs. The steel support legs are made of high-strength alloy steel and undergo a special heat treatment process to enhance their strength and toughness. This effectively resists the influence of external force deformation and changes in environmental temperature and humidity on the material properties, significantly improving the long-term durability and stability of the support system, extending the service life of the device, and reducing the cost of use.

[0015] 4. This invention completely overcomes the problem of inaccurate horizontality of the support surface caused by the expansion of the traditional wooden support rod due to moisture absorption. By setting an adjustable compensation mechanism between the support surface and the support rod, the compensation mechanism can automatically adjust the horizontality of the support surface when the support rod deforms due to moisture absorption and expansion, ensuring the long-term stability and accuracy of the measurement benchmark and improving the reliability of the measurement.

[0016] 5. The ratchet mechanism designed in this invention provides multi-angle positioning and mechanical self-locking functions. The ratchet mechanism adopts high-precision gear transmission, which has the characteristics of accurate positioning and reliable self-locking. It effectively avoids accidental displacement caused by external forces during the observation process, ensures adjustment accuracy and locking stability, and allows the measurement personnel to focus more on the measurement work and improve measurement efficiency.

[0017] 6. This invention utilizes a ratchet mechanism and an unlock button linkage design. The unlock button is positioned in an easily accessible location. When the unlock button is pressed, the self-locking state of the ratchet mechanism is released, enabling quick unlocking and automatic locking of the fixed leg. No additional tools are required, greatly facilitating operation and use, and reducing operation time and labor intensity.

[0018] 7. This invention enables a single person to easily adjust the height and level. By optimizing the structural design and operation process of the device, the height adjustment and level adjustment are integrated on one operation panel, and the level error is strictly controlled within 0.05mm / m, which fully ensures the measurement accuracy and reliability and improves the flexibility and convenience of measurement.

[0019] 8. The operation time of this invention is no more than five minutes. By simplifying the operation steps and optimizing the mechanical structure of the device, unnecessary operation links and time waste are reduced, significantly improving measurement efficiency, reducing manual operation time and costs, and providing strong support for fast and efficient measurement operations. It is especially suitable for measurement tasks with high time requirements.

[0020] 9. This invention utilizes the synergistic design of an elastic buffer layer and a guide groove. The elastic buffer layer is made of highly elastic rubber material, and the guide groove has a precise guiding function, which can effectively isolate the transmission of external vibrations, reduce mechanical vibration interference during the measurement process, ensure the stability and accuracy of the observation data, and improve the quality and reliability of the measurement data.

[0021] 10. This invention utilizes the shock absorber design of the movable leg's buffer spring, buffer pad, and suction cup assembly. The buffer spring is made of a high-strength, high-elasticity alloy spring, the buffer pad is made of a soft material with good shock absorption performance, and the suction cup assembly can adhere tightly to the ground, effectively absorbing external vibrations, further ensuring the stability of the measurement process, improving the overall measurement accuracy, and making the measurement results more accurate and reliable.

[0022] 11. This invention integrates a quick-release LED searchlight assembly. The LED searchlight assembly uses a high-brightness, low-energy-consumption LED light source. Through its quick-release design, it can be quickly installed and disassembled, providing lighting support for nighttime operations, expanding the time range of measurement operations, improving operational flexibility and efficiency, and facilitating measurement work for surveyors at night or in environments with insufficient light.

[0023] 12. The present invention adopts a modular structure design, which allows internal components to be replaced independently. The modules are connected through standard interfaces. When a component fails, only the corresponding module needs to be replaced, which greatly reduces the complexity and cost of equipment maintenance, provides convenience for long-term use and maintenance of equipment, and improves the maintainability and upgradeability of equipment.

[0024] 13. This invention extends the lifespan of LED searchlights through a heat dissipation base design. The heat dissipation base is made of high thermal conductivity material and has a reasonable heat dissipation channel, which can dissipate the heat generated by the LED searchlights in a timely manner. At the same time, each component is detachable for easy daily inspection, maintenance and replacement, further extending the overall lifespan of the equipment and reducing the operating cost of the equipment.

[0025] 14. The modular interface system of this invention supports the rapid replacement of equipment such as total stations and GPS receivers through adapters. The modular interface system has a unified interface standard and compatibility design. The adapters can quickly and accurately connect different devices, realize functional expansion and extension, improve the practicality and adaptability of equipment in different measurement scenarios, and meet diverse measurement needs.

[0026] 15. This invention utilizes the telescopic adjustment and wide-range angle adjustment capabilities of the support legs, as well as the detachable and switchable design of the foot spike assembly and suction cup assembly. The telescopic adjustment of the support legs adopts a high-precision screw transmission mechanism, and the angle adjustment range can reach 0~90 degrees. The foot spike assembly is suitable for soft ground, while the suction cup assembly is suitable for hard and smooth ground, making the device adaptable to various ground surfaces such as soft, hard, and uneven surfaces, breaking through the terrain limitations of traditional measuring devices and expanding the applicability of the device.

[0027] 16. This invention not only significantly improves the overall performance and adjustment accuracy of the support system, but also greatly enhances terrain adaptability. By comprehensively utilizing the above-mentioned multiple technical features, it effectively meets the requirements of engineering surveying for high efficiency, reliability and intelligence. It has broad application prospects and promotion value, and can bring significant economic and social benefits to the field of engineering surveying. Attached Figure Description

Detailed Implementation

[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1 like Figures 1 to 14 As shown in the figure, this embodiment provides an adjustable indium steel ruler support bracket, the specific structure of which is as follows: 1. Main body of the device like Figures 2 to 4 ,and Figure 10As shown, a groove is opened on the front side of the main body 1 of the device, and several elastic buffer layers 2 are installed in the groove to protect the indium steel ruler 12 and accessories from collision damage; a set of independently sliding baffles 8 are set at the opening end of the groove, and spring positioning pins 801 are set on the upper and lower edges of the baffles 8. A pull-out operating handle 802 is installed on the outside, and a fan-shaped block is set at the end of the operating handle 802. The indium steel ruler 12 is fixed and stably limited by sliding the baffles 8.

[0030] A groove 102 is provided on the rear side, and an LED searchlight assembly 6 is installed inside the groove 102; a shield 103 is provided on the rear side and the left and right sides respectively to protect the internal ratchet mechanism 7 and prevent dust and impurities from entering and affecting the operation of the mechanism.

[0031] Several unlocking buttons 101 are installed on the top. The unlocking buttons 101 are linked to the ratchet mechanism 7. Pressing the unlocking button 101 can release the ratchet mechanism 7 from its locked state, allowing the fixed leg 3 to be freely adjusted. After releasing, it automatically resets and locks.

[0032] 2. Spring locating pin 801 like Figure 11 As shown, the spring positioning pin 801 includes a housing 8011, a fixed spring 8012 inside the housing 8011, and a fixed bead 8013 above the spring 8012. The bead 8013 is a solid part consisting of a lower cylinder and an upper hemisphere. The spring 8012 pushes the bead 8013 to contact the inner wall of the groove, thereby enhancing the positioning stability of the baffle 8 after sliding and preventing the baffle 8 from shifting during the measurement process.

[0033] 3. Fixed leg 3 and movable leg 9 like Figure 5 As shown, the fixed leg 3 includes an axial positioning structure 301, which is connected to the ratchet mechanism 7. The guide groove 302 is connected to the axial positioning structure 301 through a threaded interface 303. An adjustment hole 304 is provided on the guide groove 302. The height of the fixed leg 3 can be coarsely adjusted through the adjustment hole 304 to adapt to different terrain height requirements.

[0034] like Figure 12 and Figure 13 As shown, the upper part of the movable leg 9 is provided with a guide block 904, and the guide block 904 is evenly distributed with sliding balls 901 around its radial circumference to reduce the frictional resistance when the movable leg 9 extends and retracts, making the adjustment smoother. The lower end of the guide block 904 is connected to the base 902, and the base 902 is radially slidably equipped with a pin head 906. The pin head 906 is connected to a buffer pad 905. The buffer pad 905 is installed inside the base 902 and is connected to a buffer spring 903. The other end of the buffer spring 903 is fixed to the inner wall of the base 902. Through the elastic action of the buffer spring 903 and the buffer pad 905, the buffering function of the movable leg 9 is realized, adapting to uneven ground and reducing the transmission of external vibrations.

[0035] like Figure 1 and Figure 2 As shown, the movable leg 9 is equipped with a foot pedal 4 on its side, which makes it easy for the operator to step on it and apply force, and to assist in adjusting the height and fixing of the tripod; the lower end can be detachably installed with a suction cup assembly 11 and / or a foot spike assembly 5 through a conversion connector 10, so as to realize the switching of positioning support for different ground surfaces.

[0036] 4. Foot spike assembly 5 and suction cup assembly 11 like Figure 6 As shown, the foot spike assembly 5 includes a connecting base 501. The upper part of the connecting base 501 is connected to the movable leg 9 via a conversion connector 10, and the lower part is connected to the spike body 503 via an adjusting nut 502. Rotating the adjusting nut 502 can control the extension and retraction of the spike body 503. On soft ground, the spike body 503 extends out and inserts into the ground to enhance support stability.

[0037] like Figure 14 As shown, the suction cup assembly 11 includes a steering bearing 1101. The upper part of the steering bearing 1101 is connected to the movable leg 9 through a conversion joint 10, and the lower part is connected to the wheel frame body 1102. The wheel frame body 1102 is connected to the shock absorber 1104 through a pulley shaft 1103. The lower part of the shock absorber 1104 is equipped with a suction cup 1105. When on a smooth and hard surface, the suction cup 1105 is used to adhere to the ground, while the shock absorber 1104 reduces the impact of vibration and ensures stable support.

[0038] 5. LED searchlight assembly 6 like Figure 7 As shown, the LED searchlight assembly 6 includes a clip 602, which is snapped into the slot 102 to enable quick installation and removal of the LED searchlight assembly 6. The clip 602 is connected to the heat dissipation base 601, on which the LED searchlight 603 is mounted. The heat dissipation base 601 is made of a high thermal conductivity material, which can quickly dissipate the heat generated by the LED searchlight 603 during operation and extend its service life. The LED searchlight 603 provides sufficient illumination for measurement in dim environments, and the illumination angle can be finely adjusted by the steering bearing 1101.

[0039] 6. Ratchet mechanism 7 like Figure 8 and Figure 9 As shown, the ratchet mechanism 7 includes a central rotating shaft 707, which is rotatably mounted inside the main body 1 of the device. An axial positioning structure 301 is installed in the middle, and ratchet gears 706 are installed at both ends. A set of reset devices 703 is installed above, and the reset devices 703 are connected to the linkage rod 701. A radial limiting structure 702 is installed in the middle of the linkage rod 701 to limit the radial displacement of the linkage rod 701 and ensure the stable operation of the mechanism.

[0040] The linkage rod 701 is designed as a T-shaped structure, hollow inside and open at three ends, with a support rod 705 installed inside. The support rod 705 is a triangular support structure, with the two lower supports being bent structures. The three ends of the support rod 705 are respectively equipped with a return spring 704, and the other ends of the three return springs 704 are respectively connected to the unlock button 101 and a set of reset devices 703. The unlock button 101 is installed at the vertical end of the T-shaped linkage rod 701.

[0041] Press the unlock button 101 to push the middle support downward, causing the lower part of the support rod 705 to straighten and extend, squeezing the return spring 704 outward, driving the reset device 703 to disengage from the ratchet 706, and releasing the lock; release the unlock button 101, the return spring 704 resets, pulls the reset device 703 to engage with the ratchet 706, realizes automatic locking, and ensures the stability of the fixed leg 3 after adjustment.

[0042] Example 2 In another preferred embodiment, based on the above embodiment 1, this embodiment provides an adjustable indium steel ruler support bracket, which is ingeniously designed and fully functional. It mainly includes a device body 1 and a triangular load-bearing support component at the bottom, which is composed of three adjustable support legs evenly distributed around the circumference.

[0043] 1. Support leg connection and adjustment: like Figure 1 , Figure 2 , Figure 5 and Figure 8 As shown, the upper ends of each support leg are rotatably connected to the central rotating shaft inside the main body 1 of the device via high-precision bearing assemblies. The bearing assembly contains an axial positioning structure 301 to ensure stable positioning of the support leg in the axial direction and prevent offset; at the same time, it is provided with a radial limiting structure 702 to effectively limit the radial sway of the support leg, allowing it to rotate circumferentially around the central rotating shaft, thus realizing flexible adjustment of the angle.

[0044] 2. Support leg structure and material: The support leg adopts a double-layer sleeve structure, consisting of an outer fixed leg 3 and an inner sleeved movable leg 9. Both are made of corrosion-resistant and high-strength 304 stainless steel to ensure stability and durability under long-term use.

[0045] like Figure 5 As shown, four longitudinal guide grooves 302 are specially provided on the inner wall of the fixed leg 3, and a sliding ball 901 is installed at the corresponding position on the outer wall of the movable leg 9. The sliding ball 901 is embedded in the guide groove 302, which not only restricts the circumferential rotation of the movable leg 9, but also ensures its smooth sliding along the axial direction.

[0046] The fixed leg 3 is provided with variable spacing adjustment holes 304 along the axial direction, wherein the hole spacing in the end area is designed to be smaller than that in the upper area, so as to meet the fine locking requirements under different height adjustment needs.

[0047] 3. Adjustment and locking of movable leg 9: like Figure 12 and Figure 13 As shown, a spring positioning pin assembly is horizontally arranged on the upper part of the movable leg 9. This assembly includes precision components such as a retractable pin head 905, a sliding ball 901, a base 902, and a buffer spring 903.

[0048] When adjusting the height, simply press the pin 905 gently to compress the buffer spring 903, causing the pin 905 to disengage from the current adjustment hole. Then slide the movable leg 9 to the target hole position to release the pin 905. Under the action of the buffer spring 903, the pin 905 will automatically insert into the adjustment hole 304 to achieve a secure lock.

[0049] 4. End connection and fixing method: like Figure 1 As shown in the figure, the end of the movable leg 9 is provided with an external threaded interface, which can be easily disassembled and connected to the adapter 10. The adapter 10 is designed with multiple interface types to adapt to the installation of the foot spike assembly 5 and the suction cup assembly 11, so as to meet the fixing requirements of different ground surfaces.

[0050] like Figure 6 As shown, the spike body 503 of the foot spike assembly 5 is designed with a sharp point, making it easy to insert into soft ground. The extension length of the spike body 503 can be adjusted by rotating the adjusting nut 502, thereby enhancing the grip and ensuring the stability of the device.

[0051] The suction cup assembly 11 is flexibly connected to the adapter 10 via a steering bearing mechanism, and can be adsorbed and fixed on a smooth, hard surface, providing stable support.

[0052] 5. Auxiliary operation design: like Figure 1 and Figure 2 As shown, the side of the end of the movable leg 9 is provided with an extended foot pedal 4 with anti-slip texture, which makes it easy to push the movable leg to extend and retract by applying force with the foot, thus improving the ease of operation.

[0053] 6. The main body 1 of the device is fixed to the indium steel ruler 12: like Figure 1 , Figure 2 and Figure 10 As shown, a rectangular groove is opened on one side of the main body 1 of the device, and the inner side of the groove wall is covered with an elastic buffer layer 2 made of foam sponge material, which effectively protects the indium steel ruler from collision damage.

[0054] The groove contains two independently sliding baffles 8, with guide sliders 801 at the upper and lower edges of the baffles, which are embedded in the grooves to achieve smooth sliding. The outer side is controlled by a pull-out operating handle 802, which facilitates quick adjustment of the baffle position.

[0055] When locking the indium steel ruler, place the ruler body into the main body 1 of the device, push the baffle 8 to clamp the ruler body, and then lift the operating handle 802. The sector block is inserted into the groove of the main body 1 of the device to achieve mechanical locking and ensure the stability of the indium steel ruler during the measurement process.

[0056] Example 3 In another preferred embodiment, based on the above embodiments 1 and 2, this embodiment provides an adjustable indium steel ruler support bracket, which is composed of core components such as the main body 1, fixed leg 3, movable leg 9, suction cup assembly 11, foot nail assembly 5, ratchet mechanism 7, and LED searchlight assembly 6, forming a triangular support structure that can adapt to complex terrain and has high-precision positioning capability.

[0057] 1. Main framework The main body 1 of the device is made of high-strength aluminum alloy casting. A groove is opened on the front side to place the indium steel ruler 12. An elastic buffer layer 2 (made of silicone) is embedded in the groove. A set of independently sliding baffles 8 is installed at the open end. The baffles 8 achieve multi-level positioning through spring positioning pins 801. The fan-shaped block design at the end of the operating handle 802 facilitates one-handed pull adjustment. A slot 102 is set on the rear side to hold the LED searchlight assembly 6. The left, right and rear sides are covered with shielding plates 103 to protect the ratchet mechanism 7.

[0058] 2. Adjustment and control module Three unlocking buttons 101 are installed on the top and connected to the ratchet mechanism 7 via a T-shaped linkage rod 701. When a button is pressed, the triangular support structure of the support rod 705 pushes the return spring 704, releasing the ratchet 706 from its locked state, thus achieving 360° stepless adjustment of the fixed leg 3.

[0059] 3. Adjustable support system (1) Fixed leg Each fixed leg 3 is connected to the central rotating shaft 707 of the ratchet mechanism 7 via an axial positioning structure 301, and the guide groove 302 is axially fixed using a threaded interface 303. Ten equidistant adjustment holes 304 are provided on the surface of the guide groove 302, which, together with the guide block 904 of the movable leg 9, enable a combination of coarse and fine height adjustment.

[0060] (2) Moving legs The upper guide block 904 of the movable leg 9 has six radially arranged sliding balls 901, which form a low-friction sliding pair with the guide groove 302. The lower base 902 has a built-in buffer spring 903, which pushes the buffer pad 905 through the pin head 906 to achieve three-level buffering (stiffness coefficients of 50N / mm, 100N / mm, and 200N / mm respectively), adapting to ground undulations of 0~50mm.

[0061] (3 ground adaptation components) Foot spike assembly 5: The connecting base 501 is connected to the movable leg 9 through the adapter 10. The spike body 503 adopts a hollow structure. The extension range of 0-80mm is controlled by the adjusting nut 502. The end cone angle is designed to be 45° to improve the penetration force.

[0062] Suction cup assembly 11: Steering bearing 1101 achieves ±15° angle compensation, shock absorber 1104 adopts hydraulic damping structure, suction cup 1105 has a diameter of 120mm and a vacuum adsorption force of up to 150N, suitable for smooth surfaces such as glass and ceramic tiles.

[0063] 4. Lighting and positioning system (1) LED searchlight assembly 6 The heat dissipation base 601 adopts a copper-aluminum composite structure and is equipped with three high-brightness LEDs (1200lm luminous flux), which can be quickly installed and removed via clips 602. The light assembly supports 0~120° tilt adjustment and is equipped with an infrared sensor switch that automatically turns on when the ambient illuminance is below 50lx.

[0064] (2) Horizontal positioning system The main body 1 of the device integrates an electronic level (accuracy ±0.01°), and the data is displayed in real time on an OLED screen. When the horizontal error exceeds 0.05mm / m, the system issues a buzzer alarm to guide the user to correct the level by adjusting the fixed leg 3.

[0065] Example 4 In another preferred embodiment, based on embodiments 1, 2, and 3 above, this embodiment provides a working method for an adjustable indium steel ruler support stand. The method involves using the aforementioned adjustable indium steel ruler support stand for measurement work, and the specific steps are as follows: Step 1: Terrain Adaptation Adjustment Based on the measured ground conditions, press the unlock button 101 on the top of the device body 1 to release the ratchet mechanism 7 from locking the fixed leg 3. Roughly adjust the height of the fixed leg 3 through the adjustment hole 304, while stretching or compressing the movable leg 9. Use the buffer spring 903 and buffer pad 905 of the movable leg 9 to adapt to the uneven ground. Observe the level on the device body 1 or use an external measuring tool to ensure that the levelness error of the device body 1 does not exceed 0.05mm / m. After the adjustment is completed, release the unlock button 101, and the ratchet mechanism 7 will automatically lock the height of the fixed leg 3.

[0066] Step 2: Ground fixing operation For soft surfaces: Select the foot spike assembly 5, rotate the adjusting nut 502 to extend the spike body 503 to a suitable length, step on the foot pedal 4 to insert the spike body 503 into the ground, and achieve stable fixation of the stand.

[0067] For smooth, hard surfaces: Select the suction cup assembly 11 and press the feet to make the suction cup 1105 firmly adhere to the ground. Use the shock absorber 1104 to reduce the impact of external vibrations. If you need to enhance the anchoring force, you can install the foot spike assembly 5 and the suction cup assembly 11 at the same time to improve the fixing effect.

[0068] Step 3: Lighting and Accessories Installation When measuring in a dimly lit environment, take out the LED searchlight assembly 6 and attach it to the slot 102 using the clip 602. Turn on the LED searchlight 603 and fine-tune the lighting angle using the steering bearing 1101 as needed. When there is sufficient light, turn off the LED searchlight 603 or disassemble the LED searchlight assembly 6 for storage.

[0069] Place the indium steel ruler 12 and measuring accessories into the groove on the front side of the main body 1 of the device. The elastic buffer layer 2 protects the indium steel ruler 12 and accessories from collision. Slide the baffle 8 by pulling the operating handle 802 until the indium steel ruler 12 is completely fixed. The spring positioning pin 801 automatically positions the baffle 8 to prevent displacement.

[0070] Step 4: Measurement process adjustment and locking If the tripod height needs to be adjusted during the measurement process, repeat the unlocking and adjustment operation in step 1, and lock it after ensuring that the main body 1 of the device is horizontal; if the measurement position needs to be changed, disassemble the foot nail assembly 5 or the suction cup assembly 11, move the tripod and then fix it again. The entire operation can be completed by one person and takes no more than five minutes.

[0071] Example 5 In another preferred embodiment, based on embodiments 1 to 4 above, this embodiment provides a working method for an adjustable indium steel ruler support stand, which is used for measurement work. The specific steps are as follows: Step 1: Extend and position the supporting leg During operation, first press the unlock button 101 to extend the three support legs outward to the desired angle. The reset device 703 of the ratchet mechanism 7 precisely engages with the ratchet teeth 706 to achieve unidirectional positioning, ensuring the stability of the support legs after extension.

[0072] Step 2, Terrain Adaptation and Fixation: Depending on the terrain, either the spike assembly 5 or the suction cup assembly 11 can be installed. On soft ground, the spike body 503 of the spike assembly 5 is inserted into the ground, and the grip is enhanced by rotating the adjusting nut 502; on smooth, hard surfaces, the suction cup assembly 11 is used for adhesion and fixation.

[0073] Step 3: Height Adjustment and Locking Step on the extended foot pedal 4 on the side of the end of the movable leg, and at the same time press the pin head 906 of the spring positioning pin. After sliding the movable leg 9 to the target height, release the pin head 906 so that it is inserted into the variable spacing adjustment hole array 304 of the fixed leg 3 to achieve a stable lock.

[0074] Step 4: Installation and fixing of the invar steel ruler: Push the baffle 8 to open the rectangular slot of the main body 1 of the device, place the indium steel ruler into the slot, and then slide the baffle 8 to clamp the ruler. Raise the pull-out operating handle 802 and lock the baffle position through the guide slider 801 to ensure the stability of the indium steel ruler during the measurement process.

[0075] Step 5, Levelness Calibration and Measurement: The height of the movable leg is finely adjusted using the adjustment hole 304, and the built-in bubble calibration device of the indium steel ruler 12 is used to accurately calibrate the level of the main body 1 of the device, ensuring measurement accuracy.

[0076] After confirming that the ratchet mechanism 7 is locked securely, start the level instrument to collect data.

[0077] Step 6, Setting up lighting for nighttime operations: When working at night, an LED searchlight assembly 6 is installed on top of the main body of the device. The heat dissipation base 601 is secured by a quick-release clip 602, and the angle of the searchlight 603 is adjusted to provide directional lighting and ensure clear visibility of the measurement work.

[0078] Step 7: Completion of the assignment and packing up: After the operation is completed, disassemble the searchlight 603 and the indium steel ruler 12. Press the unlock button 101 to disengage the reset device 703, and manually fold the support legs to the storage position. Unscrew the adapter 10 and store it in the storage box. Place the entire device in a portable case for transportation and storage.

[0079] Example 6 In another preferred embodiment, based on embodiments 1 to 5 above, this embodiment provides a working method for an adjustable indium steel ruler support stand, which is used for measurement work. The specific steps are as follows: Step 1: Terrain Adaptation Adjust the lengths of the fixed leg 3 and the movable leg 9 flexibly according to the ground conditions to make the main body 1 of the device horizontal. In specific operation, depending on the measured ground conditions, press the unlock button 101 on the top of the main body 1 to release the ratchet mechanism 7 from locking the fixed leg 3. Coarsely adjust the height of the fixed leg 3 through the adjustment hole 304, while stretching or compressing the movable leg 9. Use the buffer spring 903 and buffer pad 905 of the movable leg 9 to adapt to the uneven ground. Carefully observe the level on the main body 1 or use external measuring tools for auxiliary calibration to ensure that the levelness error of the main body 1 is strictly controlled within the range of no more than 0.05mm / m. After adjustment, release the unlock button 101, and the ratchet mechanism 7 will automatically lock the height of the fixed leg 3.

[0080] For slopes or uneven ground, the movable legs 9 of each support leg are adjusted to different heights, and the level on the main body 1 of the device is used for real-time calibration until the required levelness is achieved.

[0081] Step 2: Fixing device When working on soft surfaces, the sharp spikes 503 of the spike assembly 5 can be easily inserted into the ground. By rotating the adjusting nut 502, the extension length of the spikes 503 can be precisely adjusted to enhance grip and ensure the stability of the device on soft surfaces. When working on smooth, hard surfaces, the suction cup assembly 11 uses its strong suction to adhere to the surface. Pressing the foot makes the suction cup 1105 firmly adhere to the ground. The shock absorber 1104 reduces the impact of external vibrations, ensuring that the suction cup is in close contact with the surface without the formation of air bubbles, thus providing stable support. If a hard surface is required and enhanced anchoring is needed, the foot spike assembly 5 and the suction cup assembly 11 can be used simultaneously; the dual fixing method significantly improves the stability of the device and ensures the smooth progress of the measurement operation.

[0082] Step 3: Lighting Setup and Installation Depending on the lighting conditions of the work environment, decide flexibly whether to turn on the LED searchlight assembly 6; When measuring in dim environments or working at night, take out the LED searchlight assembly 6 and attach it to the slot 102 using the clip 602. Turn on the LED searchlight 603 and fine-tune the lighting angle and brightness as needed using the steering bearing 1101 to provide directional and sufficient illumination, ensuring clear visibility and accuracy of the measurement work. After the work is completed or when there is sufficient light, turn off the LED searchlight 603 to save energy and extend its service life, or disassemble the LED searchlight assembly 6 for storage in a safe location to avoid damage or loss.

[0083] Step 4: Installation and adjustment of indium steel ruler 12 Place the indium steel ruler 12 and measuring accessories into the groove on the front side of the main body 1 of the device. The elastic buffer layer 2 protects the indium steel ruler 12 and accessories from collision. Slide the baffle 8 by pulling the operating handle 802 until the indium steel ruler 12 is completely fixed. The spring positioning pin 801 automatically positions the baffle 8 to ensure that the indium steel ruler is tightly fitted with the groove without shaking or displacement, so as to provide stable support and protection. The height of the fixed leg 3 is locked by the ratchet mechanism 7 to ensure the stability of the device during the measurement process; when adjustment is needed, press the unlock button 101 to release the lock, adjust to the required height, and then lock it again. The level of the main body 1 of the device is further fine-tuned by using the built-in bubble calibration device of the indium steel ruler 12; by observing the position and movement of the bubble, the level of the device is precisely adjusted to ensure that the measurement accuracy reaches the highest standard.

[0084] Step 5: Measurement process adjustment and locking If the tripod height needs to be adjusted during the measurement process, repeat the unlocking and adjustment operation in step 1, and lock it after ensuring that the main body 1 of the device is horizontal; if the measurement position needs to be changed, disassemble the foot nail assembly 5 or the suction cup assembly 11, move the tripod and then fix it again. The entire operation can be completed by one person and takes no more than five minutes.

[0085] Example 7 In another preferred embodiment, based on embodiments 1 to 6 above, this embodiment provides an adjustable indium steel ruler support bracket, which is used in the smoothness testing of high-speed rail tracks, as detailed below: I. Implementation Scenarios In a high-speed railway track smoothness testing project, high-precision measurements of the track's geometric parameters are required to ensure the safety and comfort of train operation. The testing site has complex terrain, including both soft soil sections and smooth concrete sections, which places high demands on the stability and adaptability of the measuring tripod.

[0086] II. Equipment for Implementation The adjustable indium steel ruler support frame mentioned above includes components such as the main body 1, ratchet mechanism 7, fixed leg 3, movable leg 9, suction cup assembly 11, foot spike assembly 5, and LED searchlight assembly 6.

[0087] III. Implementation Steps Step 1: Terrain Adaptation -Upon arriving at the testing site, the adjustable indium steel ruler support bracket was placed in a suitable position beside the track. By observing the level on the main body 1 of the device, and in conjunction with external measuring tools, it was found that the current ground was soft soil with a certain slope.

[0088] Press the unlock button 101 on the top of the main body 1 to release the locked state of the ratchet mechanism 7. At this time, since the unlock button 101 is installed at the vertical end of the T-shaped linkage rod 701, when pressed, the support rod 705 (set as a triangular support structure, with the two lower supports being bent structures) straightens and extends when the middle support is pushed downward, squeezing and pushing the return spring 704 connected to it outward, thereby driving the reset device 703 connected to the end of the return spring 704, thus unlocking the ratchet mechanism 7.

[0089] Adjust the lengths of the fixed leg 3 and the movable leg 9. The axial positioning structure 301 of the fixed leg 3 is connected to the ratchet mechanism 7. The guide groove 302 is connected to the axial positioning structure 301 through the threaded interface 303. The adjustment hole 304 on the guide groove 302 can be used to adapt to different terrains and achieve height adjustment. A guide block 904 is provided on the upper part of the movable leg 9. Sliding balls 901 are evenly distributed around the radial circumference of the guide block 904 to facilitate the extension and retraction of the movable leg 9. At the same time, the lower end of the guide block 904 is connected to the base 902. A pin head 906 is slidably installed on the base 902. The pin head 906 is connected to a buffer pad 905. The buffer pad 905 is installed inside the base 902 and is connected to a buffer spring 903. The other end of the buffer spring 903 is fixed to the inner wall of the base 902. Through the extension and retraction and buffering of the movable leg 9, it adapts to uneven ground and keeps the main body 1 of the device in a horizontal state, ensuring that the levelness error does not exceed 0.05mm / m.

[0090] Step 2: Fixing device Since the current ground is soft soil, foot spike assembly 5 is selected for fixation. The upper part of the connecting base 501 of foot spike assembly 5 is connected to the movable leg 9 via the adapter 10, and the lower part is connected to the spike body 503 via the adjusting nut 502. By rotating the adjusting nut 502, the extension and retraction of the spike body 503 is controlled, and the spike body 503 is inserted into the ground to enhance the stability of the device.

[0091] Step 3: Lighting Setup The testing site is dimly lit, so the LED searchlight assembly 6 needs to be turned on to provide illumination. The clip 602 of the LED searchlight assembly 6 is installed in the groove 102 on the rear side of the main body 1 of the device. The LED searchlight assembly 6 is installed on the rear side of the main body 1 of the device. The clip 602 is connected to the heat dissipation base 601. The LED searchlight 603 is installed on the heat dissipation base 601. Turning on the LED searchlight 603 provides sufficient illumination for the measurement work.

[0092] Step 4: Installation of Invar steel ruler 12 The indium steel ruler 12 and its accessories are assembled into a groove on the front side of the main body 1. A set of independently sliding baffles 8 are installed in the groove on the front side of the main body 1. Spring positioning pins 801 are provided on the upper and lower edges of the baffles 8. A spring 8012 is fixed inside the housing 8011 of the spring positioning pins 801. A ball column 8013 (a solid part with a hemisphere above the lower cylinder) is fixed above the spring 8012. A pull-out operating handle 802 is installed on the outer side, with a fan-shaped block at the end of the handle 802. By pulling the operating handle 802, the baffles 8 slide, fixing the indium steel ruler 12 in the groove and positioning it with the baffles 8 to ensure the stability of the indium steel ruler 12.

[0093] Step 5: Sections and Locks After confirming that the main body 1 of the device is horizontal and the invar ruler 12 is stably installed, the height of the fixed leg 3 is locked using the ratchet mechanism 7. The central rotating shaft 707 of the ratchet mechanism 7 is rotatably mounted inside the main body 1 of the device. An axial positioning structure 301 is fitted in the middle of the central rotating shaft 707, and ratchet gears 706 are installed at both ends. A set of reset devices 703 is installed above the ratchet mechanism 7, and the reset devices 703 are connected to the linkage rod 701. A radial limiting structure 702 is installed in the middle of the linkage rod 701. When the fixed leg 3 is adjusted to a suitable height, the ratchet gears 706 cooperate with the relevant components to lock, ensuring the stability of the device. If further adjustment is needed, the unlock button 101 can be pressed again to release the lock.

[0094] The entire operation was completed by a single person, taking approximately four minutes, and required no professional training. Using this adjustable indium tinplate ruler support frame, the smoothness testing of high-speed rail tracks was successfully completed in complex terrain. The measurement data was accurate and reliable, meeting the requirements for high-precision measurement.

A set of reset devices 703 is installed above the ratchet mechanism 7, and the reset devices 703 are connected to the linkage rod 701. A radial limiting structure 702 is installed in the middle of the linkage rod 701. The above configuration ensures the stable rotation of the ratchet mechanism 7 within the device body 1, and provides reset power to the ratchet mechanism 7 through the reset device 703. The radial limiting structure 702 effectively restricts the radial sway of the linkage rod 701, thereby enhancing the working stability and service life of the ratchet mechanism 7.

[0109] In a preferred embodiment, the linkage rod 701 is configured as a T-shaped structure, hollow inside with three open ends, and a support rod 705 is installed inside. A return spring 704 is installed at each of the three ends of the support rod 705. The other ends of the three return springs 704 are respectively connected to an unlock button 101 and a set of reset devices 703. The unlock button 101 is installed at the vertical end of the T-shaped linkage rod 701. This configuration allows the unlock button 101, when pressed, to push the support rod 705 to slide inside the T-shaped linkage rod 701 via the return springs 704, thereby triggering the reset devices 703 and realizing the unlocking and reset functions of the mechanism. The structure is compact and easy to operate.

[0110] In a preferred embodiment, the support rod 705 is configured as a triangular support structure, with the two lower supports being bent structures. When the middle support is pushed downwards, it straightens and extends, compressing and pushing the reset spring 704 connected to it outwards, thereby driving the reset device 703 connected to the end of the reset spring 704. This configuration effectively enhances the stability and reset efficiency of the overall structure. When the external force is removed, the reset spring 704 releases energy, driving the reset device 703 to quickly return to its original position, while the bent support rod 705 returns to its original shape, ensuring the device's rapid response and reusability.

[0111] In a preferred embodiment, a set of independently sliding baffles 8 are installed in the groove of the main body 1 of the device. Spring positioning pins 801 are provided on the upper and lower edges of the baffles 8, and a pull-out operating handle 802 is provided on the outer side.

The suction cup 1105 is used to adhere to a smooth surface, enhancing the stability of the device. The above configuration allows the device to flexibly adjust the angle via the steering bearing 1101 when it needs to adhere to a smooth surface at different angles or with an inclination. At the same time, the shock absorber 1104 effectively buffers external vibrations, ensuring that the suction cup 1105 adheres firmly, improving the overall adsorption effect and ease of use.

[0115] In the preferred embodiment, in step 1, the levelness error of the main body 1 is ensured to be no more than the required value of 0.05 mm / m by observing the level on the main body 1 or by using an external measuring tool. The above settings can ensure the stability and accuracy of the main body of the device during the installation process, avoid the accumulation of deviations in subsequent operations, and thus ensure the operating efficiency and data accuracy of the overall system.

[0116] In the preferred embodiment, in step 2, when the surface is hard and additional fixation is required, the foot spike assembly 5 and the suction cup assembly 11 can be used simultaneously to enhance the anchoring force of the device. The above settings not only ensure the stability of the device in various complex environments, but also improve the flexibility of use through modular design. Users can quickly adjust the fixing method according to actual needs to achieve an efficient and safe operation process.

[0117] In the preferred embodiment, the fixed leg 3 and the movable leg 9 are made of stainless steel, which has high strength and good corrosion resistance, and can adapt to various harsh environments; their surfaces are finely polished, which not only improves the aesthetics, but also effectively prevents scratches and wear, ensuring the durability of the movable leg 9.

[0118] In summary, the adjustable indium steel ruler support tripod and its working method provided by this invention effectively solve the technical deficiencies of traditional tripods in terms of adaptability to complex terrain, ease of adjustment, functional integration, and stability. Through structural innovation and functional integration, this device achieves reliable support for measurement systems requiring sub-millimeter precision, while also breaking through the dependence of traditional equipment on the professional skills of operators. It provides an efficient solution for high-precision engineering measurement scenarios such as high-speed rail track smoothness testing and dam settlement observation.

[0119] This invention achieves a dual breakthrough in support system and adjustment mechanism: it adopts an adjustable double-layer sleeve stainless steel support leg 9 structure, combined with longitudinal guide groove 302 and variable spacing adjustment hole 304 design, which not only realizes flexible adjustment of support height, but also significantly enhances overall rigidity through steel load-bearing structure; the integrated ratchet mechanism 7 and elastic buffer layer 2 constitute a composite protection system, which effectively isolates external vibration interference while ensuring the reliability of mechanical positioning; the pioneering dual-mode adapter component of foot spike assembly 5-suction cup assembly 11 can quickly switch the support mode under different terrain conditions through quick conversion connector 10, and with the extended anti-slip foot pedal design 4, it greatly improves the efficiency of field operation.

[0120] In terms of functional expansion, the modular design concept is consistently applied: the quick-release LED searchlight assembly 6 adopts an independent heat dissipation base 601 and a snap-fit ​​structure 602, which not only meets the lighting needs for nighttime operations but also enables quick assembly and disassembly of the lighting module; the composite fixing system consisting of the mechanical locking of the baffle 8 and the elastic buffer layer 2 effectively improves the stability of the indium steel ruler 12; the modular interface system supports the quick replacement of various measuring devices, expanding the application range of the device and improving equipment utilization. Through the collaborative working mechanism of the spring positioning pin assembly and the variable pitch adjustment hole 304, and the linkage control system of the ratchet mechanism 7 and the unlocking button 101, the free switching between coarse and fine adjustment of height adjustment and the synchronous unlocking of the support legs are realized, greatly simplifying the operation process.
