Description

Technical Field

[0001] This utility model relates to the field of adjustable leveling support platform technology, and in particular, to a tripod that can be horizontally adjusted. Background Technology

[0002] Tripods, as a common support device, are widely used in measuring instruments, optical equipment, industrial processing and other fields. Their core function is to provide stable support and ensure the levelness of the load-bearing platform.

[0003] In existing technologies, traditional tripods typically rely on manual adjustment of leg length or coarse calibration using a bubble level. Some high-precision tripods employ electronic levels combined with servo motors for automatic leveling, for example, by using tilt sensors to control motors that adjust leg lengths to improve leveling accuracy. However, such solutions still have the following technical problems:

[0004] 1. The contradiction between accuracy and stability: During the initial setup, equipment installation, and equipment use, the insufficient support stability of the tripod leads to the need for frequent leveling adjustments; high-sensitivity sensors and fast-response motors or manual adjustments are easily affected by vibration or load changes when bearing heavy objects, causing the system to adjust frequently or even oscillate, which in turn reduces stability.

[0005] 2. Insufficient environmental adaptability: The thermal expansion and contraction characteristics of metallic materials may affect the horizontal reference, and existing technologies mostly rely on manual compensation or fixed calibration, making it difficult to adapt to application scenarios with large temperature variations. In addition, asymmetrical loads may cause uneven stress on the tripod, affecting the leveling effect.

[0006] 3. Cost and complexity issues: High-precision automatic leveling tripods usually rely on precision sensors and servo systems, which leads to a significant increase in manufacturing costs. They also have high requirements for the operating environment (such as power supply and dust protection), which limits their widespread application. Utility Model Content

Detailed Implementation

[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0030] Figure 1 This is a schematic diagram of the tripod structure according to a preferred embodiment of the present invention; Figure 2 This is a bottom view of the tripod structure according to a preferred embodiment of the present invention.

[0031] like Figure 1 and Figure 2As shown, the tripod in this embodiment includes a platform unit 100 and support leg units 200. Three sets of support leg units 200 are arranged at equal intervals along the circumference of the platform unit 100 and are respectively connected to the platform unit 100 to form a tripod. A level 500 is provided on the platform unit 100. A first height adjustment mechanism 300 is provided on the support end of each support leg unit 200, and a second height adjustment mechanism 400 is provided at the bottom of the platform unit 100. The first height adjustment mechanism 300 of the corresponding support leg unit 200 is adjusted according to the tilt detection result of the level 500, and the second height adjustment mechanism 400 is adjusted after being adjusted to be horizontal, so that both the first height adjustment mechanism 300 and the second height adjustment mechanism 400 touch the target position surface below, thereby realizing horizontal adjustment and horizontal support load. This utility model of a tripod achieves initial coarse adjustment of the platform unit 100's levelness through a first height adjustment mechanism 300 on the leg unit 200, and fine adjustment through the coordinated action of the first height adjustment mechanism 300 and the second height adjustment mechanism 400, forming a two-stage adjustment mechanism. This avoids the oscillation problem caused by repeated corrections from a single adjustment mechanism, ensuring both rapid level calibration and improved final adjustment accuracy. After completing the level adjustment, both the first height adjustment mechanism 300 and the second height adjustment mechanism 400 are in contact with the target position surface, forming multi-point distributed support. This evenly distributes the load to the leg unit 200 and its first height adjustment mechanism 300, and the platform unit 100 and its second height adjustment mechanism 400, reducing the risk of deformation due to single-point load-bearing and significantly improving the overall structural rigidity and anti-overturning capability. The division of labor between the two-stage adjustment mechanisms reduces reliance on individual adjustment components. More specifically, the first height adjustment mechanism 300 of the outrigger unit 200 prioritizes adapting to macroscopic deformations caused by uneven ground or temperature, while the second height adjustment mechanism 400 of the platform unit 100 compensates for microscopic deviations, thereby reducing the cumulative impact of metal thermal expansion and contraction or vibration on the horizontal state. By replacing a complex fully automatic servo system with mechanical graded adjustment, the need for precision sensors and motors is reduced while maintaining accuracy, lowering manufacturing costs and maintenance complexity, making it more suitable for harsh environments or high-load scenarios. Through the synergistic effect of the dual height adjustment mechanisms of the platform unit 100 and the outrigger unit 200, significant improvements are achieved in horizontal accuracy, support stability, environmental adaptability, and cost control. Optionally, a handle 600 is provided on the platform unit 100. Optionally, the outrigger unit 200 is detachably connected and assembled onto the platform unit 100.

[0032] like Figure 1 and Figure 2As shown, in this embodiment, the first height adjustment mechanism 300 includes a first adjusting nut 301, a first adjusting screw 302, and a first support plate 303. The first adjusting nut 301 is fixedly connected to the adjusting end of the outrigger unit 200, and the axial direction of the first adjusting nut 301 is vertically arranged. The first adjusting screw 302 is threadedly connected to the first adjusting nut 301, and the adjusting control end of the first adjusting screw 302 is at the upper end. The first support plate 303 is arranged at the lower end of the first adjusting screw 302. Alternatively, the first adjusting nut 301 is embedded in the adjusting end of the outrigger unit 200, and the axial direction of the first adjusting nut 301 is vertically arranged. The first adjusting screw 302 is threadedly connected to the first adjusting nut 301, and the adjusting control end of the first adjusting screw 302 is at the upper end. The first support plate 303 is arranged at the lower end of the first adjusting screw 302. Height adjustment is achieved through the threaded engagement of the first adjusting nut 301 and the first adjusting screw 302. The threaded drive has a self-locking characteristic, automatically maintaining its position after adjustment to prevent height deviation due to load or vibration, thus ensuring support stability. The adjustment control end of the first adjusting screw 302 is located at the upper end, allowing operators to manually adjust it directly from above without disassembling or flipping the tripod, significantly improving adjustment efficiency, especially suitable for rapid leveling needs in field or complex environments. The first support plate 303 is located at the lower end of the first adjusting screw 302, increasing the contact area with the ground or target support surface, dispersing local pressure, preventing deformation or slippage of the support surface due to excessive point load, and simultaneously improving the overall structure's anti-overturning capability. The first adjusting nut 301 can be externally fixed (e.g., welded connection, which can be connected to the lower or upper end of the adjusting end of the outrigger unit 200) for easy maintenance and replacement; alternatively, the first adjusting nut 301 can be embedded within the outrigger unit 200, reducing protruding external parts, improving structural stability, lowering the risk of collision, and enhancing overall aesthetics to meet the needs of different application scenarios. The threaded drive mechanism achieves precise height control through a finely designed pitch, and combined with feedback from the level 500, enables high-precision level calibration, meeting the installation requirements of precision instruments or equipment. The first height adjustment mechanism 300, through optimized threaded drive and support plate design, ensures adjustment accuracy while also considering ease of operation, structural stability, and environmental adaptability, effectively improving the overall performance of the tripod.

[0033] like Figure 1 and Figure 2As shown, in this embodiment, multiple sets of the second height adjustment mechanism 400 are provided, and these multiple sets of second height adjustment mechanisms 400 are arranged radially and / or circumferentially at intervals along the bottom of the platform unit 100. By arranging multiple sets of second height adjustment mechanisms 400 at intervals along the bottom of the platform unit 100, a multi-point support structure is formed, effectively dispersing the load pressure on the platform unit 100. Combined with the support leg unit 200 and the first height adjustment mechanism 300, a synergistic support effect is produced, avoiding platform deformation or tilting caused by excessive force at a single point, and significantly improving the overall support stability. The multiple sets of second height adjustment mechanisms 400 can be independently fine-tuned to achieve precise height compensation at different positions of the platform unit 100, eliminating residual tilting errors after coarse adjustment of the support leg unit 200, and ensuring that the platform unit 100 meets higher leveling accuracy requirements. For asymmetrical load conditions, the multiple sets of second height adjustment mechanisms 400 can be adjusted differently according to the actual force conditions, dynamically balancing the force distribution on the platform and preventing platform imbalance caused by eccentric loads. The distributed layout design reduces reliance on a single adjustment mechanism. Even if some adjustment mechanisms fail due to uneven ground or thermal deformation, the remaining mechanisms can still maintain the platform's levelness, enhancing the system's fault tolerance. Through a rational design of radial and circumferential arrangements, installation space is maximized while ensuring adjustment functionality, maintaining the tripod's overall lightweight and compact structure. The distributed layout of multiple sets of 400mm second height adjustment mechanisms, through spatial redundancy, achieves synergistic optimization in platform stability, adjustment accuracy, and load adaptability, effectively solving the reliability issues of traditional tripods under complex working conditions.

[0034] like Figure 1 and Figure 2As shown, in this embodiment, the second height adjustment mechanism 400 includes a second adjusting nut 401, a second adjusting screw 402, and a second support plate 403. The second adjusting nut 401 is fixedly connected to the platform unit 100, and its axial direction is vertically arranged. The second adjusting screw 402 is threadedly connected to the second adjusting nut 401, and the second support plate 403 is located at the lower end of the second adjusting screw 402. Through the precise thread engagement between the second adjusting nut 401 and the second adjusting screw 402, fine-tuning of the height of the platform unit 100 can be achieved. Combined with the coarse adjustment of the first height adjustment mechanism 300, a two-stage adjustment system is formed, significantly improving the final level accuracy. The second support plate 403 is located at the lower end of the second adjusting screw 402, increasing the contact area with the support surface, effectively dispersing the concentrated load transmitted by the platform unit 100, preventing local sinking or sliding, and ensuring stable support after adjustment. The threaded drive has a self-locking characteristic, automatically maintaining its position after height adjustment, avoiding damage caused by vibration or load. To mitigate displacement caused by load changes and ensure long-term stability of the platform, a second height adjustment mechanism 400 is integrated into the bottom of the platform unit 100, arranged vertically. This arrangement satisfies functional requirements while maximizing installation space and maintaining the compactness of the overall tripod structure. The second height adjustment mechanism 400, located on the platform unit 100, allows operators to perform intuitive fine-tuning during equipment installation, improving work efficiency. A standardized threaded pair structure facilitates manufacturing, maintenance, and replacement, reducing production costs, while allowing flexible adjustment of thread parameters according to different load requirements. Through optimized mechanical structure design, the second height adjustment mechanism 400 ensures adjustment accuracy while also considering support stability, ease of operation, and structural reliability. Working in conjunction with the first height adjustment mechanism 300, it achieves high-precision horizontal adjustment of the tripod.

[0035] like Figure 1As shown, in this embodiment, the leg unit 200 has a zigzag shape. The leg unit 200 includes an outer frame 201, an inner liner 202, and a diagonal brace 203. The outer frame 201 is a closed ring. The inner liner 202 is arranged on the inner wall of the outer frame 201 and is vertically arranged on the outer frame 201. The diagonal brace 203 is arranged on the inner side of the inner liner 202. The outer frame 201, the inner liner 202, and the diagonal brace 203 are combined to form a truss structure. The outer frame 201, inner lining frame 202, and diagonal braces 203 combine to form a closed truss structure, creating a multi-directional force-bearing system. This significantly improves the bending, torsional, and compressive strength of the leg unit 200, ensuring structural stability under high load conditions. While maintaining mechanical performance, the truss structure reduces material usage through a rational spatial layout, effectively lowering the overall weight of the leg unit 200 and improving the tripod's portability and operational flexibility. The zigzag arrangement, combined with the triangular stabilizing structure of the diagonal braces 203, forms a radially extending and downward-bending support structure for the platform unit 100. The support system enhances the dynamic stiffness of the leg unit 200, suppresses the transmission of external vibrations, and absorbs some impact energy through the elastic deformation of the truss structure, improving vibration reduction performance. The inner liner 202 is vertically arranged on the inner wall of the outer frame 201, and the diagonal braces 203 form support on the inner side, making full use of the internal space of the leg unit 200 to achieve structural reinforcement in a compact layout and avoid excessive increase in the outer diameter. The truss unit design allows for adjustment of the size of the outer frame 201 or the number of diagonal braces 203 according to different load-bearing requirements, achieving a gradient configuration of the performance of the leg unit 200. Through mechanical optimization and spatial layout optimization, the structure of the leg unit 200 has achieved significant improvements in load-bearing capacity, weight control, and environmental adaptability, ensuring the overall stability of the tripod.

[0036] like Figure 1As shown, in this embodiment, the angle of the broken line of the outrigger unit 200 is 90°-175°; and / or the vertical height of the outrigger unit 200 gradually decreases from the connecting end to the adjusting end. Controlling the angle of the broken line within the range of 90°-175° ensures both the rigid support of the outrigger unit 200 (enhancing lateral stability at small angles) and the flexibility of deployment (creating bottom clearance and operating space at large angles, providing more stable support over large angles and areas, and preventing overturning), achieving a balance between support strength and operability. The broken line angle design, by changing the geometric configuration of the outriggers, allows for adjustment of the support span for different ground conditions, increasing the contact area with the ground, preventing lateral slippage, and enhancing the tripod's anti-overturning capability. The vertical height gradually decreases from the connecting end to the adjusting end, forming a tapered load-bearing structure. This allows the leg unit 200 to achieve a stress gradient distribution when bearing vertical loads, effectively reducing the root bending moment and improving overall bending resistance. The gradually decreasing height structure reduces the mass inertia at the end of the leg unit 200, reducing the sway amplitude caused by wind loads or equipment vibrations and improving dynamic stability. The tapered leg structure reduces the space occupied at the adjusting end, avoids interference between multiple legs, and provides more room for operators to move around. The gradually decreasing height design conforms to the stress distribution characteristics of the legs, reducing material usage in low-stress areas, achieving structural weight reduction without sacrificing load-bearing capacity. Through precise control of geometric parameters, synergistic optimization is achieved in terms of mechanical performance, environmental adaptability, and human-machine interaction, resolving the technical contradiction between the insufficient rigidity of traditional straight-leg tripods and the cumbersome adjustment of folding-leg tripods.

[0037] In this embodiment, the leg unit 200 and the platform unit 100 are integrally formed; or the leg unit 200 and the platform unit 100 are integrally welded together; or the leg unit 200 is detachably connected to the platform unit 100 via positioning pins or positioning bolts 205. Integral forming or welding together eliminates assembly gaps and the risk of loosening of connectors, significantly improving the overall rigidity of the leg and platform, ensuring structural integrity under high load or vibration conditions, and is suitable for precision instrument support scenarios with stringent stability requirements. Integral forming is suitable for casting or 3D printing processes, reducing assembly steps and lowering the manufacturing cost of complex structures, making it particularly suitable for mass production. Welding together achieves high-strength bonding through localized high-temperature fusion, suitable for connecting dissimilar materials or on-site processing needs of large tripods. The integral structure completely avoids the risk of loosening, making it suitable for scenarios requiring long-term fixed use. The outrigger unit 200 and platform unit 100 are detachably connected. The modular design, using locating pins or bolts 205, allows for quick assembly and disassembly, ensuring connection accuracy while facilitating transportation and storage. Furthermore, individual components can be replaced independently if damaged, reducing maintenance costs. The detachable design of the outrigger unit 200 and platform unit 100 utilizes standardized connectors, facilitating decentralized processing and subsequent assembly, and flexibly adapting to different outrigger and platform combination requirements. The detachable connection supports quick replacement of the outrigger unit 200, allowing users to select different lengths and types of outrigger units 200 according to their usage scenarios, enhancing the tripod's functional adaptability. The detachable design achieves a balance between convenience and reliability through mechanical interlocking of locating pins / bolts and anti-loosening measures (such as thread-locking adhesive).

[0038] like Figure 1As shown, in this embodiment, the connecting end of the outrigger unit 200 is provided with a retaining groove 204. The outrigger unit 200 is embedded in the side of the platform unit 100 through the retaining groove 204 and is fixedly connected to the platform unit 100 by a positioning pin or positioning bolt 205; or the platform unit 100 is provided with a retaining groove 204 on its side, and the outrigger unit 200 is embedded in the retaining groove 204 and fixedly connected to the platform unit 100 by a positioning pin or positioning bolt 205. Through the mechanical limiting effect of the retaining groove 204, the assembly position of the outrigger unit 200 and the platform unit 100 is precisely aligned, eliminating the radial gap present in traditional bolt connections and improving the overall structural rigidity of the tripod; combined with the composite fixing method of positioning pin or positioning bolt 205, a double locking mechanism is formed, which can resist axial tensile force and prevent circumferential rotation, significantly enhancing the reliability of the connection node under vibration or impact loads. The guiding function of the mounting groove 204 eliminates the need for additional alignment adjustments during the installation of the outrigger unit 200. Combined with the positioning pins or bolts 205, it enables rapid assembly with a simple "insert and position" process, significantly improving on-site deployment efficiency. The standardized design of the groove structure and positioning components ensures accurate repositioning after disassembly and assembly, preventing loosening or accumulated positional deviations caused by repeated disassembly. The lateral contact surface of the mounting groove 204 converts the bending moment borne by the outrigger unit 200 into shear force on the platform unit 100. Compared to pure bolt connections, this better conforms to the mechanical transmission path, reducing stress concentration at the connection points. The depth and contact area of ​​the mounting groove 204 can be flexibly designed according to load requirements (e.g., deep grooves for heavy-duty tripods), achieving a gradient configuration of connection strength. The mounting groove 204 can be machined at the end of the outrigger unit 200 or on the side wall of the platform unit 100, adapting to different production processes, and the groove structure has minimal impact on surface treatment. The standard design of the positioning pins or bolts 205 facilitates later maintenance and replacement, reducing total lifecycle costs. Through the synergistic effect of mechanical fitting and fasteners, it is superior to traditional flange or socket solutions in terms of connection strength, ease of operation and process adaptability, and is especially suitable for high-precision tripod applications that require frequent disassembly and assembly.

[0039] like Figure 1 and Figure 2As shown, in this embodiment, the platform unit 100 has a through hole 101 running vertically through the middle; the platform unit 100 includes a support layer 102, a transition layer 103, and a platform layer 104 arranged sequentially from bottom to top, and the support leg unit 200 is arranged on the support layer 102; the support layer 102 includes a support upper plate 1021, a support inner sidewall 1022, a support outer sidewall 1023, and a support lower plate 1024. At least one of 023 or the supporting lower plate 1024 is a solid plate, a perforated plate or a truss plate; and / or the transition layer 103 includes a support cylinder 1031 arranged in a closed annular cylindrical shape and a bracing plate 1032 diagonally braced on the outside of the support cylinder 1031, wherein the support cylinder 1031 and / or the bracing plate 1032 are solid plate structures or truss plate structures; and / or the platform layer 104 adopts an annular horizontal plate 1041, wherein the upper surface of the annular horizontal plate 1041 is provided with a foolproof positioning pin 1042. The support layer 102 is designed with a combination of an upper support plate 1021, an inner support wall 1022, an outer support wall 1023, and a lower support plate 1024. At least one of the upper support plate 1021, the inner support wall 1022, the outer support wall 1023, or the lower support plate 1024 can be a solid plate, a perforated plate, or a truss plate (preferably, the upper support plate 1021 and the lower support plate 1024 are solid plates, and the inner support wall 1022 and the outer support wall 1023 are truss plates). Solid plates are used in key load-bearing areas (such as the connection of the leg unit 200) to ensure strength, while perforated / truss structures are used in non-load-bearing areas to reduce weight, thus achieving a balance between load-bearing capacity and lightweight. The use of perforated plates or truss plates not only has basic support and protection functions, but also functions such as weight reduction and ventilation. The closed annular support cylinder 1031 of the transition layer 103 and the diagonal brace 1032 form a spatial truss system, which is also attached vertically to the support layer 102 and the platform layer 104 to form a spatial truss system. This system can evenly transfer the load vertically. The inclination design of the diagonal brace 1032 optimizes the force flow path and avoids stress concentration. The through hole 101 design allows cables or auxiliary structures to pass through the center of the platform, and even large tripods can be accessed by operators, thereby meeting the needs of equipment wiring, adding auxiliary structures, or adding hoisting mechanisms, and improving functional expandability. The annular horizontal plate 1041 of the platform layer 104 cooperates with the foolproof positioning pin 1042 to ensure the flatness of the bearing surface and to enable the quick, accurate, and correct installation of instruments and equipment through the foolproof positioning pin 1042, preventing off-center loading caused by misoperation. The composite structure of the support layer 102 and the transition layer 103 forms a multi-level vibration reduction system. The solid plate area suppresses high-frequency vibration, and the truss structure absorbs low-frequency shaking, improving the anti-interference ability of precision instruments during operation. The vertical design of the diagonal brace 1032 and the support cylinder 1031 can be used to adjust the torsional stiffness of the platform unit 100 to adapt to different dynamic load conditions (such as periodic oscillation).The layered structure allows each layer to use differentiated processes independently, reducing the overall manufacturing difficulty of complex components. Through the optimized design of "through hole 101 and three-layer composite structure", while ensuring the core support function, it achieves a comprehensive improvement in lightweight, vibration reduction performance and functional expandability, resolving the contradiction between load-bearing capacity and multi-functional requirements of traditional tripod platforms.

[0040] like Figure 1 As shown, in this embodiment, a level 500 is provided on the upper surface of the support layer 102 on at least one side of each outrigger unit 200. Each outrigger unit 200 is equipped with a corresponding level 500, enabling real-time monitoring of the local level status of the area where each outrigger unit 200 is located. This avoids the accumulation of overall errors caused by a single level 500, significantly improving the leveling accuracy of the tripod. Combined with the first height adjustment mechanism 300 of the outrigger unit 200 and the second height adjustment mechanism 400 of the platform unit 100, a collaborative mechanism of "zonal detection-graded adjustment" is formed, achieving precise control throughout the entire process from coarse to fine adjustment. When the platform unit 100 is subjected to an eccentric load, the level 500 in the area where each outrigger unit 200 is located can independently provide tilt data, guiding differentiated adjustments of the corresponding adjustment mechanisms of the outrigger unit 200 or platform unit 100. This effectively compensates for the deformation of the platform unit 100 caused by asymmetrical loads, maintaining the overall level status. The level 500 is positioned near the connection area of ​​the outrigger unit 200, allowing operators to directly observe level changes in the corresponding area when adjusting the height of the outrigger unit 200. This reduces the need to repeatedly check the level 500, improving leveling efficiency. The distributed layout of multiple level 500s forms a redundant monitoring system. Even if a single level 500 fails, the platform status can still be determined by comprehensively analyzing data from the remaining units, enhancing system reliability, especially suitable for field or vibration environments. Optionally, the level 500 is embedded in the upper surface of the support layer 102, avoiding the protruding structure of external sensors. This protects the level 500 from impacts and keeps the platform surface flat, facilitating equipment installation. Through a spatially distributed level monitoring network, technical synergy is achieved in terms of adjustment accuracy, load adaptability, and ease of operation, solving the problems of blind spots and error amplification caused by traditional tripods relying on a single level 500.
