Description

Technical Field

[0001] This invention belongs to the field of advertising light box technology, and more specifically, relates to an outdoor waterproof and windproof advertising light box. Background Technology

[0002] Outdoor advertising light boxes, as a crucial infrastructure for urban outdoor media, are widely used in various public outdoor spaces such as main and secondary roads, residential communities, industrial parks, commercial districts, leisure squares, and bus stops, thanks to their diverse designs, excellent lighting effects, flexible deployment, and wide applicability. They serve not only as a core medium for businesses to promote their brands and products but also as an important channel for disseminating public service slogans, civic messages, and government information, playing an indispensable role in urban image building and commercial media promotion.

[0003] To adapt to the flexible deployment and multi-location rotation requirements of outdoor venues, most existing mobile outdoor advertising light boxes have undergone structural optimization. They are equipped with casters at the bottom of the base, enabling rapid short-distance relocation, precise on-site placement, and fine-tuning. This significantly reduces manual handling costs and improves the efficiency of light box relocation, adapting to the needs of multi-scene, high-frequency deployment operations. Simultaneously, to adapt to the complex outdoor climate and cope with year-round wind and rain, conventional outdoor advertising light boxes are equipped with a counterweight water tank structure. By injecting clean water or counterweight water into the tank, the overall weight of the base is increased, lowering the light box's center of gravity and improving its wind resistance, reducing the probability of tipping over in strong winds. Furthermore, the core components of existing light boxes, such as the lighting strips, base shell, and mounting brackets, are all made of waterproof materials and combined with a basic waterproof sealing structure, effectively resisting rainwater erosion and penetration, meeting the requirements for all-weather waterproof outdoor use.

[0004] Outdoor public spaces often have uneven ground conditions, including indentations, slopes, potholes, and uneven ground settlement. When light boxes are placed directly on the ground using their casters, the supporting base is prone to unevenness, with one side hanging off the ground or the entire light box tilting. This tilting completely disrupts the original balanced load-bearing structure, shifting the center of gravity and significantly reducing the stability of the device. Furthermore, when stationary, the light boxes rely entirely on the casters for support and positioning. These casters are movable, and even with mechanical locking mechanisms, their locking and limiting capabilities are limited. When encountering strong lateral winds, sudden gusts, accidental pedestrian contact, or impacts from external objects, the locked casters are still prone to slight slippage, loosening, and deviation, causing the light box to shift or move. These problems of poor ground adaptability and unstable caster positioning create a vicious cycle, reducing the overall wind resistance and safety of the outdoor advertising light boxes. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an outdoor waterproof and windproof advertising lightbox. This solution addresses the issue of uneven ground conditions in outdoor public spaces, including uneven surfaces, localized slopes, potholes, and uneven ground settlement. When the lightbox is placed directly on the ground using its casters, the supporting base is prone to one-sided suspension and overall tilting. This tilting completely disrupts the original balanced force structure, causing a shift in the center of gravity and a significant decrease in stability. Furthermore, when the advertising lightbox is stationary, it relies entirely on the casters for support and positioning. Since the casters are movable, even with a mechanical locking mechanism, their locking and limiting capabilities are still significantly limited. When encountering strong outdoor winds with continuous lateral thrust, sudden gusts, or external interference such as accidental touches by pedestrians or collisions with foreign objects, the locked moving rollers are still prone to slight slippage, loosening, and deviation, which in turn causes the lightbox to shift or move. The aforementioned problems of poor ground adaptability and unstable positioning of the moving rollers are compounded and create a vicious cycle, reducing the overall wind resistance stability and safety of outdoor advertising lightboxes.

[0006] An outdoor waterproof and windproof advertising light box includes a support base, movable casters, a counterweight water tank, a mounting bracket, and an advertising billboard. Two support mechanisms are provided on both sides of the support base. Each support mechanism includes a support base, a guide adjustment hole, a locking positioning threaded hole, a locking screw, and wear-resistant and anti-slip support pads. Two small level bulbs are fixedly installed on the outside of the support base. One small level bulb is located between the two support mechanisms on the same side, and the other small level bulb is located between the two support mechanisms on both sides.

[0007] Preferably, the support base is located outside the bearing base, the guide adjustment hole is located inside the support base, and the openings at both ends of the guide adjustment hole communicate with the outside of the support base. The locking and positioning threaded hole is located inside the guide adjustment hole and communicates with the outside of the support base. The locking screw is threadedly connected inside the locking and positioning threaded hole. The lifting adjustment rod is slidably connected inside the guide adjustment hole. Wear-resistant and anti-slip support pads are located at the lower end of the lifting adjustment rod. The support height can be flexibly adjusted according to the height difference of the outdoor ground, and the moving roller is lifted off the ground to avoid the problem of the moving roller slipping and ensure the stability of the light box support.

[0008] Preferably, the bearing base is provided with an installation mechanism for each support base. Each installation mechanism includes a fixed mounting base, a positioning mounting slot, a connecting extension rod, an assembly through hole, an alignment connection hole, a fastening bolt, and a lock nut. The fixed mounting base is fixedly installed on the outside of the bearing base. The positioning mounting slot is opened on the side of the fixed mounting base near the support base. One end of the connecting extension rod is snapped into the inside of the positioning mounting slot, and the other end of the connecting extension rod is fixedly installed on the outside of the support base. There are two assembly through holes, which are opened at the upper and lower ends of the fixed mounting base and communicate with the inside of the positioning mounting slot. The alignment connection hole is opened at the end of the connecting extension rod corresponding to the assembly through hole. The fastening bolt is slidably connected inside the two assembly through holes and the alignment connection hole. The lock nut is threadedly connected to the outside of the fastening bolt. By adopting a combination of snap-fit ​​and fastening bolt locking nut, the support mechanism can be quickly disassembled and positioned. The disassembly and assembly operation is simple, which facilitates equipment transportation, storage, and parts maintenance, and improves the overall flexibility of use.

[0009] Preferably, an L-shaped limiting plate is fixedly installed on one side of each small level bubble on the support base. The small level bubble is attached to the inner side of the L-shaped limiting plate, and the L-shaped limiting plate is used to limit and fix the small level bubble.

[0010] Preferably, each wear-resistant and anti-slip support pad has several anti-slip and friction-increasing protrusions fixedly installed on its lower surface. These protrusions increase the friction of the contact surface, further enhancing anti-slip and anti-displacement capabilities, and strengthening the wind resistance stability of the light box.

[0011] Preferably, each wear-resistant and anti-slip support pad has a connecting external thread rod fixedly installed at its upper end. Each lifting and adjusting upright has a matching internal thread hole on one side corresponding to each connecting external thread rod. The connecting external thread rod is threaded into the matching internal thread hole, so that the wear-resistant and anti-slip support pad can be independently and detachably connected. The pad can be replaced individually after it is worn and aged.

[0012] Preferably, each lifting and adjusting pole is inlaid with a scale, which allows for intuitive control of the extension and retraction length of the lifting and adjusting pole, reducing manual adjustment errors and improving the leveling accuracy of the support base.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In this invention, by setting up multiple sets of support mechanisms and double small leveling bulbs, the support base can be precisely leveled, effectively adapting to complex working conditions such as uneven outdoor ground, slopes, potholes, and settlement. This avoids the problem of the support base being suspended on one side and tilting as a whole after the light box is placed on the ground. At the same time, it prevents the equipment from shaking more due to uneven force, increasing the risk of tipping over. After the lifting adjustment pole is extended, it can completely lift the moving rollers off the ground, eliminating the impact of external forces such as strong wind thrust, gust impact, pedestrian contact, and impact from foreign objects on the moving rollers. To prevent slippage and deviation, the height of the adjustable upright is fixed by locking the screw structure. The wear-resistant and anti-slip support pads with anti-slip and friction-increasing protrusions on the bottom form a mechanical interlocking structure with the ground, increasing the friction of the contact surface. The support mechanism, combined with the counterweight water tank, further lowers the overall center of gravity of the equipment. The coordinated operation of multiple structures can effectively resist the horizontal thrust and overturning moment generated by strong winds, improve the wind resistance, anti-tipping, and anti-displacement performance of the advertising light box, and comprehensively enhance the stability and safety of the equipment in complex outdoor environments.

[0014] In this invention, the extension and retraction amount can be intuitively controlled by embedding a scale on the outside of the lifting and adjusting pole, effectively reducing manual adjustment errors. The leveling process is simple and highly accurate, and the equipment leveling operation can be completed quickly, improving the work efficiency of outdoor sites.

[0015] In this invention, the support mechanism achieves rapid assembly and disassembly through an installation structure consisting of a fixed mounting base, a connecting extension rod, fastening bolts, and a locking nut. On-site, the support components can be flexibly selected for assembly and disassembly based on the deployment scenario and frequency of use. When the equipment is transported, stored, or repaired, the components can be disassembled to reduce the space occupied, adapting to different working conditions and effectively improving the overall adaptability and flexibility of the equipment.

[0016] In this invention, the wear-resistant and anti-slip support pad adopts a threaded detachable design. When the wear-resistant and anti-slip support pad suffers wear, aging, cracking, or other problems due to long-term friction and outdoor sun and rain, the support base, lifting and adjusting poles, and other supporting components can be replaced separately without disassembling them. This reduces the time and material loss caused by replacing parts and lowers the equipment operation and maintenance costs. Attached Figure Description

[0019] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0020] Please see Figures 1-8 This invention provides an outdoor waterproof and windproof advertising lightbox, comprising a support base 1, movable rollers 2, a counterweight water tank 3, a mounting bracket 4, and an advertising billboard 5. The support base 1 serves as the supporting structure for the entire lightbox. The movable rollers 2 are used for short-distance movement and relocation of the equipment, reducing the labor intensity of handling and improving the convenience of equipment transfer. The counterweight water tank 3 increases the weight of the support base 1 by filling it with water, lowering the overall center of gravity of the equipment and significantly improving the lightbox's resistance to tipping and strong winds, thus enhancing its stability when placed outdoors. The mounting bracket 4 is used to fix and support the advertising billboard 5, which serves as the main advertising display, realizing the outdoor advertising function.

[0021] Two support mechanisms are provided on both sides of the support base 1. Each support mechanism includes a support base 6, a guide adjustment hole 7, a locking positioning threaded hole 8, a locking screw 9, and a wear-resistant and anti-slip support pad 11. The support base 6 is located outside the support base 1. The guide adjustment hole 7 is located inside the support base 6. The two ends of the guide adjustment hole 7 are open and communicate with the outside of the support base 6. The locking positioning threaded hole 8 is located inside the guide adjustment hole 7 and communicates with the outside of the support base 6. The locking screw 9 is threadedly connected inside the locking positioning threaded hole 8. The lifting adjustment rod 10 is slidably connected inside the guide adjustment hole 7. The wear-resistant and anti-slip support pad 11 is located at the lower end of the lifting adjustment rod 10.

[0022] The support base 6 serves as the main mounting base for the support mechanism. The guide adjustment hole 7 provides a vertical guide for the lifting adjustment rod 10, limiting its left-right and front-back offset and ensuring that the lifting adjustment rod 10 can only slide vertically up and down, thus achieving smooth height adjustment. The locking positioning threaded hole 8 provides a threaded installation point for the locking screw 9, which, together with the locking screw 9, enables the threaded feed locking function, providing a structural basis for locking the lifting adjustment rod 10. The locking screw 9, by screwing and pressing against the lifting adjustment rod 10, uses friction to lock the extension height of the lifting adjustment rod 10, achieving height locking and fixation. The lifting adjustment rod 10 achieves vertical extension height adjustment, adjusting the support height according to the ground elevation difference, completing the switching between equipment leveling and ground-free support. The wear-resistant and anti-slip support pads 11 directly contact the ground to bear the weight of the entire machine.

[0023] Each wear-resistant and anti-slip support pad 11 has several anti-slip and friction-increasing protrusions 21 fixedly installed on its lower surface. The anti-slip and friction-increasing protrusions 21 form a multi-point mechanical interlocking structure with the ground, breaking through the friction limitations of flat pads and adapting to various ground surfaces such as cement, asphalt, and soil, greatly improving anti-slip and anti-slip capabilities.

[0024] Each wear-resistant and anti-slip support pad 11 has a connecting external thread rod 22 fixedly installed at its upper end. Each lifting and adjusting upright 10 has a matching internal thread hole 23 on one side corresponding to each connecting external thread rod 22. The connecting external thread rod 22 is threaded into the matching internal thread hole 23, realizing the detachable threaded connection of the wear-resistant and anti-slip support pad 11. At the same time, it is convenient to replace the pad individually after it is worn, making maintenance convenient.

[0025] Each lifting and adjusting rod 10 is inlaid with a scale 24 on the outside, providing a visual scale reference, accurately controlling the extension and retraction of each lifting and adjusting rod 10, greatly improving the leveling accuracy and avoiding manual adjustment errors.

[0026] Two small level bulbs 12 are fixedly installed on the outside of the support base 1. One small level bulb 12 is located between the two support mechanisms on the same side, and the other small level bulb 12 is located between the support mechanisms on both sides. The small level bulbs 12 can intuitively determine the tilt direction and tilt amplitude of the support base 1, providing a reference for precise leveling.

[0027] Each of the supporting bases 1 has an L-shaped limiting plate 20 fixedly installed on one side corresponding to each small level bubble 12. The small level bubble 12 is attached to the inner side of the L-shaped limiting plate 20, and the L-shaped limiting plate 20 limits the small level bubble 12.

[0028] Each support base 6 is provided with an installation mechanism corresponding to the support base 1. Each installation mechanism includes a fixed mounting base 13, a positioning mounting groove 14, a connecting extension rod 15, an assembly through hole 16, an alignment connection hole 17, a fastening connection bolt 18, and a locking nut 19. The fixed mounting base 13 is fixedly installed on the outside of the support base 1. The positioning mounting groove 14 is opened on the side of the fixed mounting base 13 near the support base 6. One end of the connecting extension rod 15 is engaged inside the positioning mounting groove 14, and the other end of the connecting extension rod 15 is fixedly installed on the outside of the support base 6. There are two assembly through holes 16, which are opened at the upper and lower ends of the fixed mounting base 13 and communicate with the inside of the positioning mounting groove 14. The alignment connection hole 17 is opened at the end of the connecting extension rod 15 corresponding to the assembly through hole 16. The fastening connection bolt 18 is slidably connected inside the two assembly through holes 16 and the alignment connection hole 17. The locking nut 19 is threadedly connected to the outside of the fastening connection bolt 18.

[0029] The fixed mounting base 13 serves as the connecting base between the support base 6 and the bearing base 1. The positioning mounting groove 14 pre-positions the connecting extension rod 15 to achieve rapid alignment and assembly. The connecting extension rod 15 extends the distance between the support base 6 and the fixed mounting base 13, preventing the support mechanism from affecting the movement of the moving roller 2. The alignment connection hole 17 and the assembly through hole 16 are precisely matched to provide a through channel for the fastening connection bolt 18. The fastening connection bolt 18 and the locking nut 19 cooperate to achieve rigid locking and fixing of the fixed mounting base 13 and the connecting extension rod 15.

[0030] Working principle: First, the end of the connecting extension rod 15 is snapped into the inside of the positioning mounting groove 14. The fastening connecting bolt 18 is slidably connected to the inside of the two assembly through holes 16 and the alignment connecting hole 17. The locking nut 19 is threaded to the outside of the fastening connecting bolt 18, completing the fixed assembly between the support base 6 and the bearing base 1, realizing the overall installation and fixation of the support mechanism. The lifting adjustment rod 10 is inserted into the guide adjustment hole 7. The matching internal thread hole 23 at the bottom of the lifting adjustment rod 10 is aligned with the connecting external thread rod 22 at the top of the wear-resistant and anti-slip support pad 11. The wear-resistant and anti-slip support pad 11 and the lifting adjustment rod 10 are firmly connected by screwing in the thread. At this time, the wear-resistant and anti-slip support pad 11 is installed. The small level bubble 12 is attached to the outside of the L-shaped limiting plate 20. The positioning and limiting effect of the L-shaped limiting plate 20 is used to ensure that the level bubble is attached flat. Then, it is fixed to the outside of the bearing base 1 with glue to provide a reference for subsequent equipment leveling operations. The second step involves manually pushing and pulling the lifting adjustment rods 10, allowing them to slide up and down inside the guide adjustment holes 7 of the support base 6. Combined with the scale 24 embedded on the outside of the lifting adjustment rods 10, the extension and retraction height of the four lifting adjustment rods 10 is controlled, causing the bottom wear-resistant and anti-slip support pads 11 to rise and fall, ensuring that the four wear-resistant and anti-slip support pads 11 are in complete and tight contact with the ground. Simultaneously, the bearing base 1 is lifted, causing the moving rollers 2 at the bottom of the bearing base 1 to lift off the ground, completely eliminating the displacement hazard caused by the sliding of the moving rollers 2. After the initial height adjustment is completed, the locking screw 9 is threaded into the locking positioning threaded hole 8. The locking screw 9 is then tightened so that its end tightly abuts against the surface of the lifting adjustment rods 10. The friction of the threaded locking is used to fix the extension and retraction position of the lifting adjustment rods 10, preventing them from sliding or shifting under force.

[0031] Thirdly, outdoor placement sites generally have uneven ground and uneven slopes, which can easily cause the lightbox to tilt and shift its center of gravity, leading to problems such as shaking, tipping, and distortion of the advertising image. The dual-level bubble multi-point calibration structure can achieve high-precision leveling of the equipment. Two sets of small level bubbles 12 are symmetrically arranged on both sides of the equipment support base 1, which can monitor the levelness of the support base 1 from all directions. After the initial height is fixed, the positions of the bubbles of the two small level bubbles 12 are observed in real time to determine the tilt direction and tilt range of the support base 1. If one side of the equipment is too high or too low, the locking screw 9 of the support mechanism at that position is loosened. According to the scale value of the scale 24, the extension height of the lifting adjustment pole 10 is slightly adjusted to accurately correct the tilt deviation of the support base 1 until the bubbles of the two sets of level bubbles are in the centered standard position, ensuring that the support base 1 is completely level in both the horizontal and vertical directions. This completely adapts to uneven outdoor ground, eliminates problems such as one side of the lightbox being suspended, uneven force, equipment shaking, and tilting, and evenly distributes the overall force of the equipment, greatly improving the stability of the entire machine. The fourth step, after completing the precise leveling operation, involves tightening all the locking screws 9 of the support mechanism one by one, reinforcing the clamping pressure between the locking screws 9 and the lifting adjustment rods 10. The multi-threaded self-locking structure completely locks the working height of all the lifting adjustment rods 10, preventing loosening and height deviation of the locking screws 9 during long-term outdoor use, thus ensuring the long-term stability of the equipment support structure. Simultaneously, the wear-resistant and anti-slip support pads 11, with multiple sets of anti-slip and friction-increasing protrusions 21 evenly distributed on their lower surface, form a tight multi-point engagement structure with the ground under the pressure of the equipment's own weight. This increases the contact friction between the pads and different outdoor surfaces such as cement, asphalt, and soil, effectively suppressing slippage and displacement caused by external forces. This design enhances the overall anti-slip performance of the machine. Combined with the built-in counterweight water tank 3 in the support base 1, the addition of water increases the weight of the equipment's bottom, lowering the overall center of gravity and fundamentally improving its anti-overturning capability. Therefore, in harsh outdoor environments with strong winds and gusts, multiple symmetrically arranged support mechanisms form a stable four-point support system. This, along with the wear-resistant and anti-slip support pads 11 with their ground-engaging anti-slip structure and the counterweight water tank 3 with its center-of-gravity-lowering structure, creates a triple protection system of mechanical locking, ground engagement, and counterweight stabilization. This effectively counteracts the horizontal thrust and vertical overturning moment of the wind acting on the advertising billboard 5, disperses the swaying stress caused by the wind, and achieves long-term outdoor waterproof, anti-slip, wind-resistant, and stable operation of the equipment.
