A protective structure for a panoramic mobile lighting fixture

Abstract

This utility model discloses a protective structure for a panoramic mobile lighting fixture, including a central tube frame. A telescopic component is fixedly installed at the upper end of the central tube frame, and a lighting component is fixed to the top of the telescopic component with screws. Beneficial effects: The modular chassis, composed of three fan-shaped panels, combined with precise positioning by a positioning plate and positioning posts, significantly increases the contact area with the ground, distributing the overall weight and effectively reducing the impact of center of gravity shift. The outriggers and the modular chassis are connected by angled insertion holes, forming a multi-directional stable support system based on the chassis's own counterweight. Even on uneven ground, this reduces swaying or tilting, significantly enhancing anti-tipping capabilities. The large contact area design of the modular chassis increases ground friction, better resisting horizontal thrust from wind. While meeting storage and folding requirements, it also offers reliable support and good wind resistance.

Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and more specifically, to a protective structure for a panoramic mobile lighting lamp. Background Technology

[0002] In scenarios such as nighttime construction, emergency rescue, and large-scale events, panoramic mobile lighting is a key piece of equipment providing wide-area, high-brightness illumination, and its stable operation directly affects work efficiency and safety. To meet the needs of mobile use, these lights typically require a portable support structure to achieve height adjustment, angle fixation, and overall stable placement.

[0003] Currently, most mainstream panoramic portable lighting fixtures on the market use a tripod design for their support structure. This structure offers advantages in portability due to its simple structure, small folded size, and light weight. However, in actual use, because panoramic portable lighting fixtures are typically large and have a relatively concentrated weight, and because the fixture often requires multi-angle rotation and adjustment to achieve panoramic illumination, the overall center of gravity is prone to shift. When the center of gravity shifts beyond the tripod's stable support range, swaying or even tilting can easily occur. Secondly, the tripod's support feet have a small contact area with the ground, making it difficult for ground friction to effectively resist horizontal thrust under wind. Furthermore, the fixture creates a large windward area, and the resulting wind load, transmitted through the connecting structure to the tripod, can easily cause the tripod to sway laterally, potentially even causing the entire equipment to overturn. This not only affects the normal operation of lighting work but also poses safety hazards to surrounding personnel and equipment. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a protective structure for a panoramic mobile lighting lamp, which has the advantages of reliable support and good wind resistance, thereby solving the problems mentioned in the background technology.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned advantages of reliable support and good wind resistance, the specific technical solution adopted by this utility model is as follows: A protective structure for a panoramic mobile lighting lamp includes a central tube frame. A telescopic component is fixedly installed at the upper end of the central tube frame, and a lighting component is fixed to the top of the telescopic component by screws. A hinge sleeve is fixed to the lower surface of the central tube frame, and several legs are installed around the side of the hinge sleeve. Several rotating columns are installed around the top surface of the lighting component, and an LED light is installed on each rotating column. A mobile power supply is fixedly installed at the bottom of the central tube frame, and the output end of the mobile power supply is electrically connected to the LED light. A split chassis is provided below the mobile power supply, and the split chassis is composed of three fan-shaped panels. Each of the three fan-shaped panels has a set of positioning holes and oblique insertion holes on its surface. A positioning plate is installed at the center of the split chassis, and a positioning post is welded to the surface of the positioning plate corresponding to the positioning hole. The bottom end of the legs is inserted into the oblique insertion hole of the fan-shaped panel.

[0008] Furthermore, the bottom of the rotating column is rotatably connected to the lighting assembly via a bearing seat. Two connecting blocks are welded to the bottom of the LED light, and double-ended bolts are inserted between the two connecting blocks and the rotating column. Nuts are installed at both ends of the double-ended bolts. A rubber ring is provided in the gap between the two connecting blocks and the rotating column, and the rubber ring is sleeved with the double-ended bolts.

[0009] Furthermore, the telescopic component is specifically a pneumatic lifting telescopic rod, and the top of the telescopic component is equipped with a mounting panel with screw holes, and the bottom of the telescopic component is interference-fitted with the central tube frame.

[0010] Furthermore, the surface of the central tube frame is fitted with a clamp, and the side of the clamp is provided with several U-shaped grooves, and the several U-shaped grooves correspond one-to-one with several support legs.

[0011] Furthermore, the hinge sleeve has several U-shaped notches around its side, and each U-shaped notch is fixed with a connecting post. The connecting post of the hinge sleeve is inserted and connected to the upper end of the support leg.

[0012] Furthermore, the surface of the positioning disk is welded with a number of positioning posts, and the number of positioning posts corresponds to the positioning holes of the three fan-shaped panels respectively.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a protective structure for a panoramic mobile lighting lamp, which has the following beneficial effects:

[0015] (1) This utility model features a split chassis composed of three fan-shaped panels. With the precise positioning of the positioning plate and positioning column, the contact area with the ground is greatly increased, the overall weight is distributed, and the impact of center of gravity shift is effectively reduced. The legs are inserted into the split chassis through angled holes, and combined with the self-counterweight of the split chassis, a multi-directional stable support system is formed. Even when used on uneven ground, it can reduce swaying or tilting, and the anti-overturning ability is significantly enhanced. The large contact area design of the split chassis increases the ground friction and can better resist the horizontal thrust generated by the wind. While meeting the requirements for storage and folding, it also has the advantages of reliable support and good wind resistance.

[0016] (2) This utility model, by installing a set of rotating columns and connecting blocks between the lighting components and the LED lights, allows the lighting angle adjustment of the LED lights to be divided into two directions: horizontal and vertical. In the horizontal direction, the rotating columns drive the lamp body to rotate, achieving 360° rotation; in the vertical direction, the rotating columns and connecting blocks are used for adjustment. After loosening the nuts at both ends of the double-ended bolt, the LED lights can rotate around the double-ended bolt to adjust the pitch angle. After adjustment, tightening the nuts increases the friction of the rubber ring by compression, fixing the current angle and ensuring the stability of the lighting direction. This satisfies the multi-angle adjustment function of each LED light and can achieve 360° panoramic lighting. Attached Figure Description

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present invention, a protective structure for a panoramic mobile lighting lamp is provided.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a protective structure for a panoramic mobile lighting lamp according to an embodiment of the present invention includes a central tube frame 1. A telescopic component 2 is fixedly installed on the upper end of the central tube frame 1, and a lighting component 3 is fixed to the top of the telescopic component 2 by screws. A hinge sleeve 5 is fixed to the lower surface of the central tube frame 1, and several support legs 7 are installed around the side of the hinge sleeve 5. Several rotating columns 10 are installed around the top surface of the lighting component 3, and an LED light 4 is installed on each rotating column 10. A mobile lighting lamp is fixedly installed at the bottom of the central tube frame 1. A power supply 6 is provided, and its output terminal is electrically connected to the LED light 4. A split-type chassis 8 is located below the power supply 6. The split-type chassis 8 is composed of three fan-shaped panels 15. Each of the three fan-shaped panels 15 has a set of positioning holes 18 and oblique insertion holes 19 on its surface. A positioning plate 16 is installed at the center of the split-type chassis 8, and positioning posts 17 are welded to the surface of the positioning plate 16 corresponding to the positioning holes 18. The bottom end of the support leg 7 is inserted into the oblique insertion holes 19 of the fan-shaped panel 15. The hinge sleeve 5 is made of wear-resistant metal material. Several support legs 7 are installed around the side, made of high-strength aluminum alloy, which reduces the overall weight while providing reliable support. The LED light 4 can be adjusted to multiple angles by rotating the rotating column 10 to meet different lighting needs. The power bank 6 uses a large-capacity lithium battery pack to provide long-lasting power to the LED light 4, and its output is electrically connected to the LED light 4 to ensure stable power transmission. The split chassis 8 is an important structure for improving the equipment's wind resistance and stability. The system consists of three fan-shaped panels 15, all made of non-slip and wear-resistant engineering plastic. Each panel has a set of positioning holes 18 and angled insertion holes 19. The positioning holes 18 are used for precise positioning of the fan-shaped panel 15 and the positioning plate 16, while the angled insertion holes 19 are used for connection with the support legs 7. The positioning plate 16 is made of metal and has high structural strength. Positioning posts 17 are welded to its surface corresponding to the positioning holes 18. The cooperation between the positioning posts 17 and the positioning holes 18 ensures the integrity and stability of the assembled three fan-shaped panels 15. The bottom end of the support leg 7 is inserted into the angled insertion hole 19 of the fan-shaped panel 15. This insertion method not only facilitates installation but also allows the support leg 7 to form a stable triangular support relationship with the split chassis 8, significantly improving the stability of the equipment during placement.

[0027] Please refer to Figure 1 and Figure 2The bottom of the rotating column 10 is rotatably connected to the lighting component 3 via a bearing seat. Two connecting blocks 11 are welded to the bottom of the LED light 4, and double-ended bolts 12 are inserted between the two connecting blocks 11 and the rotating column 10. Nuts are fitted at both ends of the double-ended bolts 12. Rubber rings 13 are placed in the gap between the two connecting blocks 11 and the rotating column 10, and these rubber rings 13 are fitted onto the double-ended bolts 12. A ball bearing is installed inside the bearing seat, allowing the rotating column 10 to rotate flexibly, thereby enabling the LED light 4 to rotate horizontally. The connecting blocks 11 are fixed by welding, ensuring a firm connection with the LED light 4. Nuts are fitted at both ends of the double-ended bolts 12. By adjusting the tightness of the nuts, the vertical angle of the LED light 4 can be fixed. When it is necessary to adjust the pitch angle of the LED light 4, loosen the nuts to rotate the LED light 4 to the appropriate angle, and then tighten the nuts for stable fixation. A rubber ring 13 is provided in the gap between the two connecting blocks 11 and the rotating column 10. The rubber ring 13 is fitted with the double-headed bolt 12. The rubber ring 13 can not only increase the friction between the connecting blocks 11 and the rotating column 10 and prevent the LED light 4 from shifting due to vibration during use, but also play a buffering role and reduce the wear of the connection parts.

[0028] Please refer to Figure 1 The telescopic component 2 is specifically a pneumatic lifting telescopic rod. The top of the telescopic component 2 is equipped with a mounting panel with screw holes, and the bottom of the telescopic component 2 is interference-fitted with the central tube frame 1. Compared to traditional manual telescopic rods, it offers advantages such as easier and less effort in adjustment. It is composed of multiple nested sections of high-strength aluminum alloy / stainless steel tubing, naturally forming a through-channel to allow electrical wires to pass through. This pneumatic lifting telescopic rod achieves lifting and lowering via air pressure control. Operators can easily adjust the lamp height simply by controlling the valve, and the lifting process is smooth, effectively preventing the lamp from being impacted by sudden movements. The top of the telescopic component 2 is equipped with a mounting panel with screw holes, the size of which matches the mounting base at the bottom of the lighting component 3. The two are fixed together with screws, ensuring a secure connection and easy disassembly. The bottom of the telescopic component 2 and the central tube frame 1 are interference-fitted, ensuring no gaps between them, improving the overall structural stability, and preventing the telescopic component 2 from swaying under load.

[0029] Please refer to Figure 1 and Figure 3 The surface of the central tube frame 1 is fitted with a clamp 9, and the side of the clamp 9 is provided with several U-shaped clamping grooves, and the several U-shaped clamping grooves correspond one-to-one with several support legs 7. The clamp 9 is made of elastic metal material and has a certain degree of contraction and clamping force. When the equipment needs to be folded, the support legs 7 can be taken out from the U-shaped clamping grooves for folding. The operation is simple and convenient.

[0030] Please refer to Figure 1 and Figure 3 The hinge sleeve 5 has several U-shaped notches around its side, and each U-shaped notch contains a fixed connecting post 14. The connecting post 14 of the hinge sleeve 5 is inserted and connected to the upper end of the support leg 7. The number of U-shaped notches is the same as the number of support legs 7. Each U-shaped notch contains a fixed connecting post 14. The connecting post 14 is made of high-strength steel and is welded and fixed to the hinge sleeve 5, ensuring a firm connection. The connecting post 14 of the hinge sleeve 5 is inserted and connected to the upper end of the support leg 7, allowing the upper end of the support leg 7 to rotate freely around the connecting post 14, thus enabling the support leg 7 to unfold and fold. This connection method has a simple structure and flexible rotation, ensuring that the support leg 7 reaches a suitable angle when unfolded, guaranteeing the stability of the support structure. At the same time, the U-shaped notches also limit the rotation range of the support leg 7, preventing excessive rotation of the support leg 7 from affecting the normal use of the equipment.

[0031] Please refer to Figure 4 The positioning disk 16 has several positioning posts 17 welded to its surface, and these posts 17 correspond to the positioning holes 18 of the three sector panels 15. As the core positioning component of the split chassis 8, the positioning disk 16 has these positioning posts 17 welded to its surface. The positioning posts 17 are cylindrical and welded perpendicularly to the positioning disk 16, ensuring a strong weld and preventing them from easily falling off. The diameter of the positioning holes 18 is slightly larger than the diameter of the positioning posts 17, ensuring that the positioning posts 17 can be smoothly inserted into the holes 18. When assembling the split chassis 8, the positioning holes 18 of the three sector panels 15 are aligned with the positioning posts 17 on the positioning disk 16 and inserted. The positioning posts 17 provide precise positioning for the sector panels 15, ensuring that the three sector panels 15 can be accurately assembled into a complete circular chassis. Simultaneously, the cooperation between the positioning posts 17 and the positioning holes 18 prevents the sector panels 15 from shifting during use, ensuring the integrity and stability of the split chassis 8 and improving the equipment's anti-tipping ability during placement.

[0032] Working principle: Before use, the three fan-shaped panels 15 are connected to the positioning posts 17 of the positioning plate 16 through the positioning holes 18 to form a split chassis 8, completing the construction of the bottom foundation. Then, the support legs 7 are extended, with their upper ends rotating around the connecting posts 14 of the hinge sleeve 5 to a suitable angle, and their lower ends inserted into the oblique insertion holes 19 of the split chassis 8. Through the insertion and cooperation of the support legs 7 and the split chassis 8, and the fixing effect of the clamps 9, a stable triangular support structure is formed, providing a load-bearing foundation for the overall equipment. The telescopic component 2 adopts a pneumatic lifting telescopic rod. By controlling the valve to adjust the internal air pressure, the telescopic rod is extended and retracted, thereby changing the height of the lighting component 3. The interference fit between the bottom of the telescopic component 2 and the central tube frame 1 ensures the structural stability during the lifting process. The mounting panel with screw holes at the top evenly distributes the weight of the lighting component 3 to the central tube frame 1, avoiding local overload. The lighting angle adjustment of the LED light 4 is divided into horizontal and vertical directions. The lamp body rotates 360° horizontally via the rotating column 10. Vertically, the rotating column 10 and connecting block 11 work together for adjustment. Loosening the nuts at both ends of the double-ended bolt 12 allows the LED light 4 to rotate around the bolt 12 to adjust its pitch angle. After adjustment, tightening the nuts increases friction through compression, fixing the current angle and ensuring stable lighting direction. The power bank 6 is installed at the bottom of the central tube frame 1, transmitting power to the LED light 4 via its internal circuitry. The large-capacity lithium battery pack design ensures long battery life, and the fixed connection between the power bank 6 and the central tube frame 1 prevents poor circuit contact due to vibration during use, ensuring stable power transmission.
