Description

Technical Field

[0001] This utility model belongs to the field of sign technology, specifically a luminous emergency sign. Background Technology

[0002] In the vast outdoor spaces, illuminated emergency signs act like beacons in the darkness, guiding people towards safety. These devices stand silently in every corner of the city, safeguarding public safety with their steady light. They are not merely simple directional tools, but an indispensable and vital component of the modern urban safety system.

[0003] The design of outdoor illuminated emergency signs takes into full account the complex and ever-changing outdoor environment. Whether in the scorching summer sun or the biting winter wind, these devices maintain stable and reliable performance. They can withstand wind and rain, remaining clearly visible even in adverse weather conditions. Special protective designs ensure normal operation even in extreme temperatures, providing reliable protection for safe evacuation in emergencies. Intelligence is a significant feature of outdoor illuminated emergency signs. These devices can sense environmental changes and automatically adjust their operating status. During the day, they maintain low power consumption; at night or when visibility is reduced, they automatically increase their brightness. Through linkage with urban safety systems, they can provide dynamic guidance in emergencies, optimize evacuation routes, and improve emergency response efficiency. The innovative design of the energy system enables outdoor illuminated emergency signs to operate truly autonomously. They can operate continuously using clean energy, reducing dependence on the traditional power grid. Even during prolonged periods of continuous rain, they can maintain stable operation. This self-sufficient energy solution is not only environmentally friendly and energy-saving, but more importantly, it ensures continuous functionality during emergencies.

[0004] The existing illuminated emergency signs have the following main shortcomings:

[0005] Existing illuminated emergency signs can only accommodate a single sign at a time, and the fixed nature of this single structure limits their spatial adaptability. Current devices typically employ a single, fixed unit design, making flexible configuration impossible based on site conditions. This fixed location results in insufficient usability. Traditional signs are permanently installed and cannot be moved once fixed, making them unsuitable for temporary locations or frequently changing layouts. Furthermore, the fixed height affects visual recognition; existing products have a fixed installation height and cannot be optimized for different usage scenarios and user characteristics. Research shows that the optimal recognition height for directional signs is closely related to the average eye level of observers. Fixed-height designs fail to meet the visual needs of people of different heights, especially in environments with obstructions, where the directional effect is significantly reduced.

[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0026] like Figures 1-5 As shown, this utility model provides a technical solution:

[0027] A luminous emergency sign includes:

[0028] The counterweight base plate 1 has four self-locking casters 2 at its bottom. The main body shell 3 is rotatably connected to the counterweight base plate 1. A triangular slider 4 is slidably connected inside the main body shell 3. An internal threaded seat 5 is fixedly connected to one side of the triangular slider 4. An adjustment mechanism is set inside the main body shell 3. The counterweight base plate 1 itself has a large mass, which can ensure the overall stability of the device. In addition, the self-locking casters 2 at the bottom of the counterweight base plate 1 can move the device flexibly, making it more flexible and adaptable to space.

[0029] The adjustment mechanism includes a threaded rod 6 rotatably connected to the bottom of the main body shell 3. The threaded rod 6 is threadedly connected to the internal threaded seat 5. A driven bevel gear 7 is coaxially fixedly connected to the threaded rod 6. An active bevel gear 8 is rotatably connected to the inner wall of the main body shell 3. The active bevel gear 8 and the driven bevel gear 7 mesh with each other. A height adjustment knob 9 is rotatably connected to the side wall of the main body shell 3.

By rotating the height adjustment knob 9, the active bevel gear 8 can be driven. When the active bevel gear 8 rotates, the driven bevel gear 7 that meshes with it will rotate. Then the threaded rod 6, which is coaxially fixedly connected to the driven bevel gear 7, will rotate. Through the connection of the internal threaded seat 5, the height of the triangular slider 4 can be adjusted, and the height of the indicator on the triangular slider 4 can be adjusted naturally.

[0030] A slot is provided on the side of the triangular slider 4 away from the internal thread seat 5. Multiple mounting blocks 10 are fixedly connected at equal intervals in the slot. An indicator mounting seat 11 is movably connected to the triangular slider 4. A quick-installation mechanism is provided in the indicator mounting seat 11. In actual use, if necessary, multiple indicator mounting seats 11 can be installed on the triangular slider 4 to meet complex usage scenarios. The mounting blocks 10 provide support for multiple installations of the indicator mounting seats 11.

[0031] The quick-installation mechanism includes a notch on one side of the sign mounting base 11, which cooperates with the mounting block 10. Two limiting plates 12 are fixedly connected to the inner wall of the sign mounting base 11. Two mating toothed plates 13 are slidably connected inside the sign mounting base 11. The limiting plates 12 are slidably connected to the mating toothed plates 13 on their corresponding sides. The mating plates 13 are fixedly connected to mating plates 14 on their opposite sides. An installation knob 15 is rotatably connected to the sign mounting base 11. The shaft of the installation knob 15 passes through the sign mounting base 11. A torsion spring is provided on the side wall of the sign mounting base 11. The shaft of the installation knob 15 is connected to the torsion spring.

The quick-installation mechanism is designed to quickly install and remove the sign, reducing installation and removal costs. During actual installation, the installation knob 15 can be rotated. When the installation knob 15 is rotated, the coaxially fixedly connected mating gear 16 will rotate, causing the two meshing gear plates 13 to move closer or further apart. The limiting plate 12 ensures the stability of the mating gear plates 13 during sliding. When the mating plate 14, which is fixedly connected to the mating gear plate 13, is furthest away, the notch on one side of the sign mounting base 11 is aligned with the mounting block 10, and the installation knob 15 is released. Under the action of the torsion spring, the mating plate 14 can fit against the outer surface of the triangular slider 4. In addition, when disassembling, the installation knob 15 can be reversed.

[0032] The working principle of this utility model is as follows:

[0033] The counterweight base plate 1 itself has a large mass, which can ensure the overall stability of the device. In addition, the self-locking casters 2 are installed at the bottom of the counterweight base plate 1, which can move the device flexibly, making it more flexible and adaptable to space.

[0034] By rotating the height adjustment knob 9, the driving bevel gear 8 can be driven. When the driving bevel gear 8 rotates, the driven bevel gear 7 that meshes with it will rotate. Then the threaded rod 6 that is coaxially fixed to the driven bevel gear 7 will rotate. Through the connection of the internal thread seat 5, the height of the triangular slider 4 can be adjusted, and the height of the indicator on the triangular slider 4 can be adjusted naturally.

[0035] In practical use, multiple indicator mounting seats 11 can be installed on the triangular slider 4 if needed to meet complex usage scenarios. The mounting block 10 provides support for multiple installations of the indicator mounting seats 11. The quick-installation mechanism is designed to quickly install and remove the indicator to reduce installation and removal costs. During actual installation, the installation knob 15 can be rotated. When the installation knob 15 is rotated, the coaxially fixedly connected mating gear 16 will rotate, and the two meshing gear plates 13 will move closer or further apart. The limit plate 12 ensures the stability of the mating gear plates 13 during sliding. When the mating plate 14, which is fixedly connected to the mating gear plates 13, is furthest away, align the notch on one side of the indicator mounting seat 11 with the mounting block 10 and release the installation knob 15. Under the action of the torsion spring, the mating plate 14 can fit against the outer surface of the triangular slider 4. In addition, when disassembling, simply reverse the installation knob 15.

[0036] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
