Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment, and in particular to smoke-proof fire emergency lighting fixtures. Background Technology

[0002] As a key component of modern building fire safety systems, fire emergency lighting fixtures play a crucial role in providing illumination guidance for personnel evacuation and firefighting operations during emergencies such as fires. Their reliability directly impacts the safety of people and the extent of property loss. With the increasing intelligence and complexity of buildings, the functional and safety requirements for emergency lighting fixtures are becoming increasingly stringent, especially the ability to operate stably and continuously in smoke-filled fire environments, which has become a vital indicator of product quality.

[0003] Most fire emergency lighting fixtures on the market today adopt a modular assembly structure, integrating core components such as the light source, battery, and control circuit into a metal or plastic casing, and are assembled using conventional fixing methods such as clips and screws. The fixture casing is usually designed with heat dissipation holes and installation interfaces. In response to fire environments, some products are equipped with an independent emergency power switching device, which is triggered by smoke and heat detectors to ensure automatic switching to backup power supply in the event of a main power failure.

[0004] However, existing fire emergency lighting fixtures have obvious structural design flaws. Their sealing components rely solely on static pressure for physical bonding. In high-temperature, high-airflow fire environments, gaps easily form at the connection between the fixture's outer shell and the lampshade due to thermal expansion and contraction, vibration, and other factors. Once smoke enters the fixture through these gaps, it can not only cause short circuits in the light source and circuit board but also reduce the light transmittance of the fixture due to smoke accumulation, severely affecting the emergency lighting effect and failing to meet the urgent need for continuous and reliable lighting during fire evacuation. Therefore, smoke-proof fire emergency lighting fixtures are proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides smoke-proof fire emergency lighting fixtures, which aim to improve the problem that in the event of a fire, smoke and dust can easily enter the interior through the product's joint gaps, affecting the normal operation of the product.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Smoke-proof fire emergency lighting fixtures include a lamp fixture, a lamp cover is provided on one side of the lamp fixture, the lamp fixture and the lamp cover are connected and fixed by screws, and a smoke-proof component and a quick-release component are provided on the outer wall of the lamp fixture; The smoke-proof component includes a sealing ring located at the connection between the lampshade and the lamp.

An activated carbon plate is fixedly connected inside the sealing ring.

[0007] As a further description of the above technical solution: The quick-release assembly includes multiple connecting posts and locking blocks, which are located on the outer wall of the lamp, and a connecting plate is fixedly connected to one side of the lamp.

[0008] As a further description of the above technical solution: A fixing plate is provided on one side of the connecting plate, and one end of each of the connecting columns is fixedly connected to the outer wall of the fixing plate.

[0009] As a further description of the above technical solution: Both sides of the inner wall of the connecting plate are fixedly connected to the connecting shell, and each connecting shell is slidably connected to the transmission block.

[0010] As a further description of the above technical solution: One side of each of the transmission blocks extends through to the outside of the connecting shell and is fixedly connected to a pressing plate, while the other side of each of the transmission blocks is fixedly connected to the outer wall of the card block.

[0011] As a further description of the above technical solution: Multiple connecting posts are slidably connected inside the connecting shells on both sides, and each locking block engages with the interior of the connecting post on the adjacent sides.

[0012] As a further description of the above technical solution: Each of the card blocks is fixedly connected to a connecting plate 2 at its bottom, and each of the connecting shells is fixedly connected to a fixing plate 2 at the bottom of its inner wall.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 , Figure 4 and Figure 5The present invention provides an embodiment of a smoke-proof fire emergency lighting fixture, including a lamp 12. The lamp 12 is equipped with an independent emergency power switching device, which is triggered by a smoke and heat detector to ensure that the main power supply fails and the backup power supply continues to provide power. This is prior art and will not be described in detail here. A lamp cover 1 is provided on one side of the lamp 12. The lamp 12 and the lamp cover 1 are connected and fixed by screws. The outer wall of the lamp 12 is provided with a smoke-proof component and a quick-release component. The smoke-proof component includes a sealing ring 15, which is located at the connection between the lampshade 1 and the lamp fixture 12. The sealing ring 15 is used to prevent external smoke and dust from entering the lamp fixture 12, achieving a sealing and smoke-proof effect. A connecting shell 13 is fixedly connected to the outer wall of the lampshade 1. A spring plate 14 is provided inside the connecting shell 13. The spring plate 14 is used to provide elastic pressure to ensure that the sealing ring 15 and the lamp fixture 12 fit tightly. Multiple spring plates 14 are fixedly connected to the outer wall of the sealing ring 15 on one side and to the inner wall of the connecting shell 13 on the other side. The spring plates 14 cooperate with the sealing ring 15 to perform elastic compression movement, thereby enhancing the sealing effect. An activated carbon plate 16 is fixedly connected inside the sealing ring 15. The activated carbon plate 16 is used to adsorb smoke and dust that enters through the gaps, thereby purifying the internal air.

[0020] Reference Figures 1-3The quick-release assembly includes multiple connecting posts 5 and locking blocks 8, located on the outer wall of the lamp 12. The connecting posts 5 are used to fix the connecting shell 4, achieving stable installation. A connecting plate 2 is fixedly connected to one side of the lamp 12, and a fixing plate 3 is provided on one side of the connecting plate 2. One end of each connecting post 5 is fixedly connected to the outer wall of the fixing plate 3. Connecting shells 4 are fixedly connected to the inner walls of both sides of the connecting plate 2. The connecting shells 4 accommodate transmission blocks 7 and locking blocks 8, achieving transmission and limiting functions. A transmission block 7 is slidably connected inside each connecting shell 4, transmitting the pressure of the pressing plate 6 and driving the locking blocks 8 to move. One side of each transmission block 7 extends through to the outside of the connecting shell 4 and is fixedly connected to the pressing plate 6, which receives external pressure and triggers the quick-release mechanism. The other side of each transmission block 7 is fixedly connected to the outer wall of the locking block 8, which is used for engaging the connection. The column 5 enables quick fixing and disassembly. Multiple connecting columns 5 are slidably connected inside the connecting shells 4 on both sides. Each locking block 8 engages with the interior of the adjacent connecting column 5 on both sides. The locking block 8 cooperates with the connecting column 5 to perform locking movements, achieving the effect of quick installation and disassembly. Each locking block 8 has a connecting plate 9 fixedly connected to its bottom. The connecting plate 9 is used to connect the spring strip 10 and transmit elastic force. Each connecting shell 4 has a fixing plate 11 fixedly connected to its bottom inner wall. The fixing plate 11 is used to fix the spring strip 10 and provide support. Each connecting shell 4 has multiple spring strips 10 inside. The spring strips 10 are used to provide elastic restoring force to ensure that the locking block 8 automatically returns to its position. The top of each spring strip 10 is fixedly connected to the bottom of the connecting plate 9, and the bottom of each spring strip 10 is fixedly connected to the top of the fixing plate 11. The spring strips 10 cooperate with the locking block 8 to perform elastic restoring movements, achieving the effect of automatic locking.

[0021] Working principle: During the product sealing process, the lampshade 1 is moved to one side of the lamp fixture 12. At this time, the outer wall of the lampshade 1 will push the activated carbon plate 16 to slide inside the connecting shell 13, and compress the spring plate 14. Utilizing the elasticity of the spring plate 14, the compressive force is rebounded to the outer wall of the sealing ring 15, so that the sealing ring 15 fully compresses and fits the lamp fixture 12 and the lampshade 1, thereby sealing the connection between the lampshade 1 and the lamp fixture 12. In addition, the activated carbon plate 16 absorbs the smoke and dust that enters the product through the connection gap between the lampshade 1 and the lamp fixture 12, ensuring that the smoke and dust will not affect the inside of the product. This achieves a good smoke prevention effect and solves the problem that smoke and dust can easily enter the inside of the product through the connection gap in the event of a fire, affecting the normal operation of the product, and enhances the smoke prevention effect of the product. During product disassembly and repair, the worker presses down on the pressing plate 6, which drives the locking block 8 to move downward through the transmission block 7. As the locking block 8 moves, it squeezes the spring strip 10 through the connecting plate 2 9. After the locking block 8 is completely separated from the inner wall of the connecting post 5, the connecting shell 1 4 is pulled, causing the connecting shell 1 4 to separate from the outer wall of the connecting post 5 on the side of the fixing plate 1 3. This separates the connecting plate 1 2 on the side of the lamp 12 from the outer wall of the fixing plate 1 3. After the product repair is completed, the connecting plate 1 2 is moved back to the side of the fixing plate 1 3, and the connecting shell 1 4 is inserted into the outer wall of the connecting post 5. The rebound force of the spring strip 10 pushes the locking block 8 to re-lock into the inner wall of the connecting post 5, thus achieving product installation and fixation. This achieves a good disassembly effect and solves the problem that traditional products usually require the use of special tools to unscrew the screws on the product surface when disassembly and repair is needed, which is time-consuming. This enhances the portability of product disassembly.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
