Description

Technical Field

[0001] The utility model relates to the technical field of emergency lighting fixtures, in particular to an explosion-proof fire emergency lighting fixture. Background Art

[0002] Fire emergency lighting fixtures are used to provide illumination for evacuation and fire rescue operations when normal lighting systems fail due to a fire or other emergency. During a fire, thick smoke and darkness can make evacuation extremely difficult. Emergency lighting fixtures illuminate key locations such as evacuation routes, stairwells, and emergency exits, guiding people out of a building safely and quickly.

[0003] In the event of a fire or utility power outage, the luminaire's controller quickly detects the power change and switches to emergency mode. The battery begins discharging, powering the luminaire's light source. The LEDs illuminate, illuminating key areas such as evacuation routes, emergency exits, and stairwells. These bright lights provide clear escape routes, allowing people to evacuate in an orderly manner along the illuminated pathways.

[0004] In the prior art, some explosion-proof fire emergency lighting fixtures are assembled using bolts. Installers must first take the bolts and insert them, one by one, through the mounting holes on the base and the corresponding holes in the installation area. This process requires ensuring the bolts fit accurately within the holes, and each bolt must be manually screwed onto a nut. Installers must carefully turn the nuts and tighten them gradually. This bolt-by-bolt installation process is extremely time-consuming, significantly impacting assembly efficiency. Therefore, to address these shortcomings, explosion-proof fire emergency lighting fixtures have been proposed to address these issues. Utility Model Content

[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figures 2 to 4 The present invention provides an embodiment of an explosion-proof fire emergency lighting fixture, comprising a base plate 1 and a cover plate 2. The base plate 1 serves as the basic support and installation platform for the entire fixture, providing a stable bearing foundation for various electronic components, transmission mechanisms, and sealing mechanisms inside. The cover plate 2 cooperates with the base plate 1 to form a sealed fixture cavity, protecting the internal components from the influence of the harsh external environment. The left and right ends of the cover plate 2 are slidably connected to a quick-release mechanism, which facilitates the rapid removal and installation of the cover plate 2 during the installation, maintenance, and inspection of the fixture, thereby improving work efficiency. The rear side of the inner wall of the base plate 1 is fixedly connected to a sealing mechanism, which is a key part in achieving the explosion-proof performance of the fixture. Through a special sealing structure and elastic elements, the interior of the fixture is completely isolated from the external environment, preventing flammable and explosive gases or dust from entering the interior of the fixture and causing danger. The left and right sides of the cover plate 2 are fixedly connected to a grip plate 3, which facilitates the operator to hold and apply force when installing, disassembling, or adjusting the fixture. The top of the base plate 1 is threadedly connected to two transmission mechanisms, which are responsible for stably transmitting electrical energy to the lighting lamp head 17;

[0034] The quick-release mechanism includes a push plate 4, and the outer parts of the two push plates 4 are respectively slidably connected to the inner walls of the left and right ends of the cover plate 2, so that the push plates 4 can move stably inside the cover plate 2. The rear side of the push plate 4 is fixedly connected to a transmission plate 5, which transmits the movement of the push plate 4 to subsequent components. The opposite ends of the transmission plates 5 are fixedly connected to transmission columns 6, which serve as force transmission and conversion components to transmit the force exerted on the transmission plates 5 to subsequent components. An inclined opening 7 is provided inside the right-angle plate 8, and the inclined opening 7 is used to limit the movement of the transmission column 6. The outer part of the transmission column 6 is slidably connected to the inside of the inclined opening 7, so that the sliding of the transmission column 6 in the inclined opening 7 can drive the right-angle plate 8 to move in a specific direction. The outer part of the transmission column 6 is slidably connected to the right-angle plate 8, and the opposite end of the transmission plate 5 is slidably connected to the inside of the two right-angle plates 8, further enhancing the linkage relationship between the transmission plate 5 and the right-angle plate 8;

[0035] The upper and lower sides of the right-angle plate 8 are fixedly connected with side blocks 9, which provide an installation base and movement guide for the subsequent reset assembly. The two side blocks 9 are internally slidably connected with a reset assembly for resetting the side blocks 9. The reset assembly can restore the relevant components to their initial positions after the quick-release operation is completed. The reset assembly includes a positioning column 10, which serves as a guide for the reset assembly. Its external sliding connection is inside the two side blocks 9, so that the positioning column 10 can move stably inside the side blocks 9. The external sleeve of the positioning column 10 is provided with a spring 11 to limit the spring 11 so that the spring 11 can be evenly stressed. The adjacent sides of the two side blocks 9 are respectively fixedly connected to the far ends of the spring 11, which determine the installation position and force direction of the spring 11.

[0036] Reference Figure 1 、 Figure 2 and Figure 5 The sealing mechanism includes a plurality of springs 2 12, and the rear ends of the plurality of springs 2 12 are fixedly connected to the rear side of the inner wall of the base plate 1, ensuring that the rear ends of the springs 2 12 are stable and reliable. The front ends of the plurality of springs 2 12 are fixedly connected with a sealing ring 13, which is in close contact with the rear side of the cover plate 2 under the action of the spring 2 12, thereby achieving sealing inside the lamp. The outer portion of the sealing ring 13 is slidably connected to the inner wall of the base plate 1, so that the sealing ring 13 can move stably inside the base plate 1. An annular opening 14 is provided inside the base plate 1, which provides the necessary space and guidance for the movement of the sealing ring 13. The front side of the sealing ring 13 is in contact with the rear side of the cover plate 2, ensuring the sealing effect. The base plate 1 and the cover plate 2 are both made of aluminum alloy, which has good strength, corrosion resistance and explosion-proof performance, and can effectively protect the internal components of the lamp and adapt to harsh fire emergency environments.

[0037] The transmission mechanism includes a threaded head 15, which serves as a connecting component between the transmission mechanism and the base plate 1. Its threaded connection method facilitates the installation and disassembly of the transmission mechanism. The outer parts of the two threaded heads 15 are respectively threadedly connected to the left and right ends of the top of the base plate 1, ensuring the stable installation of the transmission mechanism on the base plate 1. The interior of the threaded head 15 is fixedly connected to a protective tube 16, which provides physical protection for the internal transmission components such as wires to prevent them from being damaged by external squeezing, collision or corrosion. The front end of the protective tube 16 is fixedly connected to a lighting lamp head 17, which is the light-emitting component of the lamp. The bottom end of the lighting lamp head 17 is fixedly connected to a support plate 18, which provides support for the lighting lamp head 17.

[0038] Working principle: The operator holds the grip plates 3 on both sides of the cover plate 2 with both hands, and then presses the push plate 4 inward at the same time. During the pressing process, the push plate 4 will push the transmission plate 5 to slide, thereby driving the transmission column 6 to slide. At this time, the inclined opening 7 opened inside the right-angle plate 8 will guide the transmission column 6, so that the transmission column 6 can push the right-angle plate 8 to slide. During the sliding process, the right-angle plate 8 will also drive the side block 9 to slide and squeeze the spring 11, so that the spring 11 can store elastic potential energy, and then give the right-angle plate 8 a force in the opposite direction to reset. As the right-angle plate 8 slides, it slides until it is no longer engaged with the bottom plate 1. At this time, the bottom plate 1 and the cover plate 2 can be quickly removed. On the contrary, the thrust on the push plate 4 is released. At this time, the spring 11 will reset and transmit the reset force to the right-angle plate 8 and engage with the inside of the bottom plate 1, thereby completing quick disassembly and assembly, thereby improving assembly efficiency.

[0039] As the base plate 1 and the cover plate 2 are installed, the cover plate 2 will also press against the sealing ring 13 and squeeze multiple springs 12, so that the springs 12 can store elastic potential energy, and then give the springs 12 an opposite direction to press against the base plate 1, thereby achieving sealing and cooperating with the aluminum alloy material of the base plate 1 and the cover plate 2, so that it has explosion-proof performance and meets the requirements for use in explosion-proof environments.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
