Technical Field
[0001] The utility model relates to the technical field of indicator signs, specifically an evacuation indicator sign. Background Art
[0002] An evacuation indicator sign, also known as an evacuation indication sign or a safety exit indicator light, is a lighting device installed in public places such as shopping malls, office buildings, hospitals, schools, etc., which is used to provide evacuation directions and indications for people in case of emergencies (such as fires). These indicator signs usually use high-brightness and durable LED light sources, and can continue to emit light through a backup power source (such as a battery) even in the event of a power outage, ensuring continuous lighting and indication for people in case of emergencies.
[0003] An evacuation indicator sign mainly consists of LEDs (light-emitting diodes). An LED is a semiconductor light-emitting element with characteristics such as high efficiency, energy saving, long life, fast startup, and no pollution. An evacuation indicator sign usually has several LEDs to ensure the brightness and intensity of the light emitted by the lamp. The circuit part of the evacuation indicator sign mainly includes two parts: a control circuit and a driving circuit. The control circuit is used for the self-check and automatic switching functions of the indicator light to ensure that the lamp can work normally in case of emergencies. The driving circuit provides the required current and voltage for the LEDs to ensure the normal light emission of the LEDs. The external structure of the evacuation indicator sign usually includes one or more panels, on which indication arrows, texts, etc. are printed to indicate the evacuation direction and the location of the safety exit. The panel material is usually fireproof and corrosion-resistant to ensure reliability and durability in case of emergencies.
[0004] However, when installing the existing evacuation indicator signs, they are directly fixed on the wall through glue or fixing bolts. When maintenance or replacement of the indicator signs is required, it may be necessary to damage the wall or perform complex disassembly work, increasing the maintenance cost and difficulty.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention.
[0031] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.
[0032] The evacuation indicator board, as Figures 1-6 shown, includes a lamp board body 1. A fixed frame 2 is snap-fitted on the outside of the lamp board body 1. Clamping blocks 14 are movably installed at both ends of the lamp board body 1 in a symmetrical structure. Grooves for cooperating with the clamping blocks 14 are provided in the fixed frame 2. Driving gears 6 are rotatably connected to the outside of the fixed frame 2 in a left-right symmetrical structure. A transmission gear 16 is fixedly connected to the bottom of the driving gear 6. A rack 8 for cooperating with the transmission gear 16 is movably connected in the fixed frame 2. Card slots 22 for cooperating with the rack 8 are provided on both sides of the lamp board body 1. A second spring 19 is fixedly connected to the bottom of the clamping block 14.
[0033] During installation, first reserve an installation groove on the wall, then fix the fixed frame 2 in the installation groove, then retract the clamping block 14 into the lamp board body 1 by the performance of the second spring 19 itself, and then snap the lamp board body 1 into the fixed frame 2. When the lamp board body 1 is completely snapped into the fixed frame 2, the clamping block 14 snaps into the groove, which can play a preliminary limiting role for the lamp board body 1. Then, by rotating the driving gear 6, due to the meshing relationship between the transmission gear 16 and the rack 8, the rack 8 can be inserted into the lamp board body 1. The rack 8 can flexibly move in the lamp board body 1 through the card slots 22 in the lamp board body 1. With this structure, the lamp board body 1 can be flexibly fixed on the wall for use. Through the indicator lights on the lamp board body 1, the effect of indicating and guiding can be achieved. With this structure, it can solve the technical problem in the prior art that when installing the evacuation indicator board, it is directly fixed on the wall through glue or fixing bolts. When the indicator board needs to be maintained or replaced, it may be necessary to damage the wall or perform complex disassembly work, increasing the maintenance cost and difficulty, and improving the practicability and flexibility of the entire evacuation indicator board.
[0034] When further disassembly and repair of the lamp board body 1 are required, hold the slider 5 and slide it inward at the same time. Through the mutual cooperation between the connecting block 15 and the connecting rod 9, the first movable block 10 can move towards the clamping block 14 at the same time until the clamping block 14 is extruded out of the fixed frame 2. Then release the slider 5. When no pressure is applied to the slider 5, due to the performance of the first spring 17 itself, the connecting rod 9 and the first movable block 10 can be quickly reset. Through the provided chute 7, the slider 5 can slide on the fixed frame 2, so that through the mutual cooperation between the connecting block 15 and the connecting rod 9, the first movable block 10 can move within the fixed frame 2. Through the movable cavity, the first movable block 10 and the convex block 11 can move up and down within the fixed frame 2, so as to flexibly extrude the clamping block 14 out of the fixed frame 2.
[0035] In this embodiment, the limiting block 4 made of rubber material enables the lamp board body 1 to be tightly clamped within the fixed frame 2. Through the friction between the rubber and the lamp board body 1, the lamp board body 1 can be more stably connected to the fixed frame 2. The provided sealing cover 3 can protect the slider 5 and the driving gear 6. The mutual cooperation between the fixed block 18 and the telescopic rod 24, when a special situation occurs, through the control structure within the fixed block 18, the telescopic rod 24 drives the second movable block 12 to extend out of the lamp board body 1, and the lighting lamp 13 on the second movable block 12 provides light source, thereby improving the visibility and enhancing the practicality of the lamp board body 1. Secondly, through the movable groove 23, the second movable block 12 can flexibly move within the lamp board body 1. Finally, the provided bottom plate 20 protects the structure within the lamp board body 1, and through the mutual cooperation between the clamping column 21 and the clamping groove 22, the bottom plate 20 can be flexibly connected to and disassembled from the lamp board body 1.
