Description

Technical Field

[0001] The utility model relates to an escape indicator light for a subway safety exit, belonging to the technical field of safety marking and emergency management. Background Art

[0002] In the design and operation of subway systems, safety is always a key factor in ensuring smooth operation, and emergency exit signs are a crucial component of public transportation safety systems. In emergencies, passengers must quickly and accurately locate safe exits, and emergency exit signs play a crucial role. They not only provide clear escape directions but also buy valuable time and opportunity for safe evacuation in times of crisis.

[0003] At present, the LED circuit board of the traditional emergency exit escape indicator light is usually set on the bottom edge or back plate, such as Figure 1 The illustrated emergency exit indicator light comprises a light-transmitting plate 1, an LED circuit board 11, and a back shell 4. The back shell is provided with third and fourth through holes 15, 16. The back shell 4 is secured to a wall mounting base by screws inserted through the third and fourth through holes 15, 16. The LED circuit board 11 is placed on the bottom edge of the back shell 4. Wires 17 extend upward and pass through second wiring holes 14 for connection to an external power source. The light-transmitting plate 1 is fixedly fastened to the back shell 4. The emergency exit indicator light emits light through the light-transmitting plate 1 via the LED circuit board 11, providing guidance in dark environments. This type of emergency exit indicator light has a simple installation structure and is relatively inexpensive, making it widely used in subway structures. However, existing emergency exit indicators have several drawbacks. In the presence of water or humid weather, water can seep into the circuit board or wire connectors, causing circuit failure. Such failures not only affect the indicator light's proper operation, preventing it from providing accurate escape guidance to passengers, but can also further endanger passenger safety.

[0004] Therefore, it is necessary to design a new type of subway emergency exit escape indicator light that is waterproof and moisture-proof, which can effectively prevent water from seeping into the circuit in the subway operation environment, and at the same time has strong durability, so as to meet the requirements of waterproof, moisture-proof and durability during the operation of the subway system.

[0007] There are two brackets, and the two brackets respectively hold the two ends of the LED circuit board.

[0008] The fixing screw is also fixed on the mounting base of the wall through the fourth through hole.

[0009] A second wiring through hole is provided on the back shell, and a first wiring through hole opposite to the second wiring through hole is provided on the waterproof back plate.

[0010] The lower end of the vertical plate extends downward to a position lower than the first wiring through hole, and a slot is provided at the lower end of the vertical plate. The wires of the LED circuit board extend downward and pass through the slot, and then extend upward and pass through the slot, the first wiring through hole and the second wiring through hole in sequence.

[0011] The wire extends from the LED circuit board and passes through the card slot twice, and the wire is bent into a dripping bend structure.

[0012] A first bending portion is provided at the bottom of the vertical plate, and the clamping slot is opened on the first bending portion.

[0013] The water retaining eaves includes a horizontal plate portion connected to the top end of the waterproof back plate and a second bent portion connected to the horizontal plate portion, and the second bent portion extends downward.

[0014] An upwardly extending convex plate portion is provided at the edge of the supporting plate.
