Description

Technical Field

[0001] This utility model relates to the field of fire emergency equipment technology, specifically a fire emergency sign with a protective shell surface to prevent cracking and breakage. Background Technology

[0002] Fire emergency signs, used for fire emergency lighting and safety exit indication, are one of the most common guiding tools in fire emergencies. They feature long emergency response time, high brightness, and automatic emergency response in case of power failure. Fire emergency signs are typically made of industrial plastics and high-brightness bulbs, primarily white in color, with directional arrows on the surface. They are characterized by non-aging materials and rapid heat dissipation. Fire emergency signs are available in wall-mounted, handheld, and hanging installation methods. Existing fire emergency signs often have a flat design, meaning the outer shell is flat and without curvature. In an emergency, the psychological tension of people inevitably leads to collisions with the fire emergency signs, causing the outer shell to break. Without the protection of the outer shell, the fire emergency signs are very fragile and may be damaged on subsequent impacts, leaving subsequent escapees without direction.

[0003] Furthermore, the application document with publication number CN217982768U mentions a fire emergency sign with a shatterproof protective shell. This utility model adds a curved outer shell and a curved inner shell. The arc-shaped curved inner shell and the curved outer shell can disperse the force to all sides when subjected to force, avoiding shell breakage. The pressure resistance and impact resistance are greater than those of traditional flat shells. It can work in emergency situations and under various impacts, improving the reliability of fire emergency signs. However, there are still some defects that need to be optimized. The specific defects are as follows: the structure protrudes too much from the wall, occupies a lot of space, which increases the risk of people colliding with the protective structure in emergency situations. Moreover, there is no cushioning design after a collision, which can easily cause people to be injured. At the same time, the protective structure itself lacks flame retardant protection, and the sign is prone to failure due to fire.

[0004] Therefore, it is particularly important to design a fire emergency sign with a protective shell surface to prevent cracking and breakage, so as to overcome the above-mentioned technical defects and improve its overall practicality. Utility Model Content

[0005] The purpose of this utility model is to provide a fire emergency sign with a protective shell surface to prevent cracking and breakage, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fire emergency sign with a protective shell surface designed to prevent cracking and breakage includes the sign itself, characterized in that: a mounting plate is provided on one side of the sign; a protective frame is provided on the outside of the sign; a U-shaped limiting block is provided inside the protective frame; an upward-opening slot is provided inside the U-shaped limiting block; a first protective plate is provided inside the slot; several fixing cylinders are provided on the other side of the U-shaped limiting block away from the sign; damping spring shock absorbers are provided inside the fixing cylinders; a second protective plate is provided at one end of the damping spring shock absorber; an clearance opening is provided at the top of the protective frame; several heat dissipation slots are symmetrically provided on both sides of the protective frame; and mounting brackets are provided at the four corners of one side of the protective frame.

[0008] As a preferred embodiment of this utility model, the mounting plate and the mounting bracket are respectively provided with mounting holes.

[0009] As a preferred embodiment of this utility model, the U-shaped limiting block and the protective frame are fixedly connected, the top of the protective frame is provided with an avoidance groove, the avoidance groove is used to avoid the first protective plate, and the inside of the avoidance groove is provided with a rubber strip.

[0010] As a preferred embodiment of this utility model, the first protective sheet and the second protective sheet are made of a composite material of polycarbonate and glass fiber, and the outer surface of the first protective sheet and the second protective sheet are coated with a nano-silicon wear-resistant coating and the inner surface is coated with an anti-fog coating to ensure long-term clear visibility. The second protective sheet is arc-shaped.

[0011] As a preferred embodiment of this utility model, the feature is that: the inner sidewall of the protective frame is provided with a number of fireproof expansion strips, which expand rapidly when exposed to high temperatures and fill the heat dissipation grooves to prevent flames and smoke from entering the interior of the sign.

[0012] As a preferred embodiment of this utility model, the outer surface of the protective frame is coated with a composite functional coating, which includes a bottom fireproof coating and a surface fluorescent material. The fireproof coating is an intumescent flame-retardant epoxy resin, and the fluorescent material contains nano-sized titanium dioxide particles and glass microspheres, which are used to simultaneously achieve flame-retardant protection and emergency indicator brightness enhancement in a fire environment.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model utilizes a protective shell surface-resistant fire emergency sign with a structure consisting of a protective frame, a U-shaped limiting block, a slot, a first protective plate, a fixing cylinder, a damping spring shock absorber, and a second protective layer. During installation, the sign is embedded into the protective frame and fixed. The power cord is routed through a clearance opening, and the entire structure is fixed to the wall using a mounting bracket. Inside the protective frame, a U-shaped limiting block is embedded into the first protective plate and sealed with rubber. On the other side, a damping spring connects to an arc-shaped second protective plate to absorb impact. The protective plate is made of composite material, combining a nano-silicon wear-resistant coating and an anti-fog coating, balancing transparency and impact resistance. Under normal conditions, the internal temperature is maintained through heat dissipation grooves. In case of fire, fire-resistant expansion strips rapidly expand to seal the groove openings and block fire and smoke. The outer composite coating has both flame-retardant and heat-insulating functions as well as fluorescent brightening functions, ensuring the sign remains visible in an emergency. This invention solves the problems of excessive wall protrusion, large space occupation, increased risk of collisions with the protective structure in emergencies, lack of cushioning design after collision leading to injury, and lack of flame-retardant protection, making the sign prone to failure in a fire.

[0023] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0024] A fire emergency sign with a shatterproof protective shell includes a sign 1. One side of the sign 1 has a mounting plate 101. The sign 1 is surrounded by a protective frame 2. Inside the protective frame 2 is a U-shaped limiting block 201 with an upward-facing slot 202. A first protective plate 203 is located inside the slot 202. On the other side of the U-shaped limiting block 201 away from the sign 1, several fixing cylinders 204 are provided. Damping spring shock absorbers 205 are located inside the fixing cylinders 204. A second protective plate 206 is located at one end of each damping spring shock absorber 205. The top of the protective frame 2 has a clearance opening 102. Several heat dissipation slots 103 are symmetrically arranged on both sides of the protective frame 2. Mounting brackets 104 are located at the four corners of one side of the protective frame 2. During installation, the sign 1 is embedded into the protective frame 2, the power cord of the sign is inserted into the clearance opening, and then the sign 1 is fixed to the protective frame 2 using embedded bolts. The mounting brackets 104 are used to secure the sign. 4. The entire structure is fixed to the wall. The U-shaped limiting block 201 inside the protective frame 2 is embedded into the first protective plate 203 through the avoidance groove. After the rubber strip seals, a sealed structure is formed. In the fixing cylinder 204 on the other side of the U-shaped limiting block 201, the damping spring shock absorber 205 is connected to the arc-shaped second protective plate 206 to absorb external impact. During daily use, the first and second protective plates 203 and 206, made of polycarbonate / glass fiber composite material, take into account both transparency and impact resistance. The nano-silicon coating improves wear resistance, the anti-fog coating ensures clear indication information, and the heat dissipation groove 103 maintains a stable internal temperature. In the event of a fire, the fireproof expansion strip 105 on the inner side of the protective frame 2 expands rapidly when exposed to high temperature to fill the heat dissipation groove 103, blocking the intrusion of flames and smoke. The intumescent flame-retardant epoxy resin in the outer composite functional coating forms a dense carbon layer for heat insulation. The fluorescent material composed of nano-level titanium dioxide particles and glass microspheres enhances the visibility of the sign in the power outage or dense smoke environment, achieving the dual effects of flame-retardant protection and emergency brightening.

[0025] The mounting plate 101 and mounting bracket 104 are respectively provided with mounting holes. After the indicator is embedded into the protective frame through the mounting holes, it is fixed in position by embedded bolts. At the same time, the mounting bracket is fixed to the wall by bolts. The U-shaped limiting block 201 is fixedly connected to the protective frame 2. The top of the protective frame 2 is provided with a clearance groove, which is used to avoid the first protective plate 203. The clearance groove is provided with a rubber strip. The clearance groove is used to assemble the first protective plate 203 and the U-shaped limiting block 201. After assembly, the clearance groove is sealed by the rubber strip. The first protective plate 203 and the second protective plate 206 are made of a composite material of polycarbonate and glass fiber, and the outer surface of the first protective plate 203 and the second protective plate 206 is nano-silicon. The protective frame 2 features a wear-resistant coating and an anti-fog coating on the inner surface to ensure long-term visibility. The second protective sheet 206 is arc-shaped to prevent people from scratching it in emergencies. The first and second protective sheets balance transparency and impact resistance. The inner sidewall of the protective frame 2 is equipped with several fire-resistant expansion strips that expand rapidly when exposed to high temperatures, filling the heat dissipation groove 103 to prevent flames and smoke from entering the sign 1. The outer surface of the protective frame 2 is coated with a composite functional coating, which includes a base fire-retardant coating and a surface fluorescent material. The fire-retardant coating is an intumescent flame-retardant epoxy resin, and the fluorescent material contains nano-sized titanium dioxide particles and glass microspheres to simultaneously achieve flame-retardant protection and emergency indicator brightness enhancement in a fire environment.

[0026] The working process of this utility model is as follows: When using this type of fire emergency sign with a crack-resistant protective shell, firstly, during installation, the sign 1 is embedded inside the protective frame 2, and the power cord of the sign is inserted into the clearance slot. Then, the sign 1 is fixed inside the protective frame 2 using embedded bolts. At the same time, the entire unit is fixed to the wall using the mounting bracket 104. Inside the protective frame 2, the U-shaped limiting block 201 is embedded into the first protective plate 203 through the clearance slot. After the rubber strip seals, a sealed structure is formed. Inside the fixing cylinder 204 on the other side of the U-shaped limiting block 201, the damping spring shock absorber 205 is connected to the arc-shaped second protective plate 206 to absorb external impacts. During daily use... The first and second protective sheets 203 and 206, made of polycarbonate / glass fiber composite material, combine transparency and impact resistance. The nano-silicon coating improves wear resistance, and the anti-fog coating ensures clear indication information. The heat dissipation groove 103 maintains a stable internal temperature. In the event of a fire, the fireproof expansion strip 105 on the inner side of the protective frame 2 expands rapidly at high temperatures to fill the heat dissipation groove 103, blocking the intrusion of flames and smoke. The intumescent flame-retardant epoxy resin in the outer composite functional coating forms a dense carbon layer for heat insulation. The fluorescent material composed of nano-sized titanium dioxide particles and glass microspheres enhances the visibility of the sign in the event of a power outage or in a dense smoke environment, achieving the dual effects of flame-retardant protection and emergency brightening.
