Description

Technical Field

[0001] This utility model relates to the field of fire safety sign light technology, and in particular to a fire safety sign that is easy to assemble and disassemble. Background Technology

[0002] Fire safety signs, as an important component of building fire safety systems, are widely used in various public places, such as shopping malls, office buildings, and residential areas. Their main function is to provide clear and conspicuous directional signs in emergencies such as fires, guiding people to evacuate quickly and ensuring their safety. With increasingly stringent building codes and heightened public safety awareness, the reliability, visibility, and ease of maintenance of fire safety signs have become critical requirements.

[0003] In the past, the industry commonly used bolt fixing for the installation of fire hazard signs. Installers first needed to drill holes in the sign and then use bolts to secure it firmly to the frame. Afterward, the frame with the sign was fixed to a suitable location on the wall. This installation method had been proven through long-term practice and could ensure the stability of the fire hazard signs to a certain extent. However, this installation process involved multiple steps, was time-consuming, and had low efficiency. Furthermore, regular maintenance or changes to the signage also required a complex disassembly process. Utility Model Content

[0004] To improve the ease of replacing fire safety signs, make the installation process more convenient and efficient, and shorten the operation time, this application provides a fire safety sign that is easy to install and remove.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A fire safety light sign that is easy to assemble and disassemble includes a light guide plate, an indicator sign, and a housing. The indicator sign is attached to one side of the light guide plate, and the bottom of the housing has a slot. The light guide plate is inserted into the slot and detachably connected to the bottom of the housing.

[0007] The top of the compartment is connected to a top cover, and a top plate is provided on the upper end of the top cover. Square through holes are provided at both ends of the top plate. The top plate extends downward along the side of the square through holes near the middle of the top plate and bends to form a movable buckle. The movable buckle includes an extension part and a bending part. The upper edge of the light guide plate is provided with a mating groove that cooperates with the movable buckle. The top surface of the bending part and the top surface of the mating groove are in contact with each other during assembly.

[0008] By adopting the above-mentioned device, the fire-fighting light sign uses a movable clip and a matching groove for engagement. Compared to the existing bolt fixing, the light guide plate can be easily inserted into the slot at the bottom of the housing and achieve a detachable connection. During installation, simply insert the light guide plate into the slot, and the movable clip will engage with the matching groove. The operation is simple and quick, improving installation efficiency and meeting the building code requirements for the maintainability of fire-fighting light signs.

[0009] Preferably, the upper edge of the light guide plate is provided with a guide bevel that connects with the opening end of the mating groove, and the bottom of the movable buckle is provided with a curved chamfer that matches the guide bevel.

[0010] By using the above-mentioned device, the combination of the guide bevel and the chamfered surface makes it easier for the movable buckle to be inserted into the mating groove, making the installation of the light guide plate more precise and faster.

[0011] Preferably, the width of the movable buckle is greater than the width of the mating groove opening, and the length of the movable buckle is greater than the width of the slot.

[0012] By adopting the above-mentioned device, the disengagement of the movable buckle and the mating groove is reduced, thereby improving the stability of the light guide plate installation.

[0013] Preferably, a light source board is provided inside the compartment, and the bottom plate of the compartment extends upward along the perimeter of the slot to form a vertical plate. The light source board is installed on the top of the vertical plate, and multiple LED beads are provided on the side of the light source board facing the light guide plate.

[0014] By using the above-mentioned device, the light source board has multiple LEDs pointing towards the light guide plate to provide illumination for the fire safety signs, making the signs clearer and more eye-catching in emergency situations and improving their visibility.

[0015] Preferably, a notch is provided at the upper edge of the vertical plate, and the notch corresponds to the movable buckle. When the compartment box is assembled with the top cover, the movable buckle extends into the notch.

[0016] By using the above-mentioned device, the movable buckle extends into the notch, making it easy to mate with the mating groove during installation.

[0017] Preferably, a reinforcing rib is provided between one side of the extension and the bottom of the top plate.

[0018] By employing the aforementioned device, reinforcing ribs are installed between one side of the extension and the bottom of the top plate, enhancing the structural strength of the movable latch. When disassembling the light guide plate, tools are used to press the movable latch to deform it and disengage it from the mating groove. However, due to the difficulty in precisely controlling the force, excessive pressure can easily cause the movable latch to deform beyond its recovery capacity and become damaged without reinforcing ribs. The reinforcing ribs improve the movable latch's resistance to deformation, preventing damage due to excessive pressure, extending its service life, and ensuring the normal installation, removal, and use of the fire safety light sign.

[0019] Preferably, the light source plate is provided with an anti-collision block, and the upper edge of the light guide plate is provided with an abutment groove, and the anti-collision block corresponds to the abutment groove.

[0020] Preferably, the height of the anti-collision block is greater than the depth of the abutment groove.

[0021] By using the above-mentioned device, when installing the light guide plate, a certain amount of force is required to insert the light guide plate into the slot. At this time, because the light source plate is equipped with anti-collision blocks that correspond to the abutment groove on the upper edge of the light guide plate, the collision between the light guide plate and the lamp beads can be effectively avoided, thereby reducing the damage to the lamp beads, improving the service life and reliability of the light source components in the fire-fighting light sign, and reducing the maintenance cost and replacement frequency caused by lamp bead damage.

[0022] This application has the following beneficial effects:

[0023] 1. In this application, the fire-fighting light sign adopts a method of engaging a movable clip with a mating groove. Compared with the existing bolt fixing, the light guide plate can be easily inserted into the slot at the bottom of the compartment and achieve a detachable connection. During installation, simply insert the light guide plate into the slot, and the movable clip will engage with the mating groove. The operation is simple and quick, improving installation efficiency and meeting the building code requirements for the maintainability of fire-fighting light signs.

[0024] 2. In this application, the combination of the guide bevel and the curved chamfer makes it easier for the movable buckle to be inserted into the mating groove, making the installation of the light guide plate more precise and faster. Attached Figure Description

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0034] A type of fire safety light sign that is easy to install and remove, such as Figure 1 As shown, the system includes a light guide plate 1, a sign 2, and a storage box 3. The storage box 3 is integrally molded from plastic material, with a long slot 31 at the bottom. The light guide plate 1 is inserted into the slot 31 and detachably connected to the bottom of the storage box 3, making the connection between the light guide plate 1 and the storage box 3 convenient and stable, facilitating subsequent assembly and disassembly. The sign 2 is attached to one side of the light guide plate 1, using either adhesive or electrostatic adsorption. The sign 2 is a thin plastic sheet printed with evacuation arrows, text, and other markings. In this embodiment, the light guide plate 1 is made of acrylic, with a regular rectangular shape, a smooth surface, and good light guiding performance. The sign 2, with the help of the light guide plate 1, can better display directional information, achieving the function of guiding personnel evacuation in emergencies.

[0035] like Figure 1-3 As shown, the top of the storage box 3 is open, and a top cover 4 is bolted to the top of the storage box 3. When the storage box 3 and the top cover 4 are assembled, they form a lamp box with an internal cavity. A top plate 41 is provided on the upper end of the top cover 4. Two square through holes 411 are respectively opened at both ends of the top plate 41. The top plate 41 extends downward along the side of the square through holes 411 near the middle of the top plate 41 and bends to form a movable buckle 42. In this embodiment, the top cover 4, the top plate 41 and the movable buckle 42 are integrally molded from plastic material. The movable buckle 42 includes an extension 421 and a bending part 422. The extension 421 is perpendicular to the top plate 41. The bending part 422 is the end bending part of the movable buckle 42. The top surface of the bending part 422 and the inner top surface of the mating groove 11 provided on the upper edge of the light guide plate 1 come into contact with each other during assembly, and both are horizontal surfaces to form an interlocking anti-detachment structure.

[0036] In addition, in order to further reduce the accidental detachment of the light guide plate 1, the width of the movable buckle 42 is greater than the width of the opening of the mating groove 11, and the length of the movable buckle 42 is greater than the width of the slot 31. During assembly, the movable buckle 42 can better engage with the mating groove 11 to lock the light guide plate 1 and prevent the light guide plate 1 from coming out of the slot 31.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, the movable buckle 42 has a certain degree of elasticity and toughness. When the light guide plate 1 is inserted into the slot 31, the movable buckle 42 will undergo a certain elastic deformation and then lock into the mating groove 11, achieving a firm connection between the light guide plate 1 and the housing 3. To make the insertion process smoother, the upper edge of the light guide plate 1 is provided with a guide bevel 12 that connects with the opening end of the mating groove 11, and the bottom of the movable buckle 42 is provided with a curved chamfer 422a that matches the guide bevel 12. The guide bevel 12 guides the movable buckle 42 to slide smoothly into the mating groove 11, making the installation of the light guide plate 1 more precise and faster.

[0038] like Figure 1-3 As shown, when it is necessary to disassemble the light guide plate 1, a tool (such as a screwdriver) is used to press the movable buckle 42 through the square through hole 411 to disengage the movable buckle 42 from the mating groove 11, thus completing the disassembly of the light guide plate 1, which is convenient and quick. Since it is difficult to precisely control the pressure of pressing the movable buckle 42, if the pressure is too great, the movable buckle 42 may be excessively deformed and break. Therefore, a reinforcing rib 43 is provided between one side of the extension 421 and the bottom of the top plate 41. The reinforcing rib 43 is a triangular plate. The function of the reinforcing rib 43 is to enhance the strength of the movable buckle 42, improve its resistance to deformation, and prevent the movable buckle 42 from being damaged due to excessive deformation during use, thereby ensuring the reliable fit between the movable buckle 42 and the mating groove 11, and ensuring the normal disassembly, assembly, and use of the fire light sign.

[0039] like Figure 1 , Figure 5 and Figure 6 As shown, a light source plate 5 is installed inside the compartment 3, providing illumination for the light guide plate 1. The light source plate 5 is mounted on top of the vertical plate 32 inside the compartment 3. The vertical plate 32 is formed by extending upwards from the bottom plate of the compartment 3 along the perimeter of the slot 31, and its function is to provide mounting support for the light source plate 5. A notch 321 is provided on the upper edge of the vertical plate 32, and the notch 321 corresponds to the movable buckle 42. When the compartment 3 is assembled with the top cover 4, the movable buckle 42 extends into the notch 321. The notch 321 is designed to prevent the movable buckle 42 from interfering with the vertical plate 32, ensuring that the movable buckle 42 can function properly.

[0040] Multiple LED beads 51 are installed on the light source board 5. In this embodiment, LED beads 51 are selected, which have the advantages of energy saving, high brightness and long life. The multiple LED beads 51 are evenly arranged on the side of the light source board 5 facing the light guide plate 1 to ensure that the light guide plate 1 receives uniform light and makes the information on the sign 2 more clearly visible.

[0041] In addition, anti-collision blocks 52 are also installed on the light source plate 5. In this embodiment, there are two anti-collision blocks 52, which are located between two adjacent lamp beads 51. The upper edge of the light guide plate 1 is provided with an abutment groove 13 that cooperates with the anti-collision block 52. The height of the anti-collision block 52 is greater than the depth of the abutment groove 13. When the light guide plate 1 is inserted into the slot 31, the anti-collision block 52 can buffer the impact force between the light guide plate 1 and the light source plate 5, so that there is a certain distance between the light guide plate 1 and the light source plate 5, so as to avoid the collision between the light guide plate 1 and the lamp beads 51 on the light source plate 5, and play a protective role.

[0042] Working Principle: This application, through the engagement of the movable buckle 42 and the mating groove 11, and the setting of the slot 31, makes the installation and disassembly of fire-fighting light signs simpler and faster, avoiding the cumbersome traditional bolt fixing method. Compared with existing technologies, this structure greatly improves installation and maintenance efficiency and reduces maintenance costs. At the same time, the inclusion of components such as the light source plate 5 and the anti-collision block 52 ensures the lighting effect and service life of the fire-fighting light signs, improves their reliability and practicality, and meets the higher requirements of building codes and the public for fire safety.

[0043] 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.
