Description

Technical Field

[0001] This utility model relates to the field of fire safety sign lights, specifically to a double-sided fire emergency evacuation sign light. Background Technology

[0002] Fire emergency evacuation signs are key facilities for guiding people to evacuate safely in emergency situations such as building fires. The ease of installation, the reliability of connection, and the stability of long-term use are of paramount importance.

[0003] In existing technologies, such as the double-sided fire emergency evacuation sign light disclosed in CN223257869U, although there have been improvements in terms of structural thinness, their installation still largely relies on multiple screws tightened at different angles. This installation method is not only inefficient, but also makes it difficult to ensure consistent tightening torque. Too loose a screw can lead to loosening and detachment under long-term vibration, posing a safety hazard; too tight a screw can damage components. Furthermore, the sealing of the housing joints of such products often uses static gaskets, resulting in a passive sealing effect. This requires high installation precision and is prone to causing internal circuit boards to become damp and dusty due to poor sealing, leading to short circuits, light decay, or even failure, seriously affecting the reliability of fire safety. Therefore, there is an urgent need for a double-sided fire emergency evacuation sign light that is easy to install, reliably locked, and has excellent sealing performance. Utility Model Content

[0004] This utility model proposes a double-sided fire emergency evacuation sign light, which solves the problems existing in the current technology.

[0005] The technical solution of this utility model is as follows: A double-sided fire emergency evacuation sign light includes a top cover and a bottom cover of a mounting frame. The outer walls of the top cover are provided with slots, and the inner walls of the bottom cover are provided with clearance grooves that slide and engage with the slots. A sign display sheet is installed on the inner sides of the top cover and the bottom cover, respectively. A microcontroller circuit board is fixed on the inner side of the bottom cover, and a light guide plate is provided on the inner side above the microcontroller circuit board. A positioning block of the bottom cover holds the light guide plate in place.

[0006] Preferably, the inner wall of the lower cover of the mounting frame is provided with a clearance groove, and the outer wall grooves of the upper cover of the mounting frame are slidably disposed in the clearance groove.

[0007] Preferably, an ear seat is fixedly connected to the outer side of the lower cover of the mounting frame.

[0008] Preferably, the inner wall of the lower cover of the mounting frame is further fixed with a positioning post, which cooperates with the top of the upper cover of the mounting frame.

[0009] The beneficial effects of this utility model are as follows:

[0010] Installation efficiency is significantly improved: Utilizing a sliding plug-in and self-locking structure with a "slot-relief slot," true quick-plug installation is achieved. Installers do not need any tools; simply align the top and bottom covers of the mounting frame and gently push. A "click" sound indicates the slot has engaged with the relief slot, completing the installation and locking process. Compared to traditional screw fastening methods, installation time is drastically reduced, making it particularly suitable for large-scale installations requiring hundreds or thousands of units, effectively lowering labor costs.

[0011] Reliable connection and strong vibration resistance: The positioning post and the top cover form a stable engagement, providing a reliable mechanical safety barrier against detachment. This structure can effectively resist the impact of daily building vibrations or sudden events, ensuring that the indicator lights will not fail due to loosening in emergencies, thus guaranteeing the continuity and reliability of evacuation guidance.

[0012] Extremely convenient maintenance: When it is necessary to replace the light source (such as the LED light panel) or perform internal cleaning, maintenance personnel do not need to find and unscrew multiple screws. Simply pull the cover outward by hand to overcome the rebound force and disengage the slot from the positioning groove, easily separating the upper and lower covers for maintenance. After maintenance, simply align and push it back in for quick reset, greatly reducing maintenance difficulty and time costs, and avoiding maintenance oversights caused by inconvenience.

[0013] Compact structure and comprehensive functions: The rational layout of the light guide plate and double-sided indicator display ensures that the indicator patterns are clear and conspicuous in both directions, without halo interference. The ear-mount design facilitates on-site installation and fixation, while the positioning posts ensure vertical alignment when the upper and lower covers are closed. The entire design achieves the core function of quick assembly and disassembly while fully meeting all the basic functional requirements of fire emergency indicator lights.

[0021] like Figures 1 to 5 As shown, this utility model provides a double-sided fire emergency evacuation sign light, including a top cover 2 and a bottom cover 1 of a mounting frame. The outer walls of the top cover 2 are provided with slots 11, and the inner wall of the bottom cover 1 is provided with clearance grooves 221 that slide and engage with the slots 11. A sign display piece 14 and a sign display piece 25 are respectively installed on the inner sides of the top cover 2 and the bottom cover 1. A microcontroller circuit board 6 is fixed to the inner side of the bottom cover 1, and a light guide plate 3 is provided above the microcontroller circuit board 6 on this inner side.

[0022] The inner wall of the lower cover 1 of the mounting frame is provided with a positioning block 22, and the light guide plate is installed inside it. An ear seat 23 is fixedly connected to the outer side of the lower cover 1 of the mounting frame. A positioning post 21 is also fixed to the inner wall of the lower cover 1 of the mounting frame, and the positioning post 21 cooperates with the top of the upper cover 2 of the mounting frame.

[0023] During installation, first, place the indicator display piece 25, light guide plate 3, and microcontroller circuit board 6 sequentially on the inside of the lower cover 1 of the mounting frame. Then, insert the indicator display piece 14 into the inside of the upper cover 2 of the mounting frame. Next, lift the upper cover 2 of the mounting frame and align it with the lower cover 1, applying pressure to push it. During this process, the inclined surface of the slot 11 contacts the edge of the relief groove 221 and contracts inward, compressing the relief groove 221 behind it. When the upper cover 2 of the mounting frame is fully pushed into place, the relief groove releases its elasticity, quickly pushing the slot 11 into the relief groove 221, producing a "click" sound, forming a mechanical self-locking mechanism. Simultaneously, the positioning post 21 abuts against the top of the upper cover 2 of the mounting frame, providing auxiliary positioning and support to ensure a tight seal. The mounting frame is fixed to a predetermined position on the ceiling or other parallel-to-the-ground surface by passing through or securing the ear seat 23 on the outer side of the cover 1 below the mounting frame with a pre-installed chain or rod. The power line is then connected to the microcontroller circuit board 6, thus completing the quick installation.

[0024] When powered on, the microcontroller circuit board 6 controls the LED beads to emit light. The light is evenly diffused through the light guide plate 3 and penetrates the sign display sheets 1 and 2, simultaneously forming clear and bright evacuation indicator patterns on both sides of the sign light. The inner wall of the cover effectively prevents light leakage backward, ensuring that the light effect is concentrated forward and improving the purity of the display.

[0025] When maintenance is required, the maintenance personnel only need to pull the top cover 2 of the mounting frame outward by hand. The applied pulling force will force the slot 11 to open outward and disengage from the relief slot 221, thereby releasing the self-locking, easily separating the upper and lower covers, exposing the internal components for replacement or cleaning. The entire disassembly process does not require any tools and is extremely convenient.

[0026] In summary, this utility model perfectly solves the pain point of cumbersome installation and maintenance of traditional fire warning lights through a clever pure mechanical self-locking structure. While ensuring connection reliability and indication function, it greatly improves construction and maintenance efficiency.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
