In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".
[0055] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0056] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0057] Reference Figure 1 to Figure 10 , which is an embodiment of the utility model, proposes a fire safety exit light, which is set on the wall, including: a sign 1; a drainage member 3, which is set on the sign 1; a mounting plate 2, which is used to be set on the wall, and the sign 1 is hinged on the mounting plate 2; a driving member 11, one end of which is rotatably set on the mounting plate 2, and the other end of which is rotatably set on the sign 1, and the driving member 11 is used to drive the sign 1 to deflect with the hinge 12 of the sign 1 and the mounting plate 2 as the rotation center. Further, it also includes: a waterproof shell 4, which is covered on the sign 1; a protective plate 5, which is set on the waterproof shell 4.
[0058] In the above scheme, the aim is to overcome the damage of indoor emergency exit lights caused by fire sprinklers in the prior art and the limitations of traditional waterproof measures, and ensure the clear visibility of emergency exit signs and the stable operation of the equipment. Fire emergency exit lights are designed to be installed on walls in crowded areas of buildings.
[0059] As the core component of the emergency exit sign, the sign 1 is made of high-strength, high-temperature-resistant materials with good optical properties, and has eye-catching identification symbols such as "Emergency Exit" and arrows pointing to the direction of the emergency exit printed or embedded on the surface. In order to improve visibility and recognition under emergency conditions, the sign 1 uses fluorescent or self-luminous materials to ensure that it can remain clearly visible when normal lighting is interrupted.
[0060] The drainage member 3 can quickly guide and discharge the water sprayed on the sign 1 to prevent the accumulation of water from damaging the electronic components inside the sign 1. The design of the drainage member 3 should ensure that it does not affect the visual effect of the sign 1 and has good waterproof sealing performance.
[0061] The mounting plate 2 is fixed on the wall to carry and support the entire fire safety exit light. The mounting plate 2 is made of fireproof and corrosion-resistant metal or composite material, and a mounting hole 5021 or a snap-on structure is provided on the back thereof to facilitate a firm connection with the wall. A hinge device or other mechanical connection mechanism is provided on the mounting plate 2, so that the sign 1 can be deflected at an angle with the hinge 12 as the center. Under the action of the driving member 11, the sign 1 can deflect smoothly and reliably. For example, when the sign 1 is installed at a high place indoors, the sign 1 will be deflected toward the ground side under the action of the driving member 11, which is not only convenient for personnel to observe, but also convenient for maximizing the effect of the drainage member 3.
[0062] The moving part is activated when receiving a signal from the fire protection system or the sensor detects a fire sprinkler, and drives the sign 1 to deflect at a preset angle with the hinge 12 as the rotation center. The deflection design is intended to enable the sign 1 to automatically adjust its posture when spraying water, avoiding direct water spray on the sign 1, while maintaining the effective display of the indication information to the escapee. The driving part 11 should have a rapid response capability and an overload protection mechanism to ensure stable and accurate execution of actions in emergency situations. Under normal conditions, the sign 1 of the fire safety exit light remains upright, clearly indicating the location of the safety exit to personnel. Once a fire occurs and the fire sprinkler system is activated, the driving part 11 immediately drives the sign 1 to deflect after sensing the water spray signal, and uses the drainage part 3 to effectively drain the sprayed water to avoid damage to the sign 1, while ensuring that the indication information is still easy to observe at the deflected angle, providing effective guidance for personnel to quickly identify the escape route. Through the above structural design and functional integration, the fire safety exit light of this embodiment successfully solves the problem that the safety exit lights in the prior art are easily damaged by fire water spray, as well as the limitations of traditional waterproof measures, and improves the reliability of indications during emergency evacuation, providing strong support for the safe evacuation of personnel and rescue operations. In summary, the fire safety exit light provided by this embodiment has good waterproof performance, automatic deflection function, and high-visibility indication in emergency conditions, which meets the needs of the field for new fire safety exit lights and has significant technical progress and practical value.
[0063] Furthermore, the protective plate 5 has a receiving groove 5012, and the guide member 3 includes: a first guide plate 301, which is arranged on the back of the sign 1, and the first guide plate 301 has a guide groove 3011; a second guide plate 302, which is slidably arranged in the receiving groove 5012, and after the sign 1 is deflected, the second guide plate 302 extends out of or cancels extending out of the receiving groove 5012.
[0064] In the above solution, the protective plate 5 is used as an additional waterproof barrier. The protective plate 5 is tightly fitted to the back of the sign 1. Its material should match the sign 1 and have good heat resistance, corrosion resistance and waterproof performance. The protective plate 5 is specially designed with a receiving groove 5012. The shape and size of the receiving groove 5012 are adapted to the second guide plate 302, and are used for hidden storage or guiding the sliding of the second guide plate 302.
[0065] The first guide plate 301 is arranged on the back of the sign 1. The first guide plate 301 is made of a material that is coordinated with the material of the sign 1, and has continuous or spaced guide grooves 3011 on its surface. The guide grooves 3011 are slightly inclined, and their design purpose is to quickly guide the water that falls on the back of the sign 1 and the protective plate 5 to flow along the groove to a designated position to avoid water accumulation. A good sealing connection should be maintained between the first guide plate 301 and the sign 1 to prevent water penetration.
[0066] The second guide plate 302 is slidably disposed in the receiving groove 5012 of the protective plate 5, and can be automatically extended or canceled according to the deflection state of the sign 1. The second guide plate 302 is also made of heat-resistant, corrosion-resistant and waterproof materials, and a guide groove 3011 similar to the first guide plate 301 can be provided on its surface to enhance the drainage effect. A smooth slide rail or ball structure should be provided between the second guide plate 302 and the inner wall of the receiving groove 5012 to ensure that the second guide plate 302 can be smoothly and quickly extended or retracted under the action of the driving member 11. Under normal conditions, the second guide plate 302 is hidden in the receiving groove 5012 of the protective plate 5 and does not interfere with the normal display of the sign 1. When a fire occurs and the fire sprinkler system is activated, the driving member 11 drives the sign 1 to deflect at a preset angle with the hinge 12 as the rotation center. At this time, the second guide plate 302 automatically extends out of the receiving groove 5012 under the linkage action of the driving member 11 or under the influence of gravity, and forms a multi-directional waterproof guide system together with the first guide plate 301, effectively guiding the water sprayed on each side of the sign 1 to be quickly discharged, and minimizing the influence of water on the sign 1 and the internal electronic components. After the deflection angle of the sign 1 is restored, the second guide plate 302 slides back into the receiving groove 5012 under the reverse force of the driving member 11 or the action of its own elastic element, and returns to the hidden state, maintaining the overall beauty and space utilization of the fire safety exit lamp. Through the above improvements, the fire safety exit lamp of this embodiment not only has waterproof, automatic deflection and high visibility indication functions, but also constructs a more complete three-dimensional waterproof system through the first guide plate 301 and the slidable second guide plate 302, further improving the protection ability of the equipment in a water spray environment, ensuring that the safety exit indication is continuously clear and visible, and enhancing the indication reliability during emergency evacuation.
[0067] Further, the protective plate 5 has a card slot 5011 near the back of the sign 1, and the first deflector 301 is inserted into the card slot 5011.
[0068] In the above solution, the protective plate 5 is in a "Ji" shape, and a card slot 5011 structure is added near the back of the sign 1 on the protective plate 5. The design of the card slot 5011 should be precisely matched with the shape and size of the first deflector 301 to ensure a firm insertion between the two. The depth, width, and edge treatment of the card slot 5011 should be conducive to the smooth insertion and stable fixation of the first deflector 301, while avoiding affecting the display surface of the sign 1.
[0069] The first deflector 301: Instead of being directly fixed to the back of the sign 1, it is inserted into the card slot 5011 of the protective plate 5. The edge of the first deflector 301 cooperates with the edge of the card slot 5011 to form a tight insertion relationship, ensuring its stable fixation in any state (including when the sign 1 deflects), and is used to enhance the waterproof drainage effect. In the normal state, the first deflector 301 is fixed to the protective plate 5 through the card slot 5011 and is closely attached to the back of the sign 1 without interfering with the normal display of the sign 1. When a fire occurs and the fire sprinkler system is activated, the driving member 11 drives the sign 1 to deflect by a preset angle with the hinge portion 12 as the rotation center, and the first deflector 301 deflects synchronously with the sign 1, effectively guiding the water falling on the back of the sign 1 and the protective plate 5 along the diversion groove 3011 to a designated position, avoiding water accumulation, and protecting the sign 1 and the internal electronic components from damage. The connection method between the first deflector 301 and the protective plate 5 is simplified, using direct insertion instead of fixing to the back of the sign 1, reducing the manufacturing cost, improving the assembly efficiency, and at the same time ensuring the stable follow-up of the first deflector 301 during the deflection process, maintaining the effectiveness of the waterproof diversion system. In addition, this structural design is more conducive to the maintenance and replacement of the first deflector 301, improving the service life of the equipment and user-friendliness.
[0070] Further, it further includes: an arc-shaped baffle 6, which is arranged on the first deflector 301 and is located above the sign 1, and the arc-shaped baffle 6 is used to block the gap between the first deflector 301 and the back plate of the sign 1.
[0071] In the above scheme, the arc baffle 6 is made of a heat-resistant, corrosion-resistant and waterproof material coordinated with the first guide plate 301 and the protective plate 5, and its shape is designed to be arc-shaped so as to better cover and shield the gap between the first guide plate 301 and the back plate of the sign 1. The connection between the arc baffle 6 and the first guide plate 301 and the back plate of the sign 1 should maintain good sealing to prevent moisture penetration. Under normal conditions, the arc baffle 6 is tightly attached to the upper back of the sign 1, shielding the gap between the first guide plate 301 and the back plate of the sign 1, forming an additional waterproof barrier. When a fire occurs and the fire sprinkler system is activated, the drive member 11 drives the sign 1 to deflect at a preset angle with the hinge 12 as the rotation center. Since the first guide plate 301 and the protective plate 5 are plugged together, the first guide plate 301 deflects synchronously with the sign 1, and the arc baffle 6 moves accordingly, always maintaining effective shielding of the gap between the first guide plate 301 and the back plate of the sign 1, preventing moisture from penetrating from the gap, and further enhancing the waterproof effect. After the deflection angle of the sign 1 is restored, the arc baffle 6 returns to the initial position driven by the first guide plate 301, and continues to shield the gap between the first guide plate 301 and the back plate of the sign 1, maintaining the overall waterproof performance of the fire safety exit light. The arc baffle 6 effectively shields the gap between the first guide plate 301 and the back plate of the sign 1, forming a more rigorous waterproof system, greatly reducing the possibility of moisture penetrating from the gap, further improving the protection capability of the equipment in a water spraying environment, ensuring that the safety exit indication is continuously clear and visible, and enhancing the indication reliability during emergency evacuation.
[0072] Furthermore, the protective plate 5 includes: a plate body 501, which is arranged on the waterproof shell 4; an ear plate 502, which is arranged on the plate body 501, and the ear plate 502 has a mounting hole 5021; a fastener 503, which is arranged in the mounting hole 5021, and the sign 1 is arranged on the driving member 11 through the fastener 503; the waterproof shell 4 has a through groove 401, and the through groove 401 is located on the front end surface of the sign 1, and the graphic information of the sign 1 is displayed to the outside through the through groove 401.
[0073] In the above scheme, the waterproof housing 4 is used to cover the sign 1. The shape of the waterproof housing 4 matches the sign 1, and the sign 1 is tightly wrapped around to prevent water from being directly sprayed from around the sign 1. The front face of the waterproof housing 4 is provided with a through groove 401 corresponding to the graphic information of the sign 1. The graphic information of the sign 1 is clearly displayed to the outside through the through groove 401, and the escapee can quickly identify the location and direction of the safety exit.
[0074] The ear plates 502 are arranged on both sides or four corners of the plate body 501, and are provided with mounting holes 5021 matching the driving member 11. The material of the ear plates 502 should be consistent with that of the plate body 501, and have sufficient strength and toughness to withstand the torque applied by the driving member 11, and ensure the stability of the sign 1 during the deflection process. The shape and position of the ear plates 502 should be convenient for docking with the connecting piece of the driving member 11.
[0075] Installation process. The fastener 503 is arranged in the mounting hole 5021, and is used to firmly connect the plate body 501 (through the ear plate 502) and the driving member 11. The fastener 503 can be selected from mechanical connectors such as bolts, screws, rivets, etc., and its specifications should match the mounting hole 5021 and the driver 11 connector to ensure the stability and reliability of the connection. During installation, the ear plate 502 of the plate body 501 is tightly fixed to the driving member 11 by the fastener 503, so that the sign 1 and the driving member 11 form a stable transmission relationship. The sign 1 is directly set on the driving member 11 by bolts to ensure that it can accurately and smoothly deflect under the action of the driving member 11. Secondly, the seal between the waterproof shell 4 and the sign 1 should be good to prevent moisture from penetrating between the two. Under normal conditions, the waterproof shell 4 protects the sign 1 from environmental factors such as dust and moisture, and clearly displays the indication information through the through groove 401. When a fire occurs and the fire sprinkler system is activated, the driving member 11 drives the sign 1 to deflect at a preset angle with the hinge 12 as the rotation center, and the waterproof shell 4, the plate body 501 and the ear plate 502 deflect together with the sign 1, maintaining all-round protection for the sign 1, while ensuring that the indication information is continuously and clearly displayed through the through slot 401.
[0076] Furthermore, the driving member 11 includes: a telescopic rod 1104, one end of which is hinged to the mounting plate 2, and the other end is hinged to the ear plate 502; a support 1101, which is arranged on the ear plate 502, and one end of the mounting hole 5021 through which the fastener 503 passes is arranged on the support 1101; a first connecting rod 1102, one end of which is hinged to the support 1101; a second connecting rod 1103, one end of which is hinged to the mounting plate, and the other end of which is hinged to the end of the first connecting rod 1102 away from the support 1101.
[0077] In the above scheme, the telescopic rod 1104 is used as a driving source, one end of which is hingedly arranged on the mounting plate 2, and the other end of which is hingedly arranged on the ear plate 502. The telescopic rod 1104 can be a driving device with a telescopic function such as an electric push rod or a hydraulic rod, and its working stroke should be sufficient to drive the sign 1 to complete the preset deflection angle. The telescopic rod 1104 should have functions such as fast response, smooth operation and overload protection to ensure reliable operation in emergency situations.
[0078] The support 1101 is firmly fixed to the ear plate 502 by fasteners 503, one end of the first connecting rod 1102 is fixed to the support 1101 by hinged connection, and the other end is connected to the second connecting rod 1103. The length and hinge point position of the first connecting rod 1102 should be reasonably designed according to factors such as the stroke of the telescopic rod 1104, the deflection angle of the sign 1, and the installation space, so as to ensure that during the telescopic process of the telescopic rod 1104, the first connecting rod 1102 can accurately transmit power through the hinged connection with the second connecting rod 1103 to drive the sign 1 to deflect. One end of the second connecting rod 1103 is fixed to the mounting plate by hinged connection, and the other end is hinged to the end of the first connecting rod 1102 away from the support 1101. The length and hinge point position of the second connecting rod 1103 should be coordinated with the first connecting rod 1102 to ensure that the hinged connection between the two can achieve a stable deflection of the sign 1.
[0079] Furthermore, it also includes: a controller, which is arranged in the signboard 1 and is electrically connected to the telescopic rod 1104; a humidity sensor 7, which is arranged on the signboard 1 or the mounting plate 2 and is electrically connected to the controller. After the controller receives the signal from the humidity sensor 7, the controller controls the telescopic rod 1104 to work.
[0080] In the above scheme, the controller is arranged inside the sign 1 and is electrically connected to the telescopic rod 1104. The controller adopts a microprocessor, a single-chip microcomputer or other embedded control unit, which is responsible for receiving external signals, processing logical judgments and controlling the movement of the telescopic rod 1104. The controller should have the characteristics of strong anti-interference ability, stable operation, and fast response speed, so as to ensure that the telescopic rod 1104 can be accurately and timely controlled in an emergency. Humidity sensor 7: It is arranged on the sign 1 or the mounting plate 2 and is used to monitor the humidity changes in the surrounding environment in real time. The humidity sensor 7 should have the characteristics of high sensitivity, fast response, and high precision, and can detect the significant increase in humidity in time at the beginning of the fire and after the sprinkler system is started, and send the humidity signal to the controller. The humidity sensor 7 should be closely combined with the sign 1 or the mounting plate 2 to ensure that it can still work normally in harsh environments. When the humidity sensor 7 detects that the humidity exceeds the set threshold, it indicates that there may be a fire or the sprinkler system has been started, and the humidity sensor 7 sends this signal to the controller. After receiving the signal from the humidity sensor 7, the controller determines whether the telescopic rod 1104 needs to be started according to the preset program logic. If the result of the determination is that it needs to be started, the controller immediately sends a command to the telescopic rod 1104 to control it to start working, and drives the sign 1 to deflect at a preset angle with the hinged portion 12 as the rotation center.
[0081] Furthermore, the back of the sign 1 has a cable trough 101 , and also includes: a cable connector 9 that passes through the protective plate 5 and is arranged on the sign 1 ; an electric wire 8 that extends out of the sign 1 through the cable connector 9 , and a portion of the electric wire 8 outside the sign 1 is snapped into the cable trough 101 .
[0082] In the above scheme, a cable trough 101 is added to the back of the sign 1. The cable trough 101 is set along the back edge of the sign 1 or at an appropriate position inside to regularly accommodate the wires 8 to prevent the wires 8 from being scattered, worn or damp. The material of the cable trough 101 should be consistent with the main body of the sign 1, and have good insulation and waterproof capabilities. The cable connector 9 is set on the protective plate 5 and is connected to the internal circuit of the sign 1. The cable connector 9 should be a waterproof connector that meets the electrical safety standards to ensure a reliable connection between the wire 8 and the internal circuit of the sign 1. The cable connector 9 should be set at a position that is easy to operate on the protective plate 5 to facilitate the access and removal of the wire 8. The wire 8 extends out of the sign 1 through the cable connector 9, and the part outside the sign 1 (i.e., the part from the cable connector 9 to the power supply or controller) should be snapped into the cable trough 101. The snapping of the wire 8 and the cable trough 101 should be tight and firm to prevent the wire 8 from loosening or being damaged during the deflection of the sign 1. Under normal working conditions, the wire 8 is connected to the internal circuit of the sign 1 through the cable connector 9 to provide power supply for the sign 1. The wire 8 extending outside the sign 1 is neatly snapped into the cable trough 101, which not only ensures the safe and orderly arrangement of the wire 8, but also avoids the influence of the wire 8 on the deflection of the sign 1. When a fire occurs or the sprinkler system is activated, the sign 1 deflects under the drive of the telescopic rod 1104, and the wire 8 moves synchronously with the sign 1 under the constraint of the cable trough 101, maintaining a good connection with the sign 1, and ensuring the normal operation of the equipment in an emergency state.
[0083] Furthermore, it also includes: a sealing strip 10, which is arranged in the gap between the back of the sign 1 and the protective plate 5.
[0084] In the above scheme, the sealing strip 10 is arranged in the gap between the back of the sign 1 and the protective plate 5. The sealing strip 10 is made of an elastic material with excellent waterproof, heat-resistant and aging-resistant properties, such as silicone rubber, EPDM (ethylene propylene diene copolymer) or chloroprene rubber, etc. Its cross-sectional shape can be designed to be T-shaped, D-shaped or O-shaped, etc., to adapt to different installation gaps and provide better sealing effects. The length of the sealing strip 10 should cover the edge where the back of the sign 1 contacts the protective plate 5 to ensure the continuity and integrity of the seal. During installation, the sealing strip 10 is tightly pressed into the gap between the back of the sign 1 and the protective plate 5 to form an effective waterproof barrier. The elastic force of the sealing strip 10 enables it to fit closely to the surfaces of the two components, and maintain a good sealing effect even when the sign 1 is deflected, preventing moisture, dust and other harmful substances from invading the internal circuit and mechanical structure, thereby protecting the electrical safety of the sign 1 and extending the service life of the equipment.
