Description

Technical Field

[0001] This invention belongs to the field of fire emergency light installation technology, specifically a quick-install base structure for a fire emergency light with magnetic fixation. Background Technology

[0002] Fire emergency lights are fire-fighting equipment that provide illumination and evacuation guidance in emergencies such as fires. They feature automatic start-up upon power failure, low power consumption, and long lifespan, with an emergency response time typically not less than 90 minutes. They use LED light sources and are powered by batteries or centralized power supplies. Installation methods include wall-mounted, ceiling-mounted, and recessed installations, and they are widely installed in key locations such as evacuation routes and safety exits. Their applications cover public places such as factories, hotels, schools, hospitals, shopping malls, stations, and airports, as well as densely populated areas such as high-rise buildings and underground facilities. In emergencies, fire emergency lights can quickly illuminate, providing clear guidance for personnel evacuation and fire rescue. They also effectively improve escape efficiency by indicating evacuation directions with graphics and text, making them an important facility for ensuring life safety. Currently, traditional fire emergency lights are generally installed with fixed bases, requiring manual installation at height by tightening screws and pressing clips. The bases themselves lack lifting and automatic locking functions, necessitating the use of ladders, aerial work platforms, and other tools for installation, maintenance, and replacement. This is not only cumbersome and inefficient but also poses a risk of falls from heights. Furthermore, traditional structures are difficult to align and lack pre-positioning capabilities, making installation difficult for a single person. Subsequent maintenance requires further disassembly at height, significantly increasing maintenance costs and safety hazards. This approach fails to meet the dual requirements of safe and stable fire equipment and convenient maintenance. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a quick-install base structure for fire emergency lights with magnetic fixation, which effectively solves the problem that the existing fire emergency light installation structure cannot be disassembled and installed in an integrated manner by lifting and locking, requiring high-altitude operations, which makes installation and maintenance very inconvenient and poses safety hazards.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a quick-install base structure for a fire emergency light with magnetic fixation, comprising a mounting base, a positioning plate fixedly connected to the rear side of the mounting base, and connection holes for wall fixing at the four corners of the positioning plate; a support base is provided below the mounting base, the fire emergency light body to be installed is placed on the upper surface of the support base, and a support plate is fixed to the rear side of the support base; locking holes are provided at both the left and right ends of the fire emergency light body, and two docking holes are provided at the inner bottom of the support base; two upper magnets adapted to the size of the docking holes are fixedly installed at the bottom of the fire emergency light body, and lower magnets are fixed at the inner bottom of each docking hole; the two upper magnets are inserted into the two docking holes respectively, and form magnetic attraction and fixation with the two lower magnets, thereby completing the initial magnetic positioning of the fire emergency light body.

[0005] A servo motor is fixedly installed on the lower front side of the positioning plate via a fixing plate. The output end of the servo motor is equipped with a linkage component. When the servo motor rotates in the forward direction, it can drive the linkage component to move, thereby driving the support base to move smoothly upward to the installation position. After the support base is in place, it simultaneously engages and locks the fire emergency light body, completing the fully automatic installation of the fire emergency light body in one go.

[0006] Preferably, the linkage component includes a driving bevel gear fixedly installed at the output end of the servo motor. The top of the driving bevel gear is rotatably connected to the positioning plate via a rotating seat and achieves rotational positioning. A driven bevel gear is meshed with one side of the surface of the driving bevel gear. A winding wheel is coaxially fixedly connected to one side of the driven bevel gear via a rotating shaft. One side of the winding wheel is rotatably connected to the positioning plate via a positioning seat. The surface of the rotating shaft is rotatably positioned with the positioning plate via a shaft seat, ensuring that the driven bevel gear, the rotating shaft, and the winding wheel rotate stably and coaxially without shaking or deviation.

[0007] Preferably, a lifting rope is wound around the surface of the reel, and a through hole is provided on the mounting base; the free end of the lifting rope passes upward through the through hole and extends downward toward the front of the mounting base, and the free end of the lifting rope is fixedly connected to the support plate on the support base, so that the lifting and lowering of the support base can be achieved by reeling in the lifting rope.

[0008] Preferably, a rotating frame is fixedly installed at the center of the top of the mounting base, and a guide wheel is rotatably positioned on the upper part of the rotating frame; the suspension rope is wound around the outer surface of the guide wheel, and the guide wheel realizes the support, reversal and friction reduction of the suspension rope, so as to ensure stable transmission of tension.

[0009] Preferably, the front part of the upper end face of the mounting base is fixed with a positioning sleeve by a fixing seat. The positioning sleeve is movably sleeved on the surface of the hoisting rope to limit the movement path of the hoisting rope and prevent the hoisting rope from shifting left or right, getting tangled or stuck during the lifting process.

[0010] Preferably, guide sleeves are fixedly installed on both the left and right sides of the support base, and guide rods are movably inserted into the middle of the guide sleeves; a locking head is fixed at the inner end of the guide rods that are close to each other, and the two locking heads are adapted to the size of the two locking holes at both ends of the fire emergency light body, so that they can be accurately locked into the locking holes to achieve lateral locking and positioning; the outer ends of the guide rods are rotatably installed with pulleys through the connecting frame, and push strips are fixed on both sides of the front of the mounting base; the two push strips cooperate with the pulleys as the support base rises to achieve opposing compression of the two pulleys, pushing the guide rods and locking heads inward and clamping them; a transverse spring is sleeved on the surface of the guide rods, and the two ends of the transverse springs are fixedly connected to the guide sleeves and the connecting frame respectively, so as to drive the locking heads to automatically reset and unlock when disassembling.

[0011] Preferably, two insert sleeves are fixedly installed on the front side of the support plate, and support arms are fixedly installed on both the left and right sides of the top of the mounting base; the free ends of the two support arms extend horizontally forward of the mounting base, and insert rods are movably inserted into the free ends of the two support arms; a pressure plate is fixed in the middle of each insert rod, and a vertical spring is sleeved on the surface of each insert rod; the two ends of the vertical spring are fixedly connected to the support arm and the pressure plate respectively, and the two insert rods correspond to the positions of the two insert sleeves and are adapted in size. After the support base rises to the position, the insert rods are inserted into the insert sleeves to achieve vertical pressing and secondary positioning.

[0012] Preferably, the transverse spring is covered with a second corrugated sleeve, and the two ends of the second corrugated sleeve are fixedly connected to the guide sleeve and the connecting frame, respectively, to achieve dustproof, waterproof and corrosion-proof protection for the transverse spring; the vertical spring is covered with a first corrugated sleeve, and the two ends of the first corrugated sleeve are fixedly connected to the support arm and the pressure plate, respectively, to achieve sealed protection for the vertical spring and extend the service life of the spring.

[0013] Preferably, the upper end of each docking hole is provided with a first arc-shaped chamfer to enlarge the entrance opening of the docking hole, making it easier for the upper magnet to be quickly aligned and inserted, and reducing the difficulty of alignment; the top opening of the positioning sleeve is provided with a second arc-shaped chamfer to remove sharp edges, prevent the suspension rope from being cut or worn during reciprocating motion, and improve the safety of use.

[0014] Preferably, the bottom of the positioning plate is fixed with two slide rails, and each slide rail has a groove on its front side; both ends of the rear side of the support base are fixed with sliders, and the two sliders are slidably installed in the two grooves to limit and guide the lifting and lowering movement of the support base, so as to ensure that the lifting and lowering is smooth, without deviation or falling off.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) In operation, the fire emergency light can be docked and placed on the ground by low-position magnetic pre-positioning and electric automatic lifting structure. The motor will automatically lift it to the installation position. No manual climbing is required throughout the process, which completely eliminates the safety risks of climbing for installation and maintenance and greatly improves the efficiency of installation and maintenance. (2) By setting an electromagnetic power failure brake, the output shaft and the reel are mechanically locked when the motor stops, which effectively prevents the support base and emergency light from sliding down due to gravity, and significantly improves the safety and stability of the stop position. (3) During operation, after the support seat rises to the position, the horizontal clamping of the clamp head and the vertical elastic pressing of the insertion rod can be achieved simultaneously, forming a double mechanical lock. Combined with magnetic fixation, it forms a multi-layered stable structure that is vibration resistant, does not loosen, and does not fall off, fully meeting the requirements for long-term reliable operation of fire-fighting equipment. (4) When disassembling, the motor reverses to unlock, the vertical spring releases elastic potential energy to assist in pushing and the support seat moves down under the dual drive of gravity. The fall is smooth without jamming or impact. It can quickly descend to the low position without manual assistance. The disassembly and assembly process is simple and quick. (5) The overall structure is equipped with multiple guiding mechanisms such as guide wheels, positioning sleeves, and slide rail sliders, which ensure smooth operation and precise positioning. At the same time, the corrugated sleeve is set to seal and protect the spring, making it dustproof, waterproof, and with a longer service life, suitable for long-term use in various fire protection scenarios.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] Depend on Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The present invention includes a mounting base 1, a positioning plate 2 fixedly connected to the rear side of the mounting base 1, and connection holes 3 at the four corners of the positioning plate 2 for fixing the overall structure to a wall or mounting base. A support base 4 is provided below the mounting base 1, and the fire emergency light body 5 is placed on the upper surface of the support base 4. A support plate 6 is fixed to the rear side of the support base 4. The fire emergency light body 5 has symmetrical locking holes 7 at both ends. Two docking holes 8 are provided at the bottom of the support base 4. Two upper magnets 10 are fixed to the bottom of the fire emergency light body 5, and a lower magnet 11 is fixed to the bottom of the docking hole 8. The upper magnets 10 and lower magnets 11 are positioned correspondingly. The upper magnets 10 are inserted into the docking hole 8 and magnetically attracted to the lower magnets 11, completing the initial magnetic positioning of the fire emergency light body 5. The servo motor 13 is fixedly installed on the lower front side of the positioning plate 2 via the fixing plate 12. The servo motor 13 is equipped with an electromagnetic power failure brake. When the servo motor 13 stops, the output shaft is immediately locked to prevent the support seat from sliding down unexpectedly. The output end of the servo motor 13 is equipped with a linkage component. When the servo motor 13 rotates in the forward direction, it drives the linkage component to move, causing the support seat 4 to move upward to the installation position. At the same time, it triggers the snap-fit ​​structure to lock the fire emergency light body 5, completing the quick installation.

[0020] Two slide rails 22 are symmetrically fixed at the bottom of the positioning plate 2. A slide groove 23 is opened on the front side of the slide rail 22. Slider 24 is fixed at both ends of the rear side of the support base 4. The slider 24 is slidably engaged in the slide groove 23 to guide and limit the lifting and lowering movement of the support base 4, ensuring that the lifting and lowering process is smooth, without deviation or jamming.

[0021] Depend on Figure 7 The linkage assembly includes an active bevel gear 14 fixed to the output end of the servo motor 13. The top of the active bevel gear 14 is rotatably connected to the positioning plate 2 via a rotating seat 16 to achieve rotational positioning. One side of the active bevel gear 14 meshes with a driven bevel gear 15, and one side of the driven bevel gear 15 is coaxially fixed to a winding wheel 19 via a rotating shaft 17. The middle part of the rotating shaft 17 is rotatably connected to the positioning plate 2 via a shaft seat 18, and one side of the winding wheel 19 is rotatably connected to the positioning plate 2 via a positioning seat 20, ensuring that the driven bevel gear 15, the rotating shaft 17, and the winding wheel 19 rotate stably and coaxially without shaking or deviation. The surface of the reel 19 is wound with a hanging rope 21. A through hole 43 is opened in the middle of the mounting base 1. The free end of the hanging rope 21 passes through the through hole 43 and extends forward, and finally is fixedly connected to the upper end of the support plate 6. The servo motor 13 drives the reel 19 to wind up the hanging rope 21, and the hanging rope 21 pulls the support plate 6 and the support base 4 to move upward as a whole.

[0022] Depend on Figure 8 and Figure 9 As shown, a rotating frame 26 is fixed at the top center of the mounting base 1, and a guide wheel 25 is rotatably mounted on the upper part of the rotating frame 26. The lifting rope 21 is wound around the surface of the guide wheel 25. The guide wheel 25 changes the direction of force on the lifting rope 21 and reduces friction loss. A positioning sleeve 27 is fixed at the front of the upper end of the mounting base 1 through a fixed seat 28. The positioning sleeve 27 is movably sleeved on the outside of the lifting rope 21 to limit the left and right displacement of the lifting rope 21 and ensure that the lifting rope 21 moves along a fixed trajectory. Two insert sleeves 30 are symmetrically fixed on the front side of the support plate 6. Support arms 31 are fixed on both sides of the top of the mounting base 1. The free ends of the support arms 31 extend forward and are movably inserted into the insert rods 32. A pressure plate 34 is fixed in the middle of the insert rods 32. A vertical spring 33 is sleeved on the surface of the insert rods 32. The two ends of the vertical spring 33 are fixed to the support arms 31 and the pressure plate 34 respectively. After the support base 4 is raised to the position, the lower end of the insert rod 32 is inserted into the insert sleeves 30. The vertical spring 33 provides downward pressure to achieve vertical pressing and positioning of the support base 4.

[0023] Depend on Figure 5 and Figure 6 The support base 4 is provided with symmetrically fixed guide sleeves 44 on both sides. Guide rods 37 are movably inserted into the guide sleeves 44. A clamp 38 is fixed to the inner end of the guide rod 37. The clamp 38 is adapted to the size of the clamp hole 7 and can be inserted into the clamp hole 7 to achieve lateral locking of the fire emergency light body 5. The outer end of the guide rod 37 is rotatably mounted with a pulley 42 through a connecting bracket 41. Pushing strips 36 are fixed on both sides of the front part of the mounting base 1. During the rise of the support base 4, the pushing strips 36 contact the pulley 42 and push inward, causing the guide rod 37 to drive the clamp 38 to move inward. A transverse spring 39 is sleeved on the surface of the guide rod 37. The two ends of the transverse spring 39 are fixed to the guide sleeve 44 and the connecting bracket 41 respectively. When disassembling, the transverse spring 39 drives the guide rod 37 and the clamp 38 to reset and release the clamp.

[0024] Depend on Figure 5 , Figure 6 , Figure 8 as well as Figure 9 As shown, a second corrugated sleeve 40 is fitted over the transverse spring 39, with guide sleeve 44 and connecting bracket 41 fixed at both ends of the second corrugated sleeve 40, to seal and protect the transverse spring 39 from dust and water; a first corrugated sleeve 35 is fitted over the vertical spring 33, with support arm 31 and pressure plate 34 fixed at both ends of the first corrugated sleeve 35, to seal and protect the vertical spring 33 and prevent the spring from rusting and failing. A first arc-shaped chamfer 9 is provided at the upper opening of the docking hole 8 to enlarge the entrance size of the docking hole 8, reduce the difficulty of aligning the upper magnet 10, and facilitate quick insertion; a second arc-shaped chamfer 29 is provided at the top opening of the positioning slide sleeve 27 to remove sharp edges, prevent the suspension rope 21 from being cut during movement, and improve the safety of use.

[0025] Before installation, the positioning plate 2 is fixed to the wall through the connecting hole 3. During installation, the fire emergency light body 5 is placed on the support base 4. The upper magnet 10 at the bottom is quickly inserted along the first arc chamfer 9 at the top of the docking hole 8 and magnetically attracted to the lower magnet 11 to complete the initial positioning. The servo motor 13 is started to rotate in the forward direction. The active bevel gear 14 drives the driven bevel gear 15, the rotating shaft 17 and the winding wheel 19 to rotate synchronously. The winding wheel 19 winds up the hanging rope 21. The hanging rope 21 is supported by the guide wheel 25 and reversed and limited by the positioning sleeve 27. The support plate 6 and the support base 4 are pulled to rise smoothly along the slide groove 23 of the slide rail 22 through the slider 24. During the rising process, the pulleys 42 on both sides of the support seat 4 are pressed inward by the push bar 36 at the front of the mounting seat 1, causing the guide rod 37 to slide in the guide sleeve 44 and drive the clamp head 38 to engage with the clamp hole 7 of the fire emergency light body 5 to achieve horizontal locking. At the same time, the support seat 4 rises to the position, and the insert rods 32 on the support arms 31 on both sides of the mounting seat 1 are inserted into the insert sleeve 30 on the front side of the support plate 6 under the elastic force of the vertical spring 33 to achieve vertical pressing and positioning. The horizontal spring 39 and the vertical spring 33 are sealed and protected by the second corrugated sleeve 40 and the first corrugated sleeve 35 respectively. The second arc chamfer 29 at the top of the positioning sleeve 27 can avoid cutting the hoisting rope 21. During disassembly, the servo motor 13 is controlled to rotate in the reverse direction, the reel 19 releases the hoisting rope 21, the upward pull of the hoisting rope 21 disappears, the vertical spring 33 releases elastic potential energy to push the pressure plate 34 and the insertion rod 32 downward, assisting in pushing the support base 4 to move down. At the same time, the support base 4 moves down smoothly under its own weight until it returns to the initial disassembly position. When the support base 4 moves down, it will drive the two pulleys 42 to leave the area between the two push bars 36. Under the rebound action of the horizontal spring 39, the guide rod 37 drives the clasp 38 to exit the clasp hole 7 to release the horizontal lock. At the same time, the insertion rod 32 disengages from the insertion sleeve 30. At this time, the upper magnet 10 and the lower magnet 11 still maintain a slight attraction, and the fire emergency light body 5 can be directly removed to complete the entire disassembly process. This allows operators to install or remove the fire emergency light body 5 without having to climb, making the entire disassembly and assembly process safe and convenient.
