Description

Technical Field

[0001] This invention relates to the field of lighting technology, specifically to a fall-proof ceiling light fixture. Background Technology

[0002] Ceiling lights are a type of lighting fixture. As the name suggests, they are called ceiling lights because the top of the fixture is relatively flat and the bottom is completely attached to the ceiling during installation. Light sources include ordinary incandescent bulbs, fluorescent lamps, high-intensity discharge lamps, halogen lamps, and LEDs. Currently, the most popular ceiling lights on the market are LED ceiling lights, which are frequently chosen for various places such as homes, offices, and entertainment venues. Different light sources are suitable for different places. For example, ceiling lights using ordinary incandescent bulbs and fluorescent lamps are mainly used for lighting in spaces with a ceiling height of about four meters, such as homes, classrooms, and office buildings. High-intensity discharge lamps, which have larger power and larger light source volume, are mainly used for lighting in places with a ceiling height of four to nine meters, such as stadiums, large shopping malls, and factories. In order to achieve sufficient height for the work surface while saving electricity, fluorescent ceiling lights are usually the first choice for lighting in homes, schools, shops, and offices.

[0003] Existing ceiling lights may not be securely installed, making them difficult to prevent from falling and hindering normal use. This also reduces their safety. Using multiple bolts or other excessive fixing structures for stability makes disassembly and assembly more difficult. Furthermore, in humid environments such as bathrooms, moisture entering the light fixture can damage internal components. Therefore, improvements are needed. Summary of the Invention

Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1 to 5This invention provides a technical solution: a fall-proof ceiling light fixture, comprising a fixing base 1, with several fixing screws 2 on the edge of the fixing base 1, each fixing screw 2 having a sealing ring. The fixing screws 2 can be used to fix the fixing base 1 in the installation position. The fixing base 1 has a mating groove 3, and a lamp panel assembly for easy disassembly and assembly is provided on the mating groove 3. The lamp panel assembly includes a lamp panel 4. Several spring posts are installed in the middle of the mating groove 3. After the lamp panel 4 is installed, the spring posts are in a compressed state. When disassembling, the lamp panel 4 can be pushed down for easy disassembly. A lamp holder 5 is provided on the top surface of the lamp panel 4, and the lamp holder 5 is embedded in the mating groove 3. The outer walls on both sides of the lamp holder 5 are provided with slots 501. The mating groove 3 has a hollow structure. An inner plate 6 is provided on each side of the mating groove 3. A locking tooth 601 is connected to one side surface of the inner plate 6. 601 is snapped into the slot 501, and a first spring 7 is connected to the other side surface of the inner plate 6; one inner plate 6 has side plates 602 installed at both ends, and a first rack 603 is provided at the end of the side plate 602; the other inner plate 6 has a second rack 604 at both ends, and a transmission gear 605 is provided between the second rack 604 and the first rack 603. The transmission gear 605 meshes with the second rack 604 and the first rack 603 respectively; when the left inner plate 6 moves, it can drive the side plate 602 to move, and the first rack 603 moves accordingly, causing the transmission gear 605 to rotate. The rotation of the transmission gear 605 can drive the second rack 604 to move, thereby causing the right inner plate 6 to move. Therefore, the two inner plates 6 can move synchronously in opposite directions. When disassembling, only the left inner plate 6 needs to be pulled.

[0025] The mounting base 1 is connected to a waterproof and sealable lamp housing assembly, which includes a lamp housing 17. A mating ring 18, made of transparent material, is provided on the inner surface of the lamp housing 17. The edge of the mounting base 1 is embedded inside the mating ring 18. The mounting base 1 is an assembled structure. An inner cavity 19 is provided inside the edge of the mounting base 1. A movable ring 20, an annular plate, is provided inside the inner cavity 19. A first airbag 21 is connected to the top of the movable ring 20, and two second airbags 25 are provided below the inner cavity 19. The second airbag 25 has a ring structure. The first airbag 21 and the second airbag 25 are connected. A side rod 22 is provided on the inner wall of the movable ring 20. A pressing member 23 is installed on the inner wall of the docking ring 18. When the pressing member 23 moves upward and pushes the side rod 22, the movable ring 20 rises, which in turn causes the air inside the first airbag 21 to be squeezed into the second airbag 25. The expansion of the second airbag 25 can block the gap at the connection between the fixed seat 1 and the docking ring 18, which greatly improves the sealing performance. The pressing member 23 is connected to an installation mechanism.

[0026] The mounting mechanism includes a sliding movable plate 11. A hook 14 is provided on the bottom surface of the end of the movable plate 11. A fixing groove 24 is provided on the side wall of the end of the pressing member 23. The hook 14 is engaged in the fixing groove 24. A fixing block 9 is installed inside the fixing base 1. Two clamping blocks 10 are installed at the bottom of the fixing block 9. The clamping blocks 10 are slidably embedded in the two sides of the movable plate 11. A traction belt 8 is connected between one end of the movable plate 11 and the inner plate 6. A connecting rod 12 is inserted into the other end of the movable plate 11. A second spring 13 is connected to the end of the connecting rod 12. The other end of the connecting rod 12 passes through the fixing base 1 and is rotatably connected to a rotating sleeve 15. The rotating sleeve 15 is screwed onto the protrusion 16.

[0027] During installation, first fix the mounting base 1 in the installation position using fixing screws 2, then align the lamp holder 5 with the docking groove 3 and push the lamp plate 4 upward. The lamp holder 5 first squeezes the retaining teeth 601 to compress the first spring 7. When the lamp plate 4 is pushed to the top, the first spring 7 rebounds and pushes the inner plate 6, which allows the retaining teeth 601 to be embedded in the retaining groove 501, thus securing the lamp plate 4. When installing the lamp housing 17, cover the edge of the mounting base 1 with the docking ring 18. The hook 14 will automatically engage in the fixing groove 24. At the same time, the pressing part 23 pushes the side rod 22 to raise the movable ring 20, which in turn compresses the air inside the first airbag 21 into the second airbag 25. The expansion of the second airbag 25 can block the gap at the connection between the mounting base 1 and the docking ring 18, greatly improving the sealing performance.

[0028] During disassembly, simply rotate the rotating sleeve 15. The connecting rod 12 can pull the movable plate 11 outward, causing the hook 14 to disengage from the fixing groove 24. The depth to which the locking teeth 601 embed into the locking groove 501 is greater than the depth to which the hook 14 embeds into the fixing groove 24. Therefore, when the hook 14 disengages from the fixing groove 24, even if the movable plate 11 pulls the inner plate 6 to move, the locking teeth 601 will not disengage from the locking groove. The internal lamp panel 4 can only be removed when the lamp housing 17 is removed. Pull the lamp housing 17 downward to remove it. Then push the movable plate 11 to both sides, and pull the inner plate 6 through the traction belt 8. The locking teeth 601 disengage from the locking groove 501, and the lamp panel 4 can be removed from the docking groove 3. Disassembly and assembly are simpler. Because it is equipped with a lamp panel assembly that is easy to disassemble and install, and a waterproof and sealable lamp housing assembly, the lamp is installed firmly and will not fall. It is also easy to operate during disassembly and assembly, and has good sealing performance, making it more practical and safer.
