Description

Technical Field

[0001] The utility model belongs to the technical field of LED lampshades, and specifically relates to an LED explosion-proof lampshade. Background Art

[0002] An LED lampshade is an accessory for LED lamps, designed to better focus and soften the light, while preventing direct glare from the LED light. The main function of a lampshade is to diffuse the light more evenly and softly, without causing glare. This protects the eyes and ensures that the lamp is more functional. Its light transmittance must be within a certain range, ensuring that not too much light is wasted within the shade. It must also be able to diffuse the light through the film layer into every space, preventing the internal lamp beads from being visible while maximizing light dispersion.

[0003] LED explosion-proof lamps are the same as explosion-proof lamps. The difference from explosion-proof lamps is that the light source uses LED. In order to prevent the ignition of surrounding explosive mixtures such as explosive gas environments, explosive dust environments, and gas, various specific measures are taken for lamps. In order to achieve the explosion-proof effect, LED explosion-proof lampshades are usually used to protect the LED lamps. However, when the LED lamp fails, the entire LED lamp needs to be disassembled together with the lampshade for inspection or replacement. The disassembly and assembly process is cumbersome. In view of this, the utility model is specially proposed to provide an LED explosion-proof lampshade to solve the above problems. Utility Model Content

The following embodiments are used to illustrate the present invention.

[0024] like Figures 1 to 6 shown

[0025] An LED explosion-proof lampshade includes a lampshade body 1, a mounting bracket 2 is fixedly connected to the top of the lampshade body 1, and symmetrical mounting holes 3 are opened on both sides of the mounting bracket 2. The LED lamp is installed on the inner side of the lampshade body 1. After the installation is completed, the lampshade body 1 is fixed to the wall through the mounting bracket 2 and the mounting hole 3 with bolts. The lampshade body 1 has symmetrical rectangular mounting openings on the front and back sides, and the inner walls of the rectangular mounting openings are slidably provided with heat conducting plates 4. The outer walls of one side of the two heat conducting plates 4 are fixedly provided with equidistantly distributed heat sinks 5. The heat conducting plates 4 and the heat sinks 5 can be used to heat the inside of the lampshade body 1 by heat exchange. The heat is dissipated, which has a cooling effect on the interior of the lampshade body 1, avoiding the explosion of the lampshade body 1 due to the large temperature difference between the inside and the outside, and improving the explosion-proof performance of the lampshade body 1. The right outer wall of the two heat conducting plates 4 is fixedly connected with the mounting plate 6, and the outer wall of the opposite side of the two mounting plates 6 is fixedly connected with the limit rod 7. The two limit rods 7 are symmetrical with each other, and the opposite ends of the two limit rods 7 are both inclined. The right outer wall of the lampshade body 1 is fixedly connected with the limit seat 8, and symmetrically arranged connecting grooves 12 are opened on both sides of the limit seat 8. The two limit rods 7 are respectively slidably set in the two connecting grooves 12, and the inner walls at the bottom of the two connecting grooves 12 are opened. The movable groove 13, the inner walls of the two movable grooves 13 are slidably connected to the limit card block 14, the bottom of the two movable grooves 13 are provided with a through hole, and the inner wall of the through hole is slidably connected with a slide rod 15, the top of the two slide rods 15 are respectively fixedly connected to the outer wall of the bottom of the two limit card blocks 14, and the bottom ends of the two slide rods 15 are fixedly connected to the same connecting rod 17, and the two limit rods 7 are provided with a limit card slot 18, and the limit card block 14 is slidably set on the inner wall of the limit card slot 18. When the LED fails, the connecting rod 17 is pulled to move, and the connecting rod 17 drives the two slide rods 15 to move, and the two slide rods 15 drive the two limit card blocks 14 to Move, so that the two limit blocks 14 are disengaged from the two limit slots 18 respectively. After the two limit blocks 14 are disengaged from the two limit slots 18 respectively, the two mounting plates 6 are pulled to move in opposite directions, and the two mounting plates 6 drive the two limit rods 7 to move in opposite directions. At the same time, the two mounting plates 6 drive the two heat conducting plates 4 to move in opposite directions until the two limit rods 7 are disengaged from the two connecting grooves 12 respectively, and the two heat conducting plates 4 are disengaged from the front and rear sides of the lampshade body 1, so that the heat conducting plates 4 can be removed from the lampshade body 1, which is convenient for the staff to inspect or replace the LED lamp in the lampshade body 1 through the rectangular mounting port of the heat conducting plate 4.

[0026] In a specific embodiment, the bottom ends of the two slide rods 15 extend to the outside of the bottom of the limit seat 8, the inner walls of the bottom of the two movable grooves 13 are fixedly connected to the compression springs 16, the tops of the two compression springs 16 are respectively fixedly connected to the outer walls of the bottom of the two limit blocks 14, and the two compression springs 16 are respectively sleeved on the two slide rods 15. The left sides of the two heat conducting plates 4 are fixedly connected to the fixing plates 9, and the outer walls of the opposite sides of the two fixing plates 9 are fixedly connected to the guide rods 11. The left outer wall of the lampshade body 1 is fixedly installed with a support seat 10, and the guide grooves 19 arranged symmetrically on both sides of the support seat 10 are opened, and the guide rods 11 are fixedly installed on the left outer wall of the lampshade body 1. The slide is set on the inner wall of the guide groove 19. After the LED lamp is repaired or replaced, the guide rod 11 is aligned with the guide groove 19 so that the guide rod 11 slides on the inner wall of the guide groove 19. At the same time, the limit rod 7 is aligned with the connecting groove 12 and the limit rod 7 is pushed to slide in the connecting groove 12. When the limit slot 18 opened on the limit rod 7 moves to the side of the limit block 14, the limit block 14 can be pushed into the limit slot 18 under the action of the compression spring 16, thereby realizing the positioning of the limit rod 7. At this time, the heat conducting plate 4 moves to the inside of the rectangular mounting opening to complete the positioning and installation of the heat conducting plate 4.

[0027] The implementation principle of an LED explosion-proof lampshade of this embodiment is as follows:

[0028] When in use, the LED lamp is installed on the inner side of the lampshade body 1. After the installation is completed, the lampshade body 1 is fixed to the wall through the mounting bracket 2 and the mounting hole 3 with bolts. Then, the heat inside the lampshade body 1 can be dissipated through the provided heat conducting plate 4 and the heat sink 5 by means of heat exchange, which plays a role in cooling the inside of the lampshade body 1, avoiding the lampshade body 1 from exploding due to the large temperature difference between the inside and the outside, thereby improving the explosion-proof performance of the lampshade body 1. When the LED fails, the connecting rod 17 is pulled to move, and the connecting rod 17 drives the two sliding rods 15 to move, and the two sliding rods 15 drive the two limit blocks 14 to move, so that the two limit blocks 14 are respectively disengaged from the two limit slots 18. After the two limit blocks 14 are respectively disengaged from the two limit slots 18, the two mounting plates 6 are pulled to move in opposite directions, and the two mounting plates 6 drive the two limit rods 7 to move in opposite directions. When the two fixing plates 6 drive the two heat conducting plates 4 to move in opposite directions, the two limiting rods 7 are respectively disengaged from the two connecting grooves 12, and the two heat conducting plates 4 are disengaged from the front and rear sides of the lampshade body 1, so that the heat conducting plates 4 can be removed from the lampshade body 1, which is convenient for the staff to repair or replace the LED lamp in the lampshade body 1 through the rectangular mounting opening of the heat conducting plate 4. After the repair or replacement is completed, the guide rod 11 is aligned with the guide groove 19 so that the guide rod 11 slides on the inner wall of the guide groove 19. At the same time, the limiting rod 7 is aligned with the connecting groove 12 and pushes the limiting rod 7 to slide in the connecting groove 12. When the limiting card slot 18 opened on the limiting rod 7 moves to one side of the limiting card block 14, the compression spring 16 can push the limiting card block 14 into the limiting card slot 18 to realize the positioning of the limiting rod 7. At this time, the heat conducting plate 4 moves to the inside of the rectangular mounting opening, completing the positioning and installation of the heat conducting plate 4.
