Description

Technical Field

[0001] This invention relates to a lighting device, and more particularly to a quick-release LED explosion-proof light. Background Technology

[0002] Explosion-proof lights are special lighting equipment suitable for flammable and explosive hazardous locations such as petroleum, chemical, mining, and metallurgical industries. Their core function is to prevent electrical sparks and high-temperature surfaces generated during operation from igniting surrounding explosive mixtures in highly hazardous environments such as flammable gases and dust, thus ensuring on-site operational safety. With the widespread adoption of LED light sources' advantages such as high efficiency, energy saving, and long lifespan, LED explosion-proof lights have gradually replaced traditional light sources and become the mainstream product in the explosion-proof lighting field.

[0003] LED explosion-proof lights often operate under harsh conditions such as high temperature, high power, high dust, and high vibration. Significant heat accumulates inside the lamp body, and the LED light board is constantly subjected to thermal stress and environmental corrosion, which can easily lead to problems such as premature decay of LED beads, aging and cracking of PCB board, and failure of solder joints. This results in a high failure rate of the light board and requires frequent maintenance and replacement.

[0004] The existing LED explosion-proof lights generally use multiple screws to fix the lamp cover and heat dissipation structure. The assembly and disassembly process requires tightening each screw one by one, which is cumbersome, time-consuming, and inefficient, making it difficult to meet the needs of rapid maintenance in industrial sites. Summary of the Invention

[0005] Therefore, it is necessary to provide a quick-release LED explosion-proof light to address the shortcomings of existing technologies.

[0006] A quick-release LED explosion-proof light includes a heat sink housing, several sets of locking assemblies mounted on the heat sink housing, a lamp plate mounted on the locking assemblies, a lampshade extending into the heat sink housing, and a fixing component mounted on the heat sink housing and pressing the locking assemblies to limit the lampshade. The heat sink housing includes a main body base with an upwardly extending receiving groove at the bottom. The main body base also has a connecting post within the receiving groove. Each set of locking assemblies includes a heat-conducting plate, a limiting rod sliding on the heat-conducting plate, a limiting post mounted on the limiting rod, and a return spring elastically abutting against the limiting post and the heat-conducting plate. One end of the limiting rod is a first mating end, which has an inclined first guide surface. The first inclined guide surface on the first mating end is inclined downwards, and the first inclined guide surfaces on different locking assemblies enclose a mating space that gradually contracts upwards. The fixing component includes a bottom cap and a connector. The outer periphery of the connector away from the bottom cap has a conical extrusion surface, and the outer diameter of the connector corresponding to the extrusion surface gradually contracts from the direction away from the bottom cap. When installing the fastener, the fastener is installed on the connecting column. The pressing surface of the fastener presses against the first inclined guide surface of the limiting rod, so that the limiting rod passes through the lampshade and is installed on the heat dissipation housing, thereby completing the installation and fixing of the lampshade. When removing the fastener, the return spring pushes the limiting rod out from the heat dissipation housing and the lampshade, thereby releasing the limiting of the lampshade.

[0007] In one embodiment, the outer surface of the connecting post is provided with external threads, and the middle of the end of the connecting head away from the bottom cap is provided with an inwardly extending mounting hole. The wall of the mounting hole is provided with internal threads, and the internal threads of the fastener are fitted with the external threads of the connecting post for installation.

[0008] In one embodiment, the connector is vertically connected to the bottom cap, the outer diameter of the bottom cap is larger than the outer diameter of the connector, the bottom of the lampshade is provided with a mounting groove in the middle, the middle of the mounting groove extends upward to form a through hole, the mating space and the through hole are aligned with each other in the vertical direction, when the fastener is installed on the heat dissipation housing, the fastener passes through the mounting groove and the through hole.

The main body is provided with a plurality of slots, which extend horizontally outward from the side wall of the receiving groove. The lampshade includes a lampshade body and a connecting part vertically connected to the upper end face of the lampshade body. The connecting part is provided with a plurality of through holes, which penetrate the connecting part horizontally. When the pressing surface of the fixing member extends into the mating space and presses the first inclined guide surface of all the limiting rods, the limiting rods move outward under the cooperation of the pressing surface and the first inclined guide surface. The limiting post presses the return spring, causing the return spring to elastically contract. During the outward movement of the limiting rod, the second inclined guide surface presses upward against the hole wall of the through hole, causing the lampshade to move upward, and the second mating end of the limiting rod is engaged in the slot.

[0010] In one embodiment, the slots are evenly spaced around the positioning post, with the slot openings facing the positioning post; the perforations are evenly spaced around the central axis of the lampshade, with the perforations facing the central axis of the lampshade.

[0011] In one embodiment, the main body seat is provided with a plurality of positioning posts in the receiving groove. The positioning posts are arranged vertically and one side of the positioning posts is connected to the side wall of the receiving groove. The connecting part is provided with a plurality of positioning grooves.

[0014] In one embodiment, the heat-conducting plate includes a plate body and two guide portions connected to the bottom of the plate body. The two guide portions are arranged along the main axis of the plate body. The guide portions are provided with adjustment holes, which penetrate the guide portions along the main axis of the plate body. The adjustment holes on the two guide portions are arranged opposite to each other. The limiting rod passes through the adjustment holes of the two guide portions simultaneously. The first mating end extends out from the through hole of one guide portion, and the second mating end extends out from the through hole of the other guide portion.

When removing the fixing parts, the limiting rod is removed from the heat dissipation housing and the lampshade, thereby releasing the limiting of the lampshade. The entire disassembly and assembly process is convenient and quick, effectively saving maintenance time and demonstrating strong practicality. Attached Figure Description

[0024] Please see Figures 1 to 11 This invention provides a quick-release LED explosion-proof light, including a heat sink housing 10, several sets of locking components 30 mounted on the heat sink housing 10, a lamp plate 40 mounted on the locking components 30, a lamp cover 20 extending into the heat sink housing 10, and a fixing member 50 mounted on the heat sink housing 10 and pressing the locking components 30 to limit the lamp cover 20. After the fixing member 50 is removed from the heat sink housing 10, the locking components 30 release the restriction on the lamp cover 20. At this time, the lamp cover 20 can be removed from the heat sink housing 10 to replace the lamp plate 40.

[0025] The heat dissipation housing 10 includes a main body 11 and several heat dissipation fins 12 mounted on the upper surface of the main body 11. The heat dissipation fins 12 are arranged sequentially along a horizontal direction on the main body 11. The bottom of the main body 11 is provided with an upwardly extending receiving groove 111. The cavity of the receiving groove 111 is circular. The main body 11 is also provided with connecting posts 112 and several positioning posts 114 within the receiving groove 111. One end of the connecting post 112 is vertically connected to the center of the top wall of the receiving groove 111. The positioning posts 114 are vertically arranged, with one side connected to the side wall of the receiving groove 111. The positioning posts 114 are evenly spaced around the connecting post 112. The outer surface of the connecting post 112 is provided with external threads. In addition, the main body 11 is also provided with a first waterproof groove 115 and several retaining slots 113. The first waterproof groove 115 is located at the bottom edge of the main body 11 and is distributed around the opening of the receiving groove 111. The slot 113 extends horizontally outward from the side wall of the receiving slot 111, and the slots 113 are evenly spaced around the positioning post 114, with the slot openings of the slots 113 facing the positioning post 114.

[0026] Each set of positioning components 30 includes a heat-conducting plate 31, a limiting rod 32 slidably mounted on the heat-conducting plate 31, a limiting post 34 mounted on the limiting rod 32, and a return spring 33 elastically abutting against the limiting post 34 and the heat-conducting plate 31. The heat-conducting plate 31 includes a plate body 311 and two guide portions 312 connected to the bottom of the plate body 311. The two guide portions 312 are arranged along the main axis of the plate body 311. The guide portions 312 are provided with adjustment holes 313, which penetrate the guide portions 312 along the main axis of the plate body 311. The adjustment holes 313 on the two guide portions 312 are arranged opposite to each other. An adjustment space 314 is formed between the two guide portions 312, and the return spring 33 and the limiting post 34 are disposed in the adjustment space 314.

[0027] The limiting rod 32 has a first mating end 321 and a second mating end 322 at its two ends. The first mating end 321 has a first inclined guide surface 323, and the second mating end 322 has a second inclined guide surface 324. The first and second inclined guide surfaces 323 and 324 face opposite directions. When assembling the locking assembly 30, the limiting rod 32 passes through the adjustment holes 313 of the two guide portions 312 simultaneously. The first mating end 321 extends out from the through hole of one guide portion 312, and the second mating end 322 extends out from the through hole of the other guide portion 312. The limiting post 34 is disposed in the adjustment space 314 and mounted on the limiting rod 32. One end of the return spring 33 abuts against the limiting rod 32 at a position away from the first mating end 321, and the other end of the return spring 33 abuts against the side of the guide portion 312 away from the first mating end 321.

[0028] When the locking assembly 30 is installed on the heat dissipation housing 10, the upper end face of the heat-conducting plate 31 facing away from the guide portion 312 is in contact with the top wall of the receiving groove 111. The screw passes through the main body 311 of the heat-conducting plate 31 and is installed on the heat dissipation housing 10. The locking assemblies 30 of different groups are evenly distributed around the positioning post 114. The first mating end 321 is located near the positioning post 114, and the second mating end 322 is located near the side wall of the receiving groove 111. The first inclined guide surface 323 on the first mating end 321 is inclined downward, and the second inclined guide surface 324 on the second mating end 322 is inclined upward. The first inclined guide surfaces 323 on the different locking assemblies 30 enclose a mating space that gradually narrows upward. The bottom surface of the limiting rod 32 is flush with the bottom wall of the locking groove 113.

[0029] The lampshade 20 includes a main body 21 and a connecting portion 22 vertically connected to the upper surface of the main body 21. The connecting portion 22 is annularly arranged and has several through holes 221 and several positioning grooves 222. The through holes 221 penetrate the connecting portion 22 horizontally and are evenly spaced around the central axis of the lampshade 20, with the openings of the through holes facing the central axis of the lampshade 20. The positioning grooves 222 are provided on the outer peripheral surface of the connecting portion 22 and extend downward from the upper surface of the connecting portion 22. The positioning grooves 222 are also evenly spaced around the central axis of the lampshade 20. A waterproof surface 211 is formed on the upper surface of the main body 21 surrounding the connecting portion 22. A mounting groove 212 is provided in the middle of the bottom of the lampshade 20, and the middle of the mounting groove 212 further penetrates upward to form a through hole 213.

[0030] The fastener 50 includes a bottom cap 51 and a connector 52. The connector 52 is vertically connected to the bottom cap 51. The outer diameter of the bottom cap 51 is larger than the outer diameter of the connector 52. The connector 52 has an inwardly extending mounting hole 521 at the middle of the end away from the bottom cap 51. The wall of the mounting hole 521 has an internal thread. In addition, the outer periphery of the end of the connector 52 away from the bottom cap 51 has a conical extrusion surface 522. The outer diameter of the connector 52 at the position of the extrusion surface 522 gradually shrinks from the direction away from the bottom cap 51.

[0031] In addition, the present invention also includes a first sealing ring 60 and a second sealing ring 70, both of which are arranged in annular shape. The shape of the first sealing ring 60 corresponds to the shape of the first waterproof groove 115, and the shape of the second sealing ring 70 corresponds to the shape of the connector 52.

[0032] During assembly, the first sealing ring 60 is installed on the first waterproof groove 115 and extends out from the first waterproof groove 115. The second sealing ring 70 is sleeved on the connector 52. The connecting part 22 of the lampshade 20 is embedded into the receiving groove 111 of the heat dissipation housing 10. The positioning post 114 of the heat dissipation housing 10 corresponds one-to-one with the positioning groove 222 on the lampshade 20. The positioning post 114 is engaged with the positioning groove 222. Through the cooperation of the positioning post 114 and the positioning groove 222, the installation position of the lampshade 20 on the heat dissipation housing 10 is accurate, and the slot 113 on the heat dissipation housing 10 can be aligned with the through hole 221 in subsequent installation. The first sealing ring 60 is sandwiched between the waterproof surface 211 of the lampshade 20 and the bottom edge of the main body 11. The mating space and the through hole 213 are aligned with each other in the vertical direction. In the initial state, under the action of the first sealing ring 60, there is a height difference between the through hole 221 and the slot 113 in the vertical direction. The position of the through hole 221 is lower than that of the slot 113.

[0033] Next, the fastener 50 is installed on the heat sink housing 10. During installation, the fastener 50 passes through the mounting groove 212 and the through hole 213. The internal thread of the fastener 50 is engaged with the external thread of the connecting post 112. The fastener 50 is rotated in the direction of tightening the fastener 50, so that the pressing surface 522 of the fastener 50 extends into the mating space and presses the first inclined guide surface 323 of all the limiting rods 32. Under the cooperation of the pressing surface 522 and the first inclined guide surface 323, the limiting rods 32 move outward, and the limiting post 34 presses the return spring 33, causing the return spring 33 to elastically contract. During the outward movement of the limiting rod 32, the second inclined guide surface 324 presses upward against the hole wall of the through hole 221, causing the lamp cover 20 to move upward. The second mating end 322 of the limiting rod 32 is inserted into the slot 113, and the waterproof surface 211 of the lamp cover 20 presses against the first sealing ring 60. The second sealing ring 70 is clamped between the bottom cap 51 and the top wall of the mounting groove 212.

[0034] Conversely, when the lamp cover 20 is removed from the heat sink housing 10 to replace the lamp board 40, the fixing member 50 is rotated in the opposite direction to remove the fixing member 50 from the connecting post 112. The return spring 33 pushes the limiting rod 32 back to its original position by squeezing the limiting post 34 until the limiting post 34 abuts against the guide part 312. The second mating end 322 of the limiting rod 32 then exits from the slot 113, thereby releasing the limitation on the lamp cover 20. Then the lamp cover 20 can be removed from the heat sink housing 10.

[0035] The beneficial effects of the quick-release LED explosion-proof light of the present invention are as follows: By setting several sets of locking components 30 and fixing parts 50, the locking components 30 are provided with limiting rods 32 and return springs 33 that push the limiting rods 32 back to their original positions. The limiting rods 32 are provided with a first mating end 321 with a first inclined guide surface 323. The first inclined guide surfaces 323 on different locking components 30 enclose a mating space that gradually shrinks upwards. The fixing parts 50 are provided with a conical pressing surface 522. When the fixing parts 50 are installed, the pressing surface 522 of the fixing parts 50 presses the first inclined guide surface 323 of the limiting rods 32, so that the limiting rods 32 pass through the lamp cover 20 and are installed on the heat dissipation housing 10, thereby completing the installation and fixing of the lamp cover 20. When the fixing parts 50 are removed, the limiting rods 32 are removed from the heat dissipation housing 10 and the lamp cover 20, thereby releasing the limiting of the lamp cover 20. The entire disassembly and assembly process is convenient and quick, effectively saving maintenance time and is highly practical.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
