Description

Technical Field

[0001] This utility model relates to the field of explosion-proof lamp technology, and in particular to an explosion-proof lamp that is easy to maintain. Background Technology

[0002] Explosion-proof lamps are used in hazardous locations where flammable gases and dust may be present. They are designed to prevent the ignition of flammable gases and dust in the surrounding environment by electric arcs, sparks, and high temperatures that may be generated inside the lamp, thus meeting explosion-proof requirements. Based on the bulb type, explosion-proof lamps are mainly classified as explosion-proof incandescent lamps, explosion-proof high-pressure mercury lamps, explosion-proof low-pressure fluorescent lamps, and LED explosion-proof lamps. Currently, the structure of explosion-proof lamps mainly includes a lamp housing, a bulb housed within the housing, and a lamp cover at the front of the housing. The lamp housing is made of lightweight die-cast aluminum alloy, and the surface is treated with high-pressure electrostatic powder coating to achieve a certain level of explosion-proof performance.

[0003] The prior art can be referenced in Chinese Patent Application No. 202322032716.7, which discloses an explosion-proof lamp that is easy to maintain. It includes an adjustment mechanism, on the surface of which an explosion-proof lamp mechanism is threadedly connected. A protective cover is fixedly connected to the surface of the explosion-proof lamp mechanism. The adjustment mechanism includes an adjustment component, which is threadedly connected to the surface of the explosion-proof lamp mechanism. A receiving column is hinged to the surface of the adjustment component. A rotating ball is movably connected to the surface of the receiving column. A support column is fixedly connected to one end of the rotating ball. A base is fixedly connected to one end of the support column. However, the lamp cover and the adjustment mechanism of this explosion-proof lamp are connected by threads, and disassembly requires rotation, which is time-consuming and cannot achieve effective heat dissipation and quick disassembly and maintenance of the explosion-proof lamp.

[0004] Therefore, an explosion-proof light that is easy to maintain is provided. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1, referring to Figure 1-5 An explosion-proof lamp that is easy to maintain includes a lamp housing 1, a mounting bracket on the upper surface of the lamp housing 1, a heat dissipation structure connected to the top of the lamp housing 1 and inside the mounting bracket, a light source module installed inside the lamp housing 1 through a positioning structure, a lamp cover 8 at the bottom of the lamp housing 1, a snap-fit ​​structure between the lamp cover 8 and the lamp housing 1, and a switch on the upper surface of the lamp housing 1.

[0026] The heat dissipation structure includes a rectangular frame 2 connected to the upper end of the lamp housing 1 by a screw bolt 4. Heat dissipation fins 3 are fixed at equal intervals on the inner wall of the rectangular frame 2, and a cooling fan 7 is fixed to the upper end of the heat dissipation fins 3.

[0027] The mounting bracket includes two connecting blocks 5 fixed on both sides of the upper end face of the lamp housing 1. The two connecting blocks 5 are connected to a U-shaped connecting rod 6 by bolts and nuts.

[0028] A fixing hole is provided on the horizontal end of the U-shaped connecting rod 6. The U-shaped connecting rod 6 can be fixed in the installation position by passing a bolt through the fixing hole, so as to realize the installation of the explosion-proof lamp.

[0029] The light source module includes a lamp board 11, on which LED beads 12 are integrated and installed.

[0030] The positioning structure includes four positioning rods 10 fixed at the four corners of the top of the inner wall of the lamp body shell 1. A rectangular support ring 13 is slidably sleeved on the four positioning rods 10. A first magnet block 17 is fixed in the middle of the four sides of the rectangular support ring 13. A second magnet block 18 is fixed in the middle of the four inner walls of the lamp body shell 1, which respectively forms an adsorption engagement with the four first magnet blocks 17.

[0031] The size of the lamp plate 11 is larger than the inner hole size of the rectangular support ring 13, and the lamp plate 11 is located above the rectangular support ring 13.

[0032] By placing the lamp panel 11 inside the lamp housing 1 and fitting the rectangular support ring 13 onto the four positioning rods 10, the lamp panel 11 can be fixed after the first magnet block 17 and the second magnet block 18 form an attraction. The lamp panel 11 can also better transfer heat to the lamp housing 1. When disassembly and maintenance are required, the rectangular support ring 13 can be directly pulled off the positioning rods 10, so that the first magnet block 17 and the second magnet block 18 are separated. The lamp panel 11 is then freed from its restraints and can be maintained or replaced.

[0033] By pressing the switch, the lamp board 11 and the cooling fan 7 can be powered on. The heat generated by the LED beads 12 is transferred to the lamp housing 1 and the heat sink 3. The cooling fan 7 blows cool air from the outside onto the heat sink 3 and the lamp housing 1, thereby achieving heat dissipation. When it is necessary to clean the cooling fan 7 and the heat sink 3, simply unscrew the horn bolts 4 manually to remove the rectangular frame 2, the heat sink 3 and the cooling fan 7 without tools.

[0034] Example 2 is an optimization based on Example 1, specifically:

[0035] The snap-fit ​​structure includes a rectangular snap ring 16 disposed on the upper side of the lampshade 8. The rectangular snap ring 16 forms an insertion fit with the inner wall of the lamp body shell 1. Each of the four outer sides of the rectangular snap ring 16 is provided with a snap block 14. Each of the four inner walls of the lamp body shell 1 is provided with a snap groove 9 that forms a snap fit with the snap block 14. The upper side of the lampshade 8 is provided with a prying snap hole 15.

[0036] The rectangular retaining ring 16 on the lampshade 8 is directly inserted into the inner wall of the lamp body shell 1, so that the retaining block 14 engages with the retaining groove 9, allowing the lampshade 8 to be installed quickly. When disassembly is required, simply pry open the prying latch 15 on the lampshade 8 manually, and then the retaining block 14 will disengage from the retaining groove 9, allowing the lampshade 8 to be removed. It is convenient and quick, and no tools are required.

[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
