[0031] Reference example Figures 1 to 4 An explosion-proof LED lighting lamp includes a housing 1, a first bracket 2 fixed to the back of the housing 1, and a fixing frame 3. The first bracket 2 is provided with a rotatable and adjustable second bracket 4. The second bracket 4 is provided with a connecting post 41. The connecting post 41 is provided with a plurality of equally spaced limiting parts 42 evenly distributed around a dot as the axis. The curved surface of the connecting post 41 is provided with a fixing groove 43 and is disposed between the limiting parts 42. The fixing frame 3 is provided with a first through hole 31 for the connecting post 41 to pass through. The first through hole 31 is provided with a second through hole 32 for the limiting parts 42 to pass through. The first through hole 31 is provided with retractable fixing blocks 5 on both sides. The back sides of the fixing blocks 5 are provided with springs 6, which act on the fixing frame 3 to make the fixing blocks 5 embed into the fixing grooves 43. One end of the fixing block 5 is provided with an inclined surface 51 for the connecting post 41 to push the fixing block 5 inward. The fixing frame 3 is provided with a magnet 7 and is magnetically attracted to the fixing blocks 5.

[0032] It is worth mentioning that one end of the fixing frame 3 is provided with a cavity 33 for accommodating the fixing block 5. The cavity 33 is provided with a notch 34 for the fixing block 5 to pass through. Limiting grooves 35 are provided on both sides of the cavity 33. Mounting parts 55 are provided on both sides of the fixing frame 3. Mounting parts 55 are provided with mounting holes 56. The limiting grooves 35 limit the distance of the fixing block 5. Fasteners are placed in the mounting holes 56 to connect and fix the mounting parts to the fixed object. The fixing frame 3 serves as a supporting component, providing convenience for the subsequent installation and replacement of the housing 1.

[0033] It is worth mentioning that the fixed block 5 has pressure bearing parts 52 on both sides and is slidably disposed in the limiting groove 35. The pressure bearing part 52 is provided with guide post 53 and passes through the cavity 33. An operating part 54 is provided between the two guide posts 53. A distance is left between the operating part 54 and the fixed frame 3 for the user to operate. The spring 6 is disposed on the outer wall of the guide post 53. The two ends of the spring 6 abut against the pressure bearing part 52 and the cavity 33 respectively. The pressure bearing part 52 not only plays the role of limiting, but also bears the elastic force of the spring 6 and transmits it to the fixed block 5. The guide post 53 prevents the fixed block 5 from leaving the cavity 33 and also prevents the spring 6 from leaving the pressure bearing part 52. The operating part 54 makes it convenient for the user to operate the fixed block 5 to leave the fixed groove 43.

[0034] It is worth mentioning that a top block 36 is provided in the cavity 33 and is arranged between the guide posts 53. The magnet 7 is arranged in the top block 36 and is located on the opposite side of the fixing block 5. When the fixing block 5 is squeezed inward by the connecting post 41, there is still a gap between the fixing block 5 and the magnet 7. Only through the operating part 54 can the fixing block 5 and the magnet 7 come into contact.

[0035] It is worth mentioning that the housing 1 is provided with a detachable end cover 8, which is connected and fixed to the first bracket 2. By removing the end cover 8, it is easy to connect the external power supply to the circuit board 11.

[0036] It is worth mentioning that the housing 1 is equipped with a circuit board 11, which has several LED lights 12. A transparent cover 13 is provided below the LED lights 12. The transparent cover 13 is glued to the side wall of the housing 1. An O-ring 14 is provided between one end of the transparent cover 13 and the housing 1. The LED light 12 source shines on the irradiated part through the transparent cover 13. The glue is epoxy resin glue, which is the first sealing measure. The O-ring 14 is the second sealing measure to prevent dust and flammable and explosive gases from seeping into the housing 1.

[0037] It is worth mentioning that a mesh cover 15 is provided below the transparent cover 13, and a pressure ring 16 is provided between the mesh cover 15 and the transparent cover 13. The pressure ring 16 fits against the inner wall of the housing 1, and the mesh cover 15 prevents small stones and parts from splashing and breaking the transparent cover 13.

[0038] It is worth mentioning that a conduit 17 is provided on one side of the housing 1. A sealing sleeve 171 and a gasket 172 are arranged in sequence inside the conduit 17. A clamping nut 173 is provided in the conduit 17 and abuts against the gasket 172. The external power cord enters the housing 1 through the conduit 17. After the wiring is completed, the clamping nut 173 is used to compress and deform the sealing sleeve 171 and make it stick tightly to the outer wall of the external power cord.

[0039] The working principle of this utility model is described as follows:

[0040] During installation, simply insert the connecting post 41 and the limiting part 42 into the first through hole 31 and the second through hole 32. The connecting post 41 causes the fixing block 5 to retract into the cavity 33 through the inclined surface 51. When the fixing groove 43 coincides with the notch 34, the spring 6 pushes the fixing block 5 to quickly enter the fixing groove 43, so that the first bracket 2 and the fixing frame 3 are connected and fixed, thus completing the quick installation.

[0041] During disassembly, the operator holds the housing 1 with one hand and pulls one of the operating parts 54 with the other hand to make the fixing block 5 leave the fixing groove 43 until the operating part 54 can no longer be pulled. At this time, the magnet 7 has been magnetically attracted to the fixing block 5. The same operation is then performed on the other operating part 54 to remove all the fixing blocks 5 from the fixing groove 43 and complete the separation operation. Apply a force greater than that of the fixing block 5 attracted by the magnet 7 to the operating part 54 to make the fixing block 5 detach from the attraction of the magnet 7, in preparation for the next installation.

[0042] The above design scheme enables the product to achieve the advantages of convenient disassembly and assembly, and quick replacement.

[0043] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
