[0024] The explosion-proof lamp provided by the utility model is convenient for replacing the photoelectric module. Figures 1 to 5As shown: An explosion-proof lamp with easy replacement of photoelectric modules, including a mounting shell 1, a lamp holder 2 and a lamp body 3. The lamp body 3 is fixedly mounted on the bottom end of the lamp holder 2. The lamp body 3 movably passes through the mounting hole opened in the mounting shell 1, and a disassembly mechanism 4 is provided between the lamp holder 2 and the mounting shell 1.

[0025] The disassembly and assembly mechanism 4 includes a positioning block 401 and an L-shaped clamping plate 406. The positioning block 401 is fixedly installed on the top of the mounting shell 1. A positioning groove 402 is provided on the outer wall of the mounting shell 1. The positioning block 401 is clamped in the positioning groove 402. The top of the positioning block 401 is rotatably connected to the limit plate 404. A clamping groove 405 is provided on the top of the limit plate 404. The L-shaped clamping plate 406 is clamped in the clamping groove 405. A rotating groove 407 is provided on the outer wall of the mounting shell 1. An axis hole 410 is provided near the bottom end of the L-shaped clamping plate 406. A connecting shaft 408 is fixedly installed on the inner wall of the rotating groove 407. The connecting shaft 408 movably passes through the axis hole 410, and a torsion spring 409 is fixedly connected between the outer wall of the connecting shaft 408 and the inner wall of the axis hole 410.

[0026] Specifically, in the above technical solution, when the lamp body 3 needs to be replaced, the L-shaped card plate 406 can be moved outward to rotate the L-shaped card plate 406 outward, and the torsion spring 409 can be twisted to disengage the L-shaped card plate 406 from the card slot 1 405, so that the L-shaped card plate 406 no longer limits the limit plate 404, and then the limit plate 404 is rotated to rotate the limit plate 404 90 degrees, so that the limit plate 404 no longer limits the lamp holder 2, and then the lamp holder 2 is pulled upward to disengage the positioning block 401 from the positioning slot 402, and the lamp holder 2 drives the lamp body 3 to move upward to disengage the lamp body 3 from the mounting shell 1, completing the disassembly, and then the new lamp body 3 can be inserted into the mounting shell 1, so that the positioning block 401 is stuck in the positioning slot 402, and then Then rotate the limit plate 404 90 degrees, and then loosen the L-shaped clamping plate 406. At this time, the L-shaped clamping plate 406 will reset and rotate under the reset force of the torsion spring 409, so that the L-shaped clamping plate 406 is stuck in the slot again, and then the installation of the new lamp body 3 is completed. The above structure can facilitate personnel to maintain and replace the lamp body 3, thereby improving the work efficiency of personnel, and solving the problem that the installation between the existing explosion-proof lamp head 2 and the mounting shell 1 is achieved by using multiple bolts, resulting in personnel needing specific wrench tools to remove or install the bolts one by one when they need to maintain and replace the lamp body 3 under the lamp head 2, which has low work efficiency and is easy to lose the bolts, affecting the normal installation and use of the explosion-proof lamp.

[0027] Furthermore, the top of the positioning block 401 is rotatably connected to a rotating shaft 403 via a bearing, and a limiting plate 404 is fixedly mounted on the top of the rotating shaft 403;

[0028] The rotation shaft 403 is provided so that the limiting plate 404 can be rotated by the rotation shaft 403 .

[0029] Furthermore, the L-shaped card plate 406 is adapted to the card slot 1 405, and the positioning block 401 is adapted to the positioning slot 402;

[0030] Among them, by providing an L-shaped card plate 406, the L-shaped card plate 406 can be inserted into the card slot 1 405, thereby limiting the limiting plate 404.

[0031] Furthermore, a fixing ring 6 is connected to the bottom end of the mounting shell 1, a lampshade 7 is fixedly mounted on the bottom end of the fixing ring 6, a protective frame 8 is sleeved on the outside of the lampshade 7, and the protective frame 8 is fixedly mounted on the bottom end of the fixing ring 6, and a connecting mechanism 5 is provided between the fixing ring 6 and the mounting shell 1;

[0032] The protection frame 8 can provide good protection for the lampshade 7 and the lamp body 3 . Example 2

[0033] On the basis of the first embodiment, the explosion-proof lamp provided by the present invention is convenient for replacing the photoelectric module.

The frame-shaped card plate 501 is clamped in the second card groove 508, and the frame-shaped card plate 501 is slidably connected to the inner wall of the contraction groove 502.

[0034] Specifically, when the lampshade 7 needs to be cleaned or replaced, the frame-shaped card plate 501 can be directly pulled outward, and the frame-shaped card plate 501 drives the slider 504 to compress the spring 506. When the frame-shaped card plate 501 moves outward, it disengages from the second card slot 508, so that the frame-shaped card plate 501 no longer limits the fixing ring 6. At this time, the fixing ring 6 can be downwardly separated from the mounting shell 1, thereby completing the removal of the lampshade 7. When the lampshade 7 needs to be installed again, the fixing ring 6 and the mounting shell 1 are separated. The bottom ends are in contact, so that the second card slot 508 is aligned with the groove 507, and then the frame card plate 501 is released. At this time, the slider 504 will drive the frame card plate 501 to be clamped into the second card slot 508 under the restoring force of the spring 506, thereby completing the installation of the lampshade 7. Through the above structure, it is convenient for personnel to disassemble and assemble the lampshade 7, so as to facilitate personnel to clean and replace it, ensure the light transmittance of the lampshade 7, and ensure the protective effect of the lampshade 7 and the protective frame 8 on the lamp body 3. The structure is simple and practical.

[0035] Furthermore, a slider 504 is fixedly installed on the top of the frame-shaped card plate 501, a slide groove 503 is opened on the top of the inner wall of the contraction groove 502, the slider 504 is slidably connected to the slide groove 503, and a limit rod 509 is fixedly installed on the inner wall of the slide groove 503.
