DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1 - Figure 2 The utility model provides an explosion-proof lamp for mining, including a mounting frame 1, a protective mechanism 3 is arranged at one end of the bottom of the mounting frame 1, a lamp assembly 4 is arranged on the inner side of the protective mechanism 3, the protective mechanism 3 includes a sleeve 31, the sleeve 31 is sleeved on the outer side of the lamp assembly 4 and is fixedly connected to the bottom of the mounting frame 1, a protective mesh cover 33 for protecting the lamp assembly 4 is arranged at the bottom of the sleeve 31, plug-ins 34 are arranged at both ends of the top of the protective mesh cover 33, and the two plug-ins 34 are slidably matched with the sleeve 31, and limiters 35 for limiting the separation of the plug-ins 34 from the sleeve 31 are arranged at both ends of the top of the sleeve 31, a cleaning piece 36 for cleaning the lamp assembly 4 is arranged at one end of the inner side of the protective mesh cover 33, and a driving assembly 5 for driving the lamp assembly 4 to rotate is arranged at one end of the mounting frame 1.

[0029] When installing the protective mesh cover 33, the two connectors 34 at the top of the protective mesh cover 33 are directly slidably engaged with the sleeve 31, and then the connectors 34 are restricted by the limiter 35 so that they cannot be separated from the sleeve 31. This allows the protective mesh cover 33 to remain fixed to the sleeve 31, thereby achieving the installation of the protective mesh cover 33. Similarly, the protective mesh cover 33 can be removed by releasing the restriction on the connector 34 through the limiter 35, thereby achieving quick disassembly and assembly of the protective mesh cover 33, and then the protective mesh cover 33 can be easily removed for cleaning, thereby avoiding excessive dust on the protective mesh cover 33 that is easy to float away and affect the lighting effect of the lamp assembly 4.

[0030] Reference Figure 3The connector 34 includes a limit block 341, which is fixedly connected to one end of the top of the protective net cover 33. The top of the limit block 341 is fixedly connected with an insertion rod 342, which passes through the outer edge of the sleeve 31 and extends to the top of the sleeve 31. The top of the insertion rod 342 is provided with a penetrating pin hole 343.

[0031] Reference Figure 4 The limiting member 35 includes a fixing plate 351 and a stopper 353. The fixing plate 351 is fixedly connected to the outer edge of the top of the sleeve 31. A vertically penetrating pin 352 is slidably connected to the middle of the fixing plate 351. One end of the pin 352 is slidably matched with the pin hole 343 of the corresponding plug rod 342. The other end of the pin 352 is fixedly connected to a pull block 354. The stopper 353 is fixedly connected to the middle of the plug rod 342. A spring 355 is sleeved on the plug rod 342. One end of the spring 355 abuts against the stopper 353, and the other end of the spring 355 abuts against the fixing plate 351.

[0032] The installation process of the protective net cover 33 is as follows: by pulling the pull block 354 outward, the latch pin 352 slides outward, which also causes the stopper 353 to slide outward, until the stopper 353 completely squeezes the spring 1 355 and cannot move further. At this time, the spring 1 355 is squeezed to accumulate elastic potential energy, and at the same time, the positions of the insertion points of the latch pin 352 and the insertion rod 342 on the sleeve 31 are staggered. Then, the insertion rod 342 at the top of the protective net cover 33 is inserted into the sleeve 31, and finally the pull block 354 is released. At this time, the spring 1 355 releases potential energy, so that the stopper 353 drives the latch pin 352 to slide in the opposite direction, which makes the latch pin 352 cooperate with the pin hole 343 of the insertion rod 342, so that the insertion rod 342 can be restricted from being separated from the sleeve 31, thereby completing the installation of the protective net cover 33.

[0033] Similarly, during disassembly, the pull block 354 is pulled outward to make the pin 352 slide outward until the pin 352 is completely disengaged from the pin hole 343. At this time, the insertion rod 342 is no longer restricted by the pin 352, so the protective mesh cover 33 can be pulled downward for removal. The entire disassembly and assembly process is very convenient, so that the protective mesh cover 33 can be easily removed for cleaning, avoiding excessive dust on the protective mesh cover 33 that is easily scattered and affects the lighting effect of the lamp assembly 4.

[0034] Reference Figure 5 The lamp assembly 4 includes a lamp holder 41, which is arranged on the inner side of the sleeve 31 and rotatably connected to the inner wall of the sleeve 31. The bottom of the lamp holder 41 is fixedly connected to a lamp body 42, the top of the sleeve 31 is fixedly connected to a connecting rod 43, and the top of the connecting rod 43 is fixedly connected to a connecting plate 44.

[0035] Reference Figure 6The driving assembly 5 includes a motor 51, which is fixedly mounted at one end of the top of the mounting frame 1. The output shaft of the motor 51 is fixedly connected to a connecting plate 2 52. The outer edge of the connecting plate 2 52 is threadedly connected to a plurality of connecting bolts 53. The plurality of connecting bolts 53 are distributed at equal angles around the connecting plate 2 52. The connecting plate 1 44 is fixedly connected to the connecting plate 2 52 through the connecting bolts 53. The outer edge of the connecting plate 1 44 is provided with a plurality of threaded holes corresponding to the connecting bolts 53. The plurality of connecting bolts 53 are threadedly matched with the corresponding threaded holes.

[0036] Reference Figure 7 The cleaning member 36 includes a sleeve 361 and a slider 364. One end of the sleeve 361 is fixedly connected to the inner wall of the protective net cover 33. The other end of the sleeve 361 is slidably connected to a sleeve rod 362. The sleeve rod 362 penetrates the side wall of the sleeve 361 and extends to the outside of the sleeve 361. One end of the sleeve rod 362 is fixedly connected to a cleaning plate 363. The cleaning plate 363 can contact the outer wall of the lamp body 42. The slider 364 is slidably connected to the inner side of the sleeve 361 and fixedly connected to the other end of the sleeve 361. A spring 2 365 is placed inside the sleeve 361. One end of the spring 2 365 is in contact with the bottom of the slider 364, and the other end of the spring 2 365 is in contact with the inner wall of the sleeve 361. The spring 2 365 can act on the slider 364 to make it slide outward, which makes the sleeve rod 362 slide outward and act on the cleaning plate 363, so that the cleaning plate 363 is always in close contact with the lamp body 42.

[0037] The working principle of the utility model is as follows: when there is too much dust on the outer wall of the lamp body 42, the motor 51 is started to rotate the connecting plate 2 52, which causes the connecting plate 1 44 to rotate synchronously, and the connecting rod 43 drives the sleeve 31 to rotate, thereby causing the sleeve 31 to drive the lamp body 42 to rotate. Since the cleaning plate 363 is in contact with the outer wall of the lamp body 42, the lamp body 42 will slide and rub against the cleaning plate 363 when it rotates, so that the cleaning plate 363 cleans the dust attached to the outer wall of the lamp body 42, thereby avoiding the problem of poor lighting effect caused by excessive dust accumulation on the outer wall of the lamp body 42.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
