[0028] The moving assembly 200 includes a rotating seat 201 arranged on the side of the light strip circuit board 104 away from the light strip housing 103, the rotating seat 201 is symmetrically fixedly installed on the side of the light strip circuit board 104, a first rotating shaft 202 is rotatably installed on one side of the rotating seat 201, two first rotating rods 203 are rotatably installed on the outer wall of the first rotating shaft 202, the two first rotating rods 203 are cross-arranged, and the second rotating shaft 205 is installed at the intersection of the two second rotating rods 204, the second rotating rods 204 are rotatably installed on one end of the first rotating rod 203 away from the first rotating shaft 202, the two second rotating rods 204 are cross-arranged, and the intersection is the center point of the second rotating rod 204, and the other end of the second rotating rod 204 is provided with a driving assembly 300; by setting the moving assembly 200, when it is necessary to disassemble the light strip housing 103, clean it and align the light strip circuit board 104 During maintenance, the light strip circuit board 104 can be moved, so that the light strip circuit board 104 drives the rotating seat 201 to move, and the rotating seat 201 drives the first rotating shaft 202 to move, and the first rotating shaft 202 drives one end of the first rotating rod 203 to rotate, so that the other end of the first rotating rod 203 drives one end of the second rotating rod 204 to rotate, and the second rotating rod 204 rotates around the second rotating shaft 205 as the axis, avoiding working in heavy oil pollution environments such as factories and gas stations. Thick oil pollution is easily adhered to the surface of the lamp, which affects the lighting effect and heat dissipation effect of the LED explosion-proof floodlight, and requires frequent disassembly of the lamp housing, cleaning of the lamp housing, and inspection and maintenance of the light strip, which causes cumbersome operation. The light strip circuit board 104 can be slid to one side of the light strip frame 102, which is convenient for maintenance personnel to inspect and maintain the light strip circuit board 104.

[0029] See also Figure 3-4As shown, the driving assembly 300 includes a driving block 301 arranged at one end of the second rotating rod 204, and a fixed block 302 is slidably installed at the end of the driving block 301 away from the second rotating rod 204, and a fixed plate 303 is fixedly installed on one side of the fixed block 302, and the fixed plate 303 is fixedly installed on one side of the light strip frame 102. A guide assembly 400 for controlling the moving trajectory of the light strip circuit board 104 is arranged on one side of the fixed plate 303, and the driving block 301 and the fixed block 302 are connected by a spring 304; by setting the driving assembly 300, when it is necessary to disassemble the light strip housing 103 for cleaning and maintenance of the light strip circuit board 104, the spring 304 releases its elastic potential energy, and elastic deformation occurs to push the driving block 301 to move away from the spring 304. The driving block 301 drives one end of the second rotating rod 204 to move, thereby pushing the light strip circuit board 104 to move away from the light strip frame 102 through the second rotating rod 204, the first rotating rod 203, the first rotating shaft 202 and the rotating seat 201, avoiding working in heavy oil pollution environments such as factories and gas stations. The surface of the lamp is prone to thick oil pollution, which affects the lighting and heat dissipation effects of the LED explosion-proof floodlight, and requires frequent disassembly of the lamp housing, cleaning of the lamp housing, and inspection and maintenance of the light strip, which causes cumbersome operations. The moving component 200 can automatically push out the light strip circuit board 104 while disassembling the light strip housing 103, reducing the operating steps of maintenance personnel and making maintenance work simpler and faster.

[0030] See also Figure 3-4 As shown, a slide rail 305 is slidably installed on the peripheral side of the driving block 301, and the slide rail 305 is fixedly installed on one side of the fixed plate 303; it can guide the movement of the driving block 301, avoiding the problem that the driving block 301 is easily offset or one end is lifted during movement, which affects the moving component 200 to push the light strip circuit board 104 out, making the device more stable.

[0031] Embodiment 2

[0032] See also Figure 3As shown, compared with Example 1, as another implementation of the utility model, the guide component 400 includes a circular hole 401 arranged on one side of the fixed plate 303, the circular hole 401 is opened on one side of the fixed plate 303, and a guide round rod 402 is slidably installed on the inner wall of the circular hole 401, and one end of the guide round rod 402 is fixedly installed on one side of the light strip circuit board 104; by setting the guide component 400, when the moving component 200 pushes the light strip circuit board 104, the light strip circuit board 104 drives the guide round rod 402 to move, so that the circular hole 401 limits the moving trajectory of the guide round rod 402, avoiding that when the light strip frame 102 adjusts the angle through the angle adjustment plate 101, the light strip circuit board 104 is easy to rotate when it moves, thereby causing the light strip circuit board 104 to abut against the light strip frame 102, causing motion interference, and hindering the movement of the light strip circuit board 104, thereby improving the stability and reliability of the equipment. In addition, it can also share the load of the moving component 200, reduce the loss of the moving component 200, and thus improve the service life of the equipment.

[0033] See also Figure 3 As shown, the distance between the two ends of the guide rod 402 is greater than the sum of the distance between the two ends of the second rotating rod 204 and the distance between the two ends of the first rotating rod 203. In this way, when the spring 304 reaches the maximum length, the guide rod 402 can still slide on the inner wall of the circular hole 401, avoiding the problem that when the distance between the two ends of the guide rod 402 is short, the guide rod 402 is easily moved out of the inner wall of the circular hole 401, thereby stopping the guiding function of the light strip circuit board 104, and improving the stability of the light strip circuit board 104 when moving.

[0034] See also Figure 3 As shown, a first limit plate 403 is fixedly installed at one end of the guide rod 402 away from the light strip circuit board 104, and the radius of the first limit plate 403 is greater than the radius of the circular hole 401; the light strip frame 102 can adjust the inclination angle through the angle adjustment plate 101, so that when the light strip frame 102 tilts downward, the first limit plate 403 can abut against the fixed plate 303 to prevent the guide rod 402 from moving outside the inner wall of the circular hole 401, avoiding that when the light strip frame 102 adjusts the inclination angle through the angle adjustment plate 101 so that the light strip frame 102 tilts downward, the light strip circuit board 104 continues to move under the action of gravity after being pushed out by the moving component 200, which easily drives the guide rod 402 to move to one side of the circular hole 401, causing the guide rod 402 to stop guiding the light strip circuit board 104, thereby causing the guide rod 402 and the light strip circuit board 104 to produce motion interference, thereby improving the stability and reliability of the equipment.

[0035] See also Figure 3As shown, a second limit plate 404 is slidably installed on one side of the fixed plate 303 close to the light strip circuit board 104, and the second limit plate 404 is fixedly installed on the outer wall of the guide round rod 402; when the light strip housing 103 is installed, the light strip housing 103 drives the light strip circuit board 104 to move, the light strip circuit board 104 drives the guide round rod 402 to move, and the guide round rod 402 drives the second limit plate 404 to move, so that when the light strip circuit board 104 moves to fit with the light strip circuit board 104, the second limit plate 404 abuts against the fixed plate 303, avoiding the light strip circuit board 104 from moving a long distance when the light strip housing 103 is installed, resulting in a gap between the light strip circuit board 104 and the light strip frame 102, so that oil particles and dust in the air fall on one side of the light strip circuit board 104, causing pollution to the LED light strip, thereby reducing the heat dissipation performance and lighting performance of the LED light strip, reducing the impact of the environment on the LED light strip, thereby improving the heat dissipation performance and lighting performance of the LED light strip.

[0036] See also Figure 1-3 As shown, finger holes 500 are provided on both sides of the light strip housing 103; when removing the light strip housing 103, the maintenance personnel can put their fingers into the inner wall of the finger holes 500 to increase the friction between the fingers and the light strip housing 103, thereby avoiding the surface of the light strip housing 103 being easily adhered to oil in a heavy oil environment, making it difficult for the maintenance personnel to remove the light strip housing 103, and making the removal of the light strip housing 103 simpler and faster.

[0037] See also Figure 2-3 As shown, a positioning block 600 is symmetrically fixedly installed on one side of the light strip circuit board 104 close to the light strip housing 103, and a positioning groove 601 is symmetrically opened on one side of the light strip housing 103 close to the light strip circuit board 104, and the positioning block 600 is slidably installed on the inner wall of the positioning groove 601; when installing the light strip housing 103, by making the positioning block 600 abut against the inner wall of the positioning groove 601, it is convenient to align the light strip housing 103 with the light strip circuit board 104, avoiding the problem that the light strip housing 103 is difficult to align with the light strip circuit board 104 when directly pushing the light strip housing 103 to reset the light strip circuit board 104, resulting in the need for repeated sliding alignment when the light strip housing 103 abuts against the light strip frame 102, which is cumbersome to operate and easily causes additional wear, making the installation of the light strip housing 103 and the resetting of the light strip circuit board 104 more convenient and quick.

[0038] See also Figure 2As shown, LED lamp holders are evenly arranged on one side of the light strip circuit board 104, and the distance between the two ends of the LED lamp holders is smaller than the distance between the two ends of the positioning block 600; when the positioning block 600 abuts against the positioning groove 601, one side of the light strip housing 103 will not contact the LED light strip, thereby avoiding the problem that when the light strip housing 103 is pushed to reset the light strip circuit board 104, one side of the light strip housing 103 abuts against the LED light strip, which easily causes the LED light strip to break, thereby improving the stability and reliability of the equipment.

[0039] Working principle: When it is necessary to clean the light strip housing 103 and inspect and maintain the light strip circuit board 104, the maintenance personnel disconnect the power supply, place their fingers on the inner wall of the finger hole 500, and pull the light strip housing 103 to move away from the light strip frame 102. At this time, the spring 304 releases its elastic properties and undergoes elastic deformation, pushing the drive block 301 to move along the slide rail 305 in the direction away from the fixed block 302. The drive block 301 drives one end of the second rotating rod 204 to move, so that the second rotating rod 204 rotates around the second rotating shaft 205 as the axis. , the other end of the second rotating rod 204 drives the first rotating rod 203 to rotate, so that the end of the first rotating rod 203 close to the first rotating shaft 202 drives the first rotating shaft 202 to move in the direction close to the light strip circuit board 104, the first rotating shaft 202 drives the rotating seat 201 to move, the rotating seat 201 drives the light strip circuit board 104 to move, the light strip circuit board 104 drives the guide round rod 402 to move, and the guide round rod 402 moves in a direction perpendicular to the fixed plate 303 under the limiting action of the round hole 401, thereby limiting the moving trajectory of the light strip circuit board 104;

[0040] After cleaning the light strip housing 103 and inspecting and maintaining the light strip circuit board 104, move the light strip housing 103 so that the positioning groove 601 abuts against the positioning block 600. At this time, push the light strip housing 103, the light strip housing 103 drives the positioning block 600 to move, the positioning block 600 drives the light strip circuit board 104 to move, the light strip circuit board 104 drives the moving component 200 and the driving component 300 to reset, and at the same time, the light strip circuit board 104 drives the guide round rod 402 to move, and the guide round rod 402 drives the second limiting plate 404 to move. When the second limiting plate 404 abuts against the fixed plate 303, the light strip circuit board 104 fits with the light strip frame 102, completing the installation of the light strip housing 103 and the resetting of the light strip circuit board 104. At this time, you can connect the power supply and start working.
