Description

Technical Field

[0001] The present invention relates to the technical field of emergency lights, and particularly to an emergency light that is convenient for adjusting the irradiation angle. Background Art

[0002] An emergency light is a type of lamp that can effectively illuminate and display evacuation routes when the normal lighting power supply fails, or can continuously illuminate without interruption. It is widely used in public places and places where continuous lighting is required;

[0003] Currently, the following technical problems are found in existing emergency lights:

[0004] First, current emergency lights can only be adjusted up and down, and cannot adjust their left and right angles. As a result, the emergency lights cannot adjust the light source direction according to the actual situation, increasing shadows and dark areas, and causing key areas to not be fully illuminated.

[0005] Second, after the rotation assembly of the emergency light is set, it is prone to wear due to factors such as environmental temperature, etc. As a result, the angle adjustment function of the emergency light body is easily blocked, and it cannot flexibly point to the area that needs to be illuminated, resulting in a decrease in the lighting effect.

[0006] Third, for current emergency lights equipped with a safety exit light-transmitting plate, it is not convenient to clean the inner surface of the safety exit light-transmitting plate. When cleaning, it is necessary to perform cumbersome disassembly of the safety exit light-transmitting plate from the emergency light, resulting in a significant reduction in the cleaning efficiency of the safety exit light-transmitting plate.

Detailed implementation manners

[0032] The following further describes in detail the implementation manners of the present invention with reference to the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0033] Embodiment: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown in the figure, in view of the problems existing in the prior art, the present invention provides an emergency lighting lamp that is convenient for adjusting the irradiation angle, including a lighting lamp housing 21. A safety exit light-transmitting plate 51 is provided at the front end of the lighting lamp housing 21. Two emergency lamp bodies 24 are provided at the upper end of the lighting lamp housing 21. Rotating shafts 23 are provided at the lower ends of the two emergency lamp bodies 24. A battery pack and a PCB control board driving board are provided inside the lighting lamp housing 21. First bevel gears 25 are fixedly installed at the lower ends of the two rotating shafts 23. Three support plates 26 are fixedly installed on the inner wall of the lighting lamp housing 21. Second bevel gears 27 are rotatably installed on each support plate 26 through bearings. The two second bevel gears 27 on the left are meshed with the first bevel gear 25 on the left, and the second bevel gear 27 on the right is meshed with the first bevel gear 25 on the right. A rotating rod 11 is slidably arranged inside the lighting lamp housing 21. Three gear pin sleeves 12 are fixedly sleeved on the rotating rod 11. A first flat gear 13 is fixedly installed through the rotating rod 11. Each gear pin sleeve 12 is meshed with the second bevel gear 27. A threaded rod 33 is provided inside the lighting lamp housing 21. A second flat gear 31 is fixedly installed at the right end of the threaded rod 33. The second flat gear 31 is meshed with the first flat gear 13. A wiping plate 32 is connected to the threaded rod 33 through threads. Lubricating mechanisms are provided on both sides of the lighting lamp housing 21. The lubricating mechanism includes a lubricating oil box 41. An oil pipe 43 is provided on the lubricating oil box 41. An extrusion block 42 is provided inside the lubricating oil box 41. An L-shaped rod 44 is fixedly installed at the lower end of the extrusion block 42. The wiping plate 32 is located at the side end of the L-shaped rod 44. When the wiping plate 32 moves, it will contact the L-shaped rod 44. When the device is in use, the user can adjust the position of the emergency lamp body 24 on the device according to the use requirements. When it is necessary to separate and illuminate the positions on both sides with the two emergency lamp bodies 24 on the device, by moving the moving top block 15 on the rotating rod 11 and moving it to the position of the positioning plate 35, then through the slope on the moving top block 15, the positioning plate 35 is upwardly extruded, so that the positioning plate 35 is removed from the annular groove 14 opened on the rotating rod 11. At this time, the rotating rod 11 can be horizontally moved. During the movement, the two gear pin sleeves 12 on the left side of the rotating rod 11 will be inserted into the two second bevel gears 27 on the right side and be in a meshing state with the two second bevel gears 27. And at this time, the positioning plate 35 at the right end of the lighting lamp housing 21 will also fit with the middle annular groove 14 on the rotating rod 11 under the elastic force of the elastic piece 34. At this time, when the rotating rod 11 is rotated, the rotating rod 11 will drive the two gear pin sleeves 12 to rotate, and the two gear pin sleeves 12 will drive the two second bevel gears 27 to rotate. At this time, through the meshing of the second bevel gear 27 and the first bevel gear 25, and the two rotating second bevel gears 27 are respectively located at the adjacent ends of the two first bevel gears 25, so the two first bevel gears 25 will rotate in opposite directions, and the two first bevel gears 25 will drive the two rotating shafts 23 and the emergency lamp bodies 24 to rotate in opposite directions.Thus, the lights of the two emergency light bodies 24 can separately illuminate the positions on both sides.

[0034] An inner mounting plate 22 is fixedly installed at the top of the inner wall of the lighting lamp housing 21. Both of the two rotating shafts 23 are connected to the inner mounting plate 22 through bearings. Fixed plates 46 are fixedly installed on both sides of the lower end of the inner mounting plate 22. Springs 45 are fixedly installed at the separating ends of the two fixed plates 46. The two springs 45 are respectively fixedly connected to the L-shaped rods 44 in two groups of lubricating mechanisms. When it is necessary for the two emergency light bodies 24 on this device to centrally illuminate the position on one side, the user only needs to continue the above operations, make the positioning plate 35 fit with the rightmost annular groove 14 on the rotating rod 11. The gear pin sleeves 12 on the rotating rod 11 and located on both sides will be inserted into the second bevel gears 27 at both side ends and mesh with the two second bevel gears 27. At this time, rotate the rotating rod 11, and the two rotating second bevel gears 27 are respectively located at the left side ends of the two first bevel gears 25. Therefore, the two first bevel gears 25 will rotate in the same direction. The two first bevel gears 25 will drive the two rotating shafts 23 and the emergency light bodies 24 to rotate in the same direction. Thus, the lights of the two emergency light bodies 24 can centrally illuminate the position on one side. In the present invention, the two emergency light bodies 24 and the two rotating shafts 23 are connected together through the first bevel gears 25 and the second bevel gears 27. Thus, the two emergency light bodies 24 can rotate during use, enabling the most efficient utilization of the emergency light bodies 24, such that the emergency light bodies 24 can not only illuminate one position. Thus, more uniform and effective lighting is provided in a specific area. Through rotation, the light source direction can be adjusted according to the actual situation, reducing shadows and dark areas, and ensuring that key areas are fully illuminated. In the present invention, through the rotating rod 11 and the gear pin sleeves 12 provided on the two first bevel gears 25 and the three second bevel gears 27, the emergency light bodies 24 on this device can be adjusted at different angles according to different application scenarios. When light is required on both sides of the device, only need to mesh the two left gear pin sleeves 12 with the two right second bevel gears 27. When it is necessary to centrally illuminate one side, only need to mesh the gear pin sleeves 12 on both sides with the second bevel gears 27 on both sides. Thus, precise angle adjustment of the two emergency light bodies 24 is achieved for this device, improving the utilization rate of the emergency light bodies 24.

[0035] A sliding groove 16 is formed on the circumferential surface of the rotating rod 11. A guide rod is fixedly installed in the sliding groove 16 formed on the rotating rod 11. A moving top block 15 is slidably installed on the guide rod in the sliding groove 16. A elastic piece 34 is fixedly installed at the right end of the lighting lamp housing 21. The wiping plate 32 is attached to the rear end of the safety exit light-transmitting plate 51. Currently, all such devices are provided with a safety exit light-transmitting plate 51. When the safety exit light-transmitting plate 51 has been used for a long time, dust, garbage, etc. will adhere to its inner surface, which is likely to affect the light transmittance of the safety exit light-transmitting plate 51. At this time, only need to move the rotating rod 11 to its original position, the positioning plate 35 will fit with the leftmost annular groove 14 on the rotating rod 11. At this time, the first spur gear 13 on the rotating rod 11 will mesh with the second spur gear 31, and the gear pin sleeve 12 on the rotating rod 11 and the second bevel gear 27 are in a separated state. Rotate the rotating rod 11, the rotating rod 11 will drive the first spur gear 13 to rotate, the first spur gear 13 drives the second spur gear 31 to rotate, and the second spur gear 31 then drives the threaded rod 33 to rotate. Through the threaded connection between the threaded rod 33 and the wiping plate 32, the rotation of the threaded rod 33 will drive the wiping plate 32 to move. And the wiping cloth at the front end of the wiping plate 32 is attached to the inner surface of the safety exit light-transmitting plate 51. Therefore, when the second spur gear 31 moves, the rear end of the safety exit light-transmitting plate 51 can be cleaned. Through the second spur gear 31, the wiping plate 32 and the threaded rod 33 provided inside the lighting lamp housing 21 in the present invention, the inner surface of the safety exit light-transmitting plate 51 can be wiped and cleaned by rotating the rotating rod 11, without the need for cumbersome disassembly and separation of the safety exit light-transmitting plate 51 and the lighting lamp housing 21, thus greatly improving the convenience of cleaning the inner surface of the safety exit light-transmitting plate 51 and avoiding excessive and cumbersome operations by the staff.

[0036] A positioning plate 35 is fixedly installed at the lower end of the elastic piece 34. Three annular grooves 14 are formed on the rotating rod 11. The positioning plate 35 is located in the annular groove 14 formed on the rotating rod 11. The oil pipes 43 in the two lubricating mechanisms are respectively located at the joints of the two rotating shafts 23 and the lighting lamp housing 21. The extrusion block 42 in the lubricating mechanism is attached to the port of the oil pipe 43. The lower end of the L-shaped rod 44 penetrates through and is rotatably installed inside the lighting lamp housing 21. When the wiping plate 32 moves, the wiping plate 32 will contact the L-shaped rods 44 in the two lubricating mechanisms (the L-shaped rods 44 in the two lubricating mechanisms are connected to the lighting lamp housing 21 and the lubricating oil box 41 through rotating oil seals, and there will be no problem of oil leakage), and drive the L-shaped rod 44 to shift in position. When the left L-shaped rod 44 shifts in position, the L-shaped rod 44 will rotate, and the L-shaped rod 44 will drive the extrusion block 42 to rotate. When the extrusion block 42 rotates, it will move away from the port of the oil pipe 43. At this time, the lubricating oil in the lubricating oil box 41 will flow along the oil pipe 43 into the place where the rotating shaft 23 intersects with the lighting lamp housing 21 and the inner mounting plate 22, so as to lubricate the bearing between the inner mounting plate 22 and the rotating shaft 23 and between the first bevel gear 25 and the second bevel gear 27. Through the lubricating mechanisms arranged on both sides of the lighting lamp housing 21, the present invention can lubricate the rotating components of the emergency lamp body 24 in the device, avoiding the reduction of the lighting effect caused by the angle adjustment function of the emergency lamp body 24 being blocked and unable to flexibly point to the area to be illuminated. Moreover, in case of emergencies such as fires or earthquakes, the flexible rotating components can quickly adjust the lighting direction to improve the efficiency of personnel evacuation and rescue work. By rotating the rotating rod 11, the present invention can not only clean the back of the safety exit light-transmitting plate 51, but also seal the gears and bearings in the device, and can perform two operations simultaneously, greatly improving the maintenance efficiency of the internal parts of the device by the staff, and also avoiding the cumbersome disassembly of the device by the staff.

[0037] Working principle:

[0038] First step, when the device is in use, the user can adjust the position of the emergency lamp body 24 on the device according to the usage requirements. When it is necessary for the two emergency lamp bodies 24 on the device to separately illuminate the positions on both sides, by moving the moving top block 15 on the rotating rod 11, move it to the position of the positioning plate 35, and then, through the slope on the moving top block 15, upwardly extrude the positioning plate 35, so as to move the positioning plate 35 out of the annular groove 14 opened on the rotating rod 11. At this time, the rotating rod 11 can be horizontally moved. During the movement, the two gear pin sleeves 12 on the left side of the rotating rod 11 will be inserted into the two second bevel gears 27 on the right side and be in a meshing state with the two second bevel gears 27. And at this time, the positioning plate 35 at the right end of the lighting lamp housing 21 will also fit with the middle annular groove 14 on the rotating rod 11 under the elastic force of the elastic piece 34. At this time, when the rotating rod 11 is rotated, the rotating rod 11 will drive the two gear pin sleeves 12 to rotate, and the two gear pin sleeves 12 will drive the two second bevel gears 27 to rotate. At this time, through the meshing of the second bevel gears 27 and the first bevel gears 25, and the two rotating second bevel gears 27 are respectively located at the adjacent ends of the two first bevel gears 25, so the two first bevel gears 25 will rotate in opposite directions, and the two first bevel gears 25 will drive the two rotating shafts 23 and the emergency lamp bodies 24 to rotate in opposite directions, so that the lights of the two emergency lamp bodies 24 can separately illuminate the positions on both sides.

[0039] Step 2, when it is necessary for the two emergency lamp bodies 24 on the device to concentrate illumination on a position on one side, the user only needs to continue the above operations, making the positioning plate 35 fit with the rightmost annular groove 14 on the rotating rod 11. The gear pin sleeves 12 on both sides of the rotating rod 11 will be inserted into the second bevel gears 27 at both ends and mesh with the two second bevel gears 27. At this time, rotate the rotating rod 11, and the two rotating second bevel gears 27 are respectively located at the left ends of the two first bevel gears 25. Therefore, the two first bevel gears 25 will rotate in the same direction, and the two first bevel gears 25 will drive the two rotating shafts 23 and the emergency lamp bodies 24 to rotate in the same direction, so that the light of the two emergency lamp bodies 24 can concentrate illumination on a position on one side. In the present invention, by connecting the two emergency lamp bodies 24 and the two rotating shafts 23 together through the first bevel gears 25 and the second bevel gears 27, the two emergency lamp bodies 24 can rotate during use, enabling the most efficient utilization of the emergency lamp bodies 24, so that the emergency lamp bodies 24 can not only illuminate one position, thereby providing more uniform and effective illumination in a specific area. Through rotation, the light source direction can be adjusted according to the actual situation, reducing shadows and dark areas, and ensuring that key areas are fully illuminated. In the present invention, through the rotating rod 11 and the gear pin sleeves 12 provided on the two first bevel gears 25 and the three second bevel gears 27, the emergency lamp bodies 24 on the device can be adjusted at different angles according to different application scenarios. When light is required on both sides of the device, only need to mesh the two left gear pin sleeves 12 with the two right second bevel gears 27, and when it is necessary to concentrate illumination on one side, only need to mesh the gear pin sleeves 12 on both sides with the second bevel gears 27 on both sides, so as to achieve precise angle adjustment of the two emergency lamp bodies 24 on the device and improve the utilization rate of the emergency lamp bodies 24.

[0040] Step 3: Currently, a safety exit light-transmitting plate 51 is provided on the device. When the safety exit light-transmitting plate 51 has been used for a long time, dust, garbage, etc. will adhere to its inner surface, which is likely to affect the light transmittance of the safety exit light-transmitting plate 51. At this time, just move the rotating rod 11 to its original position, and the positioning plate 35 will fit with the leftmost annular groove 14 on the rotating rod 11. At this time, the first spur gear 13 on the rotating rod 11 will mesh with the second spur gear 31, and the gear pin sleeve 12 on the rotating rod 11 and the second bevel gear 27 are in a separated state. Rotate the rotating rod 11, and the rotating rod 11 will drive the first spur gear 13 to rotate. The first spur gear 13 drives the second spur gear 31 to rotate, and the second spur gear 31 then drives the threaded rod 33 to rotate. Through the threaded connection between the threaded rod 33 and the wiping plate 32, the rotation of the threaded rod 33 will drive the wiping plate 32 to move. The wiping cloth at the front end of the wiping plate 32 is in contact with the inner surface of the safety exit light-transmitting plate 51. Therefore, when the second spur gear 31 moves, the rear end of the safety exit light-transmitting plate 51 can be cleaned. Through the second spur gear 31, wiping plate 32 and threaded rod 33 provided inside the lighting lamp housing 21, the present invention can wipe and clean the inner surface of the safety exit light-transmitting plate 51 by rotating the rotating rod 11, without the need for cumbersome disassembly and separation of the safety exit light-transmitting plate 51 and the lighting lamp housing 21, thus greatly improving the convenience of cleaning the inner surface of the safety exit light-transmitting plate 51 and avoiding excessive and cumbersome operations by the staff.

[0041] Step 4: When the wiping plate 32 is moving, the wiping plate 32 will contact the L-shaped rods 44 in the two lubricating mechanisms (the L-shaped rods 44 in the two lubricating mechanisms are connected to the lighting lamp housing 21 and the lubricating oil box 41 through rotating oil seals, and there will be no oil leakage problem), and drive the L-shaped rods 44 to shift in position. When the left L-shaped rod 44 shifts in position, the L-shaped rod 44 will rotate, and the L-shaped rod 44 will drive the extrusion block 42 to rotate. When the extrusion block 42 rotates, it will move away from the port of the oil pipe 43. At this time, the lubricating oil in the lubricating oil box 41 will flow into the place where the rotating shaft 23 intersects with the lighting lamp housing 21 and the inner mounting plate 22 along the oil pipe 43, so as to lubricate the bearings between the inner mounting plate 22 and the rotating shaft 23 and between the first bevel gear 25 and the second bevel gear 27. Through the lubricating mechanisms provided on both sides of the lighting lamp housing 21, the present invention can lubricate the rotating components of the emergency lamp body 24 in the device, avoiding the reduction of the lighting effect caused by the angle adjustment function of the emergency lamp body 24 being blocked and unable to flexibly point to the area to be illuminated. Moreover, in case of emergencies such as fires or earthquakes, the flexible rotating components can quickly adjust the lighting direction and improve the efficiency of personnel evacuation and rescue work.

[0042] By rotating the rotating rod 11, the present invention can not only clean the back of the safety exit light-transmitting plate 51, but also seal the gears and bearings inside the device. It can perform two operations simultaneously, greatly improving the maintenance efficiency of the internal parts of the device by the staff, and also avoiding the cumbersome disassembly of the device by the staff.

[0043] Finally, it should be noted that: Obviously, the above embodiments are merely examples given to clearly illustrate the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
