[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0016] Example like Figures 1-4 As shown, this embodiment proposes a lifting lighting lamp for fire trucks, including a mounting plate 1. A first support rod 2 is fixedly installed on the top of the mounting plate 1. A second support rod 3 is slidably installed inside the first support rod 2. A slider 4 is fixedly installed at the bottom of the second support rod 3. Two limiting rods 5 are fixedly installed on the outside of the slider 4, and the limiting rods 5 slide through the outer wall of the first support rod 2. A limiting structure for limiting the slider 4 is provided at the bottom of the inside of the second support rod 3. A C-shaped plate 14 is slidably installed on the outside of the first support rod 2. The limiting rods 5 pass through the C-shaped plate 14. Side plates 15 are fixedly installed at both ends of the C-shaped plate 14. A fixing bolt 16 slides through the two side plates 15. A connector 17 is fixedly installed at the top of the second support rod 3. A rotating part is provided inside the connector 17. Mounting rod 18 has two lighting lamps 19 fixedly installed on its outer side. Connector 17 has a fastening structure on its outer side for limiting the position of mounting rod 18. In use, the first support rod 2 is mounted on the fire truck via mounting plate 1. A second support rod 3 is slidably installed inside the first support rod 2. The top of the second support rod 3 is connected to the mounting rod 18 via connector 17. The illumination angle of the lighting lamps 19 on the outer side of the mounting rod 18 is adjusted by rotating the mounting rod 18. When height adjustment is required, the second support rod 3 is slid. After adjusting to the appropriate position, the slider 4 is initially limited by the limiting structure, and then tightened by fixing bolts 16 to fix the second support rod 3. The height of the lighting lamps 19 is adjusted via the second support rod 3.
[0017] The limiting structure includes a fixing rod 6, which is fixedly installed inside the slider 4. A spring 7 is sleeved on the outside of the fixing rod 6. Two sliding plates 8 are slidably arranged on the outside of the fixing rod 6. A fixing block 9 is fixedly installed at the bottom end of the sliding plate 8. An arc-shaped plate 10 is fixedly installed on one side of the fixing block 9 and is slidably installed at the bottom of the slider 4. Multiple plug-in rods 11 are fixedly installed on one side of the arc-shaped plate 10. The limiting rod 5 has a pressing structure inside for pushing the arc-shaped plate 10. The lighting is controlled by sliding through the second support rod 3. When the height of lamp 19 is adjusted, the sliding plate 8 is pushed to slide by the extrusion structure. The sliding plate 8 will cause the arc plate 10 to slide. The plug rod 11 on one side of the arc plate 10 separates from the first support rod 2, and then slides the second support rod 3. After the sliding is completed, the deformed spring 7 will apply an outward force to the sliding plate 8, thereby pushing the arc plate 10 to slide outward. The plug rod 11 on the outside of the arc plate 10 is inserted into the inner wall of the first support rod 2, thereby initially limiting the second support rod 3 and facilitating the fixation of the second support rod 3.
[0018] The outer wall of the first support rod 2 is evenly provided with multiple grooves. The size of the plug rod 11 is adapted to the grooves. The slider 4 is limited by plugging the plug rod 11 into the grooves.
[0019] The bottom of slider 4 has a groove, and the sliding plate 8 is slidably installed inside the groove. The arc plate 10 is slidably installed at the bottom of slider 4 via the sliding plate 8.
[0020] The extrusion structure includes a pressing block 12, which is slidably installed inside the limiting rod 5. A push rod 13 is fixedly provided on one side of the pressing block 12. The push rod 13 slides through the limiting rod 5 and extends into the slider 4. When the second support rod 3 is slid, the pressing block 12 is pressed, which causes the push rod 13 on one side of the pressing block 12 to push the sliding plate 8 to move, thereby causing the arc plate 10 to slide.
[0021] The fastening structure includes a threaded sleeve 20, which is fixedly installed on the outside of the connector 17. The internal thread of the threaded sleeve 20 passes through a limit bolt 21, and the limit bolt 21 is fastened to the outer wall of the mounting rod 18. After the illumination angle of the lighting lamp 19 is adjusted by rotating the mounting rod 18, the limit bolt 21 is rotated so that one end of the limit bolt 21 is inserted into the outer wall of the mounting rod 18, thereby limiting the mounting rod 18.
[0022] Multiple limiting grooves are evenly provided on the outer wall of the mounting rod 18. One end of the limiting bolt 21 is inserted into one of the limiting grooves. The mounting rod 18 is limited by the limiting bolt 21, thereby adjusting the illumination angle of the lighting lamp 19 on the outside of the mounting rod 18.
[0023] In this embodiment, during use, the first support rod 2 is installed on the fire truck via the mounting plate 1. A second support rod 3 is slidably disposed inside the first support rod 2. The top of the second support rod 3 is connected to a mounting rod 18 via a connector 17. The illumination angle of the lighting lamp 19 on the outside of the mounting rod 18 is adjusted by rotating the mounting rod 18. After adjustment, the limiting bolt 21 is rotated so that one end of the limiting bolt 21 is inserted into the outer wall of the mounting rod 18, thereby limiting the mounting rod 18. When height adjustment is required, the pressing block 12 is pressed, causing the push rod 13 on one side of the pressing block 12 to push the sliding plate 8 to move, thus causing the arc-shaped plate 10 to slide... When the arc-shaped plate 10 moves, the insertion rod 11 on one side separates from the inner wall of the first support rod 2. At the same time, the spring 7 on the outside of the fixing rod 6 deforms. Then, the second support rod 3 slides and is adjusted to a suitable position. The deformed spring 7 will apply an outward force to the sliding plate 8, thereby pushing the arc-shaped plate 10 to slide outward. The insertion rod 11 on the outside of the arc-shaped plate 10 inserts into the inner wall of the first support rod 2, thereby initially limiting the second support rod 3 and facilitating its fixation. Then, the C-shaped plate 14 is tightened by the fixing bolt 16, thereby fixing the second support rod 3. The height of the lighting lamp 19 is adjusted by the second support rod 3.
[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
