[0025] See also Figure 1-4 The utility model provides a new technical solution: an LED subway safety warning light, comprising an L-shaped mounting plate 1, four bolt holes 2 are opened on the vertical plate of the L-shaped mounting plate 1, and two columns 3 are fixedly installed on the opposite surface of the horizontal plate of the L-shaped mounting plate 1;

[0026] A fixing mechanism, the fixing mechanism is arranged on the outer surface of the two columns 3, the fixing mechanism is used to fix the warning lamp for warning, and the fixing mechanism includes a moving plate 4, and the moving plate 4 is slidably sleeved on the outer surface of the two columns 3;

[0027] The adjusting mechanism is arranged on the movable plate 4 . The adjusting mechanism is used to adjust the height of the warning lamp. The adjusting mechanism comprises a screw motor 6 . The screw motor 6 is fixedly mounted on the upper surface of the L-shaped mounting plate 1 .

[0028] Furthermore, four slide grooves 8 are provided on the upper surface of the movable plate 4 , and an LED warning light 7 is provided on the upper surface of the movable plate 4 .

[0029] Furthermore, the fixing mechanism also includes a threaded rod 9, a knob 10 and a collar 11. The threaded rod 9 is rotatably connected to the lower surface of the movable plate 4, the knob 10 is fixedly installed at the lower end of the threaded rod 9, and the collar 11 is threadedly sleeved on the outer surface of the threaded rod 9.

[0030] Furthermore, the fixing mechanism also includes four support rods 12 and four sliding blocks 13. The four support rods 12 are rotatably connected to the outer surface of the ring 11, the four sliding blocks 13 are rotatably connected to one end of the four support rods 12 away from the ring 11, and the four sliding blocks 13 are slidably connected to the four slide grooves 8 respectively.

[0031] Furthermore, the fixing mechanism further includes four annular clamping plates 14 , which are fixedly mounted on the upper surfaces of the four sliding blocks 13 .

[0032] Furthermore, the adjustment mechanism also includes a screw rod 5, the lower end of which is rotatably connected to the opposite side of the horizontal plate of the L-shaped mounting plate 1, and the upper end of the screw rod 5 passes through the upper surface of the horizontal plate of the L-shaped mounting plate 1, and the upper end of the screw rod 5 is fixedly connected to the output end of the screw motor 6.

[0033] When the LED subway safety protection warning light is used, the LED warning light 7 is placed between the four circular clamping plates 14, and then the knob 10 is turned, so that the knob 10 drives the threaded rod 9 fixedly installed on the upper surface to rotate, and then the collar 11 on the outer surface of the threaded rod 9 is continuously moved downward through the thread set on the outer surface of the threaded rod 9, and at the same time, the collar 11 drives the four support rods 12 connected to the outer surface to move downward, and the four support rods 12 are gradually arranged vertically while moving, and at the same time, the four support rods 12 apply relative surface tension to the sliding block 13 connected to the end of the sleeve 11, so that the four sliding blocks 13 move toward the relative surface in the slide groove 8, and at the same time, the four sliding blocks 13 drive the four circular rings fixedly installed on the upper surface. The clamping plate 14 moves toward the opposite surface, and at this time, the four annular clamping plates 14 are attached to the outer surface of the LED warning light 7 for clamping and fixing. When the LED warning light 7 needs to be disassembled, the knob 10 can be rotated in the opposite direction to drive the four annular clamping plates 14 to separate from the outer surface of the LED warning light 7 to complete the disassembly. At this time, by starting the screw motor 6, the screw motor 6 outputs power to the screw 5 fixedly installed at the output end through operation, so that it rotates. At this time, the movable plate 4 with a thread sleeve on the outer surface of the screw 5 continues to move upward through the thread set on the outer surface of the screw 5. The movable plate 4 is restricted by the two columns 3 so that it can only move up and down stably. At this time, the LED warning light 7 set on the movable plate 4 can be driven to move upward to complete the adjustment;

[0034] The LED subway safety protection warning light can be clamped and fixed by a self-centering clamping mechanism. Compared with the traditional method of fixing the LED warning light in the subway through a threaded structure, the device can facilitate the disassembly of the LED warning light, which is convenient for daily maintenance and battery replacement of the LED warning light, ensuring the stable operation of the LED warning light, and further improving the safety warning capability in the subway. In addition, the LED subway safety protection warning light can be driven by a screw motor to move up and down, which is convenient for staff of different heights to inspect and repair the LED safety protection warning light, thereby improving the inspection efficiency.

[0035] Working principle: When the LED subway safety protection warning light is used, the LED warning light 7 is placed between four circular clamping plates 14. At this time, by turning the knob 10, the knob 10 drives the threaded rod 9 fixedly installed on the upper surface to rotate. At this time, the ring 11 on the outer surface of the threaded rod 9 is continuously moved downward through the thread set on the outer surface of the threaded rod 9. At the same time, the ring 11 drives the four support rods 12 connected to the outer surface to move downward. The four support rods 12 are gradually set vertically while moving. At the same time, the four support rods 12 apply relative surface tension to the sliding block 13 connected to the end of the sliding block 11, so that the four sliding blocks 13 move toward the relative surface in the slide groove 8. At the same time, the four sliding blocks 13 drive the four fixedly installed on the upper surface. The four annular clamps 14 move toward the opposite surface, and at this time, the four annular clamps 14 fit the outer surface of the LED warning light 7 for clamping and fixing. When the LED warning light 7 needs to be disassembled, the knob 10 can be rotated in the opposite direction to drive the four annular clamps 14 to separate from the outer surface of the LED warning light 7 to complete the disassembly. At this time, by starting the screw motor 6, the screw motor 6 outputs power to the screw 5 fixedly installed at the output end through operation, so that it rotates. At this time, the movable plate 4 with a thread sleeve on the outer surface of the screw rod 5 continues to move upward through the thread set on the outer surface of the screw rod 5. Due to the restriction of the two columns 3, the movable plate 4 can only be stably displaced up and down, and the LED warning light 7 set on the movable plate 4 can be driven to move upward to complete the adjustment.
