[0031] During work, a warning device is installed on the guardrail to achieve a warning effect, but the height of the guardrail is limited. When warning at night, if a driver is sitting in the car, he cannot observe the warning device in front of the construction site, resulting in a blind spot, which causes the vehicle to enter the construction site. In order to prevent such incidents from happening, first, a warning sign 6 is placed in the warning base 5. The warning sign 6 is made of reflective material. When illuminated at night, it can play a warning role. After the warning sign 6 is placed, the lifting screw 46 in the lifting box 8 is driven to rotate. The lifting screw 46 is set in two groups. When rotating, the lifting screw 46 drives the two groups of lifting blocks 461 to rise. The side wall of the lifting block 461 is fixedly connected to the connecting plate 9. The connecting plate 9 is rotatably provided with a connecting shaft 91. The connecting shaft 91 is fixedly connected to the warning base 5. When the lifting block 461 is driven to rise, the warning base 5 is driven to rise through the connecting plate 9, thereby increasing the height of the warning sign 6. Through the setting of the connecting shaft 91, the warning base 5 can be rotated according to the style of the warning sign 6 in the warning base 5, so as to conveniently remind passers-by.

[0032] like Figure 3 and Figure 4As shown, a transmission support block 44 is fixedly connected to the support base 1; two groups of transmission support blocks 44 are provided; a transmission rod 43 is rotatably connected to the side wall of the transmission support block 44; transmission gears 42 are fixedly connected to both ends of the transmission rod 43; a lifting gear 45 is fixedly connected to the bottom of the lifting screw 46; the lifting gear 45 is meshingly connected with the transmission gear 42; a driving support block 412 is fixedly connected to the support base 1; a hand crank 411 is rotatably connected to the side wall of the driving support block 412; a driving gear 41 is fixedly connected to the end of the hand crank 411; the driving gear 41 is meshingly connected with the transmission gear 42 away from the lifting gear 45;

[0033] During operation, when driving the lifting screw 46 to rotate, first rotate the hand crank 411. When the hand crank 411 rotates, it will drive the driving gear 41 to rotate, thereby driving the two sets of transmission gears 42 to rotate. When the two sets of transmission gears 42 rotate, the lifting gear 45 will be driven to rotate through the transmission gear 42 in the lifting box 8, thereby driving the lifting screw 46 to rotate, thereby lifting the warning base 5 and the warning sign 6.

[0034] like Figure 5 and Figure 6 As shown, the side wall of the warning base 5 is provided with a clamping assembly 7; the clamping assembly 7 includes a clamping box 71; the top of the clamping box 71 is fixedly connected to a top plate 72; a slide plate 73 is fixedly connected inside the clamping box 71; a clamping spring 76 is fixedly connected to the side wall of the slide plate 73 away from the top plate 72; a clamping block 77 is fixedly connected to the end of the clamping spring 76; a return spring 74 is fixedly connected to the side wall of the slide plate 73 away from the clamping spring 76; one end of the return spring 74 away from the slide plate 73 is fixedly connected to the top plate 72; a pull rod 75 is fixedly connected to the side wall of the slide plate 73; the pull rod 75 is arranged to penetrate the top plate 72; a clamping groove 61 is opened on the side wall of the warning sign 6; the inner diameter of the clamping groove 61 is consistent with the size of the clamping block 77;

[0035] During operation, the warning sign 6 in the warning base 5 is clamped through the clamping assembly 7, and the clamping assembly 7 includes a clamping box 71. First, the warning sign 6 is slid and inserted into the warning base 5. During insertion, the bottom of the warning sign 6 abuts against the clamping block 77, thereby squeezing the clamping block 77 into the clamping box 71. When the warning sign 6 is fully inserted into the warning base 5, the clamping block 77 and the clamping slot 61 are in a parallel position. At this time, the clamping spring 76 rebounds and bounces the clamping block 77 into the clamping slot 61 to achieve the clamping of the warning sign 6. When the warning sign 6 needs to be removed, the staff can pull the pull rod 75. When pulling, the pull rod 75 drives the slide plate 73 to move toward the top plate 72, thereby bringing the clamping block 77 into the clamping box 71. At this time, the warning sign 6 is unstuck and the warning sign 6 can be taken out.

[0036] like Figure 5As shown, a bottom groove 52 is formed at the bottom of the warning base 5; a telescopic spring 53 is fixedly connected in the bottom groove 52; a plurality of groups of telescopic springs 53 are provided; and a bottom plate 54 is fixedly connected to the end of the telescopic spring 53;

[0037] During operation, when the warning sign 6 is fully inserted into the warning base 5, the bottom of the warning sign 6 abuts against the bottom plate 54 and squeezes the bottom plate 54 into the bottom groove 52. When the clamping block 77 is disengaged from the clamping groove 61, the bottom plate 54 is no longer squeezed. At this time, the telescopic spring 53 rebounds and pops the warning sign 6 out of the warning base 5.

[0038] like Figure 1 As shown, the lifting box 8 is fixedly connected to the support base 1; the end of the lifting box 8 away from the support base 1 is fixedly connected to the support frame 2;

[0039] During operation, two ends of the lifting box 8 are fixedly connected to the supporting base 1 and the supporting frame 2 respectively.

[0040] like Figure 2 As shown, the bottom of the support base 1 is fixedly connected to a telescopic leg 3; the bottom of the telescopic leg 3 is fixedly connected to a rubber pad 31;

[0041] During operation, the telescopic legs 3 can support the warning device, and the rubber pads 31 can prevent the telescopic legs 3 from slipping.

[0042] like Figure 2 As shown, the bottom of the support base 1 is rotatably connected to a moving wheel 11; the moving wheel 11 is provided with two groups;

[0043] During operation, when movement is required, the telescopic legs 3 are retracted, and after retraction, the moving wheels 11 are in contact with the ground, so that the moving wheels 11 drive the warning device to move. After the movement is completed, the telescopic legs 3 are unfolded, and the rubber pads 31 are in contact with the ground, thereby supporting the warning device.

[0044] The working principle of the utility model is as follows: a warning device is installed on the guardrail to achieve a warning effect, but the height of the guardrail is limited. When warning at night, if a driver is sitting in the car, he cannot observe the warning device in front of the construction site, resulting in a blind spot, which causes the vehicle to enter the construction site. In order to prevent such incidents from happening, first, a warning sign 6 is placed in the warning base 5. The warning sign 6 is made of reflective material. When it is illuminated at night, it can play a warning role. After the warning sign 6 is placed, the lifting screw 46 in the lifting box 8 is driven to rotate. The lifting screw 46 is set in two groups. When rotating, the lifting screw 46 drives the two groups of lifting blocks 461 to rise. The side wall of the lifting block 461 is fixedly connected to the connecting plate 9. The connecting plate 9 is rotatably provided with a connecting shaft 91. The connecting shaft 91 is fixedly connected to the warning base 5. When the lifting block 461 is driven to rise, the warning base 5 is driven to rise through the connecting plate 9, thereby increasing the height of the warning sign 6. Through the setting of the connecting shaft 91, the warning base 5 can be rotated according to the style of the warning sign 6 in the warning base 5, so as to remind passers-by conveniently.

[0045] Among them, the warning sign 6 is fixed by the snap-fitting assembly 7, and the warning sign 6 in the warning base 5 is snap-fitted by the snap-fitting assembly 7. The snap-fitting assembly 7 includes a snap-fitting box 71. First, the warning sign 6 is slidably inserted into the warning base 5. During insertion, the bottom of the warning sign 6 abuts against the snap-fitting block 77, thereby squeezing the snap-fitting block 77 into the snap-fitting box 71. When the warning sign 6 is fully inserted into the warning base 5, the snap-fitting block 77 is in a parallel position with the snap-fitting groove 61. At this time, the snap-fitting spring 76 rebounds and bounces the snap-fitting block 77 into the snap-fitting groove 61 to achieve the snap-fitting of the warning sign 6. When the warning sign 6 needs to be removed, the staff can pull the pull rod 75. When pulling, the pull rod 75 drives the slide plate 73 to move toward the top plate 72, thereby bringing the snap-fitting block 77 into the snap-fitting box 71. At this time, the warning sign 6 is unstuck and the warning sign 6 can be taken out.

[0046] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
