[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 , 2 As shown in Figure 4, an adjustable warning sign for construction according to an embodiment of the utility model comprises a warning sign body 1; a base 11 is provided on the side wall of the warning sign body 1; a slide 12 is fixedly connected to the side wall of the base 11; a slide bar 13 is slidably connected to the inner side wall of the slide 12; the slide bar 13 is fixedly connected to the warning sign body 1; a servo motor 14 is fixedly connected to the side wall of the base 11; a first screw 15 is fixedly connected to the output end of the servo motor 14; the side wall of the first screw 15 is rotatably connected to The slider 16 is fixedly connected to the warning sign body 1; a first telescopic rod 17 is fixedly connected between the slider 16 and the slide 12; a pair of fixing frames 18 are fixedly connected to the side wall of the slide 12; the fixing frames 18 are symmetrically arranged on both sides of the slide 12 and have the same structure; a plurality of cleaning brushes 19 are evenly fixedly connected to the side wall of the fixing frame 18; when in use, by starting the servo motor 14, the first screw 15 is driven to rotate under the action of the servo motor 14, and as the first screw 15 rotates, the slider 16 can be driven to rotate. The block 16 performs a lifting movement, and the first telescopic rod 17 performs a telescopic movement to maintain the stable movement of the warning sign body 1. At the same time, under the sliding cooperation between the slide cylinder 12 and the slide rod 13, the slide rod 13 will slide on the inner wall of the slide cylinder 12, so that the height of the warning sign body 1 can be adjusted, and in the process of sliding the slide rod 13, the side wall of the slide rod 13 will contact the cleaning brush 19, and the dust and impurities attached to the side wall of the slide rod 13 can be swept away by the cleaning brush 19, so that they will not be blocked between the slide cylinder 12 and the slide rod 13. In this process, the existing warning sign body 1 can be reduced. It is not convenient to adjust the height when in use, which makes it easy to be blocked by other objects, thereby affecting the warning effect of the warning sign body 1 to a certain extent. At this time, the first screw 15 is set, and then the height of the warning sign body 1 is adjusted when in use. At the same time, the cleaning brush 19 can clean the dust and impurities attached to the side wall of the slide rod 13, thereby improving the sliding effect between the slide cylinder 12 and the slide rod 13.

[0025] like Figure 1 , 2As shown in Figures 5 and 6, a plurality of universal wheels 2 are evenly fixed to the bottom of the base 11; a pair of brackets 21 are fixed to the side walls of the base 11; the brackets 21 are symmetrically arranged on both sides of the base 11 and have the same structure; a second screw 22 is rotatably connected to the side wall of the bracket 21; the second screw 22 penetrates the wall of the bracket 21 and is rotatably connected thereto; an extrusion plate 23 is rotatably connected to the end of the second screw 22; a plurality of fixing rods 24 are evenly fixed to the side walls of the extrusion plate 23; when in use, the universal wheels 2 can be made to roll on the ground by pushing the warning sign body 1, so that the warning sign body 1 can be moved conveniently. When the movement is completed, the first screw 22 is held by the user. The two screws 22 rotate simultaneously, and the extrusion plate 23 can be pushed down and brought closer to the ground by rotating the second screw 22. Then, by continuously rotating the second screw 22, the extrusion plate 23 can apply a certain pressure to the ground, and the fixing rod 24 will be pressed against the ground. When there is soil around, the fixing rod 24 will be inserted into the soil, and then the universal wheel 2 can be fixed. In this process, the weight of the warning sign body 1 can be reduced to a certain extent, which makes it inconvenient to move it, and the moving process is more cumbersome, thereby increasing a certain amount of workload. At this time, the universal wheel 2 is set to facilitate the movement of the warning sign body 1.

[0026] like Figure 5 As shown, a pair of through holes 3 are symmetrically opened on the side wall of the extrusion plate 23; a pair of second telescopic rods 31 are fixedly connected to the side wall of the extrusion plate 23; the second telescopic rods 31 are symmetrically arranged on both sides of the extrusion plate 23 and have the same structure; a spring 32 is sleeved on the outer side of the second telescopic rod 31; the spring 32 and the through hole 3 are in sliding fit; the ends of the second telescopic rod 31 and the spring 32 are fixedly connected to the same rubber block 33; when in use, when the extrusion plate 23 is rotated and moved to a specified degree, the rubber block 33 will first contact the ground, and then through the continuous descent of the extrusion plate 23, the rubber block 33 will generate a certain pressure on the second telescopic rod 31 and the spring 32, and by squeezing the second telescopic rod 31 and the spring 32, The rubber block 33 is then pressed against the ground, and the second telescopic rod 31 is then telescopically moved to maintain the rubber block 33 to move smoothly. Thereafter, a certain friction force is generated by the contact between the rubber block 33 and the ground, thereby fixing the base 11. In this process, the poor fixing effect of the warning sign body 1 can be reduced, which may cause the universal wheel 2 to move easily when the warning sign body 1 is accidentally hit, thereby affecting the stability of the warning sign body 1 to a certain extent. At this time, the rubber block 33 is provided to further increase the fixing effect of the warning sign body 1 when in use.

[0027] like Figure 2 , 3As shown, a pair of slide rails 4 are fixedly connected to the side walls of the warning sign body 1; the slide rails 4 are symmetrically arranged on both sides of the warning sign body 1 and have the same structure; an insert block 41 is slidably connected to the inner wall of the slide rail 4; a rubber pad 42 is fixedly connected to the side wall of the insert block 41; a reflective panel 43 is fixedly connected to the side wall of the insert block 41; when in use, the staff holds the reflective panel 43 and inserts the insert block 41 into the inner wall of the slide rail 4. At this time, a certain friction force will be generated due to the full contact between the rubber pad 42 and the slide rail 4, so that the reflective panel 43 can be fixed. Then, when the staff When passing behind the warning sign body 1, the reflective panel 43 can reflect light to warn the staff and reduce the risk of the staff bumping into the wall of the warning sign body 1. In this process, the back of the warning sign body 1 can be reduced to have no reflective effect, which makes it easy for the staff to bump into the wall of the warning sign body 1 when passing behind the warning sign body 1. At this time, the reflective panel 43 is set up to play a warning role when the warning sign body 1 is in use. At the same time, with the cooperation of the slide rail 4 and the plug 41, the reflective panel 43 can be replaced conveniently.

[0028] like Figure 4 As shown, a connecting rope 5 is fixedly connected to the side wall of the fixing frame 18; a counterweight ball 51 is fixedly connected to the end of the connecting rope 5; when in use, when the external wind blows the counterweight ball 51, it can cause it to swing, thereby causing the connecting rope 5 to shake, and at the same time, under the action of the gravity of the counterweight ball 51, the swing amplitude of the connecting rope 5 can be increased, and then the counterweight ball 51 will hit the wall of the fixing frame 18 during the swinging process, and the dust and impurities attached to the side wall of the cleaning brush 19 can be vibrated off by the vibration generated by the collision. In this process, the cleaning brush 19 can be reduced after a long period of use, resulting in more dust and impurities attached to the side wall of the cleaning brush 19, thereby causing a certain impact on the cleaning effect of the cleaning brush 19. At this time, the connecting rope 5 and the counterweight ball 51 are set, thereby playing a role in cleaning the dust and impurities attached to the side wall of the cleaning brush 19.

[0029] like Figure 2 , 4 As shown, the side wall of the fixing frame 18 is fixedly connected with the guide plate 6; when in use, when the slide bar 13 is sliding, the side wall of the slide bar 13 will contact the guide plate 6, and the dust and impurities attached to the side wall of the slide bar 13 can be scraped off by the guide plate 6. At the same time, the dust and impurities swept away by the cleaning brush 19 will also fall on the side wall of the guide plate 6 and then slide to the outside. In this process, the cleaning effect of the cleaning brush 19 can be reduced, resulting in some dust and impurities still remaining on the side wall of the slide bar 13, thereby causing a certain impact on the sliding effect of the slide bar 13 and the slide cylinder 12. At this time, the guide plate 6 is set to further increase the cleaning effect of the dust and impurities attached to the side wall of the slide bar 13, and it can also play a role in guiding the dust and impurities.

[0030] like Figure 4 As shown, the side wall of the cleaning brush 19 is fixedly connected with a connecting rod 7; the connecting rod 7 passes through the wall of the cleaning brush 19 and is fixedly connected thereto; when in use, multiple cleaning brushes 19 can be fixedly connected by the connecting rod 7 so that they are concentrated together during the cleaning process. In this process, the cleaning brush 19 can be reduced to be relatively scattered during cleaning, resulting in poor cleaning effect of the cleaning brush 19, causing some dust and impurities to still adhere to the side wall of the slide bar 13. At this time, the connecting rod 7 is set to increase the concentration of the cleaning brush 19 during cleaning, thereby improving the cleaning effect.

[0031] When working, by starting the servo motor 14, the first screw rod 15 will be driven to rotate under the action of the servo motor 14. As the first screw rod 15 rotates, the slider 16 can be lifted and lowered, and the first telescopic rod 17 can be telescopic to maintain the stable movement of the warning sign body 1. At the same time, under the sliding cooperation between the slide cylinder 12 and the slide rod 13, the slide rod 13 will slide on the inner wall of the slide cylinder 12, so that the height of the warning sign body 1 can be adjusted. In the process of sliding the slide rod 13, the side wall of the slide rod 13 will contact the cleaning brush 19. The cleaning brush 19 can sweep away dust and impurities attached to the side wall of the slide rod 13 so that they will not be blocked between the slide cylinder 12 and the slide rod 13. When in use, by pushing the warning sign body 1, the universal wheel 2 The second screw rod 22 is rotated on the ground, so that the warning sign body 1 can be easily moved. When the movement is completed, the second screw rod 22 is held and rotated. By rotating the second screw rod 22, the extrusion plate 23 can be pushed down to make it close to the ground. Then, by continuously rotating the second screw rod 22, the extrusion plate 23 can apply a certain pressure to the ground, and the fixing rod 24 will be against the ground. When there is mud around, the fixing rod 24 will be inserted into the mud, and then the universal wheel 2 can be fixed. When in use, when the extrusion plate 23 is rotated and moved to a specified degree, the rubber block 33 will first contact the ground, and then through the continuous descent of the extrusion plate 23, the rubber block 33 will generate a certain pressure on the second telescopic rod 31 and the spring 32, and by squeezing the second telescopic rod 31 and the spring 3 2 can make it telescopic movement, and at the same time, the elastic action of the spring 32 will exert a certain reaction force on the rubber block 33, pressing the rubber block 33 to the ground, and the second telescopic rod 31 will telescopic movement to maintain the rubber block 33 to move smoothly, and then a certain friction force will be generated by the contact between the rubber block 33 and the ground, so that the base 11 can be fixed. When in use, the staff holds the reflective panel 43 and inserts the insert block 41 into the inner wall of the slide rail 4. At this time, a certain friction force will be generated by the full contact between the rubber pad 42 and the slide rail 4, so that the reflective panel 43 can be fixed. Later, when the staff passes behind the warning sign body 1, the reflective panel 43 can reflect light to warn the staff. The present invention shows that the staff can reduce the risk of hitting the wall of the warning sign body 1. When in use, when the external wind blows the counterweight ball 51, it can swing, thereby causing the connecting rope 5 to shake. At the same time, under the action of the gravity of the counterweight ball 51, the swing amplitude of the connecting rope 5 can be increased. Then, during the swinging process of the counterweight ball 51, it will hit the wall of the fixing frame 18. The vibration generated by the impact can vibrate off the dust and impurities attached to the side wall of the cleaning brush 19. When in use, when the slide bar 13 is sliding, the side wall of the slide bar 13 will contact the guide plate 6. The dust and impurities attached to the side wall of the slide bar 13 can be scraped off by the guide plate 6. At the same time, the dust and impurities cleaned by the cleaning brush 19 will also fall on the side wall of the guide plate 6 and then slide to the outside. When in use,The connecting rod 7 can be used to connect multiple cleaning brushes 19 so that they can be brought together during the cleaning process.
