[0024] The following will describe in detail the implementation manners of the present application in conjunction with the accompanying drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.

[0025] Embodiment 1

[0026] After the existing chemical safety warning signs are installed on site, they are not convenient to disassemble. In order to reduce the possibility of the warning signs falling, the warning signs need to have a certain mass, resulting in a large weight that needs to be overcome when handling the warning signs, making it difficult to adjust the position of the warning signs during handling, and it is difficult for a single person to complete the work of handling the warning signs. In order to reduce the handling difficulty of the warning signs and make them convenient for a single person to handle, referring to Figures 1-4 As an embodiment of the present utility model, a chemical safety warning sign is proposed, including a base 1. A plurality of universal wheels are installed at the bottom of the base 1. A sleeve 2 is fixedly connected to the top of the base 1. A warning sign 3 with one end movably extending into its interior is provided at the top of the sleeve 2. Among them: the warning sign 3 includes a warning board 31 located above the sleeve 2. A round rod 32 is fixedly connected to the bottom of the warning board 31. A cross bar 33 is fixedly connected to the bottom of the round rod 32; a longitudinal groove adapted to the round rod 32 is opened at the top of the sleeve 2. A round groove with an inner diameter larger than the inner diameter of the longitudinal groove is opened at the bottom of the longitudinal groove. A side groove with a width equal to its inner diameter is opened on one side of the inner wall of the longitudinal groove. A rectangular groove adapted to the cross bar 33 is opened on one side of the inner wall of the round groove. Both the side groove and the rectangular groove penetrate through the sleeve 2. During use, the warning sign 3 and the sleeve 2 are combined as a whole for use. The specific process is as follows:

[0027] First, move the cross bar 33 from the rectangular groove to the round groove, and move the round rod 32 from the side groove to the longitudinal groove. Then, move the cross bar 33, the round rod 32 and the warning board 31 downward, so that the cross bar 33 moves below the height of the rectangular groove, driving a part of the round rod 32 to also move below the height of the rectangular groove. At this time, the bottoms of the cross bar 33 and the round rod 32 are limited by the inner wall of the round groove, so they cannot move outside the sleeve 2, completing the assembly of the warning sign 3 and the sleeve 2. After the assembly is completed, it can be placed at the required place for use.

[0028] When it is necessary to carry the chemical safety warning sign, the staff moves the cross bar 33 upward to the rectangular groove, and then horizontally moves the cross bar 33 and the round bar 32, so that the cross bar 33 moves from the rectangular groove to the outside of the sleeve 2, and the round bar 32 moves from the side groove to the outside of the sleeve 2, separating the warning sign board 3 from the sleeve 2, and dividing the entire chemical safety warning sign into two parts with similar weights. The staff holds the sleeve 2 and the round bar 32 with both hands respectively, and moves the chemical safety warning sign to the designated location. It is possible to conveniently disassemble the assembled chemical safety warning sign, divide the warning sign with a relatively large overall weight into two parts with similar weights, and carry the two parts with their weights halved respectively. Compared with carrying the relatively large overall weight, the difficulty is smaller, which is convenient for the staff to hold with both hands to maintain balance and reduces the difficulty of moving the chemical safety warning sign to adjust its position.

[0029] In order to fix the warning sign board on the ground to prevent it from being pushed during use and release the fixation with the ground when it is necessary to carry it, so as to facilitate pushing it to move along the ground and reduce the difficulty of moving the warning sign board. In this embodiment, an adjustable structure is provided on the base 1. An elevating plate 4 is arranged inside the circular groove. A plurality of springs 5 are fixedly connected between the bottom of the elevating plate 4 and the inner wall of the circular groove. One end of the wear-resistant block 6 at the bottom of the elevating plate 4 movably penetrates through the base 1. When the warning sign board is in use, the weight of the warning sign board 3 presses down the elevating plate 4, causing the elevating plate 4 to descend to the bottom of the circular groove, squeezing and bending the springs 5. After the wear-resistant block 6 is pushed down by the elevating plate 4 to the bottom and contacts the ground, due to the friction between the wear-resistant block 6 and the ground, the universal wheels at the bottom of the base 1 cannot roll, and at this time, the base 1 cannot be pushed to move on the ground, achieving the purpose of fixing the warning sign board 3; when it is necessary to carry the warning sign board, since the warning sign board 3 is taken out from the inside of the sleeve 2, at this time, the elevating plate 4 is no longer pressed down by the warning sign board 3, and the springs 5 push the elevating plate 4 to rise, driving the wear-resistant block 6 to move towards the inside of the sleeve 2. At this time, after the wear-resistant block 6 rises, it no longer contacts the ground, and the universal wheels at the bottom of the base 1 can drive the base 1 to move along the ground. The contact mode between the base 1 and the ground can be flexibly adjusted. When the warning sign board is in use, the warning sign board is fixed to the ground to prevent the warning sign board from sliding on the ground. When it is necessary to carry it, the fixation between the warning sign board and the ground is released, which is convenient for pushing the warning sign board to move along the ground and reduces the difficulty of moving the warning sign board.

[0030] In order to prevent the warning sign 3 from rotating randomly during use, a structure for limiting the warning sign 3 is provided in this embodiment. A plurality of arc-shaped grooves intersecting at the center are opened at the top of the lifting plate 4, and the cross bar 33 extends movably into the arc-shaped grooves. During use, the cross bar 33 moves into one of the arc-shaped grooves at the top of the lifting plate 4, and the arc-shaped groove blocks the cross bar 33 from rotating in the circular groove, preventing the warning sign 3 from rotating randomly during use. When it is necessary to adjust the angle of the warning sign 3, the cross bar 33 is lifted upward to the outside of the arc-shaped groove, and then the cross bar 33, the round bar 32 and the warning board 31 are rotated until the cross bar 33 rotates into another arc-shaped groove at the top of the lifting plate 4, and then the cross bar 33 is lowered again into the arc-shaped groove at the top of the lifting plate 4, which can limit the angle of the warning sign 3 and at the same time facilitate the adjustment of the angle of the warning sign 3.

[0031] In order to facilitate the handling of the chemical safety warning sign by a single staff member after splitting the sleeve 2 and the warning sign 3, a structure for facilitating the staff member to hold the sleeve 2 is provided in this embodiment. An annular groove is opened on the outer side of the sleeve 2, and a rubber ring 7 is sleeved inside the annular groove. A notch adapted to the side groove is opened on one side of the rubber ring 7. During use, a staff member holds the round bar 32 with one hand and holds the annular groove of the sleeve 2 with the other hand. The rubber ring 7 reduces the extrusion of the staff member's hand by the sleeve 2, and then the staff member carries the warning sign 3 and the sleeve 2 to the designated location with both hands respectively, reducing the difficulty of a single staff member moving the chemical safety warning sign.

[0032] Embodiment Two

[0033] Although splitting the chemical safety warning sign into two parts with similar weights in Embodiment One has reduced the handling difficulty, the two parts still have a certain weight and require a lot of physical effort for handling. In order to further reduce the physical effort consumed in handling the chemical safety warning sign, this embodiment proposes another handling method. Refer to Figures 1-5, on the basis of the first embodiment, a hemisphere 8 adapted to the longitudinal groove is fixedly connected to one side of the warning board 31. A support assembly 9 for supporting the warning board 31 is provided outside the sleeve 2. The support assembly 9 includes a collar 91 that rotates along the fixed height of the sleeve 2. The collar 91 is sleeved outside the sleeve 2. A notch adapted to the side groove is formed on one side of the collar 91. An elastic plate 92 is fixedly connected to the top of the collar 91, and a cross column 93 is fixedly connected to the top of the elastic plate 92. During use, the hemisphere 8 on one side of the warning sign 3 is embedded into the top of the longitudinal groove. Then, the staff holds the cross bar 33 and gradually moves the cross bar 33 downward. After the warning board 31 contacts the cross column 93, the elastic plate 92 is gradually squeezed. The elastic plate 92 plays a supporting role for the warning sign 3. Then, the staff pushes the cross bar 33 horizontally, prompting the warning board 31 to push the sleeve 2 to move along the ground, so that the sleeve 2 can be used to support the warning sign 3, reducing the physical effort required to carry the sleeve 2 and the warning sign 3, and facilitating the movement of the chemical safety warning sign to the designated location.

[0034] When disassembling the sleeve 2 and the warning sign 3, it is necessary to rotate the collar 91 so that the notch of the collar 91 is aligned with the side groove to prevent the collar 91 from blocking the warning sign 3 from detaching from the sleeve 2.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
