Detailed ways

The utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without any creative efforts shall fall within the scope of protection of the present utility model.

Example 1

Referring to Figure 1-4, a road construction warning sign includes two hinged display frames. The display frame is composed of a panel 16, a cover plate 9, a bottom plate 15, a side plate 6 and a rear plate 8. The two display frames The body is hingedly arranged with the help of a rotating member. The rotating member includes a sleeve 2 provided with two hollow inner cavities. The upper and lower ends of the hollow inner cavity are welded with rotating bearing seats 3. The rotating shaft 4 penetrates the hollow inner cavity and extends out of the rotating bearing at both ends. The base 3 and the upper and lower ends of the rotating shaft 4 are provided with limiting blocks 5. The upper and lower ends of the side plates 6 are provided with connecting plates 7 that are hinged with the rotating shaft 4. The connecting plates 7 are sleeved on the bearing seat 3 and the limiting blocks 5. Between them, the two display frames rotate at multiple angles with the help of the rotating shaft 4. Each display frame rotates with the help of a rotating shaft and does not affect each other. This increases the rotational freedom of the display frame and makes the rotation of the display frame easier. Compared with sharing a rotating axis, the degree of freedom is not limited, and the two panels can be folded inward to achieve the function of protecting the panels. The connecting plate 7 is arranged between the transfer seat 3 and the limiting block 5, which can limit the connection plate 7. The transfer seat 3 is provided to provide support for the connecting plate 7 on the one hand, and to avoid the connecting plate 7 on the other hand. 7 rubs against the shaft sleeve 2 over a large area to improve rotational flexibility. The limit block 5 at the lower end of the rotating shaft 4 also serves to support the rotating shaft 4 and the connecting plate 7 below.

A dovetail groove with a height of 1/3 of the rear plate and a matching detachable limiting fixing block are provided above the rear plate 8 of the display frame. The dovetail groove can improve the fixed limit of the unfolded state of the display frame. For positioning function, the dovetail groove structure is used to increase the limit and fixing strength and have good stabilizing effect. In addition, when the two display frames are used at an angle (such as an acute angle or an obtuse angle, which is not 180° flattened), the dovetail fixation of this utility model The structure can have a better fixing effect on stabilizing angles.

Furthermore, the detachable limit fixture is designed to be a telescopic detachable limit fixture, including a telescopic rod 10 and a fixed block 11 that is rotationally connected to the telescopic rod 10. Its length can be adjusted through the telescopic rod 10 to facilitate installation at different intervals. The dovetail groove is fixed and is designed to be telescopic for convenient storage; the rotational connection allows the fixed block 11 to rotate around the end of the telescopic rod 10, such as using a pin connection.

Further, a storage unit for storing the detachable limiting fixing block is provided on the rear panel 8 of the display frame. The storage unit can be a storage bag hung on the rear panel 8 .

Furthermore, a fluorescent layer is provided on the surface of the shaft sleeve 2 to improve the warning effect at night.

Furthermore, the thickness of the sleeve 2 is smaller than the width of the cover 9, which can facilitate the removal of the cover 9; the distance between the axes of the two rotating shafts 4 is greater than the width of the base, ensuring that the two display frames can be folded.

Furthermore, the base is a fixed base 13 connected to the display frame by means of a telescopic column 12. A counterweight block is provided in the fixed base 13. The base is designed as a telescopic structure. By adjusting the telescopic amount of the telescopic column 12, on the one hand The height of the warning sign can be adjusted. On the other hand, when the warning sign is not in use, adjusting the telescopic column 12 to the shortest length can greatly reduce the space occupied by the warning sign, further solving the problem of the warning sign occupying space. The telescopic column 12 is connected with the display. The frame is connected to the side away from the hinged end, and the bottom end of the telescopic column 12 is connected to the fixed base 13, and its support stability is increased by a counterweight set in the fixed base 13.

Furthermore, a fluorescent layer is provided on the surface of the telescopic column 12, which can improve the warning effect at night.

Further, a light trough is set up on the inner wall of the display frame, and an LED light group 14 (such as a photosensitive LED light, an ordinary LED light, a voice-activated LED light, etc.) is provided inside. A solar panel is provided above the display frame. The solar panel The output end of the battery is connected to the input end of the battery, and the output end of the battery is connected to the input end of the LED light group 14. It absorbs sunlight through the solar panel, and then converts it into electrical energy and outputs it to the battery to supply to the LED light group 14, which is energy-saving and efficient; The LED lamp set 14 can also be powered directly through an external battery.

Further, the cover plate 9 and the bottom plate 15 are both provided with card slots, and the panel 16 is slidably connected to the cover plate 9 and the bottom plate 15 through the card slots. When it is necessary to replace the information display panel 1 in the display frame, the panel 16 is slidably connected to the cover plate 9 and the bottom plate 15 through the card slots. Slide the slot out, and after replacing the information display panel 1, slide the panel 16 in through the slot to facilitate the replacement of the information display panel 1. The card slot is a groove with rollers, and the panel is made of transparent anti-reflective acrylic plate, which can prevent reflection and avoid the disadvantages of unclear visibility of warning signs due to reflection or dizziness.
