DETAILED DESCRIPTION

[0022] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0023] See also Figure 1-5 A temporary warning device for highway maintenance includes a base 1. Two symmetrically arranged storage slots 2 are provided on both sides of the bottom of the base 1. Support plates 3 are rotatably connected within the storage slots 2. A total of four support plates 3 are provided at the bottom of the base 1. A first locking and limiting assembly 4 is provided at the top of the base 1, corresponding one-to-one with each support plate 3. After the four support plates 2 are rotated outward and deployed, they are fixed in place by the first locking and limiting assembly 4. After the four deployed support plates 3, the device can be better supported. A flip plate 5 is rotatably connected to both sides of the base 1 via a rotating shaft. Two symmetrically arranged moving wheels 6 are fixedly connected to the bottom of the flip plate 5. A second locking and limiting assembly 7 is provided between the flip plate 5 and the base 1. A fixing plate 8 is fixedly connected to the top of the base 1, a through slot is provided in the fixing plate 8, a driving motor 9 is arranged in the through slot, a threaded rod 10 is connected to the top output end of the driving motor 9, a warning plate 11 located above the fixing plate 8 is threadedly connected to the threaded rod 10, and a guide rod 12 located on both sides of the threaded rod 10 is fixedly connected to the top of the base 1, a sliding groove adapted to the guide rod 12 is provided at the bottom of the warning plate 11, and the guide rod 12 is slidably arranged in the sliding groove. Through the cooperation of the guide rod 12 and the sliding groove, the warning plate 11 can move up and down stably along the threaded rod 10.

[0024] Furthermore, a flexible pad 13 is fixedly connected to the bottom of the support plate 3. The flexible pad 13 is made of rubber. By providing the flexible pad 13, the friction between the bottom of the support plate 3 and the ground can be increased, thereby improving the support stability of the support plate 3.

[0025] Furthermore, the first locking limit assembly 4 includes an N-shaped frame 401 fixedly connected to the base 1, and a first insertion rod 402 is movably inserted into the N-shaped frame 401, and a first slot 403 adapted to the first insertion rod 402 is opened on the support plate 3, and a first limiting ring 404 located in the N-shaped frame 401 is fixedly connected to the surface of the first insertion rod 402, and a first spring 405 is provided between the top of the first limiting ring 404 and the N-shaped frame 401. When the support plate 3 is rotated inward to be completely retracted into the storage groove 2, the first insertion rod 402 will move downward under the cooperation of the first spring 405 and the first limiting ring 404 and be inserted into the first slot 403 to limit the support plate 3. When the support plate 3 is rotated outward to be fully extended, the first insertion rod 402 will move downward under the cooperation of the first spring 405 and the first limiting ring 404 and be fitted with one side edge of the support plate 3 to limit the support plate 3.

[0026] Furthermore, the second locking limit assembly 7 includes two second rods 701 movably inserted in the flip plate 5, the two second rods 701 are symmetrically arranged along the rotating axis, and a connecting rod 702 is fixedly connected to the outer ends of the two second rods 701. A second slot 703 adapted to the two second rods 701 is provided on one side of the base 1, and a second limiting ring 704 is fixedly connected to the second rod 701. A mounting groove 705 adapted to the second limiting ring 704 is provided inside the flip plate 5, and a second spring 706 sleeved on the second rod 701 is provided in the mounting groove 705. The second spring 706 is located on the side of the second limiting ring 704 away from the base 1. When it is necessary to flip the moving wheel 6 upward, the connecting rod 702 is pulled outward to drive the two second insertion rods 701 to move outward and disengage from the second slot 703, thereby releasing the limit fixation of the flip plate 5, and then the flip plate 5 is rotated 180° to make the moving wheel 6 leave the ground and rotate upward, and then the connecting rod 702 is loosened. With the cooperation of the second spring 706 and the second limiting ring 704, the second insertion rod 701 will be driven to be reinserted into the second slot 703 to limit and fix the flip plate 5.

[0027] Furthermore, both sides of the warning plate 11 are provided with limit grooves 14 corresponding to the guide rods 12, and the limit grooves 14 are conductively connected to the adjacent slide grooves. The top proximal end of the guide rod 12 is fixedly connected to the limit block 15, and the limit block 15 is slidably set in the corresponding limit groove 14. By setting the limit grooves 14 and the limit blocks 15, the warning plate 11 can be limited to prevent the guide rod 12 from disengaging from the slide groove when the warning plate 11 is adjusted upward in height, causing the warning plate 11 to fall.

[0028] When in use, the device is moved to the warning position by the moving wheel 6, and then the first plug rod 402 is pulled upwards to make the first plug rod 402 disengage from the first slot 403, releasing the limit fixation of the support plate 3, and then the support plate 3 is rotated outward to open. When the support plate 3 is rotated outward to be fully expanded, the first plug rod 402 will move downward under the cooperation of the first spring 405 and the first limiting ring 404 and fit into the side edge of the support plate 3 to limit and fix the support plate 3. According to the above operation, the four support plates 3 are opened and then fixed. When the four support plates 3 are all expanded, the connecting rod 702 is pulled outward to drive the two second plug rods 701 to move outward and disengage from the second The slot 703 is used to release the limit fixation of the flip plate 5, and then the flip plate 5 is rotated 180 degrees, so that the moving wheel 6 is off the ground and rotated upwards, and then the connecting rod 702 is loosened. With the cooperation of the second spring 706 and the second limiting ring 704, the second insertion rod 701 will be driven to be reinserted into the second slot 703, and the flip plate 5 is limited and fixed, so that the support plate 3 can contact the ground and play a supporting role. When the warning height of the warning plate 11 needs to be adjusted, the threaded rod 10 is driven by starting the drive motor 9 to rotate clockwise or counterclockwise, thereby driving the warning plate 11 to move upward or downward, so as to quickly adjust the warning height of the warning plate 11.
