Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0021] See Figures 1-3 This utility model provides a traffic warning sign, including:

[0022] The bow-shaped frame 1 is hollow inside. A holding crossbar 11 is fixedly connected to the bow-shaped frame 1. A fixed shaft 12 is fixedly connected to the bow-shaped frame 1 below the holding crossbar 11. Two warning plates 2 are rotatably connected to the fixed shaft 12. The two warning plates 2 are symmetrically arranged with respect to the bow-shaped frame 1. The top of each warning plate 2 is rotatably connected to the fixed shaft 12. A torsion spring is provided at the connection between the warning plate 2 and the fixed shaft 12. When the torsion spring is in its natural state, the two warning plates 2 move closer to each other, and the device is in a retracted state.

[0023] Two support links 3 are provided, each rotatably mounted at the bottom of the warning plate 2. Each support link 3 is rotatably connected to a corresponding warning plate 2, and the ends of adjacent support links 3 are hinged together. When the warning plate 2 changes from a retracted state to an extended state, each support link 3 rotates around its connection point with the warning plate 2. When both warning plates 2 are extended to their maximum extent, both support links 3 are horizontal. One of the hinged support links 3 has a locking sleeve 31 slidably mounted on it. When the support link 3 rotates to a horizontal position, the locking sleeve 31 is slidably placed at the hinge point of the two support links 3, thus limiting the position of the support link 3 and forcing it to remain horizontal, thereby restricting the extended state of the warning plate 2.

[0024] There are two bottom rotating shafts 4, both of which are rotatably connected to the warning plate 2. The bottom rotating shafts 4 and the warning plates 2 are matched one-to-one. Both ends of the bottom rotating shafts 4 are rotatably connected to the supports, and the supports are fixedly connected to the warning plates 2. Each bottom rotating shaft 4 is provided with a bottom slider 42, which is slidably connected to the warning plate 2. The bottom rotating shaft 4 is provided with a bottom spiral groove that cooperates with the bottom slider 42. When the bottom slider 42 moves along the bottom rotating shaft 4, it can drive the bottom rotating shaft 4 to rotate. The bottom end of each bottom rotating shaft 4 is fixedly connected to an auxiliary support rod 41. The warning plate 2 has a clearance groove on its side wall that cooperates with the support rod 3. The ends of the support rod 3 are rotatably connected to the side wall of the clearance groove. The side wall of the warning plate 2 below the bottom slider 42 is fixedly connected to a fixed seat 21. Several springs are provided between adjacent fixed seats 21 and bottom slider 42. The two ends of the springs are respectively connected to the fixed seat 21 and the bottom slider 42. When the warning plate 2 is in the retracted state, the support rod 3 does not contact the bottom slider 42. At this time, the spring is in the natural state, and the auxiliary support rod 41 is located between the two warning plates 2.

[0025] The rotating handle 5 is rotatably connected to the bow-shaped frame 1. The bow-shaped frame 1 has a break at the middle of its top end. The rotating handle 5 is rotatably connected to the break at the bow-shaped frame 1. Both ends of the rotating handle 5 are fixedly connected to the top rotating shaft 51, which passes through the bow-shaped frame 1. The bow-shaped frame 1 on both sides of the rotating handle 5 is slidably connected to the top slider 6. The top slider 6 and the top rotating shaft 51 are correspondingly matched. The top rotating shaft 51 is provided with a top spiral groove that matches the top slider 6. When the rotating handle 5 is turned, the top slider 6 can reciprocate along the top rotating shaft 51 under the action of the top spiral groove because the top slider 6 is slidably connected to the bow-shaped frame 1.

[0026] A limiting horizontal bar 14 is located below the fixed shaft 12 and is fixedly connected to the bow-shaped frame 1. Adjustable sliders 7 are slidably fitted at both ends of the limiting horizontal bar 14. Connecting straps 61 connect adjacent adjustable sliders 7 and top sliders 6, with both ends of the connecting straps 61 fixedly connected to the adjustable sliders 7 and top sliders 6 respectively. When the two top sliders 6 approach each other, they can drive the two adjustable sliders 7 away from each other. Two symmetrical push rods 8 are rotatably connected to both ends of the bottom of the bow-shaped frame 1. Adjusting connecting rods 71 ​​are rotatably connected between the adjacent adjustable sliders 7 and the push rods 8. One end of the adjusting connecting rod 71 is rotatably connected to the adjustable slider 7, and the other end is rotatably connected to the push rod 8. When the two adjusting connecting rods 71 ​​move away from each other, under the action of the adjusting connecting rods 71, they can drive the push rod 8 to rotate around its connection point with the bow-shaped frame 1, thereby pushing the two warning plates 2 to unfold.

[0027] See Figures 1-3 Preferably, both sides of the bow-shaped frame 1 are fixedly connected with guide passages 13 that cooperate with the connecting strap 61, which can guide and limit the connecting strap 61 and prevent the connecting strap 61 from getting tangled.

[0028] See Figures 1-3 Preferably, the limiting horizontal bar 14 is used to support and limit the adjusting slider 7. Specifically, the limiting horizontal bar 14 can be a square, triangular or elliptical cylindrical structure, etc., which can prevent the adjusting slider 7 from rotating. Users can also add several limiting rods passing through the adjusting slider 7 next to the limiting horizontal bar 14 to achieve limiting.

[0029] See Figures 1-3 Preferably, the surface of the rotating grip 5 is provided with anti-slip texture, which can improve the friction between the user's hand and the rotating grip 5, making it easier for the user to turn the rotating grip 5.

[0030] During use, the user holds the horizontal bar 11 with one hand and rotates the handle 5 with the other. Rotating the handle 5 causes the top rotating shaft 51 fixed at both ends to rotate. Since the top slider 6 is slidably connected to the bow-shaped frame 1, the two top sliders 6 move closer to each other. Under the action of the connecting belt 61, the two adjusting sliders 7 move further apart. Under the action of the adjusting connecting rod 71, the push rod 8 rotates and pushes the warning plate 2 from the retracted state to the unfolded state.

[0031] During the rotation of the warning plate 2, the support rod 3 rotates with its connection point with the warning plate 2 as the center. Initially, the support rod 3 does not contact the bottom slider 42. When there is a certain gap between the two warning plates 2, the support rod 3 abuts against and presses down on the bottom slider 42, causing the bottom slider 42 to move a certain distance along the bottom rotating shaft 4. Under the action of the bottom spiral groove, the bottom rotating shaft 4 rotates 180°, causing the auxiliary support rod 41 to rotate out. Then, the user places the device on the ground and moves the locking sleeve 31 to the connection point of the two support rods 3 to complete the locking of the warning plate 2.

[0032] This utility model provides a traffic warning sign, which has the following beneficial effects:

[0033] 1. By setting up a rotating handle, top pivot, top slider and adjusting slider, the warning board can be automatically unfolded when the rotating handle is turned, which reduces the labor intensity of the user, reduces the number of steps to use the warning board, and makes it easier to use.

[0034] 2. By setting up a support link, locking sleeve, bottom pivot, and auxiliary support rod, the warning board can be locked in its unfolded state, and the auxiliary support rod can be automatically rotated out during the unfolding process of the warning board, thereby providing auxiliary support for the warning board, reducing the risk of tilting, and improving the safety of use.

[0035] In summary, the beneficial effects of this utility model are as follows: it can automatically unfold the warning board by twisting the handle, and during the unfolding process, it can also drive the auxiliary support rod to automatically rotate out, providing auxiliary support for the warning board, reducing the risk of the warning board tilting, and improving the safety of use.

[0036] Of course, there may be many other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
