DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model. Example

[0022] Reference Figure 1-4 A foldable roadblock warning sign comprises two symmetrically arranged support rods 100, a connecting sleeve 101 which can move vertically along the outer wall of the support rod 100 is arranged on the outer wall of the support rod 100, a foldable support tripod 200 which can be stored and unfolded under the drive of the connecting sleeve 101 is also arranged between the outer wall of the connecting sleeve 101 and the side wall of the support rod 100, a connecting block 102 is arranged on the inner wall of the support rod 100, a foldable warning sign 300 is arranged on the connecting block 102, and a positioning mechanism 400 for limiting the distance between the two support rods 100 is also arranged between the two support rods 100. When carried, the roadblock warning sign is in a folded state. In the folded storage state, when in use, pull the connecting sleeve 101 and move downward along the support rod 100, so as to drive the supporting leg 200 connected thereto to unfold and play a good supporting effect. Then, release the limit positioning mechanism 400 to allow the warning sign to unfold. After releasing the limit, pull the two support rods 100 to move backwards to unfold the warning sign 300. Then, finally, the unfolded warning sign is limited and fixed by the positioning mechanism 400 to avoid the warning sign 300 rotating during use and failing to play a good warning effect. It should be noted that either the supporting leg 200 or the warning sign 300 can be unfolded first.

[0023] Reference Figure 1 , Figure 3 and Figure 4The supporting tripod 200 includes a first supporting plate 202 rotatably connected to the outer wall of the supporting rod 100 through a first connecting seat 201, and a second supporting plate 204 rotatably connected to the outer wall of the connecting sleeve 101 at one end through a second connecting seat 203 and hinged to the first supporting plate 202 at the other end. When in use, when the connecting sleeve 101 moves downward along the supporting rod 100, it will drive the second supporting plate 204 connected thereto to move downward and drive the first supporting plate 202 to rotate until the first supporting plate 202 is in horizontal contact with the ground. At this time, the supporting A triangular structure is formed between the rod 100, the first support plate 202 and the second support plate 204. Furthermore, support legs 200 are symmetrically arranged on both sides of each support rod 100, so that a good supporting effect can be formed when the support legs 200 are unfolded. Furthermore, when the roadblock warning sign is stored and folded, the connecting sleeve 101 is pulled upward along the support rod 100, which will drive the first support plate 202 and the second support plate 204 to rotate and move upward until they are in a vertical state and abut against the support rod 100, forming a stored state.

[0024] Reference Figure 1 , Figure 3 and Figure 4 , a positioning screw hole 103 is provided on the outer wall of the support rod 100, and the connecting sleeve 101 is connected to the support rod 100 by a locking bolt 104, and the locking bolt 104 is threadedly connected to the positioning screw hole 103. Specifically, two positioning screw holes 103 are provided along the upper and lower outer walls of the support rod 100. When the connecting sleeve 101 moves to the positioning screw hole 103 at the bottom and is fixed by the locking bolt 104, the first support plate 202 is in a horizontal state and can be well against the ground to play a good supporting effect. When the connecting sleeve 101 is at the top threaded hole 103 and is fixed by the locking bolt 104, the first support plate 202 and the second support plate 204 are both in a vertical state and against the support rod 100. At this time, the storage of the support tripod 200 is completed, so that it is easy to carry.

[0025] Reference Figure 1-3 There are several groups of warning signs 300, and two adjacent groups of warning signs 300 are hinged to each other. Specifically, several groups of warning signs 300 are hinged to each other and can be folded and stored together. When unfolded, they are large warning signs, and when stored, they are small warning signs. Therefore, they can achieve a good warning effect and can be folded for easy carrying. It should be noted that two adjacent groups of warning signs 300 can be folded to each other in a parallel state.

[0026] Reference Figure 1-3The positioning mechanism 400 includes two first fixing plates 401 arranged between the inner walls of the two support rods 100 and a second fixing plate 402 arranged between the two first fixing plates 401. The second fixing plate 402 is slidably connected to the two first fixing plates 401, and a fixing bolt 403 is arranged between the first fixing plate 401 and the second fixing plate 402. Specifically, when it is necessary to unfold or store the warning sign 300, the fixing bolt 403 is rotated to enable the first fixing plate 401 and the second fixing plate 402 to slide relative to each other, thereby ensuring that the warning sign 300 can be unfolded or folded. After unfolding or folding and storing, the fixing bolt 403 is rotated to prevent the first fixing plate 401 and the fixing plate 402 from moving relative to each other, thereby fixing the distance between the two support rods 100 and avoiding displacement between several groups of warning signs, thereby achieving a good fixing and limiting effect.

[0027] Reference Figure 1-3 In order to improve the warning effect of the warning sign, a reflective sticker 301 can be provided on the outer wall of the warning sign 300. Furthermore, a warning light and a buzzer can be provided on the outer wall of the warning sign 300.

[0028] Specifically, when the foldable roadblock warning sign is used: when in use, pull the connecting sleeve 101 to move downward along the support rod 100,

[0029] Thereby, the supporting tripod 200 connected thereto can be driven to unfold and play a good supporting effect. Subsequently, the positioning mechanism 400 of the limit is released so that the warning signs can be unfolded. After the limit is released, the two supporting rods 100 are pulled to move back to back to unfold the warning sign 300. Subsequently, the deployed warning sign is finally limited and fixed by the positioning mechanism 400 to avoid the warning sign 300 from rotating during use and failing to play a good warning effect. When the connecting sleeve 101 moves downward along the supporting rod 100, it will drive the second supporting plate 204 connected thereto to move downward and drive the first supporting plate 202 to rotate until the first supporting plate 202 is in horizontal contact with the ground. At this time, the supporting rod 100, the first supporting plate 202 and the second supporting plate 20 4 forms a triangular structure, and supporting legs 200 are symmetrically arranged on both sides of each supporting rod 100, so when the supporting legs 200 are unfolded, a good supporting effect can be formed, and two positioning screw holes 103 are arranged on the upper and lower outer walls of the supporting rod 100. When the connecting sleeve 101 moves to the positioning screw hole 103 at the bottom and is fixed by the locking bolt 104, the first supporting plate 202 is in a horizontal state and can be well offset against the ground to play a good supporting effect. When the connecting sleeve 101 is at the threaded hole 103 at the top and is fixed by the locking bolt 104, the first supporting plate 202 and the second supporting plate 204 are both in a vertical state and are offset against the supporting rod 100. At this time, the supporting legs 200 are stored for easy carrying.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
