Description

Technical Field

[0001] The utility model relates to the technical field of road warning signs, in particular to a road warning sign. Background Art

[0002] The triangular warning sign for cars is made of plastic reflective material as a passive reflector. When the driver stops to repair a sudden breakdown or an accident occurs on the road, the driver can use the triangular warning sign's reflective properties to remind other vehicles to give way to avoid a secondary accident.

[0003] In order to facilitate the carrying of the warning triangle and reduce the area occupied by the warning triangle, the warning triangle is made into a foldable structure, and when it is needed, the warning triangle is unfolded. At present, the warning triangle includes a triangular reflector and a bracket supporting the reflector. In order to enhance the stability of the warning triangle, the bracket includes two cross-arranged mounting strips. When in use, the two mounting strips are adjusted to a cross shape and unfolded to increase the area of ​​the base, thereby improving the stability of the warning sign. Although this warning sign has a simple structure, the reflector still occupies a large area.

[0004] Therefore, the utility model patent with authorization announcement number CN218141279U discloses a triangular pyramid-type wind-resistant and high-brightness triangular warning sign, which improves the stability of the warning sign by fully unfolding the first supporting strip, the second supporting strip, and the third supporting strip and cooperating with the sharp corners to form a triangular pyramid, and then unfolding the first folding strip and the second folding strip to further enhance the stability of the warning sign and prevent the unfolded warning sign from returning to its original state.

[0005] Although the warning sign in the above-mentioned solution can be folded to reduce the floor space and improve the stability of the warning sign, the warning sign in the solution is relatively complicated in the unfolding and folding process and is inconvenient to use.

[0006] Therefore, how to design a road warning sign that is convenient to unfold or fold has become a technical problem that needs to be solved urgently by people in this field. Utility Model Content

Detailed Embodiment

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] This embodiment provides a road warning sign, which improves the stability of the warning sign and at the same time facilitates the unfolding or folding of the warning sign, making it convenient to operate.

[0030] The road warning sign in this embodiment refers to a triangular warning sign for automobiles, which facilitates the operation of unfolding or storing the warning sign, and at the same time improves the stability of the warning sign during use, preventing the situation that the high-speed passing of the automobile drives the airflow to blow over the warning sign.

[0031] As Figure 1 shown, the road warning sign includes a mounting base 10, a first reflector 11, a second reflector 12 and a support plate 13. Among them, both the first reflector 11 and the second reflector 12 are hinged to the mounting base 10 and can be unfolded along the left-right direction; when in use, the reflective surfaces of the first reflector 11 and the second reflector 12 face the oncoming vehicle, bringing a warning effect to the drivers of other vehicles; in order to enhance the stability of the warning sign, the support plate 13 is hinged to the mounting base 10 and can be unfolded along the front-back direction; after the warning sign is unfolded, as Figure 1 shown, at this time, the mounting base 10, the first reflector 11, the second reflector 12 and the support plate 13 form a triangular pyramid shape with the opening facing downwards. At this time, the support plate 13 abuts against the ground, which can improve the stability of the warning sign and reduce the possibility of the warning sign being blown over by the airflow.

[0032] In order to further enhance the stability of the unfolded warning sign and facilitate the driver of the oncoming vehicle to see the light reflected by the reflector, the folding angle of the support plate 13 needs to be restricted. In this embodiment, as Figure 4 and Figure 6 shown, the top end of the support plate 13 is provided with a bent limiting plate 132. When the warning sign is unfolded, the limiting plate 132 on the support plate 13 abuts against the upper wall of the mounting base 10, restricting the continuous flipping of the support plate 13. At this time, the included angle between the reflector and the vertical direction perpendicular to the ground is 30°, which is convenient for reflecting the light to the drivers of other vehicles.

[0033] In order to prevent the included angle between the support plate 13 and the mounting base 10 from changing after the warning sign is toppled, in this embodiment, as Figure 6 shown, the upper wall of the mounting base 10 is provided with a downwardly concave locking hole 102, and a locking head 133 made of rubber is fixedly installed on the limiting plate 132. After the warning sign is unfolded, the locking head 133 is inserted into the locking hole 102 to lock the support plate 13 and the mounting base 10, enhancing the stability of the support plate 13 and the mounting base 10.

[0034] In order to realize the installation of the support plate 13, as Figure 4 and Figure 6As shown, a support seat 101 is fixedly mounted on the rear wall of the mounting seat 10 , wherein a connecting seat 131 is fixedly mounted on the supporting plate 13 , and the connecting seat 131 is hinged to the support seat 101 via a rotating shaft.

[0035] Under normal circumstances, the first reflector 11 and the second reflector 12 of the warning sign need to be manually handled when unfolding. Figure 2 , Figure 3 and Figure 5 As shown, the bottom of the first reflector 11 is hinged with a first hinged rod 21 through a first rotating shaft 211, and the bottom of the second reflector 12 is hinged with a second hinged rod 22 through a second rotating shaft 221, wherein the first hinged rod 21 is hinged with the end of the second hinged rod 22, and a spring 3 is sleeved at the hinged portion of the first hinged rod 21 and the second hinged rod 22, wherein the two ends of the spring 3 are fixedly connected to the first hinged rod 21 and the second hinged rod 22, respectively. When the warning sign is in a folded state, as shown in FIG. Figure 3 As shown, at this time, the hinge point of the first hinge rod 21 and the second hinge rod 22 is offset to one side of the mounting seat 10, and the spring 3 is bent. When the first reflector 11 and the second reflector 12 need to be unfolded, the spring 3 will be quickly straightened to make the axes of the first hinge rod 21 and the second hinge rod 22 coincide. At this time, the first hinge rod 21 and the second hinge rod 22 are used to open the first reflector 11 and the second reflector 12 to achieve rapid unfolding of the warning sign.

[0036] In order to further improve the reflective effect, a third reflector 14 is fixedly provided on the front side of the first hinge rod 21 , and a fourth reflector 15 is fixedly provided on the front side of the second hinge rod 22 , thereby increasing the reflected light and improving the reflective effect.

[0037] When the warning sign needs to be folded and stored, in order to prevent the spring 3 from unfolding the first reflector 11 and the second reflector 12, in this embodiment, the positions of the first reflector 11 and the second reflector 12 need to be limited, specifically, as follows: Figure 1 , Figure 3 and Figure 5 As shown, a snap-fit ​​plate 5 is fixedly provided on the front wall of the support plate 13, and a snap-fit ​​groove 51 is provided on the snap-fit ​​plate 5. The rear walls of the first reflector 11 and the second reflector 12 are both fixedly provided with snap-fit ​​columns 4. When the warning sign is in a folded state, the snap-fit ​​column 4 is snapped into the snap-fit ​​groove 51, thereby preventing the spring 3 from unfolding the reflector.

[0038] It is worth noting that the buckling plate 5 is made of rubber material, which facilitates the buckling column 4 to be inserted into the buckling groove 51 .

[0039] When the warning sign is in use, the support plate 13 is folded backward, so that the fastening column 4 is disengaged from the fastening groove 51. Under the elastic force of the spring 3, the first reflector 11 and the second reflector 12 are quickly unfolded. By continuing to fold the support plate 13, the locking head 133 is fastened in the locking hole 102, thus realizing the full unfolding of the warning sign. When it is necessary to fold and store the warning sign, the first hinge rod 21 and the second hinge rod 22 are respectively rotated around the first rotating shaft 211 and the second rotating shaft 221. The hinge joints of the first hinge rod 21 and the second hinge rod 22 move towards the mounting seat 10 side, bending the spring 3, removing the locking head 133 from the locking hole 102, and then fastening the fastening column 4 on the first reflector 11 and the second reflector 12 inside the fastening groove 51, thus completing the folding and storage of the warning sign. The unfolding and storage methods of this warning sign are more convenient than the prior art and are convenient for the driver to operate.

[0040] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
