[0002] Safety warning signs are commonly used in various types of construction projects to indicate dangerous work areas and alert relevant personnel to construction hazards. Existing safety warning signs are usually triangular in shape, including a back bracket and a triangular steel plate located in front of the back bracket, with a safety warning sign printed on the triangular steel plate. The safety warning signs of the aforementioned structure have the following defects: First, they take up more space and are relatively bulky, which is not conducive to transfer between different construction sites, nor is it conducive to storage and allocation for use; secondly, they are usually placed on the ground. In order to alleviate the problem of displacement, stones are usually used to press and fix the back bracket. However, in some application scenarios, factors such as strong winds usually cause the safety warning signs to shift or fall over, resulting in the loss of the safety warning function for specific locations.

[0003] In summary, it is necessary to develop and design a new type of safety warning sign to solve the above-mentioned technical problems. Utility Model Content

[0020] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0021] See also Figure 1 and Figure 2 The triangular safety warning sign of the utility model includes a first frame 1 and a second frame 15 which are arranged opposite to each other, a foldable inner bracket is installed between the two, and a flexible triangle sign 14 with a warning sign printed thereon, one side edge of the flexible triangle sign 14 is fixedly connected to the front facade of the first frame 1, and the other side edge of the flexible triangle sign 14 is fixedly connected to the front facade of the second frame 15.

[0022] The foldable inner bracket can be unfolded or folded, so the triangular safety warning sign can be converted between the unfolded state and the folded state. The unfolded state is the use state for producing a safety warning effect, and the folded state is the storage state. The flexible triangle sign 14 can be selected from a waterproof canvas material, and the overall structural strength is good and has a waterproof effect and good weather resistance. One side edge of the flexible triangle sign 14 can be fixedly connected to the first frame 1 by riveting or bonding, and the other side edge of the flexible triangle sign 14 can be fixedly connected to the second frame 15 by riveting or bonding. The flexible triangle sign 14 is stretched tight when the warning sign is in the unfolded state, and is shrunk and stacked when the warning sign is in the folded state.

[0023] In this embodiment, the foldable inner bracket includes a first long arm 6 and a second long arm 8 hingedly connected in the middle, a second short arm 10 is hingedly connected to the lower end of the first long arm 6, and a first short arm 5 is hingedly connected to the lower end of the second long arm 8. The upper ends of the first long arm 6 and the first short arm 5 are hingedly connected to the inner side of the first frame 1, and the upper ends of the second long arm 8 and the second short arm 5 are hingedly connected to the inner side of the second frame 15.

[0024] Figure 1 The figure shows the unfolded state, and it can be seen that: the first long arm 6 is parallel to the first short arm 5, and the second long arm 8 is parallel to the second short arm 10. The hinge position of the first long arm 6 and the first frame 1 is located in the middle front, the hinge position of the first short arm 5 and the first frame 1 is located in the middle rear, the hinge position of the second long arm 8 and the second frame 15 is located in the middle front, and the hinge position of the second short arm 10 and the second frame 15 is located in the middle rear.

[0025] In this embodiment, a first receiving groove is provided on the inner side of the first frame 1, and a second receiving groove is provided on the inner side of the second frame 15. Figure 2 As shown in the figure, the first long arm 6 and the first short arm 5 are respectively hingedly connected to the first frame 1 and the two sides of the first receiving groove, and the second long arm 8 and the second short arm 10 are respectively hingedly connected to the second frame 15 and the two sides of the second receiving groove. Therefore, the two sides of the folded foldable inner bracket fall into the first receiving groove and the second receiving groove respectively, which is conducive to further reducing the volume of the triangular safety warning sign after folding.

[0026] The foldable inner bracket is provided with a second support rod 11 and a first support rod 13 that can be unfolded and folded. A slot 12 is provided at the end of the second support rod 11 and the end of the first support rod 13 is located in the slot 12, so that the foldable inner bracket is kept in the unfolded state. In this embodiment, a first receiving groove 9 is provided at the lower part of the first long arm 6, an axial hole is provided at the root of the first support rod 13 and the hinge axis of the first long arm 6 and the second short arm 10 is located in the axial hole of the first support rod 13, and the first support rod 13 can be folded into the first receiving groove 9; a second receiving groove 7 is provided at the lower part of the second long arm 8, an axial hole is provided at the root of the second support rod 11 and the hinge axis of the second long arm 8 and the first short arm 5 is located in the axial hole of the second support rod 11, and the second support rod 11 can be folded into the second receiving groove 7. When the foldable inner support is fully unfolded, the end of the first support rod 13 is inserted into the slot of the second support rod 11, so that a triangular stable structure is formed in the middle and lower part of the foldable inner support, and the foldable inner support remains in the unfolded state without shrinking itself.

[0027] A first leg 2 is provided on the outside of the first frame 1 and the roots of the first leg 2 and the first frame 1 are hingedly connected. A second leg 16 is provided on the outside of the second frame 15 and the roots of the second leg 16 and the second frame 15 are hingedly connected. The first leg 2 and the second leg 16 can be unfolded and fixed backwards, and after unfolding, the main body of the safety warning sign can be supported on the ground. Figure 1 The figure shows a state where the first leg 2 is unfolded backwards and the second leg 16 is not unfolded backwards. It can be seen that in the folded state, the legs are folded and attached to the outer sides of the corresponding frames.

[0028] In this embodiment, the front of the first frame 1 and the second frame 15 are both provided with an end threaded hole 18, and the rear of both are both provided with a root threaded hole 19. The root of the first leg 2 is hingedly connected to the first frame 1 by a fastening screw 3 located in the root threaded hole 19, and the root of the second leg 16 is hingedly connected to the second frame 15 by a fastening screw 3 located in the root threaded hole 19. The fastening screw 3 has a collar. When the legs need to be unfolded, the fastening screw 3 is first loosened, and the legs are unfolded backward to a suitable position and then the fastening screw 3 is tightened. The collar provided on the fastening screw 3 helps to loosen and tighten the fastening screw 3.

[0029] In this embodiment, a threaded hole aligned with the threaded hole 18 at the end is provided at the other end of the first leg 2, and a fastening screw 3 is provided in the threaded hole. A threaded hole aligned with the threaded hole 18 at the end is provided at the other end of the second leg 16, and a fastening screw 3 is provided in the threaded hole. The fastening screw 3 has a collar. The two fastening screws 3 here have two functions: one function is to fix the folded leg to the outside of the frame on this side, and the other function is to use an anchor to anchor the collar of the fastening screw 3 when the leg is in the backward unfolded state and the leg falls on the ground, so as to achieve anchoring of the leg.

[0030] A first fixing ring 4 is provided on the outside of the root of the first frame 1, and a second fixing ring 17 is provided on the outside of the root of the second frame 15. The purpose of providing the first fixing ring 4 and the second fixing ring 17 is that when the safety warning sign is unfolded and placed on the ground, the first fixing ring 4 and the second fixing ring 17 are anchored by anchor nails to achieve anchoring of the roots of the two frames, and in conjunction with the aforementioned anchoring of the two legs, the safety warning sign can be stably anchored on the ground to avoid arbitrary displacement under the influence of wind force, etc.

[0031] As shown in Figure 3, this is the folded storage state of the safety warning sign. It can be seen that in the folded storage state, the foldable inner bracket is in a fully retracted state and the two sides are respectively located in the first storage groove of the first frame 1 and the second storage groove of the second frame 15. The first frame 1 is sufficiently close to the second frame 15, and the flexible triangle sign 14 is shrunk and stacked due to the lack of a propping effect.

[0032] It also includes a first elastic band 20 and a second elastic band 21. When the warning sign is completely folded, the first elastic band 20 is located between the two fastening screws 3 at the end, and the second elastic band 21 is located between the two fastening screws 3 at the root, so that the first frame 1 and its first leg 2, the second frame 15 and its second leg 16, and the flexible triangle 14 are limited to a folded state. In this way, the safety warning sign occupies less space, and is convenient for storage, allocation, use, and transfer between different construction sites.

[0033] Directions:

[0034] Initially, the safety warning sign is in Figure 3 When the foldable inner bracket is in the folded storage state shown in the figure, when it is transported to the construction site for use, the first elastic band 20 and the second elastic band 21 are first removed, and then the first frame 1 and the second frame 15 are pulled to the left and right sides to gradually unfold the foldable inner bracket, and at this time, the flexible triangle plate 14 is also gradually stretched out until it reaches Figure 1 In the fully expanded state shown in FIG, the first support rod 13 and the second support rod 11 are respectively pulled out of the storage slots and the end of the first support rod 13 is inserted into the slot 12 at the end of the second support rod 11;

[0035] Then, operate the two fastening screws 3 at the ends to release the connection between the end of the first leg 2 and the first frame 1 and the connection between the end of the second leg 16 and the second frame 15, unfold the first leg 2 and the second leg 16 backward to a suitable position and tighten the two fastening screws 3 at the root. At this time, the triangular safety warning sign can be placed on the ground, and the first leg 2 and the second leg 16 fall on the ground. Four anchor nails are driven into the ground to anchor the collars of the two fastening screws 3 and the first fixing ring 4 and the second fixing ring 17 respectively. Then, the safety warning sign is stably fixed on the ground, effectively preventing it from being displaced arbitrarily under the action of wind.

[0036] When the triangular safety warning sign needs to be moved, the anchors are removed, the first leg 2 and the second leg 16 are folded, and the two fastening screws 3 at the ends are tightened to combine the first leg 2 with the first frame 1, and the second leg 16 with the second frame 15; then the first frame 1 and the second frame 15 are squeezed toward the middle, the foldable inner bracket is contracted, and the flexible triangle sign 14 is contracted and stacked to achieve Figure 3 In the folded storage state shown in FIG, a first elastic band 20 is provided between the two fastening screws 3 at the end, and a second elastic band 21 is provided between the two fastening screws 3 at the root, so that the safety warning sign is limited to Figure 3 The folded storage state shown in FIG will not become loose on its own.
