DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 3 As shown, the utility model provides a safety protection warning sign device, including a base 1, an unfolding device 2, a mounting plate 3 and a warning sign 4. The bottom of the unfolding device 2 is fixedly connected to the top of the base 1, and the bottoms on both sides of the mounting plate 3 are movably connected to the front and rear sides of the top of the base 1 through axle pins. The surface of the warning sign 4 is slidably connected to the inner wall of the mounting plate 3, and both sides of the outer side of the mounting plate 3 are slidably connected with L-shaped plates 5. The inner side of the outer side of the L-shaped plate 5 is inclined, and tension springs 6 are provided on both sides of the inner side of the mounting plate 3. The two ends of the tension spring 6 are fixedly connected to the top and bottom of the inner side of the L-shaped plate 5. The inner side of the mounting plate 3 is fixedly connected to the limiting component 7, and the outer sides of the front and back of the L-shaped plate 5 are movably connected to the fixing component 8 through axle pins.

[0023] refer to Figure 1 and Figure 2 The limiting component 7 includes a trapezoidal rod 71, the outer side of the trapezoidal rod 71 is fixedly connected to the inner side of the mounting plate 3, and a trapezoidal groove 72 is opened on the inner side of the front and back of the L-shaped plate 5. The two ends of the surface of the trapezoidal rod 71 are slidably connected to the inner wall of the trapezoidal groove 72.

[0024] As a technical optimization solution of the present invention, by setting a limit assembly 7, when the L-shaped plate 5 is squeezed by the warning sign 4 and moves symmetrically outward, the trapezoidal groove 72 moves along the trajectory of the trapezoidal rod 71 at the same time. Then, through the cooperation between the trapezoidal rod 71 and the trapezoidal groove 72, the position of the L-shaped plate 5 is stably maintained in the center position of the mounting plate 3, thereby stabilizing the effect of the L-shaped plate 5 when the warning sign 4 is stuck in the mounting plate 3.

[0025] refer to Figure 1 and Figure 2 The fixing assembly 8 includes a fixing block 81, which is movably connected to the outside of the front and back sides of the L-shaped plate 5 through an axle pin, and a slot 82 is provided on the outside of the top of the trapezoidal rod 71.

[0026] As a technical optimization solution of the present invention, by setting a fixing component 8, when it is necessary to replace the warning sign 4 in the mounting plate 3 with a warning sign 4 with a different marking, first pull the L-shaped plate 5 until the L-shaped plate 5 is out of contact with the warning sign 4, then rotate the fixing block 81, and snap the fixing block 81 into the slot 82 of the trapezoidal rod 71, so that the L-shaped plate 5 is limited, and the rebound force of the tension spring 6 cannot pull the L-shaped plate 5 to reset, and then the warning sign 4 can be disassembled and replaced, thereby facilitating the user to replace the warning sign 4.

[0027] refer to Figure 3 The outer side of the inner wall of the slot 82 is inlaid with balls 9, and a plurality of balls 9 are provided and distributed at equal distances.

[0028] As a technical optimization solution of the present invention, by providing the ball 9, when the user rotates the fixing block 81 to engage in the slot 82, the ball 9 will replace the outer side of the inner wall of the slot 82 to contact the outer side of the fixing block 81. Subsequently, when the warning sign 4 in the mounting plate 3 is replaced and the fixing block 81 is rotated out of the slot 82, the ball 9 will rotate in contact with the fixing block 81, thereby reducing the friction resistance and preventing the rebound force of the tension spring 6 from continuously pulling the L-shaped plate 5 to reset, causing the outer side of the inner wall of the slot 82 and the outer side of the fixing block 81 to be too large to make the fixing block 81 difficult to rotate, thereby improving the user's operating convenience.

[0029] refer to Figure 2 The outer side of the fixed block 81 is fixedly connected to the first magnetic block 10, the outer side of the first magnetic block 10 is magnetically adsorbed with the second magnetic block 11, and the inner side of the second magnetic block 11 is fixedly connected to the outer sides of the front and back sides of the L-shaped plate 5.

[0030] As a technical optimization solution of the present invention, by setting the first magnetic block 10 and the second magnetic block 11, when there is no need to use the fixed block 81 to snap into the slot 82, the fixed block 81 is rotated until the first magnetic block 10 and the second magnetic block 11 are in contact, and magnetically adsorbed, so that the fixed block 81 is limited and fixed, thereby preventing the L-shaped plate 5 from being squeezed by the warning sign 4 and then the L-shaped plate 5 is pulled back to its original position by the rebound force of the tension spring 6 to snap the warning sign 4 into the mounting plate 3. The fixed block 81 rotates and snaps into the slot 82 by itself, affecting the release of the rebound force of the tension spring 6, thereby improving the user's operating convenience.

[0031] refer to Figure 1 Both sides of the inner side of the mounting plate 3 are fixedly connected with a U-shaped frame 12, and the inner side of the U-shaped frame 12 is slidably connected to both sides of the unfolding device 2.

[0032] As a technical optimization solution of the present invention, a U-shaped frame 12 is provided to replace the mounting plate 3 in contact with the unfolding device 2, thereby preventing the tension spring 6 and the trapezoidal rod 71 from blocking the opening of the unfolding device 2 when the unfolding device 2 is started to unfold the mounting plate 3, thereby improving the smoothness of the unfolding device 2 when the unfolding device 2 unfolds the mounting plate 3.

[0033] refer to Figure 2 Positioning blocks 13 are fixedly connected to both sides of the inner side of the trapezoidal rod 71.

[0034] As a technical optimization solution of the present invention, by setting a positioning block 13, when a warning sign 4 with different markings needs to be replaced in the mounting plate 3, the user pulls the L-shaped plate 5 to move until it is out of contact with the warning sign 4. The pulling distance of the L-shaped plate 5 is limited by the positioning block 13, and then the fixing block 81 can be quickly positioned when it is rotated into the card slot 82, thereby improving the user's work efficiency.

[0035] The working principle and usage process of the present invention are as follows: when it is necessary to make warning signs around the construction site, the user finds a warning sign 4 that matches the current construction project and construction site, then holds the warning sign 4, aligns the warning sign 4 with the inner wall of the mounting plate 3, and then fits the two sides of the warning sign 4 with the inclined surfaces of the L-shaped plate 5 and presses, so that the L-shaped plate 5 gradually moves outward symmetrically and generates a rebound force when the tension spring 6 is stretched. At the same time, the trapezoidal groove 72 moves along the trajectory of the trapezoidal rod 71 at the same time. Through the cooperation of the trapezoidal rod 71 and the trapezoidal groove 72, the L-shaped plate 5 is stabilized and maintained in the center position of the mounting plate 3. Then, when the warning sign 4 is completely stuck in the inner wall of the mounting plate 3, the rebound force of the tension spring 6 will be instantly released, pulling the L-shaped plate 5 to reset, thereby firmly fixing the warning sign 4 When the warning sign 4 is stuck in the mounting plate 3, the unfolding device 2 can be started to unfold the mounting plate 3, and then the warning sign 4 can be used to warn passers-by. Then, when the construction projects at the construction site are different and the warning sign 4 with different warning signs needs to be replaced, the L-shaped plate 5 is pulled until the L-shaped plate 5 is out of contact with the warning sign 4, the fixing block 81 is rotated, and the fixing block 81 is stuck in the slot 82 of the trapezoidal rod 71, and finally the L-shaped plate 5 is limited, so that the rebound force of the tension spring 6 cannot pull the L-shaped plate 5 to reset, and finally the warning sign 4 in the mounting plate 3 can be replaced. Finally, when the replacement is completed, it is only necessary to rotate the fixing block 81 out of the slot 82 to release the rebound force of the tension spring 6, pull the L-shaped plate 5 back to its original position, and jam the warning sign 4, thereby having the advantage of assisting replacement and installation.

[0036] To sum up: the safety protection warning sign device, by setting an L-shaped plate 5 and a tension spring 6, when the warning sign 4 needs to be installed into the mounting plate 3, the two sides of the warning sign 4 are fitted and pressed against the inclined surfaces of the L-shaped plate 5, so that the L-shaped plate 5 gradually moves symmetrically outward, causing the tension spring 6 to be stretched and produce a rebound force, and then when the warning sign 4 is completely stuck in the mounting plate 3, the rebound force of the tension spring 6 pulls the L-shaped plate 5 to return to its original position, jamming the warning sign 4, solving the problem that the construction environment and construction projects are different, the required warning signs are different, and the reminder purposes are different. However, in the above-mentioned equipment, the warning plate is directly fixed to the mounting plate by glue or bolts, which is inconvenient to replace, thereby reducing the practicality of the above-mentioned equipment.
