Description

Technical Field

[0001] The utility model relates to the field of warning signs, and more specifically, to a temporary highway protection warning sign. Background Technique

[0002] Safety warning signs are used for the peripheral protection prompts of road construction sites, municipal construction maintenance, and building construction. They can be placed at the required places at any time to direct traffic, so as to prevent accidental impact events and reduce losses. At present, most of the existing temporary warning signs for highway construction protection on the market have poor fixing effects and are easily blown down by the wind. Moreover, because they are for temporary use and need to be carried and transferred, the existing warning signs have strong structural integrity and will occupy a large space, which is not convenient for transfer and use.

A rotating rod is fixedly connected to the bottom of the warning sign, and the rotating rod is rotatably connected to the fixed rod through a rotating pin. Openings are provided on both sides of the base, and a reinforcing plate is horizontally slidably inserted into the openings. A positioning pin for inserting and positioning the reinforcing plate is movably penetrated through the upper end of the base. A fixed seat is fixedly connected to the back of the fixed rod, and a positioning seat is fixedly connected to the back of the rotating rod. A threaded pin inserted into the positioning seat is threadedly penetrated through the fixed seat.

[0007] Preferably, a rubber pad for supporting on the ground is provided at the bottom of the base.

[0008] Preferably, a guide groove is horizontally provided on the inner wall of the opening. The inner wall of the guide groove is designed with a smooth surface structure, and a guide rail slidably matched with the guide groove is fixedly provided on the outer wall of the reinforcing plate.

[0009] Preferably, a first handle is fixedly connected to the upper end of the positioning pin, and the bottom of the first handle is connected to the upper end of the base through a contracted spring.

[0010] Preferably, an opening is further provided at the upper end of the reinforcing plate, and after the reinforcing plate is pulled out from the opening, the bottom of the positioning pin is inserted and matched with the opening at the upper end of the reinforcing plate.

[0011] Preferably, a second handle is fixedly connected to the bottom of the threaded pin. A positioning hole is vertically penetrated through the positioning seat, and the upper end of the threaded pin movably penetrates through the positioning hole.

[0012] 3. Beneficial effects

[0013] Compared with the prior art, the advantages of the present utility model are as follows:

[0014] By arranging and extending reinforcing plates on both sides of the base at the bottom of the warning sign, the overall support area is increased, thereby enhancing the overall support stability, ensuring the relative stability of the warning sign at the construction site and preventing it from being blown down by the wind. At the same time, the warning sign can be bent and stored, and the reinforcing plates can be inserted and stored, reducing the overall carrying and occupied space. Moreover, the installation operation during use is very simple, and the practical effect is relatively obvious, which is worthy of promotion and use in the existing market.

[0022] Please refer to Figures 1-3 , a temporary highway protection warning sign, including a base 1 and a warning sign 2. A fixed rod 3 is fixedly connected to the upper end of the base 1. A rotating rod 4 is fixedly connected to the bottom of the warning sign 2, and the rotating rod 4 is rotatably connected to the fixed rod 3 through a rotating pin 8. Openings 5 are provided on both sides of the base 1, and a reinforcing plate 6 is horizontally slidably inserted into the openings 5. A positioning pin 7 for inserting and positioning the reinforcing plate 6 is movably penetrated through the upper end of the base 1. A fixed seat 9 is fixedly connected to the back of the fixed rod 3, and a positioning seat 11 is fixedly connected to the back of the rotating rod 4. A threaded pin 10 inserted into the positioning seat 11 is threadedly penetrated through the fixed seat 9. A second handle 1001 is fixedly connected to the bottom of the threaded pin 10. A positioning hole is vertically penetrated through the positioning seat 11, and the upper end of the threaded pin 10 movably penetrates through the positioning hole. Based on the above structure, when the device is in use, as shown in the attached drawings of the specification Figure 3 , the staff rotates the warning sign 2 through the rotating pin 8 so that the fixed rod 3 and the rotating rod 4 are vertically butted and matched. Then, the second handle 1001 is rotated to drive the threaded pin 10 to rotate. The threaded pin 10 moves upward and is inserted into the positioning hole of the positioning seat 11. In this way, the fixed rod 3 and the rotating rod 4 can be kept longitudinally fixed, that is, the warning sign 2 is unfolded for warning use. Then, the reinforcing plate 6 in the opening 5 is pulled out to increase the overall support area, thereby increasing the overall support stability and preventing it from being blown down by the wind.

[0023] Among them, a rubber pad 101 for supporting on the ground is provided at the bottom of the base 1 to increase the friction of the contact, thereby increasing the auxiliary stability effect.

[0024] Among them, a guiding groove 501 is horizontally arranged on the inner wall of the opening 5, and the inner wall of the guiding groove 501 is designed with a smooth surface structure. A guiding rail 601 which is slidably matched with the guiding groove 501 is fixedly arranged on the outer wall of the reinforcing plate 6. The upper end of the positioning pin 7 is fixedly connected with a first handle 701. The bottom of the first handle 701 is connected to the upper end of the base 1 through a contracted spring. An opening is also arranged at the upper end of the reinforcing plate 6. After the reinforcing plate 6 is pulled out from the opening 5, the bottom of the positioning pin 7 is inserted and matched with the opening at the upper end of the reinforcing plate 6. Based on the above structure, two groups of openings are arranged at the upper end of the reinforcing plate 6. When it is necessary to stretch the reinforcing plate 6 for use, the staff first pulls the positioning pin 7 to move upward through the first handle 701 and simultaneously stretches the spring. The positioning pin 7 disengages from the opening at the upper end of the reinforcing plate 6 and releases the limit on the reinforcing plate 6. At this time, the reinforcing plate 6 is pulled to slide along the guiding groove 501 on the inner wall of the opening 5 until the positioning pin 7 is butted against another group of openings at the upper end of the reinforcing plate 6. At this time, the spring contraction drives the positioning pin 7 to be inserted into another group of openings at the upper end of the reinforcing plate 6, thereby positioning and fixing the reinforcing plate 6. The stretched reinforcing plate 6 can increase the supporting area of the base 1, thereby increasing the overall supporting stability.
