DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-4 The utility model provides a technical solution: a combined traffic guardrail, comprising: a column 1 which is hollow inside and has an upper end opening, the lower end of the column 1 is connected to the ground by bolts, the upper end of the column 1 is sleeved with a top cover 2, the lower end area of the top cover 2 is larger than the area of the upper end opening of the column 1 and the upper end is sloped, the left and right sides of the column 1 are provided with sockets 3 in an array, a guardrail 4 is arranged between the two columns 1, and three connecting columns 5 are connected on the left and right sides of the guardrail 4, the connecting columns 5 are provided with a concave movable slot 6 in an array, the slot is inserted with an active hook 7, a reset spring 8 is connected between the active hook 7 and the movable slot 6, the active hook 7 includes a sloped hook 71 on the left side, a limited baffle 72 is provided on the right side of the hook 71, a pressing block 73 is connected to the right side of the limited baffle 72, and the spacing between the active hook 7 and the movable slot 6 is greater than the height of the hook 71.
[0024] When in use, first connect a column 1 with bolts, then insert the connecting column 5 at one end of the guardrail 4 into the socket 3. During the insertion process, the socket 3 will squeeze the slope of the hook 71, and a lateral force will be formed to convert into a tangential force, thereby squeezing the active hook 7 to slide inside the active slot 6. After insertion, the reset spring 8 pushes the active hook 7 to reset, and the limit baffle 72 will limit the rebound position to prevent the position from exceeding the setting. The pressing block 73 and the hook 71 will clamp the outer wall of the main column 1 to prevent shaking and falling off. The other end can be installed in the same way. When disassembly is required, just press the pressing block 73, press the squeezing hook 71 down, and then take it out.
[0025] like Figure 1-4 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, the angle of the hook 71 is ten to fifteen degrees, the height of the pressing block 73 is higher than the height of the hook 71, and the width of the pressing block 73 is the same as the column 1.
[0026] Analysis of the above structure shows that the angle of the hook 71 is 10 to 15 degrees. The smaller the angle, the easier it is to form a tangential force to push the hook 71 into the movable slot 6. When disassembling or adjusting, the height of the pressing block 73 is higher than the height of the hook 71, so the hook 71 can be pressed down more easily, thereby separating the socket 3 from the connecting column 5 and preventing the insertion from being too deep. The width of the pressing block 73 is the same as that of the column 1. After the connecting column 5 is inserted into the socket 3, the movable hook 7 is reset, and the pressing block 73 and the hook 71 will clamp the column 1 to reduce shaking.
[0027] like Figure 1-4 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, one end of the connecting column 5 is chamfered, and the outer side of the socket 3 is also chamfered.
[0028] From the analysis of the above structure, it can be seen that the chamfer at one end of the connecting column 5 and the chamfer at the outer side of the socket 3 can play a guiding role, making it easier for the connecting column 5 to be inserted into the socket 3.
[0029] like Figure 1-2 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, a plastic protective sleeve is provided around the inner side of the socket 3.
[0030] From the analysis of the above structure, it can be known that when the connecting column 5 is inserted into the inside of the socket 3, the plastic protective cover can prevent the metal friction between the connecting column 5 and the socket 3, and prevent the waterproof paint on the outside of the connecting column 5 from falling off.
[0031] like Figure 1-2 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, reflective stickers are attached to the front and rear surfaces of the guardrail 4.
[0032] From the analysis of the above structure, it can be known that when the light from the headlights or the like shines on the reflective sticker, the reflective sticker will reflect the light to remind the driver of the position of the guardrail 4 .
[0033] like Figure 1-4 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, the guardrail 4 includes a guardrail body 41, and the left and right sides of the guardrail body 41 are connected with rotating brackets 42 in an array shape. The left and right sides of the guardrail body 41 are provided with rotating rods 43, and the rotating rods 43 are connected with rotating brackets 2 44 near the guardrail body 41, and the rotating brackets 2 44 are connected to the rotating brackets 42 by bolts.
[0034] From the analysis of the above structure, it can be known that during installation, if there is a change in the angle, it is only necessary to slightly loosen the nuts on the upper ends of the internal bolts of the rotating bracket 42 and the rotating bracket 2 44, adjust the rotating rod 43 to the desired angle, and then tighten the bolts to adjust the angle.
[0035] like Figure 1-2 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, a solar warning light 21 is installed inside the upper end of the top cover 2, the solar panel of the solar warning light 21 is located at the upper end, and a light sensor is installed inside the solar warning light 21. The light sensor detection port is located on the outside of the solar warning light 21.
[0036] Analysis of the above structure shows that during the day, the light sensor turns off the solar warning light 21, and the solar panel generates electricity and stores energy. At night, the light sensor sends an electrical signal back to the solar warning light 21, and the solar warning light 21 lights up to remind the driver of the location of the guardrail.
