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.

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] A municipal highway bridge anti-collision guardrail assembly structure includes a guardrail body 1, and assembly columns 2 for assembling the guardrail body 1 are arranged on both sides of the guardrail body 1, a support plate 21 is fixedly installed on the surface of the assembly column 2, a fixing bolt 22 is perforated on the surface of the support plate 21, a mounting block 23 is fixedly connected to the top of the fixing bolt 22, a first nut 24 is threadedly connected on the surface of the fixing bolt 22, an installation bolt 25 is perforated on the surface of the installation block 23, the installation bolt 25 is threadedly connected to the guardrail body 1, and a connecting rod 26 is fixedly connected to the surface of the installation block 23. The assembly mechanism can adjust the assembly angle of the guardrail body 1 on the assembly column 2, thereby improving the flexibility of assembling the guardrail body 1 on the assembly column 2.

[0024] Furthermore, an adjustment mechanism is provided on the surface of the assembling column 2, and the adjustment mechanism includes a slider 3, which is slidably connected to the surface of the assembling column 2, and a connecting plate 31 is fixedly connected to the surface of the slider 3. A limiting screw 32 is perforated and connected on the surface of the assembling column 2, and a second nut 33 is threadedly connected on the surface of the limiting screw 32. The adjustment mechanism can adjust the height of the support plate 21 on the assembling column 2, thereby changing the assembly height of the guardrail body 1 on the assembling column 2, and can appropriately adjust the height of the support plate 21 according to the size of the guardrail body 1.

[0025] Furthermore, a circular hole is opened on the surface of the support plate 21, and the fixing bolt 22 is connected to the circular hole of the support plate 21 through the hole. The fixing bolt 22 can rotate on the circular hole of the support plate 21, and the mounting block 23 rotates on the surface of the support plate 21 through the fixing bolt 22, thereby realizing the rotation of the mounting block 23 on one side of the assembly column 2. The mounting block 23 changes the installation angle of the guardrail body 1 during the rotation process, thereby facilitating the appropriate adjustment of the installation angle of the assembly column 2 on the guardrail body 1, thereby improving the flexibility of installing the guardrail body 1 on the assembly column 2.

[0026] Furthermore, a mounting groove is provided on the surface of the mounting block 23, and the guardrail body 1 is snap-fitted to the mounting groove of the mounting block 23. A circular hole is provided on the surface of the mounting block 23, and a threaded hole is provided on the surface of the guardrail body 1. The mounting groove of the mounting block 23 is connected to the circular hole of the mounting block 23, and the mounting bolt 25 enters the mounting groove of the mounting block 23 through the circular hole of the mounting block 23. The mounting bolt 25 will be threadedly connected to the threaded hole of the guardrail body 1 on the mounting groove of the mounting block 23, so that the mounting bolt 25 restricts the guardrail body 1 to the mounting groove of the mounting block 23.

[0027] Furthermore, the first nut 24 is rotated at the bottom of the fixing bolt 22 so that the first nut 24 is abutted against the lower surface of the support plate 21, and the mounting block 23 can no longer rotate on the support plate 21. The mounting block 23 is fixedly mounted on the support plate 21 by the fixing bolt 22, and the guardrail body 1 is fixedly mounted on the mounting groove of the mounting block 23 by the mounting bolt 25. Two groups of mounting bolts 25 are provided on one side of the assembly column 2, and the connecting rod 26 is in a "U" shape. The mounting bolts 25 are fixedly connected to both ends of the connecting rod 26. The connecting rod 26 can limit the rotation angle of the two groups of mounting blocks 23 on one side of the assembly column 2, thereby reducing the number of rotations of the mounting block 23 and improving the convenience of assembling the guardrail body 1 on the assembly column 2.

[0028] Furthermore, two groups of guide holes are opened on the surface of the assembly column 2, the slider 3 and the connecting plate 31 are perpendicular to each other, the slider 3 slides in the guide holes of the assembly column 2, the connecting plate 31 slides on the surface of the assembly column 2 through the slider 3, the support plate 21 is fixedly connected to the surface of the connecting plate 31, and the connecting plate 31 drives the support plate 21 to rise and fall on the surface of the assembly column 2, and the slider 3 and the connecting plate 31 restrict each other, so that the slider 3 and the connecting plate 31 can only go straight up and down on the assembly column 2.

[0029] Furthermore, circular holes are opened on the surface of the assembly column 2, and the circular holes of the assembly column 2 are linearly and evenly arranged on the surface of the assembly column 2. A circular hole is opened on the surface of the slider 3. The limiting screw 32 penetrates the circular holes of the slider 3 and the assembly column 2 at the same time. The limiting screw 32 cooperates with the second nut 33 to fix the slider 3 on the guide hole of the assembly column 2. The slider 3 limits the position of the support plate 21 on the assembly column 2 through the connecting plate 31, thereby realizing the adjustment of the height of the support plate 21 on the assembly column 2.

[0030] Working principle: The fixing bolt 22 is perforated and connected to the circular hole of the support plate 21, and the mounting block 23 is rotated on the surface of the support plate 21 through the fixing bolt 22. The connecting rod 26 ensures that the angles of the mounting blocks 23 on the same side of the assembly column 2 are the same on the mounting block 23. After adjusting the angle of the mounting block 23, the first nut 24 is rotated on the fixing bolt 22, so that the first nut 24 fixes the mounting block 23 on the support plate 21 through the fixing bolt 22. At this time, the guardrail body 1 is snap-connected to the mounting groove of the mounting block 23, the mounting bolt 25 is passed through the circular hole of the mounting block 23, and the first nut 24 is threadedly connected to the threaded hole of the guardrail body 1, thereby completing the assembly of the guardrail body 1 on the assembly column 2.

[0031] The slider 3 is slid on the guide hole of the assembly column 2, and the slider 3 drives the connecting plate 31 to slide on the surface of the assembly column 2, and the connecting plate 31 drives the support plate 21 to rise and fall, thereby changing the installation position of the guardrail body 1 on the assembly column 2, and the limiting screw 32 passes through the circular holes of the assembly column 2 and the slider 3 at the same time, and the second nut 33 cooperates with the upper limit screw 32 to fix the slider 3 on the assembly column 2, and the slider 3 then limits the support plate 21 on the assembly column 2 through the connecting plate 31, thereby completing the adjustment of the height of the support plate 21, and then realizing the adjustment of the installation height on the assembly column 2.
