[0031] See also Figure 1-5 The utility model provides a technical solution: a quick-connect road guardrail that does not require installation, including a guardrail base 1 and a guardrail 2, a mounting assembly, the mounting assembly being arranged on the upper surface of the guardrail base 1, the mounting assembly including a fixing column 5, the interior of the fixing column 5 being hollow;

[0032] The front and rear surfaces of the fixing column 5 are both provided with sliding grooves 15 communicating therewith.

[0033] Furthermore, the mounting assembly further includes a threaded rod 14, which is rotatably connected to the inner wall of the fixed column 5. Two movable sleeves 13 are threadedly sleeved on the outer wall of the threaded rod 14. The front and rear surfaces of the two movable sleeves 13 are fixedly connected to rectangular blocks 10. The four rectangular blocks 10 all slide through two sliding grooves 15.

[0034] The ends of the two upper and lower corresponding rectangular blocks 10 away from the movable sleeve 13 are both fixedly connected to the mounting plate 3 .

[0035] Furthermore, T-shaped grooves 8 are provided on the opposing surfaces of the two mounting plates 3, and rectangular grooves 9 communicating with the two T-shaped grooves 8 are provided on the upper ends of the left and right sides of the two mounting plates 3, and the inner walls of the two corresponding rectangular grooves 9 on the left and right are slidably connected to the limiting plate 4.

[0036] Furthermore, fixing holes 16 are provided on both left and right sides of the upper surfaces of the two limiting plates 4 , and the four fixing holes 16 pass through the lower surfaces of the two limiting plates 4 .

[0037] Furthermore, the mounting assembly further includes a worm 12, which is fixedly sleeved on the outer wall of the threaded rod 14. A turbine 11 is provided on the rear side of the worm 12, and the turbine 11 is rotatably connected to the inner wall of the fixed column 5. The worm 12 and the turbine 11 are meshed with each other.

[0038] The left end of the worm 12 rotates and passes through the left side of the fixed column 5. The left end of the worm 12 is fixedly connected to the crank 6. There are multiple mounting components, and one mounting component can be quickly connected to two guardrails 2.

[0039] Furthermore, the front and rear surfaces of the guardrail 2 are fixedly connected with a T-shaped slider 7, and the T-shaped slider 7 is slidably connected to the inner wall of the T-shaped slide groove 8. The guardrail base 1 is made of plastic, and a counterweight block is provided inside the guardrail base 1. The length of the guardrail 2 can be determined according to actual conditions.

[0040] Furthermore, when using the present installation-free quick-connect road guardrail, first, multiple guardrail bases 1 and guardrails 2 are transported to a designated location by a transportation vehicle, then a guardrail base 1 is taken out as a whole, the guardrail base 1 is placed as a whole at a designated installation location, the guardrail 2 is taken out, the T-shaped slider 7 on the guardrail 2 is inserted into the interior of the T-shaped chute 8, and then another guardrail base 1 is taken out as a whole, and the other T-shaped slider 7 on the guardrail 2 is inserted into the interior of the T-shaped chute 8 on the new guardrail base 1 as a whole. Figure 1As shown), take out another guardrail 2 and repeat the above steps to complete the quick connection of the guardrail 2 as a whole. By setting the T-shaped slider 7 and the T-shaped slot 8, the quick connection of the guardrail 2 as a whole can be achieved. There is no need to use cumbersome methods such as fixed threads or welding to install the guardrail 2 as a whole, thereby improving the installation efficiency.

[0041] Furthermore, when it is necessary to adjust the upper and lower distances of the guardrail 2, the crank 6 drives the worm 12 to rotate, and the worm 12 drives the threaded rod 14 to rotate through the turbine 11. The threaded rod 14 drives the two mounting plates 3 to move up and down through the movable sleeve 13 and the four rectangular blocks 10, and the two mounting plates 3 thereby drive the guardrail 2 to move upward. The effect of adjusting the upper and lower positions of the guardrail 2 is achieved by rotating the worm 12 forward and reversely in coordination with the threaded rod 14, thereby improving the adaptability of the guardrail 2 to work in different environments.

[0042] Working principle: When using this installation-free quick-connect road guardrail, first transport multiple guardrail bases 1 and guardrails 2 to the designated location by means of transportation, then take out a guardrail base 1 as a whole, place the guardrail base 1 as a whole on the designated installation, take out the guardrail 2, insert the T-shaped slider 7 on the guardrail 2 into the inside of the T-shaped slide 8, then take out another guardrail base 1 as a whole, insert the other T-shaped slider 7 on the guardrail 2 into the inside of the T-shaped slide 8 on the new guardrail base 1 as a whole ( Figure 1 As shown), another guardrail 2 is taken out, and the above steps are repeated to complete the quick connection of the guardrail 2 as a whole. When the upper and lower distances of the guardrail 2 need to be adjusted, the crank 6 drives the worm 12 to rotate, and the worm 12 drives the threaded rod 14 to rotate through the turbine 11. The threaded rod 14 drives the two mounting plates 3 to move up and down through the movable sleeve 13 and the four rectangular blocks 10, and the two mounting plates 3 thereby drive the guardrail 2 to move upward.
