Embodiment 1

[0027] Example 1: See Figure 1-5 A kind of warning column that can be retracted by pressing the wheel, it includes a warning column body 1, an installation structure 2 and a pulling structure 3, a groove 4 is arranged on the ground, the installation structure 2 and the pulling structure 3 are installed in the groove 4, and the installation There is a sliding through hole 21 at the center of the structure 2, and the installation structure 2 can slide up and down in the sliding through hole 21. A plurality of support blocks 22 are uniformly arranged on the wall of the sliding through hole 21, and each support block 22 and the warning column body 1 Both are connected with a first spring 23, a connecting rope 5 is connected between the warning column body 1 and the pulling structure 3, the connecting rope 5 has no elasticity, and the pulling structure 3 pulls the connecting rope 5 so that the lower part of the warning column body 1 enters the sliding through hole 21, the overall ...

Embodiment 2

[0037] Embodiment 2: Different from Embodiment 1, the pulling structure 3 includes an annular pressing block 311, a plurality of evenly distributed pressing rods 312, and a plurality of evenly distributed rotating rods 32, and the inner wall of the groove 4 is also set and rotated The number of rods 32 is the same as that of the fixed blocks connected by rotation. The ends of the plurality of rotating rods 32 away from the fixed blocks are all connected to the connecting rope 5. When the tire acts on the ring-shaped pressing fast 311, it can pull the first sliding body 11 more stably and quickly. , so that the height of the warning column body 1 is lowered rapidly.

Embodiment 3

[0038] Embodiment 3: The difference from Embodiment 1 is that a layer of rubber is provided on the upper end of the annular pressing block 311 to ensure the life of the annular pressing block 311 .

Abstract

The invention belongs to the technical field of warning columns and discloses a warning column capable of stretching and retracting under the pressing of a wheel. The warning column comprises a warning column body, a mounting structure and a pulling structure; a groove is formed in the ground; the mounting structure and the pulling structure are both mounted in the groove; a sliding through hole is formed in the center of the mounting structure; the mounting structure can slide up and down in the sliding through hole; a plurality of supporting blocks are evenly arranged on the hole wall of the sliding through hole; each supporting block and the warning column body are connected with a first spring; a connecting rope is connected between the warning column body and the pulling structure; the connecting rope is not elastic; and the pulling structure pulls the connecting rope so that the lower portion of the warning column body can enter the sliding through hole, the overall height of the warning column body is decreased, after external force acts on the warning column body with the decreased height, the warning column body completely enters the sliding through hole, and the service life of the warning column is greatly prolonged.

Description

technical field [0001] The invention relates to the field of warning posts, in particular to a warning post that can be retracted by pressing a wheel. Background technique [0002] The warning poles are mainly placed at urban intersections and sidewalks, etc., as a separation and warning function. During the day, the red, white, red and yellow colors are eye-catching and obvious. At night, the reflective strips can reflect dazzling light to remind drivers to pay attention and achieve the purpose of guiding traffic. . [0003] The warning posts set on the ground at the existing intersections are all made of rubber, which are elastic and have a cavity inside, and the posts will not expand and contract. If it is crushed for a long time, the warning column will break and its life will be short. Contents of the invention [0004] The invention provides a warning column that can be retracted by pressing the wheel, which can solve the above-mentioned technical problems. [000...
