[0032] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] An embodiment of the present invention discloses a warning sign for road construction.

[0034] The present invention provides a warning sign for road construction as shown in Figure 1-8 Figure 1, which includes a main rod 1, an inner rod 2 telescopically installed in the inner cavity of the main rod 1, and a warning sign body 3 installed at the top of the inner rod 2. A moving ring 4 is slidably sleeved on the outer wall of the main rod 1, and a fixed ring 5 is integrally formed and connected to the bottom end of the main rod 1. A plurality of connecting pieces 6 are connected to the outer wall of the moving ring 4. The inner side of the connecting piece 6 is rotatably connected to a support rod 7. Both sides of the middle of the support rod 7 are rotatably connected to a link rod 8 through a rotating shaft, and the end of the link rod 8 away from the support rod 7 is rotatably connected to the outer wall of the fixed ring 5 through a rotating shaft.

[0035] Three connecting pieces 6 are evenly distributed in a circular array, and the connecting piece 6 is integrally in an "n" shape. A stable bottom pad 9 is provided at the end of the support rod 7 away from the connecting piece 6. If the stable bottom pad 9 is made of a hard material, it can be directly welded to the bottom end of the support rod 7. If the stable bottom pad 9 is made of a flexible material, it can be adhered to the bottom end of the support rod 7.

[0036] A driving ring 10 is provided between the moving ring 4 and the fixed ring 5, and handles 11 are fixedly installed on the outer walls of the moving ring 4 and the driving ring 10. The handles 11 are used to push the moving ring 4, the connecting piece 6, and the driving ring 10 as a whole to move vertically upward or downward.

[0037] When it is necessary to deploy the support rod 7, only need to push the handle 11 downward so that the link rod 8 moves downward along with the driving ring 10, and the link rod 8 rotates to deploy the support rod 7. The stable bottom pads 9 at the bottoms of the three support rods 7 are in contact with the ground, realizing the support for the warning sign body 3 at the top; when it is necessary to retract the support rod 7, only need to push the handle 11 upward to retract the support rod 7, realizing the convenient deployment and retraction of the support rod 7. And because the handle 11 is provided on the moving ring 4, during the deployment or retraction of the support rod 7, the phenomenon that the support rod 7 pinches the hand can be effectively avoided, the operation is simple, and it is convenient to carry, move or store the warning sign.

[0038] To improve the practicality of the device, as Figure 4-5 shown, an adjustment assembly is installed between the main rod 1 and the inner rod 2. The adjustment assembly includes a connection block 12 integrally formed and connected to the outer wall of the top end of the main rod 1, an adjustment screw 13 threadedly connected to the connection block 12, a knob 14 welded to the end of the adjustment screw 13 away from the inner rod 2, an arc-shaped clamping member 15 rotatably connected to the end of the adjustment screw 13 close to the inner rod 2, and an anti-slip pad 16 adhered to the inner side of the arc-shaped clamping member 15.

[0039] After the support rod 7 is unfolded, according to the specific situation and the height requirement for placing the warning sign body 3, pull up the inner rod 2 in the inner cavity of the main rod 1. When the length of the inner rod 2 is adjusted, rotate the knob 14 to drive the adjustment screw 13 to approach the inner rod 2, so that the adjustment screw 13 drives the arc-shaped clamping member 15 to move horizontally, and clamp the outer wall of the inner rod 2 through the anti-slip pad 16, increasing the friction between the arc-shaped clamping member 15 and the inner rod 2, thereby realizing the fixation of the overall height position of the inner rod 2.

[0040] And to improve the stability of the device, as Figure 6 shown, a U-shaped block 17 for supporting the warning sign body 3 is fixedly installed at the top end of the inner rod 2. Locking rods 18 are symmetrically arranged on the U-shaped block 17, and the locking rods 18 movably penetrate through the wall of the U-shaped block 17. One ends of the two locking rods 18 away from the warning sign body 3 are connected through a pull plate 19.

[0041] A reset member 20 is connected between the outer wall of the pull plate 19 and the outer wall of the U-shaped block 17, and the reset member 20 is sleeved outside the locking rod 18. The reset member 20 is not specifically limited. To conform to the actual situation, the reset member 20 can be a spring; locking holes 21 corresponding to the number of the locking rods 18 are formed on the wall of the warning sign body 3, and the warning sign body 3 is fixed on the U-shaped block 17 by inserting one end of the locking rod 18 into the locking hole 21.

[0042] When the inner rod 2 has been retracted into the inner side of the main rod 1, the support rod 7 is folded, and it is necessary to remove the warning sign body 3 for storage, pull the pull plate 19 outward, and stretch the reset member 20, so that the locking rod 18 is disengaged from the locking hole 21 on the wall of the warning sign body 3, thereby releasing the fixation of the warning sign body 3, and then the warning sign body 3 can be removed. Subsequently, under the elastic action of the reset member 20, the pull plate 19 drives the two locking rods 18 to reset synchronously.

[0043] Finally, to improve the functionality of the device, as Figure 1 、 Figure 7 and Figure 8As shown, a plug rod 22 is slidably connected to the bottom of the main rod 1. The bottom end of the plug rod 22 is in an inverted conical shape. A C-shaped groove 23 is formed inside the main rod 1. A short column 24 is fixedly installed on the outer wall of the plug rod 22, and the short column 24 is slidably connected to the C-shaped groove 23. A cavity is formed inside the plug rod 22, and the inner diameter of the cavity is the same as the outer diameter of the inner rod 2. When storing the device, the inner rod 2 can be completely retracted into the cavity of the plug rod 22, without affecting the contraction position between the inner rod 2 and the plug rod 22.

[0044] When the short column 24 is located at the bottom end of the C-shaped groove 23, the plug rod 22 is in an extended state; when the short column 24 is located at the top end of the C-shaped groove 23, the plug rod 22 is in a contracted state.

[0045] Due to the actual influence of construction weather or terrain, in order to prevent the warning sign body 3 from collapsing, it is necessary to further fix the overall position of the main rod 1. At this time, just hold the outer wall of the plug rod 22 and rotate it to one side, then vertically pull it downwards, and then rotate it to the other side, so that the short column 24 moves from the top end of the C-shaped groove 23 to the bottom end of the C-shaped groove 23, fixing the plug rod 22 at the extended position, and then inserting it into the sand or soil, realizing that the overall position of the main rod 1 can be consolidated according to the actual situation; when the plug rod 22 is not needed, move the short column 24 from the bottom end of the C-shaped groove 23 to the top end of the C-shaped groove 23, so that the plug rod 22 retracts into the inside of the main rod 1.

[0046] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
