Description

Technical Field

[0001] This utility model relates to the field of traffic guardrails, and in particular to a foldable temporary traffic guidance guardrail. Background Technology

[0002] Traffic barriers are traffic safety facilities installed on both sides or in the central divider of a road. They are mainly used to prevent vehicles from losing control and running off the road or crossing into the opposite lane, thus ensuring the safety of pedestrians and vehicles.

[0003] When carrying out road repair work, it is generally necessary to add temporary guardrail structures to divide the entire road, creating a narrow path that can be passed through without affecting the road repair work. Folding guardrails are a commonly used device for road division. They can be extended and folded, making them easy to carry. A section of the guardrail can be extended to a sufficient length for use, so its use is quite widespread.

[0004] However, the following defects and shortcomings still exist in the application implementation process:

[0005] Traditional guardrails extend and retract along a straight line and cannot be bent or adjusted. Therefore, when the road section being repaired (the edge of the excavated area) is a curved arc structure, it cannot be bent or adjusted according to the actual site conditions.

[0006] Therefore, it is necessary to provide a new type of foldable temporary traffic guidance barrier to solve the above-mentioned technical problems. Utility Model Content

[0008] The foldable temporary traffic guidance guardrail provided by this utility model includes two symmetrically arranged posts, and a scissor-type telescopic guardrail between the two posts.

[0009] The scissor-type telescopic fence includes a first folding arm and a second folding arm.

[0010] The second folding arms on the two columns are close to each other and connected by an auxiliary connector, which allows the second folding arms to rotate horizontally.

[0011] Preferably, a vertical rod is welded and fixed to the column near the bottom, and multiple counterweights are fitted onto the vertical rod.

[0012] Preferably, there are two first folding arms and two second folding arms. The length of the first folding arm is twice the length of the second folding arm. The two first folding arms are arranged crosswise and connected by a shaft. One end of the first folding arm is connected to the column and the other end is connected to the second folding arm.

[0013] Preferably, the auxiliary connector includes a first connecting seat and a second connecting seat, the first connecting seat and the second connecting seat being rotatably connected to the second folding arms on the two columns respectively;

[0014] A first positioning seat is welded and fixed on one side of the first connecting seat, and a vertically arranged rotating shaft is welded and fixed on the first positioning seat. Two second positioning seats distributed vertically are welded and fixed on one side of the second connecting seat. The rotating shaft passes through the second positioning seats and is rotatably connected to them.

[0015] Preferably, the lower end face of the second positioning seat located in the upper position is fixed with a first tooth distributed in a ring.

[0016] Preferably, the upper end of the rotating shaft has an axially arranged sliding cavity, and multiple axially arranged slides communicating with the sliding cavity are formed on the outer circumferential wall of the rotating shaft. A pressure rod is slidably connected inside the sliding cavity. The upper end of the pressure rod extends above the rotating shaft. Multiple connecting plates are welded and fixed to the outer circumferential wall of the pressure rod. The connecting plates extend along the slides to the outside of the rotating shaft and are fixed with a slip ring sleeved on the outside of the rotating shaft.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 5The present invention provides a foldable temporary traffic guidance guardrail, which includes two symmetrically arranged posts 1 and a scissor-type telescopic guardrail 2 between the two posts 1.

[0032] The scissor-type telescopic guardrail 2 includes a first folding arm 21 and a second folding arm 22;

[0033] The second folding arms 22 on the two columns 1 are close to each other and connected by an auxiliary connector 3, which allows the second folding arms 22 to rotate horizontally.

[0034] It should be noted that in this device, the upright post 1, the scissor-type telescopic guardrail 2, and the auxiliary connector 3 form a complete guardrail structure. The auxiliary connector 3 is located in the middle of the entire guardrail structure and can rotate to allow the entire guardrail structure to bend and adjust from the middle position, thereby making targeted adjustments according to the actual bending changes of the repair area and increasing its applicability.

[0035] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 A vertical rod 11 is welded and fixed to the column 1 near the bottom, and multiple counterweights 12 are fitted on the vertical rod 11.

[0036] It should be noted that the counterweight 12 is mainly used to increase the stability of the entire device. In particular, a few counterweights 12 can be added in windy weather, while they can be omitted in windless environments.

[0037] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 There are two first folding arms 21 and two second folding arms 22. The length of the first folding arm 21 is twice the length of the second folding arm 22. The two first folding arms 21 are arranged crosswise and connected by a shaft. One end of the first folding arm 21 is connected to the column 1 and the other end is connected to the second folding arm 22.

[0038] It should be noted that the first folding arm 21 is connected to the column 1, and the length of the second folding arm 22 is half the length of the first folding arm 21. One end of the second folding arm 22 is connected to the first folding arm 21. Therefore, when arranging the column 1, the two columns 1 are pulled apart directly. At this time, the first folding arm 21 starts to rotate and extend, which in turn drives the second folding arm 22 to rotate and extend together.

[0039] In the embodiments of this utility model, please refer to Figure 3 The auxiliary connector 3 includes a first connecting seat 31 and a second connecting seat 34, which are rotatably connected to the second folding arms 22 on the two columns 1 respectively.

[0040] A first positioning seat 32 is welded and fixed on one side of the first connecting seat 31. A vertically arranged rotating shaft 33 is welded and fixed on the first positioning seat 32. Two second positioning seats 35 distributed vertically are welded and fixed on one side of the second connecting seat 34. The rotating shaft 33 passes through the second positioning seats 35 and is rotatably connected to them.

[0041] It should be noted that the other end of the second folding arm 22 is connected to the connecting seat, and the first connecting seat 31 and the second connecting seat 34 are connected by a pivot 33 to connect the second folding arm 22 in the two columns 1. At the same time, it can also play a certain limiting role for the second folding arm 22 to cooperate with the first folding arm 21 to extend and retract.

[0042] In the embodiments of this utility model, please refer to Figures 3 to 5 The lower end face of the second positioning seat 35 located at the upper position is fixed with the first teeth 36 distributed in a ring.

[0043] Meanwhile, the upper end of the rotating shaft 33 has an axially arranged sliding cavity 37. Multiple axially arranged slides 38 are provided on the outer circumferential wall of the rotating shaft 33 and are connected to the sliding cavity 37. A pressure rod 39 is slidably connected inside the sliding cavity 37. The upper end of the pressure rod 39 extends to the top of the rotating shaft 33. Multiple connecting plates 310 are welded and fixed to the outer circumferential wall of the pressure rod 39. The connecting plates 310 extend along the slides 38 to the outside of the rotating shaft 33 and are fixed with a slip ring 311 sleeved on the outside of the rotating shaft 33. The upper end face of the slip ring 311 is provided with a second tooth 312 that can mesh with the first tooth 36.

[0044] A spring 313 is also fitted on the rotating shaft 33. One end of the spring 313 abuts against the first positioning seat 32, and the other end abuts against the slip ring 311, so that the slip ring 311 moves up to the highest position.

[0045] It should be noted that: Under normal conditions, when the spring force of the spring 313 is applied, the slip ring 311 moves up to the highest position. In this state, the first tooth 36 and the second tooth 312 mesh together, which can limit the rotation between the two connecting seats and keep them stable. Therefore, the stability is higher after the guardrail is installed.

[0046] When adjustment is needed, press down the pressure rod 39, which drives the slip ring 311 to move, causing the second tooth 312 to disengage from the first tooth 36, thus allowing the two sets of connecting seats to be rotated and adjusted.

[0047] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0048] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
