Description

Technical Field

[0001] This utility model belongs to the field of guardrails, and in particular relates to a temporary guardrail for urban roads. Background Technology

[0002] Guardrails are important safety facilities in urban transportation systems, combining functionality and aesthetics. They are primarily used to separate traffic flows, ensure driving safety, and improve the urban environment. Through physical separation, guardrails clearly delineate motor vehicle lanes, non-motor vehicle lanes, and pedestrian walkways, reducing the risks of vehicles changing lanes or making U-turns at will, or pedestrians crossing the road haphazardly, while also providing a certain degree of buffering capacity.

[0003] Existing guardrails are usually fixed structures, installed on the road surface with expansion bolts. However, with urban development and construction, there are often road construction and detours in cities. Fixed guardrails are cumbersome to install and dismantle, inconvenient to use, and have poor flexibility, which may affect the efficiency of road construction and thus affect road traffic. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a temporary guardrail for urban roads, aiming to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows: a temporary guardrail for urban roads includes:

[0006] Column body, including

[0007] Multiple crossbeams, wherein each crossbeam is movably hinged to an adjacent crossbeam via a connector welded to its end;

[0008] Multiple crossbeams 2 are arranged parallel to crossbeam 1. Each crossbeam 2 has a connector movably installed at its end via a fixed unit. Each crossbeam 2 is movably hinged to an adjacent crossbeam 2 via the connector movably installed at its end.

[0009] Vertical rods are installed vertically and connect the sides of crossbeam one and crossbeam two.

[0010] Two columns, each with multiple mounting heads fixedly installed on its side, the mounting heads being fixedly connected to the ends of crossbeam one and crossbeam two via pins;

[0011] The base is placed on the ground to support and fix the column.

[0012] As a further embodiment of this utility model: the connector includes two symmetrically arranged female heads, which are movably hinged together by insert plates. The two ends of the insert plates are respectively hinged to the female heads by movable shafts. One end of each female head is fixedly provided with a plug for engaging with crossbeam one and crossbeam two.

[0013] As a further aspect of this utility model: the fixing unit includes:

[0014] Fixed bolts, movable through the two side walls of the crossbeam and the connector;

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.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figure 1 and Figure 6 This utility model embodiment provides a temporary guardrail for urban roads, comprising:

[0034] Section 1, including

[0035] Multiple crossbeams 11, wherein the crossbeams 11 are movably hinged to adjacent crossbeams 11 via connectors 13 welded to their ends;

[0036] Multiple crossbeams 12 are arranged parallel to crossbeam 11. Each crossbeam 12 has a connector 13 movably mounted at its end via a fixing unit 14. The crossbeam 12 is movably hinged to the adjacent crossbeam 12 via the connector 13 movably mounted at its end.

[0037] Vertical rod 15 is vertically installed and connects the sides of crossbeam one 11 and crossbeam two 12;

[0038] Two columns 2, each with multiple mounting heads 23 fixedly installed on its side, the mounting heads 23 being fixedly connected to the ends of crossbeam 11 and crossbeam 22 via pins 231;

[0039] The base 3 is placed on the ground to support and fix the column 2.

[0040] In practical application, the first crossbeam 11 and the second crossbeam 12 are folded and unfolded by the connector 13, and then the first crossbeam 11 and the second crossbeam 12 are snapped and fixed on the mounting head 23 by the pin 231, so as to connect and fix the fence body 1 and the post 2. Then the post 2 is fixedly installed on the base 3 to realize the assembly of the temporary guardrail.

[0041] In this embodiment, the connecting head 13 is hinged with the first crossbeam 11 and the second crossbeam 12 to form a folding structure, which can realize the folding of the first crossbeam 11 and the second crossbeam 12. This makes it convenient for the guardrail to be folded and unfolded when in use and folded and stored when not in use. At the same time, its folding structure gives the guardrail a certain degree of deformation capability to adapt to different usage scenarios and has greater flexibility.

[0042] Please see Figure 2 and Figure 5 In another preferred embodiment of the present invention, the connector 13 includes two symmetrically arranged female heads 131. The two female heads 131 are movably hinged by a insert plate 132. The two ends of the insert plate 132 are respectively hinged and installed in the female head 131 by a movable shaft 133. One end of the female head 131 is fixedly provided with a plug 1311 for engaging with the first crossbeam 11 and the second crossbeam 12.

[0043] In practical application, this embodiment uses two symmetrically arranged female heads 131 and a plug 1311 at the end of the female head 131 to engage with the first crossbeam 11 or the second crossbeam 12. The insert plate 132 is hinged and installed in the female head 131 in conjunction with the movable shaft 133, so that the female head 131 and the insert plate 132 can rotate around the movable shaft 133 to form a folding mechanism, thereby realizing the folding of the first crossbeam 11 and the second crossbeam 12.

[0044] Please see Figure 5 In another preferred embodiment of this utility model, the fixing unit 14 includes:

[0045] Fixed bolt 141, movable through-beam 2 12 side wall and plug 1311;

[0046] The fixing nut 142 is threadedly engaged with the fixing bolt 141 and fixedly installed at the end of the fixing bolt 141;

[0047] Washer 143 is mounted on fixing nut 142 and located on both sides of crossbeam 12.

[0048] Furthermore, two symmetrical limiting grooves 121 are fixedly opened at the position of the fixing bolt 141 on the second crossbeam 12. The fixing bolt 141 can rotate in the limiting groove 121. A spring 144 for assisting compression and limiting is also movably installed between the fixing nut 142 and the washer 143.

[0049] In practical application, this embodiment uses a fixing unit 14 that passes through the second crossbeam 12 and the connector 1311 to connect and fix the second crossbeam 12 and the connector 13. The limiting groove 121 allows the connector 13, together with the fixing unit 14, to rotate around the second crossbeam 12, thereby changing the angle of the connector 13 installed on the second crossbeam 12. This creates a certain angle difference between the connector 13 installed on the second crossbeam 12 and the connector 13 installed on the first crossbeam 11, thus fixing the railing 1 due to the change in its folding direction and preventing deformation after unfolding.

[0050] Please see Figure 2 and Figure 3 In another preferred embodiment of this utility model, the column 2 includes an outer column 21, which is fixedly mounted on the base 3. An insert post 22 is movably inserted into the outer column 21. Multiple adjustment holes 211 are fixedly opened at equal intervals on the side of the outer column 21. An movable groove 221 is fixedly opened on the insert post 22. A movable head 222 is movably installed in the movable groove 221. The movable head 222 is squeezed and mounted in the adjustment hole 211 by a spring 223 movably installed in the movable groove 221.

[0051] Furthermore, the vertical rod 15 includes an outer rod 151 and an insert rod 152. The outer rod 151 is fixedly installed on the first crossbeam 11, and the insert rod 152 is fixedly installed on the second crossbeam 12. The outer rod 151 and the insert rod 152 are movably connected.

[0052] In practical application, this embodiment uses the adjustment hole 211 in conjunction with the spring 223 and the movable head 222 to allow the overall height of the column 2 to be adjusted by the extension and retraction of the outer column 21 and the insert column 22. In conjunction with the movable insertion of the outer rod 151 and the insert rod 152, the height of the fence 1 can be adjusted, thereby adjusting the overall height of the guardrail and further improving the flexibility of the guardrail.
