Description

Technical Field

[0001] The utility model relates to the technical field of disassembly and assembly of prefabricated guardrails, in particular to a prefabricated guardrail that can be quickly disassembled and assembled. Background Art

[0002] With the increasing busyness of road traffic, road guardrails, as important facilities to ensure driving safety, have become increasingly prominent in importance. Road guardrails can not only effectively limit the traveling range of vehicles and pedestrians and prevent them from rushing out of the road, but also absorb collision energy when the vehicle is out of control and reduce accident losses. In some cases, when road administration needs to construct a road, temporary guardrails will be used for protection. Among them, temporary guardrails can effectively isolate the traffic flow and the flow of people and ensure the safety of pedestrians and vehicles. Secondly, temporary guardrails have good mobility and flexibility and can be erected and removed at any time according to the needs of road construction or maintenance. In addition, urban temporary guardrails also have high durability and stability and can withstand the tests of bad weather and man-made damage.

[0003] In the prior art, when installing a temporary guardrail, generally the blocking part in the center is connected to the columns at both ends, and then it is placed at an appropriate position on the road through the base for use. However, when installing the center blocking part, generally the center blocking part is installed on the columns on both sides through bolts. And in some cases, the length of the temporary guardrail to be placed is relatively long. Therefore, it takes a lot of time to assemble the temporary guardrail, which reduces the installation efficiency and is likely to affect the traffic problems on the road. Summary of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a prefabricated guardrail that can be quickly disassembled and assembled, so as to solve the technical problems mentioned in the above background art.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] A prefabricated guardrail that can be quickly disassembled and assembled, including two bases, a first column and a second column. The first column and the second column are respectively arranged on the top sides of the two bases. Rectangular grooves are respectively opened on the opposite sides of the first column and the second column. A first insert block and a second insert block are respectively fixedly connected in the two rectangular grooves. A center railing is arranged between the first column and the second column. Through grooves corresponding to the first insert block and the second insert block are opened at the ends of the center railing. Secondary railings are connected to the upper and lower sides of the center railing through driving members. Limiting members are arranged on the top sides of the first column and the second column.

[0007] In a preferred embodiment, the present utility model can be further configured as follows: The driving member includes two driving gears, which are respectively rotatably installed on the upper and lower sides inside one end of the central railing close to the first upright post. Two racks are slidably connected to both sides inside the central railing, and the two racks are respectively engaged with the two driving gears. The end portions of the two racks are respectively fixedly connected to the two auxiliary railings.

[0008] In a preferred embodiment, the present utility model can be further configured as follows: Tooth grooves engaged with the driving gears are respectively formed on the upper and lower sides of the first plug block, and avoidance grooves for avoiding the two racks are respectively formed at the end portions of the first plug block.

[0009] In a preferred embodiment, the present utility model can be further configured as follows: The limiting member includes two vertical holes, which are respectively formed at the tops of the first upright post and the second upright post, and the two vertical holes are respectively communicated with the corresponding rectangular grooves.

[0010] In a preferred embodiment, the present utility model can be further configured as follows: Vertical rods are slidably connected inside the vertical holes, and limiting holes corresponding to the vertical rods are respectively formed at both ends of the auxiliary railing located on the top side of the central railing.

[0011] In a preferred embodiment, the present utility model can be further configured as follows: Clamping rods are respectively fixedly connected to the bottom ends of the first upright post and the second upright post, clamping grooves are respectively formed at the tops of the two bases, and the bottom ends of the first upright post and the second upright post are respectively clamped with the corresponding clamping grooves through the two clamping rods.

[0012] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0013] 1. For this quickly disassemblable and assembled guardrail, when in use, after sleeving the central railing on the second plug block, directly push the second upright post, so that the second upright post drives the central railing to sleeve on the first plug block and unfold the auxiliary railing. Finally, the corresponding auxiliary railing is positioned by the vertical rod. When disassembling, directly pull out the vertical rod and pull the first upright post and the second upright post outward, so as to quickly reset the central railing and the auxiliary railing, and finally separate the central railing from the first upright post and the second upright post, thus achieving the effects of quick installation and disassembly.

[0014] 2. For this quickly disassemblable and assembled guardrail, when the central railing covers the first plug block, at this time the driving gear rotates, which will drive the corresponding rack to rotate, and then drive the two auxiliary railings to move upward and downward respectively. After the central railing completely covers the first plug block through the through groove, at this time the auxiliary railings located on the upper and lower sides of the central railing will respectively fit with the upper and lower ends of the rectangular groove, and then are limited by the limiting member to achieve the effect of quick installation.

[0015] 3. When the central railing sleeve moves towards the first insertion block, the driving gear will pass through the tooth groove, and then drive the rotation of the driving gear through the tooth groove. The rotation of the driving gear will drive the corresponding rack to move, and finally press the two secondary railings against the upper and lower ends of the rectangular groove respectively, so as to achieve the effect of installing and unfolding the guardrail.

[0016] 4. When the corresponding secondary railing fits with the upper and lower ends in the rectangular groove respectively, the limiting hole will be aligned with the vertical hole, and then the vertical rod will be pushed downward. When the vertical rod is pushed downward, it will gradually pass through the vertical hole and insert into the limiting hole, so as to achieve the effect of limiting the secondary railing on the top side of the central railing, and avoid the central railing falling off when the first column and the second column are pulled to both sides.

The first upright post 2 and the second upright post 3 are respectively arranged on the top sides of the two bases 1. Rectangular grooves 4 are respectively formed on the opposite sides of the first upright post 2 and the second upright post 3. A first insert block 5 and a second insert block 6 are respectively fixedly connected in the two rectangular grooves 4. A central railing 7 is arranged between the first upright post 2 and the second upright post 3. Through grooves 20 corresponding to the first insert block 5 and the second insert block 6 are formed at the ends of the central railing 7. Secondary railings 9 are connected to the upper and lower sides of the central railing 7 through driving members 8 respectively. Limit members 10 are arranged on the top sides of the first upright post 2 and the second upright post 3.

[0025] In this embodiment, when in use, place the base 1 in a suitable position. Then, put the through groove 20 on the central railing 7 over the second insert block 6, align the through groove 20 with the first insert block 5, and then push the second upright post 3, so that the second upright post 3 drives the central railing 7 to cover the first insert block 5. During the process that the central railing 7 covers the first insert block 5 through the through groove 20, the two secondary railings 9 will be driven by the arranged driving members 8 to move upward and downward. After the central railing 7 completely covers the first insert block 5 through the through groove 20, at this time, the secondary railings 9 located on the upper and lower sides of the central railing 7 will respectively fit the upper and lower ends of the rectangular groove 4. Then, limit the secondary railing 9 located on the top side of the central railing 7 through the limit member 10, so as to achieve the effect of limiting the driving member 8, and finally complete the installation of the prefabricated guardrail.

[0026] In a further preferred embodiment of the utility model, as Figures 1 - 3 shown, the driving member 8 includes two driving gears 11.

A vertical rod 16 is slidably connected in the vertical holes 15, and limiting holes 17 corresponding to the vertical rod 16 are respectively formed at both ends of the secondary railing 9 located on the top side of the central railing 7.

[0031] In this embodiment, after the corresponding secondary railing 9 is respectively attached to the upper and lower ends in the rectangular groove 4, the limiting holes 17 will be aligned with the vertical holes 15, and then the vertical rod 16 is pushed downward. When the vertical rod 16 is pushed downward, it will gradually insert into the limiting holes 17 through the vertical holes 15, so as to achieve the effect of limiting the secondary railing 9 located on the top side of the central railing 7 and prevent the central railing 7 from falling off when the first upright post 2 and the second upright post 3 are pulled to both sides.

[0032] In a further preferred embodiment of the present utility model, as Figures 1 - 3 shown, clamping rods 18 are respectively fixedly connected to the bottoms of the first upright post 2 and the second upright post 3, and clamping grooves 19 are respectively formed at the tops of the two bases 1. The bottoms of the first upright post 2 and the second upright post 3 are respectively clamped with the corresponding clamping grooves 19 through the two clamping rods 18.

[0033] In this embodiment, after the secondary railing 9 on the central railing 7 is unfolded and the central railing 7 is fixed by the driving member 8 and the limiting member 10, at this time, the corresponding base 1 is placed at a suitable position, and then the clamping rods 18 at the bottoms of the first upright post 2 and the second upright post 3 are inserted into the corresponding clamping grooves 19, so as to achieve the purpose of fixing the guardrail.
