Technical Field
[0001] The utility model relates to the technical field of road isolation railings, and particularly relates to a base structure of a road isolation railing. Background Technique
[0002] With the acceleration of the urbanization process and the rapid increase in the number of motor vehicles, the problems existing in road conditions and traffic conditions are very prominent. Among them, the lack or failure of traffic auxiliary facilities and imperfect road alignment are the main causes of traffic accidents, which are mainly manifested as: pedestrians crossing the street at will, motor vehicles making U-turns and driving in reverse wantonly, and other illegal phenomena often occur; the brightness of the night lighting system is insufficient, and the driver obtains insufficient new visual information, which is likely to lead to misjudgment of direction and vehicle distance by the driver; the strong light emitted by the high beams of vehicles in the oncoming lane is extremely likely to induce glare; the change of the alignment at the curve is not easy to attract the attention of the driver, resulting in misjudgment and operation errors. Therefore, it is necessary to add isolation facilities on the road to improve the traffic and road surface environment;
[0003] The existing road isolation facilities mainly include isolation fences, central green belts and connecting guardrails. The most common in urban roads is to design an isolation fence with a height of about 1.2m in the middle of the road, which has a certain anti-falling ability, which can effectively prevent pedestrians from crossing the street at will, vehicles making U-turns wantonly, driving in the oncoming lane, etc., reduce the conflict between people and vehicles, and improve road traffic safety.
[0004] Most of the existing road isolation fences and bases are of a fixed connection structure. When impacted by external forces, only the deformation of the isolation fence can be relied on to relieve the impact, resulting in a large loss; therefore, we propose a base structure of a road isolation railing to solve the problems mentioned above. Content of the Utility Model

[0006] Technical Solution: A base structure of a road isolation railing, including a base, a guardrail column is arranged at the upper end of the base, and the lower end of the guardrail column extends into the interior of the base. Positioning plates are installed on the outer walls of the front end and the rear end of the base. Two first connectors are installed on the inner walls of the positioning plates. The end of the first connector is rotationally connected to a first spring seat. A shock-absorbing return spring is installed at the end of the first spring seat. A damping rod is installed inside the shock-absorbing return spring. One end of the shock-absorbing return spring is installed with a second spring seat. The end of the second spring seat is rotationally connected to a second connector, and the second connector is fixedly connected to the outer wall of the guardrail column.
[0007] Preferably, pin seats are installed on both sides above the base, pins are arranged on both sides of the guardrail column, and the guardrail column is rotatably connected to the pin seat through the pin.
[0008] Preferably, flexible rubber sealing layers are arranged at the joints of the front end and the rear end of the guardrail column and the base.
[0009] Preferably, a sponge cushion block is arranged at the lower end of the guardrail column, and the sponge cushion block is adhesively connected to the bottom surface of the base.
[0010] Preferably, the four corners of the positioning plate are connected to the base by screws.
[0011] Preferably, grounding seats are arranged on both sides of the base, and two grounding through holes are arranged inside the grounding seats.
[0012] Preferably, a rubber coating sleeve is arranged on the outer wall of the base.
[0013] Beneficial effects: Compared with the prior art, the remarkable features of the present utility model are as follows:
[0014] When an external object impacts the side of the guardrail of the present utility model, since the guardrail column is rotatably connected to the base through a pin, it will rotate around the pin under the action of the impact force. During the rotation process, the shock absorption and reset spring assembly at the bottom of the guardrail column can contract and deform under the deflection of the column, and cooperate with the internal damping rod to buffer and damp the impact force, so as to reduce the damage to the guardrail and the impact object, thereby reducing losses, and solving the problem that the existing isolation fence and the base are of a fixed connection structure, and when subjected to an external force impact, only the deformation of the isolation fence can be relied on to relieve the impact, resulting in relatively large losses.

DETAILED DESCRIPTION OF THE INVENTION
[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0021] As Figures 1-4 shown, a road isolation railing base structure provided by the present utility model includes a base 1. A guardrail column 4 is arranged at the upper end of the base 1, and the lower end of the guardrail column 4 extends into the interior of the base 1. Positioning plates 8 are installed on the outer walls of the front and rear ends of the base 1. Two first connectors 10 are installed on the inner walls of the positioning plates 8. The end of the first connector 10 is rotatably connected to a first spring seat 11. A shock-absorbing return spring 12 is installed at the end of the first spring seat 11. A damping rod 13 is installed inside the shock-absorbing return spring 12. One end of the shock-absorbing return spring 12 is installed with a second spring seat 14. The end of the second spring seat 14 is rotatably connected to a second connector 15, and the second connector 15 is fixedly connected to the outer wall of the guardrail column 4. Pin seats 7 are installed on both sides above the base 1. Pins 6 are arranged on both sides of the guardrail column 4, and the guardrail column 4 is rotatably connected to the pin seats 7 through the pins 6. When the side of the guardrail is impacted by an external object, since the guardrail column 4 is rotatably connected to the base 1 through the pin 6, it will rotate around the pin under the action of the impact force. During the rotation process, the shock-absorbing return spring 12 assembly at the bottom of the guardrail column 4 can contract and deform under the deflection of the column, and cooperate with the internal damping rod 13 to buffer and damp the impact force, so as to reduce the damage to the guardrail and the impact object, thereby reducing the loss.
[0022] Furthermore, a flexible rubber sealing layer 5 is provided at the connection between the front and rear ends of the guardrail column 4 and the base 1. The flexible rubber sealing layer 5 is adhesively fixed to the connection, which can prevent dust from entering the interior of the base 1. At the same time, because it is a flexible material, it will not interfere with the deflection of the guardrail when it is impacted.
[0023] Furthermore, a sponge cushion block 16 is provided at the lower end of the guardrail column 4, and the sponge cushion block 16 is adhesively connected to the bottom surface of the base 1. The sponge cushion block 16 can ensure the stability of the guardrail during the daily use of the guardrail, and when the guardrail is impacted and deflected, it can cooperate with the damping rod 13 to play a damping and buffering effect depending on its own soft deformation characteristics.
[0024] For reasonable arrangement, the four corners of the positioning plate 8 are connected to the base 1 by screws 9. The positioning plate 8 is a detachable structure, which is convenient for the assembly of the guardrail column 4 and the shock-absorbing return spring 12 assembly.
[0025] Furthermore, grounding seats 2 are provided on both sides of the base 1. Two grounding through holes 3 are provided inside the grounding seats 2. A rubber coating sleeve is provided on the outer wall of the base 1. The grounding seats 2 are fixed to the foundation by grounding bolts, and the rubber coating sleeve on the outer wall of the base 1 enhances the anti-collision performance of the base 1 itself.
