Abstract
Description
Technical Field
[0001] This utility model relates to the field of municipal highways, specifically a safety warning device based on road guardrails. Background Technology
[0002] Highways, national roads, and other similar roads are typically equipped with guardrails. These guardrails generally consist of guardrail posts fixed to the ground and corrugated guardrail panels attached to the posts. The primary function of guardrails is to prevent vehicles from running off the road and improve driving safety. However, existing guardrails have poor visibility at night, making it difficult for drivers to detect road boundaries in time, thus posing certain safety hazards.
[0003] In addition, when a vehicle breaks down on a highway or national road, the driver often needs to carry a warning triangle and walk to a suitable location to place it, which takes a long time. However, in high-speed driving conditions, the driver is prone to secondary accidents when getting out of the car to retrieve and place the warning triangle. Utility Model Content
[0004] The purpose of this utility model is to provide a safety warning device based on road guardrails, which is simple to install, low in cost, and has a good reflective warning effect.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] A safety warning device based on a road guardrail includes:
[0007] Fixing box;
[0008] Reflective warning strips are affixed to one side of the mounting box;
[0009] The retractable reflective cone is inserted into the fixed box;
[0010] The connecting component is fixed to the bottom of the mounting box;
[0011] The connecting assembly includes a connecting sleeve and a threaded locking member. The top end of the connecting sleeve is connected to the bottom of the fixing box, and the bottom end of the connecting sleeve is used to fit onto the external guardrail post. The threaded locking member is screwed onto the outside of the connecting sleeve and is used to lock the connecting sleeve onto the external guardrail post.
[0012] Compared with the prior art, the advantages of this utility model are:
[0013] 1. By using the threaded locking parts and connecting sleeves, the fixing box is installed on the guardrail post in an adjustable orientation, so that the reflective warning strip faces the direction of the vehicle lights, thus playing a reflective warning role and ensuring that vehicles can identify the road boundary in time at night.
[0014] 2. By setting up retractable reflective cones and two C-shaped fixing blocks, the retractable reflective cones can be securely inserted into the fixing box and can be quickly removed in an emergency, avoiding the time that drivers spend searching for and setting up the warning triangle in emergency situations, effectively reducing the occurrence of secondary accidents.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:
[0020] like Figure 1-3 The diagram shown is a schematic representation of an embodiment of a safety warning device based on a road guardrail provided by this utility model:
[0021] A safety warning device based on a road guardrail includes:
[0022] Fixing box 1;
[0023] Reflective warning strip 2 is affixed to one side of the fixed box 1;
[0024] The retractable reflective cone 3 is inserted into the fixing box 1;
[0025] Connecting component 4 is fixed to the bottom of the fixing box 1;
[0026] The connecting component 4 includes a connecting sleeve 41 and a threaded locking member 42. The top end of the connecting sleeve 41 is connected to the bottom of the fixing box 1, and the bottom end of the connecting sleeve 41 is used to fit into the external guardrail post 5. The threaded locking member 42 is screwed onto the outside of the connecting sleeve 41 and is used to lock the connecting sleeve 41 onto the external guardrail post 5.
[0027] Specifically, the retractable reflective cone 3 is existing technology, such as a retractable road traffic cone disclosed in patent publication number CN210561839U, so it will not be described in detail here.
[0028] Both the connecting sleeve 41 and the fixing box 1 are made of weldable metal. The top end of the connecting sleeve 41 is welded to the bottom of the fixing box 1. Preferably, the outer sides of the connecting sleeve 41 and the fixing box 1 are also coated with anti-rust and waterproof paint.
[0029] The bottom wall of the connecting sleeve 41 is provided with several notches 410 to facilitate its deformation, and the notches 410 extend along the axial direction of the connecting sleeve 41.
[0030] Several of the aforementioned gaps 410 are arranged at circumferential intervals.
[0031] The threaded locking component 42 is a tapered nut, and the outer wall of the connecting sleeve 41 is provided with an external thread 411 that is threaded to the tapered nut.
[0032] The fixing box 1 includes a base plate 10 and two C-shaped fixing blocks 11. The two C-shaped fixing blocks 11 are respectively fixed on the top two sides of the base plate 10. The openings of the two C-shaped fixing blocks 11 are arranged opposite to each other, and a receiving groove 100 for inserting the retractable reflective cone 3 is formed between the openings of the two C-shaped fixing blocks 11.
[0033] The general usage of this utility model is as follows:
[0034] Align the bottom of the connecting sleeve 41 with the top of the outer guardrail post 5. Then, through several notches 410 at the bottom of the connecting sleeve 41, cause a certain deformation at the bottom of the connecting sleeve 41, thereby fitting it onto the outer guardrail post 5. Next, rotate the connecting sleeve 41 to adjust the orientation of the fixing box 1 so that the reflective warning strip 2 faces the direction from which the vehicle lights are emitted, ensuring the best reflective warning effect. Then, tighten the tapered nut to make the inner wall of the connecting sleeve 41 fit tightly against the outer wall of the outer guardrail post 5, thereby achieving a secure fixation.
[0035] It should be specifically noted that several utility models can be installed at intervals along the extension direction of the outer guardrail, and the installation density can be set according to the accident-proneness of the road section to achieve a better warning effect.
[0036] After installation, the user can directly take out the retractable reflective cone 3 from the fixed box 1, unfold it to a suitable height, and place it in a suitable position. This avoids the driver spending a lot of time searching for and setting up the triangle in an emergency, effectively reducing the occurrence of secondary accidents.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
