[0003] To warn vehicles about safe driving, reflective film is often wrapped around steel guardrails to alert oncoming traffic. However, in the event of a vehicle collision, the steel guardrails have no anti-collision measures and are severely deformed and damaged. Therefore, given that reflective film is wrapped around steel guardrails, a steel guardrail anti-collision cap is designed to give it the dual functions of reflection and anti-collision. Utility Model Content

[0004] The purpose of this utility model is to provide a steel guardrail anti-collision headband. By setting an anti-collision headband, an anti-collision reflective layer is wrapped and assembled on the outer wall of the headband.

The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0022] Example 1

[0023] Please see Figures 1 to 5 The present invention preferably provides the following technical solution: a steel guardrail anti-collision headband, comprising: a headband, a connector hinged to the inner side of the headband for detachable assembly of the headband and the steel guardrail; and an anti-collision reflective layer covering the outer side of the headband, the anti-collision reflective layer comprising a covering layer 111, the covering layer 111 having a plurality of protrusions 212, and each protrusion 212 having a reflective coating 211 on its outer wall.

[0024] In this application, a type of anti-collision shield is provided, such as Figure 1 , 2 As shown in Figure 5, the anti-collision reflective layer is wrapped and assembled on the outer wall of the headband. The headband is then wrapped on the steel guardrail through the connector. The convex strip 212 can play a buffering and anti-collision role, while the reflective coating 211 can further provide reflection and play a warning role.

[0025] Example 2

[0026] In another embodiment of this utility model, each protrusion 212 is integrally formed with the covering layer 111, and each protrusion 212 has a spiral structure and extends a certain distance inside and outside the covering layer 111 respectively.

[0027] Furthermore, the headband includes a headband body 416 and a plurality of slots 412 formed on the headband body 416, each slot 412 being able to engage with the inner side of the protrusion 212.

[0028] Furthermore, the hoop 416 has a "C" shaped structure.

[0029] Furthermore, the outer wall of the hoop 416 is provided with an adhesive layer 411 for bonding with the inner surface of the covering layer 111.

[0030] In this embodiment, by further shaping the protrusion 212 to a certain thickness, it serves two purposes: firstly, it provides excellent anti-collision protection; secondly, the protruding portion inside the protrusion 212 can be engaged with the slot 412. Figure 1 and 2 As shown, the adhesive layer 411, combined with its bonding effect, enables the anti-collision reflective layer to be quickly and stably assembled onto the surface of the hoop 416.

[0031] Furthermore, the connectors are in two sets and symmetrically distributed on both sides of the hoop 416. Each connector includes a bushing 414 fixed on the inner wall of the hoop 416. The bushing 414 is rotatably mounted with a mounting plate 413 via a pin. The mounting plate 413 is provided with a mounting hole 415.

[0032] Through further customized connectors, such as Figure 2 and 3As shown, the mounting plate 413 can rotate and cover the outer wall of the steel guardrail. Through the action of the mounting hole 415, and with the cooperation of bolts, the headband can be fixed in the anti-collision position of the steel guardrail.

[0033] Example 3

[0034] As another embodiment of the present invention, both ends of the covering layer 111 are provided with auxiliary pouches 311, and the auxiliary pouches 311 are provided with adhesive layers. When the anti-collision reflective layer is assembled with the headband, each auxiliary pouch 311 is folded inward and adhered to the corresponding inner end of the headband 416.

[0035] Furthermore, each protrusion 212 is provided with an air bladder cavity, and each air bladder cavity is connected to the corresponding auxiliary bladder 311 through a connecting tube 213.

[0036] In this embodiment, such as Figure 1 , 2 As shown in Figures 3 and 5, after the anti-collision reflective layer is assembled on the headband, the auxiliary bladders 311 at both ends of the covering layer 111 are folded inward and placed on the ends of the headband 416. At this time, the auxiliary bladders 311 are placed in the area between the mounting plate 413 and the headband 416. Since the protrusion 212 has an air bladder cavity inside, when the protrusion 212 is impacted, the air bladder cavity is compressed and the gas is squeezed to the two auxiliary bladders 311 at the inner end of the auxiliary bladder 311, which expands, making the mounting plate 413 cover the guardrail more tightly. At the same time, the protrusion 212 completes an elastic buffering at the impact point.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part. Among these, there are various ways to install detachably, such as by using a combination of plug-in and snap-fit, or by using bolts for connection, etc.

[0038] In addition, all the connections / connections mentioned in the article do not refer to direct connection of components, but rather to the formation of a better connection structure by adding or removing connecting accessories according to the specific implementation situation.

[0039] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model.
