Description

Technical Field

[0001] This utility model relates to the field of traffic safety facilities technology, specifically to a traffic road reflective sign. Background Technology

[0002] With the continuous development of road traffic technology, road traffic volume has increased accordingly, and road safety issues at night or in low-light conditions have become increasingly prominent. Therefore, reflective markings are currently installed on road surfaces or curbs to alert drivers to road conditions. Existing traffic signs typically use reflective film directly affixed, for example, pasted onto a signboard which is then installed on the road. However, these signs are bulky, inconvenient to install, and take up considerable space, resulting in poor portability. Another method involves directly affixing reflective strips to guardrails; however, reflective strips installed this way have poor reflectivity on straight roads. Since the reflective strips are located on both sides of the road, drivers' line of sight is forward, and the reflected light is outside their line of sight. Furthermore, they are easily peeled off due to rain, temperature changes, and other environmental factors, leading to increased maintenance costs.

[0003] Therefore, there is an urgent need to design a new type of reflective road marking that is portable while improving road safety. Utility Model Content

[0004] The purpose of this utility model is to provide a traffic road reflective sign with a reasonable structural design that is suitable for various road scenarios (such as guardrails, tunnel walls, etc.) and can be easily installed.

[0005] The technical solution adopted by this utility model to solve the above problems is: a traffic road reflective sign, including a base, a substrate and a reflective film pasted on the substrate, the base having an installation hole and being damped and hinged to the substrate, and the substrate having a groove for pasting the reflective film.

[0006] Preferably, the base is vertically provided with a hinge seat, the base plate is provided with a hinge plate, the hinge plate is hinged to the hinge seat by bolts and nuts, and the front and rear sides of the hinge plate are respectively provided with a first countersunk hole adapted to the bolt head and a second countersunk hole adapted to the nut.

[0007] Preferably, the hinge seat has a hinge groove, and inclined surfaces are provided on both sides of the hinge groove. The hinge plate is oscillating within the hinge groove, and the oscillation range is limited to the area between the inclined surfaces on both sides.

[0008] Preferably, the hinge seat has several reinforcing ribs on both the front and rear surfaces.

[0009] Preferably, the bolts are internal hex bolts.

[0010] Preferably, the substrate has grooves on both the front and back sides.

[0011] Preferably, the substrate has a through hole, which is disposed within a groove.

[0012] Preferably, the groove is circular.

[0013] Preferably, the through hole is located at the center of the groove.

[0014] Preferably, the substrate has arrow protrusions pointing to the hinge point on both the front and back sides.

[0015] Compared with the prior art, this utility model has the following advantages and effects:

[0016] This invention improves the portability, stability, and durability of reflective traffic signs through a rational structural design. Specifically, the damping hinge structure between the base and the substrate allows the substrate to be freely adjusted at the angle after installation to meet the needs of different road scenarios. Grooves on the substrate effectively protect the reflective film, preventing it from detaching due to rain or environmental factors, thus extending the lifespan of the sign. Simultaneously, the friction damping design between the hinge and the substrate ensures that the substrate is fixed after adjustment to the desired angle, preventing accidental swaying caused by external factors (rain, snow, strong winds), and improving the stability of the sign. Furthermore, the through-hole design on the substrate effectively eliminates air bubbles generated during the application of the reflective film, ensuring a tight bond between the film and the substrate. The raised arrows and angle scale lines facilitate precise adjustment of the angle of each set of reflective signs by installers, ensuring the overall integrity of multiple sets of reflective signs installed simultaneously for optimal visual effect. This provides drivers with more effective traffic reminders in low-light environments, further improving road driving safety. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0023] Example:

[0024] See Figure 1 - Figure 4 This embodiment relates to a reflective road marking, specifically used for road traffic safety marking. It is applicable to various road scenarios such as highways, urban roads, guardrails, and tunnel walls, and is used to improve road visibility and safety at night or in low-light environments. The reflective marking specifically includes a base 11, a substrate 12, and a reflective film 13 adhered to the substrate 12. The base 11 has mounting holes 14 and is dampedly hinged to the substrate 12. The substrate 12 has grooves 15 for adhering the reflective film 13.

[0025] Specifically, in this embodiment, the mounting holes 14 of the base 11 can be fixed to various fixed base surfaces using threaded fasteners or other connectors, such as guardrails on both sides of national highways, median strips on expressways, guardrails between motor vehicle and non-motor vehicle lanes on urban roads, and wall panels on both sides of tunnels. This adapts to various road conditions and offers good portability. The base 11 and the base plate 12 are damped hinged, allowing the base plate 12 to swing along the hinge point. By adjusting the swing direction of the base plate 12, for example, by fixing the base plate 12 to a guardrail on an urban road, the base plate 12 can be swung to the motor vehicle lane or one side of the motor vehicle lane. Only one row needs to be installed to meet the warning function for both motor vehicle and non-motor vehicle drivers. At the same time, the reflective film 13 is pasted into the groove 15 of the base plate 12, effectively preventing rainwater from directly washing away the edges of the reflective film 13 and causing it to fall off, thus extending the service life of the reflective film 13. In addition, several reinforcing ribs 16 are provided on both the front and rear surfaces of the hinge seat 21. The reinforcing ribs 16 can enhance the strength of the hinge seat 21 and provide effective protection for the hinge plate 22 hinged therein.

[0026] The base 11 is vertically provided with a hinge seat 21, and the base plate 12 is provided with a hinge plate 22. The hinge plate 22 is hinged to the hinge seat 21 by bolts 23 and nuts 24. The front and rear sides of the hinge plate 22 are respectively provided with a first countersunk hole 25 adapted to the head of the bolt 23 and a second countersunk hole 26 adapted to the nut 24. The threaded connection of the bolts 23 and nuts 24 makes the hinge seat 21 and the hinge plate 22 in close contact. When the base plate 12 swings, friction is generated between the hinge plate 22 and the hinge seat 21, forming a damping hinge effect, so that the base plate 12 can be fixed after swinging to the required angle, preventing it from swinging unexpectedly due to external forces (rain, snow, strong winds). In this embodiment, the bolt 23 is an internal hexagon bolt 23, and the nut 24 is a hexagonal nut 24. The first countersunk hole 25 is provided with a circular groove adapted to the head of the bolt 23, and the second countersunk hole 26 is provided with a regular hexagonal hole adapted to the nut 24. This allows the nut 24 to be contained within the second countersunk hole 26 and not rotate, which facilitates the tightening of the bolt 23 using an Allen wrench.

[0027] The hinge base 21 has a hinge groove 31, and inclined surfaces 32 are provided on both sides of the hinge groove 31. The hinge plate 22 is oscillating within the hinge groove 31, and the oscillation range is limited between the inclined surfaces 32 on both sides. This structure can limit the oscillation range of the base plate 12, preventing it from exceeding a predetermined angle (e.g., the angle when the outer edge of one side of the base plate 12 is parallel to the base 11). When the base 11 is installed on the guardrail, the angle limitation prevents it from protruding beyond the guardrail after oscillation or reduces the length of the protruding parts relative to the two sides of the guardrail, thereby reducing encroachment on the motor vehicle or non-motor vehicle lane and avoiding skidding of vehicles.

[0028] The substrate 12 has grooves 15 on both its front and back sides. The reflective film 13 can be pasted into any one of the grooves 15 or simultaneously into two sets of grooves 15 to accommodate bidirectional traffic flow. The substrate 12 has through holes 33 located within the grooves 15. These through holes 33 allow air bubbles between the reflective film 13 and the substrate 12 to escape during the pasting process, ensuring a tight bond between the reflective film 13 and the substrate 12. The grooves 15 are circular to better accommodate the reflective film 13, and the through holes 33 are located at the center of the grooves 15.

[0029] The substrate 12 has arrow protrusions 34 pointing to the hinge point on both sides, which allows for rough adjustment when adjusting the swing angle of the substrate 12. Correspondingly, angle scale lines 35 can also be set on the hinge seat 21. By setting angle scale lines 35 on the hinge seat 21, the installer can precisely adjust the angle of each set of substrates 12, ensuring uniformity when adjusting the angle of the substrates 12, increasing the overall integrity when installing multiple sets, and ensuring a better visual effect when installing multiple sets of reflective signs.

[0030] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
