[0020] A vehicle scratch-resistant self-recovering tunnel profile belt and a method of use, such as Figures 1 to 4 As shown, the tunnel contour band 8 is formed by multiple segments installed successively on the tunnel wall along a certain clearance limit of the tunnel cross section. Each segment is composed of a skeleton at both ends, a thin plate 5 connecting the skeletons at both ends, and a light strip 6 arranged in the skeletons at both ends. The thin plate 5 is a reflective or self-luminous thin plate, and the outer side of the thin plate 5 is wrapped with a protective film 51; the skeleton at each end is composed of a mounting handle 1, a horizontal rod 3 installed under the mounting handle, and an arc rod 4 installed under the horizontal rod.

[0021] The multiple segments of this embodiment refer to three types of types, namely, multiple Type I contour bands, multiple Type II contour bands, or multiple Type III contour bands. Therefore, the tunnel contour band 8 involved in this embodiment is formed by multiple Type I contour bands, multiple Type II contour bands, or multiple Type III contour bands being installed successively on the tunnel wall along a certain clearance limit of the tunnel cross section; moreover, a notch 43 is provided at the bottom of the arc rod 4 in each end skeleton of each Type I contour band or each Type II contour band, so the notch 43 can form the arc rod 4 into a left limb 42 and a right limb 41, and the thin plate 5 is connected between the left limbs 42 at both ends and between the right limbs 41 at both ends.

[0022] Each end frame of the type I contour belt includes a mounting handle 1, the bottom end of the mounting handle is fixed to the middle of the horizontal rod 3, and the upper end of the left limb 42 and the upper end of the right limb 41 constituting the arc rod 4 are respectively fixed to the two ends of the horizontal rod 3; in this way, when the type I contour belt is scratched by an oncoming vehicle, the arc rod 4 follows the direction of the vehicle's travel, and under the action of the notch 43, the left limb 42 and the right limb 41 both form independent elastic bending deformations, at which time the arc rod 4 will drive the thin plate 5 and the protective film 51 to deform synchronously accordingly; when the type I contour belt is separated from the vehicle scratch, the arc rod 4 releases its elasticity to restore the left limb 42 and the right limb 41 to their original positions, at which time the arc rod 4 will drive the thin plate 5 and the protective film 51 to restore their original positions synchronously accordingly.

[0023] Each end skeleton of the Type II contour belt includes a mounting handle 1, the bottom end of the mounting handle and the middle part of the horizontal rod 3 are rotatably mounted via a rotating shaft 31 and a circular hole, and the upper end of the left limb 42 and the upper end of the right limb 41 constituting the arc rod 4 are respectively fixed on the two ends of the horizontal rod 3, and a spring 7 connected to each other is provided between the lower end of the left limb 42, the lower end of the right limb 41 and the bottom end of the mounting handle 1; in this way, when the Type II contour belt is scratched by an oncoming vehicle, the arc rod 4 and the horizontal rod 3 will rotate together relative to the bottom end of the mounting handle 1 in the direction of the vehicle, and drive the thin plate 5 and the protective film 51 to deform synchronously accordingly, and also drive the spring 7 to form a stretch; when the Type II contour belt is scratched by the vehicle, the stretched spring 7 automatically resets, and will drive the arc rod 4 and the horizontal rod 3 to rotate together relative to the bottom end of the mounting handle 1 to return to their original position, and drive the thin plate 5 and the protective film 51 to also return to their original state synchronously accordingly.

[0024] Each end skeleton of the Type III contour belt includes a mounting handle 1, the bottom end of the mounting handle is fixed to one end of the horizontal rod 3, that is, the horizontal rod is exactly half of the horizontal rod of the two types of tunnel contour belts 8 mentioned above, and the arc rod 4 of the Type III contour belt is also equivalent to the right limb or left limb of the two types of tunnel contour belts 8 mentioned above. The upper end of the arc rod 4 is rotatably mounted on the other end of the horizontal rod 3 through the rotating shaft 31 and the circular hole, and the lower end of the arc rod 4 and the bottom end of the mounting handle 1 are provided with a spring 7 connected to each other; in this way, when the Type III contour belt is scratched by an oncoming vehicle, the arc rod 4 will rotate relative to the horizontal rod 3 along the direction of vehicle travel, and drive the thin plate 5 and the protective film 51 to deform synchronously accordingly, and also drive the spring 7 to be compressed; when the Type III contour belt is free from vehicle scratches, the compressed spring 7 automatically resets, and will drive the arc rod 4 to rotate relative to the horizontal rod 3 to return to its original position, and drive the thin plate 5 and the protective film 51 to return to their original state synchronously accordingly.

[0025] The mounting handle 1 is a T-shaped block made of plastic material, the upper end of which is fixed to the tunnel wall with bolts, and the lower end is connected to the horizontal rod 3 and the arc rod 4 in three forms: the mounting handle 1 of the type I profile belt and the cross-sections of the horizontal rod 3 and the arc rod 4 are in the same plane and are consolidated with each other. The type I profile belt is suitable for tunnels with two-way traffic; the mounting handle 1 of the type II profile belt and the cross-sections of the horizontal rod 3 and the arc rod 4 are two planes close together, the two ends of the horizontal rod 3 are consolidated with the upper end of the arc rod 4, and a cylindrical rotating shaft 31 is provided in the middle of a pair of horizontal rods 3 perpendicular to the inner side of the horizontal rod. The cylindrical rotating shaft passes through the circular hole reserved at the lower part of the mounting handle 1, so that the horizontal rod 3 and the arc rod 4 can rotate together around the rotating shaft 31. The outer end of the cylindrical rotating shaft is provided with a pin 32 for fixing. Each type II profile belt can be consolidated by the two ends of a longitudinal connecting rod 2. The type II profile belt is suitable for two-way traffic tunnels; the mounting handle 1 and the horizontal rod 3 and the arc rod 4 of the type III profile belt are two planes close together. The bottom end of the mounting handle 1 and one end of the horizontal rod 3, that is, the inner end, are consolidated into a fixed skeleton. The other end of the horizontal rod 3, that is, the outer end, is perpendicular to the inner side of the horizontal rod and a cylindrical rotating shaft 31 is provided. The cylindrical rotating shaft passes through the circular hole reserved at the upper end of the arc rod 4, so that the horizontal rod 3 and the arc rod 4 can rotate together around the rotating shaft. The outer end of the cylindrical rotating shaft 31 is provided with a pin 32 for fixing. The type III profile belt is suitable for one-way traffic tunnels.

[0026] The longitudinal connecting rod 2 is made of a plastic material with a rectangular or circular cross-section and is mainly connected to a set of mounting handles 1 of each tunnel profile belt. That is, the three types of tunnel profile belts can all use the longitudinal connecting rod 2 and form a stable structure before the tunnel profile belt is installed on the tunnel wall; when the three types of tunnel profile belts do not use the longitudinal connecting rod 2, the packaging, storage and transportation space of the product can be saved, and a stable structure can also be formed when installed on the tunnel wall.

[0027] The arc rod 4 has a rectangular cross-section, and the I-type profile belt is required to have high elasticity and is made of nylon (PA series) plastic. The nylon plastic has excellent strength, elasticity, and relatively good wear resistance, heat resistance, and chemical corrosion resistance. It can also be made of polyethylene, polypropylene polyester, ABS and sulfide polyethylene materials.

[0028] The arc rod 4 of the type I contour belt is designed so that when the arc rod on the oncoming side of a vehicle is scratched or detached from the scratch, the arc rod on each side, that is, the left limb or the right limb, drives the thin plate 5 and the plastic film 51 to deform accordingly or restore to their original state, thereby avoiding damage to the tunnel contour belt; a notch 43 is left at the lowest end of the arc rod 4. When a vehicle scratches, the arc rods on both sides, that is, the left limb and the right limb, can deform independently to avoid mutual pulling and damage to the thin plate 5 and the protective film 51.

[0029] The reflective or self-luminous body is formed by spraying a long afterglow material on a reflective film or a plastic sheet, and can reflect vehicle lights or continue to emit light for a period of time in the absence of lighting, which is beneficial to the safe passage of vehicles and pedestrians.

[0030] The protective film 51 is a flexible plastic film with strong corrosion resistance and flame retardancy, and covers the outer surface of the self-luminous body sheet.

[0031] The light strip 6 is a plastic tube with built-in LED lights 61, which can be used for auxiliary lighting of the tunnel and as an excitation light source for the reflective or self-luminous body of the outline. The light strip 6 can be placed in the middle of the upper part of the tunnel outline, or on both sides of the upper part of the tunnel outline. The light strip 6 of the type II outline and type III outline can be placed at the bottom end of the arc rod 4, and its open diffusion angle is 1 / 4. The angle of the profile is determined by the installation position of the profile. Since the tunnel is provided with multiple profiles in the longitudinal direction, the diffusion angle is required to be The diffused LED light can illuminate the ground projection width of no less than half of the distance between adjacent ring contour strips.

[0032] The above description is only a specific embodiment of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included in the protection scope of the present invention.
