[0029] See Figure 1-9 As shown in the figure, as an embodiment of the present invention, a rollable and foldable ramp is provided, including a main plate assembly and ramp plates 2 respectively installed at the front and rear ends of the main plate assembly. The main plate assembly includes multiple main plates 1 connected in a front-to-back rotational manner. The surfaces of the main plates 1 and the ramp plates 2 are wavy surfaces extending in the front-to-back direction. The surfaces of the main plates 1 and the ramp plates 2 are provided with multiple anti-slip protrusions 3 and through holes 4. The anti-slip protrusions 3 are correspondingly located at the highest position of the wavy surface, and the through holes 4 are correspondingly located at the lowest position of the wavy surface. When the ramp is in the unfolded state, the surface of the ramp is wavy, and sand or debris can slide down from between two adjacent anti-slip protrusions 3 toward the center into the through holes 4 and finally be discharged and fall to the ground. This prevents sand or debris from accumulating on the higher side of the anti-slip protrusions 3, keeping the ramp clean and tidy, thereby improving the anti-slip effect and aesthetics of the ramp.

[0030] Of course, in other cases, it is also possible to provide multiple anti-slip ridges 3 and through holes 4 on the surface of either the main plate 1 or the ramp plate 2, and this is not a limitation.

[0031] In this embodiment, the ramp is made of aluminum, which is lighter and easier to carry; the height h of the anti-slip ridge 3 ranges from 0.8 to 1.5 mm, thus ensuring the anti-slip effect.

[0032] In this embodiment, multiple anti-slip protrusions 3 are arranged in parallel front to back and on the same plane; and / or multiple through holes 4 are arranged in a matrix, thereby ensuring the structural strength of the ramp while ensuring the discharge effect of sand or debris.

[0033] In this embodiment, the surface of the main plate 1 between two adjacent anti-slip protrusions 3 is a V-shaped concave surface 15. The angle α between the two inclined surfaces of the V-shaped concave surface 15 and the horizontal plane is in the range of 8 to 15°, thereby improving the sliding and discharge speed and effect of sand or debris.

[0034] In this embodiment, nuts 5 and screws 6 are also included. Main side plate frames 7 are fixedly installed on the left and right sides of the main body plate 1, and end side plate frames 8 are fixedly installed on the left and right sides of the ramp plate 2. Hinge holes are provided at the front and rear ends of the main side plate frame 7 and on the end side plate frame 8. The screws 6 pass through the hinge holes and lock with the nuts 5 to achieve hinge connection between the main side plate frames 7 and between the main side plate frames 7 and the end side plate frames 8.

[0035] In this embodiment, the bottom of the main body plate 1 extends downward to form two limiting plates 11 and multiple rib plates 12. The multiple rib plates 12 are located between the two limiting plates 11. The main side plate frame 7 is provided with two outer frame plates 13 and multiple protrusions 14 at one end near the main body plate 1. The multiple protrusions 14 are located between the two outer frame plates 13. The protrusions 14 are fixedly inserted between two adjacent rib plates 12. The two limiting plates 11 are respectively fixedly inserted into the inner side of the two outer frame plates 13. The limiting plates 11 and the outer frame plates 13 are provided with corresponding screw holes. The main side plate frame 7 is fixedly installed on the left and right sides of the main body plate 1 by locking the screws with the screw holes.

[0036] In this embodiment, in the unfolded state, there are gaps between the main body plate 1 and between the main body plate 1 and the ramp plate 2, and the main side plate frame 7 abuts against each other to prevent the entire ramp from collapsing.

[0037] In this embodiment, a fixed cover 9 is detachably installed on the outside between two adjacent main side plate frames 7. The fixed cover 9 includes a fan-shaped plate 91 on the outer side and an arc-shaped plate 92 on the inner side, as well as a connecting plate 93 connecting the top of the fan-shaped plate 91 and the arc-shaped plate 92. The bottom of the fan-shaped plate 91 is provided with a mounting hole 96 for screws 6 to pass through and lock. Clamping blocks 94 for clamping and limiting the main side plate frame 7 are respectively provided on the opposite sides of the fan-shaped plate 91 and the arc-shaped plate 92. Limiting holes 10 are provided on the main side plate frame 7. A limiting protrusion 95 is provided on one side of the fan-shaped plate 91. The limiting protrusion 95 is inserted and abuts against the front side of the limiting hole 10 on the latter of the two adjacent main side plate frames 7 to form a blocking limit, thereby further improving the stability of the ramp support between the two adjacent main side plate frames 7 in the unfolded state, and thus ensuring the reliability of the ramp in the unfolded state.
