However, traditional curb ramps are mostly fixed, one-piece structures that are bulky and take up a lot of space when not in use, making them inconvenient for home storage or vehicle transport, especially in terms of flexibility in travel scenarios. Furthermore, the locking mechanisms of some foldable curb ramps are complex, making them prone to loosening after folding and cumbersome to unfold, thus affecting their efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a foldable and portable curb ramp that allows for quick folding, thus solving the problem of cumbersome unfolding operations.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A foldable and portable curb ramp includes a ramp one and a ramp two, which are movably connected by a hinge. A strip is hinged to the outside of ramp one, and a frame is fixed to the outside of ramp two. The frame has a slot, through which the strip is inserted into the frame. A spring is fixed to the inner wall of the frame, and an arc-shaped block is fixed to the end of the spring. A limiting groove is formed on the side of the strip that is close to the arc-shaped block. The limiting groove is adapted to the shape of the arc-shaped block, and the arc-shaped block is inserted into the limiting groove. A pull block for moving the arc-shaped block is fixed to the bottom of the arc-shaped block.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a foldable and portable curb ramp.

[0015] Example 1: Combination Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the present invention provides a foldable and portable curb ramp, including a first ramp 1 and a second ramp 2. The first ramp 1 and the second ramp 2 are connected by a hinge 14. An insert 8 is hinged to the outside of the first ramp 1, and a frame 9 is fixed to the outside of the second ramp 2. A slot 11 is provided on the frame 9. The insert 8 is inserted into the frame 9 through the slot 11, so as to realize the folding and storage of the curb ramp, reduce the floor space occupied when not in use, and make it convenient to carry and store. A spring 12 is fixed to the inner wall of the frame 9. An arc-shaped block 13 is fixed to the end of the spring 12. A limiting groove 10 is formed on the side of the insert 8 that is close to the arc-shaped block 13. The limiting groove 10 is adapted to the shape of the arc-shaped block 13. The arc-shaped block 13 is inserted into the limiting groove 10. A pull block 15 for removing the arc-shaped block 13 from the limiting groove 10 is fixed to the bottom of the arc-shaped block 13. After the insert 8 is inserted into the frame 9, it contacts the arc-shaped block 13, causing the arc-shaped block 13 to move to the other side. Then the insert 8 continues to move, and the limiting groove 10 and the arc-shaped block... 13 are located on the same plane. Spring 12 pushes arc block 13 to insert it into limit groove 10 and lock insert 8. This allows ramp 1 and ramp 2 to be folded to reduce the floor space. When ramp 1 and ramp 2 need to be unfolded, pull block 15 to move arc block 13. Then arc block 13 disengages from limit groove 10, insert 8 can be taken out, and ramp 1 and ramp 2 can be unfolded. This ensures stable locking in the folded state. When unfolding, simply pull block 15 to release the lock. The operation is simple and convenient.

[0016] Specifically, both ramp 1 and ramp 2 have threaded rods 6 fixedly connected to their bottoms. Support legs 7 are threadedly connected to the threaded rods 6. By rotating the support legs 7 to connect with the threaded rods 6, the height of the support legs 7 can be adjusted to accommodate steps of different heights, thereby improving the equipment's versatility and adaptability to different usage scenarios.

[0017] Furthermore, both ramp 1 and ramp 2 have anti-slip rubber pads affixed to their upper surfaces. The anti-slip rubber pads have horizontally arranged anti-slip ridges on their surfaces, which can effectively increase the friction of the contact surface, prevent wheelchairs and pedestrians from slipping when passing through, and improve the safety of the curb ramps during use.

[0018] As can be seen from the embodiments, combining the folding function with the locking function not only solves the problems of easy loosening after folding and cumbersome locking operation of traditional curb ramps, but also reduces the volume after folding, while taking into account both ease of operation and structural stability.

[0019] Example 2: Combination Figure 1 and Figure 4 As shown, based on Embodiment 1, both ramp 1 and ramp 2 have extension plates 3 inserted at their front ends. The extension plates 3 can be flexibly adjusted in length according to the actual length of the steps to adapt to different specifications of steps.

[0020] Specifically, the extension plate 3 has multiple threaded holes 4, and ramp 1 and ramp 2 each have through holes that are adapted to the threaded holes 4 on the corresponding extension plate 3. Ramps 1 and ramp 2 are connected to the corresponding extension plates 3 by locking bolts 5. The extension plates 3 at the front end of ramps 1 and ramp 2 are pulled outward to the required length, the threaded holes 4 on the extension plate 3 are aligned with the through holes on the ramps, and the locking bolts 5 are screwed into the threaded holes 4 through the through holes to fix the extension plate 3 to the ramps. This can securely fix the extension plate 3 after adjustment, prevent relative slippage during use, and ensure structural stability.

[0021] As can be seen from the above embodiments: First, take out the portable curb ramp that is in the folded storage state. When it needs to be unfolded for use, pull the pull block 15 on the frame 9. The pull block 15 drives the arc block 13 to move against the elastic force of the spring 12, so that the arc block 13 disengages from the limiting groove 10 on the insert 8. Then, take the insert 8 out of the slot 11 of the frame 9. Unfold the ramp 1 and ramp 2 to a suitable angle through the hinge 14. According to the height of the step to be used, rotate the support leg 7 on the threaded rod 6 at the bottom of ramp 1 and ramp 2. Adjust the height of the support leg 7 by using the threaded connection between the support leg 7 and the threaded rod 6, so that the curb ramp as a whole adapts to the height of the step.
