Description

Technical Field

[0001] This utility model relates to the field of ramps, specifically a four-fold aluminum alloy ramp. Background Technology

[0002] The main entrances are equipped with thresholds, and ramps are used to facilitate passage for wheelchair users. Existing ramps are mainly permanent wheelchair ramps made of poured concrete or integral aluminum alloy wheelchair ramps, and there are also some convenient ramps that can be folded and stored.

[0003] For example, patent CN219196539U discloses an adjustable wheelchair ramp, including two sets of hinged ramp bodies and a guard plate connected to the two sets of ramp bodies. Two hinged connecting ramps are connected between the two sets of ramp bodies. A first locking block is fixedly connected to one end of the connecting ramp and one end of one set of ramp bodies. A second locking block that engages with the first locking block is fixedly connected to one end of the connecting ramp and one end of the other set of ramp bodies.

[0004] The aforementioned patent, by setting connecting ramps (the number of connecting ramps can be multiple) on two sets of ramp bodies, allows the user to adjust the length of the ramp body by using a plug rod to limit the first and second locking blocks, thus forming a whole between the connecting ramp and the ramp body, thereby increasing the length of the ramp body and facilitating wheelchair passage, thus enhancing the practicality of the connecting ramp. However, the disadvantage of the aforementioned patent is that the ramp body and the connecting ramp need to be connected by a plug rod, and when not in use, there are multiple unconnected parts, making it inconvenient to carry.

[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0031] Please see Figure 1-2 A four-fold aluminum alloy ramp, comprising a left A ramp assembly 100, a left B ramp assembly 200, a right A ramp assembly 300, and a right B ramp assembly 400. The left A ramp assembly 100 and the left B ramp assembly 200 are rotatably connected by a rotatable connection assembly 700; the right A ramp assembly 300 and the right B ramp assembly 400 are also rotatably connected by a rotatable connection assembly 700; at the same time, the left A ramp assembly 100 and the right A ramp assembly 300 are rotatably connected by a hinge 600. When this solution is put into use, the left A ramp component 100, the left B ramp component 200, the right A ramp component 300, and the right B ramp component 400 unfold to form a ramp for pedestrians or wheelchairs to pass through. When not in use, such as Figure 14 As shown, firstly, the left A ramp assembly 100 is folded along the hinge 600 so that the left A ramp assembly 100 rests on the right A ramp assembly 300; then, the left B ramp assembly 200 is folded along the rotatable connection assembly 700 so that the left B ramp assembly 200 rests on the left A ramp assembly 100; then, the right B ramp assembly 400 is folded along the rotatable connection assembly 700 so that the right B ramp assembly 400 rests on the right A ramp assembly 300, thus forming a folded configuration of four ramp assemblies. When this four-fold aluminum alloy ramp is folded or stored, there are no separate, unconnected parts. Parts are not easily lost and it is easy to carry. This avoids the situation where the four-fold aluminum alloy ramp cannot be used normally if a part is lost. In this solution, the structures of the left A ramp assembly 100, the left B ramp assembly 200, the right A ramp assembly 300, and the right B ramp assembly 400 are similar; like Figure 3-4 As shown, the left A ramp assembly 100 includes a left A outer frame 101, a left A inner frame 102, and a ramp slab 500 connected between the two. Specifically, both the outer left A frame 101 and the inner left A frame 102 have left A slots 103 for installing ramp slabs 500 on their inner sides; the two ends of the ramp slabs 500 are respectively inserted into the left A slots 103 of the outer left A frame 101 and the inner left A frame 102; the outer left A frame 101 and the inner left A frame 102 are also fixedly connected to the ends of the ramp slabs 500 by ramp fixing bolts 501. The outer top of the left A outer frame 101 is provided with a left A guard 104 extending upward; the left A guard 104 mainly serves to prevent the wheels of the wheelchair from running to the outside of the aluminum alloy ramp.

[0032] like Figure 5 As shown, the left B ramp assembly 200 includes a left B outer frame 201, a left B inner frame 202, and a ramp slab 500 connected between the two. Specifically, both the outer left B frame 201 and the inner left B frame 202 have left B slots 203 for installing ramp slabs 500 on their inner sides; the two ends of the ramp slab 500 are respectively inserted into the left B slots 203 of the outer left B frame 201 and the inner left B frame 202; at the same time, the outer left B frame 201 and the inner left B frame 202 are also fixedly connected to the ends of the ramp slab 500 by ramp fixing bolts 501. The outer top of the left B outer frame 201 is provided with a left B guard 204 extending upward; the left B guard 204 also mainly serves to prevent the wheels of the wheelchair from running to the outside of the aluminum alloy ramp. Meanwhile, when this solution is deployed, the first end of the left B-side 204 abuts against the tail end of the left A-side 104, thereby keeping the left A-ramp assembly 100 and the left B-ramp assembly 200 horizontal when deployed.

[0033] like Figure 6 As shown, the right A ramp assembly 300 includes a right A outer frame 301, a right A inner frame 302, and a ramp slab 500 connected between the two. Specifically, both the outer right A frame 301 and the inner right A frame 302 have right A slots 303 for installing ramp slabs 500 on their inner sides; the two ends of the ramp slabs 500 are respectively inserted into the right A slots 303 of the outer right A frame 301 and the inner right A frame 302; the outer right A frame 301 and the inner right A frame 302 are also fixedly connected to the ends of the ramp slabs 500 by ramp slab fixing bolts 501. The outer top of the right A outer frame 301 is provided with a right A retaining edge 304 extending upward; the right A retaining edge 304 mainly serves to prevent the wheels of the wheelchair from running to the outside of the aluminum alloy ramp.

[0034] like Figure 7 As shown, the right B ramp assembly 400 includes a right B outer frame 401, a right B inner frame 402, and a ramp slab 500 connected between the two. Specifically, both the outer right B frame 401 and the inner right B frame 402 have right B slots 403 for installing ramp slabs 500 on their inner sides; the two ends of ramp slabs 500 are respectively inserted into the right B slots 403 of the outer right B frame 401 and the inner right B frame 402; at the same time, the outer right B frame 401 and the inner right B frame 402 are also fixedly connected to the ends of ramp slabs 500 by ramp fixing bolts 501. The outer top of the right B outer frame 401 is provided with a right B guard 404 extending upward; the right B guard 404 also mainly serves to prevent the wheels of the wheelchair from running to the outside of the aluminum alloy ramp. Meanwhile, when this solution is deployed, the first end of the right B retaining edge 404 abuts against the tail end of the right A retaining edge 304, thereby keeping the right A ramp assembly 300 and the right B ramp assembly 400 horizontal when deployed.

[0035] In this plan, such as Figure 1 and 8 As shown, the left A inner frame 102 of the left A ramp assembly 100 and the right A inner frame 302 of the right A ramp assembly 300 are connected by a hinge 600; the base of the hinge 600 is fixedly connected to the left A inner frame 102 and the right A inner frame 302 by bolts respectively. It is worth noting that in this design, the hinge 600 is not located at the exact center of the left A ramp assembly 100 and the right A ramp assembly 300; its installation position is more biased towards the right A ramp assembly 300. This allows the left A-side of the left A ramp assembly 100 to be positioned outside the right A-side of the right A ramp assembly 300 when the right A ramp assembly 300 is placed on top of the left A ramp assembly 100 (the left A ramp assembly 100 and the right A ramp assembly 300 are of equal width). At this time, the right A ramp assembly 300 can be closer to the left A ramp assembly 100, resulting in a smaller overall space occupied when folded. As shown in Figure 2, the rotating connection assembly 700 includes two first rotating connection seats 701 and a second rotating connection seat 702 located between the two first rotating connection seats 701. The first rotating connection seats 701 and the second rotating connection seat 702 are rotatably connected by a rotating connection bolt 703. Taking the left A ramp assembly 100 and the left B ramp assembly 200 as examples, The bottoms of the left A outer frame 101 and the left B outer frame 201 are rotatably connected by a set of rotatable connecting components 700, wherein two first rotatable connecting seats 701 are fixedly welded to the bottom of the left B outer frame 201, and the second rotatable connecting seat 702 is fixedly welded to the bottom of the left A outer frame 101. The bottoms of the left A inner frame 102 and the left B inner frame 202 are rotatably connected by a set of rotatable connecting components 700, wherein two first rotatable connecting seats 701 are fixedly welded to the bottom of the left B inner frame 202, and the second rotatable connecting seat 702 is fixedly welded to the bottom of the left A inner frame 102. like Figure 9-10 As shown, the ramp 500 includes several ramp components 510. Each ramp component 510 is made of aluminum alloy and is generally rectangular. The top of each ramp component 510 has anti-slip textures 511. Meanwhile, three paving reinforcement beams 512 are spaced apart at the bottom of the paving assembly 510. The front end of the reinforcing beam 512 at the first end of the paving assembly 510 is provided with a docking groove 513, and the rear end of the reinforcing beam 512 at the rear end of the paving assembly 510 is provided with a docking rib 514 extending forward; at the same time, through holes for the paving fixing bolts 501 to pass through are also provided at the left and right ends of the paving assembly 510. When several paving assemblies 510 are combined, the mating ribs 514 of the paving assembly 510 are inserted into the mating grooves 513 of the adjacent paving assembly 510, thereby improving the connection strength between the adjacent paving assemblies 510. like Figure 11-12 As shown, it is worth noting that overlapping ramp slabs 520 are installed at the tail ends of the left B ramp assembly 200 and the right B ramp assembly 400. The bottom of the overlapping paving 520 is also provided with several reinforcing beams 512. At the same time, the front end of the reinforcing beam 512 at the first end of the overlapping paving 520 is provided with a connecting groove 513, and the tail end of the overlapping paving 520 is inclined downward. In use, the overlapping paving 520 overlaps at the highest point of the steps.

[0036] like Figure 13 As shown, when using this utility model, the tail of the four-fold aluminum alloy ramp is attached to the highest point of the steps, and the head of the four-fold aluminum alloy ramp is placed and attached to the highest point of the steps; at this time, the bottom of the four-fold aluminum alloy ramp is attached to the edge of the middle steps. When storing, the four-fold aluminum alloy ramp can be folded to form a four-ramp assembly, making it easy to store.

[0037] Meanwhile, in this solution, reinforcing plates 800 are provided on the bottom inner sides of the left A inner frame 102, left B inner frame 202, right A inner frame 302, and right B inner frame 402. These reinforcing plates 800 are mainly used to improve the structural strength of the respective left A inner frame 102, left B inner frame 202, right A inner frame 302, and right B inner frame 402.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
