Description

Foldable boat bottom plate

Technical Field

The invention relates to the field of boats, in particular to a foldable boat bottom plate.

Background

The main material of inflatable boat is rubber or PVC, and after the inside packing has the air, can make the hull float on the surface of water, except the totally manual inflatable boat, also can add the propeller at the stern to improve inflatable boat's navigation speed. Compared with a hard-shell boat, the inflatable boat not only greatly reduces the manufacturing cost, but also is more convenient to clean, transport and store. The inflatable boat has wide application, and is a military boat used for troops to fight at river-crossing sea, a flood prevention boat used for flood prevention and rescue of armed police, a completely manual kayak, a drift boat used for life and entertainment, a fishing boat and the like.

The existing inflatable boat bottom plate mainly comprises two types, one type is a soft material bottom plate represented by rubber or PVC materials, the bottom plate and the boat body are of an integrated structure, the soft material bottom plate can be filled with air, and the bottom plate can be formed after the boat body is inflated, so that the bottom plate can be folded along with the boat body, and is convenient to carry and store. The disadvantage is that the material is soft, even if the inner part is filled with air, the person still collapses at the trampling part after trampling on the bottom board of the boat, just like trampling on cotton, the person is easy to walk unstably on the bottom board of the boat, and even has a certain degree of potential safety hazard after launching. In addition, the hard bottom board is made of plastic or metal and is integrated with the ship body, and the advantage that the bottom board is made of hard material, so that people can step on the bottom board to feel firm and stable and walk conveniently. However, the hard bottom board is different from the soft bottom board, and the hard bottom board is made of a material which cannot be folded, still occupies a larger volume after the ship body is deflated, and is inconvenient to store and transport.

In conclusion, the two bottom plates cannot meet the use requirements of people on the inflatable boat and need to be improved.

Disclosure of Invention

The invention aims to solve the problems and provide a foldable boat bottom plate which is firm and stable and is convenient to carry and store.

In order to achieve the purpose, the invention discloses a foldable boat bottom plate, which comprises a bottom plate body arranged at the bottom of an inflatable boat cabin, and is structurally characterized in that: the bottom plate body comprises a plurality of bottom plate components which are connected together in a front-back mode, and a hinge portion which can enable the two bottom plate components to rotate relatively is arranged between every two adjacent bottom plate components, so that the bottom plate body is in a folded state.

When the bottom plate body is used, the bottom plate body can be installed at the bottom of a cabin of an inflatable boat after being unfolded, after the bottom plate body is used, the bottom plate assembly can be folded by the aid of the hinge parts, the bottom plate body not only has the advantages of being foldable, convenient to carry and store, and the bottom plate body also has the advantages of being hard, firm and stable, convenient to walk, and capable of guaranteeing safety of the boat after being launched.

Regarding to the first implementation mode of the hinge part, the hinge part comprises a sliding groove which is positioned on the rear side surface of the bottom plate component and extends left and right, the sliding groove is arc-shaped, a limiting block is arranged above the sliding groove, and a clamping groove with a downward opening is formed in the lower side of the limiting block; the hinged part also comprises a clamping tongue fixedly arranged on the front side of the bottom plate component, the clamping tongue is clamped in a sliding groove of the adjacent front side bottom plate component, the lower side of the clamping tongue is provided with an arc surface in sliding fit with the sliding groove, the upper side of the clamping tongue is fixedly provided with a spherical crown rotating tongue, and the spherical crown rotating tongue is abutted against the clamping groove and is in rotating fit with the clamping groove. After the structure is adopted, the hinged parts are arranged on the front side and the rear side of the bottom plate component and are of an integrated structure with the bottom plate component, the assembled and combined bottom plate body is only required to insert the clamping tongue and the spherical crown rotating tongue from the side part of the sliding groove, the installation is convenient, and the hinged parts and the bottom plate component are of an integrated structure, so that the assembled and combined bottom plate body can bear large downward pressure, and is solid, durable and not easy to damage.

In a second embodiment of the hinge portion, the hinge portion includes a hinge mounted between the front and rear base plate assemblies, and two fixing portions of the hinge are respectively fixedly mounted on the two adjacent base plate assemblies. After adopting above-mentioned structure, the relative rotation of two adjacent bottom plate subassemblies is realized through the hinge, adopts the hinge structure, low cost, and bottom plate subassembly processing cost is lower.
