[0002] Portable boats are generally divided into foldable and detachable types. Traditional foldable boats are mostly inflatable boats, which have limitations due to drawbacks such as easy aging and leakage. Detachable boats are generally speedboats made of hard materials such as aluminum alloy. The disassembly and assembly structure is relatively complicated, and the pontoon structure is difficult to store, which lacks convenience during use.
[0003] If a rigid boat is made into a foldable boat, the length of the boat will be limited due to structural limitations and portability considerations. Summary of the invention
[0004] The utility model aims to solve the above problems and provides an improved portable foldable boat.

[0012] In the stretched state, the telescopic hull is stretched into place and fixed to the second main hull by a first fastener, the telescopic floating body is stretched into place and fixed to the second floating body by a second fastener, and the telescopic hull and the telescopic floating body are fixedly connected by a third fastener.
[0013] In another improved portable foldable boat provided by the utility model, the first main hull and the telescopic hull are connected by a first hinge assembly, the second main hull is pulled out from the rear end of the telescopic hull, and the telescopic floating body is pulled out from the front end of the second floating body.
[0014] In the stretched state, the second main hull is stretched into place and fixed to the telescopic hull by the first fastener, and the telescopic floating body is stretched into place and fixedly connected to the fixing portion at the tail end of the first floating body.
[0015] In the stretched state, the telescopic floating body is stretched into place and fixed to the second floating body by a second fastener, and the telescopic hull and the telescopic floating body are fixedly connected by a third fastener.
[0016] In the above-mentioned improved portable folding boat, in the stretched state, the telescopic hull is sealed and connected to the second main hull, the inner hull of the telescopic hull and the inner hull of the second main hull are interconnected or are independent inner hulls through a partition plate; the telescopic floating body is sealed and connected to the second floating body, and the telescopic floating body and the second floating body can form two independently sealed cavities, or be connected to each other to form a sealed cavity.
[0017] Compared with the prior art, the advantages of the utility model are:
[0018] 1) The utility model realizes the storage of the three-section hull through a combination of telescoping and folding, which effectively extends the length of the foldable boat without occupying excess storage space, and can provide a larger use space while meeting portability.

Figure 3 The improved portable foldable boat is a schematic diagram of a folded state. The improved portable foldable boat comprises a main hull 1, wherein the main hull (1) comprises a first main hull (11) and a second main hull assembly (120) that are butt-jointed along the length direction, wherein the first main hull (11) and the second main hull assembly (120) are connected by a first hinge assembly (3) to achieve a folded storage state and an unfolded state of a butt-jointed structure; the second main hull assembly (120) comprises a second main hull (12) and a telescopic hull (13) sleeved inside the second main hull (12), wherein the telescopic hull (13) and the second main hull (12) are movably connected in a pull-out manner along the length direction to achieve a transition between a stretched state in which the telescopic hull (13) extends out of the second main hull (12) and a collapsed state in which the telescopic hull (13) and the second main hull (12) are sleeved. In the stretched state, the front end of the telescopic hull 13 is sealedly connected to the rear end of the second main hull 12 to prevent water leakage of the inner hull 10.
[0034] Specifically, the front end of the telescopic hull 13 has an end plate, and the edge of the end plate is sealed and connected to the rear end of the second main hull 12 through a sealing strip, so that the telescopic hull 13 and the second main hull 12 form two independent inner hulls 10.
[0035] Wherein, a first floating body 21 is provided on both sides of the first main hull 11, and a second floating body assembly (220) is provided on both sides of the second main hull 12.

That is, the second floating body assembly 220 can be folded upward from the use state of being in contact with the outer side wall of the hull to the floating body folded state in contact with the side wall of the inner hull 10 of the second main hull assembly 120. In the floating body folded state, the surface of the second floating body assembly 220 is lower than or flush with the ship's edge of the second main hull assembly 120.
