Description

Technical Field

[0001] This utility model relates to the field of inflatable boat technology, and in particular to an inflatable boat that is easy to transport. Background Technology

[0002] A speedboat is a type of fast boat that combines a rigid hull with inflatable sides. It combines the stability of a rigid hull with the buoyancy of inflatable sides, thus possessing good stability and seakeeping. Speedboats are commonly used in various situations such as maritime rescue, patrol, leisure and entertainment, and scientific research.

[0003] After the inflatable boat is used, it is towed to the shore by a trailer, or it can be transported by connecting its bow to other vehicles by using the support wheels at the stern of the boat to lift one end.

[0004] When transporting existing inflatable boats, the support wheels at the stern are needed to propel the boat across the ground. However, these support wheels are fixed to the stern and cannot be easily disassembled. This makes it inconvenient for users to remove the support wheels for different usage scenarios. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model provides an inflatable boat that is easy to transport.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: an inflatable boat that is easy to transport, comprising a hull, wherein two roller assemblies are provided at the stern end of the hull, and two mounting components are provided between each of the two roller assemblies and the hull;

[0009] The mounting assembly includes a fixed frame that is fixedly connected to the outer surface of the stern end of the hull, and two sliding blocks are slidably disposed inside the fixed frame, with two retraction springs fixedly connected between the two sliding blocks;

[0010] The roller assembly includes a fixed plate that engages with a sliding block. Two L-shaped blocks are fixedly connected to the side of the fixed plate away from the fixed frame. A rotating frame is movably connected between the two L-shaped blocks. A pulley is movably connected to the bottom end of the rotating frame. A movable plate is slidably arranged on the side of the L-shaped block away from the rotating frame. A tension spring is fixedly connected between the bottom end of the movable plate and the outer surface of the L-shaped block.

[0011] As a preferred embodiment of the inflatable boat that is easy to transport according to this utility model, the upper surface of the sliding block is movably connected to a threaded shaft, the top of the fixed frame is provided with a circular hole for moving with the threaded shaft, and the upper surface of the fixed frame is movably connected to a threaded sleeve that meshes with the threaded shaft.

[0012] As a preferred embodiment of the inflatable boat that is easy to transport according to this utility model, each of the two sliding blocks has a slot that cooperates with the fixing plate on one side adjacent to it.

[0013] As a preferred embodiment of the inflatable boat that is easy to transport according to this utility model, the sliding block is fixedly connected to both sides of the sliding block with limiting plates, and the fixed frame is provided with limiting grooves on both sides for the movement of the limiting plates.

[0015] As a preferred embodiment of the inflatable boat that is easy to transport according to this utility model, four abutment blocks are fixedly connected to the side of the fixed plate near the rotating frame.

[0016] (III) Beneficial Effects

[0017] This invention provides an inflatable boat that is easy to transport. It has the following advantages:

[0018] 1. By pressing down the fixing plate, the bottom end of the fixing plate causes the sliding block below to move downward, thereby causing the top of the fixing plate to separate from the slot inside the sliding block above. This allows the top of the fixing plate to be rotated outward to facilitate the removal of the pulley, separating the pulley from the hull. Furthermore, the height of the upper sliding block can be adjusted by rotating the threaded sleeve, thereby adjusting the height of the pulley.

[0019] 2. By lifting the movable plate, the limiting protrusion on the inner side of the movable plate separates from the through groove on the outer surface of the rotating frame, thus unlocking the rotating frame. After the rotating frame drives the pulley to rotate to the upward or downward position, the movable plate is reset by the action of the tension spring and the plug rod. This causes the limiting protrusion on the inner side of the movable plate to engage with the through groove on the outer surface of the rotating frame, thus restricting the rotating frame and preventing the rotating frame from driving the pulley to rotate. This facilitates the folding, storage, and use of the pulley. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Example 1

[0028] Reference Figure 1 , Figure 2 and Figure 4 This is the first embodiment of the present invention. This embodiment provides an inflatable boat that is easy to transport, including a hull 1. Two roller assemblies 2 are provided at the stern of the hull 1. Two mounting components 3 are provided between the two roller assemblies 2 and the hull 1. The mounting components 3 include a fixing frame 301 fixedly connected to the outer surface of the stern of the hull 1. Two sliding blocks 303 are slidably arranged inside the fixing frame 301. Two retraction springs 306 are fixedly connected between the two sliding blocks 303.

[0029] Specifically, a threaded shaft 304 is movably connected to the upper surface of the upper sliding block 303, and a circular hole for the threaded shaft 304 is provided at the top of the fixed frame 301. A threaded sleeve 305 that meshes with the threaded shaft 304 is movably connected to the upper surface of the fixed frame 301. A slot for cooperating with the fixed plate 202 is provided on the adjacent side of the two sliding blocks 303. Limiting plates 302 are fixedly connected to both sides of the sliding blocks 303, and limiting grooves for the movement of the limiting plates 302 are provided on both sides of the fixed frame 301.

[0030] Furthermore, by pressing down on the fixing plate 202, the bottom end of the fixing plate 202 causes the lower sliding block 303 to move downwards, thereby causing the top of the fixing plate 202 to separate from the slot inside the upper sliding block 303. This allows the top of the fixing plate 202 to rotate outwards, facilitating the removal of the fixing plate 202 and separating the pulley 206 from the hull 1. This facilitates the removal and installation of the pulley 206. Furthermore, the height of the upper sliding block 303 can be adjusted by rotating the threaded sleeve 305, thus adjusting the height of the pulley 206. When using the pulley 206 to transport the hull 1, the pulley 206 lifts the hull 1 via the upper sliding block 303. At the tail end, when the pulley 206 is not in use, the fixed plate 202 is supported by the lower sliding block 303 and the retraction spring 306. The retraction spring 306 can support the fixed plate 202 when the pulley 206 is retracted, thereby preventing the fixed plate 202 from causing the rotating frame 207 and the pulley 206 to fall when retracted. When adjusting the height of the upper sliding block 303, the two upper sliding blocks 303 are raised and lowered by rotating the two threaded sleeves 305 at the same time. The height error of the two sliding blocks 303 caused by manually adjusting the two threaded sleeves 305 is small and does not affect the slot of the fixed plate 202 inserted into the upper sliding block 303.

[0031] Example 2

[0032] Reference Figure 1 , Figure 2 and Figure 3 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The roller assembly 2 includes a fixed plate 202 that is engaged with the sliding block 303. Two L-shaped blocks 208 are fixedly connected to the side of the fixed plate 202 away from the fixed frame 301. A rotating frame 207 is movably connected between the two L-shaped blocks 208. A pulley 206 is movably connected to the bottom end of the rotating frame 207. A movable plate 203 is slidably arranged on the side of the L-shaped block 208 away from the rotating frame 207. A tension spring 204 is fixedly connected between the bottom end of the movable plate 203 and the outer surface of the L-shaped block 208.

[0033] Specifically, both ends of the top of the rotating frame 207 are provided with through slots, and the movable plate 203 is provided with a limiting protrusion on the side near the L-shaped block 208. Both ends of the top of the rotating frame 207 pass through the L-shaped block 208 and cooperate with the limiting protrusion on the outer surface of the movable plate 203. Two insert rods 205 are fixedly connected to the bottom of the movable plate 203. The L-shaped block 208 has through holes for the insert rods 205 to move inside. Four abutment blocks 201 are fixedly connected to the side of the fixed plate 202 near the rotating frame 207.

[0034] Furthermore, by lifting the movable plate 203, the limiting protrusion on the inner side of the movable plate 203 separates from the through groove on the outer surface of the rotating frame 207, thereby unlocking the rotating frame 207. Then, the rotating frame 207 drives the pulley 206 to rotate downward to a vertical position. At this time, the rotating frame 207 abuts against the two abutment blocks 201 below, thereby controlling the rotating frame 207 to keep the pulley 206 in a vertical position. Then, the movable plate 203 is released, and under the action of the tension spring 204 and the insertion rod 205, the movable plate 203 is reset, thereby bringing... The limiting protrusion on the inner side of the movable plate 203 engages with the through groove on the outer surface of the rotating frame 207, thereby restricting the rotating frame 207 and preventing the rotating frame 207 from driving the pulley 206 to rotate. This facilitates the folding, storage, and use of the pulley 206. When the rotating frame 207 drives the pulley 206 to the upward position, the rotating frame 207 abuts against the two upper abutment blocks 201, thus keeping the through groove on the outer surface of the rotating frame 207 in a vertical state. This allows the packaging movable plate 203 to smoothly drive the limiting protrusion into the through groove, thereby restricting the rotation of the rotating frame 207.

[0035] Working principle: When transporting the inflatable boat, the pulley 206 at the stern of the boat needs to be rotated downwards. By lifting the movable plate 203, the limiting protrusion on the inner side of the movable plate 203 separates from the through groove on the outer surface of the rotating frame 207, thereby unlocking the rotating frame 207. Then, the rotating frame 207 drives the pulley 206 to rotate downwards to a vertical position. At this time, the rotating frame 207 abuts against the two abutment blocks 201 below, thereby controlling the rotating frame 207 to keep the pulley 206 in a vertical position. Then, the movable plate 203 is released, and under the action of the tension spring 204 and the insertion rod 205, the movable plate 203 is reset, thereby causing the limiting protrusion on the inner side of the movable plate 203 to engage with the through groove on the outer surface of the rotating frame 207, thus restricting the rotating frame 207. To prevent the rotating frame 207 from driving the pulley 206 to rotate, and to facilitate the folding, storage, and use of the pulley 206, the installation of the pulley 206 can be selected according to the usage situation. When the pulley 206 needs to be removed, the bottom of the fixed plate 202 is pressed down, causing the lower sliding block 303 to move downward, thereby causing the top of the fixed plate 202 to separate from the slot inside the upper sliding block 303. This allows the top of the fixed plate 202 to be rotated outward, making it easier to remove the fixed plate 202 and separate the pulley 206 from the hull 1. This facilitates the removal and installation of the pulley 206. Furthermore, the height of the upper sliding block 303 can be adjusted by rotating the threaded sleeve 305, thereby adjusting the height of the pulley 206 and finally completing the transport of the assault boat.
