Description

Technical Field

[0001] The utility model relates to the technical field of boat towing frames, in particular to a glass fiber reinforced plastic boat towing frame. Background Art

[0002] A boat trolley is a structural device used to support and move boats, primarily for transport and storage. Typically constructed of steel, aluminum, or other high-strength materials, it is designed to bear the weight of the boat and provide stable support, protecting it from damage during movement. Boat trolleys are widely used for boat maintenance, repair, and transfer, serving as a crucial aid in managing water transportation equipment.

[0003] When transporting fiberglass hulls, trailers are often required due to their large size and smooth surface. Existing fiberglass boat towing racks typically use welded, integrated boat placement components to support the boat bottom. While this structure offers high integrity and stability, its fixed design lacks flexibility for adjusting to hulls of varying sizes and shapes. This is particularly true during transportation, as the boat bottom is typically spindle-shaped and angled. This makes it difficult to effectively support both sides of the bottom based on the spindle-shaped angles of the hull, making it prone to side-to-side swaying during travel. This increases the risk of collision and poses a potential safety hazard.

[0004] Therefore, an improved towing frame design is needed that can flexibly adjust the angle of the boat placement component 2 to better adapt to the bottom contours of hulls of different shapes, thereby improving stability and safety during transportation. Utility Model Content

[0005] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the present invention to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0006] Therefore, the purpose of the present utility model is to provide a fiberglass boat towing frame, which can solve the problem that the existing fiberglass boat towing frame lacks adjustment flexibility due to its welded one-piece structure and cannot effectively support the bottom of hulls of different sizes and spindle angles, resulting in the hull shaking from side to side during transportation and increased collision risk.

[0007] In order to solve the above technical problems, the utility model provides a fiberglass boat towing frame, which adopts the following technical solutions: comprising a metal bracket, a boat placement assembly is installed on the top of the metal bracket, a direction adjuster is installed on one side of the metal bracket, and an auxiliary tractor is also provided on the top of the metal bracket near the direction adjuster. The boat placement assembly includes a supporting bottom bracket, and a plurality of groups of limit top brackets are installed in the middle of the supporting bottom bracket;

[0008] The limiting top support includes a connecting seat, and guide rollers are rotatably connected on both sides of the connecting seat. A first hinged seat is installed at both ends of the connecting seat, and a support arm rod is hinged inside the first hinged seat. A first hinge plate is provided at the bottom of the end of the support arm rod close to the first hinged seat, and the end of the support arm rod away from the first hinged seat is also rotatably connected to a guide wheel.

[0009] Optionally, the supporting base includes two groups of supporting beams, and several groups of fixed beams are equidistantly distributed in the middle of the two groups of supporting beams, one group of fixed beams is provided with second hinge plates on both sides of the bottom, and several groups of fixed beams are also provided with second hinge seats at both ends of the top.

[0010] Optionally, the second hinge seat matches the first hinge plate structure, and the second hinge seat and the first hinge plate are hingedly matched.

[0011] Optionally, a third hinge seat is installed on both sides of the tail of the metal bracket, and the third hinge seat matches the second hinge plate structure, and the third hinge seat and the second hinge plate are hinged together.

[0012] Optionally, two sets of spiral adjusters are provided on both sides of the interior of the metal bracket, and the top end of the spiral adjuster is also hingedly connected to a push-up support plate, which matches the support arm structure, and there is a transition fit between the push-up support plate and the support arm.

[0013] Optionally, the auxiliary traction device includes a mounting frame, a rope support guide frame is connected to the middle of the mounting frame, and a traction winch is also provided on the top of the mounting frame.

[0014] In summary, the present invention has at least one of the following beneficial effects:

[0015] 1. This solution uses a boat placement assembly installed on the top of the metal bracket. The boat placement assembly is mainly composed of a supporting bottom bracket and a limiting top bracket. The limiting top bracket includes a connecting seat, a guide roller, a first hinged seat, a support arm, a first hinged plate and a guide wheel. The guide rollers on both sides of the connecting seat rotate to support it, which not only provides upward support for the bottom of the hull, but also enhances the sliding properties of the bottom of the hull on the boat placement assembly, thereby facilitating the auxiliary tractor to pull the hull to a suitable position and fix it on the top of the assembly.

[0016] 2. This solution uses a support arm rod hingedly connected at both ends of the connecting seat. The support arm rod is hingedly matched between the second hinge seat and the first hinge plate through a structural design, so that multiple limit top supports are movably connected to the top of the support bottom support. When the limit top support is used in combination with the spiral adjuster, the angle between the support arm rod and the connecting seat can be flexibly adjusted according to the shuttle-shaped angle of the bottom of the hull, so that the guide wheel installed at the end of the support arm rod can always maintain a supporting and fitting state with the bottom of the shuttle-shaped hull.

[0017] 3. From the above, it can be seen that the fiberglass boat towing rack designed in this scheme can flexibly adjust the support angle of the boat placement component according to the shuttle angle of the bottom of the different hulls, which can effectively prevent the hull from shaking during transportation due to insufficient contact between the bottom and the boat placement component, or a large gap in the upward support, thereby improving the flexibility and practicality of the equipment in the field of boat towing rack technology.
