Description

Technical Field

[0001] This utility model relates to the field of trailer hitch technology, specifically a retractable double-headed trailer hitch. Background Technology

[0002] A tow hook is a tool used to tow a vehicle when it breaks down or suffers other malfunctions. The tow hook on a regular sedan is usually a tow ring, which has threads on the front and rear bumpers. The tow ring needs to be screwed onto these threads before towing can be performed.

[0003] As for sightseeing vehicles, the existing tow hooks are all single tow hooks that are fixedly connected to the chassis. The hook head is directly exposed outside the vehicle body, which is unsightly and poses a collision threat to tourists. In addition, they cannot be adapted to tow hooks that are too large or too small, making them less practical.

[0004] To address this, we designed and developed a retractable double-headed tow hook for use on sightseeing vehicles. This tow hook features a double-headed design, allowing the hook head to be hidden inside the vehicle's exterior panel when not in use, or it can be removed directly, improving the overall aesthetics of the sightseeing vehicle and preventing tourists from easily bumping into the hook head. At the same time, the double-headed design allows the hook head to adapt to different sized tow hooks, preventing the tow hook from easily separating from the tow hook and ensuring stability during towing.

[0008] As a further preferred embodiment of this utility model: a fixed plate is fixedly installed at the end of the telescopic arm beam away from the fixed arm beam. Two corresponding hook upper plates and hook lower plates are fixedly installed on the fixed plate. A hook partition plate is also fixedly installed on the fixed plate between the hook upper plate and the hook lower plate. The hook partition plate divides the hook upper plate and the hook lower plate into an upper hook body and a lower hook body. Corresponding hook pin holes are opened on the hook upper plate, the hook lower plate and the hook partition plate. Hook pins for connecting with the traction hook can be inserted into two adjacent hook pin holes.

[0009] As a further preferred embodiment of this utility model: the limiting component includes multiple positioning holes formed on the fixed arm beam and the telescopic arm beam, the positioning holes penetrating the fixed arm beam and the telescopic arm beam, and positioning pins inserted into the positioning holes.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This dual-headed trailer hook features a scientifically designed and reasonable configuration, allowing for easy extension, retraction, and disassembly of the trailer hook on the vehicle body. When not in use, the telescopic arm can be concealed within the fixed arm through its cooperation with the telescopic arm, keeping the hook head hidden inside the vehicle body panel. Alternatively, the telescopic arm can be directly removed from the fixed arm, improving the overall aesthetics of the vehicle body and preventing the exposed hook head from posing a risk of collision to people around the vehicle. Furthermore, the design employs two dual-headed hooks of different sizes, allowing for the selection of either the upper or lower hook body to connect with the tow hook, ensuring a stable connection between the tow hook and trailer hook. This avoids the problems of the tow hook being too large to connect or too small to easily detach. The design is scientifically sound, with a simple and innovative structure, and strong practicality.
