Description

Technical Field

[0001] This utility model relates to the field of traction technology, and in particular to a towing device for a trailer caravan. Background Technology

[0002] A towable caravan is a mobile living space that can be towed by a car, providing travelers with a convenient and flexible accommodation solution. Compared to motorhomes, towable caravans have advantages such as relatively lower prices, lower maintenance costs, and easier parking.

[0003] However, in the existing technology, when the RV towing device is in use, the tow bar will turn with the vehicle, causing the towed RV to sway from side to side. The poor stability of the tow bar will cause the towed RV to shake, thereby reducing the stability of the towed RV and reducing the service life of the tow bar. Moreover, most tow bars are of fixed size, which makes it inconvenient to adjust their length as needed. Too long or too many tow bars will affect the stability of the towed RV. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where, when using a motorhome towing device, the tow bar causes the towed motorhome to sway left and right as the vehicle turns, resulting in poor stability and swaying of the towed motorhome. This reduces the stability of the towed motorhome and shortens the service life of the tow bar. Furthermore, most tow bars have fixed dimensions, making it inconvenient to adjust their length as needed. Excessively long or numerous tow bars can also affect the stability of the towed motorhome.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a towing device for a trailer caravan, comprising: a U-shaped connecting plate and a towing rod, and further comprising:
