Problems solved by technology

[0003] For example, the invention patent with the authorized notification number CN203600915U discloses a combined trailer arm, which includes a main body of the arm and a main body of a trailer ball. The main body of the trailer ball is arranged at the end of the main body of the trailer arm. The main body of the trailer ball includes a trailer ball and a nut. The trailer ball is movably installed on the curved arm. By installing this trailer arm, the two vehicles can move synchronously, but there are the following problems: 1. The curved arm passes through the standard square pipe Welding and other methods are fixed as a whole. When the trailer arm is used for a long time or the force of the trailer ball is too large, it is easy to break between the curved arm and the standard square tube, which makes the entire trailer arm unable to continue to be used, resulting in the use of the trailer arm. Shorter service life; 2. The trailer arm and the trailer ball are in a fixed state, which cannot be adjusted for different heights of the motor vehicle chassis, resulting in scattered force during use, more force loss, and easy damaged

Abstract

The invention provides an adjustable trailer device and belongs to the technical field of motor vehicle accessories. The adjustable trailer device solves the technical problems that in an existing trailer arm, trailer balls are prone to being broken and the trailer arm is prone to being damaged. According to the technical scheme, the adjustable trailer device comprises a main arm, an adjusting ram and a trailer ball assembly, wherein the main arm is fixedly connected with a motor vehicle; the adjusting arm is vertically and fixedly connected with the end of the main arm; the trailer ball assembly is used for being connected with another motor vehicle; the trailer ball assembly makes contact with the adjusting arm and can vertically move on the adjusting arm, and when the trailer ball assembly moves to the designated position, the trailer ball assembly can be fixed to the adjusting arm. The adjustable trailer device has the beneficial effects that the trailer ball assembly is movably connected with the main arm, so that the situation that the trailer ball assembly is broken is avoided, the trailer ball assembly is longer in service life and can be fixed to positions, with different heights, of the adjusting arm, the stress of the trailer ball assembly is more concentrated, the loss of force is less, and the damage rate of the main arm is smaller.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle accessories, and relates to a trailer device, in particular to an adjustable trailer device. Background technique [0002] The trailer arm is a pendant installed on the rear chassis of the motor vehicle and its connection function is to connect the trailer or the motor vehicle that cannot be driven. In daily life, on the one hand, it is to carry more items. Emergency rescue use. [0003] For example, the invention patent with the authorized notification number CN203600915U discloses a combined trailer arm, which includes a main body of the arm and a main body of a trailer ball. The main body of the trailer ball is arranged at the end of the main body of the trailer arm. The main body of the trailer ball includes a trailer ball and a nut.
