Boat trailer with high weather resistance

The invention discloses a boat trailer with high weather resistance. The boat trailer with the high weather resistance mainly comprises a frame and wheels, wherein the frame is formed by side frames; the side frames are positioned on two sides of a vehicle bottom plate; the sections of the side frames are shaped like I; the wheels are symmetrically arranged on two sides of the frame; one end, corresponding to a boat bow, of the frame is a front end; the front end is shaped like V; and the opposite end of the front end is a tail end. The boat trailer with the high weather resistance further comprises a supporting frame, a bearing roller device and a guiding roller device, wherein the supporting frame is connected between the side frames; the bearing roller device and the guiding roller device are both arranged on the supporting frame; the supporting frame is a hollow structure with a square section; a vertical reinforcing rib is also arranged in the supporting frame; the vertical reinforcing rib divides the interior of the supporting frame into two accommodating chambers; two ends of the supporting frame are higher than the middle part of the supporting frame; and the supporting frame and the side frames are all made of aluminum materials. The manufacturing materials cannot form iron pollution in the forming process and aluminum can form an oxidation film for preventing metal corrosion in the moist air; therefore, the service life of the boat trailer can be effectively prolonged; and moreover, as the mass of the aluminum is light, the boat trailer is convenient to transport and use.
