DETAILED DESCRIPTION

[0020] The embodiments of the present application will be described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0021] Please refer to Figures 1-4The utility model relates to a trailer structure with unhooking brake function, including trailer frame 100, rear wheel assembly 200 is installed to the bottom rear end of trailer frame 100, rotating disc 300 is installed to the bottom front end of trailer frame 100, rotating frame 400 is installed on rotating disc 300, front wheel assembly 500 is installed to the bottom of rotating frame 400, pull rod 700 is rotatably connected through shaft pin 600 to the front end of rotating frame 400, brake support 800 is installed to the bottom of pull rod 700, brake pad 810 is fixedly installed to both ends of brake support 800, and the brake pad 810 corresponds the wheel two 520 of front wheel assembly 500, specifically, when pull rod 700 is separated from the tractor, the one end of pull rod 700 away from trailer frame 100 is not supported, and under the influence of gravity, rotates downward, simultaneously drives brake support 800 to rotate, and the brake pad 810 on brake support 800 contacts wheel two 520 and prevents wheel two 520 from rotating.
