[0015] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0016] The utility model proposes a combined trailer, which includes two carriers 1, rollers 11 are installed at the four corners of the bottom of the two carriers 1, and the tops of the two carriers 1 are fixedly provided with fixing frames 12, and the bottoms of the two carriers 1 are provided with fixing components 2, and the fixing components 2 include two plug-in plates 21, and the two plug-in plates 21 are correspondingly arranged at the bottom of one of the carriers 1, and the outer wall of the plug-in plate 21 is slidably provided with a concave plate 22, and the two concave plates 22 are fixed to one side of the bottom of the other carrier 1, and the concave plates 22 are fixed to the bottom of the other carrier 1. The bottom of 22 is threadedly connected with a knob screw 23, and the top of the knob screw 23 is inserted into the groove of the plug plate 21. The plug plate 21 is inserted into the corresponding inner cavity of the concave plate 22, and then the knob screw 23 is tightened so that the knob screw 23 can press the groove inside the plug plate 21 tightly, thereby fixing the plug plate 21. At this time, the two carrier plates 1 can fit each other, thereby realizing the rapid assembly of the two trailers. One end of the plug plate 21 inserted into the concave plate 22 is processed with a rounded corner to facilitate the connection and correspondence between the plug plate 21 and the concave plate 22.

[0017] Specifically, the plug board 21 is arranged in a convex shape, and the width of one end of the plug board 21 inserted into the concave plate 22 is smaller than that of the other end. The outer wall of the narrower end of the plug board 21 is slidably connected with a fixing sleeve 24, and the fixing sleeve 24 is fixedly arranged at the bottom of one of the carrier plates 1. By setting the fixing sleeve 24, the plug board 21 can be hidden, thereby facilitating its separate use.

[0018] Specifically, a second magnet 26 is fixedly provided at the bottom of one of the carrier plates 1 corresponding to the plug board 21. The second magnet 26 can be magnetically connected to the corresponding plug board 21. Its design purpose is to enable the plug board 21 to be stably hidden at the bottom of the carrier plate 1. The second magnet 26 is designed in an L shape to support one end of the plug board 21.

[0019] Specifically, a first magnet 25 is fixedly provided on one side of the fixing sleeve 24 away from the recessed plate 22. The first magnet 25 can be magnetically connected to the corresponding plug plate 21. The design of the first magnet 25 can prevent the plug plate 21 from retracting when the plug plate 21 enters the inner cavity of the recessed plate 22, thereby further facilitating the connection between the plug plate 21 and the recessed plate 22.

[0020] Specifically, a suspension bracket 13 is fixedly provided at one end of each of the two carrier plates 1. The two suspension brackets 13 are designed in an upper and lower position, and the sockets of the two suspension brackets 13 are correspondingly arranged. This design can facilitate the front of the vehicle to drive the combined trailer to move.

[0021] Working principle: When using the combined trailer, the user can manually push the plug plate 21 at the bottom of one of the carrier plates 1 to separate it from the second magnet 26 and magnetically connect it to the first magnet 25. At this time, the plug plate 21 is exposed, and the plug plate 21 is inserted into the corresponding inner cavity of the concave plate 22. Then, the knob screw 23 is tightened so that the knob screw 23 can press the groove inside the plug plate 21 tightly, thereby fixing the plug plate 21. At this time, the two carrier plates 1 can fit each other, thereby realizing the rapid assembly of the two trailers. After the assembly is completed, the items to be transported can be fixed inside the fixing frame 12. After the two carrier plates 1 are connected correspondingly, the sockets of the two suspension frames 13 can also be connected to the tail of the front of the vehicle. At this time, the front of the vehicle can be driven to drive the trailer and the items to move. This connection method can realize the rapid assembly of the trailer and facilitate the mutual correspondence of the two carrier plates 1.
