In one embodiment, the frame body 31 is rectangular in shape. It is understood that the shape of the frame body 31 is not limited thereto, and the shape of the frame body 31 may also be circular as in other embodiments.

Referring to fig. 2 and 3, the connecting member 32 includes a mounting block 321, a mounting seat 322, a plug rod 323, a spring 324, and a limiting post 325. The mounting block 321 is disposed on the frame body 31. The mounting seat 322 is fixed on the mounting block 321, and a through hole 3221 is formed in the mounting seat 322. The insertion rod 323 is located in the through hole 3221. The spring 324 is disposed on the insertion rod 323 and located in the mounting seat 322, and two ends of the spring 324 are used for abutting against the mounting seat 322 and the insertion rod 323. The limiting column 325 is disposed on the mounting seat 322.

The mounting block 321 is fixed to the frame body 31 at one end, and extends downward from the frame body 31 by a predetermined length to fix and support the mounting seat 322. The fixing manner of the mounting block 321 and the frame body 31 includes, but is not limited to, welding, integral molding, and the like.

The mounting seat 322 is fixed on the mounting block 321, and is used for supporting the insertion rod 323 and the spring 324. The fixing manner of the mounting seat 322 includes, but is not limited to, screw connection, welding, and integral molding.

The fastening member 412 extends from one end of the bracket body 411 to a direction away from the bracket body 411 by a predetermined length. The fastening member 412 is connected to the dragging member 50 to transmit the driving force of the dragging member 50 to the bracket body 411. The insertion rod 323 extends into the fastening member 412 to fix the frame body 31 and the bracket body 411, so that when the axle 10 rotates, the bracket body 411 drives the frame body 31 to rotate. In one embodiment, the fastener 412 is a sheet-like plate, but is obviously not limited thereto, and as in other embodiments, the fastener 412 may also be a rod.

The fastening member 412 is provided with an insertion hole 4121, and the insertion rod 323 can extend into the insertion hole 4121 to fix the bracket body 411 and the frame body 31.

The fastening member 412 is further provided with a first hinge hole 4122 and a first fixing hole 4123. The first hinge hole 4122 and the first fixing hole 4123 are fitted to the dragging member 50.

The two ends of the rotating member 42 are fixed to the frame body 31 and the bracket body 411, and the bracket body 411 can rotate relative to the rotating member 42. In one embodiment, the rotating member 42 is a circular turntable, but obviously is not limited thereto, and the rotating member 42 may also be a rotating shaft in other embodiments.

Referring to fig. 1, the trailer 100 further includes a trailer 50, and one end of the trailer 50 is connected to the fastening member 412, and the other end is connected to another fastening member 412, so as to hang the trailer 100 in multiple sections. In one embodiment, the dragging member 50 has a rod shape. It will be appreciated that the type of the drag 50 is not limited thereto, and that the drag 50 may also be cylindrical, as in other embodiments.

Example two

Referring to fig. 4, the trailer 100 of the second embodiment is substantially the same as that of the first embodiment, except that the rotating assembly 40 is a rotating bridge 80. The number of the rotating bridges 80 is two, and the two rotating bridges 80 are fixed on the frame body 31.

Referring to fig. 1, 2 and 3, in operation, when the trailer 100 needs to be pulled in a specific direction, the insertion rod 323 at the end to be pulled is pulled out, and the insertion rod 323 is disengaged from the insertion hole 4121. The inserting rod 323 is rotated until the stopping post 3231 abuts against the limiting post 325. At the other end of the trailer 100, the insertion rod 323 is rotated, and under the action of the spring 324, the insertion rod 323 extends into the insertion hole 4121. The fixing member 70 is inserted into the first fixing hole 4123 and the second fixing hole 52 at the end to be dragged. At this time, the frame body 31 and the bracket body 411 at the end to be dragged are rotatably connected, the dragging part 50 and the bracket 41 are fixedly connected, and the dragging part 50 is dragged to drive the trailer 100 to move and turn. At the other end of the trailer 100, the frame body 31 is fixed to the bracket 41, and the dragging member 51 is hinged to the bracket body 411, so that the next trailer 100 can be connected through the dragging member 50, and the next trailer 100 is driven to move and rotate.

When the dragging direction needs to be changed, the insertion rod 323 at one end of the trailer 100 is inserted into the insertion hole 4121, and the fixing member 71 is pulled out. The insertion rod 323 and the insertion hole 4121 at the other end of the trailer 100 are separated, and the fixing member 70 is inserted into the first fixing hole 4123 and the second fixing hole 52, so that the dragging direction can be changed.

The trailer 100 provided above is realized by fixing the two rotating assemblies 41 on the axle 10, and enabling the rotating assembly 41 located at the front side in the direction to rotate relative to the frame 31, and enabling the rotating assembly 40 located at the rear side in the direction to be fixedly connected with the frame 31, so that the wheel 20 located at the front side in the direction can rotate along with the direction, and the wheel 20 located at the rear side in the direction and the frame 30 are kept fixed in position, thereby realizing good tracking performance even if the trailer 100 has multiple sections. The two-way dragging of the trailer 100 is realized by adjusting the connection relationship between the front and rear side rotating assemblies 40 and the frame 31.

In addition, those skilled in the art should recognize that the foregoing embodiments are illustrative only, and not limiting, and that appropriate changes and modifications to the foregoing embodiments may be made within the spirit and scope of the present disclosure.
