the limit assemblies 6 are respectively arranged at one end, far away from the wheels, of the two sides of the frame body 1; the limiting component 6 is hinged with the front end of the widening component 2 at the corresponding position.

In the embodiment, a first rotating shaft 10 is arranged at the inner end of the rotating plate 4, and a second rotating shaft 11 is arranged at the outer end of the rotating plate; the first rotating shaft 10 is hinged with the top wall and the bottom wall of the accommodating groove 7; the second rotating shaft 11 is hinged with the bearing rod 5, so that the rotating plate 4 can rotate conveniently.

In addition, the limiting assembly 6 comprises a fixed seat 12, a first connecting rod 13, a second connecting rod 14 and a locking sleeve 15; the fixed seat 12 is fixed on the side surface of the frame body 1; one end of the first connecting rod 13 is provided with a third rotating shaft 16 protruding upwards, and the third rotating shaft 16 is hinged with the front end of the bearing rod 5; the other end of the first connecting rod 13 is concavely provided with a chute 17, and the outer wall of the chute is provided with external threads; the outer wall of the second connecting rod 14 is provided with external threads, one end of the second connecting rod is hinged with the fixed seat 12, and the other end of the second connecting rod is positioned in the chute 17; the locking sleeve 15 is sleeved on the second connecting rod 14 and is in threaded fit with the second connecting rod 14; one end of the locking sleeve 15, which is close to the first connecting rod 13, is in threaded fit with the first connecting rod 13, and when the locking sleeve 15 is fixedly connected with the first connecting rod 13, the relative positions of the first connecting rod 13 and the second connecting rod 14 are not changed any more, and at the moment, the widening component 2 is limited and cannot shake, so that collision with the frame body 1 is avoided when a vehicle runs.

In actual use, the transversely widened trailer frame of the utility model can transversely widen the frame body 1 so as to carry a certain amount of goods with a width exceeding the width of the frame. In the initial state, the widening component 2 is in the folding state; rotating the locking sleeve 15, and moving the locking sleeve 15 to the end close to the fixed seat 12 along the direction of the second connecting rod 14 of the limiting assembly 6, wherein the locking sleeve 15 is separated from the second connecting rod 14; then the bearing rod 5 is stirred by external force, so that the bearing rod 5 moves towards the direction away from the frame body 1; because the third rotating shaft 16 on the first connecting rod 13 is hinged with the front end of the bearing rod 5, one end of the second connecting rod 14 is hinged with the fixed seat 12, when the position of the bearing rod 5 is changed, the second connecting rod 14 can move in the sliding groove 17 of the first connecting rod 13, and a plurality of rotating plates 4 can be synchronously rotated out; when the rotating plate 4 rotates to be perpendicular to the direction of the accommodating groove 7 of the fixed plate 3, the bearing rod 5 moves to the position of the widened maximum width of the frame, and then the locking sleeve 15 is rotated to move towards the first connecting rod 13 until the locking sleeve is fixedly connected with the first connecting rod 13. Because the locking sleeve 15 is in threaded fit with the outer walls of the first connecting rod 13 and the second connecting rod 14, after the locking sleeve 15 is fixedly connected with the first connecting rod 13, the second connecting rod 14 cannot move in the sliding groove 17 of the first connecting rod 13, so that the position of the bearing rod 5 can be fixed, and the bearing rod 5 is prevented from shaking in the transportation process.

When the goods with the width exceeding the width of the frame are unloaded, the widening assembly 2 needs to be retracted to the initial position; at this time, the locking sleeve 15 is rotated to separate from the first connecting rod 13, and then the bearing rod 5 is shifted to move towards the frame body 1 by external force until the top wall of the accommodating groove 7 of the fixed plate 3 enters into the avoiding groove I8 of the bearing rod 5, the first rotating shaft 10 at the inner end of the rotating plate 4 enters into the avoiding groove II 9 at the corresponding position, and at this time, one side of the bearing rod 5, which is close to the frame body 1, is tightly attached to the side surface of the frame body 1. Finally, the locking sleeve 15 is rotated to be connected and fixed with the first connecting rod 13 again, the widening component 2 is folded, meanwhile, the folded widening component 2 can be prevented from shaking when a vehicle runs, and damage caused by collision between the widening component 2 and the frame body 1 is effectively prevented.

The trailer frame capable of being transversely widened not only can solve the problem that a plurality of rotating plates 4 cannot be screwed out synchronously, but also can prevent the widening component 2 from colliding with the side edge of the frame body 1 in the driving process by arranging the limiting device at the front end of the frame body 1, effectively reduces the transportation risk, is quite practical and has good market application prospect.
