Embodiment Construction
[0023] The present invention will be further described below in conjunction with the embodiment represented by accompanying drawing:
[0024] Such as Figure 1-4 As shown, this embodiment discloses a dual-purpose trailer in standing and lying positions, which mainly includes a loading floor, a frame and wheels 40. The frame structure is simple, the loading capacity is large, and it is light and stable. The loading floor includes a main board 11 and an extension board 12. The main board 11 and the extension board 12 are hinged. The setting of the extension board 12 can extend the loading bottom board according to the loading requirements; alloy with good properties.
[0025] The vehicle frame includes a draw bar 21 and a vehicle frame, and the support frame 22 includes two symmetrically arranged arc bars 221, and the lower ends of the two arc bars 221 are connected with the loading floor through a folding mechanism 30 to facilitate storage; the two arc bars 221 The gradual up...

The invention discloses a dual-purpose trailer for a standing posture and a lying posture, which comprises a loading bottom plate and a frame, the frame comprises a traction rod and a supporting frame, the supporting frame comprises two symmetrically-arranged arc-shaped rods, and the lower ends of the two arc-shaped rods are connected with the loading bottom plate through a folding mechanism and gradually rise and extend to form an upward arch. The two arc-shaped rods gradually draw close in the upward extending process and are connected at the top ends; the traction rod is arranged at the upper end of the supporting frame, a force application end is formed at the upper end of the traction rod, and the force application end bends and extends in the direction away from the loading bottom plate. The dual-purpose trailer is simple and stable in overall structure, easy to store and convenient to use; by optimizing the structure of the trailer frame, the trailer can meet standing traction and prone traction at the same time, and the applicability is higher; the supporting frame is combined with ergonomics and adopts the optimal size and radian, traction can be achieved in the normal advancing process of a traction person, and labor saving and convenience are achieved.
Description
technical field [0001] The invention belongs to the technical field of trailers, and in particular relates to a dual-purpose trailer in standing and lying positions. Background technique [0002] Trailers are widely used in different scenarios. When individuals need to move people or carry goods, regardless of the posture of moving or carrying, the physiological quality of the human body cannot undertake long-term operations, and it is very easy to cause damage to the functions of human organs. strained, so a tow truck is required. Most of the existing trailers can only be towed in a standing position, and cannot be towed in a prone position when the space is narrow or in special use scenarios, which limits the functionality of the trailer, cannot adapt to different usage scenarios, and has a poor user experience. Contents of the invention [0003] The present invention aims at the problem that the trailer in the prior art can only be towed in a standing position, but can...
