Embodiment Construction

[0037] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] See Figure 1-6 , The present invention provides a trailer that does not become taller when folded, including fixed standpipes arranged at the front and rear ends of the trailer, and front and rear folding assemblies connected to the fixed standpipes, side folding assemblies, bottom folding assemblies, and handle assemblies.

[0039] Specifically, two fixed standpipes 1 are respectively arranged at the front and rear ends of the trailer, and a roller 28 is installed at the lower end of any fixed standpipe 1 , and the roller 28 is installed on the lower end of the fixed standpipe 1 through a wheel fork 29 .

[0040] A corner fixing part 2 is installed on the upper end of any fixed vertical pipe 1 , and a foot fixing part 3 is installed near the lower end of any fixed vertical pipe 1 . A first linkage sliding sleev...

Abstract

The invention provides a trailer capable of not being heightened after being folded. The trailer capable of not being heightened after being folded comprises fixed vertical pipes arranged at the frontand rear ends of the trailer, front and rear surface folding assemblies, side surface folding assemblies, bottom folding assemblies and a handle assembly, wherein the front and rear surface folding assemblies, the side surface folding assemblies, the bottom folding assemblies and the handle assembly are connected with the fixed vertical pipes. The trailer is folded by arranging the front and rearsurface folding assemblies, the side surface folding assemblies and the bottom folding assemblies, the height of the trailer cannot be changed after the trailer is folded, so that the height after the trailer is folded and the height during using are ensured to be same, and the purpose that a volume after the trailer being folded is less than a volume of an existing trailer can be realized. A telescopic assembly is arranged on the handle assembly to perform telescopic folding on the handle assembly when the trailer is not used, space occupation is reduced, and practicality and convenience areachieved; and meanwhile, reset torsion springs are arranged on the handle assembly, and the purpose that a handle automatically resets under an unused state can be realized.

Description

technical field [0001] The invention relates to the technical field of trailers, in particular to a trailer that cannot become higher when folded. Background technique [0002] In daily life and production, it is often necessary to carry luggage or articles, and trailer tools are often used in the process of carrying. Trailers are widely used in moving things because of their convenient driving and time-saving and labor-saving characteristics. Many trailers now use a flat plate with wheels installed under the flat plate for consignment. This kind of trailer cannot be folded. When not in use Takes up a lot of space. [0003] There are some trailers that can be folded, but they have the following disadvantages: [0004] (1) The trailer capacity is small, the height increases after folding, and the volume after folding is large; [0005] (2) The handle of the trailer cannot be reset automatically, which is inconvenient to use. Contents of the invention [0006] The object...
