Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle equipment, and relates to a device for widening the widths of both sides of a lightweight vehicle carriage. Background Art

[0002] In the prior art, the width of a carriage is generally fixed. When loading and transporting relatively wide goods, due to the fixed width of the carriage, the relatively wide goods cannot be placed in the carriage, which greatly reduces the usability.

[0003] Widening the carriage is of great significance in the actual use of vehicle equipment. Widening the carriage not only increases the transportation capacity, but also greatly facilitates the loading of large objects and improves the economy. It is an effective means to solve the transportation problem.

[0004] Currently, the common way to widen a carriage is to install a telescopic device made of steel on both sides of the carriage, which is pushed by an electric push rod, a hydraulic cylinder, etc. to achieve the widening of the carriage. However, this method has a complex and heavy structure, poor flexibility, and requires major modifications, with a large modification difficulty and high cost. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a device for widening the widths of both sides of a lightweight vehicle carriage, so as to solve the technical problems in the prior art that the structure for widening the carriage is complex and heavy, with poor flexibility and large modification difficulty.
