Description

Technical Field

[0001] The utility model belongs to the technical field of detachable carriage vehicles, and particularly relates to a locking device for a detachable carriage vehicle. Background Art

[0002] A detachable car is a car designed with a detachable car body. The detachable feature allows the car body to be separated from the car body, so that one set of car bodies can be used for multiple sets of cars, which can greatly improve the utilization rate of the car. The existing locking device of a detachable car can meet the flexible fixation of the car body and the car body, and can enable the user to conveniently move the car body to the top of the car body or remove the car body from the top of the car body through the supporting structure without the need for lifting equipment. However, due to the lack of a positioning guide structure, the user cannot quickly and conveniently confirm whether the car body has been accurately moved to the top of the car body. The user needs to spend more time to adjust the position of the car body, which will cause the user to spend more time when connecting the car body to the car body, thus affecting the assembly efficiency of the car body and the car body.

[0003] For example, the utility model with the announcement number CN 218751080 U discloses a positioning and locking device for a car with a detachable carriage. In the technical solution of this patent, although the support structure enables the user to conveniently move the carriage to the top of the car body, or remove the carriage from the top of the car body, since there is no guide positioning structure between the carriage and the car body, when the user moves the car body to the bottom of the carriage, the positioning alignment between the car body and the carriage cannot be quickly achieved, and the user needs to spend more time to adjust the position of the car body, which brings great inconvenience to people's use and leads to low installation efficiency of the carriage and the car body.
