DETAILED DESCRIPTION
[0021] The specific implementation of the utility model is further described below in combination with the drawings and examples. The following examples are only used to more clearly illustrate the technical scheme of the utility model, and cannot limit the protection scope of the utility model.
[0022] As Figures 1-4As shown, a luggage with expansion function, comprising a first box body 1, a second box body 2 hinged to the first box body 1, a zipper 3 arranged between the first box body 1 and the second box body 2, four universal wheels 4 arranged at the bottom of the first box body 1 and the second box body 2, a pull rod 5 arranged on the first box body 1, and at least one expansion device arranged on the second box body 2 to facilitate the user to quickly increase the storage space.
[0023] In order to facilitate the expansion of the storage space, the expansion device comprises a slot 6 opened on the second box body 2, an expansion cover 7 slidably arranged on the slot 6 through a sliding guide device, and a telescopic protection device arranged between the expansion cover 7 and the second box body 2.
[0024] In order to facilitate the control of the movement of the expansion cover 7, the sliding guide device comprises an L-shaped fixed seat 8 arranged on one side of the second box body 2 close to the zipper 3, a rotating column 9 rotatably arranged on the L-shaped fixed seat 8 and corresponding to one corner of the slot 6, a threaded hole 10 opened on the rotating column 9, a threaded column 11 arranged on the expansion cover 7 and matched with the threaded hole 10, and three groups of guide devices arranged between the expansion cover 7 and the second box body 2.
[0025] In order to improve the stability of the expansion cover 7 when it is opened, the guide device comprises a guide sleeve 12 arranged in another corner of the slot 6 in the second box body 2, a guide column 13 arranged on the expansion cover 7, and a deviation prevention device arranged between the guide sleeve 12 and the guide column 13, wherein the deviation prevention device comprises a deviation prevention groove 14 arranged in the guide sleeve 12 and a deviation prevention block 15 arranged on the guide column 13.
[0026] In order to improve the stability of the expansion cover 7 when it is opened, a flush device is further arranged between the guide sleeve 12 and the guide column 13, wherein the flush device comprises a limiting ring table 16 arranged at the bottom of the guide sleeve 12 and a spring (not shown in the figure) arranged in the guide sleeve 12, one end of the spring abutting against one end of the limiting ring table 16 and the other end of the spring abutting against the guide column 13.
