DETAILED DESCRIPTION

[0026] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp. Example

[0027] Reference Figure 1 , Figure 2 The present embodiment provides a box structure that is easy to open, including a cover plate 2 and a box body 1. The upper end of the box body 1 has an opening, and the cover plate 2 is used to cover the opening. A support plate for supporting the cover plate 2 is provided on the inner side wall of the box body 1.

[0028] A through slot for the cover plate 2 to pass through is provided at the rear side of the upper end of the box body 1 corresponding to the position of the cover plate 2, and a slide slot 111 is provided on the left and right sides of the through slot, and the slide slot 111 extends along the front-back direction of the box body 1. A guide plate 5 is slidably provided in the slide slot 111, and a limiting groove 112 is provided in the slide slot 111. A first limiting block 52 cooperating with the limiting groove 112 is provided on the guide plate 5, and the first limiting block 52 cooperates with the limiting groove 112 to limit the front-back sliding distance of the guide plate 5. Through the above structure, the front-back sliding connection between the guide plate 5 and the box body 1 is realized.

[0029] Reference Figure 3-Figure 5 , it can be seen that the two guide plates 5 are respectively located on the left and right sides of the cover plate 2, and a connecting shaft 51 is provided on the side facing the cover plate 2; the connecting shaft 51 extends into the guide groove 21 on the corresponding side, so that the cover plate 2 can slide and rotate relative to the guide plate 5. When the guide plate 5 slides backward to a preset position and continues to slide, the connecting shaft 51 gradually extends from the rear side of the box body 1. In this way, after the connecting shaft 51 extends out of the box body 1, it is equivalent to moving the rotation center of the cover plate 2 outside the box body 1, so that the cover plate 2 can be conveniently rotated directly without interference from the side wall of the box body 1.

[0030] The left and right sides of the cover plate 2 are both provided with guide grooves 21 extending forward and backward; the connecting shaft 51 extends into the guide groove 21 on the corresponding side, so that the cover plate 2 can slide and rotate relative to the guide plate 5. The rear end of the guide groove 21 forms a positioning groove 24, which is formed by the protrusions 23 on the side walls of the two guide grooves 21 and the side walls of the guide groove 21. The slot width of the positioning groove 24 (i.e., the spacing between the protrusions 23) is smaller than the diameter of the connecting shaft 51. In the initial state, the connecting shaft 51 is located in the positioning groove 24. When the cover plate 2 is slid backward, the cover plate 2 can synchronously drive the guide plate 5 to slide backward until the guide plate 5 moves to the limit distance, and the connecting shaft 51 passes over the protrusion 23 and enters the guide groove 21.

[0031] In addition, a second stop block 6 is provided on the bottom wall of the through slot, and a stop plate 22 adapted to the second stop block 6 is provided on the front bottom surface of the cover plate 2. In this way, the second stop block 6 cooperates with the stop plate 22 to reduce the impact of the cover plate 2 on the guide plate 5 when the user slides the cover plate 2 backward too quickly. Example

[0032] Reference Figure 1 , Figure 2 On the basis of the first embodiment, this embodiment further provides a trolley case, comprising the above-mentioned case body 1 structure; a trolley assembly 3 and rollers 4 are installed on the case body 1.

[0033] The box body 1 includes a front side panel 11, a left side panel, a right side panel, a rear side panel 14 and a bottom panel. The bottom panel is hinged to the rear side panel 14. The left side panel and the right side panel are hinged to the front side panel 11 and the rear side panel 14. The left side panel is composed of two hinged left panels 13, and the right side panel is composed of two hinged right panels 12. The bottom end of the front side panel 11 is provided with a bearing portion (not shown) for bearing the bottom panel. With the above structure, the box body 1 can be quickly folded.

[0034] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
