Specific implementation method:
[0025] The present invention is further described below with reference to specific embodiments. Figure 1 —6:
[0026] The utility model provides a suitcase, which includes a box body 1 with one or both sides open, and a box cover 2 is arranged at the open end of the box body 1. When one side of the box body 1 of the suitcase is open, the suitcase is a single-side open structure. When the box body 1 of the suitcase is open on both sides, the suitcase is a double-side open structure. The box body 1 includes a front box body 3 and a rear box body 4. A plurality of first convex columns 5 are arranged at intervals on two opposite sides of the front box body 3, and the axis of the first convex column 5 is arranged along the length direction of the front box body 3. A plurality of second convex columns 6 are arranged at intervals on two opposite sides of the rear box body 4, and the axis of the second convex column 6 is arranged along the length direction of the rear box body 4. Through holes 7 are provided on the first boss 5 and the second boss 6. When the front box body 3 and the rear box body 4 are combined, the first boss 5 on the front box body 3 and the second boss 6 on the rear box body 4 are alternately arranged, and the front box body 3 and the rear box body 4 are connected by a connecting shaft 8 that penetrates the through holes 7 of the first boss 5 and the second boss 6.
[0027] The utility model realizes the front box body 3 and the rear box body 4 by respectively arranging the first convex column 5 and the second convex column 6 on the front box body 3 and the rear box body 4, and penetrating the through hole 7 of the first convex column 5 and the second convex column 6 through the connecting shaft 8, so that the connection structure is simple and the connection is fast and convenient.
[0028] In order to stabilize the structure, the distance between two adjacent first protrusions 5 is equal to the length of the second protrusion 6 , or the distance between two adjacent second protrusions 6 is equal to the length of the first protrusion 5 .
[0029] The utility model forms a tie rod seat installation position between the upper ends of the front box body 3 and the rear box body 4, and a connecting shaft seat installation position is set at the lower end. The tie rod seat 9 is set on the tie rod seat installation position between the front box body 3 and the rear box body 4, and the tie rod is installed on the tie rod seat 9. The connecting shaft seat 10 is set on the connecting shaft seat installation position, and the connecting shaft 8 is axially limited between the tie rod seat 9 and the connecting shaft seat 10.
[0030] In addition, the utility model also provides a tight fit connection between the connecting shaft 8 and the through hole 7. In this way, after the connecting shaft 8 and the through hole 7 are connected, there is basically no gap between the two, no shaking occurs, and the connection strength is improved.
[0031] The utility model can also provide knurling on the outer surface of the connecting shaft 9 to increase the friction between the connecting shaft and the through hole 7 .
[0032] It should be noted that the first protrusions 5 on both sides of the front box 3 are staggered. Similarly, the second protrusions 6 on both sides of the rear box 4 are also staggered. Specifically, the gap between the first protrusions 5 on one side of the front box 3 corresponds to the position of the first protrusions 5 on the other side. The second protrusions 6 on the rear box 4 are also distributed in the same way.
[0033] Through the above structure, combined with the mirror image setting of the front box 3 and the rear box 4, that is, the front box 3 and the rear box 4 of the utility model can adopt the same structure, and the second protrusion 6 on the other side of the rear box 4 can be just located between the first protrusions 5 on one side of the front box. Therefore, the box 1 formed by the front box 3 and the rear box 4 is open on both sides. In this way, the front box 3 and the rear box 4 can use a pair of molds, reducing the number of molds and greatly reducing the production cost of the enterprise.
[0034] The lower end sides of the front box body 3 and the rear box body 4 of the utility model are respectively provided with a first mounting column 11 and a second mounting column 12, and plug-in holes are respectively provided on the first mounting column 11 and the second mounting column 12. The two ends of the plug-in component are respectively inserted into the plug-in holes of the first mounting column 11 and the second mounting column 12 to achieve connection, and the first mounting column 11 and the second mounting column 12 can also be plugged into each other.
[0035] As for the installation of the connecting shaft seat 10, a mounting hole 17 parallel to the axis of the first mounting column 11 and the second mounting column 12 is provided on the inner side of the connecting shaft seat 10, and the corresponding first mounting column 11 and the second mounting column 12 on the front box body 3 and the rear box body 4 are inserted at both ends of the mounting hole 17 to achieve the fixation between the connecting shaft seat 10 and the front box body 3 and the rear box body 4. A boss 13 is provided on the outer side wall of the connecting shaft seat 10, and the boss 13 is clamped on the window 16 between the front box body 3 and the rear box body 4, and the boss 13 can achieve the limit of the lower end of the connecting shaft 8.
[0036] In addition, a plug hole 14 is provided at the upper end of the front box body 3 and the rear box body 4, and a plug post 15 whose number and position correspond to the plug hole 14 is provided on the pull rod seat 9, and the pull rod seat 9 is inserted into the plug hole 14 through the plug post 15 to realize the installation with the front box body 3 and the rear box body 4. The utility model also provides a plug hole 14 on the side wall of the upper end of the front box body 3 and the rear box body 4, so that the plug post 15 can be plugged with the plug hole 14 from two angles, and it is not easy to remove it from the front box body 3 and the rear box body 4 after plugging.
[0037] The above embodiment is only one of the preferred embodiments of the present utility model, and is not intended to limit the scope of implementation of the present utility model. Therefore, any equivalent changes made based on the shape, structure, and principle of the present utility model should be included in the protection scope of the present utility model.
