[0029] The utility model is described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-3 As shown, a trolley case with a frame connection structure comprises an upper case 1 and a lower case 11, wherein an upper connection frame 14 formed by plastic material is glued to the opening of the upper case 1 by glue, and a lower connection frame 15 formed by plastic material is glued to the opening of the lower case 11 by glue;

[0031] The upper connection frame 14 is formed with an upper bonding groove 16 along the frame structure direction thereof, and the opening of the upper box body 1 is formed with an upper bonding block 12 embedded in the upper bonding groove 16;

[0032] The lower connection frame 15 is formed with a lower bonding groove 17 along the frame structure direction thereof, and the opening of the lower box body 11 is formed with a lower bonding block 13 embedded in the lower bonding groove 17;

[0033] This product uses an upper connecting frame 14 and a lower connecting frame 15 made of plastic material, which, combined with the upper box body 1 and the lower box body 11, can greatly improve the strength and shape of the product as a whole, avoiding the disadvantage of the variability of the original zipper combination, and realizing surface sewing combination, saving costs, increasing strength, and beautifying the product appearance. In addition, the plastic frame product is injection molded, which can be produced in different colors, and produce contrasting colors with the trolley case, which is beautiful and beautifying.

[0034] A locking structure and a mosaic structure are provided between the upper connecting frame 14 and the lower connecting frame 15; the upper connecting frame 14 and the lower connecting frame 15 can be connected and separated with each other through the locking structure and the mosaic structure, and the overall combination adopts environmentally friendly glue, so there are no screws or nails on the appearance, which improves the appearance of the trolley case.

[0035] Preferably, the upper box body 1 and the lower box body 11 are both formed by hard plastic material.

[0036] Preferably, the upper connecting frame 14 and the lower connecting frame 15 are both made of ABS+PC material by injection molding.

[0037] Specifically, the interlocking structure includes a raised strip 18 formed along the length direction of the lower connecting frame 15, and the upper connecting frame 14 is formed with a concave long groove 19 along its length direction for the raised strip 18 to be embedded in, and the raised strip 18 is coaxially aligned with the concave long groove 19; when the upper box body 1 and the lower box body 11 are closed, the upper connecting frame 14 and the lower connecting frame 15 are fitted together, so that the raised strip 18 is embedded in the concave long groove 19. After fitting, the upper box body 1 and the lower box body 11 will not shift laterally.

[0038] Furthermore, the raised strip 18 is formed with a raised engaging block 2 at at least one point along the way, and the concave long groove 19 is formed with an engaging groove 21 for the engaging block 2 to be embedded in along the length direction. When the upper box body 1 and the lower box body 11 are closed, the upper connecting frame 14 and the lower connecting frame 15 fit together, so that the raised strip 18 is embedded in the concave long groove 19, and the engaging block 2 is further embedded in the engaging groove 21.
