Toy assembly structure and dessert cabinet toy

ActiveCN224056668UEnhanced lateral torsional resistanceachieve a tight fitToysIndustrial engineeringFastener
The utility model relates to the technical field of toy assembling structures, in particular to a toy assembling structure and a dessert cabinet toy, which comprise an upper part and a lower part assembled below the upper part, a lower assembling hole is formed in the center of the top wall of the lower part, a lower sinking groove is formed in the outer side of the lower assembling hole, the upper assembling part comprises a plurality of sets of buckling parts, and the buckling parts are connected with the lower portions of the top walls of at least two sides of the lower part in a clamped mode. A front-back dual-clamping structure is formed by clamping a first clamping fastener at the bottom of the upper part, a clamping bump at the top of the lower part, a second clamping fastener at the bottom of the upper part and the top wall of the lower part, so that the lateral torsion resistance of the cabinet body is remarkably enhanced in an up-and-down assembly mode, tight joint attachment is realized, and the service life of the toy is prolonged; and the assembling convenience and the long-term use stability are both considered.
