Detailed Description
The following describes the embodiments of the present utility model in further detail with reference to fig. 1 and examples.
According to fig. 1, the embodiment comprises an upper shell and a lower shell, and the upper shell and the lower shell are buckled to form an outer shell; the two reinforcing plates in the outer shell are parallel to each other
The outer shell is provided with a vertical hole and a horizontal hole; wherein, the hole wall forming the vertical hole comprises a first cylindrical extension integrally formed with the upper shell, a second cylindrical extension integrally formed with the lower shell and a third cylindrical extension integrally formed with the reinforcing plate; the first cylindrical extension, the second cylindrical extension and the third cylindrical extension which are opposite to each other are positioned on the same axis; and each reinforcing plate is provided with a corresponding third cylindrical extension, and the extension directions of the third cylindrical extensions on the two reinforcing plates are opposite.
The hole wall forming the horizontal hole comprises a half hole wall arranged on the reinforcing plate; the adjacent surfaces of the two reinforcing plates are tightly attached, and the two opposite half hole walls are buckled to form a complete horizontal hole wall. The horizontal and vertical holes are present at the same time to accommodate more other components; and, this embodiment plugs into the horizontal or vertical holes through half of the square posts, and the other half plugs into other components, such as wheels.
The middle part of the bottom surface of the outer shell is an arc convex surface, and when the square component is used as a bottom plate of the trolley, a child sits on the top of the upper shell; the arc ground can play a role in reducing the center, and the structural strength of the middle part can be enhanced, so that accidents caused by fracture are prevented.
The adjacent surfaces of the outer shell body are in smooth transition, no obvious edge exists, and children are prevented from being knocked.
Furthermore, the vertical holes and the horizontal holes are square holes, so that the connection is more stable, and compared with the round holes.
The upper shell and the lower shell are connected through screws; the inner side of the upper shell and the inner side of the lower shell are respectively provided with a connecting column which is integrally formed with the upper shell and the lower shell, and screw holes are formed along the central axis of the connecting column; the screw hole of the upper shell connecting column is opposite to the screw hole of the lower shell connecting column and is connected through a screw. And the structure of the outer shell can be realized by mortise-tenon fit.
And pin holes corresponding to the connecting columns or the screws are formed in the reinforcing plate. The connecting column and the side wall of the outer shell adjacent to the connecting column are provided with reinforcing ribs for reinforcing the strength of screw connection.
Referring to fig. 2, the square assembly of the present embodiment serves as the chassis of the splice cart. The components are connected through inserted prismatic columnar structures, and the prismatic columnar structures are locked with the components through hard friction, a bean ejection switch or buckle connection.
In the embodiment, the horizontal hole is established by adopting a mode of laminating two reinforcing plates, so that the manufacturing cost is lower; if only the upper shell and the lower shell are provided, the strength of the technical scheme provided by the embodiment is obviously insufficient, and the connection between the square column and the horizontal hole or the vertical hole is not stable.
