Description
Technical Field
The present invention relates to the field of folding container technology, and more particularly to an annular joint structure for a composite folding container.
Background
As shown in fig. 1, there is a composite folding container which is mainly composed of a soft wall and a hard wall which are combined together, the composite material folding container mainly comprises a hard lower wall 11, a soft middle wall 12 and a hard upper wall 13 which are connected in sequence, wherein the hard lower wall 11 and the hard upper wall 13 are respectively provided with connecting protrusions 111 and 131 which are protruded towards the soft middle wall 12, and the engagement protrusions 111, 131 are provided at the tips thereof with snap- fit protruding rings 112, 132, as can be understood from the side sectional view of FIG. 1, the thickness of the engagement protrusions 111, 131 becomes thinner as they approach the soft middle wall 12, the engaging protrusions 111, 131 are provided with locking protrusions 112, 132 at the top ends nearest to the soft middle wall 12, the soft middle wall 12 has an engaging groove 121 facing the hard lower wall 11 and the hard upper wall 13, the bottom of the engagement groove 121 is provided with a locking concave ring 122, the closer the engagement groove 121 is to the groove bottom, the smaller the groove diameter, and the groove bottom is provided with the locking concave ring 122.
The engaging protrusions 111, 131 of the hard lower wall 11 and the hard upper wall 13 are engaged with the engaging grooves 121, and the engaging convex ring 112 is engaged with the engaging concave ring 122 in a concave-convex manner, thereby preventing the hard upper wall 13 and the hard lower wall 11 from being separated from each other in the engaging direction of the hard lower wall 11, the soft middle wall 12 and the hard upper wall 13.
It is worth mentioning that the engaging protrusions 111, 131 are seen from the cross-sectional view in fig. 1, and have inner wall surfaces 1111, 1311 facing the inner space of the folding container, and outer wall surfaces 1112, 1312 opposite to the inner wall surfaces 1111, 1311, and the inner wall surfaces 1111, 1311 extend from the hard upper wall 13 or the hard lower wall 11 to the locking convex rings 112, 132 for the same length as the outer wall surfaces 1112, 1312, that is, the cross-sectional view of the engaging protrusions 111, 131 is generally in the shape of an isosceles triangle, and when a user folds the container, the user must move the hard lower wall 11 toward the hard upper wall 13, the soft middle wall 12 must be folded outward near the position connecting the hard lower wall 11, and the soft middle wall 12 must be folded inward near the position connecting the hard upper wall 13, so that the hard lower wall 11 can be folded into the hard upper wall 13.
However, since the inner walls 1111, 1311 and the outer walls 1112, 1312 are of equal length in the folding direction, when the user wants to fold the container, the user cannot directly guide the soft middle wall 12 to fold outward near the position connected to the hard lower wall 11, or guide the soft middle wall 12 to fold inward near the position connected to the hard upper wall 13, which causes inconvenience in folding.
Furthermore, the hard lower wall 11 and the hard upper wall 13 are only fixed by the locking convex rings 112, 132, and only the hard upper wall 13, the soft middle wall 12 and the hard lower wall 11 can be prevented from being separated along the joint direction, when the user displaces the hard upper wall 13 along the transverse direction, the position where the soft middle wall 12 is jointed with the hard upper wall 13 is deformed, one surface of the jointing protrusions 111, 131 is tightly adhered to one surface of the jointing groove 121, and the other surface of the jointing groove 121 is incompletely adhered to the jointing protrusions 111, 131 due to the deformation, so that the problem that the hard lower wall 11, the soft middle wall 12 and the hard upper wall 13 are separated from each other still exists.
