Plugging buckle of pluggable toy with rectangular section

Abstract

The invention discloses a plugging buckle of a pluggable toy with the rectangular section. The plugging buckle comprises protrusions and pits, and is characterized in that the protrusions and the pitswhich are matched are formed in the positions, beside the central axis in the plugging direction, of the contact faces of two plugging pieces of a plugged part of the pluggable toy with the rectangular section correspondingly; and thus the contact faces of the two plugging pieces of the plugged part of the plastic pluggable toy are interlocked through matching of the protrusions and the pits in the faces of the two plugging pieces, meanwhile the positions beside the central axes of the contact planes of the plastic plugging pieces have the degreeof freedom of moving towards the two sides perpendicular to the planes when being under the pressure, and thus elastic force generated by moving towards the two sides perpendicular to the planes from the position beside the central axes of the contact planes due to the protrusions can be controlled by controlling the thicknesses of the contact planes of the plastic plugging pieces and the heights of the protrusions. Thus the toy plugging buckle suitable for the strength of children can be made.

Description

technical field [0001] The invention relates to a plastic plug-in toy part, in particular to a plug-in buckle of a rectangular cross-section plug-in toy. Background technique [0002] The disadvantage of the current plastic plug-in toys is that the strength and firmness of the assembled toys are not high, and they are easy to fall apart. At present, the commonly used fastening method is to add uniformly distributed raised strips or reduce the fit tolerance in the plug-in toy, but the problem is that the pressure generated by the raised strips or reduced fit tolerance may be too large, and children do not have the strength to insert. . Contents of the invention [0003] The object of the present invention is to provide a plug-in buckle for a plug-in toy with a rectangular cross-section, which can solve the problem of plug-in and stable connection of the plug-in toy with a rectangular cross-section, is convenient and simple to use, and is suitable for children with small st...

[0002] The disadvantage of the current plastic plug-in toys is that the strength and firmness of the assembled toys are not high, and they are easy to fall apart

At present, the commonly used fastening method is to add evenly distributed raised strips or reduce the fit tolerance in the plug-in toy, but the problem is that the pressure generated by the raised strips or the reduced fit tolerance may be too large, and children do not have the strength to insert.
