Embodiment Construction

[0016] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings and examples. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present invention.

[0017] Such as figure 2 , image 3 , Figure 4 As shown, the technical solution of the present invention is to design a threaded assembly structure for 3D printed plastic parts, including plastic parts (12) with embedded metal nuts and round head screws (13).

[0018] Wherein the plastic parts (12) with pre-embedded metal nuts can be mass-produced through injection molding of plastic molds, and the thread type is made into standard parts; the round head screws (13) are ordinary machine screws.

[0019] The connection relationship is: the plastic part (12) of the embedded metal nut is inserted into the installation groove of the lower casing (14) fr...

Abstract

The invention aims to overcome the assembly defects of an existing 3D printing plastic part and designs a simple and reliable threaded assembly structure for the 3D printing plastic part. The threaded assembly structure comprises a round head screw and the plastic part with a metal nut embedded. The structure is mainly applied to the mechanical structure industry and efficiently solves the problems that a self-tapping screw cannot be disassembled frequently after being connected, and a threaded stud is cracked or the screw is loosened during assembly of a shell of the existing 3D printing plastic part.

Description

technical field [0001] The invention belongs to the field of mechanical structures and relates to a thread assembly structure of 3D printed plastic parts. Background technique [0002] At present, 3D printing technology has been developed rapidly, especially the most mature in resin plastics. The rapid prototyping of products is one of the main applications of 3D printing technology. 3D printed prototype products are mainly used for the verification of appearance and function, or the shell of small batch products. Generally, one or more 3D printed prototypes are made in the early stage of new product development for assembly and various experiments. Existing assembly methods such as figure 1 As shown: the existing upper shell (1) and the existing lower shell (3) are first assembled together through the positioning of the seam, and then the self-tapping screw (2) passes through the existing upper shell (1) and screwed Insert the screw column of the existing lower casing (3...
