Threaded stud structure of plastic part

Abstract

The invention discloses a threaded stud structure of a plastic part, which comprises a plastic part, a first part and a second part, wherein the inside surface of the plastic part is provided with a concave meat-stealing area, a threaded stud is arranged in the meat-stealing area, a nut is arranged in the threaded stud and the periphery of the bottom part of the threaded stud is provided with a plurality of ribs; the first part is provided with a through hole through which the first part is sleeved on the threaded stud, the end, provided with the nut, of the threaded stud is exposed after thestud passes through the through hole, and the ribs arranged on the periphery of the threaded stud are pressed against the face, on which the through hole is arranged, of the first part respectively; and the inside surface of the second part is provided with a through hole post which is jointed with the threaded stud. The ribs arranged on the periphery of the threaded stud are pressed against the face, on which the through hole is arranged, so when a screw is to be locked, the screw passes through the through hole post to be screwed into the nut on the threaded stud and the first part and the ribs are main stressed points. Thus, the phenomenon that a dent is produced on the surface of the plastic part as the threaded stud is pulled to sink is eliminated.

Description

【Technical field】 [0001] The invention relates to a threaded post structure, in particular to a threaded post structure for plastic parts. 【Background technique】 [0002] Electronic products often design threaded column structure as the connection between parts, and some plastic parts are designed with threaded column structure, and there will be a recessed meat stealing area around the inner surface corresponding to the threaded column. [0003] Please refer to figure 1 , figure 2 , which are respectively shown as an assembly schematic diagram of the threaded post structure of the plastic part in the prior art, and an exploded schematic view of the threaded post structure of the plastic part in the prior art. [0004] The threaded column structure of the plastic part includes: a plastic part 1, a recessed meat-stealing area 2 is provided on its inner surface, a threaded column 3 is arranged on the meat-stealing area 2, and a nut 4 is arranged inside the threaded column 3...

AI Technical Summary

Problems solved by technology

[0005] Utilizing the threaded post structure of the above-mentioned plastic parts, due to mold manufacturing and molding tolerances, it is difficult to make the size exactly the same as the design. There is often a small gap between the connecting surface of the threaded post 3 and the through-hole post 8. The surface of the threaded column 3 behind the hot-melt nut 4 is often uneven and the hole position of the threaded column 3 is eccentric. When the screw 9 is locked, the threaded column 3 is often pulled down and the outer surface of the plastic part 1 is dented, especially Some thin-walled plastic parts are prone to this problem
