Abstract

A plastic product locking mechanism capable of accurately positioning comprises a plastic product and a boss with a positioning rib. A penetration hole is formed on the plastic product; a mounting hole is formed in the boss; and a screw is fixed with the mounting hole in the boss through the penetration hole. The plastic product locking mechanism is characterized in that a positioning ring is arranged on an outer ring of the penetrating hole on the plastic product; a clamping groove is formed on the positioning ring; and the positioning rib on the boss is matched with the clamping groove on the positioning ring. The plastic product is provided with the positioning ring which is provided with the clamping groove; during assembly, when the boss with the positioning rib gets a twisting moment produced by the locking of an electric or pneumatic tool screw driver and needs to rotate, the clamping groove on the positioning ring of the plastic product is matched with the positioning rib, to limit and position the boss and prevent the boss from rotating, and accordingly, the purposes of mutually matching the boss with the plastic product, accurately positioning and preventing the rotation are achieved, the production efficiency is improved, the appearance of the product is ensured and the expected effect for assembly is achieved.

Description

Precisely the plastic article of location lock is paid mechanism

Technical field

The utility model relates to the plastic article lock of accurate location and pays mechanism.Lock when mainly being applicable to erection column (BOSS) with plastic article via hole location is paid structure.As automobile plastic goods, motorcycle plastic goods, household appliances plastic article.

Background technique

Along with plastic article the improving constantly of industry, popularization in the daily living article and usage requirement, the plastic article lock is paid a structure and more and more is tending towards complicated variation.Erection column (BOSS) adopts the lock of location to pay structure with the perforation of plastic article and also is used widely.It is following several that this class lock is paid structure general employing when product specification:

(a), positioning bar (RIB) 2 ' upper-end surface 21 of (as shown in Figure 1) erection column (BOSS) 3 ' on every side ' than erection column (BOSS) 3 ' low 2.5～3mm, plastic article 1 ' on perforation 11 ' diameter than the big 0.5～1mm of erection column (BOSS) 3 ' diameter, when lock is paid, positioning bar (RIB) upper-end surface 21 ' be adjacent to plastic article 1 ' contact, perforation 11 on the plastic article of erection column (BOSS) 3 ' penetrate ', and, erection column (BOSS) upper-end surface is assembled urgent than the locking action face 5 ' low 0.5mm of plastic article perforation place.

(b), (as shown in Figure 2) positioning bar (RIB) 2 ' upper-end surface 21 of erection column (BOSS) 3 ' on every side ' than erection column (BOSS) 3 ' low 2.5～3mm, plastic article 1 ' on perforation 11 ' diameter littler than erection column (BOSS) 3 ' diameter, plastic article 1 ' above have positioning ring 12 ', its inner side surface is an inclined-plane 6 ' a play a part guide-localization, when lock is paid, positioning bar (RIB) 2 ' upper-end surface 22 ' with plastic article 1 ' on positioning ring 12 ' go up end face contact and be adjacent to, the round positioning ring of erection column (BOSS) 3 ' be positioned at central authorities, its end face and plastic article stay the 0.5mm gap, assemble urgent.

But when goods practical set lock is paid, it all is that Dan Zusuo pays at present that the lock of self tapping screw is paid, because of there not being position structure accurately, and use electronic on the production line or the pneumatic tool screw-driver is locked and paid, torsion is bigger, often the phenomenon that can occur rotating when lock is paid, occurring product unavoidably scratches, seriously influenced the appearance quality of goods, can't reach the Expected Results of assembling, manufacturing efficiency is low.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming that prior art exists, a kind of accurate positioning is provided, make erection column (BOSS) when the assembling lock is paid, can not rotate phenomenon, guarantee erection column (BOSS) appearance quality, enhance productivity, satisfy the Expected Results of assembling, lock is paid the plastic article lock of more reliable accurate location and is paid mechanism.

The utility model precisely technological scheme of the plastic article lock pair mechanism of location is: the erection column that comprises plastic article and band positioning bar, on plastic article, have perforation, in erection column, have mounting hole, screw fixes by the mounting hole in perforation and the erection column, it is characterized in that the perforation outer ring on the described plastic article is shaped on positioning ring, have draw-in groove on positioning ring, the positioning bar on the erection column matches with draw-in groove on the positioning ring.

The plastic article lock that the utility model discloses a kind of accurate location is paid mechanism, on plastic article, be shaped on positioning ring, open draw-in groove on the positioning ring, during assembling, when the erection column (BOSS) of band positioning bar (RIB) is subjected to paying and the moment of torsion that produces will rotate the time from electronic or pneumatic tool screw-driver lock, draw-in groove on the plastic article positioning ring matches with positioning bar (RIB), (BOSS) carries out qualifying bit to erection column, stop its rotation, cooperatively interact with plastic article thereby reach erection column (BOSS), precisely the location, prevent the purpose of rotating, enhance productivity, guarantee products appearance, reach the assembling Expected Results.

The utility model precisely plastic article lock of location is paid mechanism, the diameter of boring a hole on the described plastic article

External diameter less than erection column (BOSS)

Perhaps Chuan Kong diameter

Greater than erection column (BOSS) external diameter The diameter of perforation

External diameter less than erection column (BOSS)

The time, erection column (BOSS) contacts with plastic article and is adjacent to, and screw needs to squeeze in the mounting hole of erection column (BOSS) by perforation; The diameter of perforation

Greater than erection column (BOSS) external diameter

The time, the head of erection column (BOSS) inserts in the perforation, and screw is directly squeezed in the mounting hole of erection column (BOSS).
