Automatic Cord Inserting Structure for a Venetian Blind

摘要

An automatic cord inserting structure for a venetian blind is fixed on an automatic slat insertion machine including a pushing mechanism and a slat fixing mechanism. The pushing mechanism pushes a slat toward the slat fixing mechanism, and the slat fixing mechanism includes a sliding rack and plural automatic infixing modules. Each automatic infixing module contains: a base having a front face, a rear face, a horizontal slot, and a vertical slot; two limiting pieces for limiting the cord assembly slid in the vertical slot; two abutting pieces fixed in the horizontal slot, and each abutting piece having a lock portion locked on the base and a contacting portion; two elastic units mounted among the base and the two abutting pieces to abut against the two abutting pieces, when the abutting pieces are not pushed by the slat, they are fixed in the horizontal slot.

1. An automatic cord inserting structure for a venetian blind being fixed on an automatic slat insertion machine for the venetian blind, and the automatic slat insertion machine including a pushing mechanism and a slat fixing mechanism, the pushing mechanism pushing a slat toward the slat fixing mechanism, the slat fixing mechanism including a sliding rack and plural automatic infixing modules arranged on the sliding rack, and each automatic infixing module having:
a base having a front face, a rear face, a horizontal slot formed on a first top end thereof to insert the slat, and a vertical slot formed on the front face to slide a cord assembly; two limiting pieces locked on the front face of the base and limiting the cord assembly slid in the vertical slot; two abutting pieces, each abutting piece having a lock portion and a contacting portion, wherein the lock portion are locked on the base, and the two abutting pieces are normally fixed in the horizontal slot of the base, and when the slat is fixed in the horizontal slat, the two abutting pieces are pushed by the slat to rotate, the two contacting portions of the two abutting pieces extend out of the front face of the base to pull the cord assembly tightly, thus inserting the slat-into the cord assembly; and two elastic units mounted among the base and the two abutting pieces to abut against the two abutting pieces, and when the abutting pieces are not pushed by the slat, they are fixed in the horizontal slot of the base automatically.
