Description

A kind of manually sewing self-threading structure

Technical field

This utility model relates to sewing machine field, particularly relates to self-threading structure.

Background technology

In manual sewing process, threading is the step that the first step is carried out, owing to sewing needle string holes is little, Wire rod is softer, so normal artificial threading can devote a tremendous amount of time, for old people, Threading work also becomes abnormal difficult, so occurring in that self-threading structure on market, but this Plant in the hole that self-threading structure needs to insert sewing needle automatic threading structure when threading, logical Crossing and draw hook guiding wire rod threading, the most this operation can not disposably be directed at the pin hole of sewing needle, May result in sewing needle and the damage of self-threading structure, therefore there is defect.

Utility model content

For solving above-mentioned technical problem, this utility model provides one and manually sews self-threading Structure.

This utility model solves its technical problem and be the technical scheme is that this is manually sewed certainly Dynamic threading structure, it includes shell, threading block, locating piece and draws hook；Described shell includes pressure Tight spring and briquetting, described shell uses the housing of inner hollow, described upper surface of outer cover and under Surface is designed with sewing needle through hole, and described enclosure is designed with briquetting slide rail, and described briquetting is sliding Moving and be assemblied on described briquetting slide rail, described holddown spring one end is solid with described enclosure side Fixed connection, the other end is fixing with described briquetting to be connected；Described threading block is designed as end face and left and right Face is the housing of opening, and described threading block upper end is fixedly mounted on the through hole of described shell lower surface Place；Described locating piece is designed as tabular, and described locating piece lateral layout has through hole, described location Block is fixedly mounted on the right side of described outer casing bottom, and described locating piece through hole is left with described threading block Right side opening is on the same line；The described hook that draws includes back-moving spring, described in draw hook slidable fit On the through hole of described locating piece, described in draw be provided with between the tail end of hook and described locating piece multiple Position spring.

Described briquetting is designed as trapezium structure, and after described briquetting is installed, upper surface is that inclined-plane makes seam Swage can quickly position when installing.

Described threading block interior lower end is designed with magnetic block and makes sewing needle location more firm.

Described draw hook tail end be designed with promote plate be easy to described in draw promotion and the reset of hook.

Operation principle of the present utility model: sewing needle is inserted in described outer casing through hole by user, Owing to described briquetting is designed as trapezium structure, after described briquetting is installed, upper surface is that inclined-plane makes seam Swage can quickly position, so user can be quickly by the pin hole end of sewing needle when installing Being fixed in described shell, the most described holddown spring tightens up, and described briquetting is to two While move, sewing needle threading end inserts in described threading block, due to described threading block interior lower end Being designed with magnetic block, so sewing needle is attracted location more firmly, now sewing needle is fixed； Due to described draw hook tail end be designed with promote plate be easy to described in draw promotion and the reset of hook, institute so that User draws hook described in manually promoting, described in draw hook through pin hole, now wire rod is hooked in by user Described draw on hook, unclamp described in draw hook, under the effect of described back-moving spring, described in draw hook to Moving right wire rod through pin hole, now user is extracted sewing needle and is arranged wire rod, reaches automatic The purpose of threading.

Advantage of the present utility model: positioned, soon by the feature of shape at sewing needle pin hole Speed carries out threading accurately, and simple in construction is convenient.
