Abstract
The utility model is a thread-taking-up mechanism of ruggedization machines and relates to component structure of sewing machines, comprising a thread-taking-up connecting rod, a crank and a thread-taking-up rod. One side of the thread-taking-up connecting rod is fixed on the shell by connecting rod pin and the other side is connected with the middle of the thread-taking-up rod actively; the bottom of the thread-taking-up connecting rod is connected with the crank actively; the connecting rod pin is composed of two cylinders with different axes; the medial cylinder punctures through the mounting hole on the shell and the lateral cylinder punctures through the shaft hole of the thread-taking-up connecting rod and is fixed to a screw. The screw on the outer side of the rotatory connecting rod pin and the eccentric column of the thread-taking-up connecting rod shaft produce the displacement, therefore, the thread-taking-up connecting rod moves the thread-taking-up rod to adjust the position and thread-taking-up amout of the thread-taking-up rod very conveniently.
Description
Technical field:
The utility model relates to the parts of Sewing machines, particularly the reinforcing machine thread take-up mechanism.
Background technology:
The thread take-up mechanism of existing reinforcing machine (also claiming bar tacking machine) is: link pin runs through the installing hole that penetrates behind the axis hole of line-choosing connecting rod on the casing, and the line-choosing connecting rod activity is fixed on the casing; The other end of line-choosing connecting rod with choose thread take-up tension lever middle part and flexibly connect.Wherein link pin is a concentric straight pin, and thread take-up tension lever is swung around link pin during work.The overhang of thread take-up tension lever is a fixed value, and the user generally can't adjust the overhang of thread take-up tension lever.If want to change the overhang of thread take-up tension lever, have only return-to-factory to change the position of installing hole on the casing, just can realize, so very inconvenient, and cause scrapping or changing of casing easily.
The utility model content:
The purpose of this utility model provides the reinforcing machine thread take-up mechanism that a kind of user can conveniently adjust the thread take-up tension lever overhang.
Scheme of the present utility model is: comprise line-choosing connecting rod, crank and thread take-up tension lever, wherein line-choosing connecting rod one end is fixed on the casing by link pin, the other end and thread take-up tension lever middle part flexibly connect, the thread take-up tension lever bottom flexibly connects with crank, link pin is made of two cylinders in different axle center, the inboard cylinder of link pin penetrates the installing hole on the casing, and outside cylinder passes the line-choosing connecting rod axis hole and screw is fixed.
The utility model has the advantages that: the screw of pivot link pin outer end, the eccentric cylinder that is coupling with line-choosing connecting rod produces displacement, moves thereby drive thread take-up tension lever by line-choosing connecting rod, can adjust the position and the take-up amount of thread take-up tension lever, and is very convenient.
Description of drawings:
Fig. 1 is a link pin enlarged drawing of the present utility model.
Fig. 2 is the utility model structural representation.
Fig. 3 is for being equipped with reinforcing machine head partial schematic diagram of the present utility model.
The specific embodiment:
Referring to figs. 1 through Fig. 3.Two cylinders 4.1,4.2 that link pin 4 makes into different axle center are the off-centre operation pin, link pin 4 inboard cylinders 4.2 penetrate the installing hole on the casing 5, it is fixing that outside cylinder 4.1 passes the axis hole and the screw 1 of line-choosing connecting rod 3, thread take-up tension lever 3 activities are fixed on the casing 5, and the effect of screw 1 is to prevent that line-choosing connecting rod 3 breaks away from from cylinder 4.1.The middle part of line-choosing connecting rod 3 other ends and thread take-up tension lever 2 flexibly connects, and the bottom of thread take-up tension lever 2 and crank 6 flexibly connect.
The screw 1 of pivot link pin 4 outer ends, inboard cylinder 4.2 is that rotate in the center of circle with the installing hole on the casing 5, produce bigger eccentric rotary with the eccentric cylinder 4.1 of 3 companies of line-choosing connecting rod, drive line-choosing connecting rod 3 displacements, line-choosing connecting rod 3 drives thread take-up tension lever 2 and swings up and down, thereby adjusts the position and the take-up amount of thread take-up tension lever.
The general user of the utility model just can adjust the take-up amount of thread take-up tension lever 2 by rotating screw 1, does not need return-to-factory to adjust installing hole on the casing 5, avoids scrapping or changing of casing 5; Make things convenient for the user on the one hand, when producer debugs on the other hand or after selling, needn't change the installing hole on the casing 5, improve and produce and maintenance efficiency.
