Abstract
The present invention provides a kind of thread take-up lever structure of sewing machine, during sewing, the pulling force of the line sending amount of upper thread and upper thread keeps stablizing when thread take-up tension lever runs to different location, so that stitching is stablized in the sewing of clothing, it preferably ensure that the sewing effect and sewing quality of clothing, threading hole is arranged on the thread ran of sewing machine body in its packet thread ran of sewing machine body, and threading hole is long slot bore.Since the threading hole on thread ran of sewing machine body is long trough threading hole, when thread ran of sewing machine runs to lower end, become larger for line amount, it ensure that string-hooking mechanism crosses the demand of line amount, during thread ran of sewing machine runs to upper end, extra line amount quickly recycles, preferably provide and cross the line amount that line amount matches, so that the line resistance excessively of string-hooking mechanism is smaller, the pulling force of the line sending amount of upper thread and upper thread keeps stablizing when thread take-up tension lever runs to different location, so that the tension stability of suture, stitching is stablized in the sewing of clothing.
Description
Technical field
The present invention relates to the technical field of sewing device component, more particularly to a kind of thread take-up lever structure of sewing machine.
Background technology
During the sewing of clothing, eedle drives suture to penetrate and waits in sewed product, after string-hooking mechanism catches on upper thread, hooking
Mechanism discharges upper thread, tightens upper thread by thread take-up tension lever after upper thread release, interweaves with forming stitching with baseline, complete the seam of article
System, since the movement locus of thread take-up tension lever is fixed, during thread take-up tension lever tightens upper thread, upper thread is in different location to upper thread
Tightening force is different, and the tension of suture can change during sewing, and it is unstable to cause stitching in the sewing of clothing, to
Affect the sewing effect and sewing quality of clothing.
Invention content
For the deficiency of the prior art, the present invention provides a kind of thread take-up lever structure of sewing machine, during sewing, thread take-up tension lever
The pulling force of the line sending amount of upper thread and upper thread keeps stablizing when running to different location, so that stitching is steady in the sewing of clothing
It is fixed, it preferably ensure that the sewing effect and sewing quality of clothing.
Its technical solution is such：A kind of thread take-up lever structure of sewing machine, packet thread ran of sewing machine body, the sewing machine
Threading hole is set on the take-up body of rod, and threading hole is long slot bore.
Threading hole both ends are arc-shaped；The threading hole is oval long slot bore.
The present invention using the above scheme, since the threading hole on thread ran of sewing machine body is long trough threading hole, works as sewing
When machine thread take-up tension lever runs to lower end, become larger for line amount, ensure that string-hooking mechanism crosses the demand of line amount, when thread ran of sewing machine is run
To during upper end, extra line amount quickly recycles, and preferably provides and cross the line amount that line amount matches so that string-hooking mechanism
Cross that line resistance is smaller, the pulling force of the line sending amount of upper thread and upper thread keeps stablizing when thread take-up tension lever runs to different location so that suture
Tension stability, in the sewing of clothing stitching stablize, preferably ensure that the sewing effect and sewing quality of clothing, simultaneously also have
Effect avoids the fracture of upper thread.
Description of the drawings
Fig. 1 is thread take-up lever structure of sewing machine schematic diagram of the present invention；
Fig. 2 is thread take-up lever structure of sewing machine motion state schematic diagram of the present invention.
Specific implementation mode
See Fig. 1, Fig. 2, a kind of thread take-up lever structure of sewing machine, packet thread ran of sewing machine body 1 is set on thread ran of sewing machine body
The threading hole 2 for setting elongated slot hole shape becomes larger when thread ran of sewing machine runs to lower end for line amount, ensure that string-hooking mechanism mistake
The demand of line amount, during thread ran of sewing machine runs to upper end, extra line amount quickly recycles, and preferably provides and crosses line
Measure the line amount to match so that the line resistance excessively of string-hooking mechanism is smaller, the line sending amount of upper thread when thread take-up tension lever runs to different location
It keeps stablizing with the pulling force of upper thread so that the tension stability of suture, stitching is stablized in the sewing of clothing, preferably ensure that clothing
Sewing effect and sewing quality, while also effectively avoiding the fracture of upper thread.
In embodiment, threading hole both ends are arc-shaped, are specifically designed ovalisation and effectively reduce suture in threading hole
The resistance of movement preferably ensure that the tension stability of suture, and stitching is stablized in the sewing to further ensure clothing, into
The sewing effect and sewing quality of one step raising clothing and the fracture for effectively avoiding upper thread.
3 be suture location in threading hole when thread ran of sewing machine moves to upper and lower ends in attached drawing.
String-hooking mechanism generally includes rotating shuttle and shuttle.
Schematically the present invention and embodiments thereof are described above, description is not limiting, institute in attached drawing
What is shown is also one of embodiments of the present invention, and actual structure is not limited to this, as long as thread ran of sewing machine body threads
Hole is designed as long groove shape, can realize that string-hooking mechanism crosses the demand of line amount and the conveying capacity of upper thread matches so that of suture
Power is stablized, and stitching is stablized in the sewing of clothing, preferably ensure that the sewing effect and sewing quality of clothing, while also effectively keeping away
Exempt from the fracture of upper thread, those skilled in the art are enlightened by it, in the case where not departing from this creation objective, without creation
Property designs frame mode similar with the technical solution and embodiment, is within the scope of protection of the invention.
