Abstract
The utility model provides an improved structure of a take-up lever of a sewing machine, which is characterized in that a transverse notch is arranged on a long slotted hole.
Description
Technical Field
The utility model relates to the technical field of sewing equipment parts, in particular to an improved thread take-up lever structure of a sewing machine.
Background
In the sewing process of clothes, a machine needle drives a suture to be pricked into a product to be sewn, a hook mechanism hooks an upper thread, the hook mechanism releases the upper thread, the upper thread is tightened through a take-up lever after the upper thread is released, the upper thread is interwoven with a bottom thread to form a stitch, the sewing of the article is finished, the movement track of the take-up lever is fixed, the tension of the upper thread on the upper thread is different when the take-up lever tightens the upper thread at different positions in the sewing process, the tension of the suture can be changed in the sewing process, the sewing central line of the clothes is unstable, the sewing effect and the sewing quality of the clothes are influenced, an applicant invents a take-up lever structure of the sewing machine, the sewing central line of the clothes is effectively ensured to be stable, the sewing effect and the sewing quality of the clothes are better ensured, in the utility model, the thread can instantly slide down to the bottom of a long slotted hole from the top end of the take-up lever due to the tension of the thread when the take-up lever rises, allowing the suture to relax more quickly and thereby affecting the suture stitches.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides an improved thread take-up lever structure of a sewing machine, in the sewing process, the thread feeding amount of the upper thread and the pulling force of the upper thread are kept stable when the thread take-up lever runs to different positions, so that the stability of stitches in the sewing of clothes is further ensured, and the sewing effect and the sewing quality of the clothes are improved.
The technical scheme is as follows: an improved thread take-up lever structure of a sewing machine is characterized in that a transverse notch is arranged on a slotted hole.
It is further characterized in that: the threading hole is an arc-shaped hole; the connection part of the long slotted hole and the transverse notch is an arc transition section.
By adopting the scheme, the transverse notch is formed in the long slotted hole, when the thread runs to the end part of the long slotted hole, the thread stays in the transverse notch for a certain time, the take-up in the sewing process is ensured, the thread quantity matched with the thread passing quantity is better ensured, and the thread feeding quantity of the upper thread and the tension of the upper thread are kept stable when the take-up lever runs to different positions in the thread hooking process of the thread hooking mechanism, so that the tension of the thread is more stable, the stitches in the sewing of the clothes are more stable, the sewing effect and the sewing quality of the clothes are further ensured, and the breakage of the upper thread is further avoided.
Drawings
FIG. 1 is a schematic view showing the structure of the improved thread take-up lever of the sewing machine according to the present invention.
Detailed Description
See fig. 1, an improved sewing machine thread take-up lever structure, its package sewing machine thread take-up lever body 1, set up through wires hole 2 on the sewing machine thread take-up lever body 1, through wires hole 2 is the slotted hole, set up horizontal breach 3 on the slotted hole 2, when moving to the slotted hole tip on line, the line can stay the certain time in horizontal breach, guarantee the receipts line of making up the in-process, better guarantee with cross line volume assorted line volume, the quantity of sending of line and the pulling force of upper thread of making the thread take-up lever when moving to different positions remain stable, make the tension of suture more stable, the stitch is more stable in making up of clothing, further guaranteed the effect of making up of clothing and make up the quality, further avoid the fracture of upper thread simultaneously.
The threading holes 2 are preferably arc-shaped slotted holes. So that the running of the suture in the threading hole is smoother.
The joint of the long slotted hole 2 and the transverse notch 3 is an arc transition section 4, so that the running resistance of the suture is reduced, the thread breakage is prevented, and the suture runs more smoothly.
The thread hooking mechanism generally comprises a rotary shuttle and a shuttle hook.
The stay time of the suture is controlled according to the length of the transverse gap, so that the synchronization of the thread hooking mechanism and the take-up and paying-off of the thread take-up lever is ensured.
The present invention and its embodiments have been described in detail, without limitation, and the accompanying drawings are only one embodiment of the utility model, and the actual structure is not limited thereto, so long as those skilled in the art can design the structure and the embodiments similar to the above technical solution without departing from the spirit of the utility model.
Claims (3)
