Technical Field

[0001] This utility model relates to the field of sewing machine technology, and in particular to a pattern fine-tuning structure for a multi-functional household sewing machine. Background Technology

[0002] Currently, most sewing machines on the market require high-precision sewing of the corresponding needle bar assembly to meet the quality requirements of sewing patterns. This necessitates high precision in the needle bar assembly components and assembly, significantly increasing production costs and making it difficult to meet market demands. Furthermore, after prolonged use, the needle bar assembly develops errors, requiring position adjustment. This necessitates disassembly for adjustment, which is cumbersome, time-consuming, and labor-intensive, further increasing labor costs and resulting in unsatisfactory practical application effects. Utility Model Content

[0003] This invention aims to overcome the shortcomings of the prior art by providing a pattern fine-tuning structure for a multifunctional household sewing machine. This structure enables fine-tuning of the left and right positions of the needle bar assembly used with the pattern, thereby reducing component precision, increasing work efficiency, and lowering costs.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: The pattern pattern fine adjustment structure of this multifunctional household sewing machine includes a pattern pattern, a pattern pattern pawl that corresponds to and matches the position of the pattern pattern, a baffle on the tail end of the pattern pattern pawl, a pattern pattern pawl swing frame on one side of the baffle, a screw on the pattern pattern pawl swing frame that can drive the pattern pattern pawl swing frame to adjust its left and right position, the screw is threadedly connected to the pattern pattern pawl swing frame, the tail end of the screw contacts the baffle, an guide plate is connected to the pattern pattern pawl swing frame that moves with the pattern pattern pawl swing frame, and a needle bar assembly that moves with the guide plate is connected to the guide plate.

[0005] Furthermore, a stop nut is connected between the screw and the pawl swing bracket of the pattern.

[0006] Furthermore, a spring connects the head end of the pattern pawl to the pattern pawl swing frame.

[0007] Furthermore, the flower pattern ratchet swing frame includes a swing frame head, a swing frame connecting part, and a swing frame tail, which are connected in sequence. The screw is set on the swing frame connecting part, and the swing frame head is connected to the guide plate.

[0008] Furthermore, a flower pattern ratchet support shaft is connected between the head and tail of the swing frame.

[0009] Furthermore, the screws used are internal hex screws.

[0010] The beneficial effects of this utility model are: the pattern fine-tuning structure of the multifunctional household sewing machine of this utility model has a reasonable structure. The position of the pattern pawl swing frame can be quickly adjusted by the internal hex screw, and the left and right positions of the needle bar assembly corresponding to the pattern can be quickly adjusted to achieve the effect of rapid fine-tuning. This can improve work efficiency, reduce the precision of parts, reduce production costs, and has good performance, which is conducive to promotion. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings:

[0015] Referring to the attached diagram: This multi-functional household sewing machine's pattern fine-tuning structure includes a pattern mold 1, used to form the sewing pattern of the sewing machine. The pattern mold 1 is equipped with a pattern mold pawl 2 that corresponds to and matches the position of the pattern mold 1. The pattern mold pawl 2 is used to match the pattern mold 1 for operation. A baffle 3 is provided at the tail end of the pattern mold pawl 2, which serves to block and position the pattern. A pattern mold pawl swing bracket 4 is provided on one side of the baffle 3, used to drive the pattern... The pattern pawl 2 operates. The pattern pawl swing frame 4 is equipped with a screw 5 that allows for left-right adjustment of its position. The screw 5 is threadedly connected to the pattern pawl swing frame 4, and its tail end contacts the baffle 3. An guide plate 6 is connected to the pattern pawl swing frame 4 and moves with it. A needle bar assembly 7, which moves with the guide plate 6, is connected to the guide plate 6. The needle bar assembly 7 is a conventional sewing machine needle bar structure, which will not be described further. The pattern 1 and the needle bar assembly 7 are linked. In operation, the fine-tuning of the needle bar assembly 7, also known as the fine-tuning of the pattern 1, can be achieved by turning the screw 5 inward or outward. Turning the screw 5 inward causes its bottom to rest against the baffle 3, moving the pattern pawl swing frame 4 inward, which in turn moves the guide plate 6 and the needle bar assembly 7 inward, effectively fine-tuning the needle bar assembly 7 to the right. Turning the screw 5 outward causes the pattern pawl swing frame 4 to move outward, which in turn moves the guide plate 6 and the needle bar assembly 7 outward, effectively fine-tuning the needle bar assembly 7 to the left. This allows for left-right adjustments to the needle bar assembly 7, improving work efficiency and reducing the precision required for components. By ensuring working accuracy through fine-tuning, the production cost of components is reduced, thus lowering the overall production cost. This approach, while maintaining quality, reduces costs and adapts to market demands.

[0016] A stop nut 8 connects the screw 5 to the pawl swing bracket 4 of the pattern. This design ensures that the screw 5 functions properly.

[0017] A spring 9 connects the head end of the pattern pawl 2 to the pattern pawl swing frame 4. This arrangement ensures the normal operation of both the pattern pawl 2 and the pattern pawl swing frame 4.

[0018] The flower pattern ratchet swing frame 4 includes a swing frame head 4-1, a swing frame connecting part 4-2, and a swing frame tail 4-3. The swing frame head 4-1, the swing frame connecting part 4-2, and the swing frame tail 4-3 are connected in sequence. Screws 5 are set on the swing frame connecting part 4-2. The swing frame head 4-1 is connected to the guide plate 6.

[0019] A flower pattern pawl support shaft 10 is connected between the head 4-1 and the tail 4-3 of the swing frame.

[0020] Screw 5 is a hex socket screw. This design allows for easy tightening, making it convenient to operate. Fine adjustments can be made using an hex wrench, improving user efficiency.

[0021] The features of this utility model embodiment are: the pattern fine-tuning structure of the multifunctional household sewing machine of this utility model has a reasonable structure. The position of the pattern pawl swing frame can be quickly adjusted by the internal hex screw, and the left and right positions of the needle bar assembly corresponding to the pattern can be quickly adjusted to achieve the effect of rapid fine-tuning. This can improve work efficiency, reduce the precision of parts, reduce production costs, and has good performance, making it easy to promote.

[0022] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
