Technical Field
[0001] This utility model relates to the field of sewing machine pedal technology, specifically a labor-saving structure for a household sewing machine pedal. Background Technology
[0002] Traditional household sewing machine pedals are often designed with a fixed height. However, pedals that are too high or too low often force users to adjust their posture, which can easily lead to discomfort in the lower back and legs over time. Furthermore, different users may experience different issues. Children or shorter individuals may need to tiptoe to reach the pedal, which can cause calf muscle tension. Taller individuals, on the other hand, may need to bend over and bend their knees, increasing the burden on their lower back. Using the pedals in an unsuitable way for extended periods is not only strenuous but also causes discomfort. To address these problems, a more labor-saving design for household sewing machine pedals is needed.
[0003] Existing household sewing machine pedals cannot be adjusted to fit users of different heights and leg lengths. Children or shorter individuals may need to tiptoe to reach the pedal when using a fixed-height pedal, while taller individuals may need to bend over and kneel, increasing the burden on their lower back. Long-term use under unsuitable conditions is not only strenuous but also causes discomfort. When using the pedal with the foot, the pedal may flip, causing the foot to slide on the pedal, resulting in a disconnect between the foot and the pedal's force, making it impossible to accurately control the sewing machine's operation and leading to problems such as broken needles or threads. Therefore, there is an urgent need for a labor-saving structure for household sewing machine pedals. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a labor-saving structure for the pedal of a household sewing machine, in order to solve the problem that the existing household sewing machine pedals cannot be adjusted to fit the height of users with different heights and leg lengths. When children or shorter people use the fixed-height pedal, they may need to tiptoe to reach the bottom, while taller people need to bend over and bend their knees, increasing the burden on their waist. Long-term use under unsuitable conditions is not only laborious but also causes discomfort. When stepping on the pedal, the pedal may flip and the foot may slide on the pedal, causing the force of the foot to be disconnected from the pedal, making it impossible to accurately control the operation of the sewing machine, thus causing problems such as broken needles or threads.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a labor-saving structure for a household sewing machine pedal, comprising a frame, a plurality of adjustment holes on the side wall of the frame, a pedal installed on the side wall of the frame, a rotating shaft installed on both outer walls of the pedal, a bushing installed on the outer wall of the rotating shaft, a fixing rod installed on the side wall of the rotating shaft, a connecting rod installed on the outer wall of the pedal, a buckle installed on the outer wall of the pedal, and a limit elastic cord installed on the inner wall of the buckle.
[0006] Preferably, the adjustment holes are evenly distributed around the central axis of the frame sidewall, and the rotating shaft is symmetrically arranged around the central axis of the pedal.
[0007] Preferably, the bushing is engaged with the rotating shaft, and the bushing is inserted into the adjustment hole.
[0008] Preferably, the fixed rod is threaded to the inner wall of the rotating shaft, and the connecting rod is movably connected to the pedal.
[0009] Preferably, the buckle is slidably connected to the pedal, and the limiting elastic cord is engaged with the buckle.
[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through its frame, adjustment hole, pedal, rotating shaft, bushing, fixing rod, and connecting rod, allows users of different heights and leg lengths to adjust the pedal to a suitable height. The bushing is then engaged with the pedal, inserted into the appropriate adjustment hole, and secured with a threaded fixing rod. This allows users to use the device in the most comfortable sitting posture, avoiding excessive leg exertion and achieving both effort savings and improved comfort. Simultaneously, the smooth surface of the bushing reduces friction between the pedal and the frame, effectively improving the smoothness of pedal braking and enhancing practicality.
[0011] 2. This utility model uses a pedal, a buckle, and a limiting elastic cord. The limiting elastic cord is connected to the buckle. When using it, the user inserts both feet into the limiting elastic cord, and the buckle slides on the pedal. This allows the user to adjust the distance between the feet to a suitable position. The limiting elastic cord fits against the instep and generates a certain elastic compression force, preventing the feet from slipping off the pedal when stepping on it. This improves the stability of the connection between the feet and the pedal and avoids the phenomenon of the feet losing contact with the pedal and the speed control becoming uncontrollable.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0015] The embodiments of this utility model will be described below based on its overall structure.
[0016] Please see Figures 1-5 A labor-saving structure for a household sewing machine pedal includes a frame 1. Several adjustment holes 2 are provided on the side wall of the frame 1. A pedal 3 is mounted on the side wall of the frame 1. Rotating shafts 4 are mounted on both outer walls of the pedal 3. Bushings 5 are mounted on the outer walls of the rotating shafts 4. Fixing rods 6 are mounted on the side walls of the rotating shafts 4. Connecting rods 7 are mounted on the outer walls of the pedal 3. The adjustment holes 2 are evenly spaced around the central axis of the side wall of the frame 1. The rotating shafts 4 are symmetrically arranged around the central axis of the pedal 3. The bushings 5 engage with the rotating shafts 4 and are inserted into the adjustment holes 2. The fixing rods 6 are threaded to the inner wall of the rotating shafts 4. The connecting rods 7 are movably connected to the pedal 3. Next, through the frame 1, adjustment hole 2, pedal 3, rotating shaft 4, bushing 5, fixing rod 6, and connecting rod 7, the pedal 3 is adjusted to a suitable height according to the usage needs of users with different heights and leg lengths. Then, the bushing 5 is engaged with the pedal 3 and inserted into the adjustment hole 2 at the appropriate position. It is then fixed by the threaded fixing rod 6, allowing different users to use it in the most comfortable sitting posture, thereby avoiding excessive leg exertion, achieving the effect of saving effort and improving user comfort. At the same time, the smooth surface of the bushing 5 can reduce the friction between the pedal 3 and the frame 1, effectively improving the smoothness of pedal 3 braking and making it more practical.
[0017] Please see Figures 1-5 A labor-saving structure for a household sewing machine pedal is disclosed. A buckle 8 is installed on the outer wall of the pedal 3, and a limiting elastic rope 9 is installed on the inner wall of the buckle 8. The buckle 8 is slidably connected to the pedal 3, and the limiting elastic rope 9 is engaged with the buckle 8. Through the pedal 3, buckle 8, and limiting elastic rope 9, the limiting elastic rope 9 is engaged with the buckle 8. When using the machine, the user inserts both feet into the limiting elastic rope 9, while the buckle 8 and pedal 3 are slidably connected. This allows the user to adjust the distance between their feet to a suitable level. The limiting elastic rope 9 conforms to the instep and generates a certain elastic compressive force, preventing the feet from slipping off the pedal 3 when pedaling. This improves the stability of the connection between the feet and the pedal 3, avoiding the phenomenon of disengagement of force between the feet and the pedal 3 and loss of speed control.
[0018] Working principle: In use, first adjust pedal 3 to a suitable height according to the needs of users with different heights and leg lengths. Then, engage and connect bushing 5 to pedal 3, insert it into the appropriate adjustment hole 2, and secure it with threads using fixing rod 6. This allows different users to use the pedal in the most comfortable sitting posture, thus avoiding excessive leg exertion, achieving the effect of saving effort and improving user comfort. Simultaneously, the smooth surface of bushing 5 reduces friction between pedal 3 and frame 1, effectively improving the smoothness of pedal 3 braking and enhancing practicality. Then, insert both feet into the limiting spring rope 9, and simultaneously... The buckle 8 is slidably connected to the pedal 3, allowing the feet to be adjusted to a suitable distance. The limiting elastic rope 9 fits against the instep and generates a certain elastic squeezing force, preventing the feet from slipping off the pedal 3 when stepping on it. This improves the stability of the connection between the feet and the pedal 3, avoiding the phenomenon of the feet losing force from the pedal 3 and the speed control becoming uncontrollable. Finally, stepping on the pedal 3 causes it to rotate back and forth, and through the connecting rod 7, it drives the sewing machine to perform the sewing operation. This completes the use of the device. The contents not described in detail in this manual are existing technologies known to those skilled in the art.
