Description

Technical Field

[0001] This utility model relates to a thread frame, specifically a sewing machine thread frame, and belongs to the field of sewing machine technology. Background Technology

[0002] A sewing machine is a mechanical tool that replaces hand sewing. A practical model was invented in 1846 by American Elias Howe. It uses the linkage of needle and thread to create lockstitch, chain stitch, and other stitches, significantly improving sewing efficiency. They are broadly classified into household and industrial types, with modern models including electric and intelligent numerical control systems. Widely used in clothing, home textiles, and leather goods, they have driven the industrialization of the textile industry, changed traditional production methods, and are an important piece of equipment in light industry.

[0003] A sewing machine thread holder is a component specifically designed to hold sewing thread spools. It typically consists of a support and a spool. The support is fixed to the wall or workbench, and the spool is mounted on the support. The sewing thread is then placed on the spool, which is usually tilted to allow gravity to keep the thread close to it, enhancing the stability of the spool and reducing the risk of thread slippage due to tension fluctuations during sewing. This ensures a smooth thread supply and is a practical design to prevent thread slippage.

[0004] When a sewing machine is running at high speed, the sewing thread is subjected to strong centrifugal force. The tilt angle is insufficient to counteract the outward offset force, making it easy for the sewing thread to break free from the spindle's constraint and fall off, affecting the continuity of thread supply. Simply setting a limit block on the spindle is inconvenient to operate. Therefore, a sewing machine thread holder is proposed here. Utility Model Content

[0005] This invention proposes a sewing machine thread holder that can quickly switch between a limited and non-limited state of the sewing thread, preventing the sewing thread from falling off.

[0006] This utility model is achieved through the following technical solution: a sewing machine thread frame, including a support component, the support component including a base plate, the base plate serving as a basic structure, providing stable support and bearing the weight of each component, the bottom of the base plate being equipped with casters, the casters being installed at the bottom of the base plate to improve the flexible movement capability of the base plate and facilitate adjustment of the working position.

[0007] It also includes a thread hanging component, which is mounted on a support component. The thread hanging component includes a vertical plate and a rotating shaft. The rotating shaft is mounted on the vertical plate and fixed to the vertical plate. The vertical plate is used to install the rotating shaft. A limit ring is fixed on the rotating shaft. The limit ring is used to support the bottom of the sewing thread. A label plate is fixed on the vertical plate. Labels can be pasted on the label plate to distinguish different sewing threads.

[0008] It also includes a limiting component, which is disposed on the rotating shaft. The limiting component includes a moving rod and a limiting plate. The limiting plate is movably disposed on the moving rod, and the moving rod has an installation groove. The limiting plate is rotatably connected to the installation groove by a torsion spring. When the limiting plate is inside the rotating shaft, the limiting plate is limited by the rotating shaft and is in a retracted state. At this time, the limiting plate is pressed against the rotating shaft by the elastic force of the torsion spring.

[0009] It also includes a linkage component, which is disposed on the rotating shaft and the moving rod. The linkage component is used to drive the moving rod to move. The linkage component includes a fixed ring, which is fixed to the inner side of the rotating shaft. A compression spring is fixed on the fixed ring, and a connecting ring is fixed on the compression spring. The connecting ring is fixed to the moving rod.

[0010] A metal strip is fixed on the connecting ring. The linkage component also includes a limiting hole, which is opened on the rotating shaft. The end of the metal strip away from the connecting ring extends into the limiting hole. The linkage component also includes a guide strip, which is fixed on the moving rod. The moving rod is slidably connected to the fixed ring through the guide strip. The guide strip can guide the moving rod so that the moving rod cannot rotate within the rotating shaft, and the metal strip and the limiting hole always remain aligned.

[0011] This utility model provides a sewing machine thread holder, which has the following beneficial effects:

[0012] 1. After the sewing thread is placed on the rotating shaft, the limiting hole is pressed. After the limiting hole moves into the rotating shaft, the connecting ring will drive the moving rod and the limiting plate to move under the action of the compression spring. After the limiting plate moves out of the rotating shaft, it will unfold under the action of the torsion spring, and then the sewing thread will be limited by the unfolded limiting plate.

[0013] 2. When the sewing machine thread holder is not in use, pressing the moving rod will cause the metal strip to move back into the limiting hole. At this time, the limiting plate is in the storage state, releasing the limitation on the sewing thread. This device can quickly switch the sewing thread between the limited state and the non-limited state, preventing the sewing thread from falling off. Attached Figure Description

The limiting component 3 includes a moving rod 301 and a limiting plate 302. The limiting plate 302 is movably mounted on the moving rod 301, and the moving rod 301 has an installation groove 303.

[0028] Please refer to this carefully. Figure 3 and Figure 4 The limiting plate 302 is rotatably connected to the mounting groove 303 by a torsion spring. When the limiting plate 302 is inside the rotating shaft 202, the limiting plate 302 is limited by the rotating shaft 202 and is in a retracted state. At this time, the limiting plate 302 is pressed against the rotating shaft 202 by the elastic force of the torsion spring.

[0029] Please refer to this carefully. Figure 3 and Figure 4 It also includes a linkage component 4, which is disposed on the rotating shaft 202 and the moving rod 301. The linkage component 4 is used to drive the moving rod 301 to move. The linkage component 4 includes a fixing ring 401, which is fixed inside the rotating shaft 202.

[0032] Working principle: After the sewing thread is sleeved on the rotating shaft 202, when it is necessary to limit the sewing thread, press the limiting hole 405. After the limiting hole 405 moves into the rotating shaft 202, under the action of the spring 402, the connecting ring 403 will drive the moving rod 301 and the limiting plate 302 to move. After the limiting plate 302 moves out of the rotating shaft 202, it will unfold under the action of the torsion spring. Then, the sewing thread is limited by the unfolded limiting plate 302 to prevent the sewing thread from falling off.

[0033] When not in use, press the moving rod 301, which will move the metal strip 404 back into the limiting hole 405. During this process, the limiting plate 302 will compress the torsion spring and gradually retract until it fits into the mounting groove 303 and is in a retracted state. At this time, the limitation on the sewing thread is released. This device can quickly switch between the limited state and the non-limited state of the sewing thread.
