Description

Technical Field

[0001] This utility model relates to the field of sewing equipment technology, and in particular to a sewing machine table adjustment device. Background Technology

[0002] As core equipment in garment processing and home textile production, sewing machines rely heavily on their worktables for smooth sewing operations. The core function of these worktables is to provide a stable mounting surface for the sewing machine and a convenient operating platform for the user, ensuring the machine doesn't easily shift during high-speed operation. They also facilitate the user's laying out, positioning, and sewing of the fabric. With the textile industry's increasing demands for production efficiency and operational comfort, the practicality, flexibility, and stability of sewing machine worktables have become key factors influencing the overall production experience. While various sewing machine worktables on the market meet basic support requirements, there is still room for functional optimization in practical applications.

[0003] Existing sewing machine table devices have limitations in terms of angle adjustment flexibility. Traditional sewing machine tables mostly adopt an integrated fixed structure, and the tilt angle of the table and the sewing machine body cannot be adjusted. Users must passively adapt to a fixed operating angle, which can easily cause neck and back fatigue due to discomfort after long-term use. Even if some devices are designed to be adjustable, they mostly rely on manual knobs, screws, or snap-on structures to achieve angle adjustment. The adjustment process requires manual force and is difficult to control the angle precisely, making the operation cumbersome and inefficient. It cannot adapt to the personalized needs of users with different heights and operating habits, thus affecting the comfort and work efficiency of sewing operations. To address these issues, a sewing machine table adjustment device is provided. Utility Model Content

In the description of this utility model, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0021] Reference Figures 1 to 5 In this embodiment of the utility model, a sewing machine table adjustment device includes: Sewing machine body 3; Tabletop angle control mechanism 2 is located below the sewing machine body 3. The tabletop angle control mechanism 2 is used to adjust the tilt angle of the sewing machine body 3, so that the user can better observe and use the sewing machine body 3. Support table 1 is provided below the sewing machine body 3. Support table 1 is used to support the table angle control mechanism 2 and facilitate its movement.

[0022] The above solution is adopted: the support table 1 first provides stable support for the table angle control mechanism 2 located above it, ensuring that the table angle control mechanism 2 will not shake during operation; when the user needs to adjust the tilt angle of the sewing machine body 3 to obtain a better viewing and usage angle, the table angle control mechanism 2 is activated, and the table angle control mechanism 2 changes the tilt state of the sewing machine body 3 through its own adjustment action, thereby meeting the different usage needs of the user.

[0023] The tabletop angle control mechanism 2 includes a lower support plate 21, an upper support plate 22 above the lower support plate 21, an adjustment mechanism 23 and an auxiliary support mechanism 24 above the lower support plate 21, and upper drawer slots 25 fixedly connected above the lower support plate 21 and below the upper support plate 22. The lower support plate 21 and the upper support plate 22 are initially parallel to each other and are rotatably connected by a rotating seat. The adjustment mechanism 23 and the auxiliary support mechanism 24 are located above the lower support plate 21.

[0024] Using the above scheme: In the initial state, the lower support plate 21 and the upper support plate 22 are parallel to each other and are rotatably connected by a rotating seat, which can maintain a stable relative position; when it is necessary to adjust the tilt angle of the sewing machine body 3, the adjustment mechanism 23 starts to work, and through its own structural action, it drives the upper support plate 22 to rotate around the rotating seat between the lower support plate 21 and the upper support plate 22, thereby changing the tilt angle of the upper support plate 22; during the process of the adjustment mechanism 23 driving the upper support plate 22 to rotate, the auxiliary support mechanism 24 plays a role simultaneously, providing auxiliary support for the upper support plate 22 during the rotation process, and preventing the upper support plate 22 from shaking due to uneven force.

[0025] The support platform 1 includes a lower support platform 11, four sets of casters 12 are fixedly connected to the bottom of the lower support platform 11, and a lower drawer slot 13 is fixedly connected to the inner side of the lower support platform 11. Multiple sets of sliding drawers are provided inside the lower drawer slot 13.

[0026] With the above solution, when the entire sewing machine table adjustment device needs to be moved, the four sets of universal wheels 12 fixedly connected to the lower support 11 can roll flexibly, reducing the friction when the device moves, so that the user can easily push the device to the designated position.

[0027] The adjusting mechanism 23 includes a fixed seat 231 fixedly connected to the upper part of the lower support plate 21. A long threaded rod 232 is rotatably connected to the inner side of the fixed seat 231. A drive motor 233 is fixedly connected to the upper part of the lower support plate 21 on the side of the fixed seat 231. The rotating shaft of the drive motor 233 passes through the fixed seat 231 and is fixedly connected to the long threaded rod 232. A threaded through hole adapted to the long threaded rod 232 is opened on the inner side of the sliding block 234. The sliding block 234 is slidably connected to the upper part of the fixed seat 231. A first rotating seat 235 is fixedly connected to the lower part of the 2, and a second rotating seat 236 is fixedly connected to the upper part of the lower support plate 21. A first rotating arm 237 is rotatably connected to the lower part of the first rotating seat 235, and a second rotating arm 238 is rotatably connected to the upper part of the second rotating seat 236. The two ends of the second rotating arm 238 are rotatably connected to the inner side of the second rotating seat 236 and the inner side of the first rotating arm 237, respectively. The two ends of the first rotating arm 237 are rotatably connected to the inner side of the first rotating seat 235 and the outer side of the sliding block 234, respectively.

[0028] Using the above scheme: When it is necessary to adjust the angle of the upper support plate 22 through the adjustment mechanism 23, the drive motor 233 fixed above the lower support plate 21 is started. The rotating shaft of the drive motor 233 will drive the long threaded rod 232 fixedly connected to it to rotate inside the fixed seat 231 (because the long threaded rod 232 is rotatably connected to the inside of the fixed seat 231). Since the sliding block 234 has a threaded through hole that matches the long threaded rod 232 on its inner side, and the sliding block 234 is slidably connected to the top of the fixed seat 231, the rotation of the long threaded rod 232 will be converted into the sliding block 234 sliding linearly along the top of the fixed seat 231. When the sliding block 234 slides, it will drive one end of the first rotating arm 237 rotatably connected to its outer side to slide synchronously. The first rotating arm 237 moves, and the other end of the first rotating arm 237 is rotatably connected to the inner side of the first rotating seat 235 fixed below the upper support plate 22. At the same time, the inner side of the first rotating arm 237 is also rotatably connected to one end of the second rotating arm 238, and the other end of the second rotating arm 238 is rotatably connected to the inner side of the second rotating seat 236 fixed above the lower support plate 21. Therefore, the movement of the first rotating arm 237 will drive the second rotating arm 238 to rotate around the second rotating seat 236. Through the linkage of the first rotating arm 237 and the second rotating arm 238, the upper support plate 22 is finally pushed to rotate around the rotating seat between it and the lower support plate 21, thereby adjusting the tilt angle of the upper support plate 22 and thus adjusting the tilt angle of the sewing machine body 3.

[0029] The auxiliary support mechanism 24 includes a third rotating seat 241 fixedly connected to the lower part of the upper support plate 22. A hollow tube 242 is rotatably connected to the lower part of the third rotating seat 241. An expansion port 243 is opened at the lower part of the hollow tube 242. A fastening threaded ring 244 is provided on the outer side of the hollow tube 242. External threads that are compatible with the fastening threaded ring 244 are opened on the outer side of the hollow tube 242 and the expansion port 243. A fourth rotating seat 245 is fixedly connected to the upper part of the lower support plate 21. A solid slide rod 246 is rotatably connected to the upper part of the fourth rotating seat 245. The end of the solid slide rod 246 slides inside the hollow tube 242.

[0030] Using the above scheme: When the adjusting mechanism 23 drives the upper support plate 22 to rotate around the rotating seat between it and the lower support plate 21, the third rotating seat 241 fixed below the upper support plate 22 will move synchronously with the upper support plate 22, and the hollow tube 242 rotatably connected below the third rotating seat 241 will also change position accordingly; since a solid sliding rod 246 is rotatably connected above the fourth rotating seat 245 fixed above the lower support plate 21, and the end of the solid sliding rod 246 slides inside the hollow tube 242, the change in position of the hollow tube 242 will cause the solid sliding rod 246 to slide along the inside of the hollow tube 242, and at the same time, the solid sliding rod 246 will rotate around the fourth rotating seat 245, thereby adapting to the upper support plate 22. The angle change prevents the auxiliary support mechanism 24 from obstructing the adjustment of the upper support plate 22. When the angle of the upper support plate 22 is adjusted to the correct position, the fastening threaded ring 244 on the outside of the hollow tube 242 is rotated. Since the hollow tube 242 and the expansion port 243 have external threads that are compatible with the fastening threaded ring 244, the fastening threaded ring 244 will move downward along the external threads and squeeze the expansion port 243, causing the expansion port 243 to contract and tightly fit the outside of the solid slide rod 246, thereby fixing the relative position of the hollow tube 242 and the solid slide rod 246. At this time, the auxiliary support mechanism 24 will provide stable support for the upper support plate 22 and prevent the upper support plate 22 from shifting its angle when bearing the sewing machine body 3.

[0031] The working principle of this utility model is as follows: When in use, the entire device is first pushed to a suitable working position by the four sets of universal wheels 12 under the lower support platform 11 of the support platform 1. The lower support platform 11 provides stable support for the upper platform angle control mechanism 2. At the same time, the tools or accessories required for the sewing machine can be stored through the sliding drawer in the lower drawer slot 13 inside the lower support platform 11 and the upper drawer slot 25 above the lower support plate 21 and below the upper support plate 22 in the platform angle control mechanism 2, so as to prepare for operation. When it is necessary to adjust the tilt angle of the sewing machine body 3 to obtain a more comfortable operating view, the adjustment mechanism 23 of the table angle control mechanism 2 is activated: the drive motor 233 above the lower support plate 21 starts to run, and its rotating shaft drives the long threaded rod 232 inside the fixed seat 231 to rotate synchronously. Since the sliding block 234 has a threaded through hole that matches the long threaded rod 232 and is slidably connected to the upper part of the fixed seat 231, the rotation of the long threaded rod 232 is converted into the sliding block 234 sliding linearly along the fixed seat 231; the sliding block 234 drives one end of the first rotating arm 237, which is rotatably connected to it, to move. The other end of the first rotating arm 237 is rotatably connected to the first rotating seat 235 below the upper support plate 22. At the same time, the inner side of the first rotating arm 237 is rotatably connected to one end of the second rotating arm 238. The other end of the second rotating arm 238 is rotatably connected to the second rotating seat 236 above the lower support plate 21. Through the linkage of the two, the upper support plate 22 is pushed to rotate around the rotating seat between it and the lower support plate 21, so as to realize the adjustment of the tilt angle of the sewing machine body 3. After the angle is adjusted to the correct position, the auxiliary support mechanism 24 is used for stabilization: during the rotation of the upper support plate 22, the third rotating seat 241 below it drives the hollow tube 242 to move synchronously, and the solid slide rod 246 connected to the fourth rotating seat 245 above the lower support plate 21 slides along the inner side of the hollow tube 242 and swings upward to adapt to the angle change; at this time, the fastening threaded ring 244 on the outer side of the hollow tube 242 is rotated, so that it moves downward along the external thread and squeezes the expansion port 243, causing the expansion port 243 to shrink and tightly fit the solid slide rod 246, fixing the relative position of the two, forming a stable support, preventing the upper support plate 22 from shifting angle when bearing the sewing machine body 3, and ensuring the stability of the operation process.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
