[0003] A search of patent application number CN201821375736.7 reveals a sewing machine frame, relating to the field of sewing machine technology. The advantages of this utility model are: the height of the sewing machine frame can be adjusted according to the user's needs, meeting the user's height requirements; it has strong stability, provides cushioning, reduces shaking caused by sewing, increases sewing quality, and reduces the user's labor intensity. Currently, because existing sewing machines vary in size, the frame cannot be adjusted in size and support according to the machine's volume, resulting in insufficient functionality and inconvenience.

[0004] Further searching patent application number CN202322841264.7 reveals that this utility model belongs to the field of sewing machine technology, specifically a sewing machine frame. It solves the problems of existing technologies where, after folding and storing, the overall storage space occupied by the sewing machine frame is still large, making storage and transportation inconvenient; furthermore, because the extended and thickened plates are connected by screws, the screws still need to be installed or removed during assembly and disassembly, making the operation cumbersome and inconvenient; and because existing sewing machines vary in size, the frame cannot adjust its size and support force according to the machine's volume, resulting in insufficient functionality and inconvenience in use. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a multifunctional adjustable sewing machine frame. Rotation of a threaded rod causes a moving rod and a circular block to move. The movement of the moving rod pushes a push plate, which in turn moves a second support bracket while the first support bracket remains stationary, maintaining a certain distance between them. As the second support bracket continues to move, the first support bracket moves along with it. The movement of the circular block causes both the first and second vertical supports to move simultaneously. Subsequent manual operation allows for the movement of the second vertical support bracket while the first vertical support bracket remains stationary, enabling adjustment of the spacing. This adjustment of the second and second vertical supports allows for adaptation to larger sewing machines. The adjustment of the first and second vertical supports increases the supporting force, facilitating the support of larger sewing machines. This enhances the functionality of the frame, making it convenient to use. It solves the problem that existing frames cannot adjust their size and supporting force according to the size of different sewing machines, resulting in insufficient functionality and inconvenience.

[0015] This invention provides a multifunctional adjustable sewing machine frame. Compared with the prior art, it has the following advantages: 1. This multi-functional adjustable sewing machine frame uses the rotation of a threaded rod to move a moving rod and a circular block. The movement of the moving rod pushes a push plate, causing the second support bracket to move first while the first support bracket remains stationary, maintaining a certain distance between them. As the second support bracket continues to move, the first support bracket moves along with it. The movement of the circular block causes the first and second vertical supports to move simultaneously. Subsequently, manual operation allows the second vertical support bracket to move while the first vertical support bracket remains stationary, enabling the adjustment of the distance between them. This adjustment of the second and second support brackets allows for the adaptation to larger sewing machines, while the adjustment of the first vertical support bracket and the first support bracket increases the supporting force, facilitating the support of larger sewing machines, thus enhancing the functionality of the frame and making it easy to use.

[0016] 2. This multi-functional adjustable sewing machine frame moves the connecting rod and the reinforcing plate by moving the second vertical support. After the reinforcing plate comes into contact with the magnet on the other side of the first vertical support, the stability of the second vertical support is improved because the reinforcing plate is made of iron.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2 In accordance with 4-5, this utility model provides a technical solution: a multifunctional adjustable sewing machine frame, including a fixed bracket 1, an adjustment mechanism 2 provided below the fixed bracket 1, a crossbar 4 fixedly provided at the top of the fixed bracket 1, and a fixed support plate 3 fixedly provided at the bottom of the fixed bracket 1.

[0021] The adjusting mechanism 2 includes a rotating rod 201, with threaded rods 202 fixedly installed at both ends of the rotating rod 201. A moving rod 203 is installed at the end of the threaded rod 202 away from the rotating rod 201, and the moving rod 203 is threadedly connected to the threaded rod 202. A push plate 204 is installed at the end of the moving rod 203 away from the threaded rod 202. The push plate 204 has a U-shaped cross-section. A first support bracket 205 is installed at one end of the push plate 204. A second support bracket 206 is fixedly installed on the side of the first support bracket 205 away from the push plate 204. The push plate 204 passes through the first support bracket 205. A variable rod 207 is installed on both sides of the moving rod 203. A first vertical bracket 208 is installed at the end of the variable rod 207 away from the moving rod 203. A second vertical bracket 209 is installed on one side of the first vertical bracket 208.

[0022] There are multiple fixed support plates 3, and the rotating rod 201 passes through one fixed support plate 3 and is rotatably connected to one fixed support plate 3.

[0023] Both ends of the variable rod 207 are provided with circular blocks 214. One circular block 214 at one end of the variable rod 207 is fixedly connected to the first vertical support 208, and the other circular block 214 at the other end of the variable rod 207 is fixedly connected to the moving rod 203. The variable rod 207 is inclined. Both ends of the variable rod 207 are rotatably connected to the circular blocks 214. When the first circular block 214 moves, it drives one end of the variable rod 207. Since the variable rod 207 is rotatably connected to the corresponding circular blocks 214 at both ends, by moving one end of the variable rod 207, the variable rod 207 can change from an inclined state to a horizontal state, and push the second vertical support 209 and the first vertical support 208 to move simultaneously, which can increase the spacing.

[0024] Both ends of the fixed bracket 1 and the crossbeam 4 are slidably provided with sliding rods 5, and the sliding rods 5 are fixedly connected to the corresponding first support bracket 205 and first vertical bracket 208. The sliding rods 5 can move simultaneously by moving the first support bracket 205 and the first vertical bracket 208.

[0025] Please see Figure 2-4 The top and bottom surfaces of the first vertical support 208 are inlaid with magnets 210. The top and bottom surfaces of the second vertical support 209 near the magnets 210 are inlaid with iron sheets 211. A connecting rod 212 is fixedly installed at one end of the iron sheet 211. The connecting rod 212 passes through the magnets 210 and the first vertical support 208, and is slidably connected to the magnets 210 and the first vertical support 208. A reinforcing plate 213 is fixedly installed at the other end of the connecting rod 212 away from the iron sheet 211. The reinforcing plate 213 is made of iron. When the first vertical support... When the support 208 is not moving, the second vertical support 209 is moved to separate the iron plate 211 at the second vertical support 209 from the magnet 210, thus increasing the distance between the first vertical support 208 and the second vertical support 209. This allows for the adaptation to larger sewing machines. Furthermore, the movement of the second vertical support 209 drives the movement of the connecting rod 212 and the reinforcing plate 213. Subsequently, the reinforcing plate 213 is brought into contact with the magnet 210 on the other side of the first vertical support 208. Because the reinforcing plate 213 is made of iron, it improves the stability of the second vertical support 209.

[0026] During operation, the sewing machine is placed on the support frame, which provides support for the machine. If the sewing machine is large, rotating the rotating rod 201 causes the threaded rods 202 on both sides to rotate. Since the threaded rods 202 are threadedly connected to the moving rods 203, the rotation of the threaded rods 202 causes the moving rods 203 to move, reducing the distance between the two moving rods 203. When the moving rods 203 move, a circular block 214 connected to the moving rods 203 moves simultaneously, and the push plate 204 at the end of the moving rods 203 moves at the same time. The movement of the push plate 204 pushes the second support bracket 206. The movement of the push plate 204 increases the distance between the first support bracket 205 and the second support bracket 206, facilitating subsequent adaptation to different sewing machine sizes. Because the push plate 204 penetrates and contacts the first support bracket 205, it allows the second support bracket 206 to move first. During the movement of the push plate 204, it eventually comes into contact with the first support bracket 205. After contact, the continued movement of the push plate 204 causes the first support bracket 205 to move simultaneously. At this point, the first and second support brackets move concurrently, allowing for adjustment of the support point spacing. This adjusts the overall support force. When the first circular block 214 moves, it drives one end of the variable rod 207. Since the variable rod 207 is rotatably connected to the corresponding circular blocks 214 at both ends, moving one end of the variable rod 207 allows it to change from an inclined state to a horizontal state, and pushes the second vertical support 209 and the first vertical support 208 to move simultaneously, increasing the distance between them. When the first vertical support 208 stops moving, the second vertical support 209 is moved, causing the iron plate 211 at the second vertical support 209 to separate from the magnet 210, thus separating the first vertical support 208 and the second vertical support 209. The distance between the two supports is separated to accommodate larger sewing machines. The movement of the second vertical support 209 drives the movement of the connecting rod 212 and the reinforcing plate 213. Subsequently, the reinforcing plate 213 is brought into contact with the magnet 210 on the other side of the first vertical support 208. Because the reinforcing plate 213 is made of iron, it can improve the stability of the second vertical support 209. This allows it to accommodate sewing machines of different sizes when the second support support 206 and the second vertical support 209 are adjusted. The adjustment of the first support support 205 and the first vertical support 208 can support larger sewing machines, making it convenient to support larger sewing machines and easy to use.
