[0002] Sewing machines are indispensable equipment in many fields such as garment manufacturing and home decoration. Their stable and efficient performance is directly related to production efficiency and product quality. As the power core of the sewing machine, the rational design of the motor's outer shell structure plays a crucial role in the installation, maintenance and overall performance of the motor.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: many motor housing interfaces do not have clear positioning marks or positioning structures, such as positioning pins or positioning holes. When assembling, it is difficult for operators to quickly and accurately align the various components, which can easily lead to misalignment. Once misaligned, it will not only affect the appearance quality of the motor, but may also cause vibration, noise and other problems during motor operation, and in severe cases, it may even damage the internal components of the motor.

Detailed Implementation

[0021] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0022] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a housing structure for a sewing machine motor, including a top shell 1; a bottom shell 2 is provided at the bottom of the top shell 1, and control columns 3 are fixedly connected to all four sides of the bottom of the bottom shell 2. An adjusting column 4 is rotatably connected inside the control column 3. A locking column 5 is slidably connected inside the adjusting column 4 through the inside of the top shell 1. Locking holes 6 are provided on both sides of the locking column 5. Arc blocks 7 are fixedly connected to both sides of the inside of the control column 3. Adjusting grooves 8 are provided on both sides of the adjusting column 4. Arc columns 9 are slidably connected inside the adjusting grooves 8. A locking rod 10 is fixedly connected to the side of the arc column 9 closest to the inside of the adjusting groove 8.

[0023] Using the above method: the worker merges and aligns the top shell 1 and the bottom shell 2, and inserts the locking pin 5 from the top of the top shell 1 into the interior of the adjusting pin 4. At the same time, the worker rotates the adjusting pin 4. As the adjusting pin 4 moves, it gradually drives the arc pin 9 to contact the thicker end of the arc block 7, so that the arc block 7 gradually pushes the arc pin 9 into the interior of the locking hole 6, locking the locking pin 5, thereby achieving the effect of merging and installing.

[0024] Reference Figure 2 and Figure 4 As shown, in this embodiment: the size of the locking rod 10 is adapted to the size of the locking hole 6, and the surface of the locking rod 10 is inserted into the interior of the locking hole 6;

[0025] With the above solution, when the locking rod 10 is fully inserted into the locking hole 6, the locking rod 10 can remain stable inside the locking hole 6 and is not easy to fall off because the size of the locking rod 10 is perfectly matched with the locking hole 6.

[0026] Reference Figure 4As shown in this embodiment: the control column 3 has two annular blocks 11 fixedly connected inside, and the outer diameter surface of the adjustment column 4 has two annular grooves 19.

[0027] The above scheme is adopted: the control column 3 is engaged with two annular blocks 11 and two annular grooves 19 on the outer diameter surface of the adjusting column 4. This design makes the adjusting column 4 more stable when rotating, and it is not easy to deviate or shake. The cooperation between the annular blocks 11 and the annular grooves 19 not only ensures the flexibility of the adjusting column 4 rotation, but also ensures its stability during operation, thereby improving the reliability and durability of the entire motor housing structure.

[0028] Reference Figure 4 As shown in this embodiment: a return spring 12 is fixedly connected to the side of the arc column 9 near the inside of the adjustment groove 8, and the side of the return spring 12 away from the arc column 9 is fixedly connected to the inside of the adjustment groove 8.

[0029] Using the above scheme: When the operator rotates the adjusting column 4 to gradually bring the arc column 9 into contact with the arc block 7, the arc block 7 gradually pushes the arc column 9 to compress and store the return spring 12, and drives the locking rod 10 to be inserted into the locking hole 6. When the operator rotates the adjusting column 4 to separate the arc column 9 from the arc block 7, under the action of the return spring 12, the locking rod 10 can slide out from the inside of the locking hole 6. At this time, the locking column 5 can be pulled out from the inside of the adjusting column 4, which makes it convenient for the operator to separate the top shell 1 from the bottom shell 2, thereby achieving the function of easy disassembly.

[0030] Reference Figure 4 and Figure 5 As shown in this embodiment: both ends of the adjusting column 4 are provided with grooves 13, and the inside of the grooves 13 is slidably connected with a rod 14. A return spring 15 is fixedly connected to the side of the rod 14 near the inside of the groove 13, and the side of the return spring 15 away from the rod 14 is fixedly connected to the inside of the groove 13. Both ends of the control column 3 are provided with holes 16.

[0031] Using the above solution: When the operator rotates the adjusting column 4 to adjust and drives the locking rod 10 into the locking hole 6, the insertion rod 14 is quickly inserted into the insertion hole 16 under the action of the return spring 15 through the setting between the groove 13 and the insertion hole 16, thus completing the limit of the adjusting column 4 and preventing the adjusting column 4 from rotating or shaking.

[0032] Reference Figure 4 As shown in this embodiment: sliding grooves 17 are provided on both sides of the inner side of the groove 13, and sliders 18 are fixedly connected to both sides of the insertion rod 14. The surface of the slider 18 is slidably connected to the inside of the sliding groove 17.

[0033] By adopting the above solution, the stability of the insertion rod 14 sliding inside the groove 13 is increased by setting the groove 17 and the slider 18, avoiding the insertion rod 14 from deviating or getting stuck during the movement, and further improving the stability of the adjustment column 4 limit.

[0034] Reference Figure 4 As shown in this embodiment: guide grooves 20 are provided at both ends of the adjustment groove 8, and guide blocks 21 are fixedly connected to both ends of the arc column 9. The surface of the guide block 21 is slidably connected to the inside of the guide groove 20.

[0035] The above solution guides and limits the movement trajectory of the arc column 9 by means of the guide groove 20 and the guide block 21, so that the arc column 9 can slide smoothly along the inside of the guide groove 20, avoiding the arc column 9 from deviating or shaking during movement, thereby further improving the stability of the locking rod 10.

[0036] Working principle: The operator merges and aligns the top shell 1 and the bottom shell 2, and inserts the locking pin 5 from the top of the top shell 1 into the interior of the adjusting pin 4. At the same time, the operator rotates the adjusting pin 4. As the adjusting pin 4 moves, it gradually drives the arc pin 9 to contact the thicker end of the arc block 7, so that the arc block 7 gradually pushes the arc pin 9 into the interior of the locking hole 6, locking the locking pin 5, thereby achieving the function of merging and installing.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
