[0004] Existing motors, such as those mentioned above, often achieve good quiet operation by combining a soundproof enclosure with optimized internal electromagnetic design. However, in practice, these motors are usually connected to an external power source via a power cord. The long power cord, suspended on the outside, can affect the installation and stable operation of the soundproof enclosure. Therefore, there is an urgent need to develop a suitable motor to address these issues. Summary of the Invention

[0005] The purpose of this utility model is to provide a motor with good noise reduction in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quiet motor includes a soundproof housing, a sleeve fixedly connected to the rear end face of the soundproof housing, a notch and a retainer respectively opened on both sides of the vertical end of the sleeve, a positioning component for cable positioning is provided inside the retainer, and a winding plate is fixedly connected to the rear end face of the sleeve, and the cross-section of the winding plate is T-shaped.

[0008] Preferably, a locking rod is provided inside the winding plate, and the outer wall of the locking rod is screwed into the inner wall of the soundproof shell.

[0009] Preferably, a rectangular block is fixedly connected to the front end face of the housing, the outer wall of the rectangular block engages with the inner wall of the soundproof housing through a slot, and the outer wall of the locking rod passes through the interior of the rectangular block.

[0010] Preferably, the rectangular block is integrally formed with the outer wall of the casing.

[0011] Preferably, the positioning component includes a push rod that is screwed into the inner wall of the card holder, and the open end of the push rod is rotatably connected to a limit block.

[0012] Preferably, the limiting block is wrapped with a rubber pad on its outer side.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the soundproof housing ensures the motor's quiet operation. The cable is passed through the notch and the card holder and then connected to the external power supply. The excess cable is then wound around the winding disc. The push rod is rotated to engage with the inner wall of the card holder. The push rod pushes the limiting block to contact the outer wall of the cable, thus achieving cable storage. The limiting block, in conjunction with the inside of the card holder, positions the cable at this location. This prevents the coiled cable from coming loose. When the cable is subjected to external traction, the force is applied to the connection between the cable and the card holder, rather than being directly transmitted to the connection between the cable and the motor, thereby improving the stability of the motor with good quiet operation.

[0015] 2. In this application, the rectangular block is inserted into the slot. After the locking rod passes through the winding disc and the rectangular block, it is screwed onto the inner surface of the soundproof shell. This achieves the fixation of the shell and the soundproof shell, ensuring the convenience of shell assembly and disassembly. At the same time, the cooperation between the rectangular block and the slot can prevent the locking rod from becoming loose due to the coaxiality of the locking rod, the shell and the soundproof shell.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4. This utility model provides a technical solution:

[0024] A quiet motor includes a soundproof housing 1, a sleeve 2 fixedly connected to the rear end face of the soundproof housing 1, a notch 5 and a card seat 6 respectively opened on both sides of the vertical end of the sleeve 2, a positioning component for cable positioning is provided inside the card seat 6, and a winding plate 4 is fixedly connected to the rear end face of the sleeve 2, and the cross-section of the winding plate 4 is T-shaped.

[0025] The soundproof housing 1 ensures the motor's quiet operation. After the cable passes through the notch 5 and the card holder 6, it is connected to the external power supply. Then, the excess part of the cable is wound around the winding plate 4. The push rod 7 is rotated to make it screw into the inner wall of the card holder 6. The push rod 7 pushes the limiting block 8 to contact the outer wall of the cable, thus realizing the cable storage. The limiting block 8 works with the inside of the card holder 6 to position the cable at this point. This can prevent the coiled cable from coming loose. When the cable is subjected to external traction, the force will be applied to the connection between the cable and the card holder 6, rather than directly transmitted to the connection between the cable and the motor, thereby improving the stability of the motor with good quiet operation.

[0026] It should be noted that the soundproof housing 1, combined with the internal electromagnetic technology optimization, can provide a good noise reduction effect for the motor. This technology is quite common in existing technologies and will not be elaborated here.

[0027] Specifically, as shown in Figures 2 and 4, a locking rod 9 is inserted inside the connecting plate 4, and the outer wall of the locking rod 9 is screwed into the inner wall of the soundproof shell 1. A rectangular block 10 is fixedly connected to the front end of the shell 2. The outer wall of the rectangular block 10 is engaged with the inner wall of the soundproof shell 1 through the slot 3, and the outer wall of the locking rod 9 passes through the inside of the rectangular block 10. The rectangular block 10 is inserted into the slot 3. After the locking rod 9 passes through the connecting plate 4 and the rectangular block 10, it is screwed into the inner wall of the soundproof shell 1. This achieves the fixation of the shell 2 and the soundproof shell 1, ensuring the convenience of disassembling and assembling the shell 2. At the same time, the cooperation between the rectangular block 10 and the slot 3 can prevent the locking rod 9 from easily becoming loose due to the coaxiality of the locking rod 9, the shell 2 and the soundproof shell 1.

[0028] Specifically, as shown in Figures 2 and 3, the rectangular block 10 and the outer wall of the housing 2 are integrally formed to ensure the connection strength between the two. The positioning component includes a push rod 7 that is screwed into the inner wall of the card seat 6. The open end of the push rod 7 is rotatably connected to a limit block 8. Rotating the push rod 7 causes it to screw into the inner wall of the card seat 6. The push rod 7 pushes the limit block 8 to contact the outer wall of the cable. The outer side of the limit block 8 is covered with a rubber pad to avoid the limit block 8 from damaging the outer sheath of the cable.

[0029] Working principle: The soundproof housing 1 ensures the motor operates quietly. After passing the cable through the notch 5 and the holder 6, it is connected to the external power supply. Then, the excess cable is wound around the winding disc 4. Rotating the push rod 7 causes it to engage with the inner wall of the holder 6. The push rod 7 pushes the limiting block 8 to contact the outer wall of the cable, thus achieving cable storage. The limiting block 8, in conjunction with the inside of the holder 6, positions the cable at this location, preventing the wound cable from becoming loose. When the cable is subjected to external traction, the force acts on the cable and the holder. The connection of seat 6 is not directly transmitted to the connection of the cable and the motor, thereby improving the stability of the motor with good noise reduction. The rectangular block 10 is inserted into the slot 3. After the locking rod 9 passes through the connecting plate 4 and the rectangular block 10, it is screwed into the inner wall of the soundproof shell 1 to fix the shell 2 and the soundproof shell 1. This ensures the convenience of disassembling and assembling the shell 2. At the same time, the cooperation between the rectangular block 10 and the slot 3 can prevent the locking rod 9 from easily becoming loose due to the coaxiality of the locking rod 9, the shell 2 and the soundproof shell 1.

[0030] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
