Furthermore, vibration during use can easily affect the use of the stator assembly, making stator assembly inconvenient to assemble, and the stator assembly is unstable and prone to loosening, thus affecting its use. Utility Model Content

[0005] The purpose of this invention is to provide a highly stable anti-loosening stator, which solves the problem that the stator in the prior art has poor operability during assembly and is prone to loosening, leading to instability.

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

[0007] A high-stability anti-loosening stator includes a housing with a ventilation mechanism on its surface and a stator assembly inside the housing. The stator assembly includes several circumferentially distributed assembly blocks.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-5 A highly stable, anti-loosening stator includes a housing 1. The surface of the housing 1 is provided with a ventilation mechanism 2. Inside the housing 1 is a stator assembly 3, which includes several circumferentially distributed assembly blocks 4. When the stator needs to be assembled, the assembly blocks 4 are arranged circumferentially and then pressed together to bring them closer together for assembly. One side of each assembly block 4 has a semi-circular protrusion 5, and the other side of each assembly block 4 has a semi-circular receiving groove 6. The protrusion 5 is located inside adjacent receiving grooves 6. When the stator assembly 3 needs to be formed using the assembly blocks 4, the protrusion 5 on the assembly block 4 needs to be placed into the receiving groove 6 on the adjacent assembly block 4. Several assembly blocks 4 form a circle, thereby... The assembly block 4 will not separate, ensuring the stability of the stator assembly 3 and preventing it from easily loosening and separating. An anti-movement groove 7 is provided on the outer side of the assembly block 4, and a T-shaped limiting part 8 is fixedly connected to the inner side of the assembly block 4. The space between the limiting parts 8 allows the coil to be wound conveniently, and prevents the coil from being damaged by high-intensity wear with the assembly block 4 during use. The anti-movement groove 7 allows the outer shell 1 to restrict the assembly block 4, further stabilizing the stator assembly 3 formed by the assembly block 4 and ensuring that the stator assembly 3 will not loosen and fall apart. A stabilizing mechanism 9 is provided on the outer side of the stator assembly 3, which can stabilize the stator assembly 3 from the outside, ensuring the integrity of the stator assembly 3 and enabling the stator assembly 3 to be used normally.

[0024] Furthermore, the ventilation mechanism 2 includes several exhaust slots 201 formed on the surface of the housing 1, heat dissipation holes 202 formed on the surface of the housing 1, and a ventilation cover 203 fixedly connected to one side of the housing 1. In use, the stator assembly 3 needs to be placed inside the housing 1. During this process, the exhaust slots 201 and heat dissipation holes 202 are used to facilitate smooth air exchange between the inside and outside of the housing 1, so as to facilitate heat dissipation of the stator assembly 3 and enable the stator assembly 3 to be used normally. The ventilation cover 203 can maintain air circulation without causing the stator assembly 3 to leave the inside of the housing 1.

[0025] Furthermore, several anti-movement blocks 10 are fixedly connected to the inner side of the outer casing 1, and fixed blocks 11 are fixedly connected to the surface of the outer casing 1. When the stator assembly 3 needs to be placed inside the outer casing 1, the stator assembly 3 can be stably placed inside the outer casing 1 by the auxiliary position restriction of the several anti-movement blocks 10, so that there will be no collision. The fixed blocks 11 are structures that can facilitate the fixing of the outer casing 1 to external facilities, and facilitate the use of the outer casing 1 and the internal stator assembly 3.

[0026] Furthermore, the stabilizing mechanism 9 includes a sleeve 901 fitted onto the outside of the stator assembly 3. Several semi-circular insertion blocks 902 are fixedly connected to the inner side of the sleeve 901. The insertion blocks 902 are located inside the adjacent anti-movement grooves 7. After the stator assembly 3 is assembled, the sleeve 901 is moved above the stator assembly 3 and then moved from top to bottom so that the sleeve 901 can fit onto the outside of the stator assembly 3. During this process, the insertion blocks 902 inside the sleeve 901 need to enter the adjacent anti-movement grooves 7 so that the stator assembly 3 cannot rotate inside the sleeve 901. The stability of the stator assembly 3 is improved by the sleeve 901 and the insertion blocks 902, ensuring the stable use of the stator assembly 3 and preventing loosening or separation.

[0027] Furthermore, several auxiliary plates 903 are fixedly connected to the surface of the sleeve 901. The auxiliary plates 903 facilitate the entry of the sleeve 901 and the stator assembly 3 into the housing 1. After entry, the auxiliary plates 903 and the anti-movement block 10 can restrict the position of the sleeve 901, ensuring that the stator assembly 3 will not shake inside the housing 1 and can be used stably.

[0028] Furthermore, several buffer pads 12 are fixedly connected inside the outer casing 1. The buffer pads 12 can reduce the collision between the inside of the outer casing 1 and the sleeve 901, reduce the vibration of the stator assembly 3 caused by the collision, and enable the stator assembly 3 to be used more stably without loosening, falling off or falling apart.

[0029] In summary:

[0030] When the stator is needed, it must first be assembled using several assembly blocks 4. During assembly, the protrusions 5 on the assembly blocks 4 can be inserted into the receiving grooves 6 on adjacent assembly blocks 4, so that several assembly blocks 4 are arranged in a circumferential distribution to form a stator assembly 3. Then, a sleeve 901 is fitted onto the outside of the stator assembly 3. The insertion block 902 on the inside of the sleeve 901 can enter the anti-movement groove 7 on the assembly block 4, thereby better stabilizing the stator assembly 3 through the sleeve 901, preventing the stator assembly 3 from loosening and falling apart, and ensuring the stability of the stator assembly 3. For proper use, the coil needs to be fitted onto the stator assembly 3 through the position between the two limiting parts 8. This reduces coil wear and allows the coil to function better. Then, the stator assembly 3 and the sleeve 901 are placed inside the outer casing 1. After entering the outer casing 1, the auxiliary plate 903 on the surface of the sleeve 901 cooperates with the anti-movement block 10 on the inner side of the outer casing 1, restricting the rotation of the sleeve 901. This ensures that the sleeve 901 is confined inside the outer casing 1, and any collision between the sleeve 901 and the outer casing 1 is mitigated by the buffer pad 12. The buffer pad 12 effectively reduces the vibration of the stator assembly 3 caused by the collision between the sleeve 901 and the outer casing 1 during use, ensuring the normal operation of the stator assembly 3. During use, the exhaust groove 201 and heat dissipation hole 202 allow air to circulate between the inside and outside of the outer casing 1, facilitating internal heat dissipation. The ventilation cover 203 ensures both ventilation and heat dissipation. The outer casing 1 can be fixed to the external wall by the fixing block 11, making it easy to determine the position of the outer casing 1 and the stator assembly 3. Through the above structure, when using the stator assembly 3, the buffer pad 12 effectively reduces the vibration of the outer casing 1 on the inside of the stator assembly 3, and also facilitates airflow exchange for heat dissipation. The reduced temperature and vibration extend the service life of the stator assembly 3. The assembly operability of the stator assembly 3 is significantly improved, reducing the possibility of coil wire damage during operation. It also restricts the stator assembly 3, ensuring stable operation and preventing it from loosening or falling apart, resulting in high stability of the stator assembly 3.
