Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor accessories, specifically a motor rivet anti-loosening locking structure. Background Technology
[0002] The self-riveting ferrules of the aquarium submersible pump motor core are a component of the motor core. The motor core is generally made of stacked silicon steel sheets, and the self-riveting ferrules are specially designed for automatic riveting and fixing. Their shape is similar to ordinary silicon steel sheets, but they usually have protrusions, recesses, or special structures at the edges or specific locations. These structures can interlock during the stacking process of the motor core or achieve self-riveting through certain processes (such as stamping). During motor operation, the core is subjected to various forces, including electromagnetic forces. The self-riveting ferrules firmly fix the silicon steel sheets together, preventing them from loosening or shifting under vibration or other external forces, thus ensuring the integrity and stability of the motor core.
[0003] However, through our long-term observation, we have found that the motors mentioned above will vibrate during operation; aquarium submersible pumps may also be affected by external factors such as water flow impact and fluctuations. These vibrations and impacts will be transmitted to the motor core, causing damage to the fixing structure of the self-rivet plates and resulting in loosening. Therefore, there is an urgent need for a motor rivet anti-loosening locking structure to solve the above defects. Utility Model Content
[0004] The purpose of this utility model is to provide a motor rivet anti-loosening locking structure to solve the defects mentioned in the background art.
[0005] To achieve the above objectives, a motor rivet anti-loosening locking structure is provided, including an anti-loosening locking assembly. The anti-loosening locking assembly is installed on the motor rivet body, and the motor rivet body and the motor core are fixedly connected by the anti-loosening locking assembly. Slots are provided on both sides of the surface of the motor rivet body. The anti-loosening locking assembly includes four sets of first holes and second holes respectively opened in the two sets of slots. Studs are inserted into the first holes and second holes. At the same time, the studs pass through the side wall of the motor rivet body and the motor core and are screwed and fixed to the lower nut and upper nut respectively.
[0006] Preferably, the motor rivet body is a "U"-shaped structure made of metal, and both sides of the bottom of the motor rivet body are provided with receiving grooves with an arc-shaped cross-section.
[0007] Preferably, the studs are evenly arranged in four groups, and the distance between adjacent groups of studs is the same. At the same time, the four groups of studs are arranged in parallel, and a circular blocking plate is fixedly provided at the end of each stud.
[0008] Preferably, the inside of the slot is covered with a limit seat, and limit pieces are fixedly installed at the corners of the limit seat. At the same time, mounting holes are provided inside the four limit pieces.
[0009] Preferably, stud bolts are inserted into the four mounting holes. The four limit pieces are circularly arranged. At the same time, four strip holes are evenly provided on the surface of the limit seat.
[0010] Preferably, the limit seat is in a "mouth" shape made of metal material. The four stud bolts are connected together through the limit seat. At the same time, the four stud bolts have the same specification and model.
[0011] Compared with the prior art, the beneficial effect of the utility model is that the stud bolts pass through the side wall of the motor rivet piece body and the motor iron core and are respectively screwed and fixed with the lower nut and the upper nut, so that the motor rivet piece body and the motor cell can be fixedly connected, avoiding loosening between the motor rivet piece body and the motor cell, effectively preventing loosening between the rivet piece and the motor cell due to factors such as motor vibration and temperature change, ensuring the stability of the connection between the two, thus ensuring the normal operation of the motor and reducing the failures caused by connection loosening.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] Please refer to Figure 1-4This utility model provides a motor rivet anti-loosening locking structure, including an anti-loosening locking component 3. The anti-loosening locking component 3 is installed on the motor rivet body 1, and the motor rivet body 1 and the motor core are fixedly connected by the anti-loosening locking component 3. The motor rivet body 1 has slots 2 on both sides of its surface. The anti-loosening locking component 3 includes four sets of first holes 31 and second holes 32 respectively opened in the two sets of slots 2. The first holes 31 and second holes 32 are inserted into the interior of the first holes 31 and second holes 32. At the same time, the studs 34 pass through the side wall of the motor rivet body 1 and the motor core and are screwed and fixed to the lower nut 38 and the upper nut 39 respectively.
[0018] Working Principle: In actual use, the motor rivet body 1 and the motor core are fixedly connected by the anti-loosening locking assembly 3. Specifically, the stud 34 passes through the side wall of the motor rivet body 1 and the motor core and is screwed to the lower nut 38 and the upper nut 39 respectively. This fixed connection between the motor rivet body 1 and the motor core prevents loosening and effectively prevents loosening due to motor vibration, temperature changes, etc., ensuring the stability of the connection and thus guaranteeing the normal operation of the motor and reducing malfunctions caused by loose connections. The stable connection between the rivet and the motor core helps maintain the uniformity and stability of the internal magnetic field of the motor, thereby improving the motor's performance, such as the smoothness of the output torque and the stability of the speed. This allows the motor to work more stably under different operating conditions and reduces performance fluctuations caused by magnetic field changes due to loose connections.

[0020] The studs 34 are evenly arranged in four groups, and the distance between two adjacent groups of studs 34 is the same. At the same time, the four groups of studs 34 are arranged in parallel, and a circular blocking plate 33 is fixedly provided at the end of each stud 34.
[0021] In a preferred embodiment, the inside of the slot 2 is covered by a limiting seat 35, and limiting pieces 36 are fixedly installed at the corners of the limiting seat 35. At the same time, the inside of each of the four sets of limiting pieces 36 is provided with mounting holes 37.
[0022] Each of the four sets of mounting holes 37 has a stud 34 inserted inside, and all four sets of limiting pieces 36 are circular. At the same time, the surface of the limiting seat 35 is evenly provided with four sets of strip holes.
