Description

Technical Field

[0001] This utility model relates to the field of shaded-pole motor technology, and in particular to a shaded-pole motor for a juicer. Background Technology

[0002] A shaded-pole motor is a special type of single-phase AC induction motor, often used in low-power applications such as small household appliances and commercial equipment. Shaded-pole motors used in juicers are typically used in applications requiring low power and high speed.

[0003] The stator consists of a stator core, coils, rotor, main shaft, bearings, and upper and lower housings. When the rotor's position needs to be restricted, the rotor is first inserted into the hole opened in the stator core, and then the upper and lower housings are respectively placed at both ends of the rotor and fixed together with bolts. The rotor's position is restricted by the housings that are fixed in position. However, during long-term use, the bolts may loosen due to the vibration generated by the motor, resulting in the rotor's position being unable to be fixed. Utility Model Content

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-4 The illustrated shaded-pole motor for a juicer includes a motor body 1, an upper shell 2 at the top of the motor body 1, and a lower shell 3 at the bottom of the motor body 1. Bolts 5 are symmetrically arranged on both sides of the upper shell 2 to fix the position between the upper shell 2 and the lower shell 3. A nut 4 is fixedly connected to the bottom end of the lower shell 3. The motor also includes:

[0024] The limiting component 6 is used to limit the movement of the bolt 5. The limiting component 6 includes a limiting ring 602 sleeved in the middle of the bolt 5, and a pressing block 601 for pressing the limiting ring 602 is provided on the top of the limiting ring 602.

[0025] Positioning component 7 is located at the connection between the upper shell 2 and the pressing block 601. Positioning component 7 is used to fix the position of pressing block 601.

[0026] A storage hole 603 is provided on one side of the pressing block 601, and the bolt 5 is inserted and connected inside the storage hole 603.

[0027] It should be noted that the motor body 1 is composed of a stator core, coils, rotor, and main shaft. The upper shell 2 and lower shell 3 are respectively located at the top and bottom of the motor body 1. The limiting ring 602 is fixedly sleeved on the bolt 5 near the screw head, and the distance between the limiting ring 602 and the screw head is greater than the height of the pressing block 601, allowing the pressing block 601 to pass between them. When it is necessary to fix the position of the bolt 5, the bolt 5 is turned so that the limiting ring 602 on the bolt 5 fits against the upper shell 2. Then, the pressing block 601 is inserted between the limiting ring 602 and the screw head, and the position of the pressing block 601 is fixed by the positioning component 7. The pressing block 601 prevents the limiting ring 602 from moving away from the upper shell 2, thereby limiting the position of the bolt 5 by restricting its movement, thus preventing the bolt 5 from becoming loose.

[0028] Specifically, the positioning component 7 includes guide grooves 701 symmetrically opened on both sides of the upper shell 2. The guide grooves 701 are used to limit the movement direction of the pressing block 601, and the pressing block 601 is inserted into the interior of the guide grooves 701.

[0029] Specifically, a positioning groove 702 is symmetrically provided at the bottom center of the pressing block 601. A positioning block 703 for fixing the position of the pressing block 601 is inserted and connected inside the positioning groove 702. A moving part 8 for moving the positioning block 703 is provided on one side of the positioning block 703.

[0030] It should be noted that guide grooves 701 are provided on both sides of the upper shell 2, and the width of the guide grooves 701 is appropriate to the width of the pressing block 601. This allows the pressing block 601 to be inserted into the guide groove 701, so that the inner wall of the guide groove 701 restricts the pressing block 601 and prevents it from moving to the sides. Then, the moving part 8 drives the positioning block 703 to move and move the positioning block 703 into the positioning groove 702. The positioning block 703 restricts one side of the pressing block 601 inside the guide groove 701, thereby fixing the position of the pressing block 601.

[0031] Specifically, the movable component 8 includes a drive plate 801 fixedly connected to one end of the positioning block 703. A spring 803 for pulling the drive plate 801 is provided on the side of the drive plate 801 near the positioning block 703. Cavities 802 are symmetrically opened on both sides of the upper shell 2. The drive plate 801 and the spring 803 are both inserted and connected inside the cavity 802. A push column 804 is fixedly connected on the side of the drive plate 801 near the spring 803. The push column 804 is inserted and connected in the middle of the spring 803. Through holes are symmetrically opened on the inner walls of the front and back sides of the cavity 802. The push column 804 is inserted and connected inside the through holes.

[0032] It should be noted that the two ends of the spring 803 are fixedly connected to the inner wall of the cavity 802 and one side of the driving plate 801, respectively. In use, the force of the spring 803 restoring its deformation pulls the driving plate 801 toward one side of the positioning block 703. The bottom end of the driving plate 801 fits against the inner wall of the bottom end of the guide groove 701. When the positioning block 703 on one side is inserted into the positioning groove 702, the blocking force of the positioning block 703 prevents the pressing block 601 with the positioning groove 702 from moving downward. One end of the push column 804 is located outside the cavity 802. In use, the push column 804 pushes the driving plate 801, thereby causing the driving plate 801 to move the positioning block 703 away from the positioning groove 702, thus removing the positioning block 703 from the positioning groove 702 and freeing it from restricting the pressing block 601.

[0033] Specifically, a connecting hole 805 is provided at the bottom of the cavity 802, and the driving plate 801 is inserted into the interior of the connecting hole 805. A guide rod 806 is fixedly connected between the inner walls of the front and back sides of the spring 803, and the guide rod 806 is inserted into the middle of the driving plate 801.

[0034] It should be noted that the connecting hole 805 is used to connect the cavity 802 and the guide groove 701, so that when the top of the driving plate 801 is inside the cavity 802, its bottom end is inside the guide groove 701. When the position of the pressing block 601 is fixed, it is located inside the receiving hole 603, allowing it to slide inside the receiving hole 603. A hole adapted to the guide rod 806 is provided in the middle of the driving plate 801, so that the guide rod 806 can be inserted and connected to the middle of the driving plate 801 through the hole. When the driving plate 801 moves, its direction of movement is restricted by the guide rod 806, preventing it from moving or shaking randomly.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
