Description

Technical Field

[0001] This utility model relates to the field of motor stator technology, specifically a detachable motor stator. Background Technology

[0002] The stator of a motor is an important component of motors such as generators and starters. The stator consists of three parts: the stator core, the stator windings, and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force in the rotating magnetic field to generate (output) current.

[0003] The existing motor stator is fixed to the inner wall of the motor, and a pair of DC-excited stationary main magnetic poles are installed on it.

[0004] However, existing stationary motor stators cannot be repaired when they are damaged. Repairing them requires breaking the motor casing, which can easily damage the stator, leading to increased maintenance costs and wasted resources.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] The above-mentioned background technology addresses the problem that existing technologies cannot quickly disassemble and fix the motor stator.

[0007] This utility model discloses a detachable motor stator, including a motor housing. Four connecting plates are fixedly connected to the inner wall of the motor housing. Each connecting plate has two slots on its inner wall. A baffle is rotatably connected to the inner wall of each connecting plate. The outer surface of each baffle engages with the corresponding connecting plate. Two locking blocks are fixedly connected to the outer surface of each baffle, and the outer surface of each locking block engages with the corresponding slot. A stator body is slidably connected to the inner wall of the motor housing. The outer surface of the stator body is slidably connected to the four connecting plates. Four connecting blocks are fixedly connected to the outer surface of the stator body, and the outer surface of each connecting block inserts into the corresponding connecting plate.

[0008] Furthermore, the stator body has several stepped grooves inside, and a connecting rod is slidably connected to the inner wall of each stepped groove. A pull block is fixedly connected to the end of each connecting rod away from the corresponding stepped groove.

[0009] Furthermore, each of the connecting rods has a spring sleeved on its outer surface. One end of each spring near the corresponding pull block is fixedly connected to the corresponding connecting rod, and the other end is fixedly connected to the corresponding stepped groove.

[0010] Furthermore, the outer surface of the motor housing is provided with a threaded groove, and a cover is provided on the outer side of the motor housing, with the inner wall of the cover threadedly connected to the threaded groove.

[0011] Furthermore, an extrusion plate is rotatably connected to the inner wall of the cover, and several insert plates are fixedly connected to the side of the extrusion plate near the motor housing.

[0012] Furthermore, the stator body has several sliding grooves on the side near the extrusion plate, and the outer surface of each insert plate is slidably connected to the corresponding sliding groove.

[0013] Furthermore, several screws are inserted into the inner wall of the cover, and several fixing grooves are opened on the outer surface of the motor housing, with the outer surface of each screw threadedly connected to the corresponding fixing groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model includes components such as a motor housing, connecting plates, slots, baffles, locking blocks, stator body, and connecting blocks. By inserting the stator body along the motor housing, the stator body will slide along the four connecting plates. When the stator body is fully inserted, the connecting blocks will be locked in the slots of the corresponding connecting plates. At this time, rotating the baffle and locking it with the corresponding connecting plate will cause the locking blocks to be inserted and fixed with the corresponding slots. Thus, this device can facilitate the quick assembly and disassembly of the motor stator by adjusting the opening and closing of the baffles.

[0016] 2. This utility model, by setting up components such as stepped grooves, springs, connecting rods, pull blocks, shell covers, and extrusion plates, allows the extrusion plates to press the pull blocks, causing the corresponding connecting rods to slide along the corresponding stepped grooves. At this time, the springs are compressed. Then, when the shell covers are removed, the springs will push the corresponding connecting rods to move in the opposite direction along the corresponding stepped grooves under the action of their rebound force. This achieves the effect that the stator body can be quickly disassembled from the motor housing by pulling the pull blocks. Attached Figure Description

[0024] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in the illustrations in a simple schematic manner.

[0025] Please see Figure 4 , Figure 5 This utility model discloses a detachable motor stator, including a motor housing 1. Four connecting plates 15 are fixedly connected to the inner wall of the motor housing 1. The four connecting plates 15 are evenly distributed on the inner wall of the motor housing 1. Each connecting plate 15 has two slots 18 on its inner wall. A baffle 16 is rotatably connected to the inner wall of each connecting plate 15, allowing the baffle 16 to rotate within its corresponding connecting plate 15. Two elastic plates are fixedly connected to the outer surface of each baffle 16, and the outer surface of each baffle 16 engages with its corresponding connecting plate 15. When the baffle 16 is rotated, it rotates around the central axis at its connection point with the corresponding connecting plate 15, causing the two elastic plates to engage inside the corresponding connecting plate 15. Two locking blocks 17 are fixedly connected to the outer surface of each baffle 16, positioned on the corresponding elastic plates. During the engagement of the connecting plate 15, two fingers are used to squeeze the corresponding elastic plate, pressing the connecting plate 15 to engage the locking blocks 17 with the corresponding slots 18, thus quickly fixing the baffle 16.

[0026] In a preferred embodiment, the outer surface of each locking block 17 engages with the corresponding slot 18. The inner wall of the motor housing 1 is slidably connected to the stator body 7. A limiting groove is formed on the outer surface of the stator body 7. Before fixing the baffle 16, the stator body 7 is first inserted along the motor housing 1. During this process, the limiting groove engages with the corresponding connecting plate 15. The limiting groove can limit the stator body 7. The outer surface of the stator body 7 is slidably connected to the four connecting plates 15. Four connecting blocks 14 are fixedly connected to the outer surface of the stator body 7. The outer surface of each connecting block 14 is inserted into the corresponding connecting plate 15. Specifically, after the stator body 7 is installed, the connecting block 14 will engage in the corresponding connecting plate 15. Then the baffle 16 is installed. At this time, the fixing of the baffle 16 will fix the connecting block 14, thereby quickly fixing the stator body 7.

[0027] like Figure 2 , Figure 3 As shown, the stator body 7 has several stepped grooves 10 inside. Each stepped groove 10 has a connecting rod 11 slidably connected to its inner wall. Each connecting rod 11 can slide along the corresponding stepped groove 10. Each connecting rod 11 has a limit ring fixedly connected to its outer surface. The limit ring can slide along the corresponding stepped groove 10. Each connecting rod 11 has a pull block 13 fixedly connected to its end away from the corresponding stepped groove 10. By pulling the pull block 13, the pull block 13 can drive the stator body 7 to slide out of the motor housing 1.

[0028] In this embodiment, a spring 12 is sleeved on the outer surface of each connecting rod 11. One end of each spring 12 near the corresponding pull block 13 is fixedly connected to the corresponding connecting rod 11, and the other end is fixedly connected to the corresponding stepped groove 10. Specifically, by squeezing the pull block 13, the pull block 13 will drive the corresponding connecting rod 11 into the corresponding stepped groove 10, and the pull block 13 will engage with the stator body 7. At this time, the spring 12 will be compressed. Then, when no external force is applied to the pull block 13, the spring 12 will push the corresponding connecting rod 11 under its rebound force and push the corresponding pull block 13 to pop out, making it easy to pull.

[0029] In this embodiment, the outer surface of the motor housing 1 is provided with a threaded groove 5, and the outer side of the motor housing 1 is provided with a cover 2. The inner wall of the cover 2 is threadedly connected to the threaded groove 5. Specifically, by rotating the cover 2, the cover 2 can be connected to the motor housing 1 along the threaded groove 5.

[0030] In this embodiment, an extrusion plate 3 is rotatably connected to the inner wall of the cover 2. The extrusion plate 3 can rotate on the cover 2. Several insert plates 6 are fixedly connected to the side of the extrusion plate 3 near the motor housing 1. Specifically, the insert plates 6 are placed vertically on the extrusion plate 3, and the length of the insert plates 6 is longer than that of the cover 2.

[0031] In this embodiment, the stator body 7 has several sliding grooves 8 on the side near the extrusion plate 3. The outer surface of each insert plate 6 is slidably connected to the corresponding sliding groove 8. Specifically, before installing the cover 2, the insert plate 6 should be inserted into the corresponding sliding groove 8. Then, when installing the cover 2, the extrusion plate 3 will rotate relative to the cover 2 through the connection between the insert plate 6 and the corresponding sliding groove 8.

[0032] like Figure 1 , Figure 2 As shown, several screws 4 are inserted into the inner wall of the cover 2, and several slots are opened on the outer surface of the cover 2. The screws 4 can be inserted into the corresponding slots. Several fixing slots 9 are opened on the outer surface of the motor housing 1. After the cover 2 is installed, the slots will be on the same central axis as the corresponding fixing slots 9. The outer surface of each screw 4 is threaded to the corresponding fixing slot 9. Specifically, by inserting the screw 4 into the corresponding slot and then rotating the screw 4 to connect it with the corresponding fixing slot 9, the cover 2 can be fixed more stably and firmly.
