[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figures 1 to 6As shown, this utility model can be implemented through the following embodiments: a stacked stator core includes a lamination body 1, a connecting hole 11 is opened on the lamination body 1, a guide rod passes through the connecting hole 11, a limit plate 21 is installed at the end of the connecting rod 2, a heat dissipation hole 12 is opened on the lamination body 1, a connecting groove 3 is opened on the upper end face of the lamination body 1, a connecting groove 4 is opened on the lower end face of the lamination body 1, and a connecting block 5 is installed between the connecting groove 3 and the connecting groove 4.

[0016] The guide rod is used to limit and fix all the stamping bodies 1, ensuring that the stamping bodies 1 are neat and consistent; the limiting plate 21 is used to fix the stamping bodies 1 in conjunction with the guide rod, and at the same time maintains a detachable design with the guide rod, which facilitates the disassembly and replacement of the stamping bodies 1; the heat dissipation hole 12 is used to dissipate heat from the stamping bodies 1; the opening of the connecting groove 1 3 and the connecting groove 2 4 provides a fulcrum for maintenance and disassembly, which facilitates the disassembly and replacement of damaged stamping bodies 1; the connecting block 5 is inserted into the connecting groove 1 3 and the connecting groove 2 4 of the adjacent stamping bodies 1, which facilitates the connection of the stamping bodies 1 in pairs, and improves the efficiency of disassembly and assembly.

[0017] like Figures 1 to 3 As shown, there are two connecting slots 3 and 4, and the angle between the lines connecting connecting slots 3 and 4 is 60°. The two connecting slots 3 and 4 are evenly spaced to ensure even stress distribution on the stamping body 1 during assembly and disassembly, reducing the possibility of damage. The staggered arrangement of connecting slots 3 and 4 at a 60-degree angle prevents them from being located at the same point, which could lead to insufficient local strength in the stamping body 1 and damage during disassembly and installation.

[0018] like Figure 1 and Figure 4 As shown, a positioning groove 31 is provided on the connecting groove 3, and a positioning block 51 is provided on the connecting block 5. The positioning groove 31 is provided to distinguish the connecting groove 3 and the connecting groove 4, thereby improving assembly efficiency; the positioning block 51 is provided so that the connecting block 5 is not symmetrical, which facilitates installation and positioning and improves assembly efficiency.

[0019] like Figure 1 , Figure 2 and Figure 4 As shown, a slot 311 is provided on the positioning groove 31, and a locking block 6 is installed in the positioning block 51. A spring 61 is installed between the locking block 6 and the positioning block 51. The positioning block 51 is fixedly connected to the stamping body 1 through the locking groove 311 and the locking block 6. Pushing the locking block 6 out of the slot 311 facilitates the release of the fixed connection, making disassembly convenient and improving the installation and disassembly efficiency of the stamping body 1. The spring 61 is used to stably lock the locking block 6 into the slot 311, and at the same time provides travel space for the locking block 6 to exit the slot 311.

[0020] like Figure 3 and Figure 4 As shown, a limiting groove is provided on the connecting groove 4, and a sliding plate 52 is provided inside the connecting block 5. The sliding plate 52 and the limiting groove are slidably connected, fixing the connecting block 5 and the connecting groove 4 together, preventing the connecting block 5 from detaching from the stamping body 1, and facilitating disassembly and assembly by the user.

[0021] like Figure 4 and Figure 5 As shown, the slide plate 52 extends with a push rod 53, and the connecting block 5 has a through groove 54. The push rod 53 is provided with a fixing part 531, and the through groove 54 has a fixing groove 541. The fixing part 531 and the fixing groove 541 are connected by a fixing rod 7, which is provided with a thread 71. The push rod 53 is used by the user to slide the slide plate 52, making it easy for the user to control the sliding of the slide plate 52. The fixing part 531 and the fixing groove 541 are paired and connected by the fixing rod 7, so that the slide plate 52 is fixedly connected to the connecting block 5 after being inserted into the limiting groove, preventing the slide plate 52 from falling out of the limiting groove and maintaining the fixed connection between the connecting block 5 and the connecting groove 4. The fixing rod 7 is provided with a thread 71 to prevent the fixing rod 7 from loosening and to ensure a stable connection between the fixing plate and the fixing groove 541.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, a second heat dissipation hole 32 is provided on the connecting groove 3, and a through hole 55 is provided on the connecting block 5. The second heat dissipation hole 32 and the through hole 55 cooperate to allow the hot air inside the stamping body 1 to be discharged through the channel formed by the second heat dissipation hole 32 and the through hole 55, thereby improving the heat dissipation efficiency.

[0023] The working principle of this utility model is as follows: After the stamping body 1 is assembled, when disassembly is required, the limiting plate 21 is removed from the guide rod, the fixing rod 7 is unscrewed, and then the push rod 53 is pushed to drive the sliding plate 52 away from the limiting groove. Then the push block 6 is disengaged from the slot 311. Then the block 6 is pinched to pull the connecting block 5 away from the first connecting slot 3 and the second connecting slot 4. Finally, the stamping body 1 is slid to make the stamping body 1 disengage from the guide rod, thus completing the disassembly.

[0024] When assembly is required, simply reverse the above steps.

[0025] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
