AI Technical Summary
The connection method between the moving iron core and the lock core of the existing electromagnetic lock has two major problems: the hole shaft interference riveting and threaded connection. The former can easily lead to the separation of the iron core and the lock core, while the latter is high in cost and may lead to the unsmooth movement of the iron core.
One end of the moving iron core is equipped with an assembly groove, and one end of the lock core is equipped with a tapered assembly head, which is riveted into the assembly groove through the assembly head, and the shrinking opening of the assembly groove matches the shape of the assembly head, achieving a simpler and more economical connection method. .
The stable connection between the moving iron core and the lock core is achieved, and it can withstand axial tension of 300N without loosening, reducing assembly cost and complexity.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electromagnetic locks, in particular to an assembly structure of an electromagnetic lock moving iron core and a lock core. Background Art
[0002] Due to the working principle of the electromagnetic lock, the moving iron core and the lock core are designed as parts of two different materials. The two parts are basically connected together by straight hole and shaft (or knurled) interference riveting or threaded connection.
[0003] 1. Interference riveting of straight hole and shaft: The clearance between the hole and shaft is very high. If the interference is small, it is easy to cause the iron core and the lock core to separate when used under force for a long time, and the product function will fail. If the interference is too large, the lock core may bend or the suction cone of the iron core may deform during riveting.
[0004] 2. Threaded connection: The connection is reliable and thread locking glue needs to be added during assembly to prevent the thread from loosening during long-term use. However, the cost is high and the glue can easily contaminate the surface of the moving iron core or stick to impurities, causing the iron core to move unsmoothly. Summary of the invention
[0005] According to an embodiment of the utility model, an assembly structure of an electromagnetic lock moving iron core and a lock core is provided, comprising:
[0006] A moving iron core, one end of which is provided with a mounting groove;
[0007] A lock core, one end of which is provided with an assembly head;
[0008] The assembly head is riveted into the assembly groove, and the assembly groove is shrunk toward the assembly head, so that the assembly head is clamped in the assembly groove.
[0009] Furthermore, the shape of the assembly groove after shrinkage matches the shape of the assembly head.
[0010] Further, the assembly head is tapered.
[0011] Furthermore, the material of the moving iron core is DT4C.
[0012] Furthermore, the material of the lock core is SUS304.
[0013] According to an assembly structure of an electromagnetic lock moving iron core and a lock core in an embodiment of the utility model, the overall structure is simple, the cost is low, and the assembly is more convenient. After the moving iron core and the lock core are assembled, they can withstand an axial tensile force of 300N without loosening.
[0014] It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the technology as claimed. BRIEF DESCRIPTION OF THE DRAWINGS
