The specific embodiment

Below in conjunction with accompanying drawing the utility model is made and to be further described.

With reference to figure 1 and Fig. 2, electromagnetism lock core of the present utility model comprises plug positioning seat 1, handle plug 2, electromagnet assembly 3, front shroud 4, handle panel 5, handle 6 and key core 7.Plug positioning seat 1 is fixed on the front shroud 4, is provided with a through hole on plug positioning seat 1; Handle plug 2 is arranged in this through hole, and is limited the rotation angle range of this handle plug 2 by a position-limit mechanism.In conjunction with shown in Figure 4, this position-limit mechanism comprises and is arranged on the deep-slotted chip breaker 11 on the plug positioning seat 1 and is arranged on a alignment pin 21 on the handle plug 2 that alignment pin 21 is embedded in this deep-slotted chip breaker 11.Front shroud 4 and the handle panel 5 common cavitys 51 that limit, handle panel 5 are provided with a through hole 52 that is communicated in this cavity 51.Handle 6 comprises body 61 and is connected in the handle portion 62 of this body 61 that body 61 is arranged in the through hole 52 of handle panel 5 rotationally, is arranged with jump ring 8, spacer 9 and torsion spring 10 on the perisporium of body 61 according to this.Body 61 is provided with a centre bore 63, and key core 7 is arranged in the centre bore 63 of body 61.

Electromagnet assembly 3 comprises electromagnetic coil 33 and electromagnetism plug 34.This electromagnetic coil 33 has a shell body 331 and a centre bore 332.One end of shell body 331 passes front shroud 4, and connects with handle plug 2 by a plurality of screws, and the other end extend in the centre bore 63 of handle body portion.One end of electromagnetism plug 34 stretches in the centre bore 332 of electromagnetic coil, and the other end and key core 7 are oppositely arranged.The other end of electromagnetism plug 34 also is provided with a fastener 36, and this fastener 36 can be followed handle and be rotated together.The other end of shell body 331 offers first fastener slots 333 that is used for ccontaining fastener 36.

In one embodiment, fastener 36 is for vertically passing a stainless steel bar of the other end of electromagnetism plug 34, the end face of the other end of the shell body 331 of electromagnetic coil offers a pair of first fastener slots 333, and the two ends of fastener 36 are embedded in respectively in this a pair of first fastener slots 333.The hole wall of the centre bore 63 of the body 61 of handle offers second fastener slots 66 of a pair of ccontaining fastener 36, and the two ends of fastener 36 are embedded in respectively in this a pair of second fastener slots 66.Be arranged with a back-moving spring 35 on the electromagnetism plug 34, the inwall of the shell body 331 of electromagnetic coil is provided with an annular lip 335, and an end of back-moving spring 35 supports and is located on this annular lip 335.
