Be the clearer expression of energy technical characterictic of the present utility model, be described as follows with regard to an embodiment of the present utility model now:

See also Fig. 1, shown in Figure 2, it is respectively stereo appearance figure, the three-dimensional exploded view of the utility model one embodiment, and this embodiment mainly is made up of substrate 10, big ring-like pad 20, little ring-like pad 30, engaging post 40, flexible member 50, electromagnetic component 60, cover body 70, handle rotating shaft 80 etc.

Wherein, substrate 10 is fixedly arranged on the surface of a door-plate (not shown), on this substrate 10 and be provided with a through hole, passes for the set snap fit tabs 13 of core 12 1 ends, and on this core 12 and be arranged with a dead bolt 14, the periphery of this through hole also is provided with three protruding bolts 11.

And big ring-like pad 20 is a magnetic conductive material pad, and its center is provided with a through hole, and this through hole is placed on the snap fit tabs 13 of core 12, and this big ring-like pad 20 is provided with three trepannings 21, and correspondence is inserted in three protruding bolts 11 on the substrate 10.

In addition, little ring-like pad 30 also is a magnetic conductive material pad, and a through hole is established at its center, and this through hole is placed on the snap fit tabs 13 of core 12, the diameter of this little ring-like pad 30 and greater than the through hole of big ring-like pad 20.

One end of engaging post 40 is provided with an engaging shrinkage pool 41, and its correspondence is inserted on the snap fit tabs 13 of core 12, and this engaging post 40 periphery of end in addition is provided with four the first protruding grains 42 of interlock, and the protruding grain of these first interlocks 42 ends with flexible member 50 are sleeved on its central authorities.

And the center of electromagnetic component 60 is provided with a containing hole 61, uses engaging post 40, flexible member 50 therebetween ccontainingly, and this electromagnetic component 60 also is equipped with a power supply (not shown) to produce magnetic force.

See also shown in Figure 3, the sectional schematic diagram of the utility model one embodiment, above-mentioned core 12, big ring-like pad 20, little ring-like pad 30, engaging post 40, elements such as flexible member 50 and electromagnetic component 60 all cover and are overlying in the cover body 70, this cover body 70 is fixed on the substrate 10, on this cover body 70 and be pivoted with leader's rotating shaft 80, the periphery of this handle rotating shaft 80 also is provided with four the second protruding grains 81 of interlock, can corresponding be snapped on the protruding grain 42 of four first interlocks of engaging post 40, and the protruding grain of these second interlocks 81 ends with flexible member 50 are sleeved on its central authorities, this handle rotating shaft 80 also is connected with leader 82, rotates this handle rotating shaft 80 for the operator.

When electromagnetic component 60 not during turn-on power, flexible member 50 will engage post 40 and push against in neutral (seeing also the action schematic diagram of the utility model one embodiment shown in Figure 4), the protruding grain 81 of second interlock of handle rotating shaft this moment 80 separates fully with the protruding grain 42 of first interlock of engaging post 40, therefore swing handle 82 can not be through handle rotating shaft 80, engaging post 40, and makes core 12 rotations; And when electromagnetic component 60 turn-on powers, it will adsorb little ring-like pad 30, big ring-like pad 20, push card zygostyle 40 be located at operating position (see also the utility model one embodiment shown in Figure 5 another the action schematic diagram), protruding grain 81 of four second interlocks of handle rotating shaft this moment 80 and the 42 complete interlocks of the protruding grain of four first interlocks that engage post 40, the rotation of handle 82 can conduct to the snap fit tabs 13 of core 12 through handle rotating shaft 80, engaging post 40, drive core 12 rotations, and then drive dead bolt 12, open the door-plate that electromagnetic lock set firmly.

In the utility model the foregoing description, when the electromagnetic lock door-plate that it is set is sealed, the action of swing handle 82 can not conduct to other members of electromagnetic lock fully, therefore can not cause the wearing and tearing of electromagnetic lock member, so can significantly prolong the useful life of electromagnetic lock.

The above; only be embodiment of the present utility model; only; the interest field that the utility model is advocated; be not limited thereto, press all this skill personages that is familiar with, according to the disclosed technology contents of the utility model; can think easily and various equivalence change, all should belong to protection category of the present utility model.
