As preferably, in order to make coil can bear the high temperature of injection moulding in the plastic mould the inside, therefore be tied with the resistant to elevated temperatures adhesive plaster of one deck in coil periphery, in order to prevent to expose coil rack distortion above the E shape iron core, upper cover plate is set on coil rack, the centre of the upper cover plate coil shape outer with exposing E sections core adapts, the both ends of upper cover plate are placed on the erection column, and be connected with erection column, prevent plastic coated wire ring framework distortion, prevent that simultaneously the insulating layer that high temperature scorches coil surface from causing coil short.

As preferably, described erection column and E sections core are fixed on by modes such as screw or welding and install on the base plate.

As preferably, plastic cement comes off when preventing injection mo(u)lding, on the outer wall of the two ends of described E sections core and erection column groove is set all, and that the profile of described groove can be is square, rhombus, circle or other shape.

Side on the described erection column and above be provided with installing hole, can in the front or the side Motionless electromagnetic locks on the door or on the doorframe.

Described erection column is provided with wire hole, and the line of wiring board passes wire hole and reaches the outside.

Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, and entire product is put into the plastic mould single injection-molded, preparation method is easy, can improve the production efficiency of electromagnetic lock, reduce production costs, and the strength-enhanced of product.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but not as to qualification of the present utility model.

As shown in Figure 1, described electromagnetic lock comprises E sections core 2, coil 5, wiring board 4, erection column 3, base plate 1 and upper cover plate 6 is installed, described wiring board 4 is fixed in coil 5 bottoms, coil 5 is arranged in the groove of E sections core 2, described erection column 3 is installed on the two ends that base plate 1 is installed respectively by modes such as screw or welding, in the upper surface that base plate 1 is installed, E sections core 2 is positioned in the middle of two erection columns 3 by screw or welded and installed for E sections core 2.The side of described erection column 3 and above be provided with installing hole 9, can in the front or the side Motionless electromagnetic locks on the door or on the doorframe.Described erection column 3 is provided with wire hole 7, and the line of wiring board 4 passes wire hole 7 and reaches the outside.

As preferably, in order to make coil 5 can bear the high temperature of injection moulding in the plastic mould the inside, therefore be tied with the resistant to elevated temperatures adhesive plaster of one deck in coil 5 peripheries, in order to prevent to expose planar coil 5 framework deformation on the E shape iron core, on coil 5 skeletons, upper cover plate 6 is set, the centre of upper cover plate 6 adapts with coil 5 shapes of exposing outside the E sections core 2, the both ends of upper cover plate 6 are placed on the erection column 3, be connected with erection column 3 by screw upper cover plate 6, prevent plastic coated wire ring framework distortion, prevent that simultaneously the insulating layer that high temperature scorches coil surface from causing coil 5 short circuits.

As shown in Figures 2 and 3, as preferably, for the situation that prevents to have the slit between the plastic cement and E sections core 2 after the injection moulding and the plastic cement cracking occurs; Two ends at described E sections core are provided with groove 8; Equally combine more firmly with the erection column of both sides for plastic cement after the injection moulding, erection column 3 both sides on installation base plate 1 both sides are provided with some grooves 8 equally.

The preparation method of the utility model electromagnetic lock is described below:

(1), at first wiring board 4 is fixed in coil 5 bottoms, be installed in then on the conduit of an E shape iron core 2, again E shape iron core 2 and base plate 1 are fixed by the mode of screw or weldering knot, these E shape iron core 2 both sides have the groove 8 of dovetail groove or other form, prevent to exist between the plastic cement and E shape iron core 2 after the injection moulding situation of slit and plastic cement cracking;

(2), the erection column 3 on both sides is fixed on the both sides of installation base plate 1 by the mode of screw or weldering knot, erection column 3 two ends on both sides are provided with some grooves 8 equally, be to combine more firm with the erection column 3 of both sides for plastic cement after the injection moulding, all there is installing hole 9 top the and side of erection column 3 simultaneously, can provide front and side Motionless electromagnetic lock E shape iron core part on door or above the doorframe;

(3), again the line on the wiring board 4 is passed the wire hole 7 of erection column 3 after, loam cake 6 is put in the conduit of E shape iron core 2, two holes that upper cover plate 6 spilt above with screw and the erection column 3 on both sides are fixing, whole winding 5 is covered with by upper cover plate 6 like this, when preventing injection moulding the coil covering scald is caused short circuit, high temperature caused coil 5 framework deformation when simultaneously upper cover plate 6 can prevent injection moulding, caused between the part of product plastic cement after the injection moulding and the E shape iron core 2 to have the slit

(4), measurement circuit part whether normal after, electromagnetic lock E shape iron core is partly finished group power,

(5), group power is put into the injection moulding one-shot forming of plastic mould the inside with whole semiproduct after intact.

Above-mentioned detailed description is specifying at a possible embodiments of the present utility model, this embodiment only is not in order to limit claim of the present utility model, the end breaks away from equivalence enforcement or the change that technical purpose of the present utility model is done, and all should belong to claim of the present utility model.
