For solving the problems of the technologies described above, the utility model provides a kind of electromagnetic lock, comprise panel body, lockset module and being used to is controlled the switch module that described lockset module opens and closes, described panel body has body, housing fixed support and installation screw rod, described body has front and back, described housing fixed support and installation screw rod are located at the described back side, described lockset module has housing and places the electromagnetic coil and the moving iron core of described enclosure interior, described switch module comprises switch and is used to connect the wiring terminal of the AC power of powering to described electromagnetic coil, described housing is by described housing fixed support, and described body, housing fixed support and installation screw rod are one-body molded.
Further, described switch module also comprises rectification circuit, and described rectification circuit is located between described AC power and the electromagnetic coil, and described switch is located between described rectification circuit and the AC power.
Further, described switch module also comprises the piezo-resistance that can absorb described moving iron core electromotive force, and described piezo-resistance is in parallel with the input of described AC power.
Further, described rectification circuit is a bridge rectifier.
Further, described switch comprises microswitch.
Further, the back side of described body is recessed second mounting groove, described housing described second mounting groove of packing into.
Further, described panel body also has panel, and described front is recessed into first mounting groove, and described panel embeds and is fixed in described first mounting groove.
Further, described body has the screw thread fixing hole at the passed through said front surface and the back side.
A kind of panel body of electromagnetic lock comprises body, housing fixed support and screw rod is installed, and described body, housing fixed support and installation screw rod is one-body molded.
Further, described body, housing fixed support and installation screw rod are metallic object and one die cast.
The beneficial effects of the utility model are: 1) because the monolithic construction that panel body is formed in one makes electromagnetic lock more safe and reliable, improved installation accuracy simultaneously; Owing to reduced the number of individual part, be convenient to more make and assembling, also make product more attractive in appearance.
2) because the electromagnetic lock coil is by direct current supply after passing through the rectification circuit rectification, moving iron core is the just reliable adhesive of energy when adhesive, can not make a noise.
3) because second mounting groove is set, the housing of panel body and lockset module is organically merged, do not see between panel body and the housing that segregation phenomenon is arranged, make product more attractive in appearance.

The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail below by the specific embodiment.
To shown in Figure 7, the present embodiment electromagnetic lock comprises lockset module 2, panel body 1 and is used to control the switch module 3 that lockset module 2 opens and closes as Fig. 2.Lockset module 2 adopts existing structure, lockset module 2 comprises housing 21, places the electromagnetic coil 22 of these housing 21 inside, moving iron core 23, locking bar 24, latching member 25, lock rod spring 26, dial plate 27 and place the lock tube 28 and the handle 29 of these housing 21 outsides, locking bar 24 parts are stretched out this housing 21, and handle 29 is connected with latching member 25.
Switch module can be independent of the setting of lockset module, also can be integrated in the housing 21 of this lockset module.Switch module comprises wiring board and is located at wiring terminal, microswitch K, rectification circuit, current-limiting resistance R and the piezo-resistance RV that connects power supply on this wiring board.Wiring terminal has the first input end and second input that connects power supply.Rectification circuit is used for the alternating current of input is converted to direct current, and the bridge rectifier D1-D4 of this rectification circuit as being made up of four diodes, this bridge rectifier have two first contacts and two second contacts.Two first contacts of rectification circuit connect the first input end and second input respectively, and current-limiting resistance R and indicator lamp LED are serially connected between two second contacts of rectification circuit.The electromagnetic coil 22 of electromagnetic lock is serially connected between two second contacts.Microswitch K is used to control the break-make of electric pathway between power supply and the rectification circuit.
When opening microswitch, the electric pathway conducting, electromagnetic coil 22 gets electric and the moving iron core of adhesive, and moving iron core separates with latching member, and turning handle can be opened electromagnetic lock; When closing microswitch, electric pathway disconnects, electromagnetic coil 22 dead electricity and leave moving iron core, and electromagnetic lock cuts out.
For electromagnetic lock, when interchange was unblanked, because the electromagnetic lock coil is by direct current supply after passing through the rectification circuit rectification, moving iron core is the just reliable adhesive of energy when adhesive, can not make a noise.Owing to increased the piezo-resistance that is used for pressure limiting, can absorb the counter electromotive force that moves iron core, prevent the interference that the counter electromotive force because of switch arcing and moving iron core causes supporting locking type voltage indicator effectively, can not cause the misoperation of voltage indicator contact.Adopt the wiring terminal of standard, can avoid wiring terminal when connecting, to cause sliding tooth, easy-to-connect.
Above content be in conjunction with concrete embodiment to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
