Detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1 to Figure 3, one indoor electromagnetic lock of the present invention, including housing 1 and cap 2, cap 2 covers on housing 1, the Electromagnetic lock 12 with scalable dynamic iron core 11 it is provided with in housing 1, in the present invention, the operation principle of Electromagnetic lock 12 is identical with the operation principle of electromagnetic lock in prior art, therefore no longer concrete structure and principle to the Electromagnetic lock 12 in the present invention repeats.
In housing 1, it is additionally provided with locking bolt block 13, locking bolt 14, spring 15, locking bolt shop bolt 3, holddown spring 4 and is connected with Electromagnetic lock 12 and controls the switch 16 of Electromagnetic lock power on/off, locking bolt block 13 is located at the rear side of Electromagnetic lock 12, and the dynamic iron core 11 of Electromagnetic lock 12 is connected on locking bolt block 13, locking bolt 14 is fixedly connected on the left end of locking bolt block 13, and the left end of locking bolt 14 passes the sidewall of housing 1 and stretches out outside housing 1.One end of spring 15 is connected on locking bolt block 13, the other end is connected on the inwall of housing 1, locking bolt shop bolt 3 is connected on locking bolt block 13, and the bottom of locking bolt shop bolt 3 through the underside wall of housing 1 and stretches in outside housing 1, holddown spring 4 one end is connected on locking bolt shop bolt 3, and the other end is connected on cap 2.
Being rotatably connected to switch knob 21 on cap 2, one end of this switch knob 21 is plugged on locking bolt block 13.
Such as Fig. 4 and Fig. 5, being provided with hole 131, location and bar shape trench hole 132 on locking bolt block 13, hole, location 131 connects with bar shape trench hole 132.Being equipped with limit rib 133 on the front and back inwall of bar shape trench hole 132, and be formed with glade plane space between this two limit rib 133, the width of this glade plane space is b, such as Fig. 4.
Such as Fig. 6, the locking bolt shop bolt 3 in the present invention includes first step portion 31, second step portion 32 and the 3rd stage portion 33 that coaxial line direction is arranged.The diameter of the 3rd stage portion 33 in locking bolt shop bolt 3 is less than the width of glade plane space in bar shape trench hole 132 on locking bolt block 13, and the diameter in second step portion 32 is more than the width of above-mentioned glade plane space.Locking bolt shop bolt 3 is connected on the limit rib 133 in bar shape trench hole 132 inwall by second step portion 32.Locking bolt block 13 positions the aperture diameter more than second step portion 32 in hole 131.
Being provided with manhole 100 in the bottom surface of housing 1, this manhole 100 connects with the bar shape trench hole 132 on locking bolt block 13, and locking bolt shop bolt 3 is connected on locking bolt block 13 by bar shape trench hole 132, and is stretched in outside housing 1 by manhole 100.
Electromagnetic lock is when opening, namely locking bolt block 13 drives locking bolt 14 to move right, in locking bolt block 13 motor process, the locking bolt shop bolt 3 limit rib 133 in bar shape trench hole 132 slides, when manhole 100 bottom the hole, location 131 on locking bolt block 13 with housing 1 connects, locking bolt shop bolt 3 is under the effect of holddown spring 4 elastic force, and second step portion 32 landing of locking bolt shop bolt 3 is to the hole, location 131 of locking bolt block 13, and now locking bolt 14 is automatically locked at lock open position.If locking bolt 14 does not arrive above-mentioned lock open position, then locking bolt 14 can automatically return to latched position under the effect of spring 15, thus realizing " automatically reseting " function.
The present invention is for ensureing that spring 15 can stretch smoothly, and the right-hand member at locking bolt block 13 is fixedly connected with guide rod 17, and the right-hand member of this guide rod 17 is through at outside housing 1, and spring 15 is sheathed on this guide rod 17.
The present invention, for be connected between locking bolt shop bolt 3 and cap 2 by holddown spring 4 better, is provided with the first mounting groove (not shown in FIG.) for location and installation holddown spring 4 in the first step portion 31 of locking bolt shop bolt 3.Cap 2 is provided with limiting stand 23, for the second mounting groove 231 of location and installation holddown spring 4 on this limiting stand 23.
Being provided with open keyhole 230 on limiting stand 23, this open keyhole 230 extends on cap 2, for the insertion of key.
Locking bolt block 13 is provided with and stirs groove 137, corresponding, switch knob 21 is provided with and stirs the suitable driving lever of groove 137 22 with this.When opening electromagnetic lock, according to the direction rotating switch handle 21 of unblanking indicated on cap 2 so that locking bolt block 13 drives locking bolt 14 to move right.If namely not contrary with above-mentioned rotation direction of unblanking by the direction rotating switch handle 21(that unblanks indicated on cap 2), the now rotation of limiting stand 23 interferometric switch handle 21.
The dynamic iron core 11 of Electromagnetic lock 12 is connected on locking bolt block 13 by the present invention better, is provided with stopper slot 136 on the sidewall of locking bolt block 13, corresponds ground, is provided with and states the suitable positive stop lug boss of stopper slot 136 11 with this on dynamic iron core 11.
Such as Fig. 7 and Fig. 8, the operating procedure of electromagnetic lock of the present invention is as follows:
(1) normal operation step:
A: pressing lower button, power on, the coil on Electromagnetic lock 12 is subject to electro ultrafiltration so that dynamic iron core 11 departs from the stopper slot 136 on locking bolt block 13.B: to direction rotating switch handle 21 of unblanking, switch knob 21 drives locking bolt block 13 to slide to the right in housing 1, when manhole 100 bottom the hole, location 131 on locking bolt block 13 with housing 1 connects, second step portion 32 landing of locking bolt shop bolt 3 is to the hole, location 131 of locking bolt block 13, now locking bolt 14 is automatically locked at lock open position (such as Fig. 8), then can open cabinet door.If locking bolt 14 does not arrive above-mentioned lock open position, then locking bolt 14 automatically returns to latched position (such as Fig. 7) next time in the effect of spring 15, thus realizing " automatically reseting " function.
C: after cabinet door is opened, locking bolt 14 is locked in above-mentioned lock open position.If closing cabinet door, in closing cabinet door process, clashed into the 3rd stage portion 33 of shop bolt 3 by doorframe 8, the second step portion 32 making shop bolt 3 departs from the hole, location 131 of locking bolt block 13, locking bolt 14 returns to latched position, thus realizing blocking, such as Fig. 9.
(2) manual unlocking step:
Deenergization, fetches solution lock key, inserts in the open keyhole 230 on cap 2, rotates key, dynamic iron core 11 is pushed away locking bolt block 13；Operate by the step b in above-mentioned normal operation step, to meet " manual unlocking " function.
Solving the releasing process of lock key, be that dynamic iron core 11 is pushed away locking bolt block 13, with the effect of unlocking state, and unblank to must flow through rotating switch handle 21 to move locking bolt block 13, reach to unblank purpose, therefore directly can not unblank with key of unblanking.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be regarded as protection scope of the present invention.
