Embodiment:
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, a kind of indoor electromagnetic lock of the present invention, including housing 1 and cap 2, cap 2 are covered in housing 1 On, be provided with the Electromagnetic lock 12 with scalable dynamic iron core 11 in the housing 1, in the present invention operation principle of Electromagnetic lock 12 with The operation principle of electromagnetic lock is identical in the prior art, therefore no longer to the concrete structure and principle of the Electromagnetic lock 12 in the present invention Repeated.
Be additionally provided with housing 1 locking bolt block 13, locking bolt 14, spring 15, locking bolt shop bolt 3, holddown spring 4 and with Electromagnetic lock 12 is connected and controls the switch 16 of Electromagnetic lock power on/off, and 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, and locking bolt 14 is fixedly connected on the left end of locking bolt block 13, and locks The left end of bolt 14 passes through the side wall of housing 1 and stretched out outside housing 1.One end of spring 15 is connected on locking bolt block 13, the other end It 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 passes through The underside wall of housing 1 is simultaneously stretched in outside housing 1, and the one end of holddown spring 4 is connected on locking bolt shop bolt 3, and the other end is connected to shell On lid 2.
Switch knob 21 is rotatably connected on cap 2, one end of the switch knob 21 is plugged on locking bolt block 13.
Such as Fig. 4 and Fig. 5, positioning hole 131 and bar shape trench hole 132, positioning hole 131 and bar-shaped trough are provided with locking bolt block 13 Hole 132 connects.Limit rib 133 is being equipped with before and after bar shape trench hole 132 on inwall, and is being formed between two limit rib 133 There is glade plane space, the width of the glade plane space is b, such as Fig. 4.
Such as Fig. 6, the locking bolt shop bolt 3 in the present invention includes 31, second, the first step portion that coaxial line direction is set The stage portion 33 of rank portion 32 and the 3rd.The diameter of the 3rd stage portion 33 in locking bolt shop bolt 3 is less than on locking bolt block 13 articles The width of glade plane space in shape slotted eye 132, the diameter in second step portion 32 are more than the width of above-mentioned glade plane space.Locking bolt alignment pin Nail 3 is connected on the limit rib 133 in the inwall of bar shape trench hole 132 by second step portion 32.The upper Positioning holes 131 of locking bolt block 13 Aperture be more than second step portion 32 diameter.
Manhole 100, the manhole 100 and the bar shape trench hole 132 on locking bolt block 13 are provided with the bottom surface of housing 1 Connect, locking bolt shop bolt 3 is connected on locking bolt block 13 by bar shape trench hole 132, and stretches in shell by manhole 100 Outside body 1.
For electromagnetic lock when opening, i.e., locking bolt block 13 drives locking bolt 14 to move right, in the motion process of locking bolt block 13, Locking bolt shop bolt 3 slides on the limit rib 133 in bar shape trench hole 132, when the positioning hole 131 and housing on locking bolt block 13 When the manhole 100 of 1 bottom connects, locking bolt shop bolt 3 is in the presence of the elastic force of holddown spring 4, locking bolt shop bolt 3 Second step portion 32 slide to the positioning hole 131 of locking bolt block 13, now locking bolt 14 be automatically locked at lock open position.If When locking bolt 14 is without above-mentioned lock open position is reached, then locking bolt 14 can automatically return to latched position in the presence of spring 15, from And realize " automatically reseting " function.
The present invention can smoothly be stretched for guarantee spring 15, and guide rod 17 is fixedly connected with the right-hand member of locking bolt block 13, The right-hand member of the guide rod 17 is through at outside housing 1, and spring 15 is sheathed on the guide rod 17.
Holddown spring 4 is preferably is connected between locking bolt shop bolt 3 and cap 2 by the present invention, in locking bolt alignment pin The first step portion 31 of nail 3 is provided with the first mounting groove for location and installation holddown spring 4(It is not drawn into figure).In cap 2 Limiting stand 23 is provided with, the second mounting groove 231 of location and installation holddown spring 4 is used on the limiting stand 23.
Open keyhole 230 is provided with limiting stand 23, the open keyhole 230 is extended on cap 2, the insertion for key.
It is provided with locking bolt block 13 and stirs groove 137, it is corresponding, it is provided with switch knob 21 and stirs groove with this 137 driving levers 22 being adapted.When opening electromagnetic lock, according to the unlocking direction rotating switch handle 21 indicated on cap 2 so that Locking bolt block 13 drives locking bolt 14 to move right.If not by the unlocking direction rotating switch handle 21 indicated on cap 2(I.e. with Above-mentioned unlocking rotation direction is opposite), the now rotation of the interferometric switch handle 21 of limiting stand 23.
The dynamic iron core 11 of Electromagnetic lock 12 is preferably is connected on locking bolt block 13 by the present invention, in locking bolt block 13 Side wall is provided with stopper slot 136, correspond ground, in dynamic iron core 11 be provided with this state stopper slot 136 be adapted it is spacing Boss 11.
As Fig. 7 and Fig. 8, the operating procedure of electromagnetic lock of the present invention are as follows:
(1)Normal operation step:
a:Press lower button, power on, the coil on Electromagnetic lock 12 is by electro ultrafiltration so that dynamic iron core 11 departs from locking bolt gear Stopper slot 136 on block 13.
b:To unlocking direction rotating switch handle 21, switch knob 21 drives locking bolt block 13 to be slided to the right in housing 1, works as lock When positioning hole 131 and the manhole 100 of the bottom of housing 1 on bolt block 13 connect, the second step of locking bolt shop bolt 3 Portion 32 is slid to the positioning hole 131 of locking bolt block 13, and now locking bolt 14 is automatically locked at lock open position(Such as Fig. 8), then can beat Open cabinet door.If locking bolt 14 is without above-mentioned lock open position is reached, then locking bolt 14 returns in the presence of spring 15 and automatically returns to lock Positioning is put(Such as Fig. 7), so as to realize " automatically reseting " function.
c:After cabinet door is opened, locking bolt 14 is locked in above-mentioned lock open position.If closing cabinet door, during cabinet door is closed, lead to Cross the 3rd stage portion 33 that doorframe 8 hits shop bolt 3 so that the second step portion 32 of shop bolt 3 departs from locking bolt block 13 Positioning hole 131, locking bolt 14 returns to latched position, so as to realize blocking, such as Fig. 9.
(2)Manual unlocking step:
Deenergization, solution lock key is fetched, inserted in the open keyhole 230 on cap 2, rotated key, dynamic iron core 11 is pushed away From locking bolt block 13;Operated by the step b in above-mentioned normal operation step, to meet " manual unlocking " function.
The releasing process of lock key is solved, is that dynamic iron core 11 is pushed away into locking bolt block 13, with the effect of unlocking state, and Unlocking must move locking bolt block 13 by rotating switch handle 21, reach unlocking purpose, therefore unlocking key can not be used straight Connect unlocking.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, some improvement can also be made under the premise without departing from the principles of the invention, and these improvement also should be regarded as the present invention's Protection domain.
