Abstract
The utility model discloses an electromagnetic door lock which can be operated and unlocked remotely. The utility model is composed of a casing, a lock head, a lock pin, a knob and a safety button, wherein the knob and the safety button are arranged on the casing. The lock pin is connected with a movable magnet of an electromagnet; a coil of the electromagnet is serially connected with a power switch, and the power switch is installed on the place which is far away from the door lock, such as a bedroom or a duty room. Not only a door can be opened by a key and the knob, but also the power switch can be used for causing the electromagnet to generate magnetic force to unlock the lock door. The power switch can be a pull switch, a sub-ultrasonic switch or a far infrared remote control switch. The electromagnetic door lock can be installed on household courtyard doors, company doors or entrance doors of the whole building.
Description
The utility model relates to electric power or magnetic force to be handled or the door lock of control, particularly a kind of can remotely-controlled electromagnetic door lock.
Existing door lock for example is installed in the various built-in locks of house door limit portion.It is made up of shell, tapered end, locking bolt and the knob and the stop button that are installed on the housing.Tapered end opens the door or closes the door for inserting key.Locking bolt is by the dead bolt of expansion link and front end thereof, and the spring and the end plate that are enclosed within on the expansion link are formed.Knob and expansion link afterbody are connected as a single entity, and turn knob and can make expansion link and dead bolt move left and right.Stop button is installed in the housing outside corresponding to latch bolt position, when dead bolt stretched into doorframe (knocker), the room owner can push away stop button on vertically and make its front end insert the right vertical slot of dead bolt, and can not unblank to open the door with key this moment, other people can not inlet chamber in, stop button has security function.If people need inside and outside the frequent access door, available knob pulling expansion link is got back in the lock housing dead bolt, and stop button pushed away on vertically makes its front end insert dead bolt left side vertical slot, this moment, dead bolt was positioned in the lock housing, people's sliding door that can arbitrarily push is is freely come in and gone out, and stop button has the function of convenience.
But existing door lock still can not be by people's far distance controlled, and people have only near it and just can open the door or close the door.Like this, it can not satisfy people's special requirement, for the house gate that this door lock is housed, the building entrance gate of the entrance gate of enterprises and institutions of organ, centralized management, when people need pass in and out, the relevant personnel must go to a side opening door from place far away or close the door, if the relevant personnel are the elderly, disabled person or security personnel, he (she) will feel that the switch door operation is a trouble.If this operation in the winter time or chill night or snowy and rainy day carry out, he (she) will feel not only to bother but also arduous.
The purpose of this utility model provides and a kind ofly can contact the electromagnetic door lock that unlatching again can remote operation be opened.
For achieving the above object, electromagnetic door lock of the present utility model mainly is made up of knob on shell, tapered end, locking bolt and the housing and stop button.Described locking bolt is connected with the moving iron phase of an electromagnet, and this magnet spool is connected with a power switch, and this power switch is installed in the place of high door lock far away.People can insert tapered end or twisting housing outer knob with key and make the locking bolt indentation or stretch out and realize opening the door or locking a door.People also can make the closed or disconnection of power switch in the place away from door lock, thereby make electromagnet produce magnetic force or magnetic force disappearance, make the locking bolt indentation or stretch out to reach the purpose of opening the door or locking a door.
In above-mentioned electromagnetic door lock, an end of described locking bolt is formed to the thin type flat board, and the moving iron of this flat board and electromagnet is riveted together.
In above-mentioned door lock, described magnet spool is connected with a pullswitch.
In above-mentioned door lock, described magnet spool shakes the control switch with a far infrared and connects.
In above-mentioned door lock, described magnet spool is connected with a ultrasonic control switch that shakes in Asia.
After adopting said structure, because this door lock is provided with the power switch of electromagnet and high door lock far away, people needn't go to the door lock next door and go to open the door, can in bedroom, parlor, janitor's room, handle the power switch that is installed in the room and finish opening door operation, this door lock brings great convenience to the elderly and the disabled, alleviated operator on duty's labour intensity, in the winter time, night, snowy and rainy day the people that opens the door will avoid the hardship of cold.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a specific embodiment of the utility model electromagnetic door lock.
Electromagnetic door lock shown in Figure 1 is made up of shell 1, locking bolt 2, electromagnet 3 and power switch K.Locking bolt 2 is made up of dead bolt 4, expansion link 5, spring 6 and end plate 7.Locking bolt 2 is in the lock state in Fig. 1, and promptly dead bolt 4 is positioned at the cavity of knocker 8.Electromagnet 3 is made up of quiet iron 9, moving iron 10 and coil 11.Knob and stop button on tapered end, the housing do not draw among Fig. 1.
As shown in Figure 1, the right-hand member of cylindrical expansion link 5 is processed to thin type flat board 12, and rivet 13 is riveted together flat board 12 and moving iron 10.
As shown in Figure 1, an end of coil 11 is electrically connected with the C of power switch K end, and the A end of K switch and the B end of coil 11 are electrically connected with the live wire and the zero line of 220 volts of alternating currents respectively.
Power switch K is installed in the place away from electromagnetic door lock, as household bedroom or parlor, and entrance guard's janitor's room of enterprises and institutions of organ, entrance guard's janitor's room in the entire building room of centralized management.
The use of this electromagnetic door lock can be inserted tapered end or rotate with the shell outer knob and opened the door with key.When utilizing power switch to open the door, should make the K switch closure, coil 11 energisings produce magnetic field, drive expansion link 5 and dead bolt 4 are got excited to the right thereby the moving iron 10 of quiet iron 9 attractions is got excited to the right, shell 1 stops end plate 7 compression springs 6, dead bolt 4 withdraws from the cavity of knocker 8, and this moment, locking bolt 2 was in opening, can realize opening the door.When power switch disconnects, coil 11 outages, magnetic force disappears, and the elastic force promotion dead bolt of spring 6 drives the moving iron 10 of expansion link 5 pullings and resets, locking bolt recovery this moment lock-out state, door can be lockable.Dispose different power switch K, this electromagnetic door lock has different class, the low-cost pullswitch of selecting for use.Middle-grade Zhengzhou City, selected for use Henan Province orchid flies the inferior ultrasonic control switch that shakes that power electronics research institute produces.The far infrared that high-grade selected for use Henan Prov. Inst. produces is shaken the control switch.
Use this electromagnetic door lock, can be on circuit electric bell in parallel and indicator lamp opened with door so that known whether messenger, with good conditionsi can be on circuit talkback unit in parallel and language device so that tightening security property and decorum.
