Abstract

The utility model relates to an electromagnetic lock, particularly to an electromagnetic lock used for ferroalloy jars, which comprises a lock bolt 5, a lock end cover 6, a lock core sleeve 7, an electromagnetic coil 8 and a lock bolt insertion sleeve 2, wherein the centre of the lock core sleeve 7 has a step hole. A compression spring 9 is arranged at the bottom of the step hole. One end of the lock bolt 5 is tightly attached to the compression spring 9, and the other end form a taper shape and is exposed outside the lock core sleeve 7. The open end of the lock core sleeve 7 is provided with the lock end cover 6. The lock bolt insertion sleeve 2 is provided with a hole in the position corresponding to the lock bolt 5, and the shape and the size of the hole are matched with the lock bolt 5. The electromagnetic loop 8 which matched with the shape of the lock core sleeve 7 is sheathed outside the other end of the lock core sleeve 7, the electromagnetic loop 8 and the lock core sleeve 7 are movably matched, and the lock core sleeve 7 and the lock bolt insertion sleeve 2 are independent. The utility model has the advantages of simple structure, low using and manufacturing cost, low malfunction ratio, good anti-breakage capability, etc.

Description

A kind of electromagnetic lock

Technical field the utility model relates to a kind of electromagnetic lock, particularly a kind of electromagnetic lock that is used for the ferroalloy jar.

Background technology is present, stolen in transit for preventing case, canned article, all need to install lockset, what install usually is external lockset, external lockset is often prized, and accurate complicated built-in lockset is installed because case, jar body is thick and transport storage environment badly causes going wrong frequently, so the antitheft problem of such case, jar transportation is a difficult problem always, for example the ferroalloy transfer cask used of metallurgy industry just is subjected to the puzzlement of antitheft problem, and valuable ferroalloy is often stolen in transit.

The summary of the invention the purpose of this utility model be to provide a kind of simple in structure, use is cheap for manufacturing cost, fault rate is low, the electromagnetic lock of good destructibility resistance.

For achieving the above object, the technical scheme that the utility model adopted is: a kind of electromagnetic lock, comprise dead bolt 5, lock end cap 6, core cover 7, electromagnetic coil 8, permanent magnet 10, dead bolt sleeve 2, it is characterized in that: there is stepped hole at the center of core cover 7, compression spring 9 places the bottom of stepped hole, one end of dead bolt 5 is close to compression spring 9, the tapered core that is exposed at of the other end overlaps 7 outsides, overlap 7 openends at core lock end cap 6 is arranged, dead bolt sleeve 2 is porose with dead bolt 5 corresponding positions, its shape size matches with dead bolt 5, be with movably electromagnetic coil 8 of individualism that shape with it matches in the outside of the other end of core cover 7,

electromagnetic coil

8 and 7 movable cooperations of core cover, core cover 7 is two independent parts with dead bolt sleeve 2.Permanent magnet 10 is arranged in core cover 7, is surrounded on dead bolt 5, and when electromagnetic coil 8 inserted the outer cover of lock, the magnetic force of permanent magnet 10 was opposite with electromagnetic coil 8 magnetic force when its polarity was opposite, can not open electromagnetic lock, played a protective role.

The utlity model has simple in structure, cheap for manufacturing cost, the advantages such as fault rate is low, good destructibility resistance of use.

The structural representation of description of drawings Fig. 1 electromagnetic lock

The assembling schematic diagram of Fig. 2 electromagnetic lock

The embodiment schematic diagram of Fig. 3 electromagnetic lock

The specific embodiment is described further the utility model below in conjunction with drawings and Examples.

As shown in drawings; a kind of electromagnetic lock; comprise dead bolt 5; lock end cap 6; core cover 7; electromagnetic coil 8; permanent magnet 10; dead bolt sleeve 2; it is characterized in that: there is stepped hole at the center of core cover 7; compression spring 9 places the bottom of stepped hole; one end of dead bolt 5 is close to compression spring 9; the tapered core that is exposed at of the other end overlaps 7 outsides; overlap 7 openends at core lock end cap 6 is arranged; dead bolt sleeve 2 is porose with dead bolt 5 corresponding positions; its shape size matches with dead bolt 5; be with the movably electromagnetic coil 8 that shape with it matches in the outside of the other end of core cover 7,

electromagnetic coil

8 and 7 movable cooperations of core cover, core overlap 7 and dead bolt sleeve 2 are two independent parts; permanent magnet 10 is arranged in core cover 7; be surrounded on dead bolt 5, when electromagnetic coil 8 inserted the outer cover of lock, the magnetic force of permanent magnet 10 was opposite with electromagnetic coil 8 magnetic force when its polarity was opposite; can not open electromagnetic lock, play a protective role.

After embodiment finishes 7 assemblings of core cover, by welding electromagnetic lock 3 is fixedly mounted on the tank body 4, dead bolt sleeve 2 also is fixedly mounted on the cover 1 by welding, both positions are corresponding, for guaranteeing that locking is reliable between dead bolt 5 and the dead bolt sleeve 2, can select the pushing force of the compression spring 9 that uses, general value is proper at 5～20kg, equipped special electromagnetic coil 8, after the energising, electromagnetic coil 8 produces magnetic field, and dead bolt 5 is applied and the reverse electromagnetic force of active force of compressing spring 9, make dead bolt 5 retractions, smooth opening ferroalloy cover 1.

After the outage, because the effect of compression spring 9, dead bolt 5 ejects under the effect of compression spring 9 pushing forces automatically, with 1 locking of ferroalloy cover.

Because electromagnetic coil 8 is movable, after locking, can take off electromagnetic coil 8, arrive again electromagnetic coil 8 covers to be connected and switch on behind the destination and get final product, thereby reach antitheft in transit purpose.
