Abstract
The invention relates to an electromagnetic lock. The electromagnetic lock comprises a mounting shell, wherein a holding space is formed in the mounting shell; an electromagnet, an iron core, an upper fluted disc, a lower fluted disc and a shifting fork are arranged in sequence in the holding space; the electromagnet is arranged on the upper portion of the mounting shell, and the iron core is coaxially and fixedly connected with the upper fluted disc; the lower fluted disc is coaxially and fixedly connected with the shifting fork; a gap exists between the electromagnet and the iron core; opposite sides of the upper fluted disc and the lower fluted disc are provided with teeth which can be meshed together respectively; a connecting shaft between the lower fluted disc and the shifting fork is provided with a torsion spring for returning the shifting fork to an unlocking position. The teeth on the upper fluted disc and the lower fluted disc are T-shaped teeth. Bumps for preventing the iron core from rotating and limiting the position of the lower fluted disc are formed in the mounting shell. The electromagnetic lock further comprises an unlocking arm which is arranged on the upper fluted disc and extends out of the surface of the mounting shell. Compared with the prior art, the electromagnetic lock has the advantages of realization of locking of a lockset by means of mutual meshing of the fluted discs and unlocking by means of adsorption of a magnet, simple structure, easiness in implementation, less parts and convenience in maintenance.
Description
Technical field
The present invention relates to a kind of lockset of track communicating door, specifically, is the electromagnetic lock using on a kind of track traffic driver door.
Background technology
The general use of door lock that on rail traffic vehicles, driver uses goed deep into locking or use lock fork rotation locking in stopper, and traditional fork lock adopts gear locking, its complex structure, not easy care; And traditional lockset gear is easily stuck, to routine use, makes troubles.
Summary of the invention
Goal of the invention: the object of the present invention is to provide a kind of simple structure, be easy to safeguard, and the electromagnetic lock of long service life.
Technical scheme: the present invention adopts following technical scheme to realize: a kind of electromagnetic lock, comprise mounting shell, in mounting shell, arrange and contain space, contain sky set gradually electromagnet, iron core, on fluted disc, lower tooth disk, shift fork, top, iron core that electromagnet is arranged on mounting shell are coaxially fixedly connected with upper fluted disc, lower tooth disk is coaxially fixedly connected with shift fork, between electromagnet and iron core, there is space, in a upper fluted disc side relative with lower tooth disk, arranging respectively can intermeshing tooth, when shift fork turns to locked position, upper fluted disc and lower tooth disk are intermeshing.
The torsion spring that makes shift fork return back to unlocked position is set on the connecting axle of lower tooth disk and shift fork.
Tooth on upper fluted disc and lower tooth disk is T shape tooth.
In mounting shell, arrange and stop iron core to rotate and limit the projection of lower tooth disk position.
Also comprise unlocking arm, described unlocking arm is arranged on fluted disc and stretches out mounting shell surface.
Beneficial effect: compared with prior art, it utilizes the intermeshing of fluted disc to carry out locking to lockset, utilizes the absorption of magnet to unblank, simple in structure in the present invention, be easy to realize, and part is few, and it is convenient to safeguard.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein 1-mounting shell, 2-electromagnet, 3-iron core, the upper fluted disc of 4-, 5-lower tooth disk, 6-torsion spring, 7-shift fork, 8-unlocking arm.
The specific embodiment
Below in conjunction with Figure of description, the present invention is described in further detail:
The present invention relates to a kind of electromagnetic lock, specifically, is the fork lock of using on a kind of rail vehicle driver door.It comprises the mounting shell 1 of a metal, one electromagnet 2 is set in the containing space in mounting shell 1, electromagnet is arranged on the top of containing space, near the place of electromagnet downside, be provided with iron core 2, when electromagnet 1 when electric, electromagnet 1 picks up iron core 2, after power down, iron core 2 falls after rise to original position, 2 projections are set on mounting shell 1, groove corresponding to position size is with it set on iron core 2, iron core just cannot rotate in mounting shell like this.
At the downside of iron core 2, be fixedly installed fluted disc 3, specifically, iron core 2 is integrally welded with upper fluted disc 3, and because iron core 2 cannot rotate, upper fluted disc 3 also moves up and down and not rotatable only in mounting shell 1, and some T shape teeth are set on upper fluted disc.
In the bottom of upper fluted disc 3, lower tooth disk 4 is set, some T shape teeth are also set on lower tooth disk, specifically, described T shape tooth is separately positioned on the face that fluted disc 3 and lower tooth disk 4 be in contact with one another, and two groups of T shape teeth can interlacedly engage, in an other side of lower tooth disk, be fixedly installed a connecting axle, connecting axle is fixedly connected with shift fork 7, and lock fork 7 is arranged on the outside of mounting shell 1, between lock fork 7 and mounting shell 1, bearing is set, spacing due to lock fork 7, lower tooth disk 4 rotates only and can not move up and down in mounting shell.
A torsion spring 6 is set on connecting axle, and when there is no External Force Acting, torsion spring drives lock fork 7 to return back to unlocked position.
A unlocking arm is set on upper fluted disc 3, and unlocking arm stretches out mounting shell, on mounting shell correspondence position, groove is set.
Below by an object lesson, the present invention is described:
In the release stage of door leaf, the T shape tooth on upper fluted disc and lower tooth disk props up mutually, and lower tooth disk is free to rotate; When door leaf lock pin moves with door, lock pin promotes shift fork and rotates, and shift fork drives lower tooth disk to rotate, and turns to the lower tooth disk position of engagement, and upper fluted disc is because Action of Gravity Field moves down, and upper lower tooth disk engagement, stops shift fork revolution, reaches locking object; Electromagnet energising during release, pull-core, iron core drives upper fluted disc to move up, upper lower tooth disk disengaged position, under torsion spring effect, lower tooth disk and shift fork rotate, and door leaf lock pin leaves locked position, realizes release.During manual unlocking, fluted disc is stirred and stretches out the unlocking arm of mounting shell in outside.Fluted disc is moved up, upper lower tooth disk disengaged position, under torsion spring effect, lower tooth disk and shift fork rotate, and door leaf lock pin leaves locked position, realizes release.
