The teeth on the upper toothed disc and the teeth on the lower toothed disc are in a T shape. Protrusions for preventing the rotation of the iron core and limiting the positions of the lower toothed disc are arranged in the mounting shell. An unlocking arm is further included, and the unlocking arm is arranged on the upper toothed disc and stretches out of the surface of the mounting shell. Compared with the prior art, the mutual meshing of the toothed discs is used in the electromagnetic lock for locking a lockset, unlocking is conducted through the attraction of the magnet, and the electromagnetic lock is simple in structure, easy to achieve, few in part and convenient to maintain.
Description
Technical field
The utility model 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.
Utility model content
Utility model object: the purpose of this utility model is to provide a kind of simple structure, is easy to safeguard, and the electromagnetic lock of long service life.
Technical scheme: the utility model adopts following technical scheme to realize: a kind of electromagnetic lock, comprise mounting shell, in mounting shell, arrange and contain space, contain space 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 to the utility model, utilizes the absorption of magnet to unblank, simple in structure, be easy to realize, and part is few, and it is convenient to safeguard.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
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 utility model is described in further detail:
The utility model 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.
Bottom at 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 mesh, an other side at 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 utility model 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, the unlocking arm that fluted disc stretches out mounting shell is stirred 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.
