Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.

As shown in Figure 1 to 4, shockproof, the Anti-knocking electromagnet apparatus in the present embodiment, including housing, tapered end 1, electric magnet 2.

Housing in the present embodiment includes upper shell 31 and the drain pan 32 of fastening mutually, upper shell 31 and drain pan 32 fastening and is formed with containing cavity, tapered end 1 and electric magnet 2 and is then arranged in this containing cavity.

Wherein tapered end 1 is rotatably connected on the inwall of upper shell 31 by a connection axle, on the inwall of upper shell 31, coupling forms the die cavity 301 rotated for tapered end 1, tapered end 1 part can rotate stretches out outside housing, realizes sealed function thus coordinating with other locking mechanisms outside.

The installation cavity 303 for accommodating electric magnet 2 is also formed in upper shell 31, electric magnet 2 has the movable core 21 stretched out outside installation cavity 303, the periphery of movable core 21 is radially outward convexly equipped with boss 211, movable core 21 is outer is also arranged with spring 22, and the two ends of spring 22 are then against between the outer wall of installation cavity 303 and boss 211 respectively.After tapered end 1 part being screwed out to housing, when electric magnet 2 is not powered on, spring 22 is oppressed movable core 21 and is stretched into die cavity 301 with spacing tapered end 1 so that tapered end 1 keeps sealed state.When electric magnet 2 is energized, then adhesive movable core 21 exits die cavity 301, spacing to tapered end 1 of release, is entirely within die cavity 301 to realize unblock thus tapered end 1 rotates.

Tapered end 1 offers slotted eye 11, can by spacing for tapered end 1 stopping means in situ when being provided with the position-limiting action discharged under movable core 21 is by non-electromagnetic attraction effect tapered end 1 in slotted eye 11.This stopping means can be electric device, machinery etc., the power on signal of motor message and electric magnet as electric device collection activity iron core 21 can be adopted, movable core 21 signal is collected when the power on signal of electric magnet does not occur, a gag lever post is then driven to be against in the spacing hole on housing, such then the position-limiting action to tapered end 1 can be realized, it is to avoid tapered end 1 carries out rotating unlocking in this case.

Stopping means in the present embodiment adopts machinery, and this stopping means includes elastic component 4 and limited block 5.Elastic component 4 suppresses on limited block 5 along the axial spacing direction to movable core 21 of movable core 21.Limited block 5 there is a limit convex key 51 to upper shell 31 inwall is extended, it is matched with convex key 51, the inwall of upper shell 31 axially forms stopper slot 302 along movable core 21, limit convex key 51 vibrations, collide active force under can slip in this stopper slot 302 by compression elastic piece 4, rotate thus limiting tapered end 1.So, when vibrations occurring, colliding, even if when movable core 21 compresses the position-limiting action that spring 22 discharges tapered end 1, limited block 5 also can be effectively ensured the position-limiting action to tapered end 1, avoid the situation by shaking, collide electromagnet apparatus solution lock 1, it is ensured that the sealed safety of this electromagnet apparatus tapered end 1.While movable core 21 resets under the effect of spring 22, limited block 5 also resets under the effect of elastic component 4, and now, movable core 21 has recovered the position-limiting action to tapered end 1.Elastic component 4 in the present embodiment can select the existing elastic components 4 such as spring 22, shell fragment.This limit device structure is simply ingenious, it is possible to what effectively realize tapered end 1 on energy-conservation basis is spacing.

In order to solve the special circumstances of movable core 21 that energising cannot unlock, being additionally provided with in housing can the tripper of manual unlocking tapered end 1.This tripper includes button 61, STATEMENT OF FEDERALLY SPONSORED 62 and torsion spring 63.

Wherein button 61 part stretches out in outside housing, the middle part of STATEMENT OF FEDERALLY SPONSORED 62 connects axle by one and is rotatably connected on the inwall of upper shell 31, torsion spring 63 is fixed on upper shell 31 by a fixing axle, and one end of torsion spring 63 is connected in STATEMENT OF FEDERALLY SPONSORED 62 to realize the reset to STATEMENT OF FEDERALLY SPONSORED 62.The two ends of STATEMENT OF FEDERALLY SPONSORED 62 are against on the boss 211 of button 61 and movable core 21 respectively.When carrying out manual unlocking, manually to pressing keys in housing 61, button 61 promotes one end of STATEMENT OF FEDERALLY SPONSORED 62, so that STATEMENT OF FEDERALLY SPONSORED 62 rotates under button 61 pressing effect, after STATEMENT OF FEDERALLY SPONSORED 62 rotates, the other end of STATEMENT OF FEDERALLY SPONSORED 62 applies pressure on boss 211, it is axially moveable to exit die cavity 301 thus oppressing movable core 21, thus spacing to tapered end 1 of release, tapered end 1 now rotates and is entirely within die cavity 301, completes the manual unlocking of tapered end 1.After tapered end 1 unlocks, discharge button 61, then, under the active force of torsion spring 63, STATEMENT OF FEDERALLY SPONSORED 62 rotates and resets.
