Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with specific embodiment, the present invention will be further described.Should be understood that following examples are only for the present invention is described but not for limiting the scope of the invention.
Referring to Fig. 1, a kind of electromagnet mechanism formula door lock of centrifuge provided by the invention, comprise body 1 and door closure 2, described body 1 top is provided with left/right hook 3, 4, door closure bottom is provided with left/right links up with suitable left/right dead bolt 5, 6, by left/right is linked up with to 3, 4 are inserted into left/right dead bolt 5, in 6, realize closing of body 1 and door closure 2, in order to solve the technical problem described in background technology, technical scheme of the present invention is, provide a kind of and can automatically left/right be linked up with to 3, 4 are inserted into left/right dead bolt 5, automatic locking mechanism 7 in 6, described automatic locking mechanism 7 comprises and is connected to left/right hook 3, the lock body fixed head 71 of 4 bottoms, described left/right hook 3, 4 are all hinged on lock body fixed head 71, described lock body fixed head 71 1 sides also parallel being provided with are connected to described left/right hook 3, between 4, can drive left/right hook 3, 4 insert simultaneously or leave left/right dead bolt 5, 6 Z-type elastic pusher 72, in the present embodiment, described elastic pusher 72 adds shock mount 73 by push pedal plate body and is formed, by pressing, be arranged on push pedal plate body one end and stretch out the Level Promoting that dark cover 74 outside body 1 is realized elastic pusher 72, utilizing spring 73 to realize resets.
In order to guarantee the stable state of elastic pusher 72 when pushing and reset, technical scheme of the present invention is, the other end at described elastic pusher 72 offers spacing hole 75, described elastic pusher 72 sides are provided with electromagnet mechanism 8, described electromagnet mechanism 8 comprises bidirectional electromagnet 81, described bidirectional electromagnet 81 is provided with the iron core 82 that can inject in spacing hole 75, and bidirectional electromagnet 81 belows are fixed in telescopic elastic mechanism 9.
During centrifuge running, turn-on current in bidirectional electromagnet 81 meanwhile, iron core 82 moves and iron core head is penetrated in spacing hole 75 under magnetic fields, now elastic pusher 72 just can not be pushed, keep relative fixing with lock body fixed head 71, so left/right hook 3,4 keeps motionless, dead bolt is linked up with firmly and is hooked all the time, and door closure can not be opened.After centrifugal end, the automatic turn-on reversal electric current of bidirectional electromagnet 81, moves iron core 82 round about, and iron core 82 heads exit spacing hole 75, and now elastic pusher 72 can drive 3,4 activities of left/right hook, and door closure just can be opened.
Described telescopic elastic mechanism 9 comprises the travel(l)ing rest 91 that can move back and forth along body 1 madial wall, described travel(l)ing rest 91 middle parts are provided with fixed leg 93, the other end iron core of bidirectional electromagnet 81 is through travel(l)ing rest 91, and utilize catch 92 fixing, make it not depart from travel(l)ing rest 91, in described travel(l)ing rest 91 bottoms, drift angle place is provided with eccentric wheel 94, between described eccentric wheel 94 and travel(l)ing rest 91 bottoms and fixed leg 93, is connected with respectively eccentric extension spring 95, support extension spring 96.
The effect of eccentric wheel 94 is, when rotation is to dead point clockwise, can make travel(l)ing rest 91 move to departing from bidirectional electromagnet 81 1 sides, and travel(l)ing rest 91 other ends drive catch 92 that iron core 82 is pulled out to spacing hole 75.Unclamp after eccentric wheel 94, eccentric wheel 94 resets under eccentric extension spring 95 effects, and travel(l)ing rest 91 resets under support extension spring 96 effects simultaneously.
Embodiment 1
In order to improve the degree of control to automatic locking mechanism 7, can magnetic post 10 be installed in described left/right dead bolt 5,6 bottoms, on left/right hook 3,4, the hook sensor 11,12 relative with magnetic post 10 is installed, the control system signal of described hook sensor 11,12 and centrifuge joins.
When magnetic post 10 and hook sensor 11,12, press close to, in 11,12 outputs of magnetic fields lower draw-bar sensor, from high level, become low level.When machine detects hook sensor 11,12 while all becoming low level, illustrate that now door closure shuts completely.
In order to guarantee after accident power-off, door closure 2 can be opened safely when the centrifugal work, the technical scheme of the present embodiment is to offer artificial poke hole on described eccentric wheel 94.
Accident power-off when centrifugal work, iron core 82 positions remain unchanged, and elastic pusher 72 still can not promote, and door closure 2 keeps locking.After the centrifuge such as only having to shut down completely, utilize specific purpose tool to pass through artificial poke hole rotating eccentricity and take turns, make travel(l)ing rest 91 drive iron cores 82 to mobile in the other direction, iron core 82 heads exit spacing hole 75, just door closure 2 can be opened safely.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is also not only confined to above-described embodiment, and all technical schemes belonging under thinking of the present invention all belong to protection scope of the present invention.It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications also should be considered as protection scope of the present invention.
