Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be further described.Should be understood that following examples only for illustration of the present invention but not for limiting the scope of the invention.
See Fig. 1, a kind of Electromagnet mechanism type centrifugal machine door lock provided by the invention, comprise body 1 and door closure 2, described body 1 top is provided with left/right hook 3, 4, be provided with bottom door closure and link up with suitable left/right dead bolt 5 with left/right, 6, by left/right is linked up with 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, there is provided one automatically left/right can be linked up with 3, 4 are inserted into left/right dead bolt 5, automatic locking mechanism 7 in 6, described automatic locking mechanism 7 comprise be connected to left/right hook 3, lock body fixed head 71 bottom 4, described left/right hook 3, 4 are all hinged on lock body fixed head 71, described lock body fixed head 71 side also parallel being provided with is connected to described left/right hook 3, between 4, left/right can be driven to link up with 3, 4 insert simultaneously or leave left/right dead bolt 5, the Z-type elastic pusher 72 of 6, in the present embodiment, described elastic pusher 72 adds shock mount 73 by push pedal plate body and formed, push pedal plate body one end is arranged on and the dark cover 74 stretched out outside body 1 realizes the Level Promoting of elastic pusher 72 by pressing, spring 73 is utilized to realize resetting.
In order to ensure the stable state of elastic pusher 72 when pushing and reset, technical scheme of the present invention is, spacing hole 75 is offered at the other end of described elastic pusher 72, described elastic pusher 72 side is 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, is fixed in telescopic elastic mechanism 9 below bidirectional electromagnet 81.
During centrifuge running, meanwhile turn-on current in bidirectional electromagnet 81, iron core 82 action make iron core head penetrate in spacing hole 75 under magnetic fields, now elastic pusher 72 just can not be pushed, keep relative with lock body fixed head 71 to fix, so left/right hook 3,4 keeps motionless, dead bolt is linked up with all the time firmly to be hooked, and door closure can not be opened.When after centrifugal end, bidirectional electromagnet 81 is turn-on reversal electric current automatically, and make iron core 82 action round about, iron core 82 head exits spacing hole 75, and now elastic pusher 72 can drive left/right to link up with 3,4 activities, 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, in the middle part of described travel(l)ing rest 91, fixed leg 93 is installed, the other end iron core of bidirectional electromagnet 81 is through travel(l)ing rest 91, and utilize catch 92 to fix, it is made not depart from travel(l)ing rest 91, in bottom described travel(l)ing rest 91, drift angle place is provided with eccentric wheel 94, bottom described eccentric wheel 94 and travel(l)ing rest 91 and be connected to eccentric extension spring 95, support extension spring 96 between fixed leg 93.
The effect of eccentric wheel 94 is, when rotating to dead point clockwise, travel(l)ing rest 91 can be made to move to departing from bidirectional electromagnet 81 1 side, and travel(l)ing rest 91 other end drives catch 92 that iron core 82 is pulled out spacing hole 75.After unclamping eccentric wheel 94, eccentric wheel 94 resets under eccentric extension spring 95 acts on, and travel(l)ing rest 91 resets under support extension spring 96 acts on simultaneously.
Embodiment 1
In order to improve the degree of control to automatic locking mechanism 7, bottom described left/right dead bolt 5,6, magnetic post 10 can be installed, left/right hook 3,4 is provided with the hook sensor 11,12 relative with magnetic post 10, and described hook sensor 11,12 connects with the control system signal of centrifuge.
When magnetic post 10 and hook sensor 11,12 are pressed close to, export at magnetic fields lower draw-bar sensor 11,12 and become low level from high level.When machine detects that hook sensor 11,12 all becomes low level, illustrate that now door closure shuts completely.
Embodiment 2
In order to ensure when centrifugal work after accident power-off, door closure 2 can be opened safely, the technical scheme of the present embodiment is, artificial poke hole offered by described eccentric wheel 94.
The accident power-off when centrifugal work, iron core 82 position remains unchanged, and elastic pusher 72 still can not promote, and door closure 2 keeps locking.After the centrifuge such as only having shut down completely, utilize specific purpose tool to pass through artificial poke hole rotating eccentricity wheel, make travel(l)ing rest 91 drive iron core 82 to mobile in the other direction, iron core 82 head exits spacing hole 75, just door closure 2 can be opened safely.
The above is only the preferred embodiment of the present invention, protection scope of the present invention be not only confined to above-described embodiment, and all technical schemes belonged 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.
