Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described further.Should be understood that following examples are only for the utility model is described but not for limiting scope of the present utility model.
Referring to Fig. 1, a kind of rotating mechanism formula door lock of centrifuge that the utility model provides, comprises body 1 and door closure 2, and 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, the technical solution of the utility model is to provide one automatically left/right to 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, and 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 Z-type elastic pusher 72 adds shock mount 73 by push pedal plate body and is formed.
For thrust being provided to described Z-type elastic pusher 72, realize automatic shutter, the technical solution of the utility model is, cylindrical contact 74 is installed in one end at described elastic pusher 72, spill spin block 75 is installed in cylindrical contact 74 bottoms, on described spill spin block 75, offer can accommodating cylindrical contact 74 groove, described spill spin block 75 drives by motor 76, realize rotation, the rotation of spill spin block 75 drives the left and right transverse shifting of Z-type elastic pusher 72 by contact 74, and then by left/right hook 3, 4 insert or leave left/right dead bolt 5, 6, realize closing or opening of body 1 and door closure 2.
As centrifugal accident power-off midway, spill spin block 75 positions remain unchanged, and Z-type elastic pusher 72 still can not promote, and door closure 2 keeps locking.After the centrifuge such as only having to shut down completely, the poke hole 77 that utilizes special tool to aim on spill spin block rotates, and makes contact 74 depart from groove position, now freely activity of Z-type elastic pusher 72, and door closure just can be opened.
Embodiment 1
In order to improve the degree of control to automatic locking mechanism 7, can dead bolt magnetic post 8,9 be installed in described left/right dead bolt 5,6 bottoms, in left/right hook 3,4, the hook sensor relative with dead bolt magnetic post 8,9 10,11 is installed; On described motor 76, be also provided with can with the left magnetic post 78 of the spill spin block of spill spin block 75 two bottom sides, spill spin block inductor 12 that the right magnetic post 79 of spill spin block is relative, described hook sensor 10,11, and spill spin block inductor 12 all joins with the control system signal of centrifuge.
Press close to when dead bolt magnetic post 8,9 and hook sensor 10,11, become low level in magnetic fields lower sensor output from high level.In the time that machine detects that left/right hook sensor all becomes low level, illustrate that now door closure shuts completely.
When motor 76 driven rotary pieces 75 rotate, in the time that spill spin block inductor 12 detects the left magnetic of spill spin block post 78, motor 76 stops the rotation, at this moment the cylindrical contact 74 on Z-type elastic pusher 72 enters the depression position of spill spin block completely, be Z-type elastic pusher 72 by locked, guarantee running in door closure surprisingly do not opened.When after normal centrifugal end, when spill spin block inductor 12 detects the right magnetic of spill spin block post 79, motor 76 stops the rotation, at this moment the protrusion position of spill spin block 75 goes to cylindrical contact 74 places, promoting contact and Z-type elastic pusher moves to left, make left/right hook depart from left/right dead bolt, door closure can be realized and automatically springing open under tension force effect.
Embodiment 2
The quantity of described Z-type elastic pusher 72 can need to be adjusted according to using, and guarantees that it can drive hook insert or leave dead bolt and can be rotated by driven by motor simultaneously.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
