", namely lid switch 3 correspondence unlocks some position, represents that now centrifuge is still in open mode, does not lock completely.
Step 2:
As shown in Figure 3, dextrorotation hub cap switch 3, " hand designations " sensing "
", i.e. lid switch 3 corresponding locking point position, represents now centrifuge still locking state.
As shown in Figure 9, now contact 10 has touched microswitch 11, and electrical signal transfer, to main frame, shows that centrifuge can carry out the work of High Rotation Speed.Now spacer pin 14 has been positioned at the extreme position on the left side, and spacer pin 14 can not move up and down as seen in Fig., if namely press gland switch 3 downwards in this operating condition, lid switch module can not move down, and access panel assembly 2 can not be opened.Namely the centrifuge of High Rotation Speed does not have the risk causing personal injury.
Step 3:
After collection completes, be rotated counterclockwise lid switch 3, now " hand designations " sign sensing "
", represent that now centrifuge is still in open mode, now spacer pin 14 position is positioned at the centre position of groove, and as shown in Figure 7, and now contact 10 does not touch microswitch 11.
Step 4:

Anti-misoperation designs:
Centrifuge is the equipment of High Rotation Speed, if centrifuge is not locked and just to be started working or centrifuge access panel assembly in the process of High Rotation Speed flicks suddenly when maloperation, that just exists great security risk.
1, due to the existence of the lasting thrust of thrust contact, put in place if access panel assembly is closed, access panel assembly can be open, and does not therefore also just exist to seem that to fasten the people actually do not fastened be misjudgment.And, as shown in Figure 10, access panel assembly does not close up completely, namely lock the lock slots 21 that contact 6 does not enter access panel assembly 2 completely, if operating personnel think that access panel assembly 2 has been locked thus swivelling cover switch 3, want to allow lid switch contact 10 touch microswitch 11, but at this moment spacer pin 14 is in the position that in spacing guide pad 15, relative level cavity 151 is on the lower side, can not be rotated, namely contact 10 can not touch microswitch 11, and centrifuge also can not rotary work.
2, when under the duty of centrifuge at High Rotation Speed, operating personnel think that centrifuge stops by mistake, and press gland switch 3, but the limited guide pad 15 of spacer pin 14 blocks, can not move up and down, namely lid switch module can not down vertically movement, and access panel assembly 2 can not flick suddenly.
When under the duty of centrifuge at High Rotation Speed, operating personnel think that centrifuge stops by mistake, and rotary gland switch 3, allow " hand designations " of lid switch 3 to indicate to point to "
", namely contact 10 can depart from microswitch 11, and when microswitch 11 is not triggered, centrifuge can brake immediately and report to the police, and reduces risk.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
