Abstract
The utility model discloses a centrifuge cover locking mechanism of convenient operation, which comprises a centrifuge shell and at least two observation boards arranged on the upper surface of the centrifuge shell. A groove is arranged on each observation board. A pressing column is movably sheathed in the centrifuge shell. A fixing guide column which acts on the pressing column is matched in the groove. Through applying acting force to the pressing column, the pressing column moves up and down and drives the fixing guide column to move up and down and to enter or leave the groove on the observation board, thereby reaching the goal of locking or detaching the observation boards. In the process, the up-and-down movement of the pressing column can be realized through manually pressing down the pressing column or pulling the pressing column. Thereby, the damages or inconvenient operation caused by used threads are avoided, the operation reliability is improved and the centrifuge cover locking mechanism can be widely popularized and applied.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 2, Fig. 3 and shown in Figure 4, centrifuge cup retaining mechanism of the present utility model, the at least two lobe access panels 5 that comprise centrifuge shell 7 and be arranged on centrifuge shell 7 upper surface places, on every lobe access panel 5, be provided with groove 18, in centrifuge shell 7, be movably installed with compression leg 1, be combined with the fixedly guide pillar 9 that acts on the compression leg 1 in the groove 18.During work,, compression leg 1 is moved up and down, move up and down and enter or leave groove 18 on the access panel 5 thereby drive fixing guide pillar 9 by applying active force on compression leg 1, thus the purpose that reaches locking or separate access panel 5.In this process, moving up and down of compression leg 1 can be by pressing down compression leg 1 or pulling compression leg 1 is realized manually, thereby avoid damage or the operation inconvenience of adopting screw thread to bring, improved the reliability of operation.Access panel 5 in this embodiment preferably only is provided with two lobes, and fixedly guide pillar 9 the form on the compression leg 1 of acting on can be fixing guide pillar 9 to be directly connected to move up and down with compression leg 1 on the compression leg 1, as optimal way, compression leg 1 is provided with push pedal 8, fixedly guide pillar 9 is fixedly connected in the push pedal 8, can be beneficial to the processing and manufacturing of compression leg 1.
In the above-described embodiment, for ease of finishing the operation that moves up and down, between centrifuge shell 7 and compression leg 1, be provided with the flexible member 6 of vertical layout to compression leg 1.In pulling or press down compression leg 1 when making fixing guide pillar 9 leave groove 18 on the access panel 5, flexible member 6 can make compression leg 1 automatically reset.This flexible member 6 can adopt elastic caoutchouc or spring, preferably adopts spring.
In the above embodiment, groove 18 can be arranged on the upper surface place of access panel 5, at this moment, fixedly guide pillar 9 is arranged between the groove 18 of the top of compression leg 1 and access panel 5, and flexible member 6 can be arranged between the lower surface of the bottom of compression leg 1 and access panel 5, when then needing to separate access panel 5, can move up by pulling compression leg 1 and make fixedly that guide pillar 9 leaves groove 18, access panel 5 be separated, at this moment, unclamp compression leg 1, compression leg 1 and fixing guide pillar 9 are resetted.And as optimal way, described groove 18 is arranged on the bottom surface of access panel 5, and push pedal 8 is arranged on the bottom of compression leg 1 and is positioned at centrifuge shell 7 belows, and fixedly guide pillar 9 passes centrifuge shell 7 and is coupled in the groove 18.Then when separating access panel 5, can make fixedly that guide pillar 9 leaves groove 18 by pressing down compression leg 1, after fixedly guide pillar 9 leaves groove 18 fully, can be separately with access panel 5, unclamp the pressure that is applied on the compression leg 1 then, compression leg 1 and fixing guide pillar 9 are resetted under the effect of flexible member 6; And in locking during access panel 5, earlier with compression leg 1 toward pressing down, after access panel 5 complete closures are held together, decontrol compression leg 1, guide pillar 9 is inserted in the groove 18 access panel 5 is locked, this mode of operation is more reasonable, makes the reliability raising.
In the above-described embodiment, compression leg 1 can be fixedly connected in the push pedal 8, and as optimal way, in described compression leg 1 movable set and the push pedal 8, compression leg 1 is provided with the first step 19 that is engaged in push pedal 8 upper surface places, the compression leg 1 at push pedal 8 lower surface places is provided with pin 10, and this mode can be convenient to compression leg 1 disassembled from push pedal 8 and safeguard.
For ease of moving up and down of compression leg 1, in centrifuge shell 7, be set with fairlead 3, compression leg 1 is set in the fairlead 3, and the compression leg 1 that is positioned at fairlead 3 is provided with second step 20, and flexible member 6 is arranged between the bottom and second step 20 of fairlead 3.Then pressing down compression leg 1 and compression leg 1 when under the effect of flexible member 6, upwards resetting; all be in fairlead 3, to move to finish; can effectively avoid causing the jam of compression leg 1; and flexible member 6 is arranged between the bottom and second step 20 of fairlead 3,3 pairs of these flexible members 6 of fairlead are effectively protected.
Be the better reliable lock that improves access panel 5, fixedly guide pillar 9 is provided with alignment pin, and fairlead 3 is provided with suitable and be the stopper slot 13 of bending structure with alignment pin.Its structure as shown in Figure 4, when access panel 5 was closed, alignment pin was in operating position 16 among Fig. 4; When opening access panel 5, at first rotate compression leg 1, alignment pin is rotated to treat open position 15, this moment just can be with compression leg 1 by to open position 17 access panel 5 being opened; Otherwise, when closing access panel 5, treat fixedly guide pillar 9 locking access panels 5 after, rotation compression leg 1 makes alignment pin move to operating position 16 from treating open position 15, thereby can prevent maloperation, effectively improves the reliability of retaining mechanism.
Closed and locked for ease of access panel 5, the place, lower edge that the top of described fixedly guide pillar 9 and access panel 5 are coupled to compression leg 1 is wedge structure.Then when closing access panel 5, the wedge structure of access panel 5 affacts on the wedge structure on fixing guide pillar 9 tops, compression leg 1 is down moved, after access panel 5 complete closures were held together, fixedly guide pillar 9 upwards was inserted under the effect of flexible member 6 in the groove 18 access panel 5 lockings.This version can avoid making fixedly toward pressing down compression leg 1 once more, and guide pillar 9 is inserted in the groove 18, and is easy to operate.
After fixedly guide pillar 9 leaves groove 18, can open automatically for making access panel 5, between adjacent two lobe access panels 5, be provided with back and try hard to recommend bar 11.After then fixedly guide pillar 9 left groove 18, access panel 5 was tried hard to recommend bar 11 in this time and can be automatically springed open, and had improved the separately reliability of access panel 5.
In order in the process of pressing down, to improve protective effect to compression leg 1 and fairlead 3, be provided with clossing pressure plate 2 at fairlead 3 tops, compression leg 1 is sleeved in the clossing pressure plate 2; Simultaneously, close up for ease of the access panel 5 with flap, access panel 5 is provided with closed post 4, then closes up in the process, and available hand propelled should get final product by closure post 4.
