The technical scheme that its technical problem that solves the utility model adopts can also be further perfect.
Lifting clamping device described in the utility model comprises elevating lever, lifting support, compression axis and roller, and wherein compression axis and roller are fixedly connected on the elevating lever, has on the lifting support with roller to be the chute that is slidingly matched; Have slanting wedge hole on the lift hermatic door, compression axis and slanting wedge hole are wedge shape and are slidingly matched; Also can adopt other forms of lifting device.
Slanting wedge hole described in the utility model is the through hole that is formed by connecting with level two semicircles at an angle, also can adopt the wedge fit structure of other form.
The inwall that one end of screw guide pillar described in the utility model passes the hermatic door framework is inserted in the perforate that the floating seal doorframe is provided with, and the floating seal doorframe is by this perforate and screw guide pillar 6 and is connected.
The effect that the utility model is useful is: owing to adopted lifting clamping device, make hermatic door and vacuum chamber realize floating seal, when vacuum chamber formed negative pressure, sealing effectiveness strengthened; When vacuum chamber formed malleation, hermatic door relied on the double-screw bolt self-locking seal.Like this, the positive-negative voltage pulse circulation time all can be realized sealing in the vacuum chamber, promptly in the vacuum chamber, no matter is in positive and negative pressure, and hermatic door all can be realized soft seal, and good sealing effect, speed of response are fast.
Description of drawings
Fig. 1 is the utility model master TV structure synoptic diagram;
Reference numeral: compression axis 1, hermatic door framework 2, feed cavity 2-1 compress working chamber 2-2, floating seal doorframe 3, sealed strip 4, lift hermatic door 5, slanting wedge hole 5-1, screw guide pillar 6, vacuum chamber 7, through hole 8, elevating lever 9, lifting support 10; Chute 10-1, roller 11.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, this soft sealer for vacuum chamber mainly comprises vacuum chamber 7, is fixedly connected with hermatic door framework 2 on the described vacuum chamber 7, hermatic door framework 2 comprises the feed cavity 2-1 that is connected and compresses working chamber 2-2, compresses working chamber 2-2 and be connected with vacuum chamber 7 by through hole 8; Be provided with floating seal doorframe 3 in the working chamber 2-2 compressing of through hole 8 places, but the outside of floating seal doorframe 3 is provided with the lift hermatic door 5 of oscilaltion, this lift hermatic door 5 is connected with lifting clamping device; Floating seal doorframe 3 floats with hermatic door framework 2 by one group of screw guide pillar 6 and connects, the inwall that one end of screw guide pillar 6 passes hermatic door framework 2 is inserted in the perforate that floating seal doorframe 3 is provided with, and floating seal doorframe 3 is by this perforate and screw guide pillar 6 and is slidingly matched.Sealed strip 4 is embedded in the groove of floating seal doorframe 3 and lift hermatic door 5.
Lifting clamping device described in the utility model comprises elevating lever 9, lifting support 10, compression axis 1 and roller 11, and wherein compression axis 1 and roller 11 are fixedly connected on the elevating lever 9, and elevating lever 9 links to each other with electric face by gear, tooth bar; Have on the lifting support 10 with roller 11 and be the chute 10-1 that is slidingly matched; Have slanting wedge hole 5-1 on the lift hermatic door 5, compression axis 1 is wedge-like engagement with slanting wedge hole 5-1 and is connected, and slanting wedge hole 5-1 is the through hole that is formed by connecting with level two semicircles at an angle.
