Description
[technical field]
This utility model relates to a kind of observation window baffle plate, specifically this utility model and relates to a kind of Vacuum Magnetic observation window
Baffle plate.
[background technology]
Known, traditional baffle mechanism is to be driven observation window baffle plate to rotate, due to damper shaft by handwheel by damper shaft
Side is vacuum, it is common that use on bearing a pair O RunddichtringO to reach sealing effectiveness, but the sealing of O RunddichtringO
Limited in one's ability, it is impossible to for ultrahigh vacuum seal, gas leakage of easily wearing and tearing, and need running check and replacing, must weigh after replacing
New leak detection could use, thus adds the workload of professional.
[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses a kind of Vacuum Magnetic observation window baffle plate, it is achieved
Under ultra-high vacuum environment, arbitrarily rotate observation window baffle plate and do not affect vacuum, allow rotation observation window guard seal become peace
Entirely, zero leak rate, the purpose of frangible seal part need not be changed.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of Vacuum Magnetic observation window baffle plate, including baffle plate, observation window assembly and rotating shaft, arranges peace on observation window assembly
The hole of dress rotating shaft, is provided with the groove placing Magnet set in the bottom of observation window assembly, Magnet set bottom be provided with and pass through spiral shell
The fixing Magnet gland connected of nail, is provided with inner sleeve between rotating shaft and observation window assembly, the bottom of inner sleeve and Magnet set upper side
It is provided with magnetic piece A between catch, between the bottom and the bottom of inner sleeve of rotating shaft, is provided with magnetic piece B.
Described Vacuum Magnetic observation window baffle plate, described inner sleeve is connected with observation window components welding, in inner sleeve top
Wall is provided with step, is provided with axle bumper block between step and the top of rotating shaft.
Described Vacuum Magnetic observation window baffle plate, the top of described rotating shaft is set to screw mandrel, is provided with and passes through spiral shell on screw mandrel
Female fixing baffle plate.
Owing to have employed technique scheme, this utility model has a following superiority:
This utility model, by placing strip magnetic piece B7 and magnet A 5 in inner sleeve 9 and outside inner sleeve 9 respectively, utilizes Magnet
Active force rotates observation window baffle plate rotating shaft, and described inner sleeve 9 is welded to connect with observation window assembly 3, there is not leakage point, thoroughly solves
The problems such as conventional seals of having determined mode easily gas leakage, are applicable not only under high vacuum environment use, but also are applicable to ultrahigh vacuum
Use under environment；This utility model is long for service life, and is not related to the consumable accessorys such as sealing ring.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model；
In the drawings: 1, baffle plate；2, axle bumper block；3, observation window assembly；4, rotating shaft；5, magnetic piece A；6, Magnet set；7, magnetic piece B；
8, Magnet gland；9, inner sleeve；10, catch.
[detailed description of the invention]
Can be explained in more detail this utility model by the following examples, this utility model is not limited to following
Embodiment；
In conjunction with the Vacuum Magnetic observation window baffle plate described in accompanying drawing 1, Vacuum Magnetic observation window baffle plate, including baffle plate 1, observation window
Assembly 3 and rotating shaft 4, the top of described rotating shaft 4 is set to screw mandrel, is provided with the baffle plate 1 fixing by nut on screw mandrel；Observing
The hole installing rotating shaft 4 is set on window assembly 3, is provided with the groove placing Magnet set 6 in the bottom of observation window assembly 3, overlaps 6 at Magnet
Bottom be provided with the Magnet gland 8 being fixed connection by screw, between rotating shaft 4 and observation window assembly 3, be provided with inner sleeve 9, interior
The bottom of set 9 and Magnet overlap and are provided with magnetic piece A5 between the catch 10 of 6 upper ends, set between the bottom of the bottom of rotating shaft 4 and inner sleeve 9
There is magnetic piece B7；Described inner sleeve 9 is welded to connect with observation window assembly 3, is provided with step on the inwall on inner sleeve 9 top, step with
Axle bumper block 2 it is provided with between the top of rotating shaft 4.
Implement Vacuum Magnetic observation window baffle plate described in the utility model, in use, rotary magnet gland 8, drive magnetic
Ferrum A5 moves, and magnet A 5 attracts magnet B 7 to move, and magnet B 7 drives rotating shaft 4 and baffle plate 1 to move, it is achieved that switch baffle plate 1 flexibly
Purpose, and inner sleeve 9 is welded to connect with observation window assembly 3, there is not leakage point, thoroughly solves conventional seals mode and easily leak gas
Etc. problem, it is applicable not only under high vacuum environment use, but also is applicable under ultra-high vacuum environment use；This utility model makes
Use the life-span long, and be not related to the consumable accessorys such as sealing ring.
The non-detailed portion of this utility model is prior art.
The embodiment selected in this article to disclose goal of the invention of the present utility model, it is suitable to be presently considered to be,
However, it should be understood that, this utility model is intended to include that all belong to the institute of the embodiment in the range of this design and utility model
