Specific embodiment
The present invention is further elaborated with reference to the accompanying drawings of the specification.
As shown in Figure 1, a kind of filter membrane pallet for having defencive function against pressure to balance of the present invention, has balance on goods and services 2, pushes
And rotating mechanism, the first~bis- layer of filter membrane pallet 9,4 is further included, wherein first layer filter membrane pallet 9 is fixed on pushing and whirler
On structure, second layer filter membrane pallet 4 is fallen on first layer filter membrane pallet 9, and second layer filter membrane pallet 9 is equipped with multiple first filter membranes 10,
Filter membrane is placed on hole；Balance on goods and services is fixed on balance 1, and the diameter of balance on goods and services 2 disclosure satisfy that into second layer filter membrane
Multiple first filter membrane holes 10 on pallet 4.
In the present embodiment, first layer filter membrane pallet 9 is a disk, which is provided with multiple positioning pins 8, second layer filter membrane pallet
4 is generally round, which is provided with multiple first positioning holes 12, and first layer filter membrane pallet 9 is coaxial up and down with second layer filter membrane pallet 4
Arrangement；Positioning pin 8 coordinates with first positioning hole 12, and second layer filter membrane pallet 4 is made to be fixed on first layer filter membrane pallet 9.
First filter membrane hole 10 is set on 4 edge of second layer filter membrane pallet, and the size in hole meets less than filter membrane and lifted more than day
Disk 2.In the present embodiment, 10 outer rim edge of the first filter membrane hole makes opening form, to mitigate the weight of second layer filter membrane pallet 4,
4 middle part trepanning of second layer filter membrane pallet simultaneously, you can with loss of weight, and the screw installed on first layer filter membrane pallet 9 can be avoided.This
Outside, multiple second lightening holes 14 are laid on second layer filter membrane pallet, are distributed in middle part trepanning periphery, is i.e. loss of weight is again ventilative
Gas makes entire big pallet decline not generate very big windage.
Similarly, the present embodiment is laid with multiple first lightening holes 13 on first layer filter membrane pallet 9, and with the second lightening hole
14 quantity are identical, and position is corresponding, when so that the second layer filter membrane pallet 4 is located on first layer filter membrane pallet 9, play decline process
The middle effect for reducing windage.
The identical third layer filter membrane pallet 5 of multiple planforms has also been devised in the present invention, is laid in second layer filter membrane respectively
10 top of the first filter membrane hole of pallet 4, each third layer filter membrane pallet 5 are equipped with the second filter membrane hole 11.Each third layer filter membrane
Pallet 5 is generally sector, and the second filter membrane hole designed thereon is 2~5, to adapt to the smaller small filter membrane of diameter, the present embodiment
In the second filter membrane hole be 2.Equally, 11 outer rim edge of the second filter membrane hole makes opening form, to mitigate third layer filter membrane pallet 5
Weight.
Second layer filter membrane pallet 4 is equipped with locating shaft 3, and third layer filter membrane pallet 5 is equipped with the second location hole 15, locating shaft
3 and second location hole 15 coordinate, third layer filter membrane pallet 5 is made to be fixed on second layer filter membrane pallet 4.
The first filter membrane hole 10 on second layer filter membrane pallet 4 and 11 shape of the second filter membrane hole on third layer filter membrane pallet 5
It mutually echoes, the form and dimension in hole can guarantee that balance on goods and services 2 can pass through, and can place the filter membrane of different size, be a variety of
The fusion of shape.
The present invention combines to play the defencive function against pressure to balance by three layers of filter membrane pallet, operation principle and
Process is as follows：
Balance on goods and services 2 is fixed on balance 1, and first layer filter membrane pallet 9 is fixed in pushing and rotating mechanism, with entire system
System rotation and pushing.Positioning pin 8 is fixed on first layer filter membrane pallet 9, and positioning pin 8 plays fixed second layer filter membrane pallet 4
Effect, when such first layer filter membrane pallet 9 is rotated with system, second layer filter membrane pallet 4 can precisely rotation therewith.The second layer
Filter membrane pallet 4 is fallen by gravity on first layer filter membrane pallet 9, when first layer filter membrane pallet 9 pushes, second layer filter membrane support
Disk 4 can also lean on the active force of gravity with doing downward motion together.When needing to weigh, filter membrane pallet can integrally push
Fallen under the action of mechanism, at this moment balance on goods and services 2 is motionless, but it can across the first filter membrane hole 10 on second layer filter membrane pallet 4,
Jack up be placed on second layer filter membrane pallet 4 filter membrane (the small filter membrane 7 of such as a diameter of big filter membranes 6 of 90mm or a diameter of 47mm, so as to
Filter membrane is made to be placed on balance on goods and services 2 to weigh.Locating shaft 3 plays fixed filter membrane and fixes third layer filter membrane pallet 5
Effect.After weighing, filter membrane pallet can integrally lift, and be detached from balance on goods and services 2, and under the action of locating shaft 3, filter membrane can be accurate
True falls on initial position.But once because of certain reason, balance on goods and services 2 is not aligned in second layer filter membrane pallet 4
The heart has exceeded the range of design and is targeted by the edge in the first filter membrane hole 10 on second layer filter membrane pallet 4, at this moment descends press
Structure is opened, and the active force of pushing will be applied on balance on goods and services 2, and second layer filter membrane pallet 4 can overcome gravity certainly at this time
It is dynamic to lift, detach first layer filter membrane pallet 9 and second layer filter membrane pallet 4, allow first layer filter membrane pallet 9 pressing force without
Method continuous action is on balance 1.Learn that the part gravity of second layer filter membrane pallet 4 is not to damage balance by pressure by calculating.In this way
Just play the role of protecting balance.When the big filter membrane 6 for a diameter of 90mm that weighs, big filter membrane 6 can be placed directly in the second layer
On filter membrane pallet 9, during small filter membrane 7 if necessary to convert a diameter of 47mm that weighs, third layer filter membrane pallet 5 is passed through into locating shaft
3 and gravity under the action of be fixed on second layer filter membrane pallet 4, it is possible to small filter membrane 7 of weighing.
