Obtaining the unnecessary consumption of positive and negative electrode solution reduces, and effectively reduces experimental cost, and improves experiment effective percentage, and effectively
Experimental data precision, pass through the setting of seal and seal assembly so that the sealing between specimen holder and sample
Performance is effectively lifted.
Further, the seal is sealing ring, and its cross section is L-type.
Using above-mentioned technical proposal, seal is sealing ring, and the cross section of sealing ring is L-type so that sealing ring and cavity
Inwall and cavity end sample upper surface be in close contact, with improve to the full extent specimen holder experiment when it is close
Sealing property.
Further, the seal assembly includes the snap ring of environmental sealing part, and the snap ring is in semi-annular shape and snap ring
Inwall is in close contact with seal, and the snap ring is provided with the threaded rod for being used for clamping the conflict between snap ring and seal.
Using above-mentioned technical proposal, in the close contact between the snap ring and seal of semi-annular shape, and set on snap ring
That puts is used to clamp the threaded rod of conflict between snap ring and seal so that snap ring by threaded rod come adjust with seal it
Between conflict power, to adjust the clamping degree between snap ring and seal.
Further, the slippage slot of snap ring sliding is respectively provided with the both sides of the cavity, the slippage slot is mutually flat
Row is set.
Using above-mentioned technical proposal, the slippage slot and slippage slot slid by being provided for snap ring on the both sides of cavity
Between be arranged in parallel between each other so that snap ring slides along slippage slot.
Further, the snap ring is provided with the sliding block slid in slippage slot, and the sliding block is provided with and shaft
Screwed hole.
Using above-mentioned technical proposal, the sliding block set on snap ring and the screwed hole being arranged on sliding block so that threaded rod
When rotated, band movable slider threadingly move by pole length direction so that degree is contradicted between snap ring and seal, with the shifting of sliding block
Dynamic stroke is adjusted.
Further, one end of the threaded rod is provided with the butterfly nut contradicted with specimen holder side wall.
Using above-mentioned technical proposal, using butterfly screw, be for the ease of operator in operation, instrument can not be borrowed
Directly carry out threaded rod regulation.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model
Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but
As long as all protected in right of the present utility model by Patent Law.
Embodiment：A kind of seal assembly for the logical experiment of electricity, as shown in Figure 2, including the fixture 1 of sample 32, trying
Cavity 3 is provided with the fixture 1 of sample 32, cavity 3 is in cylinder, and fitting is provided with seal 2, the present embodiment on the port of cavity 3
In made using rubber, and the cross section of seal 2 is L-type and stepped；And the inwall of the short side fitting cavity 3 of L-type
On, long side is fitted in the surface of the fixture 1 of sample 32 so that laboratory sample is when needing detection, to increase laboratory sample and sample
