Close new DGT devices.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way：
A kind of DGT overcoats of high leakproofness, including base and the closure that is hinged with base one end, base are provided with first
Groove, the first groove periphery is provided with one annular groove；Closure is provided with and size corresponding with the first groove less than first
The through hole of groove, is additionally provided with the sealing projection matched with annular groove on closure.
Further, the base is provided with locking device with closure side relevant position.
Further, the locking device includes the second groove on the base and the card on closure
Button.
Further, the locking device is hasp.
Further, the base is identical with the size of closure.
Further, the sealing projection is that silicagel pad seals projection or surface is provided with the sealing projection of silicagel pad.
Further, the base is the base being made of ABS engineering plastics, and closure is using ABS engineering plastics
The closure being made.
Further, first groove is circle with the through hole.
Relative to prior art, a kind of DGT overcoats of high leakproofness of the present invention have the advantage that：
A kind of DGT overcoats of high leakproofness of the present invention, by annular groove and the setting of sealing projection, realize
The sealing of DGT devices, while setting the sealing that silicagel pad further increases device in sealing lug surface；The device sets
Meter is simple, assembles simple and convenient, low cost, can Reusability.

To express or implicitly include one or more this feature.In the description of the invention, unless otherwise indicated, " multiple "
It is meant that two or more.
In the description of the invention, it is necessary to illustrate, unless otherwise clearly defined and limited, term " installation ", " phase
Company ", " connection " should be interpreted broadly, for example, it may be being fixedly connected, or being detachably connected, or be integrally connected；Can
Being to mechanically connect, or electrically connect；Can be joined directly together, it is also possible to be indirectly connected to by intermediary, Ke Yishi
Two connections of element internal.For the ordinary skill in the art, above-mentioned term can be understood by concrete condition
Concrete meaning in the present invention.
Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of DGT overcoats of high leakproofness, as shown in Figure 1 and Figure 2, including base 1 and the sealing that is hinged with the one end of base 1
Lid 2, base 1 is provided with the first groove 3, and the periphery of the first groove 3 is provided with one annular groove 4；Closure 2 is provided with and the first groove
3 corresponding and sizes are additionally provided with the sealing projection matched with annular groove 4 less than the through hole 5 of the first groove 3 on closure 2
6。
Base 1 is provided with locking device with the side relevant position of closure 2.Locking device is favorably improved the sealing of device
Property.
Locking device includes the second groove on base 1 and the buckle on closure 2.
Locking device is hasp.
Base 1 is identical with the size of the closure 2.
Sealing projection 6 is that silicagel pad seals projection or surface is provided with the sealing projection of silicagel pad.Silicagel pad is favorably improved
The sealing of device.
Base 1 is the base being made of ABS engineering plastics, and closure 2 is the sealing being made of ABS engineering plastics
Lid.ABS engineering plastics have fabulous impact strength, good stability of the dimension, wearability, chemical proof.
First groove 3 is circle with through hole 5.In the present embodiment, through hole 5 is concentric with the first groove 3, and through hole 5
Radius is less than the radius of the first groove 3, therefore the radius of through hole 5 is less than the radius for combining phase, diffusion phase and filter membrane, through hole 5
The top with reference to phase, diffusion phase and filter membrane is pressed in, the sealing of device is enhanced.
The specific workflow of this example is as follows：
First DGT solid bonds phase, diffusion are mutually laid in the first groove 3 successively with filter membrane, then closure 2 is covered
On base 1 so that sealing projection 6 is just stuck in the first groove 3, through hole 5 is pressed in combination phase, diffusion in the first groove 3
Mutually and on filter membrane, then locked by locking device；The wind desiceted soil 50.0g of 2mm sieves was weighed, was put into plastic containers, made
Soil thickness is 1.5cm, and addition ultra-pure water causes that water capacity to be measured reaches 60%, and 48h is balanced after sealing, then adds again
Plus ultra-pure water causes that the water-holding capacity in soil to be measured reaches 100%, balances 24h so that soil is in grume and surface is smooth；With
A small amount of soil to be measured is gently applied to the filtering film outer surface appeared at the through hole 5 of closure 2, is gently reversed with hand, and this is filled
Put the surface of press-in soil, it is ensured that the present apparatus and soil contact are good, immediate record time and environment temperature；It is fast after placing 24h
Speed takes out the present apparatus, will add 1mL1mol L with reference to 1.5mL centrifuge tubes are mutually placed in-1HNO3, it is ensured that with reference to phase quilt completely
HNO3Submergence, dilutes to be measured after placing 24h.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
