To reach above-mentioned purpose, what the technical scheme of the invention was realized in:
A kind of compression type DGT overcoats, including inner core, the base provided with cavity structure and it is articulated with the outer of described base one end Lid, the cavity of the base is interior to be provided with a horizontal anomalous movement plate that can be moved in the vertical, and the lower surface of the horizontal anomalous movement plate leads to Overcompression spring is connected with the inner bottom plating of the base;The upper surface of the inner core is provided with the deep gouge to cave inward, the inner core It is arranged on the horizontal anomalous movement plate, the madial wall of the lateral wall of the inner core and the base fits;Outer cover sets There is the through hole that and size adaptable with the deep gouge is less than the deep gouge.
Further, the madial wall of the base is provided with multiple longitudinal chutes, the side wall of the horizontal anomalous movement plate and The sliding block being adapted with the chute is equipped with the lateral wall of the inner core.
Further, the inner face of the enclosing cover is provided with sealing gasket.
Further, the enclosing cover is fixed by latching with the base.
Further, the cross section of the base, the enclosing cover and the inner core is circle.
Further, the deep gouge is circular deep gouge, and the outer through hole covered is manhole.
Further, the material for stating inner core, the base, the enclosing cover and the portable plate is ABS engineering plastics.
Relative to prior art, a kind of compression type DGT overcoats described in the invention have the advantage that:
(1) base intracavity of the DGT overcoats described in the invention is provided with can move in the vertical by compression spring control Dynamic portable plate, inner core are positioned on portable plate, and user can set diffusion phase and the combination of different-thickness according to actual conditions Mutually in the deep gouge on inner core, compression spring can adjust under the pressure of enclosing cover, applied widely, reusable, together When due to the effect of compression spring, inner core can seal by filter membrane, diffusion mutually and with reference to mutually closely be attached on enclosing cover inner face It is functional;
(2) the base madial wall described in the invention is provided with longitudinal chute, is equipped with portable plate and inner core with sliding The adaptable sliding block of groove, can prevent inner core from being rotated in base, fix the position of inner core, while can ensure inner core With portable plate when enclosing cover covers downwards, can smoothly it be moved down in the presence of enclosing cover pressure.
