An object of the utility model is to provide a simple structure, simple operation and can make middle container and supporting device of the manual descending of piston to the not enough of existence among the prior art.
The utility model provides a technical scheme that above-mentioned technical problem adopted is: a piston manual falling type intermediate container and a matching device thereof comprise an intermediate container and a hydraulic device, wherein the intermediate container comprises a cylinder body, an upper container cover, a lower container cover and a piston, the upper container cover and the lower container cover are respectively provided with an exhaust valve and a displacement valve, a hydraulic plunger is arranged in the middle of the upper container cover, and an annular limiting groove is formed in the upper container cover; the hydraulic device comprises a hydraulic guide pipe, a pressure rod, a liquid storage chamber, a vent valve, a control knob, a one-way valve and a hydraulic base, and is connected with the middle container through the hydraulic guide pipe.
Furthermore, four limiting slips are arranged on the cylindrical surface of the hydraulic plunger, are uniformly distributed along the cylindrical surface of the hydraulic plunger, and are downward in direction.
Furthermore, the size and the depth of the annular limiting groove are matched with the size of the limiting slip.
Furthermore, a container bracket is arranged at the lower part of the middle container, and the whole middle container is arranged on the base bracket.
The utility model discloses need not link to each other middle container and gas cylinder, use hydraulic means, through hydraulic pressure plunger with the manual piston that pushes away to middle container lower part, simple structure, convenient operation have improved the stability and the security of middle container in the experimentation.

Detailed Description
The present invention will be further specifically described with reference to the accompanying drawings and examples.
As shown in fig. 1-3, a piston manual-drop type intermediate container and a matching device thereof comprise an intermediate container and a hydraulic device, wherein the intermediate container comprises a cylinder body 1, an upper container cover 2, a lower container cover 3 and a piston 5, the upper container cover 2 and the lower container cover 3 are respectively provided with an exhaust valve 16 and a displacement valve 17, the middle of the upper container cover 2 is provided with a hydraulic plunger 6, the hydraulic plunger 6 is provided with a limiting slip 14, an annular limiting groove 15 is arranged inside the upper container cover 2, and the size and the depth of the limiting groove 15 are matched with the size of the limiting slip 14; the hydraulic device comprises a hydraulic conduit 7, a pressure lever 8, a liquid storage chamber 9, a vent valve 10, a control knob 11, a one-way valve 12 and a hydraulic base 13, and the hydraulic device is connected with the intermediate container through the hydraulic conduit 7.
in the preferred embodiment of the hydraulic device, the control knob 11 controls the communication between the reservoir 9 and the hydraulic conduit 7, the vent valve 10 controls the communication between the reservoir 9 and the outside atmosphere, the pressure rod 8 can be artificially lengthened, and the check valve 12 controls the flow direction of the liquid. After the core displacement experiment is finished, the control knob 11 is closed, the vent valve 10 is opened, the pressure lever 8 is manually lifted and pressed down, liquid in the liquid storage chamber 9 is pressed into the hydraulic guide pipe 7 through the one-way valve 12, the hydraulic plunger 6 is pushed to move downwards, and meanwhile, the hydraulic plunger 6 pushes the piston 5 to move downwards until the piston 5 is pushed to the lower part of the middle container. After the middle container is refilled to start the core displacement experiment, the control knob 11 and the vent valve 10 are opened, the piston 5 can also push the hydraulic plunger 6 to move upwards in the upward movement process, the liquid in the upper space of the hydraulic plunger 6 is pressed into the liquid storage chamber 9 along the hydraulic conduit 7 until the hydraulic plunger 6 is completely retracted, and the core displacement experiment is finished.
As shown in FIG. 3, the preferred installation mode of the limiting slips 14 is that four limiting slips 14 are evenly arranged on the upper part of the cylindrical surface of the hydraulic plunger 6, and all the limiting slips 14 are downwards directed. When the hydraulic plunger 6 moves downwards to the annular limiting groove 15 in the upper container cover 2, the limiting slips 14 are clamped in the annular limiting groove 15 to prevent the hydraulic plunger 6 from falling off from the upper container cover 2, and when the hydraulic plunger 6 moves upwards, the limiting slips 14 are gradually withdrawn until completely separating from the annular limiting groove 15.
In order to facilitate the placement of the intermediate container, it is preferred that the lower container cover 3 is provided with a container holder 4 at a lower portion thereof, and the entire intermediate container is mounted on the container holder 4.
