Referring to fig. 1 to 3, according to an aspect of an embodiment of the present invention, a socket assembly 100 is provided, which includes a barrel 10 and a rod 20. The cylinder 10 includes a sidewall 11, an accommodating space 12 enclosed by the sidewall 11, and a first opening 13 and a second opening 14 communicating with the accommodating space 12. The rod 20 is connected to the barrel 10, and the rod 20 includes a pressing rod 21 and a pressing head 22. The pressing rod 21 is disposed at a side of the first opening 13 close to the accommodating space 12, and at least a portion of the pressing rod 21 extends out of the accommodating space 12 through the second opening 14. The pressing head 22 includes a pressing plate 221 and a connector 222 connected to the pressing plate 221, the pressing plate 221 is disposed on a side of the first opening 13 away from the receiving space 12 and covers the first opening 13, and the connector 222 is connected to the pressing rod 21.

When the sleeve assembly 100 of the embodiment of the present application is used in a graphite crucible, the cylinder 10 can be connected to the opening of the graphite crucible in a sealing manner, which is equivalent to increase the height of the graphite crucible, and is used for preventing liquid iron slag from splashing onto the corundum furnace tube.

The material of the cylinder 10 may be steel, cast iron, bronze, brass, etc., and in the present embodiment, the cylinder 10 is preferably made of graphite, which is the same as the material of the graphite crucible, and has excellent chemical stability and good machinability, so that it is easy to machine the cylinder into a desired shape.

The side walls 11 enclose a receiving space 12, and in the embodiments of the present application, the cross-sectional shape of the side walls 11 may be circular, square, rectangular, diamond, etc., and may be specifically selected according to the shape of the top opening of the graphite crucible.

The accommodating space 12 accommodates the swage portion 21. Meanwhile, the housing space 12 may serve as a discharge passage for the reaction gas, and when a droplet experiment is performed using the sleeve assembly 100, the gas generated in the graphite crucible passes through the first opening 13 and the housing space 12 in this order and is discharged through the second opening 14.

The first opening 13 is disposed opposite to the opening of the graphite crucible, and the shape of the first opening 13 may be the same as the opening of the graphite crucible in order to ensure the tightness and sealing property of the connection between the cylindrical body 10 and the graphite crucible.

The second opening 14 may be disposed opposite to the first opening 13, and in the case where the second opening 14 is disposed opposite to the first opening 13, the cylinder 10 may be formed in a straight cylinder shape. In some embodiments of the present application, the second opening 14 may be disposed to be offset from the first opening 13.

It should be noted that, the second opening 14 and the first opening 13 are arranged in a staggered manner, and a plane where the first opening 13 is located may be parallel to a plane where the second opening 14 is located, but an orthographic projection of the first opening 13 to the plane where the second opening 14 is located does not completely overlap with the second opening 14; it is also possible that the plane in which the first opening 13 is located intersects the plane in which the second opening 14 is located.

The position of the first opening 13 and the position of the second opening 14 can be adjusted according to the experiment requirement by the cylinder 10, so as to realize different experiment functions, such as further avoiding splashing of liquid iron slag or conveniently collecting reaction gas. Correspondingly, under the condition that the first opening 13 and the second opening 14 are arranged in a staggered manner, the press rod part 21 should be specially designed, so that the press rod part 21 is perpendicular to the plane of the first opening 13 at the first opening 13.

In the stage of placing the sleeve assembly 100 into the graphite crucible, the rod pressing part 21 is used for matching with the head pressing part 22 to tightly clamp the cylinder 10, and the rod pressing part 21 is used for clamping the cylinder 10 into the opening of the graphite crucible, so as to prevent high-temperature gas from hurting experimenters; in the process of carrying out the molten drop experiment, the position of the pressure head part 22 can also be adjusted by the pressure rod part 21, so that the pressure head part 22 is pressed on the reaction slag iron, and the tightness of the reaction slag iron is ensured.

The pressing plate 221 is disposed on a side of the first opening 13 far from the accommodating space 12 and covers the first opening 13, and may be implemented by setting a cross-sectional area of the pressing plate 221 to be larger than a size of the opening of the first opening 13, or may be configured by setting a clamping groove or a clamping ring to clamp the pressing plate 221 in the first opening 13, so as to limit the pressing plate 221 to carry into the accommodating space 12 along the axial direction of the barrel 10.

The connector 222 and the pressure lever portion 21 may be fixedly connected by riveting, bonding, integral molding, or detachably connected by screwing, and may be selected according to the specific requirements of the droplet experiment, which is not limited in this application.

In some embodiments of the present application, the stake portion 21 falls completely within the first opening 13 in an orthographic projection of the baffle 15.

That is to say, the cross-sectional area of the rod pressing part 21 is smaller than the opening area of the first opening 13, so that the rod pressing part 21 can freely pass through the first opening 13, after the cylinder 10 is connected with the graphite crucible, an experimenter can drive the press head part 22 to move along the axial direction through the rod pressing part 21, and press the iron slag tightly by the press head part 22, thereby ensuring the normal operation of the experiment.
