[0003] In the prior art, for example, a prefabricated graphite sagger proposed in Chinese patent publication number CN219037616U has a side plate and a bending portion as an integrated structure, and a bottom plate and a convex strip as an integrated structure, so that when assembling, it is only necessary to connect a plurality of side plates and a bottom plate with screws, and it is no longer necessary to consider the splicing process between the bottom plate and the horizontal graphite square column, the side plate and the vertical graphite square column, and the side plate and the horizontal graphite square column. However, the above technical solution still has the following problems:

[0004] The applicant believes that the side plates and the bottom plate are fixed by screws, and the bottom plate and the side plates are spliced ​​in a close manner, which causes an installation offset between the side plates and the bottom plate, and it is easy to cause the gap between the side plates and the bottom plate to increase, and the liquid in the graphite sagger is easy to flow out of the gap, which will affect the experiment. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a combined graphite sagger, which solves the problem that the liquid in the graphite sagger easily flows out from the gap when the bottom plate and the side plate are spliced ​​in a close manner.

[0006] To achieve the above-mentioned purpose, according to an embodiment of the utility model, a combined graphite sagger is proposed, comprising a bottom plate, an inner frame is fixedly installed on one side of the bottom plate, a built-in groove is provided on the side of the inner frame away from the center of the bottom plate, an airbag is provided in the built-in groove, a convex strip is provided on the top of the airbag, a graphite sealing strip is provided on one side of the side plate, and an arc groove is provided at the bottom end of the graphite sealing strip, which is squeezed and displaced with the convex strip.

[0007] Preferably, the convex strip and the arc groove are offset from each other, and the convex strip is located at the lower part of the arc groove.

[0008] Preferably, the inner wall of the built-in groove is wavy.

[0009] Preferably, a pressing block for pressing the airbag is provided on one side of the side plate.

[0010] Preferably, the graphite sealing strip is L-shaped.

[0011] Preferably, a mounting side block is fixedly mounted on one side of the side plate, and the mounting side block is fixed to the bottom plate and the adjacent side plate.

[0013] Preferably, the bottom ends of the side plates are fixedly connected to mounting bottom blocks, and the mounting bottom blocks and the bottom plate are fixed to each other.

[0014] Preferably, a mounting groove is formed on a side of the side plate away from the mounting side block, and a sealing gasket engaging with the mounting groove is provided on one end of two adjacent side plates facing each other.

[0015] Preferably, the mounting groove is in a convex shape.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] By arranging the airbag, the convex strip, the graphite sealing strip and the arc groove, and by assembling the side panels to the sides of the bottom panel in sequence, and fixing the mounting bottom block to the bottom panel by screws, the side panel drives the extrusion block to squeeze the airbag, and the airbag drives the convex strip to inflate after being compressed, and the convex strip squeezes the side wall of the arc groove, so that the graphite sealing strip slides relatively due to the compression of the arc groove, and the graphite sealing strip is further pressed against the gap between the inner frame and the side panel, thereby improving the sealing effect and reducing the outflow of liquid from the gap. The whole assembly is simple and easy to replace.

[0018] By setting a sealing gasket, an installation groove is opened on one side of the side panel, and both the installation groove and the sealing gasket are convex in shape to facilitate snap-in, thereby improving the fit between the sealing gasket and the installation groove and reducing offset. Screws are used to sequentially penetrate the installation side block, the sealing gasket and the installation groove, so that the sealing gasket is installed between two adjacent side panels to improve the sealing effect between the side panels.

When the side panel 2 is installed on the bottom panel 1, the graphite sealing strip 9 is L-shaped, and the top end is placed on the surface of the inner frame 5. The convex strip 8 and the arc groove 11 are offset from each other, and the convex strip 8 is located at the lower part of the arc groove 11. When the extrusion block 10 pushes the airbag 7, the air of the squeezed part gradually flows to the convex strip 8, and the convex strip 8 squeezes the arc groove 11. Due to the relative offset between the arc groove 11 and the convex strip 8, and the convex strip 8 is located at the lower part of the arc groove 11, the convex strip 8 drives the graphite sealing strip 9 to move gradually downward through the arc portion of the arc groove 11, and the graphite sealing strip 9 presses the gap between the side panel 2 and the inner frame 5 more tightly. The graphite sealing strip 9 further increases the gap between the inner frame 5 and the side panel 2 to achieve a sealing effect to reduce the outflow of liquid from the gap.

[0027] As an implementation method in this embodiment, Figure 1As shown, a mounting side block 3 is fixedly installed on one side of the side panel 2, and mounting holes are provided on the bottom end and side wall of the mounting side block 3. The mounting holes at the bottom end of the mounting side block 3 are fixed to the bottom plate 1 by screws, and the mounting holes on the side wall of the mounting side block 3 are fixed to the two adjacent side panels 2 by screws. The bottom ends of the side panels 2 are fixedly connected with mounting bottom blocks 4, and the mounting bottom blocks 4 are fixed to the bottom plate 1 by screws for easy fixation. In order to improve the connection relationship between the side panel 2 and the mounting side block 3, the side panel 2 and the mounting side block 3 are integrally formed.

[0028] As an implementation method in this embodiment, Figure 5 As shown, a mounting groove 12 is provided on the side of the side panel 2 away from the mounting side block 3, and a sealing gasket 13 is provided between the mounting groove 12 and the mounting side block 3 provided on the adjacent side panel 2. Screws penetrate the mounting side block 3, the sealing gasket 13 and the mounting groove 12 in sequence, so that the sealing gasket 13 is installed between two adjacent side panels 2 to improve the sealing effect between the side panels 2. The mounting groove 12 is in a convex shape to improve the fit between the sealing gasket 13 and the mounting groove 12 and reduce the offset.

[0029] The working principle of the utility model is as follows: when in use, the side panels 2 are assembled to the sides of the bottom plate 1 in sequence, and the mounting bottom block 4 is fixed to the bottom plate 1 by screws. The side panels 2 drive the extrusion block 10 to squeeze the airbag 7. After the airbag 7 is compressed, it drives the convex strip 8 to inflate. The convex strip 8 squeezes the side wall of the arc groove 11, so that the graphite sealing strip 9 slides relatively due to the compression of the arc groove 11, and the graphite sealing strip 9 is further pressed against the gap between the inner frame 5 and the side panel 2, thereby improving the sealing effect and reducing the outflow of liquid from the gap.

[0030] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
