[0028] It should be noted that: unless otherwise defined, the technical terms or scientific terms used in this article should be understood by people with ordinary skills in the field to which the utility model belongs. The words "one", "an" or "the" and the like used in the patent application specification and claims of this utility model do not express quantitative restrictions, but indicate the existence of at least one; the "first", "second" and "third" used in this article should not be regarded as restrictions on the order of components, but are only used to distinguish different components; "include" or "comprise" and other similar words indicate that the elements or objects appearing before "include" or "comprise" include the elements or objects listed after "include" or "comprise" and their equivalents, but do not exclude other elements or objects with the same function.

[0029] In order to more clearly describe the specific structural composition of the series bottom frame, Figure 1-3 Describe this embodiment:

[0030] like Figure 1 or Figure 2 As shown, the series bottom frame is formed by at least two frames for carrying shelf boards connected in series in the longitudinal direction;

[0031] Each frame includes a longitudinal beam 1 and a transverse beam 2, wherein there are at least two longitudinal beams 1 arranged at intervals, and at least two transverse beams 2 are distributed on the upper surface of the longitudinal beam 1 at intervals along the length direction of the longitudinal beam 1;

[0032] Among them, the longitudinal beam 1 is a hollow rod with open ends;

[0033] A plug-in connector 5 is disposed on the open inner side of one end of the longitudinal beam 1 of each frame, and the other end of the longitudinal beam 1 of each frame is left vacant to form a slot 101;

[0034] When two adjacent frames are connected in series in the longitudinal direction, the connector 5 of one frame extends into the slot 101 of the adjacent frame. The frame supports the shelf board, reduces the instability factor of the shelf board directly on the roller table, and sets a detachable connector 5 on the frame, which is conducive to the alignment of adjacent frames or shelf boards, avoids deviation and gap separation, and ensures the quality of the final firing.

[0035] Specifically, during use, the frames are connected in series and placed on the side plates of the mold when entering the furnace, and the shelf plates are pressed on the frames composed of the longitudinal beams 1 and the cross beams 2. After leaving the furnace, the slots 101 and the connectors 5 of the adjacent frames are disengaged.

[0036] One end of the connector 5 is detachably connected to the longitudinal beam 1 through a fastener 4; a pin hole 3 is provided at the intersection node of the longitudinal beam 1 and the cross beam 2, and the fastener 4 passes through the pin hole 3 to connect the longitudinal beam 1 and the cross beam 2;

[0037] In this embodiment, the connector 5 is as follows Figure 3 As shown, a limiting hole 501 is provided at one end close to the fastener 4, and the fastener 4 extends into the hollow of the longitudinal beam 1 and is inserted into the limiting hole 501. The fastener 4 is a connecting structure of the frame on the one hand, and is also a connecting structure of the plug-in connector 5 on the other hand. Connecting the plug-in connector 5 with the fastener 4 of the frame facilitates the installation and removal of the plug-in connector 5, and does not require additional welding or fixing of the plug-in connector 5. At the same time, it also makes the various components constituting the series frame simple and easy to process.

[0038] The end of the connector 5 extending to the adjacent frame is provided with a cone 502. When two adjacent frames are connected in series in the longitudinal direction, the structure of the cone 502 makes it easy for the connector 5 of one frame to enter the slot 101 of the adjacent frame, making it easy to install. The sizes of the two ends of the cone are different, and the end away from the limiting hole 501 is smaller.

[0039] In order to ensure the stability of the connection between the plug-in component 5 and the slot 101 on the longitudinal beam 1 after plugging, the cross-sectional shape of the plug-in component 5 is designed to be the same as the cross-sectional shape of the hollow cavity of the longitudinal beam 1, and the two are clearance-matched.

[0040] Specifically, the fastener 4 is a pin, a bolt, etc.

[0041] During use, when two adjacent frames are connected in series in the longitudinal direction, the ends of the longitudinal beams 1 of the two frames are abutted, and the connectors 5 are completely located in the hollow cavities of the longitudinal beams 1 of the two frames.

[0042] The parts not described in detail in this embodiment are prior art.

[0043] It should be noted that although the utility model is described through the above embodiments, the utility model can also have other multiple embodiments. Without departing from the spirit and scope of the utility model, it is obvious that those skilled in the art can make various corresponding changes and deformations to the utility model, but these changes and deformations should all fall within the scope of protection of the attached claims of the utility model and their equivalents.
