[0035] As attached Figure 1 - Appendix Figure 4 As shown, this utility model provides a bearing plate assembly, including a bearing plate 1 and a support assembly. The support assembly includes a column 2, a positioning pin 3 and a locking component 4.

[0036] One or more (two or more) support plates 1 are provided. When only one support plate 1 is provided, the firing plate assembly is a single-layer load-bearing structure. When multiple support plates 1 are provided, the firing plate assembly is a multi-layer load-bearing structure, which can greatly improve the load-bearing capacity. When only one support plate 1 is provided, the support plate 1 is placed on top of the column 2. At this time, the column 2 is used to support the firing plate assembly in the placement position. When multiple support plates 1 are provided, two adjacent support plates 1 are arranged in parallel with each other through the column 2, that is, two adjacent support plates 1 are supported by each other through the column 2. The column 2 is provided below the bottom support plate 1. The bottom support plate 2 is used to support the firing plate assembly in the placement position. At this time, except for the top support plate 1 which only has a column 2 below it, other support plates 1 are provided above and below.

[0037] A through hole 11 is provided on the surface of the support plate 1. A positioning pin 3 is fitted into the through hole 11. A locking member 4 is simultaneously fitted into the positioning pin 3 and the column 2 to limit the positioning pin 3 to the column 2. This achieves the goal of limiting the support plate 1 to the column 2 by the positioning pin 3, and limiting the positioning pin 3 to the column 2 by the locking member 4. This configuration, through the positioning interlock of the locking member 4, secures the support component to the support plate 1, providing convenient assembly and disassembly, and stable and reliable installation.

[0038] It should be noted that when there are columns 2 above and below the bearing plate 1, the lower side of the positioning pin 3 is engaged with the lower column 2 through the engaging part 4, and the upper side is engaged with the upper column 2 through the engaging part 4 or the body of the positioning pin 3, thereby providing a limit on the upper column 2 of the bearing plate 1.

[0039] This invention utilizes a modular design for the firing plate assembly, comprising a support plate 1, columns 2, positioning pins 3, and engaging parts 4. This facilitates independent production and processing of each component, reducing unit manufacturing costs. Furthermore, it allows for easy disassembly and replacement of any damaged or unused component, improving the maintainability of the firing plate assembly. Additionally, the modular design allows for selection of the number of layers in the support plate 1 as needed, offering strong adaptability.

[0040] The positioning pin 3 and the locking piece 4 can conveniently and quickly fix the bearing plate 1 to the column 2 stably, and can also fix and limit the column 2 above and below the bearing plate 1, thereby improving the overall support effect.

[0041] In addition, the structure of the bearing plate 1 in this utility model can be polygonal, circular or other irregular structure, which can be selected according to actual needs. The number of support components under each bearing plate 1 can also be selected as needed, as long as the support components can stably support the bearing plate 1.

[0042] In this utility model, the locking component 4 is provided in two embodiments, as shown in the attached drawing. Figure 1 - Appendix Figure 2 In one embodiment, the top and bottom of the column 2 are provided with fitting holes 21;

[0043] The engaging component 4 includes a plate 41, with an engaging protrusion 411 protruding from the lower part of the plate 41 to engage with the engaging hole 21 above the column 2, and an engaging groove Ⅰ 412 recessed from the upper part of the plate 41 to engage with the bottom of the positioning pin 3.

[0044] The plate 41 is positioned between the top of the column 2 and the bottom of the bearing plate 1.

[0045] During installation, the plate 41 is placed on top of the column 2, and the fitting protrusion 411 engages with the fitting hole 21 on the top of the column 2 to limit the movement of the plate 41 along the upper plane of the column 2. Then, the support plate 1 is placed on the plate 41. At this time, the through hole 11 and the fitting groove Ⅰ 412 are coaxially arranged. The positioning pin 3 engages with both the fitting groove Ⅰ 412 and the through hole 11, and the upper end of the positioning pin 3 extends out of the through hole 11. When the column 2 is placed above the support plate 1, the fitting hole 21 at the lower end of the column 2 engages with the positioning pin 3 extending out of the through hole 11, thereby fixing and limiting the upper column 2. With this arrangement, the support plate 1 can be fixedly and limitedly connected to one or two columns 2.

[0046] In this embodiment, the outer dimension of the plate 41 is greater than or equal to the outer dimension of the column 2. This arrangement increases the load-bearing area of ​​the bearing plate 1, reduces stress concentration, and thus improves the stability and service life of the bearing plate 1.

[0047] In this embodiment, the snap-fit ​​component 4 is an independent part that can work with the positioning pin 3 to simultaneously position and fix the upper and lower columns 2 of the bearing plate 1, making assembly convenient and quick.

[0048] Reference Appendix Figure 3 - Appendix Figure 4In another embodiment of the engaging component 4, the top and bottom of the column 2 are provided with engaging holes 21;

[0049] The locking component 4 includes a limiting ring I 42;

[0050] The limiting ring I 42 is set in the fitting hole 21 at the top of the column 2, that is, the outer wall of the limiting ring I 42 is engaged with the inner wall of the fitting hole 21 at the top of the column 2, and the limiting ring I 42 is provided with a fitting groove II 421 that fits into the bottom of the positioning pin 3.

[0051] The bottom of the positioning pin 3 engages with the fitting groove II 421, and the pin body mates with the through hole 11. This allows the limiting ring I 42 to limit the positioning pin 3, and the positioning pin 3 to limit the bearing plate 1. The fitting groove II 421 can be either a blind hole or a through hole. When it is set as a blind hole, it can limit the vertical position of the positioning pin 3.

[0052] In this embodiment, the locking component 4 also includes a limiting ring II 43, which is provided with a through groove 431 and is disposed in the bottom fitting hole 21 of the column 2 above the bearing plate 1.

[0053] The upper end of the positioning pin 3, which is engaged with the upper limit ring I 42 of the column 2 below the support plate 1, extends upward through the through hole 11, and the through groove 431 of the limiting ring II 43 inside the column 2 above the support plate 1 is fitted with the outer wall of the positioning pin 3. In this way, the limiting ring II 43 realizes the limiting and fixing of the positioning pin 3 and the column 2 above the support plate 1.

[0054] When the fitting groove II421 is a through hole, the structures of the limiting ring I42 and the limiting ring II43 are the same, which further reduces the production cost.

[0055] In embodiments without a limiting ring Ⅱ43, the positioning pin 3 can be a stepped shaft structure with a larger upper section and a smaller lower section. In this case, the smaller lower section engages with the fitting groove Ⅱ421, and the larger upper section engages with the bottom fitting hole 21 of the column 2 above the bearing plate 1.

[0056] In this embodiment, the two columns 2 above and below the bearing plate 1 are fixed and positioned by the combination of limiting ring I 42 and limiting ring II 43, and with the help of a positioning pin 3. The two bearing plates 1 are only separated by columns 2, that is, the distance between the two bearing plates 1 is equal to the height of the columns 2, which can ensure a compact structure.

[0057] In one embodiment, the positioning pin 3 is a tubular structure with a hollow interior and open ends. This design reduces the amount of material used for the positioning pin 3, thereby reducing overall material consumption and weight, and saving costs. It also reduces heat absorption, thus saving heat during sintering.

[0058] In one embodiment, the top outer side of the positioning pin 3 is chamfered. This design facilitates the mounting of the column 2 above the support plate 1 onto the positioning pin 3, or the mounting of the limiting ring II 43 onto the positioning pin 3, simplifying the assembly process.

[0059] In one embodiment, the column 2 is a hollow tubular structure with openings at both ends. In this case, the openings at both ends of the column 2 are two fitting holes 21. This design reduces the material used in the column 2, lowering overall material consumption and weight, thus saving costs. Furthermore, it reduces heat absorption, thereby saving heat during sintering.

[0060] In one embodiment, several sets of support components are disposed beneath each support plate 1. This arrangement can improve the support effect of the support components. Preferably, the number of support components beneath each support plate 1 is consistent and corresponds one-to-one, thereby ensuring that the load-bearing area and load-bearing capacity of each support plate 1 are consistent.

[0061] In one embodiment, the carrier plate 1 and the support assembly are made of silicon carbide. This allows the carrier plate assembly to have high thermal conductivity, reducing the heat consumption during the sintering of daily-use ceramics.

[0062] The above description is merely an embodiment and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations, modifications, or alterations to the technical solution of this utility model without departing from its scope. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model, without departing from its scope, should fall within the protection scope of this utility model.
