Description

Technical Field

[0001] This utility model relates to the technical field of kiln furniture for ceramic products, and in particular to a kiln support component for synchronous shrinkage. Background Technology

[0002] Currently, during the firing process of relatively large ceramic blanks, due to the special nature of the process, the blanks will shrink to a certain extent. However, the existing blank support components will not shrink with the blanks. Under the combined action of shrinkage force and friction between the blank and the blank support surface, the blank will deform and tear at the contact surface with the blank support surface, affecting the firing quality of the product. In severe cases, it will lead to the fired blanks becoming waste products. Utility Model Content

[0003] This invention aims to address the shortcomings of existing technologies by providing a synchronously retractable shelf support.

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

[0005] The synchronously retractable shelf support includes a base plate with several limiting grooves on its upper surface. Four circular grooves are located outside each limiting groove on the upper surface of the base plate, corresponding to the four corners of the limiting groove. Several rolling balls are located within the circular grooves. A cover plate is located above each limiting groove, with its bottom supported on the rolling balls. A limiting block is located at the bottom of the cover plate, movably positioned within the corresponding limiting groove. The support also includes several foam positioning blocks, which are engaged with the cover plate for positioning.

[0006] There is a central polygonal hole at the bottom center of the base plate, two round holes on both sides of the central polygonal hole, and a side polygonal hole on the outside of the round holes. There is a connecting groove between the side polygonal hole and the side wall of the base plate.

[0007] A first groove is symmetrically provided on the front and rear sides of the bottom of the base plate. A second groove is provided on both sides of the first groove. A third groove is provided on the outside of the second groove. The first groove, the second groove and the third groove are all connected to the corresponding side of the base plate.

[0008] There are six limiting grooves on the base plate. Four of them are of equal size and are located at the four corners of the upper surface of the base plate. The other two are of equal size and are located on the front and back sides of the middle of the upper surface of the base plate.

[0009] There are six cover plates, four of which are of equal size and located above the limiting grooves at the four corners of the base plate, and the other two are of equal size and distributed above the two middle limiting grooves.

[0010] There are two foam positioning blocks, and each foam positioning block forms a positioning snap-fit ​​with the two middle cover plates and the two side cover plates.

[0011] The longitudinal section of the limiting groove is an isosceles trapezoidal structure that is wider at the top and narrower at the bottom, and the longitudinal section of the limiting block is also an isosceles trapezoidal structure that is wider at the top and narrower at the bottom. The inclination of the side of the limiting block is consistent with the inclination of the inner wall of the limiting groove.

[0012] The beneficial effects of this utility model are as follows: This utility model utilizes the foam positioning block to form a snap-fit ​​with the cover plate, preventing the cover plate from falling off and forming a protective layer. In use, the foam positioning block is removed, the large ceramic blank is placed on the cover plate, and moved into the kiln for firing. During the firing process, the large ceramic blank will shrink, and the cover plate can move with the product shrinkage, thereby playing a role in cooperating with the shrinkage, preventing the product from deforming or tearing, and improving the firing quality of the product.

[0026] The upper surface of the base plate 1 is provided with several limiting grooves 2. Four circular grooves 3 are provided outside each limiting groove 2 on the upper surface of the base plate 1. The four circular grooves 3 are set at the four corners of the limiting groove 2. Several rolling balls 4 are provided in the circular grooves 3. A cover plate 5 is provided above each limiting groove 2. The bottom of the cover plate 5 is supported on the rolling balls 4. A limiting block 6 is provided at the bottom of the cover plate 5. The limiting block 6 is movably set inside the corresponding limiting groove 2. It also includes several foam positioning blocks 7, which are positioned and engaged with the cover plate 5.

[0027] The bottom of the base plate 1 is provided with several grooves. In order to reduce weight, the number and shape of the grooves can be designed according to the actual situation and are not limited to one type.

[0028] For example:

[0029] The bottom of the base plate 1 has a central polygonal hole 8 in the middle, two round holes 9 on both sides of the central polygonal hole 8, a side polygonal hole 10 on the outside of the round holes 9, and a connecting groove 11 between the side polygonal hole 10 and the side wall of the base plate 1.

[0030] A set of first grooves 12 are symmetrically provided on the front and rear sides of the bottom of the base plate 1. Second grooves 13 are provided on both sides of the first grooves 12. A third groove 14 is provided on the outside of the second grooves 13. The first grooves 12, the second grooves 13 and the third grooves 14 are all connected to the corresponding side of the base plate 1.

[0031] There are six limiting grooves 2 on the base plate 1. Four of them are of equal size and are distributed at the four corners of the upper surface of the base plate 1. The other two are of equal size and are distributed on the front and back sides of the middle position of the upper surface of the base plate 1.

[0032] There are six cover plates 5, four of which are of equal size and located above the limiting grooves 2 at the four corners of the base plate 1, and the other two are of equal size and distributed above the two middle limiting grooves 2.

[0033] The dimensions of the base plate 1 are 670×345×25mm; the dimensions of the cover plate 5 are 212.5×165×12mm or 165×165×12mm.

[0034] There are two foam positioning blocks 7, and each foam positioning block 7 forms a positioning engagement with the two middle cover plates 5 and the two side cover plates 5.

[0035] The number of rolling balls 4 in each circular groove 3 is three.

[0036] The longitudinal section of the limiting groove 2 is an isosceles trapezoidal structure that is wider at the top and narrower at the bottom. The longitudinal section of the limiting block 6 is also an isosceles trapezoidal structure that is wider at the top and narrower at the bottom. The inclination of the side of the limiting block 6 is consistent with the inclination of the inner wall of the limiting groove 2.

[0037] The distance between the bottom of the cover plate 5 and the top of the base plate 1 is 3mm, and the distance between the bottom of the limiting block 6 and the bottom of the limiting groove 2 is 3mm.

[0038] When not in use, the foam positioning block 7 and the cover plate 5 are interlocked to prevent the cover plate 5 from falling off, thus providing protection. When in use, the foam positioning block 7 is removed, the large ceramic blank is placed on the cover plate 5, and moved into the kiln for firing. During firing, the large ceramic blank will shrink, and the cover plate 5 can move with the product shrinkage, thereby playing a role in cooperating with the shrinkage, preventing the product from deforming or tearing, and improving the firing quality of the product. The various groove structures set on the bottom plate 1 can improve the uniformity of heat and better meet the uniformity of firing heat, and can also reduce weight.

[0039] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner.
