[0002] Stainless steel sheets are widely used in building decoration, furniture manufacturing, industrial equipment, and kitchenware due to their corrosion resistance, high strength, and aesthetic appeal. Currently, most stainless steel sheets on the market are monolithic structures with fixed dimensions at the factory. However, in practical applications, different sizes of sheets are often needed to meet specific requirements. Fixed-size sheets cannot meet these needs, necessitating welding or cutting, resulting in poor flexibility. Furthermore, some existing spliced ​​sheet structures are fixed and cannot be selectively used, and the connection points lack sufficient strength, easily loosening, detaching, or even breaking under load or vibration, leading to poor splicing results. Therefore, there is an urgent need for a stainless steel sheet structure that can flexibly adjust the area according to actual needs, and offers strong splicing, good integrity, and aesthetics.

[0020] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0021] Example:

[0022] The accompanying drawings illustrate a specific embodiment of an expandable and modular stainless steel sheet according to this utility model. It is mainly composed of multiple basic sheet unit A units with identical structures spliced ​​together. The structure of the basic sheet unit A is as follows: Figure 1 As shown, each basic board unit A includes a board body 1. The longitudinal length of the board body 1 is a fixed processing size according to the usage scenario. On the transverse width of the board body 1, the left and right sides of the board body 1 are respectively provided with a snap-fit ​​tenon 3 and a snap-fit ​​groove 7. By using the cooperation of the snap-fit ​​tenon 3 and the snap-fit ​​groove 7, they can be interlocked to prevent them from separating laterally.

[0023] Specifically, in combination Figure 2 A left cavity 1a is provided on the left side of the plate 1. The left side and bottom of the left cavity 1a are connected to the outside. The height of the left cavity 1a is less than the thickness of the plate 1. A left rotating shaft 11 is rotatably installed in the left cavity 1a. The length of the left rotating shaft 11 extends along the length direction of the plate 1. The left rotating shaft 11 is connected to a left rotating plate 2, which can rotate synchronously with the left rotating shaft 11. The left rotating plate 2 is provided with several equally spaced locking tenons 3. The cross-section of the locking tenon 3 is trapezoidal, and the short side of the locking tenon 3 is connected to the left rotating plate 2. Each locking tenon 3 is provided with a locking hole 4. The structure of the locking hole 4 is as described above. Figure 3 As shown, the locking hole 4 includes an upper expansion section 4a and a lower contraction section 4b that are connected vertically. The inner diameter of the upper expansion section 4a is larger than the inner diameter of the lower contraction section 4b.

[0024] When the snap-fit ​​tenon 3 is closed, both the snap-fit ​​tenon 3 and the left-turning plate 2 are housed within the left cavity 1a, as follows: Figure 4 As shown. When needed, by pushing the locking tenon 3 outward from the bottom of the left cavity 1a, the left rotating plate 2 and the left rotating shaft 11 can be rotated synchronously. After the locking tenon 3 is fully rotated out, the short side of the locking tenon 3 fits against the left side of the plate 1, and the upper surface of the locking tenon 3 is flush with the upper surface of the plate 1.

[0025] Combined Figure 2 The right side of the plate 1 has a right cavity 1b, which is connected to the outside on the right side and bottom. The height of the right cavity 1b is less than the thickness of the plate 1. A right rotating shaft 12 is rotatably installed inside the right cavity 1b. The length of the right rotating shaft 12 extends along the length of the plate 1. The right rotating shaft 12 is connected to a right rotating plate 5, which can rotate synchronously with the right rotating shaft 12. The right rotating plate 5 is connected to a right extension plate 6, which is the same length as the plate 1. The right extension plate 6 has several locking grooves 7 that correspond one-to-one with each locking tenon 3. The shape and size of the locking grooves 7 are adapted to the locking tenons 3. Each locking groove 7 has an internal threaded hole 8. When the locking tenon 3 and the locking groove 7 are vertically aligned, the center of the locking hole 4 and the center of the internal threaded hole 8 are offset in the left-right direction. The center of the locking hole 4 is located to the right of the center of the internal threaded hole 8. This facilitates a tighter fit between the two plates 1 when locking them.

[0026] When the snap-fit ​​groove 7 is closed, both the right extension plate 6 and the right rotating plate 5 are housed within the right cavity 1b, as follows: Figure 4 As shown. When needed, the right extension plate 6 is pushed outward from the bottom of the right cavity 1b, which can drive the right rotating plate 5 and the right rotating shaft 12 to rotate synchronously. After the right extension plate 6 is fully rotated out, the right extension plate 6 is attached to the right side of the plate body 1, and the upper and lower surfaces of the right extension plate 6 are flush with the upper and lower surfaces of the plate body 1, that is, the height of the right extension plate 6 is the same as the thickness of the plate body 1.

[0027] When two panels 1 are joined together, as follows Figure 5 As shown, the snap-fit ​​groove 7 of the first plate 1 is unscrewed, and the snap-fit ​​tenon 3 of the second plate 1 is unscrewed. Then, each snap-fit ​​tenon 3 is inserted into its corresponding snap-fit ​​groove 7 to achieve mutual interlocking and prevent lateral separation. Then, the locking pins 9 are used for further connection and fixation. Specifically, in conjunction with... Figure 6The locking pin 9 includes a smooth guide portion 901 and a threaded portion 902 located at the center of the bottom of the smooth guide portion 901. When the locking pin 9 is installed, the threaded portion 902 passes through the locking hole 4 and is threadedly connected to the internal threaded hole 8. The smooth guide portion 901 is adapted to be installed within the lower constriction section 4b of the locking hole 4. Figure 7 As shown, each locking hole 4 and internal threaded hole 8 is locked together by a locking pin 9, thereby completing the splicing between the two basic plate units A.

[0028] Each locking hole 4 is also provided with a decorative cap 10 covering the locking pin 9, combined with Figure 6 , Figure 7 The decorative cap 10 is located within the upper expansion section 4a of the locking hole 4. The bottom of the decorative cap 10 has a receiving cavity 10a for receiving a smooth guide portion 901 for receiving the locking pin 9. The decorative cap 10 can directly cover the locking pin 9. The top of the decorative cap 10 also has a slot 10b for easy removal.
