As a new building material with strong decorative effects, rock slabs have many applications in high-end interior hard and soft decoration structures. Rock slabs are made of natural stone and inorganic clay through special processes, such as being fired at 1300°C and other conditions through a vacuum extrusion molding process. It has characteristics such as large specifications, diverse colors, high temperature resistance, wear and scratch resistance, acid and alkali resistance, zero formaldehyde, etc. At the same time, it has a high density, and the performance of rock slabs in terms of flexural strength and other aspects is also good, far exceeding that of ceramic tiles. Rock slabs belong to granite, with very hard texture, good moisture resistance and other properties, and there is no rusting, fading and other situations. Rock slabs can well meet the application of furniture customization aesthetics, can be freely combined, and have strong customization. In addition, rock slabs have the characteristics of safety and environmental protection, can be directly in contact with food, and can be 100% recycled, non-toxic and radiation-free.

This rock slab dry-hanging assembly structure adopts a double fixation method, improves the stability of the rock slab after installation, and thus extends the service life. It is also convenient to adjust the overall verticality and horizontality of the rock slab after dry-hanging, is also conducive to installation, has high stability, and the hanging connection method is conducive to disassembly and assembly, thus facilitating maintenance. And this existing technology has the above-mentioned rock slab assembly problems. Summary of the Invention

As the rock slab is further pressed in, the notch moves to the position of the second hook, and the first hook and the second hook are clamped and positioned, further improving the assembly strength. At the initial stage when the rock slab is pressed against the assembly unit, the ball shaft will first be docked with the second guide groove, and they are arranged in a radial or umbrella shape, which can guide the pressing operation of the rock slab to ensure that they move towards each other along their axes. Until the rock slab is completely docked with the assembly unit, the ball shaft abuts against the spherical abutting surface to achieve structural positioning. After being shaped, the elastic member will apply an outward elastic thrust to the quadrilateral structure composed of the outer rod part, the linkage rod, and the linkage block, making the clamping of the two hooks stronger and more stable, and the fitting positioning of the ball shaft and the spherical abutting surface is sufficient, improving the assembly strength and assembly stability of the rock slab and preventing it from loosening and falling off.

[0057] A plurality of mounting seats 8, which are arranged radially on the back surface of the rock slab 3, and the outer end of the outer rod 62 is docked with the mounting seat 8.

[0058] The slab assembly structure of the present invention realizes the basic support for the slab through the docking of the central positioning seat and the connecting seat and the docking of the two positioning enclosures. On this basis, several groups of rod assemblies arranged in an umbrella shape are used to make multi-point abutment and support on the back of the slab, so that the back tension or support force received after installation is more uniform, the force on the slab surface is balanced, the load on the slab itself and the installed structure after installation is reduced, the assembly stability and structural strength of the structure are improved, and the rod assemblies are arranged in an umbrella shape, having good impact buffering and seismic resistance. After the above structures are docked, the linkage block is radially pushed outwards and docked and positioned with the two positioning enclosures, further improving the firmness of the slab assembly, and the assembly operation is simple, so as to facilitate the rapid assembly of large-format and multiple slabs.

[0059] The central positioning seat 1 is a sleeve structure, and a clamping groove 11 is arranged on its inner wall. The connecting seat 4 is inserted into the central positioning seat 1 and is clamped and positioned with the clamping groove 11 through the clamping block 41 on its surface. The positioning of the slab 3 at the center of the wall 100 is mainly realized by the insertion of the central positioning seat 1 and the connecting seat 4 and the clamping of the clamping groove 11 and the clamping block 41, ensuring the assembly convenience, structural strength and stability.

[0060] The second positioning enclosure 5 is sleeved on the first positioning enclosure 2. The docking of the slab 3 at the edge of the wall 100 is realized by the sleeving of the two positioning enclosures, the close fitting of the opposite sides, and the cooperation of the linkage block 7 with the two for docking, thereby realizing flexible and multiple structural positioning and improving the assembly strength.

[0061] A slot 622 is arranged at the inner end of the outer rod 62. The inner rod 61 is inserted into the slot 622, and an elastic member 623 in the slot 622 exerts an elastic force on the inner rod 61 and the outer rod 62 to move away from each other.

[0062] The assembly process of an assembly design structure of a large-format slab with balanced force in this embodiment includes: before the assembly of the slab 3, several assembly units are arranged on the wall 100, that is, several groups of central positioning seats 1 and first positioning enclosures 2 are positioned thereon; then, the linkage block 7 is arranged and the rod assembly 6 is hinged with the central positioning seat 1 and the linkage block 7; the connecting seat 4, the second positioning enclosure 5 and the mounting seat 8 are arranged on the back of the slab 3; during assembly, a single slab 3 is aligned and pushed towards a single assembly unit, the connecting seat 4 is inserted into the central positioning seat 1 and the clamping is completed. At the same time, the second positioning enclosure 5 is sleeved outside the first positioning enclosure 2. During this period, the outer rod 62 is docked with the mounting seat 8, and as the slab 3 is further pressed in, the inner rod 61 retracts into the outer rod 62, and the two gradually move into the first positioning enclosure 2, and the linkage rod 63 is pressed to push the linkage block 7 to move outwards, so that it is docked and positioned with the two positioning enclosures.

This embodiment is not shown in the drawings and is supplemented here. Under this structural design, after the inner wall of the positioning seat 1 is unfolded along its longitudinal section, the card slots 11 are arranged in a matrix on its surface. Considering that the clamping method may cause structural looseness and thus the risk of the rock slab falling off, therefore, a plurality of card slots 11 are axially arranged along the inner wall of the positioning seat 1, so that after the clamping block 41 disengages from the card slot 11 inside the positioning seat 1, it will be clamped again in another card slot 11 outside. At this time, the rock slab 3 at this place will protrude from other rock slabs 3, reminding the user of the risk of the rock slab 3 falling off, so as to ensure timely structural adjustment and improve the safety of use.

[0065] Embodiment Three:

[0066] Please refer to Figure 1-3 , 5. On the basis of the first embodiment above, preferably, a second hook 71 is arranged on the outer side of the linkage block 7.

The linkage block 7 is slidably arranged in the gap between the two guiding plates 72, and a convex platform 73 extends outward from its side surface. The convex platform 73 is slidably arranged in the first guiding groove 74 inside the guiding plate 72.

[0067] The assembly process of a large-panel rock slab assembly design structure with balanced force in this embodiment includes: the linkage rod 63 is pressed to push the linkage block 7 to move outward, the linkage plate 7 slides along the guiding plate 72 and makes the second hook 71 expose from the first positioning enclosure 2. As the rock slab 3 is further pressed in, the notch 51 moves to the position of the second hook 71, and makes the first hook 52 and the second hook 71 be clamped and positioned, further improving the assembly strength. After shaping, the elastic member 623 will apply an outward elastic thrust to the quadrilateral structure composed of the outer rod 62 locally, the linkage rod 63 and the linkage block 7, making the clamping of the two hooks more firm and stable, and further improving the assembly strength and assembly stability of the rock slab 3, and avoiding its loosening and falling off.

The second guide groove 81 is a cylindrical guide groove, and its diameter is larger than the width of the third guide groove 82. A spherical abutting surface 83 corresponding to the surface of the ball shaft 64 is provided at the outer end of the second guide groove 81.

[0070] The assembly process of a large-sheet-width rock slab assembly design structure with balanced force in this embodiment includes: at the initial stage when the rock slab 3 is pressed against the assembly unit, the ball shaft 64 will first be docked with the second guide groove 81, and the two are arranged radially or in an umbrella shape, which can guide the pressing operation of the rock slab 3 to ensure that the two move towards each other along their axes. Until after the rock slab 3 is docked with the assembly unit, the ball shaft 64 abuts against the spherical abutting surface 83 to achieve structural positioning. After shaping, the elastic member 623 will apply an outward elastic thrust to the quadrilateral structure composed of the outer rod 62 locally, the linkage rod 63, and the linkage block 7, so that the fitting and positioning of the ball shaft 64 and the spherical abutting surface 83 are sufficient, thereby improving the assembly strength and assembly stability of the rock slab 3 and preventing it from loosening and falling off.

[0071] To sum up, due to the adoption of the above technical solutions, a large-sheet-width rock slab assembly design structure with balanced force in this embodiment has the following beneficial effects compared with the prior art:

[0072] 1.

[0074] 3. The linkage rod is pressed to push the linkage block to move outward. The linkage plate slides along the guide plate, causing the second hook to expose from the first positioning enclosure. As the rock slab is further pressed in, the notch moves to the position of the second hook, and the first hook and the second hook are engaged and positioned, further improving the assembly strength. In the initial stage when the rock slab presses against the assembly unit, the ball shaft will first be docked with the second guide groove, and they are arranged in a radial or umbrella shape, which can guide the pressing operation of the rock slab to ensure that they move towards each other along their axial directions.
