Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] like Figures 1-4 As shown, this utility model discloses a prefabricated wall structure, including a wall 1 formed by splicing multiple wall bricks 2 in a row. Two adjacent wall bricks 2 are connected by a first connecting structure 3, and two adjacent wall bricks 2 are connected by a second connecting structure 4. The wall 1 is formed by splicing multiple wall bricks 2 in a 3×3 row, that is, the entire wall 1 is composed of 9 wall bricks 2 arranged in a row and column alignment, and each wall brick 2 is a standard cubic structure.

[0021] The first connecting structure 3 includes a sleeve 5 disposed on the lower surface of the upper wall tile 2. A first spring 6 is disposed inside the sleeve 5. A movable block 7, coaxial with the sleeve 5, is disposed at the lower end of the first spring 6. A rubber block 8 is coaxially disposed at the bottom of the movable block 7. A first mounting hole 9, cooperating with the rubber block 8, is disposed on the upper surface of the lower wall tile 2. The sleeve 5 is fixedly installed at the center of the lower surface of the upper wall tile 2 using expansion screws. The sleeve 5 is a cylindrical metal part, and its axis coincides with the vertical center line of the wall tile 2. The bottom of the sleeve 5 has a threaded hole that matches the bolt, ensuring a secure installation. The first spring 6, a helical compression spring with a wire diameter of 3mm and a free length of 40mm, is coaxially disposed inside the sleeve 5. The upper end of the first spring 6 is fixed to the inner top surface of the sleeve 5 by welding, and the lower end is connected to the top of the movable block 7 by welding. The movable block 7 is a cylindrical metal part with a diameter slightly smaller than the inner diameter of the sleeve 5, ensuring that it can slide freely axially within the sleeve 5. A rubber block 8 is coaxially bonded to the bottom of the movable block 7. The rubber block 8 is cylindrical.

[0022] The second connecting structure 4 includes a movable hole 10 on the right surface of the left wall brick 2, a second spring 11 inside the movable hole 10, and an insert block 12 at the end of the second spring 11. A socket 13, which mates with the insert block 12, is provided on the left surface of the right wall brick 2. The second spring 11 is welded to the insert block 12, and the second spring 11 can be bolted to the movable hole 10. The second spring 11 is welded to a steel plate, and expansion screws are used to connect the steel plate to the inner wall of the movable hole 10. The socket 13 mates with the insert block 12. During wall assembly, the insert block 12 is first blocked by an iron sheet, positioning it in the movable hole 10. Then, the sleeve 5 and rubber block 8 are inserted into the first mounting hole 9 of the lower wall brick 2. The iron sheet is then removed, allowing the insert block 12 to reset and be inserted into the socket 13, thus connecting the two adjacent wall bricks 2.

[0023] To prevent the movable block 7 from dislodging from the sleeve 5, see [reference needed]. Figure 4 Furthermore, a limiting block 14 is provided at the top of the movable block 7, and a limiting boss 15 is provided at the bottom of the sleeve 5. A limiting block 14 with a diameter smaller than the inner diameter of the sleeve 5 is welded to the top of the movable block 7, and a limiting boss 15 extending inward is provided at the bottom of the sleeve 5. The inner diameter of the limiting boss 15 is smaller than the inner diameter of the limiting block 14 and larger than the outer diameter of the movable block 7.

[0024] To further improve the stability of insert 12, see [link to further details]. Figure 3 An installation cylinder 16 is provided inside the movable hole 10. The second spring 11 is sleeved on the outside of the installation cylinder 16. A connecting rod 17 is provided inside the installation cylinder 16. One end of the connecting rod 17 is slidably connected to the inner wall of the installation cylinder 16, and the other end of the connecting rod 17 is fixedly connected to the insert block 12. The installation cylinder 16 is a stainless steel tube with an outer diameter of 22mm. It is fixed to the inner wall of the movable hole 10 with epoxy resin. The connecting rod 17 is coaxially arranged inside the installation cylinder 16. The connecting rod 17 is a steel rod with a diameter of 8mm. One end of the connecting rod is connected to the inner wall of the installation cylinder 16 through a sliding bearing, and the other end is welded to the tail of the insert block 12. One end of the second spring 11 abuts against the inner wall of the movable hole 10, and the other end abuts against the tail of the insert block 12, pushing the insert block 12 to extend towards the insertion hole 13.

[0025] To ensure a tighter fit between the rubber block 8 and the first mounting hole 9, further refer to... Figure 3 and Figure 4 The outer surface of the rubber block 8 is provided with an annular groove 18, and the inner wall of the first mounting hole 9 is provided with an annular protrusion 19 that matches the annular groove 18. The annular groove 18 and the annular protrusion 19 are interference-fitted. The annular groove 18 has a depth of 2 mm and a width of 3 mm. The inner wall of the first mounting hole 9 is provided with an annular protrusion 19 that matches the annular groove 18, and the protrusion height is 2.5 mm. The interference fit achieves a tight fit between the rubber block 8 and the first mounting hole 9.

[0026] To better achieve the assembly of the plug 12 and the socket 13; further, see Figure 3 The end of the insert 12 is wedge-shaped, and the inner wall of the insertion hole 13 is provided with a guide slope 20 adapted to the wedge-shaped structure. The end of the insert 12 is machined into a wedge-shaped structure with an inclination angle of 30°. The entrance of the insertion hole 13 on the left surface of the right wall brick 2 is provided with a guide slope 20 that matches the wedge-shaped structure and has the same inclination angle. When the insert 12 is inserted into the insertion hole 13, the wedge-shaped end contacts the guide slope 20, automatically guiding the insert 12 to center and reducing assembly deviation.

[0027] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
