[0002] In today's era, the decoration industry is booming and evolving rapidly. Customers are becoming increasingly demanding regarding surface integrity, and their aesthetic standards are constantly evolving. Consequently, future decorative products are becoming increasingly refined, with customers striving for ultra-thin, high-quality, and flawless decorative spaces.

[0003] Especially in the display case design field for high-end shopping malls and the luxury goods industry, an increasing number of oversized, ultra-thin ceiling lintels and double-faced walls have become a mainstream trend. However, this design trend inevitably presents numerous challenges for production and on-site assembly. The oversized wall panels not only present difficulties in transportation but also make on-site installation very cumbersome. Paint-related surface treatments and on-site cutting and fabrication of various components are generally prohibited within the construction area. Therefore, all components are prefabricated and must be assembled on-site. Furthermore, on-site assembly time is often very tight, placing extremely high demands on assembly efficiency and quality. Large wall panels are typically constructed in sections and then joined on-site, with connectors being a crucial factor in ensuring the desired effect of the wall joints. Summary of the Invention

DETAILED DESCRIPTION

[0032] The present invention will be described in further detail below with reference to the accompanying drawings.

[0033] like Figure 1-8 As shown, the wall splicing invisible connector of the present invention includes an embedded part A1 and an embedded part B2.

[0034] The embedded part A is a long square tube 13, in which one end of three square tube-type clamping columns 11 is vertically fixed to the inner bottom surface of the long square tube 13 opposite to an outer side surface, and the other end passes through the outer side surface. The clamping column 11 passes through the end face of the outer side surface and is sealed, and a locking hole 12 with a trapezoidal cross-section is opened in the part close to the outer side surface. The three clamping columns 11 are arranged in a row along the length direction of the long square tube 13, and the three locking holes 12 are connected to form a channel in the length direction of the long square tube 13.

[0035] The embedded part B includes a rectangular outer box 21 and a lock core.

[0036] The rectangular outer box is a square tube with an end plate 213 sealed at one end and the other end open. The end plate 213 has a bolt hole 212. The bottom and top surfaces of the rectangular outer box 21 have three vertically connected locking holes 211. The three locking holes 211 are arranged in a row along the length of the rectangular outer box 21.

[0037] The lock core includes a rectangular inner box 22 without a cover, and three long holes 221 are opened at the bottom of the rectangular inner box 22. A partition 222 is fixed at one end of the long hole 221 to divide the inner box 22 into three spaces. A wedge-shaped lock tongue 223 is fixed at the lower part of the partition 222. The thick end of the lock tongue 223 is vertically fixed to the partition 222, and the thin end of the lock tongue 223 is suspended in the air, so that the lock tongue 223 is suspended at one end of the long hole 221. There is a gap 225 between the thin end and the other end of the long hole 221 in the longitudinal direction of the rectangular inner box 22. The long hole 221 and the lock tongue 223 are arranged in a row along the longitudinal direction of the rectangular inner box;

[0038] The inner box 22 is located inside the outer box 21, and the latch hole 211 is connected to the gap 225; there are bolt holes 212 and 226 on the side walls of the rectangular outer box 21 and the inner box 23 on the same side, respectively, and a nut 224 is fixed on the wall side at the corresponding position of the inner box bolt hole 226, and there is a distance between the outer box bolt hole 212 and the inner box bolt hole 226.

[0039] The end plate 213 of the outer box 21 and the side wall of the inner box 22 adjacent to the end plate are respectively provided with bolt holes 212 and 226. A nut 224 is fixed on the side wall corresponding to the inner box bolt hole 226. There is a gap between the outer box bolt hole 212 and the inner box bolt hole 226. The bolt 23 passes through the outer box bolt hole 212, the inner box bolt hole 226 and the nut 224 in sequence to fix the outer box 21 and the inner box 22. By turning the bolt 23, the inner box 22 can slide horizontally between the gaps.

[0040] like Figure 9-10 As shown, the clamping column 11 is inserted into the clamping hole and the gap, the bolt 23 is turned, and the inner box 22 is pulled to slide horizontally in the outer box 21. The clamping column 11 slides in the long hole 221, and at the same time, the lock tongue 223 extends into the lock hole 12 and the thick end of the lock tongue, and the connecting piece is in a locked state.

[0041] The connecting piece of the present invention includes an embedded part A and an embedded part B, which are embedded in advance inside the double-faced wall. On site, it is only necessary to align the two side faces of the embedded parts in the two walls to be spliced, insert the clamping column into the clamping hole, turn the bolt, pull the inner box to slide horizontally, get stuck in the long hole and slide from the other end to one end, and at the same time, extend the lock tongue into the lock hole to splice the two walls into one.

[0042] This invisible connector is suitable for connecting various walls and shopping mall lintels (connection section width is 40-150mm and height is 200-4000mm).

[0043] Installation steps

[0044] 1. First, fix embedded part A to the section of one of the panels to be connected. Ensure that it is firmly installed and positioned correctly.

[0045] 2. Next, assemble embedded part B. Push the lock cylinder into the open end of the rectangular outer box, ensuring that all components are installed correctly and fit tightly, and that the holes and gaps are connected and can be inserted into the locking column.

[0046] 3. Then, embed the assembled embedded part B into the section of the other wall to be connected. Note that the embedded depth and position must meet the design requirements.

[0047] 4. Finally, join the two sections of the wall with embedded parts, align the clamping column with the clamping hole, insert it, and tighten the screws on the end plate to ensure a firm connection.
