Figure 1 As shown, taking the first profile 1 as an example (the second profile 2 and the third profile 3 can refer to Figure 2 , 3 ), a semi-enclosed cavity 26 with an opening facing leftward (ie, away from the plug-in portion 14) is provided on the support portion 15. Figure 4 , 5 As shown in Figures 6 and 7, a sheet metal reinforcing plate 7 is provided at the opening of the semi-enclosed cavity 26 to strengthen the support portion 15. An inner lining plate 5 is installed inside the semi-enclosed cavity 26, and an outer lining plate 6 is installed outside the semi-enclosed cavity 26. At the same time, foamed polyurethane 8 is injected between the inner lining plate 5 and the outer lining plate 6 of the semi-enclosed cavity 26, so that it is used as a single panel. The first profile 1, the second profile 2 and the third profile 3 are located at the end positions of the corresponding panels.

[0029] Preferably, the profile of the sheet metal reinforcement plate 7 is in a "C" shape, and a slot 18 is provided on the bottom inner wall of the semi-enclosed cavity 26, and the slot 18 is used to insert and install the inner lining plate 5, and a protrusion 19 is provided on the top inner wall of the semi-enclosed cavity 26 (the direction of the protrusion 19 is perpendicular to the bottom inner wall of the semi-enclosed cavity 26).

It can well ensure the sealing of the unit, greatly reduce the risk of air leakage, and ensure the performance of the unit during operation.

[0032] like Figure 2 , 7 As shown in FIG. 9 , a V-shaped plug 24 is provided at the outer edge of the closed cavity 27 of the third profile 3, which can be plugged into the V-shaped slot 23 of the second profile 2, so that the second profile 2 and the third profile 3 form an extended panel when plane splicing. Further, when plane splicing, refer to the attached Fig. 9 A slot 25 is formed between the supporting portions 15 of the second profile 2 and the third profile 3, and the slot 25 is used to insert the aluminum profile reinforcement plate 9. The left end of the aluminum profile reinforcement plate 9 is fixed to the supporting portion 15 of the second profile 2 by screws 10, and the right end of the aluminum profile reinforcement plate 9 is fixed to the supporting portion 15 of the third profile 3 by screws 10, thereby connecting and fixing the second profile 2 and the third profile 3.

[0033] The working process of this utility model:

[0034] The profiles provided by the utility model can be divided into two splicing methods: single unit splicing (such as Fig.10 As shown), several units are spliced ​​together (as shown Fig.11 As shown in the figure, the splicing of two units is taken as an example). The second profile 2 is provided with a rivet nut 4, and the first profile 1 has a corresponding hole for locking the bolt 11.

[0035] Reference Fig.10 A single unit is spliced ​​using only the first profile 1 and the second profile 2. After the two profiles are formed, they are connected into a unit in a matching combination. That is, each edge of the unit box is assembled and connected into a right-angle structure by the first profile 1 and the second profile 2, and a single panel is arranged on each surface of the box.

[0036] Reference Fig.11The unit with multiple boxes is assembled using the first profile 1, the second profile 2 and the third profile 3, wherein the single box is still assembled according to Fig.10 The third profile 3 is used to cooperate with the second profile 2 at the connection of the box body to form a Fig. 9 Connect as shown.

[0037] Panel forming steps:

[0038] 1. Install the rivet nut 4 on the corresponding hole (i.e., the rivet nut hole 20) on the second profile 2;

[0039] 2. The interior of the three profiles are all supported by sheet metal reinforcement plates 7;

[0040] 3. Before putting on the inner lining plate 5 and the outer lining plate 6, connect them with elastic sealing members 13 around the circumference, and then fix them with tooling;

[0041] 4. Inject polyurethane 8 into the tooling to fill the interior (i.e., between the inner lining plate 5 and the outer lining plate 6 of each semi-enclosed cavity 26).

[0042] Panel to panel installation steps:

[0043] 1. After forming, the panel, such as Figure 7 , 10 As shown, it is installed into a box;

[0044] 2. At the corner joint, bolts 11 are passed through the through holes on the first profile 1 (plug-in portion 14) to be locked onto the rivet nuts 4 of the second profile 2, and decorative caps 12 are placed on the outside of the first profile 1. Figure 7 , 8 As shown;

[0045] 3. At the plane joint, fasten the second profile 2 and the third profile 3 to each other, insert the aluminum profile reinforcement plate 9 into the slot 25 formed by the second profile 2 and the third profile 3 through the screws 10, so that the second profile 2 and the third profile 3 are connected and fixed. Figure 7 , 9 shown.

[0046] Since the second profile adopts an anti-slip design, the rivet nut is fixed in its position without sliding or shifting. At the same time, the bolt is connected through the inside of the first profile, so that there is no screw head on the outer surface of each profile, and the appearance is simple and beautiful. The connection structure between the panels is complex and intertwined, which can well ensure the sealing of the unit, greatly reduce the risk of air leakage, and ensure the performance of the unit during operation. The interior of the frameless air-conditioning box profile panel adopts polyurethane foam and new material joints. Each panel and the sheet metal contact surface have elastic seals, which well ensure the temperature and humidity inside the air-conditioning box. Whether it is cooling or heating, the entire air-conditioning box is insulated to reduce the impact of cold bridges and prevent condensation and rust, which is beneficial to the temperature operation of the entire air-conditioning unit, reduce the energy consumption of the unit, and extend the service life.

[0047] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and the concept of the utility model should fall within the protection scope of the claims attached to the utility model.
