[0024] Figure 2A yes Figure 1 2 is a schematic diagram of a cross section (i.e., a cross section perpendicular to its length direction) of a connecting structure 102, wherein only the inner side beam component, the outer side beam component, and the side beam connecting component of the connecting structure 102 are shown, and other components of the connecting structure 102 are not shown. Since the structural features of the connecting structure 102 of the present invention can be more clearly shown in its cross section, the structural features of the connecting structure 102 are introduced in conjunction with the cross section shown in FIG.

[0026] The inner side beam component 206 is generally in the shape of a rectangular parallelepiped, and its interior is hollow. The inner side beam component 206 can be made of, for example, an aluminum profile. The inner side beam component 206 includes a first inner side beam side wall 209, a second inner side beam side wall 210, a third inner side beam side wall 211, and a fourth inner side beam side wall 212 connected in sequence.

Although such a plug-in structure is shown, it can be understood that in other embodiments, the first outer side beam portion 213 and the second outer side beam portion 214 can also be connected to the inner side beam component 206 by other methods using the first side beam connecting component 208 and the second side beam connecting component 208.

[0030] In one embodiment, the inner side beam component 206 and the outer side beam component 207 are made of metal, and the side beam connecting component 208 is made of a heat insulating material (such as fiberglass, asbestos).

[0031] Figure 2B Too Figure 1 FIG. 1 is a schematic cross-sectional view of the connection structure 102 in FIG. 1 , which shows all components of the connection structure 102. Figure 2B As shown, the connection structure 102 further includes a first outer sealing sheet metal 220 and a second outer sealing sheet metal 226 , a first inner sealing sheet metal 221 and a second inner sealing sheet metal 228 , sealing strips 219 , 227 , and fasteners 229 , 230 .

Of course, the first external sealing sheet metal 220 and the second external sealing sheet metal 226 can also have other structures besides the long "L" shape.

[0033] The first internal sealing sheet metal 221 and the second internal sealing sheet metal 228 are respectively substantially long C-shaped, and have a long side 235 and short sides 236 and 237 extending substantially perpendicularly from both ends of the long side 235, wherein one of the short sides 237 also has an extension portion 241 substantially perpendicular thereto, and the extension portion 241 is substantially parallel to the long side 235. Of course, the first internal sealing sheet metal 221 and the second internal sealing sheet metal 228 may also have other structures besides the long C-shape.

[0034] Figure 3A is used Figure 2B A partial cross-sectional view of adjacent panels 101 of an air conditioning box body with a connection structure 102 is shown. Figure 3A As shown, the panel 101 of the air conditioning box 100 includes an outer surface 201 and an inner surface 202 arranged opposite to each other, and a circumferential side portion 203 connecting the inner surface 202 and the outer surface 201, the circumferential side portion 203 includes an indentation 222 close to the inner surface 202 and a protrusion 223 close to the outer surface 201, and the indentations 222 of adjacent panels 101 together form a receiving portion 204. The protrusion 223 is open and sealed by a heat insulation strip 242. The heat insulation strip 242 is made of PVC, for example. The heat insulation strip 242 is generally "L"-shaped, and has a transverse extension portion 239 and a longitudinal extension portion 240, the transverse extension portion 239 extends generally parallel to the inner surface 202 and the outer surface 201, and the longitudinal extension portion 240 extends generally perpendicular to the inner surface 202 and the outer surface 201. The free ends of the transverse extension portion 239 and the longitudinal extension portion 240 are both provided with openings for receiving the sheet metal portion of the panel 101 , thereby sealing the protruding portion 223 of the panel 101 through the thermal insulation strip 242 .

[0035] Figure 3B yes Figure 2B The connection structure 102 shown is Figure 3A The panel 101 of the air conditioner box is shown as a schematic diagram when it is assembled together. Figure 3BAs shown, the inner side beam component 206 forms a matching portion 205, and the matching portion 205 is accommodated in the receiving portion 204 formed by the indentation 222 of the adjacent panel 101, thereby partially accommodating the inner side beam component 206 in the receiving portion 204. As can be seen from the figure, the first outer side beam surface 224 and the second outer side beam surface 225 of the outer side beam component 207 are configured to be substantially flush with the outer surface 201 of the adjacent panel 101, so that the panel and the connecting structure 102 appear to be flat. Therefore, the lateral extensions 239 of the two thermal insulation strips 242 face the third inner side beam side wall 211 and the fourth inner side beam side wall 212 of the inner side beam component 206 respectively. The sealing strips 219 and 227 are arranged between the lateral extensions 239 of the two thermal insulation strips 242 and the third inner side beam side wall 211 and the fourth inner side beam side wall 212 of the inner side beam component 206, and the sealing strips can be, for example, rubber and plastic sealing strips. Fasteners 229 / 230 (such as self-tapping screws) may be passed through the lateral extension 239 of the thermal insulation strip 242 , the sealing strips 219 , 227 , and the third inner side beam side wall 211 and the fourth inner side beam side wall 212 to fasten them together.

[0036] As shown in the figure, the first inner sealing sheet metal 221 and the second inner sealing sheet metal 228 are respectively located between the first inner side beam side wall 209 and the second inner side beam side wall 210 of the inner side beam component 206 and the indentation 222 of the circumferential side portion 203 of the two panels 101. The long sides 235 (see Figure 2B ) are respectively attached to the first inner side beam side wall 209 and the second inner side beam side wall 210, and the long sides 235 of the first inner sealing sheet metal 221 and the second inner sealing sheet metal 228 are fastened together with the first inner side beam side wall 209 and the second inner side beam side wall 210 of the inner side beam component 206 by self-tapping screws. The extensions 241 of the first inner sealing sheet metal 221 and the second inner sealing sheet metal 228 (see Figure 2B ) are respectively attached to the indented portions 222 of the two panels 101. The first external sealing sheet metal 220 and the second external sealing sheet metal 226 are respectively arranged between the first external edge beam portion 213 and the second external edge beam portion 214 and the protruding portions 223 of the circumferential side portions 203 of the two adjacent panels 101. The long sides 232 (see Figure 2B ) are respectively attached to the first outer side beam portion 213 and the second outer side beam portion 214, and the long sides 232 of the first external sealing sheet metal 220 and the second external sealing sheet metal 226 are respectively fastened together with the first external side beam portion 213 and the second external side beam portion 214 by self-tapping screws, and the extension portions 234 of the first external sealing sheet metal 220 and the second external sealing sheet metal 226 (see Figure 2B ) are respectively attached to the protrusions 223 of the two panels 101.

[0037] Therefore, the connection structure 102 not only connects two adjacent panels 101 together, but also provides a sealing structure, which is composed of sealing strips 219, 227, a first internal sealing sheet metal 221, a second internal sealing sheet metal 228 and a first external sealing sheet metal 220, and a second external sealing sheet metal 226.
