As shown in fig. 17 to 20, as an embodiment of the present invention, a first groove 101 and a second groove 102 are further disposed above the blocking structure 1301, the first groove 101 and the second groove 102 are respectively located at an outer side of the first reinforcing plate 11 and the second reinforcing plate 12, the inner groove wall of the first groove 101 away from the first reinforcing plate 11 is inclined towards the outer groove wall, and the inner groove wall of the second groove 102 away from the second reinforcing plate 12 is inclined towards the outer groove wall. In the actual connection process, when the second connection inclined surface 511 of a horizontal box plate is in contact with the inner groove wall of the first groove 101 far away from the first reinforcing plate 11 and moves towards the bottom of the groove, the third connection plate 51 moves away from the box body side towards the direction close to the first reinforcing plate 11 and is mutually attached to the outer side of the first reinforcing plate 11; when the second inclined connecting surface 511 of another adjacent horizontal box plate contacts the inner wall of the second groove 102 away from the second reinforcing plate 12 and moves toward the bottom of the groove, the third connecting plate 51 moves away from the box toward the second reinforcing plate 12 and abuts against the outer side of the second reinforcing plate 12. Therefore, in the present invention, the first section 5 can be locked or separated from the first groove 101 and the second groove 102 of the blocking structure 1301 by the second connecting protrusion 524, which is convenient for an operator to detach and install, and the operator can adjust the assembling gap between the first section 5 and the connecting frame 1 according to the locking degree between the second connecting protrusion 524 and the first groove 101 or the second groove 102, and the assembling gap is controllable. For example, when the second connecting protrusion 524 is not properly installed in the first groove 101 or the second groove 102, a splicing gap is formed between the third connecting plate 51 of the first profile 5 and the first reinforcing plate 11 or the second reinforcing plate 12, and conversely, it is ensured that no splicing gap is formed between the first profile 5 and the connecting frame 1, so as to improve the overall sealing performance and the cold bridge breaking effect. Of course, the operator may verify the second connecting protrusion 524 and the first groove 101 or the second groove 102 in a mutually installed and locked state reversely according to the assembly gap between the third connecting plate 51 and the first reinforcing plate 11 or the second reinforcing plate 12.

In other embodiments, the side of the second connecting protrusion 524 away from the box is in the same plane as the side of the third connecting plate 51 away from the box. When the second inclined connecting surface 511 contacts the side of the first protrusion 131 close to the first reinforcing plate 11 during actual installation, the second connecting protrusion 524 may abut against the outer side of the first reinforcing plate 11 close to the first reinforcing plate side, and the third connecting plate 51 may abut against the outer side of the first reinforcing plate 11; similarly, when the second connection inclined surface 511 contacts the side of the second protrusion 132 adjacent to the second reinforcing plate 12, the second connection protrusion 524 adjacent to the second reinforcing plate side may abut against the outer side of the second reinforcing plate 12, and the third connection plate 51 may abut against the outer side of the second reinforcing plate 12. Therefore, in the present embodiment, the first reinforcing plate 11 not only connects and attaches the third connecting plate 51, but also forms the first connecting groove 101 at a distance from the first protrusion 131; the second reinforcing plate 12 is not only used for connecting and attaching the third connecting plate 51 on another first section member, but also forms a second connecting groove 102 at a distance from the second protruding portion 132. Therefore, on one hand, the structure is simplified, and the connecting groove is formed without arranging a plurality of convex parts; on the other hand, when the third connecting plate 51 is secured to the outside of the first reinforcing plate 11 or the outside of the second reinforcing plate 12 in a seamless fit state, the lower second connecting protrusion 524 is not only locked in the first groove 101 or the second groove 102, but also the second connecting protrusion 524 is secured to the outside of the first reinforcing plate 11 or the outside of the second reinforcing plate 12 in a seamless fit state, so as to further improve the overall sealing performance.

In an actual coupling process, when the coupling end of the second fastening member 26 is gradually inserted into the second coupling base 134 through the second coupling hole, the second inclined surface 511 of the second coupling protrusion 524 contacts the third inclined surface 1310 of the first protrusion 131 and moves toward the groove bottom and the third coupling plate 51 moves toward a direction close to the first reinforcing plate 11; and/or, when the connection end of the second fastening member 26 is gradually inserted into the third connection base 135 through the second connection hole, the second inclined surface 511 of the second connection protrusion 524 contacts the fourth inclined surface 1320 of the second protrusion 132 and moves toward the groove bottom and the third connection plate 51 moves toward a direction approaching the second reinforcement plate 12.
