[0028] Please refer to Figures 1-5 , the downspout structure of the passive house exterior wall, including the main body 1, the fixing mechanism and the clamping mechanism. The fixing mechanism includes a fixing plate 2, a heat insulation pad 3, a fixing bolt 4, an expansion cylinder 5 and a bolt plate 6. The fixing plate 2 is detachably connected to the main body 1. The heat insulation pad 3 is detachably connected to the fixing plate 2. The fixing bolt 4 passes through the fixing plate 2 and is detachably connected to the exterior wall. The expansion cylinder 5 is threadedly engaged with the fixing bolt 4. The bolt plate 6 is installed inside the fixing plate 2 and is detachably connected to the fixing plate 2 through the fixing bolt 4. The clamping mechanism includes a spring 7, a clamping block 8, a rainproof plate 9 and an outer attached plate 10. The spring 7 is installed inside the fixing plate 2, and its two ends are respectively fixedly connected to the fixing plate 2 and the clamping block 8. The clamping block 8 is installed inside the outer attached plate 10 and is slidably connected to the outer attached plate 10. The rainproof plate 9 is detachably connected to the clamping block 8. The outer attached plate 10 is detachably connected to the fixing plate 2 through the clamping block 8.

[0029] In this embodiment, the fixing mechanism includes a fixing plate 2, a heat insulation pad 3, fixing bolts 4, an expansion cylinder 5, and a bolt plate 6. During use, a hole is drilled in the wall, and the expansion cylinder 5 is directly placed into the drilled hole. Then, the heat insulation pad 3 is placed into the placement groove 11 inside the fixing plate 2, and the bolt plate 6 is placed into the fixing groove 13 inside the fixing plate 2. Subsequently, the fixing bolts 4 are inserted. The fixing bolts 4 are slowly inserted into the expansion cylinder 5 by the action of power tools. Due to its shape, the expansion cylinder 5 expands inside the wall, thus firmly fixing the fixing plate 2 to the outer wall. And due to the fixation of the bolt plate 6, the firmness of the fixing plate 2 on the outer wall is more stable.

[0030] In this embodiment, the clamping mechanism includes a spring 7, a clamping block 8, a rainproof plate 9, and an outer attachment plate 10. When the fixing plate 2 is fixed to the wall, the main body 1 is placed on the fixing plate 2 at this time. After the end 14 on the main body 1 is placed on the fixing plate 2, the outer attachment plate 10 is placed on the fixing plate 2. During this process, the clamping block 8 is squeezed by the clamping hole 12, so that the clamping block 8 slides inside the outer attachment plate 10. The sliding block 17 and the connecting plate 19 on the clamping block 8 slide inside the first sliding groove 15, and the convex block 18 on the connecting plate 19 slides inside the second sliding groove 16, so that the convex block 18 slides on the through rod 21 in the second sliding groove 16 and squeezes the spring 7. When the clamping block 8 enters the clamping hole 12, the spring 7 resets inside, so that the clamping block 8 is placed in the clamping hole 12, thus fixedly connecting the outer attachment plate 10 and the fixing plate 2. Then, the rainproof plate 9 is placed on the outer attachment plate 10, and the opening 22 of the rainproof plate 9 coincides with the sliding block 17, thus completing the clamping and fixing. And when disassembling, the rainproof plate 9 is removed, and then the sliding block 17 is pulled, so that the sliding block 17 directly contacts the stop block 20, and the clamping block 8 disengages from the clamping hole 12, thus completing the disassembly of the outer attachment plate 10.

[0031] Embodiment 2:

[0032] In summary, during use, first fix the fixing plate 2. At this time, drill a hole in the wall, directly place the expansion cylinder 5 into the drilled hole, and place the heat insulation pad 3 into the placement groove 11 inside the fixing plate 2. Then place the bolt plate 6 into the fixing groove 13 inside the fixing plate 2. Subsequently, insert the fixing bolt 4, and the fixing bolt 4 is slowly inserted into the expansion cylinder 5 under the action of a power tool. Due to its shape, the expansion cylinder 5 expands inside the wall, thereby firmly fixing the fixing plate 2 to the outer wall. And due to the fixation of the bolt plate 6, the firmness of the fixing plate 2 on the outer wall is more stable. Then start installing the main body 1. At this time, place the main body 1 on the fixing plate 2. After the end 14 on the main body 1 is placed on the fixing plate 2, place the outer attachment plate 10 on the fixing plate 2. During this process, the clamping block 8 is squeezed by the clamping hole 12, so that the clamping block 8 slides inside the outer attachment plate 10, and the sliding block 17 and the connecting plate 19 on the clamping block 8 slide inside the first sliding groove 15, while the convex block 18 on the connecting plate 19 slides inside the second sliding groove 16, so that the convex block 18 slides on the through rod 21 in the second sliding groove 16 and squeezes the spring 7. When the clamping block 8 enters the clamping hole 12, the spring 7 resets inside, so that the clamping block 8 is placed in the clamping hole 12, thereby fixedly connecting the outer attachment plate 10 and the fixing plate 2. Then place the rain shield 9 on the outer attachment plate 10, and the opening 22 of the rain shield 9 is aligned with the sliding block 17, thus completing the clamping and fixing. And when disassembling, remove the rain shield 9, then pull the sliding block 17 so that the sliding block 17 directly contacts the stop block 20, and the clamping block 8 disengages from the clamping hole 12, thus completing the disassembly of the outer attachment plate 10.
