Among them, an installation groove 16 is opened inside the support cylinder 10, a buffer spring 15 is installed on the inner bottom wall of the installation groove 16, and a positioning block 14 is installed at one end of the buffer spring 15 away from the installation groove 16. Among them, the bottom of the docking rod 9 is fixedly connected to the top of the positioning block 14, so that the docking rod 9 can maintain an upward movement trend through the elastic force of the buffer spring 15 stretching and contracting. At the same time, when the docking rod 9 is subjected to a downward extrusion force, there can be a certain buffer between the docking rod 9 and the support cylinder 10. A docking block 7 is installed on the side wall of the upper housing 1, a card slot 12 is opened on the side wall of the docking block 7, and a limiting component is arranged on the card slot 12 for limiting the docking rod 9 inside the card slot 12. Among them, an opening is opened on one side of the card slot 12 close to the docking block 7. Among them, the docking rod 9 passes through the opening and is engaged with the card slot 12. Thus, when the upper housing 1 moves from right to left, the docking block 7 can be engaged outside the docking rod 9, enabling the upper housing 1 and the intermediate housing 4 to quickly complete docking. Among them, the limiting component includes a second screw 8 movably connected to the front wall of the docking block 7, and a second threaded hole 13 opened on the inner wall of the card slot 12. Among them, the second screw 8 is threadedly connected to the second threaded hole 13 for limiting the docking rod 9 inside the card slot 12. Among them, a limiting block 6 is installed on the top of the docking rod 9. Among them, the diameter of the lower surface of the limiting block 6 is larger than the inner diameter of the card slot 12, so that the docking rod 9 can be stably engaged inside the docking block 7, avoiding the situation of falling off, so that the upper housing 1 and the intermediate housing 4 achieve the effect of quick and stable docking. A threaded component is arranged between the upper housing 1 and the intermediate housing 4. Among them, the threaded component includes a first screw 2 movably connected to the upper housing 1, and a first threaded hole 3 opened on the intermediate housing 4. Among them, the first screw 2 is threadedly connected to the first threaded hole 3, so that the upper housing 1 and the intermediate housing 4 can be quickly assembled by the threaded connection of the first screw 2 and the first threaded hole 3. The connection method between the lower housing 5 and the intermediate housing 4 is the same as that between the upper housing 1 and the intermediate housing 4, so that the upper housing 1, the intermediate housing 4, and the lower housing 5 achieve the effect of quick docking and assembly.

[0025] Working principle: When assembling the upper housing 1 and the middle housing 4, move the hoisted upper housing 1 from right to left until the docking block 7 is moved to the outside of the docking rod 9, and the docking rod 9 is completely located inside the card slot 12. Then tighten the second screw 8 to completely lock the docking rod 9 inside the card slot 12, and then tighten the first screw 2, so as to achieve the effect of rapid docking and assembly of the upper housing 1 and the middle housing 4. At the same time, the docking method of the lower housing 5 and the middle housing 4 is the same, thus achieving the effect of rapid docking and assembly of the flue gas heat exchanger.
