[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a double-sided color steel plate ventilation duct with a phenolic insulation interlayer, comprising: an outer color steel plate 1, an inner color steel plate 2, a phenolic insulation layer 3, a fixing chamber 4, a fixing rod 5, a sliding groove 6, a sliding block 7, a mounting frame 8, a fixing frame 9, a sliding rod 10, a spring 11, a hinge rod 12, a limiting rod 13, a pull rod 14, a sleeve 15, and a threaded rod 16.

[0026] First, as attached Figure 1 As shown, when ventilation ducts are used for ventilation, a phenolic insulation layer 3 is installed between the outer color steel plate 1 and the inner color steel plate 2. The outer side wall of the phenolic insulation layer 3 is fixedly connected to the inner side wall of the outer color steel plate 1, and the inner side wall of the phenolic insulation layer 3 is fixedly connected to the outer side wall of the inner color steel plate 2. This makes the outer color steel plate 1, the inner color steel plate 2 and the phenolic insulation layer 3 form a whole, so that the entire ventilation duct has good thermal insulation and thus keeps the internal temperature of the duct stable.

[0027] As attached Figure 1 Appendix Figure 2 and attached Figure 4As shown, when installing and splicing the pipeline, firstly, a set of outer color steel plates 1 are installed and fixed in the designated position, and then multiple sets of outer color steel plates 1 are spliced ​​together. When two sets of outer color steel plates 1 are spliced ​​together, the fixing rods 5 at the upper and lower ends of the front end of the outer color steel plate 1 come into contact with the limiting rods 13 on the side wall of the fixed chamber 4. At the same time, when two sets of outer color steel plates 1 are joined together, the fixing rods 5 drive the limiting rods 13 to slide inside the fixed chamber 4. Since the hinge rod 12 is in an inclined state and is rotatably connected to one end of the limiting rod 13 inside the fixed chamber 4 and the rear end of the sliding rod 10, the limiting rod 13 drives the sliding rod 10 to slide through the hinge rod 12. This also compresses the spring 11 sleeved on the outside of the sliding rod 10, and at the same time, causes the pull rod 14 to slide on the side wall of the fixed chamber 4. When two sets of outer color steel plates 1 are spliced ​​and attached together, the through hole on the rod body of the fixing rod 5 is used to drive the sliding rod 10 to reset through the elastic force of the spring 11. This causes the sliding rod 10 to drive the limiting rod 13 to reset through the hinge rod 12. The limiting rod 13 then engages with the through hole on the rod body of the fixing rod 5, thus completing the installation of multiple sets of outer color steel plates 1. When disassembling multiple sets of outer color steel plates 1, simply pull the pull clip 14. Since the pull clip 14 is fixedly connected to the rear end of the sliding rod 10, the sliding rod 10 drives the limiting rod 13 through the hinge rod 12 to form a telescopic structure. This allows the limiting rod 13 to contact and fix the two sets of outer color steel plates 1, thus simplifying the installation process, enabling rapid splicing, and reducing labor costs.

[0028] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 5 As shown, after the outer color steel plates 1 are spliced ​​together, the sliding blocks 7 at the left and right ends of the rear end of the outer color steel plates 1 can be pulled to make the sliding blocks 7 slide inside the slide groove 6. Then, when the sliding blocks 7 slide to a certain position inside the slide groove 6, they are rotatably connected to the mounting bracket 8. The mounting bracket 8 can then be rotated so that the threaded rod 16 at the rear end of the mounting bracket 8 corresponds to the fixed bracket 9. The threaded rod 16 passes through the fixed bracket 9 and is connected to the inner wall of the sleeve 15 by threads. The threaded rod 16 can then be rotated inside the sleeve 15, causing it to expand and contract inside the sleeve 15. The expansion and contraction of the threaded rod 16 allows it to fit together with the fixed bracket 9, thereby improving the overall strength and load-bearing capacity and enhancing the stability of the ventilation duct.

[0029] The content not described in detail in the specification belongs to the prior art known to those skilled in the art, the standard parts used in the utility model can be purchased from the market, the special-shaped parts can be ordered according to the description and the drawings, the specific connection mode of each part adopts the conventional means such as bolt, rivet and welding in the prior art, the machinery, parts and equipment adopt the conventional type in the prior art, and the circuit connection adopts the conventional connection mode in the prior art, which will not be described in detail here.

[0030] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
