[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Examples, such as Figure 1 - Figure 4 As shown, this utility model provides a double-sided steel plate sandwich insulated air duct material, including a main body 1. A shock-absorbing and protective assembly 2 is provided at the bottom of the main body 1. The shock-absorbing and protective assembly 2 includes a protective frame 201. Connecting rods 202 are inserted into the inner walls of both the front and rear ends of the protective frame 201. First springs 203 are sleeved on both sides of the connecting rods 202. Sliding sleeves 204 are connected to the inner walls of both sets of first springs 203. A first rotating shaft 205 is connected to the top of the sliding sleeve 204. A support rod 206 is connected to the surface of the first rotating shaft 205. A second rotating shaft 207 is connected to one side of the support rod 206. A fixing frame 208 is connected to the center of the surface of the protective frame 201. The fixed frame 208 has two sets of second springs 209 connected inside, and the top of the two sets of second springs 209 is connected to a top block 210. The two sides of the protective frame 201 are connected to dampers 211, and the bottom surface of the protective frame 201 is connected to a rubber plate 212. The sliding sleeve 204 and the connecting rod 202 are slidably connected. The sliding sleeve 204 is rotatably connected to the support rod 206 through the first rotating shaft 205. The support rod 206 is rotatably connected to the plate body 1 through the second rotating shaft 207. The sliding sleeve 204 and the first spring 203 form an elastic structure. The top block 210 is rotatably connected to the second spring 209 through the fixed frame 208.

[0023] The effect achieved in Embodiment 1 is as follows: when the bottom of the main body 1 of the plate is impacted, the impacting object will first come into contact with the rubber plate 212, which will act as a protective barrier. Then, under the influence of rotation, the second rotating shaft 207 and the support rod 206 will rotate, and the support rod 206 will be able to rotate with the first rotating shaft 205. The first rotating shaft 205 will be able to push the sliding sleeve 204 to slide on the surface of the connecting rod 202, thereby compressing the first spring 203. At the same time, the top block 210 will also form an elastic structure between the fixing frame 208 and the second spring 209, which, together with the damper 211, will play a shock absorption and buffering role, thereby protecting the main body 1 of the plate and avoiding the problem of deformation of the air duct due to impact, which would affect normal use.

[0024] Example 2, as Figure 1 and Figure 4 As shown, the main body 1 of the board has a reinforcing component 3 inside. The reinforcing component 3 includes a sealing reinforcement layer 301. An insulation layer 302 is connected to the outside of the sealing reinforcement layer 301. A moisture-proof isolation layer 303 is connected to the outside of the insulation layer 302. A moisture-proof isolation layer 303 is connected to the outside of the moisture-proof isolation layer 303. The main body 1 of the board is made of steel plate.

[0025] The effect achieved in Embodiment 2 is as follows: the outer protective steel plate 304 can withstand external impacts, while the inner plate body 1 steel plate can maintain the shape of the air duct, the insulation layer 302 can reduce heat loss and prevent air leakage, and after the outer protective steel plate 304 resists physical damage, the moisture-proof isolation layer 303 can block water vapor penetration, prevent the thermal conductivity of the insulation layer 302 from increasing after absorbing water, and improve the overall practicality.

[0026] Working principle: When the bottom of the main body 1 of the plate is impacted by construction tools and equipment, the rubber plate 212 can provide protection, and the first spring 203, the second spring 209 and the damper 211 can provide shock absorption and buffering, thereby protecting the main body 1 of the plate, improving the service life of the air duct, and avoiding problems caused by impact affecting normal use. The moisture-proof isolation layer 303 can block water vapor penetration and prevent the insulation layer 302 from becoming damp and failing. The double-layer steel plate design can withstand external impacts, so that the inner steel plate maintains the shape of the air duct and improves the overall practicality.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
