Description

Technical Field

[0001] The utility model relates to the technical field of air ducts, in particular to a color steel plate composite air duct. Background Art

[0002] Color steel plate composite air duct is an updated product of traditional glass fiber air duct, and a new generation substitute for galvanized iron air duct. It has the thermal insulation of traditional glass fiber air duct and the rigidity of galvanized iron air duct. The surface of the air duct is colored steel plate, which overcomes the fatal weaknesses of the previous glass fiber air duct, namely weak strength and easy damage of the outer wall, and gives full play to the advantages of galvanized iron.

[0003] In order to reduce the labor intensity of construction workers and shorten the construction period, color-coated steel plate composite air ducts are usually used instead of traditional iron sheet air ducts. However, in the existing technology, during the construction process of the color-coated steel plate composite air duct, the color-coated steel plate composite air duct may be too short, and the color-coated steel plate composite air duct needs to be connected and lengthened. The most commonly used connection method is to connect two color-coated steel plate composite air ducts with screws, but this connection method is not fast and convenient enough, thereby reducing work efficiency. In view of this, we propose a color-coated steel plate composite air duct. Utility Model Content

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0024] Example 1: A color steel plate composite air duct, see Figures 1 to 5 , including a duct body A1, a duct body B2 and a fixing component 3; the duct body B2 is connected to the duct body A1 through the fixing component 3;

[0025] like Figure 1 As shown, the air duct body A1 and the air duct body B2 of the present invention are color steel plate composite air ducts commonly found on the market.

[0026] like Figure 1-5 As shown, the fixing component 3 of this embodiment can be used to conveniently connect the duct body A1 and the duct body B2 when in use; specifically, the fixing component 3 includes a connecting block 301, a connecting plate 302, a fixing groove 303 and a fixing block 304; the connecting block 301 is fixed to the side of the duct body A1 close to the duct body B2; the connecting plate 302 is fixed to the side of the duct body B2 close to the duct body A1; a fixing groove 303 is opened on the connecting block 301; the fixing block 304 is inserted into the fixing groove 303, and the end of the fixing block 304 passes through the fixing groove 303 and is connected to the connecting plate 302. The utility model sets a fixing component 3. When the duct body B2 needs to be connected with the duct body A1, first, the fixing block 304 is inserted into the fixing groove 303. Then, the connecting plate 302 is moved toward the connecting block 301 to make the fixing block 304 slide in the fixing groove 303 until the bottom surface of the fixing block 304 contacts the bottom wall of the fixing groove 303. The utility model can quickly, conveniently and efficiently connect the duct body B2 with the duct body A1, which is conducive to improving work efficiency.

[0027] Specifically, the connection block 301 and the fixing block 304 are both in a U-shaped structure. The utility model sets the connection block 301 and the fixing block 304 in a U-shaped structure to facilitate fixing the position of the air duct body B2 and the air duct body A1.

[0028] Furthermore, the fixing assembly 3 also includes a reinforcing plate 305; the reinforcing plate 305 is fixed in the air duct body B2; wherein the reinforcing plate 305 is in an inclined structure, and the lower end of the reinforcing plate 305 is close to the air duct body A1, and the upper end of the reinforcing plate 305 is far away from the air duct body A1. The utility model sets the reinforcing plate 305 in an inclined structure, and sets the lower end of the reinforcing plate 305 close to the air duct body A1, and sets the upper end of the reinforcing plate 305 far away from the air duct body A1, so that when the air volume flows from the air duct body A1 to the air duct body B2, the air volume will hit the inclined surface of the reinforcing plate 305, so that the air duct body B2 can be more stably plugged into the fixing block 304 and the fixing groove 303 under the action of the air volume hitting the reinforcing plate 305, and the stability of the connection between the air duct body B2 and the air duct body A1 is further improved.

[0029] Furthermore, it also includes a sealing component 4; the sealing component 4 is arranged on the duct body A1, the duct body B2, the connecting block 301 and the connecting plate 302; wherein, the sealing component 4 includes a sealing block A401 and a sealing block B402; the sealing block A401 is fixed on the duct body A1 and the connecting block 301; the sealing block B402 is fixed on the duct body B2 and the connecting plate 302; wherein, the sealing block A401 and the sealing block B402 are both in a stepped structure; wherein, the sealing block A401 and the sealing block B402 constitute a stepped seal. The utility model provides sealing between the air duct body B2 and the air duct body A1 by setting sealing blocks A401 and sealing blocks B402, so as to prevent air from flowing out from between the air duct body B2 and the air duct body A1, thereby affecting the air tightness of the connection between the air duct body B2 and the air duct body A1. The sealing blocks A401 and B402 are both arranged in a stepped structure, and the sealing blocks A401 and B402 are arranged in a stepped seal, so as to extend the sealing path and increase the sealing effect.

[0030] It is worth noting that the sealing block A401 and the sealing block B402 are centrally symmetrically arranged; the inner wall size of the fixing groove 303 matches the size of the fixing block 304; when the bottom surface of the fixing block 304 contacts the inner bottom wall of the fixing groove 303, the sealing block A401 and the sealing block B402 contact each other. The utility model conveniently allows the sealing block A401 and the sealing block B402 to contact each other by centrally symmetrically arranging the sealing block A401 and the sealing block B402.

[0031] Working principle: When it is necessary to connect the duct body B2 with the duct body A1, first, insert the fixing block 304 into the fixing groove 303, and then move the connecting plate 302 toward the connecting block 301 to make the fixing block 304 slide in the fixing groove 303 until the bottom surface of the fixing block 304 contacts the bottom wall of the fixing groove 303. At this time, the sealing block A401 and the sealing block B402 contact each other, so that the duct body B2 and the duct body A1 have good sealing. When the air volume flows from the duct body A1 to the duct body B2, the air volume will hit the inclined surface of the reinforcement plate 305, so that the duct body B2 is more stably plugged into the fixing block 304 and the fixing groove 303 under the action of the air volume hitting the reinforcement plate 305, thereby further improving the stability of the connection between the duct body B2 and the duct body A1.
