Description

Technical Field

[0001] This utility model provides a conversion structure for air ducts and pipes used in special vehicles. Background Technology

[0002] Special vehicles are equipped with air conditioning systems, which typically include air conditioning units installed on the roof of the vehicle. These units deliver cool, warm, or natural air into the passenger compartment through ducts to regulate the temperature and create a comfortable environment for passengers. However, existing special vehicles suffer from space constraints that prevent the installation of these ducts. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a special vehicle air duct and duct conversion structure that is simple in structure, low in cost, aesthetically pleasing, and greatly reduces the installation difficulty of air ducts or ducts.

[0004] The technical solution adopted by this utility model is: a conversion structure for air duct and air pipe for special vehicles, including an air duct flange and a conversion structure body; the conversion structure body includes a cuboid box-shaped structure with one end open and an air pipe, the opening of the cuboid box-shaped structure is connected to the air duct flange; the air pipe is connected to the bottom plate of the cuboid box-shaped structure, and the central hole of the air pipe is connected to the inner cavity of the cuboid box-shaped structure.

[0005] In the aforementioned special vehicle air duct and duct conversion structure, the air duct flange is provided with multiple through holes.

[0006] In the aforementioned special vehicle air duct and air pipe conversion structure, the air pipe is circular, and an annular groove is provided at the air pipe connection port.

[0007] In the aforementioned special vehicle air duct and duct conversion structure, the number of through holes on the air duct flange is 8, and the diameter of the through holes is 7mm.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] This utility model has a simple structure, low cost, and beautiful appearance. It realizes the conversion between air duct and air pipe. When space is insufficient, the air duct can be converted into an air pipe for use, thereby meeting the relevant requirements of ventilation and cooling. It can also meet the needs of special vehicles for conversion of air duct shape and size due to insufficient space. Attached Figure Description

[0010] Figure 1 It is a structural diagram of the present utility model. Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] like Figure 1 As shown, this utility model includes a duct flange 1 and a conversion structure body. The conversion structure body includes a cuboid box-shaped structure 2 with one end open and a duct 3. The opening of the cuboid box-shaped structure 2 is connected to the duct flange 1. The duct flange 1 has eight φ7mm through holes, which can be used to connect the duct flange to the duct using eight M6 bolts. A sealing gasket is installed at the connection to ensure airtightness.

[0013] The air duct 3 is circular and is connected to the base plate of the cuboid box structure 2. The central hole of the air duct 3 communicates with the inner cavity of the cuboid box structure 2. An annular groove 31 is provided at the connection port of the air duct 3. The air duct is fitted onto the connection port of the air duct 3 and locked in the groove 31 with a clamp.

[0014] This invention transfers cold air from a duct or pipe to another duct or pipe for conversion. The dimensions can be adjusted according to the ventilation requirements of the air conditioning system or the space requirements of armored vehicles. It fulfills the need for conversion in shape and size of ducts in special vehicles due to space constraints, and has the advantages of convenient installation, simple structure, and aesthetically pleasing appearance.
