Description

Technical Field

[0001] The utility model relates to the field of central air-conditioning frames, in particular to a high-precision central air-conditioning frame for a rail vehicle. Background Art

[0002] The central air conditioning system of a rail vehicle refers to an air conditioning system installed in the train body. It can adjust parameters such as temperature, humidity, and air flow speed in the car to ensure the comfort of passengers during the journey. The central air conditioning frame refers to the metal or alloy frame structure used to support and fix the air conditioning equipment inside the car. These frames are usually customized by professional manufacturers according to the specific vehicle design and need to meet the relevant technical standards and safety regulations. For rail trains, the air conditioning system is an important part of the train. The air conditioning unit is generally installed on the top of the vehicle and adopts an integrated structure. When the height of the train needs to be lowered, the air conditioning unit is often installed in other parts of the train, such as the bottom of the vehicle.

[0003] In actual use, the existing central air-conditioning frame mechanism for rail vehicles has a relatively fixed wind speed, and passengers cannot adjust the wind direction and wind speed according to their own conditions, which brings a bad experience to passengers. In addition, the air-conditioning frame is relatively fixed, which makes it inconvenient to clean the inside of its wind blades, reducing work efficiency. Utility Model Content

[0005] To achieve the above-mentioned purpose, a high-precision central air-conditioning rack for rail vehicles is provided, comprising a rack body, a central air-conditioning air outlet box is installed at the bottom of the rack body, and a top seat is fixedly installed on the surface of the central air-conditioning air outlet box, and rotating shafts are installed at both ends of the top seat, and the rotating shaft is movably connected to the connecting piece at the bottom of the rack body through a bearing, and a plurality of groups of air holes are evenly arranged on the bottom surface of the central air-conditioning air outlet box; an air-conditioning air duct is welded and fixed on the side wall of the central air-conditioning air outlet box, and a connecting flange is installed at the end of the air-conditioning air duct, and the end of the air-conditioning air duct is connected to the central air-conditioning air outlet hose through the connecting flange.

[0006] Preferably, the cross-section of the central air-conditioning air outlet box is a semicircular structure.

[0007] Preferably, two sets of limit blocks are installed on both sides of the bottom of the central air-conditioning air outlet box, and the limit blocks are installed inside the limit grooves. At the same time, the sizes of the limit blocks and the limit grooves are matched, and the limit blocks are slidably arranged inside the limit grooves.

[0008] Preferably, the limiting groove is provided inside the limiting rail, and the top of the limiting rail is fixedly connected to the frame body, and the limiting rail is arranged in an arc shape.

[0009] Preferably, the limiting track, the rotating shaft and the central air-conditioning air outlet box are concentric circle structures.

[0010] Preferably, the top of the rotating shaft is fixedly connected to the guide block, and the guide block is slidably arranged inside the guide seat. At the same time, a guide groove is opened at the bottom of the guide seat, and a connecting frame is fixedly installed on the top of the guide seat, and the top of the connecting frame is fixedly installed on the bottom of the frame body.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the air-conditioned air enters the interior of the central air-conditioning air outlet box from the hose, and is discharged from a large number of air holes, blowing on the passengers. By holding the central air-conditioning air outlet box, the air outlet angle at the bottom of the central air-conditioning air outlet box can be adjusted. The friction between the limit block, the limit groove, the guide seat and the guide block can ensure the stability of the central air-conditioning air outlet box when it is stationary, and there will be no shaking. Passengers can adjust it according to their own physical needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] See also Figure 1-5The utility model provides a high-precision central air-conditioning rack for rail vehicles, including a rack body 9, a central air-conditioning air outlet box 1 is installed at the bottom of the rack body 9, and a top seat 5 is fixedly installed on the surface of the central air-conditioning air outlet box 1, and rotating shafts 6 are installed at both ends of the top seat 5, and the rotating shaft 6 is movably connected to the connecting piece at the bottom of the rack body 9 through a bearing, and a plurality of groups of air holes 4 are evenly arranged on the bottom surface of the central air-conditioning air outlet box 1; an air-conditioning duct 2 is welded and fixed on the side wall of the central air-conditioning air outlet box 1, and a connecting flange is installed at the end of the air-conditioning duct 2, and the end of the air-conditioning duct 2 is connected to the central air-conditioning air outlet hose through the connecting flange.

[0019] Working principle: When in use, the conditioned air generated by the central air-conditioning enters the interior of the central air-conditioning air outlet box 1 from the hose, and is discharged from a large number of air holes 4 to blow on the passengers. By holding the central air-conditioning air outlet box 1, the air outlet angle at the bottom of the central air-conditioning air outlet box 1 can be adjusted. The friction between the limit block 3, the limit groove 8 and the guide seat 10 and the guide block 11 can ensure the stability of the central air-conditioning air outlet box 1 when it is stationary, and there will be no shaking. Passengers can adjust it according to their own physical needs.

[0020] As a preferred embodiment, the cross-section of the central air-conditioning air outlet box 1 is a semicircular structure.

At the same time, the sizes of the limit blocks 3 and the limit grooves 8 are adapted, and the limit blocks 3 are slidably set inside the limit grooves 8.

[0022] like Figure 1-4 As shown: the limit block 3 is slidably set inside the limit groove 8, and there is a damping friction force between the limit block 3 and the limit groove 8. This friction force is greater than the gravity of the central air-conditioning air outlet box 1, thereby ensuring the stability of the central air-conditioning air outlet box 1 when it is stationary.

By holding the central air-conditioning air outlet box 1, it is convenient to adjust the air outlet direction of the air hole 4 at the bottom of the central air-conditioning air outlet box 1 to adapt to the needs of different passengers. In order to further ensure the stability between the limit block 3 and the limit groove 8, bolts can be clamped between the limit block 3 and the limit groove 8 to ensure the stability of the central air-conditioning air outlet box 1 when it is tilted.

[0026] As a preferred embodiment, the top of the rotating shaft 6 is fixedly connected to the guide block 11, and the guide block 11 is slidably arranged inside the guide seat 10. At the same time, a guide groove is opened at the bottom of the guide seat 10, and a connecting frame 12 is fixedly installed on the top of the guide seat 10, and the top of the connecting frame 12 is fixedly installed on the bottom of the frame body 9.
