For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0028] Reference Figure 1 and Figure 2As shown, the embodiment of the present application discloses an air conditioning damper device, which includes two frame side panels 1, a first frame head 2, a second frame head 3, a blade assembly 4 and a transmission assembly 5. The two frame side panels 1 are arranged at intervals, and each frame side panel 1 is provided with a plurality of mounting holes 102a. The plurality of mounting holes 102a can be used to install the frame side panel 1 on the target object to be installed (such as the air outlet or air inlet of the subway air conditioner) through a first connecting member (such as a bolt). The first frame head 2 is detachably connected to one end of the two frame side panels 1, and the second frame head 3 is detachably connected to the other end of the two frame side panels 1, so that the first frame head 2, the second frame head 3, and the two frame side panels 1 can enclose a receiving portion. The blade assembly 4 is received in the receiving portion, the transmission assembly 5 is inserted into the first frame head 2 and the second frame head 3, and the transmission assembly 5 is connected to the blade assembly 4 by plugging, and the transmission assembly 5 is used to drive the blade assembly 4 to rotate to open or close the receiving portion, thereby realizing the opening or closing of the air conditioning damper device.

[0029] In this embodiment, one end of the two frame side panels 1 is detachably connected to the first frame head 2 via a second connecting member (such as a bolt), and the other end of the two frame side panels 1 is detachably connected to the second frame head 3 via a third connecting member (such as a bolt).

[0030] The present embodiment eliminates the welding connection method by making the frame side panel 1 detachably connected to the first frame head 2 and the second frame head 3 (for example, by threads), thereby reducing the possibility of deformation of the frame side panel, and further more effectively ensuring the sealing between the blade assembly and the frame side panel, effectively reducing or even preventing air leakage of the air-conditioning damper device when closed. This is because, if welding is used, the frame side panel is likely to be deformed, and deformation of the frame side panel is likely to cause air leakage of the air-conditioning damper device. At the same time, when the air-conditioning damper device is severely deformed or damaged, the present embodiment can be disassembled on-site for repair, which is more convenient for repair.

[0031] In order to further reduce the possibility of deformation of the frame side panel 1, the air conditioning damper device also includes a plurality of reinforcing plates 9, which are evenly spaced and distributed along the length extension direction of the frame side panel 1, and the two ends of each reinforcing plate 9 are respectively connected to the two frame side panels 1. For example, the two ends of each reinforcing plate 9 can be riveted to the two frame side panels 1 by rivets. The position of at least part of the mounting holes 102a is set corresponding to the position of the reinforcing plate 9. For example, at least part of the mounting holes 102a are set close to the reinforcing plate 9. In this embodiment, the distance between at least part of the mounting holes 102a and the reinforcing plate 9 is less than a preset value, which can be 5 cm, 4 cm, 3 cm, etc. In this embodiment, by providing a reinforcing plate 9 between the two frame side panels 1 and making at least part of the mounting holes 102a close to the reinforcing plate 9, the frame side panel 1 can be effectively prevented from being pulled and deformed by the mounting bolts. Because, in the related art, when the frame side panel is installed on the target object to be installed through the mounting holes and bolts, the frame side panel is easily deformed by the pulling of the bolts. In this embodiment, when installing the frame side panel 1, the force applied to the frame side panel 1 by the reinforcing plate 9 can effectively prevent the frame side panel 1 from being deformed by the pulling of the mounting bolts. At the same time, the reinforcing plate 9 can also be used as a temperature detector mounting bracket. Therefore, the provision of the reinforcing plate 9 also facilitates the installation of the temperature detector.

In this embodiment, four threaded plates 6 are provided, of which two threaded plates 6 are respectively arranged on opposite sides of the first frame head 2, and the two threaded plates 6 located on opposite sides of the first frame head 2 can be riveted to the two sides of the first frame head 2 by rivets, and the other two threaded plates 6 are respectively arranged on opposite sides of the second frame head 3, and the two threaded plates 6 located on opposite sides of the second frame head 3 can be riveted to the two sides of the second frame head 3 by rivets. The two frame side panels 1 are respectively located on both sides of the first frame head 2 and the second frame head 3, and one end of the two frame side panels 1 can be threadedly connected to the two threaded plates 6 located on both sides of the first frame head 2 through bolts (i.e., the second connecting member), and the other ends of the two frame side panels 1 are threadedly connected to the two threaded plates 6 located on both sides of the second frame head 3 through bolts (i.e., the third connecting member), so that the two frame side panels 1, the first frame head 2 and the second frame head 3 are enclosed into a rectangular frame with a receiving portion.

During assembly, the driving shaft 51 is passed through the first through hole, the first driven shaft 52 is passed through the second through hole, the second driven shaft 53 is passed through the third through hole, and the third driven shaft 54 ​​is passed through the fourth through hole. The first connecting hole 551 of the connecting rod 55 is sleeved on the first connecting column 531, and the second connecting hole 552 of the connecting rod 55 is sleeved on the second connecting column 541. The gasket 56, the anti-slip pad 57 and the nut 58 are sequentially sleeved on the first connecting column 531 and the second connecting column 541, so that the second driven shaft 53 and the third driven shaft 54 ​​can be movably connected through the connecting rod 55.

[0035] Continue to refer to Figure 5 and Figure 6As shown, the air conditioner damper device also includes a mounting plate 11 and a plurality of partitions 10. The mounting plate 11 is arranged on the side of the first frame head 2 facing away from the blade assembly 4, and the mounting plate 11 can be riveted to the first frame head 2 by rivets. The mounting plate 11 can be used to install the damper actuator, and the damper actuator can be used to control the rotation of the driving shaft 51. At least one partition 10 is arranged between the first end of the blade assembly 4 and the first frame head 2, and at least one partition 10 is arranged between the second end of the blade assembly 4 and the second frame head 3. The driving shaft 51 is penetrated by the mounting plate 11, the first frame head 2 and the corresponding partition 10, and the first driven shaft 52 is penetrated by the first frame head 2 and the corresponding partition 10.
