Detailed Description
The following detailed description of embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 4-8, the present invention is an improved damper adjustment device.
The embodiment the improved air valve adjusting device comprises a fan blade 1, wherein the fan blade 1 comprises a main body 11 and connecting parts 12 at two ends, the main body 11 is of a smooth and flat structure, the plane of the main body 11 is of a circular structure, the main body 11 and the connecting parts 12 are of an integrated structure, and the connecting parts 12 are embedded in the main body 11. The two ends of the fan blade 1 are provided with a first knob 2 and a second knob 3 which are detachably connected with a connecting part 12, and the first knob 2 and the second knob 3 are respectively provided with a connecting rod which is connected with the connecting part 12. The connecting rod and the first and second knobs 2, 3 may be fixed or detachable structures, in this embodiment fixed structures. According to different requirements of users, the first knob 2 is of a T-shaped structure, and the second knob 3 is of a cylindrical toothed handle structure for preventing slipping. The first knob 2 is provided with a first sealing ring 4, the second knob 3 is provided with a second sealing ring 5, and the first sealing ring 4 and the second sealing ring 5 are hollow cylindrical structures. The first sealing ring 4 is sleeved on the connecting rod, and one end of the first sealing ring is attached to the first knob 2. In the same way, the second sealing ring 5 is sleeved on the connecting rod, and one end of the second sealing ring is attached to the second knob 3. According to the use requirement, the first sealing ring 4 and the first knob 2, and the second sealing ring 5 and the second knob 3 can be respectively glued.
Furthermore, the connecting portion 12 is of an arc-shaped outer eight-structure, each transition portion is in arc transition, and a thread is arranged in the connecting portion 12 and used for connection.
Further, the first knob 2, the second knob 3 and the connecting portion 12 are in threaded connection, that is, a threaded structure is arranged on the connecting rod.
Further, the section of the main body 11 in the fan blade 1 is in a fusiform structure with a thick middle part and thin two ends, and all transition positions are in arc transition.
