Description

Technical Field

[0002] In modern buildings and industrial facilities, efficient operation of ventilation systems is essential to maintaining a good indoor environment, ensuring the normal operation of equipment, and saving energy and reducing emissions. As a key component in the ventilation system, the damper controls the flow and direction of air. In the past, the design of damper blades was relatively simple and had limited adjustment functions. As the performance requirements for ventilation systems in the construction and industrial fields continue to increase, the limitations of traditional damper blades have become increasingly prominent, so a damper blade with an adjustment structure is needed.

[0003] The patent document with the existing technical announcement number CN220082139U provides a damper blade with an adjustment structure, including a damper body; the damper body is provided with a first circular hole at both ends near the middle position, and the damper body is provided with a second circular hole at both ends near the edges; the damper body is provided with a first damper blade, a second damper blade and a third damper blade, and an adjustment mechanism is provided between the damper body and the first damper blade, the second damper blade and the third damper blade; through the design of the adjustment mechanism, the damper can be adjusted after adjustment. The function of fixing the position of the blades solves the problem that the existing air valve is not provided with a component for fixing the air valve after the angle is adjusted, and is only fixed by the engagement between various gears. If the air volume is large, it is very easy for the angle of the air valve blade to shift, and the position of the air valve blade cannot be fixed. The stability of the air valve during operation is improved. However, when the CN220082139U technology is operated, it is not convenient to adjust the length of the device according to the size of the air valve, and it is not convenient to seal the gap of the device, and the sealing effect is not good. Therefore, there is an urgent need for a air valve blade with an adjustment structure. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a wind valve blade with an adjustment structure, including a blade body, the outer wall of the blade body is welded with a limit strip, the outer wall of the limit strip is installed with an extension sleeve, the inner wall of the extension sleeve is abutted with a spring, and the outer wall of the extension sleeve is bonded with a first rubber pad.

[0006] An adjusting sleeve is installed on the outer wall of the blade body, a connecting rod is welded on one side of the adjusting sleeve, and a second rubber pad is bonded to the outer wall of the adjusting sleeve.

[0007] Preferably, the extension sleeve forms a lifting structure with the blade body through a limiting strip, and the extension sleeve is arranged at equal intervals on the outer wall of the blade body.

[0008] Preferably, the extension sleeve is arranged perpendicular to the spring, and the inner wall of the extension sleeve is of slotted design.

[0009] Preferably, the outer wall of the extension sleeve is tightly fitted with the outer wall of the first rubber pad, and the length of the outer wall of the extension sleeve is the same as the length of the outer wall of the first rubber pad.

[0010] Preferably, the adjusting sleeve is movably connected to the blade body, and the adjusting sleeve is symmetrically arranged with respect to the central axis of the blade body.

[0011] Preferably, the outer wall of the adjustment sleeve is tightly fitted with the outer wall of the second rubber pad, and the adjustment sleeve is symmetrically arranged with respect to the central axis of the second rubber pad.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model provides an extension sleeve to closely fit the first rubber pad. When the device is used, the extension sleeve and the first rubber pad are convenient for sealing the gap of the device, which has a better sealing effect and increases the usability of the device;

[0014] 2. The utility model activates the blade body by setting the adjusting sleeve. When the device is used, the setting of the adjusting sleeve and the blade body facilitates the length adjustment of the device according to the size of the air valve, thereby increasing the usability of the device.
