What are the closing methods of the net cover?

2023-04-17

In the structure of the electric fan, in order to better prevent the fan blades from causing damage to the surrounding area during rotation, the front, rear, left, and right grilles have been modified, so that the fan blades are closed here. So, how to fix and close the front, rear, left and right grilles? There are several ways: 1. Fix it with screws. In the design of the edge of the grille, a small screw hole is added, so that it can be closed from front to back, from left to right, by changing the screw. This method is somewhat complicated in production and processing. After all, the screw holes are too small, and generally speaking, there are at least four holes. However, this method is relatively firm, and it is generally not easy to cause the front, rear, left, and right grilles to fall; 2. The outside is fixed. This method is mainly based on externally fixing a plastic ring tightly surrounding the net cover to close the net cover, and the joints of the plastic ring are also fixed by screws. This method is relatively simple, but if the plastic mesh bag is used for a long time or the screws are too tight, it will cause cracking.
