Problems solved by technology
However, in the process of assembly and disassembly of this structure, it is necessary to overcome the elastic force of the grille ring, and at the same time, it is necessary to use a screwdriver, which is cumbersome and time-consuming.
The second type is fastened together by a single buckle. Although the structure is simple, the buckle is easy to loosen and unstable, and may break when too much force is applied.
The third method is to fasten by setting elastic elements and pressing buckles. Although this fastening method overcomes the disadvantages of the above two technologies in the process of assembly, disassembly and use, the structure is relatively complicated, the assembly is cumbersome, and time-consuming

The invention discloses a net cover locking structure. The locking structure comprises a net cover ring and at least one lock catch, wherein lock catch mounting holes corresponding to the lock catches one by one are formed in the net cover ring; a connecting part is arranged at one end of each lock catch, and the connecting parts are connected to the inner side of the net cover ring in a rotating manner; a bending part is arranged at the other end of each lock catch, and the bending parts pass through the lock catch mounting holes to extend to the outer side of the net cover ring; a back net cover blocking structure is arranged between the connecting parts and the bending parts; an annular groove which is matched with the connecting end of a front net cover is formed in the inner side of the net cover ring. The net cover locking structure provided by the invention has the advantages of simple structure, convenience in assembly, firm buckling and low probability of falling off.
Description
technical field [0001] The invention relates to the field of electric fans, in particular to a net cover locking structure. Background technique [0002] The electric fan grille in the prior art is usually composed of two grilles connected front and rear, and the two grilles are combined by a grill ring. [0003] At present, there are three common connection methods in the prior art: the first one is to connect the connection holes through the openings on the grille ring, and to fix them by bolts. However, in the assembly and disassembly process of this structure, it is necessary to overcome the elastic force of the mesh cover ring and to use a screwdriver, which is cumbersome and time-consuming. The second type is fastened together by a single buckle. Although the structure is simple, the buckle is easy to loosen and is not secure, and may break when too much force is applied. The third method is to fasten by setting elastic elements and pressing buckles. Although this fa...
