Description

Technical Field

[0001] The invention belongs to the technical field of household electrical appliances, and in particular relates to a mesh cover locking component for an electric fan and an electric fan comprising the mesh cover locking component. Background Art

[0002] As is known to all, the front and rear mesh covers on the electric fan are welded by metal wires, and the two need to be locked with the aid of a mesh cover locking component. The existing mesh cover locking component mainly includes a ring sleeve and a front limiting structure and a rear limiting structure arranged on the inner side thereof, and a locking mechanism composed of a flip lock, a screw, a front hook and a rear hook. During use, the ring sleeve is firstly put on the front and rear mesh covers and the front and rear limiting structures are respectively engaged with the edges of the front and rear mesh covers, and then the flip lock is rotated to force the front and rear hooks arranged thereon to enter the through hole and engage with the edges of the front and rear mesh covers, and finally the flip lock is fixed to the ring sleeve by a screw to prevent the front and rear hooks from withdrawing from the through hole, thereby completing the locking of the front and rear mesh covers by the mesh cover locking component. Although the mesh cover locking component locks the front mesh cover and the rear mesh cover together, it requires that there should be no gap between the ring sleeve and the mesh cover, otherwise the front mesh cover and the rear mesh cover cannot be firmly locked together, which leads to excessively high manufacturing precision of the ring sleeve, increases the scrap rate of the ring sleeve, and increases the manufacturing cost of the mesh cover locking component. Summary of the invention

[0003] In order to solve all or part of the above problems, the purpose of the present invention is to provide a mesh cover locking component for an electric fan and an electric fan, which can solve the problem of excessive manufacturing precision of the ring sleeve and improve the qualified rate of the ring sleeve, thereby effectively reducing the manufacturing cost of the mesh cover locking component.

[0004] According to a first aspect of the present invention, a mesh cover locking component for an electric fan is provided, comprising: a ring sleeve; a front limiting structure and a rear limiting structure, all of which are arranged on the inner side of the ring sleeve, and the front limiting structure and the rear limiting structure can limit the front mesh cover and the rear mesh cover from being separated from the ring sleeve when the ring sleeve tightens the front mesh cover and the rear mesh cover of the electric fan; a clamping mechanism, which comprises a through hole arranged on the ring sleeve, a flip buckle pivotally connected to the ring sleeve, and a locking member arranged on the flip buckle and the ring sleeve, the flip buckle having a pivot end, a movable end, a connecting portion connecting the pivot end and the movable end, and a protruding portion arranged on the connecting portion; wherein the flip buckle is arranged to be manipulated so that its movable end gradually approaches the ring sleeve, and the protruding portion of the flip buckle is pressed against the front mesh cover and / or the rear mesh cover of the electric fan after passing through the through hole, so that the ring sleeve can be locked by the locking member and continuously tightened on the front mesh cover and the rear mesh cover.

[0005] As can be known from the above technical scheme, the screen locking component of the present invention is provided with a protrusion on the overturning buckle of the clamping mechanism, so no matter whether there is a gap between the ring sleeve and the screen, the protrusion of the overturning buckle can pass through the through hole and press on the front screen and / or the rear screen of the electric fan, so that the ring sleeve is continuously and effectively tightened on the front screen and the rear screen under the locking action of the locking member, ensuring that the front limiting structure and the rear limiting structure safely limit the front screen and the rear screen from the ring sleeve, and realizing the locking of the front screen and the rear screen by the screen locking component. In other words, no matter whether there is a gap between the ring sleeve and the screen, the screen locking component can firmly lock the front screen and the rear screen together, which can greatly reduce the manufacturing accuracy of the ring sleeve, improve the qualified rate of the ring sleeve, and then effectively reduce the manufacturing cost of the screen locking component. At the same time, the screen locking component for electric fans of the present invention has a compact structure, is easy to assemble, is safe and reliable to use, and is convenient for implementation and promotion.

[0006] According to a second aspect of the present invention, there is provided an electric fan, comprising the mesh cover locking component according to the first aspect of the present invention. Since the electric fan according to the second aspect of the present invention comprises the mesh cover locking component, the manufacturing accuracy of the ring sleeve can be reduced, the qualified rate of the ring sleeve can be improved, and the manufacturing cost of the mesh cover locking component can be effectively reduced.
