Description

Technical Field

[0001] The utility model relates to the technical field of fans, and particularly relates to a fan grille. Background Art

[0002] The existing fan grille generally includes a first grille and a second grille. The first grille and the second grille are closed towards each other and are detachably connected. Both the first grille and the second grille are formed by welding multiple spokes radially centered and multiple iron rings of different sizes. The outer edges of the first grille and the second grille are respectively provided with a first flat ring and a second flat ring. The diameters of the first flat ring and the second flat ring are the same. The first flat ring is provided with four through holes and four connecting screws, and the second flat ring is provided with four screw holes corresponding to the positions of the four through holes. The connecting screws pass through the through holes and are threadedly connected with the screw holes, thereby realizing the connection of the first grille and the second grille. Every time a user disassembles and assembles the first grille and the second grille, four connecting screws need to be removed. Therefore, the structure of the above fan grille is complex, the disassembly and assembly are cumbersome, and it is inconvenient. Content of the Utility Model

The first flat ring is located within the openings of the three fixing cards. The second flat ring is inserted into the openings of the three fixing cards. The first flat ring is provided with a through hole and a connecting screw, and the second flat ring is provided with a screw hole corresponding to the position of the through hole. The connecting screw passes through the through hole and is threadedly connected with the screw hole. The three fixing cards effectively prevent the first flat ring and the second flat ring from separating from each other and the first grille and the second grille from detaching. The first flat ring and the second flat ring of the utility model are pre-fixed together by three fixing cards. The first grille and the second grille are closed, and then a screw is used to lock the first grille and the second grille. Therefore, the structure of the utility model is simple, and the disassembly and assembly are convenient.

[0006] The utility model can be further improved as follows.

[0007] Positioning grooves are provided on the second side plates of the fixing cards, and the spokes of the second grille are clamped into the positioning grooves.

[0008] The through hole is located at the lower position of the first flat ring.

[0009] The beneficial effects of the present utility model are as follows:

[0010] The first flat ring and the second flat ring of the present utility model are pre-fixed together by three fixing plates. The first mesh cover and the second mesh cover are closed, and then a screw is used to lock the first mesh cover and the second mesh cover. Therefore, the structure of the present utility model is simple and convenient for disassembly and assembly. Description of the Drawings

[0017] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0018] Embodiment 1, as Figures 1 to 6 shown, a fan mesh cover includes a first mesh cover 1 and a second mesh cover 2 that are detachably connected. The outer edges of the first mesh cover 1 and the second mesh cover 2 are respectively provided with a first flat ring 11 and a second flat ring 21. The first flat ring 11 and the second flat ring 21 are mutually attached. Three fixing plates 3 are annularly and spacedly arranged on the first mesh cover 1. The three fixing plates 3 are arranged on the first flat ring 11 according to the positions of the left part, upper part, and right part of the first flat ring 11. The fixing plates 3 are in a U shape. The openings of the three fixing plates 3 all face the center of the first flat ring 11. The first side plates 31 of the three fixing plates 3 are fixedly connected to the first flat ring 11. The first flat ring 11 is located within the openings of the three fixing plates 3. The second flat ring 21 is inserted into the openings of the three fixing plates 3. A through hole 12 and a connecting screw 4 are provided on the first flat ring 11. A screw hole 22 is provided at the position corresponding to the through hole 12 on the second flat ring 21. The connecting screw 4 passes through the through hole 12 and is threadedly connected to the screw hole 22.

[0019] As a more specific technical solution of the utility model.

[0020] A positioning groove 33 is provided on the second side plate 32 of the fixed clamping plate 3, and the spokes of the second wire mesh cover 2 are clamped into the positioning groove 33.

[0021] The through hole 12 is located at the lower position of the first flat ring 11.

[0022] The working principle of the utility model is as follows:

[0023] When assembling the first wire mesh cover 1 and the second wire mesh cover 2 of the utility model, the user first picks up the first wire mesh cover 1, and then keeps the first flat ring 11 in contact with the second flat ring 21, but the first flat ring 11 and the second flat ring 21 are placed vertically offset, with the first flat ring 11 above the second flat ring 21. The three fixed clamping plates are respectively aligned directly above the left part, the upper part, and the right part of the second flat ring 21. Then, the user moves the first wire mesh cover 1 downward along the second flat ring. The openings of the three fixed clamping plates 3 move towards the second flat ring 21. The positioning groove of the middle fixed clamping plate 3 aligns with the spokes of the second wire mesh cover. After that, the second flat ring 21 is inserted upward into the openings of the three fixed clamping plates 3 until the first flat ring 11 and the second flat ring 21 completely overlap. The spokes of the second wire mesh cover are clamped upward into the positioning groove, and the position of the through hole 12 is aligned with the screw hole 22. Then, the user passes the connecting screw 4 through the through hole 12 and tightens it with the screw hole 22, thereby realizing the assembly of the first wire mesh cover 1 and the second wire mesh cover 2. On the contrary, when the user wants to disassemble the first wire mesh cover 1 and the second wire mesh cover 2, the user only needs to unscrew the connecting screw 4, and then pull out the first wire mesh cover 1 upward. The three fixed clamping plates 3 are separated from the second flat ring 21, and the first flat ring is separated from the second flat ring 21, thereby realizing the disassembly of the first wire mesh cover 1 and the second wire mesh cover 2.
