Embodiment

It is shown referring to the drawings, the utility model ventilating opening structure is further illustrated.

Embodiment：A kind of ventilating opening structure, including shutter frame and filter plate 2, are tied by shutter frame and the double-deck of filter plate 2 Structure causes it to have more preferable isolation effect, due to being provided that tiny filter bores 23 on interior side filter plate 2, plays certain anti- Dirt is acted on, also, the biology such as worm ant can not enter case and become etc. in equipment and go, it is therefore prevented that worm ant is to internal component or thing The destruction of product.Wherein, shutter frame includes frame 1 and is arranged on some blades 11 in the center of frame 1, and the edge of filter plate 2 is outside The first flanging 21 is convexed to form, the inner side of the first flanging 21 is provided with locating dowel 24, formed between the first flanging 21 and locating dowel 24 Gap 25, the medial surface of frame 1 is provided with outwardly flange 13, and flange 13 is held in gap 25.So, in installation frame 1 with filter plate 2 when, it is only necessary to the flange 13 of frame 1 is clamped in gap 25, by the first flanging 21 with locating dowel 24 to convex Edge 13 produces chucking power so that filter plate 2 is fixed on frame 1.The attachment structure of this clamping not only causes frame 1 and filter plate 2 Connective stability it is higher, and cause both easy disassembly.

Secondly, outwards vertical turnover forms the second flanging 22 to the first flanging 21, so, dismount frame 1 and filter plate 2 when Wait, be easy to separate both, it is only necessary to which hand holds on the second flanging 22, it becomes possible to easily stick into filter plate 2 in gap 25, Or extract filter plate 2.

Furthermore, in order that the connection of frame 1 and filter plate 2 is more fixed.In the present embodiment, the inner side correspondence of flange 13 is positioned The position of post 24 is provided with fixed column 14, and dismountable fixture is connected between fixed column 14 and locating dowel 24, passes through fixture Further fixation enable to the connection of frame 1 and filter plate 2 more to fasten.

Wherein, run through in locating dowel 24 provided with perforation 241, fixture is threadedly connected in fixed column 14 through perforation 241. Fixed column 14 is provided with fixing hole 141, and fixture is screw, and screw is threadedly coupled through perforation 241 with fixing hole 141.Due to The frame 1 can typically use injection molding with filter plate 2, so commonly using threaded connection, screw thread can be caused easily to fail.Institute Further, metal threaded set 15 is installed with fixing hole 141, the inwall of the metal threaded set 15 sets internal thread, outer wall It is heat-fused in fixing hole 141, then, screw is threadedly coupled with metal threaded set 15.In addition, the perforation 241 can be counter sink, So, the head of screw can be arranged in perforation 241.

In addition, the present embodiment is also made that improvement to shutter frame, wherein, reinforcing is connected between adjacent blade 11 and is connected Fishplate bar 12, reinforces connecting plate 12 and is set perpendicular to blade 11.Because the length of shutter frame is longer, and if blade 11 itself is longer When, then easily snap off.After reinforcing connecting plate 12 is provided with, it is capable of the bending resistance of reinforced blade 11, it is to avoid fracture.

Wherein, end face of the connecting plate 12 close to the side of filter plate 2 is reinforced to flush with the edge of flange 13.So, in blinds After window frame coordinates with filter plate 2, the inner surface of filter plate 2 can be supported with reinforcing connecting plate 12 to be set so that the fastening strength of filter plate 2 is obtained To enhancing, so, filter plate 2 is also not easy to be destroyed in the case of stress.The reinforcing connection of centre is only needed in the present embodiment End face of the plate 12 close to the side of filter plate 2 is flushed with the edge of flange 13, can not only so reach the reinforcing structure of filter plate 2 The effect of intensity, also with saving material, it is easy to the advantage of injection.

Further, blade 11 is Z-shape is set, including middle swash plate 111, and middle swash plate 111 is relative to vertical plane It is obliquely installed, it has effect that is dust-proof, keeping off the rain.The outer end of middle swash plate 111 is outer panel 112, and outer panel 112 is turned over downwards Folding, can preferably play a part of keeping off the rain, and prevent rainwater from entering casing or interior.The inner of middle swash plate 111 is inner side Plate 113, interior plate 113 is flipped up and set in barb-shaped, can further play a part of dustproof and rainproof, also, worm Ant can also be blocked by barb, climb in not inlet body.

Described above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to Above-described embodiment, all technical schemes belonged under the utility model thinking belong to protection domain of the present utility model.It should refer to Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
