Specifically: an aperture vane includes an aperture vane body in an arc-bending shape. The aperture vane body is a soft film. An upper end positioning post protruding upward is arranged on the upper surface of one end of the aperture vane body. A lower end positioning post protruding downward is arranged on the lower surface of the other end of the aperture vane body. The upper end positioning post and the lower end positioning post are respectively formed into an integral structure with the aperture vane body by insert injection molding.

[0003] It should be noted that for the above aperture vane, it has the following defects. Specifically: since there is no anti-loosening structure at the combination position of the vane body and the positioning post to increase the pulling force between the two, that is, the vane body and the positioning post are prone to looseness, so there is a defect of poor structural stability.

[0004] The purpose of the utility model is to provide a new aperture vane structure aiming at the deficiencies of the prior art. The new aperture vane structure has novel design, good structural stability and large pulling force and good strength.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions.

[0006] A new aperture vane structure includes a vane body and two spaced convex posts. Each convex post is a plastic part. One convex post is injection molded on the upper surface of the vane body, and the other convex post is injection molded on the lower surface of the vane body;

[0007] The vane body is respectively provided with main body through holes corresponding to the convex posts. Arch-shaped convex parts protruding towards the protruding sides of the corresponding convex posts are respectively arranged at the edge parts of the main body through holes;

[0008] Each convex post is respectively embedded into the corresponding main body through hole, and each arch-shaped convex part is respectively inserted into the interior of the corresponding convex post.

[0009] Among them, the arch-shaped convex part is in the shape of a cap body.

[0010] Among them, auxiliary through holes are arranged on the side wall of the arch-shaped convex part.

[0011] Among them, the vane body is a plastic part or a metal part.

[0012] Compared with the prior art, the utility model has the following beneficial effects. Specifically, during the injection molding process of the convex columns at the positions of the main body through holes of the blade main body, since each convex column is respectively filled and embedded into the corresponding main body through hole, and each arched convex part is respectively inserted into the inside of the corresponding convex column; the bonding structure between the blade main body and the convex column can effectively improve the pulling force between the two, thereby improving the stable reliability of their connection. Therefore, the novel aperture blade structure of the utility model has the advantages of novel design, good structural stability and reliability, and large pulling force and good strength.

[0023] The present utility model will be described below in conjunction with specific embodiments.

[0024] Embodiment 1, as Figures 1 to 4 shown, a novel aperture blade structure includes a blade main body 1 and two spaced convex columns 2. Each convex column 2 is a plastic part. One convex column 2 is injection molded on the upper surface of the blade main body 1, and the other convex column 2 is injection molded on the lower surface of the blade main body 1.

[0025] It should be explained that the blade body 1 of the first embodiment can be made of plastic material or metal material, that is, the blade body 1 of the first embodiment is a plastic part or a metal part.

[0026] Furthermore, as Figure 3 and Figure 4 shown, the blade body 1 is respectively provided with main body through holes 3 corresponding to the convex columns 2, and arched convex parts 4 that arch towards the protruding sides of the corresponding convex columns 2 are respectively arranged at the edge parts of the main body through holes 3.

[0027] Furthermore, each convex column 2 is respectively embedded into the corresponding main body through hole 3, and each arched convex part 4 is respectively inserted into the interior of the corresponding convex column 2.

[0028] It should be noted that, as Figure 3 and Figure 4 shown, the arched convex part 4 is in the shape of a cap body; specifically, the diameter value of the arched convex part 4 gradually increases from the end to the root.

[0029] It should be emphasized that during the process of injection molding the convex columns 2 at the positions of the main body through holes 3 of the blade body 1, since each convex column 2 is respectively filled and embedded into the corresponding main body through hole 3, and each arched convex part 4 is respectively inserted into the interior of the corresponding convex column 2; the above-mentioned combined structure between the blade body 1 and the convex column 2 can effectively improve the pulling force between the two, thereby improving the stable reliability of their connection.

[0030] Based on the above situation, through the above structural design, the new aperture blade structure of the first embodiment has the advantages of novel design, good structural stability and reliability, and large pulling force and good strength.

[0031] Embodiment 2, as Figure 5 shown, the difference between the second embodiment and the first embodiment is that: auxiliary through holes 5 are provided on the side wall of the arched convex part 4.

[0032] For the auxiliary through hole 5 structure of the second embodiment, when each convex column 2 is injection molded at the positions of the main body through holes 3 of the blade body 1, each convex column 2 will be filled into the auxiliary through hole 5, that is, each auxiliary through hole 5 will form a reverse buckle structure, thereby further increasing the stable reliability of the connection between the blade body 1 and the convex column 2, and further improving the pulling force between the blade body 1 and the convex column 2.

[0033] Embodiment 3, as Figure 6 shown, the difference between the third embodiment and the first embodiment is that: the arched convex part 4 is a flanging structure arranged at the edge position of the main body through hole 3.

[0034] The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, based on the idea of the present utility model, there will be changes in the specific implementation manners and application scopes.
