The utility model discloses a pinhole assembly micro-interference structure, which comprises a mounting plate 1 and at least one pinhole 2 arranged on the mounting plate 1 and used for assembling jacks; the side wall of the pinhole 2 is provided with a convex structure.
The pinhole 2 on the mounting plate can adopt various structures, such as the structures shown in fig. 1, 2 and 5, namely, the mounting plate comprises two coaxially arranged pinhole segments, the diameters of the two pinhole segments are different, and the bulge structure is arranged on the inner side wall of the pinhole segment with larger diameter. Of course, when the pinhole is adopted, the convex structure can be arranged on the inner side wall of the pinhole section with smaller diameter at the same time or only, and fig. 1, 2 and 5 are only examples and are not limiting on the arrangement positions.
In particular, the bump structure may be implemented in a variety of structures.
As shown in fig. 1, 2, 3 and 4, the protruding structures are strip-shaped, and the axes of the protruding structures are arranged in parallel with the axes of the pinholes 2. Specifically, the inner side surface of the strip-shaped protruding structure can be an arc surface or be formed by two intersecting planes. The inner side surface here refers to a portion of the protrusion structure disposed in the pinhole 2, and the stripe-shaped protrusion structure shown in fig. 1, 2, 3, and 4 is formed by two intersecting planes.
When the protruding structures of the structure are adopted, at least 2 protruding structures are adopted, and more protruding structures, such as 3 protruding structures, 4 protruding structures, 5 protruding structures and the like, can be arranged. Preferably, the protruding structures are uniformly distributed around the inner wall of the pinhole 2. In order to simplify the structure and facilitate processing, when the convex structures of the structure are adopted, as shown in fig. 1, the number of the convex structures is 3.
By adopting the structure, when assembling is performed, the jack is directly assembled into the pinhole in a micro interference manner through three edges of the protruding structure.
Illustratively, as shown in FIG. 5, the raised structures are hemispherical. When hemispherical convex structures are adopted, the same is true, and at least two convex structures exist. Preferably, the protruding structures are uniformly distributed around the inner wall of the pinhole 2.
When hemispherical convex structures are adopted, the arrangement mode of the convex structures can be in various forms. For example, as shown in fig. 5, at least two rows of protruding structures are arranged along the axial direction of the pinhole 2, that is, the connection line of the vertices of each row of protruding structures forms an edge, and the connection line of the vertices of at least two rows of protruding structures forms at least two edges, where the vertices refer to the point where the hemispherical protruding structures are closest to the pinhole diameter. The micro interference assembly principle of the structure and the jack is similar to that of a strip-shaped convex structure. For another example, the plurality of protruding structures are respectively arranged on the same diameter surface of the side wall of the pinhole 2, that is, the top points of the protruding structures on the same diameter surface are in micro interference fit with the jacks.
By adopting any protruding structure, micro interference assembly can be carried out through the edges or points of the protruding structure and the insertion holes, so that the processing precision requirement on pinhole parts is low on one hand, and the interference force is small, so that the assembly is facilitated; meanwhile, the small-spacing jack interference assembly can be met, the rapid, reliable and low-cost assembly is realized, and the device has the advantages of being small in size, light in weight, high in reliability, low in cost, high in assembly efficiency, wide in application range and the like.
In conclusion, the structure has the advantages of low cost, high assembly efficiency, wide application range and the like.
Although the present utility model has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present utility model.
