The two side faces of each side edge incline inwards from top to bottom, and the inclination angle c ranges from 2 degrees to 5 degrees. The screw decorative cover has the advantages that installation is easy, the edges of the screw decorative cover are directly pressed into the screw groove, the outer edges are slightly larger than the inner edges, and the outer edges deform in the pressing process so that the outer edges can be better attached to the screw groove.

Description

Technical Field

[0001] The utility model relates to a screw decorative cover. Background Art

[0002] At present, the current screw decorative covers are generally expensive and troublesome to install. Summary of the invention

[0003] The utility model aims to overcome the deficiencies of the prior art and provide a screw decorative cover which is easy to install by directly pressing the edges of the screw decorative cover into the screw groove. The outer edges are slightly larger than the inner edges. During the pressing process, the outer edges are deformed so as to better fit the screw groove.

[0004] In order to achieve the above object, the first technical solution of the utility model is implemented as follows, which is a screw decorative cover, characterized in that it includes:

[0005] A screw protrusion and a decorative cover; the upper part of the screw protrusion is installed on the lower part of the decorative cover, and the screw protrusion has two side ribs, three side ribs or four side ribs, and the side of each side rib is inclined inward from top to bottom and the inclination angle a is 20° to 23°, the two side surfaces of each side rib are inclined outward from inside to outside and the inclination angle β is 80° to 85°, and the two side surfaces of each side rib are inclined inward from top to bottom and the inclination angle c is 2° to 5°.

[0006] In the technical solution, guide slopes are provided on both sides of each side edge.

[0007] In the technical solution, the side edge of the decorative cover is provided with a curved surface.

[0008] Compared with the prior art, the utility model has the following advantages: simple installation, the edge of the screw decorative cover can be directly pressed into the screw groove, the outer edge is slightly larger than the inner edge, and the outer edge is deformed during the pressing process so as to better fit the screw groove.

[0014] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0015] like Figures 1 to 5 As shown, it is a screw decorative cover, comprising:

[0016] A screw protrusion 2 and a decorative cover 1; the upper part of the screw protrusion 2 is installed on the lower part of the decorative cover 1, and the screw protrusion 2 has two side ribs or three side ribs or four side ribs, and the side portion 22 of each side rib is inclined inward from top to bottom and the inclination angle a is 20° to 23°, such as 20° or 21° or 22° or 23°, and the two side surfaces 21 of each side rib are inclined outward from inside to outside and the inclination angle β is 80° to 85°, such as 80° or 81° or 82° or 83° or 84° or 85°, and the two side surfaces 21 of each side rib are inclined inward from top to bottom and the inclination angle c is 2° to 5°, such as 2° or 3° or 4° or 5°.

[0017] When in use, the user can directly press the screw protrusion 2 into the screw groove through the decorative cover 1. The screw protrusion 2 is made of plastic material by injection molding, which is low in cost and elastic. The two side surfaces 21 of each side ridge of the screw protrusion 2 are inclined outward from the inside to the outside so that the outer edge of the side ridge is slightly larger than the inner edge. During the pressing process, the outer edge is deformed so as to better fit the screw groove.

[0018] In this embodiment, guide slopes 221 are provided on both sides of each side rib side portion 22 .

[0019] In this embodiment, a curved surface 11 is disposed on the side of the decorative cover 1 .

[0020] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For ordinary technicians in this field, various changes, modifications, substitutions and deformations of these embodiments without departing from the principle and purpose of the present invention still fall within the scope of protection of the present invention.
