[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0021] like Figures 1 to 4As shown, this embodiment discloses a hidden decorative structure, including a part to be fixed 1, a screw 2, a buckle cap base 3, a threaded sleeve 4 and a decorative buckle cap 5. A sink 11 is provided on the surface of the part to be fixed 1, and the buckle cap base 3, the threaded sleeve 4 and the decorative buckle cap 5 are accommodated in the sink 11. The edge of the sink 11 and the surface of the part to be fixed 1 are transitioned by a rounded corner 12. A through hole 6 is provided on the bottom surface of the sink 11, and a through hole 6 is provided on the buckle cap base 3. The screw 2 passes through the buckle cap base 3 and the through hole 6 on the part to be fixed 1 in turn to fix the part to be fixed 1 on other objects. The buckle cap base 3 and the threaded sleeve 4 are connected by threads, and the threaded sleeve 4 and the decorative buckle cap 5 are interference fit. The decorative buckle cap 5 is tightly pressed against the outside of the threaded sleeve 4 along the axial direction of the screw 2, and the depth of the decorative buckle cap 5 installed in the sink 11 is adjustable. When the surface of the decorative buckle cap 5 is flush with the surface of the part to be fixed 1, the brim 51 of the decorative buckle cap 5 is in seamless contact with the rounded corner 12 to eliminate the gap between the brim 51 and the part to be fixed 1. The height of the decorative buckle cap 5 in the sink 11 is adjustable, and the decorative cap is designed with a large brim 51, which can cover the sink 11 and weaken the installation position of the screw 2 of the fixed part 1 to achieve a beautifying effect.

[0022] The length of the decorative buckle cap 5 along the axial direction of the screw 2 (that is, the height of the decorative buckle cap 5) is not greater than the depth of the sink 11 (that is, the distance between the bottom surface of the sink 11 and the surface of the part 1 to be fixed), and the sum of the height of the decorative buckle cap 5 and the height of the threaded sleeve 4 is not less than the distance between the bottom surface of the sink 11 and the surface of the part 1 to be fixed. The depth of the decorative buckle cap 5 buckled on the threaded sleeve 4 is adjustable, that is, the depth of the decorative buckle cap 5 pressed into the sink 11 can be adaptively adjusted. Even if the depth of the sink 11 is deepened, the decorative buckle cap 5 can be buckled on the threaded sleeve 4, and the decorative buckle cap 5 can still keep its surface flush with the surface of the part 1 to be fixed. The brim 51 of the decorative buckle cap 5 is matched with the fillet 12 to eliminate the gap between the brim 51 and the part 1 to be fixed. The decorative buckle cap 5 and the threaded sleeve 4 are hole-axis matched. The decorative buckle cap 5 can be removed from the threaded sleeve 4 by slowly rotating it.

[0023] In a specific structure, the outer peripheral surface of the buckle cap base 3 is provided with an external thread, the inner hole wall of the threaded sleeve 4 is provided with an internal thread, and the threaded sleeve 4 is tightly screwed on the outside of the buckle cap base 3 through the cooperation of the internal thread and the external thread. In other embodiments, the connection method between the buckle cap base 3 and the threaded cap is not limited to this. For example, a groove with an internal thread can also be provided on the buckle cap base 3, and an external thread can be provided on the outside of the threaded sleeve 4, and the threaded sleeve 4 can be screwed into the groove.

[0024] The fixed part 1 includes but is not limited to machined metal parts, sheet metal parts and plastic parts. The fixed part 1 can be a decorative panel on the inner roof of a bus. For the sake of aesthetics, this decorative structure can be used on parts that require the installation of screws 2.

[0025] The brim 51 of the decorative buckle cap 5 matches the opening of the sink 11, and the sink 11 is mostly circular, so the decorative buckle cap 5 is also set to be circular. If the sink 11 is set to a shape other than a circle, the decorative buckle cap 5 is also adapted to change.

[0026] The decorative buckle cap 5 includes a top plate 52 and an annular wall 53 connected to the top plate 52 on one side close to the buckle cap base 3, one end of the inner hole of the annular wall 53 is closed by the top plate 52, and the other end is provided with an opening, the annular wall 53 is arranged on the outside of the threaded sleeve 4 through an interference fit, and the side of the top plate 52 facing away from the annular wall is flush with the surface of the part to be fixed 1, and the top plate 52 extends around to form a brim 51, and the brim 51 cooperates with the rounded corner 12 on the part to be fixed 1 to avoid a gap between the brim 51 of the decorative buckle cap 5 and the part to be fixed 1.

[0027] The threaded sleeve 4 and the buckle cap base 3 can be made of metal materials, such as aluminum, iron, stainless steel and brass. Iron parts need to be surface treated to prevent rust, such as chrome plating or painting, which will produce harmful substances on the surface, which is not conducive to green environmental protection. In this embodiment, preferably, the decorative buckle cap 5 and the buckle cap base 3 are made of brass, which can meet the strength requirements, prevent rust, do not require electroplating, and contain no harmful substances.

[0028] The middle part of the buckle cap base 3 near the decorative buckle cap 5 is concave to form a groove 31, and the through hole 6 for the screw 2 to pass through is arranged at the bottom of the groove 31. By providing the groove 31, the weight of the buckle cap base 3 is reduced and the material of the buckle cap base 3 is saved, while the overall thickness of the buckle cap base 3 is not reduced, that is, the number of turns of the external thread on the buckle cap base 3 is not reduced.

[0029] As described above, the embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model. Therefore, all other embodiments obtained by ordinary technicians in the field without making creative work belong to the protection scope of the utility model.
