Description

Technical Field

[0001] The utility model belongs to the field of stainless steel sinks, and particularly relates to components for enhancing the appearance of decorative sinks. Background Art

[0002] Before installation and use, during the stage from factory to sale, a stainless steel sink has one, two or three faucet tube through-holes. If not capped, it will affect the appearance, as the through-holes are dark and unsightly. Currently, the cap consists of two components, a base and a round cap. The base includes a hollow cylinder with internal threads and an outward flange at one end of the hollow cylinder. The round cap includes a cover plate and an externally threaded hollow cylinder under the cover plate. The base is located under the wall of the sink faucet tube hole, and the round cap is on the wall of the sink faucet tube hole. The externally threaded hollow cylinder of the round cap is screwed into the internally threaded hollow cylinder of the base so that the flange and the cover flange clamp the wall of the sink faucet tube hole to seal the hole. These components are generally made of plastic, with slow rotational installation efficiency, inconvenient disassembly and assembly, and are only used to block the hole, having a monotonous color and not looking high-class, for example, lacking colors like champagne gold or having the same visual effect as stainless steel. Summary of the Invention

[0003] The utility model provides a cap for a sink faucet tube hole, which solves the problems of inconvenient disassembly and assembly and slow efficiency of the existing cap, and at the same time provides more colors for enhancing the appearance. The technical solution is as follows:

[0004] The cap for a sink faucet tube hole includes a base and a round cap. The base includes a hollow cylinder and an outward flange at one end of the hollow cylinder; it also includes an annular cover buckle, and the base, the cover and the annular cover buckle are separate components; an inward flange is provided inside the hollow cylinder at one end of the hollow cylinder, and a round convex platform is provided upward on the top surface of the inward flange. A female buckle corresponding to the sub-buckle of the annular cover buckle is provided downward on the bottom surface of the flange outside the round convex platform, and a movable buckle protruding outward is provided on the wall of the hollow cylinder at the end far from the flange; the round cap includes a cover plate surface and a cover edge wrapping the round convex platform; the inner ring diameter of the annular cover buckle is smaller than the diameter of the round cap, and a cylindrical edge wrapping the round cap is provided downward on the bottom surface of the outer ring of the annular cover buckle. A sub-buckle corresponding to the female buckle is provided on the bottom surface of the annular cover buckle where the diameter is greater than the diameter of the round cap and smaller than the inner diameter of the cylindrical edge, and the annular cover buckle is buckled and pressed on the round cap; the movable buckle of the base and the flange clamp the wall of the sink faucet tube hole.

[0005] The round convex platform is a cylindrical convex platform, and the top surface of the cylindrical convex platform is closed. The round cap is such that the cover plate surface and the cover edge wrapping the cylindrical convex platform form a right angle; the annular cover buckle includes a top ring, a transition ring and a cylindrical edge wrapping the round cap. The top ring is slightly inclined, the transition ring is below the top ring, and the cylindrical edge wrapping the round cap is below the transition ring. A groove for pressing the round cap is provided on the bottom surface of the top ring.

[0006] The circular boss can be a conical boss or a cylindrical boss. Preferably, it is a cylindrical boss. The shape of the boss results in different shapes of the round cover. This round cover can be electroplated or coated with different colors using stainless steel material. During the coloring stage, the round covers corresponding to the conical bosses will stack up during the coloring process, resulting in inconsistent coloring and a large number of defective products. The round cover with the cover edge perpendicular to the cylindrical boss that encloses it cannot stack up and will disperse, greatly reducing the number of defective products with good color quality. The round cover in the shape of a conical boss is made into a brushed or frosted texture, which is consistent with the texture of the stainless steel sink. The circular ring of the annular cover buckle is perpendicular to the cylindrical edge, enabling it to buckle and cover the round cover. To facilitate smooth demolding, the top circular ring is slightly inclined. Below the top circular ring is a transition circular ring, and below the transition circular ring is the cylindrical edge that encloses the round cover.

[0007] Two of the described movable buckles are symmetrically arranged on the wall of the hollow cylinder. The female buckle is evenly provided with three through-hole female buckle columns, and the male buckle is evenly provided with three needle-shaped male buckles. The needle-shaped male buckles are inserted into the through-hole female buckle columns to tightly fasten. The male and female buckles can have other structures and shapes. For example, the male buckle can be designed to contract and expand.

[0008] The cover for the faucet hole of the sink includes a base and a round cover. The base includes a hollow cylinder and an outer flange extending outward from one end of the hollow cylinder; an outwardly protruding movable buckle is provided on the wall of the hollow cylinder at the end away from the flange; the round cover is made of stainless steel material, with a flat top surface. Below the flat top surface of the round cover is a transition inclined surface, and the outer edge of the transition inclined surface is folded inward to form a folded edge. The diameter of the folded edge is slightly smaller than the diameter of the outer flange, and the folded edge encloses the outer flange; the movable buckle of the base is stuck to the wall of the faucet hole of the sink with the outer flange. It is not convenient and fast to buckle the round cover with a right angle directly between the top of the round cover and the cover edge, that is, the stainless steel round cover is in the shape of a conical boss, and stacking will occur during coloring, resulting in inconsistent colors. Therefore, the stainless steel round cover of this shape is made into a brushed or frosted texture of stainless steel.

[0009] Advantages: The cover structure for the faucet hole of the sink with three parts and two parts integrated is reasonable, simple, and practical. Inserting and removing the movable buckle and clamping the wall of the faucet hole of the stainless steel sink with the outer flange is more convenient for disassembly and assembly and has higher efficiency. The stainless steel round cover can be colored, brushed, or frosted. The middle part, the round cover, of the three parts can have different colors. The round cover covers the cylindrical boss, the annular cover buckle presses and buckles the round cover, the male and female buckles are tightly combined, and it is quick to replace the round cover. It is also quick to replace between the cover with two parts integrated and the cover with three parts. The sealing and decoration look more diverse. Description of the Drawings
