Description

Technical Field

[0001] This utility model relates to the field of floor drains, and in particular to a floor drain core diameter converter. Background Technology

[0002] Floor drains are an important interface connecting the drainage pipe system and the indoor floor. As an important component of the drainage system in a residence, their performance directly affects the quality of indoor air. To achieve the odor-proof function of floor drains, a floor drain core needs to be installed inside the floor drain.

[0003] For floor drains that do not have odor-proof functions, odor prevention can be achieved by installing a drain core later. However, the hole diameter of the drain outlet in the drain base is not uniform, and drain pipes with larger diameters are generally installed in floor drains with larger diameter outlets. This means that drain cores on the market cannot be adapted to floor drains with larger outlets, which causes a lot of trouble for users. Utility Model Content

Detailed Implementation

[0022] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] Example 1: As Figures 1-4 As shown, a drain core diameter converter includes a drain core 100 and a diameter-adjusting disc ring 200. The diameter-adjusting disc ring 200 has a mounting hole in its center for holding the drain core. The disc ring includes a collar 210. The collar 210 constitutes the diameter-adjusting disc ring, and its inner hole (i.e., the mounting hole) is adapted to the drain core. The collar is fitted inside the drain outlet of the drain base, realizing the diameter conversion installation of the drain core. This allows drain cores with smaller diameters to be adapted to drain bases with larger drain outlet diameters, improving the adaptability and versatility of drain core installation and bringing convenience to users. Different specifications of the collar can be selected.

[0025] In this embodiment, an annular groove A211 is provided at the upper end of the mounting hole of the variable diameter disc ring, and a convex ring A110 is provided on the outer edge of the upper end of the drain core for resting on the annular groove.

[0026] In this embodiment, a filter screen 300 is provided above the drain core 100. The depth of the annular recess A is greater than the height of the convex ring A to leave space above the drain core for placing the filter screen 300. The filter screen 300 is located in the annular recess A, and the annular recess A is used to limit the position of the filter screen 300.

[0027] In this embodiment, the mounting hole of the variable diameter disc ring 200 and the drain core are connected by threads. In actual implementation, the mounting hole of the variable diameter disc ring 200 and the drain core can also be connected by snap-fit ​​or tight fit.

[0028] The above-mentioned buckle connection method involves setting a buckle on the outer side of the drain core and setting a beveled or L-shaped groove on the inner wall of the installation hole. The buckle is aligned with the groove, inserted, and locked in the groove after rotating with the drain core.

[0029] The above-mentioned threaded connection method involves setting external threads on the outer periphery of the drain core and setting internal threads in the mounting hole.

[0030] The above-mentioned tight-fit connection method can be an interference fit, or it can be achieved by putting a silicone ring or rubber ring on the outside of the drain core, using the elasticity of the silicone ring or rubber ring to achieve tight fit and seal.

[0031] In this embodiment, the collar 210 includes an annular plate 212 and two annular surrounding plates 213 of different sizes with one large and one small on the lower side of the annular plate 212. The inner annular surrounding plate 213 forms the inner hole of the collar.

[0032] In this embodiment, a plurality of radially arranged ribs 214 are provided between the two annular surrounding plates 213.

[0033] Example 2: Figure 5 , 6 As shown, the variable diameter disc ring includes two concentrically nested collars 210, with one collar having a larger diameter than the other, forming the variable diameter disc ring. The inner collar fits into the inner hole of the outer collar. In specific implementations, the variable diameter disc ring can also be formed by three, four, five, six, or even more collars concentrically nested. By setting the collars in different sizes, a modular design is achieved. Depending on the diameter of the drain outlet of the floor drain base, the number and specifications of collars can be selected for individual use or assembly, making it convenient, flexible, and versatile. For example, there are four types of collars: collar 1 (inner diameter 40mm, outer diameter 60mm), collar 2 (inner diameter 60mm, outer diameter 80mm), collar 3 (inner diameter 80mm, outer diameter 100mm), and collar 4 (inner diameter 100mm, outer diameter 120mm). The outer diameter of the drain core is 40mm. If the diameter of the drain outlet of the drain base is 60mm, then only collar 1 needs to be used. If the diameter of the drain outlet of the drain base is 80mm, then only collar 1 and collar 2 need to be used together. If the diameter of the drain outlet of the drain base is 100mm, then only collar 1, collar 2, and collar 3 need to be used together.

[0034] In this embodiment, the two collars that fit together on the variable diameter disc ring are connected by a tight fit. In actual implementation, the two collars that fit together on the variable diameter disc ring can also be connected by a snap-fit ​​connection or a threaded connection.

[0035] The above-mentioned buckle connection method involves setting a buckle on the outer side of the inner ring collar and setting a beveled or L-shaped groove on the inner wall of the outer ring collar. The buckle is aligned with the groove, inserted, and locked in the groove after rotating with the inner ring collar.

[0036] The above-mentioned threaded connection method involves setting an external thread on the outer circumference of the inner ring collar and setting an internal thread on the inner side of the outer ring collar.

[0037] The above-mentioned tight-fit connection method can be an interference fit, or it can be achieved by putting a silicone ring or rubber ring on the outside of the inner ring collar, using the elasticity of the silicone ring or rubber ring to achieve tight fit and sealing. The tight-fit method is preferred because it is easier to install, has a simpler structure, and is easier to process.

[0038] In this embodiment, the two collars on the variable diameter disc ring are fitted together. The outer collar has an annular groove B215 at the upper end of the inner hole, and the inner collar has a protruding ring B216 at the upper outer periphery for resting on the annular groove B.
