Description

Technical Field

[0001] The utility model relates to the field of sanitary ware accessories, in particular to a toilet water outlet sealing ring. Background Art

[0002] When installing a toilet, it is necessary to connect the toilet drain outlet to the sewer pipe reserved on the ground. At this time, a water outlet sealing ring, also called a water outlet flange pipe, is needed. Its function is to connect the toilet drain outlet and the sewer pipe and keep it sealed. As we all know, in order to ensure the sealing, it is necessary to apply glue on the top surface of the water outlet sealing ring to enhance its sealing with the toilet drain outlet, and to cover the lower part of the water outlet sealing ring with a rubber sealing gasket to enhance the sealing between it and the ground drain outlet. However, the top surface of the existing water outlet sealing ring lacks a glue retention structure, and the applied glue is easy to touch and shift when the toilet is plugged in, causing sealing defects; in addition, the existing water outlet sealing ring also lacks a limiting structure for the rubber sealing gasket, and the rubber sealing gasket is also easy to shift under force when plugged into the sewer pipe reserved on the ground, causing sealing defects; therefore, a toilet water outlet sealing ring that can effectively solve the above problems is proposed herein. Utility Model Content

[0003] In view of the problems existing in the background technology, the purpose of the present utility model is to provide a toilet water outlet sealing ring, which effectively solves the problems existing in the background technology.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The toilet water outlet sealing ring includes an integrally connected upper section, a middle tapered section and a lower section. The top surface of the upper section is integrally provided with a ring edge, and a plurality of ring edges are coaxially provided on the ring edge; the lower section is integrally provided with an upper and a lower limiting ring edge, and a gasket is detachably installed on the lower section between the upper and lower limiting ring edges, and the outer diameter of the gasket is larger than the outer diameter of the limiting ring edge.

[0006] Furthermore, the height of the ring edge is 0.5mm-1mm.

[0007] Furthermore, the number of the ring edges is three, and the spacing between adjacent ring edges is 2mm-3mm.

[0008] Furthermore, the gasket includes a base ring and multiple extension rings integrally arranged on the base ring. The multiple extension rings are evenly distributed in the vertical direction and the outer diameter of the extension ring is larger than the outer diameter of the limiting ring edge. The uppermost extension ring is pressed against the upper limiting ring edge, and the lowermost extension ring is pressed against the lower limiting ring edge.

[0009] Furthermore, there are three extension rings, wherein the outer diameter of the lowest extension ring is smaller than the outer diameters of the remaining two extension rings.

[0010] Furthermore, the upper section, the middle tapered section and the lower section are all made of PVC.

[0011] Furthermore, the gasket is made of rubber.

[0012] The utility model has the following beneficial technical effects:

[0013] The top surface ring edge of the upper section in the utility model is coaxially provided with multiple ring edges, which can effectively increase the adhesion when applying glue, so that the applied glue can be maintained in the predetermined working position, avoiding easy contact and displacement when inserted into the toilet drain outlet, thereby causing sealing defects; in addition, the gasket in the present application has limit ring edges fixed on the lower section at the top and bottom, which can effectively avoid displacement when inserted into the drain outlet reserved on the ground, thereby ensuring the normal working position and sealing effect of the gasket.

[0016] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0017] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "upper", "lower", "left", "right", "inside", "outside", "front end", "rear end", "head", "tail", etc. indicate directions or positional relationships 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, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] like Figure 1 and Figure 2As shown, the toilet water outlet sealing ring described in this embodiment includes an upper section 1, a middle tapered section 2 and a lower section 3 that are integrally connected.
