Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and in particular to an overflow component and a drainage device. Background Technology

[0002] Current bathtub overflow structures generally use threaded fastening connections, as shown in patent publication CN218027985U. This involves a fixing screw penetrating the bathtub wall, which, along with a locking nut, connects the lid to the seat. This method has significant drawbacks. It requires simultaneous operation from both the inside and outside of the bathtub body: tightening the fixing screw on the inside and tightening the locking nut on the outside. For users who need to replace the lid, each time the nut needs to be unscrewed and repositioned, the entire lid needs to be replaced, undoubtedly increasing costs and resulting in low assembly efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide an overflow component and a drainage device.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an overflow component, comprising an overflow panel and an overflow connector respectively disposed on the inner and outer sides of the bathtub body. The overflow panel has an overflow hole, and an overflow channel is formed between the overflow panel and the overflow connector. A connector is provided on the side of the overflow panel facing the overflow connector, and a slot adapted to the shape of the connector is provided on the overflow connector. The connector engages with the slot. The overflow panel has an overflow connecting seat that can extend into the overflow connector. The open end of the overflow connecting seat communicates with the overflow hole of the overflow panel, and the other end of the overflow connecting seat has a drain hole. When the overflow panel and the overflow connector are aligned and installed, the connector is inserted into the slot to guide axial alignment, thereby forming a fluid passage between the overflow panel and the overflow connecting seat.

[0005] As a preferred embodiment of this utility model, two plug-in components are provided and symmetrically arranged on both sides of the overflow connector.

[0006] As a preferred embodiment of this utility model, the connector includes a plurality of spring pieces spaced apart along the circumferential direction. After the connector is inserted into the slot, the spring pieces are compressed and retracted to reset, thereby realizing the connection between the overflow panel and the overflow connector.

[0007] As a preferred technical solution of this utility model, the overflow panel is symmetrically provided with two connecting posts on the side facing the overflow connector; the number of plug-in parts is two, and each plug-in part is threadedly connected to the corresponding connecting post.

[0008] As a preferred embodiment of this utility model, the connecting column is provided with an external thread, and the plug-in is provided with an internal thread hole that mates with the external thread.

[0009] As a preferred technical solution of this utility model, the overflow connector is provided with positioning holes on both sides corresponding to the connecting column, and the connecting column of the overflow connector is aligned with the positioning holes of the overflow connector.

[0010] As a preferred technical solution of this utility model, it also includes a fixing plate, which is disposed on the inner wall of the bathtub body and has multiple mounting holes; the fixing plate is fixedly connected to the overflow connector by screws passing through the mounting holes.

[0011] As a preferred embodiment of this utility model, the overflow connector is provided with a sealing gasket on the side facing the overflow panel.

[0012] A drainage device includes an overflow assembly for installation on the side wall of a bathtub body, a drain for installation on the bottom of the bathtub body, and a drain pipe connecting the two.

[0013] As a preferred embodiment of this utility model, the drainer is provided with a flat pipe connector for connecting a drain pipe, wherein the drain pipe is a flat pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The spring clips of the connectors are press-fitted into the inner wall of the slots. During installation, axial alignment and locking are completed by simply inserting the connectors, replacing traditional threaded fasteners. During disassembly, the connectors can be separated with the help of external force, making replacement and maintenance convenient.

[0016] The overflow connector is pre-positioned with the connecting column through the positioning hole to achieve initial alignment during installation. The symmetrically arranged plug-in parts are threaded with the connecting column to achieve compression and fixation, replacing the traditional welding / gluing. The overflow connector and overflow panel can be detachably connected. This modular design facilitates the replacement of parts and reduces maintenance costs. The "plug-in pre-positioning and symmetrical compression" dual mechanism solves the defect of traditional overflow chambers that cannot be disassembled. Attached Figure Description

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0026] like Figures 1 to 6 The diagram illustrates an overflow assembly and a drainage device. The overflow assembly includes an overflow panel 1 and an overflow connector 2 respectively disposed on the inner and outer sides of the bathtub body. The overflow panel 1 has an overflow hole 3, forming an overflow channel between the overflow panel 1 and the overflow connector 2. A connector 4 is provided on the side of the overflow panel 1 facing the overflow connector 2, and the overflow connector 2 has a slot 5 that matches the shape of the connector 4, with the connector 4 engaging with the slot 5. The overflow panel 1 also has an overflow connection seat 6 that can extend into the overflow connector 2, with an opening in the overflow connection seat 6. The overflow panel 1 is connected to the overflow hole 3 at one end, and the overflow connector 6 is provided with a drain hole 7 at the other end. When the overflow panel 1 and the overflow connector 2 are aligned and installed, the plug 4 is inserted into the slot 5 to guide axial alignment, so that a fluid passage is formed between the overflow panel 1 and the overflow connector 6. In this embodiment, the overflow component is part of the drainage device, which is mainly used in the bathtub body. The main improvement of this application is the detachable structure of the overflow panel 1 and the overflow connector 2 in the overflow component. Therefore, the principle of other parts is not described.

[0027] The spring 9 of the connector 4 is interference-fitted with the inner wall of the slot 5. During installation, the axial alignment and locking are completed by aligning and inserting the connector, which replaces the traditional threaded fastening. During disassembly, it can be separated with the help of external force, which is convenient for replacement and maintenance.

[0028] Two connectors 4 are provided and symmetrically arranged on both sides of the overflow connector 6. The connector 4 includes multiple spring pieces 9 distributed at intervals along the circumferential direction. After the connector 4 is inserted into the slot 5, the spring pieces 9 are pressed inward and reset to achieve the connection between the overflow panel 1 and the overflow connector 2.

[0029] Two connecting posts 10 are symmetrically provided on the side of the overflow panel 1 facing the overflow connector 2; there are two plug-in parts 4, and each plug-in part 4 is threadedly connected to the corresponding connecting post 10.
