Floor drain assembly

Abstract

The floor drain assembly comprises a waterproof seat, a floor drain, and a telescopic connecting piece. The upper part of the telescopic connecting piece is fixed on the waterproof seat, and the lower part of the telescopic connecting piece is fixed on the main body of the floor drain. The flexible connection between the waterproof seat and the floor drain through the telescopic connecting piece realizes the waterproof integrated connection between the waterproof seat and the main body of the floor drain. Since the corrugated connecting piece can be telescopic, the height position of the floor drain can be freely changed, thereby ensuring the reliability of waterproof and the slope setting of pipeline drainage, and avoiding the influence of the floor drain on the waterproof performance when being stepped on.

Description

Technical Field

[0001] This invention relates to a floor drain, particularly a floor drain with good waterproof performance. Background Technology

[0002] Currently, leaks frequently occur between the waterproof base and the floor drain in prefabricated buildings. Because existing floor drains lack a flexible, integrated waterproof connection between the drain and the base, water above the waterproof layer flows down the outer wall of the drain to below the waterproof layer, causing indoor flooding. Therefore, there is an urgent need to develop a floor drain with improved waterproofing performance. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the above-mentioned defects of the prior art and provide a floor drain assembly with better waterproof performance.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0005] A floor drain assembly, characterized in that it includes a waterproof base, a floor drain, and a retractable connector, wherein the upper part of the retractable connector is fixed to the waterproof base, and the lower part of the retractable connector is fixed to the floor drain body.

[0006] More specifically, the waterproof base can be of various shapes, such as round or square, and may be called a waterproof plate or waterproof chassis, through which the entire floor drain assembly is installed onto the drain hole in the ground.

[0007] Even better, the retractable connector is a corrugated connector, which is easier to manufacture.

[0008] Even better, the upper end of the corrugated connector is provided with an upper sealing element, which is fixed to the waterproof seat by an upper pressure ring.

[0009] Even better, the lower end of the corrugated connector is provided with a lower seal, which is fixed to the floor drain by a lower pressure ring.

[0010] Even better, the retractable connector is a corrugated connector, which is easier to manufacture.

[0011] The aforementioned upper seal, upper pressure ring, lower pressure ring, lower seal, and corrugated connector can be integrated as one unit or separate components. It is better to integrate them as one unit, as this facilitates manufacturing.

[0012] Compared with the prior art, the advantages of the present invention are as follows: the flexible connection between the waterproof base and the floor drain through the telescopic connector realizes the integrated waterproof connection between the waterproof chassis and the floor drain body. At the same time, since the corrugated connector can extend and retract, the height of the floor drain can be freely adjusted, thereby ensuring not only the reliability of waterproofing, but also the slope setting of the drainage pipe, and preventing the floor drain from being affected by being stepped on. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of the floor drain assembly according to an embodiment of the present invention.

[0014] Figure 2 for Figure 1 Enlarged cross-sectional view of part A in the image. Detailed Implementation

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 As shown, the floor drain assembly includes a waterproof base 1, a corrugated connector 4, and a floor drain body 2. The waterproof base 1 is connected to the floor drain body 2 through the corrugated connector 4. The waterproof base 1, the floor drain body 2, and the corrugated connector 4 form an integral whole, so that water on the waterproof base 1 will not leak through the gap between it and the floor drain 2 to the side and below of the floor drain 2.

[0017] like Figure 2 As shown, the upper pressure ring 7 presses the upper sealing ring 5 at the upper end of the corrugated connector 4 onto the waterproof chassis 1 by screws 6.

[0018] like Figure 2 As shown, the lower pressure ring 9 presses the lower sealing ring 10 at the lower end of the flexible corrugated connector 4 onto the sealing surface 11 of the drain body 2 through the screw 8.

[0019] like Figure 2 As shown, there is an upper sealing ring 5 between the waterproof base 1 and the connecting component 4, and a lower sealing ring 10 between the drain body 2 and the connecting component 4, thus creating a seal between the drain body and the waterproof base 1.

[0020] like Figure 2 As shown, when the distance between the drain body 2 and the waterproof base 1 changes, the crest point 15 and trough point 13 of the corrugated structure can deform, and the angle of the wall 14 between the crest and trough of the corrugation also changes, so as to adapt to the change in the distance between the drain 2 and the waterproof base 1.

[0021] The aforementioned corrugated connector 4 should have at least one corrugation to ensure that the distance between the corrugated connectors can be varied.

[0022] The area between the peak point 15 and the trough point 13 can be a triangle, an arc, or a trapezoid.

Claims

1. A floor drain assembly, characterized in that: The system includes a waterproof base, a floor drain, and a flexible corrugated connector. The upper part of the flexible corrugated connector is fixed to the waterproof base, and the lower part is fixed to the floor drain body. An upper sealing ring is provided at the upper end of the flexible corrugated connector, which is fixed to the waterproof base by an upper pressure ring. A lower sealing ring is provided at the lower end of the flexible corrugated connector, which is fixed to the floor drain by a lower pressure ring. The upper sealing ring, upper pressure ring, lower pressure ring, lower sealing ring, and flexible corrugated connector are integrated into one unit. The upper pressure ring presses the upper sealing ring of the flexible corrugated connector firmly onto the waterproof base with screws, and the lower pressure ring presses the lower sealing ring of the flexible corrugated connector firmly onto the sealing surface of the floor drain body with screws.
