Detailed Description

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

The present case relates to a practical floor drain, as shown in fig. 1-6, comprising a face seat 1 and a floor drain core 2, wherein the face seat 1 is installed on an installation hole on the ground, and the floor drain core 2 can be disassembled and assembled in the face seat 1 and correspondingly extends into a downcomer 500 below the face seat 1.

The floor drain core 2 comprises a core body 21 and a sealing cover plate 22. The sealing cover plate 22 is movably installed at the water outlet of the core body 21. The upper end of the sealing cover 22 is protruded with a weight block 221, so as to seal by using the gravity eccentricity principle. The water-tight design principle of the floor drain core 2 is the conventional technology of the existing eccentric block type floor drain, the structure of the sealing cover plate 22 and the matching structure of the sealing cover plate and the water outlet can be designed into various structures, such as a horizontal type, a vertical type, an inclined type and the like, which are all the existing conventional designs, and the core design point of the scheme is that the defects of the existing eccentric block type floor drain are improved.

Face seat 1 has from last panel portion 11, the appearance chamber portion 12 and nested portion 13 of undergauge design down, and panel portion 11 is used for inlaying and puts on the ground installing port, and appearance chamber portion 12 does benefit to installation floor drain core 2, has certain water of depositing simultaneously, does benefit to offal drainage effect. The nesting part 13 is mainly used for limiting and installing the floor drain core 2.

Correspondingly, the core body 21 is provided with a limiting part 211, a nesting section 212 and a protruding section 213 from top to bottom, and the protruding section 213 is provided with a drainage port 2131 of the floor drain core 2. Spacing in nested portion 13 top of the spacing portion 211 realizes locating the installation in face seat 1. The embedding section 212 is correspondingly arranged in a matching and embedding manner with the embedding part 13 inside and outside, in order to improve the sealing performance between the floor drain core 2 and the face seat 1, a sealing ring 23 is arranged on the outer side wall of the embedding section 212, and the sealing ring 23 realizes the sealing effect between the embedding section 212 and the embedding part 13. After the floor drain core 2 is installed, the extension section 213 of the floor drain core extends out of the nesting part 13 of the face seat 1, and the diameter value of the extension section 213 is smaller than that of the nesting section 13, so that the floor drain core 2 can be easily, freely and flexibly placed in the face seat 1 and taken out of the face seat 1.

The core technical scheme of the scheme is that an occupying convex structure 2132 is arranged right above a corresponding balancing weight 221 on the extending section 213, and the occupying convex structure 2132 is arranged on the outer side wall of the embedding section 212 in the radial direction of the extending section 213. Therefore, on the premise of not influencing the simple assembly of the floor drain core 2, in the operation of placing the floor drain core 2, no matter whether the offset defect exists in the installation between the face seat 1 and the sewer pipe 500, by means of the space occupation of the occupying convex structure 2132 on the extending section 213, after the floor drain core 2 is placed and installed in place, the enough space is always reserved between the sealing cover plate 22 (particularly the balancing weight 221 thereof) and the inner side wall of the sewer pipe 500 for the free movement of the sealing cover plate 22, and therefore the problem that the floor drain sealing cover plate 22 hits the inner side wall of the sewer pipe is completely avoided.

For example, a relatively large deviation exists between the face lifting seat 1 and the downcomer 500, as shown in fig. 5, one side of the downcomer 500, which corresponds to the face seat 1, is a deviation side (right side in fig. 5), and due to the space occupation of the occupation convex structure 2132, a certain arc-shaped limiting area (shown in fig. 5 as a situation that the floor drain core 2 can be just placed in the face seat 1) exists in the position of the inner side wall where the downcomer 500 corresponds to the deviation side. Of course, the existence or non-existence of the arc-shaped limiting area and the size of the area are determined by the mutual position relation of the installation between the face seat 1 and the downcomer 500.

At this moment, the floor drain core 2 is rotated properly, so that the occupied convex structure 2132 staggers the arc-shaped limiting area, and the floor drain core 2 can be assembled in an embedded mode. In other words, as long as the floor drain core 2 is assembled on the face seat 1, it is ensured that the sealing cover plate 22 is spaced apart from the inner side wall of the downcomer 500 enough for the sealing cover plate 22 to move freely. When the floor drain core 2 can not be assembled in the face seat 1, the occupied convex structure 2132 is not staggered in the arc limiting area, and the floor drain core 2 only needs to be rotated properly to realize staggering, so that the assembly can be completed.

Preferably, the protruding structure 2132 is disposed circumferentially on the protruding section 213 to cover at least the upward span (i.e., the horizontal transverse span in fig. 4) of the weight block 221. Therefore, the sealing cover plate 22 can be assembled in the arc-shaped limiting area in a staggered mode, and the free movement effect of the sealing cover plate 22 is finally guaranteed.

Preferably, the occupying convex structure 2132 is a plurality of occupying convex teeth, the plurality of occupying convex teeth are arranged along the outer side wall of the protruding section 213, and two outermost convex teeth of the plurality of occupying convex teeth are correspondingly arranged at positions outside two ends of the weight block 221 in the corresponding upward direction (see fig. 4). Here, the space-occupying convex structure 2132 is disposed circumferentially on the protruding section 213 to cover at least the span of the weight block 221 in the corresponding upward direction.

Preferably, the weight block 221 is an arc convex pillar, and both ends of the arc convex pillar and a connection part with the sealing cover plate 22 are rounded smooth curved surface structures. This ensures that the sealing cover as a whole, in particular the projections on the rear side of the sealing cover 22 which are close to rotation, are not formed as areas which are prone to dirt and dirt becoming entangled, and this further ensures the functional function of the sealing cover 22.

Preferably, a sealing gasket 24 is arranged on the inner plate surface of the sealing cover plate 22, and the sealing gasket 24 is adapted to the water outlet 2131 of the floor drain core 2.

The upper end of the floor drain core 2 is provided with a lifting rib plate 214 for facilitating the lifting and assembling of the floor drain core 2.

The floor drain also comprises a surface filtering cover 3, and the surface filtering cover 3 is covered on the surface base 1 to play a role in primary filtering and anti-blocking on the surface of the floor drain. Moreover, the floor drain also comprises a filter element 4, and the filter element 4 is arranged in the upper position of the surface seat 1 corresponding to the floor drain core 2 and plays a role in preventing the secondary filtering and the blockage in the floor drain.

The foregoing is only a preferred embodiment of the present invention and all equivalent changes and modifications made within the scope of the present invention are intended to be covered by the appended claims.
