Description

Technical Field

[0001] The invention relates to the field of building drainage, in particular to a cover plate used for adjusting the installation position of a floor drain. Background Art

[0002] The floor drain is an important device that connects the ground and the drainage pipe.

[0003] The installation position of the floor drain is restricted by the layout of the drainage pipes and is not easy to adjust. Especially when the drainage pipes are concealed, the fixed position of the drainage interface reserved in the drainage pipes further increases the difficulty of adjusting the installation position of the floor drain. The laying of floor tiles requires complicated calculations and the installation position of the floor drain to avoid excessive cutting and splicing of tiles. The operation is inefficient and has little effect. In particular, when the floor drain is a long strip structure and needs to be accurately installed in a designated position according to special requirements, such as being symmetrically installed at the edge of the shower area, the correct installation of the floor drain and the aesthetics of the transition interface between the floor drain and the floor tiles cannot be guaranteed.

[0004] For designers, construction workers or owners, adjusting the installation position of floor drains is a difficult problem that needs to be solved urgently. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a cover plate for adjusting the installation position of a floor drain, which can adjust the installation position of the floor drain in the horizontal direction, thereby ensuring the correct installation and operation efficiency of the floor drain, as well as the aesthetics of the transition interface between the floor drain and the floor tiles; the cover plate described in the present invention has a simple and compact structure, is easy to implement and use, has high adjustment efficiency, and effectively prevents odor leakage in the drainage pipe.

[0008] The cover plate adopts the above structure, and the cover plate body is used to detachably cover the vertical drainage interface. The position of the eccentric through hole can be adjusted by rotating the cover plate body, and the position of the floor drain access through hole can be adjusted by rotating the cover plate split. It is easy to use and the adjustment is convenient and intuitive; the above double eccentric rotation ensures the flexibility of adjusting the position of the floor drain access through hole.

[0009] In the cover plate for adjusting the installation position of a floor drain as described above, the eccentric through hole is arranged on the axis of the vertical circle, which is conducive to expanding the adjustment range of the eccentric through hole and ensuring that its adjustment range includes the position where the axis of the vertical circle is located.

[0010] In the cover plate for adjusting the installation position of a floor drain as described above, the diameter of the eccentric through hole is not less than the radius of the vertical circle, which is conducive to further expanding the adjustment range of the eccentric through hole and improving the utilization rate of the limited size space to ensure the compactness of the overall structure.

[0011] The cover plate for adjusting the installation position of the floor drain as described above has a baffle cover on the upper cover of the floor drain access hole to prevent debris from falling into the drainage interface and causing clogging of the drainage pipe, which is conducive to use in complex work sites in decoration projects and ensures safety of use.

[0027] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which are intended to be used to explain the present invention but should not be construed as limiting the present invention.

[0028] A cover plate for adjusting the installation position of a floor drain comprises a cover plate body 1, wherein the cover plate body 1 is vertically provided with a circular eccentric through hole 11 deviating from the axis of a vertical circle at a position not exceeding the radial range of the vertical circle, the eccentric through hole 11 is covered with a cover plate split 2 rotatable around the axis of the eccentric through hole 11, the cover plate split 2 is vertically provided with a floor drain access through hole 21 for connecting a drain outlet of the floor drain at a position not exceeding the radial range of the eccentric through hole 11, and the floor drain access through hole 21 deviates from the axis of the eccentric through hole 11.

[0029] The cover plate of the present invention is as follows Figure 1 As shown, the structure is simple and easy to implement. It is used for transition connection of the drain outlet of the floor drain and the vertical drainage interface. The cover plate body 1 can be detachably covered on the drainage interface of matching size to ensure that the vertical circle described in the present invention does not exceed the range of the drainage interface (that is, to ensure that the floor drain access hole 21 always passes through the drainage interface). Generally, the drainage interface is circular. The present invention realizes the (horizontal) adjustment of the floor drain installation position by adjusting the (horizontal) position of the floor drain access hole 21. The adjustment principle is as follows: the position of the eccentric through hole 11 (floor drain access hole 21) can be adjusted by rotating the cover plate body 1 (on the drainage interface), and the position of the floor drain access hole 21 can be adjusted by rotating the cover plate split 2 (on the eccentric through hole 11), that is, the horizontal position of the floor drain access hole 21 can be adjusted by the above-mentioned at least one eccentric rotation. The principle is simple, efficient and intuitive, and the double eccentric rotation ensures the flexibility of the adjustment operation.

[0030] In order to expand the adjustment range of the eccentric through hole 11, the eccentric through hole 11 is arranged on the axis of the vertical circle, such as Figure 2 As shown, the axis of the vertical circle (the axis of the vertical circle is parallel to the axis of the eccentric through hole 11) passes through the eccentric through hole 11 (that is, the adjustment range of the eccentric through hole 11 includes the position of the axis (center) of the vertical circle). By expanding the adjustment range of the eccentric through hole 11, the adjustment range of the floor drain access hole 21 is further expanded.

[0031] To ensure the adjustment range of the eccentric through hole 11, the diameter of the eccentric through hole 11 is not less than the radius of the vertical circle. To facilitate the compactness of the overall structure (making full use of the space within the vertical circle), preferably, Figure 5 As shown, the diameter D of the eccentric through hole 11 is greater than the radius R of the vertical circle.

[0032] To ensure that the present invention is applicable to complex work sites in decoration engineering, such as Figure 1 and Figure 2 As shown, a baffle cover 3 is provided on the upper cover of the floor drain access hole 21 to prevent debris from falling into the drainage pipe from the floor drain access hole 21 and causing blockage; to facilitate installation and disassembly operations (when the drain outlet of the floor drain is connected, the baffle cover 3 needs to be removed), preferably, a handle portion 32 is provided on the top of the baffle cover 3.

[0033] To ensure the efficiency of the adjustment operation of the present invention, Figure 5 and Figure 6As shown, a first positioning mark 31 for locating the drain outlet of the floor drain is provided on the top surface (top) of the retaining cover 3. To facilitate the size measurement and the adjustment and positioning of the drain access through hole 21, the first positioning mark 31 indicates the installation position of the drain outlet of the floor drain, and it corresponds to the center or symmetry center or projection center of the drain outlet of the floor drain (in the installed state, the projection of the drain outlet of the floor drain on the horizontal plane is generally circular, or other shapes within a circular range, that is, the first positioning mark 31 is the center of the circle or the circular range).

[0034] In order to ensure the adjustment range of the floor drain access through hole 21, the baffle 3 rotates with the cover plate split 2, and the rotation path of the first positioning mark 31 thereon passes through the axis of the vertical circle, so that the adjustment range of the floor drain installation position includes the position where the axis (center) of the vertical circle is located, that is, the first positioning mark 31 (referring to the installation position of the drain outlet of the floor drain) can be in a specific circle coaxial with the vertical circle (a circle with a radius twice the distance A between the first positioning mark 31 and the axis of the eccentric through hole 11, such as Figure 6 Universal adjustment (in the horizontal direction) can be achieved within the range shown in FIG. 1 (i.e., the first positioning mark 31 can be adjusted to any position within the specific circular range), while ensuring the compactness of the overall structure (which is conducive to simplifying the structure and optimizing the structural size, and is easy to implement); Figure 5 As shown, when the first positioning mark 31 is on the axis of the vertical circle, the first positioning mark 31 is also the center of the vertical circle (referring to the position of its axis), which is convenient for size measurement and installation positioning of the present invention. The first positioning mark 31 has the above two measurement and positioning functions at the same time, and the design is ingenious, achieving two goals at one stroke.

[0035] To ensure the efficiency of the present invention, Figure 5 and Figure 6 As shown, the floor drain access hole 21 is circular. As mentioned above, the projection of the drain outlet of the floor drain on the horizontal plane in the installed state is generally circular, or other shapes within a circular range. The floor drain access hole 21 is circular, which ensures that the present invention has universal applicability and can ensure the efficiency of implementation. Figure 2 As shown, the first positioning mark 31 is set on the axis of the floor drain access through hole 21 ( Figure 2 As shown, the floor drain access hole 21 is coaxial with the vertical circle), which is beneficial to the compactness of the overall structure and the efficiency of the installation operation.

[0036] In order to ensure the efficiency of the installation operation of the present invention, a second positioning mark 22 is provided on the cover plate body 1, or on the cover plate split 2, or between the cover plate body 1 and the cover plate split 2, which is used to mark the corner of the cover plate split 2 when the first positioning mark 31 is on the axis of the vertical circle. Through the second positioning mark 22, the first positioning mark 31 can be quickly adjusted to the position where the vertical circular axis (center) is located, so as to facilitate the size measurement and the installation positioning of the cover plate of the present invention; in order to facilitate the implementation and identification, preferably, as Figure 5 and Figure 6 As shown, the second positioning mark 22 is arranged between the cover body 1 and the cover split 2 (that is, when the two parts 22a and 22b of the second positioning mark 22 are aligned, the first positioning mark 31 is on the axis of the vertical circle) (when the second positioning mark 22 is arranged on the cover body 1 or the cover split 2, the second positioning mark 22 can be aligned with the corresponding structure, shape or mark).

[0037] In order to ensure the convenience of the installation operation of the present invention, a level 4 is provided on the top surface (top) of the cover body 1, or the cover body split 2, or the baffle 3. In order to facilitate the installation state of the cover body 1 to be horizontal to facilitate the installation of the floor drain, the present invention is provided with a level 4, and no additional measuring tools are required; according to the style design requirements, the level 4 can be selectively provided on the top surface (top) of the cover body 1, the cover body split 2, or the baffle 3; in order to ensure the compactness of the structure, preferably, as Figure 5 and Figure 6 As shown, the level 4 is arranged on the cover 3, and further, the first positioning mark 31 is arranged on the level 4. To ensure low-cost implementation, the level 4 is a bubble type, which is stable and reliable; to balance the compactness of the structure and the accuracy of the measurement, the level 4 is arranged on the axis of the vertical circle (the axis passes through the level 4) or at a position adjacent to the axis of the vertical circle.

[0038] In order to ensure the comfort of the present invention and prevent the odor in the drainage pipe from leaking from the gaps between the structures, a first sealing ring 5 for sealingly connecting with the drainage interface is provided on the bottom surface of the cover body 1 along the radial outer circumference of the vertical circle, and / or a second sealing ring 6 for sealingly connecting the eccentric through hole 11 and the cover body 2 is provided, and / or a third sealing ring 7 for sealingly connecting the drain outlet of the floor drain is provided on the floor drain access through hole 21. In order to ensure the reliability of the sealing connection between the present invention and the drainage interface, preferably, the first sealing ring 5 is used for sealing connection with the inner side of the drainage interface to avoid the negative impact of the uneven edge of the drainage interface on the sealing connection after it needs to be cut and adjusted; in order to ensure the efficiency of the implementation of the sealing connection, such as Figure 1 and Figure 8As shown, the bottom of the cover body 1 (along the radial outer side of the vertical circle) is provided with an annular cover edge 12, and the first sealing ring 5 is sleeved on the cover edge 12. In order to ensure the compactness of the overall structure, it is preferred that Figure 8 As shown, the second sealing ring 6 is embedded in the eccentric through hole 11 , and the third sealing ring 7 is embedded in the floor drain access through hole 21 .

[0039] In order to further ensure the compactness of the overall structure of the present invention, preferably, Figure 2 and Figure 3 As shown, the cover plate split body 2 is embedded in the eccentric through hole 11 (sink hole structure) and does not exceed the top surface of the cover plate body 1; the level 4 is embedded in the cover plate body 1 or the cover plate split body 2 or the baffle 3 (a concave position 41 for accommodating the level 4 is provided on the top surface of the corresponding structure) and does not exceed the top surface of the cover plate body 1; the baffle 3 is embedded in the floor drain access through hole 21. Figure 4 and Figure 8 As shown, the overall structure of the present invention is compact and thin, occupies a small working floor height, and is generally suitable for the installation of floor drains in residential bathrooms.

[0040] In order to ensure the efficiency and standardization of the installation operation of the present invention, it is preferred that Figure 4 As shown, the cover body 1 has a limit clamping portion 13 extending radially along the vertical circle for limiting the cover body 1 and the drainage interface, so as to facilitate the convenience and correctness of the assembly, disassembly or adjustment of the cover body 1. In order to further ensure the compactness of the structure of the present invention, preferably, as Figure 5 and Figure 6 As shown, the cover body 1 is circular.

[0041] When installing the present invention, it is only necessary to cover the cover body 1 on the drainage interface of suitable size; when adjusting, it is only necessary to rotate the cover body 1 and / or the cover body 2, and the horizontal position of the floor drain access hole 21 can be adjusted to achieve the horizontal adjustment of the floor drain installation position; the vertical adjustment of the floor drain installation height can be achieved by cutting the drainage interface (in actual construction work, in order to facilitate the adjustment of the installation height of the floor drain, the drainage interface is a cylindrical structure, such as a vertical pipe section), and adjusting the vertical height of the floor drain access hole 21. When the size of the drainage interface is not compatible with the cover body 1 (the vertical circle), the cover described in the present invention can be used in combination with a special drainage component 10, such as Figure 7 As shown, the dedicated drainage component 10 is provided with a vertical circular drainage interface 101, a drainage outlet 102 connected to the circular drainage interface 101 and used to be connected to a drainage pipe, and a cut pipe section 103 provided between the circular drainage interface 101 and the drainage outlet 102 for adjusting the vertical height of the floor drain access through hole 21. This combined application further ensures the applicability of the present invention. Figure 8As shown, it is a reference diagram of the installation status under the combined application of the present invention (after the vertical height adjustment of the floor drain access hole 21 is completed), the drain outlet of the floor drain can be connected to the adjusted floor drain access hole 21, and the floor tiles can be paved and installed above the filling layer.

[0042] To sum up, the present invention has a simple structure, and the installation and adjustment operations are easy and convenient, which is conducive to the correct installation of the floor drain and the aesthetics of the transition interface between the floor drain and the floor tiles, and even improves the efficiency of floor drain installation and floor tile laying, providing designers, construction workers and owners with a good use experience and application effect.
