[0001] The utility model relates to the field of building drainage, in particular to an adjusting cover for installing a downward-draining floor drain and an adapter seat applying the same. Background Art
[0002] When installing a downward-draining floor drain, a vertical interface needs to be preset in the drainage pipe for connecting the drain outlet of the floor drain. This interface is usually a circular pipe orifice structure. For efficient drainage or to avoid blockage, the drainage pipe will select a larger specification as required (leaving a redundancy), which will result in a gap between the drain outlet of the floor drain and the above interface. To prevent sundries such as building slurry from falling into the drainage pipe from the above gap, there are floor drains equipped with a cover plate for covering the gap. However, the functional cover plate of the prior art cannot or is inconvenient to adjust the installation position of the floor drain, or its structural compactness and use convenience are poor.

[0020] To better understand the above technical solution, the exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings, which are intended to explain the present utility model and should not be construed as a limitation to the present utility model.
[0021] An adjusting cover for installing a bottom-drainage floor drain, which is used to cover the gap between the floor drain (drainage port) and the vertical circular interface, includes a main cover plate 1 and an adjusting plate 2; a limiting portion 11 that is circumferentially limited and matched with the interface is provided at the bottom of the main cover plate 1, so that the main cover plate 1 can be rotatably covered on the interface, and a through hole 12 communicating with the interface is provided on the plate surface; the adjusting plate 2 can be movably covered on the through hole 12, and a floor drain installation hole 21 (for connecting the drainage port of the floor drain) communicating with the through hole 12 is provided on the plate surface; the main cover plate 1 is circular, the through hole 12 is provided at the center of the main cover plate 1 and extends along its radial direction, and the floor drain installation hole 21 can reciprocally move along the extension direction of the through hole 12 with the adjusting plate 2, and adjust its position within the range of the through hole 12.
[0022] The structure of this adjusting cover is simple. As Figure 1 shown, it is composed of two parts, the main cover plate 1 and the adjusting plate 2. In the application state, the through hole 12 communicates with the inner side of the interface, and is located at the position of the center ( Figure 2 point O in) of the main cover plate 1 and extends along the radial direction of the main cover plate 1, and can adjust the angle within the range of the interface as the main cover plate 1 rotates; the floor drain installation hole 21 communicates with the inner side of the through hole 12 and can adjust its position within the range of the through hole 12 as the adjusting plate 2 moves (obviously, the size of the floor drain installation hole 21 is smaller than that of the through hole 12). The present utility model is applicable to the situation where the size of the floor drain drainage port is smaller than that of the interface. This adjusting cover can not only cover the gap between the floor drain (drainage port) and the interface, but also freely adjust the position of the floor drain installation hole 21 within the range of the interface by rotating the main cover plate 1 and moving the adjusting plate 2, that is, can adjust the installation position of the floor drain. As Figure 4 shown, it is the top view (comparison) diagram of adjusting the position of the floor drain installation hole 21 by rotating the main cover plate 1 and moving the adjusting plate 2.
[0023] The drainage port of the bottom-drainage floor drain is usually designed based on a circular interface for better applicability. The two ends of the through hole 12 are semi-circular, the middle part is rectangular, and the floor drain installation hole 21 is circular. As Figure 2 and Figure 3As shown, this structure is widely applicable to the bottom - type floor drain in the prior art. For the sake of structural compactness, the radius of the floor drain installation hole 21 is equal to or slightly larger than the radius of the floor drain drainage port, and at the same time, it is equal to or slightly smaller than the radius at both ends of the through - hole 12.
[0024] For ease of use, a diversion port 211 (circular) is provided downward (extending downward along its circumference) in the floor drain installation hole 21. The diversion port 211 extends into the through - hole 12, so that the floor drain installation hole 21 is limited within the range of the through - hole 12 (limiting the movement range of the adjusting plate 2), as Figure 1 and Figure 5 shown. This structure can also prevent sewage from seeping out through the gap between the adjusting plate 2 and the main cover plate 1. For further structural compactness, the diversion port 211 and the through - hole 12 are in clearance fit. At this time, they can also limit the movement direction of the adjusting plate 2, achieving three purposes at once.
[0025] To limit the movement direction of the adjusting plate 2, the following structure can also be adopted, that is, a clamping groove 13 is provided on the top of the main cover plate 1. The adjusting plate 2 is embedded in the clamping groove 13 and is in limit fit with it along a parallel track, as Figure 2 and Figure 4 shown. The clamping groove 13 protrudes upward on the top surface of the main cover plate 1 and is U - shaped. The adjusting plate 2 is embedded in it and is in limit fit with its two sides along a parallel track. The principle is clear at a glance and is convenient for use. Of course, the structural pattern of the clamping groove 13 can be diverse, (by adopting different structural patterns) and it can even play a role in limiting the movement range of the adjusting plate 2. No matter what structural pattern the clamping groove 13 adopts, for ease of use and efficient implementation, the limit fit between the adjusting plate 2 and the clamping groove 13 is a clearance fit.
[0026] For further ease of use, a limiting block 22 and a limiting notch 121 for mutual limit fit are provided between the adjusting plate 2 and the main cover plate 1, so that the floor drain installation hole 21 is limited within the range of the through - hole 12 (limiting the movement range of the adjusting plate 2), as Figure 3As shown, the limit clamping block 22 is provided on the bottom surface of the adjusting plate 2 and is located on both sides of its moving direction (the floor drain installation hole 21). Correspondingly, the limit notches 121 are formed by expanding outward on both sides of the extending direction of the through hole 12. The limit clamping block 22 extends into the limit notches 121, and the two are in limit cooperation. Of course, the implementation manners of the limit clamping block 22 and the limit notches 121 can be various. For example, the limit clamping block 22 is provided on both sides of the plate surface of the adjusting plate 2, and the limit notches 121 are correspondingly provided on the clamping groove 13, or the limit clamping block 22 is provided on the clamping groove 13, and the limit notches 121 are correspondingly provided on both sides of the plate surface of the adjusting plate 2, etc. In addition, the structural styles of the two can also be various. (By adopting different structural styles), it can even play a role in limiting the moving direction of the adjusting plate 2. Therefore, in view of the fact that the limit clamping block 22 and the limit notches 121 overlap with the clamping groove 13 in function, in actual implementation, the limit clamping block 22, the limit notches 121, and the clamping groove 13 can be implemented simultaneously or one of them can be selected for implementation.
[0027] For the sake of a better covering effect, the limiting part 11 is a circular ring structure and is sleeved on the inner side and / or the outer side of the interface. As Figure 1 and Figure 5 shown, the circular ring-shaped limiting part 11 is downwardly provided on the bottom surface of the main cover plate 1 and is sleeved into the inner side of the interface. This structure prevents sundries from falling into the drainage pipe through the gap between the main cover plate 1 and the interface (acting as a retaining function), especially suitable for the case where the interface is uneven. Of course, the structural style of the limiting part 11 can be various. Any structure that is used for circumferentially limiting and cooperating with the interface to ensure that the main cover plate 1 is rotatably limited on the interface belongs to the scope of the limiting part 11. No matter what structural style is adopted, for the convenience of use and efficient implementation, the limiting cooperation between the limiting part 11 and the interface is a clearance fit.
[0028] A adapter includes the adjusting cover and the mounting seat 3. The mounting seat 3 includes a vertical cylinder 31 with a circular cylinder opening 311 at the top and whose height dimension can be cut and reduced, and a pipe interface 32 provided on the cylinder 31 and communicating with the cylinder opening 311 (for connecting the drainage pipe). The adjusting cover covers the cylinder opening 311 (equivalent to the above-mentioned interface). The structure of this adapter is simple. As Figure 1 shown, it is composed of two components, namely the adjusting cover and the mounting seat 3. By cutting the cylinder 31, the height of the cylinder opening 311 can be adjusted to adapt to (adjust) the installation height of the floor drain. That is, this adapter can not only cover the gap between the floor drain (drainage opening) and the cylinder opening 311, but also adjust the installation position and installation height of the floor drain, which is beneficial to the efficient and correct installation of the floor drain.
[0029] To be applicable to the installation environment where the drainage pipe is horizontally arranged, the pipe interface 32 is horizontally provided on the cylinder 31, and the axial angle between the two is α, and α > 90° (the pipe interface 32 is inclined downward, with high drainage efficiency). As Figure 5As shown, this structure is particularly suitable for buildings with a same-floor drainage structure of a slightly lowered floor slab (or no lowered floor slab).
