Description

Technical Field

[0001] This utility model relates to the technical field of drainers, and in particular to a semi-plastic, semi-steel drainer structure. Background Technology

[0002] Existing semi-plastic, semi-steel drainers typically have a plastic liner and a stainless steel drain pipe body. The stainless steel body is usually directly machined from a stainless steel pipe. This results in the gasket needing to fit tightly against the stainless steel body, making installation very tight. Generally, the gasket needs to be installed under the sink, which is already troublesome; this tight gasket makes installation even more difficult. While the existing stainless steel body also serves as the drain pipe, some sinks are already low to the ground, and if the drain pipe is too long, there's simply no space to connect it to the drain pipe later. Furthermore, the stainless steel drain pipe is not adjustable, making it very inconvenient. Utility Model Content

[0003] This invention aims to overcome the shortcomings of existing technologies, such as the difficulty in installing drainers due to excessively tight gaskets and the difficulty in adjusting the length of stainless steel tail pipes. It provides a semi-plastic, semi-steel drainer structure that is easy to install and allows for convenient adjustment of the tail pipe length.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A semi-plastic, semi-steel drain structure includes a stainless steel flange, a flange gasket, a plastic nut, a filter screen, a push-button valve core, and a water plug. The plastic nut is equipped with a gasket and a tailpipe. The lower end face of the gasket is fixedly connected to the upper end face of the plastic nut. The tailpipe is placed on the lower end face of the plastic nut and is integrally formed with it. The lower end face of the stainless steel flange passes through the upper end face of the plastic nut and is placed inside the plastic nut. The outer surface of the stainless steel flange is threadedly connected to the internal surface of the plastic nut. The flange gasket surrounds the stainless steel flange. The filter screen and the pressure valve core are both placed inside the stainless steel flange on the outer side. The lower end face of the filter screen is snapped into the stainless steel flange, and the lower end face of the pressure valve core is threaded to the filter screen. The upper end face of the pressure valve core is threaded to the water plug. The side of the water plug is in contact with the inside of the stainless steel flange. The cross-sectional shape of the pressure valve core is triangular, and several rib rings are provided on the hypotenuse of the triangle. The cross-sectional shape of the rib rings is arc-shaped and opens upward. The rib rings and the pressure valve core are integrally formed.

[0006] First, install the filter screen, water plug, and push-button valve core. Then, insert the filter screen, water plug, and push-button valve core into the stainless steel flange. Next, place the flange gasket on the outer side of the stainless steel flange, positioning the gasket above the basin. The lower end of the stainless steel flange passes through the upper end of the basin and is placed under the basin. The gasket is already fixed to the plastic nut, so screw the gasket and plastic nut onto the stainless steel flange simultaneously from under the basin. The inner diameter of the gasket can have some extra allowance. Then, drill the triangular tip of the gasket into the basin opening. The upward arc-shaped ridge allows the gasket to better seal the gap between the basin and the stainless steel flange. The upward arc-shaped ridge also blocks the area around the basin opening. If you find that the area under the basin is not large enough, you can cut off the tailpipe before installation. Cutting the plastic tailpipe is easier, achieving the purpose of convenient installation and easy adjustment of the tailpipe length.

[0007] Preferably, the upper surface of the plastic nut has a groove, and the lower end of the gasket is placed in the groove and fixedly connected to the inner wall of the groove. The groove can easily block some water when there is water leakage.

[0008] Preferably, the groove is provided with several drain outlets. One end of each drain outlet passes through the bottom surface of the groove and connects to the upper surface of the plastic nut. The other end of each drain outlet passes through the inner wall of the plastic nut and connects to its interior. The drain outlets are located outside the gasket. These drain outlets facilitate the continued drainage of water leaking from the gasket into the tailpipe.

[0009] Preferably, a retaining ring is provided within the groove, and the retaining ring is integrally formed with the plastic nut. A retaining groove is provided on the inner wall of the gasket, and the retaining ring is placed within the retaining groove and engages with the plastic nut through the groove. The inner diameter of the gasket is the same as the inner diameter of the upper end of the plastic nut. The retaining ring and retaining groove facilitate the connection between the gasket and the plastic nut, preventing deformation of the gasket with a larger inner diameter, thus ensuring a good seal.

[0010] Preferably, the outer surface of the tailpipe is provided with several annular grooves, which are evenly distributed from the lower end of the tailpipe upwards, and the cross-sectional shape of the annular grooves is arc-shaped. The annular grooves facilitate the determination of the cut-off position and prevent deviation.

[0011] Preferably, the outer surface of the plastic nut has several raised ridges, which are evenly distributed on the outer surface of the plastic nut and are integrally formed with the plastic nut. The raised ridges increase friction, making it easier to install the plastic nut by hand.

[0012] The beneficial effects of this utility model are: convenient installation and easy adjustment of the tailpipe length; the groove can easily block some water when there is water leakage; the drain outlet can easily drain the water leaking from the gasket back into the tailpipe; the retaining ring and retaining groove facilitate the connection between the gasket and the plastic nut, preventing the gasket with a larger inner diameter from deforming and thus ensuring a good seal; the annular groove makes it easy to determine the cut position without deviation; the protruding ridge increases friction and makes it easy to install the plastic nut by hand.

The tail pipe 5 is placed on the lower end face of the plastic nut 3 and is integrally formed with the plastic nut 3. The lower end face of the stainless steel flange 1 passes through the upper end face of the plastic nut 3 and is placed inside the plastic nut 3. The outer surface of the stainless steel flange 1 is threadedly connected to the inner surface of the plastic nut 3. The flange gasket 2 surrounds... The outer surface of the stainless steel flange 1 is placed between the stainless steel flange 1 and the gasket 4. The filter screen 6 and the press valve core 7 are both placed inside the stainless steel flange 1. The lower end face of the filter screen 6 is snapped into the stainless steel flange 1. The lower end face of the press valve core 7 is threaded to the filter screen 6. The upper end face of the press valve core 7 is threaded to the water plug 8. The side of the water plug 8 is in contact with the inside of the stainless steel flange 1. The cross-sectional shape of the gasket 4 is triangular. Several rib rings 9 are provided on the hypotenuse of the triangle of the gasket 4. The cross-sectional shape of the rib rings 9 is arc-shaped and the opening is upward. The rib rings 9 and the gasket 4 are integrally formed.

[0020] like Figure 2 and Figure 3 As shown, the upper surface of the plastic connector 3 is provided with a groove 10, and the lower end of the gasket 4 is placed in the groove 10 and fixedly connected to the inner wall of the groove 10.

[0021] like Figure 2 and Figure 3 As shown, the groove 10 is provided with a number of drain outlets 11. One end of the drain outlet 11 passes through the bottom surface of the groove 10 and connects with the upper surface of the plastic nut 3. The other end of the drain outlet 11 passes through the inner wall of the plastic nut 3 and connects with the interior of the plastic nut 3. The drain outlet 11 is placed on the outside of the gasket 4.

[0022] like Figure 2 and Figure 3 As shown, a retaining ring 12 is provided in the groove 10. The retaining ring 12 and the plastic nut 3 are integrally formed. The inner wall of the gasket 4 is provided with a groove 13. The retaining ring 12 is placed in the groove 13 and is engaged with the plastic nut 3 through the groove 13. The inner diameter of the gasket 4 is the same as the inner diameter of the upper end of the plastic nut 3.

[0023] like Figure 2 and Figure 4 As shown, several annular grooves 14 are provided on the outer side of the tailpipe 5. The annular grooves 14 are evenly distributed from the lower end of the tailpipe 5 upwards, and the cross-sectional shape of the annular grooves 14 is arc-shaped.

Then, secure the filter screen 6, water plug 8, and push-button valve core 7 inside the stainless steel flange 1. Next, place the flange gasket 2 on the outer side of the stainless steel flange 1, with the flange gasket 2 above the sink. The lower end of the stainless steel flange 1 should pass through the upper end of the sink and be positioned below the sink. The gasket 4 is already fixed to the plastic nut 3 through the engagement of the retaining ring 12 and the retaining groove 13. Therefore, you can manually screw the gasket 4 and the plastic nut 3 onto the stainless steel flange 1 from below the sink by holding the protruding part of the plastic nut 3 (15). Allow some extra allowance for the inner diameter of the gasket 4. Then, let the gasket... The triangular tip of the gasket 4 is drilled into the opening of the basin. The upward arc-shaped ridge ring 9 allows the gasket 4 to better seal the gap between the basin and the stainless steel flange 1. The upward arc-shaped ridge ring 9 can also block the area around the opening of the basin. If it is found that the area under the basin is not large enough, the tail pipe 5 can be cut off flat according to the corresponding annular groove 14 before installation. Cutting the plastic tail pipe 5 is more convenient. Even if a small amount of water flows out along the gasket 4, the water will flow into the groove 10 and be drained away by the drain outlet 11 in the groove 10 into the tail pipe 5, so there will be no dripping. This achieves the purpose of convenient installation and convenient adjustment of the tail pipe length.
