Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment manufacturing and processing, and in particular to a bathroom drainer. Background Technology

[0002] The drain assembly is used for draining bathroom floors. The drain assembly includes a pipe body with threads on the outer wall. A filter plate is installed at the upper opening of the pipe body. A rubber sleeve is embedded inside the pipe body. Two retaining rings are fixedly connected to the inner wall of the pipe body. The rubber sleeve is located between the two retaining rings, and the upper and lower ends of the rubber sleeve are in contact with the two openings respectively.

[0003] The installation of the drain assembly involves creating a groove in the ground, with a mounting base fixed inside. A flange nut is secured inside the mounting base using AB glue. Aligned through holes are drilled at the bottom of the mounting base and the groove. The drain pipe passes through these through holes. The drain assembly's tube is then inserted into the threaded hole of the flange nut, and the rubber sleeve of the drain assembly is fitted onto the drain pipe. Tightening the tube connects the drain assembly to the flange nut. The rubber sleeve seals the drain pipe, preventing sewage from flowing between the tube and the drain pipe and affecting sewage discharge.

[0004] The friction between the rubber sleeve and the water pipe is high, so it cannot be directly pressed or pulled. To put the rubber sleeve on or remove it from the drain pipe, you need to rotate it while pressing down or pulling up the rubber pipe. The retaining ring only restricts the vertical direction of the rubber sleeve. When the pipe is turned, the pipe will rotate relative to the rubber sleeve, so it will not drive the rubber sleeve to rotate together, making disassembly and assembly troublesome. Utility Model Content

[0005] The purpose of this utility model is to provide a bathroom drainer, which has the advantage of making it easy to fit a rubber sleeve onto the drain pipe.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A bathroom drain assembly includes a pipe body with threads on its outer wall. A filter plate is installed at one end of the pipe body, and a retaining ring is integrally formed on the inner wall of the other end of the pipe body. A rubber sleeve is embedded inside the pipe body, with the outer diameter of the rubber sleeve matching the inner diameter of the pipe body. One end face of the rubber sleeve contacts the retaining ring. A section of inclined surface one is provided on the outer wall of the other end of the rubber sleeve. The outer diameter of the rubber sleeve decreases as it approaches the opening. Friction grooves are provided on the inner wall of the rubber sleeve. The thickness of the section of the rubber sleeve near the inclined surface one is less than the thickness of the section away from the inclined surface one, and the thickness of the rubber sleeve is greater than the width of the retaining ring. A limiting ring is threaded inside the pipe body. A second inclined surface corresponding to the first inclined surface of the rubber sleeve is provided on the inner wall of the limiting ring near its opening. The first and second inclined surfaces fit together.

[0008] Using the above technical solution, when installing the drain assembly, the rubber hose sleeve is fitted onto the drain pipe. Tightening the limiting ring causes the inclined surface two of the limiting ring to engage with the inclined surface one of the rubber hose sleeve, resulting in a force exerted by the inclined surface two on the inclined surface one. Simultaneously, the other end face of the rubber hose sleeve contacts the retaining ring. Therefore, the retaining ring and the limiting ring compress the rubber hose sleeve, subjecting it to axial and radial forces. This causes the rubber hose sleeve to contract inwards, compressing the outer wall of the drain pipe, thereby reducing the gap between the drain pipe and the rubber hose sleeve and increasing their sealing performance. Similarly, when the limiting ring is turned in the opposite direction, the limiting ring and the retaining ring... The reduced force on the rubber sleeve allows it to return to its original shape, increasing the gap between the rubber sleeve and the drain pipe. This further reduces the force between them, making it easier to separate the rubber sleeve from the drain pipe and facilitating the installation and removal of the drain assembly. Furthermore, the fit between the second and first inclined surfaces increases the contact area between the limiting ring and the rubber sleeve, thus improving the seal between them. Simultaneously, the compression between the limiting ring and the retaining ring creates friction between the rubber sleeve and these surfaces, fixing the rubber sleeve to the pipe body and preventing relative movement that could create gaps and affect the seal.

[0009] Preferably, the device also includes a card, and the end face of the limiting ring away from the second inclined plane has two opposing slots, with the two sides of the card respectively engaging in the two opposing slots of the limiting ring.

[0010] Using the above technical solution, the card ring can be easily twisted by pinching the card.

[0011] Preferably, the outer wall of the tube is integrally formed with a baffle plate that fits against the surface of the filter plate. A rubber ring is fitted on the outer wall of the tube, and a flange nut is threaded onto the outer wall of the tube. The rubber ring is located between the baffle plate and the flange nut.

[0012] Using the above technical solution, the flange nut is fixed to the mounting seat in the ground groove. The pipe body is screwed to make it threadedly connected to the flange nut. The flange nut and the pipe body baffle come closer to each other and squeeze the rubber ring between them, causing the rubber ring to deform. This prevents gaps from forming between the flange nut and the pipe body baffle, so that sewage can flow from between the flange nut and the pipe body into the mounting seat, affecting the discharge of sewage.

[0013] Preferably, a paper ring is fitted onto the outer wall of the tube, and the paper ring is located between the rubber ring and the flange nut.

[0014] By adopting the above technical solution, the sealing between the flange nut and the pipe body is further increased. At the same time, the friction between the paper ring and the flange nut is reduced, which reduces the resistance to the relative movement between the pipe body and the flange nut, thus facilitating the disassembly and assembly of the drainer.

[0015] Preferably, the filter plate has an integrally formed retaining ring on its surface, the retaining ring is elastic, the outer wall of the retaining ring has an integrally formed retaining strip, and the inner wall of the tube has a groove corresponding to the retaining strip, the retaining ring is located inside the tube, and the retaining strip is embedded in the groove.

[0016] Using the above technical solution, a portion of the retaining ring of the filter plate is inserted into the inside of the pipe body. The retaining strip on the retaining ring contacts the edge of the pipe body opening. When the filter plate is pressed down, a force is generated between the retaining strip and the edge of the pipe body opening, causing the retaining strip and retaining ring to deform and contract inward. The retaining strip enters the inside of the pipe body. When the retaining strip moves to the groove, the retaining ring and retaining strip rebound, and the retaining strip is embedded in the groove, thereby connecting the filter plate to the pipe body.

[0017] Preferably, the inclined surface is integrally formed with multiple radial protrusions.

[0018] By adopting the above technical solution, the pressure of the limiting ring on the rubber sleeve is increased, thereby fixing the rubber sleeve more firmly. Attached Figure Description

[0028] See Figure 1 , Figure 4 and Figure 6 A bathroom drain assembly includes a pipe body 1. A baffle plate is integrally formed on the outer wall of the upper opening of the pipe body 1. A rubber ring 10 and a paper ring 12 are fitted onto the outer wall of the pipe body 1. The outer wall of the pipe body 1 has threads, and a flange nut 11 is threaded onto the outer wall of the pipe body 1. The flange nut 11 includes a hexagonal nut and a washer integrally formed on one end face of the hexagonal nut. The washer of the flange nut 11 is close to the baffle plate. The rubber ring 10 and the paper ring 12 are located between the baffle plate and the flange nut 11, with the rubber ring 10 close to the baffle plate and the paper ring 12 close to the flange nut 11. A filter plate 2 is installed at the upper opening of the pipe body 1. The baffle plate is in contact with the surface of the filter plate 2. A retaining ring 13 is integrally formed on the surface of the filter plate 2. The retaining ring 13 is elastic, and a retaining strip 14 is integrally formed on the outer wall of the retaining ring 13. A circular groove 15 corresponding to the retaining strip 14 is formed on the inner wall of the pipe body 1. The retaining ring 13 is located inside the pipe body 1, and the retaining strip 14 is embedded in the groove 15.

[0029] See Figure 2 , Figure 3 and Figure 5 The inner wall of the lower opening of the tube body 1 is integrally formed with a retaining ring 3. A rubber sleeve 4 is embedded inside the tube body 1. The outer wall of the rubber sleeve 4 is in contact with the inner wall of the tube body 1. The rubber sleeve 4 is divided into three sections: upper, middle and lower. The thickness of the rubber sleeve 4 increases as it goes down. A section of inclined surface 5 is provided on the outer wall of the opening at the end of the upper section of the rubber sleeve 4. The outer diameter of the rubber sleeve 4 is smaller as it gets closer to the upper opening on the inclined surface 5, so that the upper section of the rubber sleeve 4 forms a frustum shape. The end face of the lower section of the rubber sleeve 4 is in contact with the surface of the retaining ring 3. The thickness of the rubber sleeve 4 is greater than the width of the retaining ring 3. Friction texture is provided on the inner wall of the rubber sleeve 4.

[0030] See Figure 4 , Figure 5 and Figure 7 The tube body 1 is detachably connected to a limiting ring 6. The inner wall of the tube body 1 and the outer wall of the limiting ring 6 are respectively threaded. The limiting ring 6 is threadedly connected to the tube body 1. The limiting ring 6 is located above the rubber sleeve 4. The inner wall of the lower opening of the limiting ring 6 is provided with a second inclined surface 7 corresponding to the first inclined surface 5 of the rubber sleeve 4. Multiple protruding ridges 16 are integrally formed on the second inclined surface 7. The first inclined surface 5 and the second inclined surface 7 fit together. The upper end face of the limiting ring 6 is provided with two opposite slots 9. It also includes a card 8. The two sides of the card 8 are respectively engaged in the two opposite slots 9 of the limiting ring 6.

[0031] Working principle: Fix the flange nut 11 to the mounting base in the groove 15 of the ground with AB glue, then put the rubber sleeve 4 of the drainer over the opening of the drain pipe, and screw the pipe body 1 downward to make it threadedly connected with the flange nut 11. The part of the drain pipe near its upper opening enters the rubber sleeve 4. At the same time, the flange nut 11 and the baffle of the pipe body 1 approach each other and squeeze the rubber ring 10 and the paper between them, causing the rubber ring 10 and the paper to deform. This prevents gaps from forming between the flange nut 11 and the baffle of the pipe body 1, so that sewage flows from between the flange nut 11 and the pipe body 1 into the mounting base, affecting the discharge of sewage.

[0032] Then, twist the limiting ring 6 downwards. Since the inclined surface 7 of the limiting ring 6 fits against the inclined surface 5 of the rubber sleeve 4, the inclined surface 7 exerts a force on the inclined surface 5. Simultaneously, the other end face of the rubber sleeve 4 contacts the retaining ring 3. Therefore, the retaining ring 3 and the limiting ring 6 compress the rubber sleeve 4, subjecting it to axial and radial forces. The rubber sleeve 4 contracts inwards, compressing the outer wall of the drain pipe, thereby reducing the gap between the drain pipe and the rubber sleeve 4 and increasing their sealing performance. Similarly, twisting the limiting ring 6 in the opposite direction reduces the force exerted by the limiting ring 6 and the retaining ring 3 on the rubber sleeve 4, allowing the rubber sleeve 4 to return to its original shape. The gap between the rubber sleeve and the drain pipe increases, and the force between them decreases, making it easier to separate the rubber sleeve 4 from the drain pipe and facilitating the disassembly and assembly of the drain assembly. Furthermore, the fit between the second inclined surface 7 and the first inclined surface 5 increases the contact area between the limiting ring 6 and the rubber sleeve 4, thereby increasing the sealing performance between the limiting ring 6 and the rubber sleeve 4. At the same time, the compression between the limiting ring 6 and the retaining ring 3 on the rubber sleeve 4 causes friction between the rubber sleeve 4 and the two, thereby fixing the rubber sleeve 4 and the tube body 1 and preventing the relative movement between the two from causing gaps between them, which would affect the sealing performance.

[0033] Then, a portion of the retaining ring 13 of the filter plate 2 is inserted into the tube body 1. The retaining strip 14 on the retaining ring 13 contacts the edge of the upper opening of the tube body 1. The filter plate 2 is pressed down, and a force is generated between the retaining strip 14 and the edge of the opening of the tube body 1, causing the retaining strip 14 and the retaining ring 13 to deform and contract inward. The retaining strip 14 enters the tube body 1. When the retaining strip 14 moves to the groove 15, the retaining ring 13 and the retaining strip 14 rebound, and the retaining strip 14 is embedded in the groove 15, thereby covering the upper opening of the tube body 1 with the filter plate 2.
