Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to a drain device. Background Technology

[0002] Traditional drainers insert a connecting pipe into the inlet or outlet end, with external threads on the outer wall of the inlet or outlet end. The connecting pipe is then press-fitted onto the drainer housing via a threaded cap. However, this assembly has the following problems: after the connecting pipe is inserted into the inlet / outlet end, it requires precise manual alignment, which is difficult to perform in narrow spaces. When the cap is tightened, it only provides axial pressure and cannot correct the radial misalignment between the connecting pipe and the connection part. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings and deficiencies of the existing technology and to provide a drain device.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a drainer, comprising a housing, wherein a drain chamber and two connecting parts communicating with the drain chamber are provided within the housing, one connecting part being configured as a water inlet and the other connecting part being configured as a water outlet, and a connecting pipe is inserted into at least one connecting part, the connecting pipe being detachably installed with the connecting part via a connecting assembly; the connecting assembly includes a connecting sleeve and a cap; a first external spiral rib is provided on the outer periphery of the connecting part; the connecting sleeve is sleeved over the connecting pipe and inserted into the connecting part, and its end near the connecting part is provided with... A first limiting ring extends radially outward; the outer periphery of the first limiting ring is provided with a second outer helical rib, and when the first limiting ring abuts against the outer end face of the connecting part, the first outer helical rib and the second outer helical rib are continuously connected along the axial direction of the connecting part to form a complete external thread segment; the inner wall of the cap is provided with at least a portion of an inner helical rib; during the tightening process, the inner helical rib of the cap can simultaneously engage the connecting segment of the first outer helical rib and the second outer helical rib, forcibly driving the connecting sleeve and the connecting part to rotate coaxially until the cap presses the first limiting ring against the outer end face of the connecting part.

[0005] As a preferred embodiment of this utility model, the length of the inner spiral rib of the cap is less than the total length of the combination of the first outer spiral rib and the second outer spiral rib; when the cap is tightened, the inner wall of the cap forms a smooth section corresponding to the second outer spiral rib.

[0006] As a preferred technical solution of this utility model, the outer end face of the connecting sleeve is provided with an elastic compression part, and the cap is provided with an inner blocking part. The inner blocking part has a through hole adapted to the shape of the connecting tube. When the cap is tightened, the inner blocking part abuts against the elastic compression part.

[0007] As a preferred embodiment of the present invention, the elastic compression part includes a first annular rib and a second annular rib arranged at intervals, and a deformation groove with a V-shaped cross-section is formed between the two.

[0008] As a preferred technical solution of this utility model, the inner wall of the through hole is a conical surface, and its diameter gradually decreases from the inside to the outside; when the cap is tightened, the second annular rib is pressed and contacted with the conical surface.

[0009] As a preferred technical solution of this utility model, the inner wall of the connecting sleeve is provided with at least two annular sealing ribs spaced apart along the axial direction.

[0010] As a preferred embodiment of this utility model, the outer wall of the connecting pipe is provided with at least one sealing ring.

[0012] As a preferred embodiment of this utility model, one connecting part is located at the upper end of the shell, and the other connecting part is located on the side wall of the shell; both connecting parts are provided with the connecting pipe, and the axes of the two connecting pipes are perpendicular to each other.

[0013] As a preferred embodiment of this utility model, a sealing cap is threadedly connected to the bottom of the housing.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: when the cap is tightened, the inner spiral rib can simultaneously engage the connecting part of the double-segment outer spiral rib, forcibly driving the connecting sleeve and the connecting part to be dynamically coaxial. When the cap is tightened to the end, the inner spiral rib disengages from the second outer spiral rib. At this time, the first limiting ring presses against the outer end face of the connecting part, and the installation can be completed. The length of the inner spiral rib is shorter than the total length of the double-segment outer thread, forming a non-engaging area at the smooth section. When disassembling, the inner spiral rib of the cap disengages from the first outer spiral rib of the connecting part, and the disassembly and assembly can be completed. Attached Figure Description

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-5 The drain device shown includes a housing 1, within which a drain chamber 2 and two connecting parts 3 (preferably cylindrical and hollow) communicating with the drain chamber 2 are provided. One connecting part 3 is configured as a water inlet, and the other connecting part 3 is configured as a water outlet. A connecting pipe 4 is inserted into at least one connecting part 3, and the connecting pipe 4 is detachably installed in connection with the connecting part 3 via a connecting assembly. The connecting assembly includes a connecting sleeve 5 and a cap 6. The outer periphery of the connecting part 3 is provided with a first external spiral rib 7. The connecting sleeve 5 is sleeved over the connecting pipe 4 and inserted into the connecting part 3, and its end near the connecting part 3 has a radially outward... The first limiting ring 8 extends; the outer periphery of the first limiting ring 8 is provided with a second outer spiral rib 9, and when the first limiting ring 8 abuts against the outer end face of the connecting part 3, the first outer spiral rib 7 and the second outer spiral rib 9 are continuously connected along the axial direction of the connecting part 3 to form a complete external thread segment; the inner wall of the screw cap 6 is provided with at least a portion of an inner spiral rib 10; during the tightening process, the inner spiral rib 10 of the screw cap 6 can simultaneously engage the connecting section of the first outer spiral rib 7 and the second outer spiral rib 9, forcibly driving the connecting sleeve 5 and the connecting part 3 to rotate coaxially until the screw cap 6 presses the first limiting ring 8 against the outer end face of the connecting part 3.

[0024] When the cap 6 is tightened, the inner spiral rib 10 can simultaneously engage the connecting part of the double-section outer spiral rib, forcibly driving the connecting sleeve 5 and the connecting part 3 to be dynamically coaxial. When the cap 6 is tightened to the end, the inner spiral rib 10 disengages from the second outer spiral rib 9 (the second outer spiral rib 9 corresponds to the non-engaging area at the smooth section 11). At this time, the first limit ring 8 is pressed against the outer end face of the connecting part 3, and the installation is completed.

[0025] The length of the inner spiral rib 10 of the cap 6 is less than the total length of the combination of the first outer spiral rib 7 and the second outer spiral rib 9. When the cap 6 is tightened, the inner wall of the cap 6 forms a smooth section 11 corresponding to the second outer spiral rib 9. The length of the inner spiral rib 10 is shorter than the total length of the double-segment external thread, forming a non-engaging area at the smooth section 11. When disassembling, the inner spiral rib 10 of the cap 6 can be disengaged from the first outer spiral rib 7 of the connecting part 3 to complete the disassembly and assembly.

[0026] The outer end face of the connecting sleeve 5 is provided with an elastic compression part 12, and the cap 6 is provided with an inner blocking part 13. The inner blocking part 13 has a through hole 14 that matches the shape of the connecting tube 4. When the cap 6 is tightened, the inner blocking part 13 abuts against the elastic compression part 12.

[0027] The elastic compression part 12 includes a first annular rib 15 and a second annular rib 16 spaced apart, forming a deformation groove with a V-shaped cross-section between them. In this embodiment, the elastic compression part 12 can be made of elastic materials such as rubber, silicone, or plastic. It can be integrally molded with the screw cap 6, or connected and fixed by snap-fit, plug-in, or other methods. The specific implementation method is not limited to the above forms.

[0028] The inner wall of the through hole 14 is a tapered surface 17, and its diameter gradually decreases from the inside to the outside. When the cap 6 is tightened, the second annular rib 16 is pressed into contact with the tapered surface 17. When the tapered surface 17 gradually decreases into contact with the second annular rib 16, the second annular rib 16 is elastically deformed, which increases the radial locking force and achieves the effect of preventing loosening.

[0029] The inner wall of the connecting sleeve 5 is provided with at least two annular sealing ribs 18 spaced axially, or the outer wall of the connecting pipe 4 is provided with at least one sealing ring.

[0030] The inner end of the connecting sleeve 5 is provided with a radially extending second limiting ring 19, and the inner end of the connecting pipe 4 can abut against the second limiting ring 19 for limiting.

[0031] One of the connecting parts 3 is located at the upper end of the housing 1, and the other connecting part 3 is located on the side wall of the housing 1; both connecting parts 3 are provided with the connecting pipe 4, and the axes of the two connecting pipes 4 are perpendicular to each other; a sealing cap 20 is threadedly connected to the bottom of the housing 1.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples of this utility model and are not intended to limit it. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
