TECHNICAL FIELD

[0001] The present application relates to the technical field of bathroom equipment, in particular to a quick-mounting nut assembly and a bathroom kit. BACKGROUND

[0002] In the bathroom equipment, the drain pipeline of the washbasin is usually provided with a nut fastener. For example, the Chinese patent CN215053582U entitled "Embedded drain installation system" disclosed on December 7, 2021 provides such a nut fastener which is sleeved outside the drain connection pipe at the bottom of the basin. A series of gaskets such as special-shaped pads and rubber washers are also accompanied by the nut fastener. During assembly, these gaskets need to be aligned and sleeved outside the drain connection pipe in sequence, and then the nut is suspended and screwed. The whole assembly process is complicated and requires many small parts, which are usually difficult to assemble and easy to lose. SUMMARY

DETAILED DESCRIPTION

[0025] Referring now to the drawings, the schematic arrangement of the quick nut assembly and the bathroom set disclosed by the present application will be described in detail. Although the drawings are provided to present some embodiments of the present application, the drawings are not necessarily drawn to scale according to the size of the specific embodiments, and some features can be enlarged, removed or partially cut to better show and explain the disclosure of the present application. Some components in the drawings can be adjusted in position according to actual needs without affecting the technical effects. The phrase "in the drawings" or similar language appearing in the specification does not necessarily refer to all drawings or examples.

[0026] Some directional terms used to describe the drawings in the following, such as "inner", "outer", "upper", "lower" and other directional terms, will be understood to have their normal meanings and refer to those directions involved when normally looking at the drawings. Unless otherwise specified, the directional terms described in the specification are basically according to the conventional directions as understood by those skilled in the art.

[0027] The terms "first", "first", "second", "second" and similar terms used in the present invention do not indicate any order, quantity or importance, but are used to distinguish one component from other components.

[0028] The quick-install nut assembly according to the present invention is particularly suitable for quick installation of bathroom equipment, especially drainage pipes of wash basins. Figures 1 to 4 An embodiment of a quick-release nut assembly according to the present invention is shown. As shown, the quick-release nut assembly includes a pressure plate 1 and a sleeve 2, which can be detachably assembled. "Detachable" as used herein means that after being assembled or connected, multiple independent components can be disassembled again to restore them to their original form and / or function. This disassembly does not involve destroying these components, thereby substantially preserving their original form and / or function.

[0029] like Figure 1 and Figure 2 As shown, the pressure plate 1 is annular as a whole, and the main body is an annular plate body 11. The top surface 111 of the plate body 11 is used to rest against the bottom of the basin during assembly. Extrusion ribs 112 can be formed on the top surface 111 of the plate body 11, so that the basin can apply force to the top surface 111 to achieve the expected extrusion effect. In the embodiment shown, the extrusion ribs 112 are a plurality of concentric annular protrusions extending around the inner hole 113 of the plate body 11. It can be understood that the shape of the extrusion ribs 112 is not limited to this, as long as it can facilitate the basin to squeeze the plate body 11 so that the plate body 11 is deformed as expected. For example, in an embodiment not shown, the extrusion ribs 112 can be a plurality of linear protrusions formed on the top surface 111 in a crisscross grid-like pattern. In other embodiments, the extrusion ribs 112 can be protrusions of other shapes.

[0030] On the side of the plate body 11 facing away from the top surface 111, a boss is provided near the inner hole 113, and the boss extends along the circumference of the inner hole 113. An extrusion surface 114 is formed on the inner circumferential surface of the boss facing the inner hole 113, which is used to cooperate with the joint surface of the sleeve 2, which will be described in detail later. In the embodiment shown, the distance between the extrusion surface 114 and the central axis of the plate body 11 gradually increases in the direction approaching the sleeve 2 along the central axis. When viewed in a longitudinal section of the plate body 11, the extrusion surface 114 can be an oblique straight surface or an arc surface. In one embodiment, the extrusion surface 114 extends from the periphery of the inner hole 113 into a truncated cone shape, or a drum shape with different diameters at both ends. The outer circumferential surface of the boss facing away from the inner hole 113 can be simply set as a circular surface equidistant from the central axis of the plate body 11. Alternatively, the outer circumferential surface of the boss facing away from the inner hole 113 can be parallel to the inner circumferential extrusion surface 114.

[0031] The side of the plate body 11 facing away from the top surface 111 is also provided with a plurality of elastic claws 12. These elastic claws 12 are arranged along the circumference of the plate body 11 near the outer peripheral edge of the plate body 11. The embodiment shown in the figure shows two groups of four elastic claws 12, which are arranged symmetrically with respect to the axial mid-section of the plate body 11. The number and arrangement of the elastic claws 12 are not limited here and can be increased or decreased as needed, but a minimum of two is required.

[0032] A plurality of elastic reset ribs 15 are further provided on the side of the plate body 11 facing away from the top surface 111. These reset ribs 15 are arranged along the circumference of the plate body 11 and close to the outer peripheral edge of the plate body 11. Figure 2 As shown, each reset rib 15 has an elastic cantilever 151 extending away from the plate body 11, and the free end of the elastic cantilever 151 extends obliquely. In one embodiment, the elastic cantilever 151 can extend into a hook shape or an arc shape. A plurality of reset ribs 15 can be arranged concentrically with a plurality of elastic claws 12. In the embodiment shown, each reset rib 15 is arranged between two adjacent elastic claws 12. As mentioned above, the two groups of elastic claws 12 are arranged symmetrically with respect to the axial mid-section of the plate body 11, wherein a gap is formed between the two elastic claws 12 of each group, and a reset rib 15 is arranged in the gap, and there is a gap 14 between the reset rib 15 and the two elastic claws 12.

[0033] In one embodiment, the pressing plate 1 may be an integral part made by an integral molding process (eg, injection molding, additive manufacturing technology, etc.).

[0034] like Figures 1 to 4As shown, the sleeve 2 is configured to be detachably engaged with the platen 1, and when engaged, its axial through hole 21 is aligned with the inner hole 113 of the platen 1. The sleeve 2 comprises a body 4 and a hand grip 3. The body 4 is annular, and its outer periphery forms a cylindrical wall 41, and a plurality of clamping slots 411 are formed in the cylindrical wall 41 for engaging the elastic clamping jaws 12 of the platen 1. In the embodiment shown, the inner side of the cylindrical wall 41 further forms a plurality of pairs of radial protrusions 412, wherein each pair of radial protrusions 412 corresponds to one reset rib 15. When the platen 1 is assembled with the sleeve 2, the elastic cantilever arms 151 of the reset ribs 15 are pressed between the corresponding pair of radial protrusions 412 and elastically deformed. For the reset rib 15 located between the two elastic clamping jaws 12 of each group, the corresponding pair of radial protrusions 412 are inserted between the reset rib 15 and the two elastic clamping jaws 12 at the interval 14 therebetween. The design of the radial protrusions 412 inserted in the interval 14 enables the rotation of the sleeve 2 to drive the platen 1 to rotate together. An elastic thread 42 extending along the circumference of the body 4 is formed in the inner periphery of the body 4. As shown, two elastic threads 42 are symmetrically arranged with respect to the median section of the sleeve 2. The bottom of each elastic thread 42 is configured as an elastically deformable elastic connection 424, and on top of the elastic connection 424, a plurality of (e.g. two) thread segments 421 are engaged, which are arranged along the circumference of the body 4, and each thread segment 421 extends along the circumference of the body 4. The elastic connection 424 is configured to apply a force to the engaged thread segments 421 to spread them away from the central axis of the sleeve 2 rather than to gather them towards the central axis. The configuration of the elastic connection 424 can be various, such as a deformable elastic strip connected between the plurality of thread segments 421, etc. At least a portion (e.g. the middle portion) of the elastic strip can be arc-shaped with the concave side facing the central axis of the sleeve 2.

[0035] The side of the thread segment 421 facing the central axis of the sleeve 2 forms a thread 422, and the side facing away from the central axis forms an engagement surface 423 for cooperating with the aforementioned pressing surface 114 of the platen 1. In the embodiment shown, the distance of the engagement surface 423 to the central axis of the sleeve 2 tapers in the direction towards the platen 1 along the central axis. From the longitudinal section of the sleeve 2, the engagement surface 423 can be a straight inclined surface or an arc surface. The shape of the engagement surface 423 can be adapted to the shape of the pressing surface 114, so that when the platen 1 is engaged with the sleeve 2, the pressing surface 114 is completely fitted to the engagement surface 423.

[0036] In one embodiment, a space is formed between the two elastic threads 42, and a stop protrusion 13 is formed on the side of the plate body 11 away from the top surface 111, corresponding to the space. When the pressing plate 1 is engaged with the sleeve 2, the stop protrusion 13 is inserted between the two elastic threads 42, limiting the rotation of the elastic threads 42. In one embodiment, the stop protrusion 13 can be protruding from the extrusion surface 114 towards the central axis of the plate body 11.

[0037] In one embodiment, the position of the elastic threads 42, especially the engaging surface 423, is higher than the height of the outer peripheral wall 41 of the body 4 in the axial direction.

[0038] The cylindrical hand-held portion 3 is engaged to the body 4 on the side of the body 4 away from the pressing plate 1. The hand-held portion 3 can be formed with a concave-convex texture 31 on the outer periphery, such as the longitudinal and transverse interlaced convex ridges as shown, to help increase the friction, facilitate gripping and force application.

[0039] In one embodiment, the sleeve 2 can be a one-piece made by an integral forming process (such as injection molding, additive manufacturing technology, etc.).

[0040] The working principle of the quick nut assembly of the present application will be described in detail below. Figure 5 and Figure 6 The working principle of the quick nut assembly of the present application will be described in detail below.

[0041] Referring to Figure 5 , when initially installed, the pressing plate 1 is loosely mounted on the body 4 of the sleeve 2 without applying pressure to both. The quick nut assembly is sleeved on the threaded pipe 6. At this time, since neither the pressing plate 1 nor the elastic threads 42 are deformed, the quick nut assembly can be easily and quickly sent along the threaded pipe 6 to the position in contact with the bottom surface of the basin 5.

[0042] With reference to Figure 6 , continue to push the quick nut assembly towards the bottom surface of the basin 5, so that the pressing plate 1 is forced to abut against the bottom surface of the basin 5. At this time, the pressing plate 1 falls into the body 4 of the sleeve 2 in the vertical direction and the elastic clamping jaws 12 are buckled into the clamping openings 411 of the body 4, and at the same time the pressing plate 1 is pushed by the bottom surface of the basin 5, so that the extrusion surface 114 abuts against the engaging surface 423 of the elastic threads 42, extruding the threaded segments 421 of the elastic threads 42 and making them shrink radially inward to tightly embrace the threaded pipe 6 against the force of the elastic connecting portions 424. Next, the quick nut assembly can be continuously rotated to be tightened on the threaded pipe 6. In this state, the stop protrusion 13 of the pressing plate 1 is inserted into the space between the elastic threads 42 to prevent the elastic threads 42 from being randomly rotated, while the radial protrusions 412 of the sleeve 2 are inserted into the space 14 between the corresponding reset ribs 15 and the elastic clamping jaws 12, and the elastic cantilever arms 151 of the reset ribs 15 are elastically deformed between the pair of radial protrusions 412.

[0043] To disassemble the quick-release nut assembly, the assembly is rotated in the opposite direction. The threaded section 421 of the elastic threaded body 42 automatically expands under the action of the elastic connection portion 424 of the elastic threaded body 42, allowing disassembly. The elastic claw 12 is then separated from the retaining hole 411. The pressure plate 1 can then be easily separated from the main body of the sleeve 2 under the action of the reset rib 15.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
