According to the utility model discloses a fast-assembling nut component is particularly useful for sanitary bath equipment, especially wash basin's water drainage pipe's quick installation. Figures 1-7 illustrate one embodiment of a quick-fit nut assembly according to the present invention. As shown, the quick nut assembly includes a pressure plate 1, a sleeve 2, and an elastic threaded body 7 that can be removably assembled together. As used herein, "detachable" means that a plurality of individual components, once assembled or connected together, can be separated again to restore the individual components, without the need to break the individual components, thereby substantially maintaining the original form and/or function of the individual components prior to assembly.

As shown in fig. 1 to 4, the pressing plate 1 is annular, and the main body is an annular plate body 11, and the top surface 111 of the plate body 11 is used for abutting against the bottom of the basin during assembly. A pressing ridge 112 may be formed on the top surface 111 of the plate body 11 to facilitate the basin to apply a desired pressing effect to the top surface 111. In the illustrated embodiment, the crush ribs 112 are a plurality of concentric annular protrusions extending around the inner bore 113 of the plate body 11. It is understood that the shape of the pressing ribs 112 is not limited thereto, as long as the pressing of the tub against the plate body 11 is facilitated to deform the plate body 11 as desired. For example, in one embodiment not shown, the crush ribs 112 may be a plurality of linear ridges formed on the top surface 111 in a criss-cross grid pattern. In other embodiments, the crush ribs 112 may be protrusions that form other shapes.

On the bottom surface of the plate body 11 facing away from the top surface 111, an inner ring boss 114 is provided near the inner hole 113, and the inner ring boss 114 extends in the circumferential direction of the inner hole 113. A pressing surface 115 is formed on an inner circumferential surface of the inner ring boss 114 facing the inner bore 113 for engagement with an engagement surface of the elastic screw body 7 to be described later in detail. In the embodiment shown, the distance of the pressing surface 115 to the central axis of the plate body 11 increases in the direction along the central axis closer to the sleeve 2. The pressing surface 115 may be a slanted straight surface or a curved surface as viewed in a longitudinal section of the plate body 11. In one embodiment, the pressing surface 115 extends from the periphery of the inner bore 113 in a circular truncated cone shape or a drum shape with two different diameters. The outer peripheral surface of the inner ring boss 114 may simply be provided as a circumferential surface equidistant from the central axis of the plate body 11. Alternatively, the outer circumferential surface of the inner ring boss 114 facing away from the inner bore 113 may be parallel to the pressing surface 115 of the inner circumference.

A plurality of resilient claws 12 are also provided on the bottom surface of the plate body 11 facing away from the top surface 111, and these resilient claws 12 are arranged in the circumferential direction of the plate body 11 at positions close to the outer periphery of the plate body 11. In the illustrated embodiment, an outer ring boss 116 may be formed on the bottom surface of the plate body 11 at a position near the outer peripheral edge, and the elastic claws 12 may be formed on the outer ring boss 116. The embodiment in the figures shows four resilient jaws 12 arranged equidistantly apart. The number and arrangement of the resilient jaws 12 is not limited herein and can be increased or decreased as desired, but is at least two.

In one embodiment, the platen 1 may be a unitary piece made by an integral molding process (e.g., injection molding, additive manufacturing techniques, etc.).

As shown in fig. 1, 2, 6 and 7, the sleeve 2 is configured to be removably engageable with the pressure plate 1, and when engaged, its axial through bore 21 is aligned with the internal bore 113 of the pressure plate 1. The sleeve 2 comprises a body 4 and a grip 3. The body 4 is annular and includes a bottom wall 44 and an outer peripheral wall 41 formed around the outer periphery of the bottom wall 44, wherein the bottom wall 44 and the outer peripheral wall 41 together enclose an inner space 43 of the body 4 for accommodating the elastic screw body 7. A plurality of bayonets 411 are formed in the bottom wall 44 adjacent the peripheral wall 41 for engaging the resilient claws 12 of the pressure plate 1. In the illustrated embodiment, the inner side of the peripheral wall 41 is further formed with a plurality of pairs of radial projections 42, and correspondingly, a plurality of pairs of engagement grooves 117 are formed in the outer annular boss 116 of the pressure plate 1, each pair of radial projections 42 being adapted to be inserted into a corresponding pair of engagement grooves 117. The engagement of the radial projection 42 in the engagement groove 117 is designed such that the rotation of the sleeve 2 drives the platen 1 to rotate together.

The cylindrical hand-held portion 3 is joined to the body 4 on a side of the body 4 facing away from the pressure plate 1. The grip portion 3 may be formed with a textured texture 31 on the periphery, such as criss-cross ridges as shown, to help increase friction, facilitate gripping and application of force.

In one embodiment, the sleeve 2 may be a unitary piece made by an integral molding process (e.g., injection molding, additive manufacturing techniques, etc.).

As shown in fig. 1, 2 and 5, the elastic screw body 7 is accommodated in the inner space 43 of the sleeve 2 and is located between the pressing plate 1 and the sleeve 2. The elastic screw body 7 can also be detached from the sleeve 2. The elastic threaded body 7 is integrally configured to surround the axial through hole 21 of the sleeve 2. As shown in the figure, four thread segments 71 in the elastic thread body 7 are arranged at regular intervals around the axial through hole 21, and an elastic connection portion 72 is connected between adjacent two thread segments 71. Each thread section 71 extends in the circumferential direction of the sleeve 2. The side of the threaded section 71 facing the central axis of the sleeve 2 forms a thread 711, while the side facing away from the central axis forms an engagement surface 712 for engagement with the aforementioned pressing surface 115 of the pressure plate 1. In the illustrated embodiment, the distance of the engagement face 712 to the central axis of the sleeve 2 tapers in a direction along the central axis closer to the platen 1. The engagement surface 712 may be a slanted straight surface or a curved surface, as seen in a longitudinal section of the sleeve 2. The shape of the engagement surface 712 and the pressing surface 115 may be adapted such that the pressing surface 115 completely fits to the engagement surface 712 when the elastic screw body 7 is pressed between the pressing plate 1 and the sleeve 2. The resilient connection 72 is configured to apply a force to the engaged threaded section 71 that causes it to expand away from the central axis of the sleeve 2 rather than converging closer to the central axis. The configuration of the resilient connection 72 may be varied, such as a deformable resilient strap or the like connected between adjacent thread segments 71. In the illustrated embodiment, at least a portion (e.g., a middle portion) of the elastic strip is arcuate with a concavity facing the central axis of the sleeve 2.

In one embodiment, four thread segments 71 form a space therebetween, corresponding to which a stop projection 13 is formed on the side of the plate body 11 facing away from the top surface 111. When the pressing plate 1 is pressed against the elastic threaded body 7, the stop protrusion 13 is inserted between two adjacent thread sections 71, limiting the rotation of the elastic threaded body 7. In one embodiment, the stop protrusion 13 may protrude from the pressing surface 115 toward the central axis of the plate body 11.

In one embodiment, the position of the elastic threaded body 7, in particular of the engagement face 712, is axially higher than the height of the peripheral wall 41 of the body 4.

In addition, in order to prevent the elastic screw body 7 and the sleeve 2 from generating undesired relative movement, a limiting structure in concave-convex matching is further arranged between the elastic screw body 7 and the sleeve 2. As shown in the figure, a radially protruding stopper protrusion 713 may be formed at each thread section 71 of the elastic thread body 7, and a stopper groove 412 may be formed at the outer circumferential wall 41 of the sleeve 2. When assembled, the limiting protrusions 713 may be inserted into the corresponding limiting grooves 412.

The working principle of the quick nut assembly of the present invention will be described in detail with reference to fig. 8 and 9.

Referring to fig. 8, in the initial installation, the pressing plate 1 and the elastic screw body 7 are loosely mounted on the body 4 of the sleeve 2, and the limit protrusion 713 of the elastic screw body 7 is inserted into the limit groove 412 of the sleeve 2, but pressure is not applied to the three. And sleeving the quick-assembly nut assembly on the threaded pipe 6. At this time, since neither the pressing plate 1 nor the elastic screw body 7 is deformed, the quick nut assembly can be easily and quickly brought into contact with the bottom surface of the counter basin 5 along the screw tube 6.

Referring to FIG. 9, continued pushing of the quick nut assembly in a direction toward the bottom surface of the counter basin 5 forces the pressure plate 1 against the bottom surface of the counter 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 claws 12 are buckled into the bayonets 411 of the body 4, and at the same time, the pressing plate 1 is pushed by the bottom surface of the counter basin 5, so that the pressing surface 115 abuts against the joint surface 712 of the elastic screw body 7, presses the thread section 71 of the elastic screw body 7, and overcomes the force of the elastic connecting part 72 to contract radially inwards to hold the threaded pipe 6. The quick nut assembly may then continue to be rotated to tighten it onto the threaded tube 6. In this state, the stopper protrusions 13 of the pressure plate 1 are inserted into the spaces between the thread segments 71, preventing the elastic screw body 7 from being freely rotated, and the radial protrusions 42 of the sleeve 2 are inserted into the corresponding engagement grooves 117 of the pressure plate 1.

When the quick-assembly nut assembly needs to be disassembled, the quick-assembly nut assembly is rotated reversely, and the thread section 71 of the elastic thread body 7 is automatically unfolded under the action of the elastic connecting part 72 of the elastic thread body 7, so that the disassembly can be realized. After that, the elastic claw 12 is separated from the bayonet 411, and the pressing plate 1 and the elastic screw body 7 can be easily separated from the socket 2.

It should be understood that although the description is in terms of various embodiments, not every embodiment includes only a single embodiment, and such description is for clarity purposes only, and those skilled in the art will recognize that the embodiments described herein may be combined as suitable to form other embodiments, as will be appreciated by those skilled in the art.

The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any equivalent changes, modifications and combinations that may be made by those skilled in the art without departing from the spirit and principles of the invention should be considered within the scope of the invention.
