Description

Technical Field

[0001] This invention relates to the field of installation of washbasins and vegetable basins (washing tubs), and more specifically to a universal quick-install base for sanitary ware. Background Technology

[0002] The mounting base structure of sanitary ware includes a mounting base sleeve and a mounting nut fitted onto the mounting base sleeve. There are generally two types of faucet locking mechanisms on the market: one is a threaded tube with a double-eared nut, and the other is a threaded rod with a washer and a small nut. The locking mechanism is installed under the countertop and behind the sink. Installation requires reaching under the countertop behind the sink and fitting the mounting nut onto the mounting base sleeve. Rotating the mounting nut causes it to move upwards. When the mounting nut engages with the raised edge of the countertop, it clamps onto the edge of the mounting hole in the sink or washbasin countertop, thus positioning the mounting base sleeve on the sink or washbasin countertop.

[0003] Due to the limited space on walls and in the kitchen, there are still several problems with the installation of sinks and washbasins: installation requires bending over and looking up, which is time-consuming and laborious, resulting in low installation efficiency; installation and disassembly under the countertop are difficult, and most installations require professional plumbers; and the drain pipe smells bad when a new faucet is replaced. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a universal quick-install base for sanitary ware, which solves the problems of time-consuming and labor-intensive installation, low installation efficiency, and pungent odor from the drain pipe in the prior art.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A universal quick-install base for sanitary ware includes a spiral tube, an inner tube, and a corrugated spring. The spiral tube has at least one radially spaced groove at its bottom. The corrugated spring is fitted onto a corrugated spring seat and located inside the spiral tube. The corrugated spring seat includes a base body and at least one movable support leg mounted on the base body. The corrugated spring has an outwardly protruding pressure foot, which is fitted onto the outside of the movable support leg and corresponds to the spaced groove of the spiral tube. When the movable support leg is subjected to an outwardly pushing force, it moves outward, causing the pressure foot on the corrugated spring to expand outward, allowing the pressure foot to extend from the spaced groove at the bottom of the spiral tube.

[0007] Furthermore, the movable support leg includes a support rod and a movable head located at the head of the support rod, the movable head being movably positioned relative to the support rod.

[0008] Furthermore, the corrugated spring is provided with a pressure foot, which protrudes outward from the periphery and forms a pressure foot groove at the protrusion.

[0009] Furthermore, the corrugated spring has a corrugated spring portion between adjacent pressure feet, and four pressure feet are radially distributed on the corrugated spring, with a corrugated spring portion between two adjacent pressure feet.

[0010] Furthermore, the locking groove on the solenoid is designed as an L-shaped slotted structure, including a transverse groove in the radial direction and a vertical groove perpendicular to the transverse groove, wherein the vertical groove communicates with the bottom side of the solenoid, and a limiting post protrudes at the position where the transverse groove and the vertical groove meet, so that the presser foot can be limited to the limiting post after being stretched.

[0011] Furthermore, the inner tube includes an inner tube body and a snap-fit ​​support foot located at the bottom end of the inner tube body, which cooperates with the movable support foot. The snap-fit ​​support foot includes a first snap-fit ​​edge and a second snap-fit ​​edge that is inclined toward the inner side of the inner tube relative to the first snap-fit ​​edge. The plurality of snap-fit ​​support feet form a claw-shaped structure.

[0012] Furthermore, the universal quick-release base also includes a base nut, which is threaded onto the outside of the screw tube.

[0013] Furthermore, the base nut also includes an O-ring and a washer. The O-ring is fitted into the lower groove of the base nut, and the washer is fitted into the upper groove of the base nut.

[0014] Furthermore, a lifting collar is provided on the top side of the inner tube, and a small hole is provided on the top side of the inner tube body. The lifting collar is connected to the inner tube body through the small hole.

[0015] Furthermore, the upper part of the solenoid has at least one guide notch.

[0016] Compared with the prior art, the advantages of this invention are:

[0017] (1) This solution changes the installation from under the table to locking installation from the table. The installation on the table is visible from all directions, and there is no need to turn around or bend over, making it convenient to operate.

[0018] (2) This solution can prevent the inhalation of pungent odors from the drain pipe during installation, and the installation process will not get your hands or clothes dirty.

[0019] (3) This solution effectively improves installation efficiency and saves time and labor costs. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0028] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0029] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0030] Please see Figure 1-5A universal quick-release base includes at least a screw tube 20, an inner tube 30, a corrugated spring seat 43, and a corrugated spring 40. The bottom of the screw tube 20 is provided with at least one locking groove 22 along the radial direction. The corrugated spring 40 is sleeved on the corrugated spring seat 43 and placed inside the screw tube 20. The corrugated spring seat 43 includes a base body and at least one movable support foot 41 provided on the base body. The corrugated spring 40 is provided with an outwardly protruding pressure foot 42. The pressure foot 42 is correspondingly sleeved on the outside of the movable support foot 41 and is provided with the locking groove 22 of the screw tube 20. When the movable support foot 41 is subjected to an outwardly supporting force, the movable support foot 41 moves outward, causing the pressure foot 42 on the corrugated spring 40 to expand outward, so that the pressure foot 42 extends out of the locking groove 22 at the bottom of the screw tube 20.

[0031] Specifically, the diameter of the base of the corrugated spring seat 43 matches the inner diameter of the screw tube 20, so that the corrugated spring seat 43 can be firmly set inside the screw tube 20. The movable support leg 41 is relatively movably set on the base, so that the movable support leg 41 can extend outward when subjected to an outward stretching force.

[0032] More specifically, in one embodiment of the present invention, the movable support leg 41 includes a support rod and a movable head 45 disposed at the head of the support rod, wherein the movable head is movably disposed relative to the support rod. Optionally, the movable head 45 is designed as a triangular structure, in which case the triangular structure further serves as a latching mechanism.

[0033] It is also worth noting that when the corrugated spring seat 43 is provided with multiple movable support legs 41, the multiple movable support legs 41 are spaced apart.

[0034] Correspondingly, the corrugated spring 40, fitted onto the corrugated spring seat 43, is an annular structure with an opening, such as... Figure 5 As shown, the opening is not expanded in its natural state, and the corrugated spring 40 is provided with a pressure foot 42. The pressure foot 42 protrudes outward from the periphery and forms a pressure foot groove at the protrusion position. When the corrugated spring 40 is fitted onto the corrugated spring seat 43, the movable support foot 41 is placed in the pressure foot groove. In addition, the corrugated spring 40 is made of elastic material and changes between its original state and its stretched state. The dimensions of the corrugated spring 40 are controlled such that: when the corrugated spring is in its original state, the opening is not open and the pressure foot 42 is placed inside the screw tube 20; when the corrugated spring 40 is in the stretched state, the opening is open and the pressure foot 42 is stretched outward from the transverse groove 23 of the locking groove 22.

[0035] Furthermore, a corrugated spring portion 44 is provided on the corrugated spring 40 between adjacent pressure feet 42. When the corrugated spring 40 is in its original position, the corrugations on the corrugated spring portion 44 are in their natural position. When the corrugated spring 40 is in a stretched state, the corrugations on the corrugated spring portion 44 are stretched, providing the pressure feet 42 with the length to extend outward, thereby controlling the deformation of the corrugated spring 40 and preventing the corrugated spring 40 from not returning to its original position after multiple uses.

[0036] In an embodiment of the present invention, four pressure feet 42 are arranged radially on the corrugated spring, and a corrugated spring portion 44 is provided between two adjacent pressure feet 42.

[0037] In this embodiment, the corrugated spring 40 is an elastic element with several peaks and valleys on a thin metal ring. This product is made of high-quality spring steel 65Mn (60Si2MnA / 50CrVA / 0Cr17Ni7Al / SUS304), which is heat-treated by a specific method and the hardness is generally controlled between HRC44 and 55 depending on the specific situation, and has good elasticity.

[0038] There are many types of components that can be elastically expanded to hold the platen hole. For example, a regular spring or rubber can be replaced at the presser foot 42. However, compared with regular springs and rubber, the corrugated spring 40 has the advantage of small installation space and is suitable for occasions where the load and deformation are not large and the spring stiffness is required to apply axial pressure.

[0039] Furthermore, the upper surface of the corrugated spring 40 has a grid-patterned anti-slip structure.

[0040] The locking groove 22 on the screw tube 20 is designed as an L-shaped slotted structure, including a transverse groove 23 in the radial direction and a vertical groove perpendicular to the transverse groove 23. The vertical groove is connected to the bottom side of the screw tube 20. A limiting post 24 protrudes at the position where the transverse groove 23 and the vertical groove meet. When the pressure foot 42 is stretched, it can be limited to the limiting post 24.

[0041] The inner tube 30 is detachably placed inside the screw tube 20. Correspondingly, the inner tube 30 includes an inner tube body and a locking support 31 located at the bottom end of the inner tube body and engaging with a movable support 41. The locking support 31 includes a first locking edge and a second locking edge that is inclined towards the inside of the inner tube 30 relative to the first locking edge. Multiple locking supports 31 form a claw-like structure. When the inner tube 30 is inserted into the screw tube 20, the locking support 31 of the inner tube 30 applies an outward force to the movable support 41 on the corrugated spring seat 43, thereby causing the pressure foot 42 to protrude from the locking groove 22.

[0042] In one embodiment of the present invention, the diameter of the inner tube 30 body matches the inner diameter of the screw tube 20, the first snap-fit ​​edge is inclined outward relative to the inner tube body, and the snap-fit ​​support foot 31 is movable relative to the inner tube 30 body. At this time, when the inner tube 30 extends into the screw tube 20, the first snap-fit ​​edge always tends to change to its natural state, which will naturally apply an outward force to the corrugated spring 40.

[0043] Additionally, the universal quick-install base also includes a base nut 10, which is threaded onto the outside of the screw tube 20. In an embodiment of the invention, the base nut 10 further includes an O-ring 11 and a washer 12. The O-ring 11 is fitted into a groove in the lower part of the base nut 10 for cushioning and waterproofing. The washer 12 is a flat Teflon washer, fitted into a groove in the upper part of the base nut 10, to ensure smooth installation between the lower end face of the sanitary ware body and the base nut during installation.

[0044] like Figure 2 As shown, there are two types of base nuts 10: one is an exposed base nut 10 that can serve a decorative purpose, and the other is a concealed base nut 10 that is hidden inside the main body of the table. The two types of bases can be selected according to the actual situation of the faucet body on the table. A wrench is used to tighten the base nuts 10 during installation.

[0045] In addition, a lifting collar 32 is provided on the top side of the inner tube 30. The lifting collar 32 facilitates the operator to lift and remove the inner tube 30 from the screw tube 20. Specifically, a small hole is provided on the top side of the inner tube body of the inner tube 30, and the lifting collar 32 is connected to the inner tube body through the small hole. In addition, the small hole serves as a marker to indicate that the inner tube 30 is pressed into the screw tube 20 for alignment.

[0046] like Figure 4 As shown, the upper part of the screw tube 20 has at least one guide notch 21. The base nut 10 is screwed into the upper end of the screw tube 20. The upper end face of the base nut 10 is slightly lower than the upper end face of the screw tube 20 to ensure that after installation, the guide notch 21 at the upper end of the screw tube 20 is exposed and faces directly forward. The small hole of the inner tube 30 is aligned with the guide notch 21 so that when the inner tube 30 is pressed in, the first support foot 31 is exactly aligned with the pressure foot 42 of the corrugated spring 40.

[0047] During installation, first place the threaded tube 20 with the base nut 10 installed into the hole in the platform, ensuring that the locking groove 22 of the threaded tube 20 is located on the lower surface of the platform. Then, place the inner tube 30 into the threaded tube 20. At this time, the inner tube 30 extends the corrugated spring 40 outward, and the pressure foot 42 of the corrugated spring 40 extends out from the locking groove 22, thereby fixing the quick-release base on the platform. Figure 5 As shown, tighten the nut with a wrench, and then attach the faucet to the base nut 10 to quickly and easily install the faucet.

[0048] It is worth mentioning that, since the diameter of the quick-install base is smaller than that of the platen hole, the quick-install base is fixed by the limiting of the pressure foot 42 below, which allows the quick-install base to be easily placed in the platen hole for easy installation. In addition, the inner tube 30 can be inserted into the screw tube without damping, so as to easily and quickly install the quick-install base and solve the technical problems existing in the prior art.

[0049] Furthermore, since the inner tube 30 is placed inside the threaded tube 20, there is no issue of excessive pressure causing the component to break when inserted into the hole of the sanitary ware countertop. Removal is simple; just pull out the lifting collar. This eliminates the difficulty or lack of knowledge about how to remove it. It also avoids the structural features of not knowing when the installation is complete and occupying space within the threaded tube.

[0050] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
