Description

Technical Field

[0001] This utility model relates to the field of faucet technology, and in particular to a faucet handle assembly structure. Background Technology

[0002] Most existing faucets use integrated or semi-integrated fixing methods for the handle, decorative parts, and positioning parts. For example, the handle is bound to the base / panel by hidden screws, press fittings, or non-standard connections. After long-term use, when the handle's exterior parts wear down, the plating ages, or the user wants to change the style, it is often necessary to disassemble the panel, base, and even the main valve core together. The disassembly and assembly path passes through the sealing interface, and the seal can be damaged if not handled carefully. Moreover, the hidden fasteners are limited by space and angle, making operation inconvenient. This makes it difficult to meet the need to "replace only the handle body," resulting in high maintenance costs, long water outage times, and difficulty in ensuring aesthetic consistency.

[0003] Even though some solutions claim to support replacement, their transmission often relies on single-point dowels / pins, resulting in small mating surfaces and increased backlash after wear. Positioning is mostly unidirectional or single-point limiting, making it difficult to maintain consistent handle height with the reference surface after repeated assembly. Furthermore, the coupling between the seal and the load-bearing interface means that repeated disassembly and assembly can easily damage the metal surface and induce leakage. Overall, existing structures lack a combined solution that allows for independent disassembly and replacement of the handle assembly while maintaining assembly reference and sealing integrity without affecting the main valve core and pipeline connections.

[0004] Furthermore, the existing head handle mounting structure has the following drawbacks in the prior art:

[0005] 1. The handle and panel need to be separated, and the panel is much larger than the handle, which compromises the aesthetics;

[0006] 2. The handle and panel are matched one-to-one with the main body. The handle must be confirmed when purchasing, and the style cannot be changed later.

[0007] 3. The panel is not sealed to the wall, and surface water can easily seep into the wall, affecting its lifespan and causing it to smell and mold.

[0008] 4. The depth at which the faucet body is embedded in the wall during installation will affect the distance between the panel and the handle, resulting in a significant impact on both operability and aesthetics.

[0009] 5. The gaps between the panel, handle, wall, or countertop are obvious, making them difficult to clean and prone to trapping dirt. Utility Model Content

[0010] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a faucet handle assembly structure.

[0011] To achieve the above objectives, the following solution is adopted:

[0012] A faucet handle assembly structure, the structure comprising:

[0013] The handle body includes a housing, a base, and a fixing connector. A wear-resistant pad is provided between the housing and the base. The fixing connector passes through the base and is threaded to the inside of the housing. A wear-resistant ring is provided between the fixing connector and the base. A toothed sleeve is provided in the base for limiting. A through threaded hole is provided on one side of the base and a bolt is installed in the threaded hole.

[0014] A fixing seat, one end of which is for insertion into a mounting hole in a mounting surface, has an internal thread, and has a circumferentially arranged limiting groove that can fit tightly against the bottom and edge of the base to mate with the bolt;

[0015] The faucet body has a threaded tube that mates with the internal thread and a valve core rod disposed in the threaded tube for switching water distribution or temperature control during rotation. The shape of the valve core rod mates with the toothed sleeve. When the handle, the fixing seat, and the faucet body are installed from top to bottom, the fixing seat is fixed to the faucet through the threaded tube, the handle is limited vertically by the bolt and the limiting groove, and the valve core rod is inserted into the toothed sleeve and rotates with the toothed sleeve.

[0016] Furthermore, a first rubber ring is provided between the fixed joint and the base.

[0017] Furthermore, a second rubber ring is also provided between the fixing base and the mounting surface.

[0018] Furthermore, the inner wall of the fixed joint, the outer and inner walls of the sleeve teeth, and the outer wall of the valve core rod are all radially provided with tooth grooves.

[0019] Furthermore, the outer shell surface is provided with anti-slip grooves.

[0020] Furthermore, the bottom of the fixing joint protrudes outward, which enables the positioning of the base.

[0021] Furthermore, the top of the fixing seat has a positioning groove for positioning the bottom of the base.

[0022] Furthermore, the bottom of the fixing base extends downward and inserts into the mounting hole of the mounting surface.

[0023] Furthermore, the bottom of the threaded tube is confined within the faucet and is threadedly connected to the inner wall of the faucet.

[0024] By adopting the above solution, the beneficial effects of this utility model are:

[0025] This utility model employs a layered connection of "handle body (outer shell / base / fixed connector) - fixed seat - faucet body". The base has a through-threaded hole on its side, and the bolt engages with the circumferential limiting groove on the edge of the fixed seat to form a composite limiting mechanism both vertically and circumferentially. The fixed seat mates with the threaded tube of the faucet body, achieving axial tension from the inside out. Replacement is achieved simply by loosening the side bolts and releasing the limiting relationship between the handle body and the fixed seat, allowing the handle body and base to be removed and replaced as a whole without disassembling the threaded connection between the fixed seat and the body. Structurally, this solves the pain point of handles being unable or difficult to replace, significantly reducing maintenance workload and improving on-site adaptability and ease of replacement.

[0026] To ensure repeatability and long-term stability of replacement, wear-resistant pads between the outer shell and the base, and wear-resistant rings between the fixed connector and the base, are used to share the wear from relative movement and compression. The first rubber ring between the fixed connector and the base, and the second rubber ring between the fixed seat and the mounting surface, form an independent sealing path, ensuring that the operation of replacing the handle body does not cross the main sealing interface, reducing the risk of leakage. The inner toothed sleeve of the base matches the shape of the valve core rod, and radial toothed grooves are provided on the inner wall of the fixed connector, the inner and outer walls of the toothed sleeve, and the outer wall of the valve core rod, providing tooth surface meshing transmission with a large contact area, ensuring that there is no obvious backlash in torque transmission before and after replacement. The assembly height is kept consistent with the constraint of the limiting groove and the bolt, thereby achieving replaceability while maintaining the stability of the opening and closing feel and the water distribution positioning.

[0027] Furthermore, this utility model also has the following advantages:

[0028] 1. The handle and panel are integrated, which is both beautiful and simple;

[0029] 2. The handle, panel and body can be freely matched. That is, when matching the handle, the body can be installed and the ceramic can be applied before making the selection. After using it for a period of time, the style can also be changed at will.

[0030] 3. The handle includes a sealing ring, which is pressed tightly onto the tile surface via a threaded connection to ensure that surface water cannot leak into the wall;

[0031] 4. During installation, the depth of the faucet body embedded in the wall does not affect the distance between the panel and the handle. The distance between the panel and the handle can remain constant, and the operability and aesthetics remain constant.

[0032] 5. The handle and panel are integrated and threaded together to press firmly against the wall or countertop, with no obvious gap between them, making it easy to clean and preventing dirt from accumulating. Attached Figure Description

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Reference Figures 1 to 5 As shown, this utility model provides a faucet handle assembly structure, the structure comprising:

[0042] The handle body, handle 1 includes a housing 11, a base 13 and a fixing joint 17. A wear-resistant pad 12 is provided between the housing 11 and the base 13. The fixing joint 17 passes through the base 13 and is threadedly connected to the inside of the housing 11. A wear-resistant ring 15 is provided between the fixing joint 17 and the base 13. A toothed sleeve 16 is provided in the base 13 for limiting. A through threaded hole 131 is provided on one side of the base 13 and a bolt 2 is installed in the threaded hole 131.

[0043] The fixing seat 3 has one end for insertion into the mounting hole of the mounting surface 5, and has internal threads, and has a circumferentially arranged limiting groove 32 that can fit tightly against the bottom and edge of the base 13 to mate with the bolt 2.

[0044] The faucet 4 has a threaded tube 41 that mates with the internal thread and a valve core rod 42 set in the threaded tube 41 for switching water distribution or switching temperature control when rotating. The shape of the valve core rod 42 matches the toothed sleeve 16. When the handle 1, the fixing seat 3 and the faucet 4 body are installed from top to bottom, the fixing seat 3 is fixed to the faucet 4 through the threaded tube 41, the handle 1 is limited vertically by the bolt 2 and the limiting groove 32, and the valve core rod 42 is inserted into the toothed sleeve 16 and rotates with the toothed sleeve 16.

[0045] A first rubber ring 14 is also provided between the fixed joint 17 and the base 13.

[0046] The mounting base 3 and the mounting surface 5 are also provided with a second rubber ring 31.

[0047] The inner wall of the fixed connector 17, the outer and inner walls of the sleeve teeth, and the outer wall of the valve core rod 42 are all radially provided with tooth grooves.

[0048] The outer casing 11 has anti-slip grooves on its surface.

[0049] The bottom of the fixed connector 17 protrudes outward, which enables it to position the base 13.

[0050] The top of the fixed base 3 has a positioning groove for positioning the bottom of the base 13.

[0051] The bottom of the mounting base 3 extends downward and inserts into the mounting hole of the mounting surface 5.

[0052] The bottom of the threaded tube 41 is confined within the faucet 4, and it is threadedly connected to the inner wall of the faucet 4.

[0053] Working principle:

[0054] During installation, one end of the fixing seat 3 is inserted into the mounting hole of the mounting surface 5, and its internal thread mates with the threaded tube 41 of the faucet body 4. After tightening, the fixing seat 3 is pulled from the inside to the outside by the threaded tube 41 to fit against the mounting surface 5, achieving axial positioning; the limiting groove 32 circumferentially provided on the edge of the fixing seat 3 mates with the bolt 2 in the through threaded hole 131 on the side of the handle 1 base 13 to fix it, stabilizing the assembly height and concentricity of the handle 1.

[0055] In use, rotating the handle 1 drives the main valve core rod 42 through the plastic toothed sleeve 16 to switch the faucet on / off to adjust the temperature or switch the water distribution. The wear-resistant pad 12 and wear-resistant ring 15 ensure that there is no friction when the handle 11 rotates, the first rubber ring 14 ensures that the handle 1 does not wobble when it rotates, and the toothed sleeve 16 ensures that the handle 1 does not have any free rotation or play when it rotates. The base 13 is fixed to the fixed seat 3 by bolts 2 and fits against the surface of the wall or countertop 5, which serves to fix the handle 1 and its outer shell 11 to keep them tightly attached to the wall or countertop 5 when they rotate.

[0056] When the gear sleeve 16 is driven to rotate, it drives the valve core rod 42 that it mates with to rotate, thereby completing the passage switching inside the valve core and realizing the functions of water distribution or temperature regulation. Among them, the radial tooth grooves on the inner wall of the fixed joint 17, the inner and outer walls of the gear sleeve 16 and the outer wall of the valve core rod 42 form a spline meshing surface, which increases the effective contact area and friction coefficient, ensures reliable torque transmission and suppresses backlash and slippage.

[0057] The wear-resistant pad 12 between the outer shell 11 and the base 13, and the wear-resistant ring 15 between the fixed joint 17 and the base 13, bear the relative sliding and axial pressing contact during the rotation of the handle 1, reducing direct wear of metal parts and maintaining a stable rotation feel. The first rubber ring 14, located between the fixed joint 17 and the base 13, is compressed by the thread preload to form a seal on the handle 1 side, making the rotation process more stable; when the second rubber ring 31 is provided, it is located between the fixed seat 3 and the mounting surface 5, and is pressed by the threaded tube 41 to form a seal on the main body side. The dual sealing path maintains the isolation between the water circuit and the outside world under the conditions of handle 1 rotation and long-term use, reducing the risk of leakage and seepage.

[0058] When the handle 1 needs to be replaced, simply loosen the bolt 2 on the side of the base 13, allowing the bolt 2 to exit the circumferential limiting groove 32 of the fixing seat 3. The handle 1 body, along with the base 13 and the fixing connector 17, can then be removed from top to bottom. The threaded connection between the fixing seat 3 and the faucet body 4 does not need to be disassembled, and the sealing interface on the body side remains undisturbed. When replacing the handle 1, reassemble it in the reverse order, inserting the valve core rod 42 into the toothed sleeve 16 and engaging it. Then, re-insert the bolt 2 into the circumferential limiting groove 32 of the fixing seat 3 and tighten it to restore the upper and lower limits and reference. The above process relies on wear-resistant parts to share wear and rubber ring sealing to ensure that the handle 1 maintains reliable transmission, consistent assembly height, and complete sealing even after repeated replacements.

[0059] This utility model employs a layered connection of "handle 1 body (outer shell 11 / base 13 / fixed connector 17) - fixed seat 3 - faucet 4 body". The base 13 has a through threaded hole 131 on its side. The bolt 2 engages with the circumferential limiting groove 32 on the edge of the fixed seat 3 to form a composite limiting mechanism in both the upper and lower and circumferential directions. The fixed seat 3 is matched with the threaded tube 41 of the faucet 4 body to achieve axial tension from the inside out. During replacement, only the side bolt 2 needs to be loosened and the limiting relationship between the handle 1 body and the fixed seat 3 needs to be released. The handle 1 body, along with the base 13, can then be removed and replaced as a whole without disassembling the threaded connection between the fixed seat 3 and the body. Structurally, this solves the problem of the handle 1 being unable or difficult to replace, significantly reducing maintenance workload and improving on-site adaptability and ease of replacement.

[0060] To ensure repeatability and long-term stability of replacement, the wear-resistant pad 12 between the outer shell 11 and the base 13, and the wear-resistant ring 15 between the fixed joint 17 and the base 13, are used to share the relative movement and compression wear. The first rubber ring 14 between the fixed joint 17 and the base 13, and the second rubber ring 31 between the fixed seat 3 and the mounting surface 5 form an independent sealing path, so that the operation of the replacement handle 1 body does not cross the main sealing interface, reducing the risk of leakage. The inner toothed sleeve 16 of the base 13 is shaped to match the valve core rod 42, and the inner wall of the fixed joint 17, the inner and outer walls of the toothed sleeve 16, and the outer wall of the valve core rod 42 are all provided with radial toothed grooves to provide tooth surface meshing transmission with a large contact area, ensuring that there is no obvious backlash in the torque transmission before and after replacement. The assembly height is kept consistent with the constraint of the limiting groove 32 and the bolt 2, so as to maintain the stability of the opening and closing feel and water distribution positioning while achieving replaceability.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
