Description

Technical Field

[0001] This utility model relates to the field of faucet structures. More specifically, this utility model relates to a slab handle structure for a faucet and a faucet itself. Background Technology

[0002] Currently, in most common faucet products on the market, sintered stone is usually used only as a decorative component in the faucet structure. Its connection with the handle base is usually achieved by covering its surface with a metal shell and then fixing it to the handle base. This makes the sintered stone and the handle base non-removable. When you want to DIY different colored sintered stone or when the sintered stone is damaged and needs to be replaced, the existing connection structure between the sintered stone and the handle base cannot meet the above requirements.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0019] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0020] like Figure 1-7 As shown, this utility model provides a slab handle structure for a faucet and a faucet 7, comprising: The handle base 3 has multiple mounting holes 301 through it; The rock slab component is movably mounted on the top of the handle seat 3. The rock slab component includes a rock slab 1 and a support plate 2 located at the bottom of the rock slab 1. The support plate 2 has multiple screw holes 6. Multiple screws 4 correspond one-to-one with multiple screw holes 6 and multiple mounting holes 301. The screws 4 pass through the corresponding mounting holes 301 and are screwed into the corresponding screw holes 6.

[0021] In the above technical solution, the handle base 3 can be made of brass or stainless steel and processed into a cylindrical shape, with three mounting holes 301 through the top; the rock slab component is composed of an artificial stone round plate (rock slab 1) and a 304 stainless steel support plate 2. The bottom of the rock slab 1 can be fixed to the support plate 2 by epoxy resin adhesive. The support plate 2 has three internal threaded screw holes 6 that match the positions of the mounting holes 301; the screw 4 is a stainless steel countersunk screw 4, whose shank diameter is clearance-fitted with the mounting hole 301 (0.1-0.3mm), and the head is designed with an internal hexagonal groove structure. In this technical solution, during installation, the support plate 2 of the rock slab is manually aligned and placed on top of the handle seat 3. After rotating and adjusting until the three sets of screw holes 6 are coaxially aligned with the mounting holes 301, the screws 4 are passed through the mounting holes 301 and screwed into the screw holes 6 in sequence with an Allen wrench and tightened until the head of the screw 4 sinks into the hole. During disassembly, all screws 4 are loosened in the opposite direction and removed. The rock slab can be separated by simply lifting it upwards. The beneficial effects of adopting this technical solution are that the screw 4 connection allows users to quickly disassemble and replace the rock slab, meeting personalized DIY needs; when the rock slab 1 is damaged, only the rock slab part needs to be replaced, shortening the repair time; the three-point screw 4 evenly distributed locking provides high tensile strength, preventing the rock slab 1 from cracking under stress, and the stainless steel material is resistant to moisture and corrosion. In another technical solution, a sinkhole 101 is provided at the bottom of the rock slab 1, and a sinking platform 201 adapted to the sinkhole 101 is provided on the support plate 2. The sinking platform 201 is inserted into the sinkhole 101, and the sinking platform 201 is glued to the inner wall of the sinkhole 101. In the above technical solution, a cylindrical recess 101 can be formed at the bottom of the rock slab 1 by CNC precision machining. The recess 201 of the support plate 2 can be injection molded from POM engineering plastic, and its outer diameter is fitted with the recess 101 with a clearance (0.02-0.05mm on one side). After the sidewall of the recess 201 is coated with epoxy resin, it is vertically inserted into the recess 101 with a resin layer thickness of 0.1-0.2mm. After curing, it forms a permanent bond. The height of the recess 201 is 0.1-0.3mm lower than the depth of the recess 101 to ensure that the resin layer is full. Using this technical solution, during production, the support plate 2 sink 201 is evenly coated with adhesive and then pressed into the sink 101 of the rock slab 1. The adhesive is allowed to cure and solidify to form the rock slab component. During maintenance and replacement, the entire rock slab component can be removed by simply disassembling the screws 4. If it is necessary to separate the rock slab 1 from the support plate 2, the adhesive layer needs to be broken (this can be done by heating the epoxy resin to 150°C with a hot air gun to soften it before prying it off). The beneficial effects of adopting this technical solution are that the adhesive fit between the settling platform 201 and the settling groove 101 eliminates the micro-displacement between the rock slab 1 and the support plate 2, and avoids the decrease in the pre-tightening force of the screw 4 due to long-term use; the gap design ensures uniform coverage of the adhesive layer and prevents moisture intrusion that could lead to delamination; the structure of the settling groove 101 hides the adhesive seam, improving aesthetics, while reducing the risk of cracking of the rock slab 1 due to local stress concentration. In another technical solution, the rock slab 1 is a circular slab, the sink 101 is a cylindrical sink; the handle seat 3 is cylindrical, the top of the handle seat 3 is stepped, the support plate 2 is placed on the step at the lower position, and three mounting holes 301 are provided through the step at the lower position, and the three mounting holes 301 are spaced apart along the circumference of the step at the lower position. In the above technical solution, the rock slab 1 is a circular plate with a cylindrical sink 101 at its bottom; the support plate 2 is designed to be a circular 304 stainless steel plate, and the top is injection molded with POM engineering plastic sink 201 (the diameter is 0.05-0.1mm smaller than the sink 101); the handle base 3 can be made of brass cast into a cylinder, with the top processed into a two-step structure, and three mounting holes 301 are opened through the lower step surface, with the three holes spaced apart along the perimeter of the lower step. During assembly, the support plate 2, recessed platform 201, is glued and pressed into the recessed groove 101 of the rock slab 1 to solidify and form a rock slab component. Then, the rock slab component is placed on top of the handle base 3, so that the support plate 2 is completely in contact with the lower step surface (the gap between the outer wall of the higher step and the side wall of the rock slab 1 is ≤0.3mm). The rock slab component is manually rotated until the three sets of mounting holes 301 are coaxial with the screw holes 6. Finally, the screws 4 are screwed in to fix it. When disassembling, the rock slab component and the handle base 3 can be separated by reversing the operation. When the rock slab component is installed on the handle base 3, the top surface of the rock slab component is flush with the top surface of the handle base 3, which is more aesthetically pleasing. The beneficial effects of adopting this technical solution are that the geometric matching of the circular slab rock plate 1 and the cylindrical handle seat 3 eliminates the restriction on the installation direction, and the user can align the holes by rotating it at will; the stepped structure design makes the top surface of the rock plate 1 flush with the top surface of the handle seat 3 after installation, which is more aesthetically pleasing; the three holes are evenly distributed around the circumference, so that the screw 4 is subjected to uniform force and prevents stress concentration and cracking on one side of the rock plate 1. In another technical solution, the side wall of the sinking platform 201 is provided with at least two elastic claws, and the inner wall of the sinking trough 101 is provided with a corresponding slot, the elastic claws are engaged in the slot, and the gap between the sinking platform 201 and the bottom of the sinking trough 101 is 0.1–0.3 mm. In the above technical solution, the circumferential sidewall of the support plate 2 sinking platform 201 can be fitted with three stainless steel elastic claws (free state outer diameter > sinking groove 101 inner diameter 0.4-0.6mm, not shown in the figure), and the root of the claws is fixed to the sinking platform 201 by laser welding; the circumferential inner wall of the rock slab 1 sinking groove 101 is correspondingly milled with three through slots; when the sinking platform 201 is inserted into the sinking groove 101, the claws are squeezed and elastically contracted, and when the claws move to the slot position, they automatically pop open and lock into the slot, while the bottom of the sinking platform 201 and the bottom surface of the sinking groove 101 maintain a buffer gap of 0.1-0.3mm. When assembling the rock slab, the support plate 2 and the recessed platform 201 are pressed vertically into the rock slab. After the claw contacts the opening of the recessed groove 101, it retracts elastically and slides into the groove wall until the claw and the groove are aligned and "click" to release the lock. When disassembling, a special tool (hook) is required to insert into the groove from the outside of the recessed groove 101, press the claw inward to release the lock, and then push out the support plate 2. The pre-locking function of the claw before the screw 4 is installed can temporarily fix the rock slab and the handle seat 3 to prevent displacement during assembly. The beneficial effects of adopting this technical solution are: the elastic claw mechanical locking provides high tensile strength and good locking effect; the 0.1-0.3mm buffer gap compensates for thermal expansion and contraction deformation, avoiding stress cracking of the rock slab 1; the claw pre-locking function improves the assembly and positioning efficiency of the rock slab parts; and the through-type slot design allows the claw to be maintained without removing screw 4. In another technical solution, the bottom surface of the support plate 2 is provided with two asymmetrical positioning posts 5, and the stepped surface of the handle seat 3 is provided with corresponding positioning holes. After the positioning posts 5 are inserted into the positioning holes, the multiple mounting holes 301 and screw holes 6 are automatically coaxially aligned. In the above technical solution, two stainless steel positioning posts 5 are vertically welded to the bottom surface of the support plate 2; two positioning holes are CNC milled on the low-step surface of the handle seat 3, and the positions of the two holes are perfectly matched with the positioning posts 5; a 15° guide cone angle is machined at the end of the positioning post 5, and the opening of the positioning hole is chamfered by 0.2×45° to assist in the guide; the gap between the post and the hole is 0.025-0.05mm on one side.

[0022] When assembling the rock slab, align the two asymmetrical positioning pins 5 on the bottom surface of the support plate 2 with the positioning holes on the stepped surface of the handle seat 3 and press them down. The pin cone angle and the chamfer of the hole will automatically guide and correct the alignment. When the positioning pin 5 is fully inserted into the positioning hole, the three screw holes 6 of the support plate 2 and the three mounting holes 301 of the handle seat 3 will achieve coaxial self-alignment (deviation ≤ 0.05mm). Then, screws 4 will be screwed in directly to fix it. When disassembling, first remove the screws 4, and then lift the rock slab vertically to make the positioning pin 5 disengage from the positioning hole to complete the separation. The beneficial effects of adopting this technical solution are: the asymmetric double-column design enables foolproof assembly (interference between the column holes and the screw cannot be inserted when mis-assembled at 180°), reducing the error rate; the precision clearance fit ensures automatic alignment of the holes, eliminating the need for manual adjustment; the positioning column 5 bears the shear force, reducing the radial offset of the screw 4 during the pre-tightening process; and the guide cone angle design allows for self-correction of the initial angle deviation of up to ±2.5°. In another technical solution, the mounting hole 301 is a stepped hole, the head of the screw 4 is recessed into the large diameter section of the stepped hole, and a silicone sealing cap 8 is embedded at the opening of the large diameter section. In the above technical solution, the mounting hole 301 of the handle seat 3 is processed into a stepped hole structure (large diameter section at the top and small diameter section at the bottom); the screw 4 is a flat-head hexagonal screw 4, which sinks into the large diameter section after tightening and the top surface is 0.2mm lower than the stepped surface; the silicone sealing cover 8 is made of Shore A50 hardness rubber material injection molded into an umbrella shape, and is pressed into the opening of the large diameter section with an interference of 0.15-0.25mm, and the top surface of the cover is flush with the stepped surface of the handle seat 3.

[0023] When in use, screw the small diameter section of the trapezoidal hole into the screw hole 6 of the support plate 2, and tighten it until the head of the screw 4 is completely sunk into the large diameter section; then, align the silicone sealing cap 8 with the opening of the large diameter section and press it in vertically. After the cap lip deforms elastically, it fits tightly against the hole wall; when the rock plate needs to be replaced for later maintenance, use pointed tweezers to pry out the sealing cap 8 and then operate the screw 4. When reassembling, replace the new sealing cap 8 and press it in (the old cap cannot be reused).

[0024] The beneficial effects of adopting this technical solution are that the countersunk design of screw 4 eliminates the risk of scratches from protrusions, the silicone sealing cap 8 can prevent water vapor / dirt from entering the mounting hole 301, the interference fit improves the water pressure resistance of the sealing cap 8, and the umbrella-shaped structure makes it easy to pry off with tools.

[0025] In another technical solution, a corrugated copper alloy elastic gasket is provided between the support plate 2 and the rock plate 1, the gasket having a crest height of 0.3–0.5 mm and a surface nickel-plated treatment. In the above technical solution, an H62 copper alloy corrugated elastic gasket (thickness 0.4±0.02mm, crest height 0.3-0.5mm, wave pitch 2.0-3.0mm, not shown in the figure) is set between the top surface of the support plate 2 and the bottom surface of the rock plate 1. The gasket surface is chemically plated with nickel; the outer diameter of the gasket is the same as that of the support plate 2, and it is pre-fixed to the top surface of the support plate 2 by high temperature resistant epoxy adhesive.

[0026] During production, nickel-plated gaskets are first bonded to the top surface of support plate 2, and then the assembly is pressed into the sink 101 of rock plate 1 to solidify and form a rock plate component. When assembling handle seat 3, the gasket is compressed (compression amount 0.1-0.3mm) during the tightening of screw 4. The elastic deformation of the wave structure is used to offset the difference in thermal expansion coefficients between rock plate 1 and metal support plate 2. When disassembling the rock plate component, the gasket separates synchronously with support plate 2. If the gasket is plastically deformed, a new part needs to be replaced.

[0027] The beneficial effects of adopting this technical solution are that the corrugated elastic gasket absorbs more than 90% of the assembly stress, preventing the propagation of microcracks in the rock slab 1; the nickel plating layer reduces electrochemical corrosion and meets drinking water contact standards; and the 0.3-0.5mm wave height optimizes the consistency of the screw 4 locking force, extending the service life of the valve core.

[0028] In another technical solution, the top surface of the rock slab 1 is provided with laser micro-etched anti-slip texture. The anti-slip texture is composed of concentric circular grooves with a groove depth of 30–50 μm, a width of 80–100 μm, a spacing of 1.5–2 mm between adjacent grooves, and the grooves are filled with transparent hydrophobic silicone resin. In the above technical solution, the top surface of the rock slab 1 is processed with concentric ring anti-slip texture (not shown in the figure) by ultraviolet laser micro-etching. The groove depth is 35±5μm, the width is 90±10μm, and the center distance between adjacent grooves is 1.8±0.2mm. After etching, the groove is filled with transparent hydrophobic silicone resin. The resin is centrifuged and coated (speed 2500rpm) to fill the groove and overflow 0.5-1μm from the top surface. After curing, it is heat-treated at 160℃ for 2 hours to form a micro-convex wear-resistant hydrophobic layer (the height difference with the surface of the rock slab 1 is ≤0.2μm).

[0029] When the user's finger touches the top surface of the rock slab 1, the groove structure increases the coefficient of friction in the dry state, and the concentric ring pattern guides water droplets to spread radially; in the wet state, the hydrophobic silicone resin layer repels water film to form point contact and maintains the coefficient of friction; after long-term use, when the hydrophobic layer wears down, the residual silicone resin in the groove can still maintain the hydrophobic function.

[0030] The filling greatly enhances wet slip resistance, preventing accidental operation due to slippage; the 30-50μm groove depth balances slip resistance and cleanability; the 1.5-2mm spacing optimizes the tactile feel; the transparent silicone resin maintains the natural texture of the slab 1 and is resistant to detergent corrosion, making it a more suitable anti-slip design for the slab 1 material.

[0031] This utility model also provides a faucet 7, which includes the rock slab handle structure of the faucet.
