Description

Technical Field

[0001] This invention relates to the technical field of faucets, and more specifically to a countertop mounting structure for a faucet. Background Technology

[0002] In the prior art, Chinese patent application number 202320482485.7 discloses a loosening and tightening structure for tabletop installation, relating to the field of faucet technology. The key points of its technical solution are: it includes a base for fixing the faucet, at least two bolts are movably arranged on the base, and each bolt is threaded with a positioning block. The bolts can circumferentially limit the positioning blocks on adjacent bolts, and the positioning blocks can move along the axial direction of the bolts to abut against the bottom surface of the base. The positioning blocks can circumferentially limit the positioning blocks on adjacent bolts, and the positioning blocks can move along the axial direction of the bolts away from the base. This loosening and tightening structure for tabletop installation provides a large operating space for the user.

[0003] Based on the prior art, it was found that the above structure did not provide a secure fixation for the faucet after installation on a platform. The main reason for this was that the above solution used a structure with two bolts close together. This concentrated the tightening force on the bolts. Although the first and second positioning blocks would open to provide support and tightening, this method still relied on two bolts, resulting in uneven force distribution around the installation ring. This could easily lead to wobbling. After long-term use, the uneven force distribution on the positioning blocks could cause them to deform, greatly reducing the reliability of the fixation. Therefore, the structural strength needs further improvement. Summary of the Invention

[0004] In order to solve the technical problems and shortcomings of the prior art, the present invention provides a countertop mounting structure for a faucet, which can significantly improve the stability and firmness of the operation of the countertop faucet and solve the technical problem of poor stability of the countertop faucet.

[0005] To achieve the above and other related objectives, the present invention adopts the following technical solution:

[0006] A countertop mounting structure for a faucet includes a faucet base, control components symmetrically arranged on both sides of the faucet base, and a limiting rod. The control components include a long bolt, an opening / closing slider, a slide rail nut, an elastic ring, and an anti-loosening nut.

[0007] The faucet base is provided with an elongated hole for mounting long bolts, a guide slope for guiding the sliding of the opening and closing slider, and a clearance groove for assembling the limiting rod.

[0008] The long bolt passes through the first elongated hole, the opening and closing slider, the slide rail nut, the elastic ring, and the second elongated hole on the limiting rod. The lower end of the long bolt is fixed to the anti-loosening nut.

[0009] The sliding block and the slide rail nut slide together and are fitted with the elastic ring to keep the sliding block against the guide slope. When the long bolt rotates, it drives the slide rail nut to rise, and under the action of the guide slope, the sliding block is in the open state.

[0010] When the sliding block is closed, it passes through the mounting hole on the table from top to bottom; when the sliding block is open, it cannot pass through the mounting hole on the table.

[0011] Preferably, the faucet base is provided with four symmetrical guide slopes in pairs. The two guide slopes abut against the two ends of the opening and closing slider respectively. The two ends of the opening and closing slider are symmetrical. The guide slopes have a vertical section, a curved transition section, and a sloping section. The curved transition section is located between the vertical section and the sloping section.

[0012] Preferably, both the opening / closing slider and the slide rail nut are provided with slots, the elastic ring is sleeved in the slots, and the two sliding ends of the opening / closing slider have a vertical surface and an inclined surface.

[0013] Preferably, a pad is fixed to the top surface of the opening and closing slider, and the pad is made of elastic material or has an upper surface with frictional resistance.

[0014] Preferably, the sliding assembly position of the opening and closing slider and the slide rail nut is located at the middle position of the opening and closing slider, and the slot is also located at the middle position.

[0015] Preferably, the limiting rod has symmetrical limiting rings at both ends. The cross-section of the clearance groove allows the limiting rod to pass through in a horizontal and vertical state. When the limiting rod rotates 90 degrees and the limiting rings are in a flat state, the limiting rod is limited on the clearance groove. The two limiting rings are sleeved on the lower end of the long bolt to limit the lower end of the long bolt.

[0016] Preferably, the lower side of the clearance groove is provided with a concave arc surface that matches the shape of the middle part of the limiting rod, and the concave arc surface and the middle part of the limiting rod are interference-fitted to achieve fastening.

[0017] Preferably, the faucet base is provided with at least one water channel. When two water channels are provided, the two water channels are arranged side by side, and space is left on both sides below the faucet base for the assembly of the control components.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This invention features a symmetrical faucet base structure, with the control components positioned symmetrically on both sides of the faucet base. The control components themselves are also symmetrically structured, with the long bolt positioned in the middle of the opening / closing slider. During installation on the table, the opening / closing slider and slide rail nut are initially positioned at the lower end of the long bolt. The opening / closing slider then rests against the slide rail nut, allowing the entire structure to be inserted from top to bottom through the mounting hole on the table. After insertion, a power tool drives the long bolt to rotate, causing the slide rail nut to move upwards along the bolt. Supported by the guide slope, the opening / closing slider slides upwards and outwards simultaneously. When in the open state, the slider is larger than the diameter of the mounting hole, allowing it to rest against the bottom of the table. The long bolt, opening / closing slider, and slide rail nut thus secure the table. The force distribution on the table is symmetrical and balanced, resulting in convenient operation and greater stability after installation.

[0020] 2. In this invention, the guide slope can provide support and sliding for the opening and closing slider, the symmetrical structure can improve the stability of the opening and closing slider and balance the force, and the curved transition section between the vertical section and the slope section can make the opening and closing slider slide more smoothly and expand out.

[0021] 3. The slot design allows the elastic ring to be embedded, avoiding the risk of it falling off. Moreover, the elastic ring's contraction force ensures that the opening and closing slider always stays against the guide slope. The sliding end design of the opening and closing slider provides stable support on the vertical section, smooth sliding on the transition end, and stable sliding on the slope.

[0022] 4. The pad is located at the top of the opening and closing slider, which is used to contact the bottom of the platform, greatly improving friction and stability.

[0023] 5. The sliding assembly is positioned in the middle of the opening and closing slider, and the slot is also located here. This utilizes the elastic contraction of the elastic ring to provide the force, which is on the same horizontal plane as the sliding direction provided by the sliding structure, without misalignment, thus achieving smooth opening and closing action.

[0024] 6. The structure of the clearance groove makes it easy to install the limiting rod. In order to allow the lower end of the long bolt to be initially limited within a small range, the limiting rod is designed with a limiting ring. At this time, the unique assembly method of the limiting ring achieves locking, further improving the reliability of the long bolt during rotation.

[0025] 7. By using a concave arc surface to achieve an interference fit, the limit rod can be positioned, and at the same time, the limit rod and the long bolt limit each other. The limit rod is fitted on the long bolt, and the limit rod cannot rotate on its own.

[0026] 8. The faucet base can be equipped with a water channel to facilitate the connection of water pipes, enabling water flow and providing water to the faucet body on the countertop.

[0027] Other additional advantages and benefits of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0040] Example:

[0041] This invention discloses a countertop mounting structure for a faucet, with reference to... Figure 1 and Figure 2 As shown, the device includes a faucet base 1, control components 2 symmetrically arranged on both sides of the faucet base 1, and a limiting rod 3. This embodiment has two control components 2, each including a long bolt 21, an opening / closing slider 22, a slide rail nut 23, an elastic ring 24, and an anti-loosening nut 25. The faucet base 1 is provided with an elongated hole 11 for mounting the long bolt 21, a guide slope 12 for guiding the opening / closing slider 22, and a clearance groove 13 for assembling the limiting rod 3.

[0042] The long bolt 21 passes through the long slot 11, the opening and closing slider 22, the slide nut 23, the elastic ring 24, and the long slot 31 on the limit rod 3. The lower end of the long bolt 21 is fixed with the anti-loose nut 25. The long bolt 21 can be used with power tools or manual tools (such as an Allen wrench). When the Allen wrench is rotated, the anti-loose nut 25 and the long bolt 21 rotate together.

[0043] The opening / closing slider 22 and the slide rail nut 23 slide and engage with each other, and are fitted with the elastic ring 24. The opening / closing slider 22 and the slide rail nut 23 can slide relative to each other in a nearly horizontal direction. The elastic ring 24 can be made of rubber or a rubber band, etc. Figure 2 As shown, the opening / closing slider 22 and slide rail nut 23 of the control component 2 are in their initial state (closed state). Figure 1 The opening and closing slider 22 and slide rail nut 23 of the control component 2 shown are in the open state (expanded state).

[0044] The elastic ring 24 provides force to keep the opening and closing slider 22 in contact with the guide slope 12. When the long bolt 21 rotates to drive the slide rail nut 23 to rise, the opening and closing slider 22 can slide on the guide slope 12 under the action of the guide slope 12, so that it can move from the initial state to the open state (or switch back and forth). This allows for convenient disassembly and assembly operations.

[0045] Combination Figure 5 As shown, when the sliding block 22 is in the closed state (closed state), it passes through the mounting hole 4 of the platform 5 from top to bottom. When the sliding block 22 is in the open state, it cannot pass through the mounting hole 4 of the platform 5. Therefore, the operation of mounting on the platform is simple and convenient, and the fixing method is more stable.

[0046] Working principle description: The faucet base 1 has a symmetrical structure, and the control component 2 is symmetrically positioned on both sides of the faucet base 1. The control component 2 itself has a symmetrical structure. The long bolt 21 is located in the middle of the opening and closing slider 22. During the tabletop installation operation, the opening and closing slider 22 and the slide rail nut 23 are initially positioned at the lower end of the long bolt 21. At this time, the opening and closing slider 22 is close to the slide rail nut 23, allowing the entire structure to be inserted from top to bottom through the mounting hole 4 on the tabletop 5. After insertion, the power tool drives the long bolt 21 to rotate, thereby opening and closing the slide rail nut 23. 23 moves upward along the long bolt 21. At this time, the opening and closing slider 22 slides upward and outward under the support of the guide slope 12. Thus, when the opening and closing slider 22 is in the open state, it is larger than the diameter of the mounting hole 4, so that it can abut against the bottom of the platform 5. At this time, the long bolt 21, the opening and closing slider 22, and the slide rail nut 23 fix the platform 5. After both control components 2 have completed the tightening operation, the force distribution on the platform 5 is symmetrical and balanced. Therefore, the installation of the above scheme achieves the effect of convenient operation and more solid and stable.

[0047] To further improve the operational reliability of the aforementioned fixed installation on the platform, this design incorporates four symmetrical guide slopes 12 on the faucet base 1. Figure 1 , Figure 2 and Figure 3 The two guide slopes 12 shown abut against the two ends of the opening / closing slider 22, which are symmetrical. The guide slopes 12 have a vertical section 121, a curved transition section 122, and a ramp section 123. The curved transition section 122 is located between the vertical section 121 and the ramp section 123. In this invention, the guide slopes 12 provide support and sliding for the opening / closing slider 22. The symmetrical structure improves the stability of the opening / closing slider 22 and balances the force. The curved transition section 122, located between the vertical section 121 and the ramp section 123, allows the opening / closing slider 22 to slide out more smoothly and steadily.

[0048] Although the elastic ring 24 is elastic, to improve its assembly reliability, both the opening / closing slider 22 and the slide rail nut 23 are provided with a groove 26. The elastic ring 24 is fitted into the groove 26, so that the elastic ring 24 is not easy to disengage from the groove 26, and the assembly is firm. Moreover, the contraction force of the elastic ring 24 can always keep the opening / closing slider 22 against the guide slope 12.

[0049] exist Figure 1-3 As can be seen, the two sliding ends 223 of the opening and closing slider 22 have a vertical surface 221 and an inclined surface 222. Combined with the corresponding guide ramp, the inclined surface 222 is adapted to the slope of the ramp section 123. Thus, the design of the sliding ends 223 of the opening and closing slider 22 can provide stable support on the vertical section 121, slide smoothly on the transition end, and slide steadily on the ramp surface.

[0050] exist Figure 3 As can be seen, a pad 27 is fixed to the top surface of the opening / closing slider 22. The pad 27 is made of an elastic material or has an upper surface with frictional resistance. The material of the pad 27 can be wear-resistant plastic, wear-resistant rubber, etc. The pad 27 is located at the top of the opening / closing slider 22 and is used to contact the bottom of the platform 5, which greatly improves the friction and the fixation and stability.

[0051] The sliding assembly position 7 of the opening and closing slider 22 and the slide rail nut 23 is located in the middle of the opening and closing slider 22, and the slot 26 is also located in the middle. The sliding assembly position is chosen to be in the middle of the opening and closing slider 22, and the slot 26 is also located here. When the elastic ring 24 is assembled on the slot 26, the elastic force of the elastic ring 24 contracts to provide the force, which is on the same horizontal plane as the sliding direction provided by the sliding structure, without misalignment, thus achieving a smooth opening and closing action.

[0052] To prevent excessive wobbling at the lower end of the long bolt 21, symmetrical limiting rings 32 are provided at both ends of the limiting rod 3. However, this makes it impossible for ordinary holes to allow the limiting rings 32 to pass through. Therefore, a clearance groove was designed. Figure 4 The cross-section of the clearance groove 13 allows the limiting rod 3 to pass through in a horizontal position and the limiting ring 32 to pass through in a vertical position. When the limiting rod 3 rotates 90 degrees and the limiting ring 32 is in a flat position, it is limited on the clearance groove 13. The two limiting rings 32 are sleeved on the lower end of the long bolt 21 to limit the lower end of the long bolt 21 within a small range. Figure 4 The limiting rod 3 is in a horizontal position, and the limiting ring 32 is in a flat position. Figure 4 The limiting rod 3 shown in the figure rotates 90 degrees around its own axis to form the vertical state of the aforementioned limiting ring 32.

[0053] The structure of the clearance groove 13 makes it easy to install the limiting rod 3. In order to allow the lower end of the long bolt 21 to be initially limited within a small range, the limiting rod 3 is designed with a limiting ring 32. At this time, the unique assembly method of the limiting ring 32 achieves locking, further improving the reliability of the long bolt 21 during rotation.

[0054] To ensure reliable assembly of the limiting rod 3, a concave arc surface 131 adapted to the shape of the middle part of the limiting rod 3 is provided on the lower side of the clearance groove 13. The concave arc surface 131 and the middle part of the limiting rod 3 are fastened by an interference fit. The interference fit achieved by the concave arc surface 131 allows the limiting rod 3 to be positioned, and at the same time, the limiting rod 3 and the long bolt 21 mutually limit each other. The limiting rod 3 is fitted onto the long bolt 21, and the limiting rod 3 cannot rotate on its own.

[0055] refer to Figure 6It is understood that at least one water passage 14 is provided inside the faucet base 1; this embodiment illustrates two water passages 14. When two water passages 14 are provided, they are arranged side by side, leaving space on both sides below the faucet base 1 for the assembly of the control component 2. Figure 5 As can be seen, the two control components 2 are located on both sides below the faucet base 1.

[0056] Back Figure 1 As can be seen, the faucet base 1 can be equipped with a water channel 14 to facilitate the connection of the water pipe 6, realize water flow, and facilitate the supply of water to the faucet body on the table.

The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations.
