Description

Technical Field

[0001] This invention relates to the field of faucet installation technology, specifically to a quick-release structure for a faucet countertop and a faucet countertop. Background Technology

[0002] The common installation structure of faucets on the market is usually to install them under the countertop and fix them by rotating nuts. However, this installation method is often limited by the shape and space of the installation location such as washbasins and sinks, making installation and maintenance extremely inconvenient. Summary of the Invention

[0003] One object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages that will be described later.

[0004] Another objective of this invention is to provide a quick-assembly and disassembly structure for a faucet countertop. This structure features a fixing block with a limiting groove on the lower connector of the fixing base, which can be housed within the lower connector. A screw with its top end positioned above the countertop is rotatably mounted within the limiting groove. The fixing block is threadedly connected to the screw. Rotating the screw above the countertop allows the fixing block to move up and down along the screw, or rotate with the screw to protrude or retract into the limiting groove. When the fixing block is retracted into the limiting groove, the lower connector can freely pass through the mounting hole in the countertop. When the fixing block and the upper connector clamp the countertop together, the fixing block protrudes from the limiting groove, preventing the lower connector from easily being pulled out of the mounting hole. This allows for convenient assembly and disassembly of the entire structure on the countertop, eliminating the limitations imposed by the shape and space of the installation location (such as a sink or basin) when installing below the countertop.

[0005] To achieve these and other advantages according to the present invention, a quick-release structure for a faucet countertop is provided, comprising:

They 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, and therefore should not be construed as a limitation of this invention.

[0035] In one of the technical solutions, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the present invention provides a quick-release structure for a faucet countertop, comprising:

[0036] The fixing base is composed of an upper connector 2 and a lower connector 11. The upper connector 2 is located on the upper contact surface of the platform 4. The lower connector 11 passes through the mounting hole 18 on the platform 4 and extends downward. A plurality of limiting grooves 12 are provided around the lower connector 11. A screw 6 is rotatably installed in each limiting groove 12. The top end of the screw 6 is located above the platform 4. A fixing block 7 that moves along the screw 6 is screwed onto the screw 6. The fixing block 7 protrudes from the limiting groove 12 and together with the upper connector 2 clamps the platform 4. When the fixing block 7 moves downward to the bottom of the limiting groove 12, the fixing block 7 is housed in the limiting groove 12.

[0037] The quick-release structure for the faucet countertop provided in this technical solution mainly consists of a fixing base that is detachably connected to the countertop 4. The fixing base is formed by connecting an upper connector 2 and a lower connector 11. The upper connector 2 is located on the upper contact surface of the countertop 4 and is used to connect the faucet 1. The lower connector 11 passes through the mounting hole 18 on the countertop 4 and extends downward. The lower connector 11 is provided with multiple limiting grooves 12, which surround the outer periphery of the lower connector. A screw 6 is rotatably installed in each limiting groove 12. The top end of the screw 6 is located above the countertop, and the screw 6 is provided with an obstruction mechanism. The movable fixing block 7 has a threaded hole and is fitted onto the outer circumference of the screw 6 through the threaded hole, with the two connected by threads. The fixing block 7 protrudes from the limiting groove 12 and together with the upper connecting member 2 clamps the table surface 4. That is, the fixing seat is clamped on the table surface 4 by the fixing block 7 and the upper connecting member 2. When the screw 6 is rotated, the fixing block 7 will not rotate synchronously with the screw 6 under the restriction of the limiting groove 12, but will move up and down along the screw 6. When the fixing block 7 moves down to the bottom of the limiting groove 12, the fixing block 7 rotates together with the screw 6 and is stored in the limiting groove 12. In this technical solution, the number of limiting grooves 12 is preferably two, and they are evenly distributed on the outer circumference of the lower connecting member 11, so that when the fixing block 7 and the upper connecting member 2 clamp the table surface 4, the force is even and the structure is more stable and firm.

[0038] The disassembly and assembly method of the quick-release structure for the faucet countertop of the present invention is as follows:

[0039] Disassembly method: When the fixing block 7 and the upper connecting piece 2 clamp the tabletop 4, the installation is complete. At this time, the fixing block 7 protrudes from the limiting groove 12. The worker holds the upper connecting piece 2 with one hand and rotates the top of the screw 6 above the tabletop 4 with the other hand, so that the entire screw 6 rotates. At this time, the fixing block 7 moves downward along the screw 6 under the horizontal limiting action of the limiting groove 12. When the worker feels that the screw 6 is difficult to rotate or cannot rotate, the fixing block 7 moves to the bottom of the limiting groove 12, and the fixing block 7 and the screw 6 have completed synchronous rotation and the fixing block 7 is stored in the limiting groove 12. Then, rotate the other screws 6 so that all the fixing blocks 7 are stored in their corresponding limiting grooves 12. Then, pull the upper connecting piece 2 from the tabletop 4 to move the lower connecting piece 11, so that the lower connecting piece 11 is pulled out from the mounting hole 18 on the tabletop 4, thus completing the disassembly process.

[0040] Installation process: Before installation, rotate screw 6 to house the fixing block 7 in the limiting groove 12. Then, insert the lower connector 11 into the mounting hole 18 of the tabletop 4. The worker holds the upper connector 2 with one hand and rotates the top of screw 6 with the other hand to make the screw rotate. First, the fixing block 7 and screw 6 rotate synchronously and protrude out of the limiting groove 12. Then, under the horizontal limiting action of the limiting groove 12, it moves upward along screw 6 until the fixing block 7 and upper connector 2 clamp the tabletop 4 together. After all the fixing blocks 7 have moved into place, the installation process is complete.

[0041] The present invention has at least the following beneficial effects: A fixing block with a limiting groove that can be housed in the lower connector of the fixing base is provided in the present invention. A screw with its top end located above the countertop is rotatably provided in the limiting groove. The fixing block is threadedly connected to the screw. Rotating the screw above the countertop allows the fixing block to move up and down along the screw, or to rotate with the screw and protrude or be housed in the limiting groove. When the fixing block is housed in the limiting groove, the lower connector can freely pass through the mounting hole of the countertop. When the fixing block and the upper connector together clamp the countertop, the fixing block protrudes from the limiting groove, preventing the lower connector from being easily pulled out of the mounting hole. This allows for convenient assembly and disassembly of the entire structure on the countertop, making disassembly and maintenance more convenient, without being limited by the shape and space of the installation location such as a washbasin or sink when installed below the countertop. The lower connector of the present invention has multiple limiting grooves, i.e., multiple screws and multiple fixing blocks. These multiple fixing blocks and the upper connector together clamp the countertop, further strengthening the connection between the fixing base and the countertop.

[0042] In another technical solution, the quick-release structure for the faucet countertop includes a non-circular connecting groove at the top of the screw. This connecting groove is used to connect the screw to tools such as screwdrivers, facilitating screw rotation.

[0043] In another technical solution, such as Figure 1 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 10 As shown, in the quick-release structure for the faucet countertop, the upper connector 2 is provided with a first limiting hole 21 communicating with the limiting groove 12, and the lower connector 11 is provided with a second limiting hole 22 communicating with the limiting groove 12. The bottom end of the screw 6 passes through the first limiting hole 21, the limiting groove 12, and the second limiting hole 22 in sequence. The screw 6 is provided with a first limiting member 8 and a second limiting member 9. The first limiting member 8 is located at the bottom of the limiting groove 12 and its position is lower than that of the fixing block 7. The second limiting member 9 is located lower than that of the lower connector 11. The first and second limiting members together restrict the vertical position of the screw to prevent it from moving up and down. The first limiting member rotates synchronously with the screw. When the screw is rotated, the fixing block moves downward until it contacts the first limiting member and then stops moving downward. The fixing block continues to move downward, increasing the pressure on the first limiting member and increasing the friction between the fixing block and the first limiting member. This causes the fixing block to move synchronously with the first limiting member, achieving synchronous rotation with the screw and completing the storage of the fixing block. In other words, the first limiting member ensures that the screw and the fixing block can rotate synchronously.

[0044] In another technical solution, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 10 As shown, in the quick-release structure for the faucet countertop, the limiting groove 12 is L-shaped. Both the first limiting hole 21 and the second limiting hole 22 communicate with the vertical groove of the limiting groove 12. When the fixing block 7 moves downwards to the bottom of the limiting groove 12, the fixing block 7 is housed within the horizontal groove of the limiting groove 12. The limiting groove is designed in an L-shape; the horizontal groove accommodates the fixing block, and the vertical groove mainly accommodates the screw and limits the fixing block, allowing it to move up and down along the screw. Compared to a regular rectangle, the L-shaped limiting groove removes less material from the lower connector, making the lower connector's structure more stable.

[0045] In another technical solution, in the quick-release structure for the faucet countertop, the first and second limiting components are retaining rings or locking nuts. Retaining rings and locking nuts are common parts that are easy to obtain and use.

[0046] In another technical solution, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8As shown, the quick-release structure for the faucet countertop also includes a fixing sleeve 5, which is movably sleeved on the outer periphery of the lower connector 11 and located between the countertop 4 and the fixing block 7. The fixing sleeve is provided to increase the thickness of the countertop, preventing it from being easily damaged due to excessive force caused by an excessively thin countertop.

[0047] In this technical solution, a metal washer 16 is provided between the fixing sleeve 5 and the fixing block 7. This distributes the force of the fixing block onto the metal washer, thereby making the fixing sleeve bear the force evenly.

[0048] In another technical solution, such as Figure 2 , Figure 3 , Figure 11 , Figure 12 As shown, in the quick-release structure for the faucet countertop, the lower connector 11 has multiple annular grooves 23 arranged from top to bottom on its outer periphery, and the inner wall of the fixing sleeve 5 has multiple elastic buckles 17 arranged around it. Each elastic buckle 17 is engaged in one of the annular grooves 23. During installation, after the lower connector is inserted into the mounting hole of the countertop, the fixing sleeve is slipped onto the lower connector from the bottom until it is higher than the fixing block. Then, the screw is rotated, and the fixing block moves upward, causing the fixing sleeve to move upward as well. The fixing block and the upper connector together clamp the fixing sleeve and the countertop, thus completing the installation process. The elastic buckles not only allow the fixing sleeve to move from the lower connector but also limit its movement, preventing it from easily falling off the lower connector. During disassembly, the fixing block is first placed in the limiting groove, and then the fixing seat is pulled from the countertop. The pulling force is greater than the elastic force of the elastic buckles, allowing the fixing seat to be pulled out from the fixing sleeve and separated. The fixing seat can then be removed.

[0049] In another technical solution, such as Figure 2 , Figure 3 As shown, in the quick-release structure for the faucet countertop, a washer 15 is provided between the fixing sleeve 5 and the countertop 4, and the washer 15 is coated with adhesive. The washer is a rubber ring, used to increase the sealing performance of the structure; the adhesive coating on the washer makes the connection between the fixing sleeve and the countertop more secure. During installation, the fixing sleeve and washer can be first glued to the mounting holes of the countertop to increase the thickness of the countertop, treating the countertop and the fixing sleeve as a whole, and then the fixing seat, etc., can be installed.

[0050] In another technical solution, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 10 , Figure 13As shown, the quick-release structure for the faucet countertop also includes a faucet 1, which is detachably connected to the upper connector 2. The upper connector 2 has multiple inverted L-shaped locking blocks 19 on its outer periphery. The bottom tube of the faucet 1 has multiple sets of limiting protrusions on its inner wall. Each locking block 19 corresponds to a set of limiting protrusions. Each set of limiting protrusions consists of an upper limiting protrusion 24 and a lower limiting protrusion 25 distributed vertically. The faucet 1 is fitted over the upper connector 2, and the horizontal block of the locking block 19 is engaged between the upper limiting protrusion 24 and the lower limiting protrusion 25 of its corresponding set. The vertical block of the locking block 19 is in contact with the side of its corresponding lower limiting protrusion 25. The faucet 1 and the upper connector 2 are locked together by fixing screws 3.

[0051] In this technical solution, the faucet 1 and the upper connecting part 2 are disassembled and assembled by means of a screw fastener and locked by fixing screws. The specific disassembly and assembly method is as follows:

[0052] Disassembly method: First, remove the fixing screw 3, then rotate the faucet 1 to pull the horizontal block of the locking block 19 out from between the upper limit protrusion 24 and the lower limit protrusion 25 of its corresponding group. At the same time, the vertical block of the locking block 19 separates from its corresponding lower limit protrusion 25. At this time, the limit protrusion is located between two adjacent locking blocks 19. Then move the faucet 1 upward to move the limit protrusion along the space between the two adjacent locking blocks 19 until the faucet 1 separates from the upper connecting piece 2, thus completing the disassembly process.

[0053] Installation method: First, align the bottom pipe opening of the faucet 1 with the upper connector 2, and rotate and adjust the position of the faucet 1 appropriately so that the limiting protrusion corresponds to the space between the two adjacent locking blocks 19. Then, move the faucet 1 downwards until the horizontal block of the locking block 19 corresponds to the space between the upper limit protrusion 24 and the lower limit protrusion 25 of the same group. Then, rotate the faucet 1 so that the horizontal block of the locking block 19 is inserted between the upper limit protrusion 24 and the lower limit protrusion 25 of its corresponding group, so that the vertical block of the locking block 19 fits against the side of its corresponding lower limit protrusion 25. Finally, install the fixing screw 3 to lock the faucet 1 and the upper connector 2 together, thus completing the installation process.

[0054] In this technical solution, the locking block and the protrusion work together to restrict the position of the faucet and prevent the faucet from rotating or moving up and down at will. The fixing screw further consolidates the connection structure between the faucet and the upper connector.

[0055] In this technical solution, the bottom tube of the faucet 1 has an external threaded hole 13 on its wall, and the upper connector 2 has an internal threaded hole 14 corresponding to the external threaded hole 13. Fixing screws 3 are inserted into the external threaded hole 13 and the internal threaded hole 14 to lock the faucet and the upper connector together. In this technical solution, a retaining ring is provided on the outer periphery of the upper connector, and a rubber ring is fitted onto it. The rubber ring is located at the connection between the retaining ring and the bottom tube of the faucet. The rubber ring is used to enhance the sealing of the connection between the faucet and the upper connector.

[0056] In another technical solution, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 9 , Figure 10 As shown, in the quick-release structure for the faucet countertop, both the upper connector 2 and the lower connector 11 have through holes 20 in their middle portions. A connecting hose 10 is inserted into each through hole 20. The top end of the connecting hose 10 is detachably connected to the faucet 1, and the bottom end is detachably connected to the water supply pipe. The detachable connection of the connecting hose to both the faucet and the water supply pipe reduces movement and pulling of the water supply pipe during assembly and disassembly, thus increasing the service life of the water supply pipe.

[0057] In another technical solution, the present invention also provides a faucet countertop, including the quick-release structure for the faucet countertop described in any of the above technical solutions. The countertop is provided with the mounting hole, and the quick-release structure is detachably mounted at the mounting hole. The quick-release structure can be easily disassembled and assembled from above the countertop.

[0058] The number of devices and processing scale described herein are for the purpose of simplifying the description of the invention. Applications, modifications, and variations of the invention will be readily apparent to those skilled in the art.

[0059] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
