Description

Technical Field

[0001] This utility model relates to the field of faucet installation technology, and in particular to a quick-connect device for faucets. Background Technology

[0002] In the field of faucet installation, quick-connect fittings are commonly used components for rapid assembly of faucets to countertops, such as washbasins and worktops. Currently, existing quick-connect fittings for faucets are generally fixed to the countertop using nuts from underneath. This installation method has significant technical drawbacks in practical applications: First, limited operating space makes installation inconvenient. Since the installation operation needs to be completed under the countertop, the area under the countertop is often narrow due to factors such as cabinets, pipe layout, and other equipment. It is difficult for workers to flexibly reach their hands and installation tools to operate accurately, especially during the tightening of nuts, which can easily lead to uneven force and incomplete tightening, affecting the stability of the installation. Secondly, the installation is inefficient and subsequent maintenance is difficult. When fixing nuts under the tabletop, workers need to repeatedly adjust their posture to fit the limited space, which not only increases the installation time but also reduces the overall assembly efficiency. When the device needs to be disassembled for repair or replacement, the operation must also be carried out under the tabletop. If dust, debris, or pipes and other components accumulate in the space under the tabletop for a long time, or obstruct the disassembly operation, it will further increase the difficulty of maintenance and prolong the maintenance time. Furthermore, the installation requires a high level of skill from the installers. Due to the limited field of vision under the countertop, workers cannot clearly observe the specific conditions of the installation area and can only rely on experience and feel. This not only easily leads to installation errors but may also cause accidental collisions and damage to other components under the countertop, such as pipes and wires, increasing installation risks and additional maintenance costs. In summary, the existing quick-connect faucet installation method, which relies on nuts fixed under the countertop, has significant shortcomings in terms of ease of operation, installation and maintenance efficiency, and operational safety. There is an urgent need for a new installation structure that can solve the above problems. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention provides a quick-connect faucet device, which can effectively solve the problems existing in the prior art.

[0004] The technical solution of this utility model is: According to one aspect of the present invention, the device includes: a fixed base for mounting a faucet, a guide sleeve, and a movable block. The fixed base has a cable routing hole. The upper end of the guide sleeve is fixed to the fixed base, and the lower end extends downward toward the fixed base. The movable block has a connecting portion at a position offset from the center of gravity at its upper end. The connecting portion is movable up and down and can be flipped up and down in the guide sleeve. The movable block also has a threaded hole and an abutment surface extending upward from the threaded hole. The device also includes a fastener, which is movable up and down and rotatably disposed inside the guide sleeve. The lower end of the fastener has an external thread section. As the fastener moves down along the guide sleeve, the lower end of the fastener abuts against the contact surface, causing the upper end of the movable block to rotate downwards with the connection part as the fulcrum until the lower end of the fastener is located behind the threaded hole. Then, the fastener rotates relative to the movable block, so that the external thread section connects to the threaded hole, causing the movable block to move upwards.

[0005] Furthermore, the contact surface includes a vertical surface and a beveled surface sequentially from the threaded hole to its upper end.

[0006] Furthermore, the guide sleeve is eccentrically positioned inside the wiring hole.

[0007] Furthermore, the upper outer wall of the guide sleeve is fixed to the inner wall of the wiring hole.

[0008] Furthermore, the outer wall of the upper end of the guide sleeve is welded to the inner wall of the wiring hole.

[0009] Furthermore, the guide sleeve is provided with guide grooves at its front and rear ends, and the movable block is provided with protrusions on both its front and rear sides as the connecting part. The protrusions are connected to the guide grooves in a way that allows them to move up and down and flip up and down. The guide sleeve is provided with openings at its left and right ends to avoid the movable block from flipping.

[0010] Furthermore, the openings at the left and right ends also serve as mounting ports for loading and unloading movable blocks and their protrusions.

[0011] Furthermore, the vertical surface and the oblique surface are connected by a circular arc transition.

[0012] Furthermore, it also includes a sealing ring disposed at the bottom of the mounting base.

[0013] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: Firstly, there's no need to tighten nuts under the countertop; fasteners can be operated solely from above. Workers don't need to reach their hands or tools into the narrow space under the countertop, effectively avoiding obstructions from cabinets, pipes, and other components. This prevents uneven force distribution and incomplete tightening caused by space constraints, significantly improving the flexibility and precision of the installation process. During installation, there's no need to repeatedly adjust posture to fit the space under the countertop, simplifying the process and greatly reducing installation time. For later disassembly and maintenance, simply reverse the fastener to release the fixation; there's no need to clean dust or debris under the countertop or avoid pipe obstructions, reducing maintenance difficulty and time costs. The entire operation is performed from above the countertop, providing a clear view and allowing workers to directly observe the installation area, eliminating reliance on experience or touch and effectively preventing installation errors. Simultaneously, it avoids accidental collisions with pipes, wires, and other components when hands are under the countertop, reducing installation risks and additional repair costs.

[0014] Secondly, the guide sleeve is eccentrically positioned inside the wiring hole, eliminating the need for additional mounting holes on the mounting base. This fully utilizes the internal space of the wiring hole, making the overall structure of the device more compact and reducing the area occupied around the mounting hole on the platform. The welding process allows the guide sleeve to form an integral structure with the inner wall of the wiring hole, resulting in a connection strength far exceeding that of bolted or bonded connections. This allows the device to withstand the forces generated by repeated installation and disassembly over a long period, ensuring that the device will not loosen during long-term use.

[0015] Third, the cooperation between the guide groove and the protrusion can limit the movement trajectory of the movable block, ensuring its stable up-and-down movement and flipping action, and avoiding problems such as deviation and jamming of the movable block during movement; the openings at both ends of the guide sleeve can completely avoid the end structures of the movable block when flipping, preventing the movable block from colliding and interfering with the inner wall of the guide sleeve, and ensuring smooth flipping action.

[0016] Fourth, during installation, the lower end of the fastener needs to smoothly transition from the beveled surface to the vertical surface. If there are sharp corners at the junction of the two planes, the lower end of the fastener may get stuck at the corners, causing the movable block to flip and jam. The rounded transition can reduce the frictional resistance between the fastener and the contact surface, making the movement of the lower end of the fastener from the beveled surface to the vertical surface more continuous, ensuring that the movable block flips stably along the trajectory, and avoiding installation deviations caused by jamming.

[0017] Fifth, the sealing ring is located at the bottom of the mounting base, which can fill the gap between the mounting base and the countertop, effectively preventing water, dust and other impurities from entering the area below the countertop, protecting the pipes, cabinets and other components below the countertop from contamination and corrosion; the sealing ring has a certain degree of elasticity, and when the movable block lifts the mounting base, it can further press the countertop through its own deformation, increasing the friction between the mounting base and the countertop, and improving the overall installation stability.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0021] like Figures 1 to 5 As shown, this solution provides a quick-connect device for a faucet.

[0022] Please see Figures 1 to 5The system includes: a mounting base 1 for installing a faucet (not shown), a guide sleeve 2, and a movable block 3. The mounting base 1 has a wiring hole 13, which, during installation and use, includes, but is not limited to, threading a water pipe and / or electrical wire connecting to the faucet through the wiring hole 13. The upper end of the guide sleeve 2 is fixed to the mounting base 1, and the lower end extends downwards from the mounting base 1. Preferably, the guide sleeve 2 is eccentrically positioned inside the wiring hole 13. More preferably, the outer wall of the upper end of the guide sleeve 2 is fixed to the inner wall of the wiring hole 13. More preferably, the outer wall of the upper end of the guide sleeve 2 is welded to the inner wall of the wiring hole 13. The guide sleeve 2 is eccentrically positioned inside the wiring hole 13, eliminating the need for additional mounting holes on the fixed base 1. This fully utilizes the internal space of the wiring hole 13, making the overall structure of the device more compact and reducing the area occupied around the mounting hole on the platform. The welding process allows the guide sleeve 2 to form an integral structure with the inner wall of the wiring hole 13, resulting in a connection strength far exceeding that of bolted connections and adhesive bonding. This allows the device to withstand the forces generated by repeated installation and disassembly over a long period, ensuring that the device will not loosen during long-term use.

[0023] It also includes a sealing ring 6, which is located at the bottom of the mounting base 1. The bottom of the mounting base 1 has a mounting groove 12 for installing the sealing ring 6. During installation and use, the bottom of the sealing ring 6 abuts against the countertop (not shown). The sealing ring 6, located at the bottom of the mounting base 1, fills the gap between the mounting base 1 and the countertop, effectively preventing water, dust, and other impurities from entering below the countertop, protecting pipes, cabinets, and other components below the countertop from contamination and corrosion. The sealing ring 6 has a certain degree of elasticity; when the movable block 3 lifts the mounting base 1, it can further press the countertop by its own deformation, increasing the friction between the mounting base 1 and the countertop, and improving the overall installation stability.

[0024] Please see Figures 1 to 5The movable block 3 has a connecting part at an upward offset position from the center of gravity. This connecting part is installed on the guide sleeve 2 and can move up and down and flip up and down. The movable block 3 also has a threaded hole 32 and an abutment surface 30 extending from the threaded hole 32 upward. Specifically, the abutment surface 30 includes a vertical surface 302 and a chamfered surface 301 from the threaded hole 32 upward. Preferably, the vertical surface 302 and the chamfered surface 301 are connected by a rounded transition. During installation, the lower end of the fastener 5 needs to smoothly transition from the chamfered surface 301 to the vertical surface 302. If there is an edge at the junction of the two planes, the lower end of the fastener 5 may get stuck at the edge, causing the movable block 3 to flip and jam. The rounded transition can reduce the frictional resistance between the fastener 5 and the abutment surface, making the movement of the lower end of the fastener 5 from the chamfered surface 301 to the vertical surface 302 more continuous, ensuring that the movable block 3 flips stably along the trajectory and avoiding installation deviations caused by jamming. The guide sleeve 2 has guide grooves 21 at its front and rear ends, and the movable block 3 has protrusions 31 on both its front and rear sides, which serve as the connecting parts. These protrusions 31 are movable up and down and can be flipped up and down, connecting to the guide grooves 21. The guide sleeve 2 has openings 22 at its left and right ends to prevent the movable block 3 from flipping. The cooperation between the guide grooves 21 and the protrusions 31 restricts the movement trajectory of the movable block 3, ensuring stable up-and-down movement and flipping, and preventing the movable block 3 from deviating or jamming during movement. The openings 22 at the left and right ends of the guide sleeve 2 prevent the movable block 3 from flipping, avoiding collisions and interference between the movable block 3 and the inner wall of the guide sleeve 2, ensuring smooth flipping. The guide grooves 21 of the guide sleeve 2 are fully enclosed structures with no notches at the top and bottom, thus limiting the movement of the protrusions 31 of the movable block 3.

[0025] Please see Figures 1 to 5 It also includes a fastener 5, preferably a bolt. The fastener 5 is rotatably and vertically disposed within the guide sleeve 2. The lower end of the fastener 5 is provided with an external thread section 51. When the fastener 5 moves down along the guide sleeve 2, the lower end of the fastener 5 abuts against the abutment surface 30, causing the upper end of the movable block 3 to rotate downward with the connecting part as the fulcrum until the lower end of the fastener 5 is located in the threaded hole 32. Then, the fastener 5 rotates relative to the movable block 3, so that the external thread section 51 is connected to the threaded hole 32, causing the movable block 3 to move upward.

[0026] Please see Figures 1 to 5The openings 22 at the left and right ends of the guide sleeve 2 also serve as mounting ports for loading and unloading the movable block 3 and its protrusions 31. The guide sleeve 2 is made of steel, possessing excellent structural strength and slight elastic deformation capability, ensuring stability during long-term use and adapting to the loading and unloading operation of the movable block 3 through the elastic deformation of the edge frame. In this embodiment, the movable block 3 has a cuboid structure, and all four corners of the movable block 3 are chamfered or rounded. This chamfer design reduces frictional interference between the movable block 3 and the openings 22 of the guide sleeve 2 during loading and unloading, improving the smoothness of assembly. Of course, in other embodiments, the guide sleeve 2 can also be cylindrical or other shapes, as long as the movable block 3 can pass through the openings 22 at the left and right ends of the guide sleeve 2. The specific operation process for assembling the movable block 3 into the guide sleeve 2 is as follows: First, adjust the protrusions 31 on both sides of the movable block 3 to a vertical position. Then, using the slight elastic deformation characteristics of the steel material of the guide sleeve 2, insert the movable block 3 into the guide sleeve 2 along the openings 22 at both ends of the guide sleeve 2. After the movable block 3 is fully inserted into the guide sleeve 2, rotate the movable block 3 forward or backward around the axis of the protrusions 31 so that the beveled surface 301 faces upward and the protrusions 31 on both sides are engaged in the corresponding guide grooves 21 at the front and rear of the guide sleeve 2, thus completing the assembly of the movable block 3.

[0027] Working principle: Embed the sealing ring 6 at the bottom of the fixed seat 1 into the mounting groove 12, ensuring that the sealing ring 6 is completely fitted to the groove wall; place the fixed seat 1 above the mounting hole on the table, so that the sealing ring 6 at the bottom of the fixed seat 1 abuts against the edge of the mounting hole on the table; at the same time, the guide sleeve 2 passes through the mounting hole on the table. At this time, the movable block 3, under its own weight, keeps the guide sleeve 2 in a vertical state, and its protrusion 31 can move freely up and down in the guide groove 21 of the guide sleeve 2. The movable block 3 as a whole does not flip over, and the threaded hole 32 is in a ready-to-connect state. Insert the fastener 5 into the guide sleeve 2. As the fastener 5 continues to move downward, its lower end gradually approaches the chamfered surface 301 of the movable block 3. Continuing to move the fastener 5 downward, the chamfered surface 301 is pushed by the lower end of the fastener. Because the protrusion 31 provides a fulcrum for the movable block 3, the upper end of the movable block 3 flips downward about the protrusion 31, while the lower end of the movable block 3 rises upward simultaneously. The openings 22 at both ends of the guide sleeve 2 provide ample space for the movable block 3 to flip, preventing interference between the movable block 3 and the inner wall of the guide sleeve 2. Continuing to move the fastener 5 downward, the lower end of the fastener 5 passes the chamfered surface 301 and contacts the vertical surface 302. Continue pushing the fastener 5 downward until its lower end is completely inside the threaded hole 32 in the middle of the movable block 3. At this point, the downward movement of the fastener 5 stops, the movable block 3 flips to a horizontal state, and the threaded hole 32 and the external thread section 51 of the fastener 5 are coaxially aligned.

[0028] Rotating the fastener 5 causes the external thread section 51 at the lower end of the fastener 5 to engage with the threaded hole 32 of the movable block 3. As the fastener 5 continues to rotate, the external thread section 51 gradually screws into the threaded hole 32. During this process, the fastener 5 is limited by the guide sleeve 2 and cannot continue to move downward. Instead, it drives the movable block 3 to move upward along the guide groove 21 through the threaded transmission. As the movable block 3 moves upward, its upper end gradually approaches the bottom of the tabletop until the upper end of the movable block 3 abuts against the bottom of the tabletop. At the same time, under the upward pulling force of the movable block 3, the fixed seat 1 drives the sealing ring 6 at the bottom to further press against the tabletop surface, thus achieving a firm fixation between the device and the tabletop. Then, the faucet is fixedly installed on the fixed seat 1, and the water pipe, wire, etc. connecting the faucet are passed through the wiring hole 13 of the fixed seat 1 to complete the assembly of the device and the faucet.

[0029] When it is necessary to disassemble the fixed base 1, simply rotate the fastener 5 in the opposite direction to make the external thread section 51 unscrew out of the threaded hole 32; as the threaded engagement is released, the movable block 3, under its own gravity, flips back to its original position around the protrusion 31 as the axis, and its upper end disengages from the bottom of the table; at this time, lift the fixed base 1 upwards to remove the entire device from the table and complete the disassembly. The whole process does not require reaching under the table to operate, which greatly reduces the difficulty of maintenance.
