Description

Technical Field

[0001] The utility model relates to a faucet installation component, in particular to a quick installation structure of a faucet component. Background Art

[0002] A common faucet assembly installed on a countertop, for example, a countertop next to a bathtub, is usually provided with three mounting holes on the countertop, including two side mounting holes and a mounting hole in the middle, so that the faucet assembly can be installed upward from the space below the countertop. In particular, before the faucet assembly is installed, a part of the components or the half set inside the wall is usually installed on the countertop first, and then another part of the components or the half set outside the wall is installed on the half set inside the wall.

[0003] Specifically, the half group inside the wall usually includes a cold water valve group, a hot water valve group and a water outlet base; wherein, the bottom end of the cold water valve group has a cold water inlet pipe, a cold water outlet pipe and a locking ring, and two locking bolts are screwed on the locking ring; the bottom end of the hot water valve group has a hot water inlet pipe, a hot water outlet pipe and a locking ring, and two locking bolts are also screwed on the locking ring; the bottom end of the water outlet base has a mixed water inlet pipe and a locking ring, and the free ends of the mixed water inlet pipe are respectively connected to the cold water outlet pipe and the hot water outlet pipe, and the locking ring is also screwed with two locking bolts. Therefore, the half group inside the wall is roughly an integrated component before installation, and the installer can install the half group inside the wall After a portion of the cold water valve group, the hot water valve group and the water outlet base are extended upward from the relative installation holes on the table top, they are then limitedly installed. For example, a C-shaped buckle is used to buckle on at least one of the cold water valve group, the hot water valve group and the water outlet base from the table top to prevent the half group inside the wall from falling down and leaving the table top, and then subsequent installation operations are carried out. Commonly, a clamping ring can be used to lock the cold water valve group, the hot water valve group and the water outlet base from the table top, and the clamping bolts are tightened. After the fixation is completed, a control handle is installed on the cold water valve group and the hot water valve group, and a water outlet pipe is installed on the water outlet base, etc., thereby completing the installation of the faucet assembly.

[0004] The installation operation of the half set inside the wall often troubles installers. Since the space under the countertop is usually very narrow, and the installer has to hold the half set inside the wall with one hand for alignment and penetration operations, while using the other hand to assemble and fix limiters such as the above-mentioned C-shaped fasteners on the part that penetrates out from above the countertop, the overall installation process is extremely arduous and laborious. Even after the assembly of the limiter is completed, since the limiter only restricts the half set inside the wall from falling down at most and cannot ensure that the half set inside the wall is at a correct height position, that is, it cannot ensure that the penetration height or valve height position of the cold water valve group, hot water valve group, and water outlet base meets the installation requirements. Therefore, the installer still needs to measure the valve height and adjust the above-mentioned compression ring and tightening bolt back and forth to achieve the correct height position. In this way, it also increases the complexity and difficulty of installation, not only affecting the installation efficiency but also making it difficult to achieve correct and precise installation positioning.

[0005] In addition, in some cases, after the half set inside the wall is installed, in order to prevent the half set outside the wall from being damaged by collision during other construction operations, the half set outside the wall is usually not installed immediately, but after other construction operations are completed, the final installation operation is carried out. However, if the half set inside the wall is not properly covered and protected, it is likely to be entered or contaminated by various foreign substances and impurities during other construction operations, which may also affect the installation positioning of the subsequent half set outside the wall. Summary of the Invention

[0006] The main purpose of the present invention is to provide a quick installation structure for a faucet assembly, which can facilitate installers to perform simple and quick installation operations, improve the assembly efficiency and correctness, and can also provide aesthetic decoration or dust-proof effects during the installation process.

[0007] To achieve the above object, the present utility model provides a quick installation structure for a faucet assembly. The faucet assembly can be installed upward from below a tabletop. The tabletop is provided with three installation holes, namely a first side installation hole, a second side installation hole, and a middle installation hole. The faucet assembly includes a cold water valve group, a hot water valve group, and a water outlet base. The cold water valve group can pass upward through the first side installation hole, and has a cold water inlet pipe, a cold water outlet pipe, a first locking ring, and two first tightening bolts screwed on the first locking ring for pressing against the bottom wall surface of the tabletop at the bottom. The hot water valve group can pass upward through the second side installation hole, and has a hot water inlet pipe, a hot water outlet pipe, a second locking ring, and two second tightening bolts screwed on the second locking ring for pressing against the bottom wall surface of the tabletop at the bottom. The water outlet base can pass upward through the middle installation hole, and has a mixed water inlet pipe, a third locking ring, and two third tightening bolts arranged on the third locking ring for pressing against the bottom wall surface of the tabletop at the bottom. The mixed water inlet pipe further has a cold water joint and a hot water joint, which can be respectively connected and fixed to the water outlet ends of the cold water outlet pipe and the hot water outlet pipe.

[0008] At least one pre-installed part, in the shape of a cover, can be pre-screwed and covered on at least one of the tops of the cold water valve group, the hot water valve group, and the water outlet base, and an elastic conical wall is formed at the bottom. The elastic conical wall gradually expands towards the bottom edge and can elastically contract and expand. Accordingly, when the pre-installed part passes upward through at least one of the opposite installation holes on the tabletop along with the faucet assembly, the elastic conical wall at its bottom end can be gradually pressed to elastically contract, allowing it to pass through the installation hole, and elastically expand after completely passing through, so that the bottom edge thereof can abut and be limited on the peripheral wall surface around the top of at least one of the opposite installation holes to prevent the faucet assembly from falling downward and disengaging from the tabletop.

[0009] In the quick installation structure of the faucet assembly, a first screwing part is formed at the passing part where the cold water valve group, the hot water valve group, and the water outlet base pass upward through the respective opposite installation holes. The pre-installed part is formed with a second screwing part for screwing and fixing to the first screwing part.

[0010] In the quick installation structure of the faucet assembly, the cold water valve group has a tubular valve seat and a control valve core installed on the tubular valve seat. One ends of the cold water inlet pipe and the cold water outlet pipe are respectively connected to the bottom part of the tubular valve seat. The first locking ring is screwed on the outer peripheral wall at the bottom of the tubular valve seat. A section of external thread is provided on the control valve core to form the first screwing part. A section of internal thread is provided at the corresponding part of the inner peripheral wall of the pre-installed part to form the second screwing part.

[0011] The quick installation structure of the faucet assembly, wherein the hot water valve group has a tubular valve seat and a control valve core installed on the tubular valve seat; one end of the hot water inlet pipe and the hot water outlet pipe are respectively connected to the bottom end part of the tubular valve seat; the second lock ring is screwed on the outer peripheral wall of the bottom end of the tubular valve seat; a section of external thread is provided on the control valve core to form the first screwing part; a section of internal thread is provided on the relative part of the inner peripheral wall of the pre-installed part to form the second screwing part.

[0012] The quick installation structure of the faucet assembly, wherein the water outlet base has a fixed screw pipe and an adapter inner pipe installed on the fixed screw pipe; one end of the mixed water inlet pipe is connected to the bottom end part of the fixed screw pipe, and the other end is formed with the cold water joint and the hot water joint; the third lock ring is screwed on the outer peripheral wall of the bottom end of the fixed screw pipe; a section of internal thread is provided on the inner peripheral wall of the top end of the adapter inner pipe to form the first screwing part; the pre-installed part has a top wall, a cover part extends downward around the top wall, the elastic conical wall is formed by a part below the cover part, a screw pipe part protrudes downward inside the top wall, and a section of external thread is formed on the outer peripheral wall of the screw pipe part to form the second screwing part.

[0013] For the quick installation structure of the faucet assembly, the bottom edge of the elastic conical wall of the pre-installed part is longitudinally grooved upwards, and an elastically collapsible and expandable elastic piece can be defined between any two adjacent longitudinal grooves.

[0014] Due to the ingenious use of the pre-installed part on at least one of the cold water valve group, the hot water valve group and the water outlet base in the quick installation structure of the present utility model, it can effectively help the installer to simply and quickly operate from under the countertop with one hand or both hands during the initial installation stage, without the need to perform a limiting operation on the countertop synchronously. Therefore, the installation operation procedure is quite simple and fast, and the installation efficiency can be greatly improved.

[0015] Through the design of the specification size of the pre-installed part, after the initial installation operation, the valve height position of the faucet assembly can accurately meet the requirements, without the need for additional and difficult measurement and adjustment procedures, thereby greatly saving the adjustment time and correctness of the valve height.

[0016] Before disassembly, the pre-installed part can also act as a decorative cover or a dust cover, and can particularly effectively prevent various foreign objects and impurities from entering or contaminating the cold water valve group, the hot water valve group or the water outlet base during the installation process.

[0033] Such as Figures 1 to 6As shown, the present utility model provides a first embodiment of a quick installation structure for a faucet assembly. The faucet assembly 1 can be installed upward from below a tabletop 2. The tabletop 2 is provided with three installation holes, namely a first side installation hole 2a, a second side installation hole 2b, and a middle installation hole 2c. The faucet assembly 1 includes a cold water valve group 10, a hot water valve group 20, and a water outlet base 30. The cold water valve group 10 can penetrate upward from the first side installation hole 2a, and has a cold water inlet pipe 11, a cold water outlet pipe 12, a first locking ring 13, and two first tightening bolts 14 screwed on the first locking ring 13 for pressing against the bottom wall surface 2d of the tabletop 2 at the bottom. The hot water valve group 20 can penetrate upward from the second side installation hole 2b, and has a hot water inlet pipe 21, a hot water outlet pipe 22, a second locking ring 23, and two second tightening bolts 24 screwed on the second locking ring 23 for pressing against the bottom wall surface 2d of the tabletop 2 at the bottom. The water outlet base 30 can penetrate upward from the middle installation hole 2c, and has a mixed water inlet pipe 31, a third locking ring 32, and two third tightening bolts 33 provided on the third locking ring 32 for pressing against the bottom wall surface 2d of the tabletop 2 at the bottom. The mixed water inlet pipe 31 further has a cold water joint 311 and a hot water joint 312, which can be respectively connected and fixed to the water outlet ends of the cold water outlet pipe 11 and the hot water outlet pipe 21. Its main improvement lies in:

[0034] At least one pre-installed part 40, in the shape of a cover, can be pre-screwed and covered on at least one of the tops of the cold water valve group 10, the hot water valve group 20, and the water outlet base 30, and an elastic conical wall 41 is formed at the bottom. The elastic conical wall 41 gradually expands towards the bottom edge 42 and can elastically contract and expand.

[0035] Accordingly, when the pre-installed part 40 penetrates upward from at least one of the opposite installation holes on the tabletop 2 along with the faucet assembly 1, as Figure 4 shown, the elastic conical wall 41 at its bottom can be gradually compressed to produce elastic contraction, allowing it to pass through the installation hole, and after completely passing through, it produces elastic expansion, so that its bottom edge can be abutted and limited on the peripheral wall surface 2e of at least one of the opposite installation hole tops, as Figure 5 、 6 shown, to prevent the faucet assembly 1 from falling downward and detaching from the tabletop 2.

[0036] In this embodiment, the pre-installed part 40 is pre-installed at the top part of the water outlet base 30.

[0037] In this embodiment, as Figure 6As shown, a first screwing part 300 is formed at the penetrating part where the water outlet base 30 penetrates upward from the middle mounting hole 2c; a second screwing part 400 is formed on the pre-installed part 40 for screwing and fixing to the first screwing part 300.

[0038] In this embodiment, as Figure 5 , 6 shown, the water outlet base 30 has a fixed screw tube 301 and an adapter inner tube 302 mounted on the fixed screw tube 301; one end of the mixed water inlet pipe 31 is connected to the bottom end part of the fixed screw tube 301, and the other end is formed with the cold water joint 311 and the hot water joint 312; the third lock ring 32 is screwed on the outer peripheral wall of the bottom end of the fixed screw tube 301; a section of internal thread is provided on the inner peripheral wall of the top end of the adapter inner tube 302 to form the first screwing part 300; the pre-installed part 40 has a top wall 401, and a cover part 402 extends downward around the top wall 401. The elastic conical wall 41 is formed by a part below the cover part 402. A screw tube part 403 protrudes downward inside the top wall 401, and a section of external thread is formed on the outer peripheral wall of the screw tube part 403 to form the second screwing part 400.

[0039] In this embodiment, as Figure 2 , 3 shown, a plurality of longitudinal grooves 43 are longitudinally cut upward at the bottom edge 42 of the elastic conical wall 41 of the pre-installed part 40, and an elastic sheet 44 that can be elastically contracted and expanded can be defined between any two adjacent longitudinal grooves 43. It can be easily understood that the elastic sheets 44 can jointly define the elastic conical wall 41.

[0040] It should be particularly noted that before the faucet assembly 1 of this embodiment is installed on the tabletop 2, it is usually pre-assembled together to form an integral component. Therefore, after the pre-installed part 40 is pre-installed on the water outlet base 30, the installer can start the installation from below the tabletop 2. First, only need to align the cold water valve group 10, the hot water valve group 20 and the water outlet base 30 of the faucet assembly 1 with the three mounting holes on the tabletop 2, namely the first side mounting hole 2a, the second side mounting hole 2b and the middle mounting hole 2c, respectively, from the space below the tabletop 2. Then, apply force upward until the pre-installed part 40 that has undergone elastic contraction completely passes through the middle mounting hole 2c and then undergoes elastic expansion. In this way, a snap limit structure similar to a barb can be formed, as Figures 4 to 6 shown, to prevent the faucet assembly 1 from falling downward from the tabletop 2 and detaching from the tabletop 2. Therefore, the installer can perform the installation operation with one hand or both hands from below the tabletop 2, without having to adopt the conventional installation method and having to use another hand to perform the synchronous fixing operation from above the tabletop 2.

[0041] Furthermore, the height dimension of the pre-installed part 40 can be pre-calculated and designed such that after the faucet assembly 1 is initially installed and positioned from below the countertop 2, that is, after the bottom edge 42 of the pre-installed part 40 abuts against and is positioned against the peripheral wall surface 2e at the top of the intermediate mounting hole 2c of the countertop 2, the height positions at which the cold water valve group 10, the hot water valve group 20, and the water outlet base 30 protrude from the respective relative mounting holes of the countertop 2, which can also be referred to as the valve height positions, just happen to conform to the height positions designed originally, without the need for further measurement. Therefore, the installer can then perform the screwing and locking of the first tightening bolt 14, the second tightening bolt 24, and the third tightening bolt 33, as Figure 7 shown, and respectively screw and lock a compression ring 15, 25 on the tops of the cold water valve group 10 and the hot water valve group 20, and thus quickly complete the installation operation in the second stage.

[0042] It can be understood that before performing the installation operation in the next stage, the pre-installed part 40 can be used as a decorative cover or a dust cover. Secondly, the pre-installed part 40 can also be unscrewed and removed, and then a compression ring 34 is screwed and locked on the top of the fixed screw pipe 301, and wait for the installation operation in the third stage.

[0043] The installation operation in the third stage is a common installation step. Briefly, when the pre-installed part 40 is removed and the compression ring 34 is locked, an outlet pipe or an outlet faucet can be installed on the connecting inner pipe 302 of the water outlet base 30 first, so that the mixed water formed by the mutual mixing of cold and hot water in the mixed water inlet pipe 31 can be sent to the outlet pipe or the outlet faucet through the water outlet base 30 to form faucet water output. Additionally, a control handle can be installed on each of the cold water valve group 10 and the hot water valve group 20. In this way, the user can switch and control the cold water flowing from the cold water inlet pipe 11 to the cold water outlet pipe 12 through the control handle, and adjust the magnitude of the cold water output, or switch and control the hot water flowing from the hot water inlet pipe 21 to the hot water outlet pipe 22, and adjust the magnitude of the hot water output. The ratio of the cold water output to the hot water output determines the temperature of the mixed water formed in the mixed water inlet pipe 31.

[0044] As we all know, before the installation of the third stage mentioned above, the faucet assembly 1 has not yet formed a complete faucet assembly, so it is usually simply referred to as the in-wall half set in the industry. The other half set refers to the out-wall half set, that is, the water outlet pipe and the two control handles installed in the third stage. And in this embodiment, by using the pre-installed pre-fitting 40, it is convenient to install the faucet assembly or the above-mentioned in-wall half set simply and quickly on the tabletop 2, so as to facilitate the installation operation of the second stage mentioned above. As for the installation operation of the third stage mentioned above, it is roughly the same as the conventional technology and is not the technical scope that the present utility model intends to protect, so it will not be elaborated here.

[0045] As Figures 8 to 11 shown, the present utility model further provides a second embodiment of a quick installation structure of a faucet assembly. The installation structure of this embodiment is roughly the same as that of the first embodiment, and its main difference lies in:

[0046] The pre-fitting 40 of this embodiment is installed at a different position, that is, it is selected to be installed on at least one of the cold water valve group 10 or the hot water valve group 20. For example, it can be installed on the cold water valve group 10.

[0047] Similarly, for the convenience of installation, the cold water valve group 10 of this embodiment can form a first screwing part 100 at the penetrating part that penetrates upward from the relative installation hole, and a second screwing part 400 is formed on the pre-fitting 40 for screwing and fixing to the first screwing part 100. It can be understood that since the appearance and structure of the cold water valve group 10 are different from those of the water outlet base 30, the appearance and structure of the pre-fitting 40 of this embodiment will also be different from those of the pre-fitting 40 of the first embodiment. The positions and structures of the first screwing part 100 and the second screwing part 400 of this embodiment will also correspondingly change.

[0048] More specifically, the cold water valve group 10 has a tubular valve seat 101 and a control valve core 102 installed on the tubular valve seat 101; one ends of the cold water inlet pipe 11 and the cold water outlet pipe 12 are respectively connected to the bottom end part of the tubular valve seat 101; the first lock ring 13 is screwed on the outer peripheral wall of the bottom end of the tubular valve seat 101; a section of external thread is provided on the control valve core 102 to form the first screwing part 100; a section of internal thread is provided at the relative part of the inner peripheral wall of the pre-fitting 40 to form the second screwing part 400.

[0049] It can be easily understood that when the pre-installed part 40 is selected to be installed on the hot water valve group 20, or when a pre-installed part 40 is installed on each of the cold water valve group 10 and the hot water valve group 20, the structure of the hot water valve group 20 can be designed to be the same as that of the cold water valve group 10, that is, it is also designed with a similar tubular valve seat 201, a control valve core 202 and a first screwing part 200.

[0050] During the installation of this embodiment, the faucet assembly 1 can also be passed upward through each installation hole from below the tabletop 2, so that the pre-installed part 40 installed on at least one of the cold water valve group 10 and the hot water valve group 20 can generate a limiting function after passing through its corresponding installation hole. Similarly, it can prevent the faucet assembly 1 from falling downward and detaching from the tabletop 2. In this way, the installer can perform installation operation steps similar to the above-mentioned second and third stages.

[0051] In order to achieve a better locking and tightening effect, a plurality of washers can also be sleeved on the bottom parts of the tubular valve seats 101, 201 and the fixed screw pipe 301, so that the first tightening bolt 14, the second tightening bolt 24 and the third tightening bolt 33 can first abut against the washers, and then tighten against the bottom wall surface 2d of the tabletop 2 through the washers, thus having a larger contact area and a more evenly stressed tightening and fixing effect.

[0052] As can be seen from the above, the quick installation structure of the faucet assembly of the present utility model has many features and achievable effects:

[0053] First, by cleverly pre-installing the pre-installed part 40 on at least one of the cold water valve group 10, the hot water valve group 20 and the water outlet base 30, it can effectively assist the installation operation in the first stage. In the installation operation of this stage, the installer can operate with one hand or both hands, but at least does not have to synchronously perform the conventional limiting operation on the tabletop 2 with difficulty. In this way, the originally difficult installation operation procedure will become quite simple and easy, and the installation efficiency can also be improved.

[0054] Second, through the design of the specification size of the pre-installed part 40, after the installation operations in the first and second stages, the valve height position of the faucet assembly 1 can accurately meet the requirements without going through additional and difficult measurement and adjustment procedures. In this way, not only a large amount of adjustment time is saved, but also the correctness of the installation position can be ensured.

[0055] Third, before being disassembled, the pre-installed part 40 can also act as a decorative cover or a dust cover. Especially before the installation operation in the third stage, it can effectively prevent various foreign objects and impurities from entering or contaminating the cold water valve group 10, the hot water valve group 20 or the water outlet base 30.

[0056] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
