Description

Technical Field

[0001] The utility model relates to the field of sanitary wares, and particularly refers to a double - handle faucet. Background Art

[0002] The double - handle faucet is a common form of faucet, which is widely used in kitchens and bathrooms. Its main structure includes a faucet body and two valve assemblies, and the valve assemblies are respectively installed on both sides of the faucet body. The design of the double - handle faucet enables users to adjust the water temperature by operating the cold and hot water valves respectively, so as to obtain a comfortable water - using experience. The two valve assemblies are respectively connected to the cold and hot water and are connected to the internal channels of the faucet body to guide the water to the water outlet, realizing the function of mixed water outlet.

[0003] The installation of the existing double - handle faucet is rather cumbersome, mainly due to the structural design of the faucet body and the valve assemblies. Generally, threaded pipes are provided at the lower ends of both the faucet body and the valve assemblies. These threaded pipes need to pass through the tabletop, and then nuts are used to clamp and fix them under the tabletop. This installation method requires precise positioning and the operation of screwing the nuts in a narrow space, which undoubtedly increases the installation difficulty.

[0004] The internal structure of the valve assembly is also relatively complex. Generally, it includes a valve seat, a threaded pipe, and an inlet - outlet water pipe. The valve seat, as the core component of the valve assembly, is used to control the flow of cold and hot water. The threaded pipe is connected to the lower end of the valve seat and is responsible for fixing the valve assembly on the tabletop. The inlet - outlet water pipe needs to be inserted into the threaded pipe and connected to the valve seat to ensure the circulation of cold and hot water. Since the inlet - outlet water pipe needs to pass through the threaded pipe and be precisely connected to the valve seat, not only high operation skills are required during installation, but also problems such as loose connection and water leakage are likely to occur, affecting the use effect. Therefore, how to simplify the installation structure of the double - handle faucet and improve the installation efficiency has become a problem that needs to be solved urgently in the existing technology. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome at least one of the above - mentioned deficiencies in the existing technology, and provide a double - handle faucet, which simplifies the installation steps, improves the installation efficiency, and has the beneficial effect of being convenient and fast.

[0006] To solve the above - mentioned technical problems, the utility model provides a double - handle faucet, which includes a water - outlet component and two valve assemblies arranged on both sides of the water - outlet component, and the valve assemblies are respectively fluid - connected to the water - outlet component;

[0011] In a better embodiment, the valve locking assembly includes a sliding block and two support arms rotatably arranged on the sliding block. The rotation centers of the two support arms are offset from their middle positions. A blocking component is arranged at the lower end of the water passage seat. The control rod can drive the sliding block to move up and down along the water passage seat. The two support arms can approach and abut against the blocking component to rotate to a folded state. The two support arms can move away from the blocking component to rotate to an unfolded state. The radial dimension of the two support arms in the unfolded state is larger than the mounting hole of the tabletop.

[0012] In a better embodiment, the sliding track of the valve locking assembly deviates from the axis of the second on-table mounting assembly.

[0013] In a better embodiment, the blocking component includes a base and two blocking inclined walls. The base is arranged at the lower end of the side wall of the water passage seat. The two blocking inclined walls are arranged on both sides of the base to form an accommodating space with the side wall and the base. The sliding block can be located in the accommodating space. When the sliding block moves close to the blocking inclined wall, one end of the support arm in the unfolded state abuts against the blocking inclined wall to be folded and abutted against the blocking inclined wall.

[0014] In a better embodiment, it further includes a pipe assembly that can be inserted into the lower end of the water passage seat and a clamping component. When the pipe assembly is inserted into the lower end of the water passage seat, the clamping component can be inserted and connected to the pipe assembly and the water passage seat.

[0015] In a better embodiment, the second on-table mounting assembly further includes a valve locking assembly. The valve body is provided with a control rod for interlocking with the valve locking assembly. The valve locking assembly is slidably arranged up and down on a side wall of the water passage seat. The control rod can be operated by an external force to drive the valve locking assembly to slide so as to fixedly abut against the lower side of the tabletop;

[0016] Wherein, the clamping member includes a plugging portion and a stop block. The plugging portion is used for plugging into the lower end of the water passing seat. The upper end of the control rod is correspondingly installed on the valve body, the lower end of the control rod is correspondingly installed on the lower end of the water passing seat, and the lower end of the control rod is correspondingly outside the stop block.

[0018] In a better embodiment, a track is formed on the side wall of the water passing seat, and the valve locking assembly slides on the track.

[0019] In a better embodiment, the first on-table mounting assembly includes a mounting seat and a main body locking assembly. The mounting seat is arranged on the upper side of the tabletop. The mounting seat is provided with a mounting control rod for linking the main body locking assembly. The mounting control rod can be operated by an external force to drive the main body locking assembly to fixedly abut against the lower side of the tabletop.

[0020] Compared with the prior art, the technical solution of the present utility model has the following beneficial effects:

[0021] 1. Both the water outlet component and the valve component adopt the on-table mounting method. This design greatly simplifies the installation steps of the traditional faucet. The water outlet component includes the first on-table mounting assembly and the faucet body. The first on-table mounting assembly can be directly fixedly installed from above the tabletop, so that the faucet body is stably installed on the tabletop. This not only reduces the complex operations during installation, but also avoids the nut tightening steps in the narrow space under the tabletop, thereby improving the installation efficiency and reducing the requirements for installation technology.

[0022] For the valve component, the on-table mounting design is also adopted. The valve component includes the second on-table mounting assembly and the valve component. The second on-table mounting assembly can be directly fixedly installed from above the tabletop. This installation method does not require the cumbersome operations of threading the threaded pipe and tightening the nut like the traditional double-handle faucet, thus significantly reducing the installation difficulty.

[0023] In addition, a water passage seat is specially designed in the second on - table mounting component to achieve convenient water connection. The water passage seat is connected to the valve body and extends below the tabletop, forming a water passage inside for connecting the valve body. Due to the existence of the water passage seat, the inlet and outlet water pipes only need to be connected to the water passage seat to complete the water connection, and there is no need to pass through the threaded pipe for precise connection anymore. This design effectively simplifies the installation process of the inlet and outlet water pipes, reduces the risk of water leakage, and at the same time ensures the smooth flow of cold and hot water, improving the practicality and reliability of the product.

[0024] 2. The second on - table mounting component includes a valve body, a water passage seat, and a valve locking component. Among them, the valve locking component is guided through the water passage seat, optimizing the installation process. The valve locking component is installed on one side wall of the water passage seat and can slide up and down along it. A control rod is provided on the valve body for linkage operation of the valve locking component. Through an external force, the control rod can drive the valve locking component to slide up and down, making it fixedly abut against the lower side of the tabletop. The water passage seat not only plays a role in guiding water but also provides a guiding function for the valve locking component, making the sliding and fixing operations of the valve locking component smoother and more accurate, reducing the space occupied between various components in the traditional valve component, thereby reducing the overall volume. This is not only beneficial for installation in a narrow space but also makes the layout of the faucet body and the valve component more reasonable and beautiful, and the locking process is smoother, less likely to get stuck or be installed improperly.

[0025] 3. The sliding trajectory of the valve locking component does not coincide with the axis of the mounting component, avoiding extrusion or interference with the water passage seat and the water passage during installation and locking, ensuring that the water flow channel always remains straight. This deviation design significantly reduces the resistance of the water flow in the channel, avoiding the generation of turbulent flow and noise, thereby enhancing the water - using experience. The non - deviation state of the water passage also ensures more uniform mixing of cold and hot water and does not affect the stability of the outlet water temperature due to the change of the water flow path. When switching between cold and hot water, the water flow is smoother, and users can obtain the expected water temperature more quickly, enhancing the practicality of the product.

[0026] 4. The blocking component includes a base and two blocking inclined walls. The base is arranged at the lower end of the side wall of the water passage seat, and the two blocking inclined walls are located on both sides of the base, jointly forming a receiving space with the side wall and the base. The sliding block can be located within this receiving space. The setting of this receiving space makes the sliding block more compactly arranged on the water passage seat, making full use of the space and reducing the occupation of additional components. This compact design not only reduces the overall size of the valve component but also optimizes the arrangement of internal components, improving the stability of the entire device.

[0027] 5. The clamping piece includes a plug-in part and a stopper, the plug-in part is used to be plugged into the lower end of the water overflow seat, the upper end of the control rod is correspondingly mounted on the valve body, the lower end of the control rod is correspondingly mounted on the lower end of the water overflow seat, and the lower end of the control rod is correspondingly on the outside of the stopper. When the pipe assembly is plugged into the lower end of the water overflow seat, the clamping piece firmly clamps the two. Subsequently, the upper end of the control rod is mounted on the valve body, and the lower end is mounted on the lower end of the water overflow seat, and is matched with the outer side of the stopper. At this time, since the lower end of the control rod is located on the outer side of the stopper, the clamping piece is effectively locked and cannot fall off directly. This structural design has many beneficial effects. First, this combination of plug-in and clamping makes the connection between the pipe assembly and the water overflow seat more stable, preventing the problem of loose connection or falling off due to external force during use. Since the clamping piece is locked by the control rod, even when water flow pressure is generated in the pipeline or the outside is vibrated, the pipe assembly and the water overflow seat can still maintain a stable connection, thereby improving the durability and reliability of the faucet as a whole. Secondly, the design and installation method of the clip also make the assembly and maintenance of the faucet more convenient. The pipe assembly only needs to be plugged into the lower end of the water outlet, then fixed by the clip, and then the control rod is installed to complete the stable connection. This not only simplifies the installation steps, but also when disassembly and maintenance are required, the clip can be released by removing the control rod to separate the pipe assembly and the water outlet, which is convenient for maintenance. In addition, this design also has the function of preventing misoperation. Since the clip is locked by the control rod, the clip can only be removed after the control rod is removed, which effectively prevents the clip from loosening in accidental situations and ensures the safety of the pipeline connection. In general, this structure ensures the tight connection between the pipe assembly and the water outlet by rationally utilizing the cooperation of the clip and the control rod, and improves the installation convenience and use stability of the product.

[0028] 6. The valve body includes a valve cavity, a flange and a force-bearing disc body. The valve cavity is used to receive the valve core. The force-bearing disc body is sleeved on the lower side of the flange. A notch is provided on one side of the flange. The force-bearing disc body is provided with a through hole corresponding to the notch. The upper end of the control rod is correspondingly provided in the notch, and the control rod passes through the through hole. The force-bearing disc body bears the main force, thereby preventing the flange from directly bearing the external force during installation and operation. Since the force-bearing disc body bears most of the mechanical load, the flange itself is not directly subjected to force, which means that the overall strength requirement of the valve body can be reduced. The wall thickness of the valve body can be appropriately reduced, which not only saves materials but also reduces manufacturing costs. BRIEF DESCRIPTION OF THE DRAWINGS
