Description

Technical Field

[0001] This utility model relates to the field of faucet assembly technology, specifically a valve faucet assembly that facilitates valve core replacement. Background Technology

[0002] In daily life and industrial scenarios, valves and faucets are key components for controlling the flow of fluids. Their applications cover multiple fields such as home kitchens and bathrooms, public facilities, and industrial pipelines. As users' demands for product convenience and durability increase, the structural design of faucets has been continuously optimized, from early cast iron materials to today's copper alloy and stainless steel materials, from single right-angle shapes to diverse curved spouts, and in terms of function, it has also evolved from simply passing water to composite functions such as water saving, constant temperature, and filtration.

[0003] As the core component of a faucet, the valve core directly affects the smoothness of operation, sealing performance, and service life. The rationality of its installation structure has become an important indicator for measuring the overall quality of the faucet. Most existing faucet valve cores are of the ceramic valve core or stainless steel ball valve core. Among them, the ceramic valve core is widely used because of its good sealing performance, wear and corrosion resistance, and moderate cost. This type of valve core is usually composed of upper and lower ceramic discs, valve stem, and housing. By rotating the valve stem, the ceramic discs slide relative to each other, realizing the opening and closing of water flow and the regulation of flow.

[0004] However, existing faucet components often require specialized tools, such as wrenches, needle-nose pliers, and screwdrivers, to remove the gland or bolts when replacing the valve core. Furthermore, the clearance between the valve core and the cavity wall is small, making it prone to jamming due to scale buildup after prolonged use. Disassembly requires significant external force, which is not only physically demanding but may also damage the valve core or faucet cavity due to improper operation. In addition, ordinary users lack the professional experience and tools to accurately align the valve core installation angle, easily leading to problems such as leaks and stuck switches after installation, severely impacting replacement efficiency and user experience. Therefore, a valve faucet component that facilitates valve core replacement is proposed. Summary of the Invention

[0005] Therefore, the purpose of this utility model is to provide a valve faucet assembly that facilitates valve core replacement, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a valve faucet assembly that facilitates valve core replacement, comprising an installation cavity, wherein a clamping mechanism is fixedly installed on the side wall of the installation cavity for clamping the side wall of the valve core, and an installation cover is threadedly connected to the upper end of the installation cavity;

[0007] The clamping mechanism includes a clamping block and a spring plate, wherein one end of the spring plate is fixedly installed on the side wall of the mounting cavity, and the protruding part of the spring plate abuts against the clamping block to provide elastic force for the clamping block. The clamping block is fixedly connected to the side wall of the mounting cavity through a telescopic structure to fix the clamping block.

[0008] A collar is fitted on the valve core, and a positioning block is fixedly connected to one side of the collar. A pressure block is fixedly connected to the inner wall of the mounting cover for axial fixation of the valve core.

[0009] By adopting the above technical solution, the clamping mechanism and the mounting cover work together to allow users to replace the valve core without professional tools and skills. The spring plate and the clamping block work together to allow the clamping block to automatically reset when the valve core is removed. When the valve core is installed, the rebound force generated by the spring plate is transmitted to a uniform radial clamping force through the clamping block, thereby firmly fixing the valve core and preventing it from loosening or shifting under water pressure.

[0010] Furthermore, the telescopic structure includes a fixed block and a telescopic plate, wherein the telescopic plate is fixedly installed on the outer wall of the clamping block, and the other end of the telescopic plate is slidably connected to one end of the fixed block, and the other end of the fixed block is fixedly installed on the side wall of the mounting cavity.

[0011] By adopting the above technical solution, the limiting guidance of the fixed block and the telescopic plate ensures that multiple clamping blocks move smoothly in the radial direction, avoiding skewing caused by uneven spring force, keeping the installation cavity channel regular, and facilitating the smooth insertion of new valve cores.

[0012] Furthermore, multiple sets of the clamping mechanism are fixedly installed on the side wall of the mounting cavity, and each set of clamping mechanism has two sets of telescopic structures fixedly installed on its side wall.

[0013] By adopting the above technical solution, multiple clamping mechanisms apply radial clamping force synchronously from multiple directions on the valve core sidewall, making the valve core subjected to uniform force, thereby avoiding skewing caused by unilateral force and significantly improving the stability of valve core installation.

[0014] Furthermore, the inner diameter of the collar is larger than the inner diameter of the pressure block, and the pressure block has an L-shaped cross-section. The pressure block works in conjunction with the collar. When the collar is installed on the valve core, the edge of the pressure block is located within the installation seam between the collar and the valve core, which is used to fix the valve core and the collar.

[0015] By adopting the above technical solution, through the cooperation of the collar and the pressure block, the pressure block transmits axial pressure to the collar and the valve core after the mounting cover is installed, thereby axially fixing the valve core.

[0016] Furthermore, the inner side of the positioning block is fixedly connected with a protrusion corresponding to the outer surface of the valve core, and the length of the positioning block is consistent with the notch length of the clamping block, which is used to accurately align the valve core and the inlet and outlet ports at the bottom of the mounting cavity.

[0017] By adopting the above technical solution, the valve core angle is precisely aligned through the dual positioning of the notch and notch of the positioning block and clamping block, the protrusion and the groove on the outer surface of the valve core, ensuring that the inlet and outlet of the valve core at the bottom are completely matched with the inlet and outlet of the installation cavity at the bottom.

[0018] Furthermore, the top of the clamping block is designed with a slope to guide the valve core along the side wall of the clamping block into the mounting cavity.

[0019] By adopting the above technical solution, the inclined surface design reduces the resistance to insertion and achieves precise guidance, allowing users to slide naturally into the installation cavity along the inclined surface without alignment, further improving the convenience of installation operations.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention, through the cooperation of a clamping mechanism and a mounting cover, allows users to replace the valve core without specialized tools or skills. Users simply rotate and remove the mounting cover to pull out the valve core. The clamping block automatically returns to its axial position under the elastic force of a spring, and the telescopic plate extends synchronously to stabilize the clamping block, quickly opening the mounting cavity channel for easy installation of the new valve core. During installation, the dual positioning of the positioning block and the notches and protrusions of the clamping block, along with the grooves on the outer surface of the valve core, ensures precise alignment of the valve core angle, guaranteeing a perfect match between the inlet / outlet at the bottom of the valve core and the inlet / outlet at the bottom of the mounting cavity. When the clamping block is engaged with the inclined guide surface at the top, insertion is easily completed. At this time, the clamping block is squeezed, causing the telescopic plate to contract. The spring plate deforms, stores potential energy, and converts it into a uniform radial clamping force, thus achieving a stable fixation of the valve core. Finally, the pressure block of the installation cover is inserted into the gap between the collar and the valve core, forming an axial fixation to prevent displacement. The overall design simplifies the operation steps, allowing ordinary users to complete the replacement. At the same time, the dual positioning and bidirectional fixing structure ensures the accuracy of valve core installation and stability during use, effectively solving the problems of complicated valve core replacement and easy leakage in traditional faucets.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] Example 1

[0031] A valve faucet assembly that facilitates valve core replacement, such as Figure 1-5 As shown, it includes an installation cavity 2, a clamping mechanism is fixedly installed on the side wall of the installation cavity 2 for clamping the side wall of the valve core 3, and an installation cover 1 is threadedly connected to the upper end of the installation cavity 2. Through the cooperation of the clamping mechanism and the installation cover 1, the user can replace the valve core 3 without professional tools and skills.

[0032] The clamping mechanism includes a clamping block 23 and a spring plate 24. One end of the spring plate 24 is fixedly installed on the side wall of the mounting cavity 2, and the protruding part of the spring plate 24 abuts against the clamping block 23 to provide elastic force for the clamping block 23. Through the cooperation of the spring plate 24 and the clamping block 23, the clamping block 23 can automatically reset when the valve core 3 is removed. When the valve core 3 is installed, the rebound force generated by the spring plate 24 is transmitted into a uniform radial clamping force through the clamping block 23, thereby firmly fixing the valve core 3 and preventing it from loosening or shifting under water pressure impact. The clamping block 23 is fixedly connected to the side wall of the mounting cavity 2 through a telescopic structure to fix the clamping block 23.

[0033] A collar 12 is fitted on the valve core 3, and a positioning block 121 is fixedly connected to one side of the collar 12. The positioning block 121 makes it easier to adjust the angle of the valve core 3. A pressure block 11 is fixedly connected to the inner wall of the mounting cover 1 for axial fixation of the valve core 3.

[0034] Please see Figure 1-5The telescopic structure includes a fixed block 21 and a telescopic plate 22. The telescopic plate 22 cooperates with the fixed block 21 to form a fixed support structure for the clamping block 23. The telescopic plate 22 is fixedly installed on the outer wall of the clamping block 23, and the other end of the telescopic plate 22 is slidably connected to one end of the fixed block 21. The other end of the fixed block 21 is fixedly installed on the side wall of the mounting cavity 2. Through the limiting guidance of the fixed block 21 and the telescopic plate 22, it is ensured that the multiple clamping blocks 23 move smoothly in the radial direction, avoiding the skewing caused by the uneven elasticity of the spring plate 24, keeping the channel of the mounting cavity 2 regular, and facilitating the smooth insertion of the new valve core 3.

[0035] Please see Figure 1-5 Multiple clamping mechanisms are fixedly installed on the side wall of the mounting cavity 2. The multiple clamping mechanisms apply radial clamping force synchronously from multiple directions on the side wall of the valve core 3, so that the valve core 3 is subjected to uniform force, thereby avoiding skewing caused by force on one side. This significantly improves the stability of valve core 3 installation. In addition, two sets of telescopic structures are fixedly installed on the side wall of each clamping mechanism, thereby avoiding the reduction of the stability of clamping block 23 caused by fixation on one side.

[0036] Please see Figure 1-5 The inner diameter of the collar 12 is larger than the inner diameter of the pressure block 11, and the pressure block 11 has an L-shaped cross-section. The pressure block 11 and the collar 12 work together. When the collar 12 is installed on the valve core 3, the edge of the pressure block 11 is located in the installation seam between the collar 12 and the valve core 3, which is used to fix the valve core 3 and the collar 12. Through the cooperation of the collar 12 and the pressure block 11, the pressure block 11 transmits axial pressure to the collar 12 and the valve core 3 after the installation cover 1 is installed, thereby fixing the valve core 3 axially.

[0037] Please see Figure 1-5 The inner side of the positioning block 121 is fixedly connected to a protrusion 122 corresponding to the outer surface of the valve core 3, and the length of the positioning block 121 is consistent with the length of the notch of the clamping block 23. This is used to accurately align the valve core 3 and the inlet and outlet of the bottom of the mounting cavity 2. Through the dual positioning of the notch of the positioning block 121 and the clamping block 23, and the groove of the outer surface of the valve core 3, the angle of the valve core 3 is accurately aligned, ensuring that the inlet and outlet of the bottom of the valve core 3 is completely matched with the inlet and outlet of the bottom of the mounting cavity 2.

[0038] Please see Figure 1-5 The top of the clamping block 23 is designed with a slope to guide the valve core 3 into the installation cavity 2 along the side wall of the clamping block 23. The slope design reduces the resistance to insertion and achieves precise guidance, allowing the user to slide naturally into the installation cavity 2 without alignment, further improving the convenience of installation operation.

[0039] The working principle of this utility model is as follows: When the user replaces the valve core 3, he first removes the handle, and removes it from the upper part of the mounting cavity 2 by rotating the mounting cover 1. Then, he holds the top of the valve core 3 and pulls the valve core 3 upward. During the process of removing the valve core 3, the collar 12 is removed at the same time, and the clamping block 23 loses the squeezing force of the valve core 3. The spring plate 24 releases the stored elastic potential energy and pushes the clamping block 23 to return to the axis. At the same time, the clamping block 23 drives the telescopic plate 22 to extend towards the axis to achieve the effect of stabilizing and fixing the clamping block 23. At this time, the channel in the mounting cavity 2 reopens, which makes it easy for the new valve core 3 to be installed smoothly.

[0040] When installing the new valve core 3, slip the collar 12 onto the new valve core 3 from above and adjust the angle so that the protrusion 122 on the side of the positioning block 121 is aligned with the groove on the outer surface of the valve core 3. After that, adjust the angle of the valve core 3 until the positioning block 121 is aligned with the notch of the clamping block 23 for installation. This ensures that the inlet and outlet of the bottom of the valve core 3 are completely aligned with the inlet and outlet of the bottom of the installation cavity 2. Then, gradually insert the bottom edge of the valve core 3 into the installation cavity 2 along the inclined guide surface at the top of the clamping block 23. The side wall of the valve core 3 will squeeze the inner side of the clamping block 23, forcing the clamping block 23 to move towards the side wall of the installation cavity 2. At the same time, the telescopic plate 22 moves towards the side wall of the installation cavity 2 and retracts into the fixing block 21. At this time, the spring plate 24 is deformed by the thrust of the clamping block 23, converting mechanical energy into elastic potential energy for storage. The deformation of the spring plate 24 increases the rebound force, which is transmitted to the side wall of the valve core 3 through the clamping block 23, forming a uniform radial clamping force and achieving stable fixation.

[0041] After the valve core 3 is completely fixed by the clamping block 23, the mounting cover 1 is connected to the mounting cavity 2 and threaded. After completion, the bottom of the pressure block 11 of the mounting cover 1 is inserted into the mounting seam between the collar 12 and the valve core 3, and the pressure block 11 as a whole fixes the collar 12 and the valve core 3 to prevent the valve core 3 from axial displacement. Finally, the handle is installed.
