Description

Technical Field

[0001] The utility model relates to the field of bathroom products, in particular to a knob structure applied to a water valve. Background Art

[0002] The patent document with Chinese patent authorization publication number CN216666607U discloses a technical solution entitled "A switch structure applied to a basin faucet, bathtub faucet or concealed valve" (which is a patent owned by the present applicant). In this technical solution, in order to replace the toggle part on the knob body with a toggle part with a different matching one, the following structure is adopted: the switch structure applied to the basin faucet, bathtub faucet or concealed valve also includes a toggle block, a plug-in protrusion is provided on the side wall of the toggle block, an plug-in hole is provided on the circumferential surface of the knob cap, a second threaded hole is provided on the inner end surface of the knob cap that penetrates into the plug-in hole, the plug-in protrusion is inserted into the plug-in hole, a second set screw is screwed into the second threaded hole, and the second set screw is tightly pressed against the plug-in protrusion.

[0003] It can be seen that the positioning of the toggle block is achieved by the second set screw pressing the plug-in protrusion. In order to facilitate processing, in the actual manufacturing process, the plug-in protrusion is a cylinder and the plug-in hole is a round hole that matches the plug-in protrusion (see the above patent document). Figure 6 10), the positioning effect of the insertion hole on the insertion protrusion is limited, especially the positioning effect on the circumferential direction of the insertion protrusion is very weak. In addition, the insertion protrusion is positioned by pressing the circumferential surface of the insertion protrusion with the second set screw. Although this can enhance the installation and positioning strength of the insertion protrusion, it still has a very weak positioning effect on the circumferential direction of the insertion protrusion. Since the toggle block is mainly subjected to the force from the side wall during use, and this force is difficult to act evenly on the axial center position or both sides of the insertion protrusion, it is easy to cause the toggle block to become skewed after a period of use. This will not only bring inconvenience to the use of the thumb, but also affect the quality of the knob body, which brings great trouble to the user.

[0004] Therefore, it is very necessary to design a knob structure applied to a water valve to solve the above technical problems. Utility Model Content

[0025] like Figures 1 to 5 As shown, the knob structure used on the water valve described in the utility model includes a knob body 1 and a toggle block 2. The side wall of the toggle block 2 is provided with an insertion column 21. In order to achieve the purpose of the invention of the utility model, a limiting groove 11 is provided on the side wall of the knob body 1, and the bottom of the limiting groove 11 is provided with an insertion hole 12. The side of the toggle block 2 is embedded in the limiting groove 11, and the insertion column 21 is inserted into the insertion hole 12.

[0026] In this knob structure, a limiting groove 11 is provided on the side wall of the knob body 1, and the side portion of the toggle block 2 is embedded in the limiting groove 11. This not only meets the normal toggle demand of the toggle block 2, but also can utilize the limiting groove 11 to limit the toggle block 2, thereby helping to improve the accuracy and stability of the installation and positioning of the toggle block 2. An insertion hole 12 is provided at the bottom of the limiting groove 11, and the insertion column 21 is inserted into the insertion hole 12. This not only facilitates manufacturing and assembly, but also helps to further enhance the stability and reliability of the installation and positioning of the toggle block 2. Such a knob structure can position the toggle block 2 more accurately, stably and reliably, and the toggle block 2 will not be skewed under long-term use. This not only ensures that long-term use is very convenient, but also has more stable and reliable quality, thereby solving a lot of troubles for users.

[0027] like Figure 3 、 Figures 5 to 7 As shown, the bottom surface of the knob body 1 is provided with a first screw hole 13 extending through the insertion hole 12. A first set screw 10 is threaded into the first screw hole 13, pressing the first set screw 10 against the insertion post 21. This not only conceals the first screw hole 13 and the first set screw 10, but also provides a more stable and reliable positioning of the insertion post 21, thereby further improving the stability and reliability of the installation and positioning of the toggle block 2.

[0028] like Figure 6 and Figure 7 As shown, the knob body 1 has a fitting hole 14 defined in the middle of its bottom surface. An annular groove 15 surrounds the fitting hole 14. A first reinforcement 151 connects its inner and outer walls at its bottom. The inner end of the insertion hole 12 extends through the first reinforcement 151, and the first screw hole 13 is formed in the first reinforcement 151. The fitting hole 14 allows for easy installation onto the valve stem of a water valve, improving installation accuracy and stability. The annular groove 15 reduces raw material usage when the knob body 1 is designed for a larger size suitable for human handling, thereby reducing manufacturing costs. The first reinforcement 151 ensures a stable and reliable reinforcement effect, effectively enhancing the structural strength of the area where the insertion hole 12 and the first screw hole 13 meet. This ensures the knob structure has reliable structural strength and durability while reducing material consumption.

[0029] like Figure 6 As shown, the set hole 14 is a spline hole. Such a set hole 14 can be easily set on the valve core rod of the water valve in a spline-fitting manner, thereby being beneficial to the stability and reliability of installation and use.

[0030] like Figure 7As shown, a recess 141 having a depth greater than the spline tooth groove depth is provided on the hole wall at the upper end of the sleeve hole 14. This facilitates the opening of the spline hole, thereby contributing to improving manufacturing convenience.

[0031] like Figure 3 、 Figure 6 and Figure 7 As shown, the bottom of the annular groove 15 is provided with a second reinforcement portion 152 connecting its inner and outer groove walls. A mounting hole 16 is defined in the sidewall of the knob body 1. A second screw hole 161 is defined at the bottom of the mounting hole 16. The second screw hole 161 extends through the second reinforcement portion 152 and communicates with the sleeve hole 14. A shielding plug 17 is embedded in the mounting hole 16. This arrangement of the second reinforcement portion 152 ensures a highly stable and reliable reinforcement effect, effectively enhancing the structural strength of the area where the second screw hole 161 is located. This, in turn, ensures the knob structure possesses highly reliable structural strength and durability while reducing material consumption. The second screw hole 161 accommodates the second set screw 20, which facilitates the use of the set screw to enhance the stability and reliability of the knob structure's installation and positioning. By opening a second screw hole 161 at the bottom of the embedding hole 16 and embedding a shielding plug 17 in the embedding hole 16, this not only meets the normal screw connection requirements of the second fastening screw 20, but also facilitates the accurate positioning of the shielding plug 17 and enables the shielding plug 17 to exert a stable and reliable shielding effect, which can ensure that the knob structure has high quality.

[0032] like Figure 6 As shown, the first reinforcement portion 151 and the second reinforcement portion 152 are arranged in a spatially vertical relationship. This not only can better play the reinforcing role, but also can facilitate the installation of related components on the knob body 1, thereby helping to further improve the reliability and applicability of the knob structure.

[0033] like Figure 6 As shown, the sidewalls of the first reinforcement portion 151 are connected to the inner and outer groove walls of the annular groove 15 in a circular arc transition, and the sidewalls of the second reinforcement portion 152 are connected to the inner and outer groove walls of the annular groove 15 in a circular arc transition. This not only facilitates manufacturing and molding, but also further improves structural strength, thereby enabling the first reinforcement portion 151 and the second reinforcement portion 152 to have a more stable and reliable reinforcement effect.

[0034] like Figures 1 to 4 、 Figure 7 As shown, the top surface of the knob body 1 is provided with a positioning groove 18, into which the decorative block 3 is embedded. The positioning groove 18 facilitates accurate and stable positioning of the decorative block 3, thereby improving the accuracy and stability of the installation of the decorative block 3. The installation of the decorative block 3 improves the quality of the knob structure, thereby providing a better user experience.

[0035] like Figures 1 to 4 As shown, the top surface of the decorative block 3 is arc-shaped, truncated cone-shaped or multi-faceted, etc., which can meet the decorative requirements.

[0036] like Figure 3 As shown, an adhesive sheet 181 is provided between the bottom surface of the decorative block 3 and the bottom of the positioning groove 18. The use of the adhesive sheet 181 not only controls the space occupied, but also adheres and fixes the decorative block 3 to the positioning groove 18, which helps to further improve the stability and reliability of the installation and positioning of the decorative block 3.

[0037] The adhesive sheet 181 can be made of adhesive glue or double-sided tape, which can meet the actual manufacturing and assembly requirements.

[0038] like Figure 6 and Figure 7 As shown, a vent hole 182 is formed at the bottom of the positioning groove 18 and extends through the bottom surface of the knob body 1. The vent hole 182 not only reduces the use of raw materials, but also serves to exhaust the air inside when installing the adhesive sheet 181 or the decorative block 3, thereby making the installation of the adhesive sheet 181 or the decorative block 3 more convenient and smooth, thereby helping to improve the convenience of assembly.

[0039] like Figure 6 and Figure 7 As shown, the vent hole 182 penetrates into the sleeve hole 14, which is not only convenient for opening but also ensures that the knob body 1 has high structural strength.

[0040] like Figure 6 As shown, anti-slip grooves 19 are provided on the outer circumferential surface of the knob body 1. This can prevent slipping when the knob body 1 is rotated, thereby being conducive to bringing a better user experience.

[0041] The anti-skid patterns 19 can be either anti-skid vertical patterns or anti-skid mesh patterns, so as to achieve an anti-skid effect.

[0042] like Figure 3 and Figure 6 As shown, the bottom surface of the knob body 1 is provided with an embedding groove 111, into which a wear-resistant ring 112 is embedded, with the lower end of the wear-resistant ring 112 protruding out of the embedding groove 111. This allows the wear-resistant ring 112 to contact the water valve housing or other components of the water valve, preventing the knob body 1 from directly contacting the water valve housing or other components. This not only facilitates accurate installation and positioning of the knob structure, but also achieves a wear-resistant effect, thereby improving reliability and durability.
