Technical Field

[0001] The present application relates to the technical field of buttons, and in particular to a button fixing assembly. Background Art

[0002] The push button switch is a common control component, usually set on the panel of the cabinet. The push button switch can cooperate with the fixed structure on the panel to realize the assembly of the push button switch. Since the push button switch is generally set in a cylindrical shape, it is necessary to pay attention to the installation angle when assembling the push button switch and prevent axial rotation after assembly.

[0003] In the prior art, a key or a key slot is provided on the push button switch, and a corresponding key slot or a key is provided on the panel. The push button switch is positioned on the panel through the engagement of the key and the key slot, and the axial rotation of the push button switch is restricted.

[0004] However, adopting this method will reduce the compatibility between the panel and the button switch. Therefore, it is urgent to propose a button fixing component to solve the problems of the prior art. Utility Model Content

[0005] The purpose of the present application is to provide a button fixing assembly that can improve the compatibility between a panel and a button switch.

[0006] The embodiment of the present application provides a button fixing assembly, which is used to fix a button to a panel, and a mounting hole is provided on the panel, and the mounting hole can be used to install the button. The button fixing assembly includes a positioning ring, the inner side of the positioning ring is directly or indirectly connected to the button, and a first positioning portion is provided on the panel. A second positioning portion and a third positioning portion are provided on the positioning ring, and one of the second positioning portion and the third positioning portion is mutually limited with the first positioning portion. When the second positioning portion is mutually limited with the first positioning portion, the size of the mounting hole is the first size, and when the third positioning portion is mutually limited with the first positioning portion, the size of the mounting hole is the second size.

[0007] The positioning ring can be used to position the connection end of the button. Specifically, the size of the inner side of the positioning ring matches the size of the connection end of the button, that is, the connection end can be restricted by the positioning ring when passing through the positioning ring, so as to improve the assembly stability of the button.

[0008] On the other hand, the positioning ring can be set to adapt the button to installation holes of different sizes. Specifically, after the positioning ring is connected to the connecting end of the button, the positioning ring is positioned and installed on the panel, and the position of the positioning ring is adjusted so that the second positioning part and the first positioning part are mutually limited, or the third positioning part and the first positioning part are mutually limited to correspond to installation holes of different sizes.

[0009] In a possible design, a first step and a second step are provided on the positioning ring, the second positioning portion is provided on the first step, and the third positioning portion is provided on the second step.

[0010] Based on the above-mentioned embodiments of the present application, the first step and the second step can separate the second positioning part from the third positioning part, so that when the positioning ring is positioned and installed with the panel, the second positioning part or the third positioning part can be accurately selected to be positioned and connected with the first positioning part, thereby improving the accuracy of positioning and installation. At the same time, assembly interference between the second positioning part or the third positioning part and the panel can be avoided, thereby improving the convenience of operation between the positioning ring and the panel.

[0011] In a possible design, the second positioning portion and the third positioning portion are configured as positioning protrusions, and the first positioning portion is configured as a positioning groove or a positioning hole. Alternatively, the second positioning portion and the third positioning portion are configured as positioning grooves or positioning holes, and the first positioning portion is configured as a positioning protrusion.

[0012] Based on the above-mentioned embodiments of the present application, the positioning ring and the panel are connected in a positioning manner by using positioning protrusions and positioning grooves, or positioning protrusions and positioning holes, which can not only realize reliable positioning between the positioning ring and the panel, but also limit the relative rotation between the positioning ring and the panel, thereby limiting the relative rotation between the button and the panel. At the same time, this setting form also has the characteristics of simple structure, easy assembly and high matching flexibility.

[0013] In a possible design, the first positioning portion is configured as a positioning groove, and the positioning groove is communicated with the mounting hole.

[0014] Based on the above-mentioned embodiment of the present application, the first positioning portion is set as a positioning groove connected to the mounting hole, which is convenient for processing and forming in production and manufacturing. At the same time, when the positioning ring is positioned and installed between the panel, it is convenient for the positioning protrusions on the first step and the second step to be clamped with the positioning groove, which is convenient for assembly.

[0015] In a possible design, the second positioning portion and the third positioning portion are arranged on a side of the positioning ring close to the panel, and the second positioning portion and the third positioning portion are located in the same direction relative to the center of the positioning ring.

[0016] Based on the above-mentioned embodiments of the present application, the second positioning part and the third positioning part are arranged on the side of the positioning ring close to the panel, so as to facilitate the connection between the second positioning part and the third positioning part and the first positioning part on the panel. At the same time, the second positioning part and the third positioning part are located in the same direction of the center of the positioning ring, so that only one first positioning part needs to be arranged on the panel, and it can be connected with the second positioning part or the third positioning part at the same time, which reduces the manufacturing cost of setting two first positioning parts and simplifies the structure of the panel.

[0017] In a possible design, a third step is further provided on the positioning ring, a fourth positioning portion is provided on the third step, and when the fourth positioning portion and the first positioning portion are mutually limited, the size of the mounting hole is a third size.

[0018] Based on the above-mentioned embodiments of the present application, the setting of the third step can further expand the application scope of the positioning ring, so that the button can be applied to more panels with mounting holes of different sizes, effectively improving the compatibility between the panel and the button, and the positioning ring has the characteristics of simple structure and easy use.

[0019] In a possible design, the button fixing assembly also includes an assembly shell for assembling the button, a first limiting portion is provided on the inner side of the positioning ring, a second limiting portion is provided on the assembly shell, the assembly shell passes through the positioning ring, and the first limiting portion and the second limiting portion limit each other.

[0020] Based on the above-mentioned embodiments of the present application, the setting of the assembly housing can protect the button and also facilitate the positioning connection between the button and the positioning ring. When the button is connected to the positioning ring, the relative rotation between the button and the positioning ring can be limited by the limiting relationship between the first limiting portion and the second limiting portion, so as to limit the relative rotation between the button and the panel after the button is assembled on the panel, thereby improving the assembly reliability and use stability of the button.

[0021] In one possible design, the first limiting portion includes at least one first limiting surface arranged on the inner wall of the positioning ring, and the second limiting portion includes at least one second limiting surface arranged on the side wall of the assembly shell, and the first limiting surface and the second limiting surface limit the relative rotation of the assembly shell and the positioning ring.

[0022] Based on the above-mentioned embodiments of the present application, the first limiting portion has at least one first limiting surface arranged on the inner wall of the positioning ring, and the second limiting portion includes at least one second limiting surface arranged on the side wall of the assembly shell. Through the arrangement of these limiting surfaces, the relative rotation between the assembly shell and the positioning ring can be effectively limited. In other words, the existence of the first limiting surface and the second limiting surface can keep the assembly shell and the positioning ring relatively still in a specific direction, ensuring the stability and reliability of the assembly structure.

[0023] In a possible design, the first limiting portion includes a limiting protrusion arranged on the inner wall of the positioning ring, and the second limiting portion includes a limiting groove arranged on the side wall of the assembly shell, and the limiting protrusion is engaged with the limiting groove to limit the rotation of the assembly shell relative to the positioning ring.

[0024] Based on the above-mentioned embodiment of the present application, the first limiting part is set as a limiting protrusion, and the second limiting part is set as a limiting groove. Through the clamping of the limiting protrusion and the limiting groove, the relative rotation between the assembly housing and the positioning ring can be more reliably limited. The technical effect is the same as the matching limiting between the first limiting surface and the second limiting surface mentioned above, which will not be repeated here.

[0025] In a possible design, the button fixing assembly further includes a fastener for fixing the button and the positioning ring to the panel, the fastener is sleeved on the button and fastened to the button. The fastener is provided with a first crimping surface and a second crimping surface, the first crimping surface crimps a side of the first step away from the panel, and the second crimping surface crimps a side of the second step away from the panel.

[0026] Based on the above-mentioned embodiments of the present application, the fastener is used to connect with the button and fix the button, the assembly shell and the positioning ring on the panel to prevent the button from loosening or shifting during operation, so as to improve the overall structural reliability and usage stability.

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

[0045] The push button switch installed on the panel is usually designed to be cylindrical, which may cause the wrong installation angle when installed on the panel, or the push button switch may rotate during use. Both of the above situations will affect the normal use of the push button switch.

[0046] In the prior art, a positioning structure capable of realizing mutual positioning is provided on the button switch and the panel, and the rotation of the button switch is limited by the positioning structure. Alternatively, a positioning member is provided between the button switch and the panel to limit the rotation of the button switch. However, the above method has the problem of poor compatibility between the panel and the button switch, which is not conducive to assembly.

[0047] Based on this, an embodiment of the present application provides a button fixing assembly, which can improve the compatibility between the panel and the button switch, simplify the assembly operation, and reduce the production process cost.

[0048] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0049] Please refer to Figure 1 and Figure 2The present embodiment provides a button fixing assembly, which is used to fix the button 3 to the panel 1. The panel 1 is provided with a mounting hole 11, and the mounting hole 11 can be used to install the button 3. The button fixing assembly includes a positioning ring 2, the inner side of which is directly or indirectly connected to the button 3, and the panel 1 is provided with a first positioning portion 12. The positioning ring 2 is provided with a second positioning portion 21 and a third positioning portion 22, and one of the second positioning portion 21 and the third positioning portion 22 is mutually limited with the first positioning portion 12. When the second positioning portion 21 is mutually limited with the first positioning portion 12, the size of the mounting hole 11 is the first size, and when the third positioning portion 22 is mutually limited with the first positioning portion 12, the size of the mounting hole 11 is the second size.

[0050] Reference Figure 2 The button 3 generally includes an operating end 31 and a connecting end 32 connected to each other. Figure 1 When the button 3 is mounted on the panel 1, the connection end 32 is inserted into the mounting hole 11 of the panel 1, the side of the operating end 31 close to the connection end 32 is close to the panel 1, and the side of the panel 1 facing the operating end 31 is the front side of the panel 1. Since the sizes of the mounting holes 11 on different panels 1 may be different, and the connection end 32 of the button 3 cannot be adapted to mounting holes 11 of different sizes, unstable installation may occur.

[0051] The positioning ring 2 can position the connection end 32 of the button 3. Specifically, the size of the inner side of the positioning ring 2 matches the size of the connection end 32 of the button 3, that is, the connection end 32 is inserted into the positioning ring 2 and can be restricted by the positioning ring 2 to improve the assembly stability of the button 3.

[0052] On the other hand, refer to Figures 3 to 6 The positioning ring 2 can be set to allow the button 3 to be installed in mounting holes 11 of different sizes. Specifically, after the positioning ring 2 is connected to the connecting end 32 of the button 3, the positioning ring 2 is positioned and installed on the panel 1. By adjusting the position of the positioning ring 2, the second positioning portion 21 and the first positioning portion 12 are mutually limited, or the third positioning portion 22 and the first positioning portion 12 are mutually limited, so as to correspond to mounting holes 11 of different sizes.

[0053] Reference Figure 3 and Figure 4 When the size of the mounting hole 11 is the first size, the second positioning portion 21 and the first positioning portion 12 are mutually limited to limit the relative rotation between the positioning ring 2 and the panel 1, and enable the button 3 to be installed on the panel 1 with the mounting hole 11 of the first size. Figure 5 and Figure 6 When the size of the mounting hole 11 is the second size, the third positioning portion 22 and the first positioning portion 12 are mutually limited so that the button 3 can be installed on the panel 1 with the mounting hole 11 of the second size.

[0054] It should be noted that the mounting hole 11 can be set to a rectangular hole or an elliptical hole, etc., as long as the mounting hole 11 can be installed with the button 3. The mounting hole 11 in the present application is set to a circular hole, and the size of the mounting hole 11 can be expressed as the diameter of the mounting hole 11. Correspondingly, the connection end 32 of the button 3 is set to a cylindrical shape, and the size of the cylindrical connection end 32 can be expressed as the diameter of the cylindrical connection end 32. In addition, the size of the inner side of the positioning ring 2 matches the size of the connection end 32, that is, the shape of the inner side of the positioning ring 2 is also circular, and the size of the inner side of the positioning ring 2 can be expressed as the diameter of the inner side of the positioning ring 2.

[0055] For example, in this embodiment, the diameter of the mounting hole 11 is or For example, the diameter of the connection end 32 of the button 3 is fixed to Correspondingly, the inner diameter of the positioning ring 2 is When the diameter of the mounting hole 11 is set to When the button 3 is installed, the connecting end 32 of the button 3 is inserted into the mounting hole 11, and the positioning ring 2 is connected to the connecting end 32 of the button 3. By adjusting the position of the positioning ring 2, the second positioning portion 21 and the first positioning portion 12 are limited to each other, so that the button 3 is positioned and installed in the mounting hole 11. At this time, the mounting hole 11 and the positioning ring 2 can simultaneously limit the connecting end 32 of the button 3, thereby improving the installation stability of the button 3.

[0056] When the diameter of the mounting hole 11 is set to When the connection end 32 of the button 3 is inserted into the mounting hole 11, the positioning ring 2 is connected to the connection end 32 of the button 3, and the position of the positioning ring 2 is adjusted so that the third positioning portion 22 and the first positioning portion 12 are mutually limited, so that the button 3 is positioned and installed in the mounting hole 11. At this time, only the positioning ring 2 has a limiting effect on the button 3. In this way, the diameter of the connection end 32 is The button 3 can be adapted to fit the mounting hole 11 with a diameter of The panel 1 improves the compatibility between the panel 1 and the button 3 and facilitates the assembly between the button 3 and the panel 1.

[0057] In an optional embodiment, the positioning ring 2 can be arranged on the front of the panel 1, that is, between the operating end 31 and the panel 1. When the button 3 is installed on the panel 1, the connecting end 32 is firstly passed through the positioning ring 2 and then passed through the mounting hole 11 to realize the positioning and installation of the button 3 on the panel 1. Figure 1 The positioning ring 2 can also be arranged on the back of the panel 1, that is, on the side of the panel 1 away from the operating end 31. When the button 3 is installed on the panel 1, the connection end 32 is firstly passed through the installation hole 11, and then passed through the positioning ring 2 to realize the positioning installation of the button 3 on the panel 1. Both of the two arrangement forms can realize the positioning installation function of the positioning ring 2 on the button 3, and have a wide range of applications.

[0058] Reference Figure 7 and Figure 8 In some embodiments, a first step 23 and a second step 24 are provided on the positioning ring 2 , the second positioning portion 21 is provided on the first step 23 , and the third positioning portion 22 is provided on the second step 24 .

[0059] Based on the above-mentioned embodiment of the present application, the first step 23 and the second step 24 can separate the second positioning portion 21 from the third positioning portion 22, so that when the positioning ring 2 is positioned and installed with the panel 1, the second positioning portion 21 or the third positioning portion 22 can be accurately selected to be positioned and connected with the first positioning portion 12, thereby improving the accuracy of positioning and installation. At the same time, assembly interference between the second positioning portion 21 or the third positioning portion 22 and the panel 1 can be avoided, so as to improve the convenience of operation between the positioning ring 2 and the panel 1.

[0060] Specifically, refer to Figure 7 and Figure 8 The second step 24 of the positioning ring 2 is the outer ring of the positioning ring 2, the first step 23 is the inner ring of the positioning ring 2 and protrudes from the second step 24 along the axial direction of the positioning ring 2, the inner ring size of the first step 23 is the same as the connecting end 32 of the button 3, when the button 3 is installed on the panel 1, the inner ring of the first step 23 is connected to the connecting end 32 to limit the installation position of the button 3.

[0061] Reference Figure 3 and Figure 4 When the size of the mounting hole 11 is set to the first size, that is, the size of the mounting hole 11, the size of the connecting end 32 of the button 3 and the inner circle size of the first step 23 are all the same, at this time, the first step 23 is close to the panel 1, the second positioning portion 21 is connected to the first positioning portion 12, and the connecting end 32 of the button 3 is restricted by the mounting hole 11 and the positioning ring 2 at the same time, which is beneficial to improve the assembly stability of the button 3.

[0062] Reference Figure 5 and Figure 6 The outer circle size of the first step 23 is the same as the second size of the mounting hole 11, that is, when the mounting hole 11 is set to the second size, the first step 23 can completely enter the mounting hole 11, and the side wall of the first step 23 away from the axis abuts against the side wall of the mounting hole 11, which can also further position the positioning ring 2, thereby improving the reliability of the button 3 and the positioning ring 2 when they are assembled on the panel 1 when the size of the mounting hole 11 does not match the size of the connecting end 32 of the button 3.

[0063] In some embodiments, the second positioning portion 21 and the third positioning portion 22 are configured as positioning protrusions, and the first positioning portion 12 is configured as a positioning groove or a positioning hole. Alternatively, the second positioning portion 21 and the third positioning portion 22 are configured as positioning grooves or positioning holes, and the first positioning portion 12 is configured as a positioning protrusion.

[0064] Based on the above-mentioned embodiments of the present application, the positioning ring 2 and the panel 1 are connected in a positioning manner by using positioning protrusions and positioning grooves, or positioning protrusions and positioning holes, which can not only realize reliable positioning between the positioning ring 2 and the panel 1, but also limit the relative rotation between the positioning ring 2 and the panel 1, thereby limiting the relative rotation between the button 3 and the panel 1. At the same time, this setting form also has the characteristics of simple structure, easy assembly and high matching flexibility.

[0065] Reference Figure 2 In this embodiment, the first positioning portion 12 is a positioning groove provided on the panel 1, the second positioning portion 21 is a positioning protrusion provided on the first step 23, and the third positioning portion 22 is a positioning protrusion provided on the second step 24. The protruding directions of the positioning protrusions are all toward the side where the panel 1 is located relative to the positioning ring 2, so that when the positioning ring 2 is close to the panel 1, the positioning protrusion can be snapped into the positioning groove.

[0066] Reference Figure 3 and Figure 4 Specifically, when the size of the mounting hole 11 is the first size, the surface portion of the first step 23 on the positioning ring 2 facing the panel 1 abuts against the panel 1. At this time, the second positioning portion 21 is connected to the first positioning portion 12, that is, the positioning protrusion on the first step 23 is snapped into the positioning groove on the panel 1.

[0067] Reference Figure 5 and Figure 6 When the size of the mounting hole 11 is the second size, the first step 23 on the positioning ring 2 extends into the mounting hole 11 as a whole, and the second step 24 abuts against the panel 1 toward the surface of the panel 1. At this time, the third positioning portion 22 is connected to the first positioning portion 12, that is, the positioning protrusion on the second step 24 is snapped into the positioning groove on the panel 1.

[0068] In summary, this arrangement effectively simplifies the positioning and assembly operation between the positioning ring 2 and the panel 1 , so that the positioning ring 2 can adjust the positioning position in time according to the mounting hole 11 of the panel 1 , so as to position and install the button 3 into the mounting hole 11 .

[0069] Similarly, if the first positioning portion 12 is set as a positioning protrusion, and the second positioning portion 21 and the third positioning portion 22 are set as positioning grooves, when the positioning ring 2 and the panel 1 are positioned and assembled, the positioning between the positioning ring 2 and the panel 1 can be achieved by adopting the same assembly method as above.

[0070] In addition, the positioning groove and the positioning hole are also used to limit the positioning protrusion. The difference between the two is that the positioning groove has a smaller impact on the overall structure of the panel 1, and the positioning hole is convenient for visually observing whether the positioning protrusion accurately enters the positioning hole, and the positioning hole has a higher reliability in positioning the positioning protrusion. Therefore, the positioning groove or the positioning hole can be selected according to specific production needs.

[0071] In further implementation, the shapes and sizes of the first positioning portion 12, the second positioning portion 21 and the third positioning portion 22 can be optimized according to production and use requirements. For example, the positioning protrusion and the positioning groove or positioning hole can have a specific geometric shape, such as a circle, a square, an ellipse or an arbitrary curve shape, to achieve a tighter fit and a more stable positioning effect.

[0072] In addition, two first positioning portions 12 can be provided on the panel 1, and the two first positioning portions 12 can be connected to the third positioning portion 22 and the fourth positioning portion respectively. Such a setting can realize the positioning of the positioning ring 2 from different directions when the positioning ring 2 is positioned and installed in the mounting holes 11 of different sizes, thereby improving the positioning reliability.

[0073] In an optional embodiment, the positioning ring 2 and the panel 1 can also be positioned by magnetic attraction or the like. For example, a magnetic attraction piece is provided on the panel 1, a first magnet is provided on the first step 23 of the positioning ring 2, and a second magnet is provided on the second step 24. When the positioning ring 2 is positioned and installed on the panel 1, by adjusting the magnet magnetically connected to the magnetic attraction piece, a reliable positioning connection between the positioning ring 2 and the panel 1 can also be achieved, thereby facilitating the assembly of the button 3 on the panel 1 with mounting holes 11 of different diameters.

[0074] In some embodiments, reference Figure 6 The first positioning portion 12 is configured as a positioning groove, and the positioning groove is connected to the mounting hole 11 .

[0075] Based on the above-mentioned embodiment of the present application, the first positioning portion 12 is set as a positioning groove connected to the mounting hole 11, which is convenient for processing and molding in production and manufacturing. At the same time, when the positioning ring 2 is positioned and installed between the panel 1, it is convenient for the positioning protrusions on the first step 23 and the second step 24 to be engaged with the positioning groove, which is convenient for assembly.

[0076] Reference Figure 4 and Figure 6 Specifically, the positioning groove is arranged on the inner side wall of the mounting hole 11, and the positioning protrusion on the first step 23 is arranged on the surface of the first step 23 facing the panel 1. When the size of the mounting hole 11 is a first size, the surface of the first step 23 on the positioning ring 2 facing the panel 1 abuts against the panel 1. At this time, the positioning protrusion on the first step 23 can be inserted into the positioning groove to limit the rotation of the positioning ring 2.

[0077] Reference Figure 6 When the size of the mounting hole 11 is the second size, the first step 23 can be fully inserted into the mounting hole 11. At this time, the second step 24 abuts against the panel 1 with its surface facing the panel 1, and the positioning protrusion on the second step 24 can be inserted into the positioning groove to limit the rotation of the positioning ring 2.

[0078] In summary, this arrangement effectively simplifies the assembly operation between the positioning ring 2 and the panel 1, and facilitates the positioning ring 2 to adjust the positioning installation with the panel 1 in time while positioning and assembling the button 3, so that the button 3 can be fixed in the mounting holes 11 of different sizes.

[0079] In some embodiments, reference Figure 7 The second positioning portion 21 and the third positioning portion 22 are arranged on a side of the positioning ring 2 close to the panel 1 , and the second positioning portion 21 and the third positioning portion 22 are located in the same direction relative to the center of the positioning ring 2 .

[0080] Based on the above-mentioned embodiments of the present application, the second positioning portion 21 and the third positioning portion 22 are arranged on the side of the positioning ring 2 close to the panel 1, so as to facilitate the connection between the second positioning portion 21 and the third positioning portion 22 and the first positioning portion 12 on the panel 1. At the same time, the second positioning portion 21 and the third positioning portion 22 are located in the same direction of the center of the positioning ring 2, so that only one first positioning portion 12 needs to be arranged on the panel 1, and it can be connected with the second positioning portion 21 or the third positioning portion 22 at the same time, which reduces the manufacturing cost of setting two first positioning portions 12 and simplifies the structure of the panel 1.

[0081] In some embodiments, a third step is further provided on the positioning ring 2 , a fourth positioning portion is provided on the third step, and when the fourth positioning portion and the first positioning portion 12 are mutually limited, the size of the mounting hole 11 is a third size.

[0082] Based on the above-mentioned embodiments of the present application, the setting of the third step can further expand the application scope of the positioning ring 2, so that the button 3 can be applied to more panels 1 with mounting holes 11 of different sizes, effectively improving the compatibility between the panel 1 and the button 3, and the positioning ring 2 has the characteristics of simple structure and easy use.

[0083] The third step is arranged on the side of the second step 24 away from the first step 23, the fourth positioning portion is arranged on the side of the third step facing the panel 1, and the fourth positioning portion, the third positioning portion 22 and the second positioning portion 21 are also located in the same direction of the center of the positioning ring 2. When the size of the mounting hole 11 is the third size, the positioning ring 2 and the panel 1 can be positioned and installed by adjusting the position of the positioning ring 2 so that the fourth positioning portion and the first positioning portion 12 are mutually limited, so that the button 3 can be positioned and installed on the panel 1 having the mounting hole 11 of the third size.

[0084] Furthermore, a fourth step may be provided on the positioning ring 2, and a fifth positioning portion may be provided on the fourth step. When the fifth positioning portion and the first positioning portion 12 are mutually limited, the size of the mounting hole 11 is a fourth size. Similar to the above-mentioned embodiment, the provision of the fourth step and the fifth positioning portion may also improve the compatibility between the panel 1 and the button 3, and has the same technical effect as the above-mentioned embodiment, which will not be described in detail.

[0085] In some embodiments, reference Fig. 9 and Fig.10 The button fixing assembly also includes an assembly shell 33 for assembling the button 3. A first limiting portion 25 is provided on the inner side of the positioning ring 2. A second limiting portion 331 is provided on the assembly shell 33. The assembly shell 33 passes through the positioning ring 2. The first limiting portion 25 and the second limiting portion 331 limit each other.

[0086] Based on the above-mentioned embodiments of the present application, the arrangement of the assembly housing 33 can protect the button 3 and also facilitate the positioning connection between the button 3 and the positioning ring 2. When the button 3 is connected to the positioning ring 2, the relative rotation between the button 3 and the positioning ring 2 can be limited by the limiting relationship between the first limiting portion 25 and the second limiting portion 331, so as to limit the relative rotation between the button 3 and the panel 1 after the button 3 is assembled to the panel 1, thereby improving the assembly reliability and use stability of the button 3.

[0087] Reference Fig. 9 and Fig.10 , wherein the assembly shell 33 is arranged on the connection end 32 of the button 3. When the button 3 is connected to the positioning ring 2, the connection end 32 of the button 3 together with the assembly shell 33 are inserted into the positioning ring 2, and the first limiting portion 25 on the inner side of the positioning ring 2 and the second limiting portion 331 on the assembly shell 33 limit each other, so that the assembly shell 33 together with the button 3 can rotate relative to the positioning ring 2, thereby preventing the button 3 from rotating during use, thereby preventing the normal use of the button 3 and the device where the button 3 is located from being affected.

[0088] The cooperation between the first limiting portion 25 on the positioning ring 2 and the second limiting portion 331 on the assembly housing 33 can be configured as a snap connection or a pin connection, etc., so long as the positioning ring 2 can limit the assembly housing 33 from rotating in the positioning ring 2. Two specific implementation forms are provided below:

[0089] In one implementation, referring to Figure 7 and Fig.10 The first limiting portion 25 includes at least one first limiting surface arranged on the inner wall of the positioning ring 2, and the second limiting portion 331 includes at least one second limiting surface arranged on the side wall of the assembly shell 33. The first limiting surface and the second limiting surface limit the relative rotation of the assembly shell 33 and the positioning ring 2.

[0090] Based on the above-mentioned embodiment of the present application, the first limiting portion 25 has at least one first limiting surface arranged on the inner wall of the positioning ring 2, and the second limiting portion 331 includes at least one second limiting surface arranged on the side wall of the assembly housing 33. Through the arrangement of these limiting surfaces, the relative rotation between the assembly housing 33 and the positioning ring 2 can be effectively limited. In other words, the existence of the first limiting surface and the second limiting surface can keep the assembly housing 33 and the positioning ring 2 relatively still in a specific direction, ensuring the stability and reliability of the assembly structure.

[0091] The first limiting surface can be a smooth, sharp surface or a surface with other specific shapes and characteristics, and the second limiting surface is set to a surface with a shape and characteristics matching the first limiting surface. For example, the first limiting surface is a V-shaped concave surface set on the inner wall of the positioning ring 2, and the second limiting surface is a V-shaped convex surface set on the side wall of the assembly shell 33. When the positioning ring 2 is connected to the assembly shell 33, the V-shaped concave surface is connected to the V-shaped convex surface to limit the relative rotation between the assembly shell 33 and the positioning ring 2.

[0092] This design aims to achieve precise matching and relative stillness between the assembly housing 33 and the positioning ring 2 through the shape matching between the positioning ring 2 and the assembly housing 33, avoiding the problem of wrong installation angle of the button 3 during the assembly process and the rotation of the button 3 during use, thereby improving the assembly efficiency and accuracy of the button 3. In addition, this design also has the advantages of easy manufacturing, low cost, and high stability.

[0093] In another implementation, referring to Figure 7 and Fig.10 The first limiting portion 25 includes a limiting protrusion arranged on the inner wall of the positioning ring 2, and the second limiting portion 331 includes a limiting groove arranged on the side wall of the assembly shell 33. The limiting protrusion is engaged with the limiting groove to limit the rotation of the assembly shell 33 relative to the positioning ring 2.

[0094] Based on the above-mentioned embodiment of the present application, the first limiting portion 25 is set as a limiting protrusion, and the second limiting portion 331 is set as a limiting groove. Through the clamping of the limiting protrusion and the limiting groove, the relative rotation between the assembly housing 33 and the positioning ring 2 can be more reliably limited. The matching limiting between the first limiting surface and the second limiting surface has the same technical effect, which will not be repeated here.

[0095] The limiting protrusion can be a protrusion, a column or other structure with a specific shape and characteristics, and the shape of the limiting groove is set to have an opening or a groove or other structure that matches the limiting protrusion. For example, in this embodiment, the limiting protrusion is a rectangular protrusion set on the inner wall of the positioning ring 2, and the limiting groove is set to a sliding groove that matches the shape. When the assembly shell 33 is assembled with the positioning ring 2, a snap fit is formed between the limiting protrusion and the limiting groove. This snap fit can effectively limit the rotation of the assembly shell 33 relative to the positioning ring 2, ensuring that the assembly shell 33 always maintains a precise position during the assembly process.

[0096] At the same time, by adjusting the shape, size and distribution of the limiting protrusions and the limiting grooves, we can achieve accurate limiting of the assembly housing 33 and improve the stability and reliability of assembly. Compared with the previous implementation, this design using limiting protrusions and limiting grooves has the advantages of simple manufacturing, low cost, compact structure, etc.

[0097] In addition, the first implementation method and the second implementation method can be used simultaneously between the positioning ring 2 and the assembly shell 33, which can further improve the positioning accuracy and reliability between the positioning ring 2 and the assembly shell 33 and reduce the possibility of deflection of the button 3 when assembled to the panel 1.

[0098] In some embodiments, referring to Figure 3 and Figure 4 The button fixing assembly further includes a fastener 4 for fixing the button 3 and the positioning ring 2 to the panel 1. The fastener 4 is sleeved on the button 3 and is fastened to the button 3. The fastener 4 is provided with a first crimping surface 41 and a second crimping surface 42. The first crimping surface 41 crimps the side of the first step 23 away from the panel 1, and the second crimping surface 42 crimps the side of the second step 24 away from the panel 1.

[0099] Based on the above-mentioned embodiments of the present application, the fastener 4 is used to connect with the button 3, and fix the button 3, the assembly shell 33 and the positioning ring 2 on the panel 1 to prevent the button 3 from loosening or shifting during operation, so as to improve the overall structural reliability and usage stability.

[0100] Specifically, refer to Fig.11 The fastener 4 is set in an annular shape, and the inner ring of the fastener 4 is provided with a fastening thread. The side wall of the assembly housing 33 is also provided with a fastening thread. After the button 3, the assembly housing 33 and the positioning ring 2 are assembled to the panel 1, the fastener 4 can be connected to the assembly housing 33 from the back of the panel 1, so as to fix the button 3 as a whole on the panel 1. Through the joint action of the fastener 4 and the positioning ring 2, the button 3 can be positioned at the installation angle on the panel 1, and the button 3 can be adapted to the mounting holes 11 of different sizes, and the button 3 can be stably assembled on the panel 1.

[0101] Furthermore, the side of the fastener 4 facing the panel 1 is set as an abutting surface. When the positioning ring 2 is installed on the back of the panel 1, the abutting surface abuts the positioning ring 2 and presses the positioning ring 2 against the back of the panel 1. When the positioning ring 2 is set on the front of the panel 1, the positioning ring 2 is located between the operating end 31 of the button 3 and the panel 1. After tightening the fastener 4, the operating end 31 of the button 3 will press the positioning ring 2 against the panel 1 to fix the positioning ring 2.

[0102] Furthermore, refer to Fig.11 The abutting surface of the fastener 4 includes a first crimping surface 41 and a second crimping surface 42. The first crimping surface 41 is located at the inner circle of the abutting surface, and the second crimping surface 42 is located at the outer circle of the abutting surface. When the fastener 4 abuts against the positioning ring 2, the first crimping surface 41 abuts against the side of the first step 23 away from the panel 1, and the second crimping surface 42 abuts against the side of the second step 24 away from the panel 1. This design can effectively increase the contact area between the fastener 4 and the positioning ring 2, so that the positioning ring 2 is evenly stressed and the positioning ring 2 is prevented from being squeezed and deformed.

[0103] Reference Figure 3 and Figure 4 When the size of the mounting hole 11 is the first size, the first step 23 on the positioning ring 2 abuts against the panel 1 toward the side of the panel 1. After the fastener 4 is tightened, the positioning ring 2 will undergo a small amount of deformation. At this time, the first crimping surface 41 is mainly used to crimp the side of the first step 23 away from the panel 1 and bear the crimping force.

[0104] Reference Figure 5 and Figure 6 When the size of the mounting hole 11 is the second size, the second step 24 on the positioning ring 2 abuts against the panel 1 on the side facing the panel 1. After the fastener 4 is tightened, the second crimping surface 42 mainly crimps the side of the second step 24 away from the panel 1 and bears the crimping force. Therefore, the fastener 4 adopts this arrangement to change the position of the pressing force on the positioning ring 2 according to the different use positions of the positioning ring 2, which is conducive to reducing the risk of destructive deformation of the positioning ring 2, improving the stability of the positioning ring 2 and extending the service life.

[0105] In addition, refer to Fig.11 In this embodiment, the first crimping surface 41 is set to be serrated. This setting can increase the friction between the first crimping surface 41 and the crimped surface, reduce the risk of the fastener 4 loosening, and improve the fastening reliability of the fastener 4.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
