The contact connection method is used, and compared with the traditional dial switch, it has the advantages of simple structure, convenient connection, small size, and convenient installation and disassembly, so it can save component costs and process costs, and it is convenient to install and can save installation space.

[0033] In the embodiment of the utility model, the contact member 32 is a spring sheet, which has deformation ability and recovery ability. After being subjected to a certain degree of external force, it can be deformed and restored to its original state. In order to facilitate conduction, the spring sheet used is a metal spring sheet. Using a spring sheet as the contact member 32 can simplify the overall structure, save installation space and use space, and facilitate it to utilize its recovery ability to produce continuous and stable contact with the connection contact 23 while facilitating it to utilize its deformation ability to switch between different connection contacts 23. The contact member 32 is provided with a sliding contact (441, 442), and the sliding contact (441, 442) can contact the connection contact 23. The contact member 32 as a whole can conduct electricity. Therefore, by utilizing the sliding contact (441, 442) to slide between different connection contacts 23, different power supply circuits can be switched.

[0034] Specifically, see Figure 2The dial member 31 includes a connecting portion 311 and a paddle portion 312. The connecting portion 311 is provided with a connecting hole 313. The contact member 32 can be inserted into the connecting hole 313 to form a fixed limit. Therefore, the dial member 31 can drive the contact member 32 to move, and the contact member 32 is connected to the dial member 31 by plugging. The structure is simple and easy to install and disassemble. One end of the paddle portion 312 is connected to the connecting portion 311, and the other end protrudes toward the outside of the housing 12. When adjustment is required, the connecting portion 311 and the contact member 32 in the connecting portion 311 can be driven to move by toggling the paddle portion 312. A sliding hole 211 is provided on the light source board 21, and the length direction of the sliding hole 211 is parallel to the length direction of the adjusting hole 122, that is, the projection of the extension trajectory of the sliding hole 211 on the plane where the adjusting hole 122 is located will not intersect with the extension trajectory of the adjusting hole 122, and the sliding hole 211 and the adjusting hole 122 are both parallel to the surface of the light source board 21, and the connecting part 311 can be inserted into the sliding hole 211 and slide in the slider 211, and the connecting part 311 forms a sliding connection with the sliding hole 211, and the sliding hole 211 can limit the sliding direction of the connecting part 311.

[0035] The side wall of the shell 12 is provided with an adjustment hole 122, and the adjustment hole 122 is a long hole. The length direction of the adjustment hole 122 is parallel to the surface of the light source board 21, and the paddle portion 312 passes through the adjustment hole 122 and protrudes from the outer wall of the shell 12, so that when adjusting, the paddle portion 312 is paddled and the paddle portion 312 moves in the adjustment hole 122. Since the length direction of the adjustment hole 122 is parallel to the surface of the light source board 21, the moving directions of the paddle portion 312 and the connecting portion 311 are parallel to the surface of the light source board 21. Preferably, in an embodiment of the utility model, the connecting portion 311 moves on the surface of the light source board 21, so that the connecting portion 311 can make full use of the surface space of the light source board 21 to move without occupying additional moving space, thereby reducing the overall volume occupied by the adjustment component 3.

[0036] See also Figure 2In order to further guide the movement of the dial member 31 and avoid jamming and tripping, the dial member 31 also includes a guide rod 314, which is arranged at one end of the paddle portion 312 located inside the shell 12. The shape of the guide rod 314 corresponds to the shape of the inner wall of the shell 12, so that the side of the guide rod 314 can abut against the inner wall of the shell 12. When the dial member 31 is dialed to drive the contact member 32 to move, the guide rod 314 can slide along the inner wall of the shell 12. The interaction between the guide rod 314 and the shell 12 limits the movement trajectory of the dial member 31, so that the dial member 31 can only move along the inner wall of the shell 12. Specifically, the movement direction of the dial member 31 is horizontal, the inner side wall of the shell 12 is an arc surface, the dial member 31 can swing horizontally around the central axis of the shell 12, and the guide rod 314 ensures the swing height and direction of the dial member 31.

[0038] The adjusting hole 122 limits the movement of the paddle portion 312, and the sliding hole 211 limits the movement of the connecting portion 311 through the first limiting card plate 315 and the second limiting card plate 316, and the length direction of the sliding hole 211 is parallel to the length direction of the adjusting hole 122. While ensuring that both ends of the dial piece 31 can move smoothly in the same direction, the sliding hole 211, the first limiting card plate 315 and the second limiting card plate 316 also ensure that the contact piece 32 located in the connecting hole 313 can continue to abut against the light source panel 21.

[0039] See also Figure 4 A first buckling platform 317 is provided at the end of the first limiting card plate 315, and the first buckling platform 317 protrudes in the direction away from the connecting hole 313 and tilts from the side away from the center of the shell 12 to the side close to the center of the shell 12. A second buckling platform 318 is provided at the end of the second limiting card plate 316, and the second buckling platform 318 protrudes in the direction away from the connecting hole 313 and tilts from the side close to the center of the shell 12 to the side away from the center of the shell 12. The first buckling platform 317 and the second buckling platform 318 are provided at the end of the second limiting card plate 316. The longitudinal section of the second snap-fit ​​platform 318 is a triangle, and the inclination directions of the two are opposite. After the first limit card plate 315 and the second limit card plate 316 are inserted into the sliding hole 211, the first snap-fit ​​platform 317 and the second snap-fit ​​platform 318 can both abut against the surface of the light source panel 21. Therefore, when the first limit card plate 315 and the second limit card plate 316 slide in the sliding hole 211, the sliding hole 211 forms a horizontal limit, and the first snap-fit ​​platform 317 and the second snap-fit ​​platform 318 form a vertical limit.

[0040] The arrangement of the first snap-fit ​​platform 317 and the second snap-fit ​​platform 318 also facilitates installation and disassembly. Specifically, when connecting the dial piece 31 and the light source board 21, the first snap-fit ​​platform 317 and the second snap-fit ​​platform 318 are first brought into contact with the sliding hole 211 and inserted into the sliding hole 211. Since the first snap-fit ​​platform 317 protrudes in a direction away from the connecting hole 313 and tilts from a side away from the center of the shell 12 toward a side close to the center of the shell 12, and the second snap-fit ​​platform 318 protrudes in a direction away from the connecting hole 313 and tilts from a side close to the center of the shell 12 toward a side away from the center of the shell 12, the first snap-fit ​​platform 317 and the second snap-fit ​​platform 318 constitute an insertion structure. The width gradually narrows from the position of the first limiting card plate 315 and the second limiting card plate 316 toward the top, so it is convenient to insert into the sliding hole 211, and the sliding hole 211 has a reaction force on the first snap-fit ​​platform 317 and the second snap-fit ​​platform 318, and the distance between the first snap-fit ​​platform 317 and the second snap-fit ​​platform 318 narrows as the insertion depth of the sliding hole 211 increases, thereby further improving the convenience of inserting into the sliding hole 211. After being fully inserted into the sliding hole 211, the first snap-fit ​​platform 317 and the second snap-fit ​​platform 318 pass over the sliding hole 211 and abut against the surface of the light source board 21, forming a vertical limit, and the first limiting card plate 315 and the second limiting card plate 316 abut against both sides of the sliding hole 211, forming a horizontal limit. When disassembly is required, the first snap-fitting platform 317 and the second snap-fitting platform 318 are squeezed from the outside to make them close to each other, and the width of the insertion structure formed by the first snap-fitting platform 317 and the second snap-fitting platform 318 becomes smaller, so that the vertical limit can be loosened, so that the first snap-fitting platform 317 and the second snap-fitting platform 318 can be pulled out.

[0041] See also Figure 4The contact member 32 includes a plug-in portion 321 and a fixing portion 322, wherein the plug-in portion 321 is located at the end of the fixing portion 322. In the embodiment of the utility model, the contact member 32 is a single component, and the plug-in portion 321 and the fixing portion 322 are made by an integral molding process such as local stamping and local bending, wherein both sides of the plug-in portion 321 are provided with a limiting piece 323, one end of the limiting piece 323 is connected to the plug-in portion 321, and the other end of the limiting piece 323 is inclined toward the fixing portion 322 and extends toward the outside of the plug-in portion 321, and the plug-in portion 321 is used to insert the connection hole 313 into the The limiting piece 323 can be used to form a position with the connecting hole 313. After the plug-in part 321 is inserted into the connecting hole 313, one end of the limiting piece 323 can abut against one end of the connecting part 311 away from the first limiting card plate 315 and the second limiting card plate 316, so as to prevent the plug-in part 321 from coming out. Therefore, the limiting piece 323 and the connecting hole 313 constitute a vertical limit, and the inclined surface 319 can facilitate the compression of the limiting piece 323, so that the inclination of the limiting piece 323 is reduced, so that the plug-in part 321 is inserted into the connecting hole 313. After being inserted into the connecting hole 313, the side of the fixing part 322 is provided with a limiting boss 324, which protrudes outward and can abut against the connecting hole 313. Therefore, the limiting boss 324 and the connecting hole 313 constitute a horizontal limit.

[0042] See also Figure 5The contact member 32 further comprises a contact piece 325 and a connecting piece 326, wherein the contact piece 325 is connected to the fixed portion 322 via the connecting piece 326, wherein the connecting piece 326 is located at one end of the fixed portion 322 away from the plug-in portion 321, wherein the sliding contact (327, 328) is disposed on the contact piece 325, wherein the sliding contact (327, 328) comprises a first moving contact 327 and a second moving contact 328, wherein the contact piece 325 is made of a conductive material, and thus the first moving contact 327 and the second moving contact 328 can conduct electricity, wherein a plurality of groups of connecting contacts 23 are disposed on the light source panel 21, wherein each group of the connecting contacts 23 comprises The first fixed contact 231 and the second fixed contact 232, each group of the first fixed contact 231 and the second fixed contact 232 can form a normally open circuit with the power supply mechanism, the first fixed contact 231 and the second fixed contact 232 are equivalent to the switches of the normally open electrical circuit, and the current of the electrical circuit formed by each group of the connecting contacts 23 is different. In the process of the dial member 31 driving the contact member 32 to move, the first moving contact 327 and the second moving contact 328 can respectively contact the first fixed contact 231 and the second fixed contact 232 of each group, so that different electrical circuits form pathways, and the power supply current of the light source member 22 is changed by switching different electrical circuits to achieve a regulation effect. The number of the first fixed contacts 231 and the second fixed contacts 232 are not necessarily equal. By reasonably setting the distance between the first moving contact 327 and the second moving contact 328, when the first moving contact 327 is in contact with the first fixed contact 231, the second moving contact 328 is connected to the second fixed contact 232, and when the first moving contact 327 is in contact with the second fixed contact 232, the second moving contact 328 is connected to the first fixed contact 231.

[0043] In order to further save space, multiple groups of the first fixed contacts 231 and the second fixed contacts 232 are distributed on the same side of the sliding hole 211, the contact piece 325 extends to the same end of the connecting piece 326, and the first moving contact 327 and the second moving contact 328 are respectively arranged on opposite sides of the same end of the connecting piece 326, and multiple first fixed contacts 231 and the second fixed contacts 232 are arranged along the edge of the light source panel 21, and multiple first fixed contacts 231 are arranged between multiple second fixed contacts 232, and the first moving contact 327 and the second moving contact 328 switch between multiple first fixed contacts 231 and multiple second fixed contacts 232.

[0044] Further, see Figure 3In order to fix the light source board 21, a mounting platform 121 is provided on the inner wall of the shell 12. The mounting platform 121 is a step structure, which can support the light source board 21. The light source board 21 is fixed on the mounting platform 121. Furthermore, since the connecting portion 311 will exert a force on the light source board 21 when it moves on the surface of the light source board 21, in order to prevent the light source board 21 from rotating, a limiting block 123 is also provided on the mounting platform 121. A limiting groove 212 is provided on the light source board 21. The limiting block 123 can be inserted into the limiting groove 212, thereby limiting the light source board 21, preventing the connecting portion 311 from driving the light source board 21 to rotate during the movement, and ensuring the smooth movement of the connecting portion 311.
