[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0033] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0034] Example 1:

[0035] Please see the appendix Figure 1-2 The wireless filter switcher of this application includes a main frame mechanism 1; the main frame mechanism 1 includes a lens mount 11 and a fixing base 12 connected to each other; wherein, the fixing base 12 has a first end 121, and the lens mount 11 has a second end 111, the first end 121 and the second end 111 are engaged and connected; the first end 121 has a protective edge portion 122, which surrounds the outer edge of the second end 111. The protective edge portion 122 is used to prevent light leakage.

[0036] The specific way in which the first end 121 and the second end 111 are engaged and connected is as follows: the protective edge portion 122 is provided with a first locking hole 123, and the second end 111 is provided with a first locking block 112 adapted to the first locking hole 123, and the first locking block 112 is engaged and connected with the first locking hole 123.

[0037] In this embodiment, the wireless filter switcher, through the design of the protective edge portion 122, allows the first end 121 of the fixing base 12 to surround the second end 111 of the lens mount 11, achieving a tight fit between the first end 121 and the second end 111. Furthermore, by engaging the first end 121 and the second end 111, the first end 121 of the fixing base 12 and the second end 111 of the lens mount 11 are connected. This avoids the phenomenon of the gap between the first end 121 and the second end 111 increasing due to factors such as vibration and temperature changes, effectively ensuring a long-term stable sealing effect, preventing light leakage, thereby improving the imaging quality and performance stability of the device, and enhancing its effectiveness in practical applications.

[0038] In some embodiments, please refer to the appendix. Figure 3 The mounting base 12 has second locking blocks 124 on both sides near the protective edge 122, and the lens mount 11 has second locking holes 113 that are adapted to the second locking blocks 124. The second locking blocks 124 and the second locking holes 113 are engaged. Through this setting, the mounting base 12 is embedded into the lens mount 11, that is, the second locking blocks 124 are engaged into the second locking holes 113, so as to achieve the connection stability of the mounting base 12 and the lens mount 11. Moreover, the assembly operation of the two is simple and quick, which not only improves the assembly efficiency, but also ensures the stability of the connection between the two. In this structure, the mounting base 12 and the lens mount 11 are connected by an engagement, which makes the overall structure smaller and more harmonious in appearance.

[0039] Please see Figure 4 The fixing base 12 has a third end 125 opposite to the first end 121, and guide structures 126 are provided on both sides of the third end 125 along the direction of the second end 111 from the first end 121. Preferably, the guide structure 126 has a first guide surface 1261, a second guide surface 1262, and a third guide surface 1263 that are continuous. This arrangement gives the fixing base 12 a unique three-sided guiding structure design, which can effectively reduce jamming and defects during automatic assembly, improve the convenience and ease of automatic assembly, and thus improve assembly efficiency.

[0040] Please see Figure 5 The lens mount 11 includes a mount body 114 and a copper nut 115, with the copper nut 115 located on both sides of the mount body 114. The mount body 114 has a mounting surface 116, and the copper nut 115 is positioned below the mounting surface 116. This design ensures that when the copper nut 115 is positioned below the mounting surface 116, it will not interfere with the assembly of other planar components. Furthermore, in the machining process of a sensor frame plane for a high-precision measuring instrument, if the copper nut 115 is higher than the mounting surface 116, the grinding head may encounter the copper nut 115 when grinding the mounting surface 116 using a surface grinder or similar equipment, thus compromising the flatness of the entire mounting surface 116. By positioning the copper nut 115 below the mounting surface 116, the grinding head can smoothly grind the entire mounting surface 116, thus better ensuring the flatness of the sensor frame and improving the overall performance of the assembly structure.

[0041] Specifically, the base 114 is provided with a patch groove 1141 for placing a dustproof sheet, which improves the compactness and stability of the structure assembly.

[0042] Example 2:

[0043] The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 6 This embodiment also includes a filter switching mechanism 2. The lens mount 11 and the fixing base 12 form a cavity, and the filter switching mechanism 2 is disposed in the cavity. The filter switching mechanism 2 includes a filter assembly 21, a magnetic crank assembly 22 and a U-shaped iron wire coil assembly 23. The magnetic crank assembly 22 is connected between the filter assembly 21 and the U-shaped iron wire coil assembly 23.

[0044] The wireless filter switcher in this embodiment has no exposed leads in its overall structure, reducing the need for clients to insert leads. This makes it easier for clients to automatically screw in lenses and automatically adjust focus, reducing labor and material costs and increasing efficiency. In this structure, the power-on method for finished product testing is changed, enabling fully automated production and reducing the chance of misjudgments during manual inspection.

[0045] In some embodiments, see Figure 7 The U-shaped iron coil assembly 23 includes a wire frame 231, an enameled wire 232, a U-shaped iron 233, and pins 234. The enameled wire 232 is connected to the wire frame 231, and the pins 234 are respectively connected to both ends of the wire frame 231. The U-shaped iron 233 passes through the enameled wire 232 for connection. The wire frame 231 has recesses 2311 on both sides of the enameled wire 232. Due to the small assembly gap between the wire frame 231 and the fixing base 12, the recesses 2311 effectively protect the enameled wire 232 from being snagged during assembly, ensuring assembly quality.

[0046] In some embodiments, the end of the PIN pin 234 furthest from the wire frame 231 is connected to the copper nut 115, and the end of the PIN pin 234 furthest from the wire frame 231 is arc-shaped. This design prevents the PIN pin 234 from getting stuck and damaged during assembly, effectively ensuring the assembly quality of the PIN pin 234. Furthermore, the arc-shaped PIN pin 234 allows for greater contact with the copper nut 115, facilitating subsequent soldering operations.

[0047] In some embodiments, see Figure 8 The U-shaped coil 233 is provided with a positioning hole 2331, and the fixing seat 12 is provided with a positioning post 127 corresponding to the positioning hole 2331. With this setting, during the assembly of the U-shaped coil assembly 23 and the fixing seat 12, the positioning post 127 can be inserted into the positioning hole 2331, thereby stably fixing the U-shaped coil assembly 23 and ensuring the stability of the assembly.

[0048] In some embodiments, the bracket is provided with a dispensing fixing block 2312 near the pin, and the dispensing fixing block 2312 is chamfered. With this setting, the glue can flow quickly into the fixing position after being applied during the assembly process, thereby improving the glue application efficiency.
