Description

Technical Field

[0001] This utility model relates to the field of filter switcher technology, specifically a miniature filter switcher. Background Technology

[0002] Miniature filter switchers are precision optical devices used to switch between different filters. They have important applications in fields such as spectral analysis, fluorescence microscopy, and machine vision, as well as in miniature cameras. They control the switching of filters through mechanical or electronic means. However, during use, it is inconvenient to control the rapid adjustment of filters, which affects the ease of use and stability.

[0003] To overcome the aforementioned shortcomings, existing technologies (Chinese patent application CN202120518337.7, filed on 2021-03-11) for miniature dual-filter switchers and imaging devices limit the filter mounting components by opening limiting holes, increasing the force required to drive the filter mounting components to move, thereby improving the locking force on the filter mounting components. This prevents the filters from easily moving and dislodging from their corresponding positions with the camera mounting holes when the miniature dual-filter switcher is impacted, improving the stability of the filters after switching and effectively ensuring the normal use of the imaging device. Although existing technologies can adjust the filters, during operation, it is inconvenient to control the stable assembly between the filter mounting base and the lens fixing housing, affecting the safety of assembly and use, and making it inconvenient to quickly replace the filters.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing micro filter switchers. Utility Model Content

[0005] The purpose of this invention is to provide a miniature filter switcher to solve the problems mentioned in the background art, such as the inconvenience of controlling the stable assembly between the filter mounting base and the lens fixing housing during operation, which affects the safety of assembly and use, and the inconvenience of quickly replacing the filter.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a miniature filter switcher, comprising a lens mount for stabilization, wherein a mounting base is nested on the inner surface of the lens mount; comprising: a positioning block, mounted on the outer surface of the mounting base, the outer surface of the positioning block being nested inside the lens mount, and an electromagnetic controller and a filter body being assembled on the inner surface of the mounting base; a limiting component is mounted on the upper side of the outer surface of the lens mount, and the limiting component is provided with a limiting engagement mechanism; and a hanging ear, mounted on the side of the outer surface of the lens mount, and the hanging ear is provided with a limiting compression mechanism.

[0007] Preferably, the mounting base forms a built-in limiting structure with the lens mount through the positioning block, and the mounting base forms an embedded structure with the electromagnetic controller and the filter body, and the limiting components are symmetrically embedded and installed on the upper surface of the lens mount.

[0008] Preferably, the limiting engagement mechanism includes a slider that is slidably connected to the inner surface of the limiting component, and a locking block is installed on the outer surface of the slider, which limits and engages with the locking block in the mounting base. A compression spring is elastically connected between the slider and the limiting component, and a compression block is installed on the upper surface of the slider.

[0009] Preferably, the limiting component forms an elastic sliding structure with the slider through the compression spring, and the slider forms a limiting engagement structure with the mounting base through the locking block, and the slider and the compression block form an integrated structure.

[0010] Preferably, the outer surface of the extrusion block is fitted with an extrusion member, which is slidably limited inside the limiting assembly. The outer surface of the extrusion member is equipped with a telescopic rod and a push block. A return spring is elastically connected between the push block and the limiting assembly. A handle is installed on the outer surface of the telescopic rod.

[0011] Preferably, the extrusion block and the extrusion member form an oblique extrusion structure, and the extrusion member, the telescopic rod, the push block, and the handle form an integrated structure, and the telescopic rod forms an elastic sliding structure with the limiting assembly through the push block and the return spring.

[0012] Preferably, the limiting and pressing mechanism includes a positioning ring nested on the inner surface of the ear, and a nesting member and a limiting post are installed on the lower surface of the positioning ring, which limit and engage the nesting member and the limiting post in the inner wall of the ear. An elastic pressing piece is nested and elastically connected to the inner surface of the limiting post. The ear and the outer surface of the lens mount are symmetrically embedded and installed, and the ear and the positioning ring form a nested structure. The positioning ring, the nesting member, and the limiting post form an integrated structure. At the same time, the limiting post forms a limiting internal structure with the ear through the nesting member. The outer surface of the nesting member has a serrated structure. At the same time, the limiting post forms an elastic pressing structure with the screw through the elastic pressing piece.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This miniature filter switcher is equipped with a lens mount, which facilitates the internal sliding assembly of the electromagnetic controller and filter body nested within the mount. In conjunction with the limiting components for the lens mount installation, it improves the stability of the mount during assembly, reduces the risk of vibration and detachment, and allows for quick replacement of the mount through the use of a handle. The lens mount is also equipped with a hanging lug with an elastic compression piece, which improves the stability of the lens mount installation and prevents the connecting screws from slipping.

[0015] 2. This miniature filter switcher features a limiting engagement mechanism. Symmetrically mounted limiting components on the lens mount, along with a slider adjusted by a compression spring, effectively compress and control the locking blocks mounted on the slider to engage with the mounting base. The symmetrical arrangement of the locking blocks prevents disengagement due to slight vibrations of the mounting base. Furthermore, the cooperation between the compression block and the compression component mounted on the slider facilitates filter replacement. When the filter body within the mounting base needs replacement, the compression of the compression component and the compression block adjusts the locking blocks on the slider to disengage from the limiting position, improving the ease of mounting and disassembly and increasing replacement efficiency. Moreover, the compression component, in conjunction with a push block assembled from a telescopic rod and a return spring between the push block and the limiting components, prevents interference with the normal engagement of the locking blocks and avoids automatic disengagement.

[0016] 3. This miniature filter switcher is equipped with a limiting compression mechanism. The positioning ring and limiting post nested in the lens mount are used to improve the service life of the lens mount. In addition, the elastic compression piece in the limiting post is used to compress and limit the screw during screw assembly, reducing the possibility of the screw falling off due to vibration. The nesting part installed in the limiting post also improves the stability of the embedded part between the limiting post and the lens mount. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: a miniature filter switcher, wherein a lens mount 1 is provided for stabilization, and a mounting base 2 is nested and connected to the inner surface of the lens mount 1.

[0026] Example 1: As Figures 1-3 The present invention provides the following technical solution: a miniature filter switcher, comprising: a positioning block 3, installed on the outer surface of a mounting base 2, the outer surface of the positioning block 3 being nested inside a lens mount 1, and an electromagnetic controller 4 and a filter body 5 assembled on the inner surface of the mounting base 2; a limiting component 6 is installed on the upper side of the outer surface of the lens mount 1, and the limiting component 6 is provided with a limiting engagement mechanism; the mounting base 2 and the lens mount 1 form a built-in limiting structure through the positioning block 3, and the mounting base 2, the electromagnetic controller 4, and the filter body 5 form an embedded structure, and the limiting component 6 is symmetrically embedded on the upper surface of the lens mount 1.

[0027] In use, the electromagnetic controller 4 and the filter body 5 can be stably assembled in the mounting base 2, and the positioning block 3 installed in the mounting base 2 can be used to control the mounting base 2 to carry the electromagnetic controller 4 and the filter body 5 to be stably nested in the lens mount 1. The positioning block 3 is used to perform initial positioning, and the limiting component 6 installed in the lens mount 1 is used to limit and engage the initially positioned mounting base 2 to prevent the mounting base 2 from falling off during use, and to be used for quick replacement of the filter body 5 later.

[0028] Example 2: Figure 1 , Figure 4 and Figure 5The technical solution shown, based on Embodiment 1, further discloses the nested assembly of the limiting component 6 with the mounting base 2. The specific details are as follows: The limiting engagement mechanism includes a slider 7 slidably connected to the inner surface of the limiting component 6, and a locking block 8 is mounted on the outer surface of the slider 7, which limits and engages with the mounting base 2. A compression spring 9 is elastically connected between the slider 7 and the limiting component 6, and a compression block 10 is mounted on the upper surface of the slider 7. The limiting component 6 and the slider 7 form an elastic sliding structure through the compression spring 9, and the slider 7 and the mounting base 2 form a limiting engagement structure through the locking block 8. The slider 7 and the compression block 10... The structure is integrated; the outer surface of the extrusion block 10 is attached to the extrusion member 11, and the extrusion member 11 is limited and slidably inside the limiting component 6. The outer surface of the extrusion member 11 is equipped with a telescopic rod 12 and a push block 13. At the same time, a return spring 14 is elastically connected between the push block 13 and the limiting component 6. The outer surface of the telescopic rod 12 is equipped with a handle 15. The extrusion block 10 and the extrusion member 11 form an oblique extrusion structure. The extrusion member 11, the telescopic rod 12, the push block 13 and the handle 15 form an integrated structure. The telescopic rod 12 forms an elastic sliding structure with the limiting component 6 through the push block 13 and the return spring 14.

[0029] When the mounting base 2 is nested in the lens mount 1, the compression block 8 moves centrally within the symmetrically arranged limiting components 6. The slider 7 mounted on the block 8, in conjunction with the compression spring 9 between the block 8 and the limiting components 6, retracts. When the mounting base 2 is fully assembled into the lens mount 1, the block 8 pops out elastically following the compression spring 9, stably engaging in the groove of the mounting base 2. This provides limiting and positioning for the mounting base 2, preventing slippage. Later, when the filter body 5 needs to be replaced, the telescopic rod 12 mounted on the control handle 15 slides within the limiting components 6, and in conjunction with the telescopic rod... The push block 13 installed on the control limit component 6 and the return spring 14 between the push block 13 retracts, and the extrusion member 11 installed at the end of the telescopic rod 12 will extrude the extrusion block 10 at an angle, and control the slider 7 installed on the lower side of the extrusion block 10 to slide, so that the locking block 8 will disengage from the limit of the mounting base 2, so that the mounting base 2 can be disengaged for replacement of the filter body 5. After the filter body 5 is removed, the handle 15 is released to reset the extrusion member 11 and the locking block 8 is reset to the ready-to-lock state, so as to prepare for the mounting base 2 to be assembled and improve the stability of the mounting base 2 assembly and replacement.

[0030] Example 3: Figure 1 , Figure 3 and Figure 6The technical solution shown, based on Embodiment 2, further discloses a limiting compression mechanism between the lug 16 and the screw. The specific details are as follows: The lug 16 is installed on the outer surface of the lens mount 1, and the lug 16 is provided with a limiting compression mechanism. The limiting compression mechanism includes a positioning ring 17 nested on the inner surface of the lug 16, and a nesting member 18 and a limiting post 19 are installed on the lower surface of the positioning ring 17, limiting and engaging the nesting member 18 and the limiting post 19 within the inner wall of the lug 16. An elastic compression piece 20 is nested and elastically connected to the inner surface of the limiting post 19. The lug 16 and the outer surface of the lens mount 1 are symmetrically embedded, and the lug 16 and the positioning ring 17 form a nested structure. The positioning ring 17, the nesting member 18, and the limiting post 19 form an integrated structure. Simultaneously, the limiting post 19, through the nesting member 18, forms a limiting internal structure with the lug 16. The outer surface of the nesting member 18 has a serrated structure, and the limiting post 19, through the elastic compression piece 20, forms an elastic compression structure with the screw.

[0031] After the lens mount 1 and mounting base 2 are installed, the lens mount 1 with the mounting ear 16 is assembled in the corresponding working position by passing screws through the holes opened in the mounting ear 16. When the mounting ear 16 is in use, the limiting post 19 installed in conjunction with the nested positioning ring 17 improves the positioning stability of the mounting ear 16 and reduces compression damage. The limiting post 19, which is assembled in conjunction with the nested part 18 installed on the lower side of the positioning ring 17, and the elastic compression piece 20 built into the limiting post 19, increases the compression limit with the screw, and prevents the lens mount 1 from having a gap between the working part and the working part when the screw falls off slightly, thus preventing shaking and improving the stability of the lens mount 1 in use.

[0032] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
