Description

Technical Field

[0001] This utility model relates to the field of filter holder technology, and in particular to a multi-group splicing filter holder structure that can be installed quickly. Background Technology

[0002] The filter holder is the main structure for holding filters. Currently, there aren't many structures designed as standalone filter holders; they are often a substructure within a larger system, such as the filter holder in a filter switcher. However, they cannot be used as pure filter holders in front of optical instrument lenses. In many current optical instruments, filters are often glued to the lens or fixed to it with screws. This not only hinders the placement, removal, and replacement of filters but also damages both the filters and the optical instrument, making filter use extremely inconvenient.

[0003] The patent titled "A Filter Holder for Optical Instrument Lenses" (patent application number: 201520578056.5) discloses a filter holder for optical instrument lenses. A sleeve is fitted onto the lens body, and a filter mounting platform is mounted on the sleeve. The mounting platform has a light-transmitting hole that communicates with the lens element and is located in the optical path of the lens body. Three slotted baffles are installed on the mounting platform to the left, below, and right of the light-transmitting hole. The filter is inserted into one of the three slotted baffles. This provides independent support for the installation of the filter on the optical instrument lens and allows for installation and removal as needed without damaging the optical instrument.

[0004] In the above case, when the filter needs to be fixed, the screws in the three internal threaded holes B need to be rotated to secure it. Similarly, when the filter needs to be removed, the screws in the three internal threaded holes B also need to be rotated to prevent them from contacting the filter, allowing the filter to be pulled out from the filter mounting platform. Special tools are required to rotate the screws, and operating on three screws simultaneously is time-consuming and laborious, causing inconvenience in using the filter. Therefore, it is necessary to propose a multi-unit splicing filter support structure for quick installation to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-installation multi-group splicing filter support structure to solve the problem mentioned in the background art that when the filter needs to be disassembled, it is necessary to rotate the screws in the three internal threaded holes B so that the screws do not contact the filter in order to pull the filter out of the filter mounting platform. The screws require special tools to rotate, and operating three screws at the same time is time-consuming and laborious, thus causing inconvenience to the use of the filter.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-installation multi-group splicing filter bracket structure, including a sleeve and a lens body, wherein a mounting frame is fixedly connected to the bottom of the sleeve, and a limit component is provided inside the mounting frame;

[0007] The limiting component includes a spring, a limiting plate, and a rubber pad;

[0008] The bottom end of the spring is fixedly connected to the bottom of the inner cavity of the mounting frame, the top end of the spring is fixedly connected to the bottom of the limiting plate, the top end of the limiting plate is fixedly connected to the bottom of the rubber pad, and a filter body is provided inside the mounting frame.

[0009] Preferably, both the mounting frame and the limiting plate have light-transmitting grooves inside.

[0010] Preferably, the bottom of the sleeve is provided with a light-transmitting hole, the position of which corresponds to the position of the light-transmitting groove, and the light-transmitting hole has the same light path shape as the lens body.

[0011] Preferably, the number of springs is four, and the outer side of the limiting plate is slidably connected to the inner wall of the mounting frame.

[0012] Preferably, a fixing component is provided inside the sleeve;

[0013] The fixing assembly includes a screw, a slider, and a fixing plate. The outside of the screw is threaded to the inner wall of the sleeve, and one end of the screw is rotatably connected to the slider. The side of the slider is fixedly connected to the fixing plate.

[0014] Preferably, the fixing plate is arc-shaped, and a protective pad is provided inside the fixing plate.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. By setting a limiting component, when it is necessary to place and fix the filter body, first pull the limiting plate. The limiting plate will drive the spring to move, causing the spring to undergo elastic deformation under force. Then, place the filter body inside the mounting frame. Next, release the limiting plate. The spring, which is in a compressed state, will drive the limiting plate to move, thereby squeezing and fixing the filter body. This process is simple to operate and can quickly fix or disassemble the filter body, bringing convenience to the use of the filter body.

[0017] 2. By setting up a fixing component, when it is necessary to fix the sleeve to the lens body, first, the sleeve is placed on the outside of the lens body. Then, the two screws are rotated. The two screws will drive the fixing plate to move relative to each other through the slider, thereby fixing and clamping the lens body. This makes it easier to fix the sleeve to the lens body and avoids the screw fixing method. Since the screw needs to contact the outside of the lens body, the small size of the screw can easily cause excessive local pressure on the lens body, which can damage the outside of the lens body. This improves the protection of the lens body. Attached Figure Description

[0022] 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.

[0023] This utility model provides, for example Figures 1-3The diagram shows a quick-installation multi-group splicing filter holder structure, including a sleeve 1 and a lens body 2. A mounting frame 3 is fixedly connected to the bottom of the sleeve 1. A limiting component is provided inside the mounting frame 3, which includes a spring 4, a limiting plate 5, and a rubber pad 6. The bottom end of the spring 4 is fixedly connected to the bottom of the inner cavity of the mounting frame 3, the top end of the spring 4 is fixedly connected to the bottom of the limiting plate 5, and the top end of the limiting plate 5 is fixedly connected to the bottom of the rubber pad 6. A filter body 7 is provided inside the mounting frame 3. There are four springs 4. The outside of the limiting plate 5 is slidably connected to the inner wall of the mounting frame 3. When it is necessary to place and fix the filter body 7, first pull the limiting plate 5. The limiting plate 5 will drive the spring 4 to move, causing the spring 4 to undergo elastic deformation under force. Then, place the filter body 7 inside the mounting frame 3. Next, release the limiting plate 5. The spring 4, which is in a compressed state, will drive the limiting plate 5 to move, thereby squeezing and fixing the filter body 7. This process is simple to operate and can quickly fix or disassemble the filter body 7, bringing convenience to the use of the filter body 7.

[0024] In addition, both the mounting frame 3 and the limiting plate 5 have light-transmitting grooves 8 inside, and the bottom of the sleeve 1 has a light-transmitting hole 9. The light-transmitting hole 9 corresponds to the position of the light-transmitting groove 8, and the light-transmitting hole 9 has the same optical path shape as the lens body 2. The light-transmitting groove 8 and the light-transmitting hole 9 can be used to facilitate the passage of light of a specified wavelength absorbed by the gas through the filter body 7, and the gas concentration can be determined by the amount of light attenuation.

[0025] Finally, a fixing assembly is provided inside the sleeve 1. The fixing assembly includes a screw 10, a slider 11, and a fixing plate 12. The outside of the screw 10 is threaded to the inner wall of the sleeve 1, and one end of the screw 10 is rotatably connected to the slider 11. The side of the slider 11 is fixedly connected to the fixing plate 12. The fixing plate 12 is arc-shaped and has a protective pad inside. When it is necessary to fix the sleeve 1 to the lens body 2, the sleeve 1 is first placed on the outside of the lens body 2. Then, the two screws 10 are rotated. The two screws 10 will drive the two fixing plates 12 to move relative to each other through the slider 11, thereby fixing and clamping the lens body 2. This facilitates the fixing of the sleeve 1 to the lens body 2 and avoids the screw fixing method. Since the screw needs to contact the outside of the lens body 2, the small size of the screw can easily cause excessive local pressure on the lens body 2, causing damage to the outside of the lens body 2. This improves the protection of the lens body 2.

[0026] Working principle: When the optical instrument needs to monitor the concentration of a certain gas, firstly, the sleeve 1 is placed on the outside of the lens body 2. Then, the two screws 10 are rotated, and the two screws 10 will drive the two fixing plates 12 to move relative to each other through the slider 11, thereby fixing and clamping the lens body 2, making it easy to fix the sleeve 1 to the lens body 2. Next, the limiting plate 5 is pulled, and the limiting plate 5 will drive the spring 4 to move, causing the spring 4 to undergo elastic deformation under force. Then, the filter body 7 is placed inside the mounting frame 3. Then, the limiting plate 5 is released, and the spring 4, which is in a compressed state, will drive the limiting plate 5 to move, thereby squeezing and fixing the filter body 7. The gas concentration is determined by the amount of light attenuation, which is absorbed by the gas and passes through the filter body 7.
