Description

Technical Field

[0001] This utility model relates to the field of optical testing equipment technology, and in particular to a high and low temperature optical testing equipment. Background Technology

[0002] High and low temperature optics refers to the technical field of observation, imaging, or measurement using optical principles and equipment in extreme environments such as extremely low temperatures (e.g., liquid nitrogen temperature range) or extremely high temperatures (e.g., hundreds or even thousands of degrees Celsius). It overcomes the challenge of conventional optics failing under special temperature conditions due to changes in material properties, thermal radiation interference, or environmental limitations. Through special optical materials, thermal insulation / heating designs, high-sensitivity detectors, and radiation correction techniques, it achieves precise acquisition of information such as the physical state, morphology, and thermal properties of targets at extreme temperatures. It is widely used in materials science, semiconductor processing, space exploration, and high-temperature physics research.

[0003] In high and low temperature optical testing, due to the changes in material properties at specific temperatures, it is often necessary to change lenses with different magnifications to meet diverse requirements for resolution, field of view, and accuracy. However, currently, the lens is mostly changed manually by placing it on an external worktable. This is not only cumbersome and time-consuming, but also exposes the lens to the elements for extended periods, making it susceptible to environmental influences that can cause performance fluctuations or even aging, severely impacting testing efficiency and accuracy. Utility Model Content

[0004] One objective of this invention is to provide a high and low temperature optical testing device. This invention addresses the issue mentioned in the background where, in high and low temperature optical testing, due to changes in material properties at specific temperatures, it is often necessary to change lenses with different magnifications to meet diverse requirements for resolution, field of view, and accuracy. Currently, lens replacement is mostly done manually by placing the lens on an external worktable. This is not only cumbersome and time-consuming, but also exposes the lens to the elements for extended periods, making it susceptible to environmental influences, performance fluctuations, and even aging, severely impacting testing efficiency and accuracy.

[0005] A high and low temperature optical detection device according to an embodiment of the present invention includes:

[0006] The main body of the optical inspection equipment;

[0007] The switching mechanism includes a housing installed inside the optical inspection equipment body and a protruding platform fixed at its front end. Positioning seats are fixedly installed at both the upper and lower ends of the housing. A switching disk is rotatably arranged between the upper and lower positioning seats. The outer side of the switching disk is provided with teeth and a mounting groove. A lens is installed inside the mounting groove and is fixedly connected to the switching disk via a positioning component. Fixing arms are fixedly installed on both the left and right sides of the lower positioning seat. A rotating seat is fixedly installed at the rear end of the positioning seat. A cross bracket is rotatably arranged inside the rotating seat. The cross bracket is neutralized by connecting to the fixing arms via a reset component. An L-shaped fixing plate is fixedly installed at the rear end of the upper positioning seat. A Z-shaped arc plate is fixedly installed at one bottom end of the L-shaped fixing plate. The switching disk achieves lens switching via a drive component connected to the teeth.

[0008] Preferably, the teeth and mounting slots are arranged in a circular pattern and are arranged alternately.

[0009] Preferably, the positioning component includes a cover plate that rotates around the opening end of the mounting groove, the end of the cover plate away from the mounting groove being magnetically connected by a magnetic stone, and a handle being installed on the top of the magnetic stone on the cover plate.

[0010] Preferably, the reset assembly includes a first fixing post fixed to the end of the fixing arm and a second fixing post fixed to one end of the corresponding fixing arm of the cross bracket, and a reset spring is fixedly installed between the first fixing post and the second fixing post.

[0011] Preferably, lenses with different magnifications and resolutions are placed in the mounting slots at different locations.

[0012] Preferably, the Z-shaped arc plate is fitted to the outer side of the tooth.

[0013] Preferably, the drive assembly includes a first fixed shaft, a second fixed shaft, and a T-shaped column respectively fixed to the top of the cross bracket, and an arc-shaped groove opened on the top of the housing. A left paddle and a right paddle are rotatably disposed on the upper end of the outer side of the first fixed shaft. The left paddle and the right paddle are both located on the outer side of the Z-shaped arc plate. A V-shaped spring is attached to the outer side of the left paddle and the right paddle. The T-shaped column is movably disposed inside the arc-shaped groove. A pull rope is symmetrically fixedly installed on the top of the T-shaped column, and a pull rod is fixedly disposed at one end of the pull rope.

[0014] Preferably, the end of the left paddle is attached to the inner side of the teeth in front of the Z-shaped arc plate, the end of the right paddle is attached to the inner side of the teeth behind the Z-shaped arc plate, the V-shaped spring is fixedly installed on the top of the second fixed shaft, a guide plate is fixedly installed on the top of the box corresponding to one end of the pull rope, the pull rope is movably arranged inside the guide plate, and the pull rod is located at the front end of the guide plate.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model, through its specially designed switching mechanism, effectively avoids the tedious and time-consuming manual lens changing operations, and the problem that lenses exposed to the elements for extended periods are susceptible to performance fluctuations and even aging due to environmental influences. When a lens switching operation is required, the operator simply pulls the lever in the drive assembly from outside the device. The lever, via a pull rope, moves the T-shaped column within the arc-shaped groove at the top of the housing, causing the cross bracket to rotate within the rotating seat. The rotation of the cross bracket pushes either the left or right lever on the first fixed shaft at its top. At this time, the left lever pushes the teeth in front of the Z-shaped arc plate on the switching disc, while the right lever, due to the left lever's forward movement squeezing the V-shaped spring, slides to the outside of the Z-shaped arc plate, thus disengaging from the teeth behind the Z-shaped arc plate. This drives the switching disk to rotate around the positioning seat. The rotation of the switching disk precisely rotates the lenses with different magnifications and resolutions required from the mounting slots into the optical path of the extension stage. After the switching action is completed, the pull rod is released, and the reset component immediately takes effect. The reset spring connected between the first fixed post fixed at the end of the fixed arm and the second fixed post fixed at the corresponding end of the cross bracket generates a rebound force, pulling the cross bracket to automatically return to the neutral position, preparing for the next switching operation. At the same time, the left and right levers re-engage with the teeth on the switching disk for positioning. Thus, the lens is always in the sealed box environment inside the device throughout the process, without needing to be removed or disassembled, allowing for quick switching and improving the convenience of use.

[0017] 2. This utility model, through its positioning component, allows for easy installation or replacement of specific lenses. Simply lift the cover plate by the handle on the magnetic stone at the top and rotate the cover plate away from the mounting slot opening. The lens can then be placed or removed from the corresponding mounting slot. After installation, rotate the cover plate back to its original position to cover the mounting slot opening. The magnetic stone at the far end of the cover plate will then magnetically attract the corresponding part on the switching disk, securing the lens securely inside the mounting slot. This prevents the lens from shaking or accidentally dislodging during the rotation of the switching disk, ensuring the lens's stability during testing and avoiding inaccurate test data due to lens loosening. This further guarantees the accuracy and reliability of high and low temperature optical testing. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] refer to Figures 1-5 A high and low temperature optical detection device, comprising:

[0027] Optical inspection equipment body 1;

[0028] The switching mechanism 2 includes a housing 201 installed inside the optical inspection equipment body 1, and an extension platform 202 fixed at its front end. Positioning seats 205 are fixedly installed at both the upper and lower ends inside the housing 201. A switching disk 206 is rotatably arranged between the two positioning seats 205. The outer side of the switching disk 206 is provided with teeth 207 and mounting grooves 208 respectively. A lens 209 is installed inside the mounting groove 208. The lens 209 is fixed by connecting to the switching disk 206 through a positioning component.

[0029] The positioning component includes a cover plate 210 that rotates around the opening of the mounting slot 208. The end of the cover plate 210 away from the mounting slot 208 is magnetically connected by a magnet 211. A handle 212 is installed on the top of the magnet 211 on the cover plate 210. When it is necessary to install or replace a specific lens 209, simply lift the cover plate 210 upwards and rotate it away from the opening of the mounting slot 208 by using the handle 212 on the top of the magnet 211. The lens 209 can then be placed into or removed from the corresponding mounting slot 208. After installation, the cover plate 210 is rotated back to cover the opening of the mounting slot 208. At this time, the magnet 211 at the far end of the cover plate 210 will magnetically attract the corresponding part on the switching disk 206. The lens 209 is stably encapsulated inside the mounting slot 208 by magnetic attraction, preventing it from shaking or accidentally falling out during the rotation of the switching disk 206, thereby ensuring the stability of the lens 209 during the testing process.

[0030] Fixed arms 213 are fixedly installed on both the left and right sides of the lower positioning seat 205. A rotating seat 215 is fixedly installed at the rear end of the positioning seat 205. A cross bracket 216 is rotatably installed inside the rotating seat 215. The cross bracket 216 is connected to the fixed arm 213 through a reset component to achieve neutrality.

[0031] The reset assembly includes a first fixed post 214 fixed to the end of the fixed arm 213 and a second fixed post 217 fixed to the corresponding end of the fixed arm 213 of the cross bracket 216. A reset spring 218 is fixedly installed between the first fixed post 214 and the second fixed post 217. After the switching action is completed, the lever 228 is released, and the reset assembly immediately takes effect. The reset spring 218 connected between the first fixed post 214 fixed to the end of the fixed arm 213 and the second fixed post 217 fixed to the corresponding end of the cross bracket 216 generates a rebound force, pulling the cross bracket 216 to automatically return to the neutral position, preparing for the next switching operation. At the same time, the left lever 222 and the right lever 223 re-engage and position themselves on the teeth 207 on the switching disk 206.

[0032] An L-shaped fixing plate 219 is fixedly installed at the rear end of the upper positioning seat 205. A Z-shaped arc plate 220 is fixedly installed at one bottom end of the L-shaped fixing plate 219. The switching disk 206 is connected to the tooth 207 through the drive component to realize the switching of the lens 209.

[0033] The drive assembly includes a first fixed shaft 221, a second fixed shaft 225, and a T-shaped column 226, which are respectively fixed to the top of the cross bracket 216, and an arc-shaped groove 204 opened on the top of the housing 201. The upper end of the outer side of the first fixed shaft 221 is rotatably provided with a left paddle 222 and a right paddle 223, which are both located on the outer side of the Z-shaped arc plate 220. V-shaped springs 224 are attached to the outer side of the left paddle 222 and the right paddle 223. The T-shaped column 226 is located inside the arc-shaped groove 204 and is movably arranged. A pull rope 227 is symmetrically fixedly installed on the top of the T-shaped column 226, and a pull rod 228 is fixedly installed at one end of the pull rope 227.

[0034] When it is necessary to switch lenses, the operator only needs to pull the lever 228 in the drive assembly outside the equipment. The lever 228 pulls the T-shaped column 226 to move in the arc groove 204 on the top of the housing 201 through the pull rope 227, which drives the cross bracket 216 to rotate in the rotating seat 215. The rotation of the cross bracket 216 will push the left lever 222 or the right lever 223 on the first fixed shaft 221 on its top. At this time, the left lever 222 will push the teeth in front of the Z-shaped arc plate 220 on the switching disk 206, while the right lever 223 will slide to the outside of the Z-shaped arc plate 220 after squeezing the V-shaped spring 224 when the left lever 222 is pushed forward. At this time, it will disengage from the teeth behind the Z-shaped arc plate 220, thereby driving the switching disk 206 to rotate around the positioning seat 205. The rotation of the switching disk 206 will precisely rotate the lenses 209 with different magnification and resolution from the mounting slot 208 into the optical path of the extension stage 202.

[0035] Example 1: Several circular teeth 207 and mounting slots 208 are arranged alternately, so that when the switching disk 206 rotates, it can sequentially bring the lenses 209 in the mounting slots 208 at different positions to the working position. Lenses 209 with different magnification and resolution are placed in the mounting slots 208 at different positions, which meets the diverse requirements for resolution, field of view and accuracy in high and low temperature optical detection. The Z-shaped arc plate 220 fits against the outside of the teeth 207, which increases the stability of the structure and prevents the switching disk 206 from shaking during rotation.

[0036] Example 2: The end of the left lever 222 is attached to the inner side of the teeth 207 in front of the Z-shaped arc plate, and the end of the right lever 223 is attached to the inner side of the teeth 207 behind the Z-shaped arc plate 220. The V-shaped spring 224 is fixedly installed on the top of the second fixed shaft 225. A guide plate 203 is fixedly installed on the top of the housing 201 corresponding to one end of the pull rope 227. The pull rope 227 is located inside the guide plate 203 and is movable. The pull rod 228 is located at the front end of the guide plate 203. When the pull rod 228 is pulled, the pull rope 227 drives the T-shaped column to move, thereby driving the left lever 222 and the right lever 223 to rotate. They interact with the teeth 207 to realize the rotation of the switching disk 206 and complete the lens switching.

[0037] Working principle: First, the operator pulls the lever 228 externally. The lever 228 drives the pull rope 227 to move within the guide plate 203, which in turn pulls the T-shaped column 226 to slide within the arc-shaped groove 204 at the top of the box 201. The movement of the T-shaped column 226 drives the cross bracket 216 to rotate around the rotating seat 215. The rotation of the cross bracket 216 drives the left lever 222 and the right lever 223 to move via the first fixed shaft 221. The left lever 222 conforms to the Z-shaped... The inner side of the teeth 207 in front of the arc plate 220 pushes the switching disk 206 to rotate. The right paddle 223, due to the pushing action of the left paddle 222, squeezes the V-shaped spring 224 and slides to the outside of the left paddle 222 and right paddle 223 on the outside of the Z-shaped arc plate 220. This ensures that the left paddle 222 and right paddle 223 do not disengage from the teeth 207 on the switching disk 206, and do not disengage from the rear teeth 207. The V-shaped spring 224 is fixed to the top of the second fixed shaft 225, respectively abutting against the... The lens changing plate 206 rotates around the positioning base 205, sequentially rotating the lenses 209 in the mounting slots 208 at different positions into the optical path of the extension stage 202 to achieve lens switching. After switching, the pull rod 228 is released, and the reset spring 218 in the reset assembly generates a rebound force, pulling the cross bracket 216 to automatically return to the neutral position. The left lever 222 and the right lever 223 re-engage on the teeth 207 for positioning, preparing for the next switching. When it is necessary to install or replace the lens 209, the cover plate 210 is lifted by the handle 212 to move it away from the opening of the mounting slot 208. After inserting or removing the lens 209, the cover plate 210 is rotated to reset and cover the opening. The magnet 211 at the far end of the cover plate 210 is magnetically attracted to the switching plate 206 to fix the lens 209 and prevent it from shaking or falling out. The V-shaped spring 224 is fixed to the top of the second fixed shaft 225, and the pull rope 227 is movable in the guide plate 203 to ensure the accuracy and stability of the switching process.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
