Description

Technical Field

[0001] The utility model relates to the technical field of laser interferometer protection, in particular to a laser interferometer with a protection structure. Background Art

[0002] As a high-precision optical measurement tool, laser interferometer is widely used in many fields such as industrial measurement, scientific research and quality control. Its core working principle is to use laser interference phenomenon to detect small deformation or displacement of the surface of an object, so as to obtain high-precision measurement data. With the continuous advancement of science and technology, the performance of laser interferometer is also constantly improving, and the requirements for measurement accuracy, stability and ease of operation are getting higher and higher. In the design of traditional laser interferometers, more attention is often paid to the optimization of the interference system and the improvement of measurement accuracy, while the overall structural design and protective measures of the instrument are less considered. This makes the laser interferometer susceptible to interference from external environmental factors such as dust, dirt, scratches, etc. during actual use, thereby affecting its measurement accuracy and stability. In addition, since laser interferometers usually have complex structures and precise optical components, operation and maintenance are relatively difficult, requiring professional operating skills and experience. In addition, it is necessary to improve the overall structure of the laser interferometer, introduce protective measures to enhance its ability to resist environmental interference, and optimize its operation and maintenance processes to make it more suitable for actual application needs. Through improved design, laser interferometers can improve stability, reliability and ease of operation while ensuring measurement accuracy, so as to better meet the needs of various fields.

[0012] The working principle and beneficial effects of the utility model are:

[0013] 1. The utility model significantly improves the anti-falling ability of the laser interferometer by introducing a carefully constructed protective structure. Specifically, the laser interferometer body is cleverly placed in the inner wall of the protective shell. This design is not only stable but also safe. When the laser interferometer accidentally falls, the protective shell, as the first line of defense, can absorb most of the impact force, thereby reducing direct damage to the interferometer body. In addition, the threaded installation method between the bottom mounting plate and the triangular base frame is not only easy to install, but also further enhances the stability of the entire device. This dual protection mechanism makes the laser interferometer safer and more reliable during use, and effectively reduces the risk of damage caused by falling.

The existence of the protective plate effectively protects the lens in daily use and avoids damage to the lens by external factors such as dust, dirt, and scratches. In addition, the design of the protective plate also fully considers its impact on laser transmission and interferometric measurement, ensuring that while protecting the lens, it will not have any adverse effects on the performance of the laser interferometer. More importantly, when the lens needs to be cleaned, the protective plate can be easily slid up and down through a simple knob operation, making lens cleaning simple and efficient.

[0026] In this embodiment, a cavity is provided on the inner wall of the side assembly block 5 , and a slide groove is provided in the cavity of the side assembly block 5 . The slide groove of the side assembly block 5 allows the rack 9 to move up and down in the slide groove of the side assembly block 5 .

[0027] In this embodiment, the diameter of the slide groove in the cavity of the side assembly block 5 is the same as the diameter of the rack 9, and the rack 9 runs through the cavity of the side assembly block 5. When the rack 9 moves in the slide groove of the side assembly block 5, it will drive the connecting rod 10 to move synchronously.

[0028] In this embodiment, the teeth of the linkage wheel 8 mesh with the teeth of the rack 9, and the linkage wheel 8 and the rack 9 form a meshing transmission connection structure. When the linkage wheel 8 rotates, the teeth of the linkage wheel 8 will drive the teeth of the rack 9 to move, thereby causing the rack 9 to move up and down.

[0029] In this embodiment, the three-dimensional view of the protective shell 3 is a rectangular parallelepiped. The material of the protective shell 3 is carbon fiber reinforced plastic.

[0032] The working principle of this utility is:

[0033] First, when using the utility model, the laser interferometer body 1 needs to be placed in the inner wall of the protective shell 3. The user only needs to open the top plate 4 and then place the laser interferometer body 1. After the laser interferometer body 1 is placed, the user needs to align the bottom mounting plate 18 at the bottom of the protective shell 3 with the mounting position of the tripod base frame 2 and install it through threads. In daily use, the protective plate 12 can protect the lens of the laser interferometer body 1 from damage such as dust, dirt, scratches, etc. At the same time, due to the material of the protective plate 12, it will not affect the transmission and interference measurement of the laser. If the user needs to clean the lens of the laser interferometer body 1, he only needs to turn the knob 6. When the knob 6 is turned, the rotating rod 7 will be driven to rotate. When the rotating rod 7 is rotated, the linkage wheel 8 will be driven to rotate. When the linkage wheel 8 is rotated, it will drive the rack 9 to move up and down. When the rack 9 moves up and down, it will drive the connecting rod 10 to move up and down, and the connecting rod 10 will drive the linkage block 11 to slide up and down on the inner wall of the side assembly block 5, thereby making the connecting rod 10 The protective plate 12 can be driven to slide up and down. When the protective plate 12 slides to a certain height, the lens of the laser interferometer body 1 will be exposed, and then the user can clean the laser interferometer body 1. The protection of the protective shell 3 can provide a certain protection if the laser interferometer body 1 is accidentally dropped during use. At the same time, the installation method is very simple. According to different optical interference instruments on the market, optical elements may be provided on the back side of the laser interferometer body 1. If they need to be operated, the user can pull out the plug 16 on the inner wall of the fixing plate 15, and then reverse the fixing plate 15 so that the fixing plate 15 is adsorbed on the magnet 17, and then place the plug 16 on the magnet 17 for adsorption, and then flip the back plate 13 to operate the back side of the laser interferometer body 1. The utility model is easy to install, and can provide maximum protection for the laser interferometer body 1 without affecting the use of the laser interferometer body 1. At the same time, it is also very convenient to clean and remove the laser interferometer body 1. At this point, the utility model is completed.
