Description

Technical Field

[0001] This utility model relates to the field of optical rotators, and in particular to a precise angle adjustment seat for optical rotators. Background Technology

[0002] A polarimeter is an instrument for measuring the optical rotation of a substance. Its working principle is based on the property that certain substances can cause the vibration direction of plane-polarized light to rotate. By measuring the angle of rotation of polarized light caused by the sample (i.e., optical rotation), the concentration, content, purity, and other properties of the substance can be further analyzed. These instruments typically include key components such as a light source (e.g., a sodium lamp), a polarizer, an analyzer, and a sample tube.

[0003] However, most existing polarimeters have non-adjustable angles, and the observer of the polarimeter is fixed to the support plate, making it difficult to adapt to samples of different shapes and sizes, thus reducing the application range of the polarimeter and consequently reducing its adaptability. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a rotator angle precision adjustment seat.

[0005] This utility model is achieved using the following technical solution: a gyroscope angle precision adjustment seat, including a support plate, an adjustment component is provided on the top of the support plate, a gyroscope is provided on the inner wall of the adjustment component, the top of the support plate is fixedly connected to a connecting seat, a sodium lamp is provided on the top of the inner wall of the connecting seat, and the bottom of the support plate is fixedly connected to a support foot.

[0006] The adjustment assembly includes a fixed plate with a sliding groove on its inner wall. A limiting rack groove is formed at the end of the sliding groove away from the optical rotator. A limiting rack ring is engaged with the inner wall of the limiting rack groove. A connecting post is slidably connected to the inner wall of the limiting rack ring. A limiting groove is formed on the inner wall of the connecting post at the end away from the optical rotator. A spring is fixedly connected to the end of the connecting post near the limiting groove. A pressing shell is fixedly connected to the end of the spring away from the connecting post. A sliding post is fixedly connected to the inner wall of the pressing shell. A connecting sleeve is fixedly connected to the end of the connecting post away from the spring.

[0007] Through the above technical solution, pressing the pressing shell compresses the spring, causing the sliding column to slide along the inner wall of the limiting groove, thus disengaging the limiting rack ring from the limiting rack groove. Then, rotating the pressing shell through the limiting groove causes the connecting column to rotate the polarizer inside the connecting sleeve, thereby adjusting the polarizer's angle to the desired position. Releasing the pressing shell then extends the spring, causing the pressing shell to re-engage the limiting rack ring with the limiting rack groove, thus fixing the adjusted angle of the polarizer. This allows the adjusting seat to flexibly adjust the polarizer's angle, adapting it to samples of different shapes and sizes, expanding the polarizer's applicability, and improving the device's practicality.

[0008] As a further improvement to the above solution, two fixing plates are provided, and the two fixing plates are symmetrically distributed around the support plate.

[0009] By using the above technical solution, a spring is set so that when the pressing shell is not pressed by external force, the spring extends, causing the pressing shell to drive the limiting rack ring to re-engage with the limiting rack groove, thereby fixing the optical rotator at the adjusted angle.

[0010] As a further improvement to the above solution, the surface of the limiting rack ring is slidably connected to the inner wall of the sliding groove.

[0011] As a further improvement to the above solution, the surface of the pressing shell is slidably connected to the inner wall of the fixing plate.

[0012] As a further improvement to the above solution, the end of the pressing shell near the connecting post is fixedly connected to the surface of the limiting rack ring.

[0013] As a further improvement to the above solution, the surface of the sliding column is slidably connected to the inner wall of the limiting groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention features an adjustment mechanism. Specifically, pressing the pressing shell compresses the spring, causing the sliding column to slide along the inner wall of the limiting groove. This disengages the limiting rack ring from the limiting rack groove. Rotating the pressing shell then causes the connecting column to rotate the polarimeter inside the connecting sleeve, adjusting the polarimeter's angle to the desired position. Releasing the pressing shell extends the spring, causing the pressing shell to re-engage the limiting rack ring with the limiting rack groove, thus fixing the adjusted polarimeter angle. This allows the adjustment seat to flexibly adjust the polarimeter's angle, adapting it to samples of different shapes and sizes, expanding the polarimeter's applicability, and improving the device's practicality.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] Example:

[0024] Please combine Figure 1-4 The embodiment of the optical rotator angle precision adjustment seat includes a support plate 1, an adjustment component 2 is provided on the top of the support plate 1, an optical rotator 3 is provided on the inner wall of the adjustment component 2, the top of the support plate 1 is fixedly connected to the connecting seat 4, a sodium lamp 5 is provided on the top of the inner wall of the connecting seat 4, and the bottom of the support plate 1 is fixedly connected to the support foot 6.

[0025] Adjustment assembly 2 includes a fixed plate 201. A sliding groove 202 is formed on the inner wall of the fixed plate 201. A limiting rack groove 203 is formed at the end of the sliding groove 202 away from the optical rotator 3. A limiting rack ring 204 is meshed with the inner wall of the limiting rack groove 203. A connecting post 205 is slidably connected to the inner wall of the limiting rack ring 204. A limiting groove 206 is formed on the inner wall of the end of the connecting post 205 away from the optical rotator 3. A spring 207 is fixedly connected to the end of the connecting post 205 near the limiting groove 206. A pressing shell 208 is fixedly connected to the end of the spring 207 away from the connecting post 205. A sliding post 209 is fixedly connected to the inner wall of the pressing shell 208. A connecting sleeve 210 is fixedly connected to the end of the connecting post 205 away from the spring 207. The two pressing shells 208 and the spring 207 are then pressed together. The compression causes the sliding column 209 to slide along the inner wall of the limiting groove 206, disengaging the limiting rack ring 204 from the limiting rack groove 203. Then, rotating the pressing shell 208 through the limiting groove 206 causes the connecting column 205 to rotate the polarizer 3 inside the connecting sleeve 210, thus adjusting the angle of the polarizer 3 to the desired position. Releasing the pressure on the two pressing shells 208 causes the spring 207 to extend, allowing the pressing shell 208 to re-engage the limiting rack ring 204 with the limiting rack groove 203, thereby fixing the adjusted angle of the polarizer 3. This allows the adjusting seat to flexibly adjust the angle of the polarizer 3, adapting it to samples of different shapes and sizes, expanding the polarizer's applicability and improving the device's practicality.

[0026] There are two fixing plates 201, which are symmetrically distributed around the support plate 1.

[0027] The surface of the limiting rack ring 204 is slidably connected to the inner wall of the sliding groove 202.

[0028] The surface of the pressing shell 208 is slidably connected to the inner wall of the fixing plate 201.

[0029] The end of the pressing shell 208 near the connecting post 205 is fixedly connected to the surface of the limiting rack ring 204.

[0030] The surface of the sliding column 209 is slidably connected to the inner wall of the limiting groove 206.

[0031] The implementation principle of a gyroscope angle precision adjustment seat in this application embodiment is as follows: When using the gyroscope angle adjustment seat, first place the gyroscope 3 into the connecting sleeve 210, then place the sodium lamp 5 onto the connecting seat 4, and then compress the two pressing shells 208 and springs 207 accordingly. The sliding column 209 slides along the inner wall of the limiting groove 206, causing the limiting rack ring 204 to disengage from the limiting rack groove 203. Then, rotating the pressing shell 208 through the limiting groove 206 causes the connecting column 205 to move accordingly. The polarizer 3 inside the sleeve 210 rotates, thereby adjusting the angle of the polarizer 3 to the desired position. Then, the pressure on the two pressing shells 208 is released, causing the spring 207 to extend. This causes the pressing shell 208 to drive the limiting rack ring 204 to re-engage with the limiting rack groove 203, thereby fixing the adjusted angle of the polarizer 3. This allows the adjusting seat to flexibly adjust the angle of the polarizer 3, making it adaptable to samples of different shapes and sizes, expanding the applicability of the polarizer and improving the practicality of the device.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
