Description

Technical Field

[0001] This utility model belongs to the technical field of spectrophotometers, and in particular relates to a multifunctional spectrophotometer. Background Technology

[0002] In numerous fields such as modern scientific research, industrial production, and environmental monitoring, spectrophotometers play an irreplaceable role as crucial instruments capable of accurately analyzing the spectral characteristics of substances. Through precise measurement and analysis of light signals, they provide critical data support for substance composition identification and concentration detection.

[0003] However, existing spectrophotometers face numerous problems in practical use. Firstly, due to their intricate internal structure, they are relatively weak against external interference. During handling, installation, and daily use, they are easily damaged by external impacts and vibrations, leading to decreased measurement accuracy or even malfunction. This not only affects experimental and production schedules but also incurs high maintenance costs. Secondly, during operation, existing spectrophotometers typically rely solely on their own weight to rest on the worktable, lacking effective securing measures. If operators accidentally touch the worktable, or in vibrating environments, the instrument is prone to sliding or falling, causing serious damage and potentially leading to accidents and greater losses. Furthermore, existing spectrophotometers generally only allow for the detection of one sample at a time, reducing detection efficiency.

[0004] Therefore, designing a device that can effectively protect the spectrophotometer from external impact damage, while also securely fixing it to the worktable during use, and enabling multiple batches of tests at once, has become a pressing technical problem. To address this, we provide a multifunctional spectrophotometer to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional spectrophotometer, which solves the problems of existing spectrophotometers lacking protective structures and adsorption fixing structures, making them prone to falling and having low detection efficiency, through the cooperation of protective components, vacuum adsorption components, and multi-station components.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a multifunctional spectrophotometer, comprising a spectrophotometer body and a protective assembly. The spectrophotometer body is placed within the inner cavity of the protective assembly. A vacuum adsorption assembly is fixedly connected to the bottom of the spectrophotometer body. A multi-station assembly is fixedly connected to the inner cavity of the spectrophotometer body. The protective assembly includes a housing and a cover, which are connected by a hinge. Buffer cotton is fixedly connected to the inner wall of the housing. The vacuum adsorption assembly includes a vacuum adsorption machine fixedly connected to one side of the spectrophotometer body. Vacuum adsorption plates are fixedly connected to both the front and rear ends of the bottom of the spectrophotometer body. A vacuum pipe connects the vacuum adsorption plates and the vacuum adsorption machine. The multi-station assembly includes a servo motor fixedly connected to the inner cavity of the spectrophotometer body. A lead screw is fixedly connected to the output shaft of the servo motor. A moving rod is threaded onto the surface of the lead screw. A rotary motor is fixedly connected to the other end of the moving rod. A limit rod is fixedly connected to the other side of the bottom of the rotary motor. A sliding rod is slidably connected to the inner cavity of the limit rod. A placement cylinder is fixedly connected to the output shaft of the rotary motor.

[0008] The present invention is further configured such that each of the four corners of the bottom of the spectrophotometer body is fixedly connected to a support leg, and the bottom of the support leg is provided with anti-slip texture. When the instrument is not fixed by the vacuum adsorption component, the support leg with anti-slip texture can effectively increase the friction with the placement surface, prevent the instrument from sliding due to slight external force, and play a preliminary stabilizing support role.

[0009] The present invention is further configured such that the other side of the box body and the box cover are connected by a snap fastener, and handles are fixedly connected to the front and back of the box body. The snap fastener connection facilitates the quick opening and closing and locking of the box cover, ensuring the safety of the instrument inside the box body; the handles on the front and back of the box body make it easy for operators to move the entire device, improving the ease of use.

[0010] The present invention is further configured such that the housing includes an outer shell and an inner liner, a buffer rubber block is fixedly connected between the outer shell and the inner liner, and a buffer spring is fixedly connected between the outer shell and the inner liner and between the two buffer rubber blocks. The buffer rubber block and the buffer spring constitute a double buffer structure, which greatly enhances the housing's ability to absorb and disperse external impact forces, and provides more reliable protection for the instrument.

[0011] The present invention is further configured such that a storage battery is fixedly connected to the other side of the spectrophotometer body. The storage battery provides an independent power supply for the instrument and components such as the vacuum adsorption machine, eliminating the dependence on external power and enabling the instrument to work normally in an environment without external power, thus expanding the application scenarios.

[0012] The present invention is further configured such that a pressure relief valve is fixedly connected to the other side of the vacuum adsorption plate. The pressure relief valve can quickly release the vacuum pressure in the vacuum adsorption plate when the instrument needs to be moved, so as to facilitate the release of the adsorption and fixation state between the instrument and the work surface and improve the ease of operation.

[0013] The present invention is further configured such that a protective cotton is fixedly connected to the side of the box cover that contacts the spectrophotometer body. When the box cover is closed, the protective cotton can further buffer the pressure and impact from above, and protect the top components of the instrument in all directions.

[0014] The present invention is further configured such that an installation groove is provided on the inner wall of the placement cylinder, and a clamping plate is provided in the inner cavity of the installation groove. Tension springs are fixedly connected to the four corners of one side of the clamping plate located on the inner wall of the installation groove. The other end of the tension spring is fixedly connected to the inner wall of the installation groove. The cooperation of the installation groove, the clamping plate and the tension spring can clamp and fix sample containers of different sizes, thereby improving its ease of use.

[0015] The present invention has the following beneficial effects.

[0016] 1. The housing of this utility model adopts a double-layer structure of outer shell and inner liner. The buffer rubber block and buffer spring set between the two can effectively absorb and disperse the impact force generated by external collisions and vibrations, reducing the impact on the precision components inside the instrument. The buffer cotton and protective cotton connected to the inner walls of the housing and the cover respectively further fill the gap between the instrument and the protective components, preventing the internal components from being displaced or bumped during transportation or accidental collisions. This maximizes the integrity of the instrument's core optical components and circuit modules, extends the instrument's service life, reduces maintenance costs, and ensures that the instrument can maintain high-precision measurement performance even in complex operating environments.

[0017] 2. The vacuum adsorption component of this utility model significantly enhances the stability of the spectrophotometer during operation. The vacuum adsorption unit is connected to the vacuum adsorption plate through a vacuum pipe, which can quickly create a vacuum environment on the adsorption plate and the worktable surface, generating a strong adsorption force to firmly fix the instrument on the worktable. Even if the operator accidentally touches it or the working environment vibrates, it can prevent the instrument from sliding or falling, effectively reducing the risk of instrument damage caused by accidental movement. At the same time, the anti-slip textured legs at the four corners of the bottom of the spectrophotometer further increase the friction with the placement surface. Working together with the vacuum adsorption component, it ensures the instrument is placed stably from both multi-point support and adsorption fixation aspects, providing a safe and reliable operating environment for the operator and ensuring the smooth progress of the testing work.

[0018] 3. The multi-station component of this utility model can place multiple test samples at one time for batch testing, improving testing efficiency. At the same time, the servo motor, lead screw and moving rod are set to move the station to the outside of the spectrophotometer body to clean the placement cylinder, which can prevent impurities from falling into the inner cavity of the spectrophotometer body, improve the cleanliness of the spectrophotometer body and improve the accuracy of the test results.

[0029] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example 1

[0031] Please see Figure 1-8 This utility model relates to a multifunctional spectrophotometer, comprising a spectrophotometer body 1 and a protective assembly 2. The spectrophotometer body 1 is placed inside the protective assembly 2. A vacuum adsorption assembly 3 is fixedly connected to the bottom of the spectrophotometer body 1. A multi-station assembly 4 is fixedly connected to the inner cavity of the spectrophotometer body 1. The protective assembly 2 includes a housing 21 and a cover 22, which are movably connected by a hinge. A cushioning cotton 23 is fixedly connected to the inner wall of the housing 21. The vacuum adsorption assembly 3 includes a vacuum adsorption machine 31 fixedly connected to one side of the spectrophotometer body 1. Vacuum adsorption plates 32 are fixedly connected to both the front and rear ends of the bottom of the instrument body 1. Vacuum adsorption plates 32 are connected to vacuum adsorption machine 31 by a vacuum pipe 33. The multi-station component 4 includes a servo motor 41 fixedly connected to the inner cavity of the spectrophotometer body 1. The output shaft of the servo motor 41 is fixedly connected to a lead screw 42. A moving rod 43 is threadedly connected to the surface of the lead screw 42. A rotary motor 44 is fixedly connected to the other end of the moving rod 43. A limit rod 45 is fixedly connected to the other side of the bottom of the rotary motor 44. A slide rod 46 is slidably connected to the inner cavity of the limit rod 45. A placement cylinder 47 is fixedly connected to the output shaft of the rotary motor 44.

[0032] Specifically: The spectrophotometer body 1 is placed inside the protective component 2. The inner cavity is precisely designed to fit the size of the instrument body, ensuring that the instrument is stably placed inside the protective component 2. The vacuum adsorption component 3 is used to achieve a stable connection between the instrument and the work surface. The box 21 and the box cover 22 are connected by a hinge that can be opened and closed flexibly, which facilitates the handling of the instrument. The inner wall of the box 21 is fully covered with soft cushioning cotton 23 with good cushioning performance. When the instrument is placed inside, it can fit tightly against the surface of the instrument and cushion any possible external impacts.

[0033] Example 2

[0034] Please see Figure 1-8Based on Embodiment 1, the four corners of the bottom of the spectrophotometer body 1 are fixedly connected to support legs, and the bottom of the support legs is provided with anti-slip texture. The other side of the box body 21 and the box cover 22 are movably connected by a buckle. The front and back of the box body 21 are fixedly connected to handles 24. The box body 21 includes an outer shell 211 and an inner liner 212. A buffer rubber block 213 is fixedly connected between the outer shell 211 and the inner liner 212. A buffer is fixedly connected between the outer shell 211 and the inner liner 212 and between the two buffer rubber blocks 213. A battery 34 is fixedly connected to the other side of the spectrophotometer body 1, and a pressure relief valve is fixedly connected to the other side of the vacuum adsorption plate 32. Protective cotton is fixedly connected to the side of the cover 22 that contacts the spectrophotometer body 1. An installation groove 48 is opened on the inner wall of the placement cylinder 47. A clamping plate 49 is provided in the inner cavity of the installation groove 48. Tension springs 410 are fixedly connected to the four corners of one side of the clamping plate 49 located on the inner wall of the installation groove 48. The other end of the tension spring 410 is fixedly connected to the inner wall of the installation groove 48.

[0035] Specifically: the anti-slip legs effectively increase friction with the surface when the instrument is not secured using the vacuum adsorption assembly 3, preventing slippage due to slight external forces and providing initial stability. The snap-fit ​​connection facilitates quick opening and closing and locking of the cover 22, ensuring the instrument's safety within the housing 21. Handles 24 on the front and back of the housing 21 facilitate handling and improve usability. The buffer rubber block 213 and buffer spring 214 form a double buffer structure. When the outer shell 211 is impacted, the buffer rubber block 213 and buffer spring 214 are compressed. Due to their elastic potential energy, the buffer rubber block 213 and buffer spring 214 weaken and buffer the impact force, achieving buffering. The protective function greatly enhances the absorption and dispersion of external impact forces by the housing 21, providing more reliable protection for the instrument. The battery 34 provides an independent power supply for the instrument and components such as the vacuum adsorption machine 31, eliminating dependence on external power and enabling the instrument to work normally in environments without external power, thus expanding its application scenarios. The pressure relief valve can quickly release the vacuum pressure in the vacuum adsorption plate 32 when the instrument needs to be moved, making it easy to release the adsorption and fixation state between the instrument and the workbench, improving the ease of operation. When the housing cover 22 is closed, the protective cotton can further buffer the pressure and collision from above, providing all-round protection for the top components of the instrument. The cooperation of the mounting slot 48, the clamping plate 49 and the tension spring 410 can clamp and fix sample containers of different sizes, improving its ease of use.

[0036] The working principle of this utility model is as follows: When the instrument is not in use, the spectrophotometer body 1 is placed inside the housing 21 of the protective component 2, and the housing cover 22 is closed by hinges. The housing 21 and housing cover 22 are locked together by buckles. At this time, the cushioning cotton 23 on the inner wall of the housing 21, the protective cotton on the inner wall of the housing cover 22, and the double-layer cushioning structure of the housing 21 together provide comprehensive protection for the instrument, preventing damage from collisions during transportation and storage. When the instrument needs to be used, the housing cover 22 is opened, the instrument is taken out, and placed on a suitable workbench. The vacuum adsorption machine 31 is started. The vacuum adsorption machine 31 extracts the air between the vacuum adsorption plate 32 and the workbench through the vacuum pipe 33, creating a vacuum environment between the adsorption plate and the workbench, generating a strong adsorption force that firmly fixes the instrument to the workbench; simultaneously, the bottom... The support legs with anti-slip texture also make close contact with the table surface to enhance stability. After use, the pressure relief valve is opened to release the vacuum pressure in the vacuum adsorption plate 32, release the adsorption fixation, and the instrument can be put back into the protective component 2 for proper storage. At the same time, by placing sample vessels in the inner cavity of the placement cylinder 47 and clamping and fixing sample vessels of different sizes by the set tension spring 410, the placement cylinder 47 can be rotated by the rotary motor 44 to perform rotary batch testing. When it is necessary to clean the inner cavity of the placement cylinder 47, the servo motor 41 is started to drive the lead screw 42 to rotate, the lead screw 42 drives the moving rod 43 to move, the moving rod 43 drives the rotary motor 44 to move, and the rotary motor 44 can move the placement cylinder 47 to the outside of the spectrophotometer body 1 for cleaning.
