Description

Technical Field

[0001] This utility model relates to the field of physical technology, and in particular to an ultraviolet-visible spectrophotometer with drop protection function. Background Technology

[0002] As an important analytical instrument in scientific research, quality inspection, environmental monitoring and other fields, the ultraviolet-visible spectrophotometer achieves accurate analysis of sample composition and concentration by measuring the absorbance of substances in the ultraviolet-visible light band. It integrates core components such as a sophisticated optical system, photoelectric conversion elements and electronic circuits. These components are extremely sensitive to vibration and impact. Even a slight impact may cause displacement of optical elements, deviation of optical path or damage to circuits, thereby affecting the accuracy of the test results or even causing instrument failure.

[0003] Accidental drops or collisions are difficult to completely avoid during the use, handling, and storage of instruments. Currently, some spectrophotometers use a full-shell enclosure or simple rubber feet at the bottom for protection. However, while the full-shell enclosure can provide some protection, it cannot provide key protection for the most vulnerable parts, such as the corners of the instrument. Furthermore, the enclosure is not effective in cushioning when subjected to a large impact. Traditional rubber feet can only provide some anti-slip function when the instrument is placed normally. In the event of a drop, they cannot effectively protect the corners of the instrument, thus reducing the practicality of the equipment. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a UV-Vis spectrophotometer with drop protection function. This solves the problem that although the overall shell can provide some protection, it cannot provide key protection for the most vulnerable parts of the instrument, such as the corners, and the shell is difficult to effectively cushion when subjected to a large impact. Traditional rubber feet can only play a certain role in preventing slippage when the instrument is placed normally, and cannot effectively protect the corners of the instrument when it is dropped, thus reducing the practicality of the equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a UV-Vis spectrophotometer with drop protection function, comprising a UV-Vis spectrophotometer, wherein the UV-Vis spectrophotometer is provided with four protective devices; The protective device includes a protective sleeve and a protective pad. The protective pad is fixedly installed on the lower outer wall of the protective sleeve. T-shaped block grooves are opened on the four outer corners of the lower end of the UV-Vis spectrophotometer. T-shaped blocks are fixedly connected inside the protective sleeve. The four T-shaped block slots each have two first limiting block slots inside. The outer walls on both sides of the T-shaped block each have a second limiting block slot. The inner walls of the second limiting block slots each have two limiting blocks slidably connected. The lower outer wall of the second limiting block slot has a pushing block slot. The inner walls of the pushing block slot each have two pushing blocks slidably connected. The inner walls of the pushing block slots each have three reset springs. The four protective devices are located below the four corners of the UV-Vis spectrophotometer and are used in conjunction with each other.

[0006] Preferably, the protective sleeve is L-shaped; The outer wall of the T-shaped block is slidably connected to the interior of the corresponding T-shaped block groove.

[0007] Preferably, the ends of the two limiting blocks near the first limiting block groove both slide into the interior of the T-shaped block groove and respectively contact the inner wall of the corresponding first limiting block groove.

[0008] Preferably, the interior of both second limiting block grooves communicates with the interior of the pushing block groove; The two pushing blocks extend into the groove of the second limiting block at the end closest to the limiting block and are fixedly connected to the outer wall of the corresponding limiting block.

[0009] Preferably, the two ends of the three reset springs are fixedly connected to the outer wall of the corresponding push block.

[0010] Preferably, the ultraviolet-visible spectrophotometer is equipped with a control panel at its upper end, and rubber limit blocks are provided inside the four push block slots; The four rubber limiting blocks have their ends in contact with the outer walls of the corresponding pushing blocks, and one side of the outer wall of each of the four limiting blocks is inclined.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This UV-Vis spectrophotometer with drop protection features a protective device that allows the protective pad to first contact the external object when the instrument is subjected to accidental collisions, drops, or other impacts. The pad absorbs the impact force through its own elastic deformation, reducing the impact on the instrument. At the same time, the protective cover can also resist some impacts through its own structure, further protecting the instrument. This effectively protects the edges and corners of the instrument while improving the practicality and service life of the equipment. Attached Figure Description

[0018] Please see Figure 1-4 This utility model provides a technical solution: a UV-Vis spectrophotometer with drop protection function, including a UV-Vis spectrophotometer 1; The UV-Vis spectrophotometer 1 is equipped with four protective devices; The protective device includes a protective sleeve 4 and a protective pad 5. The protective pad 5 is fixedly installed on the lower outer wall of the protective sleeve 4. The protective sleeve 4 is L-shaped. T-shaped slots 7 are formed on the four outer corners of the lower end of the UV-Vis spectrophotometer 1. T-shaped blocks 13 are fixedly connected inside the protective sleeve 4. The outer wall of the T-shaped blocks 13 is slidably connected to the interior of the corresponding T-shaped slots 7. Two first limiting block slots 6 are formed inside each of the four T-shaped slots 7. Second limiting block slots 8 are formed on the outer walls of both sides of the T-shaped blocks 13. Two limiting blocks 9 are slidably connected inside each of the second limiting block slots 8. The ends of the two limiting blocks 9 closest to the first limiting block slots 6 slide into the interior of the T-shaped slots 7. Each of the two limit block grooves 8 is in contact with the inner wall of the corresponding first limit block groove 6. The lower outer wall of the second limit block groove 8 is provided with a push block groove 12. Two push blocks 3 are slidably connected inside the push block groove 12. The interiors of the two second limit block grooves 8 are connected to the interiors of the push block groove 12. The ends of the two push blocks 3 near the limit block 9 are slidably extended into the interiors of the second limit block grooves 8 and are fixedly connected to the outer walls of the corresponding limit blocks 9. Three return springs 11 are provided inside the push block groove 12. The two ends of the three return springs 11 are fixedly connected to the outer walls of the corresponding push blocks 3. The four protective devices are all located below the four corners of the UV-Vis spectrophotometer 1 and are used in conjunction with each other.

[0019] Among them, the ultraviolet-visible spectrophotometer 1 has a control panel 2 installed on its upper end. Each of the four push block slots 12 is equipped with a rubber limit block 10. The two ends of the four rubber limit blocks 10 are in contact with the outer wall of the corresponding push block 3. One side of the outer wall of each of the four limit blocks 9 is inclined.

[0020] Furthermore, when using this device, if the UV-Vis spectrophotometer 1 is in normal use or under storage, the four protective devices are installed at the four corners of the instrument. The protective sleeve 4 is slidably connected to the instrument via the T-block 13 and the T-block groove 7. At this time, under the action of the return spring 11, one end of the limiting block 9 slides into the T-block groove 7 and contacts the inner wall of the first limiting block groove 6, firmly fixing the protective sleeve 4 to the instrument. The protective pad 5 covers the four corners of the instrument. In this way, when the instrument is subjected to accidental collisions, drops, or other impacts, the protective pad 5 first contacts the external object and absorbs the impact force through its own elastic deformation, reducing the impact force on the instrument. At the same time, the protective sleeve 4 can also resist some of the impact through its own structure. To further protect the instrument, when it is necessary to remove the protective sleeve 4, pull the handle on the rubber limit block 10 to remove it from the inside of the push block groove 12. Then push the push block 3, which slides in the push block groove 12, compressing the reset spring 11 and causing the limit block 9 to slide in the second limit block groove 8, so that the limit block 9 exits from the first limit block groove 6, releasing the fixed state of the protective sleeve 4. At this time, the protective sleeve 4 can be pulled out along the direction of the T-shaped block groove 7. After maintenance, the protective sleeve 4 is reinstalled on the instrument. The push block 3 is released, and the reset spring 11 pushes the push block 3 to reset, causing the limit block 9 to re-insert into the first limit block groove 6, realizing the stable connection of the protective device and continuing to provide drop protection for the instrument.

[0021] When the instrument is subjected to accidental collisions, drops, or other impacts, the protective pad 5 first contacts the external object and absorbs the impact force through its own elastic deformation, reducing the impact on the instrument. At the same time, the protective sleeve 4 can also resist some of the impact through its own structure, further protecting the instrument. This effectively protects the edges and corners of the instrument, improves the practicality of the equipment, and extends its service life.

[0022] Structural Description: The UV-Vis spectrophotometer 1 is the core detection device used for UV-Vis spectral analysis of substances. T-shaped slots 7 are opened at the four corners of its lower end to provide a structural foundation for the installation of protective devices. The control panel 2 is installed at the upper end for instrument operation and data display, realizing human-computer interaction. Protective sleeve 4: The protective sleeve 4 is L-shaped, with a T-shaped block 13 fixedly connected inside. The T-shaped block 13 is slidably connected to the T-shaped block groove 7 at the lower end of the UV-Vis spectrophotometer 1, so that the protective sleeve 4 can be installed and removed on the instrument. The protective sleeve 4 can provide physical protection for the four corners of the instrument and resist external impacts. Protective pad 5: Protective pad 5 is fixedly installed on the lower outer wall of protective sleeve 4. The material is usually an elastic cushioning material, such as rubber or silicone. When the instrument is impacted, the protective pad 5 can absorb and buffer the impact force through its own elastic deformation, reduce the force transmitted to the instrument, and protect the precision components inside the instrument. T-block 13: T-block 13 is fixedly connected to the protective sleeve 4. Its outer wall slides in the T-block groove 7. It is a key structure for the installation and positioning of the protective sleeve 4. At the same time, the outer walls on both sides of T-block 13 are provided with second limiting block grooves 8 to provide space for the installation and movement of limiting block 9 and pushing block 3. Limiting block 9: Two limiting blocks 9 are slidably connected in each second limiting block groove 8. The outer wall of one side of the limiting block 9 is inclined. When one end of the limiting block 9 slides into the T-shaped block groove 7 and contacts the inner wall of the first limiting block groove 6, the protective sleeve 4 can be firmly fixed on the instrument to prevent the protective sleeve 4 from falling off accidentally. Its inclined outer wall design makes it easy to slide under the action of the pushing block 3 to realize the limiting and unlocking functions. Pushing block 3: Pushing block 3 slides in pushing block groove 12, and one end is fixedly connected to limiting block 9. By pushing pushing block 3, limiting block 9 can be driven to slide in the second limiting block groove 8, so that limiting block 9 exits the first limiting block groove 6, thereby releasing the fixed state of protective sleeve 4. After releasing pushing block 3, under the action of reset spring 11, pushing block 3 and limiting block 9 are reset. Reset spring 11: Three reset springs 11 are provided in each push block slot 12. The two ends are fixedly connected to the outer wall of the push block 3. The reset spring 11 provides the push block 3 with the elastic force to reset, ensuring that the limit block 9 can automatically return to the limit state after the unlocking operation, and maintaining the connection stability of the protective device. Rubber limiting block 10: A rubber limiting block 10 is provided in the push block groove 12, with both ends in contact with the outer wall of the push block 3. During the movement of the push block 3, the rubber limiting block 10 plays a buffering and limiting role, preventing the push block 3 from moving excessively, protecting the push block 3, the push block groove 12 and related structures, and avoiding accidental sliding of the push block 3 due to impact, thus ensuring the limiting reliability of the limiting block 9.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
