Description

Technical Field

[0001] The utility model relates to a supporting device, in particular to a vibration-resistant marble base supporting device. Background Art

[0002] With the rapid development of modern science and technology, optical microscopes, as an important precision instrument, play an indispensable role in scientific research fields such as biology, chemistry, physics, and astronomy. The performance of optical microscopes directly affects the accuracy and reliability of experimental results. In order to obtain high-quality imaging effects, experiments usually need to be carried out in a highly airtight environment to reduce the interference of external vibrations and airflow on the experiment.

[0003] Marble is widely used in optical experiments as a material for supporting optical experimental devices due to its good stability, low thermal expansion coefficient and excellent vibration reduction performance. However, traditional marble supporting devices have some problems in practical applications. Due to the processing accuracy, shape and weight limitations of marble, it is often difficult to achieve precise positioning and leveling when marble is used directly as a supporting device, which makes installation and adjustment difficult. In addition, there are certain requirements for the optical experimental cavity, which is a major challenge for high-precision optical experiments that require strict control of environmental conditions.

[0004] There is a lack of specially designed anti-vibration marble base support devices on the market to solve the above problems. Therefore, it is of great significance to develop an anti-vibration marble base support device that can provide precise positioning, fast filling, easy installation and adjustment, and excellent air tightness to improve the experimental performance of precision instruments such as optical microscopes. The design and application of this device will greatly promote the development of related scientific research fields and meet the experimental requirements for high stability and high precision.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The experimental cavity described in this embodiment does not appear in the figure. It can be imagined as a rectangular metal cavity with a flange on the outer surface of the cavity to connect the cavity to the outside world.

[0021] like Figure 1 , Figure 2 The illustrated embodiment shows a vibration-resistant marble base supporting device, wherein the bellows assembly includes a bellows 202 and a flange 201. The fixing assembly includes a supporting column 1, a fixing plate 4 and a fixing bolt 11. The positioning assembly includes a positioner 9, a positioning top column 5 and a top column fixing block 501.

A lower support plate 7 is provided at the upper end of the marble 8, and a top column fixing block 501 is provided on the lower support plate 7. The top column fixing block 501 is installed in a mounting hole of the top column fixing block 501 reserved on the lower support plate 7. The mounting position of the top column fixing block 501 corresponds to the hole reserved for the positioning top column 5 on the upper support plate 6. The positioning top column 5 is a metal top column with a round head. The positioning top column 5 locates the relative position of the upper support plate 6 through the through hole reserved on the upper support plate 6, and is inserted into the upper support plate 6. The support plate 6 and the round head part of the positioning top column 5 are against the top column fixing block 501, and the positioning top column 5 is used to support the outer surface of the experimental chamber; the fixing plate 4 is around the upper support plate 6 and the lower support plate 7, and the upper support plate 6 and the lower support plate 7 are fixed by threaded connection respectively, so as to ensure that the relative height position of the upper support plate 6 and the lower support plate 7 remains unchanged, and the supporting column 1 is installed on the upper support plate 6, and the number of supporting columns 1 installed is determined according to actual needs. The flanges 201 are installed at both ends of the bellows 202 to form a bellows assembly. The bellows assembly vertically sleeves the supporting column 1 in the middle position of the bellows 202, and the flanges 201 at both ends of the bellows 202 are respectively connected to the upper support plate 6 and the experimental chamber.

[0022] During the installation process, the position of the marble 8 can be adjusted by using the positioner 9. During use, the upper end of the positioning top column 5 is against the outer surface of the experimental cavity to ensure the stability of the cavity. The flanges 201 at both ends of the bellows assembly are respectively connected to the upper support plate 6 and the experimental cavity to ensure the airtightness inside the experimental cavity. At the same time, the supporting column 1 installed on the upper support plate 6 is in the bellows assembly and supports the experimental instrument in the cavity. When the experimental instrument vibrates, the vibration is isolated and the vibration is transmitted to the upper support plate 6, and the upper support plate 6 transmits the vibration to the lower support plate 7 and then to the marble 8 to reduce the impact of vibration.
