Description

Technical Field

[0001] The utility model belongs to the technical field of dust-proof protection devices, and particularly relates to a dust-proof protection device for an atomic force microscope. Background Technique

[0002] An atomic force microscope (AFM) is a high-resolution surface analysis tool widely used in the fields of materials science, nanotechnology, biology, and chemistry. The AFM scans the surface of a sample with a probe to obtain surface topography and physical information at the nanoscale. When performing high-precision measurements, the AFM has extremely high requirements for the cleanliness and stability of the environment. To avoid interference from external dust, particulate matter, and vibration on the measurement results, the AFM is usually equipped with a dedicated dust-proof protection device.

The slider 32 in the fixed disk 31 also drives the clamping plates 33 to approach each other, and finally tightly clamps the microscope base to fix it. The setting of the fixing mechanism 3 can ensure that the position of the microscope inside the dust-proof and protection device remains stable, preventing it from moving due to external vibration or operation, thereby ensuring the reliability of the experimental results.

[0037] As shown in Figure 1 and Figure 5 the figure, a damping mechanism 4 is provided on the box body 1. The damping mechanism 4 includes a first damping component and a second damping component;

Through the connection of the belt 38 and the first pulley 37, the connecting column 35 will also rotate. At this time, the square connecting plate 36 rotates and drives the L-shaped connecting rod 34 to rotate and approach each other. The slider 32 in the fixed disk 31 will also drive the clamping plates 33 to approach each other and finally tightly clamp the microscope base to fix it. The setting of the fixing mechanism 3 can ensure the stable position of the microscope inside the dust-proof and protection device, preventing it from moving due to external vibrations or operations, thus ensuring the reliability of the experimental results;

[0045] By providing a vibration damping mechanism 4, when the microscope is operating, external vibrations may affect the observation results.

At the same time, the second sliding column 46 presses the damper 48 and the second spring 49 to slide in the second sleeve 47 on the second fixing plate 45, further enhancing the function of vibration damping. The setting of the vibration damping mechanism 4 can effectively isolate the vibrations in the external environment, preventing these vibrations from being transmitted to the microscope and the measured sample, ensuring the stable operation of the equipment;
