[0002] When using a microscope to observe the surface morphology of an object, the sample must be placed stably and moved and rotated smoothly. When observing the surface morphology of thin-walled pipes, the pipes are often required to rotate and tilt around their central axis. However, the stage of a general microscope is flat. Due to the structural characteristics of the pipe, when it is directly placed on the stage of the microscope for observation and rotation, it will roll, affecting the observation effect, and tilted observation is impossible. How to stably place the pipe to be observed and smoothly rotate the sample at various angles for observation is a technical problem that needs to be solved by technicians in this field. Summary of the invention

[0045] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the device for observing the microscopic morphology of the surface of a thin-walled pipe of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0048] The support mechanism 2 includes an arc-shaped plate 21 with teeth 23 formed on the outer wall, the arc-shaped plate 21 passes through the gap between the upper pressure roller 121 and the lower support roller 122, and the teeth 23 are meshed with the driving gear assembly 13;

[0049] The rotating mechanism 3 is inserted into the thin-walled pipe 5 and includes a rotating shaft assembly 31 and two groups of supporting assemblies 32 arranged thereon. Both ends of the rotating shaft assembly 31 are connected to the arc plate 21 , and the supporting rod 322 of the supporting assembly 32 contacts the inner wall of the thin-walled pipe 5 .

[0050] like Figure 2 As shown, the base mechanism 1 further includes a base 15 fixedly connected to the bottom plate 112 .

[0051] The base shell 11 is composed of a bottom plate 112 and two side plates 111 connected to the bottom plate 112; the length of the bottom plate 112 is smaller than the length of the side plates 111, and the two ends of the transmission component 12 are fixedly connected to the edges of the two side plates 111 respectively to ensure that the transmission component 12 has no contact with the bottom plate 112, so as to ensure the smooth rotation of the lower support roller 122.

[0052] In this embodiment, in order to ensure the stable movement of the supporting mechanism 2 , an annular groove is formed on the outer wall of the lower supporting roller 122 of the transmission assembly 12 to limit the arc plate 21 .

[0053] The driving gear assembly 13 includes a driving shaft 131 and a driving wheel 132 sleeved on the outside of the driving shaft 131, the driving wheel 132 meshes with the teeth 23, the driving shaft 131 is fixedly connected to the rotating crank 14, and a locking assembly 16 is provided on the rotating crank 14. The driving wheel 132 can be rotated by rotating the crank 15, and the rotating crank 14 can be locked by the locking assembly 16 so that it does not rotate, thereby fixing the support mechanism 2 so that it does not rotate.

[0054] The curvature of the circular arc formed by the two lower support rollers 122 and the driving gear assembly 13 is the same as the curvature of the arc plate 21 .

[0055] In this embodiment, in order to protect the support mechanism, extend its service life, and reduce the loss of the teeth due to friction, the lower support roller 122 and the upper pressure roller 121 are rubber-coated rollers with rubber roller surfaces.

The assembly effect diagram is shown in FIG. Figure 1 During observation, the sample can be observed at different circumferential angles by rotating the two damping shafts 32, and the sample can be observed at different angles by shaking the rotating crank 15. At the same time, the rotating crank 15 can be locked by the locking assembly 16 to lock the observation angle. The device can realize smooth and stable observation of thin-walled pipe samples at different angles and in different circumferential directions.

[0063] The present invention uses a support rod to support the thin-walled pipe to be tested in the device. The surface of the sample can be observed in different circular directions and at different angles by rotating the rotating shaft and shaking the rotating crank, and the sample can be fixed at any point, thereby realizing smooth observation of the thin-walled pipe sample.
