Description

Technical Field

[0001] The present invention relates to the technical field of swing arm support frames for visual products such as microscopes, and particularly to an adjustable pressure anti-shake microscope swing arm support with flexible use. Background Art

[0002] The microscope swing arm is an important component in the microscope system, used to support and position the optical components of the microscope so that operators or researchers can perform fine observations and operations on samples.

[0003] From the perspective of structural construction, the swing arm is usually a movable device with multiple joints that allows users to adjust the position and field of view of the microscope in different directions and angles. The swing arm can adjust the height of the microscope according to the user to adapt to different working conditions and the height of the user, because different observation tasks may require different working heights to ensure that the operator can comfortably use the microscope.

[0004] In the actual use of existing microscope swing arms, most of them need to move the device to the area where it is needed and then install and fix the selected microscope. However, since most microscope swing arms are multi-sectioned and the weights of different microscopes vary, it may lead to instability and easy shaking of the device during actual use.

[0005] For example, the patent with the application number CN202420633732.3 and the patent name "An Adjustable Surgical Microscope Swing Arm" specifically discloses an adjustable surgical microscope swing arm, including a moving base. The upper surface of the moving base is fixedly connected with a support column, and a plurality of through holes are formed in the interior of the support column. The bottom of the inner wall of the support column is rotatably connected with a threaded rod, the upper end of the threaded rod is fixedly connected with a first bevel gear, and a rotating rod is rotatably connected in the interior of the support column. One end of the rotating rod is fixedly connected with a second bevel gear. In this utility model, by rotating the adjusting block, the fixing plate drives the second bevel gear to rotate, thereby achieving the effect of driving the second bevel gear and the first bevel gear to mesh and rotate. Then, through the rotation of the first bevel gear, the effect of driving the outer wall bracket of the threaded sleeve to slide on the inner wall of the through hole is achieved. By the bracket pushing the stabilizing block to contact the ground, the effect of facilitating the stabilization of the swing arm is achieved, and the stability of the swing arm placement is improved.

[0006] The above hovering support structure has the problem of easy shaking in actual use. Based on this, targeted improvements and enhancements are needed. Summary of the Invention
