Description

Technical Field

[0001] The utility model relates to the field of test workbenches, in particular to a test workbench which is convenient for angle adjustment. Background Art

[0002] The test bench is a platform device specially used for various tests, research, testing, etc. The test bench is one of the indispensable and important equipment in the laboratory. It provides a stable, safe and efficient working environment for the experimenters and promotes the smooth progress of scientific research and experimental work. In the existing patent application with application number CN201821279153.4, an angle-adjustable physics teaching test bench is proposed. When adjusting the angle of the test bench, it is necessary to first rotate the rotating ring by the handle to make the rotating ring move upward along the lifting thread, so that the rotating ring pushes the top block and the sliding through hole to move upward, and then the sliding through hole lifts the test bench and the rotating rod, releasing the restriction on the rotation of the test bench by the annular rack and the clamping block, and then the test bench can be rotated to adjust the angle. When the angle of the test bench is adjusted, it is necessary to rotate the rotating ring in the opposite direction, and the rotating ring moves downward. The top block and the sliding through hole are subjected to the pressure of the test bench and move downward with the rotating ring. The annular rack and the clamping block are clamped, and finally the rotation of the test bench is restricted. This process is relatively complicated, which will not be convenient for adjusting the angle of the test bench, and will make the adjustment efficiency of the angle of the test bench low, so it needs to be improved.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] By setting up a supporting structure, a connecting structure and a fixing structure, when it is necessary to adjust the angle of the upper test bench, the fixing structure can be pushed downward first, so that the plug plate can be disengaged from the fixing slot, and then the upper test bench and the connecting structure can be rotated one hundred and eighty degrees to complete the adjustment of the angle of the upper test bench. Finally, the fixing structure can be loosened, so that the plug plate can be inserted into the fixing slot under the elastic force of the spring. At this time, the upper test bench will be fixed, and the adjustment process is relatively simple, so that the angle of the upper test bench can be more convenient, and ultimately the efficiency of the angle adjustment of the upper test bench can be improved.
