Description

Technical Field

[0001] The present application relates to the field of optical prisms, and in particular to an optical prism that is easy to disassemble and install. Background Art

[0002] A prism is an optical element that bends light at a specific angle between the outgoing and incident light. In the optical path, the prism has the function of changing the angle between the outgoing and incident light, shifting the light, and changing the direction of the image. Prisms are widely used in laser research, laser optical systems, biomedicine and other fields.

[0003] Publication No. CN 219245839 U discloses a composite optical prism that is easy to disassemble and install. The clamping mechanism is provided so that when the fixing mechanism fixes the position of prism bodies of different sizes, the column slides inside the circular hole, so that the clamping plate can clamp the outer side of the corners of the prism bodies of different sizes, thereby helping to stabilize the position of the prism body on the upper surface of the circular plate.

[0004] However, there are some defects in the above scheme: although the fixing mechanism and the clamping mechanism are set in the above scheme to clamp and fix the prism, when the prism is disassembled and assembled, it is necessary to manually pull the fixing mechanism one by one, and the prism must be placed in the middle to achieve clamping and fixing. This is difficult for a single person to complete, and it is not very convenient for disassembly and assembly. If the prism is directly pulled out during disassembly, it may cause wear.

[0011] In a specific implementation manner, the lifting block and the inner wall of the vertical groove plate are clearance-matched, and a hand wheel is provided at the top end of the threaded shaft.

[0018] In the above implementation process, the moving block and the positioning block are matched to each other to ensure that the connection plate is installed at a correct angle during installation.

[0019] In a specific implementation manner, the connection plate is provided with a trapezoidal groove, and the elastic clamping member is arranged in the trapezoidal groove.
