The invention discloses a single prism group with the angle adjustable, and belongs to the technical field of optical detection devices. The single prism group with the angle adjustable aims to solve the technical problems that angle adjustment of a prism assembly in the prior art is inconvenient, and the prism assembly is low in adjustment accuracy. The single prism group with the angle adjustable comprises a base, a bracket and a prism assembly. The prism assembly comprises a prism hood and a prism arranged in the prism hood, wherein the prism and the prism hood are coaxially arranged. The left side and the right side of the prism hood are provided with connection lugs respectively. The connection lug on the left side is connected with the bracket through a pin shaft in a mode of rotating relative to the bracket, and the connection lug on the right side is connected with the bracket through a rotating shaft in a mode of rotating relative to the bracket. One end of the rotating shaft is connected with the connection lug on the right side through keys, and the other end of the rotating shaft penetrates through and stretches out of the bracket and is connected to a rotary knob for the angle adjustment. A dial for indicating rotation angles is further arranged on the bracket. According to the single prism group with the angle adjustable, slant angles of the prism assembly can be adjusted by rotating the rotary knob clockwise or counterclockwise, operation is simple and easy, the angle adjustment is controllable, and the dial is arranged so that the angle adjustment is accurate and readable.
Description
technical field [0001] The invention relates to an angle-adjustable single prism group, which belongs to the technical field of optical detection equipment. Background technique [0002] The single prism group in the prior art includes a base, a connector, a bracket and a prism assembly, and the left and right sides of the prism assembly are relatively rotatably connected to the bracket through pin shafts, and the bracket is connected to the connector. When adjusting the angle of the prism assembly, the prism assembly is manually moved, and the prism assembly rotates with the pin shaft as the axis, so as to achieve the purpose of angle adjustment. The adjustment angle of the manual toggle prism assembly is inconvenient to operate, and the angle adjustment accuracy is low, requiring multiple adjustments to meet the requirements. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, provide an angle-adjusta...
