Description

Technical Field

[0001] The utility model relates to the technical field of large-aperture lens installation equipment, in particular to a lens barrel support frame. Background Art

[0002] Large aperture lenses in laboratories and industries require certain angles and fixtures to coordinate with optical system debugging.

[0003] In industry, various support columns and lever mechanisms are conventionally used to adjust the position of platform loads. However, this type of adjustment mechanism often has poor overall stability. Specifically, when a bracket is used to support the lens barrel, the connection position between the bracket and the lens barrel is fixed and cannot be adjusted. As a result, when the size of the lens barrel changes, the center of gravity also changes accordingly. Due to the fixed connection position, the center of gravity of the lens barrel cannot be on the same center line as the center of gravity of the support frame, resulting in poor support effect for the lens barrel and poor overall stability. Utility Model Content

[0004] In order to solve the problems of the prior art, the utility model provides a lens barrel support frame, comprising: a bottom plate;

[0005] A first support frame and a second support frame, wherein the first support frame and the second support frame are both vertically connected to the top end surface of the bottom plate;

[0006] A clamp, the top of the first support frame and the top of the second support frame are both connected with the clamp, and the clamp is used to lock the lens on the first support frame and the second support frame;

[0007] The bottom of the first support frame and the second support frame are both provided with a first waist hole, and the first support frame and the second support frame are connected to the base plate through the first waist hole by fasteners. When the fasteners are free, the support frames can move along the waist holes.

[0008] Furthermore, the tops of the first support frame and the second support frame are both provided with semicircular grooves;

[0009] Two ends of the clamp are respectively connected to two ends of the top of the grooves on the first support frame and the second support frame.

[0010] Furthermore, the clamp is an arc-shaped structure.

[0011] Furthermore, the clamp is a flexible strip structure.

[0012] Furthermore, both ends of the clamp are provided with horizontal connecting parts, the horizontal connecting parts are provided with second waist holes, and the clamp is connected to the first support frame and the second support frame through the second waist holes by fasteners.

[0013] Furthermore, a truss adjustment plate is provided between the end surfaces of the first support frame and the second support frame, and a third waist hole is provided at both ends of the truss adjustment plate. The truss adjustment plate is connected to the first support frame and the second support frame through the third waist hole by fasteners.

[0014] Furthermore, handles connected to the top end surface of the bottom plate are provided on both sides of the first support frame and the second support frame.

[0015] Beneficial effects of the utility model:

[0016] By setting the first support frame and the second support frame in cooperation with the clamp, the position of the lens can be stably limited, and by setting the waist hole, the position of the first support frame and the second support frame can be adjusted when the fastener is free, so as to adapt to the installation and connection of lens barrels of different sizes, thereby making the center of gravity of the lens barrel and the center of gravity of the support frame as a whole tend to be in a straight line, thereby improving the stability of the lens barrel.
