Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical instrument brackets, in particular to an optical instrument switching and fixing bracket. Background Art
[0002] Optical instruments are instruments that can generate light waves and display images, or receive light waves and analyze and determine their light properties. Common optical instruments include telescopes, riflescopes, magnifying glasses, night vision goggles, etc. However, some optical instruments are too heavy to be held in the hand for a long time, and are usually fixed using a tripod. Since the tripod cannot be directly mounted on the optical instrument, an adapter bracket is usually installed on the top of the tripod to fix the optical instrument. However, the existing adapter bracket is only used to fix the middle position of the optical instrument, but cannot support the lens barrel of the optical instrument, causing the optical instrument to shake easily. At the same time, during use of the optical instrument, the lens barrel will slowly sag under the action of the weight of the lens barrel, thereby affecting the user's observation effect and making it unfavorable for use. Therefore, an optical instrument adapter fixing bracket is proposed. Utility Model Content

During the rotation of the second threaded rod 13, the moving block 14 and the support plate 15 will be driven to the left, so that the support plate 15 is moved to the bottom of the optical instrument barrel. Then, the servo motor 81 can be started to drive the worm 83 to rotate, and then the first threaded rod 6 is driven to rotate through the worm gear 84. During the rotation of the first threaded rod 6, the moving block 14 and the support plate 15 will be driven to the left, so that the support plate 15 is moved to the bottom of the optical instrument barrel. The mounting block 7 and the support plate 15 move upward as a whole until the rubber pad 16 fits with the bottom of the lens barrel, thereby providing auxiliary support for the lens barrel to avoid shaking or sagging, thereby ensuring the normal use of the optical instrument. This solves the problem that the existing adapter frame is only used to fix the middle position of the optical instrument but cannot support the lens barrel of the optical instrument, resulting in the optical instrument being prone to shaking. At the same time, during the use of the optical instrument, the lens barrel will slowly sag under the action of the weight of the lens barrel, which will affect the user's observation effect and be detrimental to use.
