Double-spring anti-balance device

Abstract

The invention discloses a double-spring anti-balance device, which comprises a bottom plate, a left bracket, a right bracket, a spring box and a spring box cover, wherein the left bracket and the right bracket are fixed on the left side and the right side of the bottom plate; the spring box and the spring box cover have hollow structures, the spring box and the spring box cover are arranged between the left bracket and the right bracket, and the spring box cover is fixed on the spring box; after the spring box cover and the spring box are matched, the left and right sides of the spring box cover and the spring box are provided with a bearing mounting hole respectively, and a bearing is nested into the bearing mounting hole; a concave spring shaft is sleeved in the bearing close to a left supporting plate, and the part of the concave spring shaft outside the spring box is fixed with the left supporting plate; and a convex spring shaft is sleeved in the bearing close to a right supporting plate, and the part of the convex spring shaft outside the spring box is fixed with the right supporting plate. The double-spring anti-balance device is connected with the lifting part of a microscope, so that the lifting part of the microscope overcomes self weight in an effective space range, the accurate lifting of the lifting part is ensured and the connection stability is also improved.

Description

technical field [0001] The invention relates to a microscope component, in particular to a double spring anti-balance device. Background technique [0002] At present, the microscopes used to observe the microscopic world of matter in medicine, scientific research, teaching, etc. generally use coarse and micro coaxial transmission to realize the lifting part of the microscope. However, since the lifting part of the microscope weighs 20kg, the general coarse and micro When the transmission is used for lifting, heavy objects act on the gears, and the gears will slip or break teeth, making it impossible to lift accurately. Contents of the invention [0003] The object of the present invention is to provide a double-spring anti-balance device that can ensure that the lifting part of the microscope can go up and down accurately in order to solve the above-mentioned deficiencies in the prior art. [0004] In order to achieve the above object, the double spring anti-balance devi...
