Auxiliary device for mounting spectacle lenses

Abstract

The invention discloses an auxiliary device for mounting spectacle lenses. The auxiliary device comprises a bottom plate, and fixing plates are fixed to the two sides of the outer wall of the top of the bottom plate correspondingly. A bidirectional threaded rod is hinged to the inner wall of one side of one fixing plate, and one end of the bidirectional threaded rod penetrates through the other fixing plate to be fixedly provided with a turntable. The outer wall of the bidirectional threaded rod is in threaded connection with two sliding pieces, and fixing blocks are fixed to the outer walls of the tops of the two sliding pieces. Grooves are formed in the middles of the outer walls of the tops of the fixing blocks, and mounting grooves distributed at equal intervals are formed in the innerwalls of the two sides of each groove. When the device is used, the bidirectional threaded rod is driven to rotate by rotating the turntable, the bidirectional threaded rod and the two sliding piecesare in threaded connection fit, then the two sliding pieces move towards or away from each other to adjust the distance between the two fixing blocks so as to fix glasses frames of different lengths,and the whole device is simple in design mechanism, convenient to maintain in the later period and low in cost.

Description

technical field [0001] The invention relates to the technical field of lenses, in particular to an auxiliary device for installing spectacle lenses. Background technique [0002] Lens is a transparent material with one or more curved surfaces made of optical materials such as glass or resin. After being polished, it is often assembled with a spectacle frame to form glasses. It is used to correct the user's vision and obtain a clear vision. When installing, most of them are installed with the frame in one hand and the lens in the other, which is troublesome. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose an auxiliary device for installing spectacle lenses. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] An auxiliary device for eyeglass lens installation, comprising a bottom plate, fixed plates are fixed on both sides o...
