Abstract
The utility model relates to a kind of self-centering type lens-holding frame.Comprise fixing ring body, double shell, guide rod, block rubber, end sealing, spring, the circumference uniform distribution of described fixing ring body is provided with three double shells, described double shell is be welded on a thick barrel on fixing ring body and a thin barrel, described guide rod is the body of rod that an end band cap one end is bonded with the T-type structure of block rubber, the inner core of described guide rod and double shell is slidably matched, described spring fitting is in double shell, and one end contacts with the end cap of guide rod, and the port end sealing of described double shell screws closed.The utility model is forward and backward flexible under the elastic force effect of spring by arranging guide rod, because guide rod is consistent with the position that spring distributes and structure, therefore under the action of the spring, each guide rod is unanimously stressed, make by the lens self-centering clamped, and what make to contact with lens is block rubber, avoids producing cut to lens surface, there is structure simple, flexibly and easily.
Description
Technical field
The utility model relates to lens mount field, particularly relates to a kind of self-centering type lens-holding frame.
Background technology
In the lens mount structure of prior art except adjustable by except the diameter of retain lenses, without other flexible Application, operation is complete to be relied on manually, and does not have high-precision localization criteria.Therefore, forward and backward flexible under the elastic force effect of spring by arranging guide rod, because guide rod is consistent with the position that spring distributes and structure, therefore under the action of the spring, each guide rod is unanimously stressed, make by the lens self-centering clamped, and what make to contact with lens is block rubber, avoid producing cut to lens surface, have structure simple, flexibly and easily, the lens mount solving prior art relies on the screw-fashion of screw thread the position of lens can not be fixed on central authorities accurately, and fixing slow of the eyeglass regulated, the problem such as longer consuming time.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of self-centering type lens-holding frame is provided, forward and backward flexible under the elastic force effect of spring by arranging guide rod, make by the lens self-centering clamped, and what make to contact with lens is block rubber, avoid producing cut to lens surface, the lens mount solving prior art relies on the screw-fashion of screw thread the position of lens can not be fixed on central authorities accurately, and fixing slow of the eyeglass regulated, the problem such as longer consuming time.
A kind of self-centering type lens-holding frame, comprise fixing ring body, double shell, guide rod, block rubber, end sealing, spring, the circumference uniform distribution of described fixing ring body is provided with three double shells, described double shell is be welded on a thick barrel on fixing ring body and a thin barrel, described guide rod is the body of rod that an end band cap one end is bonded with the T-type structure of block rubber, the inner core of described guide rod and double shell is slidably matched, described spring fitting is in double shell, one end contacts with the end cap of guide rod, and the port end sealing of described double shell screws closed.
Further, the inner core height of described double shell is 1/3rd of urceolus height, the hole of inner barrel is through hole, be used for installing the structure of guide rod and spring, make guide rod forward and backward flexible under the elastic force effect of spring, because guide rod is consistent with the position that spring distributes and structure, therefore under the action of the spring, each guide rod is unanimously stressed, makes by the lens self-centering clamped.
Further, described block rubber is projective table type structure, adopts industrial seccotine to be bonded in the end of guide rod, and what make to contact with lens is block rubber, avoids producing cut to lens surface.
Further, the natural elongation state of adjustable-length from the most compressed state of spring to spring of described guide rod, the stressed lens that make according to spring can regulate in self-centering, and can adapt to the lens of different-diameter.
The utility model provides a kind of self-centering type lens-holding frame, its beneficial effect is: by arrange guide rod under the elastic force effect of spring before, rear flexible, because guide rod is consistent with the position that spring distributes and structure, therefore under the action of the spring, each guide rod is unanimously stressed, make by the lens self-centering clamped, and what make to contact with lens is block rubber, avoid producing cut to lens surface, there is structure simple, flexibly and easily, the lens mount solving prior art relies on the screw-fashion of screw thread the position of lens can not be fixed on central authorities accurately, and fixing slow of the eyeglass regulated, the problem such as longer consuming time.
Accompanying drawing explanation
