Abstract
The utility model relates to a lens-meter for determining optical center position of a concave lens, comprising a lens-meter body. A base of the lens-meter body is provided with a through hole, where internal screw threads are disposed. One end of a vertical screw rod traverses through the through hole, and the other end is fixedly connected to a supporting seat. The lens-meter body is provided with a bubble level meter. A push plate of the lens-meter body is provided with an arc-shaped groove, where a left screw rod and a right screw rod are disposed. A left clamping seat for supporting the concave lens is inserted into the arc-shaped groove and is fixedly connected to the right end of the left screw rod, and the left end of the left screw rod traverses through the arc-shaped groove. A right clamping seat for supporting the concave lens is inserted into the arc-shaped groove and is fixedly connected to the left end of the right screw rod. The right end of the right screw rod traverses through the arc-shaped groove. The left screw rod and the right screw rod are respectively provided with a set nut. The lens-meter for determining optical center position of a concave lens is advantageous in that the problem of a conventional lens-meter clamping device that the upper surface of the concave lens will be damaged can be resolved, and popularization value is high.
Description
Technical field
The utility model relates to glasses device field, specifically relates to a kind of for determining the lensmeter of concavees lens optical centre position.
Background technology
Lens has number of different types, and concavees lens are one wherein.The optical mirror slip thin centered by concavees lens, edge is thick, uses during for myopia population configuration glasses.Before configuration glasses, need first to determine with lensmeter the optical centre of concavees lens.
Now the normal lensmeter using exists a lot of not enough: (1) lensmeter base is surface level, can steadily be positioned on table surface.But the level of lensmeter relies on the level of table surface, and himself cannot keep level.In actual use, there is certain gradient in the table top of a lot of worktable, and focal power is counted precision optical instrument, and long-time slant setting can significantly reduce the serviceable life of lensmeter.(2) lensmeter, in the time detecting the optical centre of concavees lens, needs hand-held concavees lens side and it is moved above eyeglass seat, observes the image of lensmeter screen simultaneously.In the time that the mobile cursor of lensmeter screen overlaps with setting cursor, under tapper, be the optical centre of concavees lens, be now that available tapper is got central point on concavees lens.But get ready in process, hand meeting slight jitter, causes the central point of getting not overlap with actual optical centre.(3) although existing lensmeter carries bikini eyeglass fixator, and it is limited to self structure, when use, need to, by the upper surface by being pressed in concavees lens, therefore often can leave 3 small ruts in upper lens surface, cause eyeglass to be scrapped, cannot use.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of for determining the lensmeter of concavees lens optical centre position.
The utility model adopts following technical proposals:
A kind of for determining the lensmeter of concavees lens optical centre position, comprise lensmeter body, on the base of described lensmeter body, be provided with 4 through holes, in through hole, be provided with internal thread, for regulating vertical screw one end of lensmeter body height to pass through hole, the other end is fixedly connected with supporting seat; On described lensmeter body, be provided with air-bubble level; On the pushing plate of described lensmeter body, be provided with circular groove, in circular groove, be provided with left screw rod and right screw rod; Insert circular groove and be fixedly connected with the right-hand member of left screw rod for the left grip slipper that clamps concavees lens, the left end of left screw rod passes circular groove, is provided with left setscrew nut on left screw rod; Insert circular groove and be fixedly connected with the left end of right screw rod for the right grip slipper that clamps concavees lens, the right-hand member of right screw rod passes circular groove, is provided with right setscrew nut on right screw rod.
Preferably, on the shell of described lensmeter body, be provided with louvre.
The beneficial effects of the utility model are: (1) can Real Time Observation and adjusted the levelness of lensmeter.Lensmeter body is positioned on worktable, by the position of bubble in eye-level bubble instrument, adjusts the height of corresponding vertical rod, guarantee the real-time level of lensmeter.(2) axial traditional lensmeter clamping device is changed to radially clamping device, thereby avoided upper lens surface damage.When use, left hand pinches left grip slipper and right grip slipper, and concavees lens are clamped between the two, is then moved to the left, make the optical centre of concavees lens be positioned at the left side of lensmeter setting cursor, then the right setscrew nut of turn, moves right right screw rod, and left and right grip slipper entirety also moves to the right, in the time that the mobile cursor of lensmeter screen overlaps with setting cursor, screw left setscrew nut, concavees lens are steadily clamped between left and right grip slipper the most at last, can carry out optical centre mark.Avoid the error causing because of hand shake.
