Abstract
The utility model relates to a lensmeter used for determining the position of an optical center of a flat astigmatic lens, which comprises a lensmeter body, wherein a base of the lensmeter body is provided with four through holes, each of the through holes is internally provided with an internal thread, one ends of vertical screws used for adjusting the height of the lensmeter body penetrate through the through holes respectively, and the other ends are fixedly connected with a supporting base; the lensmeter body is provided with a bubble level; the lensmeter is further provided with a gooseneck, and the other end of the gooseneck is fixedly connected with a sucker used for sucking the flat astigmatic lens. The lensmeter provided by the utility model solves a problem that a traditional lensmeter cannot clamp when determining the center of the flat astigmatic lens, and has extremely high popularization values.
Description
Technical field
The utility model relates to glasses device field, specifically relates to a kind of for determining the lensmeter of single loose lens optical center.
Background technology
Lens has number of different types, and single loose eyeglass is one wherein, while being usually used in astigmatic people's group configuration glasses, uses.Before configuration glasses, need first to determine with lensmeter the optical centre of convex 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) single loose eyeglass is different from concavees lens and convex lens, because single loose eyeglass is simple cylindrical lens, without concave-sphere luminosity, therefore, the optical centre of single loose eyeglass is not under normal circumstances in the geometric center of eyeglass.In real work, often need to pinch single loose eyeglass and be tilted with hand, then above eyeglass seat, move, could its optical centre.In the time that the mobile cursor of lensmeter screen overlaps with setting cursor, under tapper, be the optical centre of convex lens, be now that available tapper is got central point on convex lens.But get ready in process, hand meeting slight jitter, causes the central point of getting not overlap with actual optical centre.
Although existing lensmeter carries bikini lens clamping device, single loose eyeglass many places in the time determining optical centre, in heeling condition, are not horizontalitys, so the bikini clamping device that lensmeter carries 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 single loose lens optical center.
The utility model adopts following technical proposals:
A kind of for determining the lensmeter of single loose lens optical center, 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 described lensmeter body, be also provided with swan neck, the other end of swan neck be fixedly connected with for the sucker that adsorbs single loose eyeglass.
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 body.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) solved traditional lensmeter and determined when list falls apart lens optical center, the problem that cannot clamp.When use, sucker is adsorbed on single loose eyeglass, then mobile above eyeglass seat.In the time that the mobile cursor of lensmeter screen overlaps with setting cursor, under tapper, be the optical centre of single loose eyeglass, now hand unclamps eyeglass, gets ready.Eyeglass is adsorbed by sucker, and sucker is fixedly connected with swan neck.Swan neck is metal hose, can be significantly bending, distortion, and frangibility not, and can bear the weight of sucker and single loose eyeglass, keep dimensionally stable.
Brief description of the drawings
Fig. 1 is structural drawing of the present utility model;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is application drawing of the present utility model;
Wherein: 1, lensmeter body, 2, louvre, 3, vertical screw, 4, supporting seat, 5, swan neck, 6, sucker, 7, horizontal bubble instrument, 8, single loose eyeglass, 9, eyeglass seat.
Embodiment
Embodiment 1: a kind of for determining the lensmeter of single loose lens optical center, its structure is as shown in Figure 1-2: comprise lensmeter body 1, on the base of described lensmeter body 1, be provided with 4 through holes, in through hole, be provided with internal thread, pass through hole for vertical screw 3 one end that regulate lensmeter body 1 height, the other end is fixedly connected with supporting seat 4; On described lensmeter body, 1 is provided with air-bubble level 7; On described lensmeter body 1, be also provided with swan neck 5, the other end of swan neck 5 be fixedly connected with for the sucker 6 that adsorbs single loose eyeglass; On the shell of described lensmeter body 1, be provided with louvre 2.
This programme can Real Time Observation and is adjusted the levelness of lensmeter body 1.Lensmeter body 1 is positioned on worktable, by the position of bubble in eye-level bubble instrument 7, adjusts the height of corresponding vertical rod 3, guarantee the real-time level of lensmeter body 1.
Meanwhile, solved traditional lensmeter and determined when list falls apart lens optical center, the problem that cannot clamp.When use, sucker 6 is adsorbed on single loose eyeglass, then mobile above eyeglass seat 9.In the time that the mobile cursor of lensmeter screen overlaps with setting cursor, under tapper, be the optical centre of single loose eyeglass 8, now hand unclamps single loose eyeglass 8, gets ready.Eyeglass is adsorbed by sucker 6, and sucker 6 is fixedly connected with swan neck 5.Swan neck 5 is metal hose, can be significantly bending, distortion, and frangibility not, and can bear the weight of sucker 6 and single loose eyeglass 8, keep dimensionally stable.
The sucker of mentioning in the utility model, one end is metal material, the other end is rubber bowl structure.In spectacles industry, the kit of center instrument, at this without detailed description.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendments that creative work can make or distortion still in protection scope of the present invention.
