Abstract
The utility model relates to a spectacle measuring ruler, and discloses a cross ruler for measuring spectacles. The cross ruler mainly comprises a ruler body, wherein the ruler body is of a cross structure, the ruler body is evenly marked with scales, the ruler section width of the ruler body is 6 mm, and the edges are 3 mm away from the ruler section center; the integral lengths of the ruler body in the horizontal direction and the vertical direction range from 7 to 10 cm; preferably, the integral lengths of the ruler body in the horizontal direction and the vertical direction are 8 cm, the cross ruler is made of transparent plastics, and is of an integral structure. The cross ruler can position the geometric center of the spectacle frame quickly, the ruler section width in the horizontal direction is 6 mm, and the edges are respective 3 mm away from the ruler section center, thus whether the geometric center is within a range of 3 mm above or below an optical center can be quickly judged; and the cross ruler has the advantages of convenient usage and accurate measurement.
Description
Technical field
The utility model relates to a kind of glasses dip stick.
Background technology
Glasses are to correct defects of vision or protect eyes and the simple optical device made, mainly are made up of eyeglass and mirror holder, and mirror holder is the important component part of glasses, mainly plays the effect of support lenses, and rakish spectacle frame can also play effect attractive in appearance.Assembled glasses generally comprises optometry, selects eyeglass, selects mirror holder, step such as polishing and assembling, wants to assemble out suitable oneself glasses, and except will selecting suitable eyeglass and mirror holder, glasses optometry process also is very important.According to the regulation of GB13511-1999, the optical centre of eyeglass should be positioned at up and down 3 millimeters scope of mirror circle geometric center vertical direction, if the lens optical center should mark "+" number before numerical value above the mirror circle geometric center in detection; If the lens optical center should mark "-" number before numerical value below the mirror circle geometric center.The so-called optical centre-height refers to lens optical center and mirror circle geometric center distance in vertical direction.General measuring method is to measure in level and the vertical direction of mirror holder with ruler, finds out the geometric center of mirror holder, measures optical centre then to the vertical range of the geometric center of mirror holder.The problem that adopts this kind method to produce is, because what use is ruler, measure appearance circle geometric center whether at the lens optical center up and down in 3 millimeters the scope, optical centre and geometric center are difficult to disposable measurement and finish, need to measure repeatedly, and measurement result is inaccurate.
Summary of the invention
The purpose of this utility model provides a kind of Cross ruler of measuring glasses, need measure repeatedly when the available technology adopting ruler is measured the optics centre-height to solve, and the inaccurate problem of measurement result.
The utility model mainly comprises the chi body, and solving the technical scheme that its technical matters adopts is that described chi body is decussate texture, and evenly mark has scale on the chi body, 6 millimeters of the chi Duan Kuanwei of chi body, and Edge Distance chi section center is 3 millimeters; The horizontal direction of described chi body and the entire length of vertical direction are 7-10 centimetre.
The horizontal direction of described chi body and the entire length of vertical direction are 8 centimetres.
Described Cross ruler adopts transparent material to make.
Described Cross ruler adopts transparent plastic to make.
Described Cross ruler is integral structure.
The good effect that adopts the utility model to have is: the utility model product can be located the geometric center of mirror holder fast, horizontal direction chi Duan Kuanwei is 6 millimeters simultaneously, geometric center so just can be judged fast whether about optical centre in 3 millimeters the scope in each 3 millimeters at Edge Distance chi section center; The employing transparent material is made, and is cruciform, can the cruciform center be initial point, respectively about, left and right directions mark is the size of unit with the millimeter, and is easy to use, measure accurately.
Description of drawings
Fig. 1 is the synoptic diagram of the optical centre height of expressing of glasses;
Fig. 2 is structural representation of the present utility model;
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-2:
A kind of Cross ruler of measuring glasses mainly comprises chi body 5, and described chi body 5 is decussate texture, and evenly mark has scale 4 on chi body 5,6 millimeters of the chi Duan Kuanwei of chi body 5, and the distance b at Edge Distance chi section center is 3 millimeters; The horizontal direction of described chi body 5 and the entire length of vertical direction are 7-10 centimetre; Preferably, the entire length of the horizontal direction of above-mentioned chi body 5 and vertical direction is 8 centimetres.
Cross ruler adopts transparent material to make, because plastics have in light weight, good toughness, and easy moulding and the low advantage of cost, as a kind of improvement of the present utility model, preferably, above-mentioned Cross ruler adopts transparent plastic to make, transparent plastic transparent good, the anti-wear performance height.
Further, above-mentioned Cross ruler is integral structure, and surface quality is good, thereby can reach the requirement of use.
The using method of the utility model product: as the instrument of the equipped glasses optical centre height h of a kind of quick measurement, adopt this Cross ruler when measuring, energy is positioning mirror circle geometric center 2 fast, when namely needing to measure, aim at eyeglass with Cross ruler, because Cross ruler is decussate texture, above evenly mark scale 4 is arranged, and 6 millimeters of the chi Duan Kuanwei of Cross ruler horizontal direction, correspondingly, two edges are 3 millimeters from the distance b at chi section center, so just can judge fast that appearance circle geometric center 2 is whether at the lens optical center about in the of 1 in 3 millimeters the scope, if it is in the scope of GB13511-1999 regulation, just up to specification; On the contrary, just against regulation.This Cross ruler adopts transparent plastic to make, because transparent plastic has the high grade of transparency, thus can watch size easily, easy to use and measure accurately.
Though described embodiment of the present utility model by reference to the accompanying drawings; but those skilled in the art can make various distortion or modification within the scope of the appended claims; as long as be no more than the described protection domain of claim of the present utility model, all should be within protection domain of the present utility model.
