Abstract
The utility model relates to a holding-free magnifier, belonging to a further improvement on magnifiers. The utility model is characterized in that lenses are formed by the combination of a positive and a negative lens plates so that the optical imaging quality of the utility model is superior to the optical imaging quality of a single plate magnifier; the magnifier frame of the positive lens plate is in a screw connection with the magnifier frame of the negative lens plate, and rotation can be carried out for focusing; both ends of each of the magnifier frames are provided with a head belt so that the magnifier can be conveniently worn on a head without requirement of hand holding; targets can be sharply observed by eyes through the magnifier. The utility model has the advantages of convenient use, convenient carrying, simple structure, easy processing, low cost, and strong practicability, being widely suitable for the travel industry, the jewelry industry, etc.
Description
The utility model is a kind of hands-free magnifier, belongs to the further improvement to existing magnifier.
At present, the magnifier of selling on the market has various enlargement ratio, and its structure is that enlarging lens is fixed in the picture frame, and a handle is arranged in the outside of picture frame.During with the magnifier object observing, must hold with hand, target is put near the magnifier front focal plane, and eyes are positioned near the back focal plane of magnifier.This magnifier is because be hand-held, so the inconvenience of using and has bigger optical imaging aberration, and target in (100-1000 millimeter) in the fixed point observation certain distance scope clearly.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art and a kind of hands-free magnifier is provided, and holds without hand, can observe the target in the certain distance scope clear, easily.
The purpose of this utility model can reach by following measure: by picture frame and place the eyeglass of picture frame to form, it is characterized in that two eyeglasses are combined by positive lens sheet and negative lens sheet, for being threaded, there is headband at the picture frame two ends between the picture frame of positive lens and the picture frame of negative lens.
The purpose of this utility model can also reach by following measure: forming the positive lens sheet and the negative lens sheet of eyeglass, can be positive lens sheet group and negative lens sheet group, and every group of lens number is 2～3; The picture frame two ends are fixed with the rubber cover glass; Positive and negative lens are fixed in the picture frame by the plastics trim ring.
The utility model is compared prior art and is had following advantage:
1, eyeglass adopts positive and negative lens to combine, and its quality of optical imaging is better than the monolithic magnifier.
2, between the picture frame of the picture frame of positive lens sheet and negative lens sheet for being threaded, can rotate, the working substance that reaches the appropriate change magnifier is apart from the i.e. purpose of focusing.
3, there is headband at the picture frame two ends, can easily magnifier be worn on the head, hold without hand, and eyes can pass through clearly object observing of magnifier, and are easy to use, and eyes are had the certain protection effect.
4, simple in structure, be easy to processing, cost is low, and is practical, is easy to carry out using.
Accompanying drawing is a sectional structure chart of the present utility model.
Below with the utility model is described in further detail with reference to the accompanying drawings:
This utility model is made up of the positive lens (4) and the negative lens (7) of picture frame (3) and picture frame (9) and two eyeglasses, and its positive lens (4) is a positive lens groups, and negative lens (7) is a negative lens group.With rivet (1) rubber headband (2) is fixed on the two ends of picture frame (9), on picture frame (9), puts rubber cover glass (8).Positive lens groups (4) is contained in the picture frame (3), is fastened by plastics trim ring (5), and negative lens group (7) is contained in the Plastic mirror frame (9), is fastened by plastics trim ring (6).Plastic mirror frame (3) and Plastic mirror frame (9) are to adopt to be threaded, rotation Plastic mirror frame (3) just can be regulated the airspace between positive lens groups (4) and the negative lens group (7), make working substance apart from suitable change amount is arranged, just when using the magnifier object observing, rubber belt is worn on the head, can carry out an amount of focusing to magnifier by rotating Plastic mirror frame (3), hold magnifier without hand, two (or one) eyes just can make things convenient for, object observing clearly.
