Abstract
The utility model discloses a glasses box with a telescopic function. The glasses box consists of a box body (1), a convex lens (2), a concave lens (3) and a focal length regulating device (4). The glasses box with the telescopic function is characterized in that the convex lens (2) is arranged on the left side end surface of the glasses box body (1); the concave lens (3) is arranged in the middle of the focal length regulating device (4) and the concave lens (3) and the focal length regulating device (4) are arranged at the right side end surface of the box body (1). Vertical surfaces of the two sides of the glasses box disclosed by the utility model are respectively equipped with a convex lens magnifying lens and a concave lens reducing lens, and the focal length regulating device is further arranged, so that the glasses box has a monocular-observation telescopic function for distant scenes, and has the characteristics of being novel in conception, dual-purpose, and convenient to use.
Description
Technical field
The utility model relates to Special glasses box and makes applied technical field, refers to especially a kind of spectacle case with function of telescope.
Background technology
Spectacle case is only to use as holding glasses under regular situation, function singleness, in some cases, people's out on tours, missing or while looking around at a distance landscape, need to use the function of looking in the distance, but common spectacles or reading glasses cannot be realized and look at a distance thing and amplify shortening effect, if the mirror case of the preservation glasses of carrying can be used and makes it have function of telescope, the good things that one action two obtains beyond doubt.
Summary of the invention
The utility model provides a kind of spectacle case with function of telescope, and this mirror case has been installed respectively convex lens enlarging lens and recessed contract lenses on the vertical plane of both sides, adds focal length adjustment device, makes it possess the monocular vision function of telescope to distant place scene.
The technical solution of the utility model is achieved in the following ways: a kind of spectacle case with function of telescope, formed by box body, convex lens sheet, concavees lens and focal length adjustment device, it is characterized in that: convex lens are arranged on the left end face of mirror case box body, the centre that concavees lens are arranged on focal length adjustment device is arranged on its right end face of box body together with focal length adjustment device.
Described convex lens adopt transparent optical plastics or resin lens and glass lens to make, optic diameter 20-50mm, and footpath rate 2-10 is doubly.
Described concavees lens diameter 10-20mm, negative multiplying power 1-4 doubly.
Described focal length adjustment device is identical with telescope adjustment apparatus structure, is divided into internal and external screw sleeve C, b bis-parts, and external spiral sleeve b is fixed on box surface, in the middle of inside spin sleeve C, inlays concavees lens, and adjusting knob a is established in rear end.
The utility model, this mirror case has been installed respectively convex lens enlarging lens and recessed contract lenses on the vertical plane of both sides, adds focal length adjustment device, make it possess the monocular vision function of telescope to distant place scene, have novel, a thing dual-purpose, feature easy to use.
Brief description of the drawings
Fig. 1 is surface structure schematic diagram of the present utility model.

Fig. 3 is using method schematic diagram of the present utility model.
1 box body, 2 convex lens, 3 concavees lens, 4 focal length adjustment devices in figure.
Detailed description of the invention
From Fig. 1, know, a kind of spectacle case with function of telescope of the utility model, formed by box body 1, convex lens 2, concavees lens 3, focal length adjustment device 4, convex lens 2 are arranged on the left end face of mirror case box body 1, and the centre that concavees lens 3 are arranged on focal length adjustment device is arranged on its right end face of box body 1 together with focal length adjustment device.Described convex lens 2 adopt transparent optical plastics or resin lens and glass lens to make, optic diameter 20-50mm, and footpath rate 2-10 is doubly.Described concavees lens 3 diameter 10-20mm, negative multiplying power 1-4 doubly.Described focal length adjustment device 4 is identical with telescope adjustment apparatus structure, is divided into internal and external screw sleeve C, b bis-parts, and external spiral sleeve b is fixed on box surface, in the middle of inside spin sleeve C, inlays concavees lens, and adjusting knob a is established in rear end.
It is produced assembly technology flow process and is described below: 1. concavees lens 3 are assembled in focal length adjustment device 4 and pack in the reserved fixing hole of box body 1 right flank and fixed with screw; 2. convex lens 2 are packed in the reserved circular hole of the interior left end face of box body 1, fix at the screw diagonal angle, edge of convex lens 2 with fixed trap, be assembled into a spectacle case with function of telescope.
In conjunction with Fig. 2 Fig. 3, using method of the present utility model is described as follows: the mirror case function that the utility model holds glasses is identical with common spectacles box, need to hold glasses time, lid is opened after glasses are put into and is detained lid; In the time going out to use function of telescope, take out glasses and put on (spectacles), buckle lid, the right hand is held box body 1 right eye is pressed close to in concavees lens 3 one end, the adjusting knob a of left hand rotation focal length adjustment device 4 rear ends to look thing the most clear till; In the time that surface protruding, concave mirror 2,3 need to be cleaned, in mirror case, take out Glass cleaning cloth wiped clean.
