Abstract
The utility model provides a objective lens horizontally-pushing type objective rotation lens focusing device which is formed by a focusing hand wheel, a rubber leather sleeve, a compression ring, a housing, a seal ring, a stop screw and an objective lens group. The objective lens group is fixed by the pressing ring and a spacer ring, and a thread is arranged in the external surface of the objective group; the focusing handle wheel is connected with the housing via the thread; the compression ring is arranged in a connection gap; the rubber leather sleeve is wrapped around the focusing handle wheel; the objective group is connected with the inner surface of the housing via the thread arranged in the external surface of the objective group; and the stop screw is arranged on the tail end of the focusing handle wheel and is separately connected with the housing and the objective group. The objective lens horizontally-pushing type objective rotation lens focusing device is characterized by simple structure, good manufacturability, capability of being easy to seal, minimal effects on radial displacement of focusing optical axis, and good cooperation with an overall structure of a passive night vision binoculars and overcomes a disadvantage of a single function of an objective lens focusing device of a present passive night vision binoculars.
Description
Technical field
This novel a kind of horizontal sliding object lens formula rotation object lens focus control, genus optical focusing equipment technical field of relating to.
Background technology
The low-light binocular telescope is a kind of product for night observation, often need to regulate the focal length of object lens in the use procedure of this product, mainly be directly to rotate object lens and pass through focusing handwheel horizontal sliding object lens dual mode in the mode of regulating objective focal length at present, directly the rotation object lens are the most succinct directly modes, but this mode can cause the displacement that optical axis is radially larger owing to rotatablely moving of object lens in the process of regulating, thereby affect observation effect, and during by the focusing of focusing handwheel horizontal sliding object lens, object lens just move forward and backward under focusing handwheel promotes the choosing dress do not occur, although minimum on optical axis radial displacement impact, but because the factor of the integral structure layout of low-light telescope product, limited the setting of focusing handwheel, thereby caused great use inconvenience
Therefore need to a kind ofly can realize at present that the focusing of object lens flat push type can well adapt to again the integrally-built novel focus control of low-light binocular telescope.
Summary of the invention
This novel purpose just is to overcome above-mentioned deficiency, and a kind of horizontal sliding object lens formula rotation object lens focus control is provided.
For achieving the above object, originally novel is to be achieved through the following technical solutions:
A kind of horizontal sliding object lens formula rotation object lens focus control, described horizontal sliding object lens formula rotation object lens focus control is by focusing handwheel, rubber sleave, pressure ring, housing, O-ring seal, stop screw, objective lens consists of, described objective lens is by trim ring, spacer ring is fixed and the objective lens outside surface arranges screw thread, described focusing handwheel is connected with housing by screw thread and the joint gap place arranges pressure ring, rubber sleave is coated on the focusing handwheel, described objective lens arranges screw thread by outside surface and is connected with shell inner surface, and described stop screw is positioned at the focusing handwheel end and is connected with housing and objective lens respectively.
This new construction is simple, and good manufacturability, easily sealing, the radial displacement of focusing optical axis affect minimum and the characteristics good with low-light binocular telescope one-piece construction matching property, have overcome simultaneously the defective of the object lens focus control function singleness of present low-light binocular telescope.
