Description

The adjustment structure of optical instrument

Technical field

The utility model relates to a kind of adjustment structure of optical instrument, relates in particular to a kind ofly by guiding structurals such as linear slide rails, makes the sleeve with optical mirror slip can make adjustment the structure stable and optical instrument that accurate linearity relatively moves.

Background technology

Optical technology is a high-tech industry, be usually used in the observation of astronomical celestial body and small material, the development that is applied as modern science of optical instrument provides sizable power-assisted, and even correlative studys such as activity from the development microorganism of space industry, rely upon the cooperation of optical technology invariably, human by the breakthrough on optical technology, the ability of outfield is explored in related having possessed, thereby has finished the scientific achievement of many greatnesses.

The telescope of high multiple and microscope are the optical instrument that is widely known by the people most, and the expanding-contracting action of the sleeve by having optical mirror slip to be adjusting focal length, so that object is presented in the observer at the moment with the attitude that multiple amplifies, and then object are observed operation.For high multiple amplifies the demand of visual effect clearly that reaches, the relevant element on the optical instrument must have quite high precision, with the actions such as refraction, reflection and focusing that make light do to expect.

Existing United States Patent (USP) Focuser For Optical Instrument (patentnumber:6069754, date:May 30,2000) promptly discloses the adjustment structure that an optical instrument is arranged, and it includes two sleeves, a guide element and an adjustment part.Wherein jacket casing is located on the sleeve with optical mirror slip, and carry out the flexible start of slippage by guide element, to adjust the focal length between optical mirror slip, this adjustment part is arranged on this sleeve, can provide the user to make sleeve do rough moving significantly and meticulous trimming movement.

Only, the adjustment structure of existing optical instrument has following great disappearance when reality is used:

1, contacts with the face of part between this guide element and this sleeve and guide this sleeve expanding-contracting action, yet, elongated distance increase when sleeve with optical mirror slip, the concentrated acting force that is born on this sleeve side face is also followed increase, thereby produce bending moment improperly, the profile that causes the optical mirror slip sleeve produces buckling phenomenon, and then influences the optical focus effect of eyeglass.

2, this guide element is done a plurality of contacts on the side face of this optical mirror slip sleeve, and exercises relative slippage action simultaneously, after repeatedly using for a long time, produces tangible scratch on this sleeve side face, and it is attractive in appearance to have a strong impact on product.

3, this guide element can't provide the more accurate slippage of this sleeve action, and the user must can obtain its required optical focus effect via adjustment repeatedly.

Therefore, the above-mentioned disappearance of the utility model people thoughts can be improved, and is that the spy concentrates on studies and cooperates the application of scientific principle, proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned disappearance finally.
