Abstract
The utility model relates to the sealing structure of an internal focusing optical instrument, comprising a lens barrel and a couple pin which can move back and forth in the egg-shaped slot of the lens barrel, and a sealed cowling which is made of deformable material and sheathed with the couple pin is arranged in the egg-shaped slot of the lens barrel. Since the sealed cowling of the sealing structure of an internal focusing optical instrument is fixedly sheathed with the couple pin for connecting with the lens barrel as one, the sealed cowling deforms and water proof function in focusing process is obtained via the sealed cowling being extruded by the couple pin.
Description
Technical field
The utility model relates to a kind of waterproof construction of interior focusing optical instrument.
Background technique
When in the seashore of humidity environment or navigation, using, usually select professional waterproof type optical instrument for use.Real waterproof type optical instrument structurally generally seals with filling clean dry nitrogen and employing O shape circle, and this structure is generally higher than complexity and component requirement on machining accuracy.
Summary of the invention
The purpose of this utility model is to provide a kind of sealing configuration of interior focusing optical instrument simple in structure.
For achieving the above object, the technical solution adopted in the utility model is: comprise the linkage pin that can move forward and backward in lens barrel and the avette groove on lens barrel, be characterized in having to be sleeved at the avette groove internal fixation of lens barrel and make seal closure by deformable material on the linkage pin.
Another characteristics of the present utility model are: seal closure is connected as a single entity by fixed block and lens barrel, and also is provided with the sealing compressing tablet between fixed block and seal closure; The upper end of linkage pin also is provided with a restraining groove, and seal closure is positioned at restraining groove.
Be one because seal closure of the present utility model is fixedly set on the linkage pin to be linked to be with lens barrel, by linkage pin crush seal cover, the seal closure distortion has reached the water-proof function in the focusing process.
Description of drawings
Accompanying drawing is an overall structure schematic representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to accompanying drawing, the utility model comprises the linkage pin 3 that can move forward and backward in lens barrel 1 and the avette groove 2 on lens barrel 1, fixed cover is equipped with the seal closure of being made by deformable material 4 on the linkage pin 3 in the avette groove 2 of lens barrel 1, this seal closure 4 can be connected as a single entity by fixed block 6 and lens barrel 1, also is provided with sealing compressing tablet 5 between fixed block 6 and seal closure 4.Fixed block 6 will seal compressing tablet 5 and compress, by sealing compressing tablet 5 crush seal covers 4, the extrusion-deformation of seal closure 4 filled up and lens barrel 1 matching part between the gap, when using optical instrument to observe, linkage pin 3 can before and after moving freely, in the focusing process, seal closure 4 moves to different positions with linkage pin 3 and produces corresponding deformation, remain lens barrel 1 inner chamber and be in sealing state, it is flexible to focus, and has realized the water-proof function of product at this position.
