Abstract
The utility model discloses a length adjusting device in an aperture device, which comprises a bolt and a socket which are connected between a rod-shaped aperture part and a spiral adjusting device as well as a locking part which is used for locking the relative position between the bolt and the socket. The length adjusting device of the aperture device can realize adjustment according to the preset length when installing the aperture device, and lead the installed aperture device to fit for the adjustment of aperture holes.
Description
Technical field
The utility model relates to a kind of adjusting gear, relates in particular to a kind of length adjuster that is used to adjust the aperture device entire length.
Background technology
Diaphragm is meant edge, framework or the special barrier with holes that is provided with of optical element in the optical system spare.Diaphragm is divided into two kinds by its effect: aperture diaphragm and field stop.Aperture diaphragm is meant the diaphragm that limits at most to the bore of object point light beam on the axle (solid angle or luminous cross section).So-called visual field is exactly the object plane scope of energy imaging, and field stop is meant the maximum diaphragm of visual field restriction to the optical system imaging.Diaphragm needs to carry out the position adjustment in observing testing process, the mode of general frequent employing spiral precession is adjusted location of aperture, specifically comprises rack and rinion adjustment and micromatic setting again.But the range of adjustment of above-mentioned spiral regulator is certain, if there is deviation in the parts that the length in the aperture device is bigger (for example diaphragm three hole seats) processing, cause the length dimension of whole aperture device to have deviation, at this moment above-mentioned spiral regulator just can not adjustment work in normal setting range, its certain adjustment range need be used for the above-mentioned parts that have machining deviation of polishing, and this will directly influence the operate as normal of various adjusting gears.
Summary of the invention
For this reason, technical problem to be solved in the utility model is the influence that is subjected to part component processing size easily of existing aperture device and causes the technical matters that spiral regulator can't operate as normal, proposes a kind of length adjuster that is specially adapted to aperture device.
For solving the problems of the technologies described above, length adjuster in a kind of aperture device of the present utility model, comprise: be connected latch and slot between diaphragm rod-like members and the spiral regulator, and the Lock Part that locks described latch and described slot relative position.
In the technique scheme, described latch is connected with described diaphragm rod-like members, and described slot is connected with described spiral regulator.
In the technique scheme, described latch is connected with described spiral regulator, and described slot is connected with described diaphragm rod-like members.
In the technique scheme, the screw of described Lock Part for locking by precession.
Technique scheme of the present utility model has the following advantages compared to existing technology:
The length adjuster of aperture device of the present utility model can be regulated according to pre-set length when aperture device is installed, and is suitable for the adjustment of aperture after it is installed.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment of the utility model also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is the length adjuster structural representation on the diaphragm device of the present utility model;
Fig. 2 is the enlarged diagram of X part among Fig. 1;
Reference numeral is expressed as among the figure: 1-diaphragm rod-like members; The 2-spiral regulator; The 31-latch; The 32-slot; The 33-Lock Part.
Embodiment
Fig. 1 and Fig. 2 have shown a kind of embodiment of the utility model, length adjuster in a kind of aperture device, comprise: be connected latch 31 and slot 32 between diaphragm rod-like members 1 and the spiral regulator 2, and the Lock Part 33 that locks described latch 31 and described slot 32 relative positions.As shown in Figure 1, described latch 31 is connected with described diaphragm rod-like members 1, and described slot 32 is connected with described spiral regulator 2.The screw of described Lock Part 33 for locking by precession.Described latch 31 can insert in the described slot 32 1-4 centimetre.
The course of work of the length adjuster of aperture device of the present utility model is: entire length and preset length after assembling according to diaphragm compare, adjusting can be described the length inserted in the described slot 32 of latch 31 so that the entire length of aperture device is suitable for installing.Aperture device of the present utility model is regulated according to pre-set length when aperture device is installed, and is suitable for the adjustment of aperture after it is installed.
Certainly, in other embodiment, can also be that described latch 31 is connected with described spiral regulator 2, described slot 32 is connected with described diaphragm rod-like members 1.Can play equally and adjust the aperture device entire length to be fit to the goal of the invention of its installation.The length that described latch 31 can insert in the described slot 32 can be provided with flexibly according to the needs of aperture device, does not repeat them here.
Obviously, the foregoing description only is for example clearly is described, and is not the qualification to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being extended out thus or change still are among the protection domain of the invention.
Claims (4)
1. the length adjuster in the aperture device, it is characterized in that, comprise: be connected latch (31) and slot (32) between diaphragm rod-like members (1) and the spiral regulator (2), and the Lock Part (33) that locks described latch (31) and described slot (32) relative position.
2. length adjuster according to claim 1 is characterized in that, described latch (31) is connected with described diaphragm rod-like members (1), and described slot (32) is connected with described spiral regulator (2).
