Abstract
The utility model discloses a device for adjusting a tiny slit, comprising a connector having a square locating groove on the upper end surface and a through hole in the center. A left slit sheet and a right slit sheet each having a blade are arranged on two sides of the square locating groove, and both the slit sheets have one end facing each other and hanging at the position of the through hole respectively, so that the left slit sheet and the right slit sheet are blade-to-blade arranged and a minimal slit is formed therebetween. The left slit sheet and the right slit sheet each is respectively provided with a batten for compacting the left slit sheet and the right slit sheet into the square locating groove of the connector. A base is installed on the connector with the bottom abutting against the battens and is provided with bolts for fixing the base on the connector. The device has a reasonable structure, thin and flattened blades are employed for adjusting a space to obtain a required slit, and so adjustment is convenient, processing and manufacturing is simple and cost is low.
Description
Technical field
The utility model mainly is a kind of device of regulating small slit, is applicable to the space that slit separation is little, the installation site is little, especially is applicable to the nano level branch optical filtering of spectral bandwidth ripple.
Background technology
At present; Known small slit arrangement is the long rabbet that goes out the slit sheet with the line cutting processing, the long rabbet section out-of-flatness of slit sheet, and the narrow and small grinding and polishing of long rabbet width is not all right; The slit sheet also has certain thickness; Spectrum blur margin when projection divides the optical filtering ripple is clear like this, and shade is arranged, and the analysis of carrying out spectrum is very bad.
The utility model content
The utility model technical matters to be solved provides a kind of device of regulating small slit, and its reasonable in design adopts thin and smooth blade to come the adjusting play to reach the requirement of slit, and easy to adjust, the simple cost of processing and manufacturing is low.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of device of regulating small slit; It is characterized in that: include joint, have square locating slot on the upper surface of joint, the central authorities of said joint have through hole; Two ends are placed with the left slit sheet that has edge, right slit sheet respectively in the square locating slot of said joint; The end that two slit sheets are relative is suspended in lead to the hole site separately, and described left slit sheet and right slit sheet blade be to the relative placement of blade, and between the relative blade of left slit sheet and right slit sheet minim gap is arranged; Be respectively equipped with press strip on described left slit sheet and the right slit sheet, press strip is pressed on left slit sheet and right slit sheet in the square locating slot of joint; On the described joint base is installed, the bottom surface of base is against on the press strip, has bolt that base is fixed on the joint on the described base.
Minim gap between the relative blade of said left slit sheet and right slit sheet is nano level gap.
Described press strip adopts soft material to make.
The device of the small slit of adjusting of the utility model can be accomplished the nano level clearance slits of various requirement; The utility model can be made modularization and produce in batches.
Left slit sheet, right slit sheet are the double-edged razor blades of buying with the outside in the utility model, have thin and smooth blade, adopt line to be cut into needed profile and not destroy original edge.
The utility model has the advantages that:
The utility model reasonable in design adopts thin and smooth blade to come the adjusting play to reach the requirement of slit, and easy to adjust, the simple cost of processing and manufacturing is low.

Embodiment
Referring to Fig. 1; A kind of device of regulating small slit; Include joint 4, have square locating slot 8 on the upper surface of joint 4, the central authorities of said joint have through hole 9; Two ends are placed with the left slit sheet 2 that has edge, right slit sheet 3 respectively in the square locating slot 7 of said joint 4; Two slit sheets 2 and 3 relative ends are suspended in through hole 8 positions separately, described left slit sheet 2 and of the relative placement of right slit sheet 3 blades to blade, and between the relative blade of left slit sheet 2 and right slit sheet 3 minim gap 1 is arranged; Be respectively equipped with press strip 5 on described left slit sheet 2 and the right slit sheet 3, press strip 5 is pressed on left slit sheet 2 in the square locating slot of joint 4 with right slit sheet 3; On the described joint 4 base 7 is installed, the bottom surface of base 7 is against on the press strip 5, has bolt 6 that base 7 is fixed on the joint 4 on the described base 7.
Minim gap 1 between the relative blade of said left slit sheet 2 and right slit sheet 3 is nano level gap.
Described press strip 5 adopts soft material to make.
During making; Earlier two are had in the left slit sheet 2 of edge, the locating slot that is placed on joint 4 of right slit sheet 3 blades to blade; Adjust nano level gap 1 between left slit sheet, right slit sheet two blades within the specific limits, adjust, adjust the back and compress left slit sheet 2, right slit sheet 3 with soft material press strip 5 according to minute gap of optical filtering ripple needs; Take the end of from bolt 6 again base 7 is fixed on the joint 4, make the adjusting slit parts of an integral body.
Claims (3)
1. device of regulating small slit; It is characterized in that: include joint, have square locating slot on the upper surface of joint, the central authorities of said joint have through hole; Two ends are placed with the left slit sheet that has edge, right slit sheet respectively in the square locating slot of said joint; The end that two slit sheets are relative is suspended in lead to the hole site separately, and described left slit sheet and right slit sheet blade be to the relative placement of blade, and between the relative blade of left slit sheet and right slit sheet minim gap is arranged; Be respectively equipped with press strip on described left slit sheet and the right slit sheet, press strip is pressed on left slit sheet and right slit sheet in the square locating slot of joint; On the described joint base is installed, the bottom surface of base is against on the press strip, has bolt that base is fixed on the joint on the described base.
