Abstract
The invention relates to the field of electronic measuring instruments, in particular to a high-precision resetting and quick-replacing device of an optical power meter joint. The joint-replaceable device of an optical power meter comprises a substrate (4) and a replaced joint (2) and is characterized in that a boss (4a) is arranged at one end of the substrate (4), and an annular groove (7) is arranged at the end part of the boss (4a). An annular boss (5) is arranged at the bottom of the replaced joint (2) and is matched with the annular groove (7) in a high-precision mode. A thread is arranged at the cylindrical surface of the boss (4a), and the boss (4a) is matched with a lock nut (1) through the thread, so that the substrate (4) is fixedly connected with the replaced joint (2). The joint-replaceable device of the optical power meter has the beneficial effects that the joint is more conveniently replaced, the positioning of different types of replaced joints is precise, and the precision of repeated measurement is ensured.
Description
Technical field
The present invention relates to the electronic measuring instrument field, particularly relate to a kind of high precision resetting, quick replacement device of light power meter joint.
Background technology
Light power meter in actual use because test with the plug form of external optical fiber difference, makes the joint that matees on the light power meter also will change thereupon.Present light power meter is changed joint generally has two kinds of forms: the one, change whole joint, and advantage is to guarantee measuring accuracy, shortcoming is that cost is high, the replacing trouble; The one, keep the photoelectric tube pedestal; Only change top sub, top sub and pedestal are with being threaded, though solved the problem of changing trouble like this; But it is consistent with the photoelectric tube relative position to guarantee to change joint owing to be threaded, and makes the duplicate measurements precision of instrument reduce.
Summary of the invention
The objective of the invention is to solve and change the instrument duplicate measurements precision reduction that joint causes, and the problem of changing trouble.
The objective of the invention is to be achieved through following technical scheme:
The replaceable piecing devices of light power meter, but comprise pedestal and changing-over head, it is characterized in that pedestal is provided with boss, the boss end is provided with annular groove, but changing-over head bottom is provided with annular boss, and annular boss cooperates with the annular groove high precision; The boss periphery is provided with screw thread, boss and locknut threaded engagement, thereby but pedestal is connected with the changing-over head fixing, but to guarantee changing-over head and the photoelectric tube coaxial cooperation that is located at base interior.
On the basis of technique scheme, following further technical scheme can be arranged:
Said boss is provided with detent, but changing-over head bottom is provided with locating piece, and locating piece forms the location with detent and cooperates, but a pedestal and a changing-over installation site are retrained fully.
The replaceable piecing devices employing of said light power meter is prone to cut stainless steel and makes material, can under the situation that does not need coating, guarantee accuracy requirement, and is simultaneously antirust.
It is more quick that beneficial effect of the present invention is not only to change joint, and it is accurate to change dissimilar joint location, guaranteed the precision of duplicate measurements.
Following constipation closes accompanying drawing and embodiment further specifies the present invention:
Description of drawings:
Fig. 1 is a structure cut-open view of the present invention;
But Fig. 2 is the synoptic diagram of a changing-over part;
Fig. 3 is the synoptic diagram of base part.
Embodiment
Like Fig. 1,2, shown in 3, piecing devices are connected the light power meter outside with the ring flange of pedestal 4, and pedestal 4 is provided with boss 4a, and boss 4a end is provided with annular groove 7, but changing-over 2 bottom are provided with annular boss 5, and annular boss 5 cooperates with annular groove 7 high precision; Boss 4a is provided with detent 8, but changing-over head (2) bottom is provided with locating piece 6, and locating piece 6 forms the location with detent 8 and cooperates; Boss 4a periphery is provided with screw thread, boss 4a and locknut 1 threaded engagement, thereby but pedestal 4 and changing-over 2 be connected fixing, but guaranteed photoelectric tube 3 coaxial cooperation that changing-over 2 is inner with being located at pedestal 1.
During installation, but the annular boss 5 of changing-over 2 bottom cooperates with the annular groove 7 high precision anchor rings of boss 4a; Locating piece 6 is inserted in the detent 8; Like this, even under locknut 1 uninstalled situation, annular boss 5 also cannot freely rotate in annular groove 7; But guaranteed the uniqueness of changing-over 2 and pedestal 4 installation sites, but promptly guaranteed the uniqueness of the relative position of photoelectric tube 3 and changing-over 2.But the changing-over of different size 2; Annular boss 5 sizes of its bottom are unified, because the characteristic of said apparatus, but can both guarantee the unitarity of the relative position of photoelectric tube 3 and changing-over 2; Behind the locking locknut 1, but realization makes the constraint fully of pedestal 4 and changing-over 2 installation site.But change different changing-overs 2 o'clock, unclamp locknut 1, get final product but change new changing-over 2.
Because after the part processing of the present invention, its coating size is difficult to control, has satisfied not the requirement of high precision fit dimension, part employing being prone to cut stainless steel of the present invention is made material and can under the situation that does not need coating, be solved antirust problem, and guarantees high-precision requirement.
Claims (2)
1. replaceable piecing devices of light power meter; Comprise pedestal (4) but and changing-over head (2); An end that it is characterized in that pedestal (4) is provided with boss (4a); Boss (4a) end is provided with annular groove (7), but changing-over head (2) bottom is provided with annular boss (5), and annular boss (5) cooperates with annular groove (7) high precision; Boss (4a) periphery is provided with screw thread, boss (4a) and locknut (1) threaded engagement, thus be connected fixing with pedestal (4) but with changing-over head (2).
2. the replaceable piecing devices of light power meter according to claim 1 is characterized in that boss (4a) is provided with detent (8), but changing-over head (2) bottom is provided with locating piece (6), and locating piece (6) forms the location with detent (8) and cooperates.
