Description

Mechanical adjustable optical attenuator
Technical field
This utility model relates to optical attenuator technical field, is specifically related to a kind of mechanical adjustable optical attenuator.
Background technology
Continuous progressive along with science and technology, communication technology is also rapidly progressed, and communication mode also changes followed by.Optical attenuator is a kind of important passive device for decaying luminous power, has important application in optic communication and light sensory field.It can be used for the occasions such as the signal attenuation of communication system, the index measurement of fibre system and system test.Generally there is the problem that structure is complicated, mechanical property requirements is higher in optical attenuator at present, and during regulation, adjusting screw rod does not has location structure, the most all exits, and makes troubles to use.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, it is provided that a kind of smart structural design, rationally, convenient regulation, and avoids the mechanical adjustable optical attenuator that screw rod exits completely.
For achieving the above object, technical scheme provided by the utility model is: a kind of mechanical adjustable optical attenuator, it includes main casing, nut and screw rod, the bottom of described main casing is transversely provided with the path channels extended transversely through, the top center of this main casing is vertically provided with the regulation screw being connected with described path channels, described screw rod is screwed into regulation screw, and described nut is arranged on the upper end of regulation screw, and can prevent screw rod from exiting completely from regulation screw.
A kind of improving as of the present utility model, the assembly cavity that the radially enlarged formation in top one of described regulation screw is suitable with described nut, the inwall of this assembly cavity is provided with spacing female thread, and the bottom of this regulation screw is provided with regulation female thread.
As a kind of improvement of the present utility model, the outer wall of described nut is provided with the spacing external screw thread suitable with spacing female thread, and the endoporus of this nut is shiny surface, and the upper surface of this nut is provided with nut regulation screens.
As a kind of improvement of the present utility model, the bottom of described screw rod is provided with conehead, middle part outer wall is provided with the regulation external screw thread suitable with described regulation female thread, and top radially reduces and forms a movable part that can pass from the endoporus of described nut, and the upper surface of this movable part is provided with screw rod regulation screens.
The beneficial effects of the utility model are: this utility model smart structural design, rationally, it is screwed into regulation screw by screw rod, and path channels can be stretched into, the frequency of light quantum can well be controlled, and nut of can screwing in nut regulation screw upper end, prevent the screw rod when regulation from exiting completely from regulation screw, easy to use, simple;Additionally overall structure is simple, compact, it is easy to accomplish, low cost, it is beneficial to be widely popularized utilization.
Below in conjunction with the accompanying drawings with embodiment, this utility model is further illustrated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of main casing in this utility model.
