Background technique
At present; adopt charging air inlet to be connected with one-way valve on the optical instrument with the nitrogen source of the gas respectively during the maintenance of large-scale optical instrument such as periscope mostly with buffering filter; the paddle dryer of nitrogen in buffering filter; filtration and decompression are after the one-way valve on the optical instrument is filled to the positions such as eyeglass of optical instrument; to reach mildew-resistant to optical instrument; moistureproof; anticorrosion; protective actions such as insect protected; the structural representation of this charging air inlet as shown in Figure 1; be one to have the straight tube that expands end of female thread wherein with the connecting end of optical instrument one-way valve; the straight tube end connects the buffering filter 3 that is filled with filtering material 2, and the other end of buffering filter 3 is connected with source of the gas.Prove that through long-term practice the charging air inlet of said structure and this maintain measure can make optical instrument be in good stand-by state all the time, reduce unnecessary maintenance, prolonged the working life of optical instrument greatly.But for some as middle-size and small-size optical instruments such as distance meter, telescopes, because its model is many, kind is assorted, not of uniform size, be difficult to realize that with the charging air inlet of said structure optical instrument to various models and kind is connected inflation and carries out care and maintenance, thereby when reality is maintained, have to adopt leather hose to dock and inflate with the optical instrument one-way valve, thereby cause and waste time and energy, the maintenance weak effect, waste nitrogen.
Goal of the invention
For a change middle-size and small-size optical instrument condition of storage and maintenance environment, the utility model provide a kind of simple in structure, be easy to install the optical instrument charging air inlet of exchange, to solve the deficiencies in the prior art.
Summary of the invention
The purpose of this utility model is achieved in that this charging air inlet that is used to maintain optical instrument, and it is the tubular construction that is provided with a through hole, an end that it is characterized in that charging air inlet is radially bulging and extending axially respectively, radially the bulging end forms a boss with the connecting part that extends axially end, extends axially end and forms and the adaptive interface of optical instrument one-way valve.
Above-mentioned interface is provided with external screw thread, and interface length is 10～15mm.
The technological progress that the utility model is obtained:
1. because structure of the present utility model, solved the situation that to fill the nitrogen maintenance to the large-scale optical instrument of part, make the middle-size and small-size optical instruments such as distance meter, telescope of various models, kind and size all can maintain to reach effects such as mildew-resistant, protection against the tide, anticorrosion, insect protected by the utility model butt joint inflation, reduce unnecessary maintenance, effectively prolonged the working life of optical instrument.
2. owing to adopt the utility model to maintain, improved working efficiency greatly, docked the inflation maintenance with the leather hose of wasting time and energy in the past relatively, optical instrument of dry maintenance can improve work efficiency 80%, also can save nitrogen 50% simultaneously.
3. the utility model overall structure is simple, and be convenient to exchange to be installed and use with the optical instrument of various models, kind and size, low production cost, easy to install, thereby have good value for applications.
