Изобретение относитс  к области оптического приборостроени , в частности к устройствам дл  креплени  защитного оптического колпЯКа.The invention relates to the field of optical instrumentation, in particular, to devices for fastening a protective optical cap.

Известны устройства дл  креплени  защитного оптического колпака, содержащие оправу с канавкой, эластичную прокладку и резьбовое кольцо дл  регулировки усили  зажима. Однако такие устройства не обеспечивают герметизацию соединени  колпака больше полусферы при изменении давлени  и температуры .Devices for attaching a protective optical cap are known, comprising a frame with a groove, an elastic gasket and a threaded ring for adjusting the clamping force. However, such devices do not seal the cap joint more than a hemisphere when pressure and temperature change.

Цель изобретени  - обеспечение герметичного креплени  колпака, имеющего размер больше полусферы,, При изменении давлени  и температуры. Это достигаетс  тем, что на оправе выполнена сферическа  проточка, внутри которой установлены полукольца, а прижим выполнен в виде цанги, причем ловерхности проточки, полуколец и цанги выполнены взаимно сопр женными.The purpose of the invention is to provide a tight attachment of a cap having a size larger than a hemisphere, as the pressure and temperature change. This is achieved by the fact that a spherical groove is made on the frame, inside which half rings are installed, and the clamp is made in the form of a collet, and the grooves of the groove, semicircles and the collet are mutually conjugate.

На чертеже показано описываемое устройство .The drawing shows the described device.

Устройство содержит оправу 1 с канавкой 2. Опра;ва выполнена с расточкой ио сфере, радиус которой равен радиусу наружной сферы колпака 3. Канавка заполнена эластичной прокладкой 4. Дл  регулировки усили  зажима установлено резьбовое кольцо 5. В сферической проточке оправки установлены ПОлукольца 6 и 7, наружные поверхности которых сопр жены с внутренней поверхностью колпака , а прижим выполнен в виде цанги 8, -коническа  поверхность которой сопр жена с внутренней новерхностью полуколец 6 и 7.The device contains a frame 1 with a groove 2. The opra; va is made with a boring sphere, the radius of which is equal to the radius of the outer sphere of the cap 3. The groove is filled with an elastic gasket 4. A threaded ring 5 is installed to adjust the clamping force of the mandrel. , the outer surfaces of which are matched with the inner surface of the cap, and the clamp is made in the form of a collet 8, the conical surface of which is associated with the inner surface of the half-rings 6 and 7.

Устройство работает следующим образом.The device works as follows.

В нормальных услови х колнак 3, установленный в оправу 1, прижимаетс  к ее сферической поверхности усилием, создаваемым на прижиме 8 з-ат жкой резьбового кольца 5. Это усилие передаетс  через полукольца 6 и 7 и колпак 3. Герметизаци  соединени  осуществл етс  установкой в канавку 2 нрокладки 4. Давление снаружи воспринимаетс  через колпак 3 всей площадью сферической проточки оправы 1. Давление через колпак передаетс  на полукольца 6 и 7 и далее на цанговый зажим 8, его деформаци  приводит к увеличению усили  зажима в соединении.Under normal conditions, the collar 3, mounted in the frame 1, is pressed against its spherical surface by the force generated on the clamp 8 by the tapping of the threaded ring 5. This force is transmitted through semirings 6 and 7 and the cap 3. Sealing of the joint is carried out by installation into the groove 2 laying 4. The pressure from outside is perceived through the cap 3 with the entire area of the spherical groove of the frame 1. The pressure through the cap is transmitted to the half rings 6 and 7 and then to the collet clamp 8, its deformation leads to an increase in the clamping force in the joint.

Предмет изобретени Subject invention

Устройство дл  креплени  защитного оптического колпака, содержащее оправу с канавкой , эластичную прокладку и резьбовое кольцо дл  регулировки усили  зажима, отличающеес  тем, что, с целью обеспечени  герметичного кренлени  колпака, имеющего размер больше, полусферы, при изменении давлени  и температуры, на оправе выполнена сферическа  проточка, внутри которой установлены полукольца, а прижим выполнен в виде цанги, лричем поверхности проточки, полуколец и цанги выполнены взаимио сопр женными .A device for attaching a protective optical cap comprising a frame with a groove, an elastic gasket, and a threaded ring for adjusting the clamping force, characterized in that, in order to provide a sealed heel of the cap having a larger hemisphere, the pressure and temperature are spherical the groove, inside of which the half-rings are installed, and the clamp is made in the form of a collet, the surface of the groove, half-rings and collets are made mutually matched.
