Liquid cooling type projection cathode ray tube

A projection cathode ray tube, comprising:

• a funnel-shaped body having an electron gun in a neck end and a face plate provided with a screen at a projection end;
• a rectangular radiating plate having a frontal glass element corresponding to said face plate having said screen located inside thereof, firmly attached to said face plate;
• a liquid coolant layer, having a predetermined thickness and located between said face plate and said frontal glass of said radiating plate;
• and
• clamping means coupled by a bolt and a spring provided thereon at each corner of said rectangular radiating plate for clamping the radiating plate to the projection end of the body, and a setting clasp supported to each bolt, having a contacting surface of a predetermined size in contact with the side of said funnel, whereby said setting clasp engages said funnel while pressing thereto,
• wherein each said bolt of said clamping supports a corresponding elastic reinforcing member of sheet iron bent into a V-shape to act on a corresponding setting clasp so that the corresponding setting clasp is elastically acted upon at one side by said spring and on an opposite side by said V-shaped reinforcing member.
