SEALING DEVICE FOR MANUFACTURING CATHODEERAY TUBE

摘要

PURPOSE:To obtain a device which can be adjusted with ease and in a short time by mounting a frame stand which positions a cathode-ray tube based on the panel side of the cathode-ray tube so that the frame stand can be revoloved against a base holder. CONSTITUTION:Pads 11 which secure a cathode-ray tube 1 and a lever 15 are mounted inside a C-shaped frame stand 10 and a C-shaped angle adjusting plate 14 is secured in a body on this lower inside. A long groove 14a A number of long grooves 14 are formed at an equal distance from a center on the plane section of the angle adjusting plate 14 and fit in a C-shaped base holder 16 which is secured to a sealing device so as to revolve. Subsequently, screws 18 are inserted in the long groove 14a and screwed to the screw section 16b of the holder 16, and then the angle adjusting screw 14 is secured. A rise section 16a is provided on both ends of the holder 16. Angle adjusting screws 17 are screwed and each tip makes contact to the end of the adjusting plat 14. This can easily adjust the insetion angle of the electron gun 2 of different tubes with the use of the angle adjusting screw 17 by loosening the screws 18.
