Abstract
The utility model discloses a desk kinescope, mainly solving the technical problem of reducing the weigh of the bulb. The utility model adopts the technical proposal that: the desk kinescope is provided with a glass bulb made up by a TV panel and a glass envelope, wherein, the TV panel is a float glass paned, the connection point of the glass envelope and the TV panel extends. Compared with the prior art, the float glass panel is connected with the glass envelope, which reduces the weight of the kinescope and the manufacture cost of the glass bulb, on the basis that the vacuum performance of the desk kinescope is kept. The utility model is applicable to the monitoring device.
Description
Technical field
The utility model relates to a kind of picture tube, particularly a kind of small desk picture tube.
Background technology
Desk-top picture tube is applied to various occasions, known common picture tube glass bulb is to be made of glass screen and glass awl, glass screen and the low-melting glass welding of glass awl, the glass screen that adopts mold pressing to produce, with respect to the glass awl, the thickness of glass screen wants much thick, not only the weight of whole glass bulb is big, and cost is higher, has limited the extensive use of desk-top picture tube, particularly some special occasions.
Summary of the invention
The purpose of this utility model provides a kind of desk-top picture tube, and the technical problem that solve is the weight that alleviates glass bulb.
The utility model is by the following technical solutions: a kind of desk-top picture tube, a glass bulb that is made of glass screen and glass awl is arranged, and described glass screen is a float glass flat board, described glass awl and the junction prolongation of glass screen.
The thickness of float glass flat board of the present utility model is 4 millimeters.
Crt screen of the present utility model is of a size of 2.5 to 5.7 inches.
The utility model compared with prior art adopts dull and stereotyped the awl with glass of float glass to be connected, and has alleviated the weight of desk-top picture tube glass bulb, reduced the cost of glass bulb, and the vacuum performance of desk-top picture tube remains unchanged.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the glass bulb of desk-top picture tube of the present utility model is made of glass screen 1 and glass awl 2, glass screen 1 is the float glass flat board of 4 millimeters thick, for keeping the size constancy of glass bulb, glass awl 2 and the dull and stereotyped 1 junction extend outwards of float glass, to guarantee that electron beam focuses on the phosphor screen, desk-top crt screen size can be 2.5 to 5.7 inches.When making picture tube, glass awl 2 is gone up the low-melting glass bonding material along dripping on the awl mouthful limit, press fit in the frock with float glass flat board 1 again, put into sealing-in stove roasting sealing-in, through being coated with the screen evaporation of aluminum, reinstall electron gun afterwards, through seal, operation such as exhaust makes desk-top picture tube.
Claims (3)
1. a desk-top picture tube has one by the glass bulb that glass shields and the glass awl constitutes, and it is characterized in that: described glass screen is a float glass flat board, and described glass awl shields the junction with glass and prolongs.
2. desk-top picture tube according to claim 1 is characterized in that: the thickness of described float glass flat board is 4 millimeters.
3. desk-top picture tube according to claim 1 and 2 is characterized in that: described crt screen is of a size of 2.5 to 5.7 inches.
