Description

Anti-vibration combined device of CRT and front mask

The present invention relates to the anti-vibration combined device of the CRT and the front mask to tightly couple the CRT to the front mask during the assembly process of the TV and to prevent vibration from being transmitted to the CRT through the front mask. , The first screw of the double screw of different upper and lower diameters is coupled to the first screw groove formed in the fixing lug of the CRT, and the first and second screws of the double screw are made of the support member positioned below the fixing lug. 1 and 2, the second screw portion of the double screw is inserted into the seating groove and fixedly coupled to the second screw groove of the high information screw installed at each corner of the inner surface of the front mask, and the double screw between the support member and the high information screw. An elastic ring made of elastic rubber is fitted to fix the vibration of the second threaded portion of the screw.

Accordingly, the coupling between the CRT and the front mask is more firmly maintained due to the double coupling structure, and the vibration of the front mask is prevented from being transmitted to the CRT by the elastic ring that is coupled between the high elasticity and the fixing lug. The present invention relates to a combined anti-vibration device for a CRT and a front mask, which prevents screen shaking, and prevents screen defects such as screen bending when the TV is applied, thereby improving product reliability of the TV.

In a conventionally known combination of a television CRT and a front mask, as shown in FIGS. 1 and 2, fixing grooves 104 are formed at each corner of the fixing iron strip 102 coupled to the planar portion of the CRT 100. Fixed lugs 106 are installed, respectively, and the high grooves 112 installed at each corner portion of the inner surface of the front mask 110 coupled with the CRT 100 are fixed grooves of the fixed lugs 106. The fixing screw 120 through the 104 is screwed to form a structure in which the CRT 100 is coupled to the inside of the front mask 110.

Therefore, in the combination structure of the CRT and the front mask of the conventional TV having the above structure, as shown in Figs. 1 and 2, the CRT 100 of the CRT 112 of the front mask 110 is After matching the fixing lugs 106 installed at each corner of the fixing iron band 102, the fixing screw 120 is coupled to the high information 112 through the fixing washer 122.

However, in the coupling structure of the CRT and the front mask of the conventional TV as described above, as shown in Figs. 1 and 2, when the TV CRT 100 and the front mask 110 are coupled, the front mask 110 is used. Since there is no separate vibration absorbing structure between the CRT and the CRT 100, the vibration generated from the speaker (not shown) installed in the CTV is transmitted to the CRT 100 through the front mask 110 as it is, and thus the assembled TV is completed. In use, a screen quantity condition such as a screen shake such that the screen of the CRT 100 is bent due to the vibration of the front mask 110 is easily generated, which causes a problem that the product reliability of the TV is degraded.

In addition, when the combined state of the front mask 110 and the cathode ray tube 100 is used for a long period of time due to the unitary structure in which the fixing screw 120 of the single structure is coupled to the high information 112 through the fixing washer 122. Or there are a number of problems, such as the possibility of loosening when the heavy flow occurs, the coupling state is weak.

The present invention has been devised to improve the above-described conventional problems, and its purpose is to maintain the coupling between the CRT and the front mask more firmly due to the structure of double coupling, and the elasticity that is coupled between the high elasticity and the fixing lug. Since the vibration of the front mask is prevented from being transmitted to the CRT by the ring, screen shaking of the CRT is prevented, and thus, a screen failure phenomenon such as the screen being bent when the TV is applied is prevented, thereby improving the product reliability of the TV. On the other hand, it is to provide an anti-vibration combined device of the CRT and the front mask which extends the life of the television.
