The present invention forms a fixing device integrally with the frame on one side of the frame inserted into the upper back cover of the monitor, and the volume knob on the frame is formed by protruding the insertion protrusion at the center of the volume knob. One volume knob lock for simple fixed installation.

Conventionally, a large number of bosses are formed in a proper portion inside the rear cover to fix the volume knob to the monitor and are fixed by screw or the like as a screw, or a separate bracket is fixed on the frame as a screw. Due to the complexity, the manufacturing process of the required parts and its assembly work process are cumbersome, and the workability is lowered, resulting in an increase in selling price, and the conventional fixing method described above is fixed only on one side of the volume knob. There have been many problems, such as the difficulty of preventing the eccentricity of the volume knob due to the use of.

The present invention solves such a conventional problem and forms a pair of fixing pieces and an auxiliary support piece on one side lower end of the frame inserted into the rear cover, and the insertion protrusion is inserted into the fixing piece at the central portion of the volume knob. The volume knob is firmly fixed on the frame at the time of joining, and the circuit board integrally connected with the volume knob by the connecting piece is fixed on both sides of the volume knob by being fixedly supported by the auxiliary support piece. The purpose is to describe the configuration according to the accompanying drawings as follows.

Fixing protrusions 3 'having a plurality of annular projections having different outer diameters sequentially formed on the outer center portion of a conventional volume knob 3, which is connected to one side of the circuit board 1 by maintaining a proper spacing therebetween. Are respectively formed in the space portion formed on the side of the frame 8, and the fixing portion 7 made of the U-shaped guide is formed, but inside the lower portion of the U-shaped guide, the fixing protrusion at the time of coupling the volume knob 3 ( 3 ') is formed so that a plurality of annular projections having different inner diameters in order to be inserted and matched to form a fixed projection insertion hole (4), and a semi-circular contact piece (appropriate size) on the outer peripheral surface of one end of the fixing projection insertion hole (4) 5) so that the volume knob (3) is in contact with the contact surface (3 ") on the side of the knob to support the contact, and the upper side of the insertion hole (4) is connected to the outer periphery and the guide surface (6) inclined in the vertical direction Formed between the magnetic guides when the volume knob is combined Guide the fixing protrusion (3 ') so that it is simply inserted into the fixing protrusion insertion opening (4), the position where the volume knob (3) on both sides of the fixing plate (9) fixing fixture (7) attached to the U-shaped guide end side The auxiliary support pieces 11, 11 ′, 11 ″, on which the circuit board 1 can be fitted, are formed at the ends of the bottom plate 10 formed integrally with each other and extending at right angles to the fixing plate 9. In each case, the circuit board 1 is supported at the time of joining, and a rectangular knob insertion hole 12 is drilled in the bottom plate 10 directly below the contact piece 5, so that a part of the knob is engaged when the volume knob 3 is engaged. Reference numeral 13 denotes an auxiliary contact piece for supporting the contact surface 3 "on the side of the volume knob as the volume knob fixing device of the monitor configured to protrude out of the bottom plate 10.

Referring to the operation and effect of the subject innovation in this configuration as follows.

The distance between the fixing protrusions 3 'protruding to the center portions of the two volume knobs 3 at an appropriate size, respectively, is fixed to the both sides of the fixing plate 9 at the lower end of the frame 8, respectively. The auxiliary support piece 11 (11 ') having a distance between the fixing protrusion insertion openings (4) bored on the lower side and the circuit board (1) at the end of the base plate (10) on one side of the volume knob (3) ( 11 ") is installed so that the straight distance is maintained by the connecting piece 2 so as to be matched to the inner side of the 11 "), so that the volume knob 3 and the connecting piece are formed on both side fixing parts 7 formed integrally on the fixing plate 9. When the circuit board (1) connected by (2) is inserted into the fixing projection (3 ') is guided to the fixing projection insertion hole (4) along the guide surface (6) formed by maintaining the inclination angle on the fixing portion (7) In the fixed part (7) attached to only the end of the U-shaped guide end by the fixing protrusion (3 ') is pushed back because the upper side is medallion state And the fixing projection (3 ') is inserted into the insertion hole (4) and at the same time pushed back the fixed portion 7 is returned to its original state by elasticity, so that the volume knob (3) is coupled to the fixing projection insertion hole (4), the volume knob ( 3) The part is exposed to the outside of the insertion hole 12, wherein the circuit board 2 is inserted into the auxiliary support pieces 11, 11 ', 11 "installed at the end of the bottom plate 10, and is firmly supported. The volume knob 3 is firmly supported and fixed at both sides.

The present invention as described above eliminates the inconvenience caused in the conventional parts manufacturing process or assembling work, the assembling work on the frame is also easily assembled by hand and the volume knob (3) is fixed and supported at the same time on both sides It is a beneficial design to eliminate the eccentric phenomenon.
