Hereinafter, the present invention will be described in more detail based on the accompanying preferred embodiments as follows.

The component parts according to the present disclosure are broadly divided into a front case 10, a sub bracket 20 fixed to the front case, a substrate bracket 30 fixed to the sub bracket, and the substrate bracket. It consists of a bottom chassis 40 and a stand 50 having a stand base fixed to it.

Therefore, the front case 10 has a structure in which a cathode ray tube (not shown) is mounted and the rear case 70 is later assembled.

In addition, the sub bracket 20 is mounted on the lower portion of the rear side of the front case 10 so that the fixing pieces 22 on both sides are fixed to the front case 10 by the screw 21.

The sub bracket 20 has a catching hole 23 into which the catching piece 52 of the stand base 51 is inserted, and forms a fastening hole 25 at both sides of the rear piece 24 and forms a center thereof. Edo chassis fastening hole 26 is formed.

The coupling protrusions 27 are formed on both sides of the chassis fastening hole 26.

The substrate bracket 30 has a fixing piece 33 to be fixed to the sub bracket 20 by the screw 60 on both sides of the front portion, the fastening hole 32 in the middle of the front coupling piece 34 The coupling hole 35 is formed on both sides of the fastening hole 32 to insert the coupling protrusion 27 of the sub bracket 20.

In addition, two engaging holes 36 are formed on both sides of the bottom surface, respectively, on both sides in the front and rear directions, and a fastening hole 38 is interposed in the middle of the rear piece 37 and the fastening holes 38 are engaged on both sides. A jaw hole 39 is formed respectively.

The bottom chassis 40 has a fastening hole 42 to be fastened by a screw 48 in the middle of the front piece 41, and fastening holes 42 ′ for engaging with a stand at both sides of the fastening hole 42. It is provided with each.

And the bottom surface of the bottom chassis 40, both sides of the bottom bracket 40 is formed to protrude the engaging jaw 43 of the L-shape inserted into the locking hole 35 of the substrate bracket (30).

In addition, the fixing piece 45 is formed in the middle of the rear piece 44 of the bottom chassis 40, and the rear catching jaw 46 inserted into the locking jaw hole 39 on both sides of the fixing piece 45 is caught. The bottom portion is formed with a plurality of mating grooves 47 are inserted into the locking jaw portion 53 formed in the stand base 51 is formed. Here, reference numeral 49 denotes a coupling hole in which the coupling protrusion 27 is inserted through the coupling hole 35 of the substrate bracket 30.

The stand base 51 having the stand 50 is provided with a fixing piece portion 54 to be fastened by screws 60 on both sides of the front portion.

The assembly process thus constructed will be described with reference to FIG. 2.

In the present invention, the front case 10 and the cathode ray tube (not shown) are first coupled, and then the sub bracket 20 is fixed to the lower rear side of the front case 10. At this time, the fixing piece 22 is fixed by the screw 21 and is coupled to the front case 10 first.

Subsequently, the substrate bracket 30 is coupled, and the substrate bracket 30 is coupled to the substrate bracket 30 as a state of forming an assembly in which a main circuit board (not shown) is coupled to the substrate bracket 30.

In addition, the substrate bracket 30 may be an assembly component to which the bottom chassis 40 is coupled. Alternatively, the substrate bracket 30 may be assembled first, and then the bottom chassis 40 may be assembled thereto. have.

In the combination of the substrate bracket 30 and the bottom chassis 40, the locking jaw 43 of the bottom chassis 40 is inserted into the locking hole 36 of the substrate bracket 30, and then the bottom chassis 40 is inserted. When pushed in the direction of the front portion is the engaging jaw 43 is in the form of the L-shape is coupled to the engaging hole 36 and at the same time the rear engaging jaw 46 located in the rear end is inserted into the engaging jaw hole 39 Assembled in a jammed state.

As a result, the bottom jaw 43 and 46 of the bottom chassis 40 are in a state of being caught by the catching hole 36 and the catching jaw hole 39 of the substrate bracket 30. 40 is assembled in such a state that it will not be separated from the substrate bracket 30 unless it is moved to the rear direction and pulled out.

Here, the substrate bracket 30 in the assembled state as described above is assembled so that the front coupling piece 34 is in close contact with the rear piece 24 of the sub bracket 20, the coupling protrusion 27 ) Are inserted into the coupling holes 35 so that they can be mutually coupled in the correct position.

When assembled in the above state, the fastening holes (33) in the fastening holes (25) on both sides to achieve a state in which the fastening holes (26) (32) of the sub bracket (20) and the substrate bracket (30) are mutually matched. Is in a matching state.

Therefore, while the screw 48 is fastened to the fastening holes 26, 32 and 42 located in the middle portion, the fastening holes 26 and 38 and the fixing piece 45 positioned at the rear side are also screwed. The substrate bracket 30 and the bottom chassis 40 which form the assembly while being fastened by the 48 'are assembled to be attached to the sub bracket 20.

Next, after assembling the substrate bracket 30 to the sub bracket 20 will be described a process of binding the bottom chassis 40 to it.

In this case, the substrate bracket 30 is coupled to the sub bracket 20 as described above, and then fastened to the fixing pieces 33 and the fastening holes 25 on both sides using the screw 28. To fix them.

Next, the bottom chassis 40 is first fastened to be in close contact with the substrate bracket 30, and then the fastening holes 26, 32, 42 and the front and rear fastening holes using the screws 48, 48 ′ and The fastening holes 26, 38 and the fixing piece 45 is to be fixed to the secondary.

Next, the stand 50 is coupled to the bottom chassis 40. At this time, the locking piece 52 in the stand base 51 to the sub bracket 20, and the locking jaw 53 is matched to the matching groove 47 of the bottom chassis 40, and then pushed forward It is coupled in a locked state, and due to this coupling, the fixing piece portion 54 is in a state that matches the fastening hole 42 'of the bottom chassis 40.

Accordingly, when the screw 60 is fastened in the fixing piece portion 54 direction, the fastening holes 42 'and 32' of the fixing piece portion 54, the bottom chassis 40 and the substrate bracket 30 are fastened. Passed through is fastened to the fastening hole (25 ') of the sub bracket 20.

As a result, the stand 50 is bound by the bottom chassis 40 and the substrate bracket 30 with only the screw 60.

Therefore, when the rear case 70 is separated after the product is released during the after-service, the screw 60 is loosened for easy separation.

In detail, when the screw 60 is loosened and the stand base 50 is pulled in the rear direction to move, the catching piece 52 and the catching jaw 53 of the sub bracket 20 and the bottom chassis ( The stand 50 is separated from the locking hole 23 and the mating groove 47 of the 40.

Next, after unfastening the two screws 48, 48 'in the middle of the front and rear, the bottom chassis 40 is pulled and moved in the rear direction, and the catch hole 36 of the substrate bracket 30 As the locking jaw 43 and the 46 hanging on the locking jaw hole 39 are pulled out, the bottom chassis 40 can be easily removed.

Therefore, the exposure hole 31 drilled in the bottom of the substrate bracket 30 is exposed to the outside, through which the circuit configuration of the main circuit board can be checked or repaired.

Next, after repairing, the bottom chassis 40 is inserted into the locking hole 36 and the locking jaw hole 39 of the substrate bracket 30 as described above, and then the front portion is oriented. When pushed in, the bottom chassis 40 is assembled to the substrate bracket 30, and then the stand 50 is assembled, and then the screw 60 is fastened so as to be attached thereto.

Finally, the rear case 70 is completed to be assembled to the front case 10.

According to the above description, the assembly and disassembly of the stand and the bottom chassis are facilitated by this paper, so that the work can be easily performed and the fastening parts can be reduced by using only a few screws without using many screws. It is a useful design to make a product and increase the productivity.
