Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cabinet device for electric equipment such as a television.

[0002]

[Prior Art]

 2. Description of the Related Art In recent years, many projection type television receivers have become widespread, and for example, there is a television receiver called a rear projection television.

As for the conventional rear surface shape of this television receiver, as shown in FIG. 1, the top of the back cover is fixed to the cabinet with screws, and thereafter the bottom of the back cover is fixed to the cabinet with screws.

[0004]

[Problems to be solved by the device]

 However, when trying to fix the back cover with such a conventional structure, an operator must hold and fix the back cover when determining the position. In addition, fixing the bottom of the back cover also requires pressing the bottom of the back cover by hand, which causes a problem of poor workability.

The present invention pays attention to the above problems, and provides a structure with good assembling workability in a television receiver.

[0006]

[Means for Solving the Problems]

 The mounting structure of the present invention facilitates fixing and positioning on the back cover by mounting a square bar or a similar structure on the cabinet, and after fixing it on the back cover with screws, The bottom of the back cover is hooked on the hook-shaped protrusions provided at the bottom, which makes it easy to position and fix the bottom of the back cover.

[0007]

[Action]

 According to the above configuration of the present invention, when fixing the back cover, the worker can fix the back cover on the crosspiece of the cabinet without holding it while holding the back cover. Also, since the bottom of the back cover is also hooked to the L-shaped projection on the back cover, the screw hole position can be fixed without the operator having to look for it.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

As shown in the figure, reference numeral 1 denotes a cabinet, which serves as a base for fixing the upper part of the back cover, the lower part of the back cover, the screen frame, etc., and for mounting a chassis and optical fittings containing a CRT. 2 is screwed to the cabinet on the back cover and covers the upper rear surface of the television receiver of the name Tori. Reference numeral 3 is under the back cover and is fixed to the cabinet with screws, and when this is removed, the main chassis can be seen. Reference numeral 4 denotes a back cover temporary fixing bar, which is provided at the center rear part of the cabinet, and by placing the back cover on this, an operator can perform work without holding the back cover. Reference numeral 5 is a hook-shaped projection for temporary fixing under the back cover, which is provided at two places in the lower portion of the back cover upper portion 2 in the figure. Reference numeral 6 denotes a hole for temporarily fixing the lower back cover, and by fitting the projection 5 for temporarily fixing the lower back cover, the screw fixing work for the lower portion 3 of the back cover is facilitated.

When assembling the back cover to the projection type television receiver, first, the back cover top 2 is placed on the back cover top temporary fixing bar 4 while the cabinet 1 includes optical fittings and a chassis. And fix it with a screw. Next, the back cover lower part 3 can be temporarily fixed by hooking the back cover lower part temporary fixing hole 6 of the back cover lower part 3 to the back cover lower part temporary fixing protrusion 5 of the back cover upper part 2 to fit them. After this, the worker tightens the screw to completely fix it.

The cross-sectional view of FIG. 2 shows a state in which the back cover top 2 is placed on the back cover top fixing rail 4 attached to the cabinet 1.

3 and 4 both show that the back cover lower temporary fixing protrusion 5 of the back cover 2 is fitted with the back cover lower temporary fixing hole 6 of the back cover lower 3. It shows an example of the lower temporary fixing projection 5.

[0013]

[Effect of the device]

 As is apparent from the above embodiments, the workability of assembling is improved by modifying the upper and lower back covers and the cabinet of the present invention.
