Abstract

PURPOSE:To improve the mounting operability by providing a motion control rib projectingly toward a fitting side at the CRT mounting part of the cabinet and forming an engagement piece engaged with the motion control rib at the fitting. CONSTITUTION:When the CRT 1 is attached to the cabinet 2, the engagement pieces 6d of the respective fittings 6 are engaged with the motion control rib part 2b4 of the cabinet 2 respectively. Thus, positioning for making the axial centers of the inserting hole 6c of the fitting and the fastening boss part 2b3 of the cabinet 2 coincide can be naturally performed. Then, a fastening bolt 8 is fastened to the boss part 2b3 to be fixed after the bolt 8 is inserted to the inserting hole 6c of the fitting 6. In this case, since the motion of the fitting 6 is controlled by the motion control rib part 2b4 even when there is some play in the inserting hole 6c, the position of the CRT 1 to the cabinet 2 is not shifted even when screw torque is added.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a CRT on a cabinet.

[0002]

2. Description of the Related Art Conventionally, as a structure for mounting a CRT on a cabinet, there is a structure which adopts the structure shown in FIGS.

In these drawings, 1 is a CRT, 2 is a cabinet, 4 is a metal explosion-proof band, and 6 is a mounting bracket.

The explosion-proof band 4 is fastened over the outer circumference of the CRT 1. In addition, the mounting bracket 6 is the fixed portion 6
The a and the projecting portion 6b provided upright from the fixed portion 6a are substantially L-shaped, and an insertion hole 6c for the tightening bolt 8 is formed at the center of the projecting portion 6b. And the mounting bracket 6 is CR
At each of the four corners of T1, the fixing portion 6a is fixed on the explosion-proof band 4 by welding or the like. On the other hand, the cabinet 2 has a rectangular frame-shaped frame portion 2a, and CRT mounting portions 2b are integrally formed with the frame portion 2a at each of the four corners of the frame portion 2a. This C
RT mounting portion 2b is flat with mounting base 2b _1, a reinforcing rib portion 2b ₂ erected toward the outer edge of the mounting base 2b ₁ to the mounting bracket 6 side, mounted from the mounting base portion 2b ₁ fitting 6 Fastening boss 2b ₃ for screwing the fastening bolt 8 projecting toward the side
Consists of.

To attach the CRT 1 to the cabinet 2, the fastening bolts 8 are inserted into the insertion holes 6c of the respective mounting brackets 6.
And the fastening bolt 8 is fixed by screwing the fastening bolt 8 into the fastening boss portion 2b ₃ of the mounting portion 2b of the cabinet 2.

[0006]

By the way, when the CRT 1 is attached to the cabinet 2, the inner diameter of the insertion hole 6c is such that the tightening bolt 8 can be easily inserted into the mounting bracket 6. The diameter is set to be slightly larger than the diameter, so that the insertion hole 6c has a so-called play allowance with respect to the tightening bolt 8. Therefore, when the CRT 1 is attached to the cabinet 2 using the tightening bolts 8, the CRT 1 may be attached due to the tightening torque and the weight of the CRT 1.
Caused a positional deviation with respect to the cabinet 2, and as a result, a problem such as the CRT 1 being obliquely fixed to the cabinet 2 occurred. The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to always fix a CRT to an appropriate position with respect to a cabinet.

[0007]

Therefore, according to the present invention,
At least two of the four corners of the CRT are fixed with fittings having insertion holes for fastening bolts, and at least two of the four corners of the rectangular frame-shaped cabinet into which the CRT is fitted. Is formed with a CRT mounting portion in which a fastening boss portion is provided so as to project toward the mounting metal fitting side, and to the CRT cabinet in which the fastening bolt inserted through the insertion hole is screwed into the fastening boss portion. The following structure is adopted in the mounting structure of.

That is, according to the present invention, a flat plate-shaped movement regulating rib is provided on the CRT mounting portion of the cabinet so as to project toward the mounting metal fitting side, while the mounting metal fitting is engaged with the movement regulating rib. The feature is that an engaging piece is formed.

[0009]

In the above structure, when the CRT is mounted on the cabinet, the engaging pieces of the respective fittings are engaged with the movement restricting ribs of the cabinet. As a result, the insertion hole of the mounting member and the fastening boss portion of the cabinet are naturally aligned with each other, so that the labor for aligning them can be saved. Then, after inserting the tightening bolt into the insertion hole of the mounting bracket, tighten the fixing bolt to the fastening boss to fix it.In this case, even if there is a play allowance in the insertion hole, the mounting bracket moves Is regulated by the movement regulation rib portion, so that the CRT will not be displaced with respect to the cabinet even if a tightening torque or the like is applied. Therefore, the CRT is always attached to the cabinet at an appropriate position.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a front view showing a main part of a structure for mounting a CRT on a cabinet according to an embodiment of the present invention, FIG. 2 is a sectional view taken along the line AA of FIG. 1, and FIG. FIG. 7 is a perspective view showing a state in which a CRT is attached to a cabinet in the structure, and portions corresponding to those of the conventional example shown in FIGS. 4 to 6 are given the same reference numerals.

1 to 3, 1 is a CRT, 2
Frame unit cabinet, 2a is, 2b are CRT mounting portion, 2b ₁ are mounting base, 2b ₂ are reinforcing ribs, 2b ₃ fastening boss portion, explosion-proof band 4, the mounting bracket 6, 6a are fixed portion,
6b is an overhanging portion, 6c is an insertion hole, and 8 is a tightening bolt. The basic construction of these is the same as in the conventional example shown in FIGS.

The feature of this embodiment is that the C of the cabinet 2 is
The RT mounting portion 2b and a part of the shape of the mounting bracket 6 are improved. That is, the CRT mounting portion 2b of the cabinet 2 from its mounting base 2b ₁ toward the mounting bracket 6 side plate-like movement restricting rib 2b ₄ are projected, the movement restricting rib portion 2b ₄ is mounted base portion 2b ₁ is formed so as to traverse obliquely, while the mounting member 6 is engaged with the movement restricting rib 2b ₄ from the end of the protruding portion 6c toward the CRT mounting portion 2b side. That is, the piece 6d is integrally formed.

In the above structure, when the CRT 1 is attached to the cabinet 2, the engagement pieces 6d of the respective attachment fittings 6 are engaged with the movement restricting rib portions 2b ₄ of the cabinet 2, respectively. Thus, the axial center of the fastening boss portion 2b ₃ of the insertion hole 6c and the cabinet 2 of the mounting bracket 6 is naturally aligned to match, Habukeru the trouble of both alignment.

Then, the tightening bolt 8 is attached to the fitting 6
After inserted through the insertion hole 6c, it is fixed by tightening the fastening bolt 8 the fastening boss portion 2b _3, in this case, even if there is play allowance in the insertion hole 6c, the movement of the mounting member 6 is movement restricting rib Since it is regulated by 2b ₄ , the CRT 1 will not be displaced with respect to the cabinet 2 even if a tightening torque or the like is applied. Therefore, the CRT 1 is always attached to the cabinet 2 at an appropriate position.

[0015]

As described above, according to the present invention, not only the positioning when mounting the CRT on the cabinet becomes easy, but also
CR position is prevented from occurring when mounting the CRT
Since the T is always properly fixed to the cabinet,
This has the effect of improving the mounting workability.
