Abstract

PROBLEM TO BE SOLVED: To fix a front panel easily in safety to a housing by providing an engaging part on the front face of the housing in at least one of upward or downward direction and providing, on the rear surface of the front panel, with an engagement receiving part and a fixing means, respectively, in the upward and downward directions. SOLUTION: When a front panel 20 is inserted into a housing 11, the engagement receiving part 23 of a subchassis 21 screwed to the front panel 20 is inserted into the through hole 16 at an engaging part 14 and a protrusion at the engaging part 14 is inserted into the through hole 24 at the engagement receiving part 23 thus engaging both parts 14, 23. Subsequently, holes 25 made at the opposite upper ends of the subchassis 21 are aligned with the threaded holes of fixed screw receivers 17 made at the opposite upper ends of the housing 11 and inserted with screws thus fixing the front panel 20 to the housing 11. Consequently, the front panel 20 can be fixed easily in safety to the housing 11 without lifting or turning over the housing 11.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for mounting a front panel on a housing of a large-sized amplifier or the like.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional mounting structure of this type, in which 1 is a housing of a large-sized amplifier or the like, 2 is a front panel, and 3 is an upper surface and a lower surface of a front portion of the housing 1. Are screws for fixing the front panel 2. Depending on the type, there may be a sub-chassis or the like in addition to the housing 1.

[0003]

However, when the front panel 2 is screwed from the upper surface and the lower surface of the housing 1 as described above, a relatively heavy housing is lifted or turned upside down. Therefore, there is a problem that it is difficult to obtain a certain quality because the product being manufactured is damaged or excessive work is required.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems. A front panel mounting structure capable of safely and easily mounting a front panel on a housing without lifting or turning over the housing. The purpose is to provide.

[0005]

In order to achieve the above object, a front panel mounting structure according to the present invention has an engaging portion in one of the vertical direction on the front surface of a housing, and a vertical direction on the rear surface of the front panel. One of which has an engagement receiving portion that engages with the engagement portion and a fixing means that fixes the other in the up and down direction to the other in the up and down direction of the front surface of the housing. In one of the directions, after the engagement portion and the engagement receiving portion are engaged with each other, only the other in the up-down direction may be fixed by the fixing means, so that the housing is not lifted or turned over, and Panels can be easily attached.

[0006]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is an exploded perspective view showing a front panel mounting structure according to an embodiment of the present invention, and FIG. 2 is a perspective view showing a state in which they are assembled.

In FIG. 1 and FIG. 2, reference numeral 11 denotes a casing of a large-sized amplifier or the like, which is provided with a front plate 13 at a lower portion of a front surface thereof for connecting between casing side plates 12, and is connected to three portions of the front plate 13. A joint 14 is provided. The engagement portion 14 is formed of a through hole 16 having a vertical projection 15 provided on the inside. A fixing screw receiver 17 having a screw hole is provided on each of the side plates 12 on both upper sides of the front surface of the housing.

Reference numeral 20 denotes a front panel, and reference numeral 21 denotes a sub-chassis. The sub chassis 21 is the front panel 2
No. 0 is fixed to the back surface by screws 22. Subchassis 2
1 has an engagement receiving portion 2 which engages with the engagement portion 14.
Reference numeral 3 extends in the horizontal direction, and a through hole 24 is provided in the engagement receiving portion 23.

In order to attach the front panel 20 to the housing 11, first, as shown in FIG. 2, the engagement receiving portion 23 of the sub-chassis 21 screwed to the front panel 20 Inserted into the through hole 16,
The engagement portion 14 and the engagement receiving portion 23 are engaged with each other by inserting the projection 15 of the engaging portion 14 into the through hole 24 of the engagement receiving portion 23.

FIGS. 3 and 4 are enlarged views showing a state in which the engaging portion 14 and the engaging receiving portion 23 are engaged with each other.
5 and a contact portion B between the front plate 13 and the base of the engagement receiving portion 23 of the front panel.

Thereafter, as shown in FIG.
The holes 25 provided at both upper ends of the housing 11 and the screw holes of the fixing screw receivers 17 provided at both upper ends of the housing 11 are screwed together and fixed with screws 26.
Attached to.

According to the present embodiment configured as described above, the engagement receiving portion 23 of the front panel 20 and the engagement portion 14 of the housing 11 are engaged from the front surface of the housing 11, At the top, the screw 26 only needs to be screwed in with a screwdriver, so that the front panel can be easily attached without moving the housing.

In the embodiment, the engaging portion is arranged at the lower portion of the front surface of the housing and is screwed at the upper portion. However, the engaging portion and the screwing portion may be upside down. . In addition, the number of the engaging portions is not particularly limited, but providing three or more places is structurally stronger.

[0015]

As described above, according to the present invention,
Without lifting or turning over the housing,
Since the front panel can be safely and easily attached to the housing and a structurally strong assembly can be obtained, high-quality products can be manufactured at low cost.
