Description

[Detailed Description of the Invention] (a) Field of Industrial Use The present invention relates to a panel mounting structure for an electronic device housing, and in particular, in order to facilitate repair work, etc. The present invention relates to a panel mounting structure for an electronic device housing in which the front surface of the housing can be opened by moving the housing.

(B) Conventional technology As a conventional panel mounting structure for this kind of electronic device housing,
For example, there has been one configured as shown in FIG.

In the structure shown in FIG. 5, the sub-panel 2 provided on the front panel 1 and the chassis 3 are fixed and connected using the fixing screws 4 and 5.

Further, in the panel mounting structure shown in FIG. 5, as shown in FIG. 6, after the front panel 1 is pulled out to the front, the front panel 1 is rotated downward to move the front part of the chassis 3. Was configured to be open.

That is, a guide hole 21 for pulling out the front panel 1 is formed in the sub-panel 2, and a fixing screw 5 is screwed into the chassis 3 through the guide hole 21. Therefore, when rotating the front panel 1 to open the front part of the chassis 3, first, the sub-panel 2
And the upper screw 4 fixing the chassis 3 to the chassis 3 are removed. Next, the lower screw 5 screwed into the chassis 3 through the guide hole 21 is warmed. In this state, as shown in FIG. 6, when the front panel 1 is pulled toward you, the guide hole 21 formed in the horizontal direction of the screw 5 serves as an escape hole, changing the contact position with the sub-panel 2 and the front panel 1 Can be pulled out to the front. When the front panel 1 is pushed downward at this position, the front panel 1 is rotationally moved downward around the screw 5 as a spindle, and the front portion of the chassis 3 can be opened.

The front panel 1 can be returned to the original state by performing an operation reverse to the above procedure.

(C) Problems to be solved by the invention However, in the above-mentioned conventional example, when the front panel 1 is returned to the original state, the electric components mounted on the front panel 1 and the chassis 3 are mounted. A force that pushes the front panel 1 outward is exerted under the influence of a wire or the like that electrically connects the electric component. Therefore, it is necessary to tighten the screws 4 and 5 while strongly pushing the front panel 1 toward the chassis 3, and once the front panel 1 is removed, it takes a lot of time to install the front panel 1.

Especially, the guide hole 21 formed in the horizontal direction is attached to the screw 5
When tightening with, the positioning is difficult, and if the front panel 1 is slightly pushed down, the tightening position will be displaced, and the connection position with the chassis 3 will be different from the tightening position by the upper screw 4 and the lower screw 5. Misalignment occurs with the tightening position due to. As a result, there is a risk that the front panel 1 may be attached in an inclined state.

The present invention has been made in view of the above-mentioned problems of the above-described conventional technology, and an object thereof is to make it possible to easily and accurately attach and fix a fixing screw. The present invention is intended to provide a panel mounting structure for an electronic device housing.

(D) Means for Solving the Problems The panel mounting structure of the electronic device housing of the present invention includes sub-panels provided on both sides of the front panel and a chassis for connecting the sub-panels, and is used for fixing the sub-panels to the chassis. In a housing of an electronic device configured such that the front panel 2 can be pulled out toward the front and the front surface of the housing can be opened by warming the screw of, the guide hole formed in the horizontal direction for pulling out the front panel to the front. Section and an L-shaped screw insertion hole consisting of a mounting hole portion for positioning which is continuously formed upward at the end portion of the guide hole portion close to the front panel at symmetrical positions of both sub-panels. The fixing screw is screwed into the chassis through the screw insertion hole.

(E) Action The mounting hole that is formed in the upward direction of the L-shaped screw insertion hole on the sub-panel is used to position the fixing screw when connecting the sub-panel to the chassis, and to warm the fixing screw to warm the front. Acts as an escape hole for fixing screws when lifting the panel.

In addition, the guide hole formed in the horizontal direction acts as an escape hole for the fixing screw when the front panel is pulled out to the front, and the front panel faces downward to open the front surface of the housing. It acts as a support when rotated.

(F) Examples Examples will be described with reference to the drawings.

1 to 4, 1 is a front panel of an electronic device, 2 is sub-panels provided on both sides of the front panel 1, and 3 is a chassis.

Reference numeral 6 denotes an L-shaped screw insertion hole formed on the lower side of the sub-panel 2, which is a guide hole 6a formed for pulling out the front panel 1 and the guide hole 6a close to the front panel 1. It is composed of a mounting hole 6b for positioning which is formed continuously upward at one end thereof. The fixing screw 5 that is screwed into the screw hole 32 of the chassis 3 is inserted into the screw insertion hole 6.

Reference numeral 7 denotes a screw insertion hole formed on the upper side of the sub-panel 2, into which the fixing screw 4 to be screwed into the screw hole 31 of the chassis 3 is inserted.

The L-shaped screw insertion holes 6 and 7 are formed at symmetrical positions on both sub-panels 2, respectively. Also screw holes
The reference numerals 31 and 32 are also symmetrically formed at predetermined positions on both upright wall surfaces of the chassis 3.

In the embodiment of the present invention thus configured, when the front panel 1 is pulled out and the front surface portion of the chassis 3 is opened in order to perform the repair work or the like, the following procedure can be performed.

First, in FIG. 2, the screw 4 that fixes the sub-panel 2 and the chassis 3 is removed. Next, the fixing screw 5 screwed into the chassis 3 is warmed through the L-shaped screw insertion hole 6. In this state, as shown in FIG. 3, when the front panel 2 is lifted, the screw 5 moves from the positioning mounting hole 6b and hits the bent portion between the mounting hole 6b and the guide hole 6a. Here, when the front panel 1 is pulled forward as shown in FIG. 4, the screw 5 changes the contact position with the sub-panel 2 by the guide hole 6a formed in the horizontal direction, and the front panel 1 is pulled out to the front. .
When the front panel 1 is pushed downward at this position, the front panel 1 is rotationally moved around the screw 5 as a spindle, and the front surface portion of the chassis 3 is opened.

On the other hand, when returning the front panel 1 to the original position, contrary to the above-described procedure, the front panel 1 is pushed back in the direction of the chassis 3 and lifted up to the state shown in FIG. When the front panel 1 is pushed down in the state of FIG. 3, the screw 5 is fitted into the mounting hole 6b, and its tightening position is forcibly determined. In this state, the screw 4 can be screwed into the upper screw insertion hole 7 and the screw hole 31 and tightened, and the lower screw 5 can also be tightened to connect and fix the sub-panel 2 and the chassis 3.

(G) Effect of the Invention According to the panel mounting structure of the electronic device housing according to the present invention, the fixing work of the front panel can be simplified and the fixing position can be accurately set. Moreover, the structure is simple, and the structure can be constructed at low cost, so that it is easy to implement.
