Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a mounting structure for a door of an electronic device housing.

(Prior Art) Since an operation panel or a power supply unit mounted on an electronic device is always operated or replaced by an operator or a tester, it is required that a portion to be operated or replaced be in an open state. On the other hand, in order to prevent dust from entering the inside of the device and erroneous operation of switches and the like, it is desirable that the switch is in the closed state except during operation and replacement. For this reason, in general, doors often have an opening / closing structure using hinges, bearings, and the like.

FIG. 10 shows a conventional example using a hinge, in which 1 is a main body of an electronic device housing, 1a is a recess thereof, 2 is a door, and 3 is a hinge.

FIG. 11 shows another conventional example of the bearing structure. The same parts as those in FIG. 10 are designated by the same reference numerals, 4 is a support metal fitting fixed to both ends of the door 2, and 1b is a main body 1. It is a bearing provided in. The support shaft fitting 4 is provided on the door by screws or the like.
FIG. 12 is a side sectional view of the conventional example shown in FIG. As shown in the figure, the hinges 3 are provided on both sides of the door 2 and the main body 1 with screws or the like, and the door 2 is often made of a resin material such as acrylic for reasons of appearance and functionality. .

(Problems to be solved by the invention) However, in the door mounting structure in the electronic device housing as described above, a tool such as a driver is required when the door 2 is attached and detached, and the assembling is complicated, so that the number of assembling steps is large. Besides,
During the testing of the device, the door is often open, and on the contrary, there is a problem that the door has a harmful effect, for example, there is a risk of damaging the door, and that the work is difficult to perform. .

It is an object of the present invention to provide an excellent device that improves workability and simplifies handling by eliminating the problems that the above-mentioned prior art has such as complicated assembly and a large number of assembly steps. To do.

(Means for Solving the Problems) The structure of the present invention for achieving the above object will be described with reference to FIGS. 1 to 8 corresponding to the embodiments. In the mounting structure of the protection door 12 provided in the recess 11a of the electronic device body 11, the structure includes the support shafts 12a and 12b protruding from both end portions of the front side.
An insertion hole 13 provided on one of the left and right side walls 11a of the protection door 12 to which the one support shaft 12a is fitted, and the other side of the left and right side walls 11c are provided at positions facing the insertion hole 13. An L-shaped elongated hole 14 including an insertion portion 14c and a guide portion 14b which is formed continuously from the insertion portion 14c and which is inserted through the other support shaft 12b of the protection door 12 and is guided toward the insertion portion 14c. And this L
When the other support shaft 12b of the protection door 12 provided opposite the back side of the elongated slot 14 is moved by the guide portion 14b, the support shaft 12b is pushed by the tip of the support shaft 12b, and the support shaft 12b is guided by the guide portion 14b. And a leaf spring 15 that blocks the movement of the support shaft 12b when it passes through.

(Operation) According to the present invention, since the structure for mounting the protective door such as the operation panel as described above is provided, the support shaft 12a is slanted with the door 12 standing and the support shaft 12a is inserted into the recess 11a of the device body 11. While inserting into the hole 13, the support shaft 12b is inserted into one end 14a of the L-shaped elongated hole 14 of the main body 11 and moved in the guide portion 14b toward the insertion portion 14c.
At this time, the tip of the support shaft 12b moves while pushing the leaf spring 15. When the support shaft 12b passes through the guide portion 14b and reaches the insertion portion 14c, the leaf spring 15 returns to prevent the support shaft 12b from moving. This allows the door 12 to be attached to the main body 11 easily and securely. The door 12 can be easily removed from the main body 11 by performing the reverse operation. That is, the number of assembling steps is reduced and the workability is improved, so that the above problems are eliminated.

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