DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in detail below based on the drawings showing one embodiment. 1 to 5 show an example in which the present invention is applied to a casing of a telephone exchange, and this electronic device casing 1 includes a casing body 10 and a lid 20. As shown in FIG.

A replacement device (not shown) is accommodated in the housing body 10, and a rectangular opening 11 is formed in the wall surface 10a. In addition, a lid body 20 is attached to the hinge pins 12, 12 provided at the left and right lower portions of the wall surface 10a.
Pin receiving members 21, 21 provided on the left and right sides of the lower edge (one edge) 20A are fitted together, so that the lid 20 can be attached to the housing body 1 in a manner that allows the opening 11 to be opened and closed.
It is swingably supported at 0.

As shown in FIG. 2, a lock plate 30 as a first locking member on the lid side is arranged on the left side (one corner) 20a of the upper edge (other edge) 20B of the lid 20. There is. This lock plate 30 has an L-shape having a claw part 30a and a lever part 30b, and is attached to a rotation shaft 31a of a cylinder lock 31 fixed to the lid body 20, as shown in FIG. ing.

On the other hand, as shown in FIGS. 1, 4, and 5, a lock bracket 32 serving as a first locking member on the main body side is fixed to the wall surface 10a of the housing main body 10. This lock bracket 32 has a claw portion 3 of the lock plate 30.
A locking claw 32a that engages with the lock plate 30, the cylinder lock 31, and the lock bracket 32 constitute a first locking means 100.

As shown in FIGS. 1 and 2, a connecting rod 40 serving as interlocking means is connected with a pin to the lever portion 30b of the lock plate 30, and this connecting rod 40 is fixed to the lid body 20. Guide hole 5 of guide plate 50
0a, upper edge (other edge) 20B of the lid body 20
It extends along. Further, the tip end 40a of the connecting rod 40 is located on the right side (the other corner) 20b of the upper edge (the other edge) 20B of the lid 20, as shown in FIG. It constitutes a stop member.

On the other hand, as shown in FIGS. 1, 4, and 5, a rod stopper plate 51 serving as a second locking member on the main body side is fixed to the wall surface 10a of the housing main body 10. This rod stopper plate 51 is provided with a fitting hole 51a into which the tip end 40a of the connecting rod 40 is fitted.
The tip end 40a of the connecting rod 40 and the rod stopper plate 51 constitute a second locking means 200.

Furthermore, as clearly shown in FIG.
On the inner surface of the housing body 1, magnetic catches 60, 60 are provided on both left and right edges, respectively.
These magnetic catches 60,
Receptacle fittings 61, 61 are attached at positions corresponding to 60.

In the electronic device housing 1 configured as described above,
When the lid body 20 is open, the lock plate 30 and the connecting rod 40 are shown as solid lines in FIG. 1 (broken lines in FIG. 2).
They occupy the unlocked positions indicated by .

When the lid 20 is closed, the magnetic catch 60 attracts the receiving metal fitting 61 by magnetic force, so that the lid 20 is held on the housing body 10. In addition,
The appearance when the lid body 20 is closed is no different from the conventional electronic device case shown in FIG. After closing the lid body 20,
When the cylinder lock 31 is locked with a key (not shown), the lock plate 30 rotates from the unlock position to the lock position shown by the solid line in FIG. By engaging with the locking pawl 32a of the lock bracket 32, the first locking means 100 enters the locked state.

Further, as the lock plate 30 rotates, the connecting rod 40 moves from the unlocked position to the position shown in FIG.
to the lock position shown by the solid line, and the connecting rod 4
0 fits into the fitting hole 51a of the rod stopper plate 51, thereby locking the second locking means 20.
0 is also in the locked state like the first locking means 100.

[0022] Thus, the lid body 20 has the hinge pin 1
2 and the pin receiving member 21, both corners of its lower edge are supported by the housing body 10, and the first
Both corners of the upper edge of the locking means 100 and the second locking means 200 are supported by the housing body 10, so that they will not easily bend even when a large external force is applied. Moreover, by simply locking the cylinder lock 31, the first locking means 100 and the second locking means 20 can be locked.
0 are locked at the same time, the work itself can be performed extremely simply as in the past.

The electronic equipment casing according to the present invention is not only applicable to the casing of the telephone exchange shown in the embodiment, but can also be widely and effectively applied as the casing of various electronic equipment such as measuring equipment. It goes without saying that it can be done.

[0024]

Effects of the Invention As detailed above, the present invention includes a casing body having an opening formed in the wall surface, and a lid that is pivotally supported at one edge on the casing body and is provided in a manner that it can be opened and closed to cover the opening. body and
A first lid-side locking member lockably provided at one corner of the other edge of the lid; and a main-body-side first locking member that is fixed to the housing body and engages with the lid-side first locking member. a first locking means consisting of; a second lid-side locking member provided at the other corner of the other edge of the lid; and a main body that is fixed to the casing body and engages with the lid-side second locking member. a second locking member on the side; and a first locking member on the lid side in such a manner that the second locking member on the lid side is engaged and disengaged in synchronization with the locking and disengaging operation of the first locking member on the lid side. An electronic device casing is constituted by an interlocking means that connects the member and the lid-side second locking member to each other.

According to this configuration, by bringing the first locking means into the locked state, the second locking means is also brought into the locked state via the interlocking means.

That is, according to the electronic device casing according to the present invention, by simply locking the first locking means, the two corners of the lid can be secured to the casing via the first locking means and the second locking means. Since it is locked to the main body of the device, the lid can be securely locked to the main body of the device without any complicated work, and it is possible to prevent foreign objects from accidentally entering the device case.
