The display elements 181 to 183, 186 to 190, the graphic displays 184 and 185, and the touch switch 191 are all operated by commands from the control unit 19.

  Further, two guides 83 having a substantially semicircular arc shape having a convex cross section are formed along the peripheral edge portion of the disk-shaped plate surface of the rotating member 81, and the disk-shaped plate surface between the guides 83. Two fixed claws 84 having an inverted L-shaped cross section are formed so as to be respectively planted on the disk-shaped plate surface.

  The rotating member support member 85 is detachably provided at one end of the power converter unit storage container 01. The outer periphery of the guide 83 of the rotating member 81 is fitted, and a circular hole 86 is formed so that the rotating member 81 can rotate. The four guides 87 having a ¼ arc-shaped cross-sectional convex shape are formed on the same circumference along the edge of the circular hole 86, and there are four guides 87 respectively existing between the guides 87. The two fixing claws 84 included in the rotating member 81 are fitted into the positioning portion 88, and the rotating member 81 is supported so as to be rotatable by 90 degrees.

  6 and 7 both show a state in which the rotating member 81 and the rotating member support member 85 are disassembled. FIG. 6 shows the front side of the rotating member 81 and the rotating member support member 85, and FIG. The back side of the rotation member 81 and the rotation member support member 85 is shown. 8 and 9 both show a state in which the rotating member 81 and the rotating member support member 85 are assembled. FIG. 8 shows the front side of the rotating member 81 and the rotating member support member 85, and FIG. The back side of the rotation member 81 and the rotation member support member 85 is shown. 10 and 11 show a state in which the rotating member 81 and the rotating member support member 85 are assembled, and the rotating member 81 is rotated approximately 45 degrees. FIG. 10 shows the rotating member 81 and the rotating member. The front side of the support member 85 is shown, and FIG. 11 shows the rotary member 81 and the back side of the rotary member support member 85. A ventilation port 80 is formed on the side surface of the rotating member support member 85 where the state display unit 18 is not formed.

  Since the power converter unit CU and the storage battery unit B are configured as described above, they can be installed in various states as shown in FIG. Although one storage battery unit B is the basic configuration for one power converter unit CU, FIG. 12A shows a state in which one power converter unit CU and three storage battery units B are all placed vertically. 12 (b) is an example in which one power converter unit CU and three storage battery units B are all installed horizontally, and FIG. 12 (c) shows one power. This is an example in which the converter unit CU and the three storage battery units B are all installed in a horizontally placed state and further stacked in a vertically stacked state. In this case, the rotation member 81 having the display element of the state display unit 18 is easily rotated by 90 ° according to the installation state, that is, the display unit of the rotation member 81 with respect to the installation (installation) surface of the power converter unit CU. Since the arrangement direction of the characters can be made parallel, it is easy to see the display unit that displays the operation state of the uninterruptible power supply.

  In addition, when replacing and repairing the storage battery unit B, it is not necessary to remove the storage battery cover as in the prior art. The storage battery unit B can be easily replaced and expanded.

Furthermore, since the storage container of the power converter unit CU and the storage container of the storage battery unit B are substantially the same, workability associated with product manufacture is good.

  Further, since the state display portion is formed and rounded at the corner portion of the storage container 01 of the power converter unit CU and close to the display portion of the rotary member support member 85, the direction of the rotary member support member 85 is determined. Easy to check the sex.

  A circular hole 86 is formed in the rotary member support member 85 so that the rotary member 81 can rotate. Along the edge of the circular hole 86, four guides 87 having a ¼ arc-shaped cross-sectional convex shape are formed. By forming the groove in the circumferential direction at the root portion, the rotating member 81 rotates smoothly.

  The fixing claw 84 of the rotating member 81 is formed so as to be perpendicular to a circle virtually drawn on the plate surface of the rotating member 81, and is a positioning portion 88 existing between the guides 87 of the rotating member support member 85. Thus, the end portion 87a of the one guide 87 is formed in a triangular shape in cross section, and the end surface of the other guide 87 is a right-angled surface 87b with respect to the circumference. When the fixed claw 84 is fitted in the positioning portion 88 existing between the guides 87 of the rotating member support member 85, a click feeling is obtained, and the positioning associated with the rotation operation of the rotating member 81 can be confirmed.

  A plurality of slits are formed in the outer end surface edge of the rotating member support member 85 shown in FIG. 7 and joined to a connecting convex portion (not shown) formed on one outer end surface edge of the storage container body 011. 89 is formed, and the upper corner (in FIG. 7), which is one corner of each cut groove 89, has a stepped portion 89a having two perpendicular planes, and a hole formed in the connecting convex portion. The lower side (in FIG. 7), which is the other corner of each cut groove 89, is inserted into a notch (not shown), and a substantially U-shaped cut 89b is formed, and the other outer end face edge of the storage container body 011 Rotating member support shown in FIG. 7, which is joined to a connecting recess (not shown) formed in the portion and further engages with a connecting recess (not shown) at the edge of the storage container body 011 A connecting convex portion 90 of the member 85 is formed. As a result, the rotating member support member 85 can be reliably connected (joined) to the storage container body 011 and can be easily separated.

The embodiment described above can be implemented by being modified as follows. As shown in FIG. 13, the roundness formed in the portion near the display portion of the rotating member support member 85 may be eliminated. Also,
Although the state display unit described above is connected to one end of the storage container 85 of the power converter unit CU, the state display unit may be connected to the storage container of the storage battery unit B, and the state display unit is further converted into power. It is good also as a status display device of the uninterruptible power supply which is not connected to the storage container 85 of the storage unit CU and the storage container of the storage battery unit B. Furthermore, although embodiment mentioned above demonstrated the combination of one power converter unit CU and the some storage battery unit B, not only this but the number of power converter units CU and the number of storage battery units B are arbitrary. It may be. Moreover, you may make it rotate easily by forming a hollow etc. in the circumferential surface part of a rotating member.
