In this case, the retractable panel 3 has a door 7 with a meter reading window on one side and a door 8 on the other side, and a housing part 9 inside the door 7 with a meter reading window is fixed to a wooden base 10 and sealed. A necessary integrating power meter 11 is housed in a screwed state on a mounting plate 12, and a retractable switch 14, a timer 15, etc. that do not need to be sealed are housed in a housing section 13 inside the door 8. The housing section 9 is housed in a state where it is screwed to the mounting plate 16, and the storage box 17, which is open at the rear and has a door 7 with a meter reading window on the front side, is attached to the retractable pole 2 with its rear face facing the retractable pole 2.
The storage section 13 has a rear-open storage box 18 having a door 8 on the front surface and is fixed to the retractable pole 2 with the rear surface facing the rear surface of the storage box 17 with the retractable pole 2 in between. It is composed of The gap between the storage boxes 17 and 18 is U-shaped with both ends bent outward and the outward bent parts 19a and 20a.
Two rubber gaskets 19 and 20 formed so as to be curved along the retraction pole 2 are placed in the storage box 17,
18 and the rear edges of the storage boxes 17 and 18 from both sides of the retractable pole 2.
By tightening the circumferential grooves 19b and 20b of a and 20a with metal fittings or belts (not shown), the storage box 1
7, 18 and the retractable pole 2 are waterproofed.

Next, a specific mounting structure of the retracting board 3 to the retracting pole 2 will be explained with reference to FIGS. 6 and 7. That is, in this mounting structure, a mounting band 21 fixed to the inner surfaces of two parallel mounting plates 12 and 16 is screwed to the retracting pole 2, and a mounting piece 22 is spot-welded to the inner surface of the storage box 17.
The storage box 17 is fixed by screwing the mounting pieces 23 to the peripheral edge of the mounting plate 12, and the storage box 18 is fixed by screwing the mounting pieces 24 and 25 spot-welded to the inner surface of the storage box 18 to the mounting plate 16. The wooden base 10 with the integrated power meter 11 attached is screwed to the center of the mounting plate 12, the retractable switch 14 and the timer 15 are screwed to the center of the mounting plate 16, and the storage box is fixed. Concave stepped portion 17 on the trailing edge of 17, 18
Rubber gaskets 19 and 20 are fitted into a and 18a to tighten the outwardly bent portions 19a and 20a.

One side of the door 7 with a meter reading window is hinged to one side of the front opening edge of the storage box 17, and the other side has a headed rotating shaft 27 passing through it from the front surface to the back surface, and the shaft portion of the headed rotating shaft 27 is attached to the other side. A locking fitting 26 is fixed to the tip of the head, which engages and disengages from the other side of the front opening edge of the storage box 17 by rotation of the headed rotation shaft 27, and the rotation of the headed rotation shaft 27 is as shown in FIG. As shown in FIG. 1, an inserted engaging portion 28a of the operating handle 28 that can be freely inserted into and removed from the handle inserted engaging portion 27a (see FIG. 12), which is a radial hole provided in the circumferential surface of the head of the headed rotating shaft 27. is inserted, and in this state, the handle portion 28b of the operating handle 28 is manually rotated about the headed rotating shaft 27. In this case, the operation handle 28 has a substantially Z-shaped bent plate shape in which the insertion engagement part 28a is bent at a different level from the handle part 28b, and the handle part 28b is bent from the insertion engagement part 28a. When the handle is in the upper position, insert the engaging part 27a
By inserting the engagement part 28a into the handle part 28b, the handle part 28b is raised above the door 7 with a meter reading window, so that it can be easily rotated. The door 8 is similarly configured.

Further, on the other side of the door 7 with a meter-reading window, a hole 29 for inserting a sealing screw is formed, and in the vicinity thereof, a cut-and-raised part 30 for sealing is formed with both ends joined to the door 7 with a meter-reading window. , after closing the door 7 with a meter reading window, the sealing screw 31
into the storage box 17 through the sealing screw insertion hole 29, and connect a wire or the like to the sealing cut-and-raised part 30 and the through-hole 31a of the head of the sealing screw 31.
The door 7 with a meter reading window is sealed by locking the wire 1 and tying both ends of the wire.

On the other hand, the overhead wire 32 is hooked onto the overhead wire retaining insulator 5 and then passed through the hole (not shown) in the cap 6 into the inside of the lead-in pole 2, and is located at a point located inside the lead-in panel 3 of the lead-in pole 2. The electric wire 33 connected to the overhead wire 32 from the out cap 34
is pulled out into the retraction board 3 through the retraction pole 2
After connecting to the watt-hour meter 11, the lead-in switch 14, and the timer 15 using both sides of the wiring space, the wire is connected to the lead-in pole 2 from a point located inside the lead-in panel 3 via an outcap (not shown). It is passed through the inside of the lead-in pole 2 and guided underground to a distribution board (not shown) in the building.

However, in such a configuration, the configuration for sealing the door 7 with a meter reading window is very complicated, and the operation handle 2 for opening/closing the door 7 with a meter reading window is very complicated.
8 was separate, so this operation handle 2
There was a risk of losing 8.

Therefore, an object of this invention is to provide a door sealing structure that can be simplified and prevent the operating handle from being lost.

A power supply lead-in device to which an embodiment of this invention is applied is shown in FIGS. 9 to 12. That is, as shown in FIGS. 9 to 11, this power supply lead-in device has a sealing hole 36 formed in the handle portion 28b of the operation handle 28, and a door with a meter reading window when the locking fitting 26 is engaged. A sealing bridge-like cut-and-raised part 35 is formed at a location corresponding to the sealing hole 36 of 7 with both ends thereof joined to the door 7 with a meter-reading window, and this sealing bridge-like cut-and-raised part 35 is formed at a location corresponding to the sealing hole 36 of 7. The sealing hole 3 of the sealing bridge-like cut-and-raised part 35 is inserted by inserting the part 35 into the sealing hole 36 and passing the sealing ring 37 through the sealing bridge-like cut-and-raised part 35.
It is being prevented from coming out from 6. In this case, the operation handle 28 is inserted into the insertion engagement part 28 with the handle part 28b being lower than the insertion engagement part 28a.
8a is inserted into the handle insertion engagement portion 27a of the head of the headed rotating shaft 27.

Further, the rotation operation of the headed rotating shaft 27 is performed using the handle portion 28b of the operating handle 28, as shown in FIG.
Insert the insertion engagement part 28a into the handle insertion engagement part 27a of the head of the headed rotating shaft 27 with the insertion engagement part 28a positioned above the insertion engagement part 28a, and in this state hold the handle part 28b to open the operating handle 28.
This is done by rotating.

As a result of this configuration, the conventional sealing screw 31
is no longer necessary, simplifying the sealing structure. Also,
Since the operating handle 28 is used for sealing, there is no possibility of losing the operating handle 28.

As described above, the door sealing structure of this invention includes a door whose one side is hinged to one side of the door frame, and a handle insertion engagement part on the circumference of the head, which connects the other side of the door. A headed rotating shaft that penetrates from the front surface to the back surface, and a chain that is fixed to the shaft portion of the headed rotating shaft on the back side of the door and that engages and disconnects from the other side of the door frame as the headed rotating shaft rotates. A lock fitting and a handle insertion engagement portion of the head of the headed rotation shaft, which is approximately a Z-shaped bent plate shape in which the insertion engagement portion that is inserted into the handle insertion engagement portion is formed at a different level with respect to the handle portion. The headed rotation shaft is rotated by rotating the handle portion about the headed rotation shaft while inserting the insertion engagement portion into the insertion portion with the handle portion placed above the insertion engagement portion. an operating handle that can be rotated and inserted or removed; a sealing hole provided in a handle of the operating handle; and an insertion engagement portion that is inserted into the handle insertion engagement portion when the lock fitting is engaged with the door frame. When the handle is inserted in a position lower than the inserted and engaged part, the door is cut and bent at a location corresponding to the sealing hole of the door with both ends joined to the door and inserted into the sealing hole. A sealing bridge-like cut-and-raised portion to be inserted through the sealing bridge-like cut-and-raised portion, and a sealing ring that is passed through the sealing bridge-like cut-and-raised portion to prevent the sealing bridge-like cut-and-raised portion from coming out of the sealing hole. This has the effect of simplifying the sealing structure and preventing loss of the operating handle.
