Abstract

PURPOSE: To prevent a packing from dropping when a casing for storing therein a key and a handle is attached to a door, by integrally attaching the packing to the casing so as to seal between an attaching hole in the door and the casing. CONSTITUTION: A casing 3 for storing therein a key 10 and a handle 17, which is attached to a door 7 of a distribution panel storage box or the like, is integrally attached thereto with a packing 1 having a flange part 16. Further, the casing 3 with the packing 1 is fitted in a hole 15 which is formed in the door 7 for attaching the casing 3, and the flange part 16 of the packing 16 is fastened by a flange part 4 of the casing 4 so as to effect sealing, and accordingly, the packing 1 is prevented from coming off and being lost. Thereby, it is possible to enhance the waterproof ability and the working ability.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle for a waterproof type door used in a switchboard storage box or the like.

[0002]

2. Description of the Related Art In a conventional waterproof door handle device,
A water impermeable cover is fitted from the back side to the entire casing that is fitted from the front side into the door mounting hole, and a flange portion is provided on the entire circumference of the front end portion of the water impermeable cover. The flange of the impermeable cover was tightened between the entire surface and the surface.

However, since the water-impermeable cover as the waterproof member is fitted to the main body of the casing, it may fall off or be lost during installation and removal at the site.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a waterproof door handle device in which the waterproof member is not attached or detached at the site, so that there is no risk of the waterproof member falling off. .

[0005]

The waterproof door handle device according to the present invention will be described below with reference to the reference numerals in the accompanying drawings. The casing 3 is fitted into the mounting hole 15 of the door 7 from the front side. The film 1 is attached from the back side or molded integrally with the casing 3, and the flange part 16 of the packing film 1 is tightened between the front end flange part 4 of the casing 3 and the front face 7a of the door 7.

[0006]

In this waterproof door handle device, the flange portion 16 of the packing film is brought into close contact with the front surface of the door 7 so that the material 1 blocks the mounting hole 15 locking hole 10 of the door 7 and locks rainwater and the like. Prevent entry into the door 7 through the hole 10.

[0007]

In the embodiment shown in FIGS. 1 to 4, a shaft cylinder portion 5 into which a locking shaft 20 is inserted is provided at the base end portion of a casing 3, and a lock housing portion is provided at the end portion of the casing 3. 9 and a lock hole 11 communicating therewith are provided. On the front side of the casing 3, a front recess 6 is provided in which a handle 17 is retractably housed.

Since the packing film 1 is adhered to the entire back surface of the casing 3 or integrally molded, the locking hole 1
Intrusion of rainwater etc. via 1 is also prevented. At the center of the back surface of the packing film 1, an escape hole portion 13 for a screw hole 12 for fixing to the door 7 is provided. An escape hole portion 14 for the shaft cylinder portion 5 is provided at the rear end portion of the back surface of the packing film 1. Although the screw hole 12 does not penetrate the front concave portion 6 of the casing 3,
The shaft tubular portion 5 penetrates the front recessed portion 6. Therefore, an O-ring 8 is provided as a waterproof member between the shaft tube portion 5 and the locking shaft 20.
Has been inserted.

Instead of the O-ring 8, as shown in FIG. 7, the packing film 1 is extended to form an annular rib portion 23 inside the bearing cylinder 5, and the annular rib portion 23 is closely attached to the locking shaft 20. It can also be waterproof. The handle 17 has a base end portion pivotally attached to a pivot bearing 21 of a locking shaft 20 by a pivot shaft 19, a finger hooking projection 22 is provided on the front surface of the base end portion, and a coil spring 18 is fitted in the pivot bearing 21.

In another embodiment shown in FIGS. 5 and 6, the packing film 1 is provided only on the flange portion 4 of the casing 3.

[0011]

As described above, in the waterproof door handle device of the present invention, the packing film 1 as a waterproof member is attached to the casing 3 fitted into the mounting hole 15 of the door 7 from the front side or the casing 3 is used as a waterproof member. Since it is integrally molded with the product, there is no risk of the waterproof member falling off or getting lost due to on-site installation or removal.
