Description

[Detailed Description of the Invention] (a) Field of industrial use The present invention relates to a locking position sealing mechanism that is attached to an electrical equipment storage case such as a switchboard or a distribution board.

(B) Conventional technology Conventionally, as a sealing mechanism of a locking device for an electric device storage case, as described in Japanese Utility Model Laid-Open No. 58-167173, a front plate portion provided at a front end of a key body and a front surface of the front plate portion are provided. Protruding pieces with sealing member insertion holes are provided at required peripheral edge positions corresponding to the cover plate that is openably and closably provided to cover, and the protruding piece portions are overlapped with each other to insert wire or the like into the sealing member insertion hole. There was a thing which inserts a sealing member and seals.

Also, Japanese Utility Model Publication No. 58-167174 (Japanese Utility Model Publication No. 62-36934)
As described in 1, at the corresponding peripheral edge required positions of the front plate and the cover plate, holes for inserting a set screw are provided,
There has been a method in which a set screw is screwed into these holes and a sealing member such as a wire is inserted into the sealing member insertion hole of the set screw head to seal.

(C) Problems to be solved by the invention In the conventional sealing device for the locking device for the electric equipment storage case described above, the former overlaps the projecting pieces with the sealing member insertion holes, and inserts a sealing member such as a wire into the sealing member insertion hole. Since it is inserted and sealed, it is inconvenient to handle, for example, the sealing operation of passing a wire or the like through the ultrafine pores and the unsealing operation thereof are troublesome.

In the latter case, after closing the cover plate, a set screw is screwed into the insertion hole, and a sealing member such as a wire is inserted into the sealing member insertion hole of the set screw head for sealing. Although the sealing function is more reliable than the former, there are drawbacks that the sealing operation and the opening operation are more troublesome, and the number of parts is large and the processing cost is high accordingly.

(D) Means for Solving the Problems In view of the above-mentioned drawbacks of the sealing mechanism of the conventional locking device for an electric device storage case, a device having a simple structure, a reliable sealing function, and a one-touch sealing and opening operation are provided. The structure is such that a rotating body with a key insertion hole provided at the front end of the lock body is provided with a rotating body lid that covers the front surface of the rotating body and closes the key insertion hole so as to be openable and closable. In the locking device, a protrusion having a sealing member insertion hole is provided at a required position on the peripheral portion of the rotating body, and a protrusion having a sealing member insertion hole that abuts and abuts the protrusion having the sealing member insertion hole. A sealing mechanism for a locking device, characterized in that a protrusion cap provided on a moving body lid is covered with a sealing cap so that both protrusions can be tightly fitted together.

E action The front of the rotating body is covered by the rotating body lid, and the protrusion of the rotating body with the sealing member insertion hole and the protrusion of the rotating body lid with the sealing member insertion hole are brought into close contact with each other. Close the sealing cap with and seal. Further, it is also possible to insert a sealing member between the sealing member insertion holes of both the protrusions for sealing.

F. Embodiment An embodiment of the sealing mechanism of the locking device according to the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 is a key body, and a rotating body lid 4 provided on the front end of the rotating body 3 with a key insertion hole 2 covers the front surface of the rotating body 3 to close the key insertion hole 2. Is provided
A pivot 9 that allows the rotary body lid 4 to be opened and closed is inserted into both peripheral edge portions of the rotary body 3 and the rotary body lid 4. Then, a half-cylindrical projection 6 with a sealing member insertion hole 5 is provided on the lower peripheral edge of the rotating body 3, and a half with a sealing member insertion hole 7 that abuts and abuts the half-divided surface of the projection 6. A columnar protrusion 8 is provided on the rotary body lid 4, and a sealing cap 10 that is tightly fitted to both protrusions 6 and 8 when the respective half-divided surfaces of the protrusions 6 and 8 are in close contact with each other is provided. .

The sealing mechanism configured as described above is used for the door A of the case body B.
The key body 1 is attached so that the rotating body 3 is on the front surface of the door A, and the rotating body lid 4 covering the front surface of the rotating body 3 is opened to release the blockage of the key insertion hole 2 and the key insertion The key handle is inserted into the hole 2, and the door A is locked and unlocked by rotating the key handle. When the door A is locked after the door A is locked, the key handle is pulled out from the key insertion hole 2 and the pivot body lid 4 is rotated about the pivot shaft 9 so as to cover the front face of the pivot body 3 and the key is closed. The insertion hole 2 is closed. Then, the half-divided surfaces of both the projecting portions 6 and 8 are brought into close contact with each other, and in this state, the sealing cap 10 is brought into close contact with one touch for sealing. In this way, the sealing cap 10 is tightly fitted to both the projections 6 and 8 that are in close contact with each other, so that the sealing function is reliable.

When opening, after easily removing the sealing cap 10,
Reverse the above procedure.

In this way, since the sealing cap 10 can be used for sealing or opening with one touch, it is convenient without requiring any trouble.

Also, without using the sealing cap 10, both the protrusions 6 and 8
It is also possible to insert a sealing member such as a wire 11 between the sealing member insertion holes 5 and 7 and bind and fix it for sealing.

Although both the rotating body and the rotating body lid of the present invention have a semi-cylindrical cylindrical shape, the present invention is not limited to this, and as shown in FIGS. 4 (a) and 4 (b). It may be formed in a prismatic shape.

G. Effect of the Invention As described above, the sealing mechanism of the locking device of the present invention has a structure in which both the protrusions of the rotating body and the lid of the rotating body are abutted and brought into close contact with each other, and the sealing cap makes one-touch engagement. It is simple, convenient and convenient for sealing and unsealing operations, and has a reliable sealing function.
