[Prior Art] Various sealing devices of this type have been known in the past.
For example, as seen in Japanese Utility Model Publication No. 46-1200, which was invented by the applicant, a rectangular parallelepiped with a recessed hole for attaching it to the head of a screw, etc. is provided with a horizontal hole passing through the center of the recessed hole in the longitudinal direction. and those formed from one single member.
As seen in Publications No. 24311 and No. 24312, it is made of two parts: a crown body that is attached to the head of the screw, and a main body that is fitted to cover this crown body. Drill a horizontal hole in the longitudinal direction,
A locking pin is passed through this horizontal hole and the horizontal hole penetrated through the screw head to seal it.

[Problems that the invention aims to solve] These seals have a simple external shape, and it is difficult to prevent people from destroying them to commit fraud. By replacing the original seal with an imitation one, fraudulent activity can be concealed, making it difficult to detect.

[Means for Achieving the Object] In the present invention, the closed-head cylinder body 2 which is attached to the head of the tightening screw 23 has protruding pieces 3 and 4 protruding from both sides of the outer surface to form an oblong shape. The main body 1 consists of two members: a main body 1 and a cap body 5 attached to the main body 1, and the main body 1 has one longitudinal end open to the outside at one overhanging piece 3, and the other end opened to the outside. A horizontal hole 6 is bored through which the locking pin 16 whose end is closed within the other overhang piece 4 is inserted, and a groove is cut in the top of the closed-head cylinder 2 in a direction perpendicular to the direction of the horizontal hole 6. 7, and also a cap body 5
An oblong window hole 10 is provided at the upper part of the side wall 9 of the closed-head cylinder body 2a, and each of the projecting pieces 3a, 4a
The main body 1 and the cap body 5 are combined in such a manner that the width of the main body 1 is wider than the width of each of the overhanging pieces 3 and 4 of the main body 1, and a space is maintained between the sides of the overhanging pieces 3 and 4. It has an integrated structure that is heat fused.

[Function] The main body 1 has a double structure in which the cap body 5 is attached to the entire surface, and the external shape is complex, which makes it clear that fraudulent acts are difficult, and discourages the act by killing motivation. Further, when a fraudulent act is committed, the slight impact applied causes the cap 5 on the surface to crack at weak points provided at various locations, deterring the continuation of the fraudulent act and leading to its interruption. Further, when a fraudulent act is committed by destroying the sealing device A, it is left broken as it has a complex shape and is difficult to imitate, and from this, the fraudulent act can be detected at an early stage.

If the seal A is to be destroyed when replacing the meter or renewing the meter reading due to a contract change, insert a screwdriver into the window hole 10 provided in the cap body 5 and pry the cap body 5 open. By breaking the main body 1, and then inserting a screwdriver into the cut groove 7 provided in the main body 1 and prying it, the main body 1 can be easily destroyed, the locking pin 16 can be extracted, and the opening/closing lid 18 can be opened.

[Example] In the figure, 1 is a main body formed into an oblong shape with projecting pieces 3 and 4 protruding from both sides of the outer surface of a closed-head cylinder 2 which is attached to the head of a tightening screw 23. , 5 is a cap body which is attached to the entire surface of the main body 1 except the bottom surface.

A horizontal hole 6 is bored in the lower part of the main body 1, one end of which opens to the outside at one of the overhanging pieces 3, and the other end of which is closed approximately at the center of the other overhanging piece 4. A cut groove 7 is provided at the top of the closed-head cylinder 2 in a direction perpendicular to the direction of the horizontal hole 6.

On the other hand, the cap body 5 has the closed-head cylinder body 2a and the overhang pieces 3a, 4a, which are attached to the closed-head cylinder body 2 and the overhang pieces 3, 4 of the main body 1, opened at the bottom and communicated with each other. The closed-head cylindrical body 2 is formed into a hollow shape.
In a, a slit-shaped window hole 10 large enough to insert a screwdriver, etc. is provided at the top of the front and rear walls 9, 9 on the lower surface of the top plate 8, and V-shaped cuts are made at desired locations on the front and rear walls 9, 9. A groove 11 is provided vertically.
Further, a notch 12 is provided at a lower portion of the outer end of one of the projecting pieces 3a at a position facing the horizontal hole 6. Furthermore, each of the overhanging pieces 3a, 4a is made extremely thin as a whole, and is connected to the front and rear side walls 13a, 13b, and 14a, 14a, respectively.
4b, which are located symmetrically to each other, are formed so as to protrude outward from the other. For example, in FIG.
The projecting piece part 3 is assembled into the main body 1 by protruding 13b outward from 14b.
4, spaces S1 and S2 are formed between them. A plurality of inverted V-shaped notches 15 are provided at the lower edges of the overhanging pieces 3a, 4a.

After all, this cap body 5 is thin as a whole, and each window hole 10, each cut groove 11, each notch 15, and the spaces S1 and S2 formed between it and the main body 1 are weak points. It is designed to be easily damaged by shocks applied during fraudulent activities.

Then, the cap body 5 of the main body 1 is attached, and the two are integrated by heat fusion to form the sealing device A. 16 is a locking pin that is pushed into the horizontal hole 6.

Next, the use of the sealing device A of the present invention constructed as described above will be explained. In FIGS. 7 and 8, 17 is an instrument box, and 18 is an opening/closing lid of the instrument box 17. A screw retainer 19 is fixed inside the instrument box 17, and the opening/closing lid 18
A screw insertion hole 21 is formed opposite the screw hole 20 of the screw holder 19, and a part of the opening/closing lid 18 is cut and raised to form a protruding insertion portion 22 for the sealing string. . Reference numeral 23 denotes a tightening screw to be tightened to the screw holder 19, and the head thereof is passed through a horizontal hole 24 communicating with the horizontal hole 6.

Then, as shown in FIG. 8, the closed-head cylindrical body 2 of the main body 1 is attached to the head of the tightening screw 23 that has been tightened, and the lower surface of the overhanging pieces 3 and 4 is placed on the surface of the opening/closing lid 18.
