Description

[Detailed description of the invention] [Field of industrial application] The present invention covers the sealing screw that screws and fixes the closed part of the opening/closing lid to prevent the interior of the electricity meter, etc. from being opened, thereby preventing fraudulent activities. This article relates to improvements in sealing devices that prevent this.

[Conventional technology]

Conventionally, this type of sealing tool includes a closed-head cylinder which is attached to a sealing screw having a horizontal hole through the head, and a projecting piece connected to the side surface of the closed-head cylinder, and a horizontal hole extending across the closed-head cylinder. A main body into which a sealing pin is press-fitted is combined with a cap body which is attached to the main body, and the cap body is heat-sealed and integrated, and one sealing pin is press-fitted into each horizontal hole in a skewer shape. The applicant has filed an application for a device constructed as follows in Utility Model Application No. 61-2839 (Utility Model Application No. 116279/1983).

[Problem that the invention attempts to solve]

The sealing device related to the above-mentioned Utility Model Application No. 61-2839 is a device in which a sealing pin is formed to have the same length as the horizontal hole and is press-fitted into the horizontal hole. There was a problem that if even a small amount of the protruding part was protruding outward, the seal could be broken by pinching the protruding part with pliers and pulling it out, allowing fraudulent activity to be carried out successfully without destroying the sealing device. .

[Means to solve the problem]

Two sealing pins are used, which are split into lengths that roughly divide the length of the horizontal hole in half.The sealing pins are configured so that they are press-fitted into the horizontal hole in sequence, and the sealing pin that was press-fitted first is used for sealing. Penetrate the horizontal hole of the screw and seal it.

[Effect]

During use, even if the tip of the sealing pin protrudes from the side hole and is pinched with pliers and pulled out, only the sealing pin that was press-fitted later will be pulled out, and the sealing pin that was press-fitted first will be pulled out. The sealing screw remains in the deep part of the horizontal hole, and the sealing device continues to function. Therefore, the seal cannot be released unless the sealing device is destroyed and the sealing pin is removed, which prevents fraudulent activity. It will never be successful.

〔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 body 2 which is attached to the head of a sealing screw 18, and 5 is a main body formed into an oblong shape. It is a cap body that covers the entire surface except the bottom surface.

A horizontal hole 6 is bored in the lower part of the main body, and the side hole 6 is opened at one end to the outside at one of the projecting pieces 3 and the other end is closed at approximately the center of the other side projecting piece 4. A cut groove 7 is provided at the top of the head cylinder body 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 2a and the overhang pieces 3a, 4a which are attached to the closed-head cylinder 2 and overhang pieces 3, 4 of the main body 1 open at the bottom and communicate with each other. It is formed into a hollow shape and further includes a closed-head cylinder body 2a.
A recess is provided at the top of the projecting piece portions 3a, 4a, and a step portion is provided around the middle of the inner wall of the overhanging piece portions 3a, 4a to provide thinner portions 8, 9, respectively.
Further, a vertical cut groove 1 is provided on the outer wall of the closed-head cylinder body 2a.
0 and 10 are provided to form thin parts 11 and 11, and these thin parts 8, 9 and 11 form weak points. Furthermore, one overhang piece 3
A notch 12 is provided at the lower part of the outer end of a at a position facing the horizontal hole 6.

Then, the cap body 5 is attached to the main body 1, and the two are integrated by heat fusion to form the sealing device A.

Reference numerals 13a and 13b are two sealing pins formed to have a length that bisects the length of 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. 4 and 5, 14 is an instrument box, and 15 is an opening/closing lid of the instrument box 14. A screw retainer 16 is fixed inside the instrument box 14, and the opening/closing lid 15 is fixed.
An insertion hole 17 is formed opposite the screw hole 16a of the screw holder 16. 18 is a screw fastener 16
This is a sealing screw that is tightened by the screw, and has a horizontal hole 19 passing through the head which communicates with the horizontal hole 6.

Then, as shown in FIG. 5, the closed-head cylindrical body 2 of the main body 1 is attached to the head of the tightened sealing screw 18, and the lower surface of the overhanging pieces 3 and 4 is attached to the surface of the opening/closing lid 15. If the sealing pin 13a is first press-fitted into the horizontal hole 6 while the sealing pin 13a is pressed into the horizontal hole 6, and then the sealing pin 13b is press-fitted into the horizontal hole 6, the sealing pin 13a that was press-fitted first will be pushed by this sealing pin 13b and the sealing pin 13a that was press-fitted first will be inserted into the horizontal hole. 6 and penetrates the horizontal hole 19 of the sealing screw 18, and its tip reaches the inner end of the horizontal hole 6 to complete the seal.

Note that the seal A is attached to the instrument box 1 as shown in Figure 4.
When attached to the opening/closing lid 15 of 4, the overhanging pieces 3, 4
One or both of them are formed in such a length that they are blocked by the rising wall 20 of the instrument box 14, so that they cannot rotate.

The sealing device A installed in this way completely hides the head of the sealing screw 18 and has a complex external shape, making it difficult to commit fraudulent acts. In this case, a slight impact will cause cracks in the thin parts 8, 9, 11, etc., making it clear that fraud cannot be carried out successfully without breaking the seal A.

If the tip of the sealing pin 13b protrudes even slightly due to some impetus, even if the protruding portion is pinched with pliers and the sealing pin 13b is pulled out, the sealing pin 13a that was previously press-fitted will still remain in the horizontal hole 6. It remains unremovable as it penetrates the horizontal hole 19 of the sealing screw 18 at the back, maintaining the sealed state, and unless the sealing device A is destroyed, fraudulent activity will not be successful.

On the other hand, when sealing device A is destroyed, such as when replacing a meter, or when a resident moves out and the contract has been canceled, a new tenant comes in and renews the meter reading. , by breaking the cut groove 10 provided in the cap body 5 with a screwdriver, and further inserting the screwdriver into the cut groove 7 of the main body 1 and prying it, the sealing screw 18 can be easily extracted and the opening/closing lid 15 can be opened. I can do it.

Note that the technical idea of sequentially press-fitting a sealing pin formed into two parts into a horizontal hole according to the present invention is not limited to the sealing tool having the shape illustrated and explained above, but also applies to a type of sealing pin press-fitted into a horizontal hole. If so, it can be applied to sealing tools of various shapes.

[Effect of idea]

As described above, in the sealing tool of the present invention, the sealing pin that is press-fitted into the horizontal hole and penetrated by the sealing screw is formed with a length that approximately bisects the horizontal hole, and the two pins are press-fitted into the horizontal hole in sequence. Therefore, even if the sealing pin that was press-fitted later is pulled out, the sealing pin that was press-fitted first will remain stuck in the sealing screw at the back of the horizontal hole and remain unremovable, maintaining the sealed state and preventing the sealing device from being removed. You cannot successfully commit fraud unless you corrupt the .
