Description

[Detailed description of the invention] [Field of industrial application] This invention provides a protective covering for the sealing screw that screws and fixes the closed part of the terminal cover so that it cannot be removed in order to prevent the interior of the electricity meter etc. from being opened. Furthermore, the present invention relates to a sealing tool that can be easily destroyed and removed when the seal is opened for meter inspection replacement, meter inspection renewal, etc.

[Conventional technology]

Conventionally, as this type of sealing device, the applicant filed a patent application in 1983.
-2839 (Utility Model Publication No. 62-116279) was improved and filed on September 12, 1986 with the following structure. The device of this application has a protruding piece connected to the side surface of a closed-head cylinder which is attached to a sealing screw having a horizontal hole penetrated through the head, and a horizontal hole passing through the closed-head cylinder. In a sealing device in which a body into which a sealing pin is press-fitted and a cap body which is attached to the body are combined and integrated by heat fusion, the sealing pin is disassembled into lengths that roughly divide the length of the horizontal hole in half. , these sealing pins are press-fitted in order.

[Problem that the invention attempts to solve]

The sealing device described above can almost achieve the intended purpose of preventing unauthorized acts such as destroying the cap body or pulling out the sealing pin, but for example, it can be When a new tenant moves out and the contract has been canceled, and the meter readings are renewed after a new tenant moves in, sealing devices are surprisingly difficult to destroy and work is difficult. It was hot.

A particular object of the present invention is to provide a sealing tool that can be destroyed and removed quickly and with good workability when replacing or updating a meter.

[Structure of the idea]

In the seal having the above structure, the main body is provided with a concave groove at the lower part of the outer periphery and a cut groove is provided at the top of the closed-head cylinder, and the cap body is formed thin as a whole, and the closed-head cylinder has a groove. A horizontal cut groove is provided in the shoulder portion and the body is attached to the main body, and the lower part is heat-sealed into the groove while being fitted into the groove. The sealing pin is structured to be divided into approximately two lengths and press-fitted into the horizontal holes one after another in the same way as the sealing tool of the application dated September 12, 1985.

[Effect]

The cap body can be easily destroyed by hitting its closed-head cylinder body with a screwdriver or pinching it with pliers, etc., and the main body is exposed. Therefore, if you stick a screwdriver into the top of the closed-head cylinder of the main body and pry it up, the main body will be destroyed, and the sealing pin that was press-fitted into the side hole later can be removed, and the sealing pin that was press-fitted into the side hole first will be sealed. Since it remains through the screw, removing it together with the sealing screw completes the removal of the sealing device. [Example] In the figure, 1 is the outer surface of the closed-head cylinder 2 that is attached to the head of the sealing screw 18. It is a main body in which a projecting piece 3 of a required length and an arc-shaped projecting part 4 are arranged facing each other, and are made of ABS resin or the like. Reference numeral 5 denotes a cap body to be attached to the main body 1, which is made of transparent acrylic resin or the like colored as desired, and has a thin wall thickness as a whole.

The main body 1 is provided with a cut groove 6 in a direction perpendicular to the longitudinal direction of the main body 1 at the top of the closed-head cylinder 2, and is further provided with a cut groove 6 at the bottom of the outer periphery of the closed-head cylinder 2, the overhang piece 3, and the protrusion 4. A groove 7 of a required depth is provided around the circumference, and a horizontal hole 8 is bored from the outer wall of the groove 7 through the overhanging piece 3 and the closed-head cylinder 2 to reach the protrusion 4. Further, a vertical hole 9 is formed in the protrusion 4 so as to face the horizontal hole 8, and a receiving pin 10 is inserted into the vertical hole 9.

On the other hand, the cap body 5 is a closed-head cylinder body 2 which is attached to the closed-head cylinder body 2, the overhanging piece part 3, and the protruding part 4 of the main body 1.
a, the overhang piece 3a and the protrusion 4a are formed into a hollow shape that communicates with each other and is open at the bottom, and the closed-head cylinder 2
A horizontal cut groove 11 is positioned opposite to the shoulder of a.
11, and a notch 12 for keeping the horizontal hole 8 open at the lower part of the outer end of the overhanging piece 3a.

Then, the lower part of the cap body 5 is fitted into the groove 7 of the main body 1, and the lower edge of the cap body 5 is heat-sealed onto the bottom wall of the groove 7, thereby integrating the two to form the sealing device A. do.

Seal pins 13a and 13b are press-fitted into the horizontal hole 8, and are each formed to have a length that bisects the length of the horizontal hole 8. These sealing pins 13a, 13b
One of the sealing pins 13a is inserted into the horizontal hole 8 in advance.
Press it into place.

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 a meter, and 15 is a terminal cover of the meter 14. Instrument 14
A screw holder 16 is fixed therein, and the insertion hole 1 is inserted into the terminal cover 15 so as to face the screw hole 16a of the screw holder 16.
7 have been established. Reference numeral 18 denotes a sealing screw that is fastened to the screw holder 16, and a horizontal hole 19 communicating with the horizontal hole 8 is passed through the head thereof.

Then, as shown in FIG. 5, the closed-head cylindrical body 2 is attached to the head of the tightened sealing screw 18, and the horizontal hole 8 is opened with the bottom surface of the main body 1 aligned with the surface of the terminal cover 15.
If the remaining sealing pin 13b is press-fitted, the sealing pin 13a that was press-fitted first is pushed by the sealing pin 13b and enters the back of the horizontal hole 8, and is inserted into the horizontal hole 1 of the sealing screw 18.
9, and the tip reaches the inner end of the horizontal hole 8 to complete the seal. In addition, the sealing pins 13a, 13b
Even if a force for press-fitting is applied further, it is blocked by the receiving pin 10 and stops.

The seal A installed in this way can be used when a meter is being inspected or replaced, or when a new tenant moves in and the meter reading is changed after a resident has moved out and the contract has been canceled. When removing the seal A as shown in FIG. Broken body 1
Since the closed-head cylindrical body 2 can be exposed, by inserting a screwdriver into the cut groove 6 and prying it up, the main body 1 can be destroyed, the sealing screw 18 can be extracted, and the terminal cover 15 can be opened.

[Effect of idea]

As mentioned above, the sealing device of the present invention can be easily destroyed by prying it with a screwdriver when replacing a meter or renewing a meter reading.
It has advantages in terms of conservation and management.
