Description

[Detailed explanation of the invention] This invention was developed for automobiles, especially taxi odometers, electricity,
Related to bundle seals for gas, water, etc. meters, bus fare boxes, etc.

For example, as a sealing tool that makes sealing work easy,
There is one described in Publication No. 5-27389.

This sealing tool consists of a sealing wire and a sealing wire fixing body that is provided with a sealing wire pull-out prevention spring inside which is formed with a sealing wire fixing hole and has a locking part that locks the sealing wire. The blocking spring allows the sealing wire to be inserted in the direction in which the sealing wire is inserted into the sealing wire fixing hole, but in the direction in which the sealing wire is pulled out, the tip of the spring is prevented by the elastic force of the spring. It is designed to lock the seal wire, and after inserting the seal wire into the horizontal hole in the bolt head of the meter lid tightening bolt and the sealing hole in the meter lid, insert it into the seal wire fixing hole. It shall be sealed.

Incidentally, after sealing a meter or the like, a mark indicating that the measurement has been completed or verified may be engraved on the sealing wire fixing body using a sealing punch.

When stamping with a sealing punch like this, it is necessary to make sure that the tip of the sealing punch does not get stuck on the meter etc.
The sealing wire is slackened to provide an appropriate distance between the sealing wire fixing body and the meter, etc.

However, in the above-mentioned sealing device, if the sealing wire is slack after sealing, pinch the slack part of the sealing wire with your fingers and insert the sealing wire into the sealing wire fixing hole and from this fixing hole. If the seal wire is pulled while reciprocating in small increments in the direction in which the seal wire is pulled out, the seal wire may fall out of the seal wire fixing hole, and there is a risk that the seal may be illegally released.

This invention was made in view of the above-mentioned circumstances, and provides a sealing device with a binding body that can be engraved on the seal line fixed body of the sealing device with a sealing punch after sealing, and can prevent unauthorized release of the seal. It is something.

The sealing device with a bundling body according to this invention includes a sealing wire fixing body which has a sealing wire and a sealing wire fixing hole formed therein, and a sealing wire pulling-out prevention spring that extends into the fixing hole, and a sealing wire fixing body that extends from the sealing wire fixing body. The binding body is provided with a sealing wire insertion hole for folding and inserting the sealing wire.

Hereinafter, embodiments of this invention will be described in detail with reference to the drawings.

1 to 6 show a first embodiment of this invention, in which a sealing device with a bundle 1 is composed of a seal wire fixing body 2, a seal wire 3, and a bundle 4.

The sealing wire fixing body 2 consists of a front half body 10, a back half body 2o, and a leaf spring 30 for preventing the sealing wire from being pulled out.

The front half 10, the back half 20, and the seal line 3 are made of synthetic resin such as ABS resin by integrally forming the bottom shape at the same time.

The front half 10 has a substantially truncated conical shape, and the surface with a larger outer diameter serves as a joint surface 11 and the surface with a smaller outer diameter serves as a display surface 12.

Two engaging protrusions 13 are provided on this joint surface 11, and two seal wire fixing grooves 14a, 14b and a leaf spring fitting groove 15 communicating with these fixing grooves 14a, 14b are formed, respectively. ing.

The seal wire fixing grooves 14a, 14b are formed parallel to both sides of the joint surface 11, have a rectangular cross section, and are slightly larger than half the cross section of the seal wire.

The leaf spring fitting groove 15 is approximately S-shaped, and the central inclined portion 1
6 and two both end inclined portions 17, the width of both end inclined portions 17 gradually increases toward the sealing wire fixing grooves 14a, 14b, and communicates with the sealing wire fixing grooves 14a, 14b. .

Both inclined surfaces of the both end inclined portions 17 are indicated by 17a and 17b.

The back half 20 also has a substantially truncated conical shape, with a surface with a larger outer diameter serving as a joint surface 21 and a surface with a smaller outer diameter serving as a display surface 22.

Then, on the joint surface 21, there are two engaging protrusion fitting recesses 23.2.
The two seal line fixing grooves 24a, 24b and the leaf spring fitting groove 25 communicating with these fixing grooves 24a, 24b are connected to the engagement protrusion 13 of the front half 10 and the seal line fixing grooves 14a, 14b.
and is formed at a position corresponding to the leaf spring fitting groove 15.

The reason why the seal line fixing grooves are formed in both the front half 10 and the back half 20 is to reduce the thickness of both halves.

The inner diameter of the engaging protrusion fitting recess 23 is approximately equal to the outer diameter of the retaining protrusion 13.

Further, the leaf spring fitting groove 25 is the leaf spring fitting groove 15 of the front half body 10.
Similarly, it is approximately S-shaped and consists of a central inclined portion 26 and two end inclined portions 27.

Both inclined surfaces of the both end inclined portions 27 are indicated by 27a and 27b.

The front half body 10 and the back half body 20 are connected to each other in a flexible manner at a part of their joint surfaces 11.21.

This connection is indicated by A. Leaf spring 3 for preventing the seal wire from being pulled out
0 is approximately S-shaped and consists of a fixing part 31 fitted into the central inclined part 16.26 of the leaf spring fitting groove 15.25, and locking parts 32 housed in both end inclined parts 17.27.

The leading ends of the locking portions 32 project into the seal line fixing grooves 24a*24b, respectively.

This leaf spring 30 can be made, for example, by bending a band-shaped metal plate.

The sealing line 3 is integrally formed on the back half body 20.

The seal line 3 is attached to two seal line fixing grooves 24a, 24.
It extends in the opposite direction to the connecting part A from the position between b.

After fitting the leaf spring 30 into the leaf spring fitting groove 25 of the back half body 20, the seal wire fixing body 2 connects the front half body 10 and the back half body 20 at their connecting portion A at both joining surfaces 11.21. It is assembled by bending the engaging protrusion 13 in the direction in which they touch each other, fitting the engaging protrusion 13 into the engaging protrusion fitting recess 23, and welding the tip of the engaging protrusion 13 and the edge of the joint surface 11.21.

This state is shown by the chain line in FIG.

Of course, only the edges of the joint surfaces 11.21 may be welded.

As shown in FIG. 3, the bundle 4 has a rectangular parallelepiped shape and is made of synthetic resin such as ABS.

The bundle 4 can be made of metal or hard rubber in addition to synthetic resin.

Also, the shape is not limited to a rectangular parallelepiped.

It can be any shape such as an elliptical plate or a cube.

A sealing wire insertion hole 33 is formed in the bundle 4 through the center thereof.

The cross-sectional shape of the insertion hole 33 is rectangular, and its size is slightly larger than twice the cross-section of the sealing wire 3.

Next, the sealing operation will be explained.

Referring to FIGS. 4 and 6, first, the seal wire 3 protruding from the seal wire fixing body 2 is inserted into the seal wire insertion hole 33 of the bundling body, and then the meter 5 to be sealed is tightened and fixed. Insert the sealing wire 3 into the horizontal hole drilled in the head of the lid tightening bolt 6 and the sealing hole 7 formed in the lid of the meter 5, and then insert the sealing wire 3 into the sealing wire insertion hole 33 of the bundle 4 again. Insert the sealing wire 3 in the opposite direction to the direction in which it was inserted.

Then, the seal wire 3 is inserted into one fixing hole 34A of the seal wire fixing holes 34A, 34B formed by the opposing seal wire fixing grooves 14at 24at 14b, 24b of the front half 10 and the back half 20, and then This fixing hole 34A
The seal wire 3 is inserted into the other fixing hole 34B in the opposite direction to the direction in which it was inserted, and the tip of the seal wire 3 is pulled so that there is no slack between the seal wire fixing body 2 and the meter 5.

In the direction in which the seal wire 3 is inserted, both locking portions 32 of the leaf spring 30 are bent inward to allow the seal wire 3 to pass through, but in the direction in which the seal wire 3 is pulled out, the leaf spring 30 Due to the elastic force of 30, the tip of the locking portion 32 is wedged into the sealing wire 3 made of synthetic resin.

Once sealed, even if you try to pull out the seal line 3, the tip of the locking part 32 of the leaf spring 30 will not touch the seal line 3.
Seal line 3 cannot be pulled out because it is wedged deeper.

Even if an attempt is made to forcefully pull out the sealing wire 3, the locking portion 32 hits the inclined surface 17ay27a, so that the tip of the locking portion 32 remains embedded in the sealing wire 3.

Finally, the sealing wire 3 is cut from the location where the tip of the locking portion 32 is bitten.

Therefore, it cannot be restored.

If the seal line 3 is cut in this way, it means that the meter has been tampered with.

Furthermore, since the seal line 3 is tightly pulled and sealed, it is impossible to pull the seal line 3 out by moving the seal line 3 back and forth in small increments.

Furthermore, since the bundle 4 is attached to the seal wire 3 between the seal wire fixing body 2 and the meter 5, the tip of the seal punch can be attached to the meter 5 when marking the seal wire fixing body 2 with a seal punch. do not have.

7 and 8 show a second embodiment of this invention, in which the plate spring fitting grooves 15, 25 of the seal wire fixing body 2 and the plate spring 3
