ことにより封印し得る封印具をも得たのである。 Among them, the inventor of the present invention claimed that it was the first patented invention in 1973.
As disclosed in No. 42697, the leaf spring ring with a locking claw constituting the sealing device is housed inside the housing, and can be handled as a single unit without fear of losing the parts. Furthermore, after sealing, a built-in leaf spring ring with claws can be engaged with the sealing screw head to achieve the intended purpose. In addition, Jikko 57
As disclosed in No. 5642, the synthetic resin sleeve has a locking step on the inner circumferential surface and is open at the bottom, and the upper half can be freely expanded and contracted by cutting grooves. The locking part is provided in such a manner that the lower half has a notch part for receiving the head of the sealing machine screw, and the small hole of the head of the sealing machine screw is inserted at right angles to the notch part. By combining the locking piece with a protruding pin that can be inserted into the sealing device, a sealing tool that can be sealed by inserting the pin into the hole in the head of the sealing machine screw and pushing down the sleeve was also obtained.

い。 However, in the former case, the locking pawl of the leaf spring ring that locks the head of the small sealing screw for sealing after the seal is broken sticks to the screw head and does not come off easily. This was inconvenient for subsequent handling. In the latter case, if there is a large gap between the sealing screw and the adjacent protruding wall (for example, the side surface of the instrument panel cover) after the sealing device is installed, There is a risk that the sealing screw may be loosened by rotating the sleeve of the sealing tool, and the seal may be broken. This will not give you a complete sealing effect.

いられる。 A locking piece 1 that fits into such a sleeve 1
0 has a cylindrical upper half 11 and has two locking steps 12' and 13' on the outer periphery of the tip and is locked by locking fins 12 and 13 that are inclined toward the tip. A groove 14 is formed by the fins 12 and 13, and a locking step 15' is provided by protruding a locking fin 15 from the locking steps 12' and 13' at a position closer to the middle of the dimension as appropriate. has a diameter larger than that of the upper half 11, and a notch 17 is provided on one side from the center as shown in FIG. ) A pin 19 that engages with the hole 42 of the head 41 is implanted. A rotation preventing protrusion 18 is provided at a position opposite to this notch 17. This locking piece 10 is integrally molded from synthetic resin or easily molded metal.

封印効果を発揮する。 The sleeve 1, the locking leaf spring ring 8, and the locking piece 10 configured in this way are such that when not in use, the locking pawl 8' of the leaf spring ring 8 locks. The pieces 10 are engaged with the grooves 14 at their ends and are assembled together in a state where they cannot be removed. When in use, the pin 19 is inserted into the small hole 42 of the head 41 so that the head 41 of the small sealing screw 40 is received in the notch 17 of the locking piece 10, and the pin 19 is inserted into the small hole 42 of the head 41. The opening part of the main body covers the head 41 of the sealing machine screw 40. If the sleeve 1 is pushed down as it is, the locking pawl 8' will be angled upward and fitted into the groove 14 of the locking piece 10, so it will be pushed against the elastic force by the locking fin 13 directly below it. The upper half 11 of the locking piece 10 deeply enters the inside of the housing 1, climbs over the locking fin 15 at the intermediate position, and engages the locking step 15' and the locking pawl 8'. When these are engaged, the sealing machine screw head 41 is confined within the housing 1 as shown in FIG. 3, and the protrusion 18 is also accommodated within the rotation stopper 3.
Since the rotation stoppers 3 and 4 of the housing 1 are unable to rotate due to contact with the case side wall A' of the instrument A (see Fig. 4), the sealing machine screw can no longer be used unless the sealing device is destroyed. 40 can no longer be rotated,
Demonstrates a sealing effect.

ない。 If the sealing tool is intentionally rotated after this sealing, either the rotation stopper part 3 or 4 of the housing 1 will come into contact with the case side wall A' of the instrument A, and the sealing machine screw 40 will be loosened. When the rotation stopper part 4, which is formed in a rectangular cylinder shape, has a weaker structure than the rotation stopper part 3 on the opposite side, when it is rotated by applying an excessive external force, this part breaks. Since it is in an irreversible state, even if you try to reseal it, it will no longer be possible. Therefore, the seal cannot be broken.

An example of this is shown in FIGS. 5 and 6, in which the locking piece 20 is made of a synthetic resin having elasticity and appropriate hardness, such as polyethylene, and the upper half 21 is made into a truncated conical shape with a locking fin 23 of an appropriate thickness at the top, and a cylindrical groove with an appropriate width and a cylindrical shape in the middle. An annular groove 24 is carved with a depth such that the root diameter is smaller than the diameter of the insertion hole 9 formed by the locking step portion 5' (provided on the sleeve 1A), and a lower half portion 25 is continuous with the annular groove 24.
has a structure similar to that of the specific example described above. Identical parts are given the same reference numerals.

It is assembled without coming off. And when sealing, by pushing down the mantle 1A,
The upper half 21 of the locking piece 20 is compressed by the cut groove 22, the locking step 5' engages with the annular groove 24, and the protrusion 18 fits inside the rotation stopper 3 to form a seal. (See Figure 7).
