Description

[Detailed explanation of the idea] <Industrial application field> The present invention relates to a packaging structure for a kerosene stove.

<Prior art> Conventionally, in order to pack a kerosene heater, as shown in Figures 5 to 6a and 6b, a cardboard box with a required height is formed in advance into a cylindrical shape, and the mating portions are formed into a cylindrical shape. The fixing tool 1a is constructed by closing with packing tape 11 or the like, and after loosening and removing the screws 12, 12 of the top plate 8 of the kerosene stove 10, the fixing tool 1a is attached to the upper end stage of the combustion tube 6a. Part 7a
Then, after leaving the top plate 8 still, it is screwed on with screws 12, 12, so that the combustion tube, which is the most mobile and unstable during transportation, is not shaken by the fixing device 1a. We are trying to maintain stable conditions.

<Problems to be solved by the invention> However, in the conventional example described above, the top plate 8 must be attached and detached when inserting and removing the fixture 1a each time, such as when packaging on a packaging line or when conducting a combustion test. The operation is extremely complicated, which is one of the factors that impairs work efficiency.

Therefore, the present invention aims to address the problems associated with the above-mentioned conventional examples and provide a fixture with good workability.

<Means for solving the problem> In Figures 1 to 3, the shaft part 2 is located at the center of the top surface.
a base member 1 having a spiral guide portion 3 on its periphery and a spiral guide portion 3 on its periphery; The combustion tube is packed using a fixture A consisting of a mating member 5.

<Function> Fixture A inserted between the upper end of the combustion cylinder and the top plate
By rotating the fitting member 5 relative to the base member 1, the height of the fixture A becomes higher,
It is placed between the top plate and the top of the combustion tube.

<Example> Fig. 1 shows a fixture A of the present invention, in which reference numeral 1 denotes a base member having a cylindrical shaft portion 2 protruding from the center of the upper surface as shown in Fig. 2; The guide portion 3 has a spiral shape. A step portion 4 is formed between the ends of this guide portion 3 .

Reference numeral 5 denotes a ring-shaped fitting member which is detachably and rotatably inserted into the shaft portion 2, and as shown in FIG. A stepped abutting portion 7 is formed between the ends of the tapered portion.

When this fitting member 5 is fitted onto the shaft portion 2 and the stepped portion 4 and the contact portion 7 are aligned as shown in FIG. 1, a cylindrical fixture is obtained.

When the fitting member 5 is rotated in the direction of the arrow, the tapered portion 6 slides on the guide portion 3, and the fitting member 5
The upper surface 5a of is vertically raised. Both the fitting member 5 and the base member 1 are made of polystyrene foam, and since there is a strong force between the respective joint surfaces, the fitting member 5 will not fall down even if the upper surface 5a is pressed. In short, the height between the top and bottom of the fixture can be freely adjusted by rotating the fitting member 5.

Next, examples of packaging will be explained with reference to FIGS. 4a, b, and c. First, the fixture is inserted into the stepped portion 7 of the combustion tube 6 from the front of the kerosene stove 10. In this state, the fourth
As shown in FIG. 4B, when the fitting member 5 is rotated in the direction of the arrow, the upper surface 5a of the fitting member 5 rises and finally comes into contact with the lower surface of the top plate 3 as shown in FIG. 4C. Then, when the fitting member 5 is further rotated, the upper surface 5a comes into pressure contact with the lower surface of the top plate, and the combustion tube 6 is fixed to the top plate 8 via the fixture. Therefore,
Even if a small amount of vibration is applied, the combustion cylinder will not wobble or fall, and will be held stably.

On the other hand, when removing fixture A, all you have to do is rotate the fitting member 5 in the opposite direction to lower the height of the fixture.
It is also easy to remove.

<Effects of the invention> The present invention is constructed as described above, and by using the fixing device of the present invention, it is possible to attach and detach the fixing device without removing the top plate of the stove each time on the packaging line or during a combustion test. This is a device with high practical value, as it requires less time and significantly improves workability, and since it is a fixing device with a simple structure, it does not require any special skill and can be easily handled by any person.
