Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a wire drawing device, and more specifically, to a wire drawing device that is easy to transport and store.

“Prior Art and Problems” Conventionally, line drawing tools for drawing lines on stadiums, etc., have a powder discharge part 3 equipped with a powder discharge hole 2 at the bottom of a cylindrical container 1, as shown in FIG. It is equipped with wheels 4 and 4' on both sides, an opening 5 and a foldable lid 6 at the top, and a handle 7 attached to the side of the container 1. After putting powder such as calcium carbonate into the container 1, close the lid 6, hold the handle 7 and move it forward in a predetermined direction.
Powder is discharged from the powder discharge hole 2 to perform wire drawing.

However, although the conventional wire drawing tool has a lid, it is not a closed type. This is to simplify the structure and to use the gap between the opening and the lid as an air hole to prevent the inside of the container from becoming depressurized. Therefore, if the container is tipped on its side, the powder spills out of the container, making it inconvenient to transport and store.For example, even if the container is transported in the trunk of a car, the trunk gets dirty and it is extremely difficult to transport it without such contamination. be. Furthermore, slaked lime has excellent hygroscopicity,
When it absorbs moisture, it becomes lumpy and hinders the wire drawing work, but since conventional wire drawing tools are not airtight, the remaining powder must be transferred to another airtight container after use, which is extremely troublesome. . Further, such transfer does not only pollute the environment, but also increases the chances of the product entering the eyes or trachea of the worker or adhering to the hands and feet of the worker, which is not good for health.

"Means for Solving the Problems" In view of the above-mentioned problems, the present invention was devised as a result of intensive research to eliminate the above-mentioned drawbacks.

That is, the present invention provides a wire drawing device comprising a powder discharge part with a powder discharge hole at the bottom of a cylindrical container, wheels on both sides, an opening and a lid at the top, and a handle. , the opening is made to protrude into a cylindrical shape to form a lid attachment part, a male screw or a female screw is carved into the lid attachment part, a through hole is bored, and the lid attachment part is screwed. The lid body has a female screw or a male screw carved therein and a through hole bored therein, and when the lid body is tightened, both through holes do not communicate and maintain a sealed state, and when the lid body is loosened, both through holes overlap. The drawing device is characterized in that it has a structure in which the wires communicate with each other to form an air vent hole.

There is no particular restriction on the material used for the cylindrical container of the present invention, and plastic, paper, wood, metal, glass, etc. can be used. Further, the shape of the container is not particularly limited, and examples thereof include a cylindrical shape, a rectangular tube shape, and the like.

``Example'' An embodiment of the present invention will be described based on the drawings. FIG. 2 is a perspective view of the wire drawing device of the present invention, and FIG. 3 is an enlarged exploded view of the main parts.

In these figures, the wire drawing device of the present invention is
Wheels 14, 14' are provided on both sides of a powder discharge part 13 having a powder discharge hole 12 at the bottom of the cylindrical container 11,
The upper part is provided with a cylindrically protruding lid mounting part 15 and an opening 16 at its tip, and the lid mounting part 15 is provided with a male or female thread and a through hole 17. has been done. On the other hand, the lid 18 is provided with a female thread or a male thread for screwing into the lid mounting portion 15, and a through hole 19 is formed therein.

The relationship between the through hole 19 of the lid body 18 and the through hole 17 of the lid body attachment part 15 is such that when the lid body 18 is tightened onto the lid body attachment part 15, the through holes 19 and 17 are moderately shifted. There is no communication between the holes 1 and 1, which is in a sealed state.On the other hand, when the lid 18 is loosened appropriately, both through holes
9 and 17 are in a positional relationship such that they overlap and communicate with each other to form an air hole. Therefore, in order to facilitate the overlapping of the two through holes 19 and 17, it is preferable that the through holes have a horizontally elongated shape, an elliptical shape, or the like. Furthermore, by providing a locking mechanism to maintain the state in which both the through holes 19 and 17 overlap to form a ventilation hole, it is possible to prevent both through holes from shifting and closing due to vibration during the wire drawing operation.
This is a favorable condition.

Handle receivers 20, 2 are provided on both sides of the cylindrical container 11.
0', and a handle 22 with fixed rings 21, 21' loosely inserted therein is rotatably attached to the handle receivers 20, 20' via pins 23, 23'. When the fixed rings 21, 21' are moved to positions covering the pins 23, 23', the handle 22 is fixed in an upright position, and the fixed rings 21, 21' are moved above the pins 23, 23'. Then, the handle 22 can be bent around the pins 23, 23'.

The wire drawing device of the present invention configured as described above has the following features:
Unscrew the lid 18 and pour the powder into the container 1 through the opening 16.
After filling the inside, the lid is tightened to a position where the through hole 19 of the lid 18 and the through hole 17 of the lid mounting portion 15 overlap. If a lock mechanism is provided, turn on the lock at this time. Next, the fixed rings 21, 21' are moved to a position covering the pins 23, 23', and the handle 2
2 is fixed in an upright position and used for wire drawing work.

When the wire drawing work is completed, the lid body 18 is tightened. At the same time, the through hole 19 of the lid body 18 and the lid attachment part 15
It is shifted by an appropriate distance from the through hole 17 to form a substantially sealed state. After that, if necessary, the fixed ring 21,
21' is moved upward and the handle 22 is folded to make a compact shape for storage or transportation.

"Operation/Effect" As mentioned above, according to the present invention, the opening can be sealed, so even if the powder falls on its side during drawing work, storage, or transportation, the powder will not spill out and contaminate the surrounding area. There's nothing to do,
It is easy to store and transport, and since the remaining powder can be virtually sealed after use, there is no need to transfer it to another sealed container, which saves labor.
It has many advantages, such as reducing the chances of direct contact with hands and feet, and reducing the chances of it being dispersed into the surrounding area, which is beneficial for environmental preservation and health.
