[Industrial applications]

The present invention relates to a structure of a sealing cover that covers a printer to reduce noise during printing or to prevent dust from entering.

For example, a wire dot printer or the like generates considerable noise during printing.

 Further, if dust adheres, a trouble such as a failure occurs.

To cope with these, the printer is covered with a sealing cover.

Further improvement in the sealing performance is required for these sealing covers.

[Conventional technology]

As shown in the side view of FIG. 2 (a), one or more operation covers are provided on the airtight cover 1 for accommodating the printer 12 for operations such as setting paper to the printer 12 and taking out printed paper. Hole 2 is unavoidably provided.

These holes 2 are covered with a cover plate 3 because they pose a problem in soundproofing and dustproofing when they are left as they are, and are opened as shown by a two-dot chain line only when necessary.

That is, as shown in the main part plan view of FIG. 2B and the partially enlarged side view of FIG. 2C, the cover plate 3 is hinged about the hinge 4 so as to be rotatable as indicated by arrows AB. , So as to cover the entire hole 2.

In the drawing, reference numeral 5 denotes a stopper for preventing a gap around the cover body 1a and the cover plate 3 and for supporting and stabilizing the cover plate 3 as shown in FIG. It protrudes from 1a along the three sides of the hole 2.

[Problems to be solved by the invention]

In the above configuration, the stopper 5 cannot be provided on the side provided with the hinge 4 in order to smoothly rotate the cover plate 3 around the hinge 4.

Therefore, it can be provided only at the three ends of the cover plate 3, and a gap is formed at the end provided with the hinge 4.

There has been a problem that noise leaks from the gap or dust enters, thereby lowering the hermeticity.

 The purpose of the present invention is to improve the sealing performance.

[Means for solving the problem]

In order to achieve the above object, in the present invention, as shown in a partially enlarged side view of FIG.
A cover plate 7 rotatably provided on the cover main body 1a by a support shaft 6 and engaged with the hole 2 of the cover main body 1a to open and close it.
And a side 2a of the hole 2 parallel to and close to the support shaft 6.
An elastic member 9 provided on the back surface over the entire length of the hole 2 and three sides 2b other than the side 2a of the hole 2 apart from the support shaft 6.
The stopper 5 is provided over substantially the entire length of the cover plate 7 and comes into contact with three peripheral surfaces of the cover plate 7 when the cover plate 7 rotates so as to close the hole 2, and the elastic member 9 of the cover plate 7 Over the entire length of the end portion 7a opposed thereto, and also presses the elastic member 9 when the cover plate 7 is turned to close.
10, and when the lid plate 7 is rotated to open, the edge of the lid plate 7 presses against the longitudinal end of the stopper 5 to regulate the opening angle of the lid plate 7. It was done as follows.

[Action]

When the lid plate is turned around the support shaft so as to close the hole,
The overhanging portion of the cover plate also rotates, and the surface presses the surface of the elastic member of the cover body.

As a result, the part where a gap has been formed in the prior art is sealed.

〔Example〕

 FIG. 1 shows an embodiment of the present invention.

 The same parts are denoted by the same reference numerals throughout the drawings.

As shown in the partially enlarged side view of FIG. 1 (a), the sealing cover 11 in the present invention has a cover body 1a and a cover body 1a.
A cover plate 7 rotatably provided by the support shaft 6 and engaging with and closing the hole 2 of the cover body 1a; and the total length of the side 2a of the hole 2 parallel to and close to the support shaft 6. The elastic member 9 provided on the back surface is provided along the substantially entire length of the three sides 2b other than the side 2a of the hole 2 apart from the support shaft 6, and
When the cover plate 7 is rotated to close the hole 2, the cover plate 7
The stopper 5 protrudes from the cover main body 1a into the hole 2 and the end 7a of the cover plate 7 facing the elastic member 9 and protrudes along the entire length of the cover plate 7 so that the three peripheral edges abut. Hole 2
And an overhanging portion 10 for pressing the elastic member 9 when it is turned to close.

That is, the elastic member 9 is, for example, maltprene and is provided on the cover main body 1a by bonding.

On the other hand, as shown in a partial perspective view of FIG. 2B, the overhang portion 10 is composed of upper and lower metal fittings 10a and 10b provided so as to sandwich the cover plate 7, and an end of the upper metal fitting 10a. Is formed in a Z shape with a step, and the lower metal fitting 10b is a flat plate, and is formed between the end of the lid plate 7 by a tongue piece 10b 'bent upward from both ends. The support shaft 6 is formed so as to be clamped and fixed.

The portions where the ends of both metal fittings 10a and 10b are in contact are integrated into a tongue shape by, for example, welding.

According to such a configuration, when the cover plate 7 is rotated around the support shaft 6 so as to close the hole 2, as shown in a partially enlarged side view of FIG. Also rotates.

Then, the surface of the elastic member 9 of the cover main body 1a is pressed by the surface of the overhang portion 10.

With this, the portion where the gap is generated in the conventional technique is sealed, and the sealing performance of the sealing cover 11 is improved.

Also, unlike the hinge of the prior art, the length of the stopper 5 provided on both sides of the cover body 1a is changed as shown in FIG. The angle can be set arbitrarily.

Further, as shown in the plan view of FIG. 2D, unlike the prior art (FIG. 2B), since an external hinge is not required, the effect of improving the aesthetic appearance is also achieved.

[Effect of the invention]

According to the present invention, the sealing performance is improved, and the dustproofing and soundproofing effects are improved.
