Description

Piano stool

Technical Field

The utility model belongs to piano annex field, in particular to see a low-cost, environmental protection, durable piano bench.

Background

The existing piano stool legs are mostly wooden. Because of the particularity of the actual use and the durability of impact stress, the piano stool has more noble and superior wood used for the stool legs. But the wood also inevitably causes the problems of cracking, paint explosion, worm damage, rottenness and the like of the stool legs, and seriously threatens the normal use and the service life of the piano stool. Particularly, the rare and special high-quality wood has the advantages of short supply of goods, high price, high cost and few felling resources.

In the prior art, the stool legs of the piano stool are usually made of solid wood, and the piano baking finish process is carried out on the solid wood stool legs to prepare the finished stool legs.

The Chinese patent application: 201911174779.8, title of the invention: piano-like baking varnish furniture part and production method thereof and piano

A music stool; it discloses an imitation piano baking finish furniture part, including plastic casing and filler, between the filler, filler and plastic casing all combine as an organic whole through glue, and the filler be wood granule or wood powder, find in the actual course of working that the glue in the middle part of furniture part can't solidify or the solidification is incomplete, the reason is as follows: the two ends of the furniture part communicated with the outside are certainly cured firstly, a sealed space is formed in the middle of the furniture part after curing, and the glue cannot be cured or cured completely in the sealed space, so that an area with weak structural strength is formed in the middle of the furniture part and cannot meet the actual use requirements of people.

Disclosure of Invention

To the problem that prior art exists, the utility model designs a piano stool that structural strength is reliable, low in production cost, environmental protection and durable.

The technical proposal of the utility model is as follows;

a piano stool comprises

The stool legs are arranged in four corners;

the coamings are arranged between the adjacent stool legs and are fixedly connected with the stool legs through steel connecting pieces;

bench face, bench face assembly on the top surface of bench leg and bounding wall, its characterized in that:

the stool legs comprise a hollow outer shell formed by injection molding and an inner stool body formed by processing solid wood, the inner stool body is embedded in the outer shell, and the outer shell completely covers the surface of the inner stool body.

Furthermore, the outer shell and the inner stool body are connected together in a tight fit mode.

Further, the bounding wall including the hollow bounding wall casing that forms of moulding plastics to and the bounding wall body that forms by the wood processing, the embedding of bounding wall body is installed in hollow bounding wall casing.

Further, the lower limb indent of the side surface of bounding wall casing be formed with the mounting groove, processing has the step of stepping down the mounting groove on the bounding wall body, still include with the layer board of the mounting groove gomphosis of bounding wall all around, layer board and bounding wall and bench face form a storage space.

Furthermore, the outer shell and the coaming shell are formed by injection molding of plastic particles of at least two colors.

Furthermore, the surfaces of the outer shell and the coaming shell are provided with appearance surface layers through in-mold transfer printing processing.

Furthermore, the surfaces of the outer shell and the enclosing plate shell are covered with UV paint surface layers.

Further, the wall thickness of the outer shell and the coaming shell is 1-2 mm.

To sum up, the utility model discloses following beneficial effect has:

the utility model discloses utilize the shell body to carry out the cladding to the internal bench body, and link together through the mode of close-fitting between shell body and the internal bench body, firstly, the shell body that plastics were made has certain plasticity, is difficult for forming the damage on the surface in the use, has guaranteed the aesthetic measure after the piano bench uses for a long time, secondly, the shell body that plastics were made can protect the internal bench body, the internal bench body that the wood was made is difficult to appear the problem of fracture, worm eaten or rotten; moreover, the outer shell and the inner stool body are tightly matched, extra glue is not used, no volatile gas is generated, and the environment-friendly effect is better.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, a piano stool comprises stool legs 1 and four stool legs which are arranged in four corners; the coamings 2 are arranged between the adjacent stool legs and are fixedly connected with the stool legs through steel connecting pieces; stool face 3, the stool face assembly is on the top surface of stool leg and bounding wall, stool leg 1 is including the hollow shell body 10 that forms of moulding plastics to and the interior stool body 11 that forms by the wood processing, interior stool body 11 embedding is installed in shell body 10 and the surface of the interior stool body of shell body complete cladding.

The utility model improves the stool legs, the inner stool body made of solid wood is embedded and installed in the outer shell, and the two are assembled into a reliable and stable whole and are not easy to fall off under the condition of general external force; the shell body can form more pleasing to the eye outward appearance face at injection moulding in-process, need not extra paint or post-treatment such as color, has reduced the production step, has improved production efficiency, has also reduced the gaseous pollutant that probably introduces among the post-treatment process, and the feature of environmental protection obtains guaranteeing, and in addition, interior bench body is made for the wood, has better structural strength, satisfies people's user demand.
