Description

Technical Field

[0001] The invention relates to the field of stationery tools, and in particular to a paperweight-type split bookcase. Background Art

[0002] Traditional bookshelves are too bulky, take up a large space on the desktop, and lack functionality. They can only be used to store books and tablets, but not as paperweights. They have uneven bottoms, are not heavy enough, and take up space. The function of a paperweight is even more limited, and can only be used as a weight to press on the surface of an object to level it. This application combines these two products to invent a paperweight-type split bookshelf, which solves the problem that the bookshelf takes up too much desktop space and is inconvenient to carry, and also solves the problem that the paperweight has a single functionality. In view of the above problems, a paperweight-type split bookshelf is proposed. Summary of the invention

[0003] Aiming at the shortcomings of existing products, the present invention proposes a paperweight-type split book shelf to solve the above problems.

[0004] The present invention aims to solve the problems of materials, structures and usage of bookshelves and paperweights.

[0005] As an improvement of the above technical solution, the paperweight-type split book shelf uses alloy material as the main body and steel, copper, etc. as auxiliary materials. It can not only strengthen the structure and increase its own weight to a certain extent, but also be durable, easy to clean and carry.

[0006] As an improvement of the above technical solution, the paperweight-type split book shelf is divided into two parts through structural design, consisting of an L-shaped base with adjustable angle and a rotatable and foldable cross-shaped bracket. When unfolded, the two parts can be combined into a book shelf; when folded, they can become two independent paperweights; when combined, they can be stored into a paperweight-type rectangular block; it is flexible to use and easy to operate, meeting the various needs of users.

[0007] As an improvement of the above technical solution, the paperweight-type split-type bookcase has a variety of practical tools embedded in the structure; the pen is fixed by the central axis of the rotatable and foldable cross-shaped bracket and the vertical limit groove on the edge of the rotation and positioning expansion plate, so that the product has the same principle of compass function; the 270-degree annular hollow groove around the central axis and three screw columns arranged in an equilateral triangle are used, and a scale is printed around the edge of the groove, so that the product has the function of a protractor. A circular glass cover with a bubble inside is provided on the central hollow circle of the rotation and positioning expansion plate, which can be used as a level; the strength support rod is removed separately, and the scale on the scale support rod is used as a ruler.

[0008] As an improvement of the above technical solution, the paperweight-type split bookcase has additional functions such as a protractor, a compass, a level and a ruler, all of which are designed through a unique layout of the structural parts themselves and integrated into the product as a whole.

[0009] As an improvement of the above technical solution, when the paperweight-type split bookcase is used in conjunction with items on a desktop or tabletop with supporting legs, such as photo frames, drawing boards, electronic tablets with protective covers, etc., the L-shaped base can be used alone as an important component of the bookcase.

[0010] As an improvement on the above technical solution, when the paperweight-type split bookcase is used as a paperweight, the first part and the second part are separated and placed on both sides of the unrolled paper or scroll, so as to quickly and conveniently flatten the paper and serve as two paperweights.

[0011] The beneficial effect of the present invention is that the paperweight-type split bookcase uses alloy materials and takes advantage of the hardness, easy processing, and fine finished product of metal materials, thereby increasing the accuracy of the product and giving it more practical functions, making it compact and easy to carry.

[0012] The paperweight-type split book shelf has multiple practical functions, and is equipped with a paperweight, a book shelf, a protractor, a level, a compass, and a ruler, so as to meet the multiple needs of users for daily study and make storage easier.

[0013] The paperweight-type split book shelf achieves the stability of the product's rotation angle and the convenience of various combinations through magnetic attraction between components and locking of positioning beads with component grooves, reduces the steps of switching between various functions, and facilitates user operation.

[0014] The paperweight-type split book shelf can be used in combination with common products, such as photo frames, drawing boards, electronic tablets with protective covers, etc. It is convenient for users to use the product's book shelf function while using other additional functions at the same time, thereby increasing the practicality of the product.

[0015] The paperweight-type split book shelf can not only realize the function of a paperweight through a split structure, but also serve two purposes, that is, it enhances the use function of the paperweight and increases the practicality of the product.

[0016] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
