Description

Technical Field

[0001] This utility model belongs to the field of fixed bookshelf technology, specifically, it relates to a space expansion structure for a fixed bookshelf. Background Technology

[0002] With the development of the knowledge economy and the improvement of people's cultural literacy, the number of books, documents, and various collectibles is constantly increasing. Bookshelves, as important storage tools, are widely used in homes, schools, libraries, offices, and other places. Among them, fixed bookshelves, with their advantages of stable structure, strong load-bearing capacity, and long service life, have become the choice of many users.

[0003] However, some existing fixed bookshelves often expand the original bookshelf space by adding telescopic panels to the original bookshelf. Therefore, when the panels are pulled out, although books can be placed on them, the lack of supporting components on the panels makes them prone to deformation due to gravity.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To address the problem that some existing fixed bookshelves often expand the original shelf space by adding telescopic panels, which, while allowing books to be placed on top, are prone to deformation under gravity due to the lack of supporting components, the basic concept of this utility model is as follows:

[0006] A space expansion structure for a fixed bookshelf includes a bookshelf frame. The inner cavity of the bookshelf frame is provided with multiple bookshelf partitions arranged at equal intervals. Each bookshelf partition has an extension frame on its front side. The sidewall of the bookshelf frame has multiple rectangular slots arranged at equal intervals. Each extension frame has a baffle at its end away from the bookshelf partition. The baffle has two symmetrical positioning blocks at its end near the bookshelf partition. Each positioning block has a movable rod between each pair of blocks, and the other end of each movable rod is located within a rectangular slot.

[0007] In a preferred embodiment of this utility model, each of the baffles has a handle groove on the side wall away from the bookshelf partition.

[0008] In a preferred embodiment of this utility model, each rectangular slot has two combined slots in its inner cavity, and each combined slot is symmetrical to the other. Each combined slot has a sliding slider slidably disposed in its inner cavity, and each sliding slider is symmetrical to the other.

[0009] In a preferred embodiment of this utility model, each of the movable sliders is provided with a movable rod on one of its opposite side walls.

[0010] In a preferred embodiment of this utility model, each of the movable rods is arranged in a triangular configuration between each other and between each other and the baffle.

[0011] In a preferred embodiment of this utility model, each of the extension frames is inserted into the bookshelf partition.

[0012] In a preferred embodiment of this utility model, the combined groove is composed of a straight sliding groove, a lifting groove, and a locking groove.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This invention allows the movable rod to move by moving the baffle. With the assistance of the combination groove and the movable slider, the movable rod can change its angle, thus ensuring that the expanded extension frame and the movable rod form a triangle. This ensures good stability when books are placed on the extension frame and avoids deformation and bending to a certain extent.

[0015] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0024] like Figures 1 to 5 As shown, a space expansion structure for a fixed bookshelf includes a bookshelf frame 1. The inner cavity of the bookshelf frame 1 has multiple equidistantly distributed bookshelf partitions 2. Each bookshelf partition 2 has an extension frame 3 on its front side. The sidewalls of the bookshelf frame 1 have multiple equidistantly distributed rectangular slots 6. Each extension frame 3 has a baffle 4 at its end away from the bookshelf partition 2. At the end of the baffle 4 near the bookshelf partition 2, there are two symmetrically positioned blocks 11. A movable rod 10 is positioned between each pair of positioning blocks 11. The other end of each movable rod 10 is located within a rectangular slot 6. The movement of the baffle 4 moves the movable rod 10, allowing the movable rod 10 to change angle with the assistance of the combination slot 8 and the movable slider 9. This ensures that the expanded extension frame 3 and the movable rod 10 form a triangle, thus guaranteeing good stability when books are placed on the extension frame 3 and preventing deformation and bending to a certain extent.

[0025] In a specific embodiment, each baffle 4 has a handle slot 5 on the side wall away from the bookshelf partition 2. In this configuration, the location of the handle slot 5 is determined.

[0026] Furthermore, each rectangular slot 6 has two combined slots 8 inside its cavity, with each pair of combined slots 8 being symmetrical to the others. Each combined slot 8 also has a sliding slider 9 slidably mounted inside its cavity, with each pair of sliding sliders 9 being symmetrical to the others. In this configuration, the positions of the sliding sliders 9 and the overall positions of the combined slots 8 are determined.

[0027] Furthermore, each movable slider 9 has a movable rod 10 on one of its opposite side walls. The position of the movable rod 10 is determined in this configuration.

[0028] Furthermore, each movable rod 10 is arranged in a triangular configuration with each other and with respect to the baffle 4. In this configuration, the shape formed between the movable rod 10 and the baffle 4 is determined.

[0029] Furthermore, each extension frame 3 is inserted into the bookshelf partition 2. In this setup, the connection relationship between the extension frame 3 and the bookshelf partition 2 is defined.

[0030] Furthermore, the combined groove 8 consists of a linear slide groove 81, a lifting groove 82, and a locking groove 83. In this configuration, the composition of the combined groove 8 is determined.

[0031] The implementation principle of the space expansion structure of a fixed bookshelf in this embodiment is as follows:

[0032] Firstly, when staff need to expand the space within the bookshelf frame 1, they can pull the handle slot 5 on the baffle 4 located on the front side of the bookshelf partition 2. This allows the baffle 4 to pull the extension frame 3 out of the bookshelf partition 2, thus expanding the space. Simultaneously, when the baffle 4 is pulled out, the angle can be changed by the movable rod 10 with the assistance of the combination groove 8 and the movable slider 9. This ensures that the expanded extension frame 3 forms a triangle with the movable rod 10 (initially, the movable rod 10 pulls the movable slider 9 horizontally along the straight slide groove 81). At this time, the movable rod 10 and the baffle 4 form a triangle, but the angle between the movable rod 10 and the baffle 4 is small, resulting in poor stability. However, when the movable slider 9 moves onto the lifting groove 82, the angle between the movable rod 10 and the baffle 4 increases, thereby improving stability. When the movable slider 9 enters the slot 83, the slot 83 can limit the movable slider 9, thereby further ensuring the stability between the movable rod 10 and the baffle 4. Therefore, the extension frame 3 has good stability when placing books, and to a certain extent, it avoids deformation and bending.
