Abstract

The utility model relates to a bookcase, which is a telescopic bookcase or a bookcase wider when extending and narrower when retracting. The bookcase is composed of a left case body, and a right case body and middle case body, wherein the three case bodies are in cuttage grafting. The transverse slats in the left and the right case bodies are of groove-tenon structure or of tenon-groove structure. The transverse slat of the middle case body capable of extending and retracting is of groove-tenon structure or of tenon-groove structure and is matched with the tenons and the grooves in the left and the right case bodies in cuttage grafting. The utility model has the advantages that: firstly the adjustability of the width of the bookcase is realized, the user can adjust the width of the bookcase according to the collection of books, the wider the width is, the more collection of books is, and the narrower the width is, the less collection of books is, and the width of the bookcase can be adjusted according to the width of room; further, the utility model has the advantage of novel, unique, simple and practical structure design.

Description

retractable bookcase

technical field

The utility model relates to a bookcase that can be stretched out to make it wider, retracted to make it narrower or telescopic, and belongs to the field of bookcase manufacturing.

Background technique

CN2824680Y, titled "Multi-purpose combined cabinet metal frame structure", the structure is composed of special-shaped metal pillars, metal clapboard connection scales, connecting fixed baffles, supporting feet, combination screws, connecting plates, cabinet bodies, and clapboards. Its shortcoming: this bookcase does not have the function of telescopic, poor adaptability.

Contents of the invention

Design purpose: To avoid the shortcomings in the background technology, to design a retractable bookcase that not only has a telescopic function, but also can adjust the width of the bookcase according to the amount of books and the width of the place.

Design scheme: In order to achieve the above design purpose. The utility model divides the bookcase into three parts on the basis of the existing bookcase (to be precise, on the existing bookshelf). The left and right ends of the top board, bottom board, and shelf in the cabinet body are all staggered tenon and tenon structures, while (1) the right ends of the top board, bottom board, and shelf in the left cabinet body are all interlaced tenon and tenon structures. Groove structure and match with the staggered tongue-and-groove structure or groove-tenon structure of the left end of the top board, bottom board and shelf in the middle cabinet, and the left cabinet can be extended or retracted; (2) the top board, bottom board, The left ends of the shelves are all staggered tenon-groove structures or tenon-and-groove structures, and are plugged and matched with the staggered tenon-and-groove structures or tenon-groove structures on the top plate, bottom plate, and right end of the shelf in the middle cabinet, and the left cabinet body can be extended or retracted. Back, thereby realizing the design purpose of the present utility model. Its technical solution: retractable bookcase, the bookcase is composed of the left cabinet body, the right cabinet body and the middle cabinet body. The groove structure or the groove and tenon structure are respectively matched with the groove and tenon in the left and right cabinets and can be extended or retracted.

Compared with the background technology, the utility model realizes the adjustability of the width of the bookcase, so that users can adjust the width of the bookcase according to the amount of books they have collected. The wider the width, the more books are collected; The volume is less, and the width of the bookcase can also be adjusted according to the width of the room; second, the structural design is novel, unique, simple and practical.

Detailed ways

Embodiment 1: with reference to accompanying drawing 1 and 2. Telescopic bookcase, the bookcase is composed of the left cabinet 7, the right cabinet 8 and the middle cabinet, the horizontal board 1 in the left and right cabinets is a groove 2, tenon 3 structure, the middle cabinet horizontal board 6 is tenon 4, groove 5 The structure is matched with the groove 2 and tenon 3 in the left and right cabinets respectively and can be extended or retracted. The groove is a dovetail groove, the tenon is a dovetail tenon and matches the dovetail groove, and the horizontal plate 6 Including the top plate, shelf, bottom plate and the tenon surfaces at the left and right ends of the middle cabinet horizontal plate 6, there are separate support plates 7 and 8 in the perpendicular direction. The role of supporting and separating the height of the book shelf.

Embodiment 2: On the basis of Embodiment 1, the horizontal plate 1 in the left and right cabinets has a structure of tenon 3 and groove 2, and the horizontal plate 6 of the middle cabinet body has a structure of groove 5 and tenon 4 and is respectively connected with the tenons in the left and right cabinets. 3. Slot 2 is mated and can be extended or retracted
