Description

Technical Field

[0001] The utility model belongs to the technical field of periodical display equipment, in particular to a periodical display rack with adjustable height. Background Art

[0002] Periodical display racks are used to place and display periodicals, magazines and other publications. They are one of the indispensable equipment in places such as libraries and reading rooms.

[0003] In order to satisfy readers' reading and study needs, libraries or reading rooms will display various categories of periodicals. These different categories of periodicals are usually of different sizes. However, the height of the partitions of existing periodical display racks is fixed. When encountering large-format periodicals, it will be difficult to put the periodicals in or out, which brings inconvenience to readers. In addition, when large-format periodicals are stored and retrieved, the cover, spine and page corners of the periodicals will be squeezed, causing the periodicals to be folded and worn, affecting the integrity and service life of the periodicals and also causing losses to the library. When encountering small-format periodicals, the internal height space of the display rack is wasted, reducing the number of periodicals that can be placed on the display rack. Utility Model Content

[0010] Furthermore, a second shaft hole is provided on the operating rod, and a second shaft rod matched with the second shaft hole is provided on the clamping block.

[0011] Furthermore, the gear bin is provided with a protective cover, the upper and lower surfaces of the protective cover are respectively provided with limit sliders, the top and bottom of the gear bin are respectively provided with limit slide grooves for matching the limit sliders, the outer facade array of the protective cover is provided with several anti-slip strips, and a linear slide groove adapted to the hollow circular tube is provided on the protective cover.

[0012] Furthermore, three shaft rods are relatively fixedly provided on the vertical surfaces on both sides of the back plate, and three shaft holes matching the three shaft rods are respectively provided on the inner vertical surfaces on both sides of the cabinet body. Slot holes are respectively provided on the vertical surfaces on both sides of the back plate, and a spring is fixedly connected to the inner vertical surfaces of the slot holes. A limit plate is fixedly connected to the top of the spring, and a limit clamp matching the limit plate is fixedly provided at the opening of the slot hole.

[0017] When in use, the operating dial is turned to make the gear meshing rack move up and down, thereby driving the top cover to move up and down, so that the height inside the display cabinet can be freely adjusted to accommodate journals of different sizes. This solves the problem of insufficient internal space height of the display cabinet for journals with large formats, which makes it inconvenient to take and put journals, avoids damage to the cover and spine and wear of the folded corners of the footers caused by squeezing of the journals, extends the service life of the journals, and reduces the economic cost of the library. When encountering journals with small formats, the height of the top cover is lowered, thereby lowering the height of the display cabinet. Each display cabinet is independent, and lowering the height can increase the number of stacking and the number of journals that can be stored on the journal display rack. Moreover, when adjusting the height of the display cabinet at the bottom, it does not affect the internal space height of the display cabinet above, thereby increasing the flexibility of the journal display rack.
