Description

Crossbeam-hidden type desktop book supporting frame

Technical Field

The utility model relates to a prop bookshelf technical field, specifically speaking, in particular to hidden desktop of crossbeam props bookshelf.

Background

In order to improve the comfort of people, particularly young students, during reading, maintain health and protect eyesight and cervical vertebra, applicants invented various desktop book supports. These desktop book supports have two states of opening and folding, and the types include folding type, turnover type and the like. These desktop support bookshelves are all from opening the book board that props, and the not enough that exists lies in:

1) not only the structure is comparatively complicated, the assembly difficulty, and the cost is higher, and the preceding back size and the transverse dimension of propping the bookshelf are great moreover, can lead to the desktop fluting area big to influence the holistic aesthetic property of desktop.

2) The desktop book supporting frame is limited by the structure, the desktop is arranged at a front position, so that a writing area on the desktop can be occupied when the desktop book supporting frame is used, the groove in the desktop is open, and articles such as learning tools and the like can easily fall into the groove.

3) After the book is supported, the height of the book is not high enough relative to the desktop, so that the depression angle during reading is large, and the book needs to be read with the head down.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a hidden desktop of crossbeam props bookshelf.

The technical scheme of the utility model is that: the utility model provides a hidden desktop of crossbeam props bookshelf, includes desktop and double-layered book device, its characterized in that: a groove is formed in the rear end of the desktop; the book clamping device is characterized by further comprising a lifting mechanism, wherein a fixed part of the lifting mechanism is arranged on a desktop or in a groove, a movable part of the lifting mechanism can move up and down in the groove, a cross beam is arranged at the top end of the movable part of the lifting mechanism, and a left book clamping device and a right book clamping device are arranged on the cross beam side by side.

The utility model discloses a crossbeam replaces the book board that props among the background art, and the structure is simpler, assembles more easily, can effectively provide assembly efficiency, reduction in production cost.

The lifting mechanism consists of a sliding seat and a sliding strip, the sliding seat is fixed on the rear groove wall of the groove or the bottom of the desktop, a sliding groove is formed in the sliding strip, and the sliding strip is in sliding fit with the sliding seat through the sliding groove.
