An adaptive multifunctional book end

Abstract

The invention provides a self-adaptive multifunctional book stand comprising a bottom plate a, telescopic rods, a telescopic sleeve rod, a bottom plate b and movable plates. The bottom plate a is arranged on one side of the bottom plate b; a baffle plate a is connected to the joint portion between the top surface of the bottom plate a and a tongue plate and a baffle plate b is connected to the joint portion between the top surface of the bottom plate b and a tongue plate; the baffle plate a is a hollow cuboid with the top surface provided with a first notch, wherein a telescopic plate a is arranged in the first notch; an upper top plate a is connected to the top end of the telescopic plate a; the two ends of the telescopic rods are connected to the telescopic plate a and a telescopic plate b via connectors a and connectors b; the telescopic sleeve rod is sleeved with a plurality of sleeves and each sleeve is connected to one end of the corresponding movable plate; thus the utilization rate of space on a desk is increased; the baffle plate b is provided with main control box which matches an optoelectronic switch, photoconductive resistor sheets and voltage-dependent resistor sheets, so that the book stand can achieve self-adaptive automatic clamping.

Description

technical field [0001] The invention relates to the technical field of student supplies, in particular to an adaptive type multifunctional book stand. Background technique [0002] As we all know, contemporary students have a lot of pressure to study, heavy schoolwork, and many books. Putting books in the bookshelf can greatly reduce the occupation of space and improve the utilization rate of space. At present, most of the book stands in the stationery market are made of metal or non-metal at one time. The bottom plate of the book stand and the vertical plate are perpendicular to each other, and the book is placed in the middle of the two book stands when in use. This kind of book stand has a simple structure, but it is easy to overturn when there are fewer or more books, and the book stand has fewer functions and insufficient space utilization; sometimes when there are too many books in the book stand, it is not easy to move the two stoppers of the book stand board, and wh...

Problems solved by technology

This kind of book end has a simple structure, but it is easy to fall when there are few or many books, and the book end has less functions and insufficient space utilization; sometimes when there are too many books in the book end, it is difficult to move the two stoppers of the book end board, and when picking up the book, it may cause the book to tilt or require us to clamp the book end, which is time-consuming and laborious, so we need to design a new book end to improve space utilization and have multiple functions.
