Multilayer detachable arch-shaped book storage rack for library

Abstract

The invention provides a multilayer detachable arch-shaped book storage rack for a library, belongs to the technical field of book storage racks. The problem that although universal wheels with brakedevices are installed at bottom of existing book storage rack, when book storage rack is used in fixed state, if brake is treaded only, whole book storage rack cannot be stabilized, and then stabilityof book storage rack in use is reduced is solved. The arch-shaped book storage rack comprises a rack body, and two first arch-shaped supporting plates and two second arch-shaped supporting plates areinstalled in the rack body. The book storage rack is moved to a proper position through universal wheels at the bottom of the rack body, and then a lifting screw rod is rotated, so that a threaded cylinder drives a lifting plate to move downwards under the action of threads, the four supporting columns move downwards, when the bottom end faces of the four supporting columns make contact with theground, the universal wheels at the bottom of the bookshelf body are separated from the ground, the bookshelf is stably supported, and the stability of the bookshelf in the using process is improved.
