Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example one

Referring to fig. 1-4, a book showing stand for a library comprises a case body 1, wherein an upper grid 3 and a lower grid 2 are arranged on the case body 1, the lower grid 2 and the upper grid 3 are respectively used for placing books, the books in the upper grid 3 are difficult to take and place due to the fact that the upper grid 3 is higher in height, and a power mechanism is arranged between the upper grid 3 and the lower grid 2 and can drive the upper grid 3 to move to be aligned with the lower grid 2 in height; the power mechanism comprises a telescopic cylinder barrel 6 and a telescopic cylinder rod 7; the telescopic cylinder rod 7 is sleeved on the telescopic cylinder barrel 6, and the tail end of the telescopic cylinder rod 7 is rotatably arranged on the side edge of the upper-layer grating 3; the tail end of the telescopic cylinder barrel 6 is hinged to the side edge of the box body 1; and then when the telescopic cylinder barrel 6 further drives the movement of the upper grid 3 when rotating, because the telescopic cylinder barrel 6 is sleeved with the telescopic cylinder barrel 7, and further when the telescopic cylinder barrel 6 rotates, the upper grid 3 firstly moves along the upper surface of the box body 1 and then moves along the side surface of the box body 1, so that the upper grid 3 is further aligned with the lower grid 2 in height, and further great convenience is brought to people to take books.

Furthermore, in order to improve the actual use effect of the device and enable the movement track of the upper grid 3 to be more accurate, a limit groove 10 is formed in the side wall of the box body 1, a roller 9 is slidably mounted in the limit groove 10, a connecting rod 8 is fixedly mounted on a rotating shaft of the roller 9, and the other end of the connecting rod 8 is fixedly connected to the upper grid 3; when the telescopic cylinder barrel 6 drives the upper grid 3 to move in a rotating mode, the upper grid 3 always ensures that the movement track is consistent with the shape of the limiting groove 10 through the arrangement of the connecting rod 8 and the idler wheel 9 with the limiting groove 10.
