Detailed Description

In order to make the technical solutions and advantages of the embodiments of the present utility model more apparent, the following detailed description of exemplary embodiments of the present utility model is provided in conjunction with the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present utility model and not exhaustive of all embodiments. It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other.

Embodiment one:

The embodiment takes a teacher as an example for explanation, and the portable bookshelf comprises a bottom frame 1 and a bracket 2, wherein the bottom frame 1 and the bracket 2 are of a structure with one end open and one end blocked, and the open end of the bottom frame 1 is rotationally connected with the open end of the bracket 2;

A mounting rod 201 and a stop rod 202 are respectively arranged between two sides in the opening end of the bracket 2, the stop rod 202 is positioned above the mounting rod 201, a spring 2011 is sleeved on the mounting rod 201, and a support plate 3 is sleeved outside the spring 2011.

In the specific implementation process, as shown in fig. 1-4, the underframe 1 and the support 2 are both in a U-shaped structure, the support 2 is rotatably connected in the underframe 1, the open end of the support 2 is provided with at least one spring clip 4, in this embodiment, the number of the spring clips 4 is two, the two spring clips 4 are all installed between two upright posts 203, a cross bar 103 is arranged between the open ends of the underframe 1, and the cross bar 103 is in a U-shaped structure and is mainly used for facilitating handholding; a threaded hole 101 is formed in the opening end of the underframe 1, a bolt 102 is screwed in the threaded hole 101, a rotating hole is formed in the opening end of the bracket 2, and the end part of the bolt 102 extends into the rotating hole. In operation, a teacher can carry the bookshelf to a classroom through the cross rod 103, then unfold the underframe 1 and the support 2, the blocking ends of the underframe 1 and the support 2 are all placed on a platform, finally the bottom end of a book is placed on the support plate 3, the book is supported by utilizing the acting force of the spring 2011, and the stop lever 202 can support and block the top end or the outer side of the book to prevent the book from turning on one's side while supporting the book; after the use, the underframe 1 and the bracket 2 are folded, and then the bracket 2 can be positioned by manually twisting the two bolts 102.
