The L-shaped bookshelf has a support plate and a bottom plate perpendicular to the support plate, and the support plate A through groove perpendicular to the bottom plate is opened in the middle of the surface, fixing clips are respectively arranged on both sides of the through groove, and the fixing clips are located close to the bottom plate.

Preferably, at least three wheels are provided on the bottom of the base, and one of them is a universal wheel.

Preferably, the length adjusting pole includes a first pole and a second pole, the lower end of the first pole is fixedly connected to the base, and the upper end is screwed to the lower end of the second pole.

Preferably, a threaded rod is fixed on the outer circumference of the lower end of the angle adjusting rod, and a threaded hole matching the threaded rod is provided on the upper end of the second rod, and the threaded rod is screwed into the threaded hole , connecting the angle adjustment pole with the second pole.

Preferably, iron wires are arranged transversely on the upper part of the support plate, and the fixing clip is passed through the iron wires and can slide along the iron wires.

Preferably, the utility model further includes a top plate opposite to the bottom plate, the top plate is fixedly connected to the support plate, and a light strip is arranged on the lower part of the top plate.

The economics teaching frame of the utility model can not only avoid the problem of muscle soreness caused by long-term hand-held textbooks, but also prevent the textbooks from slipping when placing the textbooks, and has high flexibility; The stand has a lighting function.

detailed description

The specific embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific embodiments.

An economics teaching frame, as specifically shown in Figure 1-2, includes a base 100, a length adjustment pole, an angle adjustment pole 200 and an L-shaped bookshelf, the lower end of the length adjustment pole is connected to the upper part of the base 100 The lower end of the angle adjustment pole 200 is rotatably connected to the length adjustment pole, and the upper end is fixedly connected to the bottom of the L-shaped bookshelf. The L-shaped bookshelf has a support plate 300 and The support plate 300 is perpendicular to the bottom plate 400, the middle part of the upper surface of the support plate 300 is provided with a through groove 301 perpendicular to the bottom plate 400, and the two sides of the through groove 301 are respectively provided with fixing clips 302, and the The fixing clip 302 is located close to the bottom plate 400 .

The length adjusting pole includes a first pole 201 and a second pole 202, the lower end of the first pole 201 is affixed to the upper part of the base 100, and the upper end is screwed to the lower end of the second pole 202. catch.

The outer periphery of the lower end of the angle adjustment pole 200 is vertically fixed with a threaded rod 203, and the upper end of the second pole 202 is provided with a threaded hole matching the threaded rod 203, and the threaded rod 203 is screwed to the In the threaded hole, the angle adjusting rod 200 is connected with the second rod 202 .

An iron wire 303 is arranged transversely on the upper part of the support plate 300 , and the fixing clip 302 is passed through the iron wire 303 and can slide along the iron wire 303 .

When the economics teaching rack of the utility model is used, the back of the book is embedded in the through groove 301. After the textbook is opened, the position of the textbook is fixed by the fixing clip 302, which prevents the textbook from slipping from the bookshelf, and the fixing clip 302 can hold the pages of the book. It avoids the phenomenon that the pages of the book are automatically turned randomly, so that teachers can concentrate on writing on the blackboard, avoiding the problem of muscle soreness caused by holding the textbook for a long time. In addition, the length adjustment rod can adjust the height of the teaching shelf, and the angle adjustment rod 200 can adjust the angle of the bookshelf, so that the utility model can adjust the height and angle according to the needs of different people, and has high flexibility. .
