The technical problem to be solved by the utility model is to provide a simple multifunctional triangular standing bookshelf which is simple in structure, small in volume, convenient and quick to assemble, foldable and free to expand and contract, and suitable for different book sizes. the

The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a simple multifunctional triangular standing bookshelf, which includes two symmetrically arranged triangular retaining frames, and the triangular retaining frames include triangular triangular support steel pipes, two a transition support steel pipe and two base support steel pipes, the two ends of the lower end of the triangular support steel pipe are respectively inserted into the transition support steel pipe, the lower end of the transition support steel pipe is supported by the base through a bolt knob Steel pipe activity connection. the

The angle of the triangular support steel pipe is 40 degrees. the

The two ends of the lower end of the triangular support steel pipe are respectively longitudinally and evenly distributed with several first through holes, and the upper end of the transition support steel pipe is provided with a plurality of second through holes used in conjunction with the first through holes. holes, and the first through hole is fixedly connected to the second through hole through a bolt. the

The free end of the base support steel pipe is provided with an extension steel pipe, and the extension steel pipe is inserted into the base support steel pipe. the

A plurality of third through holes are evenly distributed in the horizontal direction on the extended steel pipe, and a plurality of fourth through holes used in conjunction with the third through holes are arranged on the base support steel pipe. The hole is fixedly connected with the fourth through hole through a bolt. the

The two triangular support steel pipes are integrally connected by connecting steel bars. the

The triangular support steel pipe is provided with a clamping groove, and the ends of the connecting steel bars are clamped and embedded in the clamping groove. the

Compared with the prior art, the utility model has the advantages that: the utility model is a simple multifunctional triangular vertical bookshelf, which includes two symmetrically arranged triangular retaining frames. The triangular retaining frames include triangular triangular support steel pipes, two A transition support steel pipe and two base support steel pipes, the two ends of the lower end of the triangular support steel pipe are respectively inserted into the transition support steel pipe, and the lower end of the transition support steel pipe is flexibly connected with the base support steel pipe through a bolt knob. Books can be placed in the middle of the two tripods, and the number of books to be supported can be controlled by adjusting the distance between the two tripods, and the angle of the transitional support steel pipe and the base support steel pipe can be adjusted by rotating the bolt knob, so that the books can be adjusted according to a certain Placed at an inclined angle, it has a certain aesthetic effect. It has the advantages of simple structure, small size, convenient and quick assembly, foldable and free telescopic, suitable for books and materials of different sizes, and beautiful in appearance. the

Further, because the angle of the triangular support steel pipe is 40 degrees, the distance between the two base support steel pipes is suitable, which is suitable for placing books. the

Further, because the two ends of the lower end of the triangular support steel pipe are longitudinally evenly distributed with several first through holes, and the upper end of the transition support steel pipe is provided with several second through holes used in conjunction with the first through holes. The second through hole is fixedly connected by a bolt. The connection between the triangular support steel pipe and the transition support steel pipe is more convenient, flexible and firmer, and the adjustment of different heights of the bookshelf is realized through the cooperation of the through holes. the

Further, since the free end of the base support steel pipe is provided with an extension steel pipe, the extension steel pipe is inserted into the base support steel pipe, and several third through holes are evenly distributed horizontally on the extension steel pipe, and the base support steel pipe is provided with Several fourth through holes are used, and the third through hole is fixedly connected with the fourth through hole through a plug. By extending the steel pipe, the distance between the two tripods can be further increased, so that more books can be placed on the base support steel pipe, and the connection between the base support steel pipe and the extended steel pipe is more convenient, flexible and firmer. Cooperate to realize the adjustment of different lengths of extended steel pipes. the

Further, because the two triangular support steel pipes are integrally connected through the connecting steel bars, the triangular support steel pipes are provided with clamping grooves, and the ends of the connecting steel bars are clamped and embedded in the clamping grooves. Books are made more stable by connecting steel bars. the
