Detailed Description

As shown in figure 1, the portable telescopic student bookshelf comprises a bookshelf body capable of being stretched and lengthened, wherein a book fixing and clamping assembly is arranged on the front side of the bookshelf body capable of being stretched and lengthened, and a foldable supporting assembly is arranged on the rear side of the bookshelf body capable of being stretched and lengthened.

As shown in fig. 1, fig. 3, fig. 5 and fig. 6, the bookshelf body capable of stretching to be long comprises an upper supporting plate 4 and a lower supporting plate 2, wherein an upper sliding groove 1 is arranged on the upper side of the upper supporting plate 4, a lower sliding groove 5 is arranged on the lower side of the upper supporting plate 4, a lower supporting plate 2 is arranged on the lower portion of the upper supporting plate 4, and the upper side and the lower side of the lower supporting plate 2 are respectively installed in the upper sliding groove 1 and the lower sliding groove 5 in a matching manner.

As shown in fig. 1 and 3, the book fixing clip assembly includes a left fixing clip 6 and a right fixing clip 3, the left fixing clip 6 is fixedly installed on the upper support plate 4, and the right fixing clip 3 is fixedly installed on the lower support plate 2.

As shown in fig. 3 and 7, the left fixing clip 6 and the right fixing clip 3 have the same structure, the right fixing clip 3 includes a fixing plate 34, the fixing plate 34 is fixedly mounted on the lower support plate 2, a mounting tube 32 is disposed on one side of the fixing plate 34, an O-shaped clamping rod 33 is disposed on the fixing plate 34, and the O-shaped clamping rod 33 is cooperatively mounted on the mounting tube 32 through a torsion spring 31.

As shown in fig. 2, 4, 5 and 6, the foldable support assembly includes a left supporting vertical plate 8 and a right supporting vertical plate 7, the left supporting vertical plate 8 is hinged to the rear side of the lower support plate 2, and the right supporting vertical plate 7 is hinged to the rear side of the upper support plate 4.

The utility model discloses when using, according to the length size of the books that use, backup pad 4 and bottom suspension fagging 2 are pulled out to both sides in the hand-held, open the books after place the utility model discloses on, the O shape clamping bar that pulls up left fixation clamp 6 utilizes torsion spring's elasticity to press from both sides the left half of books tightly, and the O shape clamping bar 33 that pulls up right fixation clamp 3 again utilizes torsion spring 31's elasticity to press from both sides the right half of books tightly, and at last, opens left side support riser 8 and right side support riser 7 respectively, makes the utility model discloses can place on the desktop, make things convenient for the student to read.
