Description

Novel book clip

Technical Field

The utility model belongs to the technical field of student's apparatus technique and specifically relates to a novel book end.

Background

The reading rack is an auxiliary learning article for placing books or electronic products, so that the hands of students are liberated, the learning efficiency is improved, the myopia rate is reduced, the existing reading rack with high learning competition pressure has single function, the height and the angle can not be adjusted under the action of supporting the books, and the reading rack is large and poor in stability, so that the improvement is needed.

The night book reading frame with the bulletin number of CN207613414U makes an effort, a lighting environment is provided for students to read books at night through the lamp body, so that the students can learn at night, the learning time of the students is effectively prolonged, the positioning blocks are clamped into the positioning grooves at different positions, the positions of the book plates are adjusted, the positions of the books and the eyes of the students can be adjusted, and the students can select proper positions to place the book plates; the direction is rotated through the pivot on the locating piece to the book board passes through the support and supports, thereby the book board can change inclination, is favorable to the selection of student's reading custom, and the spheroid cooperates with the arc wall on the locating plate, has the advantage that the support is stable, the regulation is convenient. The device is not easy to store and has small height and angle adjusting range, so the device needs to be improved.

Disclosure of Invention

The utility model aims at overcoming above-mentioned technical shortcoming and providing a novel reading clamp, the utility model has the advantages of reasonable design, through telescopic link regulation the device the height and the angle, through articulated have clamping device, realize the clamp of books tightly and 360 degrees rotations.

The utility model provides a technical scheme that technical problem adopted does: a novel book holder comprises a U-shaped frame, a locking knob, a telescopic rod and a clamping device, wherein the upper end of the U-shaped frame is provided with a clamping groove, the telescopic rod is clamped in the clamping groove, the left end of the telescopic rod is hinged with the clamping groove, the upper left corner of the front end surface of the U-shaped frame is screwed with the locking knob, the rear end of the locking knob is in contact with and connected with the telescopic rod, on one hand, the height and the angle of the book holder are convenient to adjust, on the other hand, the book holder is convenient to store, and the space occupancy rate is reduced, the clamping device comprises a bottom plate, a through groove, an L-shaped clamping plate, teeth, a supporting plate, a gear and a rotating shaft, the middle of the upper left end of the bottom plate is hinged with the telescopic rod, the lower right end of the bottom plate is fixedly connected with the supporting plate, the through groove is arranged in the middle of, and the front L-shaped clamping plate and the rear L-shaped clamping plate are inserted in a staggered manner, so that on one hand, the length of the L-shaped clamping plate is adjusted, and therefore different books or electronic products are adjusted, on the other hand, the two L-shaped clamping plates are inserted into each other for limiting, a rotating shaft is inserted into the middle of the through groove, a gear is fixedly connected to the rotating shaft, and the gear is meshed with the teeth.

Furthermore, the upper end of the telescopic rod and the left lower end of the U-shaped frame are in threaded connection with locking knobs, so that the device is convenient to lock.

Further, the contained angle of U type frame right-hand member face and horizontal plane is 60 degrees and suits with the bottom plate, and when the telescopic link shrink and joint were in the draw-in groove, the bottom plate just was inclined at 30 degrees angles with the contact connection of U type frame, conveniently reads.

The utility model discloses the beneficial effect who has is: the utility model has the advantages of reasonable design, through telescopic link regulation the device's height and angle, through articulated have clamping device, realize the clamp of books tightly and 360 degrees rotations, have good popularization prospect.
