Detailed Description

The invention will be described in further detail with reference to the following drawings and specific embodiments, without limiting the scope of protection and the application of the invention:

as shown in fig. 1 to 7, a bookshelf convenient for taking a book comprises a bottom plate 11, two side plates and an upper top plate, wherein a plurality of support plates 4 extending in the width direction of the bookshelf 1 are arranged above the bottom plate 11, the inner ends of the support plates 4 are hinged with the inner end of the bottom plate 11, and a first spring 5 is fixed in a gap between the outer end of the support plates 4 and the outer end of the bottom plate 11; a vertical rod 41 extending downwards is arranged on the bottom surface of the supporting plate 4 close to the outer end, a convex part 42 extending horizontally is arranged at the lower end of the vertical rod 41, the end surface of the convex part 42 is in a falling wedge shape, and the vertical rod 41 and the convex part 42 are combined to form an L-shaped first locking rod for limiting the vertical movement of the supporting plate 4; the bottom plate 11 is provided with a vertical cavity which is matched with the first lock rod of the support plate 4 in shape and moves up and down, the bottom plate 11 is also provided with a horizontal cavity, a second lock rod 111 which can move horizontally in the horizontal cavity is arranged in the horizontal cavity, one end of the second lock rod 111 in the horizontal cavity is connected with the wall of the horizontal cavity through a third spring 113 and a rope 114, the other end of the second lock rod extends out of the side edge of the bottom plate 11, the second lock rod 111 is provided with a locking block 112 corresponding to the convex part 42 of the first lock rod, the cross section of the locking block 112 is trapezoidal and is positioned above the convex part 42 of the first lock rod, the end surface of the locking block 112 and the wedge-shaped surface of the convex part 42 are correspondingly in a falling wedge shape, when external force is applied to the second lock rod 111 to enable the second lock rod 111 to move towards the inner end of the horizontal cavity, so that the locking block 112 moves out of the upper part of the convex part 42, the, the book placed on the support plate 4 is jacked up, the book taker can conveniently take the book away, at the moment, the external force of the second lock rod 111 is cancelled, the locking block 112 moves under the limitation of the length of the third spring 113 and the rope 114 to the position under the convex part 42, after the book taker finishes taking the book, the support plate 4 is pressed down by hand, the first lock rod moves downwards along with the support plate 4, because the end face of the convex part 42 in contact with the locking block 112 is a wedge-shaped face, when the first lock rod moves downwards, the locking block 112 rotates along with the rotation, when the convex part 42 of the first lock rod moves downwards to the position under the locking block, the locking block is rotated to the original position under the action of self torque to block the convex part 42, at the moment, the locking state is finished, and. Preferably, the width of the support plate 4 is set according to the size of the book or the required size to suit different needs.
