The specific embodiment

For example the present invention is done description in more detail below in conjunction with accompanying drawing:

Embodiment 1:

In conjunction with Fig. 1～6, the style of calligraphy 1 below is carried in the bottom and linear bearing 6 is connected, linear bearing 6 is constrained on the linear bearing guide rail 10, be the bottom carry the style of calligraphy 1 can by linear bearing 6 along linear bearing guide rail 10 art skatings, the back side of carrying the style of calligraphy 1 in the bottom is fixed with steel wire rope 7, this steel wire rope 7 is connected on the reel 9, reel 9 is fixed on the output shaft of spiral motor 8, i.e. rotation by spiral motor 8 drives reel 9 rotations, make 9 pairs of steel wire ropes of reel 7 carry out retractable cable, and then drive the bottom and carry the style of calligraphy 1 and move freely along linear bearing guide rail 10 front and back.The below of outside framework 3 is fixed with a worm screw motor 12, this worm screw motor 12 output shaft fixed connections one worm screw 13, the other end of worm screw 13 is fixing by worm screw seat 14, the worm gear 11 that worm screw 13 and is fixed on the leading screw 4 matches, rotation by worm screw motor 12 drives worm gear 11 rotations, because worm gear 11 is connected with leading screw 4, makes the rotating band movable wire thick stick nut 5 of leading screw 4 move in the vertical direction, and the two ends of the style of calligraphy 2 are carried on top and feed screw nut 5 is fixing, thereby can realize that top carries the vertical of the style of calligraphy 2 and move.

The technical scheme of this solid lifting bookshelf is as follows: the general structure of whole bookshelf is by outside framework 3 support as a whole.The all wt that the style of calligraphy 2 is carried on top is carried by leading screw 4.In the bottom of outside framework 3, a worm screw motor 12 links to each other by worm screw seat 14 with worm screw 13, and whole worm screw seat 14 then is fixed on the bottom of outside framework.In the bottom of leading screw 4, the worm gear 11 that is connected, worm gear 11 drives leading screws 4 rotations under the drive of worm screw 13, carries the feed screw nut 5 of the style of calligraphy 2 and makes whole top carry the style of calligraphy 2 can to move in vertical direction by being fixed on top.Because this leading screw 4 has self-locking performance, therefore, can carry the location that the style of calligraphy 2 carries out on the vertical direction to top.The moving by fixing two linear bearings 6 thereunder of horizontal direction that the style of calligraphy 2 is carried in the bottom determines jointly that with the linear bearing guide rail 10 that is fixed on outside framework 3 bottoms its type of drive is to be fixed on the back and forth folding and unfolding realization of the spiral motor 8 of outside framework 3 bottoms by 9 pairs of steel wire ropes 7 of reel.Fixedly be tied with two strand steel wire ropes 7 on the reel 9, and the winding direction of 7 pairs of reels 9 of two strand steel wire ropes is opposite, like this, when spiral motor 8 when a certain direction is rotated, can guarantee a strand steel wire rope 7 kinkings, another strand unwrapping wire, thus steel wire rope 7 closed loops formed, and promptly the front and back of carrying the style of calligraphy 1, bottom move horizontally by spiral motor 8 positive and negative and transfer control.Moving forward and backward of the style of calligraphy 1 carried in the bottom, and vertical the moving of carrying the style of calligraphy 2 for top provides the space, and both are vertical, the motion of level cooperates, and make the function that picks and places high-rise books be achieved.

When the selected books of reader carry the style of calligraphy 1 in lower bottom, the same with common bookshelf, can normally pick and place, when selected books carry the style of calligraphy 2 on higher top, the reader can press and receive outside button, at this moment, spiral motor 8 rotates and drives reel 9 rotations, carry the style of calligraphy 1 and pull backward by being fixed on 7 pairs of bottoms of steel wire rope on the reel 9, at this moment, the bottom is carried the style of calligraphy 1 and is rearward moved along linear bearing guide rail 10 by fixing linear bearing 6 thereunder, displacement is a bit larger tham the width that the style of calligraphy 2 is carried on top, can descend smoothly so that the style of calligraphy 2 is carried on top, this distance is guaranteed by the accurate control of the mode position of the spiral motor 8 that has encoder.Carry after the style of calligraphy 1 withdraws in the bottom, 10 rotations of worm screw motor drive worm gear 11 rotations, because worm gear 11 and leading screw 4 relative fixed, therefore, leading screw 4 can rotate under the drive of worm gear 11, drop to the position that the reader needs smoothly thereby make top carry the style of calligraphy 2, reach the purpose of conveniently getting book.When the reader has got postscript, press the control button that resets, can make top carry the style of calligraphy 2 and revert to initial position, afterwards, under the drive of spiral motor 8, the bottom is carried the style of calligraphy 1 and is also got back to original state.
