Description

Three-dimensional lifting bookshelf

technical field

The invention relates to a bookshelf for storing books.

Background technique

At present, there is a problem in today's libraries, that is, it is inconvenient to take and put books. In relatively large libraries, the number of books is relatively large, and in order to save space, the bookshelves are often very high. It is troublesome, and the method of picking and placing high-level books is often to pick and place high-level ladders. Because readers need to carry out high-altitude operations to pick and place books, this creates a greater safety hazard, and wastes readers' time and reduces work. Learning efficiency.

The "liftable bookshelf" with the patent No. 200820130510.0 has a fixed frame, and a liftable bookshelf moves in the fixed frame through a slideway, that is, the bookshelf has only one movable book-loading platform, and the platform has only one vertical direction. degrees of freedom. It has the following disadvantages: the volume of books is small, there are few movable book-carrying platforms, and the movement is not flexible enough.

Contents of the invention

The object of the present invention is to provide a three-dimensional lifting bookshelf that eliminates the potential safety hazard of climbing to pick and place books and greatly saves the occupied area.

The purpose of the present invention is achieved like this:

The three-dimensional lifting bookshelf of the present invention includes an outer frame, and is characterized in that it also includes a lower book-carrying body, an upper book-carrying body, a screw, a steel wire rope, a reel, a linear bearing guide rail, a worm wheel, a worm, a lower book-carrying body and an upper book-carrying body. The books are all installed in the outer frame, the worm seat is fixed on the outer frame, the screw is installed on the worm seat through the worm wheel and the worm, the screw is also connected with the upper book body, and the linear bearing guide rail is installed between the lower book body and the outer frame , The reel is installed on the linear bearing guide rail, two strands of the wire rope are wound on the reel, and the worm and the reel are driven by the worm motor and the reel motor respectively.

The advantage of the present invention is that books that are not easy to be placed on high floors can be transferred to a more suitable height through the transmission device, thereby avoiding the safety hazard of needing to climb up to take and place, and making full use of the space, greatly saving the occupied area.

Detailed ways

The present invention is described in more detail below in conjunction with accompanying drawing example:

Implementation mode 1:

In combination with Figures 1 to 6, the bottom of the lower book-loading body 1 is fixedly connected with the linear bearing 6, and the linear bearing 6 is constrained on the linear bearing guide rail 10, that is, the lower book-loading body 1 can slide freely along the linear bearing guide rail 10 through the linear bearing 6 , a steel wire rope 7 is fixedly connected to the back side of the lower book-loading body 1, and the steel wire rope 7 is connected to the winding wheel 9, and the winding wheel 9 is fixed on the output shaft of the winding motor 8, that is, through the rotation of the winding motor 8 The winding wheel 9 is driven to rotate, so that the winding wheel 9 carries out rewinding and unwinding of the steel wire rope 7, and then drives the lower book-loading body 1 to move freely back and forth along the linear bearing guide rail 10. A worm motor 12 is fixed below the outer frame 3, and the output shaft of the worm motor 12 is fixedly connected with a worm 13, and the other end of the worm 13 is fixed by a worm seat 14, and the worm 13 cooperates with a worm wheel 11 fixed on the lead screw 4, The rotation of the worm motor 12 drives the worm wheel 11 to rotate. Since the worm wheel 11 is fixedly connected with the lead screw 4, the rotation of the lead screw 4 drives the lead screw nut 5 to move in the vertical direction, and the two ends of the upper book-loading body 2 are connected to the lead screw nut. 5 is fixed, so that the vertical movement of the upper book-loading body 2 can be realized.

The technical scheme of the three-dimensional lifting bookshelf is as follows: the overall structure of the whole bookshelf is supported by the outer frame 3 as a whole. All the weight of the upper book carrier 2 is carried by the lead screw 4 . At the bottom of the outer frame 3, a worm motor 12 is connected with the worm 13 through a worm seat 14, and the whole worm seat 14 is fixed on the bottom of the outer frame. At the bottom of the leading screw 4, a worm wheel 11 is fixedly connected. Driven by the worm screw 13, the worm wheel 11 drives the leading screw 4 to rotate, and the whole upper book carrying body 2 can be rotated vertically by the screw nut 5 fixed on the upper book carrying body 2. direction of movement. Since the screw 4 is self-locking, it is possible to position the upper book carrier 2 in the vertical direction. The movement of the lower book-loading body 2 in the horizontal direction is jointly determined by the two linear bearings 6 fixed below it and the linear bearing guide rail 10 fixed on the bottom of the outer frame 3, and the driving method is that the winding motor 8 fixed on the bottom of the outer frame 3 passes through The reel 9 realizes the back and forth of the wire rope 7. Two strands of steel wire ropes 7 are fixedly wound on the reel 9, and the winding directions of the two strands of steel wire ropes 7 to the reel 9 are opposite. , another strand of pay-off, thereby forming a closed loop of wire rope 7, that is, the front and rear horizontal movement of the lower loading body 1 is controlled by the positive and negative rotation of the winding motor 8. The back and forth movement of the lower book-carrying body 1 provides space for the vertical movement of the upper book-carrying body 2, and the vertical and horizontal movement of the two together enables the function of picking and placing high-level books to be realized.

When the book selected by the reader is loaded with the book body 1 in the lower lower part, it can be taken and placed normally like an ordinary bookshelf. When the selected book is loaded with the book body 2 in the higher upper part, the reader can press to receive External button, at this time, the winding motor 8 rotates to drive the winding wheel 9 to rotate, and the lower loading book body 1 is dragged backward by the steel wire rope 7 fixed on the winding wheel 9, at this time, the lower loading book body 1 The linear bearing 6 fixed below it moves to the rear along the linear bearing guide rail 10, and the moving distance is slightly larger than the width of the upper book-loading body 2, so that the upper book-loading body 2 can descend smoothly. The precise control of the position mode of the wire motor 8 is guaranteed. After the lower book-loading body 1 is withdrawn, the worm motor 10 rotates to drive the worm wheel 11 to rotate. Since the worm wheel 11 and the lead screw 4 are relatively fixed, the lead screw 4 can rotate under the drive of the worm wheel 11, thereby making the upper book-loading body 2 It smoothly descends to the position required by the reader to achieve the purpose of conveniently picking up the book. After the reader has finished taking the book, press the reset control button to make the upper book-carrying body 2 return to the initial position, and then, driven by the winding motor 8, the lower book-carrying body 1 also returns to the initial state.
