[0016] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0017] See also Figure 1 and Figure 2 A transfer trolley for classifying books in a library comprises a vehicle body 1 and a book placing rack 2 arranged on the vehicle body 1, wherein a plurality of book stacking spaces 3 distributed up and down are formed on the book placing rack 2, and each book stacking space 3 is provided with two clamping mechanisms for clamping the placed books 10 to both ends, and each clamping mechanism comprises a pressing plate 4, a moving member 5 for driving the pressing plate 4 to move left and right, and a locking member 6 for locking the position of the moving member 5, and the moving member 5 comprises a slider 501 and a slide groove 502, and the upper and lower ends of the inner side of the book stacking space 3 are respectively provided with slide grooves 502, and the cross-sectional shape of the slide groove 502 can be T-shaped or square, and the two ends of the slider 501 are respectively slidably connected in the two slide grooves 502, and the slider 501 can only move horizontally along the slide groove 502 through the limitation of the slide groove 502, but cannot rotate, and the pressing plate 4 is installed on the slider 501, and the slider 501 can move left and right along the slide groove 502, thereby driving the pressing plate 4 to move.

[0018] In this embodiment, when the books are placed, the sliding slider 501 moves along the slide groove 502, so that the pressing plate 4 is in close contact with the books to press the books tightly, and then the position of the slider 501 is locked by using the locking member 6, so that the pressing plate 4 can be used to press and fix the books, thereby improving the stability of book transportation and avoiding the problem of tipping over or falling during transportation.

[0019] See also Figure 1 and Figure 2In some embodiments, the locking member 6 includes a slot 601 and a locking tongue 602. A plurality of slots 601 are equidistantly arranged at the top of the book stacking space 3 along the extension direction of the slide groove 502. The slider 501 is matched with a sliding sleeve 603 that can move up and down. The locking tongue 602 is fixedly installed on the sliding sleeve 603. A return spring 604 is connected between the sliding sleeve 603 and the slider 501. The return spring 604 is sleeved on the slider 501, and the upper end is fixedly connected to the sliding sleeve 603, and the lower end is connected to the stop boss 11 on the slider 501. The stop boss 11 at the lower end of the slider 501 is fixedly connected to a baffle 605 through a connecting plate 12. The baffle 605 is fixedly connected to the back of the pressure plate 4 through a plurality of adjustment springs 606.

[0020] In this embodiment, when it is necessary to move the pressure plate 4 to press the book, it is only necessary to pull down the sliding sleeve 603 to drive the locking tongue 602 to withdraw from the slot 601, and then slide the slider 501 to move the pressure plate 4 to the position for pressing the book. Thereafter, the sliding sleeve 603 is released, and the restoring force provided by the restoring spring 604 is used to drive the sliding sleeve 603 to move up along the slider 501, and the locking tongue 602 is inserted into the corresponding slot 601, so that the position of the movable pressure plate 4 can be fixed, and the pressure plate 4 is not likely to fail in pressing the book.

[0021] In addition, the pressure plate 4 is connected to the baffle 605 on the slider 501 by adjusting the spring 606. Such a design allows the position between the pressure plate 4 and the slider 501 to be adjusted after the book is pressed, which can effectively ensure that each time the slider 501 moves, the locking tongue 602 can always align with a corresponding slot 601 and be inserted into the slot 601 to lock the position of the slider 501.

[0022] Specifically, the book rack 2 includes a bottom plate 201 and two side plates 202 arranged on both sides of the bottom plate 201. A middle partition 203 is vertically arranged on the bottom plate 201 to divide the space enclosed by the bottom plate 201 and the two side plates 202 into a front and a rear part. A plurality of horizontal partitions 204 equidistant from top to bottom are fixedly arranged on both sides of the middle partition 203. The plurality of horizontal partitions 204 divide the front and rear parts of the space into a plurality of book stacking spaces 3.

[0023] See also Figure 1 In order to facilitate the classification and transportation of books, a label slot 7 is provided at each book stacking space 3, and a book label 8 is placed in the label slot 7. Through the design of the label slot 7 and the book label 8, the type of the book body can be written on the surface of the book label 8, and then the book label 8 can be inserted into the label slot 7. When it is necessary to find the required book, the operator can observe the book label 8 through the observation hole of the label slot 7, and then the operator can find the required book according to the type written on the surface of the book label 8. In addition, in order to facilitate the movement of the trolley, a roller 9 is provided at the bottom of the vehicle body 1.
