Description

Technical Field

[0001] This utility model relates to the field of book transfer technology, and in particular to a transfer vehicle for classifying library books. Background Technology

[0002] After books are returned to the library, librarians need to reposition them in their corresponding areas, requiring book transfer during this process. An existing library book sorting transfer cart (publication number CN 222452299 U) uses a clamping mechanism in each book stacking space. This mechanism includes a pressure plate, a moving part, and a locking element to secure the moving part. The moving part drives the pressure plate to press and fix the books, and the locking element secures their position. During transport, the pressure plate keeps the books in place, improving stability and preventing tipping or falling. However, the locking mechanism is cumbersome to operate, causing inconvenience. Utility Model Content

[0003] The purpose of this invention is to provide a transfer vehicle for classifying library books in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A library book sorting and transfer vehicle includes a mobile support mechanism. The mobile support mechanism includes a base plate with side plates fixed to both sides of the upper part of the base plate and a moving wheel installed at the lower part of the base plate. At least two layers of limiting mechanisms for clamping and fixing upright books are provided on the upper part of the base plate between the side plates. The limiting mechanism includes a guide assembly with a clamping assembly for clamping books during sliding between the side plates. The guide assembly includes a support frame horizontally arranged between the side plates, with two guide posts passing through the inner cavity of the support frame. An opening slot is opened on the bottom surface of the support frame. The clamping assembly includes a double rack arranged in the inner cavity of the support frame between the guide posts. The teeth on the double rack are inclined towards the side plates. An adjustment plate passing through the opening slot is provided on the guide post. A slide rod passes longitudinally through the adjustment plate. A wedge plate cooperating with the double rack is fixed to the rear end of the slide rod. A first spring is sleeved on the slide rod between the wedge plate and the adjustment plate. Slide grooves are opened on the front and rear walls of the support frame, and a rotating cam handle is connected to the front end of the slide rod through the slide groove.

[0006] Further configuration: The clamping components are positioned in two locations opposite each other on the guide components.

[0007] Further details: A handle is fixed on the side adjacent to the adjustment plate.

[0008] Further settings: The adjustment plate is slidably connected to the guide post, and the slide rod is slidably connected to the slide groove.

[0009] Further configuration: The rotating cam handle and the slide rod are rotatably connected via a pin.

[0010] Further configuration: A buffer plate is provided on the side of the adjustment plate near the side plate. The buffer plate is slidably connected to the guide post through the opening slot.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-5 As shown, a library book sorting transfer vehicle includes a mobile support mechanism. The mobile support mechanism includes a base plate 11, side plates 12 are fixed on both sides of the upper end of the base plate 11, and a handrail hole 121 is opened at the upper position of the side plate 12 to facilitate hand holding of the side plate 12 and pushing the whole movement. A moving wheel 13 is installed at the lower end of the base plate 11. At least two layers of limiting mechanism for clamping and fixing the upright books are provided on the upper side of the base plate 11 between the side plates 12.

[0025] In this embodiment: the limiting mechanism includes a guide component, and the guide component is provided with a clamping component that clamps the book during the sliding process between the side plates 12;

[0026] The guide assembly includes a support frame 21 horizontally arranged between the side plates 12. The support frame 21 is used to place the book vertically. Two guide posts 22 pass through the inner cavity of the support frame 21. An opening groove 201 is provided on the bottom surface of the support frame 21.

[0027] The clamping assembly has two opposing positions on the guide assembly. The clamping assembly includes a double rack 25 located between guide posts 22 within the inner cavity of the support frame 21. The teeth on the double rack 25 are inclined towards the side plate 12. An adjusting plate 23 passing through an opening slot 201 is provided on the guide post 22. A slide rod 26 extends longitudinally through the adjusting plate 23. A wedge-shaped plate 27 cooperating with the double rack 25 is fixed to the rear end of the slide rod 26. A first spring 28 is sleeved on the slide rod 26 between the wedge plate 27 and the adjusting plate 23. Slide grooves 202 are provided on the front and rear walls of the support frame 21. The front end of the slide rod 26 passes through the slide grooves 202 and is connected to a rotating cam handle 29. A handle 24 is fixed to the adjacent side of the adjusting plate 23 for easy... The adjustment plate 23 is pushed and adjusted; the adjustment plate 23 is slidably connected to the guide post 22, and the slide rod 26 is slidably connected to the slide groove 202; the rotating cam handle 29 is rotatably connected to the slide rod 26 through a pin shaft. By pushing the adjustment plate 23 closer to the side plate 12, during the movement of the adjustment plate 23, the wedge plate 27 slides with the teeth on the double rack 25, and the pusher slide rod 26 overcomes the first spring 28 to push the wedge plate 27 outward. Then the wedge plate 27 is reset under the force of the first spring 28, and the position of the adjustment plate 23 is fixed until the buffer plate 210 contacts the book, clamping the book between the buffer plate 210 and the side plate 12 to prevent the book from falling and becoming messy when the whole is moved.

[0028] A buffer plate 210 is provided on the side of the adjusting plate 23 near the side plate 12. The buffer plate 210 is slidably connected to the guide post 22 through the opening slot 201. A second spring 211 is provided between the adjusting plate 23 and the buffer plate 210 on the outer ring of the guide post 22. The second spring 211 is fixedly connected to the adjusting plate 23 and the buffer plate 210. During the process of the adjusting plate 23 moving towards the book, the buffer plate 210 and the side plate 12 form a clamping effect on the book, and the second spring 211 makes a fine adjustment to the position of the buffer plate 210.

[0029] The working principle and usage process of this utility model are as follows: The book is placed vertically on the base plate 11 or the support frame 21 on the lower side, close to the side plate 12. By pushing the adjustment plate 23 closer to the side plate 12, during the movement of the adjustment plate 23, the wedge plate 27 slides against the teeth on the double rack 25. The push rod 26 overcomes the first spring 28 and pushes the wedge plate 27 outward. Then, the wedge plate 27 returns to its original position under the force of the first spring 28, fixing the position of the adjustment plate 23 until the buffer plate 210 contacts the book, clamping the book between the buffer plate 210 and the side plate 12 to prevent the book from falling and becoming messy when the whole is moved. When the adjustment plate 23 returns to its original position, the rotating cam handle 29 at the end of the rotating rod 26 points downward, causing the rotating cam handle 29 to push the rod 26 and pull the wedge plate 27 outward, separating it from the double rack 25, and quickly pushing the adjustment plate 23 to its original position.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
