Description

Technical Field

[0001] The utility model relates to the technical field of book management equipment, in particular to a closed book return box. Background Art

[0002] The tops of the book return boxes installed in existing libraries are mostly open. For example, a book return box disclosed in publication number CN204908494U uses a scissor-type elastic structure and a vertical guide method to enable the lifting platform to maintain horizontal lifting. However, the top of the lifting plate is an open structure, and there is a risk of books being taken by mistake. Summary of the invention

[0003] The utility model provides a closed book return box to overcome the deficiencies of the prior art.

[0004] In order to achieve the above-mentioned purpose, a closed book return box is designed, including a box body, which is closed on all sides and the top, a book return port is provided on the upper side of one side of the box body, a lifting plate is provided in the box body, a scissors support structure is provided below the lifting plate, the scissors support structure includes at least one set of scissors arms, an upper fixed seat and an upper guide groove are provided at the bottom of the lifting plate, a lower fixed seat and a lower guide groove are provided at the inner bottom of the box body, one side of the upper end of the scissors arm is rotatably connected to the upper fixed seat, and the other side of the upper end is slidably connected to the upper guide groove, one side of the lower end of the scissors arm is rotatably connected to the lower fixed seat, and the other side of the lower end is slidably connected to the lower guide groove, a spring is connected between the two sides of the top of the scissors arm and between the two sides of the bottom, and a box door with a lock is provided on one side of the box body.

[0005] The box body is provided with two book return ports, two sets of lifting plates and a scissor support structure are arranged inside the box body, and a partition is arranged in the middle of the inner side of the box body for separating the two sets of lifting plates and the scissor support structure.

[0006] The scissor arms are arranged in two groups in parallel and are respectively arranged on both sides below the lifting plate.

[0007] The book return opening is a long strip-shaped opening.

[0008] A handle is provided on one side above the box body.

[0009] Rollers are arranged under the box body.

[0010] Compared with the prior art, after a book is put in from the book return opening, the lifting plate will drop as the gravity of the book increases, so the book can be placed on the upper side without being damaged, and it is not easy to take out the book after it is put in from the book return opening, so it can prevent the book from being taken by mistake.

DETAILED DESCRIPTION

[0015] The utility model is further described below with reference to the accompanying drawings.

[0016] like Figure 1-Figure 3 As shown, the box body 1 is closed on all sides and the top, a book return port 2 is provided on the upper side of one side of the box body 1, a lifting plate 3 is provided inside the box body 1, a scissors support structure 4 is provided below the lifting plate 3, the scissors support structure 4 includes at least one set of scissors arms 4-1, an upper fixed seat 4-2 and an upper guide groove 4-3 are provided at the bottom of the lifting plate 3, a lower fixed seat 4-4 and a lower guide groove 4-5 are provided at the inner bottom of the box body 1, one side of the upper end of the scissors arm 4-1 is rotatably connected to the upper fixed seat 4-2, and the other side of the upper end is slidably connected to the upper guide groove 4-3, one side of the lower end of the scissors arm 4-1 is rotatably connected to the lower fixed seat 4-4, and the other side of the lower end is slidably connected to the lower guide groove 4-5, a spring 4-6 is connected between the two sides of the top of the scissors arm 4-1 and between the two sides of the bottom, and a locked box door 6 is provided on one side of the box body 1.

[0017] The box body 1 is provided with two book return ports 2 , two sets of lifting plates 3 and a scissor support structure 4 are arranged inside the box body 1 , and a partition plate 7 is arranged in the middle of the box body 1 for separating the two sets of lifting plates 3 and the scissor support structure 4 .

[0018] The scissor support device 4 is a scissor-type structure, and springs are arranged between the connecting rods of the scissor structure.

[0019] The book return opening 2 is a long strip opening.

[0020] A handle 8 is provided on one side of the upper side of the box body 1 .

[0021] A roller 5 is provided below the box body 1 .

[0022] When the utility model is used, the books are placed into the box body 1 from the book return port 2. The book return port 2 is long and strip-shaped, which is convenient for placing books. After the books are placed, they fall on the lifting plate 3. A scissor support structure 4 is provided on both sides below the lifting plate 3, so that the lifting plate 3 can maintain balance. The two ends of the scissor arm 4-1 are respectively provided with springs 4-6 to make the scissor arm 4-1 have an upward elastic force. When no books are placed, the lifting plate 3 is in a position close to the bottom of the book return port 2. Under the action of the gravity of the placed books, the lifting plate 3 drops, which can reduce the distance the books fall and prevent the books from being damaged. The books can be stacked in order in the box body 1. Since the books are stacked in a pile, two book return ports are provided in the box body 1 to increase the capacity for returning books. The staff regularly pulls the book return box to the library, opens the book return box and scans the code to confirm the return to the library.
