Description

Technical Field

[0001] The utility model relates to the technical field of book racks, in particular to a book rack with a mechanism for preventing books from tipping over. Background Art

[0002] Bookshelves, also known as bookcases, are used and are commonly found in libraries, bookstores, supermarkets and other places. There are many styles of bookshelves, and they are generally divided into wooden bookshelves and iron bookshelves according to the materials. Wooden bookshelves can hold a large number of books, so there are many of them; while iron bookshelves combine placement and display, so they are commonly found in bookstores and supermarkets.

[0003] For example, the public document with application number 202320478820.6 discloses a book with a structure to prevent books from tipping over. The utility model fixes the book by pushing a clamping plate, and then charges the electromagnet to generate magnetic force and adsorb the magnet, thereby fixing the book. When the inside of the box is humid, the heating wire is heated, and then the fan generates wind. When the wind passes through the heating wire, it takes away the heat of the heating wire and turns into hot air. Then, the book in the box is heated through the air duct to prevent the book from being too humid. At the same time, the moisture in the box is absorbed by the lime layer, so that the book shelf has the advantages of limiting the position of books and preventing moisture. However, when borrowers return books, the books are inserted and placed with the loose ends facing inward and the bound ends facing outward, which may easily cause the corners of the two sides of the loose ends of the books to curl up when they are returned and inserted, or the books may have curled up when they are borrowed. At this time, directly clamping and fixing the books will affect the shape quality of the books, causing wrinkles on both sides of the books, affecting borrowing and use.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a bookshelf with a book-toppling prevention mechanism is proposed. Utility Model Content

[0005] The utility model aims to provide a book shelf with a book-tip-proof mechanism to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bookshelf with a book-tip-proof mechanism, comprising a support frame, a three-layer storage board is fixedly arranged in the middle of the opposite side of the support frame, a level label is fixedly arranged on the front side of the surface of the support frame above each layer of the storage board, a sequence label is fixedly installed on the front side of the surface of the storage board, storage bins are evenly distributed and fixedly installed above the surface of the storage board, a limited sliding groove is provided at the bottom of the inner surface of the storage bins, a clamping mechanism is arranged inside the storage bins, and a smoothing mechanism is arranged on the surface of the clamping mechanism.

[0007] Preferably, the clamping mechanism comprises a sliding plate slidably arranged on the inner surface of the limiting sliding groove, and pushing rods are fixedly arranged on the bottom of the inner surface of the placement bin on both sides of the surface of the sliding plate so as to slide in contact with the storage bin.

[0008] Preferably, the clamping mechanism further comprises movable grooves opened at the rear ends of the left and right sides of the inner surface of the placement bin, and a tension spring is fixedly mounted at the opposite end of the inner surface of the movable groove.

[0009] Preferably, the clamping mechanism further comprises a slider fixedly mounted at one end of the tension spring, a clamping plate fixedly mounted on the front end of the surface of the slider, and an opposite side of the surface of the clamping plate is arranged as an inclined surface, which is slidably fitted with the pushing rod.

[0010] Preferably, the smoothing mechanism comprises a connecting rod fixedly arranged in a middle groove on one side opposite to the clamping plate, and two inclined movable arms are rotatably arranged on the surface of the connecting rod.

[0011] Preferably, the smoothing mechanism further comprises a telescopic spring fixedly mounted on the middle portion of one side opposite to the movable arm, and a mounting bracket is fixedly mounted on the end of the movable arm.

[0012] Preferably, the smoothing mechanism further comprises rollers rotatably arranged on the inner side of the mounting frame, and the rollers protrude from the grooves on both sides of the placement bin.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model provides hierarchical signs, sequence signs and placement bins, and uses hierarchical signs and sequence signs to guide the location of required books. Borrowers can find required books more quickly and conveniently by using the guidance. The placement bins are used to store each book separately, so that books can be effectively distinguished and placed, avoiding confusion due to stacking, and making it convenient for borrowers to take them.

[0015] 2. The utility model adopts the arrangement of the limit slide groove, the clamping mechanism, the sliding plate, the pushing rod, the moving groove, the tension spring, the slider and the clamping plate. When the book is placed in the storage bin, the sliding plate will be pushed to move along the limit slide groove, thereby driving the pushing rod to move backward, and the inclined surface will be used to push the clamping plate to move out and extend toward the middle of the storage bin through the slider along the moving groove, so that the stored books can be clamped, effectively preventing the books from falling over, and making the book storage more stable;

[0016] 3. The utility model arranges a smoothing mechanism, a connecting rod, a movable arm, a telescopic spring, a mounting frame and a roller. When the clamping mechanism fixes the book, the roller preferentially contacts the surfaces of both sides of the book. As the clamping plate moves toward the middle, the movable arm obliquely arranged toward the middle is pressed. The movable arm expands toward both sides under the rolling of the roller, so that the roller rolls and presses from the middle of the book to the front and rear sides of the book to smooth both sides of the surface of the book, thereby avoiding curling and warping of the corners of the book when it is stored or when people borrow, use and return it, improving the quality of book storage and preventing the book from being damaged and deformed. At the same time, after the telescopic spring is expanded and stretched, it has a pulling force to contract toward the middle, pulling the movable arm to move toward the middle, while the length of the movable arm remains unchanged, and the book occupies a part of the space in the storage bin. The force moving toward the middle is converted into a clamping force pushing toward the middle, thereby further clamping and fixing the book, and further improving the stability of book storage.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 2As shown, a bookshelf with a mechanism to prevent books from tipping over comprises a support frame 1, a three-layer storage board 2 is fixedly arranged in the middle of an opposite side of the support frame 1, a level label 3 is fixedly arranged on the front side of the surface of the support frame 1 above each layer of the storage board 2, a sequence label 4 is fixedly installed on the front side of the surface of the storage board 2, storage bins 5 are evenly distributed and fixedly installed above the surface of the storage board 2, a limiting slide groove 6 is provided at the bottom of the inner surface of the storage bin 5, a clamping mechanism 7 is arranged inside the storage bin 5, and a smoothing mechanism 8 is arranged on the surface of the clamping mechanism 7.

[0024] By adopting the above technical solution, the level sign 3 and the sequence sign 4 guide the location of the required books, and the borrower can find the required books more quickly and conveniently by using the guidance; the level sign 3 and the sequence sign 4 can be actively replaced according to different levels and positions;

[0025] The placement compartment 5 is used to store each book separately, so that the books can be effectively distinguished and placed, avoiding confusion due to stacking, and making it convenient for borrowers to take them.

[0026] like Figure 2-Figure 3 As shown, the clamping mechanism 7 includes a sliding plate 701 slidably arranged on the inner surface of the limiting slide groove 6, and a pushing rod 702 is fixedly arranged on the bottom of the inner surface of the placement bin 5 on both sides of the surface of the sliding plate 701 to slide in contact with it.

[0027] By adopting the above technical solution, the limiting slide groove 6 limits the maximum backward movement distance of the sliding plate 701, and the sliding plate 701 is used as a rear baffle to prevent books from falling from the rear.

[0028] Furthermore, the clamping mechanism 7 also includes a movable groove 703 opened at the rear ends of the left and right sides of the inner surface of the placement bin 5, and a tension spring 704 is fixedly installed at the opposite end of the inner surface of the movable groove 703.

[0029] By adopting the above technical solution, the tension spring 704 can reset the clamping mechanism 7 after losing the book pushing limit.

[0030] Furthermore, the clamping mechanism 7 also includes a slider 705 fixedly installed at one end of the tension spring 704, and a clamping plate 706 is fixedly installed on the front end of the surface of the slider 705. The opposite side of the surface of the clamping plate 706 is set as an inclined surface, which slides and fits with the pushing rod 702.

[0031] By adopting the above technical solution, the position of the pushing rod 702 remains unchanged, and the inclined surface can gradually push the clamping plate 706 to protrude toward the middle to clamp and fix the book;

[0032] The slider 705 is slidably disposed inside the moving groove 703 . Under the limit of the moving groove 703 , the movement of the clamping plate 706 is more stable, and the restoring force of the tension spring 704 is also transmitted.

[0033] like Figure 2 and Figure 4 As shown, the smoothing mechanism 8 includes a connecting rod 801 fixedly arranged in a middle groove on one side opposite to the clamping plate 706, and two inclined movable arms 802 are rotatably arranged on the surface of the connecting rod 801.

[0034] By adopting the above technical solution, the movable arm 802 is slightly tilted and protrudes from the grooves on both sides of the placement bin 5, so that when the clamping plate 706 clamps the book, the movable arm 802 is pushed and expanded from the middle of the book to the front and rear sides using the oblique setting state.

[0035] Furthermore, the smoothing mechanism 8 also includes a telescopic spring 803 fixedly installed in the middle of one side opposite to the movable arm 802, and a mounting bracket 804 is fixedly provided at the end of the movable arm 802.

[0036] By adopting the above technical solution, after the telescopic spring 803 is expanded and stretched, it has a pulling force to contract toward the middle, pulling the movable arm 802 to move toward the middle, while the length of the movable arm 802 remains unchanged, and the books occupy a part of the space of the placement bin 5. The force moving toward the middle will be converted into a clamping force pushing toward the middle, thereby further clamping and fixing the books.

[0037] Furthermore, the smoothing mechanism 8 also includes rollers 805 rotatably arranged on the inner side of the mounting frame 804 , and the rollers 805 protrude from the grooves on both sides of the placement bin 5 .

[0038] By adopting the above technical solution, the roller 805 is located at the end of the movable arm 802, and has the highest priority in contacting the book. The movable arm 802 pushes and expands, which pushes the roller 805 to roll from the middle to the front and rear sides to adhere to the surface of the book, smoothing both sides of the book surface, thereby preventing the corners of the book from curling when it is stored or when people borrow, use and return it;

[0039] The rotation of the roller 805 also makes it more convenient to borrow and take books, avoiding direct contact with the hard clamping plate, which would cause the surface of the book to be worn and scratched when the book is drawn out.

[0040] Working principle: When using the bookshelf with the anti-book tipping mechanism, first, when borrowing books, the level label 3 and the sequence label 4 are used to guide the location of the required books. Borrowers can use the guidance to find the required books more quickly and conveniently. After borrowing is completed, the placement bin 5 stores each book separately, so that the books can be effectively distinguished and placed. When a book is inserted into the corresponding placement bin 5, it will push the sliding plate 701 to move along the limiting slide groove 6, thereby driving the pushing rod 702 to move backward, and use the inclined surface to push the clamping plate 706 to move out and extend to the middle of the placement bin 5 through the slider 705 along the moving groove 703, so that the stored books can be clamped. When the clamping mechanism 7 fixes the book, the roller 80 5 preferentially contacts the two side surfaces of the book. As the clamping plate 706 moves toward the middle, it will press the obliquely arranged movable arm 802 toward the middle. The movable arm 802 will expand toward both sides under the rolling of the roller 805, so that the roller 805 rolls and presses from the middle of the book to the front and rear sides of the book to smooth the two sides of the book surface. At the same time, after the expansion and stretching of the telescopic spring 803, it has a pulling force to contract toward the middle, pulling the movable arm 802 to move toward the middle, while the length of the movable arm 802 remains unchanged. The book occupies a part of the space of the placement bin 5. The force moving toward the middle will be converted into a clamping force pushing toward the middle, thereby further clamping and fixing the book. This is the working principle of the book rack with a book-tip-proof mechanism.
