Description

Technical Field

[0001] This invention relates to the field of library book storage technology, and more particularly to a library book display rack that is easy to access. Background Technology

[0002] A library is an institution that collects, organizes, and preserves books and materials for people to read and reference. Libraries have a large collection of books, and in order to facilitate people's search for books and periodicals, they usually need to use book and periodical display shelves to display the books and periodicals in an orderly manner.

[0003] To prevent dust from falling onto books and periodicals, existing book and periodical display shelves are usually tilted from the upper front to the lower back. When people need to take or put away books and periodicals, they first need to manually rotate the shelf to the specified angle before taking or putting away the books and periodicals. Such book and periodical display shelves require manual rotation of the shelf. Therefore, we designed an automatic rotating shelf for easy access to library books and periodicals. Summary of the Invention

[0004] To overcome the drawback of requiring manual rotation of the storage rack, the technical problem is to provide an automated rotating storage rack for easy access to library books and periodicals.

[0005] The technical solution is as follows: A library book and periodical display rack that is easy to access includes a support frame, a rotating frame, and a storage rack. The upper and lower parts of the support frame are rotatably connected to the rotating frame, and the front of the rotating frame is connected to the storage rack. It also includes a sliding frame, a stepping mechanism, and an unfolding mechanism. Two sliding frames are slidably connected to the rear of the rotating frame. The front side of the front sliding frame contacts the storage rack, and the rear side of the front sliding frame contacts the rear sliding frame. The bottom of the support frame is provided with a stepping mechanism for automatically rotating the storage rack. An unfolding mechanism is provided between the support frame and the sliding frame for driving the books and periodicals in the upper and lower sliding frames to move progressively upward.

[0006] Optionally, the pedaling mechanism includes a pedal, a first telescopic spring, a first connecting rod, a first rotating rod, and a second connecting rod. The pedal is rotatably connected to the lower part of the support frame. The left and right sides of the bottom wall of the pedal are connected to the first telescopic springs, and the bottom ends of the first telescopic springs are connected to the support frame. The right side of the pedal is rotatably connected to the first connecting rod. The first rotating rod is rotatably connected to the first connecting rod. The second connecting rod is rotatably connected to the first connecting rod. The upper part of the second connecting rod is also rotatably connected to the first rotating rod. The upper first rotating rod is connected to the upper rotating frame, and the lower first rotating rod is connected to the lower rotating frame.

[0007] Optionally, the unfolding mechanism includes a fixed plate and a first fixed block. The left and right sides of the support frame are symmetrically connected with fixed plates, and each fixed plate has two guide grooves. The left and right sides of the sliding frame are equipped with first fixed blocks, each first fixed block corresponding to a guide groove, and the first fixed blocks slide in the corresponding guide grooves.

[0008] Optionally, it also includes a lighting mechanism for providing light for people to search for books and periodicals in dimly lit library rooms. The lighting mechanism includes a third connecting rod, a second rotating rod, a rotating disk, a fourth connecting rod, a third rotating rod, a rotating shaft, a torsion spring, and a lighting lamp. The third connecting rod is rotatably connected to the first rotating rod at the top. The second rotating rod is rotatably connected to the upper right part of the support frame. The second rotating rod is rotatably connected to the third connecting rod. The second rotating rod passes through the right side of the inner wall of the support frame. A rotating disk is installed at the left end of the second rotating rod. The fourth connecting rod is rotatably connected to the rotating disk at an eccentric position. The third rotating rod is rotatably connected to the fourth connecting rod. A rotating shaft is rotatably connected to the upper right side of the support frame. The third rotating rod is connected to the rotating shaft. A lighting lamp is rotatably connected to the inner top wall of the support frame. The lighting lamp is connected to the rotating shaft. A torsion spring is wound on the rotating shaft. The left and right ends of the torsion spring are connected to the support frame and the rotating shaft, respectively.

[0009] Optionally, it also includes a sorting mechanism for dividing the space at the front of the storage rack into three spaces. The sorting mechanism includes a locking tooth, a sliding member, a first buckle, and a second telescopic spring. The locking tooth is connected to the front side of the storage rack, and the sliding member is slidably connected to the front side of the storage rack. The sliding member is slidably connected to the locking tooth, and the first buckle is slidably connected to the sliding member. The first buckle slides inward and locks onto the locking tooth. The second telescopic spring is wound around the first buckle, and the inner and outer ends of the second telescopic spring are respectively connected to the first buckle and the sliding member.

[0010] Optionally, it also includes a clamping mechanism for fixing the pedal. The clamping mechanism includes a rotary chuck, a rotary buckle, and a second fixing block. The rotary chuck is rotatably connected to the lower part of the support frame. The top of the rotary chuck is higher in the front and lower in the back. The rotary buckle is rotatably connected to the lower left side of the front part of the support frame. The rotary buckle engages with the rotary chuck. The second fixing block is connected to the bottom wall of the pedal. The rotary chuck rotates 180 degrees to contact the second fixing block.

[0011] Optionally, it also includes a prompting mechanism for indicating the specific location of each book or periodical. The prompting mechanism includes a fixing member, a glass plate, and a second buckle. The front wall of the storage shelf is connected to the fixing member. The left and right sides of the front of the fixing member are slidably connected to the second buckle. The front of the fixing member is slidably connected to the glass plate, and the second buckle locks the left and right sides of the glass plate.

[0012] Optionally, it also includes a tension spring, with a tension spring wound around each of the second buckles, and both the inner and outer ends of the tension spring being connected to the fixing member and the second buckle respectively.

[0013] The beneficial effects are:

[0014] 1. By rotating the upper and lower rotating frames clockwise, the upper and lower storage racks and sliding racks are driven to rotate clockwise to a specified angle. At this time, people can take out and put in books and magazines. Thus, the storage racks can rotate automatically without the need for manual rotation of the storage racks and sliding racks, which helps to save manpower.

[0015] 2. By sliding the upper and lower sliding shelves upwards, the books and periodicals inside the upper and lower sliding shelves move upwards in a progressive manner, so that the books and periodicals in the upper and lower shelves are placed in a progressive manner, making it easier to see the titles of the books and periodicals and to help people find the books and periodicals they need.

[0016] 3. The rotating shaft drives the lamp to rotate, and the torsion spring undergoes torsional deformation. When the lamp rotates, the illumination area shifts to illuminate the books and periodicals, which can expand the illumination area and make it easier for people to find books and periodicals when the indoor lighting in the library is dim.

[0017] 4. By pulling the slider left and right, the slider can be moved to the designated position, thereby dividing the space in front of the storage shelf into three spaces. These three spaces can accommodate books and periodicals of different sizes, thus meeting the needs of storing books and periodicals of different sizes and making it highly versatile.

[0018] 5. When the rotary chuck is rotated counterclockwise, it rotates 180 degrees counterclockwise and contacts the second fixed block. At this time, the top of the rotary chuck is lower in the front and higher in the back, which can fix the pedal and prevent the books from shaking out due to accidental stepping on the pedal, thus ensuring the stable storage of the books.

[0019] 6. After the information cards are placed, people can view the exact location of each book and magazine in real time through the glass plate, which makes it easier for people to find the books and magazines and saves them time. Attached Figure Description

Detailed Implementation

[0037] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0038] Example 1

[0039] An easy-to-access library book and periodical display shelf, such as Figure 1 and Figure 2 As shown, it includes a support frame 1, a rotating frame 2, a storage rack 3, a sliding frame 4, a stepping mechanism 5, and an unfolding mechanism 6. The upper and lower parts of the support frame 1 are rotatably connected to the rotating frame 2. The front side of the rotating frame 2 is fixed to the storage rack 3. The rear side of the rotating frame 2 is slidably connected to two sliding frames 4. The two sliding frames 4 are symmetrically arranged on the front and rear sides. The front side of the sliding frame 4 contacts the storage rack 3, and the rear side of the front side of the sliding frame 4 contacts the rear side of the sliding frame 4. The bottom of the support frame 1 is provided with a stepping mechanism 5, and the unfolding mechanism 6 is provided between the support frame 1 and the sliding frame 4.

[0040] like Figure 1 and Figure 3 As shown, the pedaling mechanism 5 includes a pedal 51, a first telescopic spring 52, a first connecting rod 53, a first rotating rod 54, and a second connecting rod 55. The pedal 51 is rotatably connected to the lower part of the support frame 1. The first telescopic spring 52 is connected to both the left and right sides of the bottom wall of the pedal 51. The bottom ends of the first telescopic spring 52 are connected to the support frame 1. The first connecting rod 53 is rotatably connected to the right side of the pedal 51. The first rotating rod 54 is rotatably connected to the first connecting rod 53. The second connecting rod 55 is rotatably connected to the first connecting rod 53. The first rotating rod 54 is also rotatably connected to the upper part of the second connecting rod 55. The upper first rotating rod 54 is connected to the upper rotating frame 2, and the lower first rotating rod 54 is connected to the lower rotating frame 2.

[0041] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the unfolding mechanism 6 includes a fixed plate 61 and a first fixed block 62. The left and right sides of the support frame 1 are symmetrically welded with fixed plates 61. Each fixed plate 61 has two guide grooves 63. The left and right sides of the sliding frame 4 are fixed with first fixed blocks 62. Each first fixed block 62 corresponds to a guide groove 63. The first fixed blocks 62 slide in the corresponding guide grooves 63.

[0042] Initially, both the storage rack 3 and the sliding rack 4 are tilted forward to prevent dust from falling onto the books and periodicals. Each storage rack 3 and sliding rack 4 contains designated books and periodicals. When someone needs to retrieve or place books or periodicals, they first step on the front of the pedal 51. This compresses the first telescopic spring 52, causing the rear of the pedal 51 to rotate upwards, thus lifting the first connecting rod 53. This, in turn, causes the lower first rotating rod 54 to rotate clockwise, which in turn causes the lower rotating frame 2 to rotate clockwise. The first connecting rod 53 then lifts the second connecting rod 55, causing the upper first rotating rod 54 to rotate clockwise, which in turn causes the upper rotating frame 2 to rotate clockwise. The clockwise rotation of both rotating frames 2 causes the upper and lower storage racks 3 and sliding rack 4 to rotate clockwise to the designated angles. At this point, people can retrieve or place books and periodicals without manually rotating the storage racks 3 and sliding rack 4, saving manpower. The clockwise rotation of the storage racks 3 and sliding rack 4 also causes the first fixing block 62 to rotate clockwise, making... The first fixed block 62 slides along the guide groove 63, thereby lifting the upper and lower sliding frames 4, causing the upper and lower sliding frames 4 to slide upwards. This drives the books and periodicals inside the upper and lower sliding frames 4 to move upwards in a progressive manner, so that the books and periodicals in both the upper and lower parts are placed in a progressive manner, making it easier to see the titles of the books and periodicals and to find the books and periodicals needed. When people do not need to pick up or put down the books and periodicals, the pedal 51 is released, and the first telescopic spring 52 returns to its original position and lifts the front part of the pedal 51 upwards, so that the rear part of the pedal 51 rotates downwards. Then, through the first connecting rod 53, the first rotating rod 54 rotates counterclockwise, which in turn drives the lower rotating frame 2 to rotate counterclockwise. The first connecting rod 53 drives the upper first rotating rod 54 to rotate counterclockwise through the second connecting rod 55, which in turn drives the upper rotating frame 2 to rotate counterclockwise. The counterclockwise rotation of the upper and lower rotating frames 2 respectively drives the upper and lower storage racks 3 and sliding frames 4 to rotate counterclockwise to their original positions, thereby driving the books and periodicals to rotate counterclockwise to their original positions.

[0043] Example 2

[0044] Based on Example 1, such as Figure 1 , Figure 7 , Figure 8 and Figure 9As shown, it also includes a lighting mechanism 7, which includes a third connecting rod 71, a second rotating rod 72, a rotating disk 73, a fourth connecting rod 74, a third rotating rod 75, a rotating shaft 76, a torsion spring 77, and a lighting lamp 78. The third connecting rod 71 is rotatably connected to the upper first rotating rod 54, and the second rotating rod 72 is rotatably connected to the upper right side of the support frame 1. The second rotating rod 72 is rotatably connected to the third connecting rod 71, and the second rotating rod 72 passes through the right side of the inner wall of the support frame 1. 2. A rotating disk 73 is fixed to the left end. The rotating disk 73 is eccentrically connected to a fourth connecting rod 74. A third rotating rod 75 is rotatably connected to the fourth connecting rod 74. A rotating shaft 76 is rotatably connected to the upper right side of the support frame 1. The third rotating rod 75 is connected to the rotating shaft 76. A lighting lamp 78 is rotatably connected to the inner top wall of the support frame 1. The lighting lamp 78 is connected to the left end of the rotating shaft 76. A torsion spring 77 is wound on the rotating shaft 76. The left and right ends of the torsion spring 77 are connected to the support frame 1 and the rotating shaft 76, respectively.

[0045] When the library is dimly lit, the lighting 78 is turned on to provide illumination. When the first rotating rod 54 at the top rotates, it drives the second rotating rod 72 to rotate via the third connecting rod 71, which in turn drives the rotating disk 73 to rotate. This, in turn, drives the third rotating rod 75 to rotate via the fourth connecting rod 74, which in turn drives the rotating shaft 76 to rotate. The rotation of the rotating shaft 76 drives the lighting 78 to rotate. At this time, the torsion spring 77 undergoes torsional deformation. The rotation of the lighting 78 expands the illumination area, making it easier for people to find books and periodicals when the library is dimly lit. When it is not necessary to find books and periodicals, the lighting 78 is turned off.

[0046] like Figure 1 , Figure 10 and Figure 11 As shown, it also includes a sorting mechanism 8, which includes a locking tooth 81, a sliding member 82, a first buckle 83, and a second telescopic spring 84. The front side of the storage rack 3 is welded with locking teeth 81, and the front side of the storage rack 3 is slidably connected to the sliding member 82. The sliding member 82 is slidably connected to the locking tooth 81, and the first buckle 83 is slidably connected to the sliding member 82. The first buckle 83 can be locked onto the locking tooth 81 when it slides inward. The second telescopic spring 84 is wound around the first buckle 83, and the inner and outer ends of the second telescopic spring 84 are respectively connected to the first buckle 83 and the sliding member 82.

[0047] Initially, the first buckle 83 is engaged with the tooth 81. When different sizes of books and periodicals need to be placed in the front of the storage rack 3, people pull the first buckle 83 outward, causing it to slide outward and disengage from the tooth 81. At this time, the second telescopic spring 84 is compressed. Then, the slider 82 is pulled left and right, causing it to slide to the designated position, thereby dividing the space in the front of the storage rack 3 into three spaces. These three spaces can accommodate different sizes of books and periodicals, thus meeting the needs of placing different sizes of books and periodicals and having strong applicability. Afterward, the first buckle 83 is released, and the second telescopic spring 84 returns to its original position, causing the first buckle 83 to slide inward and engage with the tooth 81. Then, people can put different sizes of books and periodicals into the divided spaces.

[0048] like Figure 1 , Figure 12 and Figure 13 As shown, it also includes a clamping mechanism 9, which includes a rotating chuck 91, a rotating buckle 92, and a second fixing block 93. The rotating chuck 91 is rotatably connected to the lower part of the support frame 1. The top of the rotating chuck 91 is higher in the front and lower in the back. The rotating buckle 92 is rotatably connected to the lower left side of the front of the support frame 1. The rotating buckle 92 engages with the rotating chuck 91. The second fixing block 93 is welded to the bottom wall of the pedal 51. The rotating chuck 91 rotates 180 degrees and contacts the second fixing block 93.

[0049] Initially, the rotating buckle 92 engages with the rotating chuck 91, with the top of the rotating chuck 91 being higher in the front and lower in the back. When the pedal 51 is not needed, the rotating buckle 92 is rotated counterclockwise, causing it to disengage from the rotating chuck 91. Then, the rotating chuck 91 is rotated clockwise, causing it to rotate 180 degrees clockwise and contact the second fixing block 93. At this point, the top of the rotating chuck 92 is lower in the front and higher in the back, thus supporting the bottom of the pedal 51 and preventing books from accidentally being knocked out when the pedal 51 is stepped on, ensuring stable storage of the books. When the pedal 51 needs to be stepped on, the rotating chuck 91 is rotated counterclockwise, causing it to rotate 180 degrees counterclockwise and disengage from the second fixing block 93. Then, the rotating buckle 92 is rotated clockwise, causing it to rotate clockwise until it engages with the rotating chuck 91.

[0050] like Figure 1 , Figure 14 , Figure 15 and Figure 16As shown, it also includes a prompting mechanism 10, which includes a fixing member 101, a glass plate 102, a second buckle 103, and a tension spring 104. The front wall of the storage rack 3 is welded with the fixing member 101. The left and right sides of the front of the fixing member 101 are slidably connected to the second buckle 103. The front side of the fixing member 101 is slidably connected to the glass plate 102. The second buckle 103 holds the left and right sides of the glass plate 102. The second buckle 104 is wound around the second buckle 103. The inner and outer ends of the tension spring 104 are respectively connected to the fixing member 101 and the second buckle 103.

[0051] Initially, the two second latches 103 are secured to the left and right sides of the glass plate 102. To further facilitate the search for books and periodicals, a prompt card is first made, and the specific location of each book and periodical is marked on the prompt card. Then, the glass plate 102 is pulled forward, causing the second latches 103 to slide forward. At this time, the tension spring 104 is stretched. Then, the prompt card is placed inside the glass plate 102. Then, the glass plate 102 is released, and the tension spring 104 returns to its original position, causing the glass plate 102 to slide backward. This causes the second latches 103 to slide backward to their original position, thus completing the placement of the prompt card. After that, people can view the specific location of each book and periodical in real time through the glass plate 102, which further facilitates the search for books and periodicals and saves people's time in searching for books and periodicals.

[0052] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
