The book baffle adopts the combination of the guide rail assembly and the traction assembly, so that the cover plate can slide horizontally, and the first baffle is driven to get close to or get away from the second baffle to adapt to books with different thicknesses. Meanwhile, due to the design of the fastener, the cover plate can be firmly locked after being adjusted in place, and books are prevented from toppling or sliding. In addition, the stability and the sliding smoothness of the device are further improved through the stepped table and boss structure between the base and the cover plate.

Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of learning aids, and particularly relates to an adjustable distance book blocking plate which can adjust the distance between the blocking plates according to the thickness of books or files. The device is suitable for office, learning, library and other scenes, and can effectively arrange and fix books or files on the desktop to prevent them from falling or scattering. BACKGROUND

[0002] In daily life and work, the arrangement and fixation of books, files or other paper materials is a common requirement. Especially in office desks, learning desks or libraries, the number of books and files is large and the thickness is different. The traditional fixation method (such as book stand or simple blocking plate) often cannot adapt to books of different thickness, resulting in books falling or scattering, affecting the use efficiency and the neatness of the desktop. In addition, the traditional book blocking plate is usually of fixed structure and cannot be adjusted according to the thickness of the books, so the flexibility of use is poor.

[0003] At present, there are some adjustable book blocking plates on the market, but their structures are complex, the adjustment method is cumbersome, and the stability is poor. For example, some book blocking plates adopt a manual adjustment method to adjust the distance between the blocking plates, which needs to be operated repeatedly by the user, and is inconvenient to use. Some book blocking plates adopt a spring or elastic element to realize automatic adjustment, but the structure design is unreasonable, which easily causes the blocking plate to tilt or slide smoothly, affecting the use effect.

[0004] In addition, the existing book blocking plate often lacks an effective locking mechanism when fixing books, so that the books are easily moved or fallen when subjected to external force.

[0005] In view of the above problems, it is urgent to design a blocking plate structure which can be automatically adjusted according to the thickness of books and files. CONTENT OF THE INVENTION

[0006] The application provides an adjustable distance book blocking plate to solve the problems of complex structure, cumbersome adjustment method and poor stability of the existing book blocking plate.

[0007] The application adopts the following technical scheme: an adjustable distance book blocking plate, comprising:

[0008] a base, which is horizontally placed on the desktop;

[0009] a cover plate, which is horizontally slidably arranged at the upper end of the base;

[0010] a first blocking plate, which is arranged at the upper end of the cover plate, and a second blocking plate, which is fixedly arranged at the other side of the base;

[0011] a traction assembly, which is arranged between the cover plate and the base, and is used to pull the first blocking plate close to the second blocking plate;

[0012] The fastener is arranged on one side of the cover plate to fix the position of the cover plate.

[0013] Further, the guide rail assembly includes a straight groove formed in the base.

[0014] Further, a sliding block is arranged in the straight groove, and the upper end of the sliding block is fixedly connected to the lower end of the cover plate.

[0015] Further, the traction assembly includes a traction groove formed in the base and a protrusion fixed to the lower end of the cover plate, and the traction groove is provided with a tension spring.

[0016] Further, the straight groove and the traction groove are arranged horizontally, and the extension directions of the straight groove and the traction groove are the same as the extension direction of the base.

[0017] Further, the opposite sides of the base are provided with stepped platforms, and the opposite sides of the cover plate are respectively provided with protrusions.

[0018] Further, the protrusions and the stepped platforms are adapted to each other in an up-down manner to maintain the horizontal coaxiality when the cover plate slides relative to the base.

[0019] Further, the fastener is a bolt arranged on the protrusion, and the bolt is pre-tightened with the stepped platform to fix the horizontal position of the cover plate.

[0020] Beneficial effects: The adjustable book stopping plate provided by the present application can automatically adjust and flexibly fix the distance between the stopping plates through the cooperative design of the base, the cover plate, the stopping plate, the traction assembly, and the fastener. The combination of the guide rail assembly and the traction assembly enables the cover plate to slide horizontally, thereby driving the first stopping plate to approach or move away from the second stopping plate to adapt to books of different thicknesses. Meanwhile, the design of the fastener ensures that the cover plate can be firmly locked after being adjusted in place, preventing the books from falling or sliding. In addition, the stepped platform and the protrusion structure between the base and the cover plate further improve the stability and smoothness of the device. The book stopping plate has a simple structure, a convenient adjustment mode, and high stability, and can effectively solve the problems of complex structure, tedious adjustment mode, and poor stability of existing book stopping plates, and has a wide application prospect.

[0037] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The features in the following examples can be combined with each other without conflict.

[0038] Example 1:

[0039] Please refer to Figures 1 to 4 As shown in the drawings, the present application provides an adjustable distance book stop, which aims to solve the problems of complex structure, cumbersome adjustment and poor stability of the existing book stop. The design of the book stop realizes automatic adjustment and flexible fixation of the distance between the book stops through the cooperation of the base 100, the cover plate 200, the book stop, the traction assembly 300 and the fastener 600, which is suitable for books of different thicknesses, while ensuring the stability and smoothness of the device.

[0040] The base 100 is the basic component of the whole book stopper, which is horizontally placed on the desktop to provide stable support for the device. The base 100 is made of high-strength material to ensure its durability and load-bearing capacity. The two side edges of the base 100 are provided with stepped platforms 110. The stepped platforms 110 not only enhance the rigidity of the base 100, but also provide a guiding effect for the sliding of the cover plate 200. The shape of the stepped platforms 110 is adapted to the boss 210 on the cover plate 200, so that the cover plate 200 can maintain horizontal coaxiality during sliding, avoiding tilting or deviation. The upper end of the base 100 is provided with a straight groove 510, which extends horizontally and has the same extension direction as the base 100. A sliding block 520 is slidably arranged in the straight groove 510, and the upper end of the sliding block 520 is fixedly connected to the lower end of the cover plate 200, so that the cover plate 200 can slide horizontally on the base 100. The design of the guide rail assembly 500 makes the sliding of the cover plate 200 more smooth, while ensuring the horizontal coaxiality between the cover plate 200 and the base 100.

[0041] As a preferred embodiment of the present embodiment, the cover plate 200 is horizontally slidably arranged at the upper end of the base 100. The two side edges of the cover plate 200 are respectively provided with bosses 210, which are adapted to the stepped platforms 110 on the base 100 in an up-down manner, so as to maintain the horizontal coaxiality of the cover plate 200 relative to the base 100 during sliding. The cooperation of the bosses 210 and the stepped platforms 110 not only improves the stability of the device, but also ensures that the cover plate 200 will not tilt or deviate during sliding. The upper end of the cover plate 200 is fixedly provided with a first baffle 400, and the other side of the base 100 is fixedly provided with a second baffle 410. The first baffle 400 and the second baffle 410 together constitute the main part of the book stopper for clamping books. By sliding the cover plate 200, the first baffle 400 can be close to or away from the second baffle 410, so as to adjust the distance of the book stopper to adapt to books of different thicknesses.

[0042] The traction assembly 300 is arranged between the cover plate 200 and the base 100, and is used to pull the first baffle 400 close to the second baffle 410. The traction assembly 300 includes a traction groove 310 fixedly arranged on the base 100, and a protrusion 320 fixedly arranged at the lower end of the cover plate 200. The protrusion 320 is provided with a tension spring 330 in the traction groove 310, one end of the tension spring 330 is fixed to the protrusion 320, and the other end is fixed to the end of the traction groove 310.

[0043] When the cover plate 200 slides, the tension spring 330 will generate a pulling force, so that the first baffle 400 automatically approaches the second baffle 410, thereby realizing the automatic adjustment of the distance between the book stopping plates. The traction groove 310 and the straight groove 510 are horizontally arranged, and their extension directions are the same as the extension direction of the base 100, which ensures the cooperation of the traction assembly 300 and the guide rail assembly 500. The design of the traction assembly 300 makes the adjustment process of the book stopping plates more convenient, and the user only needs to gently push the cover plate 200 to complete the adjustment of the distance.

[0044] As a preferred embodiment of the present embodiment, the fastener 600 is arranged on one side of the cover plate 200 for fixing the position of the cover plate 200. The fastener 600 is a bolt arranged on the boss 210, and the bolt is pre-tightened with the stepped table 110 to fix the horizontal position of the cover plate 200. After the distance of the book stopping plates is adjusted to the right position, the cover plate 200 can be firmly locked on the base 100 by tightening the bolt, preventing the books from falling or sliding. The design of the fastener 600 not only improves the stability of the book stopping plates, but also makes the adjustment process more flexible and convenient. The pre-tightening force of the bolt can be adjusted according to actual needs to ensure that the cover plate 200 can be firmly fixed in different use scenarios.

[0045] As a preferred embodiment of the present embodiment, the guide rail assembly 500 includes a straight groove 510 opened in the base 100 and a sliding block 520 slidingly arranged in the straight groove 510. The upper end of the sliding block 520 is fixedly connected to the lower end of the cover plate 200, so that the cover plate 200 can slide horizontally on the base 100. The design of the guide rail assembly 500 makes the sliding of the cover plate 200 more smooth, while ensuring the horizontal coaxiality between the cover plate 200 and the base 100. The straight groove 510 and the traction groove 310 are horizontally arranged, and their extension directions are the same as the extension direction of the base 100, which ensures the cooperation of the guide rail assembly 500 and the traction assembly 300. The guide rail assembly 500 has simple structure, easy to manufacture and install, and has high durability and stability.

[0046] The working principle of the book stopping plate is as follows:

[0050] 2. Adjust the distance: The user gently pushes the cover plate 200 horizontally on the base 100. The sliding of the cover plate 200 will bring the first stop plate 400 closer to or farther away from the second stop plate 410, thereby adjusting the distance of the book stop. The tension spring 330 in the traction assembly 300 will automatically generate tension, causing the first stop plate 400 to approach the second stop plate 410, thereby achieving automatic adjustment of the distance of the book stop.

[0051] 3. Fix the cover plate 200: When the distance of the book stop is adjusted to the right position, the user tightens the bolt on the fastener 600 to firmly lock the cover plate 200 on the base 100, preventing the books from falling or sliding. The pre-tightening force of the bolt can be adjusted according to actual needs to ensure that the cover plate 200 remains firmly fixed in different use scenarios.

[0052] 4. Take out the books: When the user needs to take out the books, they can simply loosen the bolt on the fastener 600 and gently push the cover plate 200, causing the first stop plate 400 to move away from the second stop plate 410, making it easy to take out the books.

[0053] The book stop in this application has the following advantages:

[0054] 1. Simple structure: The book stop has a simple structure, mainly composed of a base 100, a cover plate 200, a stop plate, a traction assembly 300, and a fastener 600, making it easy to manufacture and install.

[0055] 2. The adjustment is convenient, and the adjustment process of the book stop is very convenient. The user only needs to gently push the cover plate 200 to complete the adjustment of the distance. The tension spring 330 in the traction assembly 300 will automatically generate tension, causing the first book stop 400 to approach the second book stop 410, thereby achieving automatic adjustment of the distance between the book stops.

[0056] 3. The stability is high, and the combination of the guide rail assembly 500 and the traction assembly 300 makes the cover plate 200 horizontally slide, while ensuring the stability and reliability of the device. The design of the fastener 600 further improves the stability of the book stop, preventing the book from falling or sliding.

[0057] 4. The applicability is strong, and the book stop is suitable for books of different thicknesses. The user can flexibly adjust the distance of the book stop according to actual needs. The cooperative design of the guide rail assembly 500 and the traction assembly 300 makes the book stop adapt to various use scenarios.
