Description

Technical Field

[0001] This utility model relates to the field of desk technology, and in particular to a stepless adjustable bookshelf for a desk. Background Technology

[0002] Currently, the desks used by primary and secondary school students, such as those manufactured according to the national standard GB / T3976, have books laid flat on the table during class. Students need to lower their heads or tilt their eyes to see the contents of the books and textbooks smoothly, which can easily cause adverse problems such as hunchback, myopia, and strabismus for primary and secondary school students who are still growing.

[0003] As disclosed in announcement number CN217658658U, a folding book support for a school desk includes a base plate, a middle plate, and a book support board. The base plate is hinged to the middle plate, and the middle plate is hinged to the book support board. The book support has two states: open and folded. When the book support is open, the angle between the book support board and the base plate is an obtuse angle. When the book support is folded, the base plate, the middle plate, and the book support board are folded together. A support plate is provided at the bottom of the book support board or at the front of the middle plate. A central book clip is installed in the middle of the support plate and / or side book clips are installed on the left and right sides of the book support board.

[0004] However, this structure has many components and is relatively complex for existing desks, resulting in relatively high manufacturing costs. In addition, this structure occupies a large space and cannot be used with existing desks, which limits its use. Utility Model Content

[0005] To address the aforementioned issues, this utility model aims to provide a steplessly adjustable bookshelf for a desk, which facilitates the raising and lowering of the bookshelf and is highly versatile, compatible with existing common desk desktops.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0026] Combination Figures 1 to 6 As shown, this utility model discloses a stepless adjustable bookshelf for a desk, including a desktop 100, and a bookshelf 200 is provided on one side of the desktop 100. The bookshelf 200 is used to support the back of the book, so that the book can be in an upright position for students to read.

[0027] In this embodiment, a stepless adjustment component 300 is preferably used. The stepless adjustment component 300 includes a bookshelf mounting base 310, a bookshelf mounting part 320, and a limitless positioning mechanism 330. The bookshelf 200 is installed in conjunction with the bookshelf mounting part 320 and can move up and down along the bookshelf mounting part 320. The limitless positioning mechanism 330 is used to limit the position height of the bookshelf 200. By utilizing the structure of the stepless adjustment component 300, the height of the bookshelf 200 can be adjusted at will, improving the usability of the bookshelf 200. At the same time, the bookshelf 200 can be folded up to form an unobstructed structure, improving the cleanliness of the desktop 100 surface and enhancing the usability.

[0028] In the specific structure, the bookshelf mounting part 320 is provided with a bookshelf sleeve 321. The bookshelf stop 200 includes an upper stop bar 220 and lifting rods 210 located on both sides of the upper stop bar 220. The two lifting rods 210 are respectively sleeved in the bookshelf sleeves 321 in the two stepless adjustment components 300. The bookshelf sleeve 321 is a round tube structure. The lifting rods 210 are embedded in the inner cavity of the bookshelf sleeve 321 and can slide up and down along the bookshelf sleeve 321. The bookshelf mounting part 320 can also be other structures, such as a semi-circular ring.

[0029] In summary, the limitless positioning mechanism 330 includes a limiting base 331, a mounting base 334, and a limiting ball 333. The mounting base 334 is mounted on the limiting base 331, and a portion of the mounting base 334 protrudes outward from the side wall of the limiting base 331. The protruding portion of the mounting base 334 is used to correspond and cooperate with the third through hole 303 in the bookshelf mounting base 310. The limiting ball 333 is fitted inside the mounting base 332. The bookshelf sleeve 321 is provided with a first through hole 301, and the limiting ball 333... 33 can penetrate through the first through hole 301 and abut against the side wall of the lifting rod 210; when the lifting rod 210 needs to be raised or lowered, the user usually presses down or pulls up the lifting rod, and uses the rolling friction between the side wall of the lifting rod 210 and the limiting ball 333 to achieve the lifting; when the user does not exert any external force, the side wall of the lifting rod 210 is restricted by the abutment of the limiting ball 333, forming an abutment, so that the lifting rod 210 can be subjected to a lateral force, and the lifting rod 210 can be stationary.

[0030] In conjunction with the above, the mounting base 334 is provided with a receiving cavity 335, and a resisting spring 332 is provided in the receiving cavity 335. The resisting spring 332 is used to resist the limiting ball 333, and the limiting ball 333 can be accommodated in the receiving cavity 335. The resisting spring 332 is optimized so that the limiting ball 333 is subjected to force to resist, increasing the resistance force on the side wall of the lifting rod 210, and improving the smoothness and stability of the stepless adjustment.

[0031] In conjunction with the above, the mounting base 334 is provided with a second through hole 302, the inner diameter of the second through hole 302 is smaller than the diameter of the limiting ball 333, and the bookshelf mounting base 310 is provided with a third through hole 303. The first through hole 301, the second through hole 302 and the third through hole 302 are arranged in a corresponding manner to facilitate the contact and engagement between the limiting ball 333 and the side wall of the lifting rod 210.

[0032] In one preferred embodiment, a mounting groove 120 is provided on the side wall of the desktop 100, and a bookshelf mounting base 310 is fixedly installed in the mounting groove 120. The bookshelf mounting base 310 extends downward, and a limiting base 331 is fixedly installed on the inner side wall of the extension of the bookshelf mounting base 310. A limiting part 201 is provided at the bottom end of the lifting rod 210. The outer diameter of the limiting part 201 is larger than the inner diameter of the bookshelf sleeve 321 to prevent the lifting rod 210 from detaching when it is raised.

[0033] In one preferred embodiment, a book slot 110 is provided on the desktop 100, which is adjacent to the bookshelf 200 for convenient book placement.

[0034] This utility model features an optimized design, incorporating a stepless adjustment component for easy vertical adjustment of the bookshelf, allowing for free height adjustment to support books of different sizes. The optimized bookshelf mounting base structure facilitates easy and universal installation on existing desktops, enhancing the product's versatility.

[0035] In summary, it features a simple structure, convenient installation, and strong applicability.

[0036] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
