Description

Technical Field

[0001] The utility model relates to the technical field of bookshelves, in particular to a high-strength, wear-resistant and multifunctional bookshelf. Background Art

[0002] The most basic function of a bookshelf is to provide storage and organization space. People use it to store books, magazines, folders, documents, and other items, keeping the space clean and orderly. Furthermore, a bookshelf can also serve as a study and research space, with a desk or chair placed next to it, allowing readers to better focus and conduct in-depth study and research. Most bookshelves are assembled structures, and prolonged access to books will cause contact with the bookshelf itself, causing the structure to loosen, resulting in shaking and structural instability, which in turn affects the shelf's lifespan. Utility Model Content

[0003] The purpose of the utility model is to provide a high-strength, wear-resistant, multifunctional bookshelf to solve the above problems.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-strength, wear-resistant, multifunctional bookshelf, comprising:

[0005] A bookshelf assembly, comprising a bookshelf support plate, a connecting rod A, a side plate, and a card cover;

[0006] There are multiple bookshelf support plates, with a spacing between every two bookshelf support plates, and multiple integrally fixed connecting blocks A are provided at both ends of each bookshelf support plate, and one end of each connecting block A is hinged to a connecting rod A;

[0007] There are multiple side plates, and two card covers are arranged between every two side plates. The upper and lower ends of the card covers are fixedly connected to the two side plates respectively, and every two card covers are sleeved on the outside of the two connecting rods A.

[0008] Preferably, an integrally fixed limit block is provided on the outer side of each connecting rod A, and the limit block is stuck in the end of the card cover. If the structure becomes loose, the tightness of the side panel can be adjusted by adjusting the position of the nut, thereby improving the strength of the bookshelf through the buckling method of the reaction force.

[0009] Preferably, threaded rods are symmetrically provided at both ends of the bookshelf support plate, a sleeve is provided on the outer side of the threaded rod, and connecting blocks B are provided on both sides of the sleeve, and a connecting rod B is provided at one end of the connecting rod A, and the two ends of the connecting rod B are hinged to the connecting rod A and the connecting block B respectively.

[0010] Preferably, a nut is sleeved on the outer side of the threaded rod, the nut is threadedly connected to the threaded rod, one end of the sleeve is sleeved on the outer side of the nut, and the nut is rotatably connected to the sleeve.

[0011] Preferably, a baffle is provided on one side of the bookshelf support plate, the baffle is perpendicular to the bookshelf support plate, and the baffle and the bookshelf support plate are an integrated fixed structure. The baffle and the bookshelf support plate cooperate with each other to form an angle, forming a slot when placing books, thereby reducing the risk of books falling off.

[0012] Preferably, the top and bottom of the bookshelf support plate are both provided with an embedded wear-resistant layer, and the wear resistance is improved by the wear-resistant layer shell on the bookshelf support plate. The wear-resistant layer is made of metal and has good wear resistance.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. Connecting rod B pulls connecting rod A to rotate, reducing the distance between the ends of the two connecting rods A. At this time, put the card cover on the outside of the connecting rod A and rotate the nut in the opposite direction, so that the sleeve pushes the connecting rod B to move to the outside of the threaded rod, thereby increasing the distance between the ends of the connecting rod A. The reaction force generated by the connecting rod A pushes the limit block to lock tightly at the end of the card cover. If the structure becomes loose, simply adjust the position of the nut to adjust the tightness of the side panel.

[0015] 2. The strength of the bookshelf is improved by the interlocking method of the reaction force, and the wear resistance is improved by the wear-resistant layer shell on the bookshelf support plate. The wear-resistant layer is made of metal and has good wear resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figure 1-3 , the utility model provides a technical solution: a high-strength wear-resistant multifunctional bookshelf, including;

[0024] A bookshelf assembly, comprising a bookshelf support plate 100, a connecting rod A201, a side plate 400, and a card cover 401;

[0025] There are multiple bookshelf support plates 100, with a spacing between every two bookshelf support plates 100, and multiple integrally fixed connecting blocks A200 are provided at both ends of each bookshelf support plate 100, and one end of each connecting block A200 is hinged to a connecting rod A201;

[0026] There are multiple side panels 400 , and two card covers 401 are arranged between every two side panels 400 . The upper and lower ends of the card covers 401 are fixedly connected to the two side panels 400 , respectively. Every two card covers 401 are sleeved on the outside of two connecting rods A201 .

[0027] Furthermore, an integrally fixed limit block 202 is provided on the outer side of each connecting rod A201, and the limit block 202 is clamped at the end of the card cover 401. If the structure becomes loose, the tightness of the side panel 400 can be adjusted by adjusting the position of the nut 301, thereby improving the strength of the bookshelf through the interlocking method of the reaction force.

[0028] Furthermore, the two ends of the bookshelf support plate 100 are symmetrically provided with integrally fixed threaded rods 300, the outer side of the threaded rod 300 is sleeved with a sleeve 302, and both sides of the sleeve 302 are provided with integrally fixed connecting blocks B303, and one end of the connecting rod A201 is provided with a connecting rod B203, and the two ends of the connecting rod B203 are respectively hinged to the connecting rod A201 and the connecting block B303.

[0029] Furthermore, a nut 301 is sleeved on the outside of the threaded rod 300 , and the nut 301 is threadedly connected to the threaded rod 300 . One end of the sleeve 302 is sleeved on the outside of the nut 301 , and the nut 301 and the sleeve 302 are rotatably connected.

[0030] Furthermore, a baffle 101 is provided on one side of the bookshelf support plate 100. The baffle 101 is perpendicular to the bookshelf support plate 100, and the baffle 101 and the bookshelf support plate 100 are an integrated fixed structure. The baffle 101 and the bookshelf support plate 100 cooperate with each other to form an angle, forming a slot when placing books, thereby reducing the risk of books falling off.

[0031] Furthermore, the top and bottom of the bookshelf support plate 100 are both provided with an embedded wear-resistant layer 102, and the wear resistance is improved by the wear-resistant layer 102 shell on the bookshelf support plate 100. The wear-resistant layer 102 is made of metal and has good wear resistance.

[0032] Working principle: When in use, rotate the nut 301 so that the nut 301 is sleeved on the outside of the threaded rod 300 and slides horizontally, so that the nut 301 pulls the sleeve 302 to slide horizontally on the threaded rod 300, so that the connecting rod B203 pulls the connecting rod A201 to rotate, so that the distance between the ends of the two connecting rods A201 is reduced. At this time, the card cover 401 is sleeved on the outside of the connecting rod A201, and the nut 301 is rotated in the opposite direction so that the sleeve 302 pushes the connecting rod B203 toward the threaded rod. The outer side movement of 300 expands the spacing between the ends of the connecting rod A201, so that the reaction force generated by the connecting rod A201 pushes the limit block 202 to be locked tightly on the end of the card cover 401. If the structure becomes loose, it is only necessary to adjust the position of the nut 301 to adjust the tightness of the side panel 400. The strength of the bookshelf is improved by the buckling method of the reaction force, and the wear resistance is improved by the wear-resistant layer 102 shell on the bookshelf support plate 100. The wear-resistant layer 102 is made of metal and has good wear resistance.
