Description

Technical Field

[0001] The utility model relates to the technical field of book stands, in particular to a fixed book stand for books in a library. Background Art

[0002] Bookends are used to support books, keeping them upright. They are often made of materials like iron or stainless steel in an "L" shape and come in pairs. They prevent a row of books from tilting, bending, or being damaged. They can also be used to organize different types of books. For libraries with large collections of books, bookends are essential for organizing the shelves. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a fixed book stand for library books in view of the above shortcomings.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A library book fixing book stand comprises two L-shaped support plates, a guide shaft, a sleeve, a suction cup and a pressing handle. A positioning hole is provided in the middle of the horizontal plate of the L-shaped support plate, a suction cup is provided in the positioning hole, a sleeve is vertically provided on the suction cup, a guide shaft is vertically provided on the inner side of the sleeve, the upper end of the guide shaft passes through and extends to the top of the sleeve, the sleeve can slide up and down along the guide shaft, a pressing handle for pressing down and pushing the sleeve is hinged on the guide shaft, a plurality of L-shaped support rods passing through the sleeve are evenly distributed radially at the bottom of the guide shaft, the other ends of the plurality of L-shaped support rods are fixedly connected to the horizontal plate of the L-shaped support plate, and the L-shaped support rods are used to support and fix the guide shaft.

[0006] Furthermore, a spring located outside the guide shaft is sleeved on the inner side of the sleeve, and the upper and lower ends of the spring are in contact with the top wall of the inner cavity of the sleeve and the upper surface of the L-shaped support rod respectively.

[0007] Furthermore, an annular pressure plate is horizontally provided at the lower end edge of the sleeve, and the annular pressure plate is located inside the positioning hole and above the suction cup. The annular pressure plate is used to cooperate with the sleeve to squeeze the suction cup.

[0008] Furthermore, an annular anti-slip rubber strip for increasing friction is provided at the bottom of the L-shaped support plate.

[0009] Furthermore, a plurality of rectangular holes are uniformly opened in the radial direction on the sleeve, and the L-shaped support rod passes through the rectangular holes.

[0010] Furthermore, a support ring for supporting the multiple L-shaped support rods is provided on the horizontal arms of the multiple L-shaped support rods.

[0011] Furthermore, the pressing handle includes a protruding piece and a handle, wherein the protruding piece is rotatably connected to the guide shaft, and the handle is used to drive the protruding piece to rotate in a vertical plane to squeeze the sleeve.

[0012] Compared with the prior art, the present invention has the following advantages after adopting the above technical solution:

[0013] This new bookend offers fast fixation, strong stability, easy adjustment, a stable structure, ease of installation, and excellent anti-slip properties. Through the designed push-down handle, guide shaft, sleeve, and suction cup structure, the user simply presses down on the handle to quickly secure the bookend to an external surface such as a bookshelf or desk. The suction cup design enhances the suction force between the bookend and the surface, making it less likely to move and effectively preventing books from tilting due to an unstable bookend. By providing a circular anti-slip rubber strip at the bottom of the L-shaped support plate, the friction between the bookend and the surface is increased, further ensuring the stability and safety of the book.

[0014] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, they cannot be understood as limitations on the present invention.

[0023] like Figure 1-4 As shown, a fixed book stand for library books includes two L-shaped support plates 1, a guide shaft 2, a sleeve 3, a suction cup 4 and a pressing handle 5. A positioning hole 6 is opened in the middle of the horizontal plate of the L-shaped support plate 1, and a suction cup 4 is arranged in the positioning hole 6. A sleeve 3 is vertically arranged on the suction cup 4, and a guide shaft 2 is vertically arranged on the inner side of the sleeve 3, the upper end of which passes through and extends to the top of the sleeve 3. The sleeve 3 can slide up and down along the guide shaft 2, and a pressing handle 5 for pressing down and pushing the sleeve 3 is hinged on the guide shaft 2. A plurality of L-shaped support rods 7 passing through the sleeve 3 are evenly distributed radially on the bottom of the guide shaft 2, and the other ends of the plurality of L-shaped support rods 7 are fixedly connected to the horizontal plate of the L-shaped support plate 1, and the L-shaped support rods 7 are used to support and fix the guide shaft 2.

[0024] As an embodiment, a spring 8 located outside the guide shaft 2 is sleeved on the inner side of the sleeve 3 , and the upper and lower ends of the spring 8 are in contact with the inner cavity top wall of the sleeve 3 and the upper surface of the L-shaped support rod 7 respectively.

[0025] As an embodiment, an annular pressure plate 9 is horizontally provided at the lower end edge of the sleeve 3 , and the annular pressure plate 9 is located inside the positioning hole 6 and above the suction cup 4 . The annular pressure plate 9 is used to cooperate with the sleeve 3 to squeeze the suction cup 4 .

[0026] As an embodiment, an annular anti-slip rubber strip 10 for increasing friction is provided at the bottom of the L-shaped support plate 1 .

[0027] As an embodiment, a plurality of rectangular holes 11 are uniformly opened in the radial direction on the sleeve 3 , and the L-shaped support rod 7 passes through the rectangular holes 11 .

[0028] As an embodiment, a support ring 12 for supporting the multiple L-shaped support rods 7 is provided on the horizontal arms of the multiple L-shaped support rods 7 .

[0029] As an embodiment, the pressing handle 5 includes a protruding piece and a handle. The protruding piece is rotatably connected to the guide shaft 2 , and the handle is used to drive the protruding piece to rotate in a vertical plane to squeeze the sleeve 3 .

[0030] In the present invention, the material of the annular anti-slip rubber strip 10 is silicone, which can fit the placement surface well when subjected to pressure, and the extruded edge of the protrusion is an elliptical arc.

[0031] The present invention works as follows: First, place two bookends on a bookshelf or desk to be secured. Then, rotate the downward handle 5 of one of the bookends. Initially, the handle 5 is horizontal, and the suction cup 4 is not attached and located inside the positioning hole 6. As the handle 5 rotates horizontally, the elliptical extrusion edge of the protrusion gradually compresses the sleeve 3, pushing the sleeve 3 downward until the suction cup 4 at the bottom of the sleeve 3 makes firm contact with the placement surface. As the sleeve 3 is pressed downward, the spring 8 is compressed, forcing the air inside the suction cup 4 out, creating negative pressure, which secures the bookend to the placement surface. The spring 8 applies an upward force to the downward handle 5 through the sleeve 3, securing it. The L-shaped support rod 7 then applies a downward force to the L-shaped support plate 1, securing the first bookend. Books can then be neatly placed between the two bookends. The other bookend can then be pushed to clamp the books, and the downward handle 5 can be rotated to secure the bookend. If the user needs to adjust the position of the bookend during use, they simply reverse the downward handle 5 to release the suction cup 4, allowing the bookend to be easily moved. During use, the annular anti-skid rubber strip 10 increases friction when the bookshelf is fixed, thereby improving the stability of the bookshelf.

[0032] The above description is merely an example of the preferred embodiment of the present invention. Any details not described in detail are common knowledge within the art. The scope of protection of the present invention is determined by the claims. Any equivalent modifications based on the technical teachings of the present invention are also within the scope of protection of the present invention.
