Description

Technical Field

[0001] The utility model relates to the field of stationery, in particular to a book clamp. Background Art

[0002] In people's daily life, people are pursuing a free and convenient lifestyle and are used to studying in various places and venues. However, in the process of studying in various places, most of them need to hold books, but this will bring a poor learning experience. Therefore, products such as reading racks are now available to facilitate use in places such as beds, sofas, and floors to support books for easy study.

[0003] The Chinese utility model patent with the publication number CN219256859U discloses a concealable book pressing clip, which can install a mounting frame to the bottom of a table board, and the mounting frame can rotate relative to the table board. When the book pressing clip is not in use, the book pressing clip is stored under the table board to achieve a hidden effect. When the book pressing clip is used, the mounting frame is rotated to expose the rotating buckle assembly from the bottom of the table board, and then the rotating buckle assembly is rotated upward so that the rotating buckle assembly drives the book pressing rod to rotate upward, and the end of the book pressing rod away from the rotating buckle assembly can press the book on the table board. However, in the above technical solution, since the rotating buckle rotates around the axial direction perpendicular to the mounting frame, when the book is thick, the book will exert a large reaction force on the book pressing rod, especially when the wave surface of the sliding sleeve and the rotating buckle is in contact with the wave crest, the large force exerted by the book on the book pressing rod is likely to drive the rotating buckle assembly to rotate, resulting in the inability to clamp the book, affecting the user's experience.

[0004] The technical problem to be solved by the present application is: how to solve the problem that the existing book clamps have low stability in clamping thick books, thus affecting the user experience. Utility Model Content

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] See also Figures 1 to 3 , which is a book pressing clamp 100 of a preferred embodiment of the utility model, includes a fixed part 10 and a rotating part 20, the fixed part 10 includes a fixed rod 11 and a rotating shaft 12 connected to one end of the fixed rod 11, the central axis of the rotating shaft 12 is arranged parallel to the central axis of the fixed rod 11, and the end of the fixed rod 11 close to the rotating shaft 12 is provided with a first meshing surface 111, the rotating part 20 includes a rotating seat 21 on which the rotating shaft 12 is sleeved, an elastic member 22 and an adjusting screw 23 built into the rotating seat 21, and an elastic pressure rod 24 connected to the rotating seat 21, and the rotating seat 21 is provided with a second meshing surface 211 meshing with the first meshing surface 111 at one end of the rotating seat 21 close to the fixed rod 11, and a accommodating cavity for accommodating the elastic member 22 and the adjusting screw 23 is provided inside the rotating seat 21, the adjusting screw 23 is threadedly connected to the rotating shaft 12, the elastic member 22 is sleeved on the rotating shaft 12, and the two ends of the elastic member 22 respectively abut the bottom of the accommodating cavity and the head of the adjusting screw 23. The book press 100 of the present application sets the central axis of the rotating shaft 12 to be parallel to the central axis of the fixing rod 11, and the rotating seat 21 is sleeved on the outer surface of the rotating shaft 12 and rotates around the central axis of the rotating shaft 12. The advantage of such a setting is that even if the elastic pressure rod 24 is subjected to a reaction force when clamping a book, the elastic pressure rod 24 will not drive the rotating seat 21 to rotate, which greatly improves the stability of the book press 100 in clamping a book and improves the user experience.

[0034] like Figure 3 As shown, in this embodiment, the first meshing surface 111 and the second meshing surface 211 are corresponding meshing wavy surfaces. In other embodiments, the first meshing surface 111 and the second meshing surface 211 can also be set to have convex teeth arranged at uniform intervals. The advantage of such a setting is that when the convex teeth on the first meshing surface 111 are meshed with the tooth grooves on the second meshing surface 211, the first meshing surface 111 and the second meshing surface 211 are self-locking. When the external force driving the rotating seat 21 to rotate is greater than the pressure applied by the elastic member 22, the rotating seat 21 can rotate relative to the fixed rod 11. The rotation accuracy of the rotating seat 21 can be determined according to the density of the convex teeth, and the spacing of the convex teeth can be set according to actual needs.

[0035] In this embodiment, the elastic member 22 is a compression coil spring. In other embodiments, the elastic member 22 may also be elastic silicone or rubber, spring sheet or other elastic bodies that can achieve the same function.

[0036] Preferably, the fixing rod 11 and the rotating shaft 12 are integrally formed.

[0037] Furthermore, if Figure 2 As shown, a groove 112 is provided at one end of the fixing rod 11 close to the rotating shaft 12, a first meshing surface 111 is provided at the bottom of the groove 112, a convex column 212 is provided at one end of the rotating seat 21 close to the fixing rod 11 to be inserted into the groove 112, and a top of the convex column 212 is provided at the second meshing surface 211. Through the cooperation between the groove 112 and the convex column 212, the first meshing surface 111 and the second meshing surface 211 can be hidden, which makes the book clip 100 more beautiful on the one hand, and prevents foreign matter from entering between the first meshing surface 111 and the second meshing surface 211 and affecting the normal operation of the rotating seat 21 on the other hand.

[0038] like Figure 2 As shown, in order to facilitate the installation of the elastic pressure rod 24 and to cover the adjusting screw 23, the rotating part 20 further includes a mounting block 25, which is detachably arranged at one end of the accommodating cavity away from the second meshing surface 211, and the elastic pressure rod 24 is connected to the mounting block 25.
