DETAILED DESCRIPTION
[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are used only for explaining the utility model, and cannot be understood as limiting the utility model.
[0027] In this embodiment:
[0028] A loose-leaf teaching material frame, such as Figures 1-5As shown, it includes a bottom protective plate 1 and a punch box 8. The punch box 8 is fixed to one side of the top of the bottom protective plate 1, and a pressing block 10 is slidably arranged inside the punch box 8. A connecting strip 11 is fixed to the bottom of the pressing block 10, and sliders 12 are fixed to both sides of the connecting strip 11 and engage with the punch box 8. Several sets of punching knives 13 are evenly spaced at the bottom of the connecting strip 11. A pad 16 is fixed to one side of the top of the bottom protective plate 1 and inside the punch box 8, and a limit post 14 is provided at both ends of the pad 16. The two ends of the limit post 14 are fixed to the bottom protective plate 1 and the punch box 8 respectively, and engage with the connecting strip 11 and slide together. A spring 15 is sleeved on the outside of the connecting strip 11.
[0029] In this process, the user simply places the new material on the pad 16 and then presses down on the pressing block 10. The connecting strip 11 will then move steadily downward under the guidance of the slider 12 and the limiting post 14. During this process, the punch 13 at the bottom of the connecting strip 11 will precisely punch holes in the material. The sleeve design of the spring 15 allows the connecting strip 11 to quickly return to its original position after punching, preparing it for the next punching operation.
[0030] See Figure 1 , Figure 2 and Figure 3 A side protective plate 3 is connected to the side of the bottom protective plate 1 away from the punch box 8, and a first crease 2 is provided at the connection between the bottom protective plate 1 and the side protective plate 3;
[0031] The design of the first crease 2 allows the side protective plate 3 to be easily folded or unfolded relative to the bottom protective plate 1, thus facilitating user adjustment as needed.
[0032] See Figure 2 and Figure 3 The top of the side protection plate 3 is provided with several sets of hinge rings 6 at equal intervals, and the hinge rings 6 and the punching knife 13 are arranged in a one-to-one correspondence.
[0033] The corresponding settings of the ring binder 6 and the hole punch 13 ensure that the punched documents can be perfectly fitted into the ring binder without any mismatch in hole size, which improves the convenience and satisfaction of users during use and makes document organization simpler and more efficient.
[0034] See Figure 1 , Figure 2 and Figure 3 A top protective plate 5 is installed on the side of the side protective plate 3 away from the bottom protective plate 1, and a second crease 4 is provided at the connection between the side protective plate 3 and the top protective plate 5.
[0035] The second crease 4 allows the top protective plate 5 to be folded relative to the side protective plate 3, so that the entire frame can be more compactly stored and carried. When the user needs to view or organize the teaching materials, the top protective plate 5 can be unfolded along the second crease 4 to form an open workspace. When not in use, the top protective plate can be easily folded to save space and protect the internal teaching materials from damage.
[0036] Referring to Figure 2 and Figure 3 , the top side of the top protective plate 5 is fixed with two groups of magnetic sheets 7;
[0037] The magnetic sheets 7 can interact with the magnetic material provided in the punch box 8 or other corresponding positions to form a strong magnetic attraction, thereby ensuring that the top protective plate 5 can be tightly closed and not easily opened accidentally.
[0038] Referring to Figure 1 , Figure 2 and Figure 3 Figure 2 Figure 3 Figure 1 Figure 2 Figure 3 , the top of the punch box 8 is fixed with two groups of support iron blocks 9, which are respectively arranged one by one corresponding to the two groups of magnetic sheets 7, and the two groups of support iron blocks 9 and the two groups of magnetic sheets 7 are attracted and attached;
[0039] When the top protective plate 5 is closed, the magnetic sheets 7 and the support iron blocks 9 are tightly attracted and attached, forming a strong magnetic connection, thereby ensuring that the teaching frame remains tightly closed during carrying or storage.
[0040] The implementation principle of the embodiment is as follows: first, place the bottom protective plate 1 in a suitable position, then hold the top protective plate 5 to separate the magnetic sheets 7 on the top protective plate 5 from the support iron blocks 9 on the top of the punch box 8, so that the top protective plate 5 and the side protective plate 3 can be unfolded and laid flat through the second crease 4 and the first crease 2. The multiple groups of ring binders 6 on the side protective plate 3 can be used to install teaching materials, and the ring binders 6 can be opened to replace the teaching materials. When new materials are needed, place the new materials on top of the pad 16, and then press the pressing block 10 downward to move the connecting strip 11 downward. The connecting strip 11 provides better stability through sliding and limiting of the two groups of limiting columns 14 and the two side sliding blocks 12. Then the punch knife 13 at the bottom of the connecting strip 11 punches holes in the materials above the pad 16. After punching, release the pressing block 10, and the spring 15 outside the limiting column 14 pushes the connecting strip 11 to reset. Finally, open the ring binder 6 to collect the punched materials.
[0041] Although the embodiments of the utility model have been shown and described, the specific embodiments are only the explanation of the utility model, and are not the limitation of the utility model, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable way, the person skilled in the art can make the modification, replacement and change of no creative contribution to the embodiment according to the need after reading the specification without departing from the principle and the purpose of the utility model, but as long as in the patent right claim range of the utility model, it is protected by the patent law.
