Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0028] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0029] Example 1

[0030] This utility model provides a notebook with detachable inner pages, such as... Figure 1As shown, it includes: a cover shell 1, which includes an upper cover panel 101, a side cover panel 102, and a lower cover panel 103; the upper cover panel 101, the side cover panel 102, and the lower cover panel 103 are sequentially flipped and connected, that is, the cover shell 1 adopts a continuous flipping connection structure in the prior art, ensuring that it can be flipped like a normal book or notebook, that is, both the upper cover panel 101 and the lower cover panel 103 can rotate freely; a row of binding posts 104 is fixed on the inner surface of the lower cover panel 103; a first connecting mating part 105 and a second connecting mating part 106 are respectively provided at both ends of the outer surface of the lower cover panel 103 along its length direction; a loose-leaf set 2, the loose-leaf set 2 having a loose-leaf set along one edge of it. There are paper holes 201 corresponding to the positions of the binding posts 104. The diameter of each paper hole 201 is in clearance fit with the outer diameter of the binding posts 104, so that the loose-leaf bundle 2 can be freely inserted into the binding posts 104 to form neatly stacked papers. The tightening band 3 has mounting holes 301 on its surface corresponding to the positions of the binding posts 104, so that the binding posts 104 can pass through. The tightening band 3 has a first connecting part 302 and a second connecting part 303 at both ends. The first connecting part 302 and the first connecting mating part 105 form a detachable fixed connection. The second connecting part 303 passes over the top of the loose-leaf bundle 2 and forms a detachable fixed connection with the second connecting mating part 106 to tighten the loose-leaf bundle 2.

[0031] Regarding the tension strap 3: The tension strap 3 is made of a soft material, such as nylon or other durable and strong fabric, but its elasticity should not be too great; when the first connecting part 105 and the second connecting part 106 are both hook and loop fasteners, the first connecting part 302 and the second connecting part 303 are both loop fasteners. The hook and loop fasteners are bonded together, allowing the tension strap 3 to be quickly removed, thereby allowing the loose pages in the loose-leaf assembly 2 to be removed; of course, the first connecting part 105 and the second connecting part 106 can also be set as snap fasteners, in which case the first connecting part 302 and the second connecting part 303 can be set as snap fastener caps.

[0032] The specific operations for disassembling and tightening the loose-leaf assembly 2 are as follows: 1. Tightening the loose-leaf assembly 2: After stacking the loose-leaf assembly 2 onto the lower cover panel 103 via the binding post 104, press and fix the first connecting part 302 of the tightening strap 3 onto the first connecting mating part 105. Then, insert the mounting hole 301 of the tightening strap 3 onto the binding post 104. Then, tighten the second connecting part 303 and press it firmly until the second connecting part 303 adheres to the second connecting mating part 106. 2. Disassembling the loose-leaf assembly 2: Pinch the second connecting part 303 of the tightening strap 3 firmly and lift it outwards to separate the second connecting part 303 from the second connecting mating part 106. Then, continue to lift the second connecting part 303 of the tightening strap 3 upwards to disengage the mounting hole 301 of the tightening strap 3 from the binding post 104. At this point, each loose-leaf page of the loose-leaf assembly 2 can be removed without much effort.

[0033] like Figure 4 As shown, a metal sheet 108 is fixed to the inner surface of the lower cover panel 103; the binding post 104 is fixed to the bearing surface of the metal sheet 108, thereby providing support for the binding post 104. The lower cover panel 103 also includes a plurality of rivets 109; the plurality of rivets 109 pass through the lower cover panel 103 and the metal sheet 108 in sequence, and rivet the two together.

[0034] like Figure 5 As shown, a metal groove 110 is fixed on the inner surface of the top cover panel 101. The metal groove 110 engages with the axial end of the binding post 104, which prevents the axial end of the binding post 104 from squeezing the top cover panel 101 and damaging the inner surface of the top cover panel 101, thus making it unsightly. Of course, in another solution, the metal groove 110 can be directly replaced by opening a hole on the inner surface of the top cover panel 101 to allow the axial end of the binding post 104 to pass through. This can avoid a large gap between the loose-leaf assembly 2 and the top cover panel 101 when the loose-leaf assembly 2 is thin. In this case, stacking the book binding posts 104 on the outer surface of the top cover panel 101 will put great pressure on the top cover panel 101 and damage it.

[0035] Example 2

[0036] Based on the above embodiment one, as follows Figure 7 As shown, the drawstring 3 is fixed with multiple counterweights 304. The counterweights 304 exert pressure on the loose-leaf assembly 2 to tighten it. The counterweights 304 are offset from the mounting holes 301 to ensure stable pressure on the loose-leaf assembly 2. The counterweights 304 can be made of metal, such as steel, or stone. Each counterweight 304 has a through hole 305 through which a thin thread is threaded to sew it to the drawstring 3. The drawstring 3 has a double-layer structure, such as a sealed, hollow bag structure. The counterweights 304 are fixed between the hollow double layers of the drawstring 3, making the outer surface of the drawstring 3 appear cleaner. Furthermore, the counterweight 304 is a magnetic sheet; an iron sheet is fixed on the inner surface of the lower cover panel 103; the iron sheet and the magnetic sheet are attracted to each other, which further increases the pressing effect of the counterweight 304 on the loose-leaf group 2; at this time, the loose-leaf group 2 can be made a little thinner, and the pressing effect of the counterweight 304 on the loose-leaf group 2 will be better.

[0037] Example 3

[0038] Based on the above embodiment one or two, such as Figure 9As shown, a radial expansion portion 107 is provided at the axial end of the binding post 104. A metal ring 306 is embedded in the inner wall of the mounting hole 301. The metal ring 306 has a certain degree of elasticity. The inner surface of the metal ring 306 and the outer surface of the radial expansion portion 107 form an interference fit. The purpose of this arrangement is to ensure that when the loose-leaf assembly 2 is in normal use and has not been removed, the binding strap 3 effectively restricts the loose-leaf assembly 2 and prevents it from easily coming off the binding post 104. A smooth arc-shaped transition is provided at the corner of the radial expansion portion 107 so that the metal ring 306 can smoothly engage with the radial expansion portion 107 and smoothly disengage from it when force is applied.

[0039] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
