Abstract
Description
Technical Field
[0001] This utility model relates to the field of drawer folders, and more specifically, to a drawer folder. Background Technology
[0002] Stationery is very common in people's lives. When organizing and using loose book pages, drawer folders are often used. This involves stacking the book pages inside a plastic sheet and clamping one end of the plastic sheet and the book pages together with a drawer. This achieves the organization and binding of loose book pages. Existing drawer folders generally consist of a drawer and a plastic sheet. The area of the plastic sheet is fixed. When the area of the loose book pages is small, the area of the plastic sheet is larger than the area of the book pages, resulting in a lot of wasted space and affecting the browsing of the entire folder. In addition, after long-term use, the clamping ability of the two parts of the drawer will be affected by the deformation of the plastic itself, which may cause the clamping to be incomplete. Furthermore, when clamping a small number of book pages, if the thickness of the book pages is less than the gap of the drawer, the pages cannot be clamped, thus affecting the use of the entire folder.

[0015] (III) Beneficial Effects
[0016] Compared with the prior art, the present invention provides a drawstring folder, which has the following advantages:
[0017] 1. This utility model, by setting a first through groove on the drawer body, allows for adjustment of the usable area of the plastic sheet when one end of the plastic sheet with the first locking block is pulled, so that it passes through the first through groove on the drawer body. The first locking block engages with different first fixing holes on the drawer body, and the engagement of the first locking block with the first retaining ring fixes one end of the plastic sheet to the drawer body.

[0029] Please see Figure 1-5 A drawer folder includes a plastic sheet 1 and a drawer body 2. The plastic sheet 1 is detachably disposed inside the drawer body 2. The drawer body 2 is provided with a winding structure, which includes a first through groove 3 and a first fixing hole 4. The first through groove 3 and the plastic sheet 1 cooperate with each other, and the first fixing hole 4 is provided with multiple holes.
[0030] A filler plate 5 is detachably provided on the upper end of the draw rod body 2. Two sets of filler plates 5 are provided. A fixing structure is provided on the filler plate 5. The fixing structure includes a fixing block 6 and a mounting bracket 7. The mounting bracket 7 is provided on the filler plate 5. The fixing block 6 is detachably provided on the mounting bracket 7. A second passage groove 8 is provided on the draw rod body 2.
[0031] In this embodiment, the main structure of the entire drawer folder is composed of the drawer body 2, the filling plate 5, and the plastic sheet 1.
[0032] More specifically, the rewinding structure facilitates changes in the usable area of the plastic sheet 1, and the fixing structure facilitates the integration of thinner pages.
[0033] Please see Figures 1-5As one implementation method for using the entire folder: a first retaining ring 9 is fixedly installed in the first fixing hole 4, and multiple first retaining rings 9 are provided. A first retaining block 10 is fixedly installed on the plastic sheet 1. The first retaining rings 9 and the first retaining block 10 cooperate with each other and are engaged. Both ends of the draw rod body 2 are fixedly provided with protruding blocks 11, which cooperate with the filling plate 5. A second fixing hole 12 is opened on the protruding block 11 on one side of the draw rod body 2, and a mating groove 13 is opened on the protruding block 11 on the other side of the draw rod body 2. Multiple second fixing holes 12 are provided, and a second retaining ring 14 is installed in the second fixing hole 12. A second retaining block 15 is fixedly installed at one end of the filling plate 5, and the second retaining block 15 cooperates with the second retaining ring 14. The locking block 15 is engaged with the second locking ring 14. The other end of the filling plate 5 is provided with a mating block 16, which is fixedly connected to the filling plate 5. The mating block 16 and the mating groove 13 cooperate with each other. Multiple second through grooves 8 are provided, which cooperate with each other and the fixing block 6. The mounting bracket 7 is fixedly set on the filling plate 5 and is set on the upper end of the position where the second through groove 8 is opened on the pull rod body 2. Multiple mounting brackets 7 are provided. An extension plate 17 is fixedly set on the upper end of the fixing block 6. Mounting blocks 18 are fixedly set on both ends of the extension plate 17. The extension plate 17 and the mounting bracket 7 cooperate with each other. The extension plate 17 is installed between two mounting brackets 7. Each mounting bracket 7 is provided with a mounting groove 19, which is provided with multiple mounting grooves. The mounting groove 19 and the mounting block 18 cooperate with each other.
[0034] Specifically, when it is necessary to adjust the usable area of the plastic sheet 1, one end of the plastic sheet 1 with the first locking block 10 is pulled so that it passes through the first through slot 3 opened on the drawer body 2. The first locking block 10 then engages with different first fixing holes 4 on the drawer body 2. The engagement of the first locking block 10 with the first retaining ring 9 fixes one end of the plastic sheet 1 to the drawer body 2, thereby changing the length of the plastic sheet 1 retracted into the drawer body 2. This changes the area of the plastic sheet 1 extending out of the drawer body 2, facilitating the adjustment of the usable area of the plastic sheet 1. When installing the filling plate 5, the mating block 16 at one end of the filling plate 5 is engaged with the mating groove 13 on the protruding block 11 at one end of the draw rod body 2, thereby connecting one end of the filling plate 5 with the draw rod body 2. The installation of the filling plate 5 is achieved by the engagement of the second locking block 15 with the second locking ring 14 on the draw rod body 2. When assembling thinner pages, according to the thickness of the pages, the two fixing blocks 6 clamp the pages by the engagement between the mounting block 18 and the different mounting grooves 19 on the mounting frame 7, thereby facilitating the fixing of thinner pages.
[0035] In summary, when using it as a whole:
[0036] When it is necessary to adjust the usable area of the plastic sheet 1, pull one end of the plastic sheet 1 with the first locking block 10 so that it passes through the first through groove 3 opened on the rod body 2. Then, the first locking block 10 cooperates with the different first fixing holes 4 on the rod body 2, and the first locking block 10 cooperates with the first retaining ring 9 to fix one end of the plastic sheet 1 to the rod body 2. This changes the length of the plastic sheet 1 retracted into the rod body 2, thereby changing the area of the plastic sheet 1 extending out of the rod body 2, which facilitates the adjustment of the usable area of the plastic sheet 1.
[0037] When installing the filler plate 5, the mating block 16 at one end of the filler plate 5 is engaged with the mating groove 13 on the protruding block 11 at one end of the rod body 2, thereby connecting one end of the filler plate 5 with the rod body 2. The installation of the filler plate 5 is achieved by engaging the second locking block 15 with the second locking ring 14 on the rod body 2.
[0038] When assembling thinner pages, depending on the thickness of the pages, the two fixing blocks 6 clamp the pages by cooperating with the mounting blocks 18 and the different mounting slots 19 on the mounting frame 7, thereby facilitating the fixing of thinner pages.
