[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0020] The portable shorthand device of this utility model is described below with reference to the accompanying drawings.
[0021] like Figure 1 , Figure 2 As shown, the portable shorthand device provided in this embodiment of the present invention includes a storage box 1 and a shorthand scroll assembly 4. The storage box 1 has a columnar structure, and the shorthand scroll assembly 4 is disposed inside the storage box 1. The shorthand scroll assembly 4 includes a rotating shaft 42, a roll of paper 43, and a spring 44. The rotating shaft 42 is rotatably disposed inside the storage box 1, the roll of paper 43 is wound around the rotating shaft 42, and one end of the roll of paper 43 penetrates through the side wall of the storage box 1. The spring 44 is disposed between the rotating shaft 42 and the storage box 1, and both ends of the spring 44 are connected to the rotating shaft 42 and the inner wall of the storage box 1, respectively.
[0022] Specifically, when using the portable shorthand device of this application, the user only needs to pull out the roll of paper 43 from the side wall of the storage box 1 to write and record on the roll of paper 43. After recording, the roll of paper 43 is released, and the rotating shaft 42 is rotated by the spring 44. The rotating shaft 42 rewinds the roll of paper 43 on its surface, and the roll of paper 43 is automatically stored in the storage box 1. In addition, the storage box 1 has a columnar structure, which is convenient to put in a waist bag or hold in hand, and takes up little space.
[0023] In one embodiment of this utility model, such as Figure 2 , Figure 3 and Figure 5 As shown, a locking component 2 is provided at one end of the rotating shaft 42. The locking component 2 includes a locking rod 22. A pull-out groove 45 is provided at one end of the rotating shaft 42. A multi-faceted guide block 23 is provided at the end of the locking rod 22. The guide block 23 and the pull-out groove 45 are mutually adapted. A locking toothed ring 24 is provided at the bottom of the guide block 23. A positioning groove 11 that is adapted to the locking toothed ring 24 is provided at the bottom of the storage box 1. A pull cap 21 is provided at the bottom of the locking rod 22.
[0024] Specifically, when the roll of paper 43 needs to be pulled out for use, first pull down the pull cap 21. After the locking tooth ring 24 at the bottom of the locking lever 22 disengages from the positioning groove 11, the rotating shaft 42 can rotate freely, and the user can stretch the roll of paper 43 according to the required length. After determining the length, push the pull cap 21 upward, causing the locking tooth ring 24 to re-engage with the positioning groove 11. At this time, the locking lever 22 is locked relative to the storage box 1. Due to the restriction of the multi-faceted guide block 23 at the end of the locking lever 22, the rotating shaft 42 rotates to lock, thereby locking the roll of paper 43 and facilitating writing on the roll of paper 43.
[0025] After the roll of paper 43 has finished writing, pull down the cap 21 again. The locking tooth ring 24 at the bottom of the locking lever 22 leaves the positioning groove 11. The locking lever 22 and the rotating shaft 42 are no longer locked by the storage box 1. At this time, the rotating shaft 42 is driven to rotate by the spring 44. The rotating shaft 42 rewinds the roll of paper 43 and stores it in the storage box 1.
[0026] In one embodiment of this utility model, such as Figure 2 and Figure 4 As shown, a pen 3 is provided at the other end of the rotating shaft 42. The pen 3 is installed inside the rotating shaft 42, and an eraser 31 is provided at the top of the pen 3.
[0027] Specifically, it facilitates the writing use of pen 3, and pen 3 does not occupy the external space of storage box 1. During the writing process, the pen 3 can correct the writing content through the correction tool 31 at its end, which facilitates the repeated use of roll paper 43.
[0028] In one embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the side wall of the storage box 1 is provided with an inlet / outlet slot 12, which is compatible with the roll of paper 43. A pull plate 41 is provided at one end of the roll of paper 43 that passes through the inlet / outlet slot 12, so that the roll of paper 43 can be easily pulled out of the storage box 1 for use.
[0029] To clearly illustrate the above embodiments, refer to Figures 1-6 The working principle of the portable shorthand device of this utility model is as follows: When in use, when it is necessary to pull out the roll of paper 43, first pull down the pull cap 21. After the locking tooth ring 24 at the bottom of the locking rod 22 leaves the positioning groove 11, the rotating shaft 42 can rotate freely. The user can stretch the roll of paper 43 according to the length required by pulling the pull plate 41.
[0030] After determining the length of the roll of paper 43, push the pull cap 21 upwards to drive the locking tooth ring 24 to re-engage with the positioning groove 11. At this time, the locking rod 22 locks relative to the storage box 1. Due to the restriction of the multi-faceted guide block 23 at the end of the locking rod 22, the rotating shaft 42 rotates to lock, thereby locking the roll of paper 43 and making it convenient to use the roll of paper 43 for writing.
[0031] The pen 3 stored in the pivot 42 is convenient for writing, and the pen 3 does not occupy the external space of the storage box 1. During the writing process, the pen 3 can correct the writing content through the correction tool 31 at its end, which makes it convenient for the roll of paper 43 to be used repeatedly.
[0032] After the roll of paper 43 has finished writing, pull down the cap 21 again. The locking tooth ring 24 at the bottom of the locking lever 22 leaves the positioning groove 11. The locking lever 22 and the rotating shaft 42 are no longer locked by the storage box 1. At this time, the rotating shaft 42 is driven to rotate by the spring 44. The rotating shaft 42 rewinds the roll of paper 43 and stores it in the storage box 1.
[0033] In summary, the portable shorthand device of this utility model embodiment, by setting a roll of paper in a cylindrical storage box, allows for shorthand taking by simply pulling out the roll of paper when in use. The roll of paper does not occupy separate space, and it is automatically stored in the storage box by a spring. Moreover, the cylindrical storage box is convenient to carry in a waist bag or in hand, and occupies little space.
[0034] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
