Description

A portable notebook

technical field

The present invention relates to a portable note-taking tool, which is a divisional application with the application number 2014106853012 filed on 2014-11-25 and named as a portable note-taking tool.

Background technique

In daily life and work, people often need to temporarily record some information memos. At this time, paper and pen are needed at the same time. The amount of information is different, and the required paper size is also different, otherwise it will cause waste. In order to solve the above problems, such as the patent 201020617113 pen with note paper, including pen cap, pen case, pen core and other parts, the inside of the pen case is equipped with a winding device composed of a rotating shaft sleeve and a torsion spring, and the note paper is wound on the rotating shaft sleeve On the top, there is a paper output slot on the surface of the pen shell. When in use, people can pull out the note paper from the paper output slot and tear it off. The note paper that is pulled out too long can be rolled back under the action of the spring. There is an elastic card on the shaft sleeve. head, you can lock the shaft sleeve to prevent automatic curling of note paper. For example, patent 201220208978.3 is a sticky note pen, including a refill and sticky note paper. The spirally rolled post-it note can be used as the pen holder of the pen. The back of the post-it note is sticky. When you need to record information, you only need to tear off a section and hold the pen holder to write. The pen and sticky note are combined for easy portability. However, when these products are actually used, there are disadvantages such as not beautiful appearance, not convenient enough to take the paper, and few roll papers that can be placed.

Contents of the invention

The technical problem to be solved by the present invention is to provide a portable note-taking tool with compact structure, convenient roll paper access and large volume of roll paper.

The technical solution adopted by the present invention to solve the above-mentioned problems is: a portable note-taking tool, comprising a shell with a head cover and a tail cover, an inner tube fitted in the inner cavity of the outer shell, and an inner tube installed in the inner cavity of the inner tube for installing roll paper. The central shaft, the saw blade installed on the outer wall of the inner tube and used to cut the roll paper, and the pen used to drive the central shaft to rotate, and an anti-reverse device to prevent the roll paper from being reversed is provided between the inner tube and the central shaft , the inner tube is provided with an inner tube through groove along the length direction for the roll paper to pass through, the saw tooth edge of the saw blade is placed at the inner tube through groove, and the outer shell and the inner tube A housing through slot for roll paper to pass through is opened at the position corresponding to the through slot; the pen is placed in the hollow inner cavity of the central axis, and the tail of the pen protrudes from the tail cap ; The outer peripheral surface of the inner tube is provided with a first inclined plane and a second inclined plane respectively, and the first inclined plane and the second inclined plane are placed on both sides of the inner pipe through groove respectively, and the saw blade It is fixedly installed on the first slope, and the back of the saw blade is provided with a plurality of pressing blocks, and the pressing blocks all abut against the second slope.

Compared with the prior art, the present invention has the advantages that: the portable note-taking utensil has a compact structure, is designed in a tubular shape, and the rolled paper is installed on the central shaft. When in use, the roll paper is cut off by the serrated edge of the saw blade at the through groove of the shell, and different lengths can be taken at will according to one's own needs, and an anti-reversal device is installed between the inner tube and the central shaft to prevent the roll paper from being retracted. Inside the inner tube for easy access next time. And the pen is set in the hollow inner cavity of the central axis, which is very convenient to take, easy to carry, and brings great convenience to the user; the outer peripheral surface of the inner tube is respectively provided with a first slope and a second slope, the first The inclined plane and the second inclined plane are respectively placed on both sides of the inner pipe channel, the saw blade is fixedly installed on the first inclined plane, and a plurality of pressing blocks are arranged on the back of the saw blade, and the pressing blocks all abut against the second inclined plane superior. In this way, the installation of the saw blade is more reasonable, and the pressing block on the saw blade can play the role of pressing the roll paper, further preventing the roll paper from being retracted into the inner tube, and making it convenient to take it next time.

The inner cavity of the central shaft is provided with an elastic expansion sleeve matched with the nib of the pen, the outer wall of the elastic expansion sleeve is tightly fitted with the central shaft, and the inner wall of the elastic expansion sleeve is Conical, and the wall body at the lower part of the elastic expansion sleeve is evenly provided with a plurality of expansion sleeve through grooves along the circumferential direction. In this way, since the inner wall of the elastic expansion sleeve is tapered, after the pen is inserted into the elastic expansion sleeve, the bonding force between the elastic expansion sleeve and the central shaft is better. As long as the pen is rotated, the central shaft can be driven by the elastic expansion sleeve to rotate. Thereby the roll paper is further driven to rotate, so that the roll paper passes through the inner tube through groove and the outer shell through groove. The through groove of the expansion sleeve can further increase the elasticity of the elastic expansion sleeve and increase the tension with the pen and the central shaft.

The anti-reversing device consists of a ratchet mounted on the upper part of the central shaft, a shrapnel set in the groove on the inner wall of the inner tube and cooperating with the ratchet, and a stopper set on one side of the shrapnel. There is a gap between the limiting column and the ratchet, and central axis positioning ribs matching with the positioning grooves of the ratchet are provided on the outer peripheral surfaces of both ends of the central shaft. When taking the roll paper, the ratchet rotates together with the central shaft. Since there is a gap between the ratchet and the limit post, there will be no interference, and the ratchet can directly squeeze the shrapnel to rotate; if the central shaft rotates in the reverse direction, the limit post will It will withstand the shrapnel, and the ratchet will be blocked and unable to rotate, which can effectively prevent the central axis from inverting, and the roll paper will not be easily retracted into the inner tube, avoiding inconvenience for the next use.

The inner wall of the shell is provided with shell positioning ribs along the circumference, and the outer wall of the inner tube is correspondingly provided with inner tube positioning grooves matching the shell positioning ribs. In this way, when assembling, the positioning groove of the inner tube is matched with the positioning rib of the outer shell, so that the inner tube and the outer shell can be quickly positioned, which is more convenient; at the same time, spare shells of different styles and patterns can be easily replaced, making the portable note-taking utensils more beautiful and full of energy. personality.

The head cap is screwed to the upper part of the inner tube, and the tail cap is screwed to the lower part of the inner tube. In this way, the assembly of the portable note-taking utensil is more convenient.

The lower part of the central shaft is provided with a central shaft boss for limiting the position of the roll paper. The roll paper can be limited to facilitate the alignment of the roll paper with the inner tube slot and the outer shell slot.

It also includes a buckle assembly, and the top of the head cover is provided with a hanging hole for hanging the buckle assembly. The note holder can be conveniently hung on a backpack or used as a key chain through the hanging buckle component, which is more convenient to carry.
