Description
Technical field
The utility model relates to stationery technical fields, and in particular to a kind of scalable erasing rubber.
Background technique
Common erasing rubber is that cuboid is blocky, and when wiping wrong word, erasing rubber and paper-contacting surface product are larger, can be missed
Other writings are wiped, while the volume of erasing rubber is larger, can block sight, causes when in use, can accidentally wipe other writings.Such as
Directly elongate in shape is made in erasing rubber by fruit, since the material is soft for erasing rubber, is easily snapped off, be unfavorable for instead using.
Utility model content
The purpose of this utility model is to provide a kind of scalable erasing rubbers, can be missed with solving existing erasing rubber when in use
The problem of wiping other writings.
The technical solution that the utility model solves above-mentioned technical problem is as follows:
A kind of scalable erasing rubber, comprising: snap connection in the shell of elongated rod-shaped, rubber brush assembly and with shell
Revolving part；Shell includes outer cover body and the slide opening through outer cover body both ends, and rubber brush assembly is placed in slide opening；Erasing rubber
Component includes erasing rubber ontology and the sliding part that connect with erasing rubber ontology, and sliding part and slide opening cooperate, sliding part be equipped with
The identical threaded hole of slide opening extending direction；Revolving part includes rotating part and the hand-held part that connect with rotating part, and rotating part passes through
Screw thread is connect with threaded hole, and hand-held part is placed in outside outer cover body.
The sliding part and slide opening of the utility model cooperate, and make sliding part that can only do the reciprocating motion of straight line in slide opening
It is unable to make rotating motion, erasing rubber ontology moves in slide opening with sliding part；Revolving part is existed by buckle and cage connection
Together, make revolving part that can only make rotating motion and cannot move in a straight line relative to shell.The rotating part and threaded hole of revolving part
It is connected with each other by screw thread, when revolving part rotates, drives sliding part to move in a straight line by screw thread, thus by erasing rubber
Ontology is pushed to outside slide opening or takes in slide opening, and the adjustable length for being placed in the outer erasing rubber ontology of slide opening.It is using
When, scalable erasing rubber carries out erasing operation with the posture that holds a pen, and it is easy to use and be conveniently adjusted using angle, facilitate observation
The writing of erasing prevents from accidentally wiping；The contact area of erasing rubber ontology and paper is small, can prevent other writings from accidentally being wiped, simultaneously
Easy fracture is not allowed under the supporting role of shell；In addition, the length that erasing rubber ontology is placed in outside slide opening can be transferred arbitrarily, not
In use, erasing rubber ontology can be accommodated in slide opening, prevent from being contaminated.
Further, the side wall of above-mentioned slide opening is equipped with the sliding slot in the same direction with slide opening, and the outside of sliding part is equipped with and sliding slot phase
Matched sliding block.
The sliding slot and sliding block of the utility model cooperate, and limit slippage part makes rotating motion, and sliding block is made to drive sliding part
It is intelligently moved in a straight line in the sliding slot of slide opening.
Further, one end of above-mentioned slide opening is equipped with the first protrusion, and rotating part is equipped with the second protrusion, the first protrusion and second
The groove that protrusion and hand-held part are formed matches.
First protrusion and the second protrusion of the utility model cooperate, i.e. the first protrusion is placed in the second protrusion and hand-held part
In the groove of formation, snap connection formation between shell and sliding part；First protrusion is limited by the second protrusion and hand-held part
The freedom degree of rectilinear direction makes that opposite rotary motion can only be done between revolving part and shell.First protrusion is arranged second
Between protrusion and hand-held part, self-locking, simplified assembling process can be realized in assembling.
Further, the outside of the erasing rubber outlet end of above-mentioned outer cover body is equipped with the conical surface.
The conical surface of the outer cover body setting of the utility model can reduce the blocking to sight, facilitate observation.
Further, above-mentioned erasing rubber ontology is in elongated rod-shaped.
The elongated rod-shaped erasing rubber ontology of the utility model and the contact area of paper are smaller, can be effectively prevented and accidentally wipe it
Its writing, due to the adjustable length being placed in outside slide opening and under the supporting role of outer cover body, it is not easy to be broken.
Further, above-mentioned scalable erasing rubber further includes the hairbrush connecting with the hand-held part.
The hairbrush of the utility model can clear up the eraser chips left after due to erasing rubber ontology.
The utility model has the following beneficial effects:
The position of the adjustable erasing rubber ontology of the utility model, will not block the sight of user when in use, be conducive to
User's observation；In addition, the utility model is integrally in elongated rod-shaped, and is also set as elongated rod-shaped for erasing rubber ontology, in thin
The erasing rubber ontology of elongated rod shape and the contact area of paper are smaller, prevent other writings from accidentally being wiped.
