Description
Technical field
The utility model relates to students' supplies field, particularly relates to a kind of erasing rubber.
Background technology
In routine work life, rubber is a kind of study article of student's indispensability, and in daily learning process, if desired the scope of wiping is less, and there is word in the place adjacent with wiping position, then be not easy the place that a wiping accurately needs to wipe, in order to make the contact surface of erasing rubber and paper reduce, what need the cross section of rubber to do is less, therefore, it is comparatively thin that rubber will become, and uses like this and will often therefore too carefully fracture, waste rubber also cumbersome; In addition, present rubber, usually only as the study article wiping wrong written trace, does not have other function substantially, if can study a kind of easy wiping written trace and have the erasing rubber of other functions multiple more among a small circle, has important practical significance.
Utility model content
The purpose of this utility model is to provide a kind of erasing rubber.
The technical solution of the utility model is: a kind of erasing rubber, comprise the oversheath of rubber and hollow, rubber is arranged in oversheath, be used in conjunction with each other with oversheath, it is characterized in that: described oversheath one end is closed, the other end is provided with upper shield, described upper shield is fixedly connected with by hinge with oversheath one side, described oversheath is provided with slide switch, for fixing upper shield, upper shield and oversheath are closed, described oversheath inwall is provided with the fin with oversheath axis parallel, described oversheath outer wall is provided with and refers to trace groove, described oversheath closing end is provided with recording device, timer and warning device, described timer is connected with warning device electricity, described rubber surface is provided with the groove corresponding with fin, rubber and oversheath are agreed with mutually.
Further, described oversheath outer wall scribbles fluoresent coating.
Further, described warning device is buzzer siren.
Further, described finger trace groove is 2, is symmetrically distributed on oversheath outer wall.
The beneficial effects of the utility model are:
A kind of erasing rubber, the existence of oversheath can make rubber be convenient to wiping wrong vestige among a small circle, and fluoresent coating is convenient to find after rubber is lost, recording device can record lecture contents, timer and alarm energy timed reminding student complete learning tasks, and this erasing rubber structure is simple, easy to use.

Detailed description of the invention
Below in conjunction with accompanying drawing, brief description is made to detailed description of the invention of the present utility model.
As Fig. 1, a kind of erasing rubber shown in 2, comprise the oversheath 2 of rubber 1 and hollow, described oversheath 2 outer wall scribbles fluoresent coating, rubber 1 is arranged in oversheath 2, be used in conjunction with each other with oversheath 2, described oversheath 2 one end is closed, the other end is provided with upper shield 3, described upper shield 3 is fixedly connected with by hinge with oversheath 2 one side, described oversheath 2 is provided with slide switch 4, for fixing upper shield 3, upper shield 3 is closed with oversheath 2, described oversheath 2 inwall is provided with the fin 5 with oversheath 2 axis parallel, described oversheath 2 outer wall is provided with and refers to trace groove 6, described finger trace groove 6 is 2, be symmetrically distributed on oversheath 2 outer wall, described oversheath 2 closing end is provided with recording device 7, timer 8 and warning device 9, described warning device 9 is buzzer siren, described timer 8 is connected with warning device 9 electricity, described rubber 1 surface is provided with the groove 10 corresponding with fin 5, rubber 1 and oversheath 2 are agreed with mutually.
Working method: the groove on rubber is put in oversheath along the fin on oversheath, during use, press...with one's finger on finger trace groove, a little firmly rubber can be fixed, then wiping mistake vestige, oversheath is provided with fluoresent coating, student can be facilitated to find rubber in the dark, recording device can by teacher at school time the content record said get off, review after class, timer and warning device can facilitate student's timing, then remind student by warning device afterwards.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
