The profile of tooth structure does the bottom outward flange is equipped with the profile of tooth sand grip, shells inner wall is last be equipped with with profile of tooth sand grip matched with profile of tooth recess, the profile of tooth sand grip inserts in the profile of tooth recess. Profile of tooth sand grip cross -section is right angled triangle. Profile of tooth sand grip base is in the coplanar with the bottom lower surface, profile of tooth sand grip hypotenuse is 35~65 degrees with the lower surface corner dimension. Casing bottom to top evenly sets up the profile of tooth recess. Profile of tooth recess in the casing sets up in casing internal surface opposite side.
Description
Technical field
The present invention relates to stationery field, and in particular to a kind of improved rubber case.
Background technology
Rubber is one of study article commonly used in student main forces, and the work performed meritorious deeds never to be obliterated is played to student learning
With.Generally new rubber buys its outer rubber case for being surrounded by papery, is packaged with transparent plastic, transparent plastic when using outside rubber case again
Remove, some people are directly then will to tear off together with the whole outer package of rubber case, but many wrapping papers one cannot be saved and torn,
The naked leakage of the monoblock of rubber one is caused once whole destruction is torn outside, it is easy to by filth, wipe unclean when using, reduce making
Use effect；Simultaneously as rubber is more soft and easily dirty, this causes rubber not also to be finished just usually has become dirty
And there is fracture or pit, not only affect the attractive in appearance of rubber, and it is very unhygienic that rubber is used；Rubber during use
Skin volume being worn slowly diminishes, and is increasingly difficult to be pinched, and affects Students ' Learning.Patent name is《A kind of rubber case》's
Patent effectively solves the problems referred to above, but still suffers from problems with：First, will not fracture to ensure rubber, cause housing harder,
Handss pinch the more uncomfortable problem of shell when using, two, due between rubber and bottom without effectively connection, once rubber external diameter is omited
During less than housing, the problem that rubber easily comes off from rubber case.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of improved rubber case, and easy to use, effect is good, and can
Keep rubber cleaning.
The present invention is achieved through the following technical solutions：
A kind of improved rubber case, including housing, also including the bottom being movably set in housing, the bottom outward flange
Profile of tooth raised line is provided with, the inner walls are provided with the profile of tooth groove being engaged with profile of tooth raised line, the profile of tooth raised line insertion tooth
In connected in star, the bottom upper surface is provided with fixed seat, and the housing outer rim is provided with rubber blanket, sets on the rubber blanket outer surface
There are the bar shaped anti-slip veins of projection, the rectangular triangle in the profile of tooth raised line section, the profile of tooth raised line base and bottom lower surface
In same plane, the profile of tooth raised line hypotenuse is 35 ~ 65 degree with lower surface corner dimension, and the housing bottom is uniform to top
Profile of tooth groove is set, and the profile of tooth groove in the housing is arranged at shell inner surface opposite side.
Further improvement of the present invention scheme is that the fixed seat is to be arranged at the Shaftless spiral blade in the middle part of bottom.
Further improvement of the present invention scheme is, a diameter of 2 ~ 10mm of the Shaftless spiral blade, and top is apart from bottom
2 ~ 5mm of upper surface.
Further improvement of the present invention scheme is that the rubber blanket is pasted on housing outer surface.
It is an advantage of the current invention that：
First, the present invention arranges the tooth-shape structure for cooperating on housing and base so that base in the housing can only be past
One direction motion so that the rubber for exposing needs to expose rubber toward a direction pushing and pressing base after using abrasion, only
Housing.
2nd, there is the problems such as rupturing in the use of inventive shell so that rubber is no longer easily dirty.
3rd, the present invention is provided with tooth-shape structure from bottom in housing opposite side to top so that base can be from housing
Bottom is filled in, top ejects, and is easy to install rubber again.
4th, the present invention arranges limitting casing and fixed seat on base can make rubber fixation more stable.
5th, the present invention is provided with Shaftless spiral blade in bottom upper surface, when rubber is installed, can screw in helical blade
Rubber is fixed inside rubber, is come off from housing when preventing rubber external diameter less than housing.
6th, the Shaftless spiral blade that the present invention is used is less, and rubber will not be caused compared with havoc, but to the fixation of rubber
More consolidate.
7th, the present invention has pasted rubber blanket in housing outer surface, and the sensation for being affectedly bashful rubber case is more comfortable, on rubber blanket
It is provided with skid resistance strip so that when in use without the need for energetically pinching housing.
Description of the drawings
Fig. 1 is shell structure schematic diagram.
Fig. 2 is bottom cover structure schematic.
Fig. 3 is the cross-sectional view after housing coordinates with bottom.
Specific embodiment
A kind of improved rubber case as shown in Fig. 1 ~ 3, including housing 1, also including the bottom being movably set in housing 1
2, the outward flange of the bottom 2 is provided with profile of tooth raised line, and the inwall of the housing 1 is provided with the profile of tooth groove being engaged with profile of tooth raised line,
In the profile of tooth raised line insertion tooth connected in star, the upper surface of the bottom 2 is provided with fixed seat 3, and the outer rim of the housing 1 is provided with rubber blanket
4, the outer surface of the rubber blanket 4 is provided with the bar shaped anti-slip veins of projection.The fixed seat 3 is shaftless in the middle part of bottom 2 to be arranged at
Helical blade.A diameter of 2 ~ 10mm of the Shaftless spiral blade, top is apart from bottom 2 ~ 5mm of upper surface.The profile of tooth raised line
The rectangular triangle in section.The profile of tooth raised line base and the lower surface of bottom 2 are in same plane, the profile of tooth raised line hypotenuse with
Lower surface corner dimension is 55 degree.The bottom of the housing 1 to top is uniformly arranged profile of tooth groove.Profile of tooth in the housing 1 is recessed
Groove is arranged at shell inner surface opposite side.The rubber blanket 4 is pasted on the outer surface of housing 1.
Still as shown in Fig. 1 ~ 3, rubber is installed on bottom 2, rubber is filled in together with bottom 2 from the bottom of housing 1, bottom
After profile of tooth groove on 2 outer peripheral profile of tooth raised lines and the inwall of housing 1 cooperates so that bottom 2 can only be under force
Toward the top movements of housing 1（Raised line lower surface is mutually supported with groove upper surface after raised line and groove fit so that raised line cannot move to
Bottom groove）, it is ensured that rubber gradually can expose from the top of housing 1 during use, can be by bottom 2 after rubber is finished
Support out from the top of housing 1, recycle again, using so that more comfortable when being affectedly bashful housing 1 for rubber blanket 4 is entered using rubber
Without using energetically housing can be pinched when row is wiped.
