Description
Technical field
The utility model relates to schooling apparatus field, specifically a kind of rubber case.
Background technique
Rubber is a kind of students commonly schooling apparatus, and the rubber of one layer of papery is usually enclosed with outside current rubber
Set, this rubber case need to tear a part, make to use after the bare front end of rubber, exposed part is easily done by dirt
It is dirty, influence the effect of wiping, and exposed part be finished after need to continue another part of tearing, it is particularly troublesome, and people exist
When tearing rubber case, if not paying attention to being easy to tear to pieces rubber case, the beauty of rubber is influenced.
Summary of the invention
The purpose of this utility model is to provide a kind of rubber case.
To achieve the above object, the side walls of the internal side wall of the utility model shell and draw back plate connect, described to push away
The lower part of shell is run through in one end of pulling plate, and the top of the draw back plate is connect by fixed column with rubber patten, the draw back plate
On be provided with multiple elastic limit blocks, the elastic limit block is matched with the limit hole of housing exterior walls, the shell two sidewalls
On be symmetrically arranged with identical clamping device, the clamping device is made of spring and grip block, one end of the spring with
The internal side wall of shell connects, and the side wall of the other end and grip block connects.
Preferably, the upper portion side wall of the grip block is arc setting.
With the above arrangement, the utility model is released rubber by the cooperation of push-and-pull block, limit hole and limiting slot,
If when not used, rubber can be pushed back, and then by the effect of clamping device, prevents rubber from leaking out out of shell, avoid rubber
By filth, the utility model structure is simple, easy to use.
Detailed description of the invention
The utility model is described further now in conjunction with attached drawing.
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, shell, 2, draw back plate, 3, fixed column, 4, rubber patten, 5, elastic limit block, 6, limit hole, 7, clamping
Device, 8, spring, 9, grip block.
Specific embodiment
As shown in Figure 1, the internal side wall of the utility model shell 1 is connect with the side walls of draw back plate 2, the draw back plate
The lower part of shell 1 is run through in 2 one end, and the top of the draw back plate 2 is connect by fixed column 3 with rubber patten 4, the draw back plate
Multiple elastic limit blocks 5 are provided on 2, the elastic limit block is matched with the limit hole 6 of 1 outer wall of shell, 1 liang of the shell
Identical clamping device 7 is symmetrically arranged on side wall, the clamping device 7 is made of spring 8 and grip block 9, the spring 8
One end connect with the internal side wall of shell 1, the other end is connect with the side wall of grip block 9.
The upper portion side wall of the grip block 9 is arc setting.
Working principle: the utility model during installation, first protrudes into erasing rubber from the top of shell 1, pushes rubber, makes
The bottom end of rubber is contacted with clamping device 7, continues to push later, since the upper portion side wall of grip block 9 is arc setting, is reduced
The dynamics of rubber is pushed, later due to the effect of spring 8, grip block 9 can be squeezed by rubber, be connect to rubber and rubber patten 4
The installation of rubber can be completed after touch, when the utility model is used, pushing elastic limit block 5 first, move draw back plate later
2, cooperate another elastic limit block 5 and limit hole 6, rubber can be moved up due to the effect of draw back plate 2, before making rubber
It holds exposed, student is facilitated to use, the utility model reverse operating above-mentioned steps when not used.
