Abstract
The invention belongs to the field of study articles and particularly relates to an eraser protective case. The eraser protective case is characterized by comprising a protective outer shell, an eraser seat and a spiral push rod, wherein the protective outer shell is a lidless barrel; a threaded hole is formed in the bottom end of the protective outer shell; a screw thread is designed in the spiral push rod and is in threaded fit with the threaded hole of the protective outer shell; the spiral push rod penetrates through the threaded hole to extend into the protective outer shell; the outer diameter of the eraser seat is smaller than the inner diameter of the protective outer shell and the eraser seat can slide in the protective case and is provided with an eraser; the total length of the eraser seat and the spiral push rod is smaller than the length of the protective outer shell. The eraser protective case has the beneficial effects that the structure is simple; the eraser can be retracted into the protective case so as to be protected and prevented from being contaminated by contaminants; meanwhile, the spiral push rod is adjusted to expose the eraser when the eraser is gradually rubbed and shortened during usage, and the phenomenon that the eraser is not easy to hold is avoided; the eraser can be replaced after being mostly used, and the purpose of recycling is achieved.
Description
Technical field
The invention belongs to study article field, particularly a kind of rubber containment vessel.
Background technology
Rubber is one of study article often used in student main forces, plays a part to perform meritorious deeds never to be obliterated to the study of student.But existing rubber be substantially all the naked leakage of a monoblock outside, be easy to by filth, wipe clean during use, reduce result of use; Meanwhile, in use procedure, rubber volume being worn slowly diminishes, and is more and more not easily pinched, affects Students ' Learning.
Summary of the invention
The present invention, in order to solve above asking a question, makes up the deficiency of conventional art, provides a kind of structure simple, rubber containment vessel easy to use.
The present invention is achieved through the following technical solutions:
A kind of rubber containment vessel, it is characterized in that: comprise protecting sheathing, rubber seat and spiral handspike, protecting sheathing is the drum of uncovered, there is screwed hole protecting sheathing bottom, spiral handspike is provided with screw thread and matches with the screwed hole screw thread of protecting sheathing, and spiral handspike stretches in protecting sheathing through screwed hole; Rubber seat external diameter is less than protecting sheathing internal diameter, can slide in containment vessel, and rubber seat is provided with rubber; The total length of rubber seat and spiral handspike is less than the length of protecting sheathing.
The invention has the beneficial effects as follows, structure is simple, and rubber is recoverable in containment vessel, plays the effect of protection rubber, avoids rubber by filth; Meanwhile, containment vessel has certain length, and along with rubber length being worn slowly diminishes in use procedure, adjustable screw push rod rubber can spill, and there will not be the phenomenon that rubber is not easily pinched; The rubber of finishing using can be changed, and realizes the object recycled.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is internal structure schematic diagram of the present invention.
In figure, 1 rubber, 2 protecting sheathings, 3 rubber seats, 4 spiral handspikes.
Detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.
Rubber containment vessel of the present invention, it is characterized in that: comprise protecting sheathing 2, rubber seat 3 and spiral handspike 4, protecting sheathing 2 is the drum of uncovered, there is screwed hole protecting sheathing 2 bottom, spiral handspike 4 is provided with screw thread and matches with the screwed hole screw thread of protecting sheathing 2, and spiral handspike 4 stretches in protecting sheathing 2 through screwed hole; Rubber seat 3 external diameter is less than protecting sheathing 2 internal diameter, can in containment vessel 2 slide, rubber seat 3 is provided with rubber 1; Rubber seat 3 is less than the length of protecting sheathing 2 with the total length of spiral handspike 4.
Diminish along with the use slowly of rubber length is worn in use procedure, adjustment is stretched into spiral handspike 4 rubber and can be spilt, and does not affect rubber use and can protect rubber again.
