Abstract
The invention belongs to study article fields; in particular to a kind of rubber protective shell that can be recycled; it is characterized by comprising protection shell, rubber seat and spiral handspikes; protecting shell is the drum of uncovered; there is threaded hole in protection shell bottom end; spiral handspike is equipped with screw thread and matches with the threaded hole screw thread of protection shell, and spiral handspike passes through threaded hole and protrudes into protection shell；Rubber seat outer diameter is less than protection internal diameter of outer cover, can slide in protective shell, be equipped with rubber on rubber seat；The total length of rubber seat and spiral handspike is less than the length of protection shell.The invention has the advantages that structure is simple, rubber is recoverable in protective shell, playing the role of protection rubber, avoids rubber by filth；Meanwhile as rubber length being worn slowly becomes smaller in use process, it is not in that rubber is not easy the phenomenon that being pinched that adjusting spiral handspike rubber, which can leak out,；It can be replaced using the rubber finished, realize the purpose of recycling.
Description
Technical field
The invention belongs to study article field, in particular to a kind of rubber protective shell that can be recycled.
Background technique
Rubber is one of the study article being commonly used in student main forces, plays the work performed meritorious deeds never to be obliterated to the study of student
With.But existing rubber is substantially the naked leakage of a monolith outside, it is easy to which by filth, when use is rubbed uncleanly, and is reduced
Using effect；Meanwhile rubber volume being worn slowly becomes smaller in use process, is increasingly not easy to be pinched, and influences student
It practises.
Summary of the invention
The present invention is mentioned above in order to solve the problems, such as, makes up the deficiency of traditional technology, and it is simple to provide a kind of structure, uses
Convenient rubber protective shell.
The present invention is achieved through the following technical solutions:
A kind of rubber protective shell that can be recycled, it is characterised in that: including protecting shell, rubber seat and spiral handspike,
Protecting shell is the drum of uncovered, and there is threaded hole in protection shell bottom end, and spiral handspike is equipped with screw thread and the spiral shell with protection shell
Pit screw thread matches, and spiral handspike passes through threaded hole and protrudes into protection shell；Rubber seat outer diameter is less than protection internal diameter of outer cover, can
It is slided in protective shell, rubber is installed on rubber seat；The total length of rubber seat and spiral handspike is less than the length of protection shell.
The invention has the advantages that structure is simple, rubber is recoverable in the work in protective shell, playing protection rubber
With avoiding rubber by filth；Meanwhile protective shell has certain length, the quilt in use process with rubber length slowly
Abrasion becomes smaller, and it is not in that rubber is not easy the phenomenon that being pinched that adjusting spiral handspike rubber, which can leak out,；Use the rubber finished
It can replace, realize the purpose of recycling.
Detailed description of the invention
The present invention will be further described below with reference to the drawings.
Fig. 1 is schematic diagram of internal structure of the invention.
In figure, 1 rubber, 2 protection shells, 3 rubber seats, 4 spiral handspikes.
Specific embodiment
Attached drawing is a kind of specific embodiment of the invention.
Rubber protective shell of the invention, it is characterised in that: including protection shell 2, rubber seat 3 and spiral handspike 4, protection is outer
Shell 2 is the drum of uncovered, and there is threaded hole in protection 2 bottom end of shell, and spiral handspike 4 is equipped with screw thread and the screw thread with protection shell 2
Hole screw thread matches, and spiral handspike 4 passes through threaded hole and protrudes into protection shell 2；3 outer diameter of rubber seat is less than protection 2 internal diameter of shell,
Can 2 sliding in protective shell, rubber 1 is installed on rubber seat 3；The total length of rubber seat 3 and spiral handspike 4 is less than protection shell
2 length.
Become smaller in use process as the use of rubber length slowly is worn, 4 rubber of spiral handspike is protruded into adjusting
It leaks out, does not influence rubber and use and can protect rubber.
