Description
Technical field
The present invention relates to realia field more particularly to a kind of chalk sleeves.
Background technology
Chalk is the essential educational aid of teacher.The main component of chalk is gypsum, meets sweat solution, generates basic species
Matter is very big to skin damage.Chalk, which is used for a long time, can cause skin to become dry, coarse, breach, itching；Especially in cold
The north, teachers will wash away after class chalk on hand bits, one day several class, daily will with icy water contact it is more
Secondary, hand is also easy to become to chap.
In view of the above problems, chalk sleeve comes into being, however, the chalk sleeve on existing market, to the fixation of chalk compared with
Pine, chalk are easily marked from chalk sleeve, and existing chalk sleeve is relatively low to the utilization rate of chalk, has a big chunk chalk to bury
It cannot be used in chalk sleeve, be badly in need of solving as a result,.
Invention content
It is an object of the invention in view of the above-mentioned problems, a kind of chalk sleeve is provided, to solve existing chalk sleeve fixation chalk
It is not firm, the not high problem of chalk utilization rate.
The purpose of the present invention is be achieved through the following technical solutions：
A kind of chalk sleeve, including chalk sleeve ontology, the chalk sleeve ontology include sequentially connected first retaining ring, first
Adjusting set, fixing sleeve, the second adjusting set, the second retaining ring, the fixing sleeve include rigid housing and for fixing chalk
One elastic clamping inner sleeve, the second elastic clamping inner sleeve, the first elastic clamping inner sleeve are set to one end of rigid jacket internal,
The rigidity jacket internal is arranged close to the first limiting plate is provided at the first elastic clamping inner sleeve in second elastic clamping
It is placed in the other end of rigid jacket internal, the rigidity jacket internal is close to being provided with the second limit at the second elastic clamping inner sleeve
Plate, first adjusting set, the second adjusting sleeve structure are identical, and specifically include magnetic body, the magnetism body and fixing sleeve
Magnetism connection, and sleeve joint hole is provided on magnetic body, the aperture of the sleeve joint hole is more than the outer diameter of chalk, first locking
Ring, the second locking ring structure are identical, and specifically include snap ring, and the snap ring is provided with opening.
As a preferred embodiment of the present invention, the inner wall of the first elastic clamping inner sleeve and the second elastic clamping inner sleeve
Inner wall on be both provided with protrusion for increasing frictional force.
As a preferred embodiment of the present invention, the bullet for increasing frictional force is provided on the inner wall of the snap ring
Property protrusion.
As a preferred embodiment of the present invention, the magnetism body includes multiple magnetic sections being arranged in a linear, adjacent
Magnetic connection between magnetic sections.
Beneficial effects of the present invention are, a kind of chalk sleeve has the advantages of simple structure and easy realization, and both ends can install powder
Pen, and then different colours chalk can be installed, it is used convenient for teacher, and the chalk sleeve fixes the rear end of chalk by fixing sleeve,
The front end that chalk is fixed by the retaining ring of the first retaining ring/second, has the effect of fixed so that chalk will not slip,
In addition, by adding the adjusting set of the first adjusting set/second, and then in use for some time, the first adjusting set/second can be adjusted
Section set is removed so that internal chalk exposes, and substantially increases the utilization rate of chalk.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of chalk sleeve of the present invention.
Specific implementation mode
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.It is appreciated that
It is that embodiment described herein is used only for explaining the present invention rather than limitation of the invention.
It please refers to shown in Fig. 1, Fig. 1 is a kind of structural schematic diagram of chalk sleeve of the present invention.
In this present embodiment, a kind of chalk sleeve, including chalk sleeve ontology, the chalk sleeve ontology include sequentially connected
One retaining ring 1, the first adjusting set 2, fixing sleeve 3, the second adjusting set 4, the second retaining ring 5, the fixing sleeve 3 include rigid housing
And the first elastic clamping inner sleeve 6, the second elastic clamping inner sleeve 7 for fixing chalk, the first elastic clamping inner sleeve 6 are arranged
In one end of rigid jacket internal, the rigidity jacket internal is close to being provided with the first limiting plate at the first elastic clamping inner sleeve 6
8, the second elastic clamping inner sleeve 7 is set to the other end of rigid jacket internal, and the rigidity jacket internal is close to the second bullet
It is provided with the second limiting plate 9, the inner wall and the second elastic clamping inner sleeve 7 of the first elastic clamping inner sleeve 6 at property inner clamping sleeve 7
Inner wall on be both provided with protrusion (not being painted in figure) for increasing frictional force, first adjusting set 2, the second adjusting set 4
Structure is identical, and specifically includes magnetic body, and the magnetism body is connect with 3 magnetism of fixing sleeve, and is provided with set on magnetic body
Hole is connect, the aperture of the sleeve joint hole is more than the outer diameter of chalk, and first retaining ring 1,5 structure of the second retaining ring are identical, and have
Body includes snap ring, and the snap ring is provided with opening, and is provided on the inner wall of snap ring for increasing frictional force
Elastic bumps (not being painted in figure).
Preferably, the magnetic body includes multiple magnetic sections being arranged in a linear, magnetic connection between adjacent magnetic section；
By using above structure so that as soon as after chalk has used section, a magnetic sections can be removed, you can so that chalk is exposed, structure
Simply, it is easily achieved.
A kind of above-mentioned chalk sleeve, which has, to be had the advantages of simple structure and easy realization, and fixed feature, both ends can install powder
Pen, and then different colours chalk can be installed, it is used convenient for teacher, and the chalk sleeve fixes the rear end of chalk by fixing sleeve 3,
The front end that chalk is fixed by 1/ second retaining ring 5 of the first retaining ring, has the effect of fixed so that chalk will not be slided
It is de-, in addition, by adding 2/ second adjusting set 4 of the first adjusting set, and then in use for some time, it can be by the first adjusting set 2/
Second adjusting set 4 is removed so that internal chalk exposes, and substantially increases the utilization rate of chalk.
Above example is to elaborate that the basic principle and characteristic of the present invention, the present invention are not limited by above-described embodiment,
Without departing from the spirit and scope of the present invention, the present invention also has various changes, these changes and modifications are all fallen
Enter in scope of the claimed invention.The claimed scope of the invention is defined by the following claims.
