1, consumable quantity is little, and product cost is lower, for ease of maintenaince and change.
2, for embodying characteristics of energy saving, this product makes every effort to make full use of chalk.
3, material lightweight, easy to use.
Summary of the invention
The present invention will provide a kind of propelling chalk sleeve, and this chalk sleeve structure is simple, and material price is cheap, effectively can utilize chalk, economize on resources, and simple to operate, easy to use.
For achieving the above object, technical scheme of the present invention is: a kind of propelling chalk sleeve, comprise pullover, cover body, interior stud, cap bag, be characterized in: interior stud is placed in cover body endoporus, be threaded with between cover body, pullover and cap bag is placed in the two ends of cover body outside cylinder respectively, with between cover body outside cylinder respectively by tongue and groove axis of no-feathering to being fixedly connected with, radial for being rotatably connected, pullover head is provided with regular polygon through hole, interior stud is provided with axial regular polygon blind hole, and the regular polygon blind hole on interior stud corresponds to the regular polygon through hole of pullover head.
Be installed with regular polygon chalk in regular polygon blind hole on the regular polygon through hole of pullover head and interior stud, and the regular polygon through hole of pullover head is connected with matched in clearance between regular polygon chalk.
Cover body is broken cover body by two and half and is combined.Regular polygon through hole and regular polygon blind hole are square or regular pentagon or regular hexagon through hole and blind hole.Pulloverly to be made up of soft material.
The invention has the beneficial effects as follows:
Chalk sleeve of the present invention is primarily of the female cover body of band, pullover, cap bag and with externally threaded interior stud composition, and cover body is made up of the two halves that can radially freely split.By pullover with cover the relatively rotating of body, drive the rotation of hexagonal chalk, and then drive inner stud to relatively rotate with cover body, realize moving axially of chalk by threaded function, chalk can spinning in and out.The present invention is reasonable in design, structure is simple, with low cost, and it is easy to use, point the finger dry decortication problem be infected with chalk dust and caused when can solve class-teaching of teacher, pullover employing low durometer stock, avoids the fracture of chalk, the problem that chalk effectively utilizes can also be solved simultaneously, have highly application value.
Structure of the present invention is simple, and material price is cheap, cost-saving.Effectively can utilize chalk, economize on resources.And simple to operate, easy to use, greatly can promote, effectively agree with teacher's demand.Market prospects are very considerable.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figure 1, propelling chalk sleeve of the present invention, comprises pullover 1, cover body 2, interior stud 4, cap bag 5, chalk 3.
Interior stud 4 is placed in cover body 2 endoporus, be threaded between interior stud 4 with cover body 2, pullover 1 and cap bag 5 be placed in the two ends of cover body 2 outside cylinder respectively, and pullover 1 and between cap bag 5 with cover body 2 outside cylinder respectively by tongue and groove axis of no-feathering to being fixedly connected with, radial for being rotatably connected, pullover 1 head is provided with regular polygon through hole, and interior stud 4 is provided with axial regular polygon blind hole, and the regular polygon blind hole on interior stud 4 corresponds to the regular polygon through hole of pullover 1 head.
Be installed with regular polygon chalk 3 in regular polygon blind hole on the regular polygon through hole of pullover 1 head and interior stud 4, and the regular polygon through hole of pullover 1 head is connected with matched in clearance between regular polygon chalk 3.
Cover body 2 is broken cover body by two and half and is combined.Pullover 1 is made up of soft material.
Regular polygon through hole and regular polygon blind hole are square or regular pentagon or regular hexagon through hole and blind hole.
(1) chalk sleeve agent structure
Before chalk sleeve uses, cover body 2 is broken into two with one's hands, as Fig. 2 together with internal thread combines with chalk, then the appropriate location of the half of cover body 2 is put into, chalk 3 is made to expose cover body 2 sub-fraction, then build second half, install pullover 1 and cap bag 5 at cover body two, then hold the slightly top part of nib and just can write on blackboard.
In use procedure, rotate pullover 1, drive chalk 3 to rotate, and then drive externally threaded interior stud 4 to relatively rotate with the female cover body 2 of band, make interior stud 4 and chalk 3 precession and back-out by threaded function.
(2) dynamic structure
As shown in Figure 2, pullover 1 and chalk 3 be regular hexagon structure, pullover 1 regular hexagon through hole is a bit larger tham chalk 3 regular hexagon profile, thus when hand-screw moves pullover 1, provide power can to chalk 3 turn, be convenient to again moving radially of chalk 3.
As shown in Figure 3, chalk 3 and interior stud 4 endoporus are regular hexagon structure, and the torque passed in dynamic structure 1 can drive interior stud 4 to rotate.
(3) thread matching structure
As shown in Figure 4, the external screw thread of interior stud 4 and the screw-internal thread fit of cover body 2, under being driven by dynamic structure, stud 4 relatively rotates, by screw thread own characteristic relative to cover body 2, also internal thread can be made to produce move radially, thus realize precession and the back-out of chalk.
(4) pullover 1 with cover body 2 relatively rotate mechanism
As shown in Figure 5, cover body 2 diameter adopts the free ink pen cap for brush used and the tongue and groove structural design of a body in similar life, has so both been conducive to the installation of pullover 1 and cover body 2, and has been convenient to again both relatively rotating, provides power.
