Abstract

The utility model relates to a clean chalk sleeve with chalk conservation, which comprises an inner sleeve, an outer sleeve, an adjusting rotation sleeve and a chalk base, wherein the inner sleeve includes an upper pipe of the inner sleeve and a base of the inner sleeve; the outer sleeve is in sleeve joint with the upper pipe of the inner sleeve; the chalk base is arranged in the upper pipe of the inner sleeve and connected with the upper pipe of the inner sleeve in a sliding manner; and the adjusting rotation sleeve is sleeved outside the base of the inner sleeve. The clean chalk sleeve with simple structure can make full use of the chalk stump. By adjusting the ascending height of the chalk base in a rotating manner, the exposure length of the chalk can be adjusted accurately, conveniently and quickly. By adopting the clean chalk sleeve, the chalk can be firmly fixed in the sleeve and has low possibility of breaking, and meanwhile, the hand can keep clean.

Description

Save the cleaning powder pen cap tube of chalk

One, technical field: the utility model relates to a kind of cleaning powder pen cap tube of saving chalk.

Two, background technology: chalk is widely used in school and each office, unit, and especially in school, the teacher needs the writing on the blackboard that do not stop in giving lessons, with literal and figure instruction student.Chalk can produce dust in writing process, the finger of hand-held chalk usually is stained with dust.Chalk head after writing simultaneously is owing to be not easy to control, for not influencing teaching, the chalk head usually by teacher abandon need not, this just causes great waste.Though more chalk sleeve or folder tube are arranged now, though it can both play the effect of saving chalk, in writing process; chalk rocks easily; so through regular meeting the phenomenon of chalk fracture takes place, and regulating chalk, to expose the length of sleeve loaded down with trivial details relatively, delays the continuity of teaching.

Three, summary of the invention: the purpose of this utility model is to propose that a kind of adjusting is quick, convenient, and chalk is easy fracture not, can keep hand cleaning, utilizes the cleaning powder pen cap tube of the saving chalk of chalk head to greatest extent.

The purpose of this utility model is achieved in that the cleaning powder pen cap tube of saving chalk, form by inner sleeve, outer sleeve, adjusting rotation set and chalk seat, inner sleeve is made up of pipe and inner sleeve base on the inner sleeve, pipe box connects on outer sleeve and the inner sleeve, the chalk seat places on the inner sleeve in the pipe, be slidingly connected with it, outside the inner sleeve base, be with the adjusting rotation set.

The utility model is simple in structure, the chalk head can be utilized to greatest extent.By the lifting height of rotation adjusting chalk seat, can accurately regulate chalk exposure length, it is easy to adjust, quick.Chalk is fixed in sleeve, and easy fracture can not keep hand cleaning simultaneously.

Four, description of drawings: concrete structure of the present utility model is provided by following drawings and Examples:

Fig. 1 is a cleaning powder pen cap barrel structure schematic diagram of saving chalk;

Fig. 2 is the inner sleeve structural representation;

Fig. 3 is the outer sleeve structure schematic diagram.

Legend: 1, outer sleeve, 2, manage on the inner sleeve, 3, long chute, 4, regulate rotation set, 5, the inner sleeve base, 6, positioning tooth, 7, contact pin, 8, the chalk seat, 9, card, 10, transverse slat, 11, short groove, 12, spring, 13, the card rib, 14, slide bar, 15, spiral chute.

Five, the specific embodiment:

The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.

Embodiment: as Figure 1-3, save the cleaning powder pen cap tube of chalk and form by inner sleeve, outer sleeve 1, adjusting rotation set 4 and chalk seat 8.

Outer sleeve 1 is a cavity pipe, is provided with a circle positioning tooth 6 in its outer wall bottom.Have a circle draw-in groove at outer sleeve 1 inwall downside, the inwall of draw-in groove upside be provided with two relative, along outer sleeve 1 spiral inner wall coiling spiral chute 15 upwards.

Inner sleeve is by cavity inner sleeve base 5 and be fixed on the inner sleeve of inner sleeve base 5 upper surfaces pipe 2 and form.On the tube wall of pipe 2 on the inner sleeve, have two relative vertical long chutes 3, be plugged with chalk seat 8 in the pipe 2 on the inner sleeve, chalk seat 8 is the uncovered cavity pipe in upper end, bottom center is provided with contact pin 7 within it, chalk seat 8 outer walls two opposite face places are provided with slide bar 14, slide bar 14 is through at respectively in the two long chutes 3, and the end is positioned at spiral chute 15, and pipe 2 is slidingly connected on chalk seat 8 and the inner sleeve.Be provided with the outstanding card rib 13 of a circle on pipe 2 outer wall on the inner sleeve that is positioned at long chute 3 downsides, card rib 13 is stuck in the draw-in groove on aforementioned outer sleeve 1 inwall, and pipe 2 forms sockets on outer sleeve 1 and the inner sleeve, and is free to rotate between the two.

Be sheathed with outside inner sleeve base 5 and regulate rotation set 4, regulating rotation set 4 is a pipe, and it is wide down to be connected with on relative card 9, two cards 9 point in its sidewall upper, and the tip places between the teeth of positioning tooth 6.

On the opposite, have vertical short groove 11 at inner sleeve base 5 sidewalls, 11 of two short grooves are inserted with transverse slat 10, transverse slat 10 two ends are connected with adjusting rotation set 4 inwalls, and center, transverse slat 10 lower surface is provided with spring 12, and spring 12 end in addition is connected with the bottom surface of inner sleeve base 5.

During use, the chalk head is inserted in the chalk seat 8, fixing by contact pin 7, when the card 9 of regulating rotation set 4 was stuck between the teeth of positioning tooth 6, outer sleeve 1 can't rotate, and the chalk seat 8 of this moment is fixed.When needing to regulate the position of chalk seat 8, pinch outer sleeve 1 on the other hand, the another hand will be regulated rotation set 4 and spur downwards, after treating that card 9 withdraws from positioning tooth 6, get final product turn outer sleeve 1,1 promotion slide bar 14 of the outer sleeve of turn moves up or down, drives chalk seat 8, thereby regulates the exposure length of chalk head.

Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characterictic according to actual needs, satisfies the needs of different situations.
