Abstract

Chalk protection box its objective is that solving chalk burns hand, and the chalk head is not write the problem of word.It mainly is made of knob, housing, slide block, chalk folder, guide rail, chalk, anti-sliding sleeve.It is characterized in that: the outer rim of guide rail is inserted in the hole of slide block, and the external screw thread place of slide block is threaded in the internal thread of housing, and the inner chamber of anti-sliding sleeve is enclosed within the lower part of frame outer rim, and the upper end Ka Chu of housing is stuck on the lower end card of knob.Utilize the equipment of plastic processing factory, mass production is with the demand of supply educational circles.

Description

Chalk protection box
(1) technical field:
The utility model relates to chalk protection box, divides the clamper that belongs to pencil or chalk by International Patent Classification (IPC) (IPC); The pencil connector; The technical field of the protector group of reservoir tip.
(2) background technology:
At present, the clamper that has now and once had about pencil or chalk; The pencil connector; The technology of the protector group of reservoir tip was all done very fruitful effort to the needs of chalk protection box, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Li Guobin, Granted publication is that CN2222067Y China Patent No. (ZL) is: ZL95242994.2 number utility model patent title is the utility model patent of " locating chalk sleeve automatically ", the technical scheme that is adopted is at the clamper of pencil or chalk; The pencil connector; The technical elements of the protector group of reservoir tip is a routine of great value invention, and it has solved chalk sleeve effectively and has located automatically, the convenient technical problem of using.But still have some deficits, it also is difficult to solve chalk and burns hand, and the chalk head is not write the technical problem of word.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of chalk protection box.Burn hand to solve chalk, the chalk head is not write the technical problem of word.
The new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is: chalk protection box of the present utility model mainly is made of knob, housing, slide block, chalk folder, guide rail, chalk, anti-sliding sleeve.
In shape, structure and combination thereof; the total essential features of chalk protection box of the present utility model and immediate prior art is: the lower surface of slide block is bonded at the upper surface of chalk folder; the following folder place of chalk folder is clipped in the top outer rim of chalk; the structure that is combined into one, function has been the effect of chalk.In shape, structure and combination thereof; the chalk protection box of the present utility model technical characterictic different with immediate prior art is: the outer rim of guide rail is inserted in the hole of slide block; the external screw thread place of slide block is threaded in the internal thread of housing; be combined into the integrative-structure of cylindrical shape, function has been the effect of rotary extension.The inner chamber of anti-sliding sleeve is enclosed within the lower part of frame outer rim, and the upper end Ka Chu of housing is stuck on the lower end card of knob, and the structure that is combined into one, function have been effects anti-skidding, rotation.The chalk that has so just reached chalk protection box of the present utility model burns hand, and the chalk head is not write the purpose of word.
The beneficial effect of the chalk protection box of utility model is that the utility model is to solve chalk to burn hand, and the chalk head is not write the technical scheme that technical problem adopted and the clamper about pencil or chalk existing and that once had of word; The pencil connector; The technology of the protector group of reservoir tip has been compared two place's advantage and improvement:
First; because the outer rim that has designed guide rail in the technical scheme of chalk protection box of the present utility model is inserted in the hole of slide block; the external screw thread place of slide block is threaded in the internal thread of housing, is combined into the integrative-structure of cylindrical shape, so the technical problem of easier solution rotary extension.
Second; be enclosed within the lower part of frame outer rim owing to designed the inner chamber of anti-sliding sleeve in the technical scheme of chalk protection box of the present utility model; the upper end Ka Chu of housing is stuck on the lower end card of knob, and the structure that is combined into one is so easier solution is anti-skidding, the technical problem of rotation.
(4) description of drawings:
Accompanying drawing provides the structural representation of chalk protection box of the present utility model:
Fig. 1: the overall structure schematic diagram that is chalk protection box of the present utility model;
The label declaration at each position in the schematic diagram:
1 knob, 2 housings, 3 slide blocks, 4 chalks folder
5 guide rails, 6 chalks, 7 anti-sliding sleeves
(5) specific embodiment:
Below in conjunction with accompanying drawing, for realizing that solving chalk burns hand, the optimal way that the chalk head is not write the technical scheme that the technical problem of word takes is described further to chalk of the present utility model protection box:
Its static structure: see also accompanying drawing: as shown in the figure, chalk protection box of the present utility model mainly is made of knob 1, housing 2, slide block 3, chalk folder 4, guide rail 5, chalk 6, anti-sliding sleeve 7.Its major part chalk folder 4, guide rail 5, chalk 6, anti-sliding sleeve 7 are selected for use by market.Its knob 1 is cylinder (anti-skidding line in addition) shape, is material with plastics, through the processing and forming manufacturing.Its housing 2 is cylindrical shell (internal thread) shapes, is material with plastics, through the processing and forming manufacturing.Its slide block 3 is cylinder (external screw thread) shapes, is material with plastics, through the processing and forming manufacturing.
In shape, structure and combination thereof; the total essential features of chalk protection box of the present utility model and immediate prior art is: the lower surface of slide block 3 is bonded at the upper surface of chalk folder 4; the following folder place of chalk folder 4 is clipped in the top outer rim of chalk 6; the structure that is combined into one, function has been the effect of chalk.In shape, structure and combination thereof; the chalk protection box of the present utility model technical characterictic different with immediate prior art is: the outer rim of guide rail 5 is inserted in the hole of slide block 3; the external screw thread place of slide block 3 is threaded in the internal thread of housing 2; be combined into the integrative-structure of cylindrical shape, function has been the effect of rotary extension.The inner chamber of anti-sliding sleeve 7 is enclosed within the bottom outer rim of housing 2, and the upper end Ka Chu of housing 2 is stuck on the lower end card of knob 1, and the structure that is combined into one, function have been effects anti-skidding, rotation.
Below by using method; further set forth chalk protection box dynamic structure relation of the present utility model: in use; when needs stretch chalk; according to spiral principle; at first screw out chalk folder 4; folder is gone up chalk 6 then, more then cycle to the appropriate location, thereby finish the task of flexible chalk.
In use, when needs write with the chalk head, according to spiral principle, at first screw out chalk folder 4, folder is gone up chalk head 4 then, catches anti-sliding sleeve 7 to write again then, thereby finishes the task of writing with the chalk head.The chalk of so just having realized chalk protection box of the present utility model burns hand, and the chalk head is not write the technical scheme of the technical problem of word.
Realize that preferred plan of the present utility model is is material with plastics; utilize the basic equipment of plastic processing factory; take mass production,, so just can realize the practical value and the economic worth of chalk protection box of the present utility model better with the demand of supply educational circles.
