Abstract
The utility model discloses a novel chalk assist device belonging to the technical filed of the guard group for the pen core point of chalk linker of holders for pencils and chalks of the subclass of writing or drawing device in the class of office appliance in writing and drawing appliance of the printing branch in the work and transportation part according to (International Classification of Patent for Invention) IPC. The aim is to solve the erodent problem on hands caused by calcium carbonate inside chalks. The utility model mainly comprises an upper cover, a lower cover, a clip, a spring and a pushing rod and is characterized in that: the pushing rod is positioned at a clamping position of the clip to form a cylindrical complete structure; the lower cover is inserted and installed inside the clamping position of the clip to form a cylindrical complete structure with the function of holding the lower part of the chalk. The upper cover contact and is installed at the upper part of the lower cover to form a cylindrical complete structure with the function of protecting the upper part of the chalk. The best way to realize the scheme is taking plastic as the material and using the base devices of the stationery factories to carry out production in batches, thereby meeting the demand of the teaching profession and realizing the practical and economical value of the novel chalk assist device.
Description
(-) technical field:
The utility model relates to the novel chalk assistor, divides by International Patent Classification (IPC) (IPC) to belong to operation Department of Transportation, and printing branch is write or drawing appliance; The big class of office appliance is write or the drawing appliance group clamper of pencil or chalk; The pencil connector; The protector technical group field 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 of reservoir tip was all done very fruitful effort to the demand of novel chalk assistor, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Liu Jianchun, Granted publication is CN2234359Y, China Patent No. (ZL) is: No. 95241682.4 utility model patent title is the utility model patent of " a kind of pencil combined type extension element ", the technical scheme that is adopted.Clamper at pencil or chalk; The pencil connector; The technical elements of the protector of reservoir tip is a routine of great value invention, and it has solved the technical problem of pencil with the combined type extension element effectively.But still have some deficits, it also is difficult to the technical problem of the corrosion of the calcium carbonate adversary in the solution chalk.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of novel chalk assistor.Technical problem with the corrosion that solves the calcium carbonate adversary in the chalk.
The novel chalk assistor that the technical scheme that the technical problems to be solved in the utility model adopted is achieved in that this utility model mainly by: on overlap, trap, clip, spring, catch bar constitute.Its major part spring is selected for use by market.Overlapping on it, trapping is drum, uses plastic material, through moulding processing and manufacturing.Its clip is a circle folder shape, uses plastic material, through moulding processing and manufacturing.Its catch bar is a cylindrical shape, uses plastic material, through moulding processing and manufacturing.
In shape, textural, the total essential features of novel chalk assistor of the present utility model and immediate prior art is: spring is put into the centre position that is installed in clip, constitutes weak spring shape overall structure, and function has been a pressuring action.In shape, textural, the novel chalk assistor of the present utility model technical characterictic different with immediate prior art is: catch bar is put into the Jia Kou position that is installed in clip, constitutes the cylindrical shape overall structure, and function has been to release the chalk effect.Trap and insert the Jia Kou position that is installed in clip, constitute the cylindrical shape overall structure, function has been to put into the chalk lower reaction.Last cover contact is installed in the upper position of trapping, and constitutes the cylindrical shape overall structure, and function has been the top effect of protection chalk.So just realized the purpose of the corrosion of the calcium carbonate adversary in the chalk of novel chalk assistor of the present utility model.
The beneficial effect of the novel chalk assistor of utility model is that the utility model is technical scheme that technical problem adopted and the clamper about pencil or chalk existing and that once had that solves the corrosion of the calcium carbonate adversary in the chalk; The pencil connector; The technology of the protector of reservoir tip has been compared a place's advantage and an improvement:
The first, owing to designed the shell type protective sleeve and controlled clip in the technical scheme of novel chalk assistor of the present utility model, so easy to use, can protect hand.
(4) description of drawings:
Accompanying drawing provides the structural representation of novel chalk assistor of the present utility model:
Fig. 1: the overall structure schematic diagram that is novel chalk assistor of the present utility model:
The label declaration of parts in the schematic diagram: cover 23 clips, 4 springs, 5 catch bars of trapping on 1
(5) specific embodiment:
Below in conjunction with accompanying drawing, be that the optimal way that realization solves the technical scheme that the technical problem of the corrosion of the calcium carbonate adversary in the chalk takes is described further to novel chalk assistor of the present utility model:
Its static structure: see also Fig. 1: as shown in the figure, novel chalk assistor of the present utility model mainly by last cover 1, trap 2, clip 3, spring 4, catch bar 5 constitute.Its major part spring 4 is selected for use by market.Going up cover 1, trapping of it 2 is drums, use plastic material, passes through and moulds processing and manufacturing.Its clip 3 is circle folder shapes, uses plastic material, through moulding processing and manufacturing.Its catch bar 5 is cylindrical shapes, uses plastic material, through moulding processing and manufacturing.
In shape, textural, the total essential features of novel chalk assistor of the present utility model and immediate prior art is: spring 4 is put into the centre position that is installed in clip 3, constitutes weak spring shape overall structure, and function has been a pressuring action.
In shape, textural, the novel chalk assistor of the present utility model technical characterictic different with immediate prior art is: catch bar 5 is put into the Jia Kou position that is installed in clip 3, constitutes the cylindrical shape overall structure, and function has been to release the chalk effect.2 insertions of trapping are installed in the Jia Kou position of clip 3, constitute the cylindrical shape overall structure, and function has been to put into the chalk lower reaction.1 contact of last cover is installed in 2 the upper position of trapping, and constitutes the cylindrical shape overall structure, and function has been that protection chalk top acts on.
Its dynamic structure: in the optimal way of implementing, in use, when writing, press clip 3 and clamp and trap 2 and chalk, open and overlap 1 and release chalk.According to mechanics principle, trapping of it 3 acts on clip 3 by spring 4, thereby finishes the task of clamping.According to mechanics principle, its catch bar 5 acts on by clip 3 and traps 3, thereby finishes the task of releasing chalk.So just realized the purpose of the corrosion of the calcium carbonate adversary in the chalk of novel chalk assistor of the present utility model.
Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of stationery factory, take to produce in batches,, so just can realize the practical value and the economic worth of novel chalk assistor of the present utility model better with the demand on supply teaching circle.
