Description

The novel pencil head connector

(1) technical field:

The utility model relates to the novel pencil head connector, 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, the clamper of pen 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 pen or chalk; The pencil connector; The technology of the protector of reservoir tip was all done very fruitful effort to the demand of novel pencil head connector, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Liu Jianchun, Granted publication number is CN2234359Y, China Patent No. (ZL) is: No. 95241682.4 utility model title is the utility model patent of " a kind of pencil combined type extension element ", the technical scheme that is adopted.Clamper at pen or chalk; The pencil connector; The protector technical elements of reservoir tip is a routine of great value invention, and it has solved the technical problem of pencil combination extension element effectively.But still have some deficits, it also is difficult to the solution pencil stub because of connecting the technical problem that lengthening is continued utilization.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of novel pencil head connector.To solve pencil stub because of connecting the technical problem that lengthening is utilized by continuation.

The novel pencil head connector 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: at the bottom of nib, nib, penholder, the penholder, taper sheath, pen container constitute.Be cylinder material at the bottom of its penholder, the penholder, use wood material, through the machined manufacturing.Its pen container is a cylindrical shape, and outer circle diameter 1.1-1.3cm is long to use plastic material for 6-8cm, through the machined manufacturing.Its taper sheath is a cone shape, and drilling is processed in pen container rain end, and tapered indent circular groove becomes one with pen container, and little outer big in the taper grooving internal diameter, outer bore 0.8-1cm, interior bore are 0.5-0.7cm, taper sheath depth 2-2.5ccm.Its pen container is a cylindrical shape, uses plastic material, through the machined manufacturing.

In shape, textural, the total essential features of novel pencil head connector of the present utility model and immediate prior art is: the pen container interference fit is installed in the end position of penholder, constitutes cylindrical shape pen container structure, and function has been to support the penholder effect.In shape, textural, the novel umbrella formula Air inflation rain cape of the present utility model technical characterictic different with immediate prior art is: written hand cutter is cut the front position that is formed on penholder, constitutes cone shape nib structure, and function has been the effect that shows pen core gradually especially.Interference fit is installed in the center of taper sheath at the bottom of the penholder, constitutes the cylindrical shape over-surplus fit structure, and function has been to fix to clamp the connection effect.The pen container interference fit is installed in the end position of penholder, constitutes cylindrical shape pen container structure, and function has been to support the penholder effect.Continued the purpose of the technical problem of utilization like this because of the connection lengthening with regard to the solution pencil stub of having realized novel pencil head connector of the present utility model.

The beneficial effect of the novel pencil head connector of utility model is that the utility model is for solving pencil stub because of connecting lengthening by technical scheme that continues to utilize technical problem to adopt and the clamper about pen or chalk existing and that once had; The pencil connector; The technology of the protector group of reservoir tip has been compared three place's advantage and improvement:

The first, owing to designed nib in the technical scheme of novel pencil head connector of the present utility model, so easier solution shows the technical problem of pen core gradually especially.

The second, owing to designed penholder in the technical scheme of novel pencil head connector of the present utility model, so easier solution fixes to clamp the technical problem of connection.

The 3rd, owing to designed pen container in the technical scheme of novel pencil head connector of the present utility model, the technical problem of penholder is supported in easier solution.

The label declaration of parts in the schematic diagram: 5 taper sheaths, 6 pen containers at the bottom of 1 nib, 2 written 3 penholders, 4 penholders

(5) specific embodiment:

Below in conjunction with accompanying drawing, novel pencil head connector of the present utility model is described further for the optimal way that realization solves the technical scheme that pencil stub takes because of the technical problem that connects lengthening and continued to utilize:

Its static structure: please join accompanying drawing: as shown in the figure, novel pencil head connector of the present utility model mainly by at the bottom of nib 1, nib 2, the penholder 3, penholder 4, taper sheath 5, pen container 6 constitute.At the bottom of its penholder 3, the penholder is 4 cylinder material, uses wood material, through the machined manufacturing.Its pen container 6 is cylindrical shapes, and outer circle diameter 1.1-1.3cm is long to use plastic material for 6-8cm, through the machined manufacturing.Its taper sheath 5 is cone shapes, and drilling is processed in pen container rain end, and tapered indent circular groove becomes one with pen container 6, and is little outer big in the taper grooving internal diameter; Outer bore 0.8-1cm, interior bore are 0.5-0.7cm, taper sheath 5 depth 2-2.5ccm.Its pen container 6 is cylindrical shapes, uses plastic material, through the machined manufacturing.

In shape, textural, the total essential features of novel pencil head connector of the present utility model and immediate prior art is: pen container 6 interference fit are installed in the end position of penholder 3, constitute cylindrical shape pen container structure, and function has been to support the penholder effect.In shape, textural, the novel pencil head connector of the present utility model technical characterictic different with immediate prior art is: written 2 hand cuttves are cut the front position that is formed on penholder 3, constitute toroidal nib structure, and function has been the effect that shows pen core gradually especially.3 end of penholder interference fit is installed in the center of taper sheath 5, constitutes the cylindrical shape over-surplus fit structure, and function has been to fix to clamp the connection effect.Pen container 6 interference fit are installed in the end position of penholder 3, constitute cylindrical shape pen container structure, and function has been to support the penholder effect.

Its dynamic structure: in the optimal way of implementing, in use, when nib is too little, then need to take out pen container 6,, make its clamping then, at this moment can use this little written 2 to write, draw a picture with 4 embedding in the pen containers 6 at the bottom of the penholder along taper sheath 5.

Its dynamic structure: in the optimal way of implementing, in use, when simultaneously two nibs being arranged, with another nib 2, by same quadrat method, in the taper sheath 5 of embedding pen container 6 slowly, make clamping, at this moment, obsolete pen ice can both have been used on two.Continued the technical problem purpose of utilization with regard to the traditional pencil stub of the solution that has realized novel pencil head connector of the present utility model because of connecting to extend like this.

Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of machined factory, take to produce by batch,, so just can realize the practical value and the economic worth of novel pencil head connector of the present utility model better with the demand of supply student circle.
