Description

A kind of pen cap that finger position mark for holding pen is arranged

A kind of pen cap that finger position mark for holding pen arranged can support rapidly in use holds a correct method of holding, play anti-skidding, to alleviate finger tired, economizes on effects such as pen, the feasible more just power of writing.This technical field that the present invention belongs to is the stationery class.

It is the traditional Wood-bar pencil cap for brush that this invention is had the prior art of reference role.

My development has the pen cap purpose of finger position mark for holding pen:

1 is enclosed within the pen cap when using on the penholder, according to the marker radio beacon will on the pen cap, make people easily support correctly shake hands and refer to hold the finger position of pen.Can play good effect to the people that just learn to write.

2 can prevent that finger from sliding up and down when writing, make finger indefatigability when writing for a long time.

3 when holding according to the marker radio beacon will on the pen cap, can correct an incorrect in the past method of holding.

The 4 pairs of Wood-bar pencils are economized on the pen effect, when Wood-bar pencil makes finger be difficult for holding, write in the same old way freely by self length of the pen cap.

5 nibs contract and put the effect that can play traditional cap for brush when putting in people's pen cap.

6 these pen cap scope of applications are extensive, can be used for Wood-bar pencil, propelling pencil, marking pen, ball pen and pen etc.

A kind of pen cap that finger position mark for holding pen is arranged, by the hollow cylinder sleeve pipe, tube wall is made vertically third-class identical three slices watts of size that are divided into, between every watt, connect by elastomeric material that plays dilating effect or rubber, have respectively on every watt of pipe box one end that mother refers to, the finger-type trace concave surface of forefinger, middle finger, in concave surface or the next door numeral is arranged, the Warning Mark of Chinese character or color material is made up of horizontal anti-skidding crest line at internal surface of sleeve pipe.

It is characterized in that pen cap length is respectively 40mm, 70mm, 80mm; Wall thickness 0.6mm-2mm; Concave surface finger mark degree of depth 0.2mm-8.6mm; Anti-skidding rib 0.1mm * 0.1mm; Watt long with watt horizontal arc length be respectively 40mm * 15mm, 70mm * 15mm, 80mm * 15mm; The concave surface ovalize, middle finger minor axis 6mm is apart from pen cap end points 6mm; Forefinger major axis 13mm, apart from pen cap end points 5mm, mother refers to major axis 13mm, apart from pen cap end points 8mm.

A kind of manufacture method that the pen cap of finger position mark for holding pen is arranged:

The material of making the pen cap has materials such as polystyrene, polyvinyl chloride, polyethylene, polypropylene, ABS, polyamide, AS resin, rubber, copper, iron, aluminium, stainless steel.

Connect the pen cap and three slices watts two kinds of methods arranged:

The first: make the mould of corresponding specification according to the different size of the pen cap watt, done half lap scarf joint formula interface every watt of longitudinal edge inboard, the wide 2mm of interface, thick is half of jacket wall thickness.Do concave surface finger-type trace at the every outside one end, wherein the middle finger concave surface is horizontal ellipse, because concave surface is laterally in the outside that is the cylinder jacket wall, so major axis dimension need not be considered minor axis 6mm; The forefinger concave surface is vertical oval minor axis dimension and need not considers major axis 13mm; Mother refers to that concave surface is vertical ellipse, and minor axis dimension need not be considered, major axis 13mm.Three finger mark concave surfaces are the spherical crown shape.Use serial injection machine injection moldeds such as miniature high-speed precise injection machine or S2-30 type then.Make 40mm * 4mm, 70mm * 4mm, 80mm * 4mm strip shape body with rubber or other elastomeric material that griffith woodsorrel herb joins with cutter, thick is half of jacket wall thickness, use cyclochloride resin, the serial bonding agent of water base or rubber is bonding, the also available heat-sealing machine hot synthetic type of other elastomeric material.

Its two: when the mould of manufacturing watt, do not do the overlap joint interface, light 2mm, 25mm, 50mm at jacket wall concave surface one side, concave groove has been done at the 65mm place, wide 2mm, thick be half of jacket wall thickness, use serial injection machine moulding such as miniature high-speed precise injection machine or S2-30 type then.Use the size of corresponding concave groove again, the nontoxic rubber circle of diameter 7.5mm or other elastic material ring is bonding or hot synthetic type.Above dual mode can make the pen cap use on the penholder of thickness different size, and the scope of application of the pen cap is enlarged.When the finger mark concave surface changed in pen cap thickness, mother referred to, the distance between the forefinger, middle finger concave surface changes by correct proportions, to holding not influence of a method.

According to the common-use size of Wood-bar pencil and other kind, for reducing production costs, reduce manufacturing procedure, can make the one pen cap that connects without elastomeric material.When making mould, only need make concave surface numeral or Chinese character Warning Mark, the anti-skidding crest line of inwall.Back serial injection machine moulding such as miniature high-speed precise injection machine or S2-30 type.

When making the pen cap with metal material, make sleeve pipe with veneer reeling machine or lathe, the finger mark concave surface is made with milling machine or stamping machine in the back; When having done rubber and connected the pen cap, do the overlap joint interface with milling machine, planer after the usefulness all-purpose adhesive bonding.Can be made into the pen cap of different size according to preschool child, pupil, middle school student's finger size.

Advantage and good effect that invention is compared with prior art had;

When using the traditional cap for brush, have only the effect of protection nib, a correct method of holding is not had help.Use has the pen cap of finger position mark for holding pen, and the effect of traditional cap for brush is not only arranged, and also plays the effect of economizing on Wood-bar pencil.Importantly make people support the correct method of holding of holding easily by the finger mark sign on the pen cap.It is tired to prevent that people from pointing random mobile and finger up and down when writing, and can correct the incorrect in the past pen of holding and be accustomed to, and makes and writes more just power, and smoothness has neat handwriting.This pen cap is remarkable to the Wood-bar pencil effect, especially can play good effect to students in middle and primary schools and preschool child's use.This pen cap not only is suitable for the penholder of thickness different size, also can be used for propelling pencil, marking pen, ball pen and pen etc.

Accompanying drawing is pen cap three-view diagram, the expanded view that finger position mark for holding pen is arranged.
