Abstract

The utility model relates to a rotary three-core pencil which is composed of an entirety formed by connecting a pencil cap with a pencil point, an opening cap and an ejecting device and a pencil arm with a spring and pencil cores, and the pencil cores are connected with the ejecting device. The ejecting device is composed of a slide block which is connected with the pencil cores and respectively matched with the cam seat in the pencil cap and the slide block seat. As long as the pencil cap or the pencil arm is rotated, the utility model can quickly and accurately change different colors and different pencil cores for writing. The utility model has the advantages of compact structure, rigorous matching, small volume, portability and convenient use, and provides a new variety and design for market.

Description

Rotary type three core pens

Technical field

The utility model relates to a kind of Multi-refill ball-point pen, as long as rotate the pen cap or penholder, with regard to the pen core of interchangeable different colours or the dissimilar pen core rotary type three core pens for use.

Background technology

The function of existing commercially available pen and of a great variety, but adopt the pressing structure of traditional type to be used as ejecting mechanism more than the Multi-refill ball-point pen, constantly change different pen cores for using.

The patent No. 01245985.2 " Multi-refill ball-point pen ", after it also needs earlier penholder to be tilted and then is pressed and is pressed cap though a kind of Multi-refill ball-point pen also is provided, and changes different pen cores for using, and it is convenient not enough to use.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of rotary type three core pens are provided, make usefulness more than one, pen core transposing rapidly, carry, use more convenient, for market provides a kind of designs and varieties of selecting for the consumer.

The technical scheme in the invention for solving the above technical problem is: rotary type three core pens are by the integral body that has pen clip, presses cap, the pen cap of ejecting device and the penholder that band spring, pen core are installed connect into, and pen core and ejecting device connect and compose, described ejecting device is by the slide block that is connected on the pen core, respectively be installed in the pen cap in cam chair, take-up housing cooperate form.

Compared with prior art, advantage of the present utility model: so the ejecting device of three core pens, by the slide block that is connected on the pen core, cooperate with cam chair, take-up housing in the pen cap respectively form, its compact conformation cooperates tightly, so volume is little, carry, use more convenient, only need rotate the pen cap or penholder during use, accurate by the ejecting device in it, and rapidly required pen core is released for use, stable performance, reliable operation is for market provides a kind of new designs and varieties.

The specific embodiment

Embodiment is further described the utility model below in conjunction with accompanying drawing.

The horizontal positioning bar that two symmetries, protrusion are arranged on the take-up housing 8 upper end outer surfaces, the upper port periphery has three uniform breach, the lower end outer surface has a vertical positioning bar that protrudes, dividing plate 21 with three through holes is arranged between upper and lower end, take-up housing 8 under the dividing plate 21 is a screw, uniform, three convex tendon shifting blocks 22 separately, three grooves 23 are arranged on take-up housing 8 inwalls on the dividing plate 21, and three shifting blocks 22 and mouthful three breach of end are on same straight line.

Cam chair 5 upper ends are tubular, in the middle of the outer surface three uniform locating pieces 17 are arranged, and have embedded rubber 2 in the pipe end groove, and the two edges, lower end are the helix 18 of symmetry, and the intersection of helix 18 is the breach 19 of a circular arc.

The jacking block 20 that projection is arranged on one end of slide block 6 outer surfaces, its periphery are and helix 18 cooperations of cam chair 5 lower edge, corresponding helix.

On the pen cap 7 one end inwalls screw thread being arranged, and have and corresponding three grooves of take-up housing 8 mouthfuls of ends breach, is breach in 240 ℃ of scopes on the end wall in addition.

The two ends of penholder 13 tightly are with inline spiral shell 10 and point cover 16 respectively, it tightens and is with sheath 12, the pen core 15 of spring 9 will be with, pencil machine core 14 3 pen cores insert in three slide blocks, 6 inner chambers fixing respectively, pass the through hole on the take-up housing 8 again, jacking block 20 on each slide block 6 is aimed at corresponding groove 23 on the take-up housing 8, make its in groove on, following slippage, the take-up housing 8 that assembles is put into the breach end of the pen cap 7, make in the breach of vertical positioning bar on the pen cap 7 on the take-up housing 8 and rotate, and make take-up housing 8 ends of stretching out outside the pen cap 7 tightly be with centre circle 11, cam chair 5 is inserted 6 of take-up housings 8 and slide blocks, and the top of entangling three slide blocks 6, and three positioning bars 17 on cam chair 5 outer surfaces, join slippage up and down with the groove cunning on the pen cap 7, put pen clip 4 at the pen cap 7 end faces, with case ring 3 usefulness on it screw thread be fixed on the pen cap 7 ends, to press cap 1 tight the insertion in the case ring 3 again, pen cap assembly is assembled into, with the penholder 13 that has assembled, be fixed in the screw of take-up housing 8 lower ends with inline spiral shell 10, three core pens are assembled into.

During use, rotating the pen cap 7 rotates the cam chair 5 that links into an integrated entity with it, when the breach on it 19 just withstands jacking block 20 on the slide block 6, just this slide block 6 is down pushed away together with the pen core of being fixed 15, outside stretching out penholder 13, supply to write, three positioning bars 17 on the cam chair 5 are embedded in respectively in three breach of take-up housing 8 ports, as shown in Figure 2 simultaneously.

If will change pen core uses, at this moment rotate the pen cap 7 again, make cam chair 5 breach 19 leave slide block 6, the shifting block 22 on the take-up housing 8 is just run into the jacking block 20 on the slide block 6 that stretches out pen core 15 simultaneously, its overcome friction is moved up along cam chair 5 helixes 18, make in the pen core 15 withdrawal penholders 13.Another slide block 6 moves down with the helix 18 of pen core 15 along another side simultaneously, and in the jacking block on the slide block 6 20 was tipped the breach 19 of cam chair 5 ends in, then this pen core 15 just was pushed out penholder 13 for writing, and reaches the purpose that rapid transposing pen core Gong is write.
