Description

Multi-refill adjustable ball-point pen

The utility model belongs to and is used to the instrument writing or paint in the culture and education articles for use.

Current, the propelling pencil of each class formation and garden pearl oil pike have become people's study, the indispensable instrument of working, and be well received.But, in existing numerous type of activity pencils, the penholder of every kind of propelling pencil can only adapt to, the lead for retractable pencil of a kind of specification of clamping, the use of every kind of propelling pencil is restricted, as want to have the propelling pencil of several specifications, and also just must the complete outfit of several propelling pencils, cause and use and the inconvenience of carrying, obviously, purchase cost is also with regard to corresponding improve.It is also a lot of to be assemblied in same the garden pearl kind in the oil pike bar simultaneously as for several color wicks, but the movable pen that integrates lead for retractable pencil and wick still belongs to blank.

The purpose of this utility model is exactly that a kind of not only being applicable to of design write, but also is applicable to the adjustable movable pen of multicore of drawing, make its can be in same penholder the lead for retractable pencil of some kinds of specifications of clamping simultaneously, or the lead for retractable pencil of several specifications and varicolored wick be assemblied in same the movable pen, again can be according to using needs arbitrarily to adjust, select any lead for retractable pencil or wick, and definite its collapsing length at the penholder head, the needs of writing, paint to adapt to reach the purpose of using more.

Basic design of the present utility model is, this multicore is adjustable movable pen is by preceding cap, penholder, storage core pipe, back cap and tail-hood assembling constitute, its preceding cap is installed in the penholder front portion by thread connection, and the opening or shrink of the elastic claw formula garden arc card of control penholder front portion, the storage core pipe that has several different size storage core holes is configured in the penholder inner chamber, be located by penholder and back cap, simultaneously, guaranteeing has the core hole of going into of a storage core hole and penholder to align on the storage core pipe all the time, the wave-like and the penholder inwall cambered surface elasticity card of storage core tube outer surface constitute the device that fixes, utilize penholder adjusted mouth rotation storage core pipe, determine lead for retractable pencil or the wick selected by peep hole.

The utlity model has simple in structure, multicore, more than one with, applicability advantage wide, easy to use, with low cost.

Fig. 2 is the A-A profile of Fig. 1;

Fig. 3 is the B-B profile of Fig. 1, promptly stores core pipe cross section structure and penholder and regulates mouth, peep hole schematic diagram;

Fig. 4 is the C-C profile of Fig. 1, and the device schematic diagram promptly fixes;

Fig. 5 is the location of another form device schematic diagram that fixes.

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.Multicore is adjustable movable pen is by preceding cap 1, penholder 2, storage core pipe 3, back cap 4 and tail-hood 5 constitute, assembly relation is as follows: by interior, externally threaded connecting relation is installed in preceding cap 1 front portion of penholder 2, and the outer cone of the elastic claw formula garden arc card of the endoporus of cone shape and penholder 2 front portions was complementary in preceding cap 1 was, control opening or shrinking of elastic claw formula garden arc card, make of transparent material, the storage core pipe 3 that both ends of the surface have rotating shaft is configured in penholder 2 inner chambers, the rotating shaft of its storage core pipe 3 lower surfaces inserts in the pit of penholder 2 inner chambers, the rotating shaft of upper surface matches with the pit of the back cap 4 that is assemblied in penholder 2 rear ends, to store core pipe 3 locatees in penholder 2, simultaneously, all the time there are a storage core hole 7 and the core hole 6 of going into of penholder 2 to align on the storage core pipe 3, dead in line, tail-hood 5 spiral-locks are so far formed the adjustable movable pen of multicore on the cap 4 of back.On penholder 2, be provided with the adjusting mouth 10 of two symmetric arrangement, and peep hole 9.Processing at the garden week place that is positioned at storage core pipe 3 center lines same radius size that several axis are parallel, the storage core hole 7 of different size, the inner chamber pit centres line of this radius size and penholder 2 and the distance of going between the center line in core hole 6 are measure-alike, and storage core pipe 3 outer surfaces are the wave-like of being made up of the garden curved stroke.By the wave-like of the storage core pipe 3 outer surfaces location that is configured for selecting a core and the fixation device 8 that fixes that matches with penholder 2 inwall cambered surface elasticity cards.Tail-hood 5 internal fixation are installed with pocket knife 11 and rubber 12.

During use, back cap 4 is screwed off from penholder 2, with different size, the lead for retractable pencil of different colours and wick are put into the corresponding storage core hole 7 of storage core pipe 3, screw on back cap 4, erect penholder 2, make back cap 4 one ends be positioned at the below, in the gravity effect, all lead for retractable pencils in the storage core pipe 3 and wick all fall into storage core hole 7 (going into no lead for retractable pencil and wick in the core hole 6 this moment), utilize and regulate mouthful 10 rotation storage core pipes 3, behind peep hole 9 definite selected lead for retractable pencils or wick, stop operating, by the location fixing storage of the device 8 core pipes 3 that fix, the storage core hole 7 that this fashionable dress the lead for retractable pencil of required use or wick with go into core hole 6 and align, with preceding cap 1 one ends down, enter in the core hole 6 with the lead for retractable pencil or the wick of going in the storage core hole 7 that core hole 6 aligns, the elastic claw formula garden arc card size of penholder 2 is adjusted in the position of cap 1 on penholder 2 before changing, lead for retractable pencil or wick are clamped after core hole 6 front ends stretch out certain-length from going into of penholder 2, can use.When changing core, back cap 4 one ends unclamp elastic claw formula garden arc card down, and core hole 6 interior lead for retractable pencils or wick are fallen in the storage core hole 7, and rotation storage core pipe 3 repeats aforementioned process.
