Description
Technical field
The utility model relates to carpenter's pencil, is a kind of plug-type carpenter's pencil.
Background technology
Carpenter's pencil be a kind of pen core and a body all in flat, or the pencil of a wherein body ovalize, it is mainly used in the drafting that timber cutting etc. adds lines in man-hour.Traditional carpenter's pencil is identical with pencil, is made up of graphite pen core and wood pen holder, while cutting penholder, nib is machined to be convenient to the length of ruling and shape by instruments such as penknives.But in order to the Reusability of a body and being convenient for changing of pen core, some producers improve carpenter's pencil structure; As the patent No. ZL200920116867.8 disclosed in Chinese patent literature, authorized announcement date on January 27th, 2010, utility model title " a kind of Multifunctional marking pen "; This metal marker comprises one and has the pen core that a shell of hollow housing and Qi Nei be provided with, and it is characterized in that: a described shell offers gathering sill, two edges of gathering sill are provided with draw-in groove, are provided with the pushing handle matched with it in described gathering sill.Pen core is arranged in a shell and contacts with pushing handle, when pen core head because of use shorten after, utilize pushing handle that pen core is pushed away forward, until pen core is painted completely, pen core utilization rate is higher, and during use, hand is grabbed on a shell, the pen core be not made with tailor's chalk directly contacts, thus use procedure comparatively health, pen core can make identical thickness, the line even thickness thus drawn.But the location structure of above-mentioned pen core not detailed description, simultaneously its structure such as body, push button and parts also need further Improvement and perfection.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model provides a kind of plug-type carpenter's pencil, makes it solve existing like product overall construction design not good enough, and positioning and locking structural design, use comparatively inconvenience technical problem.Its objective is and to be achieved through the following technical solutions.
A kind of plug-type carpenter's pencil, a shell for this carpenter's pencil is provided with centre bore, and one end of centre bore is open pore, the other end is reservoir hole, and the leading flank of a shell is provided with slide rail hole, and slide rail hole communicates with the openend of reservoir hole, openend and the bonnet of shell fasten, and the pen core nose end of a shell is tapered; Thus pen core and positioning component can be loaded in a shell by opening bonnet, and change pen core.Its structural design main points are that the symmetrical dual-side notch in slide rail hole of described shell is respectively equipped with in step-like two sections of track limits, and the outside track limit of one section of both sides, slide rail hole is arranged with draw-in groove limit respectively; The pen core cover of positioning component is arranged in the centre bore of a shell, and the keeper of positioning component one end is limited in the inner orbit limit in slide rail hole, and positioning component is fastened by the draw-in groove limit on keeper and outside track limit; One end of pen core and the pen core of positioning component overlap one end fit, and keeper is arranged at the other end of pen core cover, and the other end of pen core stretches out the reservoir hole of a shell.Thus above-mentioned pen core is stretched out reservoir hole or retracts in a shell by the slip of positioning component on slide rail hole, be specially: after pen core extension elongation is suitable, by the position of keeper locking positioning assembly on slide rail hole of positioning component; When unclamping keeper, positioning component can drive pen core to be free to slide.The keeper of above-mentioned positioning component can be following pushing button structure, also can be existing knob structure, and other structures, as long as make positioning component be fixed on the limit notch in slide rail hole by keeper.Meanwhile, as long as this carpenter's pencil changing graphite pen core for cutting out pen core (white pen core), namely can be used as and cutting out detail pen use.
The keeper of described positioning component is push button, push button is connected with cage knob, connecting place is respectively equipped with symmetrically arranged interlocking shell fragment, the mutual fit of interlocking shell fragment of push button and cage knob, the end of interlocking shell fragment is respectively equipped with plush copper, the both sides plush copper of a wherein interlocking shell fragment of push button or cage knob is relative with the draw-in groove on draw-in groove limit, slides in the inner orbit limit that cage knob is limited in slide rail hole.Like this, as long as oppositely promote cage knob, the interlocking shell fragment of push button and cage knob can be made to be interacted by plush copper, thus move respectively to outside, and the plush copper in outside and draw-in groove limit are offseted, thus make the locking position of positioning component; When cage knob pushes back to push button side, push button is moved on slide rail hole by the stressed positioning component that can drive.
On the interlocking shell fragment of described push button, plush copper is respectively inside and outside both sides projection, and on the interlocking shell fragment of cage knob, plush copper is respectively interior both sides projection, and the interlocking shell fragment of cage knob is placed on inside the interlocking shell fragment of push button.Said structure also realizes the locking of push button by the movement of cage knob and unclamps.
The push button of described positioning component and pen core overlap one-body molded.Push button and the pen core cover of positioning component are shaping by a body technique, or are integrated by assembly.
The pen core cover end of described pen core is arranged with groove, and the protruding screens in the groove of pen core and pen core overlap fastens.Said structure is convenient to fixing on pen core cover of pen core, thus when preventing positioning component from moving, pen core and pen core overlap and depart from.
The pen core nose end of described shell is provided with holding section.When holding section is longer, this carpenter's pencil is comparatively easily held use.
The side of described shell is provided with Pencil lead box.Pencil lead box is arranged at a shell, thus is convenient to the replacing of pen core, and Pencil lead box access together with this carpenter's pencil.
The bonnet end of described shell or the trailing flank of bonnet are provided with pen clip.Pen clip is convenient to carrying of this carpenter's pencil, is namely convenient to this carpenter's pencil and is hung on work clothes pocket and pocket.
The utility model reasonable in design, use, easy to assembly, good stability during use; Be suitable as carpenter's bow pen or cut out detail pen and use, ex hoc genus anne the further improvement of product.
