Abstract

The utility model relates to the technical field of drawing tools, in particular to a drawing pen. The drawing pen comprises a pen sleeve and two pen refills installed on the pen sleeve. The pen sleeve is provided with a fixed pen refill hole and an adjustable pen refill hole, wherein the fixed pen refill hole and the adjustable pen refill hole are used for fixing the pen refills. A sleeve hole communicated with the adjustable pen refill hole is formed between the adjustable pen refill hole and the fixed pen refill hole. An elastic element is installed in the sleeve hole, wherein one end of the elastic element is connected with a protective sleeve, and the protective sleeve is matched with an adjustment element disposed on the side wall of the adjustable pen refill hole so as to fixedly clamp the pen refills. The two pen refills are assembled through the arranged adjustable pen refill hole and the fixed pen refill hole, the width between the two pen refills is adjusted through the adjustment element and compression and release of elasticity of the elastic element; when one pen refill needs to be replaced in the drawing process, what is needed is to take off the original pen refill and replace the original pen refill with a new pen refill, the pen refills of different line diameters can be used, and drawing requirements of lines of different diameters and walls of different thicknesses can be met in the drawing process; the drawing pen is simple in structure and convenient to use and has strong practicability.

Description

Drawing pen

Technical field

The utility model relates to drawing instrument technical field, especially drawing pen.

Background technology

At present, students or engineers and technicians are when completing the operations such as Architectural Graphing or mechanical drawing, the common drawing pen of general employing, as: Pencil with 2B hardness etc., this drawing pen wire diameter is single, adjustability is poor, is wire diameter, the structure that meets drawing, the frequent change-fountain pen of requirement needs of parts in drawing course; Especially when drawing the body of wall of architectural drawing, usually use one-pen to repeat multipass and draw the body of wall of different-thickness, workload is large and can't accurate Drawing, thereby often causes the problems such as job schedule is slow; Given this, need a kind ofly can disposablely to draw out different wall thicknesses, can require change according to wire diameter the drawing pen of pen core.

Summary of the invention

For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide the Novel double-core drawing pen of the live width between a kind of simple in structure, two lines of capable of regulating.

To achieve these goals, the utility model adopts following technical scheme:

Drawing pen, it comprises the pen cap and two pen cores that are installed on the pen cap, be provided with on the described pen cap for fixedly fixed core hole and the adjustable core hole of pen core, be provided with the trepanning that is communicated with the adjustable core hole between described adjustable core hole and fixed core hole, in described trepanning, elastic component is installed, one end of described elastic component is connected with sheath, and described sheath coordinates the regulating part that is installed on the sidewall of adjustable core hole that pen core is fixedly clamped.

Preferably, described regulating part comprises screw rod, regulates cap and retaining wall, and described adjusting cap runs through the adjustable core hole by screw rod sidewall is connected with retaining wall, and described retaining wall coordinates sheath that pen core is fixedly clamped.

Preferably, be provided with the live width scale on described adjusting cap.

Owing to having adopted such scheme, the utility model is assembled two pen cores by the adjustable core hole and the fixed core hole that arrange, by elastic force compression and the release of regulating part and elastic component, carries out two width adjustment between pen core; While needing to change pen core in drawing course, only need former pen core is taken off replacing, can use the pen core of different wire diameters, need in the drawing course to have guaranteed to draw the requirement of the body of wall of the lines of different wire diameters and different-thickness; It is simple in structure, and is easy to use, has very strong practicality.

Description of drawings

Fig. 1 is the structural representation of facing of the utility model embodiment;

Fig. 2 is the plan structure schematic cross-section of the utility model embodiment.

The specific embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.

As depicted in figs. 1 and 2, the Novel double-core drawing pen of the present embodiment, it comprises the pen cap 10 and two pen cores 20 that are installed on the pen cap, is provided with on the pen cap 1 for the fixed core hole 11 that respectively two pen cores 20 is fixed and adjustable core hole 12; Wherein, the aperture in fixed core hole 11 is less than the aperture in adjustable core hole 12.

Be provided with the trepanning 13 that is communicated with adjustable core hole 12 between adjustable core hole 12 and fixed core hole 11, elastic component 14 is installed in trepanning 13, elastic component 14 is selected the parts such as spring; One end of elastic component 14 is connected with the sheath 15 that is positioned at adjustable core hole 12; For realizing the wherein fixing purpose of one-pen core 20, it also is provided with the regulating part that is comprised of screw rod 16, adjusting cap 17 and retaining wall 18, adjusting cap 17 runs through adjustable core hole 12 by screw rod 16 sidewall is connected with retaining wall 18, and retaining wall 18 and sheath 15 are at the clamping device of the interior formation pen core 20 in adjustable core hole 12; Thus, regulate cap 17, utilize the screw thread feeding of screw rod 16 carry out the elastic force compression of elastic component 14 or discharge by rotation, and then realize two distance adjustment between pen core 20.

Plot Work for convenience of student or engineers and technicians, avoid causing slowing down of job schedule because automatically adjusting live width, regulating on cap 17 the live width scale that is provided with between two lines, as: the live width scales such as 0.6mm, 1.2mm, 1.8mm, 2.4mm, 3.0mm, 3.6mm are set according to the distance between the nib of two pen cores 20, so, the user only needs can adjust fast live width between two lines according to the live width scale; Simultaneously, the user can require the quick-replaceable pen core according to the wire diameter of different lines, has accelerated greatly speed and the precision of drawing; It is simple in structure, easy to use, and is practical.

The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
