Abstract

The invention provides an art pencil allowing a pencil lead to be adjusted conveniently and belongs to the technical field of pencil making. The art pencil comprises a pencil rod, the pencil lead arranged in a cavity of the pencil rod, a pencil plug arranged at the upper end of the pencil rod, and a pencil tip sleeve arranged at the lower end of the pencil rod. The pencil tip sleeve penetrates through a pencil lead tip part and is in threaded connection with the lower end of the pencil rod. The art pencil is characterized in that a pencil lead propelling tube is arranged in the cavity of the pencil rod, and an internal thread is arranged on the inner wall of a cavity of the pencil lead propelling tube; the pencil lead is cylindrical, the side wall of the pencil lead is provided with an external thread matched with the internal thread, and the pencil lead is in threaded connection with the interior of the pencil lead propelling tube. The art pencil is ingenious in design, simple in structure, easy to manufacture and low in cost; the pencil lead cannot be broken, the usage rate of the pencil lead is high, resources are saved, and environmental friendliness is achieved; the art pencil has broad market space.

Description

A kind of art pencil being convenient to adjustment pen core

Technical field

The present invention relates to a kind of structure being convenient to the art pencil regulating pen core, belong to pen technology field processed.

Background technology

Wooden and paper-roll pencil is write conveniently to people's work, learning tape, but consumes again a large amount of valuable forest reserves simultaneously.Existing wooden and paper-roll pencil needs volume to cut penholder and is fined away by pen core just can write, when 6-7cm used by pen, often thrown into dustbin because holding a pen inconvenience, volume cut after paper, wood chip cannot reclaim use especially, cause very large waste, and pencil-lead exposes easily disconnected core.Therefore, need a kind of continuous core, pen core utilization rate high, economize on resources, the pencil of environmental protection.

Summary of the invention

The object of the invention is for above-mentioned the deficiencies in the prior art, a kind of energy-conserving and environment-protective be provided, can improve pen core utilization rate be convenient to regulate the art pencil of pen core.

The object of the invention is to be achieved through the following technical solutions: a kind of art pencil being convenient to regulate pen core, comprise penholder, be placed in the pen core in penholder cavity and be placed in pen plug, the pen cap of penholder upper and lower end respectively, described pen cap is threaded in penholder lower end through pen core tip, it is characterized in that, pen core propulsion tube is provided with in described penholder cavity, described pen core propulsion tube cavity inner wall is provided with internal thread, described pen core is cylindrical, its sidewall is provided with the external screw thread matched with internal thread, and pen core is threaded in pen core propulsion tube.

Described pen core propulsion tube outer wall is provided with spacing block set, and pen core propulsion tube is fixed in penholder inner chamber by spacing block set.

Internal thread length in described pen core propulsion tube cavity is equal with the external thread length on pen core sidewall.

On described pen core and pen core propulsion tube, the spacing of adjacent thread is 3-6mm.

The diameter of described pen core is 0.3-20mm.

Described penholder cross section is quadrangle, hexagon or circle.

Described pen cap inwall minimum diameter place is provided with sandwich mouth.

Be provided with pen core sandwich device in described pen cap, pen core sandwich device is the tapered tubular matched with pen cap inwall tapering, and the maximum gauge place of pen core sandwich device is provided with defining flange.

In the present invention, the diameter of pen core is 0.3-20mm, and pen core is placed in pen core propulsion tube, and the internal thread of pen core propulsion tube and the external screw thread of pen core cooperatively interact.The present invention needs knockout in use, only need pin penholder on the other hand, pins the pen core be placed in outside pen cap on the other hand, and by rotating pen core clockwise or counterclockwise, pen core, under the cooperation of internal and external screw thread, constantly screws out outside pen cap, realizes the continuous knockout of pencil.The present invention, when not using, can pin penholder on the other hand, pins pen core on the other hand, and the counterclockwise or pen core that turns clockwise, returning pen core in penholder, guaranteeing pencil continuous core when not using.

The setting of pen core propulsion tube is that protection pen core is by its continuous core, and the spacing block set on pen core propulsion tube outer wall is to make pen core propulsion tube better be fixed in penholder in order to make pen core firm in penholder cavity.Internal thread length in pen core propulsion tube cavity is equal with the external thread length on pen core sidewall, even if pen core is also left several centimeters after using for a long time, also pen core can be screwed out penholder and continue outward to use.On pen core and pen core propulsion tube, the spacing of adjacent thread is 3-6mm, revolves the pen core that turns around, can ensure pen core knockout 3-6mm.

The present invention is skillfully constructed, and structure is simple, and manufacture easily, cost is low, continuous core, and pen core utilization rate is high, economizes on resources, environmental protection, has the wide market space.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention;

Fig. 2 is the structural representation of pen core propulsion tube in the present invention;

In figure: 1 penholder, 2 pen cores, 3 pen plugs, 4 pen caps, 5 pen core propulsion tubes, 6 spacing block sets, 7 pen core sandwich devices.

Detailed description of the invention

Be convenient to the art pencil regulating pen core, comprise penholder 1, be placed in the pen core 2 in penholder cavity and be placed in pen plug 3, the pen cap 4 of penholder upper and lower end respectively.The diameter of pen core is 0.3-20mm, and penholder cross section is quadrangle, hexagon or circle.

Be provided with pen core propulsion tube 5 in penholder cavity, pen core propulsion tube outer wall is provided with spacing block set 6, and pen core propulsion tube is fixed in penholder inner chamber by spacing block set.

Pen core propulsion tube cavity inner wall is provided with internal thread, pen core is cylindrical, its sidewall is provided with the external screw thread matched with internal thread, internal thread length in pen core propulsion tube cavity is equal with the external thread length on pen core sidewall, on pen core and pen core propulsion tube, the spacing of adjacent thread is 3-6mm, and pen core is threaded in pen core propulsion tube.

Pen cap is threaded in penholder lower end through pen core tip, pen cap inwall minimum diameter place is provided with sandwich mouth, be provided with pen core sandwich device 7 in pen cap, pen core sandwich device is the tapered tubular matched with pen cap inwall tapering, and the maximum gauge place of pen core sandwich device is provided with defining flange.

The present invention needs knockout in use, only need pin penholder on the other hand, pins the pen core be placed in outside pen cap on the other hand, and by rotating pen core clockwise or counterclockwise, pen core, under the cooperation of internal and external screw thread, constantly screws out outside pen cap, realizes the continuous knockout of pencil.The present invention, when not using, can pin penholder on the other hand, pins pen core on the other hand, and the counterclockwise or pen core that turns clockwise, returning pen core in penholder, guaranteeing pencil continuous core when not using.
