Abstract

The utility model relates to an automatic core propelling pencil which is composed of a core storing tube, an eraser seat and a whole body which is composed of a core propelling device and a core locking device, wherein the core storing tube is arranged in a pencil rod, both ends of the sore storing tube are respectively connected with a front and a back fixing rings and are provided with lead cords, the eraser seat is fixed with an eraser and is sheathed with an eraser sleeve. The core propelling device is composed of a lead protecting tube, wherein a pressure spring is arranged in a tip sleeve of the lead protecting tube, a steel ball is arranged in a groove which is arranged at one end of a clamping head of the core locking device and a spring is sheathed out of the groove. In addition, the core locking device is arranged in a taper sleeve which is provided with a front plug, the steel ball is matched with the inner wall of the taper sleeve and the taper sleeve is connected with the front fixing rings of one end of the core storing tube and is matched with the lead protecting tube. Although the automatic core propelling pencil does not have the function of changing cores automatically, the utility model has the advantages of simple structure, less parts and convenient and quick assembly and disassembly and is convenient to assemble on production lines. Thus, the utility model is suitable for producing in batches for enterprises and the cost can also be reduced. The pencil has strong practicability and is particularly suitable for middle school students and pupils in daily life and learning.

Description

The automatic propelling pencil

Technical field

The utility model relates to a kind of propelling pencil, particularly a kind of energy automatic propelling pencil.

Background technology

Because of the automatic propelling pencil can be mended lead automatically, sharpen a pencil without cutter, can long-time continuous write, save time, save timber, the favor that is subjected to the consumer deeply easy to use, for making things convenient for the consumer to portably use, satisfy various arrangement of consumption persons' different demands, thus existing propelling pencil various in style, structure is different, have their own characteristics each.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of automatic propelling pencil is provided, and its part is few, and is simple in structure, easily assembling, and not easily broken core, practical, for market has increased a kind of new fancy variety again.

The technical scheme in the invention for solving the above technical problem is: the automatic propelling pencil, before the installation two ends are connected with respectively in penholder, back retainer plate also has the core storage tube of lead for retractable pencil and is fixed with rubber, be with the rubber seat of rubber case, and be connected with out core apparatus, the integral body that lock core device constitutes is formed, describedly go out core apparatus and form by placing the lead pipe that protects that has stage clip in the point cover, described lock core device is to be placed with steel ball in the dop one end groove, be with spring outward, be placed in the coning sleeve of plug before having, steel ball cooperates with the coning sleeve inwall, coning sleeve be connected with the preceding retainer plate of core storage tube end and with protect lead pipe and cooperate.

Compared with prior art, advantage of the present utility model is: though this automatic propelling pencil does not have from moving the core function, but it is simple in structure, part is few, easily assembling, each part can be assembled into earlier independently parts separately, and then general assembly is made in penholder, promptly have rubber, the rubber seat of rubber case is a portion, before being connected with, the back fixedly core storage tube of astragal pen core is the pen core part, knockout, lock core device then pen core partly is loaded in the penholder, and the screw thread that pen head part utilization point puts is fixed on the end of penholder by the nib part that taper bushing on it and point cover connect into, the tight again portion of inserting of the end in addition of penholder, so easy accessibility, rapidly, be convenient to assemble on streamline, suitable enterprise produces in batches and reduces cost again.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Preceding retainer plate 7 is for there is shoulder hole the centre, and an end is cylindrical, and an end is the hexagon that outer surface has protruding reinforcing rib.Back retainer plate 16 is for there is shoulder hole the centre, and an end has the tubular of concave surface.

Point cover 13 1 ends are Taper Pipe, and an end is for to have screw thread, opening part periphery that the tubular of two uniform rectangular through-hole arranged outward.

Dop 9 is closed up by the two halves intermediate plate has the ladder of through hole cylindrical in the middle of being assembled into, and there is a semi-circular recesses per half intermediate plate outer surface lower end, and upper end-face edge has a plane of being convenient to install.

Coning sleeve 8 outer surfaces have two protruding buttons, and the corresponding protruding buckle of inwall has the tubular of an annular lip and tapering.

Core storage tube 6 two ends tightly have the forward and backward

retainer plate

7,16 of through hole to constitute the pen core part in the middle of the cover respectively.

Rubber 7 is fixed in the through hole of rubber seat 3 one ends, and the ornamental rubber case 2 of outer tight cover constitutes a portion.

Lock core device is embedded with steel ball 10 by the groove on the dop 9, is with spring 15 outward, places the annular lip place in the coning sleeve 8, and the preceding plug 14 of through hole is arranged in the middle of an end of coning sleeve 8 also tightly is embedded with, and the tapering place that steel ball 10 is close on the coning sleeve inwall constitutes.

Go out core apparatus and be made up of the lead pipe 12 that protects that band stage clip 11 is installed in the point cover 13, protect lead pipe 12 1 ends for conical, an end is columniform ladder pipe, and stage clip 11 places in the cylindrical pore.

Lock core device, go out core apparatus and utilize two protruding buttons on the coning sleeve 8 respectively, in two rectangular openings of buckle on point cover 13, be fixedly connected into the pen head part that can not rotate, earlier pen core partly is installed in the penholder 4, tightly respectively at the two ends of penholder again insert a portion and with the fixing pen head part of screw thread, an end of lead for retractable pencils 5 passes dop 9, preceding plug 14, retaining core pipe 12 respectively and supplies to write outside pen in the core storage tube 6.

When writing, lead for retractable pencil 5 contacts with paper and writes, lead for retractable pencil 5 is worn and touches paper up to the end of protecting lead pipe 12, protect the effect that lead pipe 12 is subjected to upwards writing active force, direction moves compression press spring 11 in penholder 4, promote the preceding plug 14 of coning sleeve 8 bottom surfaces, coning sleeve is moved inward, produce frictional force between coning sleeve and steel ball, pass to the intermediate plate of dop 9, and under the effect of spring force 15, lead for retractable pencil 5 outwards moves a distance, can continue again to write, and so constantly circulation can be write for a long time, write up to a lead for retractable pencil, need take away rubber earlier when changing core, another new lead for retractable pencil is passed the back retainer plate successively, core storage tube, preceding retainer plate, dop, retaining core pipe is outside pen, and opposite direction can not be inserted, pass, to guarantee writing quality, during this pencil is suitable especially, the pupil uses in daily life and study.
