Abstract
A compensating pencil is mainly formed by integration of a pen pole, a core storage tube installed inside the pen pole, a core outlet device and a core locking device. The core outlet device mainly comprises a point sleeve arranged inside the pen pole, a compressed spring is placed inside the point sleeve, and a lead protection tube is connected to the rear end of the point sleeve. The compensating pencil is characterized in that the core locking device comprises a clamping head with a protrusion arranged on one end of the clamping head, the clamping head and a spring sleeved outside the clamping head are together placed inside a clamping head sleeve, the protrusion is matched with the inner wall of the clamping head sleeve, and the clamping head sleeve is connected with the core storage tube and matched with the lead protection tube. The compensating pencil is simple in structure, small in the number of parts, convenient and fast to disassemble and assemble, convenient to assemble on an assembly line, and suitable for bulk production and cost reduction of enterprises. The compensating pencil is strong in practicability, and especially suitable for being used by middle and elementary school students in the daily life and study.
Description
Technical field
The utility model relates to a kind of propelling pencil, particularly a kind of compensation pencil.
Background technology
Because of compensation pencil energy automatic makeup lead, sharpen a pencil without cutter, can long-time continuous write, save time, to save timber, the favor that deeply is subjected to the consumer easy to use, for making things convenient for the consumer to portably use, satisfy various arrangement of consumption persons' different demands, so various in style, the configurations of existing propelling pencil, have their own characteristics each.Wherein Chinese patent specification ZL200520013035.5 discloses a kind of compensation pencil, before the installation two ends are connected with respectively in penholder, rear retainer plate and with the core storage tube of lead for retractable pencil be fixed with rubber, cover has the rubber seat of rubber case, and be connected with out core apparatus, the integral body that lock core device consists of forms, describedly go out core apparatus and formed by the lead pipe that protects of placing with stage clip in the point cover, described lock core device is to be placed with steel ball in the dop one end groove, overcoat has spring, be placed in the coning sleeve with front plug, steel ball cooperates with the coning sleeve inwall, coning sleeve be connected with the front retainer plate of core storage tube end and with protect lead pipe and cooperate.But, adopting the compensation pencil of this structure, dop wherein need to arrange steel ball, therefore causes the above-mentioned shortcomings such as dop complex structure, complex production process, production cost height.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of compensation pencil is provided, and its part is few, and is simple in structure, easily assembling, and not easily broken core, practical, production cost is low, for market has increased again a kind of new fancy variety.
The technical scheme in the invention for solving the above technical problem is: a kind of compensation pencil, mainly by penholder, be installed in the core storage tube of penholder inside, the integral body that goes out core apparatus and lock core device formation forms, describedly go out core apparatus and comprise the point cover that is arranged on penholder inside, the inner stage clip of placing of point cover, protect the rear end that lead pipe is connected in the point cover, it is characterized in that: described lock core device comprises that an end is provided with the dop of projection, dop together is placed on the inside that dop overlaps with sheathed spring at it outside, projection cooperates with dop cover inwall, dop overlap be connected with core storage tube and with protect lead pipe and cooperate.
Above-mentioned compensation pencil, described core storage tube two ends are respectively arranged with forward and backward retainer plate, and core storage tube is connected with the dop cover by front retainer plate.
Above-mentioned compensation pencil, described dop cover is with front plug.
Above-mentioned compensation pencil is fixed with rubber, overlaps the rubber seat that rubber case is arranged on the described penholder.
Compared with prior art, the utility model has the advantage of: this compensation pencil adopts the end that the dop of projection is arranged, the dop of this type can pass through the mould one-shot forming, and adopts steel ball unlike prior art, also steel ball will be assembled on the dop except producing dop and steel ball.Dop of the present utility model and projection system thereof are wholely set, and it cooperates with dop cover inwall, has omitted the assembly process of producing steel ball and steel ball in the prior art, simultaneously because of projection and dop Integral design, material is also same with dop, and need not to select other metal materials, low production cost.Therefore compensation pencil parts of the present utility model are few, production is simple and easy, are convenient to assemble at streamline, and the batch production of suitable enterprise reduces again cost.
Description of drawings
For content of the present utility model is more likely to be clearly understood, the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings.
Fig. 1, structural representation of the present utility model (cutaway view)
Fig. 2, dop of the present utility model position enlarged diagram (cutaway view)
Fig. 3, dop of the present utility model position decomposing schematic representation
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Dop overlaps 8 outer surfaces two protruding buttons, and the corresponding protruding buckle of inwall has the tubular of an annular lip and tapering.
Lock core device is by directly arranging projection 10 on the dop 9, overcoat has spring 15, places the annular lip place in the dop cover 8, and the front plug 14 of through hole is arranged in the middle of an end of dop cover 8 also tightly is embedded with, and the tapering place that projection 10 is close on the dop cover inwall consists of.
Go out core apparatus and be comprised of the lead pipe 12 that protects that is equipped with stage clip 11 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 respectively two protruding buttons on the dop cover 8, in two rectangular openings of buckle on point cover 13, be fixedly connected into the pen head part that can not rotate, first 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 core storage tube 6 interior lead for retractable pencils 5 passes respectively dop 9, front plug 14, retaining core pipe 12 until outer confession of pen write.
When writing, lead for retractable pencil 5 contacts with paper and writes, lead for retractable pencil 5 is worn and touches paper until protect the end of lead pipe 12, protect the effect that lead pipe 12 is subject to upwards writing active force, move compression press spring 11 to penholder 4 interior directions, the front plug 14 of push card headgear 8 bottom surfaces, the dop cover is moved inward, produce frictional force between dop cover and projection, pass to the intermediate plate of dop 9, and under the effect of spring 15, lead for retractable pencil 5 outwards mobile distances can continue again to write, and so constantly circulation can be write for a long time, until a lead for retractable pencil writes, need take away first rubber when changing core, another new lead for retractable pencil is passed rear retainer plate successively, core storage tube, front retainer plate, dop, retaining core pipe is until outside the pen, and can not insert in the other direction, pass, to guarantee writing quality, during this pencil is suitable especially, the pupil uses in daily life and study.
