Abstract

The utility model relates to a gravity induction writing component. The gravity induction writing component can be installed on various writing pens and is particularly applicable to a ball-point pen. The gravity induction writing component is characterized by comprising a cartridge sleeve, a cartridge inner pipe and a cartridge. The cartridge sleeve is a hollow pipe. A liming inner pipe is fixed on the inner wall of the bottom of the cartridge sleeve. The cartridge inner pipe is arranged inside the cartridge sleeve in a sleeved mode. The diameter of the cartridge inner pipe is larger than the inner diameter of the limiting inner pipe. The gravity induction writing component is superior to a cartridge extensible component of a traditional autopen. The gravity induction writing component is simple in structure, rapid and convenient to operate, durable and suitable for being used on the various pens in an installation mode, and the cartridge can be stretched out or withdrawn through a simple motion.

Description

A kind of gravity sensing writing nib

Technical field

The utility model relates to a kind of gravity sensing writing nib, can be arranged on all kinds of writing pens, is specially adapted to ball pen.

Background technology

The refill expansion modular construction of traditional mechanical pencil is complicated, and manufacture process requirement is high, and production cost is high, and the mode that button triggers is single, and easily damages in the process of Reusability.Lack automatic telescopic parts a kind of simple in structure, easy to use and reliable on market.

The utility model content

The purpose of this utility model is to overcome existing the problems referred to above in prior art, and a kind of reasonable in design, simple, convenient, practical gravity sensing writing nib are provided.

The utility model solves the problems of the technologies described above the technical scheme that adopts: this gravity sensing writing nib, it is characterized in that, comprise pen core sleeve pipe, pen core inner tube and pen core, described pen core sleeve pipe is hollow tube, be fixed with spacing inner tube on the inwall of this pen core sleeve bottom, described pen core inner tube is mounted in the pen core sleeve pipe, the diameter of pen core inner tube is greater than the interior diameter of spacing inner tube, the overall diameter of described pen core is less than the interior diameter of spacing inner tube, and pen core passes the pen core inner tube and is mounted in the pen core sleeve pipe.In use procedure when the afterbody of pen core withstands on spacing inner tube pen core lean out, when the afterbody of pen core slips into spacing inner tube, in pen core income pen core sleeve pipe.

As preferably, also include nib, pen point casing is placed on the top open part of pen core sleeve pipe, has out a hole on nib, and described pen core sleeve pipe, spacing inner tube and nib are on same central axis.Nib can be used as the location pen core, and can make pen core inner tube and pen core in the pen core sleeve pipe can not skid off.

As preferably, described pen core inner tube is the copper bourdon tube, can make this product more durable.

As preferably, also include pen core tail plug, the pen core tail has through hole beyond the Great Wall, and pen core tail plug plug is at the afterbody of pen core.

As preferably, described pen core tail plug is copper, and pen core mostly is the stressed easy distortion of flexible pipe, and the pen core tail plug of metal is more durable, and more easily is stuck on spacing inner tube.

As preferably, the bottom of described pen core sleeve pipe has pore, is for the pen core ventilation, is convenient to write.

The beneficial effects of the utility model are: be better than the refill expansion parts of traditional mechanical pencil, this product structure is simple, and is convenient to operation, more durable, is applicable to be arranged on the upper use of all kinds of pens, and a simple action just can be stretched out pen core or take in.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment: referring to Fig. 1-Fig. 7, the utility model embodiment comprises pen core sleeve pipe 1, pen core inner tube 2, pen core 3, nib 4 and pen core tail plug 5.

The pen core sleeve pipe 1 of this product is hollow tube, be fixed with spacing inner tube 7 on the inwall of this pen core sleeve bottom 6, pen core inner tube 2 is mounted in pen core sleeve pipe 1, and the diameter of pen core inner tube 2 is greater than the interior diameter of spacing inner tube 7, pen core inner tube 2 can be in the interior slip of pen core sleeve pipe 1, but can not slip into spacing inner tube 7; The overall diameter of pen core 3 is less than the interior diameter of spacing inner tube 7, and pen core 3 passes pen core inner tube 2 and is mounted in pen core sleeve pipe 1, and pen core 3 can be in the interior slip of pen core sleeve pipe 1.

This product also includes nib 4, and nib 4 is mounted on open top 8 places of pen core sleeve pipe 1, has out a hole 9 on nib 4, and pen core sleeve pipe 1, spacing inner tube 7 and nib 4 are on same central axis.Nib 4 can be used as the location pen core, and can make pen core inner tube 2 and pen core 3 in pen core sleeve pipe 1 can not skid off.

The pen core inner tube 2 of this product is the copper bourdon tube, pen core afterbody 3-1 also is plugged with pen core tail plug 5, have through hole 10 on pen core tail plug 5, pen core tail plug 5 is copper, and pen core 3 mostly is flexible pipe, stressed easy distortion, the pen core tail plug 5 of metal is more durable, and pen core 3 also more easily is stuck on spacing inner tube 7 simultaneously, and for pen core 3 ventilations, be convenient to write, the bottom of pen core sleeve pipe 1 has pore 11.

In use procedure, pen core sleeve pipe 1 is in heeling condition when this product is in when writing state as described in Figure 7, after 2 landings of pen core inner tube, pen core 3 also skids off from spacing inner tube 7, and when the pen core tail plug 5 of pen core afterbody 3-1 withstands on spacing inner tube 7, pen core 3 leans out, and can write; This product is turned around, and when product was in as shown in Figure 6 state, starting writing at action of gravitation withstood on after in-core pipe 2 slips on spacing inner tube 7, and pen core 3 slips into spacing inner tube 7 under the guiding of pen core inner tube 2 simultaneously, and this moment, pen core 3 namely was in the state of indentation.

Above content described in this specification is only to the explanation of the utility model structure example.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
