Abstract
The utility model relates to a pen, particularly a telescopic pen which can be conveniently carried and hung, wherein the length of a pen holder of the telescopic pen can be changed. The telescopic pen comprises a pen shell, a pen cap and a pen core arranged in the pen shell, wherein a sleeve tube is arranged in the pen shell and a guide slot is arranged on the sleeve tube. A connecting body is clamped in a guide groove. The connecting body is connected with a telescopic tube of the pen core by screws, and the telescopic tube of the pen core is arranged in the sleeve tube in which the pen core is arranged. The utility model mainly provides a pen which has simple structure, reasonable design and is convenient to carry and hang, wherein the length of the pen holder of the pen can be changed.

Description
Technical field
The utility model relates to a kind of pen, especially relates to a kind ofly can being convenient for carrying suspension, and the penholder length flexible pen that can become.
Background technology
In current society everywhere as seen tool is the indispensable part of people's daily life, and the pattern of pen, material, and function is convergence diversification more also.The length of pen has generally just been worked out in manufacture process, in general Bi length is immutable, for the people of all ages and classes section, uses the requirement of the length of pen also different, wish when child uses that penholder is shorter, wish that penholder is longer when using and be grown up.And because handwriting is longer, carrying neither be very convenient.The mode of existing control pen core turnover pen container mostly is two kinds, and a kind of is spring force by spring, pushes the turnover that button is controlled pen core; Second kind for to control the turnover of pen core by rotating lower pen body.The structure of these two kinds turnover pen cores is all comparatively complicated.
Summary of the invention
The utility model mainly provides a kind of simple in structure, and is reasonable in design, and penholder length is by flexible variable, and the pen that is easy to carry and hangs, and it is immutable to solve the existing penholder length of prior art, and the structure of pen is the complicated technology problem comparatively.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of telescopic pen, comprise a shell, the cap for brush and be located at the interior pen core of a shell, be provided with sleeve pipe in described the shell, sleeve pipe is provided with gathering sill, is connected with connector in gathering sill; The refill expansion pipe that has been threaded with connector, it is located in the sleeve pipe, is provided with pen core in it.By the slip of connector in gathering sill, drive the motion of refill expansion pipe, thereby change the length of penholder.Stretch and come out to make penholder length to become original twice, the convenient use shunk and entered to make the length of penholder to shorten, and is convenient for carrying.Because the frictional force between connector and gathering sill makes the refill expansion pipe stretch out the unlikely feasible shell landing in back, and the length of penholder can not be kept.The user only need spur the length that nib just can change penholder.The outer shape of shell can be known arbitrary shape, and as circle, polygon etc., the shape of a shell, sleeve pipe, refill expansion pipe is roughly the same.The material of shell and sleeve pipe can be the same or different, and general shell is metal material, or adopts and spray paint or spray-bonding craft makes, and sleeve pipe is plastics or resin material.
The number of the gathering sill on the sleeve pipe is at least one, and as preferably, the number of the gathering sill on the described sleeve pipe is two, and two gathering sills are oppositely arranged, and an end of gathering sill seals an end opening, and openend is towards a shell bottom.Two gathering sills can well guarantee guidance quality, and manufacturing process is also comparatively simple simultaneously; Gathering sill stretch out end sealing towards the refill expansion pipe, be for the extension elongation to the refill expansion pipe positions, the unlikely refill expansion pipe that makes is all pulled out a shell; The other end opening of gathering sill is convenient in order to assemble connector in a shell.If the equal opening in the two ends of gathering sill then will stretch out an end at the refill expansion pipe and be provided with a catch, prevent that the refill expansion pipe from pulling out long.
As preferably, described refill expansion pipe is provided with the stop bit projection towards the cap for brush one end, and the refill expansion length of tube is equal to or less than the length of a shell.Near an end of the cap for brush stop bit projection being set at the refill expansion pipe, is in the refill expansion pipe is retracted into a shell time, blocks a shell outer end, makes the refill expansion pipe be unlikely to be absorbed in fully in the shell, conveniently pulls out the refill expansion pipe simultaneously.Can certainly the length with a shell that the length of refill expansion pipe is made is identical, do not use the stop bit projection not cause the refill expansion pipe to be fully retracted so yet, cause stretching not come out.
The shape of connector can be identical with the shape of sleeve pipe, also can be different, and as preferably, the shape of connector is identical with sleeve-shaped, is provided with the clamping projection at its outer surface, and the clamping projection is connected in the gathering sill.Identical with the shape of sleeve pipe, connection and use are all comparatively convenient, cooperate also better.
As preferably, described sleeve pipe is an interference fit with a shell, is interference fits between refill expansion pipe and sleeve pipe.A sleeve pipe and a shell interference fit make sleeve pipe be fixed in the shell, thereby guarantee that connector drives a refill expansion pipe turnover shell by gathering sill, makes the penholder length variations.
As preferably, the described cap for brush is provided with hanger, is connected with lanyard on the hanger.The hanger lanyard is set on the cap for brush, makes things convenient for the user to carry and hang.
As preferably, the thickness of described sleeve pipe is 0.3mm-1mm.It is very thin that sleeve pipe is done, and it is very light to make that whole handwriting shows, and structure is also more compact.
Therefore, the utlity model has simple in structurely, reasonable in design, easy to use, can change the length of penholder, simultaneously, the utlity model has advantage easy to carry by stretching.
Description of drawings:
Accompanying drawing 1 is the whole cutaway view of a kind of telescopic pen of the present utility model;
Accompanying drawing 2 is dispersion design of part figure of a kind of telescopic pen of the present utility model;
Accompanying drawing 3 is the structural representations that stretch out of a kind of telescopic pen of the present utility model.
The concrete example of implementing:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
