Abstract

A retractable pen used for writing on a touch screen includes a pen point, a pen tube, a pen holder and a pen tail, wherein the pen point is arranged on front end of the pen tube; the pen holder is arranged in the pen tube and is slidingly connected with the pen tube, and pen tail is arranged on the tail part of the pen holder; characterized in that the front end of the pen holder arranged in the pen tube is provided with two grooves, and each groove is provided with an elastic silastic ring; the elastic silastic ring is connected with the inner wall of the pen tube in an interference contact manner. The pen has advantages that each elastic silastic ring is provided with two or three surfaces contacting with the inner wall of the pen tube to play a function of stabilizing the pen, when the pen is unfolded completely; there is non swinging between the pen tube and the pen holder basically so as to write stably.

Description

A kind of scalable pen that is used on touch-screen, writing

(1) technical field:

The utility model relates to a kind of device that is used for touch-screen, especially a kind of scalable pen that is used on touch-screen, writing, and it can be used for smart mobile phone, instant translator, palm PC etc.

(2) background technology:

At present, the plastic ring 8 of scalable (see figure 1) on the market is connected with the shaft of a writing brush 6 of thick-wall tube by interference fit, and in use penholder 9 is together with very easily pull-off from the shaft of a writing brush 6 of plastic ring 8.Rubber ring 7 (see figure 2)s only are housed in the groove of penholder 9, thus after the whole assembling when pen all launches between the shaft of a writing brush 6 and the penholder 9 the meeting generation greatly rock, cause the instability of pen when writing.And owing to rubber ring 7 large tracts of land contact with the shaft of a writing brush 6 inwalls, thus quite high to the accuracy requirement of rubber ring 7, cause the difficulty in the processing to strengthen processing cost.

(3) utility model content:

The purpose of this utility model is to provide a kind of scalable pen that is used for writing on touch-screen, it can solve the deficiencies in the prior art, reaches the stable purpose of pen when writing, and long service life.

The technical solution of the utility model: a kind of scalable pen that is used on touch-screen, writing, comprise whole pen by nib, the shaft of a writing brush, penholder and a tail, said shaft of a writing brush front end is equipped with nib; Said penholder is contained in and is sliding connection in the shaft of a writing brush, and the penholder afterbody is adorned by a tail; The front end that is contained in part in the shaft of a writing brush that it is characterized in that penholder has the twice groove, and two elastic silicone rubber circles are installed respectively in the groove; Said elastic silicone rubber circle is the interference contact with shaft of a writing brush inwall and is connected.

The part that above-mentioned said elastic silicone rubber circle contacts with shaft of a writing brush inwall is two or three faces.

The silicon rubber hardness of above-mentioned said elastic silicone rubber circle is 70 degree.

The above-mentioned said shaft of a writing brush adopts thin-wall metal tube, and there is an in-flanges its afterbody port, as the stop means that prevents penholder pull-off from the shaft of a writing brush.

The inwall of the above-mentioned said shaft of a writing brush scribbles the silica-based railway grease of lubricate.

Superiority of the present utility model: 1, each elastic silicone rubber circle has two or three faces to contact with shaft of a writing brush inwall, has played stabilization, can not produce basically between the shaft of a writing brush and the penholder when pen all launches and rock, and reaches the stable purpose of pen when writing; 2, the in-flanges of the shaft of a writing brush has certain width to reduce penholder friction when flexible in the shaft of a writing brush; 3, the silicon rubber hardness of the material of elastic silicone rubber circle employing is 70 degree, and its performance is better than other resilient material, good heat resistance, and high life, hardness is higher not yielding; 4, silica-based railway grease plays lubrication, can suitablely slide freely when penholder is flexible, and silica-based railway grease heat-resisting quantity is good, is difficult for overflowing from the shaft of a writing brush hand is made dirty when higher temperature.
