Abstract

The utility model discloses a pen provided with an inserted refill and dispensing with a nib sleeve, which comprises a pen holder and the refill. The refill further comprises a refill rod and a refill head; the refill rod extends into a rod barrel of the pen holder, and the refill head extends out of the rod barrel; and a clamp body is arranged at the connection part of the refill rod and the refill head, the refill rod, the refill head and the clamp body are integrally formed, and the tail part of the clamp body is connected with an outlet of the rod barrel of the pen holder in an interference fit manner. The clamp body added on the pen refill is in interference fit with the rod barrel of the pen holder, and the pen refill is fixedly installed on the pen holder, so that the nib sleeve is directly omitted; the clamp body, the refill rod and the refill head are integrally formed, and accordingly, the pen refill is directly connected with the pen holder in a matching manner by means of the structure of the pen refill, so that the structure of an original pen is simplified greatly, simultaneously, the production cost is reduced, the assembling procedure is simplified, the labor cost is saved, and the pen is worth popularization and application.

Description

A kind of pen core plug-in type can be economized the pen of point cover

Technical field

The utility model relates to the pen technology field, says that more specifically a kind of pen core plug-in type can economize the pen of point cover.

Background technology

Pen, it is indispensable stationery in the middle of our daily life, put down in writing in the patent ZL201020289925.X that the structure of conventional pen such as the applicant apply in the early time, comprise the cap for brush, sharp cover, penholder and pen plug, point cover and pen plug are located at respectively the two ends of penholder, and the cap for brush is sheathed on and is positioned at the sharp place end that overlaps on penholder.

In a system process, send into the assembly shop after the parts castings such as point cover and penholder, this moment, the assembler need to be connected in one they both, and the connected mode of conventional point cover and penholder is two kinds: one is interference fit, need to be with in point cover insertion penholder; It two is threaded engagement, the point cover need to be screwed into outside penholder.

Above, all illustrated after the parts difference castings such as point cover and penholder, all need the assembler that they are connected in series, so more or less taken many human resources, increased production cost.

The utility model content

The purpose of this utility model is to overcome above defective, provide a kind of simple in structure, easily manufactured, assembling easily, low production cost, in assembling process, the less pen core plug-in type of required human resources can be economized the pen of point cover.

In order to reach above purpose, the utility model is achieved through the following technical solutions: a kind of pen core plug-in type can be economized the pen of point cover, comprises penholder and pen core, and pen core further comprises core bar and core print, core bar stretches in the bar cylinder of penholder, and core print stretches out outside the bar cylinder of penholder; It is characterized in that, be provided with on the connecting portion between described core bar and core print and aforementioned both integrated cramping bodies, the bar cylinder exit interference fit of the afterbody of described cramping body and described penholder is connected.

The utility model is by setting up cramping body on pen core and the bar cylinder interference fit of penholder, pen core is fixedly mounted on penholder, directly saved sharp cover, and cramping body and front core bar and core print are one-body molded, and pen core like this utilizes self structure directly and penholder is connected, and has greatly simplified the structure of original, when having reduced production cost, simplified assembly process, saved labor cost, be worthy of popularization very much.

As preferably, described cramping body is crowded around by the rib shape muscle that protrudes laterally from the connecting portion between core bar and core print and is consisted of, and the anterior external diameter of described cramping body is greater than the afterbody external diameter.

Disclosed because of carelessness in the military service process of pen core in penholder bar cylinder and damaged pen, thus the anterior external diameter of cramping body greater than the afterbody external diameter, thereby damage pen even adopt again large external force also to be difficult to pen core is disclosed in penholder bar cylinder.

As preferably, the bar cylinder exit inner face of penholder is matsurface.

The technology that adopts matsurface is mainly to make the cramping body on pen core closely cooperate with the bar nozzle of penholder, and the principle of its utilization is increase frictional force.

As preferably, the filling of the afterbody of penholder has pen plug, and the middle part of penholder is arranged with the soft plastic cover, and the front portion of penholder is arranged with the cap for brush.

The soft plastic cover is to prevent that the user from writing the generation of skidding in process, and the cap for brush is to exist in order better to protect pen core, is to be in manufacturing process to consider as for pen plug.

Beneficial effect: the utility model is by setting up cramping body on pen core and the bar cylinder interference fit of penholder, pen core is fixedly mounted on penholder, directly saved sharp cover, and cramping body and front core bar and core print are one-body molded, and pen core like this utilizes self structure directly and penholder is connected, and has greatly simplified the structure of original, when having reduced production cost, simplified assembly process, saved labor cost, be worthy of popularization very much.
