Abstract

The utility model relates to a ball pen, particularly a ball pen with a changeable ball pen core and a correction structure. The compromise joint of the ball pen is provided with the outer margin of a key and an outer screw part, and the liquid containing barrel of the utility model is provided with a protrusion and a threaded hole. The protrusion of the liquid containing barrel is matched and connected with the connecting hole of the pen holder, the threaded hole of the liquid containing barrel is connected with the outer screw part of the compromise joint, and the outer margin of the key of the compromise joint is connected with the internal keyway of the correction pen head. Thus, the correction function is convenient to be used, the correction structure is easy to clean, the correction liquid is easy to refill, and the cost is reduced.

Description

Ball pen with removable correction structure

The utility model relates to a kind of ball pen, refers to that especially interchangeable refill for ball-point pen is again with the ball pen of altering structure.

At present, ball pen commonly used does not possess the correction structure, but by bottled correction fluid, alters wrongly written character with Correction brush (or writing brush) libation at an ancient wedding ceremony liquid, not only uses inconvenience, and operates waywardly, causes waste easily, even mistake; In recent years, also begin pen type structure by the dress correction fluid, upper and lower to press by drawing the liquid bar, correction fluid is flowed out, but the dry and hard or foreign material that correction fluid often occurs stop up fluid hole, make the pen type structure can not continue to use and cause waste, moreover after correction fluid uses up, can not refill liquid easily, also cause waste (disposable use), simultaneously, must finish correction fluid is in an independent structure, still not too convenient during use.

In view of this, the purpose of this utility model provides a kind of ball pen with removable correction structure, and first-class structure of correction pen and liquid filling cylinder are easily taken apart, and liquid filling cylinder directly is connected ball pen container top again.

The purpose of this utility model is achieved in that a kind of ball pen with removable correction structure comprises penholder, refill for ball-point pen, correction nib, transition joint and liquid filling cylinder, and transition joint has key outer rim and external thread part, and liquid filling cylinder has convex and screw; The convex of liquid filling cylinder and the connecting hole of penholder are connected, and the screw of liquid filling cylinder is connected with the external thread part of transition joint, and the key outer rim of transition joint is connected with the internal keyway of altering nib.

The convex of above-mentioned liquid filling cylinder is that cylindrical thread is connected or circular cone connects with the connecting hole of penholder.

Owing to adopt such scheme: alters easy to usely, and correction structure easy cleaning and adorn correction fluid again reduces cost.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model exemplary embodiments structural representation.

Among the figure: 1, penholder 11, connecting hole 2, refill for ball-point pen 3, alter nib 31, internal keyway 32, fluid hole 33, lever shoulder 4, draw liquid bar 5, helical spring 6, transition joint 61, key outer rim 62, external thread part 7, liquid filling cylinder 71, convex 72, screw.

The closed top end of penholder 1 has connecting hole 11, and this connecting hole 11 can be the cylinder screw, also can be the garden taper hole, also can not want connecting hole 11, and remainder is a prior art.

Refill for ball-point pen 2 belongs to prior art.

Alter nib 3 (rigid members) upper end inner edge and have internal keyway 31, and lower end fluid hole 32 and top, lower end lever shoulder 33 all belong to prior art.This correction nib 3 also can adopt elastomer (as: rubber), does not just need to draw liquid bar 4 and helical spring 5.

Draw liquid bar 4 and belong to prior art.

Helical spring 5 belongs to prior art.

Indirect 6 one ends have key outer rim 61 and internal keyway 31 (obstructed keyway can prevent leakage) be connected (with face of cylinder close fit, and key connecting can prevent to be subjected to rotate than high pulling torque); The other end is an external thread part 62.

Liquid filling cylinder 7 is that the dress of an end opening is altered fluid cylinder, and blind end has convex 71 (cylindrical thread or nose cone) and is connected with the connecting hole 11 of penholder 1 or is connected, and also can be provided with convex 71, and the direct and penholder 1 of liquid filling cylinder 7 makes an integral body; Openend has screw 72 and is connected with the external screw thread 62 of transition joint 6, and dismounting liquid filling cylinder 7 convenience oneself can be adorned correction fluid again or clean transition joint 6, alter nib 3 etc., makes to alter structure and be unlikely to be subjected to correction fluid to stop up or correction fluid uses up and scraps.
