Description

Ball point pen

The utility model relates to a kind of ball point pen technical field of writing.

Ball point pen is a kind of pen practical in the daily writing instrument, more common in the market ball point pen mostly is plug-in type greatly and connects, ball point pen BAOZHU519 as nearest production, this pen is made up of a body, the pen cap and ball-point-pen core, the jointing of pencil lead is with being threaded in the middle of wherein having only a body and locking a body, and a body is connected with the mode of inserting with the pen cap, though it is simple in structure, advantage such as easy to use, but it is often firm inadequately that this insertion connects, and the pen cap, written easy to crack, the pen cap is also lost easily, so service life is shorter.

The purpose of this utility model is to overcome above-mentioned shortcoming, and provide a kind of each section header whole ball point pens that are threaded that adopt, connect closely stable, firm, simple in structure between this ball point pen screw thread, be specially adapted to fish formula ball point pen, and use very convenient.

For achieving the above object, the technical solution of the utility model is such: this ball point pen, comprise by a body, the pen cap and ball-point-pen core are formed, it is characterized in that: a body head is built-in with an inserts, this inserts stretches out from a body head cross section centre and the direction vertical with cross section, and extension is shaped on internal thread and external screw thread, this ball point pen also includes one externally threaded joint, the external screw thread of this joint is connected with the internal thread of above-mentioned inserts is suitable, the pen cap also has an inserts of opening internal thread on cross section, the internal thread of described inserts is connected with the external screw thread of above-mentioned inserts is suitable.

As further improvement of the utility model, place an outer surface of the metal insert of body head endoporus and place the metal insert outer surface of pen cap head endoporus to have that the shallow annular groove makes and a body or pen cap endoporus between fix more firmly, stable.Certainly, the metal insert outer wall of this body recited above or the pen cap can also be the ring profile of tooth.

Adopt the ball point pen of above-mentioned this full thread formula connected mode because connection power is strong, in conjunction with closely, stable, thereby avoided losing the pen cap or the pen cap, the pen clip cracking phenomena takes place.And simple in structure, use very conveniently, suitable especially fish formula ball point pen adopts.

Description of drawings:

Fig. 1. the ball point pen full view of the utility model outward appearance whale fish.

Fig. 2. Fig. 1 porpoise ball point pen is along the amplification view of A-A line.

Below in conjunction with description of drawings embodiment of the present utility model is further described.

Ball point pen is the complete fish formula ball point pen that fish body and fish tail adopt thread connecting mode that fish body and fish tail are linked together as shown in fig. 1.Form by a body 2, the pen cap 3 and pen core 1 at the whale formula ball point pen shown in Fig. 2, body head is built-in with a metal insert 6, this inserts stretches out from a centre, body head cross section and the direction vertical with the cross section, and extension has internal thread and external screw thread, have in the pen cap head with the cross section and place the metal insert 5 of opening internal thread on the same plane, the internal thread of this inserts is connected with the external screw thread of body metal insert is suitable, also has one and have only externally threaded metal joint 4 between this body and the pen cap.The suitable connection of extension internal thread of the external screw thread of joint and a body metal insert.Place the metal insert in the body head and place the outer wall of the metal insert in the pen cap head that shallow annular groove or ring tooth are arranged, inlay respectively in a fish body body endoporus or fish tail pen cap endoporus.

During use, hold the fish body on the other hand gently, another hand takes off the pen cap by counterclockwise rotating fish tail, can write, and uses very convenient.

Certainly, outer the moulding of this metal insert can also be adopted other structure, and as how forked, same, a body metal insert or pen cap metal insert also can adopt other material, and as organic molecule, such variation all drops within the protection domain of the present utility model.
