Description

Portable integrated pen shell

Technical field

The utility model relates to study article field, in particular to a kind of portable integrated pen shell.

Background technology

In the learning life of people, often can use gel ink pen, such as, when writing, can pen be used.Current pen needs nib to screw down usually when exchanging pen core for, easily lose and the nib that drops, and this brings inconvenience to the life of people.

Utility model content

The purpose of this utility model is the integrated pen shell providing a kind of portable, the problem that when exchanging pen core at present for improve, nib easily drops.

The utility model is achieved in that

A kind of portable integrated pen shell, comprise inner layer case and outer shell, described inner layer case is nested with described outer shell, it is characterized in that, described outer shell two ends are provided with screw thread, described threads mates with described inner layer case screw thread, and described inner layer case also comprises tail end knob and clamp, and described clamp is away from knob.

Further, described outer shell comprises shell housing, shell head end and tail end, and shell head end is provided with external screw thread, and shell tail end is provided with internal thread.

Further, described inner layer case also comprises housing parts, and described housing is used for connecting described clamp and screw thread;

The clamp of described inner layer case contacts with outer shell, and described clamp can slide in outer shell, and in use, the maximum radius of described clamp is greater than the radius of fillet of described outer shell tail end, thus ensure that inner layer case can not drop.

Further, described shell also comprises nib, and one end of described nib is provided with the second round mouth;

The other end of described nib is also provided with the first round mouth and internal thread, and described first round mouth mates with the head end of described outer shell, and the screw thread of described first round mouth also mates with the head end screw thread of described outer shell.

Further, described shell also comprises cap, and described cap opening mates with described nib, and described cap also comprises block rubber, gluing bottom described block rubber and described cap, thus can protect the nib of pen core in use.When cap covers, block rubber and written close contact, thus can effectively reduce pen core ink leak.

Compared with prior art, the beneficial effects of the utility model:

The shell that the utility model provides utilizes inner layer case, and making, when dismounting pen core, does not need nib to be unloaded the object that just can reach change-fountain pen core, more convenient and swift.In addition, in use, the screw thread that arranges of inner layer case and outer shell can degree of tightness between free adjustment pen core and a shell.

Detailed description of the invention

Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.

Embodiment 1

Consult Fig. 1-Fig. 3 and Fig. 8, the portable integrated pen shell that the utility model provides comprises inner layer case 103 and outer shell 102, and inner layer case 103 is nested with outer shell 102.Shell also comprises nib 101 and cap 104, and nib 101 is mated with cap 104, nib 101 can described outer shell 102 to be threaded, outer shell 102 and written 101 housings jointly surrounded can be used as the complete housing of inner layer case 103.

The inner layer case 103 that can extract out can play connection, iris action.When people are when using pen to write, inner layer case 103 is threaded with outer shell 102 and ensures that pen core can not spill, and pen core and extraneous obstruct is come.When pen core changed by needs, inner layer case 103 can be extracted out from outer shell 102, now, inner layer case 103 serves the connection function with outer shell 102, prevents inner layer case 103 to drop.

When the pen is not in use, in order to prevent the clean and tidy problem of the ink leak of pen core and placement, being provided with cap 104, decreasing inconvenience when pen does not use, add the practicality of a shell.

Embodiment 2

The portable integrated pen shell that consulting Fig. 4-Fig. 7 the utility model provides comprises inner layer case 103 and outer shell 102, and inner layer case 103 is nested with outer shell 102.Shell also comprises nib 101 and cap 104, and nib 101 is mated with cap 104, nib 101 can described outer shell 102 to be threaded, outer shell 102 and written 101 housings jointly surrounded can be used as the complete housing of inner layer case 103.

In the implementation case, inner layer case screw thread 302 is connected with outer shell tail end 202, and outer shell head end 201 coordinates with written first round mouth 401, and arc clamp 301 is slidably connected with the inner surface of outer shell.

When change-fountain pen core, turn inner layer case knob 303 counterclockwise, inner layer case 103 is extracted out, arc clamp 301 maximum radius is greater than outer shell tail end 202 radius of fillet, ensure that inner layer case can not drop out, now, the old pen core of taking-up, puts into new pen core from outer shell tail end 202.

After new pen core is put into, inner layer case is pushed back, turn inner layer case knob 303 clockwise, be screwed onto till pen core metal penpoint part all exposes.

Because arc clamp 301 and outer shell tail end 202 screw thread can cause wearing and tearing in long-time use, in order to the situation preventing arc clamp 301 and outer shell tail end 202 thread abrasion from causing inner layer case to drop out, the shell in the present embodiment has also done corresponding improvement for this situation.Be provided with the ridge 203 mated with arc clamp 301 at the inner surface of outer shell, ridge 203 arranges the wearing and tearing that can reduce arc clamp 301 pairs of outer shell tail end 202 screw threads, further increases the service life of a shell.The setting of ridge, further prevents rocking arbitrarily of inner layer case 103, thus can improve the stability of inner layer case 103.

When pen does not use, block rubber 502 and pen core close contact that cap 104 is arranged, can reduce the ink leak of pen core effectively, cap skin is also provided with one deck rubber jar, be used for reducing skidding when using, the even mass distribution of a shell, improves the practicality of a shell.

The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
