Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment 1: a kind of pen as depicted in figs. 1 and 2, comprises the front pen container 2 of hollow, the rear pen container 3 of hollow and pen core 1.Pen core 1 is arranged in the hollow inner side of front pen container 2 and rear pen container 3, and the rear end, inner side of rear pen container 3 is also fixed with the securing member 31 for fixing pen core, and pen core 1 rearward end is fixed in securing member 31.
The outer wall at front pen container 2 rear portion is provided with the limited impression 20 of ring-type, and the inwall of rear pen container 3 front end is provided with collar flange 30, and the front portion of rear pen container 3 is socketed on the outer wall at front pen container 3 rear portion, and collar flange 30 is positioned at limited impression 20.Due to the existence of this limited impression 20, after front pen container 2 and rear pen container 3 are socketed mutually, even if operator is when axially certain little strength is bestowed in opposing stretching, be also difficult to directly be pulled open separation.The state of not writing exposed the state of writing or be in nib hiding being in nib in order to ensure pen core 1 is all more stable, therefore on front pen container 2 outer wall of limited impression 20 upper end, be embedded with the first magnetic part 201 in the utility model, on front pen container 2 outer wall of limited impression 20 lower end, be embedded with the second magnetic part 202.Near rear pen container 3 outer wall of collar flange 30 be provided with respectively can with the 3rd magnetic part 301 of described first magnetic part 201, second magnetic part 202 phase adhesive.
In the present embodiment, the annulus that the first magnetic part 201 is iron hoop or is made up of multiple little iron block, the annulus that the second magnetic part 202 is also iron hoop or is made up of multiple little iron block, and parallel with the first magnetic part 201.The annulus that 3rd magnetic part 301 is permanent-magnetic clamp or is made up of multiple permanent magnets.
Securing member 31 is the cylinder of opening towards front side, and the opening of securing member is positioned at inside rear pen container 3; The inside of described cylinder is provided with the shoulder hole 311 for tight fit different size pen core; Axially when the front pen container 2 of opposing stretching and rear pen container 3, collar flange 30 can form interference fit, until deviate from described front pen container 2 outer wall after departing from from limited impression 20 rear end.
In addition, when imposing on the axial front pen container 2 of opposing stretching of larger strength and rear pen container 3, the collar flange 30 on rear pen container 3 can form interference fit with front pen container 2 outer wall after departing from from limited impression 20 rear end, until deviate from, but do not damage front pen container 2 and rear pen container 3.
Embodiment 2:
Different from embodiment 1, in the present embodiment, the annulus that the first magnetic part 201 is permanent-magnetic clamp or is made up of multiple permanent magnets, the annulus that the second magnetic part 202 is also permanent-magnetic clamp or is made up of multiple permanent magnets, and parallel with the first magnetic part 201.The annulus that 3rd magnetic part 301 is permanent-magnetic clamp or is made up of multiple permanent magnets.All the other are identical with embodiment 1.
Embodiment 3:
As shown in Figure 4, different from embodiment 1, in the present embodiment, the rear pen container 3 be positioned at below collar flange 30 is provided with axial extension 30a.The front pen container 2 being positioned at limited impression 20 bottom is provided with cannelure 20a.When rear pen container 3 pushes downwards, the 3rd magnetic part 301 and described second magnetic part 202 phase adhesive, axial extension 30a snaps in cannelure 20a.Particularly, cannelure 20a is the fluting of opening towards radial direction, and when rear pen container 3 pushes downwards, axial extension 30a is enclosed within fluting outside, is covered by fluting.Axial extension 30a herein coordinates with cannelure 20a and makes front pen container 2 and the axial uniformity of rear pen container 3 better, and before and after ensureing, pen container has good uniformity after engagement, there will not be radial cheap, keeps best writing effect.In addition, axial extension 30a is enclosed within fluting outside, and make the external diameter of axial extension 30a can be easy to be processed into the size identical with front pen container 2 external diameter, when making to write cooperation, penholder smooth outer surface, without step, promotes writing effect further.
Embodiment 4:
As shown in Figure 5, different from embodiment 3, the cannelure 20a in the present embodiment is the groove of opening towards axis, and when rear pen container 3 pushes downwards, axial extension 30a is embedded in groove.Axial extension 30a herein coordinates with cannelure 20a and makes front pen container 2 and the axial uniformity of rear pen container 3 better, and before and after ensureing, pen container has good uniformity after engagement, there will not be radial cheap, keeps best writing effect.All the other structures are identical with embodiment 3.
Embodiment 5:
As shown in Figure 3, different from embodiment 3, in the present embodiment, near limited impression 20 upper limb position and near limited impression 20 upper limb be respectively equipped with an annular convex 20c.When writing, between the annular convex 20c that after promoting, pen container 3 makes collar flange 30 be stuck in downside and limited impression 20 lower edge, nib exposes.When hiding pen core, retract rear pen container 3 or oppositely pull front pen container 2 and rear pen container 2, between the annular convex 20c making collar flange 30 snap in upside and limited impression 20 upper limb.So, the object of annular convex 20c and effect are to prevent pen to be in neither cartridge exposing using state non-concealed pen core state again, thus makes it well use in an orderly manner.
Above embodiment illustrates by way of example, and it can not as the restriction to this practicality.When not deviating from the utility model scope, its principal character may be used for various embodiment.
