Abstract

A novel anti-dropping pen is characterized in that a raised fitting rod (1) is arranged in the centre at the tail end of a pen holder (4); a weight cap (3) with a groove (2) matched with the fitting rod (1) at the bottom thereof is nested on the fitting rod (1); a spring (5) is arranged between the bottom of the groove (2) and the top of the fitting rod (1); a conical barrel (6) with a bigger front diameter and a smaller rear diameter is sleeved in front of the weight cap (3) on the tail part of the pen holder (4); a recess (8) is arranged inside the conical barrel (6); and the pen holder (4) is provided with a collision bead (7) which is at the recess (8) of the corresponding conical barrel (6). The utility model has the advantages of simple structure and strong practicality; and in addition, when the pen is dropped carelessly, the conical barrel fast bounces up, so that the pen head is effectively protected from damage and the pen is more endurable.

Description

Novel shatter-resistant pen

Technical field

The utility model relates to pen, is a kind of novel shatter-resistant pen specifically.

Background technology

Pen is common is now used by people, and its advantage is a fluent writing.The producer that has also is made into senior gold fountain pen to pen, as the present good merchantable brand.Used the people of pen all to know, pen is without falling.Particularly nib just can not have been used later in case fallen once again.If the gold fountain pen of a costliness, that is just very unfortunate.There is a kind of top band heavily to cut or polish jade with an emery wheel the pen of cap at present, can make pen in the whereabouts, heavily cut or polish jade with an emery wheel one on cap and land earlier, beat but this pen but can not prevent secondary, just working as an accent lands, when upwards being rebounded by ground, its accent one end can be played De Genggao, like this when for the second time born again, fountain pen nib can land earlier undoubtedly, can damage nib equally, so, need a kind of improved novel shatter-resistant pen.

Summary of the invention

The purpose of this utility model provides a kind of novel shatter-resistant pen of practicality.

Described novel shatter-resistant pen, it is characterized in that: the penholder of this pen is the thin column structure in preceding thick back, be provided with the loop bar of a projection at the tail end center of this penholder, the heavily stone roller cap that bottom surface has with the supporting groove of loop bar is nested on the loop bar, is provided with spring between the end face of the bottom surface of groove and loop bar; The pre-large post-small taper casing of diameter is placed in the dead ahead that the penholder afterbody is heavily cut or polish jade with an emery wheel cap, is provided with pit in the taper casing, and penholder is provided with and bumps pearl, describedly bumps the pit that pearl is positioned at corresponding taper casing; The point diameter of described penholder is between the last bore and following bore of taper casing.

The utility model is simple in structure, and is practical, when throwing pen carelessly, has cylinder to upspring rapidly, effectively protects fountain pen nib not to be damaged, and makes pen more durable in use.

Description of drawings

Fig. 1 is the utility model structural representation,

Fig. 2 is that the utility model is protected written view.

Among the figure: the 1-loop bar, 2-groove, 3-are heavily cut or polish jade with an emery wheel cap, the 4-penholder, the 5-spring, 6-taper casing, 7-bumps pearl, the 8-pit.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified: novel shatter-resistant pen described in Fig. 1, Fig. 2, it is characterized in that: the penholder 4 of this pen is the thin column structure in preceding thick back, be provided with the loop bar 1 of a projection at the tail end center of this penholder 4, the heavily stone roller cap 3 that bottom surface has with loop bar 1 supporting groove 2 is nested on the loop bar 1, is provided with spring 5 between the end face of the bottom surface of groove 2 and loop bar 1; The pre-large post-small taper casing 6 of diameter is placed in the dead ahead that penholder 4 afterbodys are heavily cut or polish jade with an emery wheel cap 3, is provided with pit 8 in the taper casing 6, and penholder 4 is provided with and bumps pearl 7, describedly bumps pit 8 places that pearl 7 is positioned at corresponding taper casing 6; The point diameter of described penholder 4 is between the last bore and following bore of taper casing 6.Heavily cutting or polish jade with an emery wheel cap 3 adopts overweight metal to make.

As shown in fig. 1: heavily cut or polish jade with an emery wheel cap 3 and be nested on the loop bar 1, heavily cut or polish jade with an emery wheel between cap 3 and the loop bar 1 and also leave the space.

When pen is thrown, whole pen is when falling downwards, because the effect of aerostatic buoyancy, the tail end that density is big will be rapidly down, and heavily cutting or polish jade with an emery wheel cap 3 will land in advance.

When heavily cutting or polish jade with an emery wheel cap 3 and land, the reaction force that ground produces can make heavily cuts or polish jade with an emery wheel cap 3 bullets to loop bar 1, and spring 5 is compressed simultaneously, heavily cuts or polish jade with an emery wheel cap 3 and hits taper casing 6, washes away to the nib end along penholder 4 rapidly after taper casing 6 is stressed.Because in the design; the lower end diameter of penholder 4 is between the last bore and following bore of taper casing 6; taper casing 6 is flushed to the front end that just is stuck in penholder 4 at last; the part of going out penholder 4 like this just in time plays a kind of protective effect to nib; just land, upspring for the first time, when landing for the second time; taper casing 6 will and separate on every side with nib, is protecting nib not to be damaged.Fig. 2 is the guard mode of 6 pairs of nibs of taper casing.

The effect of bumping pearl 7 is under normal condition, is embedded in the pit 8 of taper casing 6, makes it and can not arbitrarily move.

Claims

1. novel shatter-resistant pen, it is characterized in that: the penholder of this pen (4) is the thin column structure in preceding thick back, be provided with the loop bar (1) of a projection at the tail end center of this penholder (4), the heavily stone roller cap (3) that bottom surface has with the supporting groove of loop bar (1) (2) is nested on the loop bar (1), is provided with spring (5) between the end face of the bottom surface of groove (2) and loop bar (1); The pre-large post-small taper casing (6) of diameter is placed in the dead ahead that penholder (4) afterbody is heavily cut or polish jade with an emery wheel cap (3), be provided with pit (8) in the taper casing (6), penholder (4) is provided with and bumps pearl (7), describedly bumps the pit (8) that pearl (7) is positioned at corresponding taper casing (6) and locates; The point diameter of described penholder (4) is between the last bore and following bore of taper casing (6).
