CN204774222U - Prevent falling pen socket - Google Patents

Abstract

The utility model relates to a prevent falling pen socket comprises the spherical heavy burden cavity that cup joints the cylindrical inner chamber that is made by the flexible glue at the pen end and link to each other rather than the integration, the inner chamber is hollow structure, and hollow portion's radius and radius are unanimous, and the inner chamber is less than the inner chamber through a radius connection chamber links to each other with the heavy burden cavity of rear end, has placed the heavy burden thing in the heavy burden cavity to guarantee that the terminal weight of pen is more than nib weight. Have extension pen life, avoid characteristics such as nib damage, convenience safe in utilization, economic environmental protection.

Description

A kind of Anti-breaking pen cap

Technical field

The utility model belongs to pen cap technical field, relates to a kind of Anti-breaking pen cap.

Background technology

The nib of pen is very fragile, in use from table fall on the ground if nib touch ground so this pen substantially just can not employ, a lot of people has experience similar like this, is also the service life greatly reducing pen for this reason, is also unfavorable for energy-conserving and environment-protective.

Utility model content

In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of Anti-breaking pen cap, and it can be enclosed within the rear end of pen, by increasing the weight of a rear end, thus the end of pen first lands when making to drop, thus nib is avoided to land causing pen to break down the problem that cannot use.

The utility model solves the technical scheme that its technical problem adopts: a kind of Anti-breaking pen cap, by being socketed in cylindrical cavity that an end obtains by flexible glue and the spherical heavy burden cavity that be connected integrated with it is formed, described inner chamber is hollow structure, and the radius of hollow space is consistent with a radius, inner chamber is connected by the heavy burden cavity of connection chamber and rear end that a radius is less than inner chamber, in heavy burden cavity, be placed with heavy burden thing, thus ensure that the weight of an end is much larger than nib weight.

The length of described inner chamber is longer than the length of nib, thus can be socketed on nib when non-working condition and use as cap.

The width of described heavy burden thing is greater than the width of connection chamber, thus ensures that heavy burden thing can not drop out in heavy burden cavity.

The beneficial effects of the utility model are: can guarantee that pen is first landed by an end when dropping to ground by this pen cap, the heavy burden cavity made due to the flexible glue adopted and inner chamber, therefore any damage can not be caused to the end of pen, guarantee the integrality of whole pen, have extend pen service life, avoid the features such as nib damages, safe and convenient to use, economic environmental protection.

Accompanying drawing explanation

Fig. 2 is the utility model using state figure.

In figure: 1-inner chamber , 2-heavy burden cavity , 3-connection chamber , 4-heavy burden thing.

Detailed description of the invention

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

See Fig. 1, a kind of Anti-breaking pen cap, by being socketed in cylindrical cavity 1 that an end obtains by flexible glue and the spherical heavy burden cavity 2 that be connected integrated with it is formed, described inner chamber 1 is in hollow structure, and the radius of hollow space is consistent with a radius, inner chamber 1 is connected by the heavy burden cavity 2 of connection chamber 3 and rear end that a radius is less than inner chamber 1, is placed with heavy burden thing 4 in heavy burden cavity 2, thus ensures that the weight of an end is much larger than nib weight.

The length of described inner chamber 1 is longer than the length of nib, thus can be socketed on nib when non-working condition and use as cap.

The width of described heavy burden thing 4 is greater than the width of connection chamber 3, thus ensures that heavy burden thing 4 can not drop out in heavy burden cavity 2.

Can guarantee that pen is first landed by an end when dropping to ground by this pen cap, the heavy burden cavity 2 made due to the flexible glue adopted and inner chamber 1, therefore any damage can not be caused to the end of pen, guarantee the integrality of whole pen, have extend pen service life, avoid the features such as nib damages, safe and convenient to use, economic environmental protection.

Claims (3)

1. an Anti-breaking pen cap, it is characterized in that: by being socketed in cylindrical cavity that an end obtains by flexible glue and the spherical heavy burden cavity that be connected integrated with it is formed, described inner chamber is hollow structure, and the radius of hollow space is consistent with a radius, inner chamber is connected by the heavy burden cavity of connection chamber and rear end that a radius is less than inner chamber, in heavy burden cavity, be placed with heavy burden thing, thus ensure that the weight of an end is much larger than nib weight.

2. Anti-breaking pen cap as claimed in claim 1, is characterized in that: the length of described inner chamber is longer than the length of nib, thus can be socketed on nib when non-working condition and use as cap.

3. Anti-breaking pen cap as claimed in claim 1, is characterized in that: the width of described heavy burden thing is greater than the width of connection chamber, thus ensures that heavy burden thing can not drop out in heavy burden cavity.
