Abstract

The utility model discloses a prevent falling a shell belongs to stationery technical field, a prevent falling a shell, including tail-hood, pen-holder, nib, screw thread, balancing weight, the pen-holder is hollow cylinder, the top of pen-holder is provided with the tail-hood, and the end of pen-holder is provided with the nib, the terminal surface in top of pen-holder is provided with the screw thread, the inside balancing weight that is provided with of top tail-hood of pen-holder. Set up a balancing weight through the top end at the pen-holder, and then changed the whole focus of pen for the focus position is located near the end of pen-holder, when the pen drops carelessly, has contacted the ground the position and has taken place the change, makes the nib can not take place direct collision with ground, and then has played the effect of preventing falling.

Description

Anti-falling pen shell

Technical Field

The utility model belongs to the technical field of stationery, concretely relates to prevent falling a shell.

Background

The water-based pen or the cylindrical pen is most commonly used in the current office, the common structure is that the pen core is a fixed structure and is provided with a pen cap, the pen cap is often forgotten to be covered by a user in the using process, when the pen falls on the ground, the pen point is easy to lose in an unprotected state, once the pen point is damaged, the pen core cannot be used any more, and the service life of the pen is seriously shortened.

Most of existing anti-falling pens are complex in structure, and due to the fact that some complex mechanical structures or magnetic anti-falling structures are adopted, the cost is greatly increased, mass production cannot be achieved, and large-scale application is conducted.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a prevent falling a shell to the nib breaks easily among the solution prior art, and current prevents falling a problem that the structure is complicated, with high costs.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an anti-falling pen shell, includes tail-hood, pen-holder, nib, screw thread, balancing weight, the pen-holder is hollow cylinder, the top of pen-holder is provided with the tail-hood, and the end of pen-holder is provided with the nib, the terminal surface in top of pen-holder is provided with the screw thread, the inside balancing weight that is provided with of top tail-hood of pen-holder.

Preferably, the tail cover is internally provided with internal threads.

Preferably, the balancing weight is a cylinder with the diameter of the lower part being the same as the inner diameter of the penholder, and the upper part of the balancing weight is a three-quarter cylinder structure.

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

set up a balancing weight through the top end at the pen-holder, and then changed the whole focus of pen for the focus position is located near the end of pen-holder, when the pen drops carelessly, the position of contacting to the earth has taken place the change, makes the nib can not take place direct collision with ground, and then has played the effect of preventing falling, and overall structure is simple, compares with traditional pen, has only increased a balancing weight, low cost, and is very practical.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is an exploded view of the structure of the present invention.

In the figure: 1-tail cover, 2-pen holder, 3-pen point, 4-screw thread and 5-counterweight block.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, in an embodiment of the present invention, an anti-falling pen case includes a tail cap 1, a pen holder 2, a pen point 3, a thread 4, and a weight block 5, the pen holder 2 is a hollow cylinder, a pen core is installed inside the pen holder, the tail cap 1 is disposed above the pen holder 2, an internal thread is disposed inside the tail cap 1, the thread 4 is disposed on the outer surface of the top end of the pen holder 2, and the tail cap 1 and the pen holder 2 are connected through a thread, which is simple and convenient.

The tail end of the penholder 2 is provided with a pen point 3.

The internal portion of the tail cover 1 above the pen holder 2 is provided with a balancing weight 5, the diameter of a cylinder below the balancing weight 5 is the same as the internal diameter of the pen holder, the upper portion of the balancing weight 5 is of a three-quarter cylinder structure, the diameter of the cylinder above the balancing weight is slightly smaller than the internal diameter of the tail cover 1, the tail end of the balancing weight 5 is inserted into the internal portion of the pen holder 2, and the balancing weight is stably fixed at the tail end of the pen holder 2 through the tail cover 1.

The utility model discloses a theory of operation is: set up a balancing weight 5 through the top end at pen-holder 2, changed the focus position of pruning pen for the focus takes place the skew toward the terminal direction in pen-holder 2 top, and then, when the pen dropped, the position of nib can not directly bump with ground, caused the damage of nib, thereby protected the nib, played the function of preventing falling.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
