Description

pen

This creative department is related to stationery, and more specifically refers to a pen.

Press, the pen is one of the most important stationery when writing. At present, the pen that is the easiest to obtain and the most convenient to use is a ballpoint pen (or ballpoint pen, ballpoint pen or oil pen...etc.).

However, the structure of the conventional ball pen is mainly composed of a tube and a pen core placed in the pen tube, and the pen tip of the pen has a steel ball exposed outside the pen tube to utilize the steel ball on the surface of the object. Rolling takes the ink out. However, if the ball pen is accidentally dropped on the ground, the steel ball is easily exposed by the steel ball, and the steel ball is damaged or contracted, resulting in leakage or inability to write.

Therefore, there is a common ballpoint pen, which is provided with a button on the axial end of the pen tube. When the button is pressed, the pen tip of the pen can be pushed out to the outside of the pen tube, and when pressed, the button can be pressed. Recycle the tip of the pen to the inside of the pen tube for recycling. Therefore, when not in use, the pen tip can be retracted into the pen tube for protection, so as to avoid the above-mentioned direct impact on the steel ball. However, it is not only when the tip of the pen is indented that the fall occurs, when the user is When writing (that is, when the tip of the pen is exposed and fixed), the pen can be accidentally dropped from the hand and dropped to the ground. At this time, the steel ball may be damaged by the impact, or the user is not used. When the pen is pressed, the pen tip of the pen is not pressed back to the retracted state. If the pen is dropped, the ball will be damaged by the impact.

In view of this, in order to improve the prior art, the conventional ball pen is susceptible to damage when dropped; thus, the present invention provides a pen comprising: a tube having an axial through hole and a diameter a pressing hole connected to the through hole; a center of the heart is placed in the through hole of the pen tube, and can be reciprocally displaced along the through hole at a retracted position to an extrapolated position by an external force; a sliding member, Attached to the through hole of the pen tube and sleeved outside the pen, the outer surface of the sliding member has at least one first inclined surface; a resilient member is abutted against the wall surface of the through hole of the pen tube Between the sliding members, a pressing member is movably disposed in the pressing hole of the pen tube, and has at least one second inclined surface that abuts against the first inclined surface of the sliding member; when the pressing member is not When the force is applied, the sliding member and the pen core are moved to the retracted position by the elastic force of the elastic member, so that the pen core is retracted into the through hole of the pen tube, and when the pressing member is stressed, the second The inclined surface pushes the first inclined surface to move the sliding member and the pen to the extrapolated position, so that the pen core protrudes An outer tube through hole of the pen.

In the above pen, the through hole of the pen tube has a front end hole connected to the outer end of the pen tube and a receiving hole communicating with the front end hole, and the hole diameter of the receiving hole is larger than the hole diameter of the front end hole; The pressing hole extends radially inward from one side surface of the pen tube to communicate with the receiving hole of the through hole; the sliding member is located in the receiving hole The elastic member has one end abutting on a class surface formed between the receiving hole and the front end hole, and the other end abuts on an axial end surface of the sliding member.

The pen further includes a sleeve; the through hole of the pen tube has a rear end hole connected to the outer end of the pen tube, and the receiving hole is connected between the front end hole and the rear end hole; the pen sleeve is sleeved At the rear end of the pen tube, the rear end hole is closed.

In the above pen, the pen has a tip and a pen body connected to the pen tip; the slider is sleeved with the pen body; when the pen core is in the retracted position, the pen tip is retracted to the pen In the through hole, when the pen core is in the extrapolated position, the pen tip protrudes outside the through hole.

In the above pen, the inside of the sliding member has an axially extending sleeve hole, and the sleeve is connected by the pen core fastening sleeve to be interlocked.

In the above pen, the elastic member is a spring.

In the above pen, when the pen core is in the retracted position, the second inclined surface of the pressing member is pushed by the first inclined surface of the sliding member to perform radial movement, and the pressing member is pushed out toward the pressing hole.

When the user wants to put down the creation or suddenly inadvertently release the creation, the elastic member can automatically push the pen inward, and the pen tip of the pen is inwardly exposed to prevent the pen from being in the state. When a caution is dropped, there is a situation in which the tip of the pen is injured. In the present invention, the second inclined surface of the pressing member and the first inclined surface of the sliding member are mutually abutted, which is not only convenient to use, but also requires a simple structure, and the manufacturing cost can be greatly reduced.
